Description

[Detailed description of the invention] This invention is based on the airtight structure of a door, specifically, in a flush door in which a shoji is attached to a rectangular door mounting frame so that it can be opened and closed, the airtightness between the shoji and the door mounting frame when the shoji is closed. It is related to the structure that holds the .

Conventionally, in this type of airtight structure, vertical and horizontal airtight materials were installed on the upper mounting frame, the pair of vertical mounting frames, and the lower mounting frame that make up the door mounting frame, and when the shoji was closed, one side of the periphery of the shoji It is known that the seal is pressed against an airtight material to maintain an airtight state.

However, with this structure, the edges of the vertical airtight material and the horizontal airtight material are joined, which reduces the airtightness of the joint, resulting in problems such as poor airtightness at the corners of the shoji. In addition, when assembling the door mounting frame, the ends of the vertical airtight material and the horizontal airtight material must be joined correctly, which causes trouble, making it difficult to assemble at the installation site. It has the problem that it cannot be knocked down because it has to be assembled and shipped.

This invention was devised in view of the above circumstances, and its purpose is to improve the airtightness of the corners of the shoji and to make it easy to assemble and knock down at the installation site. The purpose is to provide an airtight structure for the door.

Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 is a front view of the flush door, with door mounting frame 1
A shoji 2 is installed inside so that it can be opened and closed.

The door mounting frame 1 includes an upper mounting frame 3, a pair of vertical mounting frames 4, 4,
It has a structure in which a lower mounting frame 5 is assembled into a rectangular frame shape, and the shoji 2 has an upper frame 7, a pair of vertical frames 8, 8, and a lower frame 9 around the panel 6.
In this structure, one vertical frame 8 is attached to one vertical mounting frame 4 via a hinge 20.

The upper mounting frame 3 includes one side wall 3a projecting inward,
One side wall 3a is integrally formed with a substantially U-shaped mounting part 10 that opens toward the other side, and an upper horizontal airtight material 11 is disposed in the mounting part 10 facing oppositely to one side surface 7a of the upper frame 7. It is attached so that it presses against the shoji 2 when it is closed.

The lower mounting frame 5 includes one side wall 5a projecting inward,
A substantially U-shaped mounting portion 12 that opens toward the other side is integrally formed on one side wall 5a, and a lower horizontal airtight material 13 is disposed in the mounting portion 12 facing oppositely to one side surface 9a of the lower frame 9. It is attached so that it presses against the shoji 2 when it is closed.

Each of the mounting vertical frames 4 includes one side wall 4a projecting inward and a rib 14, and the rib 14 is connected to the upper and lower horizontal airtight members 1.
1, 13 lower surface 11 a, upper surface 13 a and its upper surface 1
4b and the lower surface 14C, and the length in the vertical direction is the upper and lower horizontal airtight members 11. Bottom surface 1 of 13
1a, is slightly longer than the distance of the upper surface 13a, and the tip of the rib 14 is bent to form an inwardly directed inclined surface 14a.

Mounting portions 10 of the upper mounting frame 3 are provided at the upper and lower portions of the one side wall 4a,
Cut arrow part 15 so as not to interfere with mounting part 12 of lower mounting frame 5.
．． 16 are each shaped, and each mounting portion 1
Cutouts 17 and 18 are formed in the lower wall 10a and the upper wall 12a of the upper and lower horizontal airtight members 11.0 and 12, respectively.
13 is exposed, and the upper surface 14b and lower surface 14C of the rib 14 are pressed against its lower surface 11a and upper surface 13a.

A vertical airtight material 19 is provided on one side of each vertical frame 8 of the shoji 2, and each vertical airtight material 19 faces the inclined surface 14a of the rib 14 and is pressed into close contact with the shoji 2 when the shoji 2 is closed. At the same time, a cover piece 21 is integrally formed outward on the other side of the vertical frame 8 opposite to the hinge 20, and an auxiliary vertical airtight material 22 is attached to the cover piece 21. It is attached oppositely to the other side surface 4b of one of the mounting vertical frames 4, and is configured to be pressed against and in close contact with the shoji 2 when the shoji 2 is closed.

As described above, when the shoji 2 is closed, one side surface 7a of the upper frame 7 presses against the upper horizontal airtight material 11, and the two side surfaces 9a of the lower frame 9 press against the lower horizontal airtight material 13 and come into close contact with each other. The vertical airtight members 19, 19 can be pressed against the inclined surfaces 14a, 14a of each rib 14, respectively, to maintain an airtight state.

Also, upper and lower horizontal airtight materials 10. 13 is the upper mounting frame 3,
A pair of vertical airtight members 19 are respectively attached to the lower mounting frame 5.
, 19 are attached to the pair of vertical frames 8 and 8 of the shoji 2, so when assembling the vertical airtight material 19 and the upper and lower horizontal airtight materials 11
．． There is no need to join the ends of the parts 13, and it can be easily assembled at the installation site and can be knocked down.

In addition, the upper and lower surfaces 14b and 14C of the rib 14 are pressed against the lower surface 11a and the upper surface 13a of the upper and lower horizontal airtight members 11 and 13, causing the upper and lower horizontal airtight members 11 and 13 to be elastically deformed. 14 and upper/lower horizontal airtight material 11,
Since the airtightness of the joint with the shoji 13 is improved, the airtightness of the corners of the shoji 2 can be maintained better.

Since the present invention is constructed as described above, when the shoji 2 is closed, the upper and lower sides of the shoji 2 are covered with the upper and lower horizontal airtight materials 11,
A pair of vertical airtight members 19, 19 are pressed against and in close contact with 13.
is pressed against the pair of ribs 14, 14 to maintain an airtight state.

In addition, the upper and lower horizontal airtight members 11 and 13 are attached to the door mounting frame 1.
Furthermore, since the pair of vertical airtight members 19, 19 are respectively attached to the shoji 2, there is no need to join the ends of the airtight members, making assembly simple and allowing knockdown.

Further, since the upper surface 14b and the lower surface 14C of the rib 14 are pressed against and in close contact with the upper and lower horizontal airtight members, the airtightness of these parts is improved, and the airtightness of the corners of the shoji 2 is improved.
