And an outer portion 10b which is located in the vertical movement path, in contact with Ruchi En 3 to lift along the guide rails 1 wherein the
It is contacted inducible form the meshing direction and disengagement direction Ji En 3 to a panel drive sprocket 8. In the above, at least one of the panel guiding side chain guiding member 9 and the panel entrance / exit side chain guiding member 10 constitutes a chain / sprocket guiding device. In the vicinity of the panel entrance of the storage box 5,
A panel guide 11 is provided for smoothly guiding a panel roller 22 below each panel 2 in a panel storage direction and a panel extension direction. A switchgear 13 is arranged in a depth space in the storage box 5. Here, storage box 5
, The lower end of the storage rail 4 is interrupted at a position away from the depth end of the storage box 5 by a distance corresponding to the installation space of the switchgear 13, so that the storage box in which the storage rail 4 does not extend The switchgear 13 is arranged by utilizing the depth space area in 5. As shown in FIG. 1, the switchgear 13 has an integral mounting base 13a, and has vertically long mounting holes 13b at both upper and lower portions of the mounting base 13a. In the back space area in the storage box 5, the switch 13 is attached to the bracket 5a on one side thereof.
At the time of the attachment, a bolt 28 is inserted through the long hole 13b of the attachment base 13a of the switchgear 13,
The mounting base 13a is fixed to the bracket 5a by screwing and tightening a nut 29 to the bolt 28. Therefore, if the nut 29 is loosened, the mounting position of the switch 13 can be adjusted in the vertical direction by an amount corresponding to the length of the long hole 13b. The switchgear 13 has an output sprocket 130 as shown in FIG. 1, and an interlocking sprocket 14 is interlocked with the output sprocket 130 via an interlocking chain 15. The interlocking sprocket 14 has a first transmission sprocket 17 coaxially, and is rotatably attached to the bracket 5a via a bearing 30. Here, the bearing body 30 is, as shown in FIG.
Is fitted and mounted so as to be position-adjustable with respect to the notch 5b provided at the bottom. Therefore, the space between the driving side rotating shaft 16 connecting the interlocking sprocket 14 and the first transmission sprocket 17 with the panel driving sprocket 8 can be adjusted. Both ends of the driving-side rotary shaft 16 project outside the left and right brackets 5a via bearings 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 supported at the position above the guide rail 1 in the left and right brackets 5a.
As shown in FIG. 2, as shown in FIG. 2, the projection 20 projects outside the left and right brackets 5 a via the bearing 30, and the second transmission sprocket 18 is fitted to the outside projection end. Then, the first transmission sprocket 17 and the second transmission sprocket 17
An endless transmission chain 19 is meshed and wound around the transmission sprocket 18, whereby the rotation output of the switch 13 is transmitted to the left and right panel driving sprockets 8, so that the panel driving sprocket 8 is rotated. It has become. Accordingly, the panel driving sprocket 8 and the interlocking sprocket 14 are disposed inside the bracket 5a, and the first transmission sprocket 17, the second transmission sprocket 18 and the transmission chain 19 are disposed outside the bracket 5a. In the above, 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 for supporting the panel weight, which is a static load in the panel storage state, can be arranged at a position farther from the bracket mounting support portion 5c than the driven side rotation shaft 20. Such an arrangement is advantageous in the strength performance of the entire storage box 5 including the bracket 5a. In the storage box 5, the guide rail 1 is a panel elevating unit, the storage rail 4 is a panel storage unit, and the 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 area of the main body), 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, the driving side rotating shaft 16 and the interlocking sprocket 14 Are arranged in the up-down direction substantially parallel to the panel 2 in the storage position suspended by. 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 space required for installation of 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. A chain guide bar 6 extending in a direction along the storage rail 4 is arranged at a position above the storage rail 4 in the storage box 5. The chain guide bar 6 is disposed above the space between the both end surfaces of the panel 2 suspended on the storage rail 4 and the bracket 5a, and effectively uses the space. The chain guide rod 6 has a free end portion (end side link portion) of the panel connecting chain 3 which meshes with the panel driving sprocket 8 and extends in the panel storage direction.
3a is movably moored. Thus, when the panel 2 is moved up and down, the free end 3a of the panel linking chain 3 is
, The length from the pin 21 of the panel 2 that first moves onto the storage rail 4 during the panel storage operation to the free end 3a of the panel linking chain 3 can be reduced. Accordingly, the free end side of the panel connecting chain 3 is not greatly loosened particularly when the panel is stored, and the entanglement of the panel connecting chain 3 during the panel elevating operation can be reliably prevented. Further, since the free end portion 3a of the panel connecting chain 3 is always moored to the chain guide bar 6 as described above, the panel connecting chain 3 is detached from the panel driving sprocket 8 when the panel is extended. Without greatly improving safety and reliability. Further, as described above, the chain guide bar 6 arranged above the storage rail 4 is a U-shaped panel connecting chain 3 that connects the panels 2 in a parallel posture suspended on the storage rail 4. Since it does not become an obstacle when bending and hanging down, it is not necessary to provide a special space for disposing the chain guide bar 6 in the storage box 5, so that a compact housing structure can be achieved. Next, the operation will be described. When the switch 13 is activated in the shutter opening direction, the rotational driving force is
Interlocking sprocket 14 from output sprocket 130 via interlocking chain 15 → first transmission sprocket 17 →
The power is transmitted from the transmission chain 19 to the second transmission sprocket 18 to the panel driving sprocket 8, whereby the panel driving sprocket 8 is rotated clockwise in FIG. Thus, the panel driving sprocket 8
The panel 2 between the guide rails 1 is pulled up via the panel linking 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 tooth 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 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 moved to the lower end of the storage rail 4. Abuts against the stopper 4a provided in the storage rail 4 to prevent the storage rail 4 from falling off. 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. During the above-described panel storage operation ,
On the guide rail 1 side of the panel driving sprocket 8,
Inner part 10a of panel entrance side chain guide member 10
And by an outer part 10b, before the winding En 3 or reliably in a predetermined engagement direction with respect to the panel drive sprocket 8

Also on the rail 4 side, the chain guide member on the panel storage side
The panel drive is performed by the inner part 9c and the outer part 9d of the

break away. Therefore, the storage operation of the panel 2 as described above is
Always performed smoothly . Here, the inner part 9c and the outer part 9d
The functions and effects of are described in more detail . The chain 3
Along the side of the panel driving sprocket 8
A laterally inner portion 9c located within the diameter of the addendum circle of the rocket 8 and a panel driving sprocket continuously connected to the inner portion 9c.
Lateral direction from the tip of the rocket 8 to the panel storage direction
Since the coming into contact with the two successive portions of an outer portion 9d extending, the contact area is extremely enlarged, the disengagement is carried out very reliably and efficiently, Ji En <br/> 3 and panel Unnecessary force generated at the time of disengagement is not concentrated on one location in the storage-side chain guide member 9 , so that unnecessary damage is unlikely to occur and the life is extremely long. In particular, since such contact always occurs at the time of the above-mentioned reverse starting, such an effect is extremely important. Since the inner portion 9c comes into contact with the root of the panel connecting chain 3 meshing with the panel driving sprocket 8 at the meshing position to cancel the meshing, the meshing canceling effect is extremely remarkable. is there. Further, an inner part 9c and an outer part 9d
Are positioned above a horizontal line passing through the axis of the panel driving sprocket 8, so that the disengagement of the panel linking chain 3 from the panel driving sprocket 8 can be performed very efficiently and effectively. Moreover, since the inner portion 9c and the outer portion 9d are located near the start end of the storage rail 4 as viewed from the side as shown in FIG. 1, the engagement of the panel linking chain 3 is released at an extremely effective timing. be able to. When the panel is stored, the roller panel linking chain 3 moves into the storage box 5 together with the first panel 2 without being entangled by the chain guide rod 6, and in the folded storage state of the panel 2, two points are shown in FIG. As shown by the dashed line (a), the panel 2 is in a state of regularly hanging down in a U-shape along the side surface of each panel 2. As described above, when each panel 2 changes its direction from the vertical movement upward along the guide rail 1 to the horizontal movement along the storage rail 4, the leading panel 2 and the succeeding panel 2 are initially in the horizontal movement. The chain linking the panel connecting chain 3 hangs down, but the chain hanging down portion is guided downward along the side edge 9a of the panel storage side chain guide member 9, so that the hanging portion of the panel linking chain 3 is driven by the panel drive. Entanglement with the sprocket 8 for use can be reliably prevented, so that damage to the storage rail 4 and elevation of the panel 2 are not hindered. 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 in the counterclockwise direction in FIG. 1 by the rotation output, and is stored via the roller panel linking chain 3 meshed with the panel drive sprocket 8. The panel 2 on the rail 4 is sequentially pulled out in the feeding direction. At this time, in the vicinity of the panel driving sprocket 8, first, the panel linking chain 3 is securely positioned at the predetermined meshing position of the panel driving sprocket 8 by the side edge 9 a and the upper edge 9 b of the panel storage side chain guide member 9. Will be guided to. Further, the panel linking chain 3 is smoothly separated from the panel driving sprocket 8 by the other panel entrance / exit side chain guide member 10. Here, the drive of the panel driving sprocket 8 is described.
At the entrance / exit side (guide rail 1 side),
Is along the side of the panel driving sprocket 8
The inside of the vertical direction located within the diameter of the tip circle of the sprocket 8
Panel 10a and a panel connected to the inner region 10a.
The longitudinal direction extending downward from the tooth tip of the driving sprocket 8
Since decided to contact two consecutive portions of the outer portion 10b, the contact area is extremely enlarged, with the disengagement is carried out very reliably and efficiently, Ji En 3 and the panel entrance-side chain guide member Since excessive force generated at the time of disengagement does not concentrate on one place, unnecessary damage hardly occurs on 10 and the life thereof is extremely long. In particular <br/>, contact therebetween, so that it always occurs at the inverse activation, such effect is very important. Since the inner portion 10a comes into contact with the root of the panel connecting chain 3 meshed with the panel driving sprocket 8 at the meshing position to cancel the meshing, the meshing canceling effect is extremely remarkable. is there. 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 will not move, causing a scandal. Is a factor. However, in this case, the panel connecting chain 3
In this case, abnormal refraction occurs, and by detecting the extraordinary refraction by the chain looseness detecting device 7, it is possible to immediately cope with a scandal situation such as the occurrence of a major accident caused by folding or clogging of the panels 2 mutually.
