A main rack 29 is arranged within the lower frame 9 so as to be able to slide laterally. This main rack 29
At the end of the rack 2 there is a rack 2 that engages with the pinion 28.
9a is formed. As a result, the corner fittings 27 for changing direction convert the horizontal movement of the main rack 29 into vertical movement of the connecting plate 25. At this time, the main rack 29 and the interlocking rack 26
The main rack 29 and the interlocking rack 26 are guided by the casing 30 of the corner fitting 27 in order to facilitate their movement. In the figure, 26b is a guide groove for the adjustment stopper screw 24b. Furthermore, the racks 26a and 29a are arranged offset in the direction perpendicular to the plane of the paper so as not to interfere with each other.

The other end of the main rack 29 is shown in FIG.
As shown in FIG. 2, it is fixed via a connecting rod 29b to an actuation section interlocking rack 32 provided on a case body 31 provided at the center of the lower frame 9. Two actuator interlocking racks 32 are provided on the left and right, and are connected at their ends to the left and right main racks 29 having the same structure. In addition, pinions 33 and 33 on the left and right respectively
They are interlocked.

A pair of left and right pinions 33 are engaged with a rack 34 formed at the tip of the operating knob 20. Therefore, by pushing in or pulling out the operation knob 20, the pinions 33, 33 are rotated, and the operating section interlocking racks 32, 32 are moved in the direction away from and the direction toward each other, respectively.
By this movement of the operating unit interlocking rack 32, the vertical frame 7
Slide the opening/closing block 21 inside.

The operation of the above embodiment will be explained below based on FIGS. 13a and 13b.

First, the openings 18a to 18c of the stop plate 19
are set relative to the length of the arm 11 so that the opening angles of the shoji are 15°, 25°, and 45°, respectively. When the operation knob 20 is pushed in, the cam receiving surface 22c of the opening/closing block 21 is aligned with the opening 18c of the stop plate 19, as shown in FIG. 13a, and the operation knob 20 is pushed in.
In the extended state, the cam receiving surface 22a of the opening/closing block 21 is set to coincide with the opening 18a of the stop plate 19, as shown in FIG.

When the shoji is closed, the slider 13 is in position A. In this state, the upper end of the screw 4a hits the lower end of the slider 13, and the operating knob 20
cannot be pulled, and the opening/closing block 21 is always in the state shown in FIG. 13a.

When opening the shoji, the operating knob 20 is pushed in. The opening/closing block 21 is in the state shown in FIG. 13a. When you open the shoji, slider 1 will move through the arm.
3 moves. Since the cam plate 14 is pressed by a push spring 15, its tip is pressed against the stop plate 19. Even when the cam plate 14 reaches the opening 18a, it passes through because this opening is partially blocked by the opening/closing block 21. Further rising, the cam plate 14 enters the cam receiving surface 22b at the opening 18b, but since this groove is shallow, it comes out during upward movement, allowing the slider 13 to rise further.
On the cam receiving surface 22b where the inclined surface of the cam plate 14 and the V-groove shape of the opening/closing block 21 are in the middle, the shoji can be opened continuously, and conversely, when the shoji is closed, the cam plate 14 is engaged with the opening 18b. The shape is said to fit. Top opening 18
At c, the cam receiving surface 22c coincides with the opening 18c and is open. Therefore, the cam plate 14 enters and is stopped within this cam receiving surface 22c. At this time, the shoji is at its maximum open position, which is 45 degrees.

As mentioned above, while opening the shoji, the cam plate 14
When the slider 13 enters the cam receiving surface 22b, the slider 13 can move upward.
Since the cam plate 14 enters the opening 18b when the slider descends, the cam plate 14 can be held in that position. Therefore, the shoji can be opened with the cam plate 14 in the cam receiving surface 22b.

To close the window, pull the operating knob 20. Then, the opening/closing block 21 will be in the state b. That is, since the cam receiving surface 22c is separated from the opening 18c, the cam plate 14 is released from the opening 18c, and the slider 13 can descend. Since the opening 18a is aligned with the cam receiving surface 22a, the cam plate 14
enters the cam receiving surface 22a. Therefore, the shoji always stops at the minimum opening angle (15°). To fully close the shoji, push in the operating knob 20 again.
When the cam receiving surface 22a is displaced from the opening 18a by this pushing, the cam plate 14 can be moved, so that the shoji can be closed.

In the above embodiments, the present invention is applied to a horizontal axis rotating window, but it can also be applied to a vertical axis rotating window. Further, it is a matter of course that the interlocking mechanism from the operation knob 20 to the opening/closing block 21 may be other known means. Furthermore, in the case of small windows, it is sufficient to attach it to only one side of the vertical frame.

Furthermore, since the opening angle of the shoji can be set simply by operating the operating knob, there is no need to operate the arm section as with conventional arm stays. For this reason,
For large windows, etc., it is also possible to install two open holding devices that are operated by one operating knob. This is particularly effective when used in a vertical axis rotating window. In other words, when used for vertical axis rotating windows, arms are required at the top and bottom.
This is because in the case of conventional devices, it is difficult to operate the upper arm portion. In addition, in application to a vertical axis rotating window, by arranging this device as shown in FIG. 14, it is possible to attach two devices, upper and lower, to a large-sized device.

[Effects of the Invention] As described in detail above, according to the window opening holding device according to the present invention, one end of the arm is attached to a slider having a cam plate, and the cam plate is inserted into the opening to open the window in a predetermined position. In addition to setting the angle, the opening can be closed by the opening/closing block that slides by operating the operating knob, and the cam plate can be removed from the opening, so the window can be opened and closed simply by operating the operating knob. become,
Furthermore, the window can be set at a predetermined opening angle. Further, since a plurality of openings are not opened at the same time, if only the desired opening is opened, the opening can be opened to the desired opening position in one go.

Furthermore, in the present invention, when closing the shoji, the opening of the stop plate at the minimum angle is always in an open state, so when closing the shoji, the opening of the stop plate must be stopped once at the minimum opening angle, and then the operation knob must be operated again at that position. Since the shoji cannot be closed, there is no chance of accidents such as hands getting caught when closing the shoji.
