ABSTRACT:
A shelf assembly which is assembleable without extraneous fasteners and which may be shipped flat and ready for attachment to a pair of spaced standards. The assembly comprises an expansive shelf of formed sheet metal having an upper shelf surface portion and a lower portion which provides groups of spaced slots opening into hollows within the shelf. Shelf support brackets, each having an expansive main body portion, hooks for supporting the assembly on a standard and a pair of mounting ears integral with the bracket extend laterally from the upper regions of the bracket main body portion. The mounting ears are seated within the hollows of a corresponding group of slots. The ears on each bracket have projections by which the shelf and bracket are interconnected. At least one projection is a protuberance, the combined width of the ear and the protuberance being greater than the width of the slot portion through which that ear entered. One ear has a hook-like projection. The projections serve to resist withdrawal and separation of the bracket from the shelf.
When a bracket is to be connected to a shelf, the hook-like projection is inserted through one slot and the other ear bearing the projection is snapped through the other slot. The bracket is then rotated 90 degrees to position it for securance to a hook receiving standard. The bracket, the shelf assembly and the method of assembling them are all disclosed herein.
