 In order to solve the above-mentioned problems, in the present invention, a pair of mounting plates are provided with protrusions that are linearly arranged on one side, respectively, and a pair of mounting plates is provided with pins that penetrate the both protrusions. Opening and closing are connected, a square hole is formed on one of the facing surfaces of the protrusion of one mounting plate and the protrusion of the other mounting plate, and a piece and the piece of the other mounting plate are formed in the square hole. Incorporating an elastic body that is pressed against, a protrusion having a rounded tip is provided on the end face of the piece, and an engaging recess for engaging the protrusion is provided on the end face of the protrusion against which the piece is pressed. .

[0006]

[Action]

 According to the above structure, when the pair of mounting plates are rotated around the pin, the projecting portion of the piece engages with the engaging concave portion at a position where the projecting portion of the piece faces the engaging concave portion. Depending on the combination, the pair of mounting plates are stopped and held.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, a hinge according to the present invention has a pair of mounting plates 1a and 1b, a protrusion 2 is provided at a central portion of one mounting plate 1a on one side, and the other mounting plate 1a is mounted on the hinge. Two protrusions 3 and 3 are provided at both ends on one side of 1b, and the protrusion 2 of one mounting plate 1a is inserted between the two protrusions 3 and 3.

As shown in FIGS. 2 and 4, the protrusion 2 of the one mounting plate 1a is provided with a pin hole 4 penetrating from one end to the other end.

Each protrusion 3 of the other mounting plate 1b is provided with a square hole 5 penetrating from one end to the other end, and a rectangular piece 6 and the piece 6 are mounted on the one mounting plate 1a. The elastic body 7 that is pressed against the protrusion 2 is incorporated.

The piece 6 is provided with a pin hole 8 penetrating from one end surface to the other end surface, and a pin 9 is inserted into the pin hole 4 of the protrusion 2 on the mounting plate 1 a on one side of the pin hole 8.

The pin 9 has a pair of discs 9 a and 9 b at both ends, and each disc 9 a and 9 b is assembled in the square hole 5 by abutting on the outer end surface of the protrusion 3 of the other mounting plate 1 b. The bridge 6 and the elastic body 7 are prevented from coming off.

The square hole 5 formed in the projection 3 of the other mounting plate 1b is used as a blind hole for closing the outer end of the projection 3 to prevent the bridge 6 and the elastic body 7 from coming off, and the blind hole Both ends of the pin 9 may be supported by the closed end of the square hole 5.

A protruding portion 10 having a rounded tip is provided on a surface of the one mounting plate 1 a of the piece 6 facing the protruding portion 2, while the protruding portion 10 is provided on both end surfaces of the protruding portion 2. A plurality of engaging recesses 11 that are engageable with each other are provided at equal intervals in the circumferential direction.

As the above-mentioned projecting portion 10, a ridge extending in the radial direction is shown in FIGS. 2 and 4, but it may be a projection having a hemispherical tip as shown in FIG. The shape of the engaging concave portion 11 is determined according to the shape of the projecting portion 10. When the projecting portion 10 is a ridge, the engaging concave portion 11 is a groove extending in the radial direction. When the protrusion 10 is a protrusion, the engaging recess 11 is a hole. It suffices that at least one protrusion 10 is provided.

In the hinge configured as described above, one of the pair of mounting plates 1a and 1b is attached to an opening / closing member such as a lid or a door, and the other mounting plate is attached to a fixed member supporting the opening / closing member.

Now, for example, one mounting plate 1a is mounted on the fixed side member, the other mounting plate 1b is mounted on the opening / closing member, and the other mounting plate 1b is rotated around the pin 9 by the rotation of the opening / closing member. Then, the piece 6 assembled in the square hole 5 of the protrusion 3 also rotates around the pin 9. When the projecting portion 10 of the piece 6 faces the engaging concave portion 11 of the projecting portion 2 of the one mounting plate 1a, the piece 6 moves toward the projecting portion 2 of the one mounting plate 1a by the elastic force of the elastic body 7. The protrusion 10 engages with the engagement recess 11. The engagement prevents the other mounting plate 1b from rotating, and the opening / closing member mounted on the mounting plate 1b stops.

When the opening / closing member is pushed or pulled to apply a rotational force to the other mounting plate 1b in a state where the protrusion 10 and the engagement recess 11 are engaged, the protrusion 10 causes the opening edge of the engagement recess 11 to be opened. Then, the piece 6 is retracted against the elastic force of the elastic body 7, the protruding portion 10 is pulled out from the engaging concave portion 11, and the other mounting plate 1b is rotated about the pin 9.

When the projecting portion 10 faces the engaging recessed portion 11, the piece 6 is advanced to engage the projecting portion 10 with the engaging recessed portion 11, and the other mounting plate 1b is rotated by the engagement as described above. Will be stopped.

As described above, when the projecting portion 10 faces the engaging recessed portion 11, the piece 6 advances and the projecting portion 10 engages with the engaging recessed portion 11, and the plurality of engaging recessed portions 11 are provided in the circumferential direction. Therefore, the other mounting plate 1b can be stopped stepwise at each position where the protruding portion 10 faces the engaging recessed portion 11, and the opening / closing member connected to the other mounting plate 1b is opened / closed. Can be held stopped at.

In the embodiment, one projection 2 is provided on one mounting plate 1a and two projections 3 are provided on the other mounting plate 1b, but the number of projections 2 and 3 is not limited to this. It is not something that will be done.

[0022]

[Effect of device]

 As described above, in the present invention, when the pair of mounting plates are relatively rotated, the protrusion engages with the engagement recess at the position where the protrusion of the bridge faces the engagement recess of the protrusion. Since the mounting plate is relatively prevented from rotating, the opening / closing member connected to one of the pair of mounting plates can be stopped and held in the middle of opening / closing.
