る。 In addition, in the parallel state of the door bodies 3, 3, the hinge 11
Both hinge bodies 12a and 12b are in a parallel state, and the contact part 33 of the spring body 30 is elastically abutted against the flat cam part 25a of the cam 25 of the camshaft 21, and the stopper 23 is in contact with the other hinge body 12b. Abutting against the inner surface, the door bodies 3, 3 are held in their parallel state. Therefore, by this hinge 11, the door bodies 3, 3
is held in a state where the front surface of the furniture body 1 is closed.

When the cam 2 comes into contact with the cam 2, the urging force of the contact portion 33
5 is rotated counterclockwise in FIGS. 3 and 4, and the abutting portion 33 abuts against the outer peripheral surface of the cylindrical portion 22 of the camshaft 21. At this time, the stopper 24 protrudes from the notch 26 formed in the connecting edge 16a of one hinge main body 12a and the other hinge main body 12b
The cam shaft 2 is brought into contact with the edge surface of the connecting edge 16b of
1 is prevented from rotating. When the contact portion 33 of the spring body 30 is in contact with the outer peripheral surface of the cylindrical portion 22,
The contact part 33 is only in pressure contact with the cylinder part 22, and the contact part 33 slides on the outer circumferential surface of the cylinder part 22, and the door body 3,
3 can be folded.

ある。 Furthermore, when the door bodies 3, 3 are folded, the gap C between the edges 7, 7 of the door bodies 3, 3 has a maximum value twice the thickness B. This is because the center of the hinge shaft 20 is displaced from one door body 3 and the other door body 3 by a thickness B. For example, if the thickness B is 1 mm, the gap C will be 2 mm at maximum, This gap C
With this value, even if you accidentally place your finger between the edges 7, 7, it will not get caught between them, so you will not be caught and it is safe.

また、扉体３，３の縁部７，７には円弧面部
９，９が形成されているため、扉体３，３の縁部
７，７間に指が挟まれるのが防止される。 Further, since the edges 7, 7 of the door bodies 3, 3 are formed with arcuate surface portions 9, 9, fingers are prevented from being caught between the edges 7, 7 of the door bodies 3, 3.

れる。(Effect of the invention) According to the invention, when both hinge bodies are expanded when the plate body is closed, the spring body contacts the cam and elastically maintains the expanded state of both hinge bodies, so that the plate body When the hinge body is rotated in the opening direction, the contact between the spring body and the cam is released, the holding is released, and both hinge bodies are rotated.Moreover, when the plate body is operated from the open state to the closed direction, it is completely closed. Before closing, a force in the closing direction is applied by the action of the cam and the spring, reducing the pressing force on the plate in the closing direction, and the cam is supported by a cam shaft fitted to the hinge shaft and comes into contact with this cam. Since the spring is wrapped around the support shaft, it is easy to assemble and can be assembled compactly.
