Abstract
Abstract The four upright posts which project from the corners of a pallet platform each have a tubular base portion fixed to the platform and a top portion of the same tubular material. In the operative position of the post, longitudinally tapering recesses and projections of the two portions conformingly engage each other, and the bore of the top portion is conformingly engaged by a core fixed to the base portion and projecting from the bore of the same. A transverse pin between two projections of the top portion is received in a longitudinal guide slot of the core, thereby permitting the top portion to be lifted longitudinally from its operative position to an intermediate position in which the projections and recesses are disengaged, and thereafter to be folded toward the platform for compact storage of the pallet or outward to facilitate loading and unloading.

Claim 1
Independent Claim
308 words
A pallet comprising a platform defining a loading surface and a plurality of posts distributed about the circumference of said surface, a. each post having an elongated base portion fixedly fastened to said platform and an elongated top portion, b. each portion having an outer skin, c. said top portion being formed with an elongated bore extending longitudinally within said skin of the top portion, d. said base portion having an elongated core part attached thereto, said core part longitudinally projecting from said skin of said base portion and being received conformingly in said bore of the top portion in an operative position in which said portions are aligned longitudinally and substantially at right angles to said surface, 1. said skins, said bore, and said core part each being of substantially uniform angular cross section, e. each of said skins being formed with two longitudinal projections and recesses, each projection conformingly engaging a recess on the other portion in said operative position, 1. in each of said portions, said two recesses being arranged opposite each other, and said projections being arranged opposite each other and angularly offset from said recesses, 2. each recess and elongation tapering in the direction of elongation of the associated portion, 3. a portion of said core part projecting longitudinally from said skin of said base portion beyond the projections of said base portion, 4. said core part being formed with a longitudinal slot extending into said projecting portion of said core part, and f. a hinge pin connecting the two projections of said top portion, said hinge pin being received in said slot and guiding longitudinal movement of said top portion relative to said base portion toward and away from said operative position while permitting angular movement of the top portion relative to the base portion when said projections and recesses are disengaged.
