Abstract
Abstract The present invention is a shelving system having height adjustable shelves. The shelving system includes a plurality of elongated support posts having recesses spaced along the longitudinal axis. At least one resilient support post clip is attached to each support post within a recess to provide a shelf support. A shelf member having recesses at least partially accepting the post clip, is positioned in detachable nesting relationship with the support clips. The shelf member further includes an upper surface having alternating transverse ribs and recesses, and a lower surface having alternating longitudinal ribs and recesses. The ribs serve to reinforce the shelf member both longitudinally and transversely. Each shelf member further comprises an outward projecting support rail extending along one or more edges of each shelf member. A connecting mechanism simultaneously engages the support rails of adjacent shelf members and retains the adjacent shelf members in fixed relation with each other.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
132 words
In a shelf system of the type having a plurality of elongated support posts, the support posts including grooves around their periphery at spaced intervals along the post longitudinal axes, having shelf means and having means for supporting said shelf means on said support posts, said means for supporting cooperating with said support post grooves, the improvement wherein said shelf means comprise generally rectangular shelf members having shelf connecting means mutually engaging each other, and aperture means for receiving said post means and, said aperture means having an enlarged recess means for receiving said means for supporting and said means for supporting means comprising unitary clip means having a first portion substantially surrounding a support post within a support post groove and a second portion configured to nest within said recess means.
Claim 2
Dependent Claim
132 words
