Description

[Detailed Description of the Invention] The present invention relates to an improvement in the airtight structure of a double door sash.

In a double-door sash, there is a gap between the upper frame and the upper stile and between the lower frame and the lower stile, and a drainage gasket is installed in the gap to prevent wind and rain from entering from outside. Since this is not sufficient to maintain airtightness, gaskets are attached to the upper and lower frames to maintain airtightness.
In order to maintain the airtightness of the mating part of the sash, one of the sashes is equipped with a gasket that wraps around the other sash. If the length is from the upper stile to the lower stile, there are notches at both the upper and lower ends of the inner side surface, so it is easy to open and close. It can be opened and closed. Therefore, when wind and rain blow from the outside, the outside air such as wind and rain will enter the inside through the gap in the cutout.
There was an imperfection in terms of airtightness. Although some structures have been seen in which the notches at both the upper and lower ends of the sash are sealed, the conventional structure had the disadvantage that airtightness was impaired by the sagging of the shoji due to its own weight.

The purpose of the present invention is to provide an airtight structure for a double door sash having perfect airtightness.

Next, embodiments of the present invention will be described with reference to the drawings. As shown in Fig. 2, the double-opening sash has a gap 3 between the upper frame 1 and the upper stile 2 of the sash, and a gap 6 between the lower frame 4 and the lower stile 5 of the sash. A drainage gasket 7 is provided on the upper frame 1 in the cavity 3 to prevent wind and rain from entering from the outside side a, but in order to improve airtightness, the cavity between the upper frame 1 and the upper stile 2 on the interior side b is provided. The part 8 and the gap 10 between the lower frame 4 and the lower stile 5 are provided with a packing 9 or a packing 9a, respectively. In addition, as shown in FIG.
There is a gap 13 on the outside, a gap 14 on the abutting part, and a gap 15 on the inside between the left side and the other right side stile 12. A gasket 19 is attached to the inner side surface 11a of 11.

However, since the inner side surface 11a of the left side frame 11 is flush with the vertical walls 1a, 4a of the upper frame 1 and lower frame 4 for holding the gaskets 9, 9a, the length of the inner side surface 11a is Since the length from the upper stile 2 to the lower stile 5 corresponds to the vertical walls 1a and 4a, there are notches 16 at both the upper and lower ends of the left side stile as shown in FIG.
are provided, and gaps 17, 18 are created between the vertical walls 1a, 4a, resulting in the above-mentioned drawbacks. In addition, in order to prevent wind and rain from entering through the butt gap 14 when wind and rain blows through the gap 13 on the outside side a, and to maintain the airtight performance of the mating part, the packing is made so that there is a wrap allowance 24 in that area. 19 is provided, and therefore, complete airtight performance is obtained by the packing 19 from the lower end of the gap 17 to the upper end of the gap 18.

In this double door sash, as shown in FIGS. 4 and 7, partial packings 23 are provided at the upper and lower ends of the right binding stile 12 to tightly open the gaps 17 and 18, respectively. 25 is a mounting member that holds the gasket 23. Patsukin 23
are the packings 9 provided on the upper frame 1 and the lower frame 4,
9a so as to maintain airtightness in the vertical direction, wrap the butt part 11b of the left binding frame 11 with the wrapping allowance 22, and attach to the packing 19 provided on the left binding frame 11. On the other hand, a wrap allowance 21 is provided for wrapping. Note that the width of the packing 23 is usually approximately the same as the width of the inner side surface 11a, and as shown in FIG.
9 come into contact with each other, and the space between the left binding stile 11 and the right binding stile 12 is sealed. Therefore, both the upper and lower ends of the joining part are completely airtight.

Therefore, according to the present invention, the upper and lower end parts of the mating part of the sash are sealed by the airtight seals provided in those parts, so that wind and rain can blow from the outside gap. Even if the sash is sealed, wind and rain are prevented from entering through the gaps at both the upper and lower ends of the joining part, and an airtight structure of the sash with perfect airtight performance is obtained.
