Abstract
Abstract A pallet constructed from formed sheet material, such as a plastic sheet, having a generally planar load-supporting member from which downwardly depend hollow leg members and hollow stiffening members, the leg and stiffening members being of such configuration and dimensions and so disposed that sufficient rigidity is imparted to said load-supporting member that the latter is relatively undeformable under normal loads thereon.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
268 words
A pallet structure constructed of thin sheet material of substantially uniform thickness throughout, and having a generally planar load supporting member, a plurality of downwardly directed hollow legs formed from said sheet material and opening on the upper face of said load supporting member, said legs being symmetrically disposed with one leg disposed adjacent each corner of the load supporting member and intermediate legs disposed therebetween, said legs being so arranged that the fork of a lift truck may be inserted therebetween, a plurality of elongated downwardly directed hollow reinforcing ribs extending between such legs and opening on the upper face of said load-supporting member, the depth of said stiffening ribs being less than the depth of said legs to permit such a fork lift to pass under such stiffening ribs, said legs having reinforcing ribs which extend laterally outward from the asoicated leg sidewall and upwardly with the upper ends thereof opening on said load-supporting surface, a continuous reinforcing edge structure encircling said load-supporting member and formed from said sheet material, said edge structure comprising a first portion, of inverted U-shape, in transverse cross section, having a pair of spaced sidewalls and a top wall connecting said sidewalls, the inner sidewall of said portion extending upwardly from said planar load-supporting member to provide a peripheral abutment encircling the same, the outer sidewall terminating at its lower edge in an outwardly directed bottom wall, the latter having at its outer edge an upwardly directed sidewall to form a second portion of U-shape in transverse cross section, with the intermediate side wall forming a part of both U-shaped portions.

A pallet structure constructed of thin sheet material of substantially uniform thickness throughout, and having a generally planar load supporting member, a plurality of downwardly directed hollow legs formed from said sheet material and opening on the upper face of said load supporting member, said legs being symmetrically disposed with one leg disposed adjacent each corner of the load supporting member and intermediate legs disposed therebetween, said legs being so arranged that the fork of a lift truck may be inserted therebetween, a plurality of elongated downwardly directed hollow reinforcing ribs extending between such legs and opening on the upper face of said load-supporting member, the depth of said stiffening ribs being less than the depth of said legs to permit such a fork lift to pass under such stiffening ribs, said legs having reinforcing ribs which extend laterally outward from the asoicated leg sidewall and upwardly with the upper ends thereof opening on said load-supporting surface, a continuous reinforcing edge structure encircling said load-supporting member and formed from said sheet material, said edge structure comprising a first portion, of inverted U-shape, in transverse cross section, having a pair of spaced sidewalls and a top wall connecting said sidewalls, the inner sidewall of said portion extending upwardly from said planar load-supporting member to provide a peripheral abutment encircling the same, the outer sidewall terminating at its lower edge in an outwardly directed bottom wall, the latter having at its outer edge an upwardly directed sidewall to form a second portion of U-shape in transverse cross section, with the intermediate side wall forming a part of both U-shaped portions.
Claim 3
Dependent Claim
21 words
A pallet structure according to claim 1, wherein the respective top, bottom and sidewalls of said U-shaped portions are substantially flat.
Claim 4
Dependent Claim
41 words
A pallet structure according to claim 1, wherein the outer sidewall of the second U-shaped portion is provided with a longitudinally extending reverse bend to form a longitudinally extending downwardly directed flange defining the extreme outer edge of the pallet structure.
Claim 5
Dependent Claim
28 words
A pallet structure according to claim 1 wherein said legs and stiffening ribs are generally rectangular in horizontal cross section and generally U-shaped in transverse vertical cross section.
Claim 6
Dependent Claim
18 words
A pallet structure according to claim 1, wherein said legs and stiffening ribs are disposed on intersecting lines.
Claim 7
Dependent Claim
35 words
A pallet structure according to claim 1, wherein said U-shaped portion of said edge structure adjacent said load-supporting member has a substantially flat top wall and relatively flat sidewalls which diverge from said top wall.
Claim 8
Dependent Claim
39 words
A pallet structure according to claim 1, wherein said pallet is made from sheet stock having an initial thickness of from approximately 0.030 inch to approximately 0.150 inch and has a maximum thickness of approximately 0.080 to 0.500 inch.
Claim 9
Dependent Claim
14 words
A pallet structure according to claim 7, wherein said sheet stock is a polyethylene.
Claim 10
Dependent Claim
28 words
A pallet structure according to claim 7, wherein said pallet is made from single thickness of sheet stock having an approximate thickness of from 0.080 to 0.150 inch.
Claim 11
Dependent Claim
45 words
A pallet structure according to claim 7, wherein said pallet comprises a laminated structure having two spaced outer plies of sheet plastic of at least 0.030 inch, between which is disposed a sheet of foam plastic having a thickness of approximately at least 0.250 inch.
