Patent ID: 8106278

Claim:
An adjustable support apparatus comprising: a ball having a passage therethrough, an item support rack member having a longitudinal axis and established through said passage; a housing that itself comprises ball compression surfaces adapted to apply a ball retention force to said ball, wherein said ball retention force, when applied to said ball, immobilizes said ball relative to said housing; wherein disapplication of said ball retention force causes said apparatus to be in a rack member release configuration, and when said apparatus is in said rack member release configuration said ball may be slidably moved relative to said item support rack member, along said longitudinal axis; item support arm compression surfaces adapted to apply an item support arm retention force to an item support arm; a ball retention force enhancer adapted to enhance said ball retention force without enhancing said item support arm retention force; and an item support arm retention force enhancer adapted to enhance said item support arm retention force without enhancing said ball retention force, wherein said ball is adapted to be side-assemblable onto said item support rack member, wherein said housing moves through space during said longitudinal axial motion of said ball relative to said item support rack member when said apparatus is simultaneously in: said rack member release configuration, and a item support arm lock configuration.
