Description

[Detailed description of the invention] This invention relates to an opening/closing adjustment device for a revolving window, etc., and particularly relates to an opening/closing adjustment device for a revolving window, etc. that is equipped with a regulating device that regulates the opening angle when the revolving window is opened. It is something.

Conventionally, for example, the opening/closing adjustment device for rotating windows has often been used for windows in hotels, offices, schools, etc., but since anyone can freely open the rotating windows to the maximum extent possible, it has been widely used in hotels, etc. A guest intentionally opens the revolving window and jumps from it;
Furthermore, there was a high risk that a drunk person or a child could accidentally operate the opening/closing control device for the revolving window and fall out of the revolving window.

Therefore, in hotels, etc., when using windows that can be easily operated by an unspecified number of people, taking into account the above-mentioned danger, once the operating handle is removed, a permanent lock is attached so that guests cannot open or close the revolving window. In many cases, this was the case. However, in this case, the revolving window was no different from a closed-in window, and even if one wanted to take in fresh air through the revolving window, it was impossible to do so, which was very inconvenient. Therefore,
It has been desired to propose a device that allows air to be taken in and prevents the above-mentioned dangers, that is, a device that allows the window to open up to a certain extent, but restricts the opening angle beyond that point.

Hitherto, as such a device, the anti-tilting lock described in Japanese Utility Model Application Publication No. 14062/1983 has been generally known. However, in this lock, the body that acts as a stopper is installed in a position where it can easily be seen by people, and since the cylinder lock is built into the body, the body inevitably becomes large, which is not desirable in terms of appearance. Ta. In particular, it is difficult to use in hotels and the like where aesthetic appearance as well as strength and functionality are required.

In addition, when cleaning a rotating window, etc., the stopper must be moved to the end of the arm after unlocking the lock, which is cumbersome to operate.
During operation, there was a risk of injury due to fingers being caught between the support and the body.

Furthermore, when locking the lock after cleaning the rotating window, the slide pin must be inserted through a small hole, which requires time and effort for positioning, and the locking position may be mistaken, making the work extremely time-consuming.

This invention has thus been devised to deal with the various problems mentioned above, and will be explained below based on the embodiments shown in the drawings. In FIG. 1 of the drawings, reference numeral A indicates a rotating window device. In this revolving window device A, the revolving window B has a window frame 2 at approximately the center of its upper and lower frames 1, 1.
It is pivotally supported and can be rotated left and right.

Further, in FIG. 1, reference numeral C indicates a window opening/closing adjustment device equipped with a window opening angle regulating device. The window opening/closing adjustment device C will be explained with reference to FIG.
A support body 5 having a through hole 4 is rotatably attached to the attachment body 3. A rod 6 for adjusting the opening and closing of the rotary window B is loosely fitted into the through hole 4 of the support body 5.

By the way, as shown in FIG. 2, the rod 6 is provided with adjustment holes 7 at a plurality of locations at predetermined intervals along its upper surface in the longitudinal direction. A positioning bolt 8 which is urged to penetrate into the adjustment hole 7 is attached to the support body 5 integrally with a knob 9.

Further, one end of the rod rod 6 is connected to one end of the rotary window B via a mounting piece 10. A stopper 11 is attached to the other end of the rod 6 to prevent the rod 6 from coming out of the through hole 4 of the support 5.

To explain the usage state of the window opening/closing adjustment device C above, lift the knob 9 of the support body 5,
By changing the engagement position between the adjustment hole 7 provided in the rod rod 6 and the positioning bolt 8 of the support body 5, the opening angle of the rotary window B can be freely changed. As shown in Figure 5 of the drawings, it can be opened up to a maximum angle of 90 degrees with respect to the window frame 2.

However, as shown in FIG. 5, being able to open the window up to a 90° angle to the window frame 2 is not desirable from the standpoint of preventing falls. Therefore, in the present invention, the window opening/closing adjustment device C is equipped with a window opening angle regulating device.

Therefore, the fenestration angle regulating device of the present invention will be explained with reference to FIG. A groove 12 is provided on the lower surface of the rod 6 in the longitudinal direction thereof.

Further, the groove 12 may be provided at one location on the lower surface of the rod rod 6, but this location is the adjustment hole 7 for maintaining the fenestration angle θ of the rotary window B, as shown in FIGS. 3 and 4. Adjustment hole 7 when the window is closed
It is preferable to provide it in the section up to. Fine adjustment between the closed state of the rotary window B and the opening angle θ can be achieved by providing adjustment holes at small intervals at corresponding positions on the upper surface of the rod 6.

An engaging piece 14 is provided at a position corresponding to the recessed groove 12, and the engaging piece 14 projects when the cylinder lock 13 provided inside the mounting body 3 is locked. By engaging in the groove 12, the opening angle of the rotary window B can be regulated.

Note that a locking device may be provided inside the support body 5.
In addition, a long groove 12 is provided (for example, a retainer 11
A block-shaped part is fixed at an appropriate position in the concave groove 12 as a stopper for regulating the sliding of the engagement piece, or the stopper part is made to move forward and backward. The length of the groove 12 may be adjusted to an appropriate length by installing an adjusting device.

Then lock the cylinder lock 13 and release the engaging piece 14.
is engaged in the concave groove 12, when the knob 9 of the support body 5 is lifted to adjust the aperture angle of the rotary window B, the aperture angle of the rotary window B corresponding to the end of the concave groove 12 will be adjusted. The positioning bolt 8 can only be engaged up to the adjustment hole 7 that maintains θ. Therefore, in the end, the rotary window B can only be opened up to the opening angle θ shown in FIG. 4 of the drawings.

Thus, this idea consists of the above structure. It goes without saying that the device of the present invention can also be used for casement windows, sliding windows, etc. The rotating window opening/closing adjustment device equipped with the fenestration regulating device according to this invention has the following effects.

As mentioned above, when the cylinder lock is locked, the engaging piece is engaged in the groove, and the rotating window can be opened freely up to a predetermined angle, but cannot be opened beyond that, making it extremely safe. It is ideal for hotels, etc. used by an unspecified number of people.

When cleaning the revolving window, the revolving window can be fully opened immediately after the cylinder lock is unlocked. In addition, to lock the door after cleaning, all you have to do is close the rotating window and lock the cylinder lock, and there is no need for delicate positioning operations like with conventional locks. In other words, the cylinder lock can be locked so that the engaging piece is engaged in the long groove.

In the device according to the present invention, a cylinder lock is installed in the mounting body, and a support body is integrally provided thereon. Furthermore, since the engaging portion between the groove and the engaging piece is not visible from the outside, the exterior is sleek and very stylish.
