[0001]

BACKGROUND OF THE INVENTION This invention relates to hinges.

[0002]

2. Description of the Related Art As a hinge for supporting an opening / closing member such as a cover of a bag, a door of furniture, or a door for opening / closing an entrance of a building,
2. Description of the Related Art It is conventionally known that a cylindrical portion is provided on one side of a pair of mounting plates, and a pin is inserted into the cylindrical portion to connect the pair of mounting plates to be freely opened and closed.

[0003]

In a conventional hinge comprising a pair of mounting plates, an opening / closing member such as a lid or a door cannot be stopped and held during opening / closing, and the opening / closing member is stopped midway. In such a case, it is necessary to separately attach a stop fitting.

An object of the present invention is to provide a hinge capable of holding an opening / closing member such as a lid or a door in a stopped state during opening / closing.

[0005]

In order to solve the above-mentioned problems, in the present invention, one of a pair of mounting plates is mounted.
A protrusion is formed on one side of the plate, and the protrusion is formed on one side of the other mounting plate.
A plurality of protrusions are provided at intervals at which the

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the hinge according to the present invention has a pair of mounting plates 1a and 1b, and one of the mounting plates 1a.
A protrusion 2 is provided at the center of one side, and two protrusions 3 are provided at both ends of one side of the other mounting plate 1b. One mounting plate 1a is provided between the two protrusions 3 and 3. the projection 2 is fitted.

As shown in FIGS. 2 and 4, the protrusion 2 of one of the mounting plates 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 square piece 6 is inserted into the square hole 5 and the piece 6 is attached to one mounting plate 1a. And an elastic body 7 that presses against the projection 2 is incorporated.

The piece 6 is provided with a pin hole 8 penetrating from one end face to the other end face, and a pin 9 is inserted into the pin hole 8 and the pin hole 4 of the projection 2 of one of the mounting plates 1a.

The pin 9 has a pair of discs 9a and 9b at both ends, and the discs 9a and 9b abut on the outer end surface of the projection 3 of the other mounting plate 1b and are incorporated into the square hole 5. The piece 6 and the elastic body 7 are retained.

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 piece 6 and the elastic body 7 from coming off, and is formed by the blind hole. The closed end of the square hole 5 may support both ends of the pin 9.

A projecting portion 10 having a rounded tip is provided on a surface of one of the mounting plates 1a of the piece 6 facing the projecting portion 2. On the other hand, the projecting portions 10 are provided on both end surfaces of the projecting portion 2. A plurality of engageable concave portions 11 are provided at regular intervals in the circumferential direction.

2 and 4, the radially extending projections are shown as the projections 10. However, as shown in FIG. 5, projections having hemispherical tips may be used as shown in FIG. The shape of the engaging recess 11 is determined according to the shape of the projecting portion 10. When the projecting portion 10 is a ridge, the engaging recess 11 is a groove extending in the radial direction. When the projection 10 is formed by a projection, the engagement recess 11 is a hole. It is sufficient that at least one protrusion 10 is provided.

In the hinge having the above structure, one of the pair of mounting plates 1a and 1b is mounted on an opening / closing member such as a lid or a door, and the other mounting plate is mounted on a fixed member supporting the opening / closing member.

Now, for example, one mounting plate 1a is mounted on the fixed member, and the other mounting plate 1b is mounted on the opening / closing member.
When the other mounting plate 1 b is rotated about the pin 9 by the rotation of the opening / closing member, the piece 6 incorporated in the square hole 5 of the projection 3 also rotates about 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 is moved by the elasticity of the elastic body 7 to the one mounting plate 1a.
And the protrusion 10 is engaged with the engagement recess 11. By this engagement, the other mounting plate 1b is prevented from rotating, and the opening / closing member mounted on the mounting plate 1b stops.

When the projection 10 and the engagement recess 11 are engaged with each other, the opening / closing member is pushed or pulled to push the other mounting plate 1b.
Is applied, the protrusion 10 is pushed by the opening edge of the engaging recess 11, the piece 6 is retracted against the elasticity of the elastic body 7, the protrusion 10 comes out of the engaging recess 11, and The mounting plate 1b rotates about the pin 9.

When the projection 10 faces the engagement recess 11,
In the same manner as described above, the piece 6 advances and the protrusion 10
1 and the other mounting plate 1b is prevented from rotating by the engagement.

As described above, when the projecting portion 10 faces the engaging concave portion 11, the piece 6 advances and the projecting portion 10
And the plurality of engaging recesses 11 are provided in the circumferential direction, so that the other mounting plate 1b can be stopped stepwise at each position where the protrusion 10 faces the engaging recess 11. The opening and closing member connected to the other mounting plate 1b can be stopped and held during opening and closing.

In the embodiment, one protrusion 2 is provided on one mounting plate 1a and two protrusions 3 are provided on the other mounting plate 1b, but the number of protrusions 2, 3 is not limited to this. Not something.

[0022]

As described above, in the present invention, when the pair of mounting plates are relatively rotated, the projecting portion engages with the engaging recess at a position where the projecting portion of the piece faces the engaging recess of the projecting portion. Since the pair of mounting plates are relatively prevented from rotating, the opening / closing member connected to one of the pair of mounting plates can be stopped and held during opening and closing.

Also, when the pair of mounting plates rotate, only the piece moves within the square hole due to the engagement and disengagement of the projection and the engaging recess, and the pair of mounting plates relatively move. , The opening and closing member attached to one of the mounting plates can be smoothly opened and closed, and the weight of the opening and closing member does not act on the contact portion between the piece and the projection, so that the contact portion has little wear and durability. Excellent hinges can be provided.

Further, the piece is inserted into a square hole formed in the projection.
Because it is stopped by entering, the detent of the piece
The mechanism does not appear to the outside, so you can get a nice hinge
And the opening of the square hole is closed by the facing projection.
As a result, the pieces cannot slide due to the intrusion of foreign matter
There is no inconvenience that the hinges always work well.
Can work.
