Description

[Detailed description of the invention] [Industrial application field] The present invention is a revolving window in which the window frame and the shoji are connected by an arm to adjust the opening angle of the shoji, especially used on the upper floors of buildings. Regarding revolving windows.

[Conventional technology]

Windows are generally closed on the upper floors of buildings.
Although it is not designed to open, on the lower floors of the building,
A rotating window like that seen in Utility Model Application Publication No. 55-47546 can be seen. This rotating window has a slider provided on one side of the arm so that it can run along a guide groove in the window frame, and a locking plate built into the slider is engaged with wide grooves cut out in various places in the guide groove. The opening angle can be adjusted by pressing an operating pin on the locking plate, allowing the slider to move freely.

Additionally, a mounting bracket or the like is required on the indoor side, making the space less convenient to use.

[Problem that the invention attempts to solve]

In order to be able to open windows freely even on the upper floors of a building, it is possible to use the above-mentioned revolving windows.
However, if it were adopted as is, the conventional revolving window could be opened narrowly or wide with a single operation pin.
If you carelessly open a shoji door wide, you can expect someone to fall out of the window or accidentally drop something, which is extremely dangerous. To eliminate this danger, it is best not to open windows on upper floors. For this purpose, air conditioning equipment is in place, but sometimes it breaks down, and there are also cases where the air conditioning equipment cannot keep up with the unexpected number of people and the indoor air becomes polluted. To solve this problem, conventional revolving windows can be opened and closed only within a narrow range, thereby achieving fall prevention and ventilation at the same time. However, on the other hand, there is also a desire to open the window wide during window cleaning and emergencies, which is incompatible with fall prevention.

Therefore, the purpose of this invention is at least contradictory.
Our objective is to provide a revolving window that satisfies the following needs.

[Means for solving problems]

In order to solve the above problems, the present invention, which will be explained with reference to the reference numbers in the drawings, is a rotating window in which the window frame 2 and the shoji 3 are connected by an arm 6, and the opening angle of the shoji 3 is adjusted. , A second slider 5 is provided on the rotation center side of the shoji 3, and a first slider 4 is provided on the side separated from the shoji 3 so as to be movable along the window frame 2.
The sliders 5 are separably connected in series, one end of the arm 6 is pivotally connected to the second slider 5, and the first
A stopper 7 is provided on the window frame 2 facing the running path of the slider 4, a locking means 16 is provided on the second slider 5 that is biased toward the window frame 2, and a shoji 3 whose angle is larger than the above-mentioned angle is provided.
The window frame 2 is provided with a lock receiving portion 21a on which the locking means 16 is locked, facing the travel path of the second slider 5 at the opening angle position.

[Effect]

Under normal conditions, the second slider is connected to the first slider whose travel range is limited by the stopper, so that the shoji does not open wide by mistake, and fall prevention and ventilation can be achieved at the same time. In addition, when cleaning, the first and second sliders can be uncoupled and only the second slider can be moved further toward the rotation center of the shoji, allowing the shoji to be opened to a wide angle, allowing the front and back sides to be opened. Cleaning becomes easier.

〔Example〕

Examples will be described below with reference to the drawings.

The embodiment is a rotating window A in which a vertical rotating shaft 1 is disposed offset to the right of the center of a window frame 2, and a shoji 3 opens inward, as shown in FIGS. 10 and 11. The lower frame 2a constituting the window frame 2 has a 10th
In the figure, first and second sliders that limit the opening angle of the shoji 3 are arranged at positions indicated by two-dot chain lines. The first and second sliders 4 and 5 are arranged in the longitudinal direction of the lower frame 2a, as shown in FIG.
It is arranged so that it can run toward the center of rotation.
The second slider 5 is arranged before the first slider 4, and both sliders 4 and 5 are separably connected. An arm 6 is pivotally attached to the lower stile of the shoji 3 via a mounting bracket 3a.
The other end is pivotally connected to the second slider 5. These detailed structures are shown in FIGS. 1 to 9, and will be explained in detail below.

First, to explain the lower frame 2a, the lower frame 2a
As shown in FIG. 3, the part in which the first and second sliders 4 and 5 are housed and run is formed in a channel shape, and the slider 4,
In order to stabilize the running of the channel 5 and prevent it from jumping out, two guide lines 2b, 2b extending in the longitudinal direction are provided along the inner wall of the channel. In contrast to the cross-sectional shape of the lower frame 2a, both shoulder portions of the first and second sliders 4, 5 are connected to the guide lines 2b, 2a.
b, both sides are formed to have a substantially convex cross section so as to slide on the inner wall of the channel.

As seen in FIG. 4, the bottom surface of the lower frame 2a, which serves as the travel path for the first and second sliders 4 and 5, has a
Stopper 7 that limits the travel of the first slider 4
is secured with screws. This stopper 7 is the first
It engages with a release button 8 provided on the slider 4, and the stopper 7 is provided with a groove 7a with an open left end and a through hole 7b larger than the groove width at the end thereof. The position of the stopper 7 is related to the opening angle of the shoji 3, and if it is too large, there is a risk of leaning forward, so it is desirable that the stopper 7 be located at a position where the opening angle is about 15 degrees.

The release button 8 provided for the first slider 4 is the first
Its outline is shown in the drawings and FIG. 2, and its detailed structure is shown in FIG. The release button 8 basically adopts a push button type in relation to the stopper 7. This release button 8 is biased upward by a coil spring 9 that comes into contact with the middle flange 8a as a spring seat in the vertical hole 4a of the first slider 4, and the lower small diameter portion 8b further extends into the groove 7a of the stopper 7.
An engagement piece 8c is provided at the lower end of the engagement piece 8c to engage with the through hole 7b. The coil spring 9 is supported by a seat 10 screwed onto the bottom surface of the first slider 4. Furthermore, when the engagement piece 8c engages with the through hole 7b, the release button 8 becomes free to move upwards and may come out, but to prevent this from coming off, the seat 11 that comes into contact with the upper surface of the collar 8a is attached to the first slider 4. It is screwed on the top.

Second slider 5 connected to first slider 4
is separated from the first slider 4 during window cleaning and runs independently on the lower frame 2a to increase the opening angle of the shoji 3. Therefore, shoji 3
The other end of the arm 6, which is pivoted to the lower stile, is pivoted to the second slider 5, as shown in FIG. The pivot shaft 12 has a head 12a and a vertical shaft 1.
2b passes through the vertical hole 5a of the second slider 5 and is caulked via the seat 13. The other end 6a of the arm 6 is pivotally attached to a large diameter portion 12c close to the head 12a, and is prevented from coming off by the head 12a. Further, the arm 6 is positioned by a collar 15 interposed between the arm 6 and a seat 14 screwed onto the upper surface of the second slider 5.

If you simply want to open the shoji 3 wide, please use the second method above.
Although the configuration of slider 5 is sufficient,
The wind is strong on the upper floors of the building, and the 3rd shoji screen can sometimes be blown away by the wind. Therefore, the second slider 5 is provided with an engagement button 16 for fixing the shoji 3, as shown in FIGS. 1 and 2. This engagement button 16 adopts a pool type, as shown in detail in FIG. 7. Engagement button 1
The vertical shaft 17 of the second slider 5 passes through a vertical hole 5b provided in the second slider 5, and the lower portion 17a is a large diameter portion. The upper part of the vertical shaft 17 passes through a through hole 14a of the seat 14, and a pick 18 for pulling up the vertical shaft 17 is caulked to its head. A coil spring 19 is interposed between the large diameter portion 17a and the seat 13 of the vertical shaft 17, so that the large diameter portion 17a protrudes from the upper surface of the lower frame 2a. Furthermore, the small protrusion 20 fitted into the lower end of the large diameter portion 17a is a guide member.

The large diameter portion 1 of the engagement button 16 is located on the bottom of the lower frame 2a.
An engaging member 21 as shown in FIG. 8, which engages with 7a, is screwed. The engaging member 21 is formed with at least one through hole 21a that is larger than the large diameter portion 17a. The through holes 21a may be added at appropriate locations as shown in the figure. In any case, the through hole 21a on the far right is 90
It is desirable to place it in a position where it can be opened up.

Then the connecting means 22 of the first and second sliders 4, 5, shown schematically in FIGS. 1 and 2.
I will explain in detail. Although the structure of the connecting means 22 is shown in FIG. 9, the structure is not necessarily limited to that shown. Both sliders 4,
The first slider 4 is provided with a connecting pin 23, and the second slider 5 is provided with a connecting rod 24, in order to connect the sliders 5 and to make them separable. The connecting pin 23 passes through the vertical hole 4b of the first slider 4 and is inserted together with a coil spring 26 into a cylindrical receiver 25 supported by the upper and lower seats 10 and 11. Head 23 of connecting pin 23
a has a smaller diameter than the body portion 23b, and the small diameter portion 23
a is a cover 2 screwed to the first slider 4;
It is fitted into the through hole 27a of No.7. A gap is provided between the cover 27 and the receiver 25 to allow insertion of the connecting rod 24. A through hole 24a is formed at the tip of the connecting rod 24, which is inserted through the gap, to connect with the body 23b of the connecting pin 23 in a fitted state. The rear end of the connecting rod 24 is screwed to the second slider 5, but if it is too long, the tip will droop and it will be difficult to insert it into the gap.
A guide 24b that is located on the aforementioned guidelines 2b and 2b and slides thereon (see Fig. 1 and Fig. 2).
is screwed near the tip to ensure vertical position.

Since a series of these devices is built in between the window frame 2 and the shoji 3, there are no protrusions around the window frame, resulting in an attractive revolving window.

Next, the operation of the revolving window A will be explained.
In a normal window opening/closing state, the connecting rod 24 of the second slider 5 fits into the connecting pin 23, and both sliders 4 and 5 are connected. This connection is performed by the head 2 of the connecting pin 23 seen through the through hole 27a of the cover 27.
3a is pushed down with a screwdriver, then the second slider 5 is brought close to the first slider 4, and the tip is inserted through the gap between the cover 27 and the receiver 25 so as to pass over the head 23a.

The rotating window A is usually equipped with a lock lever that fixes the shoji 3 to the window frame 2, so when rotating the shoji 3 inward to open it, turn the lock lever to allow the shoji 3 to rotate freely, and then close the shoji 3. Pull the lock lever inward until it stops rotating. This operation causes the shoji 3 to rotate, and at the same time, the first and second sliders 4 and 5 are dragged by the arm 6 and travel toward the center of rotation of the shoji 3. While the first slider 4 is running, the release button 8 of the first slider 4 is pressed down by the stopper 7, but when the engaging piece 8c reaches the through hole 7b of the stopper 7, the engaging piece 8c falls into the through hole 7b and the first slider 4 is pressed down. The slider 4 becomes fixed at that position. Since the arm 6 pivotally connected to the second slider 5 is also fixed, the shoji 3 is fixed at an opening angle of approximately 15 degrees. In the embodiment, since it opens inward, it not only prevents falling, but also effectively prevents unwanted objects from being thrown away.

When closing the shoji 3, push down the release button 8 to disengage the engagement piece 8c from the through hole 7b, and close the shoji 3.
Return to the window frame 2 side.

In addition, when opening the shoji 3 to a wide angle for window cleaning etc., rotate the shoji 3 inward according to the first procedure, and use the gap created between the window frame 2 and the shoji 3 to move the first slider 3. and the second slider 5 are separated. This separation is performed by rotating the shoji 3 toward you while pressing down the head 23a of the connecting pin 23 with a screwdriver-like device. This separation allows the second slider 5 to move freely without being restrained by the first slider 4. From this state, the shoji 3 is further pulled inward and rotated until it stops. With this action, the second
The slider 5 is dragged by the arm 6, and the lower frame 2a
The robot runs toward the center of rotation of the shoji 3. At the end of this traveling process, the large diameter portion 17a of the engagement button 16
is guided by the small protrusion 20 and falls into the through hole 21a of the engaging member 21 screwed to the bottom of the lower frame 2a,
The second slider 5 is restrained by the lower frame 2a. The shoji 3 is fixed at an opening angle of approximately 90 degrees.

When closing the shoji 3 from the above-mentioned fixed position, pull the lock 18 of the engagement button 16 upward and press the engagement member 2.
1 through hole 21a to large diameter portion 17 of engagement button 16
Remove a and rotate the shoji 3 outward. With this operation, the small protrusion 20 rests on the upper surface of the engaging member 21, allowing it to move freely. Furthermore, the shoji 3 is rotated outward, the second slider 5 is returned to the separated position, and then connected to the first slider 4 according to the above-described procedure, and the shoji 3 is further closed.

[Effect of idea]

As explained above, according to the present invention, since the shoji is not opened wide inadvertently, falling can be effectively prevented.

According to a further preferred embodiment, the arm is located on the outside of the shoji and there is no protrusion on the indoor side not only when the shoji is closed but also when it is opened, so the room can be used effectively and the appearance is good.
