When the inner and outer sliding doors 7 and 8 are opened and closed, the closing surfaces 103 of the double upper horizontal airtight members 100 of the upper frames 35 (40) of the inner and outer sliding doors 7 and 8 correspond to each other, as described above. The inner and outer sliding doors 7 and 8 move in contact with the guide vertical walls 12 and 13, and the closing surfaces 84 of the lower lateral airtight members 80 a and 80 b of the inner and outer sliding doors 7 and 8 correspond to the sliding contact surfaces of the corresponding inner and outer sliding doors 7 and 8. 83, and immediately before closing the shoji, the closing surface 94 of the first door-side vertical airtight member 90 facing the outdoor side is in contact with the sliding contact surface 83a on the front end indoor side of the door-side frame 37 (42). Although they move in a contact state, the closing surfaces 103, 84, and 94 are subjected to a sliding treatment to reduce the contact resistance, so that the sliding doors 7, 8 are opened and closed very lightly. When the sliding doors 7 and 8 are opened after the sliding doors are closed for a long period of time, when the airtight material that has not been subjected to the sliding treatment as in the present application is used, the sealing surface of the airtight material is adhered (adhered or fixed) to the partner member to be closed. Although the opening of the shoji becomes very heavy and difficult to perform, the closing surfaces 9 of the left and right first door-end vertical airtight members 90 facing the shoji closing direction are provided.
3. Also on the closing surface 106 of the first combined vertical airtight material 105,
Since the same sliding treatment has been performed, the closing surface 10 described above is used.

The soundproof sash of the present embodiment having the above-described structure has a sound insulation function equivalent to that of the TS-30 class, which has been obtained only when the pulling mechanism is conventionally used, as a result of the measurement according to the JIS standard. The shoji was obtained without being drawn indoors and outdoors.

When the sound insulation is required to be slightly lower than the grade of TS-30, the double sealing structure used in the present embodiment, the second combined vertical airtight material, the second door head, etc. The vertical sealing material may be omitted, and a single sealing structure in surface contact may be used. Conversely, when it is desired to achieve a higher level of sound insulation, the second combined vertical airtight material having fins and the second door-end vertical airtight material are replaced with the first combined vertical airtight material and the first door. As with the vertical sealing material, it is preferable that the sealing material be in surface contact with the sealing surface and the sealing surface be subjected to a sliding treatment. Further, in the present embodiment, the description has been made of the pulling sash, but it is needless to say that the present invention can be applied to a single pulling sash. In this embodiment, since the front ends of the door frames 37 and 42 are pressed against the closing surface 93 of the first door-end vertical airtight material 90, the sealing effect is remarkable. A sufficient sound insulation function can be obtained even with the sealing effect by the surface contact of the 94.

[0027]

As described above, according to the present invention, when the horizontal sliding shoji is closed horizontally, the upper and lower horizontal airtight members face the upper frame and the upper portion of the shoji frame, and the lower frame and the lower portion of the shoji frame lower. In the contact state, the vertical sealing material closes the space between the door frame and the door stop frame in a face contact state, and the sealing material seals the gap between the combining frame and the joining member.
In addition, since the closing members at the top and bottom of the combining section close the top and bottom of the sliding door and the space between the window frames, the inside and outside of the sliding door can be closed without the drawing of the sliding door in the indoor and outdoor directions. In addition, the upper and lower horizontal seals block the upper frame and the upper frame of the shoji, and the lower frame and the lower frame of the shoji in a surface contact state by the blocking surface, and the vertical sealing material at the door between the door frame and the door stop frame. Since it is closed in the contact state, the sealing area of the airtight material is wider than that of the fin-shaped sealing member, and the soundproofing function can be improved. In addition, even if they are in surface contact, the sliding surface is subjected to the sliding treatment, so that the opening and closing of the shoji is extremely easy.

With the double seal structure, the soundproofing function is further improved. Also, the sealing surface of the airtight material provided so as to rub against the partner member to be closed by the opening and closing operation of the shoji,
In the case where the closing portion formed in the foam is provided at the closing portion, the closing portion is easily bent, and the sealing property can be further improved. If the vertical sealing material is provided so that the smoke return of the sliding door of the sliding door is pressed from the opening and closing direction of the sliding door, the opening and closing operation of the sliding door can be pressed directly to the sealing material, so reliable crimping can be performed. it can.
