DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The case (1) has a generally rectangular parallelepiped shape and is formed by mutually parallel side walls (2) and (2) and other mutually parallel end walls (3) and (4). The front surface (5) and the rear surface (6) are open. A short outer flange (7) is formed on both side walls (2), (2) and the end wall (3), a long outer flange (8) is formed on the end wall (4), and further the end wall (3). Has a short outer flange (9) parallel to the short flange (7). These flanges (7),
(9) is fitted into the edge (12) of the mounting hole (11) of the shoji (10) (FIG. 7). The long flange (8) has holes (1

The pivot (20) is fitted into the bearing hole (21) and pivotally connected between the retracted position (unlocked position) and the projected position (locked position) so as to be swingably rotatable. doing.

The pivot (20) is a short axis erected on both side surfaces (18) of the stopper (16) and has a sectional shape on a diameter line connecting the semicircular partial circumferential surface portion (22) and both ends thereof. It is formed in a semicircle surrounded by a plane portion (23) (FIG. 8). The flat portion (23) of the pivot (20) is provided by the amount (30) that the stopper (16) rotates from the projecting position to the closed position with respect to the front surface (17) of the stopper (16).
Degrees) at an acute angle (FIG. 5).

The bearing holes (21) are formed in both side walls (2) of the case (1). The cross-sectional shape of this bearing hole (21) is a partial circumferential surface portion (24) between the semicircle and the circumference (points 25 and
33) and one end (25) of the partial circumferential surface to the center (2
It is formed in a partial circle surrounded by a radial plane portion (27) extending to 6). The central angle of the partial circumferential surface portion (24) of the bearing hole (21) is 210 degrees, the central angle of the partial circumferential surface portion (22) of the pivot (20) is 180 degrees, and the difference of 30 degrees is the pivot angle. The rotation angle is (20). For this purpose, the radial plane portion (27) of the bearing hole (21) is also required to be positioned at an
The stopper (16) is inclined at an acute angle by an amount (30 degrees) to rotate from the projecting position to the retracted position (FIGS. 5 and 8).

The pivot (20) is a guide groove (28) and a rear end of the side wall (2).
It is guided from (29) to the bearing hole (21). This guide groove (28) is also formed on both side walls (2) of the case (1) similarly to the bearing hole (21), and one end (30) thereof opens to the rear end (29) of the side wall (2). Thus, the pivot (20) can be inserted into the guide groove (28) or pulled out from the guide groove (28) (FIGS. 5 and 8).

The width of the guide groove (28) is determined by the radius of the pivot (20), and along the side edges (31) and (32) of the guide hole (28), the width of the pivot (20) is It can be moved only when the flat portion (23) and the partial circumferential surface portion (22) are in contact (FIG. 8). One side edge (31) of the guide hole (28) is located at the center (26) of the partial circumferential surface (24) of the bearing hole (21).
The other side edge (32) of the guide hole (28) is partially
4) is connected to the other end (33) (FIG. 8). The central portion (26) of the partial circumferential surface portion (24) where one side edge (31) of the guide hole (28) and the flat portion (27) of the bearing hole (21) intersect is the partial circumferential surface portion of the pivot (20). (twenty two)
And the center (26) is used as the center of rotation of the pivot (20) (FIG. 8).

The stopper (16) is assembled in the case (1) as follows. Align the flat part (23) of the pivot part (20) with the guide groove (2
8) According to the extension of one side edge (31) (FIGS. 5 and 8),
Insert the pivot (20) into the guide groove (28). In that state, the Axis (2
(0) into the guide groove (28), the flat part (23) of the pivot (20)
Then, the partial circumferential surface portion (22) reaches the bearing hole (21) while sliding on both side edges (31) and (32) of the guide groove (28) (FIGS. 6 and 8). Next, when the stopper (16) is rotated in the counterclockwise direction, the flat surface (23) of the pivot (20) has a partial circumferential surface (2) of the bearing hole (21).
While rotating about the central portion (26) of (4) as a fulcrum, the partial circumferential surface portion (22) of the pivot (20) slides and rotates along the partial circumferential surface portion (24) of the bearing hole (21) (FIG. 8). ). When the stopper (16) is rotated to the retracted position, the flat portion (23) of the pivot (20) hits the flat portion (27) of the bearing hole (21) (FIG. 2). This completes the assembly.

In the state of FIG. 2, when the left end (pressed portion) of the stopper (16) is pushed with a finger, the stopper (16) rotates clockwise to reach the protruding position (FIG. 7). At this position, the stop surface (19) of the stopper (16) is
0), and make contact with the opposing inner shoji (34) in parallel with the rear end surface (35) of the opponent's inner shoji (34).
4) Prevent opening. The plane part (23) of the pivot (20) is oriented horizontally in the drawing (FIG. 7).

Means for holding the stopper (16) at the retracted position and the projected position is provided between the stopper (16) and the case (1). As this means, one short protrusion (36) is erected on both side surfaces (18) of the stopper (16) (FIG. 5), and two holes (37) and (38) into which the protrusions fit are formed. They are formed on both side walls (2) of the case (1). Hole (37) is for the retracted position and hole (38) is for the protruding position. The fitting and disengagement of these holes (37), (38) and the projection (36) is performed by elastic deformation. When the stopper (16) is retracted, the protrusion (3
6) fits into the hole (37) and holds the stopper (16) in that position. When the stopper (16) is protruding,
(36) fits into the hole (38) to hold the stopper (16) in that position.
