Description

[Detailed Description of the Invention] Industrial Field of the Invention The present invention is an internal-operated pulling method in which an indoor shoji (hereinafter referred to as an internal shoji) opens and closes when an outdoor shoji (hereinafter referred to as an external shoji) is killed. The present invention relates to a sash, and more specifically, to an airtight maintenance of an internal-moving type pulling sack.

2. Description of the Related Art Conventionally, the applicant of the present invention has filed an application for the above-mentioned internal-moving type pulling sash as Japanese Utility Model Laid-Open No. 60-41494 "Airtight sash with movable internal shoji". In this sash, at least a lower frame airtight member mounted between the lower frame of the window frame and the lower frame of the inner shoji is provided at least vertically. And
When the sliding door is pulled to the outside of the room and closed, the space formed between the double lower frame airtight members is made airtight by communicating with the outside through the drain holes formed in the lower frame. It is increasing the nature.

Problems to be Solved by the Invention In the above-mentioned inward-moving type pulling sash by the applicant, since the structure of the lower frame is complicated and the airtight material is exposed to sunlight and rain wind, the airtight material easily ages. However, there are problems that rain wind and wind easily enter due to the difference between the external pressure and the internal pressure, and that it requires drainage holes for drainage, resulting in high cost.

Means for Solving the Problems In view of the above problems of the conventional device, the present invention is such that the lower frame is inserted between the guide side piece and the outdoor side piece of the lower frame of the inner shoji on the outside of the guide rail. A rising piece is provided on the inner wall of the sliding door, and an intermediate piece is provided between the indoor side piece and the outdoor side piece, the intermediate piece protruding downward on the outside of the guide rail and on the indoor side of the rising piece. The airtight material is attached to either one of the rising piece or the intermediate piece so as to perform a seal between the intermediate piece and the intermediate piece, and the upper frame except the lower frame, the summing frame, and the door end frame. An airtight material for airtightness is attached to the window frame or the three frame members.

Action When the inner sliding door is closed and the inner sliding door is pulled toward the outside of the room, the space between the middle piece of the lower frame and the rising piece of the lower frame is closed by the airtight material. Further, in this state, the internal space between the outdoor piece and the intermediate piece of the lower frame of the internal shoji is opened to the outdoor side. Therefore, when rain wind blows on the outdoor side of the inner shoji in that state, the rainwater flows down on the outdoor side surface of the outdoor side piece of the lower inner shoji frame and flows down to the outdoor side of the rising piece. In addition, the internal space of the lower frame becomes equal in pressure to the outdoor space, and rainwater can be prevented from entering the internal space. As a result, it is possible to prevent rainwater from spraying on the seal surface of the airtight material, and to prevent rainwater from entering the room through the seal surface portion.

At the same time, the pieces 32 and 33 move in the vertical direction, and the airtight members 34 and 35 attached to the pieces 32 and 33 are pressed against the upper and lower frames 3 and 2 and the airtight member 28 to move the upper and lower portions of the summoning frame 15 together. Both ends and the upper and lower frames 3 and 2 are closed so that the entire circumferential surface of the inner shoji 12 is kept completely airtight. In the above case, since the intermediate piece 30 and the rising piece 7 are sealed via the airtight material 23, the airtight material 2
The gap between the sealing surface of No. 3 and the sealing surface of the airtight material 28 attached to the assembly stand 17 can be reduced, and as a result, the pieces 32,
The airtight materials 34 and 35 of 33 can easily close the upper and lower parts of the summing frame. Also, the outdoor side piece 14b of the lower frame 14
The rising piece 7 rises inside the room, and the inner space 14 of the lower frame
Since d is open to the atmosphere, rainwater sprayed on the outdoor side of the inner shoji 12 travels along the outdoor side surface of the lower frame 14 and flows down to the low step portion 6b. Lower frame 1
Since the internal space 14d of No. 4 communicates with the atmosphere from below the lower end 14c and is at a constant pressure with the atmosphere,
It is difficult for rainwater to be blown into d, and it is possible to prevent a large amount of rainwater from spraying on the sealing surface of the airtight material 23, which can prevent rainwater from entering the room through the sealing surface portion.

The present invention can be implemented by other embodiments described below. In the above, the airtight material 23 for sealing the lower frame 14 is the airtight material fitting groove 22 formed on the rising piece 7.
However, it may be directly attached to the intermediate piece 30 of the lower frame 14. Similarly, the mounting positions of the airtight members 25, 26, 28 for sealing the upper frame 13, the door frame 16 and the assembling frame 15 are not limited to the above, and the three frame members can be sealed. Any place can be changed as appropriate.

Effects of the Invention As described above, in the present invention, if the inner shoji is closed and then brought into the retracted state, even if rainwater is sprayed on the outside of the inner shoji, the inner space at the lower end of the lower frame becomes atmospheric. Since pressure is applied, rainwater can be prevented from entering the sealing surface of the airtight material between the rising piece and the intermediate piece, rainwater can be prevented from collecting on the airtight material and the rising piece, and wind and rain due to the airtight material can be prevented. The effect of preventing entry into the room can be enhanced. Also, since the rising piece of the lower frame provided on the outdoor side of the guide rail and the intermediate piece of the lower frame are sealed with the airtight material, the sealing surface of the airtight material is used as the outdoor piece of the lower frame. It is possible to bring them closer to each other, and as a result, it is possible to satisfactorily close the gaps between the upper and lower parts of the assembling frame, and the lower frame, thereby achieving high airtightness.
