US Patent 7523907 Hanger for electronic apparatus

A hanger for an electronic apparatus. The hanger comprises a base mounted to a wall, a bracket pivoting on the base, a first link pivoting on the base and comprising a ratchet with a plurality of teeth, and a second link with a stopper rotatably connecting the first link and the bracket. The angle between the bracket and the base is varied by the stopper engaging each tooth of the ratchet. The bracket can rotate between a first position and a second position. When the bracket is in the first position, the bracket overlaps the base, and in the second position, the angle between the bracket and the base is maximized.
