Abstract

In order to provide a stand for a display monitor capable of preventing the occurrence of abnormal noise when the stand moves upward and downward and capable of being intended to be thinner in thickness by exercising ingenuity especially in a raising and lowering mechanism, the stand is composed of a base member attached to a pedestal portion; a case body erected on the base member; a raising and lowering plate inserted in the case body so that the plate can slide in upward and downward directions; a bracket to which a display monitor is attached, installed on an upper side of the raising and lowering plate via a tilt mechanism; a rack member attached to the raising and lowering plate; and a torque limiter having a driving pinion gear engaged with the rack member, which is fixed to the case body and generates a rotation torque when rotating in one direction.

Claims

1. A stand for a display monitor comprising:

a base member attached to a pedestal portion;

a case body erected on said base member;

a raising and lowering plate having slide members attached to both sides of the raising and lowering plate and inserted in said case body so that said plate can slide in upward and downward directions by said slide members;

a bracket to which a display monitor is attached, installed on an upper side of said raising and lowering plate via a tilt mechanism;

a rack member attached to said raising and lowering plate; and

a torque limiter having a driving pinion gear engaged with said rack member, which is fixed to said case body and generates a rotation torque when rotating in one direction;

wherein said raising and lowering plate having a guide hole is formed at a central part thereof vertically upward and downward, said rack member attached to one side portion of said guide hole, and one of said torque limiter and said driving pinion passed through said guide hole.

2. The stand for the display monitor according to claim 1, wherein said case body is swingably installed in front and back directions with respect to said member via the tilt mechanism.

3. The stand for the display monitor according to claim 1, wherein said bracket is attached to said raising and lowering plate via the tilt mechanism.

4. The stand for the display monitor according to claim 1 wherein one or both of said driving pinion gear and said rack member is/are made of synthetic resin.

5. The stand for the display monitor according to claim 1 to wherein said slide members constitute of each pair of members attached to said both side portions of said raising and lowering plate from front and rear direction.

6. The stand for the display monitor according to claim 1, wherein said case body having a stopper regulate a sliding motion of upward and downward direction of said raising and lowering plate by engaging with said guide hole.
