Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a shoji slip-off prevention device that is attached to the lower surface of the upper frame of a sliding window in order to prevent the shoji from falling off the window frame.

(Prior art) As a device to prevent this type of shoji from coming off,
A device disclosed in Japanese Patent No. 2845 is known. This retaining device fixes a fixing member with a threaded portion to the upper frame, screws a retainer with a female thread onto the fixing member, and rotates the retainer to adjust the height of the retainer. It is used to adjust the

With this device, the height can be adjusted over a wide range, so even if the upper frame sags or warps upward, it can sufficiently absorb the displacement and maintain the function of preventing the shoji from coming off. I can do it.

(Problem to be solved by the invention) However, in the conventional shoji locking device, the fixing member and the locking tool are screwed together, so when the shoji is slid open and closed, vibrations occur when the shoji is running. When the window frame and the shoji collide, the screws may loosen due to the impact, causing the height of the stopper to change or causing the shoji to fall off.

Further, although the fixing member and the stopper are generally made of hard synthetic resin, if the shoji hits the stopper strongly, there is a risk that the screw threads will collapse.
When the height of the retaining device is increased and the amount of screw engagement between the fixing member and the retainer is reduced, there is a particular risk that the two may separate.

This invention solves the above-mentioned problems and provides a shoji shoji retaining device that can adjust the height of the shoji retainer in stages and exhibits a reliable retaining function at any height. The purpose is to

(Means for solving the problem) In order to achieve the above object, the base body 10 and the locking body 20 are opposed to each other, and one member has a pivot 5 in the center.
