Abstract

A cushion (15, 25 27, 51, 73) comprised of at least one chamber (52-55, 75a-h) comprised of a barrier material, said barrier material comprised of an elastomer, said elastomer being at least semi-permeable to at least a first reactant compound, a second reactant compound disposed within said at least one chamber, wherein said first reactant compound and said second reactant compound react to form a resultant compound, and wherein a rate of diffusion of said resultant compound through said barrier material is less than a rate of diffusion of said first reactant compound through said barrier material. An article of footwear including a cushion, said cushion comprised of at least one chamber comprised of a barrier material, at least a first and a second solid or liquid reactant compounds disposed within said at least one chamber, wherein said first reactant compound and said second reactant compound react to form a resultant gaseous compound.

Claims (28)

1. A cushion comprised of at least one chamber comprised of a barrier material, said barrier material comprised of an elastomer, said elastomer being at least semi-permeable to at least a first reactant compound, a second reactant compound disposed within said at least one chamber, wherein said first reactant compound and said second reactant compound interact to form a resultant compound, and wherein a rate of diffusion of said resultant compound through said barrier material is less than a rate of diffusion of said first reactant compound through said barrier material.
2. The cushion of claim 1 further comprising foam encapsulation of said chamber.
3. The cushion of claim 1 further comprising a mechanical cushioning member disposed within said chamber.
4. The cushion of claim 1 further comprising multiple chambers.
5. The cushion of claim 4 wherein at least several of said multiple chambers are interconnected.
6. The cushion of claim 1 wherein said first reactant compound comprises a gas, a liquid or mixtures thereof.
7. The cushion of claim 1 wherein said second reactant compound is a solid.
8. The cushion of claim 1 wherein said resultant compound comprises at least one gas.
9. The cushion of claim 1 wherein said resultant compound comprises a foam.
10. The cushion of claim 1 wherein said at least one chamber is pressurized to greater than about 14.7 psi. gauge pressure.
11. The cushion of claim 1 wherein said resultant compound comprises CO2.
12. The cushion of claim 1 wherein said resultant compound comprises O2.
13. The cushion of claim 1 wherein said resultant compound comprises N2.
14. The cushion of claim 1 wherein said first reactant compound comprises a gas or liquid.
15. The cushion of claim 1 wherein said second reactant compound comprises a nitrogen containing compound.
16. The cushion of claim 1 wherein said first reactant compound is provided within said chamber.
17. The cushion of claim 1 wherein at least a portion of said first reactant compound diffuses into said chamber from outside said cushion.
18. The cushion of claim 1 wherein said first reactant compound comprises a catalyst or solubilizing agent facilitating the formation of said resultant compound.
19. The cushion of claim 18 wherein said first reactant compound comprises water.
20. A method to maintain inflation of a cushion of an article of footwear comprising forming a sealed chamber comprised of an elastomeric material within said article of footwear and combining within said chamber a first reactant and a second reactant such that said first and second reactants create an inflatant.
21. An article of footwear including a cushion, said cushion comprising at least one sealed elastomeric chamber, said chamber including a reactant material and a reactant gas, wherein said reactant material and said reactant gas undergo a reaction to form an inflatant, and wherein a rate of said reaction is equal to or greater than a rate of diffusion of said inflatant through said sealed elastomeric chamber.
22. The article of footwear of claim 21 wherein said reactant gas is at least partially mobile through said sealed elastomeric chamber.
23. The article of footwear of claim 22 wherein said sealed elastomeric chamber is provided with a path for diffusion of said reactant gas into said chamber.
24. An article of footwear including a cushion, said cushion comprised of at least one chamber comprised of a barrier material, at least a first and a second solid or liquid reactant compounds disposed within said at least one chamber, wherein said first reactant compound and said second reactant compound interact to form a resultant gaseous compound.
25. An article of footwear including a cushion, said cushion comprised of at least one chamber comprised of a barrier material, at least a first and a second solid or liquid reactant compound disposed within said at least one chamber, wherein said first reactant compound and said second reactant compound react to form a resultant gaseous compound, said cushion having "X"
multiple chambers and having less than "X" chambers including said reactant compounds, wherein a means for gas diffusion between a reactant compound containing chamber and a chamber containing no reactive compounds is provided.
26. The article of claim 25, wherein said means for gas diffusion comprises one way valves.
27. The article of claim 25 wherein said means for gas diffusion comprises at least one embedded fiber.
28. An article of footwear including a cushion comprised of at least one chamber comprised of a barrier material, said barrier material comprised of an elastomer, said elastomer being at least semi-permeable to a mobile gas, a reactant compound disposed within said at least one chamber, wherein said mobile gas and said reactant compound interact to form a captive gas, and wherein a rate of diffusion of said captive gas through said barrier material is less than the rate of diffusion of said mobile gas through said barrier material.
