Description

[Detailed description of the invention] Industrial application field The present invention relates to an airtight device between a shoji and a window frame of a rotating window that rotates around a rotation axis, such as a vertical rotating window or a horizontal rotating window. .

Conventional technology As shown in Japanese Utility Model Publication No. 56-28315, an airtight material is placed around the window frame and the shoji screen four times in succession, and an auxiliary material on the window frame side is attached to one side of the rotation center of the window frame. At the same time, auxiliary material on the shoji side is attached to the other side of the shoji from the center of rotation, so that when the shoji is closed, the auxiliary material on the window frame side presses against the airtight material on the shoji side, and the auxiliary material on the shoji side presses against the airtight material on the shoji side. In addition to maintaining airtightness between the window frame and shoji by crimping it to the airtight material of the shoji, each auxiliary material is made of metal, so the shoji side auxiliary material attached to the rotating shoji and the fixed window frame can be attached. The window frame side auxiliary material and the shoji side auxiliary material cannot be brought into contact with each other near the center of rotation, and the window frame side auxiliary material and the shoji side auxiliary material There is known an airtight device in which airtight plates made of an elastic material are attached to each other and are abutted against each other, and the gap is closed at the abutting portions of the airtight plates.

Problems that the invention aims to solve: Since such an airtight device only has a pair of airtight plates that butt against each other, rainwater may enter the room from between the butt parts due to strong winds, etc. The effect is not very good.

Means and action for solving the problem Install the window frame side airtight block near the hinge attachment part of the window frame so that it contacts the window frame side attachment end and the window frame side airtight material, and install the hinge on the shoji. A shoji side airtight block is installed near the shoji side attachment end and the shoji side airtight material so as to maintain airtight contact therewith, and the opposing end surfaces of these blocks are made slopes that overlap each other,
Each interior surface is pressed against the exterior surface of the hinge, so that when the shoji is closed, both blocks are pressed against the opposite airtight material, and the opposing end surfaces overlap each other and are pressed by the hinge. The parts come into close contact with each other, which maintains airtightness around the hinge mounting part, and also prevents contact between the weight parts of both blocks due to strong winds, etc.
This was done so that there would be no gaps.
