US Patent 7861992 Wall-mount support

A wall-mount support includes: a wall bracket adapted to be mounted on a wall and having a vertical track; a carrier mounted slidably on the vertical track; a pair of supporting arms, each of which extends from the carrier in a transverse direction relative to the vertical track and each of which is pivoted to the carrier so as to permit angle adjustment therebetween; and a brake mechanism including a friction-providing member connected to the carrier and operable to abut against the vertical track so as to prevent sliding movement of the carrier on the vertical track.
