のである。(Function) In the hinge of the present invention, when both the hinge bodies 12a, 12b are expanded when the plate bodies 3, 3 are in a closed state, the spring body 30 comes into contact with the flat cam part 25a of the cam 25, and the stopper 24 is in contact with the connecting edge 16b of the hinge main body 12b of the hinge main body 12b,
a, 12b elastically held in the expanded state, and
Hinge bodies 12a, 12 in the opening direction of the plates 3, 3
When b rotates, the contact between the spring body 30 and the flat cam portion 25a of the cam 25 is released, and the spring body 30 is brought into contact with the arcuate surface cam portion 25b and is released from being held, and both hinge bodies 12a, 12b is rotated. and,
When the plates 3, 3 are operated from the open state to the closing direction, the spring body 30 comes into contact with the flat cam part 25a from the circular arc surface cam part 25b of the cam 25 before it is completely closed, and the spring body 30 contacts the flat cam part 25a. Spring body 30
A force in the closing direction acts on the planar cam portion 25a, and the stopper 23 closes the other hinge body 12b.
Since the cam 25 is in contact with the inner surface of the hinge shaft 2, the pressing force in the closing direction of the plates 3, 3 can be reduced.
This cam 2
Since the spring body 30 that abuts on the support shaft 29 is wound around the support shaft 29, it is easy to assemble and can be assembled compactly.

Mounting holes 36 are formed at three locations respectively, and a plurality of thin parts 37 are formed on the outer periphery of the rising portion 13a of one of the hinge bodies 12a.
Inwardly bulging protrusions 38 are formed at several locations at the center and peripheral edge of 2b.
次に、この実施例の作用を説明する。 Next, the operation of this embodiment will be explained.

は円弧面部9,9に形成されている。 A pair of door bodies 3, 3 rotatably connected by a hinge 11 are attached to the back surface 3 of the connected edges 7, 7.
Each hinge body 12a, 1 is attached at two or more locations b, 3b.
The outer periphery of 2b has a circular inner diameter and a thickness of A so that it can be fitted.
(for example, 5 mm) deep, and the surfaces 3a, 3a sides of the edges 7, 7 are formed into arcuate portions 9, 9, respectively.

Bの例えば1mm離反した位置に配置される。 Then, align the edges 7, 7 of the door bodies 3, 3, fit the hinge bodies 12a, 12b of each hinge 11 into the respective recesses 8, 8 of the edges 7, 7, and insert the hinge bodies 12a, 12b of each hinge 11 into By screwing in the set screw 50, the hinge 11 connects both the door bodies 3, 3 and is fixed to the door bodies 3, 3. When the hinge 11 is in a fixed state, the center of the hinge shaft 20 is at a position between the edges 7, 7 of the door bodies 3, 3, and at a distance of, for example, 1 mm of thickness B from the back surfaces 3b, 3b of the door bodies 3, 3. will be placed in

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.
さらに、扉体3,3を折畳んだ状態で、扉体

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.
また、ヒンジ軸20と扉体3,3の裏面3b,

れば、厚みBを0mmに近付けて設定してもよい。 In addition, the hinge shaft 20 and the back surface 3b of the door body 3, 3,
The reason why the width B with respect to 3b is set in the range of 1 to 3 mm is to take into account warping of the door bodies 3, 3, and even if the dimensional accuracy of the edges 7, 7 of the door bodies 3, 3 is accurate. For example, the thickness B may be set close to 0 mm.

2b into the recesses 8, 8 of the door bodies 3, 3, the hinge shaft 20 of the hinge 11 is positioned.
center and edges 7, 7 of both door bodies 3, 3 and back surface 3
b, 3b and the position between the edges 7, 7 of both door bodies 3, 3 are in a predetermined arrangement. especially multiple hinges 1

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.
