The present invention relates to a video display device, and more particularly, to a hinge assembly for a video display device for controlling the angle between the monitor body and the stand by rotatably connecting the stand with respect to the monitor body of the video display device.

In general, in order to use flat panel monitors such as liquid crystal display (LCD) monitors on the floor of a desk or a table, a stand for supporting the monitor is required. These stands are coupled to the rear of the monitor via a hinge assembly so that the user can adjust the monitor's tilt angle to a desired angle.

However, the hinge assembly of a conventional conventional monitor is configured such that the angle adjustment between the monitor and the stand can be made only within a certain angle range. Therefore, in the related art, there is a problem in that the user cannot adjust the angle between the monitor and the stand beyond a predetermined range, and this problem causes a user's dissatisfaction with the monitor angle adjustment.

For example, when the user places the monitor on a desk or table, the user may use a small angle range between the monitor and the stand. However, when the monitor stand is placed on a stand such as a stand or wall, which is separately manufactured, it is necessary to use the inclination angle of the monitor in a range larger than the normal angle range.

However, as described above, the conventional monitor cannot change the angle adjustment range between the monitor and the stand, and thus a problem that cannot be dealt with according to various situations occurs.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a hinge assembly for an image display device, which allows the user to selectively vary the angle adjustment range between the monitor body and the stand.

In order to achieve the above object, the present invention includes a fixing bracket fixed to the rear of the monitor body; A rotating shaft fixed to an upper portion of a stand supporting the monitor body and rotatably installed on the fixing bracket; A torque generating member for generating a predetermined torque on the rotating shaft with respect to the fixed bracket when the rotating shaft is rotated by a predetermined angle with respect to the fixed bracket; It provides a hinge assembly for an image display device comprising a rotation angle limiting device for varying the rotation angle adjustment range of the rotation axis so that the rotation of the rotation axis relative to the fixed bracket is selectively made within the first and second angle ranges. .

According to one embodiment of the invention, the rotation angle limiting device and the engaging portion formed to protrude radially on the outer surface of the rotating shaft; A rotation limiting part protruding into the movement path of the locking portion to limit the movement of the locking portion to the fixing bracket; It is characterized in that it is configured to include a rotation angle variable for limiting and releasing the movement of the locking portion while being selectively positioned inside and outside the movement path of the locking portion by an external force at a position spaced apart from the rotation limiting portion.

Hereinafter, a preferred embodiment of an image display hinge assembly according to the present invention that can specifically realize the above object will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the stand 2 is rotatably installed at the rear of the monitor main body 1 placed on the bottom surface via the hinge assembly 3. The stand 2 supports the monitor main body 1 with respect to the bottom surface while maintaining a predetermined angle with the monitor main body 1 by a predetermined torque generated in the hinge assembly 3.

2 and 3, the hinge assembly 3 has a fixing bracket 31 fixed to the rear of the monitor main body, one end of which is fixed to the upper end of the stand 2 and the other end of the fixing bracket. A pair of rotation shafts 32 rotatably provided at 31 are provided.

One end of each of the rotating shafts 32 is fixed to the fixing bracket 31 and the other end is fixed to the stand 2, and a torsion spring 34 that generates torque by the elastic force to the stand 2 with respect to the fixing bracket 31. ) Are respectively combined.

In addition, a pair of engaging pins 322 protrude in a radial direction to each of the rotation shafts 32 so as to face each other with a side portion of the fixing bracket 31 adjacent to each other. In addition, a rotation limiting the movement of the locking pin 322 is formed to protrude into the movement path of the locking pin 322 on both side portions of the fixing bracket 31.

In addition, as shown in Figures 3 and 4, the through hole 313 is formed in the center of the fixing bracket 31 in the vertical direction. The push bar 361 is installed through the through hole 313, and the push bar 361 is elastically supported by the compression spring 363 disposed in the through hole 313.                     

The upper portion of the push bar (361) is preferably formed to protrude to the outside of the upper portion of the fixing bracket 31 so that the user can be pushed from the outside.

In addition, a stopper 362 is connected to the lower end of the push bar 361. The stopper 362 is accommodated in the receiving groove 314 formed in the left and right directions at the bottom of the fixing bracket 31, so that both ends protrude outwards both sides of the fixing bracket 31, that is, of the locking pin 322 It is installed to be located inside the movement path.

The operation of the embodiment of the hinge assembly 3 described above is as follows.

FIG. 5A shows a state where the monitor main body 1 and the stand 2 are angle-adjusted within the first angle range θ1 by the hinge assembly 3. As shown in FIG. 5A, the locking pins 322 located at the lower side of the locking pins 322 of the rotating shaft 32 are supported by the front of the stopper 362 and the movement thereof is restricted. ) And the stand 2 is the maximum.

When the rotating shaft 32 rotates in the opposite direction, the upper locking pin 322 is caught by the rotation limiting portion 312 of the fixing bracket 31 and the movement is restricted. At this time, the monitor main body 1 and the stand are supported. The angle between (2) is minimum.

In the state where the angle between the monitor main body 1 and the stand 2 is adjusted within the first angle range θ1, the monitor main body 1 is applied to a torque provided by the elastic force of the torsion springs 34. As a result, the angle of the stand 2 is maintained on the bottom surface.

Then, when the user wants to vary the tilt angle adjustment range of the monitor, as shown in FIG. 5B, when the user presses the upper end of the push bar 361 exposed to the upper part of the fixing bracket 31, the push bar 361 together with the push bar 361. Stopper 362 is lowered.

Accordingly, the stopper 362 is moved out of the movement path of the locking pin 322, and the one-way movement of the locking pin 322 in the lower portion is free. In this state, when the user pivots the stand 2 backward, the locking pin 322 of the lower part moves to the rear position of the stopper 362 while rotating in the counterclockwise direction on the drawing of the rotation shaft 32.

When the engaging pin 322 is completely moved to the rear position of the stopper 362, as shown in Figure 5c, the user removes the force to push the push bar (361). At this time, the push bar 361 is returned to the original position by the elastic force of the compression spring 363, the stopper 362 is moved back to the receiving groove 314, the both ends of the movement of the locking pin 322 It will be relocated within the path.

Therefore, since the locking pin 322 of the lower portion of the rotating shaft 32 can be rotated between the rotation limiting portion 312 and the stopper 362, in this state, the monitor main body 1 and the stand 2 are removed. Angle adjustment is made within the two angle range θ2.

When the user wants to return the angle adjustment range between the monitor main body 1 and the stand 2 to the first angle range θ1, the push pin 361 is pushed to the stopper 362 by pressing the push bar 361 as described above. By moving forward to make a state as shown in Figure 5a is simply the angular range variable is made.

The effect of the hinge assembly for an image display device according to the present invention as described above is as follows.

According to the present invention, since the user can use the angle adjustment range between the monitor main body and the stand very simply, the user can satisfy various angle adjustment needs.
