Description

Hinge device

The present invention relates to a hinge device, and more particularly, to a hinge device having an improved structure to generate reliable anti-torque and to give an accurate rotation angle.

In general, the hinge device is installed at one end of the first body part and the second body part, and when the torque is applied to the other end of the specific body part from the outside, the hinge device generates anti-torque. Thus, the torque in one direction applied to the other end of the specific body portion rotates the specific body portion in one direction while overcoming the anti-torque. When the torque in one direction is removed from the other end of the specific body part, the self-weight torque generated due to the specific weight of the specific body part and the anti-torque generated in the hinge device make torque equilibrium. The torque in one direction is maintained at the position where it was removed.

Referring to FIG. 1, the hinge device includes a housing 110 installed in a first body (not shown), an adapter 120 installed in a second body (not shown), and the housing 110 and the adapter ( A constant anti-torque is generated at 120 and includes a torque generating unit 130 to connect rotatably. The housing 110 is provided with a frame 115 at one end of the column 113 and a frame hole (not shown) at the other end of the frame 115. In addition, the adapter 120 has one or more base holes 125a and 125b installed in the base 123, and a connection part 127 connected to the torque generator 130 at one end of the base 123. ) Is installed. In the torque generating unit 130, the frame hole (not shown) is inserted into the shaft 133. In addition, a plurality of washers 135 generating torque by friction with the frame 115 is inserted into one side of the frame hole (not shown), and the frame 115 is provided at the other end of the washer 135. A nut 137 is installed to compress and fix the friction between the washer 135 and the washer 135.

Referring to the operation of the hinge device configured as described above are as follows.

When the torque in the first direction (shown in FIG. 1) is applied to the other end of the second body (not shown) in which the adapter 120 is installed, the adapter 120 installed in the second body (not shown) is moved in the first direction ( Rotated (shown in FIG. 1). The shaft 133 attached to the adapter 120 overcomes the anti-torque generated by friction between the washer 135 and the frame 115 in the second direction (shown in FIG. 1). Rotate in the first direction (shown in FIG. 1). In this case, when the torque in the first direction (shown in FIG. 1) given to the other end of the second body (not shown) is removed, the second body (not shown) may have a weight of the second body (not shown). Self-torque torque generated by the torque and the anti-torque generated by the friction of the washer 135 and the frame 115 to form a torque equilibrium, the state at the moment of removing the torque in the first direction (shown in Figure 1) Will be maintained. In addition, when the torque in the second direction (shown in FIG. 1) is applied to the other end of the second body (not shown) in which the adapter 120 is installed, the adapter 120 installed in the second body (not shown). Is rotated in the second direction (shown in FIG. 1) by the above principle. In this case, when the torque in the second direction (shown in FIG. 1) given to the other end of the second body (not shown) is removed, the second body (not shown) may be caused by the weight of the second body (not shown). The self-torque torque generated and the anti-torque generated by the friction between the washer 135 and the frame 115 form torque equilibrium to remove the torque in the second direction (shown in FIG. 1). Will be maintained.

In the conventional hinge device configured as described above, the contact area between the washer 135 and the frame 115 is small and the reliability of generating a predetermined amount or more of anti-torque is low. In addition, since the end of the housing 110 connected with the shaft 133 is bent and protrudes, a certain amount of the bent end of the housing 110 is bent by a given torque, and the housing is removed when the torque is removed. Since the bent portion of the bent end of 110 is restored to its original state, it is difficult to give an accurate rotation angle to the second body.

The present invention is devised to solve the above problems, and an object thereof is to provide a hinge device capable of generating reliable anti-torque and giving an accurate rotation angle to the body to be rotated.
