Industrial pallets and method of manufacturing

Claim 2

In a pallet assembly, including a top deck, a bottom deck, outboard stringer means interposed between said decks to provide a space between said decks, and intermediate stringer means disposed between said outboard stringer means to divide the space between the decks into entryways for a forklift, the improvement wherein at least one of said decks comprises a plurality of deckboards of relative long and short lengths, a pair of said long deckboards extending the full distance across said stringer means at opposite ends thereof, said short deckboards being disposed between said long deckboards and extending less than the full distance across said outboard stringer means but greater than the distance between the outboard stringer means and said intermediate stringer means, said short deckboards being arranged on said stringer means so that they extend inwardly from opposite outboard stringer means and have free end portions cantilevered in opposite directions across said intermediate stringer means and interdigitate with one another in the zone of said intermediate stringer means, and means fastening said deckboards to said stringer means to form a unitary pellet structure.

Claim 3

A pallet assembly according to claim 1 wherein said outboard stringer means includes a pair of stringer members, and said intermediate stringer means includes a medial stringer member disposed between and parallel to said outboard stringer members about halfway therebetween.

Claim 4

A pallet assembly according to claim 2 wherein said deckboards engage one another laterally along the medial stringer member.

Claim 5

A pallet assembly according to claim 1 wherein said short deckboards are notched in the zone of said intermediate stringer means and alternate ones laterally engage one another to provide between adjacent deckboards a gap of less width than the width of the short deckboards.

Claim 6

A pallet assembly according to claim 1 wherein each of said outboard stringer means has a pair of spaced notches in one edge and said deck extends across the stringer means on the edge opposite said one edge.

Claim 7

A pallet assembly according to claim 1 wherein one pair of said short deckboards extend inwardly diagonally from said outboard stringer means to engage laterally one another across the intermediate stringer means, and another pair of short deckboards extend inwardly across said intermediate stringer means to form an oblique angle with respect to said one deckboard pair.

Claim 8

A pallet assembly according to claim 1 wherein said long deckboards are wide relative to said short deckboards.

Claim 9

A pallet assembly according to claim 1 including at least another long deckboard extending across said intermediate stringer about midway between said pair of long deckboards.

Claim 10

A pallet assembly according to claim 1 wherein both decks are of like construction.

Claim 11

In a pallet assembly, including a top deck, a bottom deck, outboard stringer means interposed between said decks to provide a space between said decks, and intermediate stringer means disposed between said outboard stringer means to divide the space between the decks into entryways for a forklift, the improvement wherein at least one of said decks comprises a plurality of deckboards of relative long and short lengths, a pair of said long deckboards extending the full distance across said stringer means at opposite ends thereof, said short deckboards being disposed between said long deckboards and extending less than the full distance across said outboard stringer means but greater than the distance between the outboard stringer means and said intermediate stringer means, said short deckboards being arranged on said stringer means so that they extend inwardly from opposite outboard stringer means and have free end portions cantilevered in opposite directions across said intermediate stringer means, and means fastening said deckboards to said stringer means to form a unitary pallet structure, said intermediate stringer means including a pair of inboard stringer members disposed in spaced parallel relation between said pair of outboard stringer means, certain ones of said short deckboards extending inwardly from the outboard stringer means in endwise alignment in cantilever fashion across said inboard stringer members, and certain other ones of said short deckboards extending across only said inboard stringer members in cantilever fashion to terminate with the free ends spaced from both of said outboard stringer means.

Claim 12

In a pallet assembly, including a top deck, a bottom deck, outboard stringer means interposed between said decks to provide a space between said decks, and intermediate stringer means disposed between said outboard stringer means to divide the space between the decks into entryways for a forklift, the improvement wherein at least one of said decks comprises a plurality of deckboards of relative long and short lengths, a pair of said long deckboards extending the full distance across said stringer means at opposite ends thereof, said short deckboards being disposed between said long deckboards and extending less than the full distance across said outboard stringer means but greater than the distance between the outboard stringer means and said intermediate stringer means, said short deckboards being arranged on said stringer means so that they extend inwardly from opposite outboard stringer means and have free end portions cantilevered in opposite directions across said intermediate stringer means, and means fastening said deckboards to said stringer means to form a unitary pallet structure, said intermediate stringer means including a pair of inboard stringer members disposed in spaced parallel relation between said pair of outboard stringer means, certain ones of said short deckboards extending inwardly from the outboard stringer means in endwise alignment in cantilever fashion across said inboard stringer members, and certain other ones of said short deckboards extending across only said inboard stringer members in cantilever fashion to terminate with the free ends spaced from both of said outboard stringer means.

Claim 13

A pallet assembly according to claim 10 wherein said certain ones and other ones of said deckboards alternate in said deck.

Claim 14

A pallet assembly according to claim 11 wherein said short deckboards interdigitate with and laterally engage one another in the zone of said inboard stringer members in said deck.

Claim 15

A pallet assembly according to claim 12 wherein said certain ones of said deckboards laterally engage said long deckboards.

Claim 16

A pallet assembly according to claim 12 wherein said certain other ones of said deckboards laterally engage said long deckboards.

Claim 17

A pallet assembly according to claim 10 wherein said deckboards engage one another laterally along said intermediate stringer means.

Claim 20

A method according to claim 16 including the steps of abutting the deckboards edgewise before fastening along said intermediate stringer to provide gaps between the deckboards.

Claim 21

A method according to claim 17 wherein the other selected deckboards have random lengths and including the step of trimming the outboard ends of the deckboards after having been abutted edgewise.
