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.

In such a panel shutter, the side near the upper end of the guide rail 1 extending into the storage box 5 is located near the lower part of the panel driving sprocket 8 and the abnormal refraction of the panel linking chain 3 ( A chain slack sensing device 7 for electrically sensing (slack) is provided.

In the vicinity of the panel driving sprocket 8 in the storage box 5, a chain for contacting and guiding the panel linking chain 3 to the panel driving sprocket 8 in an appropriate meshing direction or a disengaging direction during the movement of the panel 2. Guide members 9 and 10 are arranged.

In these chain guide members 9 and 10, the storage rail 4 is located near the panel driving sprocket 8.
The panel storage side chain guide member 9 disposed on the side protrudes from the inside of the bracket 5a of the storage box 5 and wraps around the side of the panel driving sprocket 8 to form an upper edge 9b.
And a side edge 9a.

More specifically, the upper edge 9b of the panel storage-side chain guide member 9 includes an inner member 9c located inside the addendum circle of the panel driving sprocket 8, and an outer end of the addendum circle and the storage box. And an outer member 9d located in the movement path of the panel linking chain 3 that enters and exits the inside of the panel connecting chain 3.

Further, the side edge 9a of the panel storage side chain guide member 9 extends downward in a state where the side edge 9a of the panel drive sprocket 8 is spaced apart from and faces the tooth tip of the panel drive sprocket 8 on the storage rail 4 side. The hanging portion of the panel linking chain 3 is prevented from being entangled with and engaged with the panel driving sprocket 8.

The panel storage side chain guide member 9
Are formed so as to be in contact with the panel connecting chain 3 so that the panel connecting chain 3 can be brought into contact with the panel driving sprocket 8 in the meshing direction, the mesh releasing direction, and the guide rail 1 direction.

On the other hand, the panel entrance / exit side chain guide member 10 disposed on the guide rail 1 side near the upper end side of the guide rail 1 includes an inner member 10a located inside the addendum circle of the panel driving sprocket 8. An outer member 10b located outside the addendum circle and in the movement path of the panel linking chain 3, and contacts the panel linking chain 3 to disengage the panel linking chain 3 in the meshing direction and the meshing direction. It is formed so as to be able to contact and guide in the direction and the guide rail 1 direction.

In the above, at least one of the panel storage side chain guide member 9 and the panel entrance / exit side chain guide member 10 constitutes a chain / sprocket guide 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 sides of the mounting base 13a.

In the back space area inside the storage box 5, the switch 13 is attached to the bracket 5a on one side thereof.
At the time of the mounting, a bolt 28 is inserted into the long hole 13b of the mounting base 13a of the switchgear 13, and a nut 29 is screwed into the bolt 28 to tighten the mounting base 13a to the bracket 5a. It is fixed. 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. 1, and an interlocking sprocket 14 is linked to 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 rotating 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 that is supported at a 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.

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.

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, by forming the side piece of the bracket 5a as the bracket mounting support portion 5c, the driven-side rotary shaft 20 supporting the panel weight serving as a dynamic load when the panel is raised and lowered.
Can be arranged at a position closest to the bracket mounting support portion 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.

A chain tip guide bar 6 parallel to the storage rail 4 is arranged at a position above the storage rail 4 in the storage box 5. The chain tip guide rod 6 is disposed by effectively utilizing an upper space between both end surfaces of the panel 2 suspended by the storage rail 4 and the bracket 5a.

The 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 anchored to the chain tip guide rod 6. .

As a result, the free end 3a of the panel linking chain 3 moves along the chain tip guide bar 6 when the panel 2 is moved up and down, so that the free end 3a 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.

Accordingly, the free end side of the panel connecting chain 3 does not loosen greatly when the panel is stored, and the entanglement of the panel connecting chain 3 during the panel elevating operation can be reliably prevented.

As described above, since the free end 3a of the panel linking chain 3 is always moored to the chain tip guide rod 6, 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 tip guide rod 6 disposed above the storage rail 4 is connected to the panel connecting chain 3 which connects the panels 2 in the parallel posture suspended by the storage rail 4 to the 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.

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 which 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 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.

In the above, the panel 2 is the guide rail 1
When the panel drive sprocket 8 is connected to the panel connecting chain 3 first when the panel is spliced from the vertical movement in the serial posture along the storage rail 4 to the horizontal movement in the parallel posture along the storage rail 4, the meshing is performed. Since the panel entrance / exit chain guide member 10 extending in the direction guide is disposed, the inner member located inside the tooth tip circle of the panel driving sprocket 8 which the panel entrance / exit chain guide member 10 has. The panel linking chain 3 is reliably guided in a predetermined direction with respect to the panel driving sprocket 8 by the outer member 10b located outside the addendum circle and in the movement path of the panel linking chain 3.

Even if the panel linking chain 3 and the panel driving sprocket 8 are abnormally engaged due to some unexpected action, the panel receiving side chain guiding member is not provided. 9
, The panel driving sprocket 8 that the panel storage side chain guide member 9 has
An inner member 9c located inside the addendum circle and above a horizontal line passing through the axis of the panel drive sprocket 8, and a panel which enters and exits the storage box 5 outside the addendum circle of the panel drive sprocket 8. An outer member 9d located in the movement path of the connecting chain 3 and above a horizontal line passing through the axis of the panel driving sprocket 8 so that the panel connecting chain 3 can be properly engaged with the panel driving sprocket 8; Since the contact link is guided in the direction of disengagement and the direction of the guide rail 1, the panel linking chain 3 is securely separated from the panel driving sprocket 8, and the above-described storing operation of the panel 2 is smoothly performed.

Here, the inner member 9c and the outer member 9d
The functions and effects of are described in more detail. Since the panel linking chain 3 comes into contact with two portions of the inner member 9c located inside the addendum circle of the panel driving sprocket 8 and the outer member 9d located outside the addendum circle. This contact area is extremely enlarged, and the disengagement is performed very reliably and efficiently, and the unreasonable force generated at the time of disengagement is concentrated on the panel connecting chain 3 and the panel storage side chain guiding member 10 at one place. Because there is no unnecessary damage, it is unlikely to cause unnecessary damage and its 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.

Further, since the inner member 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 release the meshing, the meshing releasing effect is extremely remarkable. is there.

Further, the inner member 9c and the outer member 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. In addition, since the inner member 9c and the outer member 9d are located near the starting 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.

At the time of storing the panel, 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 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 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 chain guide member 9, so that the panel connecting chain 3 It is possible to reliably prevent the hanging portion of the linking chain 3 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. 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 rotationally driven in the counterclockwise direction in FIG. 1 by the rotation output, so that the storage rail is moved 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.

At this time, in the vicinity of the panel driving sprocket 8, first, the side link 9a and the upper edge 9b of the panel storage side chain guiding member 9 make sure that the panel linking chain 3 is at a predetermined meshing position of the panel driving sprocket 8. 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.

That is, the panel linking chain 3 is connected to the inner member 1 located inside the tip circle of the panel driving sprocket 8.
0a and the outer member 10b located outside the addendum circle, so that the contact area is greatly enlarged, and the disengagement is performed very reliably and efficiently. Since unreasonable force generated at the time of disengagement does not concentrate on one place in the linking chain 3 and the panel entrance / exit-side chain guide member 10, useless damage hardly occurs and the life is extremely long. In particular, since the contact between the two always occurs at the time of the reverse starting, such an effect is extremely important.

Further, since the inner member 10a releases the meshing by coming into contact with the root portion of the meshing position of the panel connecting chain 3 meshing with the panel driving sprocket 8, the meshing releasing effect is extremely remarkable. is there.

If the panels 2 are folded or clogged in the guide rail 1 in the above-described process of raising and lowering the panels 2, the panels 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 with each other.

[0069]

As described above, according to the present invention, the storage rail which is arranged in the storage box and rotatably supports the hanging roller of the panel which has passed the panel driving sprocket in the panel storage direction. Since a stopper is provided for stopping the suspension roller at a predetermined position opposite to the panel driving sprocket, the suspension roller may fall off the storage rail when the panel is stored by the stopper. And prevents the panel moving along the storage rail in the panel storage direction from colliding with a back wall in the storage box or a switchgear arranged in the back of the storage box. effective.

Further, a space for mounting the switch can be secured between the inner wall of the storage box and the stopper.
A switchgear can be attached by effectively using the back area in the storage box, and therefore, the installation area of the storage box is reduced as compared with the conventional case where the switchgear is externally attached to the storage box, There is an effect that versatility in the installation construction can be obtained.
