Abstract

An easily mountable and repositionable cantilevered shelf supported from the rear wall of a commercial refrigerator or freezer cabinet on two vertical support members secured inside on the rear wall. Each support member has longitudinal flanges projecting forward from an elongate vertical base fastened to the rear wall and formed with front channels facing toward the base part, opposed flanges of the channels of the two support members having notches along their length. Shelves are made from rod and wire construction with a solid cross bar across the rear upper shelf edge. The ends of the cross bar project laterally as short trunnions and hook into matched pairs of notches in the facing channel flanges of each support. Rearwardly projected lower rods incline downwardly and rearwardly on each side of the shelf and their ends abut against the mid-portions of the support channels so the shelf can be fulcrumed about the abutments to lock the trunnion ends of the cross bar into the associated, rearward directed, facing notches.

Dependent claims

A cantilevered shelf and support construction comprising:

at least one planar shelf means, with means rigid with the upper rear of said shelf means providing a short lateral trunnion like projection extending from adjacent each top rear corner of said shelf means and rearwardly disposed abutment means depending from the sides of said planar shelf means to a location below said projections and in front of a plane through the forward surface of said projections and perpendicular to the planar shelf means;
and at least a pair of parallel spaced apart vertically disposed elongate shelf support brackets secured to a vertical surface, each bracket having a front laterally projected portion facing and spaced forward from the vertical surface, the central portion of said lateral portion providing an elongate vertical abutment surface for an associated one of said shelf abutment means, the lateral portions of said pair of brackets facing each other and having their under portions provided with a plurality of matched, spaced apart, open ended slots opening toward and spaced from the vertical surface a distance greater than the cross-section dimension, in a fore and aft direction, of said projections;
said projections being received in a matched pair of said slots with said abutment means engaging associated said abutment surfaces, the projections being maintained in the slots by the downward force of said shelf means fulcrumed on said abutment means;
whereby said shelf means can be repositioned by upward tilting and rearward shifting of said shelf means to remove the projections from engagement with associated said slots and permitting vertical repositioning of the shelf means to a different location.
