Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an opening / closing tool for a rotating window.

[Conventional technology and problems]

Generally, as shown in FIG. 6, a rotating window is connected to a window frame 50 via a hinge 51 so that a shoji screen 52 can be freely rotated, and a stopper arm (not shown) fixes the shoji screen 52 in an open position. It has become.

However, according to the above-mentioned mounting method, when the window is closed, the hinge 51 is exposed to the outside, so that the appearance is bad, and by removing the hinge 51 from the outside, the shoji 52 can be separated from the window frame 50. , There was a risk of getting inside the building.

Furthermore, since the hinge 51 and the stopper arm are separate bodies, they must be positioned and attached separately, which causes a problem that the construction is troublesome.

[Problems to be solved by the device]

Then, this invention makes it a subject to provide the opening / closing tool for windows which is excellent in crime prevention and is easy to construct.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention provides a frame plate attached to the inner circumference of a window frame, a shoji plate attached to the outer circumference of a shoji screen, and a linear guide groove formed in the frame plate so as to be movable. A slider provided, a first link whose both ends are rotatably connected to one ends of the plates, one end rotatably connected to the slider, and the other end Is rotatably connected to the shoji plate, one end is rotatably connected to an intermediate part of the first link, and the other end is rotatably connected to the first link and the frame plate. The window opening / closing tool is composed of the third link rotatably connected to the connecting portion.

[Action]

The shoji is attached to the window frame by attaching the frame plate and the shoji plate to the inner circumference of the window frame and the outer circumference of the shoji, respectively.

When the shoji screen is rotated in the closing direction, the shoji plate is rotated and drawn toward the frame plate, and when the window is closed, the plates and links are overlapped between the inner circumference of the window frame and the outer circumference of the shoji screen. It is stored.

When one side of the shoji screen is pushed out to open the window, the slider moves toward the connecting portion between the frame plate and the first link, and each link swings toward the outside. The shoji rotates in the opening direction while being pushed out.

〔Example〕

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

As shown in FIG. 1, a window opening / closing tool 1 according to the present invention is
The frame plate 2 attached to the inner periphery of the window frame F and the shoji W
And a shoji plate 3 attached to the outer periphery of the.

Both ends of the first link 6 are rotatably connected to one ends of the frame plate 2 and the shoji plate 3 via pins 4 and 5, respectively, as shown in FIGS. There is.

A linear guide groove 7 is formed on the frame plate 2 from the other end to the middle portion, and a slider 8 is provided in the guide groove 7 so as to be movable with respect to the pin 4. A pressure plate 9 is provided inside the slider 8, and the tip of a screw 10 screwed into the slider 8 from the surface side is in contact with the pressure plate 9. When the screw 10 is rotated, the pressure plate 9 moves, the bottom wall of the slider 8 is deformed, and the contact pressure between the bottom wall of the slider 8 and the bottom surface of the guide groove 7 can be changed.

One end of a second link 12 is rotatably connected to the slider 8 via a pin 11, and the shoji plate 3 has a second link.
The other end of 12 is rotatably connected via a pin 13.

The intermediate portion of the first link 6 is a third link via a pin 14.
One end of 15 is rotatably connected to this third link.
The other end of 15 is rotatably connected to the frame plate 2 by a pin 4 connecting the first link 6 and the frame plate 2.

On the back side of the shoji plate 3, when the shoji W is fully opened, the second
A stopper 16 is provided that contacts the side edge of the link 12.

According to the window opening / closing tool 1 as described above, the shoji W can be attached to the window frame F only by attaching the frame plate 2 to the inner circumference of the window frame F and the shoji plate 3 to the outer circumference of the shoji W.

When the shoji W is rotated in the closing direction, the shoji plate 3 is drawn to the frame plate 2 while rotating, and when the window is closed, the plates 2, 3 and the links 6, 12, 15 of the window frame F are closed. The inner circumference and the outer circumference of the shoji W are overlapped and stored.

When one side of the shoji screen W is pushed out to open the window, the slider 8 moves in the direction of the pin 4, and the links 6, 12, and 15 swing outward, and the shoji screen plate 3 accordingly. Also, the shoji W rotates in the opening direction while being pushed out.

The shoji W can be opened until the stopper 16 contacts the side edge of the second link 12.

Also, by rotating the screw 10 and adjusting the contact pressure between the bottom surface of the slider 8 and the bottom surface of the guide groove 7, the sliding door W
Can be kept stationary at a constant opening angle.

〔effect〕

As described above, since the window opening / closing tool according to the present invention has the above-described configuration, when the shoji is attached to the window frame, the frame plate and the shoji plate are simply attached to the inner circumference of the window frame and the outer circumference of the shoji, respectively. And can be easily installed.

Further, when the shoji screen is rotated in the closing direction, the shoji plate is rotated and drawn to the frame plate, and when the window is closed, the shoji screen is brought into close contact with the window frame to obtain high airtightness. Since each link is housed in an overlapping manner between the inner circumference of the window frame and the outer circumference of the shoji screen, the appearance is good.

Furthermore, since each plate cannot be removed from the outside, it is excellent in crime prevention.

In addition, if one side of the shoji is pushed out when opening the window, the slider moves toward the end of the window, and the shoji plate and shoji are pushed and rotated by the second link connected to the slider. The end of the shoji on the rotation center side hardly moves toward the center of the window, and the opened shoji does not block the view from the window.
