Description

[Detailed description of the invention] This invention relates to an airtight device for soundproof sashes used in buildings, etc., and its purpose is to keep the inner sash open while the outer shoji is fixed. When sliding, the inner shoji can be opened without interfering with the outer shoji, and when the window is closed, the shoji board, the window frame, and the mating frames of the inner and outer shoji are brought into close contact to ensure watertightness and airtightness. The purpose of the present invention is to provide a soundproof sash that has improved effects such as soundproofing and soundproofing properties and completely blocks the outside air from indoors.

In general, schools, residential facilities, etc. that are built in extremely noisy areas such as near airports, railroad tracks, or expressways need to maintain a high degree of airtightness, watertightness, and sound insulation. A so-called soundproof sash is installed on the window frame.

However, in order to prevent the intrusion of water, wind, sound, etc., the airtight device in this kind of conventional soundproof sash has a shoji pulling device pivoted on the side of the stile, and by operating this device, the inside and outside shoji can be moved toward the room. This method eliminates the gap between the shoji and the window frame and maintains an airtight and watertight state, but when opening one shoji, the airtight state of both the inner and outer shoji must be released, and the airtight state of the inner and outer shoji must be released. It was difficult to open and close the shoji because it interfered with other shoji, making the opening operation inconvenient.

Furthermore, when one of the inner and outer shoji doors is opened during a rainstorm, wind and rain can also enter from between the other shoji and the window frame.

Therefore, the present invention improves and eliminates the above-mentioned conventional drawbacks.

The configuration of the present invention will be described below according to an embodiment shown in the drawings.

Fig. 1 shows an outline of the airtight device according to the present invention applied to a sliding sash, etc., where 1,2゜3.4 is a window frame, A is an inner shoji, B is an outer shoji, and 5 is an outer sash. The upper stile of inner shoji A, 6 is the upper stile of outer shoji B, 7 is the lower stile of inner shoji A, 8 is the lower stile of outer shoji B, 9 is the right vertical stile of inner shoji A, and 10 is the upper stile of outer shoji B. The left vertical stile, 11 is a matching stile for inner shoji A, 12 is a matching stile for outer shoji B, and 13 is a tightening bundle.

Next, the specific structure of the airtight device according to the present invention will be explained with reference to FIGS. 2 to 6.

First, in FIGS. 2 and 3, 14 indicates the window frame 1.3.
The protruding guide piece 14 has a two-stage shape and is formed to protrude from above and below, and a contact surface 1 is provided on the upper and lower surfaces of the protruding guide piece 14.
An airtight material 15 for inner shoji and an airtight material 16 for outer shoji, each of which has portions 5a and 16a facing toward the outdoor side, are installed separately.

Reference numeral 17 denotes an airtight connection member for the inner and outer shoji, which is interposed between the airtight material 15 for the inner and outer shoji and the airtight material 16 for the outer shoji in an inclined shape, and the mounting position of the airtight connection member 17 for the inner and outer shoji is the inner and outer shoji. Central stile 11, 12 of shoji A and outer shoji B
15.16 Airtight material for inner and outer shoji at the position where
It is formed in between.

Further, on the upper surface of the window frame 3, guide rails 3a and 3b for the inner shoji A and the outer shoji B are arranged in parallel, and the guide rails 3a.

A hinge type door wheel 18 is rotatably mounted on predetermined positions of the lower frames 7 and 8 of the inner and outer shoji screens A and B on the upper side of the door 3b.

Reference numeral 19 indicates a wind-stopping member attached to the indoor side surface of the matching frame 12 of the outer shoji B, and 20 indicates a matching airtight material, which will be described in detail later.

On the other hand, the outer arms 5a and 7 of the upper stile 5 and lower stile 7 of the inner shoji A
a has its inner peripheral end surface pressed against the contact surface 15a of the inner shoji airtight material 15, and the inner arms 6a, 8a of the upper frames 6 and 8 of the outer shoji B also have their tip portions omitted. It is bent into a letter-shaped shape and protrudes toward the indoor side, and is pressed into contact with the contact surface 16a of the airtight material 16 for the outer shoji.

As described above, the airtight device in the soundproof sash according to the present invention is configured such that the airtight material 16 for the outer shoji shoji is slightly protruded toward the outside of the room than the airtight material 15 for the inner shoji.

This means that when opening the inner shoji A, the tightening bundle 13 pivotally held on the mating frame 11 of the inner and outer shoji A is released, but at this time, the inner shoji A moves toward the outdoor side.
For this reason, as described above, the inner shoji airtight material 16 is provided outside with a dimension slightly larger than its maximum movable dimension.

By doing this, it is possible to avoid interference between the inner and outer shoji frames A and B when the window is opened, and to maintain a complete airtight condition between the inner and outer shoji frames and the entire circumference of the window frame when the window is closed and drawn. It is something to do.

In the case of the structure of the airtight materials 15 and 16 for the inner and outer shoji as described above, there is a problem with the airtightness of the upper and lower parts of the combined frames 11 and 12 of the inner and outer shoji A and H, but the soundproofing material according to the present invention The airtight device in the sash has the airtight structure of the connecting frames 11 and 12 as follows. That is, as shown in FIGS. 4 to 6, the upper and lower ends of the connecting frames 12 of the outer shoji B are The wind stopper member 19 is mounted so as to be movable up and down.

As shown in FIG. 6, this wind blocking member 19 has an inclined surface 19a at its end.

This has the same angle of inclination as the above-mentioned airtight connection member 17 for the inner and outer shoji, and its contact plane 19b is formed to protrude toward the indoor side, so that when the inner and outer shoji A and B are closed, the air A small gap is formed between the contact plane 19b of the stopper member 19 and the matching stile 11 of the inner shoji A.

Further, airtight materials 20 for matching are attached to substantially the entire vertical length of the matching frames 12 of the outer shoji B.

This protrudes toward the indoor side by the same dimension as the contact plane 19b of the wind blocking member 19, and is arranged parallel to the wind blocking member 19.

That is, since the airtight device in the soundproof sash according to the present invention forms the airtight material 15.16 for the inner and outer shojis having a two-stage shape, in the combination frame 11.12 of the inner and outer shojis A and B, the airtight material 15. A gap is created along the entire length of the airtight material 16 in the longitudinal direction by the dimension bone where the airtight material 16 protrudes toward the outside of the room.

However, since the joining part of the sound-insulating sash of the present invention is constructed as described above, it is possible to completely maintain an airtight state in the joining part.

The wind stopper 19 and the airtight material 20 attached to the matching frame 12 of the outer shoji B are connected to the matching frame 11 of the inner shoji A and the airtight material 15 for the inner and outer shoji when the tightening bundle 13 pulls the window closed. .16 and the airtight connection member 17.

As a result, the combination of inner and outer shoji A and B frames 11.
The airtight condition at 12 is from the window frames 1 and 3 to the inner and outer shoji A,
Since the airtight line to B is continuous without being cut, a complete airtight state can be maintained.

Further, since there is a possibility that the contact point between the wind stop member 19 and the frame may be different in the downward direction due to a frame installation error, etc., the wind stop member 19 can be finely adjusted in the vertical direction.

7 and 8 show a second embodiment of the present invention, in which the same parts as in the first embodiment are designated by the same reference numerals.

This example is the airtight material 15.1 for inner and outer shoji of the first example above.
6 and the connecting member 17 for the inner and outer shoji are eliminated, and these are integrally formed.

That is, in the same figure, the airtight material 21 for the inner and outer shoji of this embodiment
is integrally attached to a protruding guide piece 22 that protrudes from the window frame 1°3, and a protrusion 22 a that protrudes from the bottom of the guide piece 22 is fitted at the center position on the indoor side. A matching bulge 21-a is formed.

This is because the airtight material 21 of this embodiment is wide, so that it can be prevented from rising at the central position.

Therefore, by forming the airtight material 21 in this manner, the reliability of the bonding by this connection is improved, and additional parts for setting this, or the labor and effort for fixing this, etc., are omitted.

In summary, this invention separately attaches the airtight material for the inner shoji and the airtight material for the outer shoji to the upper and lower surfaces of a protruding guide piece having stepped portions that protrude from each other along the entire interior circumference of the window frame. An airtight connection member for the inner and outer shojis having an inclined surface is interposed between the airtight materials for the inner and outer shojis, and the outer peripheral end surface of the inner arm of the outer shoji is pressed into contact with the airtight material for the outer shojis. The inner circumferential end surface of the outer arm of the inner shoji is pressed into contact with the airtight material for the inner shoji, and the airtight connection members for the inner and outer shoji are attached to the upper and lower surfaces of the indoor side of the mating stile of the outer shoji. A wind blocking member having an inclined surface with the same angle as the inclination angle is attached so as to be movable up and down, and airtight materials for combination are arranged in parallel so as to be in line contact with the wind blocking member, and when the window is closed and pulled in, this Since the wind-stopping member and the airtight material are pressed against the outdoor side of the matching stile of the inner shoji, when the inner shoji is slid to open the window with the outer shoji fixed, the inner shoji will not move outward. The shoji can be opened without any interference.

In addition, in the central meeting area, the airtight lines from the window frame to the inner and outer shoji screens are continuous without being cut, so a complete airtight state is maintained.

Furthermore, even if there is a difference in the vertical direction of the inside and outside shoji due to a window frame installation error, etc., a reliable airtight state can be maintained because the wind blocking member is formed to be able to be finely adjusted in the vertical direction.
