Description

  The present invention relates to a sash in which a shoji is rotated around a peripheral edge to open and close an opening.

  Conventionally, in an opening window such as a protruding window, a shoji 91 is attached to a frame 92 using a hinge 90 as shown in FIG. The hinge 90 is fixed to the shoji 91 and the frame 92 with screws 93a and 93b, respectively. However, the hinge 90 is subjected to a strong force due to the weight of the shoji 91 and the wind pressure, and further, the smoke is protruded and the window is faced downward by a damper. Since the urging force is also applied and these forces must be borne only by the screws 93a and 93b, the number of the screws 93a and 93b inevitably increases (usually five hinges and one frame for each hinge). Therefore, workability when attaching the shoji 91 to the frame 92 is very poor. When the shoji is attached to the frame via the hinge, as shown in FIG. 8 (a), the hinge 90 is first attached to the shoji 91 with the screw 93a, and then the work is performed as shown in FIG. 8 (b). Since the person must support the shoji 91 and press the hinge 90 against the prospective inner circumferential surface of the frame 92, the position adjustment in the prospective direction and the left-right direction must be performed, so that the mounting operation cannot be easily performed.
