Abstract
Abstract The combination of a molded liner in a refrigerating unit and a shelf which is positionable between horizontal grooves formed on opposite walls at vertical increments in the liner. The length of the main shelf is less than the distance between opposite grooves. However, the shelf has an extension portion which is pivotally mounted to its front rim to cause its overall length to be sufficient to be supported by the grooves. The extension portion is restricted from pivotal movement upwardly from its aligned position with the shelf, but is allowed to pivot downwardly so as to allow the shelf to be moved either upwardly or downwardly to a new position in the refrigerator.

Claim 1
Independent Claim
229 words
The combination comprising a refrigerator having a molded liner enclosure, said molded liner enclosure having a rear wall and a door opening oppositely of the rear wall with front wall portions adjacent either side thereof, side walls connecting the front wall portions with the rear wall, said adjacent wall portions and rear wall having a plurality of vertically spaced horizontal grooves formed therein, said grooves in the front wall portion being horizontally aligned with corresponding grooves in the rear wall, said grooves defining platforms upon which a shelf may rest, a main shelf having a length which is generally less than the distance between the platforms on the front wall portions and the related platforms on the rear wall, a trim piece pivotally supported at the front edge of the main shelf, said trim piece being retractable to have a combined length with said main shelf which is less than the distance between said two platforms and being extensible to have a combined length with said main shelf which is greater than the distance between said two platforms, said shelf being receivable within any pair of said aligned grooves disposed oppositely of each other on said rear and front wall portions, and said shelf being adjustable from one pair of grooves to another pair of grooves either upwardly or downwardly by retraction and extension movements of said trim piece.
