When the crank handle (35) is rotated to the right, the worm gear (38) is rotated in the direction of arrow F, the drive arm (39) opens the shoji (2) via the transmission rod (40), and the opposite left side. Close by rotating. Instead of this handle, a worm (36) may be driven by a motor (not shown). Further, the shoji may be opened and closed by a motor through an appropriate transmission means without using the worm gear mechanism.

Means (11) for pulling the shoji (2) toward the indoor side
The two racks (44), (45) fixed to the vertical end of the vertical frame (9) on the free end side of the shoji (2) and the window facing the end surface of the vertical frame (9). The frame (1) is provided with two pinions (46) and (47) which are arranged above and below the vertical frame (10) and engage with the racks (44) and (45). Pinion (46), (4
7) is connected by a transmission rod (48) so as to rotate integrally. The shaft (49), which extends vertically from each pinion (46), (47),
(50) is rotatably inserted in the bearing parts (53), (54) of the brackets (51), (52). The brackets (51), (52) are fixed to the vertical frame (10) of the window frame (1).

When the shoji (2) is open, the rack (4
4) and (45) deviate from pinions (46) and (47) (Figs. 4 and 6). In that state, when the handle (35) is rotated counterclockwise, the lower frame (4) of the shoji (2) is attracted by the transmission rod (40) to close the shoji (2). At that time, the lower rack (44) moves inward (arrow G) and moves the lower pinion (46) into the arrow H.
Rotate in the direction. At the same time, the upper pinion (47) rotates in the same direction (H) via the transmission rod (48) and the upper rack (45).

When the handle (35) is rotated to the right when the shoji (2) is closed, the lower frame (4) of the shoji (2) is pushed outward by the transmission rod (40), and the shoji (2) )open. At that time, the upper and lower racks (44) and (45) move in the direction opposite to the arrow (G) while rotating the pinions (46) and (47), and come off the pinion (Figs. 4 and 6).

The lower end surface of the cylindrical boss portion (57) of the lower pinion (46) is always supported by the upper end surface of the bearing portion (53). The lower end surface of the boss (57) is a relatively raised arc-shaped horizontal surface (58).
And a descending arc-shaped horizontal plane (59) and a slope (60) connecting these horizontal planes (FIG. 8). The upper end surface of the bearing portion (53) is also formed by an arc-shaped horizontal surface (61) that is relatively raised, a descending arc-shaped horizontal surface (62), and an inclined surface (63) connecting these horizontal surfaces (Fig. 8). .

When the shoji (2) is completely open, the horizontal surface (58) of the pinion (46) engages with the horizontal surface (62) of the bearing portion (53), and the horizontal surface (59) of the pinion (46) is the bearing. It engages with the horizontal plane (61) of the part (53), and the slope (60) of the pinion (46) meshes with the slope (63) of the bearing part (53), and the meshing with the pinion (46), (47). It is held by the gravity of the transmission rod (48) (A in FIGS. 4 and 9).

When the shoji (2) is completely closed, the slope (60) of the pinion (46) rises while sliding on the slope (63) of the bearing portion (53), and the horizontal plane () of the pinion (46) ( 58) rides on and is supported on the horizontal surface 61 of the bearing portion 53 (B in FIGS. 5 and 9).

When the shoji (2) is opened from the closed position until the rack (44) is removed from the pinion (46), the slope (6) of the pinion (46) is
0) reaches a position where it partially engages the slope (63) of the bearing (53) and stops (C in FIG. 9). In that state Pinion (46),
(47) and the gravity of the transmission rod (48) on the slope (60) of the pinion (46)
Slide down on the slope (63) of the bearing part (53), and the horizontal surface (58)
The horizontal plane (62), the slope (60) and the slope (63), and the horizontal plane (59) and the horizontal plane (61) are returned to the positions where they mesh with each other (A in FIGS. 4 and 9). As a result, the pinions (46) and (47) are replaced by the racks (44) and (4
5) Stand by at the start position where it engages (Fig. 4, Fig. 6). The slopes (60) and (63) may be omitted, and a spring (not shown) that biases the pinion (46) toward the standby position may be used.

A hinge (not shown) may be used as a means for suspending the window shoji (2) in place of the restraint (7),
Other publicly known ones are appropriately used.
