Field of the Invention The present invention relates to a panel shutter for vertically opening and closing a shutter opening / closing opening of a building by a plurality of panels. 2. Description of the Related Art A conventional panel shutter includes a pair of left and right guide rails arranged upright on both sides of a shutter opening and closing opening, and a storage box arranged above these guide rails. A plurality of upper and lower panels that move up and down between the guide rails are connected to each other by roller chains on both sides thereof, and the roller chains are meshed with panel driving sprockets in the storage box,
By the feed operation of the roller chain by the forward / reverse rotation drive of the panel driving sprocket, the panel is transferred to a vertical movement along a guide rail and a horizontal movement along a storage rail in the storage box. Has become. When the panel is moved laterally, hanging rollers rotatably supported on the left and right sides of the panel are rotatably supported on the storage rail so as to suspend and store the panel. [0003] In such a conventional panel shutter, the positional relationship between the roller chains provided on the left and right sides of the panel and the suspension rollers and the supporting structure are complicated, and the roller chain is not easily used. When the panel is transferred between the meshed panel driving sprocket and the storage rail, there is a problem that the transfer operation may not be performed smoothly. In addition, when the panel is moved along the storage rail, the roller chain hangs between the panels. In this case, the storage rail must be arranged so as not to hinder the roller chain. Special space must be secured to allow the space to hang down without any hindrance, and if such a space is secured, there is a problem in that the storage box becomes large and cannot be made compact. Was. A conventional shutter device of this type is disclosed in, for example, Japanese Patent Publication No. 2770312, and in this shutter device, a plurality of panels (also referred to as slats) are provided on both the left and right sides.

In the outer peripheral area, 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 area without a rail. Further, the lower end of the storage rail 4 that is inclined as described above is interrupted at a near position separated from the end of the depth 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 formed by the chain 3 by the forward and reverse rotation of the panel driving sprocket 8.
By the feeding operation, the sheet is successively transferred to a vertical movement along the guide rail 1 and a horizontal movement along the storage rail 4. When the panel 2 moves laterally toward the storage rail 4, the chain 3 between the horizontally adjacent panels 2 hangs down 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 chain 3 is abnormally bent (loose). Is provided with a chain looseness detecting device 7 for electrically detecting the chain slack. In the vicinity of the panel driving sprocket 8 in the storage box 5, a chain guiding member for guiding the chain 3 into contact with the panel driving sprocket 8 in a proper meshing direction or a disengaging direction during the movement of the panel 2. 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 extends from the tooth tip of the panel driving sprocket 8 to the sprocket.
Those are crowded around the sides of the bets 8, the upper edge 9b and the side edge 9

Further, the side edges 9a of the panel housing-side chain guide member 9 is a storage rail 4 side of the panel drive sprocket 8 in a state of being separated opposed to the addendum portions of 該Su sprocket 8
It extends downward from an outer portion 9d of the upper edge 9b . Obedience
Thus, the side edge 9a is formed on the sprocket 8 for driving the panel.
Cover the outside of the tooth tip with the panel storage direction side near the tooth tip
I have. The panel storage side chain guiding member 9
Are formed so as to be in contact with the chain 3 and to guide the chain 3 in the direction of meshing with the panel driving sprocket 8, the direction of unmating and the direction of the guide rail 1. On the other hand, the panel guide-side chain guide member 10 disposed on the guide rail 1 side near the upper end side of the guide rail 1 extends along the side surface of the panel driving sprocket 8.

Of the inner part 10a, 該Su this inward portion 10a continuously and along the sides of <br/> panel drive sprocket 8
Wherein the addendum circle of the sprocket 8 extends downwardly chain 3
And an outer portion 10b located in the vertical movement path of the panel, and comes into contact with the chain 3 which moves up and down along the guide rail 1 to guide the chain 3 in the direction of meshing with the panel driving sprocket 8 and in the direction of unmating. It is formed to be possible. 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 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 distance 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 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,
As shown in FIG. 1, the bearing body 30 is fitted and mounted so as to be position-adjustable in a notch 5b provided in the bracket 5a. Accordingly, the driving side rotating shaft 16 connecting the interlocking sprocket 14 and the first transmission sprocket 17
Can adjust the distance between the panel drive sprocket 8 and the panel drive sprocket 8. 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 fixed 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, as shown in FIG. 2, the projection 20 projects outside the left and right brackets 5 a via the bearing body 30, and the second transmission sprocket 18 is fixed to the outside projection end. 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, and the panel driving sprocket 8 is driven to rotate. It has become. 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 within the storage box 5. They are arranged in parallel up and down directions. With such an 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. A chain tip guide rod 6 parallel to the storage rail 4 is disposed 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. A free end portion (end side link portion) 3a of the chain 3, which is engaged with the panel driving sprocket 8 and extends in the panel storage direction, is movably moored to the chain tip guide rod 6. Thus, the free end 3a of the chain 3 moves along the chain leading guide bar 6 when the panel 2 moves up and down, so that the panel 2 first moves onto the storage rail 4 during the panel storing operation. The length from the pin 21 to the free end 3a of the chain 3 can be reduced. Accordingly, the free end side of the chain 3 is not greatly loosened particularly when the panel is stored, so that the chain 3 can be reliably prevented from being entangled during the panel elevating operation. Also, as described above, the free end 3 of the chain 3
Since a is always moored to the chain tip guide rod 6, the chain 3 does not come off from the panel driving sprocket 8 when the panel is extended, and the safety and reliability are greatly improved. Further, as described above, the chain tip guide bar 6 disposed above the storage rail 4 is a U-shaped chain that connects the panels 2 suspended in parallel to each other and suspended from the storage rail 4. Because it does not interfere with the bending and drooping,
It is not necessary to provide a special space for disposing the chain tip guide rod 6 in the storage box 5, so that 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 through the chain 3 meshed with the panel. Panel 2
When the upper end of the panel 2 reaches the panel driving sprocket 8, the upper end of the panel 2 moves circularly with the chain 3 along the pitch circumference of the panel driving sprocket 8 and the storage rail 4.
Is guided in the direction of. 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 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 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,

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, disengagement with is carried out very reliably and efficiently, the chain 3 and the panel housing-side chain guide member Since the excessive force generated at the time of disengagement does not concentrate on one place, unnecessary damage hardly occurs in 9 and the life thereof 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 portion 9c comes into contact with the root of the meshing position of the chain 3 meshing with the panel driving sprocket 8, the meshing is released, so that the mesh releasing effect is extremely remarkable. Further, the inner part 9c and the outer part 9d
Are located above a horizontal line passing through the axis of the panel driving sprocket 8, so that the disengagement of the chain 3 from the panel driving sprocket 8 can be performed very efficiently and effectively. Moreover, the inner part 9c and the outer part 9
Since d is located near the starting end of the storage rail 4 when viewed from the side as shown in FIG. 1, the engagement of the chain 3 can be released at an extremely effective timing. 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. As described above, when each panel 2 changes its direction from the upward vertical movement along the guide rail 1 to the horizontal movement along the storage rail 4, at the initial stage of the horizontal movement, the preceding panel 2 and the succeeding panel 2 The chain 3 connecting the chain 3 hangs down, but the chain hang down portion is guided downward along the side edge 9a of the panel storage side chain guide member 9, so that the hang down portion of the chain 3 is used for panel driving. Entanglement with the sprocket 8 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 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. 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 chain 3 is reliably guided to 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. Is done. Further, the 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, disengagement with is carried out very reliably and efficiently, the chain 3 and the panel housing-side chain guide member 10 Since the excessive force generated at the time of disengagement does not concentrate on one place,
Unnecessary damage is unlikely to occur, and its life is extremely long. In particular ,
Such an effect is extremely important because the contact between the two always occurs at the time of the reverse starting. Since the inner portion 10a comes into contact with the root of the meshing position of the chain 3 meshing with the panel driving sprocket 8, the meshing is released, so that the meshing releasing effect is extremely remarkable. If the panels 2 are folded or clogged in the guide rail 1 in the above-described lifting and lowering operation of the panel 2, the panel 2 becomes a scandal in which the panel 2 cannot be moved. It is a factor of occurrence. However, in this case, since abnormal refraction occurs in the chain 3, the abnormal refraction is detected by the chain looseness detecting device 7. Respond immediately to scandals. As described above, according to the present invention, the left and right
