Abstract
Abstract An expandable honeycomb structure, of corrugated paper board, is suspended between a load and an adjacent surface in a freight carrier, to fill the space and prevent load shifting. Transverse rigid members in certain of the cells limits their horizontal contraction and prevents the honeycomb structure from sagging unduly.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
157 words
The combination comprising: a freight container; a plurality of discrete articles of freight in said container, said articles being arranged in at least one stack of articles with a generally planar space between said stack and an adjacent vertical surface; an 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; means at the top of said honeycomb structure, supported adjacent the top of said stack of articles to suspend said structure between said stack and said adjacent vertical surface; said honeycomb structure defining a multiplicity of cells having foldably joined bounding walls whereby said cells may be expanded to horizontally elongated shape or to vertically elongated shape; and substantially rigid means in certain of said cElls, extending horizontally therein and bearing against opposite sides thereof to limit horizontal contraction and vertical elongation of said cells.
Claim 2
Dependent Claim
157 words
The combination comprising: a freight container; a plurality of discrete articles of freight in said container, said articles being arranged in at least one stack of articles with a generally planar space between said stack and an adjacent vertical surface; an 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; means at the top of said honeycomb structure, supported adjacent the top of said stack of articles to suspend said structure between said stack and said adjacent vertical surface; said honeycomb structure defining a multiplicity of cells having foldably joined bounding walls whereby said cells may be expanded to horizontally elongated shape or to vertically elongated shape; and substantially rigid means in certain of said cElls, extending horizontally therein and bearing against opposite sides thereof to limit horizontal contraction and vertical elongation of said cells.
Claim 3
Dependent Claim
21 words
The combination defined in claim 1 wherein said rigid means each comprises a sheet of material selectively removable from said cells.
Claim 4
Dependent Claim
44 words
The combination defined in claim 1 wherein said rigid means each comprises a sheet of material secured at only one side to the corresponding side of its cell whereby said honeycomb structure may be collapsed in a vertical direction without removing said rigid means.
Claim 5
Dependent Claim
91 words
An expandable honeycomb structure comprising: a stack of strips of readily foldable sheet material, the strips of said stack being foldably 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; elongated substantially rigid members in certain of said cells, each member being of less length than the collapsed length of its cell, whereby to engage opposite sides of said cell when said structure is expanded and thereby limit the extent of expansion of said structure.
Claim 6
Dependent Claim
91 words
An expandable honeycomb structure comprising: a stack of strips of readily foldable sheet material, the strips of said stack being foldably 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; elongated substantially rigid members in certain of said cells, each member being of less length than the collapsed length of its cell, whereby to engage opposite sides of said cell when said structure is expanded and thereby limit the extent of expansion of said structure.
Claim 7
Dependent Claim
26 words
A structure as defined in claim 4 wherein said rigid members are loose in their cells and readily removable therefrom for positioning in different selected cells.
Claim 8
Dependent Claim
31 words
A structure as defined in claim 4 wherein each of said rigid members is secured, at one end, to the adjacent end of its cell adjacent one of said spaced positions.
