Patent ID: 7404234

Claim:
A hinge structure for a display device, comprising: a fixed plate having a main body portion configured to be mounted on a support and first and second arms that extend from the main body portion; a rotation shaft that passes through the first and second arms of the fixed plate; first and second pivotal plates configured to be attached to a display, wherein the first and second pivotal plates are fixed to first and second ends of the rotation shaft such that the pivotal plates rotate with the rotation shaft relative to the fixed plate; and a braking unit which is mounted on the fixed plate, wherein the braking unit is configured to apply a frictional force to the rotation shaft to limit rotation of the rotation shaft relative to the fixed plate, and wherein the braking unit comprises: a braking member that includes two tightening plates joined by a substantially cylindrical friction portion which surrounds an outer circumference of the rotation shaft and which is configured to apply friction to the rotation shaft to limit movement of the rotation shaft; a leaf spring interposed between the tightening plates; and a fastener configured to adjust a spacing between the tightening plates, to thereby vary an amount of friction applied to the rotation shaft by the braking member.
