Description

[Detailed Description of the Invention] This invention relates to an airtight structure for a shoji screen, and its purpose is to provide an airtight structure for a shoji screen that can maintain airtightness over a long period of time.

Conventionally, the structure of maintaining the airtightness of the shoji frame by bringing the stile of the shoji frame into contact with the airtight material attached to the sash frame was as follows: ■Protrusions were provided on the stile and the airtight material attached to the sash frame was brought into contact with the ridges. There are two methods: (1) attaching an airtight material to the stile and bringing this airtight material into contact with the airtight material attached to the sash frame.

In method ①, if you pull the shoji to the airtight material of the sash and press the edge of the protrusion and the airtight material to make contact, the protrusions will dig into the airtight material, causing damage to the airtight material over a long period of use, resulting in poor airtightness and sound insulation. Reduce functionality.

In addition, with method (■), when the shoji is pulled together and the airtight material of the shoji stile and the sash frame are brought into contact, since both are flexible, it is difficult to apply pressure uniformly along the length of the stile, and the airtight material may There were drawbacks such as the waveform, gaps, and capillary action.

This invention was made by focusing on the above-mentioned drawbacks of the conventional structure.

This will be explained below with reference to the illustrated embodiments.

Figure 1 is an internal view of this shoji, and Figure 2 is its A-A.
The sectional view, FIG. 3, is a BB sectional view.

In this figure, an airtight material 2 is fitted into a groove 3 on a sash frame 1 facing outdoors.

The airtight members 2 of the upper frame 1a and the lower frame 1b are installed in two stages at positions facing the frames of the inner and outer shoji, and are continuous at positions facing the door frame 4.

Further, the airtight material 2 that abuts the outer shoji is jutted out with a step toward the outside of the room than the airtight material 2 that abuts the inner shoji.

An inner shoji 5 and an outer shoji 6 are fitted into this sash frame 1, and grooves 8 are provided along the longitudinal direction on the indoor side edges of the upper and lower frames 7 of the sash 6.

The side walls of these two upper and lower grooves along the upper and lower edges of the stile 7 respectively protrude toward the interior of the room, forming a protrusion 9 that continues in the longitudinal direction of the stile.

An elastic band 10 is provided in the groove 8 at the proximal end of the protrusion 9.
The elastic band 10 is attached to the protrusion 9 from its edge tip to its proximal end.

In addition, there is a groove 11 along the longitudinal direction on the indoor side of the door frame 4 of the outer shoji 6, into which an elastic band 12 is fitted, and its upper and lower ends are continuous with the elastic band 10 of the upper and lower frame 7.

In addition, the short roots 13 of the inner and outer shoji 5 and 6 and the upper and lower frames 7 of the inner shoji 5 have contact wall surfaces 14 that abut against the airtight material 2 of the sash frame 1.
is formed.

FIG. 2 shows a state in which the crescent 15 is locked and the inner and outer shoji 5, 6 are drawn toward the sash frame 1, the airtight material 2 of the sash frame 1 and the contact wall surface 14 of the inner and outer shoji frames are in contact with each other, and the outer shoji 6 is in contact with the airtight material 2 of the sash frame 1. The elastic band 12 of the door frame 4 contacts the door surface of the inner shoji screen to maintain airtightness.

4, A and B are enlarged views of the lower ends of the inner and outer shoji 5, 6 in FIG. 3, and FIG. 4 shows the shoji in a state where it is drawn into the sash frame.

In figure A, there is a groove 8 along the indoor edge of the outer shoji 6 and lower stile 7.
The lower wall thereof protrudes to form a protrusion 9.

An elastic body 10 is attached from the edge tip to the base end of the protrusion 9, and is fitted into the groove 8 for a fixed period of time.

When the crescent is unlocked, as shown in Figure A, the edge tips of the protrusion 9 and the elastic body 10 do not come into contact with the airtight material 2 of the sash frame.

Figure B shows the locked state and the inner and outer shoji drawn toward the sash frame. It is closed to.

Note that the abutting wall surface 14 of the inner shoji stile also abuts against the airtight material 2 to maintain airtightness.

As mentioned above, the airtight structure of this invention is characterized by providing a ridge that continues in the longitudinal direction of the frame on the side where the sash frame airtight material is attached to the shoji stile, and an elastic body is attached from the tip of the edge of this ridge to the base end. The protrusions and the edge tips of the elastic body are brought into contact with the airtight material of the sash frame to maintain airtightness.

In this structure, airtightness is maintained by the airtight material attached to the sash frame and the ridges of the shoji, and the elastic band attached to the sash serves as a buffer between the airtight material and the ridges of the sash frame.

Therefore, the protrusions do not damage the airtight material and can maintain airtightness for a long period of time.

Further, since the elastic band and the protrusion form a double layer and abut against the airtight material, airtightness can be further ensured.
