Abstract

PURPOSE:To make the turning angle of a hinge member on one side yet larger than that of a hinge member on the other by properly altering the number of teeth formed on a circular surface of each engaging part in these two hinge members. CONSTITUTION:With the rotation of a connecting member 30, a second hinge member 20 being pivoted to this connecting member is shifted along a circular surfaces 12b' of a first hinge member 10, while it is turned round as centering on a shaft 50 or a pivoting position by engagement between both engaging teeth 13 and 21b attendant upon this shifting. The number of teeth in both these engaging ones are properly altered, whereby the second member 20 is turned round, centering on a shaft projecting part 21d. with a yet larger angle as compared with the turning angle of the connecting member 30 with a shaft projecting part 14 of the first hinge member 10 as the center, or it is rotatable with a yet smaller angle otherwise. In addition, a setting angle of a movable body B to an engaging part 21 of the second hinge member 20 at a rotation ending position of the connecting member 30 is properly altered, whereby diversified rotations are thus realizable.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge structure used for rotatably mounting a movable body such as a door with respect to a main body.

[0002]

2. Description of the Related Art At present, various hinge structures are used for rotatably supporting a movable body such as a door with respect to a main body having an opening or the like closed by the movable body. The most common type of such a hinge structure is that a first hinge member that is assembled to the main body and a second hinge member that is attached to the movable body are attached to the shaft hole of the "spindle" that is provided on both members. Insert a shaft such as "No.
It is a pivotal structure.

[0003]

However, in the conventional hinge structure, since the two hinge members are connected by a single shaft, the movable body simply rotates about the shaft. Further, in the conventional hinge structure, when the opening angle or the closing angle of the movable body pivotally supported by the hinge structure with respect to the main body is to be adjusted to an appropriate angle, both members are provided. It was necessary to change the shape of the “top” provided and the “abutment” in the main body and the movable body to be connected. further,
Since the weight of the movable body rotated is added only to the shaft,
When the movable body has a considerable weight, it is necessary to give the shaft and the shaft hole portion a required strength.

Therefore, according to the present invention, it is possible to give various kinds of rotations to the movable body pivotally supported with respect to the main body, and to appropriately change the opening angle of the movable body with respect to the main body. It is an object of the present invention to provide a hinge structure that can be easily carried out and that has a structure in which the weight of a movable body is not applied only to the pivotal / coupling shafts of the hinge members forming the hinge structure.
