Description

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

The present invention relates to a push-up two-panel shutter device for opening and closing shutter openings such as entrances and exits of buildings, windows, and shutters.

[Conventional technology]

In the conventional panel shank device, a puffle storage box is placed on the top (ceiling side) of guide rails that are placed upright on both sides of the opening for opening and closing the shutter on the floor. A normally configured chain is engaged with the driving sprocket, and the chain connects multiple stages of upper and lower panels that are driven up and down between the guide rails, and by starting the sprocket to rotate in one direction,
By moving each panel downward from inside the panel storage box along the guide rail, the shutter opening/closing opening is closed, and from this state, by starting the sprocket to rotate in the other direction, the guide rail is closed. Each panel in between is raised and stored in the panel storage box.

[Question B that the invention attempts to solve]

Since the conventional panel shutter device is configured as described above, when closing the shutter, the panel is lowered between the guide rails from within the panel storage box placed on the ceiling side at the upper end of the guide rail. For example, if the panel that is being lowered does not come down to the pedestrian's line of sight, the pedestrian will not be able to tell that the panel is in the lowering operation. This poses a problem in that it is extremely dangerous as it can lead to accidents caused by people crossing the opening/closing opening. In addition, in the conventional panel shutter device described above, the panels are suspended between the guide rails by a chain meshed with a sprocket in the panel storage box, so if the chain breaks, there is no chance of the panel falling. There was a problem with the risk of inviting This invention was made to solve the above-mentioned problems, and it is possible to easily check the closing operation of the panel, and it is safe so that the panel will not fall even if the panel linking chain breaks. The object of the present invention is to provide a push-up two-panel shutter device that is rich in properties.

[Means to solve the problem]

The push-up panel shutter device according to the present invention includes a panel storage box installed under the floor or underground, and a pair of left and right panels that are connected to the panel storage box and stand on both sides of the shutter opening/closing opening on the floor or above ground. A guide rail, a plurality of upper and lower panels that are movable up and down along the guide rail and that are suspended and stored in a parallel folded state within the panel storage box, a chain that interconnects these panels, and the panel. A sprocket for pushing up the panel is arranged in the storage box and meshed with the chain, and when the shutter is closed, the sprocket is rotationally driven to push the panel in the panel storage box up between the guide rails. It is designed to be fed out. Further, a panel connection link attachment that protrudes radially outward on the circumference of the sprocket is integrally connected to the panel attachment portion of the chain, and the radially outward protruding end of the link attachment Each of the panels is rotatably suspended by a long pin in the chain, and a predetermined offset distance is set between the chain and the long pin.

[For use]

In the push-up panel shutter device according to the present invention, the panel is pushed up from within the panel storage box placed under the floor or underground between the guide rails on the floor or on the ground, so that the push-up and closing operation of the panel can be avoided by pedestrians, etc. This eliminates the danger of pedestrians injuring themselves by inadvertently touching the panel while it is rising. Moreover, by having the structure in which the panel is pushed up as described above, the danger of the chain breaking and the panel falling as in the conventional case is eliminated.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. 1 to 4, I is a panel storage box (hereinafter referred to as storage box) installed under the floor near the opening for opening and closing the shutter; 1a is a panel entrance that opens at the upper end of one side of the storage box 1; 2 is the panel entrance 1a
A pair of left and right guide rails are connected to and stand up on both sides of the shutter opening/closing opening on the floor, and these guide rails 2 are each made of a U-shaped member having an opening for guiding the panel up and down on each opposing surface side. ing. The guide rail 2 has a plurality of upper and lower panels 3 for opening and closing shutter openings between the guide rails 2.
．． 4 are fitted and engaged so that they can move up and down, and the panels 3 and 4 can be moved into the storage box 1, where they are suspended and stored in a parallel folded state. It is now possible to do so. Each of the panels 3 and 4 is connected at both upper sides by a chain 5 via a link attachment 6. On the other hand, inside the storage box 1, there is a panel entrance 1.
A sprocket 7 for driving the panel up located near a, and a chain engagement/separation device 8 for forcibly engaging and forcibly separating the chain 5 from the sprocket 7.
A support rail 9 for suspending and storing the panel is connected to the end of the chain engagement/separation device 8 in the panel storage direction and is arranged substantially horizontally. Here, the chain engagement/separation device 8 includes a chain press plate 81 disposed close to the outside of the tooth tip of the sprocket 7 and a sprocket guard plate 82 disposed close to the inside of the tooth tip of the sprocket 7. It consists of a combination of a chain holding plate 81 and a sprocket guard plate 82.
A chain guide path 83 is formed between which the chain 5 is inserted and guided. The chain guide path 83 has a curved guide portion that curves the chain 5 hanging down from within the guide rail 2 toward the support rail 9 and meshes with the tip of the sprocket 7 inside the curved portion. There is. In addition, in the chain guide path 83, on the side of the chain presser plate 81 on the outside thereof, there is a plate that slides and rolls on the chain 5 on the outside of the curved part of the chain 5 to smoothly move the chain 5 in a predetermined direction. Rotation guides such as bearings and rollers may be arranged in an axis-dominated array. Next, the means for connecting the panels 3 and 4 using the chain 5 will be explained. A base portion of a link attachment 6 is integrally connected to the panel attachment portion of the chain 5 via a link pin P1 in that portion. This link attachment 6 has a shape that projects on the circumference of the sprocket 7 toward the outer surface in the radial direction of the sprocket 7 when the sprocket 7 and the chain 5 are engaged with each other, and has a long pin at the projecting end. P
2, both upper sides of each of the panels 3 and 4 are rotatably connected. Therefore, an offset distance a is set between the link pin P1 of the chain 5 and the long pin P2. Due to this offset distance a, in the process in which the link attachment 6 moves on the circumference of the sprocket 7, a circumferential speed difference occurs between the chain 5 and the long pin P2, and the panel 3 or 4 moves along with the long pin P2. It will move at a speed faster than the moving speed of the chain 5 (the circumferential speed of the sprocket 7). Here, each of the panels 3.4 has a fitting protrusion 10 in the longitudinal direction of its upper end and a fitting groove 11 in the longitudinal direction of its lower end, and the guide The fitting protrusions 10 and the fitting grooves 11 of the panels 3 and 4 pushed up between the rails 2 fit together, and a gap is created between the panels 3 and 4. I'm trying to make sure it doesn't come to life. However, when the panels 3 and 4 are stored between the guide rails 2 into the storage box 1, the sprocket 7
If the fitting protrusions 10 and the fitting grooves 11 between the panels 34 that have descended close to each other remain fitted, they will not support the lower panel that has reached the sprocket 7 portion. Lateral feed to the rail 9 side becomes impossible. However, in this invention, as described above, the moving speed of the panel 34 together with the long pin P2 on the circumference of the sprocket 7 is faster than the moving speed of the chain 5, so that the support The upper end fitting convex strip 10 of the lower panel 3 moving toward the rail 9 side separates from the lower end fitting concave strip 11 of the upper panel 4, thereby causing the lower panel 3 to move toward the support rail 9 side. Transverse feed is performed smoothly. The long pin P2 of each panel 3.4 is provided with an upper guide roller R for rolling on the support rail 9 to suspend and store each panel 3.4 on the support rail 9.
is rotatably mounted. Next, the operation will be explained. First, in a state where each panel 3.4 is suspended and stored on the support rail 9 via the respective upper guide rollers R, when the sprocket 7 is rotationally driven in the direction of pushing up the panel, the sprocket 7 engages with the sprocket 7. With the chain 5 the panels 3.4 on the support rail 9 are pulled one after the other. As a result, the upper end of each panel 3.4 successively reaches the sprocket 7 and passes through the sprocket 7 along its circumference, thereby being pushed up between the guide rails 2. At this time, the panel that has passed the sprocket 7 is pushed up by the chain 5 or the lower panel,
When the panels 3.4 are pushed up, the fitting protrusions 10 and the fitting grooves 11 between the panels 3.4 fit together, and all the panels 3.4 are pushed up between the guide rails 2, so that the guide rails 2 are pushed up. The space between rails 2 is completely closed. When the sprocket 7 is reversely driven from this fully closed state, the panels 3 and 4 between the guide rails 2 sequentially descend and enter the storage box 1, and the panels 3 and 4 passing through the sprocket 7 in the panel storage direction 4 is link bin P
1 and the long pin P2 move faster than the upper panel due to the offset distance gIa, and as a result, the fitting between the fitting protrusion 10 and the fitting groove 11 is released, and the long pin P2 moves toward the support rail 9, and the support rail At 9, the upper guide roller R moves and rolls to be suspended and stored. In this case, the panel that has moved onto the support rail 9 is pushed in the storage direction by the subsequent panel.

【Effect of the invention】

As described above, according to the present invention, a panel is pushed up from within a panel storage box placed under the floor or underground between the guide rails on the floor or on the ground. etc. can be easily confirmed, thereby eliminating the risk of injury from pedestrians accidentally touching the panel during the rising operation.In addition, by having the structure of pushing the panel up as described above, This eliminates the danger of the chain breaking and the panel falling as in the past, and provides a highly reliable push-up double panel shutter device that is highly safe.
