Description

[Detailed Description of the Invention] The present invention relates to a device for preventing a shoji such as an aluminum sash screen door from coming off a window frame.

As described in Japanese Utility Model Publication No. 55-43896, the conventional device of this kind is to erect a shoji on a window frame and then raise the retaining piece attached to the vertical stile of the shoji to remove the rail on the upper frame. By engaging the shoji with the shoji, the shoji was able to fit into the window frame of the shoji without coming off.

However, with such conventional devices, after the shoji is built into the window frame, the locking piece is fixed with screws using the elongated holes in the vertical stile and the locking piece so that it protrudes from the upper end of the vertical stile. Therefore, since the retaining pieces are fixed to the shoji, it is necessary to fix the detachable pieces every time the shoji is put up, which is very troublesome, and it is easy to forget to fix the retainers. Things were also hot. Another problem was that when this device came off the lower frame, the retainer also came off the upper frame, causing the shoji to come off the window frame.

Therefore, the present invention can automatically prevent the shoji from falling off at the same time as installing the shoji, and even if the lower stile of the shoji comes off the lower frame, the shoji will be prevented from coming off the window frame. The purpose of the present invention is to provide a device for preventing the shoji from coming off.
