Description

The present disclosure relates to fittings.

2. Description of the Related Art Conventionally, fittings including a frame and a shoji arranged in the frame are known (see, for example, Patent Literature 1). A shoji includes a frame body and a face material arranged in the frame body. In the vertical stiles arranged at the ends of the shoji in the left-right direction, anti-vibration members are attached to the upper ends of the vertical stiles of the shoji to suppress vibration of the upper rail of the upper frame of the frame. At the upper end of the vertical frame of the shoji, the upper rail of the upper frame abuts against the anti-vibration member provided at the upper end of the vertical frame to form an airtight line and ensure airtight performance.

The proximal side inclined plate portion 931 extends obliquely downward for a predetermined length while being inclined from the other side in the left-right direction to the one side as it goes downward from above. The bottom side plate portion 932 and the open end side inclined plate portion 933 have the same configurations as the bottom side plate portion 832 and the open end side inclined plate portion 833 of the second embodiment.

In the air leakage prevention member 9 described above, when the outer shoji 3 moves from the open position (see FIG. 11) to the closed position (see FIG. 10), the elastic deformation frame portion 93 is By being pushed by the outer shoji 3, it is crushed upward while having an elastic repulsive force. By further moving the outer shoji 3 to the closed position side, the outer shoji 3 moves from the open end side inclined plate portion 933 of the elastically deformable frame portion 93 to the bottom portion while the elastic deformation frame portion 93 is being crushed. It is moved to the lower surface side of the side plate portion 932 .

In this way, as shown in FIG. 10, the lower surface of the bottom side plate portion 932 of the elastically deformable frame-shaped portion 93 of the air leakage prevention member 9 is provided at the upper end portion of the vertical frame 33 on the door leading side of the outer shoji 3. The upper end of the upper anti-vibration member 52 abuts. As a result, the elastically deformable frame-shaped portion 93 of the air leakage prevention member 9 and the hard upper anti-vibration member 52 come into contact with each other while the elastically deformable frame-shaped portion 93 has an elastic repulsive force, so that the airtight performance can be improved. .

The air leakage prevention member 9 of the third embodiment is elastically deformed by pressing the open end inclined plate portion 933 of the elastically deformable frame portion 93 against the outer shoji 3 in the same manner as the air leakage prevention member 8 of the second embodiment. It is crushed upward while having a repulsive force. Then, the upper anti-vibration member 52 abuts on the upper end portion of the vertical frame 33 of the outer shoji 3 while the elastic deformation frame-shaped portion 93 of the air leakage prevention member 9 has an elastic repulsive force. Therefore, the airtight performance between the upper frame 21 and the vertical frame 33 of the outer shoji 3 can be further improved.

A preferred embodiment of the present disclosure has been described above, but the present disclosure is not limited to the above-described embodiment, and can be modified as appropriate.

For example, in the first embodiment, six fins 72 are provided in the air leakage prevention member 7, but the number of fins 72 is not limited to this. The number of fins 72 may be 2 to 5, or 7 or more. The number of sponge portions (cushion portions) is also not limited.

Further, in the first embodiment, the air leakage prevention member 7 is configured to have the fin portion 72 and the sponge portion 73 (cushion portion), but it is not limited to this. For example, the air leakage prevention member 7 may be composed only of the sponge portion 73 (cushion portion).

1 double sliding window (fitting), 2 frame, 3 outer shoji (shoji), 7 air leakage prevention member, 21 upper frame, 33 vertical frame, 52 upper anti-vibration member (anti-vibration member), 72 fin portion, 73 sponge Part (cushion portion), 833, 933 Open end side inclined plate portion (inclined plate portion)
