Abstract

Provided is a stand of a display device that can be reduced in its volume and allows a user to adjust a position of a display device more conveniently. The stand of a display device includes: a sliding unit for vertically moving a display device, the sliding unit mounted on the display device; a base unit for supporting the display device; and a hinge connection unit having a first end pivotally coupled to the sliding unit and a second end pivotally coupled to the base unit.

Claims

1. A stand of a display device comprising:

a sliding unit for vertically moving a display device, the sliding unit mounted on the display device;

a base unit for supporting the display device; and

a hinge connection unit having a first end pivotally coupled to the sliding unit and a second end pivotally coupled to the base unit.

2. The stand of a display device according to claim 1, wherein the sliding unit comprises:

a guide rail unit installed on the display device;

an elastic member having an end fixed inside the guide rail unit and expandable along the guide rail unit; and

a guide unit movable along the guide rail to expand and retract the elastic member.

3. The stand of a display device according to claim 2, wherein the guide unit slides along guide rails formed on the guide rail unit.

4. The stand of a display device according to claim 2, further comprising a supporting unit for allowing a portion of the guide unit to be supported on an upper end of the hinge connection unit.

5. The stand of a display device according to claim 4, wherein the supporting unit is hinge-coupled to the hinge connection unit.

6. The stand of a display device according to claim 2, wherein the guide rail unit and/or the guide unit is/are formed of plastic.

7. The stand of a display device according to claim 1, wherein the sliding unit comprises:

a guide rail unit formed in the vertical direction of the display device;

a guide unit slidably installed inside the guide rail unit; and

an elastic member for stopping the guide unit at a predetermined location of the guide rail unit.

8. The stand of a display device according to claim 1, wherein the hinge connection unit comprises:

a supporting unit coupled to the sliding unit and supporting the display device;

a link unit pivotally coupled between the base unit and the supporting unit;

a link hinge unit hinge-coupling the supporting unit to the link unit; and

a base hinge unit hinge-coupling the link unit to the base unit.

9. The stand of a display device according to claim 8, wherein the link unit comprises:

a main link having a first end pivotally connected to the supporting unit and a second end pivotally connected to the base unit;

an auxiliary link connected between the supporting unit and the base unit, the auxiliary link pivoting about a pivot center eccentric from a pivot center of the main link; and

an elastic member having first and second ends fixed on the main link and the auxiliary link, respectively.

10. The stand of a display device according to claim 8, wherein the elastic member having a fixed end and expanding in a direction when the main link pivots.

11. The stand of a display device according to claim 8, wherein the base hinge unit has a folding stopper, the folding stopper comprises:

a latch supported on the base unit not to rotate relative to the base unit when the link unit folds;

a rotational unit rotating relative to the hinge connection unit when the link unit folds; and

an elastic member biasing the latch and the rotational unit toward each other.

12. The stand of a display device according to claim 11, wherein the latch and the rotational unit contact each other.

13. The stand of a display device according to claim 11, wherein the latch is provided with a projection and the rotational unit is provided with a hook step corresponding to the projection.

14. The stand of a display device according to claim 13, wherein the rotational body is provided with a seating groove on which the projection seats when the hinge connection unit folds.

15. A stand of a display device comprising:

a sliding unit for vertically moving a display device, the sliding unit mounted on the display device;

a hinge connection unit pivotally coupled to the sliding unit and extending downward; and

a base unit pivotally coupled to the hinge connection unit and having an opened curve section.

16. The stand of a display device according to claim 15, wherein the base unit has a “

”

-shaped section.

17. The stand of a display device according to claim 15, wherein the hinge connection unit folds toward an opened portion of the base unit.

18. A stand of a display device comprising:

a sliding unit for vertically moving a display device, the sliding unit mounted on the display device;

a hinge connection unit pivotally coupled to the sliding unit and extending downward; and

a base unit pivotally coupled to the hinge connection unit and having a connecting portion connected to the hinge connection unit and legs extending from opposite ends of the connecting portion.

19. The display device according to claim 18, wherein the connecting portion and the legs are straight.

20. The display device according to claim 19, wherein the base unit has a “

”

-shaped section.
