Abstract

A knock-down, plastic pallet comprises spaced longitudinal stringers and boards extending transversely of the stringers. The stringers and boards are held in interlocked relationship by an arrangement of integral notches and shoulders.

Claims

1. A plastic pallet assembly comprising a plurality of spaced longitudinal stringers, each stringer having on at least its upper surface a plurality of shoulders and notches and a plurality of boards extending transversely of the stringers and having shoulders and notches of equivalent size and shape to those of the stringer, said shoulders and notches of the stringers and boards in interlocked relationship with each other with the shoulders of the stringers positioned in the notches of the boards and the shoulderS of the boards positioned in the notches of the stringers.

2. A plastic pallet assembly comprising a plurality of spaced longitudinal stringers and a plurality of boards extending transversely of the stringers, each board having a plurality of grooves including shoulders and notches, each stringer having shoulders and notches of equivalent size and shape to those of the board, said shoulders and notches of the stringers and boards in interlocked relationship with each other with the shoulders of the stringers positioned in the notches of the boards and the shoulders of the boards positioned in the notches of the stringers.

3. A plastic pallet assembly comprising a plurality of spaced longitudinal stringers, each stringer having on at least its upper surface a plurality of grooves including shoulders and notches and a plurality of boards extending transversely of the stringers and having shoulders and notches of equivalent size and shape with those of the stringer, said shoulders and notches of the stringers and boards in interlocked relationship with each other with the shoulders of the stringers positioned in the notches of the boards and the shoulders of the boards positioned in the notches of the stringers.

4. For use in a plastic pallet assembly, a stringer having on at least its upper surface shoulders and notches adapted for interlocking relationship with a board having shoulders and notches corresponding in size and shape with those of the stringer so that when in such relationship the shoulders of the stringer are positioned in the notches of the board and the shoulders of the board are positioned in the notches of the stringer.
