An embodiment of the present invention will be described below. FIG. 1 is a longitudinal sectional view showing a storage box portion of a panel shutter according to an embodiment of the present invention, and FIG. 2 is a schematic perspective view of a panel drive system of FIG. In the drawing, reference numeral 1 denotes a pair of left and right guide rails, and these guide rails 1 are composed of vertical guide rails arranged upright on both sides of a so-called shutter opening / closing opening such as a doorway of a building or a window. Reference numeral 2 denotes a panel for raising and lowering the space between the two guide rails 1. The panel 2 includes a panel holding frame 2a having a front rectangular frame shape as shown in FIGS. And a panel face plate 2b attached to the panel holding frame 2a. As shown in FIGS. 2 to 4, pins (supporting shafts) 21 projecting outward from both end surfaces of the panel 2 are provided on both upper sides of the panel 2 so as to be movable in the thrust direction. . More specifically, a pin bracket 26 is provided on both upper side surfaces of the panel 2 as shown in FIGS.
1 is inserted movably in the thrust direction, and the pin 21 is
7. The pin 21 is rotatably inserted and connected to a panel connecting chain (roller chain) 3. In this way, the plurality of panels 2 that move up and down and open and close between the two guide rails 1 are connected in series by the panel connection chain 3 outside the both side end surfaces of each panel 2 via the respective pins 21. . On the pins 21 of each panel 2, a suspending roller 25 located outside the panel connecting chain 3 is rotatably mounted. Further, panel rollers 2 are provided on both lower sides of each panel 2 via shafts 23.
2 is rotatably mounted. Reference numeral 5 denotes a storage box (panel storage section) disposed above the guide rail 1. The storage box 5 has brackets 5a on both left and right sides, and both guide rails 1 are provided inside the bracket 5a. A pair of left and right panel driving sprockets 8 are pivotally supported, and the panel linking chain 3 is meshed with these panel driving sprockets 8. Reference numeral 4 denotes a storage rail disposed inside the bracket 5a. The storage rail 4 is located above a horizontal line passing through the axis of the panel driving sprocket 8 and within the radius of the panel driving sprocket 8. In the example shown in the drawing, the panel storage direction side gradually and gradually descends and slopes down, and the panel drive sprocket 8 extends in the lateral direction from between the bracket 5a and the panel drive sprocket 8 in the panel storage direction side. Is rotatably supported on the suspension roller 25 of the panel 2 that has passed through the panel storage direction. Therefore, the front end side of the storage rail 4 intervenes between the bracket 5a and the panel driving sprocket 8, and overlaps with a cylindrical area having a cross section of the rotation circular locus of the panel driving sprocket 8. ing. The storage rail 4 has a mounting surface for the bracket 5a and a rolling surface of the suspension roller 25, and a space is formed below the rolling surface.
The rotation axis of the panel driving sprocket 8 is spaced apart from the rotation axis of the panel driving sprocket 8, and the outer periphery of the panel driving sprocket 8 around the axis corresponding to the movement locus of the suspension roller 25 according to the chain feed direction of the panel driving sprocket 8. In the region, the upper end of the guide rail 1 and the front end of the storage rail 4 are separated from each other to form a space region without a rail. Further, the lower end of the storage rail 4 inclined as described above is interrupted at a near position separated from the depth end in the storage box 5 by a distance corresponding to the installation space of the switchgear 13. A stopper 4a (FIG. 1) for preventing the suspension roller 25 that has rolled on the storage rail 4 from falling off is provided at the lower end of the storage rail 4.
Reference). In the above, the series of panels 2 is moved vertically along the guide rails 1 by the feed operation of the panel linking chain 3 by forward and reverse rotation of the panel driving sprockets 8 and along the storage rails 4. It is to be transferred to the horizontal movement of the parallel posture. In the parallel posture of the panels 2, the panel linking chain 3 between the panels 2 hangs inside the storage rail 4. Reference numeral 6 denotes a chain tip guiding device provided on the bracket 5a.
Consists of a chain tip guide rod mounted inside the bracket 5a. This chain tip guide rod 6
Are effectively disposed by utilizing an upper space between both end surfaces of the panel 2 suspended on the storage rail 4 and the bracket 5a. 4 are arranged in parallel. The chain tip guide rod 6 includes:
A free end portion (end side link portion) 3a of the panel linking chain 3, which meshes with the panel driving sprocket 8 and extends in the panel storage direction, is movably moored. As a result, the free end 3a of the panel linking chain 3 moves along the chain leading guide bar 6 when the panel 2 is moved up and down, and first moves onto the storage rail 4 during the panel storing operation. Pin 2 of panel 2
The length from 1 to the free end 3a of the panel connecting chain 3 can be reduced. Therefore, the free end side of the panel linking chain 3 does not loosen greatly when the panel is stored, and the panel linking chain 3 during the panel elevating operation.
Entanglement can be reliably prevented. Further, since the free end 3a of the panel linking chain 3 is always moored to the chain tip guide rod 6 as described above, the panel linking chain 3 is extended when the panel is extended.
Does not come off from the panel driving sprocket 8 and safety and reliability are greatly improved. Further, as described above, the chain leading guide bar 6 disposed above the storage rail 4 is provided with a panel connecting chain 3 that connects the panels 2 in a parallel posture suspended on the storage rail 4 and has a U-shape. Since it does not become an obstacle when bending and hanging in the shape of a letter, there is no need to provide extra space for arranging the chain tip guide bar 6 in the storage box 5, and therefore a compact receiving structure can be achieved. On the other hand, on the side near the upper end of the guide rail 1 extending into the storage box 5, it is located near the lower part of the guide sprocket 8 and electrically senses abnormal bending (slack) of the panel linking chain 3. A chain slack detecting device 7 is provided. In the vicinity of the panel driving sprocket 8, the panel connecting chain 3 which moves up and down along the guide rail 1 is brought into contact with the panel driving chain 3 in a predetermined moving direction from the panel driving sprocket 8. And chain guide members 9 and 10 for guiding the panel linking chain 3 in contact with the panel driving sprocket 8 in a predetermined meshing direction. More specifically, it is arranged on the storage rail 4 side in the vicinity of the panel driving sprocket 8, is located in the movement path of the panel connecting chain 3 entering and exiting the storage box 5, and contacts the panel connecting chain 3. And a panel storage side chain guide member 9 formed so as to be able to guide the panel linking chain 3 in the meshing direction, the mesh release direction and the storage rail 4 direction, and the guide rail 1 side near the upper end side of the guide rail 1. Is located in the movement path of the panel linking chain 3 that moves up and down, and comes into contact with the panel linking chain 3 so that the panel linking chain 3 can be guided in contact with the meshing direction, the meshing releasing direction, and the guide rail 1 direction. The formed panel entrance-side chain guide member 10
A chain / sprocket guiding device is constituted by at least one of the above. A panel guide 11 is provided near the panel entrance of the storage box 5 for smoothly guiding the panel roller 22 below each panel 2 in the panel storage direction and the panel extension direction. Next, a description will be given of a panel shutter driving device configured as described above. First, as described above, the lower end portion (rear end portion) of the storage rail 4 is interrupted at a front position separated from the depth end of the storage box 5 by a distance corresponding to the installation space of the switchgear 13. The switchgear 13 is arranged by utilizing a depth space area in the storage box 5 where does not extend. Here, the switchgear 13 has a mounting base 13a integrally as shown in FIG.
At the upper and lower portions on both sides, a long slot 13b for mounting is provided which is long in the vertical direction. The switchgear 13 is attached to the bracket 5a on one side in the inner space area in the storage box 5. In this case, the mounting base 13a is fixed to the bracket 5a by inserting a bolt 28 into the long hole 13b of the mounting base 13a of the switchgear 13 and screwing and tightening a nut 29 to the bolt 28. Therefore, if the nut 29 is loosened, the slot 1
The mounting position of the switchgear 13 can be adjusted vertically by an amount corresponding to the length of 3b. The switchgear 13 has an output sprocket 130 as shown in FIG.
To the interlocking sprocket 14 via the interlocking chain 15
Are linked. The interlocking sprocket 14 is provided with
3 is fitted to one end of a driving-side rotating shaft 16 disposed at a position above and spaced apart from the other end of the driving-side rotating shaft 16. Is being worn. The driving-side rotating shaft 16 is provided in FIG. 1 and FIG.
As shown in the figure, the left and right brackets 5a are rotatably supported via bearings 30. Here, the bearing body 3
As shown in FIG. 1, reference numeral 0 denotes a notch 5b provided in the bracket 5a, which is fitted and mounted so as to be position-adjustable. Therefore, the distance between the driving side rotating shaft 16 and the panel driving sprocket 8 can be adjusted. Both ends of the driving side rotating shaft 16 project outside the left and right brackets 5a via the bearing body 30, and a first transmission sprocket 17 is fitted to the outside projecting end. On the other hand, as described above, the driven-side rotating shaft (sprocket shaft) of the panel driving sprocket 8 which is supported at a position above the guide rail 1 in the left and right brackets 5a.
As shown in FIG. 2, the projection 20 projects outside the left and right brackets 5 a via the bearing 31, and the second transmission sprocket 18 is fitted to the outside projection end. The endless transmission chain 1 is attached to the first transmission sprocket 17 and the second transmission sprocket 18.
As a result, the rotation output of the switch 13 is transmitted to the left and right panel driving sprockets 8, and the panel driving sprocket 8 is driven to rotate. Therefore, the panel driving sprocket 8 and the interlocking sprocket 14 are arranged inside the bracket 5a, and the first transmission sprocket 17, the second transmission sprocket 18 and the transmission chain 19 are arranged outside the bracket 5b. In the above description, the side piece 5c is formed on one side of the bracket 5a (the left side in FIGS. 1 and 2) along the guide rail 1 so as to be parallel to the guide rail 1. It can be a bracket mounting support for mounting and fixing to a building or the like. As described above, the side piece 5c of the bracket 5a
Is used as the bracket mounting support 5c, the driven-side rotary shaft 20 that supports the panel weight, which is a dynamic load when the panel is raised and lowered, can be arranged at a position closest to the bracket mounting support 5c. Accordingly, the storage rail 4 that supports the panel load, which is a static load in the panel storage state, can be disposed at a position farther from the bracket mounting support portion 5c than the driven-side rotary shaft 20. As described above, the driven rotary shaft 20 for supporting the dynamic load when the panel is raised and lowered is arranged at the position closest to the bracket mounting support portion 5c, and the storage rail 4 for supporting the static load when the panel is stored is mounted on the bracket. By arranging the storage box 5 at a position farther than the support portion 5c, the strength of the entire storage box 5 including the bracket 5a is advantageous. In the storage box 5, the guide rail 1 is a panel elevating unit, the storage rail 4 is a panel storage unit, and a system of the switch 13 and the driving side rotary shaft 16 is a driving mechanism. The panel elevating unit and the panel storage unit are arranged in a space sandwiched between the unit and the bracket mounting support 5c. The drive mechanism (storage box 5)
In the back space region of the figure), the driving side rotating shaft 16 and the interlocking sprocket 14 are located above the opening / closing device 13, and the opening / closing unit 13 and the driving side rotation shaft 16 and the interlocking sprocket 14 are accommodated in the storage space. It is arranged in a direction substantially parallel to the panel 2 at the storage position suspended by the rail 4. With this arrangement, the storage box 5
The power transmission sprockets (the interlocking sprocket 14 and the first
The installation space for the transmission sprocket 17) can be minimized. Therefore, the installation space does not need to be particularly large, and the switchgear 13 can be stored in the storage box 5.
The installation space for the storage box 5 is reduced as compared with the case where the storage box 5 is externally mounted, and the restrictions on the installation work can be greatly eased. Next, the operation will be described. When the switch 13 is activated in the shutter opening direction, the rotational driving force is
The sprocket 14 is transmitted from the output sprocket 130 via the interlocking chain 15 to the interlocking sprocket 14 → the main drive side rotating shaft 16 → the first transmission sprocket 17 → the transmission chain 19 → the second transmission sprocket 18 → the driven side rotation shaft 20. 8 is driven to rotate clockwise in FIG. Thus, the panel driving sprocket 8
The panel 2 between the guide rails 1 is lifted up via the roller chain 3 meshed with. When the upper end of the panel 2 reaches the panel driving sprocket 8 by the lifting, the upper end of the panel 2 moves circularly along the pitch circumference of the panel driving sprocket 8 together with the panel linking chain 3, and moves in the direction of the storage rail 4. It is guided to move. At this time, the panel roller 2 below the panel 2
2 is guided obliquely upward by the inclined guide portion 11a of the panel guide 11 and advances in the storage box 5 in the depth direction (panel storage direction). In this way, the upper end of the panel 2 that has moved up between the two guide rails 1 moves along the tip of the panel driving sprocket 8 toward the storage rail 4 (panel storage direction). When the panel roller 22 is guided obliquely upward by the panel guide 11,
When the panel 2 passes through the panel driving sprocket 8 toward the panel storage direction, the panel 2 moves while maintaining the vertical posture in the state in which the lateral shake is prevented. After the panel 2 has passed through the panel driving sprocket 8 in the panel storage direction, the suspension rollers 25 on both upper sides of the panel 2 move onto the storage rail 4. At this time, the suspension roller 25 rolls on the storage rail 4 by its inclination, so that the panel 2 is automatically suspended inside the storage box 5 by the downward inclination along the storage rail 4 in the suspended state of the parallel posture. Go to When the suspension roller 25 of the panel 2 which has first moved onto the storage rail 4 reaches the inclined lower end of the storage rail 4, the suspension roller 25
Is a stopper 4 provided at the lower end of the storage rail 4.
a, and is prevented from falling off from the storage rail 4. In this way, after the first panel 2 arrives at the lower end of the storage rail 4, the subsequent panels 2 are sequentially fed, so that the panels 2 sequentially shifted to the storage rail 4 are adjacent to each other. It is suspended and stored in a parallel hanging state. In the above, the panel 2 is the guide rail 1
When the panel drive sprockets 8 are successively moved from the vertical movement in the series posture along the storage rail 4 to the horizontal movement in the parallel posture along the storage rail 4, the panel driving sprocket 8 first engages with the roller chain 3 to guide the engagement direction. Since the panel entrance / exit side chain guide member 10 that is extended as much as possible is arranged, the panel linking chain 3 is reliably guided to a predetermined position of the panel driving sprocket 8. Even if the panel connecting chain 3 and the panel driving sprocket 8 are abnormally meshed due to some unexpected action, the panel storage side chain guide member 9 is provided at the panel storage side where the meshing is completed. The panel linking chain 3 comes into contact with the panel storage side chain guide member 9 and is guided, so that the panel linking chain 3 is securely detached from the panel driving sprocket 8 and the panel 2 as described above. The storing operation is performed smoothly. Here, when the panel is stored, the panel linking chain 3 moves into the storage box 5 together with the first panel 2 without being entangled by the chain tip guide rod 6, and when the panel 2 is folded and stored, FIG. As shown by the dashed line (b), the panel 2 regularly hangs down along the side surface of each panel 2 in a U-shape. In this manner, when each panel 2 changes direction from the vertical movement in the vertical position along the guide rail 1 to the horizontal movement in the parallel position along the storage rail 4, the initial horizontal movement in the parallel position is performed. In the above, the panel connecting chain 3 connecting the preceding panel 2 and the succeeding panel 2 hangs down, but this hanging portion is guided downward along the side edge 9a of the panel storage side guiding member 9, so that the panel linking is performed. The hanging portion of the chain 3 can be reliably prevented from being entangled with and meshed with the panel driving sprocket 8, so that damage to the storage rail 4 and elevation of the panel 2 are not hindered. Further, an upper edge 9b is formed above the panel storage side chain guide member 9, and the upper edge 9b connects the tip of the storage rail 4 and the meshing position of the panel driving sprocket 8. , And guides the suspension roller 25 disposed on the tip of the pin 21 connected to the panel connecting chain 3 onto the storage rail 4. This series of operations is repeated each time the subsequent panel 2 reaches the vicinity of the storage rail 4. Next, the switchgear 13 is moved from the panel storage state.
When the panel drive sprocket 8 is rotated in the reverse direction, the panel drive sprocket 8 is rotated counterclockwise in FIG. 1 by the rotation output, so that the storage rail is connected via the panel linking chain 3 meshed with the panel drive sprocket 8. The upper panel 2 is sequentially pulled out in the feeding direction. In this case, the panel 2 on the storage rail 4 is
After passing through the panel driving sprocket 8 to the guide rail 1 side, it descends along the guide rail 1 to close the space between the two guide rails 1. At the time of such a panel extending operation, near the panel driving sprocket 8, first, the panel linking chain 3 is connected to the panel driving sprocket 8 by the side edge 9a and the upper edge 9b of the panel storage side chain guiding member 9. 8 is reliably guided to the predetermined meshing position. Further, the panel linking chain 3 is connected to the panel driving sprocket 8 by the other panel entrance / exit side chain guide member 10.
Leave smoothly from. In the process of raising and lowering the panel 2 as described above, if the panels 2 are folded or clogged in the guide rail 1, the panel 2 becomes a scandal in which the panel 2 cannot be moved. It is a factor of occurrence. However, in this case, the panel connecting chain 3
In this case, abnormal refraction occurs, and by detecting the extraordinary refraction by the chain slackness detecting device 7, it is possible to immediately cope with a scandal situation such as a major accident caused by folding or clogging of the panels 2 with each other. As described above, according to the present invention, the interlocking sprocket, which interlocks with the switch via the interlocking chain, and the panel linking chain, which links a plurality of panels in series, mesh with each other. A first driving sprocket coaxial with the interlocking sprocket, a second transmitting sprocket coaxial with the panel driving sprocket, and the first and second sprockets. Since the transmission sprocket and the transmission chain meshed and wound with each other are arranged outside the bracket, the first and second transmission sprockets and the transmission chain can be combined without considering the storage rail arranged inside the bracket. In addition to being able to be easily arranged, there is an effect that the storage box can be made to have a compact receiving structure.
