JP4441343B2 - Device for preventing misoperation of the shoji locking mechanism - Google Patents

Description

  The present invention relates to a locking mechanism for shojis such as windows and doors, and more particularly to an erroneous operation preventing device for shoji locking mechanisms that can prevent erroneous operation of the locking mechanism.

  A locking mechanism is used in which a shoji side engaging member is provided on the shoji, and an interlocking plate having a frame side engaging member on the shoji frame and an operation member for moving the interlocking plate are provided to lock the shoji (for example, , See Patent Document 1). According to this mechanism, when the interlock plate is moved through the operation member when the shoji is closed, the frame side engaging member can be locked by being engaged with the shoji side engaging member, and when the shoji is opened, the operation member is interlocked. The plate can be moved in the opposite direction, and the frame side engaging member and the shoji side engaging member can be disengaged and unlocked.

Normally, the operating member is configured to move the interlocking plate by rotating an operating piece such as a lever, and the lever can be rotated regardless of the position of the shoji, so that the shoji is not completely closed. In addition, the interlocking plate can be moved to the locking position via the operation member. In such a state, the shoji side engaging member and the frame side engaging member are not engaged with each other. For this reason, forgetting to lock or thinking that it is locked may cause an erroneous operation that it is not actually locked. . Patent Document 1 discloses an erroneous lock prevention means for preventing such an erroneous operation. The lock prevention means forms a notch in the moving member (interlocking plate) and engages with this. Since the stopper is provided on the window frame, the structure is complicated and difficult to obtain economically. Moreover, it cannot be incorporated into an existing locking mechanism afterward.
