Description of the Related Art Conventionally, as a window locking device for a swinging opening / closing window of this type, a pair of pressure bodies formed by projecting a wedge-shaped cut-in portion facing a window frame, one of which is fixed, and the other is fixed. At the same time, it is mounted swingingly and urged in the pressing direction, and a fitting plate is fitted to the shoji to be fitted between the two pressing bodies. The fitting plate fits between the two pressing bodies when the window is closed. Then, the fitting plate is pinched between the two pressing plates so that the biting portion bites into the pinching plate and is prevented from being pulled out, so that the window is locked in a window-closed state. The lock is released by pulling a wire for use to separate a movable-side pressure body from an insertion plate.

る欠点があつた。However, the conventional device as described above, however, delicately adjusts the fitting device of the fitting plate to prevent a gap from being provided between the fitting plate and the fixed pressure plate when the window is closed. Not only does the mounting work take time, but also as the number of uses increases, the bite portion of the pressure body and the pressure-receiving surface of the insertion plate wear, and even when locking, the insertion plate There is a risk that the lock function cannot be performed by slipping out of the gap between the boards.In addition to the operation of removing the latch of the winding drum so that the wire for opening and closing the sliding door can be fed out when the window is opened, the wire for unlocking the sliding door is also used. There is a drawback that the fenestration operation is troublesome because it requires a pulling operation.

ばねの弾力に抗して前進位置へ移動させる構成とした。Means for Solving the Problems As means for solving the above-described problems, the locking device for a swinging opening / closing window of the present invention includes a locking member projecting from an outer peripheral surface of an open side frame of a shoji, A locking member that locks the locking body irreversibly on the inner peripheral surface of the frame of the window frame corresponding to the frame, near the approach path where the locking body enters when the sliding door is closed,
The lock member is movably supported between a lock position protruding into the approach path and a lock release position retracted from the approach path, and is disposed in a meshing groove formed in the lock member so as to freely advance and retreat in a direction perpendicular to the approach path. By engaging the toothed member and moving it forward and backward, the locking member is moved to the locking position and the unlocking position, and the wire feeding end is connected to the front end of the toothed member, and The other end of the extension coil spring, one end of which is fixed to the frame, is normally urged to move the toothed member to the retracted position by the elastic force of the extension coil spring, and further winding the wire after the window of the sash is closed. The configuration is such that the toothed member is moved to the advanced position against the elasticity of the tension coil spring by the tensile force applied to the wire.

置まで入り込んだ状態となる。Operation and effect of the invention In the fenestration state in which the wire is extended, since no tensile force acts on the wire, the toothed member is pulled to the retracted position by the elastic force of the tension coil spring, and is engaged with the wire. The combined locking members are retracted to the unlocked position. When the drum is rotated in the winding direction from this fenestration state, the wire is gradually wound around the drum while the toothed member is located at the above-described retracted position by the elastic force of the extension coil spring, and the wire projects into the open side frame of the shoji. When the provided locking body is closed on the corresponding frame while entering along the approach path and the shoji is hit by the window frame and the shoji is completely closed, the locking body enters a predetermined position on the approach path. State.

係止が維持されて、障子が閉窓状態にロツクされる。When the sash is further wound up from the state where it cannot be further closed, the toothed member is pulled to the advanced position while the tension coil spring is stretched against its elasticity by the tensile force acting on the wire. Accordingly, the locking member retracted to the unlocking position moves to the locking position in the approach path and locks the locking body irreversibly. Then, when the rotation of the drum in the feeding direction is prevented by the latch member or the like and the pulling force of the wire is maintained, the locking of the locking member by the locking member is maintained, and the sash is locked in the window closed state.

The toothed member together with the wire is pulled back to the retracted position by the restoring elastic force of the extension coil spring, the locking member moves to the unlocking position, and the locking is released by releasing the locking member from the locking member, and the locking is released. The window is opened while the wire is further fed out of the drum by the window urging force.

タツチで開窓操作を行うことができる効果がある。As described above, the present invention employs a structure in which the locking member protruding from the open side frame of the shoji is irreversibly locked by the locking member on the side of the window frame that moves into and out of the approach path. Even if there is a slight error in the road, the locking can be performed, and the mounting position of the locking body does not need to be adjusted with high precision. There is no risk of slipping off due to the abrasion of the sash, and the locking function of the shoji can be reliably performed for a long period of time. In addition, if the operation of allowing the rotation of the drum in the feeding direction is performed at the time of opening the window, the locking of the shoji is automatically released.Therefore, the window opening operation can be performed with one touch without any special operation for releasing the locking. There are effects that can be performed.

Normally, the geared cable 26 is pulled to the retracted position, the locking member 41 is retracted to the unlocked position shown by the solid line in FIG. 6, the shoji 3 is closed, and the locking of the shoji 3 is performed. When the body 40 advances to the front side of the step portion 42 of the locking member 41 and the wire 5 is further wound up from the state in which the shoji 3 is completely closed, the wire 5 resists the elasticity of the tension coil spring 35 by the tensile force of the wire 5. The geared cable 26 is pulled to the forward position, and the locking member 41 meshed with the geared cable 26 projects to the locking position in the approach path as shown by a chain line in the figure, and the locking body 40 is locked irreversibly. It is like that.

とする揺動開閉窓の閉窓ロツク装置A sash is mounted on a window frame so as to swing open and close freely, and the sash is urged in a window opening direction. The sash is provided on an open side frame of the sash and a frame of the window frame corresponding to the frame. In a swinging opening / closing window which is closed by winding a wire sequentially wound around a pulley onto a drum, a locking body is projected from an outer peripheral surface of the open side frame of the sash (shoji). A corresponding inner peripheral surface of the frame of the window frame,
In the vicinity of the approaching path where the locking body enters when the shoji is closed, a locking member for irreversibly locking the locking body is provided with a locking position protruding into the approaching path and a locking means for retreating from the approaching path. It is freely movable between a release position and a toothed member which is freely movable in a direction perpendicular to the approach path and meshes with an engagement groove formed in the locking member, and the advance and retreat are performed by the advance and retreat. A tension coil spring configured to move a locking member between the locking position and the unlocking position, to connect a feed-out end of the wire to a front end of the toothed member, and to have a first end fixed to the frame at a rear end. The other end of the sash is always moved to bias the toothed member to the retracted position by the elastic force of the tension coil spring, and the tension applied to the wire by further winding the wire after the window of the sash is closed. In the above閉窓 locking device rotationally opened and closed windows, wherein the attached member that has a structure to move to an advanced position against the elastic force of the tension coil spring
