Hinge structure for flat visual display device
First Claim
1. A hinge structure for a flat visual display device, comprising:
- a plurality of pivotal plates connected to the flat visual display device, for rotation of the flat visual display device;
a fixing plate connected to a supporting portion that supports the flat visual display device;
a rotational shaft inserted into vertical planes of the plurality of pivotal plates and the fixing plate, for rotation of the plurality of pivotal plates in one degree of freedom;
a frictional member mounted around an outer periphery of the rotational shaft, so as to enclose the rotational shaft, both ends of which have a frictional member tightening plane of a planar shape in which an inserting hole is formed;
a tightening member inserted into the inserting hole, so as to tighten the frictional member tightening plane, thereby tightening the rotational shaft by means of the frictional member, and generating strong breaking force accordingly; and
a plate shaped spacer inserted between the frictional member tightening planes, so as to provide a predetermined gap between the lightening planes, wherein one of the plurality of pivotal plates is provided on one side of the frictional member and another of the plurality of pivotal plates is provided on the other side of the frictional member.
