Field of the Invention The present invention relates to a panel shutter for raising and lowering an opening of a building with a shutter curtain formed by connecting a plurality of panels in series by a roller chain. It is about. 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 in series by roller chains on both left and right sides, and the roller chains are meshed with panel driving sprockets in the storage box. By the feed operation of the roller chain by forward and reverse rotation drive of, the panel, the vertical movement in a series posture along the guide rail,
It is adapted to be transferred to a horizontal movement along a storage rail in the storage box. In the panel side-by-side orientation, the hanging rollers rotatably supported on the left and right sides of each panel are rotatably supported on the storage rails, and the panels are suspended and stored. [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 panels are stored in a parallel posture along the storage rails, the roller chains hang down between the panels.In this case, the storage rails must be arranged so as not to obstruct the roller chains. Must secure a special space area for hanging the roller chain without any trouble.
If such a space area is particularly secured, there is a problem that the storage box becomes large and a compact receiving structure cannot be obtained. 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. The lower end of the eye panel member is connected to the end face with a pin, and a hanging roller is rotatably supported at the upper end of the eye panel member, and a roller chain is connected to the roller shaft, whereby the panel mutual connection is achieved. Are connected in series on both the left and right sides,
There is a problem that the connection between the panels becomes very complicated. Further, as described above, the hanging roller pivotally supported on the upper end portion of the eye panel member is coaxially connected to the hanging roller, and is provided inside the roller chain meshed with the panel driving sprocket (both the end faces on both sides of the panel and the roller). Between the brackets on both sides of the storage box and the storage rails so that they do not interfere with the roller chain that hangs when the panel is stored. In particular, a special space area for hanging the roller chain must be ensured, which complicates the structure and increases the size of the storage box, making it impossible to provide a compact storage structure. Was. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a component arrangement which does not require a special space area for hanging a roller chain in a panel parallel posture. It is another object of the present invention to provide a panel shutter capable of always and smoothly moving a panel in a storage box without causing the panel to sway. [0007] A panel shutter according to the present invention is disposed on both sides of a shutter opening / closing opening.

In the panel shutter for transferring to the lateral movement along the storage rail, the panel connecting chain is provided outside the left and right end surfaces of the panel , and the hanging roller is provided further outside the panel connecting chain. And the storage rails are different from the guide rails.
Cut the panel from the vicinity of the panel drive sprocket.
The panel is laid horizontally toward the storage direction, and
Is provided with a projection for the lower guide, inside the panel storage section
The one in which the upper end of the panel is provided with a panel guide for guiding the lower guide protrusion of the panel in a predetermined panel moving direction at the point when it reaches the vicinity of the panel drive sprocket. An embodiment of the present invention will be described below. FIG. 1 is a longitudinal sectional view showing a storage box portion of a panel shutter according to an embodiment of the present invention, and FIG. 2 is a schematic perspective view of a panel drive system of FIG. In the drawing, reference numeral 1 denotes a pair of left and right guide rails, and these guide rails 1 are composed of vertical guide rails arranged upright on both sides of a so-called shutter opening / closing opening such as a doorway of a building or a window. Reference numeral 2 denotes a plurality of upper and lower panels for raising and lowering the space between the two guide rails 1. These panels 2 are shown in FIG.
And a rectangular frame 2a as shown in FIGS.
A suitable panel face plate 2b is attached to the panel. As shown in FIGS. 3 and 4, pins (support shafts) 21 projecting outward from both side end surfaces of the panel 2 are provided on both upper sides of the panel 2.
Is rotatably inserted and connected to the panel connecting chain 3 composed of a roller chain via a sleeve-shaped attachment 24 so as to be rotatable and movable in the thrust direction. More specifically, as shown in FIGS. 3 and 4, pin brackets 26 are provided on both side end surfaces of the upper portion of the panel 2, and the pins 21 are inserted into the pin brackets 26 so as to be movable in the thrust direction. The pin 21 is fixed by a screw 27 at a movement adjustment position in the thrust direction. In this manner, the plurality of panels 2 that move up and down between the two guide rails 1 are opened and closed by the respective pins 21.
Through the panel connecting chain 3 outside the both side end faces of each panel 2. On the pins 21 of each panel 2, a hanging roller 25 located further outside the panel linking chain 3 is rotatably mounted. Further, a lower guide roller (a lower guide projection) 22 is rotatably supported on both lower sides of each panel 2. The lower guide roller 22 has a different moving path from the pins 21. For this reason, when the panels 2 are connected in series by the panel connecting chain 3 so that the panels 2 have the same vertical plane between the guide rails 1, the lower guide rollers 22 hinder the panel connecting chain 3. There is no such thing. Therefore, the panels 2 can be easily connected to each other by the panel connecting chain 3 so as to be in the same vertical shape, and the lower guide roller 22 does not interfere with the panel connecting chain 3 even when the shutter is opened and closed. The opening and closing operation can be performed smoothly and reliably at all times. A storage box (panel storage section) 5 is disposed above the guide rail 1.
Comprising a vertical bracket 5a in the left and right sides, these blanking

A pair of left and right panel driving sprockets 8 located above both guide rails 1 are pivotally supported inside the bracket 5a, and the chain 3 is meshed with these panel driving sprockets 8. . A storage rail 4 is disposed inside the bracket 5a. The storage rail 4 is located above a horizontal line passing through the axis of the panel driving sprocket 8 between the bracket 5a and the panel driving sprocket 8. In the example shown in the drawing, the panel storage direction side gradually descends gradually and inclines to the panel storage direction side, and the hanging roller of the panel 2 that has passed the panel driving sprocket 8 in the panel storage direction side. 25 is rotatably supported. Therefore, the front end side of the storage rail 4 intervenes between the bracket 5a and the panel driving sprocket 8, and overlaps with a cylindrical area having a cross section of the rotation circular locus of the panel driving sprocket 8. ing. The storage rail 4 has a mounting surface for the bracket 5a and a rolling surface of the suspension roller 25, and a space is formed below the rolling surface.
The rotation axis 20 of the panel driving sprocket 8 is spaced apart from the axis of rotation of the panel driving sprocket 8 corresponding to the movement locus of the suspension roller 25 according to the chain feed direction of the panel driving sprocket 8. 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 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 connecting 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 a proper 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 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
a. More specifically, the upper edge 9b of the panel storage-side chain guide member 9 extends along the side surface of the panel driving sprocket 8 within the radius of the tip circle of the sprocket 8.
An inner portion 9c which forms a lateral moving path of the chain 3 is located, and continuous with the inner portion 9c the sprocket
And an outer portion 9d extending outwardly from the addendum circle of the sprocket 8 in a direction along the side surface of the chain 8 and located in the lateral movement path of the chain 3. 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.

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 to guide the lower guide roller 22 below each panel 2 smoothly in the panel storage direction and the panel feeding direction. A switchgear 13 is disposed 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. 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, 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 the bearing body 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 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 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 description, 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 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 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 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 particularly when the panel is stored, and it is possible to reliably prevent the panel linking chain 3 from being entangled during the panel elevating operation. Further, since the free end portion 3a of the panel connecting chain 3 is always moored to the chain leading guide bar 6 as described above, the panel connecting 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 on the storage rail 4 and has a U-shape. Since it does not become an obstacle when it bends and hangs down in a character shape, it is not necessary to provide an extra space for arranging the chain tip 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 lower guide roller 2 of 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 lower guide roller 2
When the panel 2 is guided obliquely upward by the panel guide 11, the panel 2 moves while maintaining the vertical posture in the anti-lateral shake state when passing the panel driving sprocket 8 toward the panel storage direction. 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 Then, 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

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 member 9c comes into contact with the root of the meshing position of the panel linking chain 3 meshing with the panel driving sprocket 8, the meshing release 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 the panel is stored, 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. In this way, 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. Here, the drive of the panel driving sprocket 8 is described.
At the entrance / exit side (guide rail 1 side),

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. Further, since the inner member 10a comes into contact with the root of the panel connecting chain 3 meshing with the panel drive 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 will not move, causing a scandal. Is a factor. However, in this case, the panel linking 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.
