Abstract

Hinge assembly including a horizontal shaft, a monitor rotator having one part fixed to the shaft for rotating as one unit with the shaft, and the other part fixed to a rear part of the monitor, supporting member rotators rotatably coupled to opposite sides of the shaft, a supporting member fixed to the supporting member rotators for supporting the monitor at a rear part thereof from a floor at an angle to the monitor, and elastic members provided to the shaft such that one end thereof is held at the monitor rotator fixed to the monitor, and the other end thereof is held at the supporting member rotators fixed to the supporting member, for providing an appropriate torque between the monitor and the supporting member according to an angle between the monitor and the floor, thereby adjusting a tilting angle of the LCD monitor.

Claims

1. A hinge assembly comprising:

a horizontal shaft;

a monitor rotator having one part fixed to the shaft for rotating as one unit with the shaft, and the other part fixed to a rear part of the monitor;

supporting member rotators rotatably coupled to opposite sides of the shaft;

a supporting member fixed to the supporting member rotators for supporting the monitor at a rear part thereof from a floor at an angle to the monitor; and

,

elastic members provided to the shaft such that one end thereof is held at the monitor rotator fixed to the monitor, and the other end thereof is held at the supporting member rotators fixed to the supporting member, for providing an appropriate torque between the monitor and the supporting member according to an angle between the monitor and the floor.

2. A hinge assembly as claimed in claim 1, wherein the elastic members are a plurality of torsion springs coupled on opposite sides of the shaft.

3. A hinge assembly as claimed in claim 1, wherein the monitor rotator includes;

a horizontal part having fastening holes for screw fastening to a rear part of the monitor,

a fastening part extended from a central part of the horizontal part toward the shaft having screw holes for screw fastening with a central part of the shaft, and

holding holes adjacent to comers between the horizontal part and the fastening part for holding ends of the elastic members.

4. A hinge assembly as claimed in claim 1, wherein each of the supporting member rotators includes;

a vertical leaf having fastening holes for screw fastening to the supporting member, and

a coupling leaf of a disk form formed as a unit with the vertical leaf having a central hole for inserting to the shaft.

5. A hinge assembly as claimed in claim 4, wherein the coupling leaf of the supporting member rotator includes;

a limiting slot formed as a portion of an outer circumference of the disk is cut away dispose a part of the supporting member rotator therein, for limiting a rotation angle of the supporting member rotator by a length of the limiting slot.

6. A hinge assembly as claimed in claim 1, wherein the shaft includes;

screw holes in a central part for fastening the monitor rotator thereto, and

guide walls at opposite sides of the central part for alignment with the monitor rotator, for being pressed by the elastic members to cause friction when the shaft rotates.

7. A hinge assembly as claimed in claim 1, further comprising;

friction washers inserted in opposite ends of the shaft in contact with the supporting member rotators, and

nuts on outer sides of the friction washers for pressing the friction washer against the supporting member rotators.
