ABSTRACT:
A height-adjustable support includes a stand unit, a friction-providing assembly including a stationary member disposed stationarily on the stand unit and a movable member movable relative to and in frictional contact with the stationary member, a link assembly coupled to the movable member such that pivoting movement of the link assembly results in movement of the movable member relative to the stationary member, a mounting seat disposed on a distal end portion of the link assembly and adapted to support a load, and a biasing assembly coupled to the movable member and to the stand unit. A biasing force exerted by the biasing assembly on the movable member and a frictional force generated between the stationary member and the movable member cooperate to balance the weight of the load and position the link assembly to sustain the load at an arbitrary height.
