Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention provides a rotating mechanism in which a catch is directly attached to the surface of a glass plate, and a support fitting is attached to the catch to support the glass plate so that it can be opened and closed. It's about windows.

<Prior Art> In a building in which a smoke exhaust membrane cell 11 is installed, a smoke exhaust window must be installed to exhaust smoke generated in the event of a fire.

Conventional smoke exhaust windows are made up of left and right vertical stiles, an upper stile, and a lower stile, and a shoji with a glass plate fitted in it is rotatably pivoted, and this shoji is supported by a buffer mechanism such as an oil damper or a spring. However, in the event of a fire, the latch mechanism was released and the shoji was opened by tilting it toward the indoor side or the outdoor side using the buffer mechanism.

Further, rotating windows for ventilation in general buildings, high-rise buildings, etc. have almost the same structure as the above-mentioned smoke exhaust windows.

<Problems to be Solved by the Invention> However, in the above-mentioned conventional revolving windows for smoke exhaust or ventilation, the buffer mechanism appears on the surface of the shoji, making it unsightly and detracting from the beauty of the building. In the event of an emergency, the buffer mechanism may become inoperable and the shoji may not open.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and includes mounting seats on the left and right sides of the surface of a glass plate, attaching vertical support fittings to the seats, and installing a frame body. Pivotly attach the above-mentioned letter holding bracket to the bracket fixed to the
The support metal fittings and the receiver are housed in a vertical cover provided on a vertical frame, and the glass plate is positioned on the opening side from the pivot point of the support metal fitting and the receiver, and is biased in the opening direction by its own weight. Not only does it have an extremely good appearance, but it also allows the glass plate to be reliably opened under its own weight by releasing the latch mechanism.

<Example> The present invention will be described below with reference to the embodiments shown in the drawings.The rotating window l of the present invention includes a frame body 2 which supports a glass plate 3 which is not provided with a frame vertically or horizontally so as to be tiltable. The frame body 2 is formed by assembling an upper horizontal frame 4, a lower horizontal frame 5, and left and right vertical frames 6, 6, and is generally a silent or mullion frame. An upper cover 7, a lower cover 8, and a vertical cover 9 are attached to the inner surfaces of the upper horizontal frame 4, the lower horizontal frame 5, and each vertical frame 6, respectively.

On the other hand, seats 10 are attached to the top and bottom of the left and right sides of the surface of the glass plate 3 described above. This seat 10 may be directly attached to the surface of the glass plate 3 by 161 m, for example, using ceramic solder, or may be inserted into a hole made in the glass plate 3 and fixed with a screw or the like. Support fittings 11 provided on the left and right sides of the plate 3 are fixed to upper and lower seats 10 and positioned within each vertical frame 6.

This support fitting 11 has a long U-shaped cross section in the vertical direction, has a guide rod 12 extending in the length direction, and the upper and lower ends of the guide rod 12 are fixed to fixed seats 13 provided above and below the support fitting 11. At the same time, the coil spring 14 is attached to the guide rod 12.

On the other hand, the lower ends of the above-mentioned supporting metal fittings 11 are pivotally connected to the receiving fittings 15 fixed to the inner surfaces of the left and right vertical frames 6 by shafts 16. Above axis 1
6 is passed through the lower end of the support fitting 11, and the end of the shaft 16 is inserted through the arcuate hole 17 formed on the left and right sides of the support fitting 15, so that the support fitting 11 can rotate around the shaft 16 as a fulcrum. It is.

Therefore, by fixing screws passed through the upper and lower fixing seats 13 from the surface to each catch seat 10 to fix the support metal All to the glass plate 3, and by fixing the receiver 15 to the vertical frame 6, the glass plate 3
can be tilted about the shaft 16, and since the glass plate 3 is located on the tilting side of the shaft 16, the glass plate 3
is urged to open by its own weight.

A slider 18 is slidably provided on the support fitting 11 and the guide rod 12, a connecting rod 19 is connected to the slider 18 and the aforementioned receiver 15, and the aforementioned coil spring 14 is attached to the lower fixed seat. Wear it between 13th and slider 1st. Therefore, if the glass plate 3 is in an upright state and is in a closed state, the support metal fittings 11
and the connecting rod 19 are substantially parallel, the slider 18 is located near the upper fixed seat 13, and the coil spring 14 is in an expanded state. However, the glass plate 3 is
When the slider 18 is tilted toward the open side using the pivot point 6 as a fulcrum, the slider 18 is guided by the support metal fitting 11 and the guide rod 12 and slides toward the fixed seat 13 below, and the coil spring 14 gradually contracts. When the glass plate 3 is in the open state, the coil spring 14 is sufficiently contracted as shown by the chain line in FIG. 5, so the slider 18 stops, and the connecting rod 19 supports the glass plate 3 in the open state. Therefore, the glass plate 3 is opened by supporting the shaft 16 and tilting it to # and I until the coil spring 14 sufficiently contracts and the slider 18 stops sliding. Also, when the glass plate 3 is manually tilted upright, the slider 18 slides toward the fixed seat 13 above, so the window can be closed using the tension of the coil spring 14. Since the tension of the spring 14 is weaker than the weight of the glass plate 3, the glass plate 3 is not automatically tilted in the closing direction by the coil spring 14.

The upper end of the glass plate 3 described above is always locked by a latch mechanism 20 provided on the vertical frame 6. This latch a mechanism 20
consists of a lock mechanism 21 provided within the upper cover 7 and an engagement mechanism 22 provided on the upper surface of the glass plate 3.

The locking mechanism 21 is a horizontal board 23 fixed within the upper cover 7.
A movable locking plate 24 is provided, and a hook-shaped locking piece 25 is formed in the middle of the locking plate 24. On the other hand, the engagement mechanism 22 has a hook-shaped engagement piece 27 tiltably provided on the surface of a plywood 26 that is fixed to a seat directly attached to the surface of the glass plate 3, and the engagement piece 27 is formed by a spring or the like. (not shown) is always urged to be locked to the locking piece 25.

Note that the locking plate 24 has a wire (
(not shown), and the other end of the wire is connected, for example, to an operating lever provided on the indoor side of the vertical member. When the operating lever is operated, the wire moves and the locking plate 24 is moved. slides, so the locking piece 25 locks the engaging piece 2.
7 can be unlocked.

Since the present invention has the structure a described above, when the glass plate 3 is in an upright state and is in the closed state, the locking piece 2 of the latch mechanism 20
5 is engaged with the engagement piece 27 and supports the glass plate 3.

In this state, as described above, the coil springs 14 of the left and right supports All expand, and the supports All and the connecting rods 19
are housed in the vertical cover 9 in a parallel manner. Therefore, since each support fitting 11 is not visible from the indoor side,
It does not spoil the appearance of the room.

On the other hand, when the wire is moved and the locking plate 24 is slid by operating the operating lever, the locking piece 25 comes off from the engagement piece 27, so the glass plate 3 is unlocked and the glass plate 3 can be tilted freely. The situation becomes yE.

Since the glass plate 3 is located on the tilting side of the shaft 16 as described above, it is tilted toward the opening side at zero, and is gradually opened while being buffered by the coil spring 14 with the shaft 16 as a fulcrum.

When the glass plate 3 is tilted sufficiently, the slider 18 contracts the coil spring 14 and stops, and the glass plate 3 becomes fully open. - When the glass plate 3 is manually tilted to stand upright, it gradually closes, and when the engaging piece 27 locks with the locking piece 25 when the glass plate 3 is in the upright position, the glass plate 3 is fixed and maintains the closed state. Become.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and can be implemented in any manner as long as the structure described in the claims is not changed. For example, the glass plate 3 may be tilted toward either the outdoor side or the indoor side, and the latch mechanism 2° may have any structure.

<Effects of the Invention> In summary, according to the present invention, seats are attached to the left and right sides of the surface of the glass plate, vertical support fittings are attached to the seats, and the support fittings are attached to the fittings fixed to the frame. The above-mentioned support fittings and receivers are stored in a vertical cover provided on a vertical frame, and the glass plate is positioned on the opening side from the pivot point between the support fittings and the receivers, and is attached by its own weight in the opening direction. Since the supporting metal fittings are not visible from the inside or outside of the room, it looks good and does not spoil the aesthetics of the room.
Since the glass plate tilts to open due to its own weight simply by unlocking the latch a mechanism, it does not become inoperable in an emergency, and is of high practical value.
