Abstract

PURPOSE:To set or change an optional rotary motion-stop angle with a hinge itself based on a simple structure. CONSTITUTION:This hinge comprises a shaft 4 installed vertically to the center of a cylinder-shaped base body 1 and a cylinder 8 with which this shaft 4 is engaged rotatively and a ring-shaped metal fitting 5 installed between the cylinder-shaped base body 1 freely fitted into the shaft 4 and the cylinder 8. Each of radial grooves 3 and 6 is formed on the surfaces in contact with the cylinder-shaped base body 1 and the metal fitting 5 while stoppers 7 and 10 are formed substantially on the same circumference whose surface is contact with the cylinder 8 and the metal fitting 5.

Description

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 whose rotation stopping angle can be arbitrarily set.

[0002]

2. Description of the Related Art Various relatively large electronic devices are provided with a door. However, when the device is maintained or inspected, opening the door too much can be a hindrance. There has been a demand for a rotation stop mechanism that does not open beyond an angle. By the way, conventionally, a hinge used for a rotating mechanism such as a door is constituted only by a combination of a columnar base body, a shaft erected at the center of the columnar base body, and a tubular body in which the shaft is loosely fitted. In the hinge having such a structure, it is impossible to stop rotation due to its structure. Therefore, in a rotating mechanism such as a door, the rotation is stopped by a part or mechanism other than the hinge.

[0003]

However, in the case where the rotation stop is performed by the equipment, mechanism, or the like other than the hinge, it is necessary to separately process and attach the parts, mechanism, etc., which is troublesome and costly. There is also a problem that parts, mechanisms, etc. are complicated and large. Further, there is also a problem that a desired arbitrary rotation stopping angle cannot be set depending on these parts and mechanisms.

The present invention has been proposed in order to solve the problems of the prior art, and has a simple structure that allows the hinge to set and change an arbitrary rotation stopping angle by the hinge itself. For the purpose of providing.

[0005]

In order to achieve this object, the present invention according to claim 1 is a hinge used in a rotating mechanism such as a door, and a shaft erected at the center of a cylindrical base body, The shaft is rotatably engaged with a cylindrical body, and the cylindrical base body is loosely fitted to the shaft and is interposed between the cylindrical base body and the cylindrical body. Radial grooves are respectively formed on the contacting surfaces, and the stoppers are formed on the contacting surfaces of the tubular body and the metal fittings on substantially the same circumference. Further, according to the present invention of claim 2, in a hinge used for a rotating mechanism such as a door, a shaft erected at the center of a cylindrical base body, a tubular body with which the shaft is rotatably engaged, and It consists of a cylindrical base body that is loosely fitted to the shaft and a ring-shaped metal fitting that is interposed between the cylindrical body, and a stopper is formed on the contact surface of the cylindrical base body and the metal fitting in substantially the same circumferential shape. Along with
A radial groove is formed on each of the surfaces of the cylindrical body and the metal fitting that come into contact with each other.

[0006]

According to the above construction, the position of the metal fitting stop portion can be set to an arbitrary position by changing the position at which the cylindrical base body or cylinder and the groove formed in the metal fitting are engaged with each other. The stopper of the metal fitting and the stopper of the cylindrical base body or the cylinder contact each other to set the rotation angle of the hinge to an arbitrary angle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a rotation stop angle variable hinge according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing a first embodiment of this rotation stop angle variable hinge. In the figure, reference numeral 1 is a columnar base, which is integrally fixed to a side portion of the first hinge piece 2, and a cylindrical shaft 4 is provided upright in the center. Grooves 3 are radially provided around the shaft 4 on the rotating 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. A radial groove 6 that meshes with the groove 3 of the cylindrical base 1 is formed on one rotating contact surface, and a rotating groove 6 is formed on the other rotating contact surface. Stops 5 are respectively provided on the circumference. Reference numeral 8 denotes a tubular 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 stopper 10 is provided on the circumference of the rotating contact surface of the cylindrical body 8 so as to abut the stopper 7 of the metal fitting 5.

The rotation stop angle variable hinge having such a structure is used as follows. That is, first, the first hinge piece 2 is fixed to the chassis or the like of the rotating mechanism of the apparatus 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 a door or the like. Next, the metal fitting 5 is provided in the groove 6 on the shaft 4 provided upright on the cylindrical base body 1.
The rotary contact surface provided with is fitted loosely toward the columnar base 1 side. Then, the groove 6 of the metal fitting 5 is engaged with the groove 3 of the columnar base 1 so that the stopper 7 is located at an arbitrary position. Further, the cylindrical body 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 and the cylindrical body 8
When the stopper portion 10 of the second contact piece comes into contact with the stopper portion 7 of the metal fitting 5, the rotation of the second hinge piece stops. As a result, the opening of the door or the like to which the second hinge piece 9 is fixed stops at a constant angle. Therefore, the opening angle of the door or the like, that is, the rotation stopping angle of the hinge is arbitrarily set by changing the position where the groove 6 of the metal fitting 5 and the groove 3 of the columnar base 1 are engaged with each other and changing the position of the stopper portion 7. ， Can be changed.

FIG. 2 is a perspective view showing a second embodiment of the hinge for varying the rotation stopping angle. In this embodiment, the stoppers 10 and 7 are formed on the surfaces of the columnar base 1 and the metal fitting 5 in contact with each other in substantially the same circumference, and the radial grooves 3 and 3 are formed in the surface of the cylindrical body 8 and the metal fitting 5 in contact with each other. 6 are formed respectively.

The present invention is not limited to the above embodiments, but includes various modifications within the scope of the gist. For example, the grooves 3 and 6 in which the cylindrical base body 1 and the metal fitting 5 mesh are not limited to grooves, but may be any meshing 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-stop angle hinge of the present invention can be used not only for doors and the like, but also for hinges whose hinges are used to limit the opening angle.

[0011]

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