Abstract
Abstract A pallet which includes a top and a bottom pallet surface of corrugated paperboard or the like which are fastened to a number of blocks of a plastic material such as polystyrene by foldable interlocking elements. These interlocking elements are precut or otherwise formed in the pallet surfaces, and are lockingly affixed to the blocks by extending them into a void in the blocks. Upon being extended into the voids, the interlocking elements lockingly engage with offset shoulder means therein, to automatically lock the pallet surfaces to the blocks.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
128 words
A pallet which can be stored and/or shipped knocked down and easily and quickly assembled for use without the need of any tools comprising, at least a top pallet surface and a plurality of blocks affixed to said top pallet surface to support the latter and in predetermined spaced positions, said top pallet surface having interlocking tabs at least corresponding in number to the blocks affixed thereto pre-formed therein, each of said blocks having a void therein for receiving said interlocking tabs, said interlocking tabs being foldable into said voids by means of a finger operation, said interlocking tabs and said voids being correspondingly formed such that said interlocking tabs releasably lock within said voids beneath shoulders formed therein to affix said blocks to said top pallet surface.
Claim 2
Dependent Claim
128 words
A pallet which can be stored and/or shipped knocked down and easily and quickly assembled for use without the need of any tools comprising, at least a top pallet surface and a plurality of blocks affixed to said top pallet surface to support the latter and in predetermined spaced positions, said top pallet surface having interlocking tabs at least corresponding in number to the blocks affixed thereto pre-formed therein, each of said blocks having a void therein for receiving said interlocking tabs, said interlocking tabs being foldable into said voids by means of a finger operation, said interlocking tabs and said voids being correspondingly formed such that said interlocking tabs releasably lock within said voids beneath shoulders formed therein to affix said blocks to said top pallet surface.
