Shelving system

Abstract

A shelving system, of the type adapted for swift assembly and disassembly, has an improved upright and shelf structure in which each shelf is swiftly attachable, without the use of tools, at its corners to transversely spaced posts of the upright. The upright is a ladder type, incorporating vertically spaced cross braces extending between vertical posts each of which comprises inner and outer post elements that allow insertion of a shelf without necessity of its being tilted or cocked. Each shelf is formed at its corners with right-angular, inwardly extending locking tongues or tabs, initially locatable, during assembly, in wide spaces defined between the inner and outer post elements. With the shelf in horizontal position, it is permitted movement downwardly from the wide spaces into narrower spaces in which the corners of the shelf lock, with the shelf being supported upon the cross braces of the uprights. Each upright is usable as a standard common to shelves adjoining each other at opposite sides of the upright, by formation of the upright posts with rectangularly spaced post elements defining side-by-side locking spaces while at the same time strongly reinforcing the uprights so that they may support heavy loads.
