Description

[Detailed Description of the Invention] Industrial Application Field of the Invention The present invention is to mount a shoji on a window frame so that the shoji can be freely opened and closed to bias the shoji to open the window. The present invention relates to a device for locking a shoji screen in a closed window state in a swinging open / close window in which a wire wound around a pulley provided in the frame is wound around a drum to close the window.

2. Description of the Related Art Conventionally, as a window locking device for a swing opening / closing window of this kind, one pair of pinching bodies having a wedge-shaped biting portion facing each other and protruding from a window frame is fixed to one side and the other to the other side. It is mounted so that it can swing freely and is urged in the clamping direction, and the shoji has a fitting plate that fits between the two clamping bodies.When the window is closed, the fitting plate fits between both clamping bodies. Then, the fitting plate is locked between the narrowing plates as if the biting part bites into it and is prevented from coming off, so that the fitting plate is locked in the closed window state. It is known that the lock is released by pulling the lock releasing wire to separate the movable side pressing member from the fitting plate.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the conventional device as described above, the mounting position of the fitting plate is finely adjusted so that there is no gap between the fitting plate and the fixed side pressing plate when the window is closed. Not only is it time-consuming to install, but as the number of times of use increases, the biting part of the pressure plate and the pinched surface of the insert plate wear out, and the insert plate does not compress at both narrows. There is a risk that the lock function may not be achieved by slipping out from between the boards, and in addition to the operation to remove the latch of the winding drum so that the wire for opening and closing the shoji can be fed out when the window is opened, the wire for unlocking the shoji Since the pulling operation is required, the window opening operation is troublesome.

Means for Solving the Problems As means for solving the above problems, a rocking window locking device of a swing opening / closing window according to the present invention is a swinging door which is mounted on a window frame so that the sliding door can be freely opened and closed. Each side of the frame of the window frame corresponding to the open side frame of the shoji and the frame that is urged in the direction is provided with pulleys on the surfaces facing each other when the window of the shoji is closed, and the wire sequentially hung on the pulley is attached to the drum. In the swinging open / close window that is configured to close the window by winding, one of the pulleys on the window frame side and the shoji side is fixed in a fixed position, and a locking body is provided on the side of the pulley to project. The other pulley is attached to a sliding body that is mounted so that it can move freely along a guide in a direction perpendicular to the opening / closing direction of the shoji, and the sliding body is locked to a locking body to swing the shoji in the window opening direction. Lock member to prevent the lock member from being locked by the spring elastic force. In addition to urging the movable unlocking position to move, the pulley on the movable side receives the component force in the direction opposite to the urging direction of the spring force of the tensile force acting on the wire as the wire is wound. The sliding member is moved to a locking position where the locking member can be locked to the locking member against the spring elasticity, and the locking member is brought into contact with the locking member when the shoji door is closed to unlock the locking member. The configuration is such that an inclined surface is provided to allow the relative advance while allowing it to escape to the position side.

Action and effect of the invention In the fenestration state where the wire is unwound, the tension force does not act on the wire, so that the sliding body with the movable pulley attached causes the locking member to lock to the locking body due to the spring elasticity. It has moved to an impossible lock release position. When the wire is wound around the drum from this open window state, the shovel on the shoji side is pulled toward the window frame side by the pulling force of the wire and gradually closes the window.At that time, the sheave on the movable side pulls on the wire. In response to the component of the force in the direction opposite to the direction of the moving force due to the spring elasticity, the sliding body with the pulley is guided to the locking position where the locking member can be locked to the locking body against the spring elasticity. Move along. When a shoji comes just before the window closes,
The inclined surface of the lock member hits the locking body, the lock member and the sliding body escape to the lock release position side against the component force of the tensile force of the wire, the lock member advances, and the shoji completely closes. By the way, when the locking body is disengaged from the inclined surface, the locking member again moves to the locking position by the component force of the tensile force of the wire and locks on the locking body, and the latch member or the like causes the locking member to move in the feeding direction of the drum. When the rotation of the wire is blocked and the pulling force of the wire is maintained, the locking of the locking body by the locking member is maintained and the shoji is locked in the closed window state.

When the window is opened, if rotation of the drum in the extension direction is allowed,
By removing the tensile force applied to the wire,
The sliding body moves to the lock release position by the spring elasticity, the lock is released by the lock member being disengaged from the locking body, and the shoji is opened while the wire is paid out from the drum by the urging force of the window opening. .

As described above, according to the present invention, the opening side frame of the shoji screen and the locking body projecting from one of the facing surfaces when the window frame corresponding to the shoji screen is closed are provided with the opening and closing direction of the shoji screen depending on the presence or absence of the pulling force of the wire. That is, since the structure is such that the locking member on the opposite side moves forward and backward in the direction perpendicular to the relative approach direction of the locking body, the locking should be performed even if there is some error in the mounting position of each component. It is possible to eliminate the need for highly accurate adjustment of the mounting position and simplify the mounting work, and there is no risk of slipping off due to the wear of the engaging portion as in the conventional device, The locking function of shoji can be surely achieved over 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.

As shown in FIG. 4, the sliding body 21 abuts on the stopper shown in FIG. 4 and is held at a lock releasing position where the locking pawl 35 cannot lock the locking roller 16. On the other hand, when the wire 6 is wound and the tensile force F in the direction of the arrow in the figure is applied to the wire 6, the inward component force of the tensile force F along the guide rail 18 is moved to the movable pulley 8 The sliding body 21 moves inward against the resilience of the tension coil spring 40, hits a stopper (not shown), and the locking claw 35 can be locked by the locking roller 16. It is located in.

 Next, the operation of this embodiment will be described.

In the fenestration state in which the wire 6 shown in FIG.
Since the tensile force does not act on the wire 6, the shoji 3
The sliding body 21 provided at the position is stretched in the direction of arrow A by the elastic force of the tension coil spring 40 and is positioned at the lock release position. When the wire 6 is wound around the drum from this fenestration state,
The pulling force F shown by the arrow in the figure acts on the wire 6, and the pulley 8 on the shoji 3 side is pulled toward the window frame 2 side to gradually close the window. At that time, the pulley 8 on the side of the shoji 3 receives the component force of the tensile force F of the wire 6, and the slide body 21 to which the pulley 8 is attached is attached.
However, against the elastic force of the tension coil spring 40, the lock claw 35 moves along the guide rail 18 to the lock position corresponding to the locking roller 16 as shown by the arrow B.

When the shoji 3 comes just before the window is closed, as shown in the fifth, the inclined surface 36 of the lock claw 35 moving to the lock position hits the locking roller 16 so that the lock claw 35 and the sliding body 21 move. The locking claw 35 advances while escaping to the lock release position side as shown by the arrow A against the component force of the tensile force F of the wire 6, and when the shoji 3 is completely closed, the locking roller 16 is inclined. 6, the lock claw 35 moves again in the direction of arrow B by the component force of the tensile force F of the wire 6 and the lock claw 35 is locked to the locking roller 16 as shown in FIG. Then, when the rotation of the drum in the feeding direction is blocked by the latch member and the pulling force of the wire 6 is maintained, the locking of the locking roller 16 by the locking claw 35 is maintained and the shoji 3 locks in the window. To be done.

When the drum is unlatched and allowed to rotate in the feeding direction at the time of opening the window, the tensile force applied to the wire 6 is removed, so that the sliding body 21 is moved by the restoring elastic force of the tensile coil spring 40. As shown by arrow A in FIG. 7, the lock 6 is moved to the lock release position, the lock claw 35 is disengaged from the locking roller 16, and the lock is released, and the wire 6 is drumed by the opening force of the gas stay 5. The shoji screen 3 is opened while being drawn out from.

As described above, in this embodiment, the locking roller 16 projecting from the upper frame 2a of the window frame 2 moves forward and backward in a direction perpendicular to the relative approach direction of the locking roller 16 depending on the presence or absence of the pulling force of the wire 6. Since the lock claw 35 on the shoji screen 3 side is used for locking, for example, the locking roller 16 is mounted at the lock position.
Even if it is slightly deviated within a range corresponding to the inclined surface 36, the locking can be performed, and highly accurate adjustment of the mounting position can be eliminated, and the mounting work can be simplified. Further, there is no place to be worn due to the rocking operation, and there is no possibility of slipping off due to the wear. Further, if the latch of the drum is removed, the lock of the shoji screen 3 is automatically released, so that the window opening operation can be performed with one tap.

In addition, the locking roller 16 of the present embodiment is the locking body of the present invention,
The guide rail 18 of this embodiment corresponds to the guide of the present invention, and the lock claw 35 of this embodiment corresponds to the lock member of the present invention.

On the contrary to the above embodiment, the fixed pulley 7 and the locking roller 16 may be attached to the shoji 3 side, and the movable pulley 8 and the lock claw 35 may be attached to the window frame 2 side.

Further, the present invention is not limited to the inclining window shown in the above-described embodiment, but may be any other type of window such as an outward window or a projecting window. The window was energized, and the wires attached to the open side frame of the shoji screen and the frame of the window frame corresponding to the frame were sequentially wound around the pulley to close the window. The same can be applied to all swing opening / closing windows.
