Description

[Detailed explanation of the invention] In this invention, when the opening is closed, the shoji presses against one side of the inside of the sash to maintain airtightness, but from this closed state it can be easily opened without releasing the pressing operation of the shoji. This relates to windows in buildings that can be adjusted to the desired state.

As is well known, the windows of buildings are housed in sashes that are fixed to the building frame and are movable horizontally or vertically.

A sealing material or a backing material is attached to the inner surface of the sash or the surface of the shoji frame to maintain airtightness in the closed state.

However, over a long period of time, the sealing material and backing material may wear out due to the movement of the shoji, resulting in loss of airtightness.

For example, in high-rise buildings, most of the windows are fitted and the remaining windows can be opened and closed, and the windows that can be opened are opened in the event of a fire or during maintenance inspections, but are kept closed during normal times. be.

Such windows are airtight when closed, but must be constructed so that they can be easily opened.

The present invention relates to a window of a building in which the shoji is always in a closed state with the shoji raised to its highest level, but can be easily opened by pulling down the shoji in an emergency such as a fire outbreak or during maintenance and inspection.

The present invention will be described below with reference to embodiments shown in the drawings.

The sash a in the embodiment of the present invention consists of an upper frame 1, left and right vertical frames 2, 2, and a lower frame 3 each fixed to the frame, and each frame has an open facing surface to receive a shoji screen. .

The upper frame 1 and the left and right vertical frames 2 have a substantially U-shaped cross section with a downward or horizontal cross-section, consisting of a rear part 4 fixed to the frame, an outdoor part 5, and an indoor part 6, with an outdoor part 5 and an indoor part. 6
A backing material 7 along the length direction on the inner surface of either one of the
is attached, and mohair 8 along the length direction is also attached to the other inner surface.

In the embodiment shown in the drawings, a backing material 7 is provided on the inner surface of the interior portion 6.
It has mohair 8 on the inner surface of the outdoor side part 5.

On the other hand, the lower frame 3 is attached to the frame so that the outdoor part 9 and the indoor part 10 face each other, and a backing material 11 along the length direction is attached to the opposing inner surface of the indoor member 10.
A sealing material 12 along the length direction is also attached to the opposing inner surface of.

The interval 13 between the outdoor member 9 and the indoor member 10 is the same width as the opposing interval between the outdoor part 5 and the indoor part 6 of the vertical frame 2, and there is a space below the interval 13 to receive a shoji screen. A portion 14 is formed.

In most cases, this space 14 is surrounded by a wall or the like, but the outdoor side may be left open.

The above-mentioned shoji shoji is made by combining the upper stile 15, the left and right vertical stile 16, 16, and the lower stile 17, and a glass plate 18 is airtightly inserted inside the sash. Attach, wind up one end, and unwind mechanism (not shown)
Suspend it from the other end of a hanging material such as a continuous wire or chino,
It is moved up and down by the operation of the winding and rewinding mechanism.

There are springs 19 at the top and bottom of the side end surfaces of each vertical stile 16 of the shoji screen.
At 19, there is a retainer 20 which can be biased from the left and right to tilt by a certain angle, and the retainer 20 is engaged with a vertical rail 4' provided on the rear surface 4 of the vertical sash frame 2, so that the sash sash can be moved up and down. This is a guide when moving.

The sash a and the shoji sash constructed as described above are provided with a presser 21 that presses the sash against the inner surface of the sash when the sash is in its closed state (in the embodiment shown in the drawings, the shoji is in its highest state).

This presser 21 consists of a roller 22 and a guide 23,
A roller 22 is attached to the upper end of the outdoor surface of each vertical stile 16 and at the middle of the height, and a guide tool 23 is attached to the upper end of the inner surface of the outdoor side portion 5 of each vertical frame 2 and halfway along the height.

Each roller 22 can rotate freely, and each guide tool 23 has an inclined surface 23' on which the roller 22 slides and presses against the inner surface of the indoor portion 6 when the shoji screen is in its highest position.

Therefore, in the closed state where the shoji screen is at its highest position, each roller 2
2 slides onto the inclined surface 23' of the guide 23, the shoji screen moves toward the indoor side, and various indoor surfaces are brought into contact with the backing materials 7 and 1.
1, it is possible to airtightly shield the outdoor side and the indoor side.

On the other hand, when the shoji screen is lowered to open the opening, the roller 22 comes off the guide tool 23.

Therefore, the pressure on the backing materials 7 and 11 is released, and the shoji shoji slides down by its own weight and falls into the space 14, allowing the sash to be opened.

When the shoji shoji is raised again from this open state, each roller 22 slides onto the slope 23' of the guide tool 23 just before it rises to its highest point, and in the highest state, the shoji shoji is pressed against the sash and is airtightly shielded. become.

The rollers 22 and guides 23 described above may be provided on two sides of the sash and the shoji.

For example, rollers 22 and guides 23 may be provided on the upper and lower frames of the sash and the upper and lower frames of the shoji, or rollers and guides may be provided on the left and right vertical frames of the sash and the left and right vertical frames of the shoji. ,
When the shoji is closed, it is pressed against the sash to form an airtight shield.

However, if rollers and guides are provided on three or four sides of the sash and shoji, the shoji can be pressed securely and the airtightness can be further improved.

If the rollers and guides are provided on the indoor side of the sash and shoji, the shoji will be pressed against the indoor side of the sash in the closed state, thereby airtightly shielding the sash.

Further, rollers may be provided on the sash and guide tools may be provided on the shoji.

In summary, according to the present invention, when the shoji is closed,
A roller and a guide tool for pressing the sash against one of the inner surfaces of the sash are provided on the sash and the shoji, respectively, to improve airtightness in the closed state.

The pusher, which consists of a roller and a guide, is almost invisible from both the outside and the inside, so it does not detract from the aesthetics, and it is especially useful in high-rise buildings to harmonize with other glazed windows. can.

Since the pusher consists of a roller and a guide, there is almost no frictional resistance when opening and closing the shoji, and the shoji can be moved up and down extremely easily.

In addition, since the shoji is pressed against the sash when closed, it does not move slightly due to wind and rain and generates noise, and no special operations or unnecessary force are required when opening and closing the shoji.

In addition, the shoji is supported by retainers that are installed above and below the side end faces of the vertical stile and can be tilted by a certain angle under the force of a spring, fitting into vertical rails installed at the rear of the vertical frame of the sash. When the shoji is moved up and down, it does not swing and the stile does not come into contact with the sash.

Therefore, it can be used in various ways as an emergency evacuation window for high-rise buildings, or as a window for smoke exhaust or natural ventilation in the event of a fire.
