Abstract
A pallet for carrying and storing goods having lower and upper load bearing decks and separators disposed between and secured to the decks enabling a pallet jack or fork lift to be inserted between the panels. Locking means are provided in the decks so that when identical empty pallets are stacked one upon the other, they interlock so as to resist relative translational motion between the two. This feature also reduces the stack height of the pallets.
Claims8
A pallet for carrying and storing goods comprising:
- lower and upper load bearing decks and separators disposed between and secured to the decks enabling a fork lift or pallet jack to be inserted between the decks,
- and locking means formed in the lower and upper decks and confined to the planes of the decks for interlocking a pair of identical pallets together against relative translational motion when stacked in overlapping relationship,
- said upper and lower decks each being composed of a plurality of parallel boards, said locking means comprising ribs and grooves formed in said boards,
- each of the boards in the upper deck having in its top surface a plurality of ribs and grooves, and each of the boards in the lower deck having in its bottom surface a plurality of ribs and grooves,
- the boards of one of the decks having a pair of grooves of substantially the same width separated by a rib of greater width,
- and the boards of the other deck having a pair of ribs each adapted to fit into the grooves in the boards of the other deck of another pallet and having a relatively wide groove for receiving a rib on the boards of the other deck,
- the configuration of the ribs and grooves in the upper and lower deck boards causing the pallets to interlock in an alternately offset configuration when the pallets are alternately reversed 180.degree. with respect to one another.

A pallet array comprising:
- at least two pallets each comprising,
- a first plurality of like thickness elongated boards disposed flatly and extending in parallel and forming an upper planar load bearing deck,
- a second plurality of like thickness elongated boards disposed flatly and extending in parallel and forming a lower planar load bearing deck,
- a plurality of stringers interconnecting the upper and lower decks so as to dispose the decks in parallel planes,
- said stringers being of like height, disposed transversely to said elongated boards and spaced relative to each other a greater distance than the spacing between boards of either deck,
- said upper and lower decks each having means defining ribs and grooves in the outer surface remote from the stringers,
- the ribs and grooves in the upper and lower deck boards causing the pallets to interlock when stacked in an alternately offset manner with a rib of one deck board and a rib of an adjacent deck board in the same deck interlocking with spaced respective grooves in the same deck board of a second pallet stacked thereon.
