Abstract
A modular double deck shipping pallet assembly which may be disassembled to smaller volume for shipping, reassembly and reuse. All of the components of the assembly are injection molded from recyclable or recycled thermoplastic polymers.
Claims25
A pallet assembly, which may be disassembled to smaller volume for shipping, reassembly and reuse comprising (1) a rigid substantially planar rectangular upper deck having an upper load surface and lower support surface, (2) a plurality of detachable hollow cupped feet having a symmetrical cross section, the open end of which feet depend from and are attached to the upper deck through openings in the deck assembly and the cupped feet are arranged in a centrally positioned symmetrical array of lines and columns, each line and column being comprised of at least three such feet in both the longitudinal and transverse directions of the array, the cupped end of each of the feet being linked both longitudinally and transversely by (3) a rigid substantially planar rectangular lower deck having an upper surface and a lower surface and a plurality of openings through which the cupped feet are connected to the lower deck at or near the cupped end of each of the feet, the open ends of the cupped feet being rotatably attached to the upper deck and the cupped end of the feet being rotatably attached to the lower deck by means of snap-fit connections which are co-rotatable with the upper deck connections of the cupped feet, the complementary components of which connections are molded into the periphery of the feet and the inside surface of the foot attachment openings in the upper and lower decks, the decks and cupped foot members all being formed by injection molding of a molten normally solid thermoplastic polymer.
A pallet assembly which may be disassembled to smaller volume for shipping, reassembly and reuse comprising (1) a rigid substantially planar rectangular upper deck having an upper load surface and lower support surface, (2) a plurality of detachable hollow cupped feet having a symmetrical cross section, the open end of which feet depend from and are attached to the upper deck through openings in the deck assembly and the cupped feet are arranged in a centrally positioned symmetrical array of lines and columns, each line and column being comprised of at least three such feet in both the longitudinal and transverse directions of the array, the cupped end of each of the feet being linked both longitudinally and traversely by (3) a rigid substantially planar rectangular lower deck having an upper surface and a lower surface and a plurality of openings through which the cupped feet are connected to the lower deck at or near the cupped end of each of the feet, the open ends of the cupped feet being rotatably attached to the upper deck, and the cupped end of the feet being rotatably attached to the lower deck by means of snap-fit connections which are co-rotatable with the upper deck connections of the cupped feet, the complementary components of which connections are molded into the periphery of the feet and the inside surface of the foot attachment openings in the upper and lower decks, the decks and cupped foot members all being formed by injection molding of a molten normally solid thermoplastic polymer, wherein the upper deck is formed from rectangular interlocking modular sections, and wherein a plurality of the foot attachment openings in the upper deck are located across joints between two or more modular upper deck sections by which attachment of the cupped feet to the upper deck also serves to interlock the modular sections thereof.
