General sliding windows and louver windows are configured to open and close shoji by operating an opening and closing mechanism such as an operator. However, since the conventional window opening/closing lock device is provided separately from the shoji opening/closing mechanism, when locking the window, the operator operates the handle or the like to close the shoji, and then opens and closes the window. A two-step procedure is required to operate the locking/unlocking lever of the locking device to lock the door. With such a configuration, there is room for improvement in terms of crime prevention, since it is possible that the user may forget to operate the window opening/closing lock device after closing the shoji.

The invention disclosed in the present application has been made in view of the above-mentioned circumstances, and an object to be solved is to provide a window opening and closing lock device that automatically locks when a shoji is closed, with a mechanism as simple as possible.

In order to achieve the above object, the window opening/closing lock device of the invention disclosed in the present application has a receiving tool attached to the projection part of the door frame of the shoji which is built into the window frame and opened and closed in the direction outside the opening plane. , the receiving member is formed with a groove extending in the length direction of the door frame and one end of which is open to the closing side of the shoji, while the opening of the window frame overlapping the door frame is formed with , a lock pin that engages and disengages with the groove hole of the receiving tool is assembled via an interlocking member that moves along the material length direction of the window frame, and the interlocking member is engaged with the lock when the shoji is closed. The shoji is locked by moving the pin to the "lock position" in which the pin is engaged with the slot of the receiver, and the interlocking member pulls out the lock pin from the slot of the receiver ("unlock position"). In the window opening/closing lock device in which the shoji can be opened and closed by moving to the above position, the window frame is provided with a biasing force in the direction of moving the interlocking member to the lock position side, and resists the biasing force. A locking mechanism is provided to temporarily fix the interlocking member at the unlock position, and when the shoji is closed, a trigger attached to the door frame of the shoji is locked and unlocked by the locking mechanism. A basic configuration is adopted in which the temporary fixing of the interlocking member is released by coming into contact with the cam, and the interlocking member is moved to the lock position by the biasing force.

According to this configuration, the interlocking member attached to the window frame side and temporarily fixed at the "unlocked position" is automatically locked to the receiver attached to the door frame of the shoji by the closing operation of the shoji. The shoji is locked by moving to the "locked position" where the pin is engaged. Therefore, it is possible to prevent a situation such as forgetting to lock after closing the shoji.

Further, in the window opening/closing lock device of the invention disclosed in the present application, in addition to the basic structure described above, the locking/unlocking cam is pivotally mounted to the interlocking member so as to swing in the opening/closing direction of the shoji.

A specific configuration is employed in which the hook is disengaged from the engaged portion to release the temporarily fixed state. By adopting this rational and simple mechanism, the operation of closing the shoji becomes smoother and reliable operability is obtained.

Further, in the above configuration, the locking/unlocking cam is attached to the interlocking member via a cam attachment member, and an urging member that applies the urging force between the cam attachment member and the cam receiving member. is attached.

Further, the window frame is provided with an unlocking mechanism for moving the interlocking member at the locking position to the unlocking position side by operating a lever, and the locking/unlocking cam moves in conjunction with the operation. The engaging hook of the locking/unlocking cam may be engaged with the engaged portion by moving the receiving member within the cam guide portion. As a result, the shoji can be opened with a simple operation.

Further, the trigger is held so as to swing toward the closing side of the shoji through a trigger mounting plate attached to the door frame of the shoji, and when the shoji is opened, the cam guide portion is operated. Contacting the passive piece of the locking/unlocking cam that is hooked from the closed side of the shoji, it can move to the open side of the shoji while rotating so as to get over the passive piece. .

Further, the locking mechanism may incorporate a damping member that reduces the speed when the interlocking member moves from the unlocked position to the locked position.

According to the window opening and closing lock device disclosed in the present application, when the shoji is closed, the lock pin attached to the window frame automatically engages with the receiving tool attached to the shoji to lock the shoji in the closed state. , the situation of forgetting to lock after closing the shoji can be prevented.
