Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a smoke exhaust window that exhausts smoke that fills a room in the event of a fire or the like.

[Conventional technology]

As shown in Japanese Utility Model Application No. 58-20072, the upper part of the window frame and the upper part of the shoji are pivotally connected, a stay damper is connected across the window frame and the shoji, and the shoji is opened by the elastic force of the stay damper. Smoke extraction window.

As shown in Japanese Utility Model Publication No. 59-30157, the lower part of the window frame and the lower part of the shoji are pivotally connected, and a connecting piece is attached between the vertical frame of the window frame and the sliding piece that is movable up and down. A smoke evacuation window that allows the shoji to open under its own weight.

[Problems to be solved by the invention] With the former type of smoke exhaust window, the stay damper is visible from inside the room, resulting in poor appearance.

With the latter type of smoke exhaust window, when the shoji is closed, the connecting piece is stored between the window frame and the shoji, making it look better, but on the other hand, the lower part of the shoji may rotate relative to the lower part of the window frame. Since the shoji is opened at the pivot point between the lower part of the shoji and the lower part of the window frame, rainwater, etc. can easily accumulate in the joint, leading to early corrosion.In addition, the torsion coil spring installed at the pivot joint is used to urge the shoji to open. Therefore, due to problems such as installation space, the opening force of the shoji cannot be increased very much, and the opening time takes a long time, making it undesirable as a smoke evacuation window.

In other words, smoke exhaust windows are required to be opened quickly because they are used to exhaust smoke that has filled a room in the event of a fire.

In addition, since the shoji is held in the open state by the aforementioned torsion coil spring, it may rotate toward the closed side when it is blown by strong winds, rattling the shoji and preventing damage to the pivot joints. be.

Therefore, the present invention has been developed to prevent rainwater from accumulating at the joint between the shoji and the window frame, and to increase the opening force of the shoji, as well as to improve the appearance of the shoji when it is closed. The purpose is to provide a window.
