Abstract
A single twin-sheet thermoformed plastic part has parallel bands of plastic forming fillets which allow stiff pallet deck segments to be folded after forming and locked together into a support structure with a planar upper deck spaced above a pallet lower deck with openings for lift truck tines. The lower deck has two segments joined by side stringers to the upper deck. Two central stringer segments extend along folding fillets from lower deck half segments to lock into place with the upper deck. The pallet is locked in its assembled configuration by a rod which passes through knuckles formed beneath the central stringers. The monocoque construction of the pallet provides for advantageous stiffness and load support capacity, while at the same time being economical to produce. For increased load-carrying capability, the pallet may be formed with a reinforcing substrate reinforced with a tubular steel insert. The pallet has interleaved step structure adjacent each plastic fillet which transfers vertical loads and also resists lateral deformation of the pallet.
