[Effect of idea]

According to the present invention, a fixed rail that guides and suspends a plurality of shutters in parallel is disposed horizontally, and a plurality of shutters are connected to the fixed rail via a support shaft on an extension line of at least one end of the fixed rail. A movable rail for suspending the rain shutters in a stacked state is mounted so as to be horizontally rotatable, and an engaging recess is formed on one end of the fixed rail on the movable rail,
A cover body having an engagement recess formed at the other end in the rotational direction of the movable rail and an arc-shaped guide section formed between the two engagement recesses is fixed, and the cover body is fixed to one side of the movable rail. It has a latch roller that engages with a guide portion in both the engagement recesses and between the two engagement recesses, and a release protrusion that can move back and forth to release the engagement of the latch roller when pushed by the pushing protrusion of the shutter. Since a latch mechanism with two pieces is installed, the connection position of the movable rail that rotates around the support shaft with respect to the fixed rail, and the separation position of the movable rail when the movable rail rotates far away from the fixed rail are located in both engagement recesses of the cover body. It is possible to accurately and reliably position and hold the shutter by engaging the latch roller of the latch mechanism by moving it forward and backward, thereby ensuring that the shutter suspended on the movable rail is not rocked by external pressure. In addition, the shutters can be hung with good stability, and the positioning of the movable rail in each of the above cases can be performed automatically in connection with the movement of the shutters, making the opening and closing operations easy. At the same time, there is no chance of forgetting to apply the anti-tilt mechanism, smooth transition of the shutter between the fixed rail and the movable rail, and furthermore, the latch mechanism and the movable rail can be reliably covered and protected by the cover body. It is possible to reliably prevent these from becoming inoperable due to rusting, etc., and therefore,
In addition to being able to always smoothly open and close entrances and exits using multiple shutters, we have developed a shutter opening/closing device that is easy to handle and operate, as well as allowing the openings to be opened completely and at any angle. can be provided.
