Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
143 words
The combination comprising: a freight container; a plurality of discrete articles of freight in said container, said articles being arranged in at least two adjacent stacks of articles with a generally planar space therebetween bounded on opposite sides by said articles; and expandable honeycomb structure of sheet material substantially filling said space with the sheet material thereof extending transversely across said space, said honeycomb structure being expandable and contractable in a vertical direction; and at least one elongated substantially rigid suspension member at the top portion of said honeycomb structure, pivotally secured thereto about a vertical axis, extending transversely across said space and bearing on the upper surface of articles of said stacks on opposite sides of said space whereby to suspend said honeycomb structure in said space while being swingable to lie within said space and permit said honeycomb structure to contract.
Claim 2
Dependent Claim
143 words
The combination comprising: a freight container; a plurality of discrete articles of freight in said container, said articles being arranged in at least two adjacent stacks of articles with a generally planar space therebetween bounded on opposite sides by said articles; and expandable honeycomb structure of sheet material substantially filling said space with the sheet material thereof extending transversely across said space, said honeycomb structure being expandable and contractable in a vertical direction; and at least one elongated substantially rigid suspension member at the top portion of said honeycomb structure, pivotally secured thereto about a vertical axis, extending transversely across said space and bearing on the upper surface of articles of said stacks on opposite sides of said space whereby to suspend said honeycomb structure in said space while being swingable to lie within said space and permit said honeycomb structure to contract.
Claim 3
Dependent Claim
30 words
The combination of claim 1 including a rigid base member fixed to the top portion of said honeycomb structure, said suspension member being pivotally mounted on said rigid base member.
Claim 4
Dependent Claim
26 words
The combination of claim 2 wherein a plurality of said suspension members are pivoted to said rigid base member spaced along the length of said space.
Claim 5
Dependent Claim
25 words
The combination of claim 2 wherein at least two of said suspension members are pivoted to said rigid base member on a common pivot axis.
Claim 6
Dependent Claim
88 words
An expandable honeycomb structure comprising: a stack of strips of sheet material, the strips of said stack being secured to adjacent strips at spaced and staggered positions whereby said stack may be expanded to define a honeycomb slab having a multiplicity of cells; and elongated substantially rigid suspension member pivoted to an outer strip of said stack and swingable between positions where it lies between the edges of said outer strip, and where it extends transversely of said outer strip and laterally outwardly of the side edges thereof.
Claim 7
Dependent Claim
88 words
An expandable honeycomb structure comprising: a stack of strips of sheet material, the strips of said stack being secured to adjacent strips at spaced and staggered positions whereby said stack may be expanded to define a honeycomb slab having a multiplicity of cells; and elongated substantially rigid suspension member pivoted to an outer strip of said stack and swingable between positions where it lies between the edges of said outer strip, and where it extends transversely of said outer strip and laterally outwardly of the side edges thereof.
Claim 8
Dependent Claim
27 words
A structure as defined in claim 5 including a rigid base member secured to said outer strip, said suspension member being pivotally mounted on said base member.
Claim 9
Dependent Claim
132 words
An expandable honeycomb structure comprising: a stack of strips of sheet material, the strips of said stack being secured to adjacent strips at spaced and staggered positions whereby said stack may be expanded to define a honeycomb slab having a multiplicity of cells; a sheet of foldable material having a portion secured to an outer strip of said stack and extending laterally outwardly of the side edges of said strip; a plurality of parallel score lines extending across said foldable sheet, transversely of said outer strip, in a region of said sheet free of securement to said outer strip, whereby said sheet may be folded along said score lines and secured in folded condition to define a substantially rigid and generally tubular support means extending transversely across and outwardly of said stack.
Claim 10
Dependent Claim
132 words
An expandable honeycomb structure comprising: a stack of strips of sheet material, the strips of said stack being secured to adjacent strips at spaced and staggered positions whereby said stack may be expanded to define a honeycomb slab having a multiplicity of cells; a sheet of foldable material having a portion secured to an outer strip of said stack and extending laterally outwardly of the side edges of said strip; a plurality of parallel score lines extending across said foldable sheet, transversely of said outer strip, in a region of said sheet free of securement to said outer strip, whereby said sheet may be folded along said score lines and secured in folded condition to define a substantially rigid and generally tubular support means extending transversely across and outwardly of said stack.
