Abstract
Abstract A pallet having a rectangular shaped load carrying deck of generally uniform thickness. The deck is formed of several sheets of flexible wooden material with spring characteristics. The sheets of flexible wooden material are superimposed on one another and formed to be arcuate about a single axis. The sheets are glued together so as to constitute an arcuate structure substantially free from inherent tension forces in its unloaded condition and having sufficient elasticity to assume a substantially planar form under load. Supporting means are attached to the under convex side of the deck. The supporting means are arranged in a plurality of parallel rows extending in the direction of the single axis. One of the rows is located in the plane intersecting the axis and a line on the deck substantially corresponding to the central deck line. A second row of supports extend along the first outer edge portion of the deck and a third row of supports extend along a second outer edge portion of the deck.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
213 words
A pallet including: a rectangular load carrying deck of generally uniform thickness formed of several sheets of flexible wooden material having spring characteristics, the sheets being superimposed upon one another and formed to be upwardly concave about a single axis and glued together so as to constitute an upwardly concave structure substantially free from inherent tension forces in its unloaded condition and having sufficient elasticity to assume a substantially planar form under load, and supporting means attached to the under convex side of said deck, said supporting means being arranged in a plurality of parallel rows extending in the direction of the axis of curvature of the deck, one of said rows being located in a plane intersecting the axis and a line on the deck substantially corresponding to a transverse center deck line, a second row extending along a first outer edge portion of the deck and a third row extending along a second outer edge portion of the deck, the supporting means being of the same height so that all of the supporting means cannot touch a supporting surface for the pallet in the unloaded condition thereof but will allow the deck to assume a planar shape with all of the supporting means in contact with the supporting surface under load.
Claim 2
Dependent Claim
213 words
A pallet including: a rectangular load carrying deck of generally uniform thickness formed of several sheets of flexible wooden material having spring characteristics, the sheets being superimposed upon one another and formed to be upwardly concave about a single axis and glued together so as to constitute an upwardly concave structure substantially free from inherent tension forces in its unloaded condition and having sufficient elasticity to assume a substantially planar form under load, and supporting means attached to the under convex side of said deck, said supporting means being arranged in a plurality of parallel rows extending in the direction of the axis of curvature of the deck, one of said rows being located in a plane intersecting the axis and a line on the deck substantially corresponding to a transverse center deck line, a second row extending along a first outer edge portion of the deck and a third row extending along a second outer edge portion of the deck, the supporting means being of the same height so that all of the supporting means cannot touch a supporting surface for the pallet in the unloaded condition thereof but will allow the deck to assume a planar shape with all of the supporting means in contact with the supporting surface under load.
Claim 3
Dependent Claim
23 words
The pallet of claim 1 in which each of said supporting means includes a plurality of independently attached legs arranged in a row.
Claim 4
Dependent Claim
29 words
A pallet as claimed in claim 1, in which said supporting means includes at least one beam extending along a central line of the deck parallel to said axis.
Claim 5
Dependent Claim
19 words
A pallet as claimed in claim 2, in which the legs in each row are secured to underlying stringers.
Claim 6
Dependent Claim
16 words
A pallet as claimed in claim 1, in which each of said sheets consists of hardboard.
