Abstract

PROBLEM TO BE SOLVED: To improve the reliability of a panel shutter by arranging a roller for suspension on the outside of a chain arranged on the outside of a side end face of a panel and lowering and tilting a storage rail toward the direction of storage from the vicinity of a sprocket for driving panel. SOLUTION: A panel linkage chain 3 is mounted on both sides in an upper part of a panel 2 through a support shaft, and a roller for suspension 25 is attached on its outside. At the time of operation, when the panel 2 passes a sprocket for driving panel 8 in the direction of panel storage, the roller 25 is transferred on a storage rail 4. The roller 25 rolls on the rail 4 due to its inclination, and the panel 2 moves into a storage box 5 automatically in a condition in which the panels 2 are arranged in parallel and are suspended. When the roller 25 which is transferred on the rail 4 first reaches a descent terminal part of the rail 4, it comes into contact with a stopper 4a to prevent its coming off. Moreover, at this time, since the chain 3 is suspended in the inside of the rail 4, it is unnecessary to provide an exclusive space as is usual in the conventional method and make the storage box 5 compact.

Is provided with a stopper 4a (FIG. 1) for preventing the suspension roller 25 that has rolled on the storage rail 4 from falling off.

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 guiding the panel linking chain 3 in a proper meshing direction or a disengaging direction with the panel driving sprocket 8 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 is provided with 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 in which the storage rail 4 side of the panel driving sprocket 8 faces away from the tooth tip of the panel driving sprocket 8, 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 guide 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 near the upper end side of the guide rail 1 and on the side of the guide rail 1 includes an inner member 10 a located inside the tooth tip 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-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 deep space area in the storage box 5. Here, in the storage box 5, the lower end of the storage rail 4 is interrupted at a position near the depth end of the storage box 5 at a position corresponding to the installation space of the switchgear 13. The switchgear 13 is disposed by utilizing a deep space area in the storage box 5 that does not extend.

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.

Then, in the back space area in the storage box 5, the switchgear 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 mounted on the bracket 5a via a bearing 30. 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 rotation axis connecting the interlocking sprocket 14 and the first transmission sprocket 17 can adjust the distance between the interlocking sprocket 14 and the panel driving sprocket 8.

The panel driving sprocket 8 has a second transmission sprocket 18 coaxially, and an endless transmission chain 19 is meshed and wound around the second transmission sprocket 18 and the first transmission sprocket 17. The rotation output of the switch 13 is transmitted to the panel driving sprocket 8.

Here, the switchgear 13, the interlocking sprocket 14 and the first transmission sprocket 17 are substantially similar to the panel 2 at the storage position suspended by the storage rail 4 in the deep space area inside the storage box 5. They are arranged in parallel up and down directions.

With this arrangement, the storage box 5
Switch 13 and power transmission sprocket (interlocking sprocket 14 and first transmission sprocket 17) in the vehicle
Installation space can be minimized. Therefore, the installation space does not need to be particularly large, and the installation space of the storage box 5 is reduced as compared with the case where the switchgear 13 is externally attached to the storage box 5. Can be greatly reduced.

At a position above the storage rail 4 in the storage box 5, a chain tip guide rod 6 parallel to the storage rail 4 is disposed. 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.

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 to the chain tip guide rod 6. .

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, 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 linking chain 3 is not greatly loosened especially when the panel is stored, and the entanglement of the panel linking chain 3 during the panel lifting operation can be reliably prevented.

Further, since the free end portion 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 tip guide rod 6 disposed above the storage rail 4 is connected to the panel linking chain 3 which connects the panels 2 in a 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 manner, the upper end of the panel 2 that has moved up between the two guide rails 1 moves in an arc toward the storage rail 4 (panel storage direction side) along the tooth tip of the panel driving sprocket 8. 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.

When storing the panel, the roller chain 3
Move 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, as shown by the two-dot chain line (a) in FIG. Hangs regularly in a U-shape along the line.

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 roller chain 3 connecting the preceding panel 2 and the succeeding panel 2 hangs down, but this hanging down portion is guided downward along the side edge 9a of the panel storage side chain guiding member 9, so that The hanging portion of the roller 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. 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 above-mentioned 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 4 is driven via the roller chain 3 meshed with the panel drive sprocket 8. Upper panel 2
Are 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 comes into contact with the root of the panel linking chain 3 meshing with the panel driving sprocket 8 at the meshing position, the meshing releasing 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 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.

[0061]

As described above, according to the present invention, the suspension rollers are disposed further outside the panel connecting chain which is disposed outside the left and right end faces of each panel and connects the panels. As a result, the panel connecting chain can be hung inside the storage rail that rotatably supports the hanging roller in the panel side-by-side posture, and the storage chain is not hindered by the hanging of the panel connecting chain. The rails can be directly attached to the inside of the brackets on both sides of the storage box, so there is no need to specially secure a special space area for hanging the roller chain in the panel parallel posture area as in the past,
Accordingly, there is an effect that the storage box can be miniaturized and a compact receiving structure can be achieved.

In particular, according to the present invention, since the storage rail is gradually lowered from the vicinity of the panel driving sprocket toward the panel storage direction, the panel driving sprocket is moved toward the panel storage direction during the shutter opening operation. The hanging roller of the panel that has passed through can be automatically rolled and run sequentially toward the back of the panel storage direction by the inclination of the storage rail, so that the panel storage operation is always performed smoothly, There is an effect that the reliability of the shutter is improved.
