Description

The present invention relates to a steady rest device used for a folding door that has a simple structure, is easy to open and close, and has no play in a closed state or an open state.

  Folding doors can be opened and closed by extending or closing two folding doors connected by hinges, so that they cannot be opened or closed reliably due to a reaction during opening and closing, or they can be opened or closed inadvertently. There is a drawback in that it opens and closes unexpectedly due to an unintentional external force other than the direction, and rattles.

  For this purpose, as shown in FIG. 24, a second arm 102 that can be projected and retracted is provided in the first arm 101, and engages with a locking portion 103 provided at the tip of the second arm 102 in the first arm 101. A plurality of locked portions 104a, 104b, and 104c are provided to constitute the stretchable tool 105, and one end of the stretchable tool 105 is used as the folding door body 2 on the bottom edge side of the folding door, and the other end is folded on the doorside side. It has been proposed to connect to (Patent Document 1). This folding door uses an extendable tool 105 that expands and contracts as it opens and closes, so that the locking portion 103 of the second arm 102 engages with the locked portion 104a of the first arm 101 when fully closed, The locking part 103 engages with the locked part 104c, and the locking part 103 engages with the locked part 104b in the middle of opening and closing, so that the folding door is opened and closed carelessly. This can be prevented.

  Next, in order to fold and open the door butt side folding door body and the door butt side folding door body, the folding door may kick out the connecting portion of the two folding door bodies in the folding direction at the initial stage of the opening operation. is necessary. Although this kicking-out operation can be performed manually, there are many cases in which a kicking device or a kicking-out mechanism is used for the folding door in order to be able to perform the opening operation with one behavior.

  As the kick-out mechanism, as shown in FIG. 25, the rotation center 107 of the hinge body 106 that connects the two folding door bodies 2 and 3 is set to the center L in the thickness direction of the two folding door bodies. A configuration in which the position is shifted in the folding direction is known (Patent Document 2). When the folding door using this kick-out mechanism is opened in parallel with the guide rail, the rotational center of the hinge body 106 is decentered and the above-mentioned positional deviation occurs, so that a component force in the folding direction is generated and the folding door body 2 and 3 are kicked out and folded.

  Moreover, as this kicking-out mechanism, as shown in FIG. 26, the small door body 5 is provided in the door tip side of the door tip side folding door body 3, and it has an inclined surface in the door tip side of the door tip side folding door body 3. A structure in which a kicking block 108 is protruded is known (Patent Document 3). In this folding door, the small door body 5 starts to move in parallel along the guide rail by the initial opening operation and comes into contact with the kicking block 108 of the door-end side folding door body, and further on the slope 109 of the kicking block 108. When riding up, a rotational force is generated by the cam action of the slope 109, and the door end side folding door body 3 is kicked out.

  However, in the folding door shown in FIG. 24, the extensible tool 105 as an auxiliary tool must be attached to the folding door body. In addition, since the attachment points are limited to the upper and lower edges straddling the folding doors 2 and 3, it is necessary to secure an attachment space and a rotation space for the telescopic tool 105 in this portion. In addition, the degree of prevention of inadvertent opening / closing and rattling of the folding door depends on the engagement strength between the locking portion 103 and the locked portions 104a, 104b, and 104c, but if this engagement strength is too strong, There remains a problem that requires a strong force to open and close the folding door.

  In addition, the folding door shown in FIG. 25 does not generate sufficient component force to smoothly fold unless the positional displacement dimension is increased, so that a large force is actually required for the initial opening operation.

  In addition, since the folding door shown in FIG. 26 moves the small door body separately from the two folding door bodies 2 and 3 during the initial opening operation, the small door body and the two folding door bodies 2 and 3 are different from each other. Since another guide rail must be juxtaposed in the horizontal direction, the structure becomes complicated, and in order to provide the kick block 108 on the door-end side of the door-end side folding door body, it is necessary to perform the initial opening operation. A relatively large force is required.

Therefore, a folding door and a revolving door which are simple in structure, light in opening and closing operation and free of rattling in a closed state and an open state, and their operation restricting device and kicking device are proposed. It is an object of the present invention to provide a steady rest device for use in the present invention .

The kick-out block 51 is attached with a mounting cover 55, and the mounting cover 55 is mounted on the wall surface 7 at a position where the kick-out arm 41 and the kick-out block 51 can be smoothly engaged and detached. The attachment frame 61 may be attached to the wall surface 7 in advance, and the attachment may be performed via the attachment frame 61.

  This folding door performs an opening operation by pulling the operation handle 5a of the small door body 5 toward the door bottom side, and performs a closing operation by pulling the operation handle 5a of the small door body 5 toward the door end side. . The movement of each part at each stage of the opening / closing operation is as follows.

(1) Initial Stage As shown in FIG. 8, the gear 17 meshes with the front end of the brake rack 23 when the folding door is in the fully closed state. Further, since the one end 21 of the stopper body is in contact with the front end wall 18 of the gear 17, the rotation of the gear 17 in the counterclockwise direction shown in the figure is restricted, and only the clockwise rotation is allowed (see FIG. 8 (a)).

  When the opening operation of the fully closed folding door 1 is started by pulling the operation handle 5a of the small door body 5 toward the door bottom, the folding door bodies 2 and 3 and the small door are opened at the initial stage of the opening operation. The body 5 moves horizontally along the guide rail 6 in the fully closed state without rotating along the guide rail 6 (FIGS. 7A and 7B). With this horizontal movement, the engaging head 46 engaged with the rectilinear groove 53 of the guide groove 52 of the kick-out block 51 moves to the inclined opening part 54 side. Further, with the horizontal movement of the folding door 1 in the fully closed state, the gear 17 whose front end wall 18 is in contact with one end of the stopper body 20 in the fully closed state of the folding door 1 rotates in the clockwise direction shown in the drawing. The front end wall 18 of the gear 17 moves away from the one end 21 of the stopper body 20 while retreating on the braking rack 23 toward the door bottom (FIGS. 8A and 8B).

(2) Kick-out stage The engaging head 46 engaged with the guide groove 52 of the kick-out block 51 in the initial stage of the opening operation moves to the opening side of the guide groove 52. 46 comes into contact with the inclined opening 54 and enters the kicking-out stage of the opening operation. In this kicking-out stage, the engaging head 46 slides on the inclined opening portion 54, and the folding door bodies 2 and 3 start to be folded by the component force generated thereby. It escapes from the inclination opening part 54, and a kicking-out step is completed (FIGS. 7B and 7C). Further, following the initial stage of the opening operation, the gear 17 engaged with the brake rack 23 continues to move backward on the brake rack 23 toward the door butt side while rotating, and when the kicking stage is finished, the gear 17 has its rear end wall. 19 contacts the other end 22 of the stopper body 20 (FIGS. 8B and 8C). In addition, the small door body 5 moves horizontally to the door bottom side after the initial stage without rotating, and then moves horizontally without rotating until the folding end stage.

(3) Intermediate stage When the opening operation is continued after the kicking-out stage, the two folding door bodies 2 and 3 are further folded, that is, the door-side folding door body 2 rotates in the clockwise direction shown in FIG. (D)). At this time, the gear 17 keeps rotating on the brake rack 23 until the door bottom side surface of the semicircular arc surface of the door bottom side folding door body 2 comes into contact with the contact body 27 while meshing with the brake rack 23. The rear end wall 19 of the gear also continues to press the other end 22 of the stopper body, and the intermediate stage of the folding is finished (FIG. 8D).

(4) Final stage After the intermediate stage of folding is completed after the door bottom side surface of the semicircular arc surface of the door bottom side folding door body 2 is in contact with the contact body 27, the folding operation is further continued. The door body 2 is further rotated in the clockwise direction in the drawing, and the two folding door bodies 2 and 3 are gradually folded toward the door bottom side (FIGS. 7D and 7E). At this time, the abutment body 27 relatively moves on the arcuate surface of the door butt side while contacting the door butt side as the door fold side folding door body 2 rotates. In addition, the door butt side folding door body 2 continues to rotate, and eventually one end 21 of the stopper body comes into contact with the front end wall 18 of the gear, and the two folding door bodies 2 and 3 are completely folded and the folding door 1 Is fully opened, and the folding end stage is finished (FIG. 7 (f), FIG. 8 (f)). In the fully opened state of the folding door 1, one end 21 of the stopper body is in contact with the front end wall 18 of the gear, so that the gear 17 is restricted from rotating in the counterclockwise direction shown in the figure, and only rotated in the clockwise direction. Allowed (FIG. 8 (f)).

  When closing the fully opened folding door 1, a closing operation is performed by pulling the operation handle 5a of the small door body 5 toward the door end side. The movement of each part in each stage of the closing operation is opposite to the movement of each part from the folding end stage to the initial stage.

  As described above, when the folding door 1 is in the fully closed state or the fully opened state, the one end 21 of the stopper body is in contact with the front end wall 18 of the gear, so that the gear 17 is rotated counterclockwise in the figure on the brake rack 23. Rotation is restricted, and only clockwise rotation is allowed. For this reason, the folding door 1 does not move further from the fully closed state toward the door end. Even if the folding door 1 is fully opened, the folding door bodies 2 and 3 do not move horizontally in the door-end direction while rotating in the door-end direction unless the folding door 1 is pulled in the door-end direction. In this way, the opening operation is started by pulling the operation handle 5a of the small door body from the fully closed state toward the door bottom, or conversely, the operation handle 5a of the small door body is pulled from the fully opened state toward the door tip direction. Only when the closing operation is started, the gear 17 can rotate on the braking rack 23 in the clockwise direction shown in the figure, so that the folding doors 2 and 3 in the fully closed state or the fully open state are inadvertently touched. Even if an unintended external force other than the opening / closing direction is applied, the opening / closing will not start or rattle.

[Other Embodiments]
In the operation restricting device 24 of the above-described embodiment, the fan-shaped gear 17 is used, the fan-shaped notch of the gear 17 is used as a rotation space, and the stopper body 20 is provided on the mounting base 11 (FIG. 2). As another embodiment of the operation restricting device 20, as shown in FIG. 9, a gear 17a having no notch is used as a gear, and a stopper pin 20a is provided as a stopper body on the side of the gear 17a. You may provide the rotation groove | channel 25 as a rotation space in the side. In this case, the stopper pin 20a moves in the rotation groove 25 toward the front end wall 18 or the rear end wall 19 with the rotation of the gear 17a and comes into contact therewith. Other parts and their operations are the same as in the above-described embodiment.

  Further, the stopper pin 20a may be one as shown in FIG. 9, or two stopper pins may be provided at a predetermined interval. Moreover, in the above-mentioned embodiment, although the attachment base 11 is attached to the upper end of the door butt side folding door body 2, the upper end itself of the door butt side folding door body 2 is good also as an attachment base.

  Although one kicking device is used in the above-described embodiment, two or more kicking devices may be used. FIG. 10 shows a case where two kicking devices, the first kicking device 40a and the second kicking device 40b, are used. The first kicking-out device 40a and the second kicking-out device 40b attach the mounting base 42 of each kicking arm portion 41 to the door butt side and the door tip side upper end of the door tip side folding door body 3 with a space therebetween. Yes. In addition, each kicking block part 51 is in a position where the kicking arm part 41 and each kicking block part 51 can be smoothly engaged and disengaged as in the above-described embodiment. Install it below.

  When these two kicking devices are used, the engaging head 46 engaged with the guide groove 52 of the kicking block portion 51 of each kicking device 40a, 40b in the above-described initial stage of the opening operation. Moves to the opening side of the guide groove 52, and eventually the engaging head 46 of the first kicking device 40a comes into contact with the inclined opening 54 first and enters the kicking stage of the opening operation. In the kicking stage by the first kicking device 40a, the engaging head 46 slides on the inclined opening portion 54, and the folding doors 2 and 3 start to fold due to the component force generated thereby. The engaging head 46 comes out of the inclined opening 54 and finishes the kicking-out stage (FIGS. 10A to 10C). Subsequently, the engaging head 46 of the second kicking device 40b comes into contact with the inclined opening portion 54 and enters the kicking stage of the opening operation. Similarly, the engaging head 46 slides on the inclined opening portion 54. Then, the folding doors 2 and 3 continue to be folded, and the engagement head 46 comes out of the inclined opening portion 54 and finishes the kicking-out stage (FIGS. 10C to 10E).

  In this kicking-out stage, the operation restricting device 24 continues to move backward on the braking rack 23 toward the door bottom side while the gear 17 meshed with the braking rack 23 rotates following the initial stage of the opening operation. When the step of kicking out the device 40b is completed, the rear end wall 19 of the gear 17 comes into contact with the other end 22 of the stopper body 20 (FIG. 8).

  Similarly, when three or more kick-out devices are used, the kick-out operation is started from the first kick-out device 40a provided on the outermost buttocks side of the door-end side folding door body 3 and provided on the outermost buttocks side. Finally, the final kicking device 40x finishes the kicking operation. Further, when the operation restricting device 24 finishes the kicking stage of the final kicking device 40x, the rear end wall 19 of the gear 17 comes into contact with the other end 22 of the stopper body 20.

  Thus, since two or more kicking devices can be used at the same time, the kicking amount of the folding doors 2 and 3 can be increased or decreased as necessary depending on the number of kicking devices to be used. . Moreover, even if it is a big folding door, the number of kick-out apparatuses can be increased and a folding door can be opened and closed with a light force.

  As shown in FIGS. 11 and 12, the kicking device may be provided with an opening 56 through which the engaging head 46 can pass in the anti-kicking direction in the rectilinear groove 53 of the kicking block 51. Even if it is not possible to perform the opening operation by turning the folding door body in the kicking direction due to circumstances such as the person falling down on the side of the folding door body kicking direction when this opening is provided, By passing the engagement head 46 from the opening 56, the folding door can be rotated in the anti-kicking direction to perform an opening operation.

  In this case, as shown in FIG. 6, if the decorative cover 57 covering the kick-out block 51 is made detachable with a bolt 58, the engaging head 46 can be anti-kicked simply by removing the decorative cover 57 from the wall surface 7. It can be rotated by passing it in the feeding direction. Further, it is desirable to provide a door stop 59 at the lower end of the decorative cover 57 in order to more reliably prevent the door tip side folding door body 3 from rotating in the anti-kicking direction.

In the embodiment shown in FIGS. 13, 14, and 15, a steady rest device 71 is provided below the door-end side folding door body. The steady rest device 71 includes a rotation shaft (hereinafter referred to as a second rotation shaft in order to distinguish the rotation shaft from the rotation shaft 13) 73 , a guide shaft 83, and a rotation bearing portion 75. It is composed. In the case shown in the figure, a pivot bearing 75 is provided at the lower end of the door bottom side of the door bottom side folding door body, the second rotation shaft 73 and the guide shaft 83 are attached to the base 72, and the base 72 is attached to the folding door. The second rotating shaft 73 and the guide shaft 83 are provided directly at the lower end of the door bottom side of the door bottom side folding door body 2 and the rotation bearing portion 75 is attached to the lower end of the wall surface. You may attach to the lower end of the door bottom side of the wall surface to attach.

  As shown in FIG. 13, the second rotation shaft 73 is formed in a columnar shape having a notch surface 74 on one side of the outer periphery. At this time, as shown in the drawing, only the upper part may be cut out, and the cutout step part 74a may be provided in the lower part. The guide shaft 83 is formed in a cylindrical shape having a smaller diameter than the second rotation shaft 73, and is attached to the base 72 at a predetermined interval from the second rotation shaft 73 to form a unit. In this embodiment, the shaft diameter of the guide shaft 83 is made smaller than the shaft diameter of the second rotation shaft 73 in order to make the terminal opening 82 of the rotation bearing portion 75 smaller. Thus, the same diameter as the shaft diameter of the second rotation shaft 73 or a larger diameter may be used.

  As shown in FIGS. 13 and 14, the rotational bearing portion 75 is provided with a linear guide portion 77 that guides the second rotational shaft 73 in a linear direction while sandwiching the second rotational shaft 73 between opposing walls, and the second rotational shaft 73 is provided at the starting end. A start end opening 76 is introduced. A restriction convex part 78 is provided below the outer wall of the starting end opening 76, and the second rotation shaft 73 of the second rotation shaft 73 is provided only when the notch surface 74 of the second rotation shaft 73 faces the restriction protrusion 78. The passage is allowed, and the passage of the second rotation shaft 73 is restricted as long as the notch surface 74 is not opposed to the restricting convex part 78. At the end of the linear guide portion 77, a rotation shaft locking recess 79 for locking the second rotation shaft 73 is provided.

  Further, the rotation bearing portion 75 is provided with a second linear guide portion 80 that is connected to the rotation shaft locking recess 79 and that guides the guide shaft 83 in a linear direction by holding the guide shaft 83 between parallel opposing walls. The end opening 82 through which the guide shaft 83 enters and exits opens to the inner wall side of the opposing wall, and is connected to the end of the second linear guide portion 80 so as to guide the guide shaft to the end opening 82. A portion 81 is provided.

  If the steady rest device 71 is used for the folding door, the folding door bodies 2 and 3 and the small door body 5 move horizontally in the door bottom direction by the above-described opening operation. The notch surface 74 is opposed to the restricting convex portion 78 provided in the starting end opening 76, passes through the restricting convex portion 78, and eventually engages with the rotating shaft locking concave portion 79 (FIG. 15A). (B)). At this time, the guide shaft 83 is guided by the second linear guide 80 and moves in the direction of the terminal opening 82. Thus, when the folding door bodies 2 and 3 and the small door body 5 move horizontally in the door bottom direction, the second rotation shaft 73 guided by the linear guide portion 77 and the guide shaft 83 guided by the second linear guide portion 80. Therefore, the rotation of the rotary bearing 75 can be restricted, and therefore the rotation of the folding door can be restricted.

  When the second rotation shaft 73 is engaged with the rotation shaft locking recess 79, the folding door bodies 2 and 3 are allowed to rotate but are restricted from moving in the horizontal direction. 3 (revolving doors) can be regulated separately from the horizontal movement and rotation, and the folding doors 2 and 3 can be prevented from shaking. In addition, when the folding door bodies 2 and 3 are rotated, the second rotation shaft 73 that is also engaged with the rotation bearing portion 75 attached to the folding door bodies 2 and 3 is rotated about the rotation center. For this reason, the cut-out surface 74 of the second rotation shaft 73 does not face the restricting convex portion 78 of the start end opening, and the relative movement of the second rotation shaft 73 in the direction of the start end opening 76 is restricted. The movement of the door can be restricted.

  When the folding doors 2 and 3 are rotated about the second rotation shaft 73 that is also engaged with the rotation bearing portion 75 as the center of rotation, the guide shaft 83 eventually leaves the terminal opening 82. (FIGS. 15B and 15C).

  The steady rest device 71 can be used as the movement restricting body. When the steady rest device 71 is used as the movement restricting body, the second rotation shaft moves the linear guide portion during horizontal movement in the opening direction until the folding door (rotary door) starts rotating. Only the horizontal movement is allowed linearly guided by 77, and when the second rotation shaft is locked in the locking recess 79, only the rotation of the rotary door is allowed.

  When kicking out the folding door in the anti-kicking direction, as shown in FIGS. 16 and 17, the door-side folding door body 2 can kick out in the anti-kicking direction around the guide shaft 83. .

  In the embodiment shown in FIGS. 18, 19, and 20, another steadying device 91 is provided below the door-end side folding door body. The steady rest device 91 includes a second turning shaft 93, a guide shaft 94, and a turning bearing portion 95. In the case of illustration, a rotary bearing 95 is provided on the floor surface of the opening provided with the folding door, the second rotary shaft 93 and the guide shaft 94 are attached to the base 92, and this base 92 is attached to the door-side folding door body. 2 is provided at the lower end of the door bottom, but may be attached in reverse.

  As shown in FIG. 19, the diameter of the second rotation shaft 93 is formed larger than the diameter of the guide shaft 94. A bush may be fitted around the outer periphery of each of these shafts 93 and 94.

  As shown in FIG. 20, when the door is fully closed, the rotation bearing portion 95 guides the second rotation shaft 93 on a straight line parallel to the door in the door butt direction with the second rotation shaft 93 interposed therebetween. A straight guide groove 97 is provided. Further, a fan-shaped recess 98 is provided so as to be connected to the door bottom side of the linear guide groove 97. The linear guide groove 97 and the fan-shaped recess 98 are arranged so that the inner side 97a of the opposing wall of the linear guide groove 97 and the side 98a formed by the straight line of the fan-shaped recess 98 are at right angles. Further, a locking recess 99 that restricts the movement of the second rotation shaft to the door bottom side is interposed between the outer other side 97b of the linear guide groove 97 and the other side 98b formed of a straight line of the fan-shaped recess. .

  If the steady rest device 91 is used for the folding door, the folding door bodies 2 and 3 and the small door body 5 move horizontally in the door bottom direction by the above-described opening operation, so the second rotating shaft 93 and the guide shaft 94 are It is guided by the straight guide groove 97 and moves horizontally in the door bottom direction. When the folding doors 2 and 3 start to rotate, the guide shaft 94 enters one side 98a of the fan-shaped recess from the inner side 97a of the linear guide groove (FIGS. 20A and 20B). When the folding door bodies 2 and 3 further turn, the second turning shaft 93 eventually engages with the locking recess 99 and is restricted from moving in the door bottom direction, and then the second turning shaft 93 is centered. Only rotation is allowed (FIGS. 20B and 20C). Thus, when the folding door bodies 2 and 3 and the small door body 5 move horizontally in the door bottom direction, the rotation of the folding door can be regulated by the second rotation shaft 93 and the guide shaft 94 guided by the linear guide groove portion 97. it can.

  The other steady rest device 91 can be used as the above movement restricting body in the same manner as the steady rest device 71 described above. When the steady rest device 91 is used as the movement restricting body, the second turning shaft 93 is moved straight in the opening direction until the turning of the folding door (rotating door) is started. When the second rotating shaft 93 is locked to the locking recess 99, only the rotation of the rotary door is allowed.

  Since the small door 5 is for facilitating the opening and closing operation, it is preferable to provide it, but it is not necessary. When the small door body 5 is not provided, the door handle side folding door body 3 may be provided with an operation handle (not shown).

  When the steady rest device 71 is used in a folding door with the small door body 5, as shown in FIG. 21, the concave portion 85 in which the guide shaft 83 of the steady rest device 71 can be engaged with the lower end on the door bottom side of the small door body 5. It is desirable to provide When the concave portion 85 is provided, when the folding door is fully opened, the small door body 5 can engage with the guide shaft 83 of the steady rest device 71 in the concave portion 83 to prevent the folding door from rattling. .

  The rail 6 for suspending the folding door may be one as shown in FIG. 1, but as shown in FIGS. 22 and 23, two rails 6 a and 6 b may be used. The number of rails may be increased. The two rails 6a and 6b are sliding rails using a base 87 that can move in the rail. The rail 6a suspends the small door body 5 and the rail 6a suspends the door-side folding door body 2. By appropriately increasing the rails in this way, the load applied to the rails can be distributed among the rails, and the degree of freedom in design can be increased.

  In the initial stage of the opening operation, the folding door and the revolving door move horizontally in the door bottom direction without rotating along the guide rail 6 in the fully closed state. The horizontal movement that does not rotate in the initial stage can be omitted by the setting of each device at the time of construction. That is, when the folding door is fully closed, the engaging head 46 is tilted by the kicking block so that the folding door body 2 can be kicked by the kicking device 40 simultaneously with the start of the opening operation. Each device may be adjusted so as to be positioned in the opening 54 so that the folding door can be kicked out (FIG. 7B).

  These folding doors can be used as bathrooms or elevator doors.
