DESCRIPTION OF THE PREFERRED EMBODIMENTS A packing according to an embodiment will be described below with reference to the drawings. In the following, the outer surface of the door is
For convenience of explanation, it is used for the near side in FIG. 1, while the inner surface is used for the depth side.

FIG. 1 is a schematic perspective view of a parent and child door to which packing is applied. In this figure, a parent-child door 10 can rotate to the near side with the right side in the figure as a fixed end, a child door 12 that can rotate to the front with the left side in the figure as a fixed end, and a parent door. Door joining portions 13 and 14 located at free edges of the outer surface 11A of the door 11 and the inner surface 12A of the child door 12, respectively, and the door joining portion 1
And packings 16 fixed to the upper and lower openings of the upper and lower lugs.

The door joining portions 13 and 14 are formed in a long strip shape, and are provided so as to slightly protrude from the free edges of the doors 11 and 12, respectively. Thereby, when the parent-child door 10 is in the closed position, the parent door 1
A gap in the direction perpendicular to the door surface generated between the free ends of the first door 1 and the child door 12 can be closed.

As shown in FIG. 2, the packing 16 has a main body piece 18 extending in the longitudinal direction (the thickness direction of the door).
And a thin airtight holding piece 1 erected on the main body piece 18.
9 is provided. The packing 16 is not particularly limited, but is formed of an elastic material such as rubber, and has a shape including a thick portion 22 and a thin portion 23 via a step portion 21 extending along the longitudinal direction. Is provided.
The thick portion 22 is formed by laminating a single member on the thin portion 23 as a base material, but they may be formed integrally. Here, the length in the longitudinal direction of the main body piece 18 is not particularly limited, but is slightly longer than the plate thickness of the child door 12.

The thick portion 22 is formed with two vertically extending slit holes 25 extending in the front-rear direction in the figure. Upper and lower openings 12B, 12 of door 12
C (see FIG. 1). That is, the upper surface side of the thick portion 22 in FIG.
2D (see FIG. 1).

A plurality of the airtight holding pieces 19 are provided upright along the longitudinal direction of the thin portion 23, and can fall down in the longitudinal direction with the upper end thereof being a free end. Here, when the airtight holding piece 19 falls down, a restoring force in the rising direction due to elasticity acts on the airtight holding piece 19.
The height from the base 19A to the upper end 19B of the airtight holding piece 19 is higher than the height of the thick portion 22. Thereby, in a state where the packing 16 is fixed to the child door 12, the surface 19 </ b> C of the airtight holding piece 19 is
Is substantially parallel to the outer surface 12E of the
Are arranged along the thickness direction of the child door 12, and the left end 19 </ b> D of the airtight holding piece 19 faces the side surface 12 </ b> D of the child door 12. It should be noted that a cut is formed between the left end 19D and the thick portion 22 and is provided in a non-contact manner with each other. It has become. Thus, when the airtight holding piece 19 falls down, dust, greetings, and the like accumulated between the airtight holding pieces 19 can be discharged to the outside.

Next, a method of attaching the packing 16 to the child door 12 in this embodiment and the operation of the airtight holding piece 19 when the door is closed will be described with reference to FIG.

First, the thick portion 22 of the packing 16 is fixed to the end faces near the free ends of the upper and lower cutouts 12B and 12C of the child door 12 with screws (not shown). It is arranged to face. In addition, the thick part 22 and the kiguchi 12B, 12C
May be fixed by other means such as bonding. When the parent door 11 is closed from this state, the inner surface 11 of the parent door 11 is closed.
B (see FIG. 1), the upper and lower regions on the free end side contact the surface 19C of the airtight holding piece 19 on the near side, and when the parent door 11 is further closed, the plurality of airtight holding pieces 19 are attached to the inner surface 1 of the child door 12.
It falls down one after another toward 2A side. At this time, the airtight holding piece 1
In 9, a restoring force acts in the upright direction, so that the free end side of the airtight holding piece 19 comes into close contact with the upper and lower cutouts 11 </ b> C and 11 </ b> D of the main door 11.

Therefore, according to this embodiment, when the parent-child door 10 is in the closed position, in addition to the conventional closing of the gap in the direction orthogonal to the door surface by the door joining portion 13, the door joining portion 13 The gap in the direction of the front end can also be closed, and the airtight performance of the parent-child door 10 can be improved.

In the above embodiment, the case where the packing 16 is applied to the parent-child door 10 is illustrated, but the present invention is not limited to this, and may be applied to a one-sided general door.

Further, the airtight holding piece 19 is not limited to a plurality of pieces, and may be constituted by a single piece. However, if there are a plurality of sheets as in the above embodiment, the airtightness of the door can be further improved, and the opening and closing of the parent door 11 can be made smooth.

[0019]

As described above, according to the present invention,
The packing is provided with a main body piece fixed to the front end and an airtight holding piece that is connected to this main body piece and that can fall down when the door is in the closed position, so that a gap in the front end direction of the door joining portion is closed. The airtight performance when the door is in the closed position can be improved.

Further, since the main body piece is provided in a shape having a thick portion and a thin portion via a step portion, and the airtight holding piece is erected on the thin portion, the packing of the present invention can be used, for example, in a parent-child door. In this case, even when there is a slight step in the vertical direction between the free ends of the parent and child doors, it is possible to reliably close the gap in the direction of the front edge of the door joining portion.

Further, since the plurality of the airtight holding pieces are erected substantially parallel to the surface of the door and are arranged along the thickness direction of the door, the unevenness is partially uneven at the opening of the door due to dust or the like. Even if airtightness occurs, the airtight holding piece can fall down in accordance with the unevenness, and the airtightness of the door can be kept substantially constant. Door can be closed,
In addition, damage to the airtight holding piece can be avoided.
