Gravity-feed shelf and components therefor
First Claim
1. A plastic track component for a gravity feed shelf comprising a web panel having an upper article supporting surface, a flange panel integral with one side edge of said web panel and forming therewith a substantially "L"-shaped structure, a plurality of spaced ribs formed on said article supporting surface and extending the length of said web panel parallel with said flange panel, said ribs projecting upwardly from said article supporting surface and being of generally triangular cross section, an elongate notch formed in said web panel and extending parallel to and adjacent the other side edge of said web panel and remote from said flange panel and providing a frangible zone by which a portion of said web panel between said notch and said other side edge can be broken away from said web panel so as to reduce the width of said web panel, said notch extending the length of said web panel intermediate a pair of said ribs and being formed in the surface of said web panel opposite to said article supporting surface, said track component being formed of high-impact polystyrene having a lubricant material dispersed therein.

Abstract
This invention relates to a gravity-feed shelf and to low friction tracks for use in such shelves. The tracks comprise a web panel and an integral flange panel together providing an "L"-shaped structure and are characterized by a frangible zone by which a portion of the web panel can be broken away from an adjacent portion to reduce the width of the web panel, whereby the tracks readily can be adapted for use in conjunction with various sizes of packages and/or single bottles.
