Abstract
Abstract A platform conveyor is provided with a plurality of flat panels. Each of the panels has on its opposite edges closed eyes which are spaced from one another and integral with the panel. The eyes are insertable into the spaces between the eyes of an adjacent panel member and connectable by means of bars insertable through adjacent eyes.

Claim 1
Independent Claim
368 words
In a platform conveyor, the combination comprising a plurality of flat panel members of plastic material articulated together along transversely extending edges thereOf, an upper surface on each of said flat panel members to support a load, said panel members having openings therein, a plurality of eyes formed along each transversely extending edge of each of said panel members, said eyes being apertured and the eyes of adjacent panel members being aligned to receive an interconnecting hinge member to connect said panel members together, the eyes on one transversely extending edge of each panel being staggered relative to the eyes on the opposite edge thereof, each of said eyes being positioned to extend below said upper surface of its associated panel and having a substantially circular cross section, said opposite panel edges having spaces formed between said eyes for receiving the projecting eyes of an adjacent panel, curved undercut tip walls formed along said panel edges at said spaces for receiving therein upper quadrants of said eyes of an adjacent panel member, transversely extending ends of said tip walls being located at the top of said eyes received therein, said curved tip walls having an undercut curvature substantially equal to the outer diameter of said eyes and having an arcuate length of about one quadrant, said eyes fitting snugly within said eyes defining said recesses, each of said eyes having a transverse width substantially equal to the width of one of said receiving spaces so that the panel members are intermeshed and closely fitted, said eyes of adjacent panel members extending in transverse, parallel rows across the width and adjacent to end edges of said conveyor, said eyes having a substantially greater thickness and depth than said portion of said panel member therebetween and adding rigidity and stability to said conveyor, and depending end walls depending below the lower surface of said panel members and joined to said eyes adjacent said end edges of said panel members and having a depth greater than the depth of said portion of said panel members and thereby adding rigidity to said panel members, and mating pins and holes on said end walls of said laterally adjacent panel members interconnecting the same.
