SHELVING SYSTEM HAVING TWO SETS OF LOCKING TAPERS

摘要

A shelving apparatus includes a vertically extending first leg (2) having a first end with a frusto-conical outer surface (4). A horizontal shelf (10) has a frusto-conical hole. A vertically extending second leg (16) has a first end with (a) a frusto-conical inner surface (24) having a taper shaped to engage the frusto-conical outer surface (4) of the first leg (2), and (b) a frusto-conical outer surface (20) having a taper shaped to engage the frusto-conical inner surface (12) of the shelf hole. Preferably, all engaging frusto-conical surfaces and holes are coaxial and cofrustal Alternative tapered structures for the first and second legs and shelf hole may be provided.
