Description

[Detailed Description of the Invention] The present invention relates to an airtight structure for maintaining airtightness between the door body and the door attachment frame in a door in which the door body is attached to the door attachment frame so as to be openable and closable.

Conventionally, this type of airtight structure was developed by Utility Model Application No. 52-11355.
As shown in the Yume Publication, there is a known structure in which an airtight material is provided at the part where the door mounting frame and the door body come in contact with each other to maintain airtightness, but in this structure, the airtight material and the door are in contact with each other. Since it is only the airtight material, a strong pressure bonding force cannot be obtained between the two airtight materials, and therefore, the airtight effect is not sufficient.

The present invention was devised in view of the above circumstances, and its purpose is to provide an airtight structure for a door that can maintain airtightness between the door mounting frame and the door body, and that can sufficiently improve the airtightness effect. The goal is to provide the following.

The sealing surfaces 16a, 16a of the vertical airtight members 16.16 are substantially planar, and the outer portions are curved and protrude toward the outdoor side to form curved corner portions 16b, 16b.

Further, an air sealing material mounting groove 17 is formed in the portion of the upper stile 7 that faces the sealing surface 12a of the upper horizontal air sealing material 12, and an upper horizontal air sealing material 18 is mounted in the air sealing material mounting groove 17. , the upper horizontal airtight material 18 consists of a mounting part 18a and a fin-shaped sealing part 18b, and when the door body 5 is closed, the sealing part 18b is attached to the curved corner part 12 of the sealing surface 12a.
The inner side wall 7a of the upper stile chamber, which is in close contact with the airtight member 12 and which forms the airtight member mounting groove 17, is in close contact with the sealing surface 12a of the upper horizontal airtight member 12, so that the sealing surface 12a is slightly depressed and deformed.

Sealing surface 14a of the lower horizontal airtight material 14 in the lower stile 8
An air-tight material mounting groove 19 is formed in the part facing the air-tight material mounting groove 19, and a lower horizontal air-tight material 20 is attached to the air-tight material mounting groove 19. 20b, and the sealing portion 20b is in close contact with the curved corner 14b of the sealing surface 14a when the door body 5 is closed, and an airtight material mounting groove 19 is formed on the inner side wall 8a of the lower frame chamber.
is in close contact with the sealing surface 14a of the lower horizontal airtight member 14, and the sealing surface 14d is slightly depressed and deformed.

- An airtight material mounting groove 21 is provided in the portion of each vertical frame 9, 9 facing the vertical airtight material 16, 16.
．． 21 is formed, and vertical airtight members 22 and 22 are attached to the airtight members mounting R21 and 21, and the vertical airtight members 22 and 2
2 is a mounting part 22a, 22a and a fin-shaped seal part 22b,
22b, and when the door body 5 is closed, the seal part 2
