Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shoji locking device for locking a bathroom folding door in a closed state.

[Conventional technology]

Various types of shoji locking devices are known for locking folding doors in a closed state.

For example, as shown in Japanese Utility Model Application No. 59-74268,
A long locking member is slidably inserted into the matching frame of the shoji between a locking position protruding from the matching frame and a release position housed within the matching frame, and a spring is installed inside the matching frame. A locking device that engages with a recessed portion of a locking member to hold the folding door in the locked position and the released position, and when the locking member is set to the locked position, it engages with the door frame and locks the folding door in the closed state.

As shown in Japanese Utility Model Application Publication No. 57-84262, the lock member has a shape in which a lock piece and a sliding piece are connected, a ball and a spring are provided on the sliding piece, and a hole for engaging the ball is provided in the matching frame. A locking device for a folding door is known in which a lock piece is held in a locked position and a released position by engaging a ball in the hole.

[Problem that the invention attempts to solve]

In such a locking device for a folding door, in order to hold the locking member in the locked position and the released position, members such as springs, balls, and springs are assembled and installed in the frame or on the locking member, and recesses and holes are inserted into the locking member. Since the structure is formed into a stile or a matching frame, the number of parts increases, which not only increases the cost but also makes the assembly work troublesome.

In particular, the former locking device requires a spring to be installed inside the matching stile, which is very troublesome and makes assembly work difficult, while the latter locking device requires two holes to be drilled in the matching stile, making the work very laborious. This makes assembly work troublesome.

Therefore, an object of the present invention is to provide a shoji locking device that can reduce the number of parts and can be easily assembled without troublesome installation work or troublesome processing work.

[Means and actions for solving problems]

A lock member with a locking piece inside the matching frame,
The locking piece is slidably inserted between a lock position and a release position, and a locking recess is formed in the locking piece to engage with the head of a screw connecting the matching stile and the horizontal stile of the shoji. The locking member can be held in the locked position and the released position by using screws that connect the connecting frame and the horizontal frame.
