US Patent 6908000 Multi-tiered corner shelving unit

A modular corner shelving system has a plurality of panels arranged vertically stacked and spaced apart. Each panel has an upper surface, a pair of back edges, a back corner, at least one front edge, and a plurality of sockets. One of the sockets is a rear socket positioned near the back corner. Each socket defines a top receptacle accessible from the upper surface and a bottom receptacle accessible from beneath the panel. A plurality of elongate risers each have a lower end received in a top receptacle of one of the sockets of one panel and an upper end received in a bottom receptacle of a corresponding one of the sockets of an adjacently upward panel. The system can also have at least one turntable assembly positioned on one of the plurality of panels that is rotatable about a generally vertically oriented axis relative to the panel. Each rear socket can also be adapted to absorb forces applied thereat by permitting relative movement between a riser received therein and the respective panel.
