In particular, in the case where the door panel that has received the solar radiation is warped so as to expand toward the outside of the room, a phenomenon occurs in which the airtight material does not contact the door panel, and the problem becomes remarkable.

[0004] It is an object of the present invention to provide an airtight material capable of improving airtightness and a fitting using the same.

[0005]

According to a first aspect of the present invention, there is provided an airtight material attached to one of a fitting frame constituting a fitting and a shoji arranged inside the fitting frame, wherein a fin for stabilizing the attachment position is provided. It is an airtight material provided with leg-shaped legs. According to a second aspect of the present invention, there is provided a fitting using the airtight material according to the first aspect, and more specifically, any one of a fitting frame forming the fitting and a shoji arranged inside the fitting frame is provided with a mounting position. It is a fitting to which an airtight material provided with fin-shaped legs for stabilizing is attached. In both of these inventions, since the airtight material has legs for stabilizing the mounting position, even if there is some backlash between the airtight material and the fitting side, the airtight material itself is supported by the legs, A predetermined mounting position is secured. Therefore, a good contact state between the airtight material and the fitting (fitting frame or shoji) is obtained, and the airtightness is improved.

According to a third aspect of the present invention, the airtight material is provided on at least a lower frame of the fitting frame, and further includes a fin-shaped seal portion that comes into contact with the indoor surface of the shoji.
In the lower frame, another airtight material is provided outside the airtight material, and the fin-shaped seal portion that contacts the lower surface of the shoji and the seal portion of the airtight material are different from each other. 3. The two are overlapped with each other when opened.
It is a fitting described in. In such a configuration, since the sealing portion of each airtight material comes into contact with the indoor surface and the lower surface of the shoji, the space between the lower frame of the fitting frame and the shoji is double-sealed, and the airtightness is improved, and a favorable airtightness is obtained. Water tightness is also obtained. In addition, when the seal portions are provided inside and outside the lower frame, rainwater and dust are likely to enter between these seal portions in a state where the shoji is opened. The space formed between the seals is closed, making it difficult for rainwater and dust to enter.

There is no need to worry about cooling of the part, that is, the indoor member and the heat insulating member constituting the frame by the outside air, and the heat insulating performance of the fitting frame is improved. In such an invention, the legs of the airtight material provided between the outdoor member and the shoji do not always need to be used to stabilize the mounting position.
For example, in a fitting frame combining a normal frame and a heat insulating frame, the legs of the airtight material attached to the normal frame are as follows:
Although it functions to stabilize the mounting position, the legs of the airtight material attached to the heat insulating frame may function to stabilize the mounting position, but only function to improve the heat insulating performance described above. It may be something.

According to a fifth aspect of the present invention, the legs of the airtight material attached to any one of the upper frame, the lower frame, and the left and right vertical frames constituting the fitting frame are in contact with the shoji. The fitting according to any one of claims 2 to 4, wherein the fitting is an auxiliary seal portion that is close to the fitting. In such a configuration, since the legs of the airtight material serve as auxiliary sealing portions, the airtightness is further improved by bringing the legs into contact with or close to the shoji.
