Patent ID: 7928304

Claim:
A support apparatus comprising: two item support rails, each partially supported by a shared rail support leg to which each of said two item support rails is coupled by a different pivot coupler, two additional rail support legs, each partially supporting a different one of said two item support rails, wherein each of said rail support legs has a lower end adapted to rest on a lower supporting surface, wherein each of said pivot couplers pivotally couples only one of said item support rails to said shared rail support leg, said shared rail support leg defining a substantially vertical axis, wherein one of said pivot couplers is established at an upper site on said shared rail support leg that is above a lower site on said shared rail support leg at which the other of said pivot couplers is established, wherein said each of said pivot couplers comprises separable, first and second compression elements compressed towards each other in an oppositely facing orientation with at least one compression enhancement element, and around a rail terminus of said one of said item support rails and a portion of said shared rail support leg, wherein said each of said pivot couplers enables rotatable motion of the item support rail that it couples, independently about said substantially vertical axis, wherein said each of said pivot couplers enables independent, substantially purely vertical translatory height adjustment of a different one of said item support rails relative to said shared rail support leg, wherein said rail terminus defines a rail terminus interface, and wherein said each of said pivot couplers establishes at least one cable port and a cable channel that directs a cable from travel in a first direction internally through the item support rails it couples and along a rail axis defined thereby, to travel through at least a portion of said cable channel in a second, different direction and out through a cable port, wherein said second, different direction is substantially parallel with said substantially vertical axis defined by said shared rail support leg.
