TECHNICAL FIELD The present invention relates to a hinge device, and more particularly, to a hinge device used for a mechanism requiring a different rotation torque in accordance with the rotation direction.

In general, the hinge device coupled to the door or the cover to facilitate the opening or closing action of the door or the cover does not have a function of adjusting the rotational force according to the direction of rotation. Thus, a hinge device that can not adjust the rotational force in accordance with the rotation direction, for example, a position adjusting hinge device having a ball or embossing to enter and exit the groove formed at a predetermined interval to position the door at a set position When the door is open upward, the same force acts on the hinge device when the door is opened or closed, but when the door is opened, the weight of the door is added so that the door is not easy to open.

In addition, the hinge device used in various technical fields may use a one-way clutch 1 as shown in FIG. 1, which is coupled to the shaft 3 to the shaft 3 or the clutch body. It is to rotate (5) in one direction. That is, the one-way clutch 1 includes a hollow clutch body 5 and the groove having a groove 8 and a protrusion 7 formed around the shaft 3 and alternately formed at predetermined intervals on the inner circumferential surface thereof. It is provided with a spherical contact member 9 inserted in the space formed between the 8 and the projection 7, and acting in the space such that the shaft 3 or the clutch body 5 is rotated in one direction. This is because when the shaft 3 rotates clockwise as shown, the contact member 9 climbs up the inclined portion 7a of the projection 7 and is inserted into the recess 8. At this time, the contact member 9 is not in contact with the shaft 3, the shaft 3 can rotate, and when the shaft 3 rotates counterclockwise, the contact member 9 is the shaft 3 and the clutch While contacting the body (5) is caught in the curved portion (7b) of the projection (7) it is impossible to rotate the shaft (3). Of course, when a force greater than the frictional force generated by the contact of the contact member 9 and the shaft 3 is applied to the shaft 3 or the clutch body 5, it is rotatable counterclockwise.

Therefore, when the clutch 1 is used in a predetermined hinge device, only the one-way rotation function can be performed, and the rotational force control is difficult. That is, when the clutch body 5 is integrated with the rotating body 11 such as a door or a cover and the shaft 3 is fixed to the fixed support 13 (FIG. 2 (a), (b)), upwards When a force is applied to the rotating body 11, the clutch 1 is operated to stop the rotating body 11, and when a force is applied to the rotating body 11 downward, the clutch 1 is not operated, so the shaft 3 Rotating body 11 can be rotated around. Then, the member is rotated even when the clutch body 5 is integrally fixed to the fixed support body 15 and the shaft 3 is integrally coupled to the rotating body 17 (FIG. 3 (a) and (b)). This is the same as in the case of FIG.

The present invention was created in order to solve the problems as described above, it is possible to control the bidirectional rotation by using a conventional one-way clutch, the operating force in accordance with the rotational direction of the rotating body during the rotation of the rotating body such as a door or cover It is an object of the present invention to provide a hinge device that facilitates the operation of the rotating body by being different.
