Description

[Detailed Description of the Invention] The present invention relates to an airtight device for horizontal axis rotation, and was devised for the purpose of preventing the rotating window from opening due to wind pressure as much as possible.

In other words, due to the strength of the sash profile of horizontal rotating windows, there is a gap between the window frame and the shoji frame, and wind enters into this gap from below, reducing the wind pressure. The receiving shoji is moved indoors using the horizontal axis of the shoji as a fulcrum at its upper end, that is, the upper stile, and the window may be opened due to wind pressure.

The present invention avoids such defects in transverse rotating windows.

The drawing shows an embodiment of the airtight device for a horizontally rotating window according to the present invention, where A is a window frame, B is a shoji that is rotatably fitted around the window frame A (not shown) as a fulcrum, and A pair of elastic pieces 2, 2 made of rubber are attached to the lower part of the side surfaces of the vertical frames 1, 1 of the shoji B on the outdoor side, and protrude in the direction of the window frames 3, 3, and the gap between the elastic pieces 2, 2 is 4, an elastic piece 5 made of rubber that is inserted when the shoji is closed is provided on the vertical frame of the window frame A, protruding inward. Although the airtight material 8 provided at the outdoor end of the shoji frame 1 or the window top frame 7 prevents wind from entering the gap 9 existing between the window frame A and the shoji B, the horizontal axis rotation Due to the function of the window, there is a gap 12 between the shoji lower stile 10 and the window lower frame 11 that communicates with the gap 9.
The wind enters the air gap 9 from this air gap 12, and this blows into the second airtight area, especially the upper frame 7 and the shoji upper frame 13.
In the conventional device, there was a risk that the window would gradually open from the second airtight part 14 due to wind pressure.

Since the present invention has the above-mentioned configuration, the elastic pieces come into contact with each other due to wind pressure and can prevent wind from entering, thereby avoiding the conventional defects.

In the embodiment, the pair of elastic pieces are arranged on the shoji frame, but it goes without saying that the pair of elastic pieces may be provided on the side of the frame. The elastic piece does not have to be made of rubber. Reference numeral 15 indicates an airtight material.
