Abstract
A cushioning and impact absorbing pad system with a surface layer of thickness t, and an elastomeric sub-surface structure of height h. The sub-surface structure comprises an array of elastomeric columns wherein each column has a frustoconical column wall surrounding a central void. The cross-sectional thickness of the column wall increases from the first end to the enclosed second end by a percentage within a range of greater than 125% and less than 140%. Column walls are tapered with draft angles in the range of greater than 6 degrees and less than 10 degrees.
Claims20
A resilient pad system comprising at least one pad, the pad comprising a plurality of supporting resilient substructure hollow columns, each such column having a column wall with a cross-sectional thickness, the wall tapered from a first end to an enclosed second end;
- the column wall surrounding a central void, the void extending from the first end to the enclosed second end of the column;
- wherein the cross-sectional thickness of the column wall increases from the first end to the enclosed second end by a percentage within a range of greater than 125% and less than 140%.
A resilient pad system comprising at least one pad, the pad comprising a plurality of supporting resilient substructure hollow columns, each such column having a column wall tapered, both inside and out, from a first end to an enclosed second end;
- the column wall surrounding a central void, the void extending from the first end to the enclosed second end of the column;
- wherein the column wall is tapered with an outside wall draft angle greater than 6 degrees and less than 10 degrees, and an inside wall draft angle greater than 6 degrees and less than 10 degrees.
A resilient pad system comprising at least one pad, the pad comprising a surface layer and a plurality of supporting resilient substructure hollow columns arrayed beneath the surface layer having a thickness t, each such column having a central axis and a column wall, the column wall surrounding a central void, the void extending from a first end to an enclosed second end of the column;
- wherein the pad system has a cross-sectional pad thickness T, each central void defined by the column walls has a relatively uniform height h within the cross-sectional thickness T, and thickness t extends beyond the enclosed end of the central voids within the cross-sectional thickness T, such that T=t+h;
- and the ratio of h:t is greater than 1.3 and less than 3.5.
