Abstract
Two component parts of thermoplastic resin each being constructed with a deck board having integrally formed on one surface thereof a plurality of girders being disposed along opposite edge portions at each corner thereon and therebetween and along a line parallel to and midway between the edge portions and a multiplicity of ribs of lesser projection therefrom than the girders are readily assembled by melt adhesion to form a pallet for a fork lift which exhibits excellent strength and rigidity to bending.
Claims13
A pallet of thermoplastic resin material for use with a fork lift comprising:
- a pair of like component parts each having a deck board having an outer smooth and continuous planar surface whereby said pallet is reversible,
- at least one girder integrally formed on each of said deck boards along each of a pair of opposite edge portions thereof and on the deck surface between said edge portions,
- multiple reinforcing ribs integrally formed on said deck board and projecting therefrom a lesser distance than said girders,
- said component parts being secured together by melt adhesion, with the girders of one being melt adhered to the corresponding girders of the other, and
- wherein each of said girders comprises an oblong ring, said reinforcing ribs being disposed within and between said girders.
A pallet for use with a fork lift comprising:
- a pair of like component parts composed of a structure of lower foamed thermoplastic resin material having a non-foamed layer on the surface with each having a deck board and an outer smooth and continuous planar surface, whereby said pallet is reversible,
- at least one girder integrally formed on each of said deck boards along each of a pair of opposite edge portions thereof and on the deck surface between said edge portions,
- multiple reinforcing ribs integrally formed on said deck board and projecting therefrom a lesser distance than said girders,
- said component parts being secured together by melt adhesion with the girders of one being melt adhered to the corresponding girders of the other, and
- wherein each of said girders comprises an oblong ring, said reinforcing ribs being disposed within and between said girders.
