Abstract
Abstract An all-steel winged pallet has a deck formed of hollow steel tubes welded at each end to a support member. The support members extend perpendicular to the deck tubes and parallel to each other and have generally U-shaped cross-sections that are mirror images to each other. The inner side of the U is welded to the tubes at a location spaced inwardly from the respective end of the tube, and the outer side is bent outwardly to form a shelf and is then bent upwardly to be welded to the end region of the tubes. The shelf includes a roller contact area under the outermost part of the deck tubes to ride on rollers of a gravity-flow rack system and a guide that extends longitudinally along the shelf to provide a surface against which the rollers can bear.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
278 words
A pallet comprising: a plurality of spaced apart hollow steel tubes comprising first, intermediate, and last tubes substantially parallel to each other and defining a substantially flat deck plane, wherein the length of the tubes define the width of the pallet and the distance between the first and the last of the plurality of tubes define the length of the pallet; and first and second sheet steel support members substantially perpendicular to the tubes, each of said support members comprising a portion of U-shaped cross-section that extends the length of the pallet and that has a bight portion that forms a foot, and first and second sides, the first side being welded to the tubes at a location spaced inwardly from one end region of the respective tubes, the second side having an extended portion bent outwardly, wherein said extended portion comprises first and second horizontal portions vertically offset from each other by an integral web portion spaced horizontally outward from said second side and extending the length of the pallet with said first and second horizontal portions and said web portion all being integrally formed from said extended portion; wherein, said second horizontal portion is outward of said web portion defining a roller contact area, and with the edge of the extended portion of the second side being welded to said one end region of the respective tubes; and wherein, said web portion defines guide member means spaced horizontally outward from said second side by said first horizontal portion and positioned inward from said second horizontal portion defining said roller contact area, whereby the pallet will accurately follow a rail system comprising a plurality of aligned rollers.
Claim 2
Dependent Claim
278 words
A pallet comprising: a plurality of spaced apart hollow steel tubes comprising first, intermediate, and last tubes substantially parallel to each other and defining a substantially flat deck plane, wherein the length of the tubes define the width of the pallet and the distance between the first and the last of the plurality of tubes define the length of the pallet; and first and second sheet steel support members substantially perpendicular to the tubes, each of said support members comprising a portion of U-shaped cross-section that extends the length of the pallet and that has a bight portion that forms a foot, and first and second sides, the first side being welded to the tubes at a location spaced inwardly from one end region of the respective tubes, the second side having an extended portion bent outwardly, wherein said extended portion comprises first and second horizontal portions vertically offset from each other by an integral web portion spaced horizontally outward from said second side and extending the length of the pallet with said first and second horizontal portions and said web portion all being integrally formed from said extended portion; wherein, said second horizontal portion is outward of said web portion defining a roller contact area, and with the edge of the extended portion of the second side being welded to said one end region of the respective tubes; and wherein, said web portion defines guide member means spaced horizontally outward from said second side by said first horizontal portion and positioned inward from said second horizontal portion defining said roller contact area, whereby the pallet will accurately follow a rail system comprising a plurality of aligned rollers.
Claim 3
Dependent Claim
47 words
The pallet according to claim 1 in which the tubes are hollow and rectangular in cross section and have a width approximately twice as great as the thickness thereof and are spaced laterally from each other by a distance at least substantially as great as said width.
Claim 4
Dependent Claim
23 words
The pallet according to claim 1 in which the first and second sheet steel support members are substantially mirror images of each other.
Claim 5
Dependent Claim
49 words
The pallet according to claim 1 in which the first side of each of the sheet steel support members is bent substantially perpendicularly to form a flange that is held against the underside of the tubes at the location spaced inwardly from one end region of the respective tubes.
Claim 6
Dependent Claim
60 words
The pallet according to claim 4 in which the flange is bent outwardly toward the second side of that support member and the weld between the first side and each of the respective tubes comprises a fillet at the intersection of the respective tubes and the surface of the first side opposite the direction in which the flange is bent.
Claim 7
Dependent Claim
46 words
The pallet according to claim 4 in which the second side comprises an upwardly bent portion outboard of the roller contact area, and an inwardly bent flange at the edge of the upwardly bent portion and overlapping one end of each of the hollow steel tubes.
Claim 8
Dependent Claim
28 words
The pallet according to claim 6 comprising a weld joining the edge of the inwardly bent flange and the adjacent portion of each of the hollow steel tubes.
Claim 9
Dependent Claim
57 words
The pallet according to claim 6 in which the upwardly bent portion extends up from the outer part of the roller contact area by a distance greater than the thickness of the tubes, whereby there is a space between the part of the second side comprising the roller contact area and the juxtaposed surfaces of the tubes.
Claim 10
Dependent Claim
31 words
The pallet according to claim 6 in which the part of the second side that comprises the roller contact area is substantially in contact with the juxtaposed surface of the tubes.
Claim 11
Dependent Claim
38 words
The pallet according to claim 1 comprising a sheet metal bridging member extending across the U-shaped cross section of each of the support members adjacent the bight portion thereof and welded to the first and second sides thereof.
Claim 12
Dependent Claim
18 words
The pallet according to claim 10 in which the bridging member is between the first and second sides.
Claim 13
Dependent Claim
50 words
The pallet according to claim 11 in which each of the bridging members comprises a short piece of steel tubular material having a channel therethrough similar in cross section to the hollow steel tubes, the channel extending in a direction perpendicular to the longitudinal direction of the respective roller tracks.
