Abstract
Abstract A fork lift truck pallet folded from blanks of board material and having identical top and bottom wall panels each with boxlike structures folded from opposite marginal edge portions. Wall members of the box-like structures normal to the top and bottom wall panels provide compressive strength, and resistance to lateral collapse is provided by spacing members of rectangular tube-like section disposed at right angles between the box-like structures. The spacing members also provide a measure of compressive strength.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A fork lift truck pallet folded from board material comprising a top panel and a bottom panel each of the top and bottom panels comprising a unitary structure having a load bearing surface, a first section disposed at a right angle to the load bearing surface forming an exterior side wall of the pallet, a second section disposed at a right angle to said first section and parallel and intermediate the plane of said top and bottom load bearing surfaces and at least one other section disposed at right angles to said second section and parallel to said first section forming an interior side wall of the pallet; and, at least one spacing member of generally rectangular tube-like section positioned intermediate the load bearing surfaces of the top and bottom panels at right angles to the side walls and between the two innermost interior side walls of the pallet.
Claim 2
Dependent Claim
149 words
A fork lift truck pallet folded from board material comprising a top panel and a bottom panel each of the top and bottom panels comprising a unitary structure having a load bearing surface, a first section disposed at a right angle to the load bearing surface forming an exterior side wall of the pallet, a second section disposed at a right angle to said first section and parallel and intermediate the plane of said top and bottom load bearing surfaces and at least one other section disposed at right angles to said second section and parallel to said first section forming an interior side wall of the pallet; and, at least one spacing member of generally rectangular tube-like section positioned intermediate the load bearing surfaces of the top and bottom panels at right angles to the side walls and between the two innermost interior side walls of the pallet.
Claim 3
Dependent Claim
203 words
A fork lift truck pallet folded from board material comprising a top panel and a bottom panel, each of the top and bottom panels comprising a unitary structure having a load bearing surface, a first section disposed at a right angle to the load bearing surface forming an exterior side wall of the pallet, a second section disposed at a right angle to said first section and parallel and intermediate the planes of said top and bottom load bearing surfaces, a third section disposed at a right angle to the second section, parallel to the first section and intermediate the exterior side walls of the pallet, forming an interior side wall of the pallet, at least one other section disposed parallel to the second section and intermediate the planes of said second section and said load bearing surface and at least one other section disposed parallel to the first and third sections and forming a further interior side wall of the pallet; and, at least one spacing member of generally rectangular tube-like section positioned intermediate the load bearing surfaces of the top and bottom panels at right angles to the side walls and between the two innermost interior Ide walls of the pallet.
Claim 4
Dependent Claim
203 words
A fork lift truck pallet folded from board material comprising a top panel and a bottom panel, each of the top and bottom panels comprising a unitary structure having a load bearing surface, a first section disposed at a right angle to the load bearing surface forming an exterior side wall of the pallet, a second section disposed at a right angle to said first section and parallel and intermediate the planes of said top and bottom load bearing surfaces, a third section disposed at a right angle to the second section, parallel to the first section and intermediate the exterior side walls of the pallet, forming an interior side wall of the pallet, at least one other section disposed parallel to the second section and intermediate the planes of said second section and said load bearing surface and at least one other section disposed parallel to the first and third sections and forming a further interior side wall of the pallet; and, at least one spacing member of generally rectangular tube-like section positioned intermediate the load bearing surfaces of the top and bottom panels at right angles to the side walls and between the two innermost interior Ide walls of the pallet.
Claim 5
Dependent Claim
46 words
