[Detailed description of the device] [Industrial applications]

The present invention relates to a panel-type shutter device that opens and closes a shutter opening / closing opening such as a doorway or a window of a building by a plurality of connecting panels.

[Prior art]

Conventional panel shutters consist of a pair of left and right guide rails standing upright on both sides of the shutter opening / closing opening, a box for panel storage placed above these guide rails, and a guide rail inside the box. A pair of right and left chains that are movable to each other, both sides of which are flexibly linked and mounted between the guide rails, and a sprocket for driving the panel that is disposed in the box and meshes with the chain. By rotating the sprocket, the panels are moved up and down through the chain, and the panels are pulled out to a deployment closed state in which they are adjacent to each other in the same vertical plane between the left and right guide rails. In the box, they are suspended and held in parallel. Here, in the box, there is arranged a support rail that movably supports the upper end of each panel by gradually descending in a direction away from the entrance and exit, and a panel that has entered the box in a vertical attitude is placed in a vertical attitude. As it is, it is suspended by the above support rails.

[Problems to be solved by the device]

The conventional shutter device is configured as described above, and merely suspends the panel that has entered the panel storage box with the support rail in the vertical posture, and the support rail is the panel storage box. Since the panel that has entered inside is tilted to move in the storage direction by its own weight, it is said that the height dimension of the panel storage box must be increased in consideration of the inclination and the height of the panel. There was a problem. In this way, when the height of the box for storing the panel becomes large, the opening height of the entrance is restricted when the shutter device is housed in the ceiling in a store or when the ceiling is low,
There are problems that the shutter installation places are limited and that the aesthetic appearance of the entire shutter device is impaired. The present invention has been made to solve the above problems, and the height of the panel storage box can be reduced without changing the height of each panel. It is an object of the present invention to provide a shutter device that can smoothly store and unwind a panel in and from the panel.

[Means for Solving the Problems]

In the shutter device according to the present invention, the panel that has entered the box is transferred to the support rail along the sprocket, the panel moves along the support rail toward the panel storage direction, and the lower guide roller is moved to the panel. A panel lower guideway that guides to the storage direction side and a panel lower guideway that is provided near the inclined top of this panel lower guideway and is guided by the panel lower guideway in the process of laterally moving to the panel storage direction side. By temporarily engaging the lower guide roller and letting the lower guide roller escape downward, the upper guide roller precedes the lower guide roller, and a roller escape portion for tilting the panel, and a panel accommodation from the roller escape portion. Direction parallel to the lower side of the panel storage direction side of the roller escape portion. It is obtained by constituting a lower guide portion for rollably supporting the Idorora.

[Action]

In the shutter device according to the present invention, the upper guide roller of the panel that has entered the panel storage box during the panel storage operation is continuously transferred from the vertical movement along the sprocket to the horizontal movement toward the panel storage direction. The panel moves along the support rail toward the panel storage direction, and the lower guide roller is guided toward the panel storage direction along the panel lower guide path. The lower guide roller guided by the lower panel guide path temporarily engages with the roller escape portion and escapes downward, while the upper guide roller of the panel continues to move laterally on the support rail in the panel storage direction. To do.
As the lateral movement continues, the panel has an inclined posture in which the lower end of the roller is temporarily engaged with the lower guide roller, and the upper end of the panel is displaced from the lower end of the panel toward the panel storage direction. Become. In this way, the upper guide roller of the panel in the inclined posture moves on the support rail,
Further, the lower guide roller runs on the lower guide part by its own weight due to the inclination of the support rails and the lower guide, whereby the panel is transferred to the predetermined storage position in the inclined posture. As described above, since the panels are transferred and stored in the panel storage box in a tilted posture, the height dimension of the panel storage box can be made smaller than before, and the above-mentioned conventional problems can be solved.
