  Therefore, there is a need for a device for adapting the shutter device to these changes when the external environment of the shutter device changes or when the shutter device ages.

  An object of the present invention is to provide a switchgear which can be adapted to changes in the external environment and aging, and a method of repairing the same.

  An opening and closing device according to the present invention includes an opening and closing body that is open and close movable, and an opening and closing machine having a brake device for stopping and moving the opening and closing body by turning on and off; , A mechanical control device for mechanically controlling the open / close device, and a slide control member which is slidable to switch off, and the open / close member is disposed, the open / close member being closed and moved The sliding member is made to slide on the string-like member by mechanically coupling the opening-closing member and the string-like member when contacting an obstacle present in the moving path of the opening-closing member on the way And a mechanical coupling device for causing tension force for turning on the brake device to be exerted by the own weight of the opening and closing body, wherein the mechanical control device and the mechanical coupling device , Is characterized in that at least one device is changed.

As described above, when there is a change in the external environment of the switchgear or when the switchgear is aged, it is necessary to adapt the switchgear to the change in the external environment or the aged change.

  In the switchgear according to the present invention, at least one of the mechanical control device and the mechanical coupling device provided in the switchgear is modified in order to adapt to these changes.

  Therefore, according to the switchgear according to the present invention, the switchgear can be adapted to changes in the external environment and aging.

  Here, to "change" that "device has been changed", the existing device (some or all) may be changed to a device (a device) having a different form and structure from this existing device. Besides, repairing existing equipment (some or all) may be repaired (including replacing with new ones (devices)), or existing equipment (some or all) In other words, simply moving (in other words, relocating) from the place where the existing apparatus was provided to another place.

  The above-mentioned “changing an existing device to a different type or structure from this existing device” or “repairing an existing device” may be accompanied by movement, and is not necessary. May be In addition, in the above-mentioned “moving simply the existing device from the place where the existing device was provided to another place”, maintenance of the existing device (for example, maintenance such as inspection, repair, maintenance, etc.) or Modification may or may not be accompanied by modification (e.g., addition, modification, deletion of functions).

  In the opening and closing device according to the present invention, as described above, "at least one device of the mechanical control device and the mechanical coupling device is changed". Therefore, in the opening and closing device according to the present invention The first change pattern "The mechanical coupling device has not been changed, and only the mechanical control device has been changed" in the "changed" pattern, and the "mechanical control device has not been changed." There is a second change pattern in which only the mechanical coupling device is changed, and a third change pattern in which both the mechanical control device and the mechanical coupling device are changed.

  In the first modification pattern described above, the type and structure of the mechanical coupling device which is not modified may be arbitrary, and the first example is provided with a pair of clamping members disposed on the opening and closing body, and is closed. The tension force acts on the string-like member by the pair of sandwiching members sandwiching the string-like member when the moving opening / closing body abuts against the obstacle. Further, in the second example of the type and structure of the mechanical coupling device which is not changed, there are provided a plurality of tooth portions on the outer peripheral portion, and a rotating member which is rotated by the string-like member when moving the opening / closing body; The rotating member includes an engaging portion engageable with the tooth portion, and the closing member in motion is moved when it abuts against the obstacle, and the engaging portion is moved by the movement. And a lock member engaged with the tooth portion to make the rotating member unrotatable.

  On the other hand, in the second modification pattern or the third modification pattern described above, the type and structure of the mechanical coupling device after modification may be arbitrary, and the first example is that a plurality of teeth are provided on the outer peripheral portion A rotating member that is provided with a rotating member that is rotated by the string-like member when the opening and closing body moves, and an engaging portion that can be engaged with the teeth of the rotating member.

In addition, the second example of the type and structure of the mechanical coupling device after being changed includes a pair of clamping members disposed on the opening and closing member, and the opening and closing member in the closing movement contacts an obstacle. When the pair of clamping members clamp the string-like member, tension acts on the string-like member.

  In any of the first to third change patterns described above, it is delayed from the removal of the obstacle that the slide member switches the braking device from on to off and the opening / closing body is resumed due to the removal of the obstacle. A delay device for initiating at least one of the at least one device before and after the change (of the at least one device). You may or may not do so.

  That is, in any of the first to third modification patterns described above, at least one of the delay device is selected before the modification of the at least one device described above and after the modification of the at least one device described above. It may or may not be provided after this change.

  To this end, the pattern in which the delay device is provided (in other words, installed) is a first installation pattern of “provided after the modification of the at least one device” and “the at least one device”. There is a second installation pattern, which is provided "before and after the change".

  In the method of repairing a switchgear according to the present invention, the "nonfunctionalization" of "nonfunctionalize (in other words, nullify the equipment)" means existing (in other words, existing) equipment In addition to leaving the device as it is (for example, breaking it or cutting the wiring) as well as leaving the device as it is, the existing device (one or the other) may be used. Removal of the device from the place where the switchgear was provided (in other words, the repair site), and the like.

  In addition, in "Change" to "Change to another device from this device", the existing device is changed to a device (device) having a different form and structure from this existing device, and an existing device. Replacement with a new one (apparatus).

  In the invention described above, the delay device (including the delay device before being changed and the delay device after being changed if it is changed) may be of any type and structure, and the delay device For example, the mechanical device may be a mechanical device using a viscous fluid resistance, a mainspring timer, or the like, or may be an electrical device using an electrical timer.

  A more specific example of the former case is that the delay device includes a viscous fluid damper, which has a one-way clutch, which exerts a tension on the string-like member. When it does, the delay action by the viscous fluid is not generated, and when the tension of the string-like member disappears, the delay action by the viscous fluid is generated.

  The damper may be a rotary damper in which a blade that rotates in the viscous fluid via a one-way clutch is attached to the rotation center axis.

  In this case, the delay device is configured to include a pivoting member for transmitting the rotation to the rotation center axis of the rotary type damper, and when the pivoting member acts on the tension force on the string-like member It may be rotated in one direction, and may be rotated in the other direction opposite to the one direction when the tension of the string-like member disappears.

  In the present invention, the mechanical coupling device (including the mechanical coupling device before being changed and the mechanical coupling device after being changed if it is changed) is disposed at an arbitrary position of the opening and closing body. In the case where the opening / closing body is configured to include the opening / closing body main portion and the opening / closing body sub-portion provided movably with respect to the opening / closing body main portion, It may be an opening and closing body main part or an opening and closing body sub part. However, when the mechanical coupling device is disposed in the opening / closing body main part, the part of the opening / closing body that moves by coming into contact with the obstacle during the closing movement of the opening / closing body is the opening / closing body subportion Since it is not the main part, the mechanical coupling device can be prevented from moving at the time of contact with an obstacle. Thereby, the structure for making the opening / closing body and the string member mechanically coupled by the mechanical coupling device can be simplified.

  Further, in the present invention, when the closing movement direction of the opening / closing body is downward, the opening / closing body is configured to include the opening / closing body main body and the end member disposed below the opening / closing body main body The end member includes a fixed portion fixed to the opening / closing body, and a movable portion disposed below the fixed portion and movable in the vertical direction with respect to the fixed portion. The opening / closing body main portion can be formed by the opening / closing body main body and the fixed portion, and the movable portion can be the opening / closing body sub-portion.

  According to this, when the opening / closing body is moving in the closing direction, the fact that the opening / closing body abuts against the obstacle existing in the closing direction means that the movable portion serving as the opening / closing body sub-portion abuts the obstacle Therefore, the movement of the opening / closing body sub-portion relative to the opening / closing body main portion due to the obstacle can be performed more reliably.

  Further, the present invention can be applied to any opening and closing device, and an example of the opening and closing device is a shutter device in which the opening and closing member is a shutter curtain, and another example is a smokeproof hanging wall device The present invention can be applied to various switchgears.

  Further, the opening and closing movement direction of the shutter curtain may be vertical or horizontal. When the opening and closing movement direction of the shutter curtain is the vertical direction, the closing direction of the shutter curtain may be downward or upward.

  Furthermore, at least one of the opening movement and the closing movement of the shutter curtain may be performed by the driving force of the electric motor device provided in the opening / closing device, or may be performed manually.

  When the opening and closing movement direction of the shutter curtain is vertical and the closing movement is downward, the closing movement may be performed by the weight of the shutter curtain, or by the weight of the shutter curtain. The driving force of the electric motor device provided in the opening / closing device may be added.

  Also, the means for stopping the shutter curtain in the downward direction before closing and moving to the fully open position may be a brake device of an opener, or an end member provided at the closing end of the shutter curtain, etc. The locking means may be provided with a locking member that locks onto the shutter curtain component.

  Furthermore, the opening and closing movement of the shutter curtain may be performed by winding and unrolling the shutter curtain by the take-up shaft, or the opening movement of the shutter curtain reaches a fully closed position as in the overhead door. Or the opening movement of the shutter curtain may be performed while maintaining the same shape (including some deformation but including substantially the same shape) as the overall shape of the shutter. The curtain may be deformed while being bent or the like, or a plurality of constituent members such as a panel constituting the shutter curtain are connected at the time of closing movement of the shutter curtain, and at the time of opening movement of the shutter curtain (storage of the shutter curtain So that they separate from one another and that these components overlap in the thickness direction You can have me.

  In addition, the opening and closing movement of the shutter curtain is performed by winding and unwinding the shutter curtain by forward and reverse rotation of the winding shaft, and the downward closing movement of the shutter curtain is the shutter curtain's own weight or this weight plus the electric motor of the opening and closing machine As for the shutter device which is driven by the driving force of the device, the take-up shaft is provided with a return spring by a torsion coil spring or a mainspring spring whose return force is accumulated during closing movement of the shutter curtain. The movement may be performed using the return force accumulated in the return spring as an auxiliary force.

  A shutter box 8 is disposed in the ceiling space 7 partitioned by the ceiling member 5 with respect to the entrance 2 and this shutter box 8 is shown in FIG. 2 which is a cross-sectional view taken along line S2-S2 of FIG. As it is, it is couple | bonded with the couplers 10, such as a volt | bolt, to the building housings 9, such as a down wall, which exists in the ceiling space 7. As shown in FIG. A take-up shaft 11 is horizontally accommodated inside the shutter box 8. The take-up shaft 11 is rotatably supported by left and right side surface parts 8A and 8B of the shutter box 8 shown in FIG. There is. Further, as shown in FIG. 1, an open / close machine 13 is connected to one end of the winding shaft 11 via a driving force transmission means 12 by a sprocket wheel and a roller chain. The switchgear 13 serving as a drive device for driving the take-up shaft 11 is also shown in FIG. 2, and the rotational force of the drive shaft 14 of the switchgear 13 is a drive sprocket attached to the drive shaft 14 A driving force transmission means 12 is constituted by a wheel 12A, a driven sprocket wheel 12B attached to the one end of the winding shaft 11, and an endless roller chain 12C bridged between the sprocket wheels 12A and 12B. Then, it is transmitted to the winding shaft 11.

  In addition, as shown in FIG. 2, the opening / closing machine 13 of the present embodiment is attached to the bracket member 15 which is coupled to one of the left and right side surface portions 8A and 8B of the shutter box 8. ing.

  As can be seen from FIG. 2, the shutter curtain 1 is wound around the winding shaft 11, and the upper end of the shutter curtain 1 is coupled to the outer peripheral surface of the winding shaft 11. Further, a portion of the shutter curtain 1 below the winding shaft 11 is suspended downward of the ceiling member 5 through a slit 17 provided in the lint 16 disposed in the ceiling member 5, and further, the shutter Both ends in the width direction of the curtain 1 are slidably inserted into the left and right guide rails 6 as described above. The immovable member tugs 16 such as the tugs or the like which are upper side forming members forming the upper side of the entrance 2 which is the opening, are formed by the tuft members 16A and 16B disposed opposite to each other, and these tuft members 16A and 16B Between the slits 17.

  FIG. 3 is a cross-sectional view showing the internal structure of the opening / closing machine 13. As shown in FIG. 3, the opening / closing machine 13 is a direct or alternating electric motor apparatus 18 and a brake apparatus 19 axially arranged in parallel, and the above-mentioned drive shaft 14 is an electric motor apparatus. The rotating shaft is fixed at the center of the eighteen rotating rotors 18A. A disc-shaped brake shoe 20 which is a first brake member is coupled to an end of the drive shaft 14 on the brake device 19 side. The brake device 19 is provided with a brake shaft 21 which is slidable by a fixed distance in the axial direction, and the brake shaft 22 is a brake drum 22 which is a second brake member facing the brake shoe 20 in the axial direction. Are combined. The brake shaft 21 and the brake drum 22 in the normal state are pressed toward the electric motor device 18 by the spring 23. Therefore, the brake device 19 is turned on by the pressure contact between the brake shoe 20 and the brake drum 22. Therefore, the drive shaft 14 of the electric motor device 18 at this time does not rotate by the braking force of the brake device 19.

  On the other hand, when the solenoid 24 disposed in the brake device 19 is energized, the magnetic force of the solenoid 24 causes the brake shaft 21 and the brake drum 22 to slide away from the electric motor device 18 against the spring 23. Therefore, the pressure contact between the brake shoe 20 and the brake drum 22 is released, and the brake device 19 is turned off. Therefore, at this time, the drive shaft 14 of the electric motor device 18 can be rotated by energization of the coil 25.

  As described above, when the solenoid 24 is energized, the brake device 19 is turned off, and when the energization is stopped, the brake device 19 is turned on. Therefore, the brake device 19 is electrically turned on and off. ing.

  In one of the left and right building housings 3 shown in FIG. 1, the shutter curtain 1 is opened upward and moved relative to the entrance 2, and is moved downward and stopped, and stopped. An operating device 30 is attached for performing the operation. The operation device 30 is provided with an "open" button, a "close" button, and a "stop" button. The shutter curtain 1 occupies most of the area of the shutter curtain 1 and has a curtain main body 1A whose upper end is coupled to the take-up shaft 11, and a seat plate 1B provided at the lower end of the curtain main body 1A. And has become. The curtain main body 1A of the present embodiment is formed by arranging a large number of slats in series up and down.

  The curtain main body 1A is an opening and closing body main body in the present embodiment, and the seat plate 1B is an end member in the present embodiment.

  When the shutter curtain 1 reaches the height position of the rim 16 disposed on the ceiling member 5 as described above, or when the seat panel 1B is shown in FIG. When the “close” button is operated when the shutter curtain 1 is in the semi-closed state (half-opened state) when the shutter curtain 1 reaches a halfway position, the controller 27 receives a signal from the “closed” button. Since the solenoid 24 is energized, the brake device 19 is turned off. As a result, the shutter curtain 1 causes the take-up shaft 11 and the drive shaft 14 to rotate forward by its own weight and is drawn downward from the take-up shaft 11, whereby the shutter curtain 1 moved closed is in the fully closed position. When it reaches, the control device 27 shown in FIG. 1 which receives a signal from a sensor (not shown) which detects the fully closed position shuts off the energization of the solenoid 24, and the brake device 19 is turned back on by the spring 23 ". In addition, when the shutter curtain 1 is fully closed, or as shown in FIG. 1, the shutter curtain 1 is in the half-opened state (where the seat plate 1B reaches an intermediate position between the lint 16 and the floor 4) In the semi-closed state), when the “open” button is operated, the solenoid 24 of the brake device 19 is energized by the control device 27 that receives a signal from the “open” button, so the brake device 19 is turned off The control device 27 energizes the coil 25 of the electric motor device 18. For this reason, the drive shaft 14 is reversely rotated, and this rotation is transmitted to the winding shaft 11 via the above-described driving force transmission means 12, and the shutter curtain 1 is rotated to the winding shaft 11 by the reverse rotation of the winding shaft 11. Take up and move open. When the shutter curtain 1 reaches the fully open position, the control device 27 receiving a signal from a sensor (not shown) that detects the fully open position shuts off the energization to the solenoid 24 and the brake device 19 is turned on by the spring 23. The controller 27 cuts off the energization of the coil 25.

  In addition, if the “stop” button is operated while the shutter curtain 1 is in the closing movement, the control device 27 that receives a signal from the “stop” button shuts off the energization to the solenoid 24. Is turned back on by the spring 23, the shutter curtain 1 stops at that position. Furthermore, if the "stop" button is operated while the shutter curtain 1 is moving open, the control device 27 that receives a signal from the "stop" button shuts off the energization to the solenoid 24. Is returned to the on state by the spring 23, and the control device 27 interrupts the energization of the coil 25 of the electric motor device 18, whereby the shutter curtain 1 stops at that position.

  Note that, as shown in FIG. 1, an electric circuit such as a relay circuit or a control device 27 by a computer is attached to the opening / closing machine 13, and the control device 27 The brake device 19 is electrically controlled. The control device 27 may be attached to a member, means, device or the like different from the opening / closing machine 13, and the arrangement location thereof is arbitrary.

  As can be understood from the above description, the floor 4, the guide rail 6, the shutter box 8, and the lint 16 and the like described above are immovable with respect to the shutter curtain 1 that moves open and closed. The guide rails 6, the shutter box 8, and the tines 16 are fixed members for the shutter curtain 1.

  As described above, the take-up shaft 11, which rotates in forward and reverse directions, is provided with a return spring by a torsion coil spring or a spring with which a return force is accumulated during the closing movement of the shutter curtain 1. The opening movement may be performed using the return force accumulated in the return spring as an auxiliary force.

  Further, as shown in FIG. 3, a lever member 31 is disposed at an end of the brake shaft 21 opposite to the electric motor device 18. The lever member 31 penetrates the brake shaft 21 and includes a first portion 31A and a second portion 31B which are divided with the brake shaft 21 as a boundary. A first bent portion 31C is formed in the first portion 31A, and a second bent portion 31D is formed in the second portion 31B. When a load acts on the first portion 31A in the A direction, that is, on the side opposite to the electric motor device 18, the first portion 31A swings in the A direction with the second bending portion 31D as a fulcrum, so the brake shaft 21 and the brake drum 22 slide in the A 'direction which is the same direction as the A direction. Therefore, the brake device 19 can be turned off without energizing the solenoid 24.

  The application of the load in the A direction to the first portion 31A in this manner is performed by an automatic closing device 32 described later attached to the opening and closing machine 13. The automatic closing device 32 is a mechanical control device for mechanically controlling the opening and closing machine 13 which is a driving device for driving the shutter curtain 1 as understood from the description below.

  Also, when a load in the same direction as the A direction acts on the second portion 31B, the second portion 31B swings in the same direction as the A direction with the first bending portion 31C as a fulcrum, so in this case as well, the brake shaft 21 and the brake drum 22 slide in the A 'direction. Therefore, the brake device 19 can be turned off without energizing the solenoid 24 also at this time.

  Applying a load in the same direction as the A direction to the second portion 31B in this manner can be performed manually. Therefore, the open / close machine 13 according to this embodiment can turn off the brake device 19 even by a manual operation. The second portion 31B may be omitted leaving the second bent portion 31D.

The curtain main portion 71A is an opening and closing body main portion in the present embodiment, and the curtain sub portion 71B is an opening and closing member sub portion in the present embodiment.

  As shown in FIG. 8, the fixing portion 70A of the seat plate 1B is formed by inner and outer members 75 and 76 both having a box shape in cross section, and the outer member 75 is divided in the thickness direction of the shutter curtain 1 The two divided members 75A, 75B are formed, and the divided members 75A, 75B are coupled to the lower end portion of the curtain main body 1A by a connector 77 such as a bolt or a nut. Therefore, the seat plate 1B is attachable to and detachable from the curtain body 1A. The lower surfaces of the inner and outer members 75 and 76 form an opening 78, and the upper end of the rising portion 79 of the movable portion 70B of the seat plate 1B is inserted into the internal space of the fixed portion 70A. At the upper end of the rising portion 79, extending portions 79A, 79B extending outward in the thickness direction of the shutter curtain 1 are formed, and these extending portions 79A, 79B are at the lower end of the inner member 76 of the fixing portion 70A. By moving on the upper surfaces of the formed projecting pieces 76A and 76B, the downward movement limit of the movable portion 70B with respect to the fixed portion 70A is defined.

  In the inside of the fixing portion 70A, a swinging member 81 which is vertically swingable around a fulcrum shaft 80 extending in the width direction of the shutter curtain 1 is accommodated. When the movable portion 70B is raised with respect to the fixed portion 70A as shown in FIG. 14, the swinging member 81 is in contact with the obstacle 34 shown in FIG. When in contact, the extending portion 79A of the rising portion 79 of the movable portion 70B pushes up the projecting piece 81A of the swinging member 81, whereby the swinging member 81 swings upward about the fulcrum shaft 80. The fixed portion 70A and the movable portion 70B constituting the seat plate 1B have lengths extending to the left and right guide rails 6 shown in FIG. 1, and the swinging member 81 also extends to the left and right guide rails 6. It has an extended length.

  The swinging member 81 and the movable portion 70B are formed of, for example, an extrusion-molded article or a pultrusion-molded article made of aluminum alloy or the like. When the lateral width dimension of the inlet / outlet 2 shown in FIG. 1 is large, it is difficult to form the swinging member 81 and the movable portion 70B respectively by one continuous extrusion molded article or pultrusion molded article The rocking member 81 and the movable portion 70B are formed by a plurality of extrusion molded products or pultrusion molded products arranged in the length direction (the width direction of the shutter curtain 1).

For this reason, during the closing movement of the shutter curtain 1, the movable portion 70B of the seat plate 1B abuts against the obstacle 34 existing on the lower side, which is the closing movement direction, as described in FIG. When the extending portion 79A of the movable portion 70B swings the swinging member 81 upward about the fulcrum shaft 80, as shown in FIG. 15, the pressing member 91 presses the protrusion 62B. The second lever member 62 pivots upward about the fulcrum shaft 63. As a result, the friction member 68 attached to the second lever member 62 pushes the portion 36A of the locking wire 36 between the roller 58 and the roller 59 upward.

  By this push-up, the upper first lever member 61 pivots upward about the fulcrum shaft 63 via the friction member 67 attached to the first lever member 61, and this upward pivoting Since the torsion coil spring 64 is compressed by this, the portion 36A of the lock wire 36 between the roller 58 and the roller 59 is clamped with a large load from above and below by the friction members 67 and 68 of the two lever members 61 and 62. By this clamping, the portion 36A of the lock wire 36 is locked, and the lock causes the shutter curtain 1 and the lock wire 36 to be mechanically coupled by the mechanical coupling device 39. Become.

  As shown in FIG. 13, when the movable portion 70B of the seat plate 1B reaches the lowermost position with respect to the fixed portion 70A, the projecting piece 81A of the swinging member 81 extends the movable portion 70B. The downward swing of the swinging member 81 around the fulcrum shaft 80 is restricted by hitting the portion 79A.

  As described above, when the shutter curtain 1 in closing movement abuts against the obstacle 34, the friction members 67 and 68 of the two lever members 61 and 62 cause the portion 36A of the lock wire 36 to be heavily loaded. In order to be locked, before the shutter curtain 1 abuts against the obstacle 34, in other words, when the movable portion 70B of the seat plate 1B reaches the lowermost position with respect to the fixed portion 70A, It is important that the mechanical coupling device 39 be disposed at an appropriate vertical position with respect to the pressing member 91 of the swinging member 81. Arranging the mechanical coupling device 39 at an appropriate vertical position with respect to the pressing member 91 of the swinging member 81 corresponds to the mechanical type when the mechanical coupling device 39 is attached to the fixing portion 70A of the seat plate 1B. Attaching the coupling device 39 to the appropriate vertical position of the fixing portion 70A. In the present embodiment, a device is provided in which the mechanical coupling device 39 can be attached to an appropriate vertical position of the fixing portion 70A.

  Next, this device will be described. As shown in FIG. 4, projecting side portions 55D are formed on both side portions of the case 55 of the mechanical connecting device 39, and the mechanical connecting device 39 is a seat by utilizing these projecting side portions 55D. It is attached to the fixing portion 70A of the plate 1B. Since the attachment structure using these projecting pieces 55D is the same, the attaching structure of one projecting piece 55D will be described with reference to FIG.

  A base member 92 is coupled to the inner upper surface of the fixing portion 70A by a fastening tool 93 such as a rivet, and the base member 92 is formed on the above-described inner and outer members 75 and 76 forming the fixing portion 70A A screw shaft member 95 which protrudes through the holes 94A and 94B to the upper side of the fixed portion 70A is provided. After inserting one or a plurality of washers 96 into the screw shaft member 95, the screw shaft member 95 is inserted into the hole 55E of the projecting portion 55D. By changing the number of washers 96 inserted into the screw shaft member 95 or not inserting the washer 96 into the screw shaft member 95, the vertical arrangement position of the mechanical coupling device 39 in the fixed portion 70A is adjusted. Become. As a result, the arrangement position of the mechanical coupling device 39 can be set to a suitable vertical position with respect to the pressing member 91 of the swinging member 81.

  In order to be able to confirm whether or not the mechanical coupling device 39 is disposed at an appropriate vertical position with respect to the pressing member 91 of the swinging member 81 as shown in FIG. In the front portion 55C of the case 55 of the mechanical coupling device 39, a window hole 55F is formed. The friction member 68 of the lower second lever member 62 and the locking wire 36 when the movable portion 70B of the seat plate 1B reaches the lowermost position with respect to the fixed portion 70A from the window hole 55F. The vertical distance between the portion 36A and the portion 36A described above can be checked, and when the vertical distance becomes a value within a predetermined suitable range, the nut 97 shown in FIG. The screw shaft member 95 is screwed and tightened. Thereby, the mechanical coupling device 39 is fixed to the fixing portion 70A of the seat plate 1B. Then, the window hole 55F is shielded by a shielding member such as a tape to prevent dust and the like from entering the inside of the case 55.

  As a result, the mechanical coupling device 39 is attached to the appropriate vertical position of the fixing portion 70A, and as a result, when the shutter curtain 1 in the closing movement abuts against the obstacle 34, the mechanical coupling device 39 is mechanically coupled. The friction members 67, 68 of the two lever members 61, 62 provided in the device 39 make it possible to lock the portion 36A of the locking wire 36 with a large load.

  The structure for setting the arrangement position of the mechanical coupling device 39 to the position in the vertical direction appropriate for the pressing member 91 of the swinging member 81 as described above is not limited to the structure according to the above method.

  FIG. 10 shows a structure according to another method. In the structure of FIG. 10, a nut 98 is used in place of the washer 96 of FIG. Since the nut 98 is moved up and down little by little along the screw shaft member 95 by rotating, the arrangement position of the mechanical coupling device 39 is a pressing member 91 of the swinging member 81 by the height position of the nut 98. The height position of the mechanical coupling device 39 in the fixed portion 70A can also be finely adjusted.

  The nut 98 may be one. However, in FIG. 10, two nuts 98A and 98B are used, and these nuts 98A and 98B can press one nut against the other nut, and the height of the nuts 98A and 98B in the screw shaft member 95 can be increased. It is a double nut that can fix the height position. Therefore, the arrangement position of the mechanical coupling device 39 can be fixed more reliably.

  As described above, the work for attaching the mechanical coupling device 39 to the fixing portion 70A of the seat plate 1B is the shutter curtain 1 of the shutter device before the repair according to the present embodiment before the repair according to the present embodiment. After the shutter device is installed in the building shown in FIG. 1, it can be opened and closed vertically along the guide rails 6 attached to the left and right buildings 3 of the building. That is, the installation operation of the shutter device itself excluding the above-mentioned mechanical obstacle detection device 35 described in FIG. 4 is performed first, and thereafter, the installation operation of the mechanical obstacle detection device 35 is performed. The installation operation of the mechanical obstacle detection device 35 includes the operation of attaching the unit structure 45 described above to the bobbin 16 and the operation of attaching the mechanical coupling device 39 to the fixing portion 70A of the seat plate 1B. Either of the operation of attaching the unit structure 45 to the bobbin 16 and the operation of attaching the mechanical coupling device 39 to the fixing portion 70A of the seat plate 1B may be performed first, and these operations may be performed simultaneously ( It may be performed to the case where it can be said that it is substantially simultaneous.

  When the mechanical obstacle detection device 35 is installed as described above, the opening 90 etc. for disposing and attaching the mechanical coupling device 39 to the fixing portion 70A of the seat plate 1B in advance It is preferable to form in the factory.

  In the shutter device before repair according to the present embodiment, as described above, the mechanical obstacle detection device including the lock wire 36, the first processing device 37, the second processing device 38, and the mechanical coupling device 39. Since the unit 35 is unitized, the mechanical obstacle detection device 35 transported from the factory to the building where the shutter device according to the present embodiment is installed can be easily installed. The first processing unit 37 and the second processing unit 38 form a unit structure 45, and the first processing unit 37 and the second processing unit 38 alone are unitized. The operation of attaching the second processing device 38 to the tanning 16 can also be easily performed.

  As described above, by attaching the mechanical coupling device 39 to the fixing portion 70A of the seat plate 1B, the first processing device 37 and the second processing device 38 of FIG. The lock wire 36, the ends of which are connected to each other, is bridged between the lint 16 and the shutter curtain 1. Further, since the lock wire 36 is folded back by the mechanical coupling device 39, as shown in FIG. 1, the first portion 36B extending from the lint 16 to the shutter curtain 1 and the shutter curtain 1 And U-shaped with a second portion 36C extending from the fork to the forehead 16. The portion 36A of the locking wire 36 shown in FIGS. 6 and 15, which corresponds to the mechanical coupling device 39, is a folded portion of the U-shaped locking wire 36.

  When the shutter curtain 1 is closed and moved by its own weight, the lock wire 36 rotates the reel 40 of the first processing device by the weight of the shutter curtain 1 and is fed from the reel 40, thereby The length of each of the one portion 36B and the second portion 36C is increased. Further, when the shutter curtain 1 is moved upward by the rotation of the drive shaft 14 of the opening / closing machine 13 described above, the lock wire 36 is loosened, so the return force of the return spring 41 mentioned above is opposite to the above. The locking wire 36 is wound up by the reel 40 rotating in the direction, thereby shortening the respective lengths of the first portion 36B and the second portion 36C. For this reason, the lock wire 36 follows the opening and closing movement of the shutter curtain 1.

In the shutter device before repair according to the present embodiment, as can be seen from FIG. 1, the unit structure 45 composed of the mechanical coupling device 39, the first processing device 37 and the second processing device 38 has a width of the shutter curtain 1 The mechanical coupling device 39 and the unit structure 45 which are not disposed at the central position B in the direction but constitute the above-mentioned mechanical obstacle detection device 35 are the width direction of the shutter curtain 1 from the central position B. Is disposed at a position displaced to one side of the The displaced position is a position on the side where the above-described open / close device 13 serving as a drive device for driving the shutter curtain 1 is disposed.
Further, as shown in FIG. 1, the extending direction of the first portion 36B and the second portion 36C of the locking wire 36 is the vertical direction along the curtain main body 1A of the shutter curtain 1 (substantially vertical direction And the first portion 36B and the second portion 36C are parallel to each other (including substantially parallel to each other).

  Further, as shown in FIGS. 2 and 4, the first portion 36 B and the second portion 36 C of the lock wire 36 are disposed at an inner position of the slit 17 for hanging the shutter curtain in the lint 16. Therefore, the first portion 36B and the second portion 36C do not interfere with the lint 16. In other words, in the first processing device 37 and the second processing device 38 disposed on the upper surface of the fry 16, the position of the portion where the first portion 36B and the second portion 36C of the locking wire 36 hang down is the fancy 16. Is disposed on the lower portion 16 so as to be above the internal position of the slit 17 for hanging the shutter curtain in the above.

  Furthermore, as shown in FIG. 13, the arrangement position of the mechanical coupling device 39 in the fixing portion 70A of the seat plate 1B is not the central position in the thickness direction of the shutter curtain 1 but the thickness of the shutter curtain 1 from this central position. It is a position displaced to one side in the longitudinal direction. Therefore, the locking wire 36 is rephrased at a position where the shutter curtain 1 does not interfere with the above-described curtain main body 1A, as shown in FIG. 8 for both the first portion 36B and the second portion 36C. And, it is disposed at a position away from the curtain main body 1A in the thickness direction of the shutter curtain 1. That is, since the curtain main portion 71A described above is configured of the curtain main body 1A and the fixing portion 70A of the seat plate 1B, both the first portion 36B and the second portion 36C of the lock wire 36 are: It will be arrange | positioned in the thickness direction of the shutter curtain 1 away from the curtain main part 71A (curtain main body 1A) except the fixing | fixed part 70A in which the mechanical coupling apparatus 39 is arrange | positioned.

  The portion of the curtain main portion 71A excluding the fixing portion 70A where the mechanical coupling device 39 is disposed is the curtain main body 1A, and the curtain main body 1A is a large portion which occupies most of the area of the shutter curtain 1. Therefore, as described above, both of the first portion 36B and the second portion 36C of the lock wire 36 from the curtain main portion 71A excluding the fixing portion 70A where the mechanical coupling device 39 is disposed Being placed at a position separated in the thickness direction and not interfering with the curtain main portion 71A, the bridge member is a bridging member bridged between the lint 16 and the shutter curtain 1 The lock wire 36, which is a mechanical member in the embodiment, will not inhibit the opening and closing movement of the shutter curtain 1.

  Further, as described above, the movable portion 70B of the seat plate 1B forms the curtain sub-portion 71B, and as shown in FIG. 8, the dimension in the thickness direction of the shutter curtain 1 with respect to this movable portion 70B. Is W1. Moreover, the thickness direction dimension of the shutter curtain 1 about the fixing | fixed part 70A of the seat plate 1B which comprises a part of curtain main part 71A mentioned above is W2, This W2 is smaller than W1. The lock wire 36 is disposed within the range of W1 and within the range of W2. Since the movable portion 70B forms the curtain sub-portion 71B, the lock wire 36 is disposed within the shutter curtain thickness direction dimension W1 of the curtain sub-portion 71B, and W1 Since the lock wire 36 is also a dimension that defines the overall thickness dimension of the shutter curtain 1, the lock wire 36 is disposed within the overall thickness dimension of the shutter curtain 1.

  Therefore, the lock wire 36 is disposed along the curtain body 1A of the shutter curtain 1, and thereby, the first portion 36B and the second portion 36C of the lock wire 36 are disposed at a position not to interfere with the curtain body 1A. Also, it is possible to suppress an increase in the overall thickness dimension of the shutter curtain 1 including the lock wire 36.

  In addition, when it is assumed that W1 is equal to W2 (including a case where there is a slight difference and it can be said that they are substantially equal), the entire thickness of the shutter curtain 1 including the lock wire 36 It is possible to suppress an increase in height dimension.

  Further, in the shutter device before repair according to the present embodiment, as described with reference to FIG. 4, the arrangement positions of the first processing device 37 and the second processing device 38 in the lint 16 are shutter curtains by the long holes 47 and 50. Since it is adjustable in the thickness direction of 1, the curtain main portion excluding the fixing portion 70A in which the mechanical coupling device 39 is disposed in both the first portion 36B and the second portion 36C of the locking wire 36 It can be arranged more reliably at a position away from 71 A in the thickness direction of the shutter curtain 1. Also. By adjusting the arrangement positions of the first processing device 37 and the second processing device 38 in the lint 16 separately for the first processing device 37 and the second processing device 38, the first portion 36B and the second portion 36C It is also possible to separate the curtain main portion 71A by the same distance in the thickness direction of the shutter curtain 1 except for the fixing portion 70A where the mechanical coupling device 39 is disposed.

  FIG. 16 shows the internal structure of the second processor 38. As shown in FIG. As described above, the second processing device 38 is provided with the turning member 42 in which the end of the locking wire 36 is coupled via the coil spring 43. The pivoting direction of the pivoting member 42 is the vertical direction around the horizontal central axis 42A. In addition, behind the pivoting member 42, a return spring 100 such as a mainspring spring is disposed. The return force of the return spring 100 turns so as to turn the turning member 42 in the C direction, that is, to turn the turning member 42 in the direction to pull up the second portion 36C of the lock wire 36. It acts on the moving member 42. An arc-shaped long hole 42B centered on the central axis 42A is formed in the turning member 42, and the stop member 101 attached to the machine frame 49 of the second processing device 38 is inserted into the long hole 42B. The rotation amount of the rotation member 42 is regulated to a fixed amount by the stop member 101.

  The gear teeth 42C are formed on a part of the outer peripheral portion of the pivoting member 42. Therefore, the pivoting member 42 is a sector gear in which the gear teeth 42C are formed on a part thereof. The gear teeth 42C are provided on the side in the thickness direction of the shutter curtain 1 in the pivoting member 42 (including those that can be said to be substantially the side in the thickness direction; the same applies hereinafter). Further, two rotary dampers 102 are disposed in the second processing device 38, and these dampers 102 are provided with a pinion gear 103 that meshes with the gear teeth 42C of the rotating member 42. A plurality of blades disposed inside the damper 102 are attached to the rotation center shaft 104 of the pinion gear 103 via a one-way clutch, and the pinion gear 103 and the center axis are rotated by rotating the rotation member 42 in the C direction. When the 104 rotates in the E direction, the blades rotate in the viscous fluid filled in the inside of the damper 102 through the one-way clutch. For this reason, the rotating member 42 is rotated at low speed in the C direction by the resistance force of the viscous fluid. On the other hand, when the rotation member 42 rotates in the D direction opposite to the C direction and the pinion gear 103 and the central shaft 104 rotate in the F direction, the rotation in this direction is caused by the disconnecting action of the one-way clutch. Not transmitted to the blade. Therefore, the pivoting member 42 can pivot at high speed in the D direction.

  The number of dampers 102 may be one. However, by making the number of dampers 102 plural as in the present embodiment, it is possible to increase the above-mentioned resistance force for rotating the rotating member 42 in the C direction at a low speed. The speed in the direction can be reduced to the desired speed.

  Further, by setting the rotation member 42 to be a sector gear in which the gear teeth 42C are formed in part, the rotation member 42 is a rotation member as compared to the case in which the gear teeth are formed on the entire circumference. The overall upper and lower dimensions of can be reduced. As a result, the upper and lower dimensions of the second processing unit 38 can be reduced, which in turn makes it possible to reduce the upper and lower dimensions of the above-described unit structure 45 configured by the first processing unit 37 and the second processing unit 38. As shown, the unit structure 45 can be effectively arranged in the space with a small vertical dimension between the lint 16 and the aforementioned shutter box 8.

  Furthermore, the rotating member 42 is a sector gear in which the gear teeth 42C are formed in part, and the gear teeth 42C are provided on the side of the rotating member 42 in the thickness direction of the shutter curtain 1 as described above. Since the arrangement position of the rotation member 42 in the second processing device 38 can be set to a high position, the shutter curtain 1 is opened to the fully open position without the rotation member 42 interfering with the seat plate 1B. You will be able to move it.

  Further, the gear teeth 42C are formed on the side opposite to the shutter curtain 1 side of the pivoting member 42, and on the same side as the shutter curtain 1 in the pivoting member 42, there is a recess 42D in which the gear teeth 42C are not formed. Since it is formed, this also prevents the pivoting member 42 from interfering with the seat plate 1B when the shutter curtain 1 is fully opened, and when the shutter curtain 1 is moving in the opening and closing directions, The moving member 42 can be prevented from interfering with the curtain body 1A.

  Further, in the present embodiment, as shown in FIG. 4, the connecting portion N1 of the coil spring 43 and the second portion 36C of the lock wire 36 is a connecting portion N2 of the rotating member 42 and the coil spring 43. Against the shutter curtain 1 side. Therefore, even if the shutter curtain 1 reaches the fully open position, the coil spring 43 can be prevented from coming into contact with the slat forming the curtain body 1A, and the coil spring 43 can be rotated by the rotating member 42 and the coil spring. Since it is possible to suppress swinging to the side of the shutter curtain 1 around the connecting portion N2 with 43, it is possible to prevent the coil spring 43 from coming into contact with the slat forming the curtain body 1A by this suppression.

  Further, as shown in FIG. 16, a micro switch 170 which is a contact type switch means is fixedly disposed on the upper portion of the machine frame 49 of the second processing device 38. The micro switch 170 is provided with an actuating member (actuator) 171 which is urged by a spring in a direction to project from the micro switch 170, and the micro switch 170 is a second treatment disposed in the lint 16. The actuating member 171 is fixedly arranged on the machine frame 49 of the device 38 so as to project downward. The lead wire 172 of the micro switch 170 is connected to the control device 27 described above. On the other hand, a dog member 173 is attached to an outer peripheral surface 42D of a portion where the gear tooth 42C is not formed in the rotation member 42.

  The actuating member 171 of the micro switch 170 is in contact with the outer peripheral surface 42D of the pivoting member 42 unless the shutter curtain 1 in the closing movement abuts on an obstacle. On the other hand, when the shutter curtain 1 in the closing movement abuts against the obstacle and the pivoting member 42 pivots in the direction D by the operation of the mechanical coupling device 39, the actuating member 171 abuts against the dog member 173 It has become.

  For this reason, in the present embodiment, the micro switch 170, which is an electric switch, detects the tension force acting on the lock wire 36 by the actuation of the mechanical coupling device 39 through the pivoting member 42. The lock wire 36 is a tension force acting member. Then, in the present embodiment, when the base plate 1B of the shutter curtain 1 contacts the obstacle 34 shown in FIG. 1 during the closing movement of the shutter curtain 1 by the mechanical obstacle detection device 35 and the micro switch 170. The electric obstacle detection device is an electric obstacle detection means for electrically detecting the obstacle 34.

  As described above, the mechanical coupling device 39 is more effective than the microswitch 170 in the period from the state where the shutter curtain 1 reaches the fully open position until the shutter curtain 1 reaches the fully closed position (in other words, always). It is positioned on the side of the closing movement direction, that is, on the lower side.

  As shown in FIG. 2, the micro switch 170 is closer to the winding shaft 11 side than the central position in the thickness direction (front-rear direction) of the shutter curtain 1 drawn from the winding shaft 11, that is, the micro switch 170 , And the control device 27 side. That is, the micro switch 170 is disposed on the same side as the control device 27 with reference to the central position in the thickness direction of the shutter curtain 1. Therefore, maintenance work such as repair and replacement of the micro switch 170 and the control device 27 is facilitated.

The end of the is extended. The control wires 111 to 113, like the lock wire 36 described above, are flexible string-like members, and are also elongated members.

  Also, these control wires 111 to 113 are slidably inserted into the flexible outer cables 114 to 116. Therefore, the control wires 111 to 113 are protected by the outer cables 114 to 116.

  As shown in FIG. 16, the first control wire 111 extends to the second processing device 38, and the end of the first control wire 111 is a pivoting member 42 of the second processing device 38. It is connected. Further, as shown in FIG. 2, the second processing device 38 is a component of the first control wire 111 and the outer cable 114 into which the first control wire 111 is inserted. Are wired in the ceiling back space 7 in which the above-mentioned unit structure 45 and the opening / closing machine 13 are arranged, and avoid the object 117 existing in the ceiling back space 7, in other words, bypass the object 117 Then, the first control wire 111 and the outer cable 114 are wired in a space where wiring is possible. Note that this space may exist in advance, and when wiring the first control wire 111 and the outer cable 114, a part of the object 117 is cut or a hole is provided in the object 117. , May be formed.

  The wiring of the first control wire 111 and the outer cable 114 without interference with the object 117 is possible because the first control wire 111 and the outer cable 114 have flexibility. is there.

As a result, the first control wire 111 and the outer cable 114 do not interfere with the connecting member 26 which connects the tanning member 16A of the twill 16 and the shutter box 8 shown in FIG. There is.

  From the above, in the shutter device before repair according to the present embodiment, the lock wire 36 extending from the mechanical coupling device 39 in the opening movement direction of the shutter curtain 1 is an intermediate device (in other words, relay device) It is connected to the automatic closing device 32 via a second processing device 38 and a first control wire 111.

  As shown in FIG. 17 and FIG. 18, the machine frame 110 of the automatic closing device 32 is provided with two rising portions 110B and 110C facing each other, and these rising portions 110B and 110C are formed A plate-like slide member 120 having a length straddling the two rising portions 110B and 110C is slidably inserted into the holes 110D and 110E. A spring 121 is wound around the outer periphery of the slide member 120, and due to the spring force of the spring 121, a forward force toward the rising portion 110B always acts on the slide member 120. The direction of the forward force is a direction to move the first portion 31A of the above-described lever member 31 provided in the opening / closing machine 13 described in FIG. 3 in the A direction.

And a spring 132 for biasing the bending lever member 129 in the G direction about the central axis 129A, and the spring force of these springs 128, 131, 132 makes the roller 130 in a normal state. As shown in FIG. 18, the recess 120B is fitted in the recess 120B, and by this fitting, the advance of the slide member 120 by the spring 121 described above is stopped. The position of the front end of the slide member 120 when the forward movement is stopped by the roller 130 fitted to the concave portion 120B in this manner is the H position among the three positions H, I, and J shown in FIG.

  As shown in FIG. 18, in the automatic closing device 32, a micro switch 135 is disposed, and the micro switch 135 is provided with an operating member 136 biased in a direction to project from the micro switch 135 by a spring It is done. Further, a dog member 137 is attached to the slide member 120 at a portion opposite to the concave portion 120B, and the actuating member 136 is in contact with the dog member 137.

  The slide member 120 is connected to the connection member 138 provided with the first connection portion 138A and the second connection portion 138B, and the connection member 140 is connected to the tip of the plunger 127 of the solenoid 126, as described above. One end of the spring 132 is connected to the connecting member 140. The other end of the aforementioned first control wire 111 whose one end is connected to the pivoting member 42 of the second processing apparatus 38 shown in FIG. 4 is the first end of the connecting member 138 of the slide member 120. The end of the second control wire 112 is connected to the connecting portion 138A, and the end of the second control wire 112 is connected to the connecting member 140 connected to the plunger 127. The end of the third control wire 113 is connected to the connecting member 138 of the slide member 120. It is connected to the 2nd connection part 138B.

  In addition, the second control wire 112 inserted into the inside of the outer cable 115 extends to the operating device 30 shown in FIG. 1 and an end portion of the second control wire 112 protruding from the outer cable 115 A manual operation member such as a lever member disposed in the operation device 30 is connected to the. Furthermore, the third control wire 113 inserted into the inside of the outer cable 116 extends from the above-described under-the-ceiling space 7 in which the automatic closing device 32 is disposed to a manually operable position in the building. In this embodiment, as shown in FIG. 1, this position is the position of the upper part of the entrance 2 passing through the slit 17 of the lint 16 from the ceiling space 7 and protrudes from the outer cable 116 A manual operation member 141 capable of manually pulling and operating the third control wire 113 is coupled to an end portion of the third control wire 113, and the manual operation member 141 is a ring member in the present embodiment. ing.

  In a building where a shutter device before repair according to the present embodiment is installed, when a disaster such as a fire occurs while the shutter curtain 1 is fully open, control is performed by inputting a signal from a sensor that detects this disaster. The device 27 energizes the solenoid 126 of the automatic closing device 32 to energize the solenoid 126 so that the plunger 127 of the solenoid 126 retracts against the spring force of the spring 128. As a result, the bending lever member 129 rotates in the direction opposite to the G direction in FIG. 18 about the central axis 129A against the spring force of the springs 131 and 132. The state at this time is shown in FIG. When the bending lever member 129 rotates in the direction opposite to the G direction about the central axis 129 A, the roller 130 of the bending lever member 129 escapes from the recess 120 B of the slide member 120, so the spring force of the spring 121 of the slide member 120 The forward movement is stopped by the front end of the connection member 138 abutting the aforementioned rising portion 110B of the machine frame 110 of the automatic closing device 32. The position of the front end of the slide member 120 at this time is the I position which is the foremost position as shown in FIG. 19 among the three positions H, I and J shown in FIG.

  In addition, when the slide member 120 is advanced, the actuating member 136 of the micro switch 135 is disengaged from the position of the dog member 137 attached to the slide member 120, so that the micro In response to the signal from the switch 135, the controller 27 stops the energization of the solenoid 126.

  When the energization of the solenoid 126 is stopped, the plunger 127 is protruded from the solenoid 126 by the spring force of the spring 128, and the bending lever member 129 is in the direction of G in FIG. Turn to Since the slide member 120 at this time is advanced to the movement limit where the front end of the slide member 120 reaches the I position, the roller 130 of the bending lever member 129 slides as shown in FIG. It strikes the aforementioned inclined surface 120C of the member 120. Therefore, the protruding movement of the plunger 127 and the rotation of the bending lever member 129 in the G direction about the central axis 129A are stopped halfway.

  As described above, when the slide member 120 of the automatic closing device 32 advances, the actuating member 122 provided at the front end of the slide member 120 is moved through the open / close machine 13 via the actuated member 123 shown in FIG. In order to press the first portion 31A of the lever member 31 in the A direction of FIG. 3, as described above, the first portion 31A pivots in the A direction with the second bent portion 31D of the lever member 31 as a fulcrum. Thus, the brake shaft 21 and the brake drum 22 of the brake device 19 of the opening and closing machine 13 slide in the A 'direction which is the same direction as the A direction, whereby the brake device 19 which has been on until then is turned off. Become. For this reason, the shutter curtain 1 which has been fully opened is closed and moved downward while the winding shaft 11 described above is rotated by the weight of the seat plate 1B and the like in the lower part of the winding shaft 11. The aforementioned drive shaft 14 of the opening / closing machine 13 also freely rotates via the driving force transmitting means 12 and the shutter curtain 1 is fully closed, whereby a disaster prevention section by the shutter curtain 1 is formed.

  Also, when a person finds that a disaster such as a fire has occurred, this person is disposed in the operation device 30 shown in FIG. 1 and connected to the end of the second control wire 112 described above. The second control wire 112 is pulled and operated by a manual operation member such as a lever member. As a result, the plunger 127 of the solenoid 126 retracts, so even before the solenoid 126 is energized and excited, the bending lever member 129 is centered on the central axis 129A as in the case where the solenoid 126 is energized and excited. In order to rotate in the direction opposite to the G direction in FIG. 18, the roller 130 of the bending lever member 129 escapes from the recess 120 B of the slide member 120, and the slide member 120 is advanced by the spring force of the spring 121.

  For this reason, according to the present embodiment, even in the manual operation using the second control wire 112, the brake device 19 of the open / close machine 13 is turned off, and the shutter curtain 1 which is fully open is closed and moved completely. be able to.

  Thus, in the present embodiment, the manual control member such as the second control wire and the lever member connected to the end of the second control wire 112 is manually operated when a disaster such as a fire occurs. The shutter curtain 1 that has been fully opened is configured to be a manual closing device for closing movement (closing operation).

  And in this embodiment, as FIG. 1 shows, the operating device 30 is one of the building housings 3 of a right-and-left wall etc. in the position close | similar to the opening / closing machine 13 and the automatic closing apparatus 32. Being disposed in the building frame 3A, the length of the second control wire 112 which is bridged between the automatic closing device 32 and the operating device 30 can be shortened. Therefore, the automatic closing device 32 instantly pulls the pulling force when the second control wire 112 is pulled by the manual operation member such as the lever member as compared to the case where the operation device 30 is disposed in the other building frame 3 The closing movement of the shutter curtain 1 can be quickly started.

  When the shutter curtain 1 reaches the fully closed position and a disaster such as a fire is eliminated, the end of the third control wire 113 described above is pulled by the operation of the manual operation member 141 shown in FIG. Thus, since the third control wire 113 is connected to the slide member 120 of the automatic closing device 32, the slide member 120 is retracted against the spring force of the spring 121. Therefore, the slide member 120 returns from the position shown in FIG. 20 to the initial position where the front end becomes the H position in FIG. Further, when the slide member 120 returns to this initial position, the bending lever member 129 rotates in the G direction in FIG. 18 by the spring force of the springs 131 and 132 about the central axis 129A. The roller 130 is fitted in the recess 120B of the slide member 120 as shown in FIG. 18, and the slide member 120 stops when the front end of the slide member 120 reaches the H position. Thereby, the automatic closing device 32 returns to the initial state before a disaster such as a fire occurs.

  In addition, when the slide member 120 returns to the initial position, the brake shaft 21 and the brake drum 22 of the brake device 19 of the opening / closing device 13 move in the direction opposite to the A 'direction by the spring 23 described above in FIG. 19 returns to on. Thereafter, the shutter curtain 1 is opened and moved to the fully open position as described above by operating the above-mentioned "open" button provided on the operating device 30.

  In the shutter device before repair according to the present embodiment, the lock wire 36 and the first control wire 111 are the first string-like members, and the automatic closing device 32 is turned on by being pulled. A second control wire 112, which is a second string-like member, for manually turning the brake device 19 off is connected. Further, to the automatic closing device 32, a third control wire 113 which is a third string-like member for returning the automatic closing device 32 to an initial state by being pulled is connected.

  In the case where a connector 36F for forming a loop 36E for connecting the upper end to the coil spring 43 is provided at the upper end of the second portion 36C of the lock wire 36 shown in FIG. It is preferable that the horizontal cross section of the connector 36F has an elongated shape elongated in the thickness direction of the shutter curtain 1 by crushing the connector 36F or the like. According to this, the hole 57 formed in the upper surface portion 55B of the case 55 for housing the mechanical coupling device 39 shown in FIG. 4 and in which the second portion 36C enters and exits is orthogonal to the elongated direction of the coupling tool 36F. Since the long hole is long in the width direction of the shutter curtain 1, the lower surface of the connector 36F is an outer portion of the long hole 57 when the shutter curtain 1 opens and moves to the fully open position as described above. By contacting the upper surface 55B of the case 55, it is possible to prevent the lower surface of the connector 36F from intruding into the inside of the long hole 57 and opening and moving the shutter curtain 1 more than a predetermined amount.

  As described above, the solenoid 126 of the automatic closing device 32 is energized, excited or connected to the end of the second control wire 112 by the control device 27 which receives a signal from a sensor that has detected a disaster such as a fire. When the second control wire 112 is pulled by a manual operation member such as a lever member, the brake device 19 of the open / close unit 13 is turned off and the shutter curtain 1 is moved downward from the fully open position. In other words, when the automatic closing device 32 is in the state shown in FIG. 20, the obstacle 34 shown in FIG. 1 exists below the shutter curtain 1 which is the closing movement direction. In the middle of the closing movement of the shutter curtain 1, the curtain sub-portion 71 disposed at the end of the closing side of the shutter But, in other words, the movable portion 70B of the above-described forming the lower portion of the seat plate 1B of the shutter curtain 1 is in contact with the obstacle 34, the descent of the movable part 70B is stopped.

  Even if the descent of the movable portion 70B is stopped, the above-mentioned curtain main portion 71A, which is composed of the curtain main body 1A and the above-mentioned fixed portion 70A of the seat plate 1B, descends. Due to the relative rise of the curtain sub-portion 71B with respect to the portion 71A, the first lever member 61 and the second lever member 62 of the mechanical coupling device 39 described above in the friction members 67, 68, as described in FIG. The folding portion 36A of the locking wire 36 is sandwiched, and the locking wire 36 is locked by the clamping. As a result, the shutter curtain 1 and the lock wire 36 serving as the bridging member according to the present embodiment are mechanically coupled by the mechanical coupling device 39.

  The lock wire 36 so far is fed from the reel 40 of the first processing device 37 described above following the closing movement of the shutter curtain 1, and the folded portion 36A of the lock wire 36 is a friction member 67, 68. When the lock wire 36 is clamped and locked, the first portion 36B and the second portion 36C of the lock wire 36 are in a state of being folded back at the folded portion 36A due to the dent deformation of the obstacle 34. Since the weight of the portion of the shutter curtain 1 above the curtain subportion 71B, that is, the weight of the curtain main portion 71A acts on the locking wire 36, particularly, the second portion 36C has a large tension force. Works.

  Then, as shown in FIG. 15, the folded portion 36A of the lock wire 36 is sandwiched by the friction members 67 and 68 provided on the first lever member 61 and the second lever member 62 and having a large frictional force, Since the locking member is locked, the sliding movement of the locking wire 36 with respect to the first lever member 61 and the second lever member 62 can be prevented by the friction members 67 and 68. Further, in the present embodiment, the above-mentioned shaft 63 which is the swinging central axis of the first lever member 61 and the second lever member 62 is made common to the first lever member 61 and the second lever member 62. Therefore, the structure of the mechanical coupling device 39 can be simplified by reducing the number of members, and the positional relationship between the friction members 67 and 68 can be appropriately set. Therefore, the above-described folded portion 36A of the locking wire 36 Can be further securely clamped and locked by the friction members 67 and 68.

  Furthermore, the abutment of the shutter curtain 1 against the obstacle 34 is not performed under the position where the mechanical coupling device 39 described above is disposed, and the shutter curtain 1 from the lower side of the disposition position of the mechanical coupling device 39. When the portion of the shutter curtain 1 on which the mechanical coupling device 39 is arranged is to move slightly in the closing direction of the shutter curtain 1, the first processing device 37 The lock wire 36 drawn out from the reel 40 tries to move so as to shift the portion pinched by the friction members 67 and 68 from the first portion 36B side to the second portion 36C side. Since the distance between the friction members 67 and 68 gradually decreases in the direction opposite to the moving direction, the lock wire 36 is used as the first lever member 61 and the second lever member 62. Can be more effectively prevented from sliding move.

  Further, in the present embodiment, when the folded portion 36A of the lock wire 36 is sandwiched and locked by the friction members 67 and 68, as shown in FIG. A non-linear bypass portion 36G is formed by one of the guide members 60A and the second lever member 62. For this reason, even if the obstacle 34 is a hard object that does not dent or hardly dent, it is possible to pull the second portion 36C of the locking wire 36 by forming the bypass portion 36G in the locking wire 36. Thus, a large tension can be exerted on the second portion 36C.

  As described above, the sliding movement of the locking wire 36 with respect to the first lever member 61 and the second lever member 62 is blocked by the friction members 67 and 68, and the second portion 36 C of the locking wire 36 is When a large tension acts, the pivoting member 42 of the second processing device 38 shown in FIG. 16 pivots in the direction D of FIG. The amount of movement corresponds to the length of the circular arc long hole 42B into which the above-described stop member 101 is inserted. In this rotation, the pinion gear 103 of the rotary damper 102 is rotated in the F direction. However, with the rotation of the pinion gear 103 in the F direction, as described above, the damper 102 does not generate a resistance force due to the viscous fluid. For this reason, the rotating member 42 is rotated in the direction D at high speed by the tension applied to the second portion 36C, and the first control wire has one end connected to the rotating member 42. 111 will be pulled.

  The second portion 36C of the lock wire 36 is not directly connected to the pivoting member 42, and an impact load buffering elastic member is formed between the second portion 36C and the pivoting member 42. Since the above-described coil spring 43 is interposed, even if the above-mentioned large tension acts momentarily on the second portion 36C, this tension does not act directly on the turning member 42, and the tension is not exerted. Can be relieved to act on the pivoting member 42.

  Also, when the amount of rotation of the rotation member 42 in the direction D reaches the limit value defined by the stop member 101 inserted in the arc-shaped long hole 42B, the shock load buffering action by the coil spring 43 Thus, it is possible to prevent a large impact load from propagating between the second portion 36C of the lock wire 36 and the pivoting member 42.

  As described above, when the first control wire 111 is pulled, the other end of the first control wire 111 is connected to the slide member 120 shown in FIG. It moves backward while resisting the spring 121. Since the amount by which the first control wire 111 is pulled and the amount by which the slide member 120 is retracted are the amounts defined by the length of the long hole 42B of the rotating member 42 shown in FIG. The slide member 120 which has reached the position I shown in FIG. 20 does not retract to the retraction limit where the position of the front end of the slide member 120 becomes the H position in FIG. Stop at an intermediate position between the H position and the I position. The state at this time is shown in FIG. At this time, the position of the slide member 120 in contact with the roller 130 of the bending lever member 129 moves in the longitudinal direction of the slide member 120 which is the slide direction of the slide member 120, as compared with the case of FIG. The roller 130 is still in contact with the inclined surface 120C described above.

  Further, since the position of the front end of the slide member 120 at this time is retracted from the I position to the J position, the first portion 31A of the lever member 31 of FIGS. 3 and 17 is moved by the actuating member 122 of the slide member 120. The load that has been pressed in the A direction of FIG. 3 is released. For this reason, the brake device 19 of the opening and closing machine 13 is switched from off to on. And since the above-mentioned drive shaft 14 of the opening / closing machine 13 can not be rotated by turning on the brake device 19, the winding shaft 11 to which the upper end of the shutter curtain 1 is coupled can not be rotated either.

  Therefore, the shutter curtain 1 in contact with the obstacle 34 is closed at the contact position and stops moving. This stop is performed by the above-described mechanical coupling device 39 including the first lever member 61 and the second lever member 62 for locking the lock wire 36 with the friction members 67 and 68, or the second process which is also mechanical. The mechanical structure is constituted by the device 38, the slide member 120 which is a member of the mechanically closing automatic closing device 32, the brake device 19 of the opening / closing machine 13 which is turned on mechanically, and the like. For this reason, after the shutter curtain 1 closes and starts moving, the building in which the shutter device according to the present embodiment is installed is subjected to a power failure due to the occurrence of a disaster such as a fire or due to other reasons. Also, the shutter curtain 1 that has been in contact with the obstacle 34 can be stopped during the closing movement.

  Further, in the present embodiment, as described with reference to FIG. 1, the mechanical coupling device 39 and the unit structure 45 constituting the mechanical obstacle detection device 35 described above have a central position in the width direction of the shutter curtain 1. It is not disposed at B, and is disposed at a position displaced from the central position B to one side in the width direction of the shutter curtain 1 at which the opening / closing device 13 and the automatic closing device 32 are disposed. . Therefore, the length of the first control wire 111 wired between the second processing device 38 and the automatic closing device 32 can be shortened. Therefore, when the shutter curtain 1 in the closing movement abuts against the obstacle 34, the above-mentioned tension force acting on the first control wire 111 can be instantaneously input to the automatic closing device 32, thereby opening and closing. The braking device 19 of the machine 13 can be turned on quickly.

  As described above, in the shutter device before repair according to the present embodiment, the mechanical coupling device 39 includes the first and second lever members 61, which are a pair of clamping members disposed on the shutter curtain 1, 62 by clamping the lock wire 36, which is a string-like member, by the pair of first and second lever members 61, 62 when the shutter curtain 1 in closing movement abuts against the obstacle 34, A tension acts on the lock wire 36 to slide the slide member 120 to turn on the brake device 19.

  In addition, for example, there is not enough space for wiring the first control wire 111 at the location due to the presence of a large object between the unit structure 45 and the automatic closing device 32, etc. Therefore, the unit structure If it is impossible or difficult to wire the first control wire 111 with a shortened length between the second processing device 38 of the object 45 and the automatic closing device 32, the unit structure in the lint 16 The position where the object 45 is arranged is changed from the above position, whereby the space for wiring the first control wire 111 and the first control wire 111 between the second processing device 38 and the automatic closing device 32. You may make it wire by passing through. As a result, the opening / closing machine 13 and the automatic closing device 32 are disposed in the width direction of the shutter curtain 1 from the central position B in the width direction of the shutter The position of the mechanical obstacle detection device 35 described above, which is composed of the unit structure 45 and the like, is shifted to a position opposite to the above-described one side, the central position B of the shutter curtain 1 in the width direction. 1, i.e., a position further away from the center position B than the opening / closing device 13 and the automatic closing device 32.

  As described above, after the shutter curtain 1 in closing movement abuts against the obstacle 34 and the brake device 19 of the opening / closing machine 13 is turned on, when the obstacle 34 is removed, the curtain sub-portion of the shutter curtain 1 is As 71 B descends, clamping and locking of the lock wire 36 by the friction members 67 and 68 of the first lever member 61 and the second lever member 62 of the mechanical coupling device 39 is released, and the shutter by the mechanical coupling device 39 is released. The mechanical connection between the curtain 1 and the locking wire 36 is also released. As a result, the tension of the lock wire 36 disappears, so that the pivoting member 42 of the second processing device 38 to which the return force by the return spring 100 of FIG. 16 is acting is rotated in the C direction of FIG. The slide member 120 of the automatic closing device 32, which has been moved in the backward direction by the first control wire 111, moves from the position J shown in FIG. 21 to the position I shown in FIG. The spring 121 carries out the forward movement to shift. Therefore, the brake device 19 of the opening and closing machine 13 is switched from on to off again, and the shutter curtain 1 is closed and resumes movement.

  Further, when the pivoting member 42 of the second processing device 38 pivots in the C direction in FIG. 16, the pinion gear 103 of the rotary damper 102 rotates in the E direction, and in this E direction, the damper 102 is made of viscous fluid. Resistance is generated. Therefore, the position of the front end of the slide member 120 is shifted from the position J shown in FIG. 21 to the position I shown in FIG. 20, and this transition switches the brake device 19 of the open / close machine 13 from on to off. Due to the delay action of the damper 102, it does not take place instantaneously. Therefore, the shutter curtain 1 closing and resuming movement due to the removal of the obstacle 34 is started with a time delay from the removal of the obstacle 34. Therefore, the task of removing the obstacle 34 takes time. It can be carried out.

  As can be seen in this description, the two rotary dampers 102 disposed in the second processor 38 are delay devices for causing the above-mentioned delay.

  That is, in the shutter device before repair according to the present embodiment, the damper 102 delays the operation of the second processing device 38 which is an intermediate device, that is, the rotation of the rotation member 42 of the second processing device 38. It has become a thing.

  In order to prevent the viscous fluid from falling from the unit structure 45 shown in FIG. 4 even if there is leakage of the viscous fluid from the damper 102 of this delay device, for example, a base member of the unit structure 45 The base member 44 may be shaped like a bowl by providing a rising wall around 44.

  Further, this delay device may adopt mechanical means including, for example, a mainspring type timer instead of the damper 102. According to this mechanical means, unlike the viscous fluid type damper 102, the delay time can be set more accurately without being influenced by the environmental temperature.

  Then, after the shutter curtain 1 is fully closed, the slide member 120 of the automatic closing device 32 has the position of the front end by pulling the third control wire 113 with the manual operation member 141 shown in FIG. In order to perform the return movement back to the H position of FIG. 18, the entire automatic closing device 32 returns to the initial state of FIG.

  Incidentally, by extending the third control wire 113 to the operating device 30 shown in FIG. 1, the end portion of the third control wire 113 is a manual operation member such as a lever member disposed in the operating device 30, or It may be a rotating member that is rotated by a switch-operated electric motor disposed in the operating device 30, and may be connected to a winding member for winding the third control wire 113 freely. Thereby, the third control wire 113 may be pulled by the manual operation member or the winding member rotated by the electric motor.

  In the embodiment described above, as described above, both the first portion 36B and the second portion 36C of the lock wire 36 exclude the curtain main portion 71A excluding the fixing portion 70A in which the mechanical coupling device 39 is disposed. The shutter curtain 1 is disposed at a position distant in the thickness direction of the shutter curtain 1 and does not interfere with the curtain main portion 71A, so it is a bridging member bridged between the lint 16 and the shutter curtain 1 The lock wire 36, which is a mechanical member in the present embodiment, does not inhibit the opening and closing movement when the shutter curtain 1 is moving in the opening and closing direction, and the opening and closing movement is performed smoothly. Can.

  Further, in the present embodiment, the lock wire 36 is separated from the curtain main portion 71A except the fixing portion 70A of the shutter curtain 1 for both the first portion 36B and the second portion 36C. Even if it moves, the entire lock wire 36 does not rub against the curtain main portion 71A except the fixing portion 70A. Therefore, the entire lock wire 36 and the curtain main portion 71A excluding the fixing portion 70A But can prevent damage.

  Further, according to the present embodiment, as described in FIG. 2, the shutter curtain 1 is suspended to the lower side of the ceiling member 5 through the slits 17 of the lint 16 disposed in the ceiling member 5 and the locking wire 36 The first and second portions 36B and 36C have a length straddling the upper and lower sides of the ceiling member 5, and the first and second portions 36B and 36C do not contact the lint 16, and Since the slit 17 is inserted into the slit 17, the smooth movement of the locking wire 36 with respect to the lint 16 can be ensured when the shutter curtain 1 is moving in the opening and closing direction.

  Furthermore, since the first and second portions 36B and 36C of the locking wire 36 do not interfere with the tanning 16, damage to both the locking wire 36 and the tanning 16 can be prevented.

  The above description is an explanation of the operation of the shutter device in the case where the shutter device before repair according to the present embodiment functions as a shutter device for disaster prevention.

  Next, an operation of the shutter device in the case where the shutter device before the repair according to the present embodiment functions as a management shutter device will be described.

  In order to close and move the shutter curtain 1 which is fully open at the normal time, the shutter curtain 1 is moved by electric operation by operating the “close” button of the operating device 30 shown in FIG. On the other hand, in order to open and move the shutter curtain 1 which is fully closed, the shutter curtain 1 is opened and moved electrically by operating the “open” button of the operation device 30. As described above, when the shutter device before repair according to the present embodiment operates as a management (for opening) shutter device for opening and closing the entrance 2, the closing movement of the shutter curtain 1 is the operation device 30. Is operated by the operation of the “close” button, and the second operation is performed by the operation of the automatic closing device 32 described above or a manual operation member such as a lever member connected to the end of the second control wire 112 described above. It is not performed by pulling operation of the control wire 112 or the like. Therefore, the state of the automatic closing device 32 when the shutter curtain 1 is closed and the movement is started at the normal time (in other words, normal time) is the state shown in FIG. 17 and FIG.

  When the shutter curtain 1 in the closing movement abuts against the obstacle 34, the first lever member 61 and the second lever member 62 of the mechanical coupling device 39 are friction members 67 as in the above-described emergency. , 68, downward tension is applied to the second portion 36C of the lock wire 36 in order to clamp and lock the portion 36A of the lock wire 36.

  As a result, the closing movement of the shutter curtain 1 is stopped by the tension acting on the second portion 36C of the locking wire 36. Further, as a result, the pivoting member 42 of the second processing apparatus 38, in which the end of the second portion 36C of the locking wire 36 is coupled via the coil spring 43, pivots in the direction D shown in FIG. It will be. As described above, the other end of the first control wire 111 whose one end is connected to the pivoting member 42 is connected to the first connecting portion 138A of the connecting member 138 of the slide member 120. Therefore (see FIG. 18), the first control wire 111 is pulled by rotating the rotating member 42 in the D direction. As shown in FIG. 18, a gap 176 is formed between the rear end 120 E of the wide portion 120 D of the slide member 120 before the first control wire 111 is pulled and the roller 130 of the bending lever member 129. Is formed. For this reason, when the first control wire 111 is pulled, the slide member 120 can be retracted by the gap 176. As described above, the pivoting amount of the pivoting member 42 corresponds to the length of the arc-shaped elongated hole 42B into which the stop member 101 is inserted, and the retraction distance (movement amount) of the slide member 120 Is substantially the same as the amount of rotation of the rotation member 42. Therefore, the backward movement of the slide member 120 is stopped immediately after the rear end portion 120E of the wide portion 120D abuts on the roller 130. Therefore, there is almost no force for the slide member 120 to press the roller 130, and there is no possibility that the roller 130 is damaged by the retraction of the slide member 120.

  As described above, FIG. 16 is a view showing the second processing unit 38 when the shutter curtain 1 is not in contact with the obstacle 34. At this time, the second processing unit 38 is mounted on the upper portion of the machine frame 49 of the second processing unit 38. The actuating member 171 of the microswitch 170 fixedly arranged is in contact with the outer peripheral surface 42D of the rotating member 42, that is, the microswitch 170 is not in operation. On the other hand, FIG. 22 is a view showing the second processing device 38 when the pivoting member 42 is pivoted in the D direction by the shutter curtain 1 coming into contact with the obstacle 34. As shown in FIG. 22, when the pivoting member 42 pivots in the D direction, the actuating member 171 of the micro switch 170 abuts against the dog member 173 attached to the pivoting member 42 ( Get up). Therefore, the actuating member 171 projecting downward due to the biasing force of the spring is retracted, and the micro switch 170 is in the actuated state. That is, it is in a state where it is detected that tension acts on the second portion 36C of the lock wire 36, in other words, a state where the obstacle 34 is electrically detected.

  Therefore, as described above, the shutter curtain 1 according to the present embodiment includes the mechanical obstacle detection device 35 and the micro switch 170 in addition to the mechanical obstacle detection device 35 as described above. An electric obstacle detection device is provided which electrically detects an obstacle 34 during the motor-operated closing movement. That is, the electric obstacle detection device 174 serves as a normal obstacle detection means for detecting the contact with the obstacle 34 during the motorized descent of the shutter curtain 1 at the normal time. On the other hand, the mechanical obstacle detection device 35 serves as an emergency obstacle detection means for detecting the contact of the shutter curtain 1 with the obstacle 34 during the fall of its own weight in an emergency. Further, the micro switch 170 is a tension detection means for detecting that tension is applied to the lock wire 36 which is a tension application member.

  The micro switch 170 operates so that the closing movement of the shutter curtain 1 is stopped by the mechanical shutter curtain stop device after the closing movement of the shutter curtain 1 abuts against the obstacle 34. It has become.

  The micro switch 170 is not disposed at the central position B in the width direction (left-right direction) of the shutter curtain 1 shown in FIG. 1, and is displaced from the central position B to one side in the width direction of the shutter curtain 1. , That is, at the position where the open / close machine 13 is disposed.

  When the micro switch 170 operates, an obstacle detection signal indicating that the obstacle 34 has been detected is input to the control device 27 (not shown) to which the lead wire 172 of the micro switch 170 is connected. Thereby, the following control is performed by the control device 27 for avoiding contact (collision) with the obstacle 34 in contact with the shutter curtain 1.

  First, control is performed to shut off the energization of the coil 25 of the electric motor device 18 of the opening / closing machine 13, whereby the positive drive of the electric motor device 18 is stopped. Thereafter, control is performed to cut off the energization of the solenoid 24 of the brake device 19 of the opening / closing machine 13, whereby the brake device 19 is turned on. As a result, the shutter curtain 1 stops the motorized descent.

  Thereafter, control is performed to energize the solenoid 24 of the brake device of the opening and closing machine 13 and control is performed to energize the coil 25 of the electric motor device 18 of the opening and closing machine 13 again. Thereby, the electric motor device 18 is reversely driven (reverse rotation). As a result, the shutter curtain 1 is electrically raised (opened), in other words, reversely raised.

  Control for interrupting energization of the coil 25 of the electric motor device 18 of the opening / closing device 13 (when reverse driving of the electric motor means device is performed) Control to stop is performed, and control to shut off energization of the solenoid 24 of the brake device 19 of the opening / closing machine 13 (control to turn on the brake device 19) is performed. As a result, the shutter curtain 1 stops rising by electric driving.

  On the other hand, when the fully open limit switch is not in operation while the shutter curtain 1 is electrically raised, the shutter curtain 1 is started until the first predetermined time T1 elapses after the electric curtain of the shutter curtain 1 is started. The electric rise of the car continues. Whether or not the first predetermined time T1 has elapsed since the start of the motorized raising of the shutter curtain 1 is determined by the time counted by a timer circuit (not shown) provided in the control device 27.

  When the first predetermined time T1 has elapsed since the start of the electric lifting of the shutter curtain 1, control is performed to cut off the energization of the coil 25 of the electric motor device 18 of the opening / closing device 13, thereby performing the electric motor device The reverse drive of 18 stops. Thereafter, control is performed to cut off the energization of the solenoid 24 of the brake device 19 of the opening / closing machine 13, whereby the brake device 19 is turned on. As a result, the shutter curtain 1 stops rising by electric driving.

  In the present embodiment, after the motorized rise of the shutter curtain 1 is stopped, the motored descent is started again after the second predetermined time T2 has elapsed. That is, the stop of the shutter curtain 1 is continued until the second predetermined time T2 elapses after the motorized rise of the shutter curtain 1 stops. On the other hand, when the second predetermined time T2 has elapsed after the motorized rise of the shutter curtain 1 is stopped, the above-described control for motorized lowering of the shutter curtain 1 is performed. Note that it is determined by the time counted by the timer circuit whether or not the second predetermined time T2 has elapsed since the shutter curtain 1 stopped raising the motor.

  In the present embodiment, the first and second predetermined times T1 and T2 counted by the timer circuit can be set arbitrarily, and T1 and T2 may be the same.

  In addition, since the curtain sub-portion 71B is separated from the obstacle 34 when the shutter curtain 1 in contact with the obstacle 34 is electrically lifted, the curtain sub-portion 71B is lowered relative to the curtain main portion 71A. . Thus, the pivoting member 42 in the state shown in FIG. 22 is pivoted in the C direction by the return force of the return spring 100, so that it abuts against the dog member 173 attached to the pivoting member 42. The actuating member 171 of the microswitch 170 of the second processing apparatus 38, which has been immersed in the second processing unit 38, is in the state of protruding again (see FIG. 16). As a result, the operation of the micro switch 170 is released. That is, the obstacle detection state of the electric obstacle detection device 174 is released.

  Since the micro switch 170 of the second processing unit 38 is activated again when the obstacle 34 has not been removed when the motorized shutter curtain 1 is lowered again by motoring, the control unit 27 Control for electrically raising the shutter curtain 1 described above is performed.

  As described above, in the case where the shutter device before repair according to the present embodiment functions as a management shutter device, when the shutter curtain 1 is fully opened, “2” of the operation device 30 shown in FIG. Even when the shutter curtain 1 starts closing movement by operating the “Close” button and the shutter curtain 1 in the closing movement abuts against the obstacle 34, the first lever member 61 of the mechanical coupling device 39 The second lever member 62 sandwiches and locks the folded portion 36A of the locking wire 36 in the friction members 67 and 68, and the mechanical coupling device 39 mechanically couples the shutter curtain 1 and the locking wire 36. Therefore, downward tension acts on the second portion 36C of the lock wire 36.

  When the closing movement of the shutter curtain 1 is performed by operating the “close” button of the operation device 30 as described above, the tension of the second portion 36C of the lock wire 36 is the second process. It acts on the slide member 120 of the automatic closing device 32 via the pivoting member 42 of the device 38 and the first control wire 111. Since the roller 130 of the bending lever member 129 described above is fitted in the concave portion 120B of the slide member 120 at this time, the closing movement of the shutter curtain 1 is slightly caused by the dent of the obstacle 34 or the like. It can be stopped after it descends.

  As described above, the shutter device before repair according to the present embodiment has both the function as the management shutter device and the function as the disaster prevention shutter device, and the damper is the delay device. The reference numeral 102 is for the function only as a shutter device for disaster prevention.

  Further, in the shutter device before repair according to the present embodiment, when the shutter device functions as a management shutter device, a micro that is a detection means for detecting that tension force is applied to the lock wire 36 The switch 170 is provided, and the micro switch 170 is provided in the vicinity of the damper 102 disposed in the second processing device 38.

  As described above, the shutter device before repair (in other words, before change) according to the present embodiment shown in FIGS. 1 to 22 is the shutter curtain 1 which is openable and closable, on, off Switcher 13 having a brake device 19 for stopping and moving the shutter curtain 1 by moving the shutter curtain 1, and a slide member 120 which is slidable for switching the brake device 19 on and off, The automatic closing device 32 which is a mechanical control device for mechanically controlling 13 and the shutter curtain 1, which is an obstacle existing in the moving path of the shutter curtain 1 during the closing movement. Mechanically connecting the shutter curtain 1 and the lock wire 36, which is a string-like member, when it contacts the object 34 More specifically, a mechanical coupling device 39 which causes tension force for sliding the slide member 120 to turn on the brake device 19 to the lock wire 36 by the weight of the shutter curtain 1 and the slide by removing the obstacle 34 A damper 102, which is a delay device for causing the member 120 to switch the braking device 19 from on to off and restart the shutter curtain 1 to move with a time delay from the removal of the obstacle 34. It has become.

  Next, the shutter device after repair according to the present embodiment will be described. FIG. 23 is a view similar to FIG. 1 showing the whole of the shutter device obtained by modifying the shutter device shown in FIGS. 1 to 22 described above, that is, the shutter device after the modification according to the present embodiment. In FIGS. 23 to 42 used in the following description, among members, devices and the like used for the shutter device before repair, the same symbols are used for members, devices and the like used as they are in the shutter device after repair The explanation is omitted.

  The shutter device after refurbishment according to the present embodiment is a combined (shared) shutter device for management and disaster prevention as well as the shutter device before refurbishment. That is, the shutter device after repair according to the present embodiment has a function as a management shutter device and a function as a disaster prevention shutter device.

  As described above, FIG. 23 shows the whole of the shutter device after refurbishment according to the present embodiment, and in FIG. 23, the opening / closing movement direction is the vertical direction as in FIG. 1 described above. 6 shows the shutter curtain 1 which moves downward in the downward direction is in a partially closed state in which the shutter curtain 1 is closed to about half. The opening that is opened and closed by the shutter curtain 1 is the entrance 2 formed in the building, and this entrance 2 is the lower end of the shutter curtain 1 when the left and right building frame 3 such as a wall is fully closed. It is surrounded by the floor 4 which is the opposing member to be hit, and the ceiling member 5. A pair of left and right guide rails 6 into which both end portions in the left and right direction of the shutter curtain 1, in other words, both end portions in the width direction of the shutter curtain 1 are slidably inserted, are attached to the left and right building frame 3. The shutter curtain 1 is moved up and down by being guided by these guide rails 6 which are members.

  A shutter box 8 is disposed in the ceiling space 7 partitioned by the ceiling member 5 with respect to the entrance 2, and the shutter box 8 is shown in FIG. 24 which is a sectional view taken along line S24-S24 in FIG. As it is, it is couple | bonded with the couplers 10, such as a volt | bolt, to the building frame 9, such as a down wall, which exists in the ceiling space 7. As shown in FIG. A take-up shaft 11 is horizontally accommodated inside the shutter box 8, and the take-up shaft 11 is rotatably supported by left and right side surface parts 8A and 8B of the shutter box 8 shown in FIG. There is. Further, as shown in FIG. 23, an open / close machine 13 is connected to one end of the winding shaft 11 via a driving force transmission means 12 by a sprocket wheel and a roller chain. The open / close machine 13 serving as a drive device for driving the take-up shaft 11 is also shown in FIG. 24, and the rotational force of the drive shaft 14 of the open / close machine 13 is a drive sprocket attached to the drive shaft 14 A driving force transmission means 12 is constituted by a wheel 12A, a driven sprocket wheel 12B attached to the one end of the winding shaft 11, and an endless roller chain 12C bridged between the sprocket wheels 12A and 12B. Then, it is transmitted to the winding shaft 11.

  In addition, as shown in FIG. 24, the opening / closing machine 13 of the present embodiment is attached to the bracket member 15 coupled to one of the left and right side surface portions 8A and 8B of the shutter box 8. ing.

  As can be seen from FIG. 24, the shutter curtain 1 is wound around the winding shaft 11, and the upper end of the shutter curtain 1 is coupled to the outer peripheral surface of the winding shaft 11. Further, a portion of the shutter curtain 1 below the winding shaft 11 is suspended downward of the ceiling member 5 through a slit 17 provided in the lint 16 disposed in the ceiling member 5, and further, the shutter Both ends in the width direction of the curtain 1 are slidably inserted into the left and right guide rails 6 as described above. The tufts 16 are formed by tuft members 16A and 16B disposed to face each other, and a slit 17 is formed between the tuft members 16A and 16B.

  FIG. 25 is a cross-sectional view showing the internal structure of the opening / closing machine 13. As shown in FIG. 25, the opening / closing machine 13 is formed by arranging the direct or alternating electric motor device 18 and the brake device 19 in parallel in the axial direction, and the above-mentioned drive shaft 14 is an electric motor device. The rotating shaft is disposed at the center of the eighteen rotating rotors 18A. A disc-shaped brake shoe 20 is coupled to an end of the drive shaft 14 on the side of the brake device 19. The brake device 19 is provided with a brake shaft 21 which is slidable in the axial direction by a fixed distance, and a brake drum 22 axially facing the brake shoe 20 is coupled to the brake shaft 21. The brake shaft 21 and the brake drum 22 in the normal state are pressed toward the electric motor device 18 by the spring 23. Therefore, the brake device 19 is turned on by the pressure contact between the brake shoe 20 and the brake drum 22. Therefore, the drive shaft 14 of the electric motor device 18 at this time does not rotate by the braking force of the brake device 19.

  On the other hand, when the solenoid 24 disposed in the brake device 19 is energized, the brake shaft 21 and the brake drum 22 slide away from the electric motor device 18 against the spring 23 by the magnetic force of the solenoid 24. Therefore, the pressure contact between the brake shoe 20 and the brake drum 22 is released, and the brake device 19 is turned off. Therefore, at this time, the drive shaft 14 of the electric motor device 18 can be rotated by energization of the coil 25.

  Of the left and right building housings 3A and 3B shown in FIG. 23, one of the building housings 3A has the shutter curtain 1 to the entrance 2 in the same manner as the operating device 30 provided in the shutter device before the above-mentioned renovation. An operating device 230 is attached to perform upward and downward movement, downward and movement, and movement stop. The operating device 230, which is a modified version of the shutter device operating device 30 before refurbishment (in other words, a diverted portion of the operating device 30), is the "opening of the shutter device operating device 30 before refurbishment. The "button", the "close" button, and the "stop" button are used as they are, and the function of these buttons is the same as the function of the operation device 30 of the shutter device before the repair. The shutter curtain 1 has the above-described curtain main body 1A and a seat plate 201B provided at the lower end of the curtain main body 1A. The seat plate 201B is a shutter device before refurbishment. It has the same or substantially the same shape and structure as the seat plate 1B. The curtain main body 1A of the present embodiment is formed by arranging a large number of slats in series up and down.

  The curtain main body 1A is an opening / closing body main body in the shutter device after refurbishment according to the present embodiment as the shutter device before refurbishment, and the seat plate 201B is on the closing side of the shutter curtain 1 in the curtain main body 1A. It becomes the end member in the shutter apparatus after the repair which concerns on this embodiment arrange | positioned at the edge part.

  When the shutter curtain 1 reaches the height position of the rim 16 disposed on the ceiling member 5 as described above, or when the seat panel 201B is shown in FIG. The control device 27 receives a signal from the “close” button when the “close” button of the operating device 230 is operated when the shutter curtain 1 is in the half-closed state (half-opened state) when the shutter curtain 1 reaches an intermediate position. Since the solenoid 24 of the brake device 19 is energized by the control of the above, the brake device 19 is turned off. As a result, the shutter curtain 1 causes the take-up shaft 11 and the drive shaft 14 to rotate forward by its own weight and is drawn downward from the take-up shaft 11, whereby the shutter curtain 1 moved closed is in the fully closed position. When reached, the solenoid 24 is deenergized by the control of the control device 27 to which a signal from a sensor (not shown) that has detected the fully closed position is inputted, and the brake device 19 is turned back on by the spring 23. In addition, when the shutter curtain 1 is fully closed, or the half position of the shutter curtain 1 where the seat plate 201B reaches a halfway position between the lint 16 and the floor 4 as shown in FIG. In the semi-closed state), when the "open" button is operated, the solenoid 24 of the brake apparatus 19 is energized by the control of the control apparatus 27 to which the signal from the "open" button is input. As it is turned off, the coil 25 of the electric motor device 18 is energized by the control of the controller 27. For this reason, the drive shaft 14 is reversely rotated, and this rotation is transmitted to the winding shaft 11 via the above-described driving force transmission means 12, and the shutter curtain 1 is rotated to the winding shaft 11 by the reverse rotation of the winding shaft 11. Take up and move open. When the shutter curtain 1 reaches the fully open position, the control device 27 receives a signal from a sensor (not shown) that detects the fully open position, and the energization of the solenoid 24 is cut off and the brake device 19 is turned on by the spring 23. At the same time, the control of the control device 27 shuts off the energization of the coil 25.

  In addition, if the “stop” button is operated while the shutter curtain 1 is in the closing movement, the control of the control device 27 to which the signal from the “stop” button is input shuts off the energization to the solenoid 24, When the brake device 19 is turned back on by the spring 23, the shutter curtain 1 stops at that position. Furthermore, if the “stop” button is operated while the shutter curtain 1 is moving open, the control of the control device 27 to which the signal from the “stop” button is input shuts off the energization to the solenoid 24, The brake device 19 is turned back on by the spring 23, and the control of the control device 27 cuts off the energization of the coil 25 of the electric motor device 18, whereby the shutter curtain 1 is stopped at that position.

  As can be understood from the above description, the floor 4 and the guide rails 6 described above, the shutter box 8, the bracket member 15 coupled to the shutter box 8, and the rim 16 etc. Since the floor 4, the guide rail 6, the shutter box 8, the bracket member 15, the lint 16 and the like are immovable members with respect to the shutter curtain 1.

  The downward closing movement of the shutter curtain 1 is not performed only by the own weight of the shutter curtain 1, but the closing movement of the shutter curtain 1 is performed by the own weight and the forward rotation of the drive shaft 14 by the drive of the electric motor device 18. You may make it

  Further, as described above, a return spring is provided by a torsion coil spring or a spiral spring whose return force is accumulated during the closing movement of the shutter curtain 1 on the take-up shaft 11 which is rotatable in forward and reverse directions. The upward opening movement of 1 may be performed using the return force accumulated in the return spring as an auxiliary force.

  In the present embodiment, as shown in FIG. 25, the lever member 31 is disposed at the end of the brake shaft 21 opposite to the electric motor device 18. The lever member 31 penetrates the brake shaft 21 and includes a first portion 31A and a second portion 31B which are divided with the brake shaft 21 as a boundary. A first bent portion 31C is formed in the first portion 31A, and a second bent portion 31D is formed in the second portion 31B. When a load acts on the first portion 31A in the A direction, that is, on the side opposite to the electric motor device 18, the first portion 31A swings in the A direction with the second bending portion 31D as a fulcrum, so the brake shaft 21 and the brake drum 22 slide in the A 'direction which is the same direction as the A direction. Therefore, the brake device 19 can be turned off without energizing the solenoid 24.

  Therefore, the brake device 19 is also a mechanical brake device that is turned on and off by the action of the load in the A direction on the first portion 31A and the spring 23 when the load is released.

  24 is a cross-sectional view taken along line S24-S24 in FIG. 23, and is similar to FIG. 2 described above. FIG. 25 is a cross-sectional view showing the internal structure of the opening / closing machine 13, and is the same as FIG. 3 described above.

  The fact that the load in the A direction acts on the first portion 31A of the lever member 31 of the brake device 19 shown in FIG. 25 means that the shutter device after refurbishment is attached to the open / close machine 13 as shown in FIG. This is performed by an automatic closing device 232 described later, which is a component of the multifunction device 300 shown in FIG. The automatic closing device 232 is a mechanical control device for mechanically controlling the brake device 19 of the opening / closing device 13 serving as a driving device of the shutter curtain 1 as understood from the description below.

  Also, when a load in the same direction as the A direction acts on the second portion 31B, the second portion 31B swings in the same direction as the A direction with the first bending portion 31C as a fulcrum, so in this case as well, the brake shaft 21 and the brake drum 22 slide in the A 'direction. Therefore, the brake device 19 can be turned off without energizing the solenoid 24 also at this time.

  Applying a load in the same direction as the A direction to the second portion 31B in this manner can be performed manually. Therefore, the open / close machine 13 according to this embodiment can turn off the brake device 19 even by a manual operation. The second portion 31B may be omitted leaving the second bent portion 31D.

  26 is a cross-sectional view taken along line S26-S26 in FIG. 23, showing the structure of the portion of the seat plate 201B of the shutter curtain 1 shown in FIG. The shutter curtain 1 of the shutter device after refurbishment according to the present embodiment includes the curtain main body 1A and the seat plate 201B as described above, and the seat plate 201B includes the fixed portion 270A and the movable portion 270B. The shutter curtain 1 has a curtain main portion 71A and a curtain sub-portion 271B of the shutter device before refurbishment, and the curtain main portion 71A is formed by the curtain main body 1A and the fixed portion 270A of the seat plate 201B. The curtain sub-portion 271B is configured by the movable portion 270B of the seat plate 201B. Therefore, the curtain sub-portion 271 B is disposed at the closing end of the shutter curtain 1. The curtain main portion 71A is an opening / closing body main portion in the shutter device after refurbishment according to the present embodiment, and the curtain sub portion 271B is the opening / closing member sub portion in the shutter device after refurbishment according to the present embodiment. It has become.

  Further, as shown in FIG. 26, the fixed portion 270A of the seat plate 201B coupled to the curtain main body 1A is formed of the inner and outer members 275 and 276, both of which have a box shape in cross section. The movable portion 270B is vertically movable with respect to 270A. As can be seen from FIG. 26, the lower surface of the inner and outer members 275 and 276 forming the fixed portion 270A is an opening 278, and the upper end of the rising portion 279 of the movable portion 270B from the opening 278 is the fixed portion 270A. It is inserted in the internal space of. At the upper end of the rising portion 279, extending portions 279A, 279B extending outward in the thickness direction of the shutter curtain 1 are formed, and these extending portions 279A, 279B are at the lower end of the inner member 276 of the fixed portion 270A. By riding on the upper surfaces of the formed projecting pieces 276A and 276B, the downward movement limit of the movable part 270B with respect to the fixed part 270A is defined. The seat plate 201B is coupled to the lower end portion of the curtain main body 1A by a connector 77 such as a bolt or a nut, as in the case of the seat plate 1B described above. Therefore, the seat plate 201B is attachable to and detachable from the curtain main body 1A.

  In the inside of the fixing portion 270A, a swinging member 281 which is vertically swingable about a fulcrum shaft 280 extending in the width direction of the shutter curtain 1 is accommodated. As shown in FIG. 27, when the movable portion 270B ascends with respect to the fixed portion 270A, that is, when the shutter curtain 1 in closing movement abuts against the obstacle 34 shown in FIG. When the extension portion 279A of the rising portion 279 of the portion 270B pushes up the swinging member 281, the swinging member 281 swings upward about the fulcrum shaft 280.

  As shown in FIGS. 26 and 27, a case 233 shown also in FIG. 23 is attached to the fixed portion 270A of the seat plate 201B, and the inside of the case 233 is as shown in FIGS. Is shown. As shown in FIG. 30, inside the case 233, there is provided a rotating member 235, which is a ratchet hole type gear, in which a large number of tooth portions 235A are formed at equal intervals in the circumferential direction at the outer peripheral portion. The take-up reel 237 is rotatably housed around a shaft 241 which is a fixed shaft fixed to the case 233 as described later, and is coaxial because the rotation central axis is the shaft 241. The rotating member 235 and the take-up reel 237 are integrally connected as described later. Further, the lower end of the lock wire 236 is connected to the take-up reel 237, and the lower portion of the lock wire 236 extending downward from the portion of the above-mentioned rib 16 is a rotation center inside the case 233. An upper portion of the lock wire 236 extends upward from the upper surface of the case 233 through a guide roller 229 rotatably accommodated around a shaft 229 A and wound around a take-up reel 237. The upper end of the locking wire 236 then extends to the redirecting device 238 shown in FIGS. 23, 24 and 36.

  In the above, the lock wire 236, of which the lower part is taken up freely to the take-up reel 237, is a flexible string-like member. Then, when the shutter curtain 1 moves in the downward direction, the shutter curtain 1 moves in the closing direction while the lock wire 236 is drawn out from the take-up reel 237 rotating in the Y direction about the shaft 241 of FIG. .

  FIG. 29 shows an overall front view of the case 233 in which the rotating member 235, the take-up reel 237, and the guide roller 229 are accommodated, and FIG. 32 is a sectional view taken along line S32-S32 in FIG. A diagram is shown. As shown in FIG. 32, a return spring storage space 237A (see also FIG. 30) is provided inside the take-up reel 237 in which a groove 237B for taking up the lock wire 236 is formed on the outer peripheral portion. A return spring 239, which is shown partially omitted in FIG. 30, is housed in the return spring housing space 237A, and an axis which is a central axis of rotation of the rotating member 235 and the take-up reel 237. The return spring 239 wound around the outer periphery of the spring 241 is a mainspring. For this reason, the return spring 239 is a spiral spring in which the shaft 241 is inserted in the center.

  The inner end which is one end of the return spring 239 is fixed to the case 233 and is connected to the shaft 241 which is a member on the case 233 side, and the outer end which is the other end will be described later. As such, it is connected to the rotating member 235 and the take-up reel 237. Therefore, when the rotary member 235 and the take-up reel 237 rotate in the Y direction in FIG. 30 and the shutter curtain 1 is moved downward as the shutter curtain 1 moves downward, the return spring 239 is wound to rotate for unwinding the lock wire 236. When the return spring force is accumulated by the take-up reel 237 and the shutter curtain 1 is moved open upward, the rotating member 235 and the take-up reel 237 are in the Z direction opposite to the Y direction by the return spring force accumulated in the return spring 239 By rotating in the direction, the lock wire 236 is wound on the take-up reel 237.

  For this reason, in the shutter device after modification according to the present embodiment, the winding reel 237 and the return spring 239 constitute a winding device 240 for winding the lock wire 236 freely. Further, when the shutter curtain 1 is moved in the opening and closing direction, the rotating member 235 and the take-up reel 237 are rotated by the lock wire 236.

  In the shutter device after modification according to the present embodiment, since the return spring 239 which is a spiral spring by the mainspring spring is housed in the space 237A formed inside the take-up reel 237, the shutter for the case 233 is Even if the dimension in the thickness direction of the curtain 1 is small, the dimension in the thickness direction of the shutter curtain 1 with respect to the take-up reel 237 can be made sufficiently large, as can be seen from FIG. Thus, the winding length of the lock wire 236 is sufficiently long, and the shutter curtain 1 can be adapted to a shutter device having a long opening and closing movement distance.

  As shown in FIG. 30, inside the case 233, there is accommodated a lock member 250 which is vertically pivotable about a shaft 256 provided in the case 233. As shown in FIG. The lock member 250 of this embodiment includes a main member 252 not having the toothed portion 253 engageable with the toothed portion 235A of the rotating member 235 which is a ratchet wheel type gear, and the shutter curtain 1. It comprises a sub member 251 fastened to the main member 252 having a length in the width direction and having a toothed portion 253. Thus, by forming the lock member 250 as a combined structure in which the sub member 251 and the main member 252, which are separate parts, are superimposed in the thickness direction of the shutter curtain 1, the tooth portion 235A of the rotating member 235 is formed. Even if the entire lock member 250 is not quenched or the like by quenching the sub member 251 in which the tooth portion 253 to be engaged is formed, the tooth portion 253 is similar to the tooth portion 235A of the rotating member 235 , Can give great strength. Further, by making the sub member 251 made of a hard metal harder than the main member 252 or the like, the entire lock member 250 may not be formed of an expensive hard material.

  In the shutter device after modification according to the present embodiment, a plurality of teeth portions 253 of the lock member 250 are separated in the rotational direction of the lock member 250 around the shaft 256, as shown in FIG. These tooth portions 253 are provided with a first tooth portion 253A, a second tooth portion 253B, and a third tooth portion 253C in the shutter device after refurbishment according to the present embodiment. The tooth portions 253A, 253B, 253C are provided on a circular arc or a substantially circular arc centering on the shaft 256 which is a central portion of the rotation of the lock member 250.

  Further, as shown in FIG. 26, a swinging member disposed so as to be vertically swingable around a fulcrum shaft 280 inside the fixed portion 270A (the curtain main portion 71A) of the seat plate 201B described above. The pressing member 254 is attached to the 281.

  As can be seen from FIG. 30, the lock member 250 is provided with a torsion coil spring 257. As shown in FIG. 35, one end 257B of the torsion coil spring 257 in which the coil portion 257A is wound around the outer periphery of the large diameter portion 256B of the shaft 256 includes the main member 252 and the sub member 251. The other end 257C is locked to the lock member 250 by being inserted into the long hole 250A formed on the other end of the case 233 shown in FIG. Among them, it is locked to the case 233 by being inserted into the hole of the bent portion 233D formed at the lower end of the side portion 233C shown in FIG. Therefore, the torsion coil spring 257 is provided between the shaft 256 and the lock member 250 and the case 233, and the lock member 250 is centered on the shaft 256 by the spring force of the torsion coil spring 257 in FIG. It is rotationally biased in the W direction. As a result, a part of the lock member 250 swings up and down around the fulcrum shaft 280 provided on the pressing member 254 provided on the shutter curtain 1, that is, on the curtain main portion 71A of the shutter curtain 1. It is in contact with a pressing member 254 disposed on the member 281.

  For this reason, when the shutter curtain 1 in the closing movement abuts against the obstacle 34, the locking member 250 is in the W direction of FIG. The shutter curtain side contact portion 258 and the lock member side contact portion 259 are provided to be in contact with each other in order to rotate in the opposite direction, the X direction. The shutter curtain side contact portion 258 is formed by the pressing member 254, and the lock member side contact portion 259 is formed by the first lock member side contact portion 259A and the second lock in the main member 252 of the lock member 250. There are two member-side contact portions 259B. The first lock member side contact portion 259A and the second lock member side contact portion 259B are separated in the width direction of the shutter curtain 1, which is the length direction of the lock member 250.

  Providing the first lock member side contact portion 259A and the second lock member side contact portion 259B to the lock member 250 constitutes the lock member 250 as shown in FIGS. 30 and 35. This can be realized by making the portion of the main member 252 not overlapping the sub member 251 into an L shape or a substantially L shape.

  In the shutter device after modification according to the present embodiment, the first lock member side contact portion 259A of the lock member side contact portion 259 is formed by a plate spring 260 coupled to the main member 252. Therefore, the first lock member side contact portion 259A is an elastic portion that can be elastically deformed.

  In addition, as shown in FIGS. 28 and 30, the main member 252 of the lock member 250 is an extension member having a length extending on both sides in the thickness direction of the lock member 250 which is the thickness direction of the shutter curtain 1. The extension member 263 is formed of a rod-like member that penetrates the main member 252. As shown in FIG. 28, a bent stop portion 233E is provided at the lower end of the side face portion 233C of the case 233. Therefore, the case 233 in which the lock member 250 and the like are accommodated and arranged. Before the lock member 250 is attached to the fixed portion 270A of the seat plate 201B of the shutter curtain 1, even if the lock member 250 is pivoted in the W direction of FIG. 30 about the shaft 256 by the spring force of the torsion coil spring 257, When the end of the extension member 263 abuts on the stop portion 233E, the rotation limit of the lock member 250 in the W direction is defined, whereby the first lock member side contact portion 259A of the lock member 250 is large. Protruding from the lower surface opening of 233 can be eliminated.

  As shown in FIG. 27, when the seat plate 201B of the shutter curtain 1 in the closing movement comes in contact with the obstacle 34 shown in FIG. 23, etc., the fixing portion 270A of the seat plate 201B of the shutter curtain 1 ( When the movable portion 270B (curtain sub-portion 271B) is relatively raised with respect to the curtain main portion 71A), the swinging member 281 swings upward about the fulcrum shaft 280. In FIG. 30, 250 rotates about the axis 256 in the X direction. Thereby, as shown in FIG. 31, the teeth 253 of the locking member 250 engage with the teeth 235A of the rotating member 235, and by this engagement, the rotating member 235 and the rotating member 235 are coupled. The integrated take-up reel 237 can not rotate in the rotational direction (Y direction in FIG. 30) when the shutter curtain 1 is moving in the closing direction, and thus the rotating member 235 and the take-up reel 237. Is locked by the lock member 250 and can not rotate.

  Therefore, at this time, the lock wire 236 partially wound on the take-up reel 237 and the shutter curtain 1 on which the take-up reel 237 is disposed are mechanically coupled. Therefore, in the shutter device after modification according to the present embodiment, a mechanical coupling device for mechanically coupling the lock wire 236, which is a string-like member, and the shutter curtain 1 by the rotation member 235, the lock member 250, and the like. 255 will be configured.

  In the present embodiment, the mechanical coupling device 39 in the shutter device before repair shown in FIGS. 1 to 22 described above is changed to the mechanical coupling device 255 in the shutter device after renovation, and this mechanical coupling The device 255 is provided with a plurality of teeth 235A at its outer periphery, and can be engaged with the rotating member 235 which is rotated by the lock wire 236 when the shutter curtain 1 moves, and the teeth 235A of the rotating member 235. The teeth portion 253 which is an engaged portion is provided, and when the shutter curtain 1 in the closing movement abuts against the obstacle 34, it moves (rotates), and the teeth portion 253 becomes a tooth by this movement (rotation). And a lock member 250 which engages with 235A to make the rotation member 235 non-rotatable.

  For this reason, in the present embodiment, the mechanical coupling device 39 in the shutter device before modification is the mechanical coupling device before being changed (in other words, the first mechanical coupling device), and the shutter after modification is The mechanical coupling device 255 in the device is a mechanical coupling device after being changed (in other words, a second mechanical coupling device).

  As described above, the lock member 250 is configured by overlapping the main member 252 having a length in the width direction of the shutter curtain 1 and the sub member 251 in the thickness direction of the shutter curtain 1, and As shown in FIG. 35, the sub member 251 is attached to the main member 252 so as to be rotatable about the rotation center shaft 261. In the main member 252, an arc-shaped long hole 252A centered on the rotation center shaft 261 is formed, and in this long hole 252A, a screw member for fastening inserted from the round hole of the sub member 251 is used. The shaft portion of the bolt 262 is inserted, and the end portion of the shaft portion of the bolt 262 protruding from the long hole 252A is screwed to a nut which is detentated to the main member 252 and movably disposed along the long hole 252A. By inserting the bolt 262 and tightening the bolt 262, the sub member 251 is fastened to the main member 252 with the bolt 262 and a nut. Further, when the bolt 262 is loosened, the sub member 251 can be rotated relative to the main member 252 by the elongated hole 252A guiding the shaft portion of the bolt 262 about the rotation center shaft 261. When the bolt 262 is later tightened, the position relative to the main member 252 is changed, and the adjusted secondary member 251 can be refastened to the main member 252 with the bolt 262 and the nut.

  For this reason, in the shutter device after repair according to the present embodiment, the bolt 262 in which the shaft portion is screwed to the nut serves as a fastening member for fastening and releasing the main member 252 and the sub member 251. There is.

  The small diameter portion 256A of the shaft 256 is inserted into the round hole of the main member 252 so that the sub member 251 can be rotated about the rotation center shaft 261 with respect to the main member 252. As shown in FIG. 35, the hole 251A formed in the sub member 251 for inserting the small diameter portion 256A is an arc-shaped elongated hole centered on the rotation center shaft 261. It has become. The coil portion 257A of the above-described torsion coil spring 257 is wound around the outer periphery of the large diameter portion 256B of the shaft 256.

  In the shutter device after modification according to the present embodiment, the position of the sub member 251 with respect to the main member 252 is more specifically determined by the rotation center shaft 261 and the bolt 262 in which a nut is screwed to the shaft portion. The position adjusting means 264 shown in FIG. 35 is configured to adjust the position of the sub member 251 with respect to the main member 252 centered on the rotation center shaft 261.

From the position of the above-mentioned axis 256 which is the central axis, it is offset in the width direction of the shutter curtain 1 which is the length direction of the lock member 250, and this offset direction is pivoted as can be seen from FIG. The position of the central axis 261 is in the direction opposite to the rotational member 235 with respect to the axis 256.

  The both ends of the shaft 256, which is the central axis of the rotation of the entire lock member 250, are inserted into the holes formed in both side portions 233B and 233C of the case 233 shown in FIG. These holes are shown as long holes 267 in FIGS. The longitudinal direction of the elongated hole 267 is a direction toward the rotating member 235. That is, the holes 267 formed for inserting and supporting both ends of the shaft 256 in the case 233 are long holes that are elongated toward the rotating member 235. For this reason, the lock member 250 and the shaft 256 are movable in the approaching and separating directions with respect to the rotating member 235.

  The coil portion 257A is wound around the outer periphery of the shaft 256, and a torsion coil spring 257 provided between the case 233 and the shaft 256 and the lock member 250 is used to apply the spring force to the shaft 256 and the lock member 250. The torsion coil spring 257 is constantly urged toward the rotating member 235 shown by the arrow X in FIG. 35, and the torsion coil spring 257 is an elastic member having such an urging force. When the shaft 256 is pressed against the end of the long hole 267 on the side of the rotating member 235 by the elastic biasing force of the elastic member, the size of the gap 265 becomes the size set by the gap adjusting means 266.

The closing member axial direction position defining portion 246 can also be formed by performing half-blanking processing, drawing processing, or the like on the lid member 286 made of sheet metal.

  By providing the take-up reel axial position defining portion 245 and the closing member axial position defining portion 246 on the lid member 286, as shown in FIG. 32, the rotating member 235 is the main portion 285A of the case main body 285. The position of the rotating member 235 and the take-up reel 237 in the axial direction of the shaft 241 can be defined. In other words, the take-up reel provided in the lid member 286 even when the return spring storage space 237A provided inside the take-up reel 237 to store the return spring 239 is a penetrating space axially penetrating as described above. The positions of the rotating member 235 and the take-up reel 237 in the axial direction of the shaft 241 can be defined by the axial position defining portion 245 and the closing member axial position defining portion 246, whereby the tooth portion 253 of the locking member 250 can be It is possible to more reliably engage the teeth 235A of the rotation member 235.

  As shown in FIG. 32, the shaft 241 is formed with a split groove 241A cut from the end on the lid member 286 side, and the split groove 241A is a spiral spring made of a mainspring spring. One end of the spring 239, an inner end 239A, is inserted and locked, whereby the inner end 239A is connected to the shaft 241. In addition, a loop portion 239B is formed at an outer end which is the other end of the return spring 239 (see also FIG. 30).

  As can be seen from FIG. 32, an insertion portion 235B is formed in the plate-like rotating member 235 by cutting and raising processing, and the insertion portion 235B is inserted into the inside of the loop portion 239B. Further, the insertion portion 243C is also formed in the closing member 243, and the insertion portion 243C is provided at a position where the above-mentioned flange portion 243B of the closing member 243 is notched, as can be seen in FIG. 243C is also inserted inside the loop portion 239B. Thus, the loop portion 239 B, which is the outer end of the return spring 239, is connected to the rotating member 235, the take-up reel 237 coupled to the rotating member 235 by the coupler 242, and the closing member 243. It will be. For this reason, as described above, when the shutter curtain 1 is moved to close downward and the rotating member 235 and the take-up reel 237 rotate in the Y direction in FIG. When the return spring force is accumulated by the take-up reel 237 that rotates to move the shutter curtain 1 upward, the rotating member 235 and the take-up reel 237 are moved in the Y direction by the return spring force accumulated in the return spring 239. Is rotated in the reverse Z direction, the lock wire 236 is wound on the take-up reel 237.

  The insertion portion 235B of the rotation member 235 and the insertion portion 243C of the closing member 243 are inserted into the loop portion 239B of the return spring 239, whereby the rotation member 235 and the closing member 243 are connected via the loop portion 239B. Therefore, even if the closing member 243 is not coupled to the take-up reel 237 with a screw or the like, or the flange portion 243B of the closing member 243 is input to the return spring storage space 237A of the take-up reel 237 The rotary member 235 and the closing member 243 can be coupled in the direction of rotation about the shaft 241 only by not pressing in or by simply inserting without pressing.

  As shown in FIG. 32, among the both ends of the shaft 241, the end on the main portion 285A side of the case main body 285 protrudes from the main portion 285A, and the spacer 247 and the rotating member are provided at this protruding end. The rotary plate 248 and the retaining member 249 are attached, and the rotary plate 248 is integrally coupled with the shaft 241. FIG. 33 is a view taken in the direction of the arrow S33 in FIG. 32, and as shown in FIG. A plurality of holes 248A are provided at equal intervals in the circumferential direction centering on. Further, as shown in FIG. 32, an opening 285F for inserting the lower part of the rotary plate 248 is formed in the above-mentioned stepped portion 285E of the case main body 285.

  Of the main portion 285A of the case main body 285, the second surface portion 289 lower than the step portion 285E is provided with a projecting portion 285G projecting to the rotary plate 248 side by cutting and bending or the like, and the projecting portion 285G The shaft portion of a bolt 301, which is a pin-like member, is screwed into the formed screw hole 285H, and this shaft portion can be inserted into the hole 248A of the rotary plate 248. By performing this insertion, the rotary plate 248 and the shaft 241 to which the rotary plate 248 is coupled are non-rotatably fixed to the case 233.

  Further, after the shaft portion of the bolt 301 is pulled out from the hole 248A by the rotation operation of the bolt 301, the shaft is operated by rotating the rotary plate 248 or by a tool engaged with the engagement groove 241B provided on the shaft 241. By performing the rotation operation of 241, the shaft 241 can be rotated with respect to the case 233. When this rotation is performed, the return spring 239 whose inner end 239A is connected to the shaft 241 and wound around the periphery of the shaft 241 has its inner end 239A rotationally moved in the circumferential direction of the return spring 239. Therefore, in order to be tightened or relaxed according to the rotation direction of the shaft 241, the spring force of the return spring 239, which is a spiral spring by the mainspring spring, is adjusted. The shaft 241 is again fixed non-rotatably to the case 233 by inserting the shaft portion of the bolt 301 into the hole 248A of the rotary plate 248 reaching the portion facing the shaft portion later.

  For this reason, the return spring 239 is disposed by the shaft 241 and the rotary plate 248, and further by the bolt 301 or the like which is disposed in the screw hole 285H of the case 233 and can be inserted and removed from the hole 248A of the rotary plate 248. Spring force adjusting means 302 is configured to adjust the magnitude of the spring force. The spring force adjustment means 302 is a means configured to rotate the inner end of the return spring 239 by rotating the shaft 241.

  The bolt 301, which is a pin-like member, is formed in one of the holes 248A of the holes 248A circumferentially formed around the shaft 241 in the rotary plate 248 and in the case 233. By being inserted into the screw holes 285 H, the connecting member is used to connect the rotating plate 248 after rotation around the shaft 241 and the case 233.

  According to this spring force adjustment means 302, even if the spring force of the return spring 239 changes due to repeated opening and closing movement of the shutter curtain 1, aged deterioration, etc., the return wire is wound to take up the lock wire 236 on the take-up reel 237. The magnitude of the return spring force accumulated in 239 can be adjusted to an appropriate value.

  Further, the spring force adjustment means 302 adjusts the spring force of the return spring 239 to, for example, a size according to the upper and lower opening and closing movement strokes of the shutter curtain 1 shown in FIG. It can also be used to adjust to an appropriate size when the shutter curtain fully reaches the position of the lint 16.

  Furthermore, adjusting the spring force of the return spring 239 in the spring force adjusting means 302 of the present embodiment rotates the rotary plate 248 or engages a tool in the engagement groove 241B provided on the shaft 241, Since the tool is used to rotate the shaft 241 with this tool, the location of the rotary plate 248 and the location where the engagement groove 241B of the shaft 241 is provided are operation locations operated by the spring force adjustment means 302. . In this embodiment, as shown in FIG. 26, the operation portion and the case 233 in which the take-up reel 237 is accommodated are juxtaposed in the thickness direction of the shutter curtain 1. The operation point is disposed between the case 233 and the above-described curtain main body 1A of the shutter curtain 1.

  According to this, after attaching the case 233 to which the spring force adjustment means 302 is assembled in advance to the fixing portion 270A of the seat plate 201B of the shutter curtain 1, after the spring force adjustment, the operator or the like erroneously It is possible to prevent the operation part from being operated. Therefore, after the case 233 is attached to the fixing portion 270A of the seat plate 201B of the shutter curtain 1, the spring force of the return spring 239 can be maintained at the adjusted size.

  In order to allow the operator etc. to operate the spring force adjusting means 302 even after the case 233 is attached to the fixing portion 270A, the operating position of the spring force adjusting means 302 is the shutter curtain 1 of the case 233. You may provide in the location on the opposite side to the curtain main body 1A.

  Further, as shown by a two-dot chain line in FIG. 32, among the members constituting the lock member 250 described above, the main member 252 ′ is extended to the side surface of the rotation member 235 beyond the sub member 251. It is good also as what has a part. According to this, in the portion facing the second surface portion 289 of the main portion 285A of the case main body 285 in the rotating member 235, a space portion exists between this portion and the second surface portion 289. The extension of the main member 252 'can prevent displacement of the rotating member 235 and the take-up reel 237 to the side of the second surface 289 by the extension of the main member 252'. Thus, the engagement of the 250 auxiliary members 251 with the teeth 253 can be realized more reliably.

  Further, in the case of providing the portion extended to the main member 252 ′ in this manner, the window hole provided for inserting the inspection tool such as the clearance gauge into the lid member 286 of the case 233 and the case main body 285 as described above. A hole similar to 286A may be provided in this extended portion.

  Furthermore, according to the present embodiment, since the take-up reel 237 and the return spring 239 are disposed in the seat plate 201B which is housed inside the case 233 and serves as the end member of the shutter curtain 1 described above, The take-up reel 237 and the return spring 239 can be effectively protected from external force or the like at the time of opening and closing movement of the shutter curtain 1 or the like. Since the mechanical coupling device 255 described above is also housed inside the case 233 and disposed in the seat plate 201B of the shutter curtain 1, the mechanical coupling device 255 also moves when opening and closing the shutter curtain 1, etc. It can be effectively protected from external force and the like.

  As shown in FIG. 30, the case 233 is provided with a guide member 303 for guiding the lock wire 236 described above. The guide member 303 formed of a synthetic resin is, inside the case 233, the first guide portion 303A facing the outer periphery of a part of the guide roller 229 described above, and the lock wire 236 inside and outside of the case 233. And a second guide portion 303B partially exposed to the outside of the case 233 and the other portion housed inside the case 233, and the second guide portion 303B. A hole 303 C through which the lock wire 236 is vertically inserted is formed as an elongated hole elongated in the width direction of the shutter curtain 1 in the inside of the shutter.

  The first guide portion 303A is disposed at a position near the outer peripheral surface of the guide roller 229 between the guide roller 229 and the lock member 250 disposed below the guide roller 229. Therefore, even if the lock wire 236 may be loosened before the case 233 is attached to the shutter curtain 1, the first guide portion 303A prevents the loosened portion from reaching the lock member 250. Can. In addition, when the tension of the portion of the lock wire 236 wound around the guide roller 229 disappears at the time of opening and closing movement of the shutter curtain 1 at the upper and lower sides, this portion may contact the lock member 250. This can be prevented by the first guide portion 303A, and it can be ensured that the shutter curtain 1 moves normally. That is, the first guide portion 303A of the guide member 303 can prevent the lock wire 236 from being caught in the lock member 250 or the like.

  FIG. 34 is a cross-sectional view taken along line S34-S34 in FIG. As shown in FIG. 34, both ends of the above-described extending member 263 fixed to the main member 252 of the locking member 250 through the thickness of the locking member 250 are shutter curtains in the case 233. They are in contact with the inner surfaces of the two side portions 233B and 233C which are opposed to each other in the thickness direction of 1 or face the inner surfaces of the side portions 233B and 233C with a slight gap. The position of the lock member 250 where the extension member 263 is disposed is the length of the lock member 250 which is the width direction of the shutter curtain 1 from the above-mentioned shaft 256 which is the rotation center axis of the entire lock member 250. It is a distant place in the direction. For this reason, as described above, when the shutter curtain 1 in closing movement abuts against the obstacle 34, when the lock member 250 rotates in the X direction in FIG. 30 about the shaft 256, or in the W direction When the lock member 250 swings in the thickness direction of the lock member 250 (in the thickness direction of the shutter curtain 1 and in the thickness direction of the rotation member 235 described above) when rotating, it is stretched. It is blocked by member 263.

  For this reason, as can be seen from FIG. 28, the rotation member 235 is formed of a plate material having a small thickness dimension, and the sub member 251 of the lock member 250 having the tooth portion 253 engaged with the tooth portion 235A of the rotation member 235. Even if the lock member 250 is formed of a plate-like material having a thickness similar to that of the rotation member 235, the extension member 263 prevents the lock member 250 from swinging in the thickness direction of the lock member 250 about the shaft 256. Therefore, when the lock member 250 is pivoted in the X direction in FIG. 30 about the shaft 256 by the shutter curtain 1 in the closing movement abutting on the obstacle 34, the teeth of the sub member 251 of the lock member 250. The portion 253 can be engaged with the tooth portion 235A of the rotation member 235 more securely.

  Therefore, the extension member 263 stops the lock member 250 from swinging in the thickness direction of the lock member 250 around the shaft 256, in other words, in the axial direction of the shaft 256 and in the thickness direction of the rotary member 235. The lock member of the present invention is a means for anti-vibration.

  When the lock member 250 swings in the thickness direction of the lock member 250 about the shaft 256, the size of the hole of the lock member 250 through which the shaft 256 is inserted and the case in which both ends of the shaft 256 are inserted. This occurs when the size of the hole 233 is not an accurate predetermined value and is larger than the predetermined value. For this reason, according to the present embodiment, by providing the extension member 263 in the lock member 250, it becomes unnecessary to set the size of these holes to an accurate predetermined value, and these holes can be easily processed. Become.

  Moreover, the extending member 263 of the present embodiment is made of, for example, a hard synthetic resin having a smaller coefficient of friction than metal. Therefore, even if the both end portions of the extension member 263 contact the inner surfaces of the side surface portions 233B and 233C of the case 233 made of metal, smooth rotation of the lock member 250 around the shaft 256 is achieved. It can be guaranteed.

  As shown in FIG. 37, the second slide member 410 which is a component of the intermediate device 400 is at a height position above the first slide member 320 which is a component of the automatic closing device 232. , And the frame 310. Further, as shown in FIG. 39 (A), the second slide member 410 is compared with the first and the second connection members 338A of the connection member 338 provided on the first slide member 320. On the advancing side of the two slide members 320 and 410, there is provided a step surface 410B formed opposite to the slide members 320 and 410 in the forward and backward direction. As shown in FIG. 37, the connecting portion 338A has a length extending upward, and the connecting portion 338A and the step surface 410B are provided at the normal time shown in FIGS. 39 (A) and (B). A large distance in the moving direction of the first and second slide members 320 and 410 is opposite to each other. Then, as shown in FIGS. 40 (A) and (B) and FIGS. 41 (A) and (B), when the first slide member 320 advances, the connecting portion 338A abuts on the step surface 410B or opens a slight gap. After the second slide member 410 is retracted as shown in FIG. 42 (A) after facing each other, as shown in FIG. 42 (B) by the pressing action of the connecting portion 338A by the step surface 410B, the first slide member The 320 is also set back.

  As can be understood from the above description, the intermediate device 400 serving as a connection device for directly connecting the first control wire 311 and the automatic closing device 232 described above includes the first rotation member 401 and the second rotation member. The first control member 401 is constituted by a moving member 402, a second slide member 410, and the like, and the first rotation member 401 of the first rotation member 401 and the second rotation member 402 is a string-like member. The second pivoting member 402 is a member on the side of the first slide member 320 which is the above-described switching member of the automatic closing device 232 while being a member on the side of the wire 311. In addition, the first pivoting member 401 is a pivoting abutment member because the above-mentioned side surface 401D is in contact with the convex portion 408 of the second pivoting member 402. The pivoting member 402 is also a pivotable contactable member that is in contact with the contact member.

  As described above, the second pivoting member 402 is provided with the fan-shaped portion 402B centered on the central axis 402A, and as shown in FIG. 39A, the fan-shaped portion 402B is A large number of teeth 402D are formed on the outer peripheral surface. A pinion gear 300B coupled to the rotatable central shaft 500A of the above-described delay device 500 is in mesh with these teeth 402D. The delay device 500 is a rotary damper, and a plurality of blades connected to the central shaft 500A via the one-way clutch is attached to the inside of the delay device 500, and the second pivoting member 402 is the central shaft. When the pinion gear 300B and the central shaft 500A rotate in the Q direction by rotating in the S direction centering on 402A, the viscosity in which the respective blades are filled in the delay device 500 by the connecting action of the one-way clutch It rotates in the fluid. For this reason, the second pivoting member 402 pivots in the S direction at a low speed by the resistance force of the viscous fluid. On the other hand, when the second rotation member 402 rotates in the T direction opposite to the S direction, and the pinion gear 300B and the central shaft 500A rotate in the R direction, the rotation in this direction is the cutting action of the one-way clutch. Is not transmitted to each blade. Therefore, the second pivoting member 402 can pivot in the T direction at high speed.

  The delay device 500 that operates as described above is disposed inside the machine frame 310 of the multifunction peripheral 300 by being attached to the lower surface of the bracket 403 described above, as shown in FIGS. 37 and 38. It is done.

  As described above, in the modified shutter device, the lock wire 236 extending in the opening movement direction of the shutter curtain 1 from the mechanical coupling device 255 serving as the second mechanical coupling device is in a string shape by the coupling member 294. The first control wire 311, which is a member, is connected to the automatic closing device 232 through the intermediate device 400. That is, the lock wire 236 is connected to the automatic closing device 232 via the intermediate device 400. Further, the delay device 500 delays the operation of the intermediate device 400, that is, the rotation of the second pivoting member 402 of the intermediate device 400.

  Further, as shown in FIG. 39 (A), the second electric switch 420 is attached to the machine frame 310, and the second electric switch 420 is attached in a direction of protruding from the second electric switch 420 by a spring. It has a pivotable actuator 421 that is biased. Further, the first pivoting member 401 is provided with a projecting member 422, and the actuator 421 is in contact with the projecting member 422.

  Next, the operation of the shutter device after refurbishment according to the present embodiment will be described.

  In a building where a post-renovation shutter device according to the present embodiment is installed, when a disaster such as a fire occurs while the shutter curtain 1 is stopped at a fully open position or an open / close movement direction halfway position, this disaster is detected By control of an electric circuit such as a relay circuit (not shown) to which a signal from a sensor is input or a control device by a computer (this control device may also be used as the control device 27 in FIG. 23), in FIG. The solenoid 326 of the automatic closing device 232 shown is energized, and since the solenoid 326 is energized, the plunger 327 of the solenoid 326 retracts against the spring force of the spring 328. Thus, the bending lever member 329 whose one end is in contact with the above-mentioned tip member 340 is against the spring force of the spring 331 and is opposite to the U direction in FIG. 39B about the central shaft 329A. It will rotate in the direction V of the direction. The state at this time is shown in FIG. 40 (B). When the bending lever member 329 pivots in the V direction about the central axis 329A, the roller 330 of the bending lever member 329 escapes from the recess 320B of the first slide member 320. The forward movement is stopped by the front end of the connecting member 338 provided on the first slide member 320 abutting on the aforementioned rising portion 310B of the machine frame 310. That is, the connecting member 338 of the present embodiment also serves as an advancing limit defining portion in the first slide member 320 for defining the advancing limit of the first slide member 320.

  The position of the front end of the first slide member 320 at this time is as shown in FIG. 40 (B) among the three positions H, I, J shown in FIG. 38 and FIG. 39 (B). , The I position which is the foremost position.

  Also, as described above, when the first slide member 320 is advanced, the actuator 336 of the first electric switch 335 is disengaged from the projection member 337 attached to the first slide member 320, thereby causing the first electric switch 335 to The generated signal causes the controller described above to de-energize the solenoid 326.

  The deenergization of the solenoid 326 causes the plunger 327 to move out of the solenoid 326 by the spring force of the spring 328, and the bending lever member 329 by the spring force of the spring 331 with the U in FIG. 39 (B) centered on the central shaft 329A. Rotate in the direction. At this time, the first slide member 320 is advanced to the movement limit where the front end of the first slide member 320 reaches the I position, so the roller 330 of the bending lever member 329 is shown in FIG. As described above, it strikes the aforementioned inclined surface 320C of the first slide member 320. For this reason, the pivoting of the bending lever member 329 in the U direction about the central axis 329A is stopped halfway.

  As described above, when the first slide member 320 advances, the actuating member 322 shown in FIG. 25 provided at the front end of the first slide member 320 is the lever member 31 of the opening / closing machine 13 via the actuated member 323. The first portion 31A is pressed in the direction A in FIG. Therefore, as described above, the first portion 31A swings in the A direction with the second bent portion 31D of the lever member 31 as a fulcrum, whereby the brake shaft 21 and the brake drum 22 of the brake device 19 of the opening / closing device 13 Slides in the A ′ direction, which is the same direction as the A direction, whereby the brake device 19 which has been on so far is turned off. For this reason, the shutter curtain 1, which has stopped at the halfway position in the fully open or open / close movement direction, is directed downward while rotating the above-mentioned take-up shaft 11 by its own weight such as the seat plate 201B in the lower part of the take-up shaft 11. The drive shaft 14 of the opening and closing machine 13 is also freely rotated via the driving force transmitting means 12 and the shutter curtain 1 is fully closed. It will be done.

  When a person finds that a disaster such as a fire has occurred, this person is disposed in the operation device 230 shown in FIG. 23, and is connected to the end of the second control wire 112 described above. The second control wire 112 is pulled and operated by a manual operation member such as a lever member. The other end of the second control wire 112 is connected to the above-described raising and lowering member 341 as described in FIG. 39B, so that the second control wire 112 is pulled. The raising and lowering member 341 tilts to the side of the solenoid 326 about the central axis 342A, and the tip member 340 and the plunger 327 retract due to the pressing action of the raising and lowering member 341. Thereby, even before the solenoid 326 is energized and excited, the bending lever member 329 is pressed by the pressing force from the raising and lowering member 341 via the tip member 340 as when the solenoid 326 is energized and excited. 39B, the roller 330 of the bending lever member 329 escapes from the recess 320B of the first slide member 320 so that the first slide member 320 is of the spring 321. It will move forward with spring force.

  For this reason, the shutter curtain 1 is fully closed also by operating a manual operation member such as a lever member connected to the end of the second control wire 112, and the shutter curtain 1 forms a disaster prevention section. Can.

  As described above, when the first slide member 320 moves to the forward limit, the connecting portion 338A provided on the connecting member 338 of the first slide member 320 is shown in FIGS. 40A and 41A. As shown in FIG. 5, the above-mentioned stepped surface 410B of the second slide member 410 abuts or approaches this stepped surface 410B. Therefore, even if the first slide member 320 moves to the forward limit shown in FIGS. 40 (B) and 41 (B), the second slide member 410 is shown in FIGS. 40 (A) and 41 (A). As it has been, it has stopped at the position shown in FIG. 39 (A). Therefore, the second slide member 410 is configured as a component, and the intermediate device 400 shown in FIGS. 40 (A) and 41 (A) maintains the same state as in FIG. 39 (A). Do.

  As described above, when the shutter curtain 1 reaches the fully closed position and a disaster such as a fire is eliminated, the shutter curtain 1 is disposed in the operation device 230 and is connected to the end of the third control wire 313 described above. The third control wire 313 is pulled and operated by a manual operation member such as a lever member. Thus, the third control wire 313 is connected to the connection portion 338A of the connection member 338 of the first slide member 320, so that the first slide member 320 retracts against the spring force of the spring 321. become. Therefore, the first slide member 320 retracts from the position shown in FIG. 41 (B) to the initial position where the front end of the first slide member 320 becomes the H position in FIGS. 38 and 39 (B). It will be. Further, when the first slide member 320 returns to this initial position, the bending lever member 329 pivots in the U direction of FIG. 39 (B) by the spring force of the spring 331 about the central shaft 329A. The roller 330 of the member 329 is fitted in the recess 320B of the first slide member 320, whereby the first slide member 320 on which the spring force of the spring 321 acts is the front end of the first slide member 320. Reaches H position and stops. Thereby, the automatic closing device 232 returns to the initial state before a disaster such as a fire occurs.

  When the third control wire 313 is pulled by a manual operation member such as a lever as described above, the connecting portion 338A of the connecting member 338 is brought into contact with the bracket 403 shown in FIG. Thus, when the third control wire 313 is pulled by an excessive operating force by a manual operation member such as a lever member, the excessive operating force acts on the connecting member 338 and the first slide member 320 as a bracket. You may make it prevent by 403.

  As described above, when the first slide member 320 returns to the initial position, the brake shaft 21 and the brake drum 22 of the brake device 19 of the opening / closing device 13 move in the direction opposite to the A ′ direction by the spring 23 described above. Therefore, the brake device 19 returns from off to on. Thereafter, the shutter curtain 1 is opened and moved to the fully open position as described above by operating the above-mentioned "open" button provided on the operating device 230.

  In the shutter device after modification according to the present embodiment, the lock wire 236 and the first control wire 311 are the first string-like members, and the automatic closing device 232 is turned on by being pulled. A second control wire 112, which is a second string-like member, for manually turning the brake device 19 off is connected. Further, to the automatic closing device 232, a third control wire 313 which is a third string-like member for returning the automatic closing device 232 to an initial state by being pulled is connected.

  As described above, when the occurrence of a disaster such as a fire is detected by the aforementioned sensor or a person who finds the occurrence of a disaster such as a fire pulls the second control wire 112, the shutter curtain 1 becomes a disaster prevention section. When the shutter unit is moved to the fully closed position to form the shutter mechanism, the shutter device after refurbishment according to the present embodiment is the above-described shutter device for disaster prevention. On the other hand, as described above, when the shutter curtain 1 is opened and closed and the movement stop is performed by each button operation of "open", "close" and "stop" of the operation device 230, this embodiment is described. It is when the shutter apparatus after the said repair is the above-mentioned shutter apparatus for management.

  When the shutter device after refurbishment according to the present embodiment serves as the disaster prevention shutter device and the shutter curtain 1 is closing and moving, in other words, the automatic closing device 232 is in the state shown in FIG. When the intermediate device 400 is in the state shown in FIG. 41A and the shutter curtain 1 is in the closing movement, the obstacle 34 shown in FIG. When the shutter curtain 1 is in the middle of the closing movement, the curtain sub-portion 271B disposed at the end of the shutter curtain 1 on the closing side is, in other words, the seat plate 201B of the shutter curtain 1. The movable portion 270B of FIG. 26 forming the lower portion comes in contact with the obstacle 34, and the descent of the movable portion 270B is stopped.

  Even if the descent of the movable portion 270B is stopped, the aforementioned curtain main portion 71A, which is constituted by the curtain main body 1A and the fixed portion 270A of FIG. 26 in the seat plate 201B, descends from the state of FIG. Due to the relative rise of the curtain sub-portion 271B (the movable portion 270B) with respect to the curtain main portion 71A caused by this descent, as shown in FIG. 27, the swinging member 281 disposed inside the fixed portion 270A becomes It swings upward about the fulcrum shaft 280. As a result, the lock member 250 constituting the above-described mechanical coupling device 255 is rotated in the X direction in FIG. 30 by the pressing member 254 provided on the swinging member 281, so that the state of FIG. The toothed portion 253 of the locking member 250 engages with the toothed portion 235A of the rotating member 235.

  As a result, the rotating member 235 and the take-up reel 237 rotating in the Y direction in FIG. 30 can not rotate in the Y direction when the shutter curtain 1 is in the closing movement, that is, the rotating member 235 and the winding The reel 237 can not rotate, and the shutter curtain 1 and the lock wire 236 fed from the take-up reel 237 are connected by the mechanical connecting device 255 having the rotating member 235 and the locking member 250 as components. become. Therefore, the weight of the shutter curtain 1 excluding the movable portion 270B, that is, a downward tension due to the weight of the curtain main portion 71A acts on the lock wire 236.

  As described above, the shutter curtain 1 moving in the closing direction abuts against the obstacle 34, and after the downward tension by the weight of the shutter curtain 1 excluding the movable portion 270B acts on the lock wire 236 When the obstacle 34 is dented and deformed, the lock wire 236 coupled to the shutter curtain 1 by the mechanical coupling device 255 is pulled downward by this dented portion.

  In addition, even if the obstacle 34 is a hard object that is not deformed or hardly dented, it is shown in FIG. 35 when the lock member 250 is rotated in the X direction of FIG. 30 by the pressing member 254 of the rocking member 281. Thus, among the first teeth 253A, the second teeth 253B, and the third teeth 253C provided as the teeth 253 on the lock member 250, the first teeth 253A are first teeth of the rotation member 235. The second teeth 253B and the third teeth 253C engage with the teeth 235A of the rotating member 235. Of these engagements, at least engagement of the first teeth 253A with the teeth 235A is, as shown in FIG. Of the first lock member side contact portion 259A and the second lock member side contact portion 259B provided as two member side contact portions 259, from the shaft 256 serving as the rotation center axis of the lock member 250 The first lock member side contact portion 259A at a distant place is pushed up by the pressing member 254 which is the shutter curtain side contact portion 258.

  The distance between the first tooth 253A, the second tooth 253B, and the third tooth 253C is the same as the distance (tooth pitch) between the teeth 235A formed on the rotating member 235 at equal intervals. Alternatively, they have substantially the same size, or a size that is an integral multiple of 2 or more or a size that is approximately an integer multiple of the interval size of the teeth 235A. Therefore, when the first teeth 253A engage with the teeth 235A, the second teeth 253B and the third teeth 253C also engage with the teeth 235A.

  Further, when the first lock member side contact portion 259A is pushed up by the pressing member 254 as described above, next, as shown in FIG. 31, the second lock member side contact portion 259B of the lock member 250. Makes contact with the pressing member 254, and the second lock member side contact portion 259B is pushed up. That is, pushing up of the lock member side contact portion 259 of the lock member 250 by the pressing member 254 is performed by transitioning from the first lock member side contact portion 259A to the second lock member side contact portion 259B. This push will be done.

  Therefore, the rotation of the lock member 250 in the X direction shown in FIG. 30 is continued in two steps, whereby the first tooth portion 253A of the lock member 250 is rotated by the rotating member 235. The second teeth 253B and the third teeth 253C continue the engagement with the teeth 235A of the rotating member 235 even when the teeth 235A and the teeth 235A of the second gear 253B are not engaged. The toothed portion 253C slightly rotates the rotating member 235 in the Z direction of FIG. The rotation in the Z direction is a rotation in a direction in which the take-up reel 237 winds the lock wire 236, and is a direction in which the lock wire 236 is pulled downward.

  And in this manner, the second tooth portion 253B and the third tooth portion 253C rotate the rotation member 235 in the Z direction in such a manner that the distance from the shaft 256, which is the rotation center of the lock member 250, is the first lock. Since the second lock member side contact portion 259B, which is shorter than the member side contact portion 259A, is pushed up by the pressing member 254, in the Z direction of the rotation member 235 by the second tooth portion 253B and the third tooth portion 253C. The amount of rotation increases. Therefore, even if the relative amount of rise of the curtain sub-portion 271B with respect to the curtain main portion 71A when the shutter curtain 1 in closing movement abuts against the obstacle 34 is a case where the obstacle 34 is dented and deformed Similarly to the above, the amount of pulling downward of the lock wire 236 can be sufficiently secured.

  For this reason, even when the obstacle 34 is a hard one that hardly or hardly dents, the lock wire 236 coupled to the shutter curtain 1 by the mechanical coupling device 255 is deformed when the obstacle 34 is dented. As such, it can be pulled sufficiently downward.

  In the present embodiment, the number of teeth 253 provided on the lock member 250 is three, but the number may be four or more.

  In addition, when the shutter curtain 1 contacts the obstacle 34, the first lock member side contact portion 259A of the lock member 250 is pushed up by the pressing member 254 which is the shutter curtain side contact portion 258 as described above. As a result, the first tooth portion 253A of the lock member 250, which rotates in the X direction about the shaft 256 in FIG. 30, tries to engage with the tooth portion 235A of the rotation member 235. By the rotation timing of the rotation member 235, the tip of the first tooth portion 253A abuts on the tip of the tooth portion 235A, whereby the lock member 250 and the rotation member 235 are in a butting state, and these lock members As a result, there is a risk that the rotational members 250 and 250 may be in a deadlock state.

  However, in the present embodiment, as described in FIG. 35, the lock member 250 and the shaft 256 serving as the rotation center axis of the lock member 250 are rotated by the elongated holes 267 formed in the case 233 described above. The member 235 is movable toward and away from the member 235, and is always urged in the AA direction, which is the rotating member 235, by the elastic biasing force of the torsion coil spring 257 which is an elastic member. When a deadlock condition occurs, the lock member 250 and the shaft 256 slightly move in the direction of retracting from the rotation member 235 by the reaction force from the rotation member 235, and the deadlock state is eliminated, and a torsion coil spring The elastic force of 257 advances to the rotating member 235 side, whereby the first tooth portion 253A of the locking member 250 continues to rotate. It will engage the teeth 235A of the timber 235.

  For this reason, according to the present embodiment, the end of the first tooth portion 253A of the lock member 250 and the end of the tooth portion 235A of the rotation member 235 abut each other, causing the lock member 250 and the rotation member 235 to be in a deadlock state This can be avoided, and an excessive load generated on the lock member 250 and the like when this deadlock condition occurs can be eliminated.

  Further, in the present embodiment, since the first lock member side contact portion 259A provided in the lock member 250 is an elastic portion by the plate spring 260, the above-mentioned deadlock state occurs. Since the elastic member is elastically deformed by the reaction force from the rotation member 235, the lock member 250 rotates in the X direction after being slightly rotated in the W direction of FIG. This can also eliminate the deadlock condition.

  As described above, when the shutter curtain 1 in closing movement abuts against the obstacle 34 and the lock wire 236 is pulled downward, the tension of the lock wire 236 is connected via the connecting member 294 shown in FIG. It acts on the first control wire 311, and this first control wire 311 is also pulled.

  When the first control wire 311 is pulled, the other end of the first control wire 311 is a component of the intermediate device 400 in the state of FIG. 41A as described above. Since it is connected to the first pivoting member 401, the first pivoting member 401 pivots in the direction P in FIG. 39A, and the cam portion 401C of the first pivoting member 401 is rotated by this pivoting. The second pivoting member 402 whose convex portion 408 is in contact with the side surface 401D of the second pivoting member pivots in the direction T in FIG. 39 (A). Thereby, the second slide member 410 in which the convex portion 411 of the second rotation member 402 is inserted into the opening hole 410A is shown in FIG. 42A by the pressing force from the convex portion 411. , Retract against the spring force of the spring 412.

  As a result, the second slide member 410 presses the connecting portion 338A of the connecting member 338 of the first slide member 320 by the step surface 410B. Therefore, the first slide member 320 is also retracted, and the retraction is caused by this retraction. The aforementioned braking device 19 switches from off to on. For this reason, the shutter curtain 1 in contact with the obstacle 34 of FIG. 23 during the closing movement stops the closing movement. The state of the automatic closing device 232 at this time is shown in FIG. 42B, and the position of the front end of the first slide member 320 at this time is the J position shown in FIGS. 38 and 39.

  Further, as described above, when the first control wire 311 is pulled, the step surface 410B of the second slide member 410 to be retracted is pressed by the connection portion 338A of the connection member 338 of the first slide member 320. Since the first slide member 320 is retracted, the step surface 410B is a pressing portion of the second slide member 410 for pressing the first slide member 320, and the connecting portion 338A is a pressure from the second slide member 410. It becomes a pressed portion of the first slide member 320 for receiving pressure.

  Further, in the above-described operation, when the second rotation member 402 rotates in the T direction of FIG. 39A as described above, the pinion gear 500B of the delay device 500 rotates in the R direction. When the pinion gear 500B rotates, as described above, the disconnecting action of the one-way clutch of the delay device 500 functions, so the pinion gear 500B rotates at high speed in the R direction, and the second pivoting member 402 also moves in the T direction. It can rotate at high speed. In other words, no delay action occurs in the delay device 500 at this time.

  Further, as described above, when the first control wire 311 is pulled, the first pivoting member 401 pivots in the P direction of FIG. 39A, and the second pivoting member 402 pivots in the T direction. Since the motion performed by the first and second pivoting members 401 and 402 is a pivoting motion when the first control wire 311 is pulled, even if the length of the first control wire 311 is elongated, The entire pivoting amount of the first pivoting member 401 is not transmitted to the second pivoting member 402.

  That is, in the present embodiment, as described above, the three teeth 253A, 253B, 253C are provided on the lock member 250 in consideration of the case where the obstacle 34 is not deformed in a dent or hard in a small dent deformation. Even if the length by which the first control wire 311 is pulled is increased by the action of the tooth portions 253A, 253B, 253C, the first rotation of the total amount of rotation of the first rotation member 401 is provided. Only when the side surface 401 D of the cam portion 401 C of the member 401 is in contact with the convex portion 408 of the second rotation member 402, the second rotation member 402 rotates the first rotation member 401 in the P direction. It is transmitted as rotation of the second rotation member 402 in the T direction. Then, even if the first pivoting member 401 pivots in the P direction after the side surface 401D of the cam portion 401C of the first pivoting member 401 is not in contact with the convex portion 408 of the second pivoting member 402, The rotation is, so to speak, an idle rotation, and the second rotating member 402 is stopped when the first rotating member 401 is performing the idle rotation.

  For this reason, even if the length by which the first control wire 311 is pulled is long and the amount of rotation of the first rotation member 401 is large, the distance by which the first slide member 320 retracts does not increase. Thereby, when the shutter curtain 1 in closing movement abuts against the obstacle 34, the front end of the first slide member 320 is shown in FIG. As shown in FIG. 38 and FIG. 39 (B), among the three positions I, J and H shown in FIG. This J position is a position on the front side of the H position which is the initial position, and is a position where the brake device 19 can be mechanically switched from off to on by the first slide member 320, as shown in FIG. The roller 330 of the bending lever member 329, which is shown in Fig. 41B, is a position maintaining the state of being released from the recess 320B of the first slide member 320, as in Fig. 41B. The maintenance of the state where the roller 330 escapes from the recess 320B is shown in FIG. 42 (B) showing that the shutter curtain 1 in the closing movement abuts against the obstacle 34. ing.

  As can be understood from the above description, after the shutter curtain 1 is closed due to the occurrence of a fire or the like and started to move, the shutter device according to the present embodiment is installed due to a fire or the like or other reasons. Even if the building loses power, the first slide member 320 of the automatic closing device 232 switches the braking device 19 of the opening / closing machine 13 from off to on when the shutter curtain 1 abuts against the obstacle 34 during closing movement. Thus, the shutter curtain 1 can be mechanically stopped without using electricity.

  As described above, when the obstacle 34 is removed after the above-mentioned brake device 19 is switched from off to on and the shutter curtain 1 in closing movement is stopped, the curtain sub-portion 271B of the shutter curtain 1 is In order to descend, the connection between the shutter curtain 1 and the lock wire 236 by the mechanical connection device 255 is released. As a result, since the tension force acting on the lock wire 236 and the first control wire 311 disappears, the first pivoting member 401 is pivoted by the spring 405 in the O direction in FIG. 39A. The second pivoting member 402 is pivoted in the direction S in FIG. 39 (A) by the second slide member 410 being advanced by the spring 412, and the second sliding member 410 is advanced by the automatic closing device. The first slide member 320 moves forward by moving the position of the front end from the position J of FIG. 42B to the position I shown in FIGS. 38 and 39B by the spring force of the spring 321. For this reason, the brake device 19 of the opening and closing machine 13 is mechanically switched from on to off again, and the shutter curtain 1 closes and resumes the movement.

  Further, at this time, the second rotation member 402 rotates in the S direction of FIG. 39A, whereby the pinion gear 500B of the delay device 500 rotates in the Q direction, and the Q direction of the pinion gear 500B. As for the rotation, as described above, in the delay device 500 which is a rotary type damper, a resisting force by the viscous fluid is generated. Therefore, the position of the front end of the first slide member 320 is shifted from the position J of FIG. 42 (B) to the position I of FIGS. 38 and 39 (B), and the shift device 19 of the open / close machine 13 by this shift. Is not instantaneously performed because of the delay action of the delay device 500, and this switching timing is delayed. Therefore, the shutter curtain 1 closing and resuming movement due to the removal of the obstacle 34 is started with a time delay from the removal of the obstacle 34. Therefore, the task of removing the obstacle 34 takes time. It can be carried out.

  In the above, the distance by which the first slide member 320 retracts when the closing shutter curtain 1 abuts against the obstacle 34 is such that the front end of the first slide member 320 is positioned rearward of the J position If the distance is long, the roller 330 of the bending lever member 329 will fit in the recess 320 B of the first slide member 320. When such a situation occurs, the first slide member 320 is braked by the stopper action of the roller 330 even if the obstacle 34 with which the shutter curtain 1 in the closing movement is abutted is removed. The forward end can not be advanced to reach the I position where it can switch from on to off.

  That is, in the operable range of the first slide member 320 of the automatic closing device 232 serving as a switching member for switching the braking device 19 on and off, there is a range in which the braking device 19 can not be switched off from on. It will be.

  However, according to the present embodiment, as is apparent from the above, the first pivoting member 401 which is the abutting member on the side of the first control wire 311 and the first sliding member 320 of the automatic closing device 232. The second pivoting member 402, which is the abutted member on the side, is a member that pivots about the central axes 401A and 202A, and therefore, of the total pivoting amount of the first pivoting member 401, Only part of the amount of rotation is transmitted to the second pivoting member 402, so that the distance by which the first slide member 320 retracts when the closing shutter curtain 1 abuts against the obstacle 34. Is not a long distance where the front end of the first slide member 320 is positioned behind the J position. For this reason, the first slide member 320 can be stopped at a backward distance at which the position of the front end becomes the J position, whereby after the obstacle 34 against which the shutter curtain 1 in closing movement has abutted is removed, It is possible to switch the brake device 19 from on to off.

  For this reason, according to the present embodiment, the first rotation member 401, the second rotation member 402, and the like constitute the operation range restriction means 430 that does not operate the first slide member 320 to the above-mentioned unchangeable range. It will be.

  And in this embodiment, the locking member 250 which is a constituent member of the mechanical coupling device 255 shown in FIG. 30 and FIG. 31 has the tooth portion 253 of the locking member 250 as described in FIG. Since the gap adjusting means 266 is provided for adjusting the size of the gap 265 between the front end of the rotary member 235 and the front end of the tooth portion 235A of the rotation member 235, the shutter curtain 1 is not in contact with an obstacle At times, the size of the gap 265 can be set to an appropriate value. Therefore, a problem occurs when the size of the gap 265 is larger than the appropriate value, that is, when the shutter curtain 1 in the closing movement abuts against the obstacle 34, the teeth of the locking member 250 are immediately It is possible to solve the problem that it becomes difficult to stop the shutter curtain 1 instantaneously because obstacle detection is delayed by the fact that 253 does not engage with the rotation member 235 tooth portion 235A, and the clearance at the normal time is also eliminated. The problem that occurs when the size of 265 is smaller than the appropriate value, that is, even when the shutter curtain 1 is not in contact with the obstacle 34, for example, when the rotating member 235 or the locking member 250 vibrates It is possible to solve the problem that the portion 253 contacts or engages with the tooth portion 235A.

  The first control wire 311, the second control wire 112, and the third control wire 313 described above are respectively the first string-like member and the second string-like member in the shutter device after refurbishment according to the present embodiment. It becomes a member and the 3rd string-like member.

  The above description has been made when the shutter device after refurbishment according to the present embodiment is the above-described shutter device for disaster prevention. When the shutter device is the aforementioned management shutter device, that is, when the shutter curtain 1 is closed and moved by the operation of the operation device 230 described above, the shutter curtain 1 is in contact with the obstacle 34 At the same time, since tension and tension act on the first control wire 311, the first pivoting member 401 of the intermediate device 400 pivots in the P direction of FIG. Although the second slide member 410 is retracted via the second pivoting member 402, the first slide member 320 at this time is retracted to the retraction limit where the position of the front end is the H position. As shown in 39 (A), there is a large space between the step surface 410B of the second slide member 410 and the connection portion 338A of the connection member 338 of the first slide member 320, and therefore, Even if the second slide member 410 is retracted, the retraction does not affect the first slide member 320.

  In other words, when the modified shutter device according to the present embodiment is the management shutter device, the first slide member 320 is a component even if the closing shutter curtain 1 is in contact with the obstacle 34. The automatic closing device 232 does not operate, and the automatic closing device 232 maintains the state shown in FIG. 39 (B).

  And in this embodiment, when the shutter device after refurbishment is a shutter device for management, the shutter curtain 1 in closing movement is in contact with an obstacle, and the tension force or the pulling force of the first control wire 311 Thus, when the first rotation member 401 of the intermediate device 400 rotates in the P direction, the actuator 421 of the second electric switch 420 described above performs an operation of disengaging from the projection member 422 of the first rotation member 401. The control device 27 of FIG. 23 electrically drives and controls the electric motor device 18 of the opening / closing device 13 and the brake device 19 in response to a signal from the second electric switch 420, whereby the shutter curtain 1 contacts an obstacle. A reverse rise is carried out to open and stop from the position to a predetermined height position. That is, the shutter curtain 1 of the management shutter device opens and moves to a height position away from the obstacle and stops after coming into contact with the obstacle.

  As described above, the shutter device after refurbishment according to the present embodiment has a function as a management shutter device and a function as disaster prevention shutter device, as in the shutter device before refurbishment according to the above-described embodiment. Having both functions, the delay device 500 is only for the function as the disaster prevention shutter device.

  Further, in the shutter device after refurbishment according to the present embodiment, when the shutter device functions as a management shutter device, the detection device is a detection unit that detects that tension force is applied to the lock wire 236. A two-electric switch means 420 is provided, this second electric switch means being provided in the intermediate device 400 in the vicinity of the delay device 500.

  As described above, the lock wire 36 is folded at the both ends thereof by the mechanical coupling device 39 attached to the seat plate 1B while being coupled to the first processing device 37 and the second processing device 38. Since it is U-shaped, when the seat plate 1B is removed from the curtain main body 1A, the seat plate 1B, the first processing device 37, and the second processing device 38 are connected via the lock wire 36. It is in a state of
