DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge used for a rotating mechanism such as a door, and more particularly to a hinge capable of arbitrarily setting a rotation stopping angle.

[0002]

2. Description of the Related Art Doors are provided in various relatively large electronic devices and the like. In particular, in maintenance and inspection of the devices, the door may be obstructed by opening too much. There has been a demand for a rotation stop mechanism that does not open beyond an angle. Heretofore, hinges used for a rotation mechanism such as a door have conventionally been constituted only by a combination of a columnar base, a shaft erected at the center of the columnar base, and a cylindrical body into which the shaft is loosely fitted. In the hinge having such a configuration, it is impossible to stop the rotation because of its structure. Therefore, in the rotation mechanism such as the door, the rotation is stopped by a part or mechanism other than the hinge.

[0003]

However, when the rotation is stopped by fixtures and mechanisms other than hinges, processing and mounting of the parts and mechanisms are required separately, which is troublesome and costly. In addition, there is a problem that components and mechanisms become complicated and large. Further, there is a problem that a desired arbitrary rotation stop angle cannot be set depending on these parts, mechanisms, and the like.

The present invention has been proposed in order to solve such problems of the prior art, and has a simple structure in which an arbitrary detent angle can be set and changed by the hinge itself. The purpose is to provide.

[0005]

In order to achieve the above object, according to the present invention, there is provided a hinge used for a rotating mechanism such as a door, wherein a shaft erected at the center of a columnar base is provided. A cylindrical body with which the shaft is rotatably engaged, and a ring-shaped fitting loosely fitted to the shaft and interposed between the cylindrical body and the cylindrical body;
Radial grooves around the shaft on the shaft side rotating contact surface
And forming one of the metal fittings on the rotating contact surface.
Forming a radial groove that meshes with the radial groove of the substrate,
One, their substantially the same circumferential contact surfaces of the cylinder and fitting
Each has a configuration in which a stopper is formed. Further, the present invention according to claim 2 is a hinge used for a rotation mechanism such as a door, wherein a shaft erected at the center of a columnar base body;
A cylindrical body which the shaft is engaged rotatably consists of a interposed by a ring-shaped fitting between loosely fitted on the shaft of the cylindrical body and the cylindrical body, one side rolling contact of the cylindrical body surface
A radial groove on the other side of the bracket.
A radial groove that meshes with the radial groove of the cylindrical body on the rolling contact surface
And a stop portion is formed on the surface of the cylindrical base and the metal fitting in contact with each other in substantially the same circumference.

[0006]

According to the above-described structure, the position of the stop portion of the fitting can be set to an arbitrary position by changing the position at which the groove formed in the fitting is engaged with the columnar base or cylindrical body. The stop portion of the metal fitting and the stop portion of the columnar base or the cylinder come into contact with each other so that the rotation angle of the hinge is set to an arbitrary angle.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a variable rotation angle hinge according to the present invention. FIG. 1 is a perspective view showing a first embodiment of the variable rotation angle hinge. In FIG. 1, reference numeral 1 denotes a columnar base, which is integrally fixed to a side portion of the first hinge piece 2 and a columnar shaft 4 is provided upright at the center. Grooves 3 are provided radially around the shaft 4 on the shaft-side rotational contact surface of the cylindrical base 1. Reference numeral 5 denotes a thin ring-shaped metal fitting that is loosely fitted to the shaft 4, and a radial groove 6 that meshes with the groove 3 of the cylindrical base 1 is formed on one of the rotating contact surfaces.
On the other rotating contact surface, a stop portion 5 is provided on the circumference thereof. Reference numeral 8 denotes a cylindrical body, which has a cylindrical shape having a hollow portion with which the shaft 4 is rotatably engaged, and is integrally fixed to a side portion of the second hinge piece 9. A stop 10 is provided on the rotation contact surface of the cylinder 8 so as to abut the stop 7 of the metal fitting 5 on the circumference thereof.

The variable rotation angle hinge having such a configuration is used as follows. That is, first, the first hinge piece 2 is fixed to the chassis or the like of the rotation mechanism of the apparatus main body to which the door or the like is attached by screwing or the like. On the other hand, the second hinge piece 9 is fixed by screwing the door or the like. Next, the metal fitting 5 is inserted into the groove 6 on the shaft 4 erected on the cylindrical base 1.
Is loosely fitted toward the cylindrical base 1 side. Next, the groove 6 of the metal fitting 5 is engaged with the groove 3 of the cylindrical base 1 so that the stopper 7 is located at an arbitrary position. Further, the cylinder 8 fixed to the door or the like by the second hinge piece 9 is engaged with the shaft 4. As a result, the second hinge piece 9 rotates about the shaft 4 as an axis, and the cylindrical body 8
When the stop 10 of the second hinge piece contacts the stop 7 of the metal fitting 5, the rotation of the second hinge piece stops. As a result, the door or the like to which the second hinge piece 9 is fixed stops opening at a certain angle. Therefore, by changing the position where the groove 6 of the metal fitting 5 meshes with the groove 3 of the cylindrical base body 1 and changing the position of the stop portion 7, the opening angle of the door or the like, that is, the rotation stop angle of the hinge is arbitrarily set. , Can be changed.

FIG. 2 is a perspective view showing a second embodiment of the variable rotation angle variable hinge. In this embodiment, to form a stop portion 10,7 substantially the same circumferential contact surfaces of the cylindrical body 1 and the bracket 5, one side rolling contact surface of the cylindrical body 8 <br/> and fitting 5 And radial grooves 3 and 6 are formed on the other rotating contact surface .

[0010] The present invention is not limited to the above embodiment, but includes various modifications within the scope of the gist. For example, the grooves 3 and 6 in which the columnar base 1 and the metal fitting 5 are engaged are not limited to the grooves, but may be any engaging means that can be changed in several ways. It is also possible to provide a scale or the like as shown. Further, the variable rotation angle hinge according to the present invention is not limited to a door or the like, and can be used for any hinge whose opening angle is to be limited using a hinge.

[0011]

As described above, according to the present invention,
With a simple structure, an arbitrary rotation stop angle can be easily set and changed by the hinge itself.
