Abstract
Abstract A one-piece molded plastic platform having a planar upper load-receiving surface surrounded by a peripheral upwardly projecting flange is supported on a plurality of hardwood skids received within three-sided pockets defined by ribs molded so as to depend from the lower surface of the platform. Selected ones of the ribs are reinforced by molded gussets with each skid being locked in position by interengaging projections or transverse ribs on the platform and sockets or rib-receiving notches defined in the skids, appropriate mechanical fasteners completing the locking of the skids to the platform in a manner whereby there is no exposure of the fasteners. Load tying straps tie the load to the pallet with these straps being properly orientated by seats molded within the pallet flange.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
217 words
A pallet comprising a one-piece molded plastic platform having a planar upper load-receiving surface and a lower surface, a plurality of elongated wood skids underlying and engaged with selected portions of the lower surface of the plastic platform, said skids being in laterally spaced generally parallel relation to each other and presenting floor engaging, unencumbered planar bottom surfaces, the skids defining sliding supports for said platform of a height and spaced for the accommodation of lift equipment below said platform, and means for fixing the wood skids to the lower surface of said platform, said means for fixing the skids to the platform comprising upwardly opening notches transversely across the upper portions of the wood skids, integral hollow ribs depending from the corresponding selected portions of the lower surface of the platform and completely received within each said skid notch, each rib being elongated and substantially coextensive with the corresponding notch, fasteners engaged through said notch-received ribs and into the skids, the selected portions of the lower surface of the platform, other than said ribs, presenting planar surfaces coextensive with and engaged flat against the tops of the skids said molded plastic platform being capable of slight flexure so as to comform to a superimposed load upon the application of banding straps about the platform and load.
Claim 2
Dependent Claim
217 words
A pallet comprising a one-piece molded plastic platform having a planar upper load-receiving surface and a lower surface, a plurality of elongated wood skids underlying and engaged with selected portions of the lower surface of the plastic platform, said skids being in laterally spaced generally parallel relation to each other and presenting floor engaging, unencumbered planar bottom surfaces, the skids defining sliding supports for said platform of a height and spaced for the accommodation of lift equipment below said platform, and means for fixing the wood skids to the lower surface of said platform, said means for fixing the skids to the platform comprising upwardly opening notches transversely across the upper portions of the wood skids, integral hollow ribs depending from the corresponding selected portions of the lower surface of the platform and completely received within each said skid notch, each rib being elongated and substantially coextensive with the corresponding notch, fasteners engaged through said notch-received ribs and into the skids, the selected portions of the lower surface of the platform, other than said ribs, presenting planar surfaces coextensive with and engaged flat against the tops of the skids said molded plastic platform being capable of slight flexure so as to comform to a superimposed load upon the application of banding straps about the platform and load.
Claim 3
Dependent Claim
35 words
The pallet of claim 1 wherein each wood skid includes more than one of the upwardly opening rib-receiving notches transversely thereacross, the notches in each skid being longitudinally spaced along the length of the skid.
Claim 4
Dependent Claim
89 words
The pallet of claim 2 wherein the wood skids are oriented toward opposed edge portions of the platform with each skid including an outer side directed toward the adjacent edge portion of the platform and an inner side directed toward the center of the platform, integral retaining ribs depending from the lower surface of the platform and positioned along the inner and outer sides of each of said skids for a stabilization and retention of the skid, said retaining ribs terminating above the bottom surface of the associated skid.
Claim 5
Dependent Claim
24 words
The pallet of claim 3 including integrally formed strengthening gussets extending between each outer side rib and the platform thereabove and immediately outward thereof.
Claim 6
Dependent Claim
47 words
The pallet of claim 4 including a first set of opposed band-receiving seats defined in the peripheral edge of the platform, and a second set of opposed band-receiving seats defined in the peripheral edge of the platform at approximately 90° to the first set of band-receiving seats.
Claim 7
Dependent Claim
21 words
The pallet of claim 5 including an integral retaining flange projecting upwardly from the upper load-receiving surface peripherally about said platform.
Claim 8
Dependent Claim
54 words
The pallet of claim 6 wherein four skids are utilized, said skids being orientated in two laterally spaced aligned pairs of skids with the skids in each pair being longitudinally aligned, the adjoining inner ends of the skids of each pair being spaced from each other for the accommodation of a banding strap therebetween.
Claim 9
Dependent Claim
26 words

Dependent Claim
21 words
The pallet of claim 4 including an integral retaining flange projecting upwardly from the upper load-receiving surface peripherally about said platform.
Claim 13
Dependent Claim
28 words
The pallet of claim 11 wherein each skid, along the inner side thereof, includes a portion thereof projecting laterally to underly and protect the associated inner side rib.
Claim 14
Dependent Claim
