DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window stay for stopping a rotating shoji provided inside a window frame at an arbitrary open position.

[0002]

2. Description of the Related Art As this kind of stay for opening prevention, a stay described in Japanese Utility Model Publication No. 4-54291 is conventionally known.

[0003] In the above stay for opening prevention, a rail is fixed to a lower frame of a rotating shoji, and one end of an arm is rotatably connected to a slider slidably incorporated in the rail.
The other end of the arm is rotatably connected to the window frame, the slider is provided with a wedge fitting hole having both sides tapered, and a wedge having both sides tapered is incorporated in the wedge fitting hole, By adjusting the height of the wedge, both side walls of the wedge fitting hole are deformed outward and pressed against the inner surface of the rail, and a sliding resistance acting between the slider and the rail allows the rotating shoji to be moved to any open position. To stop and hold.

[0004]

In the above-mentioned stay for opening prevention, an adjusting screw is screw-engaged with a vertically extending screw hole formed in the wedge, and the height of the wedge is adjusted by rotating the adjusting screw. Then, since the slide resistance between the rail and the slider is adjusted, there are the following inconveniences.

That is, the initial slide resistance between the rail and the slider is set by the manufacturer. In that case,
The maker applies a relatively large slide resistance between the rail and the slider to the extent that the rotating shoji in the open state is prevented from closing naturally due to strong wind or the like. Since the slide resistance is a resistance when the rotating shoji is opened and closed, a large operating force is required to open and close the rotating shoji, and the rotating shoji cannot be smoothly rotated.

In order to reduce the operating force, the occupant may rotate the adjusting screw by mistake to reduce the sliding resistance of the slider. However, there was a risk that the opening and closing of the window would be impacted by the influence of the wind, causing damage to the window glass.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the safety of a stay for opening prevention by preventing an initially set slide resistance of a slider from being easily adjusted from the outside.

[0008]

In order to solve the above-mentioned problems, according to the present invention, in a stay for opening a window having the above-described structure, a wedge and a rail are opposed between a wedge and a bottom plate of the rail. screw presses in the direction of looking embedded an elastic member for setting the initial sliding resistance between the slider and the rail cross, vertical through the wedge
A hole is formed and an adjusting screw is screwed into the screw hole .

[0009]

As described above, by setting an initial slide resistance of the slider by incorporating an elastic member between the wedge and the bottom plate of the rail, the stay for opening prevention is attached between the facing portion of the window frame and the rotating sash. In this state, the elastic member cannot be removed, and it is possible to prevent the slide resistance initially set by the manufacturer from being adjusted. Also,
When the adjustment screw is screwed in, the elastic member deforms elastically.
Therefore, the slide resistance can be adjusted.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, the rail 1
A pair of side plates 3 is provided on both sides of the bottom plate 2, and a flange 4 is provided on a side edge of each side plate 3 so as to project inward and outward.

A slider 5 is slidably assembled inside the rail 1, and one end of an arm 6 is rotatably connected to the slider 5 via a pin 7. A connecting member 9 is rotatably connected to the other end of the arm 6 via a pin 8.

The slider 5 has a wedge fitting hole 10, and both sides of the wedge fitting hole 10 are tapered surfaces 11 inclined in opposite directions.

A slide piece 12 is incorporated in the wedge fitting hole 10, and a wedge 14 is housed in a recess 13 formed on the upper surface of the slide piece 12.

Both sides of the wedge 14 are tapered surfaces inclined in opposite directions. A seat plate 1 made of metal is provided between the wedge 14 and the bottom surface of the concave portion 13 of the slide piece 12.
6 and an elastic member 17 made of urethane rubber or the like. By incorporating the elastic member 17, the wedge 14 and the slide piece 12 are pressed in opposite directions, and the slide piece 12 is pressed against the bottom plate 2 of the rail 1. On the other hand, the wedge 14 presses both side walls 10 a of the wedge fitting hole 10 to deform the both side walls 10 a outward, and press the both side walls 10 a against the inner surface of the side plate 3 of the rail 1.

The slide piece 12 is pressed against the bottom plate 2 of the rail 1 and the side walls 1 are pressed against the side plate 3 of the rail 1.
The initial sliding resistance is applied to the slider 5 by the pressure contact of 0a.

The wedge 14 is formed with a screw hole 18 penetrating vertically, into which an adjusting screw 19 is screwed.

FIG. 5 shows an example of the use of the stay for opening having the above-mentioned construction. The rail 1 is fixed to the lower surface of a shoji 21 which is rotatably supported with respect to the window frame 20 by means of screws. Is fixed, and a connector 9 attached to the other end of the arm 6 is screwed to the upper surface of the lower frame of the window frame 20.

In the above-mentioned use condition, the shoji 21
Is rotated, the slider 5 slides in the rail 1.

Here, since the slide resistance is given between the rail 1 and the slider 5 by the incorporation of the elastic member 17, when the sash 21 is stopped at the open position, the gap between the rail 1 and the slider 5 is formed. The sliding door 21 is stopped and held in the open position by the applied slide resistance. In addition,
The opening angle of the sliding door 21 is limited by the contact of the slider 5 with the stopper 22 attached to the end of the rail 1.

If there is a possibility that the open sash 21 may be closed by the influence of the wind, the adjusting screw 19 is turned to pull up the wedge 14 to lift the wedge fitting hole 10.
Are further deformed outward to adjust the pressing force of the rail 1 against the side plate 3, and the slide piece 12 is pushed down to adjust the pressing force of the rail 1 against the bottom plate 2.

When the sliding door 21 is opened and closed, the slider 5 and the slide piece 12 may be seized if they are made of metal.
The slide piece 12 is formed of a synthetic resin, and the rail 1 is formed of a metal such as aluminum.

[0023]

As described above, according to the present invention, an elastic member is incorporated between a wedge incorporated in a wedge fitting hole of a slider and a bottom plate of a rail to reduce initial slide resistance between the slider and the rail. By attaching the stay between the window frame and the sash, the sash can be stopped and held at an arbitrary open position, and the elastic member cannot be removed in a state where the stay for opening is attached. Therefore, there is no inconvenience that the initial slide resistance is erroneously adjusted, and it is possible to prevent the shoji from being opened and closed by shock, and to improve safety.

Further, even if the slide screw changes due to the settling of the elastic member or the like by screwing the adjustment screw into the screw hole of the wedge, the slide resistance is adjusted to an appropriate value by rotating the adjustment screw. be able to.
