Abstract

A cushion pad arrangement for protecting a person'"'"'s extremity from compressive and side to side rubbing stresses, as particularly occur at a person'"'"'s shin, ankle and foot as a result of wearing a boot during use, such as a ski boot during skiing. The cushion pads are formed as a sandwich of serially and parallel connected cells arranged between top and bottom layers, which cells and connecting tubes are formed of a somewhat resilient material, and are selectively filled with air, liquid or gel, depending upon the anticipated forces the pad is intended to cushion, the cushion pads to provide an increasing force dispersion with increasing pressures.

Claims

1. A cushion pad, comprising a plurality of fluid containing resilient cells or compartments as a dispersion array formed in a material;

tube means for allowing fluid flow between cells or compartments in said dispersion array of cells, where each dispersion array comprises two or more cells with a first cell, wherein, for said first cell in each said dispersion array, at least one proximal cell is provided, with such proximal cell being a cell that is closer to the first cell than any other cell, and for each first cell at least one distal cell exists in each said dispersion array, a distal cell being any cell that is not a proximal cell; and

the first cell in each dispersion array is connected by tube means to at least one distal cell.

2. A cushion pad as recited in claim 1, wherein the cells or compartments are arranged as a sandwich between flat sheets of a plastic material.

3. A cushion pad as recited in claim 1, further including means for maintaining the cushion pad over an area of the human body where stress concentrations are anticipated.

4. A cushion pad as recited in claim 3, wherein the means for maintaining a cushion pad over the area is a sock surface for covering a person'"'"'s foot with sections of VELCRO®

type fasteners fixed to opposing surfaces of said sock surface and cushion pad.

5. A cushion pad as recited in claim 4, wherein the sock is formed to function as a VELCRO®

type mat.

6. The cushion pad of claim 1, wherein the first cell in each dispersion array is connected by the means to a plurality of distal cells.

7. The cushion pad of claim 6, where the first cell of each dispersion array is connected to four equidistant distal cells forming a star.

8. A cushion pad as recited in claim 7, wherein a section is made up of a side by side arrangement dispersion arrays formed as stars with equal intervals therebetween.

9. A cushion pad as recited in claim 8, further including closed cells or compartments, each arranged between adjacent straight radiating arms.

10. A cushion pad as recited in claim 9, wherein the radiating arms are made of serially connected cells or compartments of different volumes.

11. The cushion pad of claim 1, further including, with each dispersion array one or more middle cells that are each connected by tube means to two distal cells.

12. A cushion pad as recited in claim 11, wherein the dispersion array of cells or compartments are arranged into a closed hexagon.

13. A cushion pad as recited in claim 11 further including the first cell or compartment linked by tube means to one of the middle cells or compartments.

14. A cushion pad as recited in claim 13, wherein a partial ring of distal cells is arranged within a closed hexagon, partially encircling the first cell or compartment.

15. A cushion pad as recited in claim 14, wherein the hexagonal ring and partial ring are formed of cells or compartments of different volumes.

16. The cushion pad of claim 11, further comprising, with each dispersion array one or more end cells, each connected by tube means to one distal cell.

17. The cushion pad of claim 16, wherein each dispersion array is U-shaped, the cells of each U-shaped dispersion array being interdigitated with the cells of another U-shaped dispersion array.

18. A cushion pad as recited in claim 17, wherein the U-shaped segments and straight segments are formed of serially connected cells or compartments of different volumes.

19. The cushion pad of claim 1, further including, with each tube means, a linking cell arranged between the cells that are connected by said tube means.

20. The cushion pad of claim 1, wherein the cells contain fluid, water, or air.

21. The cushion pad of claim 1, wherein the material is resilient.

22. The cushion pad of claim 21, wherein the material is latex or gum rubber.

23. The cushion pad of claim 1, wherein a plurality of proximal cells or compartments are arranged adjacent to the first cell or compartment, the proximal cells or compartments being equidistant to said first cell or compartment and connected thereto by the tube means.

24. A protective food and shin cushion device comprising, a sock or bootie for wear over a person'"'"'s foot and extending to cover their shin area;

a cushion pad means for arrangement between said sock or bootie and a boot worn on that foot having a plurality of equally spaced cells or compartments that taper from a greater to lesser height from the edge of a shock zone or area to be covered to the surface of the sock or bootie; and

means for attaching said cushion pad means to said sock or bootie.

25. A protective foot and shin cushion device as recited in claim 24, wherein the sock or bootie is formed from a soft, flexible material such as latex.

26. A protective foot and shin cushion device as recited in claim 24, wherein the cushion pad means are formed as separate pads for attachment onto the sock or bootie surface.

27. A protective foot and shin cushion device as recited in claim 26, wherein the cushion pads are formed as a sandwich of somewhat flexible cells or compartments that are filled with air, liquid or gel and are individual connected together in series or parallel into sections by tube means, which said sections of cells or compartments are spaced equally from one another and are arranged between top and bottom layers for releasable attachment to said sock or bootie surface.

28. A protective foot and shin cushion device as recited in claim 27, wherein the cells or compartments arranged in sections receive a latex material therearound that sets up to provide further cushioning and forms the top and bottom layers.

29. A protective foot and shin cushion device as recited in claim 28 wherein the cells or compartments in a same or adjacent section are of different volumes.
