This is to maintain the fully open angle and fully closed position.

FIG. 8 is a sectional view taken along the line CC in FIG. 6, and shows the positional relationship of the arm 11, slider 13, stop plate 119, and cam receiving block 21 that maintain the shoji 10 at a predetermined opening angle.

The cam receiving block 21 is connected by a connecting rod 25 as shown in FIGS. 7 and 9, and the lower part of the connecting rod 25 is fixed to an interlocking rank 26 having a rack 26&.

The interlocking rank 26 is inserted into a corner fitting 27 for changing direction so as to be slidable in the vertical direction, and is engaged with a pinion 28 in the corner fitting 27, as shown in FIG. 1O.

In addition, a main rack 29 that is capable of sliding laterally within the lower frame 9 is inserted into the corner fitting 27, and a rank 29a formed at the end of the main rack 29 engages with the binion 28 so that the main rack 29 can be slid laterally within the lower frame 9. , the binion 28 is rotated as the main rack 29 slides, and the interlocking rank 26 engaged with the binion 28 is caused to slide in the vertical direction. At this time, the main rack 29 and the interlocking rack 26 are moved lj! For smoothness, each main rack 29 and interlocking rank 26 are guided by a casing 30 of a corner fitting 27.

Moreover, 26b is a kite groove of the adjustment stopper screw 24b. Incidentally, the rack 26a and the rack 29a are arranged at positions fl in the direction perpendicular to the plane of the paper so as not to interfere with each other.

On the other hand, as shown in FIGS. 11 and 12, the other end of the main rack 29 is connected to an actuator interlocking rack 32 which is inserted into the case body 31 provided at the center of the lower frame 9 so as to be able to slide laterally. The actuating unit interlocking rack 32 is attached to the case body 31 through a connecting rod 29b, and is engaged with a pair of left and right binions 33, respectively.

An operating rack 34 fixed to the tip of the operating knob 20 is engaged with the above-mentioned pinion 33, and by pressing or pulling the operating knob 20, the operating rack 34 rotates the operating rack 33, The operating unit interlocking rack 32 is moved to the left and right sides of the case body 31, respectively. Incidentally, the racks 32, 32.degree. 34 are arranged at positions shifted perpendicular to the plane of the paper so as not to interfere with each other.

That is, when the operation knob 20 installed approximately at the center of the lower frame 9 is pushed or pulled in the direction of arrow P, the left and right binions 33 engaged with the operation rack 34 at the tip are moved in opposite directions. Rotates at constant speed. As the binion 33 rotates, the actuating unit interlocking rack 32 engaged with the binion 33 moves laterally in the direction of arrow Q, and the binion engaging with the main rack 29 fixed to the actuating unit interlocking rack 32 moves laterally. Rotate 28. Therefore, the direction of the interlocking rank 26 engaged with the pinion 28 is changed by the corner fitting 27, so that the cam receiving block 21 can be slid in the vertical direction.

Next, the operation of the window opening holding device configured as described above will be explained in detail based on FIGS. 13(a) and 13(fb).

First, the openings 18a, 18b and 18 of the stop plate 19
c is set relative to the length of the arm 11 so that the opening angle of the shoji is 15" and 25 to 30 mm and 45 degrees, respectively. In addition, when the operating knob 20 is pushed in, it is shown in FIG. 13(a). As shown, the cam receiving surface 22c of the cam receiving block 21 opens the opening 18C of the stop plate 19, and the cam receiving surface 22c
b opens the opening 18b of the stop plate 19. When the operation knob 20 is pulled, the cam receiving surface 22a of the cam receiving block 21 touches the stop plate 1, as shown in FIG. 13(b).
The opening 18a of 9 is set to be in an open state. When the shoji is closed, the slider 13 is in the position ■. In this state, the upper end of the screw 24a is in contact with the lower end of the slider 13, the operating knob 20 cannot be pulled, and the cam receiver block 21 is always in contact with the lower end of the slider 13 as shown in FIG.
).

Therefore, when the shoji l is opened with the operating knob 20 pressed, the slider 13 moves up within the vertical frame 7, and the stop cam plate 14 is pushed in by the stop plate 19 surface and moves from fx. The stop cam plate 14 has an opening angle of 15°.
The opening 18a slides as it is, and the next opening angle 20~
It stops once at the 30° opening 18b, but since the cam receiving surface 22b of the cam receiving block 21 is shallow, the cam plate 1 is opened by climbing over it and at the opening angle of 45°.
4 protrudes, fits into the opening 18e, and stops.

In addition, when the shoji 1 is opened, the opening 1 has an opening angle of 20 to 30 degrees.
When the stop cam plate 14 is fitted into the cam receiving surface 22b of the cam receiving block 21 at 8b, l;? When the J release operation is stopped, the shoji 1 moves in the opening direction, but does not return to the closing direction.

When the operating knob 20 is pulled at the opening angle position of 4 degrees as shown in FIG. 13(b) Ic, the cam receiver flock 21 rises and the cam receiver surface 22C pushes the stop cam plate 14 to unlock. Therefore, the shoji 1 slides down on the surface of the stop plate 19, and moves in the closing direction to open the opening 18 with an opening angle of 15°.
Stop once at a. In other words, in the state shown in FIG. 13(b) when the operating knob 20 is pulled, the opening 18a and the cam receiving surface 22 of the cam receiving block 21 are aligned, and the stop cam plate 14 protrudes and is inserted into the shoji 1. To fully open the lock, push in the operating knob 20 again and press the stop cam plate 14 at the 1r position to unlock it.

In the above-described embodiment, the present invention was applied to a horizontal axis rotating window, but the present invention can also be applied to a vertical axis rotating window. Further, it goes without saying that the interlocking mechanism from the operation knob 20 to the cam receiving block 21 may be any other known means.

Furthermore, the opening angle of the shoji can be set simply by operating the operating knob, eliminating the need for operating the arm section as in conventional arm-steel systems. For this reason, it is also possible to install two open holding devices that are operated by one operating knob on a large window or the like. This becomes effective in % when used in a vertical axis rotating window. That is, when used in a vertically rotating window, upper and lower arms are required, and in the conventional case, it is difficult to operate the upper arm portion.

When applied to a vertical axis rotating window, by arranging the devices as shown in FIG. 14, two devices, upper and lower, can be installed in a large-sized device.

As explained in detail above, according to the window opening holding device according to the present invention, it is possible to easily set the window to a predetermined opening angle, and it is possible to open the window to the fully open position in one go, or to stop it at an intermediate position. It is safe because it does not close all at once, but once stops at the minimum opening angle, and then completely closes by operating the operating knob.

In particular, when trying to fully open the slider, if the slider passes through the intermediate opening 18b, it will temporarily stop at the intermediate opening angle even if force in the closing direction is suddenly applied due to wind, etc. This has the advantage that there is no danger of In addition, by making the relationship of the cam receiver block to the opening of the stop plate at the minimum opening angle as shown in the example, when attempting to close from the fully open state, it is necessary to stop at the minimum opening angle and push the operating knob. Since it does not close completely, there will be no accidents such as getting your hands caught when it is closed.
