Description

  The present invention relates to a fitting that opens and closes a shoji attached to a window frame via a shoji support device by driving the shoji support device.

  In general, a vertical extension window or a horizontal extension window is used to open and operate a shoji attached to the window frame via a shoji support device called a friction stay so as to protrude vertically or horizontally from the window frame. When opening and closing the shoji, the drive mechanism for driving the shoji support device is rotated by a handle, and the shoji support device is operated directly from the drive mechanism, or the shoji is operated in cooperation with the drive mechanism and the shoji support device. It is done by letting out.

Although the shoji support device is disposed above and below the shoji when the shoji is closed, the opening / closing drive mechanism and the operation handle protrude toward the indoor side of the window frame. Therefore, whenever the opening / closing is necessary, the handle can be turned to open / close the shoji.
