BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for locking a shoji in a closed window state in a swinging open / close window in which a wire sequentially wound around a pulley attached to a frame of a frame is wound around a drum to close the window.

2. Description of the Related Art Problems to be Solved by Conventional Techniques and Inventions Conventionally, as a window locking device for a swing opening / closing window of this type, a pair of pinching bodies having a wedge-shaped biting portion opposed to and protruding from a window frame. While fixing one side and swinging the other side so as to oscillate freely and urge in the clamping direction, the shoji has a fitting plate that is fitted between the two clamping bodies, and the fitting plate is fitted when the window is closed. Is inserted between the two pressure plates, the insertion plate is pinched between the two pressure plates so that the biting part bites into the pinching plate to prevent it from coming off, so that the locking plate is locked in the closed window state, and the window opening is performed. At times, it is known that the lock is released by pulling a wire for unlocking, which is different from the one for opening and closing the shoji, to separate the pinching body on the movable side from the fitting plate. With such a conventional device, as the number of times of use increases, the biting part of the pressing member and the pressed surface of the fitting plate become worn. The locking plate may slip out between the two clamping plates even when locking, and the locking function may not be achieved.When the window is opened, the latch of the winding drum should be removed so that the wire for opening and closing the shoji can be operated. In addition to the operation, it is necessary to pull the wire for unlocking the shoji screen, so that the window opening operation is troublesome.

As means for solving the above problems, as a means for solving the above problems, the rocking window locking device for a swing opening / closing window according to the present invention mounts a shoji on a window frame so that the shoji can be freely opened and closed. The window was urged to close the window by winding the wire sequentially wound on the pulleys attached to the open side frame of the shoji screen and the frame of the window frame corresponding to the frame by the pulley. In the swing opening / closing window, a fitting plate having a hooking hole is provided on either one of the open side frame of the shoji screen and the frame of the window frame corresponding to the frame so as to project toward the other side, and the other side , A claw plate that has a fitting part at the tip that fits into the locking hole of the locking plate is provided around the axis in the direction perpendicular to the direction of entry in the direction of entry of the locking plate when the shoji screen is closed. The lock position where the fitting part approaches the approach road,
A mounting body that is swingably supported between the lock release position and the upper side of the approach path is attached, and the claw plate is swingably biased to the lock position, and the pulley is attached to the open side frame of the mounting body. The frame and the frame are freely supported in the advancing / retracting direction, and are always biased in the backward direction, and the tension applied to the wire by winding the wire further after closing the window of the shoji moves forward against the backward biasing force. When the pulley moves backward, it engages with the engaging portion of the claw plate to swing the claw plate to the lock release position against the swinging urging force. An actuating member is provided so as to project the claw plate to the rocking position by a rocking biasing force by separating the claw plate.

The operation and effect of the present invention With the above configuration, when the wire is wound around the drum from the open window state, the open side frame of the shoji gradually approaches the corresponding frame of the window frame, and the hanging plate protruding on one side. Is closed while entering the opponent's approach road, the shoji hits the window frame, the hook plate has advanced to a predetermined position on the approach road, and the shoji closed completely, and then wound up the wire, While the shoji cannot close the window any further, the pulley on the mounting body is supported so that it can move forward and backward, so that the pulling force acting on the wire causes the pulley to move forward against the backward biasing force. To the position, and accordingly, the actuating member projecting from the pulley of the pulley advances so as to move away from the engaging surface of the claw plate, and the claw plate retracted to the lock release position is locked by the rocking force. It swings to the position, and the fitting part at the tip fits into the locking hole to lock it. When the plate is hooked and the pulling force of the wire is maintained by blocking the rotation of the drum in the feeding direction by the latch member, etc., the hooking of the fitting plate by the claw plate is maintained and the shoji block is locked in the window closing state. , When the window is closed and the drum is allowed to rotate in the feeding direction, the pulley supported by the mounting body returns to the retracted position while feeding the wire by the backward biasing force, and the operating member retracted together with the pulley engages the claw plate. And the claw plate is rocked to the lock release position against the urging force of the swing plate, and the lock is released by the fitting part coming out of the latch hole of the latch plate. Then, the latch plate retracts from the approach path, and the wire is further extended from the drum, and the shoji opens.

As described above, according to the present invention, the engaging portion of the mating claw plate is fitted into the engaging hole of the engaging plate projecting from the open side frame of the shoji screen and the frame of the window frame corresponding to the frame. As a result, unlike the conventional device, there is no risk of slipping off due to the progress of wear of the engaging portion, and it is possible to reliably lock the shoji over a long period of time, and to open the window. At this time, if you perform an operation that allows rotation of the drum in the feeding direction, the lock of the shoji will be automatically released, so you can open the window with one tap without performing a special operation to release the lock. effective.
