Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a panel shank reversal drive device that opens and closes shutter openings such as entrances and exits of buildings and roofs of arcades and the like using a plurality of interconnected panels.

[Conventional technology]

A conventional panel shutter device has a pair of left and right vertical guide rails that are placed upright on both sides of the shutter opening/closing opening, and a panel storage box (hereinafter referred to as storage box) that is placed on the upper end of these vertical guide rails. , a plurality of panels bendably connected by a pair of left and right chains movable into the box along the vertical guide rails and mounted between the vertical guide rails, and a sprocket in which the chains are engaged. and panel driving means for driving the panel up and down via the chain by rotationally driving the sprocket, and the panel is arranged adjacent to each other in the same vertical plane between the vertical guide rails. It is designed to be pulled out in the unfolded and closed state, and suspended in the parallel folded state within the box.

[Problems to be Solved by the Invention] The conventional panel shutter device is configured as described above, and since the panel can only be moved in a vertical position and cannot be moved horizontally, the appearance of the shutter is In addition, the location where the shutter can be installed is also limited, and therefore it cannot be applied to arcades, sunrooms, greenhouses, etc., and has poor versatility.Moreover, it requires a storage box, and it is difficult to install the shutter inside the storage box. In order to allow the panels to be moved horizontally in the storage direction when the panels are stored, a gap must be provided between the panels suspended between the vertical guide rails, and this gap between the storage box and the panels is required. This poses problems such as increasing the size of the entire device. This invention was made to solve the above-mentioned problems, and allows the shutter opening/closing opening between the vertical guide rails and the roof of an arcade etc. to be smoothly opened and closed in series without requiring a storage box. It is an object of the present invention to provide a panel shutter reversing drive device capable of smoothly moving each panel by changing the direction of each panel so that the inner panel surface facing the indoor side of the vertical guide rail becomes the lower surface of the roof.

[Means to solve the problem]

The panel shutter reversing drive device according to claim 1 of the present invention extends outdoors via a panel reversing box to the upper ends of a pair of left and right guide rails that are arranged upright on both sides of a shutter opening/closing opening, and drives each panel approximately horizontally. When the panel is moved from the guide rail to the roof guide rail in the panel reversing box, the vertical guide rail that has entered the panel reversing box from the guide rail is The panel in this state is inverted to a substantially horizontal state where the inner panel surface facing the indoor side between the guide rails becomes the lower surface at the roof guide rail section, and when the panel is moved from the roof guide rail section to the guide rail. A panel reversing means is provided for reversing the horizontal panel that has entered the panel reversing box into a vertical state where the lower surface thereof becomes the inner panel surface on the indoor side. The panel shutter reversing drive device according to claim 2 of the present invention connects a panel connection link plate that protrudes radially outward on the circumference of the panel drive system sprocket to the panel attachment portion of the panel connection chain. Both sides of each panel are rotatably connected and suspended via long pins on the outwardly projecting end side of this panel connecting link plate.

[For use]

In the panel shaft reversing drive device according to claim 1 of the present invention, the vertical panel that has ascended from the guide rail into the panel reversing box is moved between the guide rails so that the inner panel surface facing the indoor side is connected to the roof guide rail. Then, when moving the panel from the roof guide rail section to the guide rail, the horizontal panel that has entered the panel reversal box is inverted so that its bottom surface is on the indoor side. Since the inner panel surface of each panel is turned over vertically to become the inner panel surface of the panel, the inner panel surface of each panel does not become the outer surface (upper surface) at the roof guide rail section and is exposed to the wind and rain and becomes dirty. When the guide rail transition between the roof guide rail section and the above guide rail is closed, the panel surface that was the bottom surface of the above roof guide rail section will be changed to the interior side of the room between the above guide rails. It can be used in a suitable state as a side surface. Furthermore, the space between the guide rails and the roof guide rail section can be opened and closed alternately, making it possible to eliminate the need for a panel storage box, which is indispensable in conventional panel shutter devices. In the panel shutter reversing drive device according to claim 2 of the present invention, the panel connecting link plate is connected to the panel attaching portion of the panel connecting chain and protrudes radially outward on the circumference of the panel drive system sprocket. By rotatably connecting and suspending both sides of each panel through long pins on the protruding end side, a predetermined offset distance is set between the chain and the long pin, so that the panel connection In the process of the link plate moving on the circumference of the panel drive system sprocket, a circumferential speed difference occurs between the chain and the long pin, which causes
The long pin moves faster than the moving speed of the chain, and the panel suspended by the long pin is smoothly transported along the sprocket, and there is no risk of collision with subsequent panels.

【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings. In Fig. 1, reference numeral 1 denotes a pair of left and right guide rails that are placed upright on both sides of a shutter opening/closing opening, which is the entrance/exit of a building such as a store. An outer guide rail 3 is connected thereto which extends into the arcade forming area. In the panel reversing box 2, as shown in the third figure, a driving sprocket 4 and a driven sprocket 5 of the panel drive system are rotatably supported. The main drive sprocket 4 is driven to rotate in forward and reverse directions by a motor 40 disposed within the panel reversing box 2. Here, an example of the interlocking structure of the motor 40 and the main drive sprocket 4 will be explained with reference to FIGS. 3 and 8. An output sprocket 41 is fitted to the output shaft of the motor 40, and an intermediate input sprocket 43 and an intermediate output are attached to an intermediate transmission shaft 42 rotatably supported between the motor 40 and the main driving sprocket 4. A sprocket 44 is coaxially connected, and an input sprocket 45 is fitted onto the rotating shaft of the driving sprocket 4. A first transmission chain 46 is wound and meshed with the output sprocket 41 of the motor 40 and the intermediate manual sprocket 43, and a second transmission chain 47 is wound and meshed with the intermediate output sprocket 44 and the manual sprocket 45. ing. As a result, the driving sprocket 4 is driven to rotate in the forward and reverse directions by driving the motor 40 in the forward and reverse directions. Further, the guide rail 1 and the outer guide rail 3 are attached to the main drive sprocket 4 and the driven sprocket 5.
A pair of left and right panels connecting chains 6 are engaged with each other. Therefore, the driven sprocket 5 is connected to the chain 6.
The sprocket 4 is rotated as a result of the driving sprocket 4 through the sprocket 4. In the illustrated example, the driving sprocket 4 is located on the outer guide rail 3 side in the panel reversing box 2, and the driven sprocket 5 is located on the guide rail 1 side.
are placed above each other, but they may be placed in reverse. The panel linking chain 6 links a plurality of panels 7.8 that are driven to open and close in series along the guide rail 1 and the outer guide rail 3. As the connecting means, panel connecting link plates 61 (see FIGS. 3 to 5), which also serve as chain links, are connected in series at a predetermined panel connecting pitch to the panel attachment portion of the chain 6. . This panel connection link plate 61 is formed longer outwardly than the normal link plate 60 of the chain 6, and has a shape that projects outward in the radial direction on each circumference of the panel drive system subrocket 4.5. The structure is as follows. The panel connecting link plate 61 has a base end attached to the normal link plate 60 with a normal link pin P.
1 is connected by caulking. Further, a long pin P2 is rotatably attached to the outwardly protruding end side (free end side) of the panel connecting link plate 61, and each of the panels 7.
A slightly upper part of the abdomen on both sides of the body 8 is rotatably connected and suspended. Here, an offset distance a is set between the link pin P1 and the long pin P2 of the chain 6, as shown in FIGS. 3 and 5. Therefore, in the process in which the panel connecting link plate 61 moves on each circumference of the panel drive system sprocket 4.5, a circumferential speed difference occurs between the chain 6 and the long pin P2, and the long pin P2 chain 6
(the circumferential speed of sprocket 4.5). Therefore, in the process in which the panel connecting link plate 61 of the upper panel 7 that has ascended along the guide rail l and entered the panel reversing box 2 moves on the circumference of the driven sprocket 5, the upper panel 7 The moving speed becomes faster than the rising speed of the subsequent lower panel 8. Therefore, the lower panel 8 will not collide with the upper panel 7. When each of these panels 7.8 is in a vertical position between the guide rails 1, upper guide rollers R1 for preventing vibration are rotatably supported on both sides of the upper ends of the panels 7.8. Further, lower guide rollers R2 are rotatably supported at the lower portions of both sides of each panel 7.8 via roller brackets 9 (see FIGS. 3 and 5 to 7). As shown in FIGS. 6 and 7, this panel 7.8 has guide openings 1a for the guide rail 1 and the outer guide rail 3 on both sides thereof, respectively. 3a so as to be slidably fitted and engaged. Here, the guide rail 1 and the outer guide rail 3 are
The detailed structure of is explained below. First, as shown in FIG. 6, the guide rail 1 is formed of a hollow member having the guide opening 1a on its opposing surface, and has a vertical roller guide 10 and a chain presser plate 11 inside.
12 are arranged respectively. The vertical roller guide 10 is constructed by rolling the upper guide roller R1 in sliding contact with the inner wall surface on one side of the guide rail 1 while the lower guide roller R2 is in sliding contact with the inner wall surface on one side of the guide rail 1 when the panel 7.8 moves up and down. It performs the function of stably performing the lifting and lowering operations of 7.8. The chain holding plates 11 and 12 function to slidably sandwich the chain 6 and guide it smoothly. On the other hand, the outer guide rail 3, as shown in the first diagram,
A horizontal rail section (roof guide rail section) 31, a curved rail section 32, and a vertical rail section 33 extending to the roof forming area of the arcade are constructed in series, and the lower guide roller is installed inside the rail section as shown in Figure 7. A U-shaped roller guide 13 that slides and rolls R2, and chain press plates 14 and 15 that slidably sandwich and guide the chain 6 are arranged. Here, in the process of moving the panel 7.8 from the guide rail l to the outer guide rail 3 through the inside of the panel reversing box 2, the panel 7.8 is moved inside the panel reversing box 2 as described later. By being reversed (changed in direction) from the vertical state to the horizontal state, the lower guide roller R2 becomes in an upwardly protruding state, and as the lower guide roller R2 is guided by the roller guide 13, the roller guide 13 especially To stably move the panel 7.8 on the horizontal rail part 31. Also, inside the panel reversing box 2, as shown in the third figure, there is a sprocket guard plate 16 and a chain presser plate 1.
7 to 19 are arranged. The sprocket guard plate 16 functions to smoothly and reliably engage and separate the chain 6 with the panel drive system sprockets 4 and 5. The chain holding plates 17 to 19 are connected to the guide rail l.
A chain guide path 20 is formed which connects the inner chain retainer plate 11.12 and the chain retainer plate 14.15 within the outer guide rail 3. In addition, near the panel entrance of the guide rail example in the panel reversing box 2, a lower guide roller R2 of the panel 7.8 that has entered the panel reversing box 2 is tilted toward the outer guide rail 3. Panel guide plates 21, 22 are arranged to guide upwards. Further, above the driven sprocket 5 in the panel reversing box 2, when the panel connecting link plate 61 of the panel 7.8 that has ascended from the guide rail I reaches the driven sprocket 5, A panel reversing guide plate 23 is arranged for abutting the upper end of the panel 7.8. That is, from the guide rail 1 to the panel reversing box 2
When the panel connecting link plate 61 of the panel 7.8 that has entered the interior reaches the vicinity of the driven subblock throat 5, the lower guide roller R2 moves the panel guide plate 21.22.
As a result, the panel 7.8 rotates and tilts counterclockwise in FIG. 3 about the long pin P2. Next, at the time when the panel connecting link plate 61 bypasses the driven sprocket 5, the upper end of the panel 7.8 comes into contact with the panel reversing guide plate 23, so that the panel 7.8 maintains its vertical position when raised. The panel 7.8 is reversed (changed in direction) from the horizontal position to the horizontal position, and the panel 7.8 in the horizontal position is fed into the horizontal rail section 31 of the outer guide rail 3. Further, the link plate 61 for connecting the panel 7.8, which has entered the panel reversing box 2 in a horizontal state from the horizontal rail section 31, is attached to the guide plate 23 for reversing the panel. When you reach Nod 4,
A locking step 23a is provided for abutting and engaging the front end of the panel 7.8 in the direction of travel. This retaining step portion 23a functions to reverse the panel 7.8, which has entered the panel reversing box 2 from the horizontal rail portion 31 in a horizontal state, into a vertical state as described above. Therefore, the panel reversing guide plate 23 constitutes reversing means for reversing the panel 7.8 from the vertical position to the horizontal position and from the horizontal position to the vertical position. In the above, each panel 7.8 completely closes the guide rail 1, closes the space between the horizontal rail parts 31 which becomes the roof guide rail part, and opens the space between the vertical rail parts 33, or When the guide rails 1 are fully closed, the connecting length is such that the outer guide rails 3 (horizontal rail portion 31 and vertical rail portion 33) are opened. Next, the operation will be explained. When the main sprocket 4 is driven to rotate in the clockwise direction in FIG. As the meshed chains 6 move toward the outer guide rail 3, the panels 7, 8 between the guide rails 1 rise vertically in close contact with each other and sequentially enter the panel reversing box 2. In this case, when the upper panel 7 that has entered the panel reversal box 2 reaches the driven sprocket 5 during the rising process, the long pin P2 is attached to the chain on the circumference of the driven sprocket 50. Due to the difference in circumferential speed between the driven sprocket 5 and the driven sprocket 5, the driven sprocket 5 moves faster than the circumferential speed of the driven sprocket 5. Therefore, in the process of the long pin P2 moving along the circumference of the driven sprocket 5, the lower panel 8 moves to the upper panel 7.
There is no risk of collision and interference. In the process in which the long pin P2 moves along the circumference of the driven sprocket 5, the lower guide roller R2 of the upper panel 7 is guided obliquely upward by the panel guide plates 21 and 22, so that the upper panel 7 rotates and tilts counterclockwise in FIG. 3 about the long pin P2. At approximately the same time, the upper end of the upper panel 7 abuts and engages with the panel reversing guide Fi, 23. In this state, as described above, link play for connecting panels) 6
1 is the driving sprocket 4 on the circumference of the driven sprocket 5
By moving past the side, the upper panel 7 is horizontally reversed. In this case, the upper panel 7 is inverted approximately 90' between the guide rails 1 so that the inner panel surface 7a of the upper panel 7, which is on the indoor side of the building, becomes the upper surface. In this way, each panel 7.8 that has entered the panel reversal box 2 one after another is reversed from a vertical position to a horizontal position. Each panel 7.8 that has been inverted horizontally moves sequentially from the panel inversion box 2 to the horizontal rail section 31 of the outer guide rail 3, and then sequentially moves from the horizontal rail section 31 to the vertical rail section 33. do. In this case, the chain 6 is guided by the chain guide path 20 in the panel reversing box 2, and also in the outer guide rail 3 by the chain presser plate 14.1.
5, the panel 7.degree. 8, which has been inverted horizontally as described above, moves smoothly on the outer guide rail 3 by the chain 6. In this way, the panels 7° 8 between the guide rails 1 sequentially enter the panel reversing box 2, are reversed to a horizontal state, and moved to the outer guide rail 3.
At the same time as the space between the guide rails 1 is opened, the space between the outer guide rails 3 is closed. Therefore, when the spaces between the guide rails 1 (the entrances and exits of the building) are opened, the spaces between the outer guide rails 3 are closed to perform the function of an arcade. When the driving sprocket 4 is driven to rotate in the reverse direction from this state, the front end in the advancing direction of the panel 7.8, which has entered the panel reversing box 2 in a horizontal state from the horizontal rail section 3 of the outer guide rail 3, is reversed. guide plate 23
At this point, the panel connecting link plate 61 moves and passes on the circumference of the driving sprocket 4, and in the process of movement, the panel 7.8 is brought into contact with the long pin P2. It rotates clockwise in FIG. 3 around , and flips to the vertical position. Then, the panels 7.8, which have been reversed to the vertical state, are sequentially rolled out between the guide rails 1, closing the space between the guide rails 1, and at the same time opening at least the space between the vertical rail portions 33 between the outer guide rails 3. In the above embodiment, the case where the present invention is applied to an arcade has been described, but it can also be applied to other uses such as a sunroom. Further, the outer guide rail 3 may consist only of the horizontal rail portion 31 which becomes the roof guide rail portion.

【Effect of the invention】

As described above, according to the present invention, the conventional panel storage box is not required, and the outdoor roof can be opened and closed as well as the entrance and exit of the building, and the roof can be opened and closed from between the guide rails. When moving the panel to the guide rail section, flip the panel so that the inside panel surface facing indoors between the guide rails becomes the bottom surface at the roof guide rail section, and move the panel from the roof guide rail section to between the guide rails. When moving, the panel is reversed so that the inner side of the roof and the panel side are on the indoor side between the guide rails, so the panel surface that has been exposed to the wind and rain on the roof guide rail will be on the outside side even between the guide rails. This means that the interior side of the room will always have a clean panel surface, so there is no risk of causing discomfort to residents, etc. (However, the product value will be greatly improved, and it can also be applied to arcades, sunrooms, greenhouses, etc.) This has the effect of making it highly versatile.
