In (a), 30 is a hinge after completion of assembly, and the relative rotation restraining means 40 is a space portion 32b-1 constituted by the shaft portion 31c of the lower hinge piece 31 and the inner surface of the cylindrical base portion 32b of the upper hinge piece 32. Everything is stored in (FIG. 1).
[0024]
As shown in FIG. 2B, the attachment portion 31a of the lower hinge piece 31 is fitted into the groove 1a-1 formed in one panel 1a, and the screw 4 is inserted through the insertion hole 1a-2 of the panel 1a. In the same manner, the attachment portion 32a of the upper hinge piece 32 is fitted into the groove 1a'-1 formed in the other panel 1a ', and the screw 4 is inserted into the insertion hole of the panel 1a'. It is attached by being inserted from 1a′-2 and screwed into the screw hole 32a ′ of the attachment portion.
[0025]
FIG. 2 (b) shows that the panels 1a and 1a ′ are mounted with 180 degrees open, and the pin 31b-1 is located at the end of the arc groove 32b-3 formed over a range of 90 degrees. Is engaged. When the panel 1a is rotated 90 degrees counterclockwise from this state and restrained and held at that position, the panel 1a is rotated counterclockwise with respect to the panel 1a '. At that time, the pin 31b-1 provided on the lower hinge piece 31 can be rotated along the circular arc groove 32b-3 up to 90 degrees, but is restricted so as not to be able to rotate beyond that angle. The movement stops when it rotates.
[0026]
While the panel 1 a is rotated 90 degrees to the left, the cam ring 34 that rotates integrally with the shaft portion 31 c of the lower hinge piece 31 rotates 90 degrees with respect to the cam groove ring 33. This is a state in which the mountain cam 34a of the cam ring 34 in FIG. 1 is engaged with the cam groove recess 33b of the cam groove ring 33 when both panels 1a and 1a 'are aligned in the state of FIG. When the panel 1a rotates 90 degrees, the mountain-shaped cam 34a moves to the adjacent cam groove recess 33b that is 90 degrees apart. In order to overcome the cam mountain 33b 'during this movement, an elastic body, in this embodiment, is used. The spring 36 must be compressed.
[0027]
Since the force compressing the spring 36 becomes the movement restraining force of the panel 1a or 1a ', when the panel 1a is rotated 90 degrees counterclockwise from the state in which both the panels 1a and 1a' are aligned, the panel 1a is moved to its position. It will be restrained and held so that it cannot move.

The length is possible.
[0032]
Further, the rotation of the hinge 30 applies a constant force to each of the panels 43 and 44 to close the opening by 90 ° about the hinge 30 and constrain the opening that is constrained at that position and conversely. In order to open, by applying a certain force to the panels 43 and 44, the panel 43 and 44 are opened by turning 90 ° and are restrained at that position. As a result, the partition 41 is stable both in the open state and in the closed state, so that the panel does not rattle during use or movement of the partition.
[0033]
FIG. 4 is an exploded perspective view in which a pole is applied between the upper and lower hinges. Cap upper portions 37b and lower hinge convex portions 31d having the same diameter are formed in advance on the upper and lower ends of the hinge 30, A pole 5 having an insertion hole 5a is fitted between the cap convex portion 37b of the lower hinge 30 and the lower hinge convex portion 31d of the upper hinge 30.
[0034]
FIG. 5 is a perspective view in which the hinge assembly having the pole of FIG. 4 disposed in the middle is applied to the partition, and between the upper hinge 30 and the lower hinge 30 that rotatably connect the panels 51 and 52.
