Board with cellular structure

Claim 2

In a load carrying pallet having an interior core of cellular structure including a plurality of cells located adjacent one another the improvement comprising, each pair of adjacent cells having a common side wall, each of said side walls of the cells having upper and lower ends, said upper and lower ends of the cells being covered and hermetically sealed by upper and lower covering layers, respectively, each of said side walls of the cells being elastically deformable so as to yield resiliently when a load is applied thereto but recover its original shape when the load is removed therefrom, and said covered and sealed cells thereby forming a plurality of deformable air chambers which function to absorb and transmit to adjacent cells, shocks and loads directed to said upper and lower covering layers.

Claim 3

The load carrying pallet of claim 1 wherein the cells are integrally formed so as to be a homogenous core structure.

Claim 4

In a load carrying pallet having an interior core of cellular structure including a plurality of cells located adjacent one another the improvement comprising, each pair of adjacent cells having a common side wall, each of said side walls of the cells being elastically deformable so as to yield resiliently when a load is applied thereto but recovers its original shape when the load is removed therefrom and having upper and lower ends, said upper and lower ends of the cells being covered and hermetically sealed by upper and lower covering layers, respectively, said covered and sealed cells forming a plurality of deformable air chambers which function to absorb and transmit to adjacent cells, shock and loads directed to said upper and lower covering layers, support brackets mounted to said lower covering layer, each of said support brackets extending parallel with respect to one another, a pair of spaced opening in each of said support brackets, each pair of spaced openings of one support bracket being axially aligned with the pair of spaced openings in the other support brackets whereby said support brackets serve to space said lower covering layer from a support surface, a plurality of first drain holes through the core and through said upper and lower covering layers, and each of said support brackets including second drain holes therethrough, said second drain holes communicating with said first drain holes whereby fluid collected along said upper covering layer of the load carrying pallet will be discharged through said second drain holes of said support brackets.

Claim 5

In a load carrying pallet having an interior core of cellular structure including a plurality of cells located adjacent one another the improvement comprising, each pair of adjacent cells having a common side wall, each of said side walls of the cells being elastically deformable so as to yield resiliently when a load is applied thereto but recovers its original shape when the load is removed therefrom and having upper and lower ends, said upper and lower ends of the cells being covered and hermetically sealed by upper and lower covering layers, respectively, said covered and sealed cells forming a plurality of deformable air chambers which function to absorb and transmit to adjacent cells, shock and loads directed to said upper and lower covering layers, support brackets mounted to said lower covering layer, each of said support brackets extending parallel with respect to one another, a pair of spaced opening in each of said support brackets, each pair of spaced openings of one support bracket being axially aligned with the pair of spaced openings in the other support brackets whereby said support brackets serve to space said lower covering layer from a support surface, a plurality of first drain holes through the core and through said upper and lower covering layers, and each of said support brackets including second drain holes therethrough, said second drain holes communicating with said first drain holes whereby fluid collected along said upper covering layer of the load carrying pallet will be discharged through said second drain holes of said support brackets.

Claim 6

In a load carrying composite board having an interior core of cellular structure including a plurality of cells located adjacent one another the improvement comprising, each pair of adjacent cells having a common side wall, each of said side walls of the cells having upper and lower ends, the cells being integrally formed so as to be a homogenous core structure, said upper and lower ends of the core structure being covered with each cell hermetically sealed by upper and lower covering layers, respectively, each of said walls of the cells being elastically deformable so as to yield resiliently when a load is applied thereto but recover its original shape when the load is removed therefrom, and said covered and sealed core structure thereby forming a plurality of deformable air chambers which function to absorb and transmit to adjacent cells, shocks and loads directed to said upper and lower covering layers.

Claim 7

In a load carrying composite board having an interior core of cellular structure including a plurality of cells located adjacent one another the improvement comprising, each pair of adjacent cells having a common side wall, each of said side walls of the cells having upper and lower ends, the cells being integrally formed so as to be a homogenous core structure, said upper and lower ends of the core structure being covered with each cell hermetically sealed by upper and lower covering layers, respectively, each of said walls of the cells being elastically deformable so as to yield resiliently when a load is applied thereto but recover its original shape when the load is removed therefrom, and said covered and sealed core structure thereby forming a plurality of deformable air chambers which function to absorb and transmit to adjacent cells, shocks and loads directed to said upper and lower covering layers.
