If described in detail for better understanding, the basic structure is a free-stop torque that changes the angle only when a certain force or more is applied to the basic hinge structure in which the TV 100 rotates due to the rotation of the rotating shaft 41. A tilt spring 43 was used as a structure for implementation.

That is, when the nut 46 is tightened, the tilt spring 43 exerts a compressive force to press the shaft fixing part 422 so that the inclination changes only when a certain force or more is applied, and the free stop torque is adjusted even during use. To do this, simply remove the cover 49 and tighten or loosen the nut 46 .

At this time, several disk washers 45 are mounted to prevent the nut 46 from loosening, and the bush 44 serves to prevent abrasion between the rotating shaft 41 and the stand frame 42 . .

In addition, in order to prevent loosening of the nut in an additional, more aggressive way, at least two or more surfaces are in close contact with the inside of the stand frame 42 between the disk washer 45 and the both sides of the abrasion-preventing bush 44 and the nut 46 . It shows an embodiment in which the guide bracket 451 to prevent rotation is additionally formed.

In addition, as shown in FIG. 4 , the tilting ends 431 and 432 of the tilt spring 43 rotate the stand frame 42 counterclockwise, the tilting end 432 is the inner wall surface of the first stand 47 . It is in close contact with the to prevent further rotation, and to prevent the other tilting end 431 from rotating in close contact with the clockwise rotation.

At this time, even if it is prevented from rotating due to the characteristics of the tilt spring 43, it is possible to prevent damage to the product due to an excessive impact due to the elastic restoring force acting after the rotation is further caused by a strong force.

In the embodiment of limiting the angle, when the slope is changed in the upward direction, it is not so large that it is a preferable example to limit about 5° to about 20° in the downward direction.

7A to 7D are conceptual views illustrating a change in left and right inclination according to an embodiment of the present invention. The hinge portion connecting the first link bracket 2 and the second link bracket 3 is the hinge shaft 21 A stopper 31 protruding from any one of the first link bracket 2 and the second link bracket 3 is formed around it, and the stopper 31 is inserted into the other one of the jaws 22 to prevent further rotation. ) is formed so that the left and right inclination changes are not made by more than a certain angle is shown.

When described with reference to the drawings, when the first link bracket 2 and the second link bracket 3 on the left and right are symmetrically mounted, when the jaw 22 and the stopper 31 are formed, a certain amount is formed at the hinge connection part of one side. Rotation is limited by more than an angle, and the maximum left-right inclination is determined.

At this time, in the drawings, the rotation is limited at the connection part of the first link bracket 2 and the second link bracket 3, the angle of which is widened as much as possible. This will be able to facilitate the chin 22 and the stopper 31 in the present application can be said to have the same structure.

According to this embodiment, the user can freely adjust the TV 100 in a state in close contact with the wall, in a state spaced apart from the wall, and in a state inclined in a certain direction.

In addition, in the present invention, plate-shaped first and second reinforcing guides 23 and 32 (refer to FIG. 2 ) connecting the ends at which both hinges are formed are overlapped on the first link bracket 2 and the second link bracket 3 . A fixed example is further presented.

In the above embodiment, the first and second reinforcing guides 23 and 32 are overlapped and mounted to maximally prevent damage to the device due to an excessive impact as the load of the TV 100 acts vertically.
