Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an airtight device for a rotating window in which a shoji is rotatably assembled to a window frame via a horizontal or vertical axis.

Conventional technology and problems A shoji is rotatably assembled to a window frame via a horizontal axis or a vertical axis at an intermediate position of a shoji stile, and a groove formed on the outer periphery of one half of the shoji around the horizontal axis or vertical axis is attached. , attaching an airtight material with a hollow cross section that abuts indoors and outdoors to one half of the window frame corresponding to the one half of the shoji;
An airtight material with a hollow cross section that is located on the same plane in the indoor and outdoor directions with respect to this airtight material, and that is in contact with the outer periphery of the other half of the shoji with the horizontal axis or the vertical axis as the center in the indoor and outdoor directions. A rotary window airtight device is known in which the rotary window is attached to a groove provided in the other half of the window frame.

In this known structure, both ends of the airtight material on the shoji side and the airtight material on the window frame side are in contact with each other to ensure airtightness on the horizontal axis or vertical axis.

However, since the airtight material having a hollow cross section is made of rubber, it may shrink over time, making it difficult to maintain the above-mentioned abutting state, and the airtightness may be reduced.

Means for Solving the Problems The present invention was devised for the purpose of eliminating the drawbacks of the above-mentioned known air-tight device for a rotating window. , a solid elastic piece is inserted into the end of each airtight material located near the horizontal axis or the vertical axis, and the solid elastic piece contacts the tip of the elastic piece provided on the other airtight material when the shoji is closed, and the elastic piece is The structure is such that the airtight material is engaged with the cutout edge of the groove.

Embodiment The drawing shows an embodiment of the airtight device for a rotating window according to the present invention, where A is a window frame consisting of an upper frame 1a, a lower frame 1b, and left and right vertical frames 1c, 1c, and B is a shoji screen.
The shoji B is rotatably fitted to the window frame A by the rotating shaft 2 so that when opened, one half of the upper half is located indoors and the other half of the lower half is located outdoors. A piece 3 is provided on the outer periphery of one half of the upper half of this shoji B, and a groove 4 provided in this piece 3 is inserted into the outdoor side of the upper half of the window frame A when the shoji is closed. An airtight material 6 is attached which abuts against the indoor side surface 5' of the provided piece 5.

Also, in the outdoor part 7 of the other half of the lower half side corresponding to the upper half side of the window frame A, there is a groove 4 that is the same in the indoor/outdoor direction as the groove 4 provided in the shoji B when the shoji is closed. A groove 8 located on a plane is provided, and a shoji B is placed in the groove 8.
An airtight material 6' is attached to the indoor side surface 9' of the piece 9 provided on the outer periphery of the other half of the lower half corresponding to the upper half of the shoji.

Tip pieces 4', 8 forming the grooves at both longitudinal ends of the grooves 4, 8 (near the rotating shaft 2) of the shoji side piece 3 and the window frame side piece 7 forming the grooves 4, 8; ' are cut out 3', 7', and the ends of the hollow airtight members 6, 6' attached to the grooves 4, 8 are cut out at the edges 3' of the notches 3', 7'.
a, 7'a, and solid elastic pieces 10, 10' are inserted into these ends and bonded. The elastic pieces 10, 10' are connected to the main body parts 10a, 10'a and the insertion part 1.
0b, 10'b, and the insertion part 10b, 1
0'b is inserted into the airtight material 6, 6' and adhered, the main body parts 10a, 10'a are locked to the notch edges 3'a, 7'a, and the tips 10a of the main body parts 10a, 10'a are ',1
0′a′ contact each other when the shoji is closed, and the rotating shaft 2
It is constructed to ensure airtightness in the vicinity.

When the shoji is closed, the airtight material 6 provided on the upper half of the shoji B is attached to the indoor side surface 5' of the window frame piece 5, and the other half of the lower half of the shoji B is One half abuts against the airtight material 6' provided on the window frame A side on the indoor side surface 9' of the piece 8 of the shoji B so as to be positioned on the same plane in the indoor/outdoor direction, thereby ensuring airtightness. Further, the main body tips 10a' and 10'a' of the elastic pieces 10 and 10' abut each other between the airtight members 6 and 6', thereby maintaining airtightness.

Although the elastic pieces 10 and 10' are made of rubber, they may also be made of synthetic resin.

Further, although the embodiment is configured with the rotation axis 2 as the horizontal axis, the present invention can also be applied to a vertical axis, that is, a vertical axis rotating window.

Effects of the invention As mentioned above, since the airtight material is made of rubber, it will shrink over time and there is a risk that it will not be possible to ensure airtightness near the rotation axis. A solid elastic piece is inserted into the end of the airtight material and is locked to the notch edge of the groove, which prevents the airtight material from shrinking over time and reduces its airtight function. It can be prevented.
