Patent ID: 7874530

Claim:
A supporter usable with a display apparatus, comprising: a base; a vertical moving member coupled to a display main body; a guide frame coupled to the base to support the vertical moving member to slide up and down with respect to the base; a spring rotor supported in the vertical moving member to rotate about a rotational axis transverse to a moving direction of the vertical moving member and to move up and down along with the vertical moving member with respect to the base; a spiral plate spring comprising an inside end part coupled to the spring rotor, a middle part wound around the spring rotor, and an outside end part coupled to the guide frame to elastically resist a downward movement of the vertical moving member; a spring friction part to frictionally contact the spiral plate spring to resist a rotational movement of the spiral plate spring; and a rotor friction part to frictionally contact the spring rotor to resist a rotational movement of the spring rotor.
