Abstract

An article can include a layer disposed on the article, where the layer includes a plurality of materials each having a different hardness than an adjacent material. The plurality of materials is arranged on the article such that a stiffness of the article is gradated along a length of the article from a first portion to a second portion of the article. A stiffness of the second portion is greater than a stiffness of the first portion and the layer has a continuous and even gradation that extends along the entire length of the article. The article comprises a fabric on which the layer is disposed.

First claim

1 . An article comprising:
a layer disposed on the article, wherein the layer includes a plurality of materials each having a different hardness than an adjacent material, wherein the plurality of materials is arranged on the article such that a stiffness of the article is gradated along a length of the article from a first portion to a second portion of the article, wherein a stiffness of the second portion is greater than a stiffness of the first portion, wherein the layer has a continuous and even gradation that extends along the entire length of the article, and wherein the article comprises a fabric on which the layer is disposed.

2 . The article of claim 1 , wherein the layer is a second layer, and the article further comprises a first layer on which the second layer is disposed.

3 . The article of claim 1 , wherein the article further comprises first and second side portions, wherein the plurality of materials is arranged on the article such that stiffnesses of either or both of the first and second side portions is less than the stiffness of the second portion and greater than the stiffness of the first portion.

4 . The article of claim 3 , wherein the plurality of materials includes:
a first material disposed on the first portion of the article, wherein the first material has a first hardness; a second material disposed on the first side portion of the article, wherein the second material has a second hardness; a third material disposed on the second side portion of the article, wherein the third material has a third hardness; and a fourth material disposed on the second portion of the article, wherein the fourth material has a fourth hardness, wherein the first hardness is less than the second hardness, the third hardness, and the fourth hardness, wherein the second hardness is less than the third hardness and the fourth hardness, and wherein the third hardness is less than the fourth hardness.

5 . The article of claim 4 , wherein the first, second, third, and fourth materials have a uniform thickness.

6 . The article of claim 5 , wherein the first hardness of the first portion is within a range of 15 A- 49 A on a Shore A durometer scale, and wherein the fourth hardness of the second portion is within a range of 50 A- 100 A on the Shore A durometer scale.

7 . The article of claim 1 , wherein the layer has a uniform color.

8 . The article of claim 1 , wherein the layer has one or more of a uniform color and uniform texture.

9 . The article of claim 1 , wherein the layer has a uniform thickness.

10 . The article of claim 1 , wherein the plurality of materials includes a first material and a second material disposed on the first portion of the article, wherein the first material has a plurality of spaced-apart first segments and a first hardness, wherein the second material has a plurality of spaced-apart second segments and a second hardness, wherein the second hardness is greater than the first hardness, wherein the first segments and the second segments are arranged in an alternating pattern from a first side of the article to a second side of the article, and wherein each adjacent pair of second segments comprises a first segment disposed therebetween.

11 . The article of claim 1 , wherein the article is an article of apparel.

12 . The article of claim 11 , wherein the article of apparel is an undergarment.

13 . The article of claim 1 , wherein the article is an article of footwear.
