Abstract
Abstract A portable airfreight container base panel or other load-bearing panel of hollow core reinforced construction comprising top and bottom sheets interconnected and maintained in parallel relationship by spaced parallel ribs, with the top sheet additionally supported by nonfastened intercostal tubular columns bridging between sheets and maintained in preselected design positions, suited to the specific load requirements of individual applications, by one or more styrofoam retainer sheets or equivalent means apertured to receive and hold the columns in position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
124 words
A load-bearing base panel for incorporation in airfreight containers, load-bearing pallets, vehicle cargo platforms and the like, said panel being of hollow core reinforced construction comprising substantially continuous top and bottom structural sheets interconnected and maintained in parallel relationship by transversely spaced reinforcing members, and intercostal additional support means for the top and bottom sheets comprising a plurality of transversely spaced-apart compression load-bearing columns bridging between said top and bottom sheets and having opposing ends abutted but unfastened to said sheets at selected positions in at least certain of the spaces between such reinforcing members, and positioning means maintained in position by contact with a plurality of such reinforcing members and in turn maintaining the columns in spaced-apart positions in each of said spaces.
Claim 2
Dependent Claim
124 words
A load-bearing base panel for incorporation in airfreight containers, load-bearing pallets, vehicle cargo platforms and the like, said panel being of hollow core reinforced construction comprising substantially continuous top and bottom structural sheets interconnected and maintained in parallel relationship by transversely spaced reinforcing members, and intercostal additional support means for the top and bottom sheets comprising a plurality of transversely spaced-apart compression load-bearing columns bridging between said top and bottom sheets and having opposing ends abutted but unfastened to said sheets at selected positions in at least certain of the spaces between such reinforcing members, and positioning means maintained in position by contact with a plurality of such reinforcing members and in turn maintaining the columns in spaced-apart positions in each of said spaces.
Claim 3
Dependent Claim
13 words
The base panel defined in claim 1, wherein the columns are tubular members.
Claim 4
Dependent Claim
13 words
The base panel defined in claim 2, wherein the tubular members are round.
Claim 5
Dependent Claim
154 words
A load-bearing base panel for incorporation in airfreight containers, load-bearing pallets, vehicle cargo platforms and the like, said panel being of hollow core reinforced construction comprising substantially continuous top and bottom structural sheets interconnected and maintained in parallel relationship by transversely spaced elongated reinforcing ribs, and intercostal additional support means for the top and bottom sheets comprising a plurality of transversely spaced-apart compression load-bearing columns bridging between said top and bottom sheets and having opposing ends bearing against said sheets in unbonded contact therewith at selected positions in at least certain of the spaces between successive ribs, and positioning means maintaining the columns in spaced-apart positions in each of said spaces, said structural sheets comprising metal sheets, and the positioning means in each such space comprising a substantially rigid sheet multiply apertured to receive and hold the columns positionally in the apertures and fixedly positioned in the space between the ribs adjoining such space.
