Next, the assembling procedure will be described. First, the shaft 31c of the lower hinge piece 31 is inserted through the through hole 32b-4 formed in the bottom surface of the cylindrical base 32b of the upper hinge piece 32, and the pin 31b-1 is arcuate. Enters the groove 32b-3,
The two bases 31b and 32b are fitted until they come into contact with each other. Thereafter, the cam groove ring 33 is fitted into the cylindrical base portion 32b, and the cam ring 34 is fitted into the shaft portion 31c via key grooves.

On the lower surface of the cam ring 34, two mountain-shaped cams 34a are formed at an interval of 180 ° to form a cam groove ring 33.
The upper surface is provided with four cam groove recesses 33b at 90 ° positions on the circumference. The two rings 33 and 34 are considered so that the relative rotation of the two panels can be restrained at a predetermined angular position formed by the two panels, that is, 0, 90 or 180 degrees in the present embodiment. It has been designed.

At the time of assembly, the panel mounting portion 31a of the lower hinge piece 31 and the panel mounting portion 3 of the upper hinge piece 32

At 0 degree, the mountain-shaped cam 34a is brought into contact with the cam groove recess 33b.

Finally, the spring receiver 35, the spring 36, and the spring holding cap 37 are sequentially stacked on the cam ring 34, and the lower circumferential surface of the cap 37 is brought into contact with the upper circumferential surface of the cylindrical base 32b. A knock pin 38 is inserted through a screw hole 37a formed on the outer peripheral surface, and a cylindrical shaft convex portion 31c-2 formed on the upper end surface of the shaft portion 31c of the lower hinge piece 31 is knocked through the outer peripheral surface.
Insert into 2 'and engage with screw.

FIG. 2 shows a hinge and a part of the panel disposed between the side edges of both panels after the assembly is completed.
2A is a front view thereof, FIG. 2B is a plan view thereof, and FIG.
In (a), 30 is a hinge after completion of assembly,
The relative rotation restraining means 40 includes a shaft portion 31c of the lower hinge piece 31.
And the space portion 32b-1 (FIG. 1) formed by the inner surface of the cylindrical base portion 32b of the upper hinge piece 32.

As shown in FIG. 2B, the mounting 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 into the insertion hole 1a of the panel 1a.

And insert the screw 4 into the insertion hole 1a'-2 of the panel 1a '.
It is attached by inserting it and screwing it into the screw hole 32a 'of the attachment part.

FIG. 2B shows that the panels 1a and 1a 'are 180
It is shown that it is mounted in the open state, and pin 3
1b-1 is engaged with an end of an arc groove 32b-3 formed over a range of 90 degrees. When the panel 1a is to be rotated counterclockwise by 90 degrees from this state and the panel 1a is to be restrained and held at that position, the panel 1a is rotated counterclockwise with respect to the panel 1a '. At this time, since the pin 31b-1 provided on the lower hinge piece 31 can rotate along the arc-shaped groove 32b-3 up to 90 degrees, it is limited so as not to rotate beyond that angle, so that the panel 1a is 90 degrees. When it rotates, it stops moving.

During the 90-degree left rotation of the panel 1a, the cam ring 34 that rotates integrally with the shaft portion 31c of the lower hinge piece 31 rotates 90 degrees with respect to the cam groove ring 33. This is because when the two panels 1a and 1a 'are aligned in the state shown in FIG. 2B, the mountain cam 34a of the cam ring 34 in FIG. When the panel 1a rotates 90 degrees, the mountain-shaped cam 34a moves to the adjacent cam groove recess 3 90 degrees away.
3b, and during this movement, the cam peak 33b '
In order to get over the elastic member, the elastic body, in this embodiment, the spring 36 must be compressed.

Since the force for compressing the spring 36 becomes the movement restricting force of the panel 1a or 1a ', the two panels 1a, 1a'
When the panel 1a is rotated 90 degrees counterclockwise from the state where a 'is aligned, the panel 1a is restrained and held so as not to move at that position.

In this embodiment, the cam ring 34 is slidably engaged with the lower hinge piece 31 and the cam groove ring 33 is slidably engaged with the upper hinge piece. , Cam groove ring 3
3 may be respectively slidably engaged with the lower hinge pieces.

Up to now, the description has been given of the case where the panel 1a is rotated 90 degrees to the left. However, even if the panel 1a is rotated to the right, the mountain cam 34a similarly moves to another cam groove recess 33b 90 degrees away from the adjacent cam groove 33b. It will be held in position. At this time, it is needless to say that the arc groove is formed so as to be able to rotate counterclockwise.

In this embodiment, the panel is restrained and held at that position when the panel is rotated by 90 degrees. However, the range in which the arc groove 32b-3 is formed and the arrangement angle of the cam groove recess 33b are appropriately adjusted. By setting, it is possible to restrict and hold at an angle desired by the user without being limited to 90 degrees.

FIG. 3 is a plan view of a partition according to the present invention in which two panels are openably and closably attached via hinges to the front of a U-shaped panel having an open front. A shorter panel 43 is attached to the other side, and a longer panel 44 is attached to the right side via the hinge 30. The total length of the panel 43 and the panel 44 is equal to the opening of the U-shaped panel 42. It is long enough to close.

The hinge 30 is closed by 90 ° rotation about the hinge 30 by applying a constant force to the respective panels 43 and 44, and is constrained at that position, and conversely closed. To open the opening, the panel 43, 44 is opened by 90 ° rotation by applying a certain force to the panel 43, and is restrained at that position. As a result, the partition 41 is stable in both the open state and the closed state, so that the panel does not rattle during use or movement of the partition.

FIG. 4 is an exploded perspective view in which a pole is applied between the upper and lower hinges. A cap projection 37b and a lower hinge projection 31d of the same diameter are previously formed on the upper and lower ends of the hinge 30. The pawl 5 having the insertion hole 5a is fitted between the cap projection 37b of the lower hinge 30 and the lower hinge projection 31d of the upper hinge 30.

FIG. 5 is a perspective view in which a hinge assembly in which the pole of FIG. 4 is disposed in the middle is applied to a partition.
A resin pole 53 is mounted between the upper hinge 30 and the lower hinge 30 for rotatably connecting the panels 51 and 52, and the gap between the panels is closed by the two hinges 30 and the pole 53. Thus, the shielding effect of the partition 50 can be enhanced. In addition, it is possible to avoid the danger that the user will pinch his hand when the panel is opened or closed or moved.

Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and even if there are changes and additions without departing from the gist of the present invention. For example, the number of hinges provided between both panel side edges is not necessarily limited to two, and may be one considering the size of the panel and the degree of rotation stability. Three or more may be attached. .
