DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window opening / closing apparatus for opening / closing a window by manual or automatic driving means and allowing a shoji to freely move within a certain range by wind force or the like.

[0002]

2. Description of the Related Art A window provided with manual or automatic driving means and opened and closed by remote control has a sliding door and driving means connected by a transmission mechanism. For this reason, it is difficult to move the sash (shoji) stopped at an arbitrary position freely (irrespective of the driving means). To move this shoji freely,
It is necessary to provide a one-way joint which transmits to the transmission mechanism or the like only from the driving means in the shoji direction and is free in the reverse direction.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a window opening / closing apparatus which can freely displace a shoji stopped at a desired position by a driving means within a predetermined range.

[0004]

According to the present invention, there is provided a window opening / closing device comprising a shoji, a driving means for the shoji, and a transmission mechanism for connecting the shoji and the driving means, wherein the transmission mechanism comprises: An idle swing mechanism including a driving body that reciprocates by driving means and a driven body that engages the driving body with a predetermined play, wherein the driving means reciprocates the driving body and It is characterized in that the body is pushed to urge the shoji in the direction of the fenestration or in the direction of the fenestration, and that the shoji is freely displaceable by the play at any position.
In another aspect of the present invention, a slider of a lock mechanism that locks and unlocks the sash is provided in the housing of the idle swing mechanism as the driving body moves in the window opening direction and the window closing direction. It is characterized by being.

[0005]

According to the present invention, the swinging mechanism allows the shoji to be freely displaced within a certain range at a desired degree of opening of the shoji without the need to operate the driving means. For this reason,
It is suitable for windows whose opening is automatically adjusted by wind pressure or the like, like a shoji that opens under negative pressure.

In the window opening / closing device according to the second aspect, the transmission mechanism includes: a screw that is rotated by the driving means; a driving body that is screwed to the screw and reciprocates with the rotation of the screw; A swinging mechanism having a driven body that holds and engages with the play, rotates the screw by the driving means, reciprocates the driving body, pushes the driven body, and pushes the sliding door in the window opening direction or the window closing direction. It is characterized in that the shoji can be displaced by an amount of play at any position while being moved. With this configuration, the size of the idling mechanism can be reduced. Further, a slider of a lock mechanism for automatically locking and unlocking the shoji is provided in the housing of the idling mechanism. For this reason,
The slider of the lock mechanism, which protrudes outward and is bulky, is accommodated in the idle swing mechanism, so that it is not necessary to provide the slider at the lower part, upper part, or side part of the window frame, thereby improving the workability and appearance.

In this case, the power supply time to the motor of the transmission mechanism is set to be slightly longer, and after the window of the shoji 6 is closed, the actuator 103 of the driving body 45 is moved to the slider 101.
Of the slider 101.
Along the vertical slit 104 from the position indicated by the solid line in FIG. Then, the lower latch 107 and the upper latch 110 slide in the direction shown by the arrow in FIG. 8 against the urging force of the extension spring 111 via the wire rope 106. Thus, the protrusion 1 formed on the lower latch 107
07a is a hook portion 11 attached to a lower cross portion of a shoji 6
2, the protrusion 110 a formed on the upper latch 110 is hooked on the hook 113 attached to the lower rail of the shoji 6, and the window of the shoji 6 is locked. Also,
In unlocking the window of the shoji 6, the slider 101 of the driver 46 is moved by moving the driver 46 downward.
Is released. For this reason, the extension spring 111
The slider 101 moves from the position indicated by the broken line in FIG. 6 to the position indicated by the original solid line in FIG. As a result, the lower latch 107 and the upper latch 110 move in the direction opposite to the arrow in FIG.
The hooks a and 110a are released, and the sliding door 6 is unlocked and the window can be freely opened.

As described above, the slider 101 of the lock mechanism 100 for automatically locking and unlocking the shoji 6 is provided in the housing 42 of the idle swing mechanism 4. For this reason, the slider 101 of the lock mechanism 100 which protrudes outward and is bulky fits in the idle swing mechanism 4, and the lower part of the window frame,

This lock mechanism 100 is different from the fourth embodiment in that
A rectangular bar member 114 is provided along the window frame.
14 is provided with a plurality of protrusions 114a on the inner peripheral surface. The crosspiece 114 is linked to the horizontal piece 101b of the slider 101 by a pin via a lever 115 and a bracket 54 to form a multipoint lock mechanism. As a result, the slider 101 moves with the opening and closing of the window of the shoji 6, the lever 115 rotates in the direction of arrow R in FIG.
As shown by, it is possible to reciprocate up and down. By doing so, the lock mechanism 100 can be entirely concealed, and the appearance is further improved, as well as the workability, and the design is excellent. In a specific implementation, the lock mechanism 100 according to the fourth embodiment of the present invention may be incorporated in the idle swing mechanism 4 in FIG.
