[Problem that the idea aims to solve]

With such a revolving window opening/fixing device, the shoji can be rotated from the closed position to the open position. When opening the shoji, the connecting shaft engages with the multiple locking holes in the guide stopper in sequence, allowing the shoji to be opened to its maximum. In order to rotate to the release angle, the engagement between the connecting shaft and the locking hole must be released multiple times. In the case of a revolving window installed at an emergency entrance, quickly rotate the shoji to the maximum opening angle. If the above-mentioned revolving window opening/fixing device is used, multiple A release operation is required, which makes the operation cumbersome and time-consuming. In order to solve this problem, the guide stopper should be shaped to have one locking hole. If you do this, you will not be able to adjust the opening angle of the shoji in stages. In other words, with revolving windows, the opening angle of the shoji can be adjusted in stages depending on the purpose. There are some that rotate only to the maximum opening angle, and conventional rotating window opening fixing devices. Therefore, a different opening and fixing device is required for each rotating window depending on its use.
