Patent ID: 7100781

Claim:
An adjustable shelving system comprising: a cylindrical support post having at least two slots disposed on an outer surface thereof and spaced axially along the support post, each slot comprising a lower horizontal surface that extends through the outer surface of the support post a first depth, each slot extending upward from its lower horizontal surface and tapering outward to the outer surface of the support post so that an upper distal end of each slot is at least substantially flush with the outer surface of the support post; a cylindrical collar having an outer surface, the outer surface having a substantially constant outer diameter along a length defined between a top and bottom edge thereof, which is slidably received over the support post; and an end cap that surrounds the collar, the end cap having an inner surface, the inner surface having a substantially constant inner diameter along a length defined between a top and bottom edge thereof; wherein the collar extends around the support post and terminates in two free ends with a gap disposed therebetween, the collar includes an annular flange extending from an outer surface of the collar and a radially inwardly extending cleat extending from an inner surface of the collar, the cleat is received in one of the slots of the support post so that the cleat engages the lower horizontal surface of one of the slots, and the collar is movable along the support post by upward pressure on the collar to slide the cleat upwards off of the lower horizontal surface of the slot and past the distal end of the slot.
