Abstract
Abstract The cart has an upright, open frame, a plurality of trays arranged one over the other with anti-bend pivot means supporting and connecting each tray with the frame so as to be tiltable as between a horizontal product load position and an angled product take-out position with each tray being molded from fiberglass reinforced plastic including vertically oriented, beam-like sections, a full bottom, and a pair of metal rods molded with the tray and disposed on one side of the tilt axis and the fiberglass reinforced plastic, the vertical sections, the metal rods, and the pivot means all cooperating to minimize tray flexure and the weight distribution provided by the tray structure and material on opposite sides of the pivot axis causing the tray to tilt to the product load position when the tray is not carrying products and causing the tray to tilt to the product take-out position when the tray is filled with products.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
211 words
A tray for a point-of-sale display cart formed as by fiberglass reinforced polyester plastic molded into a tray structure comprising: a rectangular shaped flat bottom having a front edge, a rear edge, and a pair of side edges; the underside of said bottom having first and second sets of vertical ribs, the ribs of the first set extending in a direction between the front and rear edges and the ribs of the second set extending in a direction between the side edges and intersecting ribs of the first set; the top side of said bottom having a plurality of parallel beads, each bead extending from said rear edge toward said front edge and terminating at a point spaced from the front edge; support means formed on ribs of said first set for receiving pivot means to support the tray for tilting motion about an axis; a pair of ribs of said second set between said rear edge and said axis each having a metal rod molded therewith; a vertical front wall extending up from said front edge; a pair of product-retaining side walls respectively extending up from said side edges; and said vertical front wall including a groove extending along said front edge with drain holes respectively at opposite ends thereof.
