Footwear upper with dynamic and lock-out regions
An article of apparel includes a base layer and an auxetic layer coupled to the base layer. The auxetic layer includes an auxetic structure defining a repeating pattern of shapes, with each of the shapes defined by perimeter walls and an interior recess. The auxetic layer includes a first region and a second region. Each interior recess in the first region provides a void exposing the base layer, and each interior recess in the second region is at least partially filled with a recess material.
1. An article of apparel comprising:
a base layer; and
an auxetic layer coupled to the base layer, the auxetic layer comprising an auxetic structure defining a repeating pattern of perimeter walls and interior recesses, the auxetic layer including a first region and a second region, wherein each interior recess in the first region provides a void exposing the base layer, and wherein each interior recess in the second region is at least partially filled with a recess material.
2. The article of apparel of claim 1 wherein the base layer is a four way stretch material.
3. The article of apparel of claim 1 wherein the recess material is unitary in composition with the perimeter walls.
4. The article of apparel of claim 1 wherein the article of apparel is an article of footwear.
5. The article of apparel of claim 1 wherein the perimeter walls include a top surface and an opposite bottom surface, wherein the bottom surface faces the base layer, and wherein the recess material covers the base layer in each interior recess of the second region without extending to the top surface of the perimeter walls.
6. The article of apparel of claim 1 wherein the perimeter walls of the auxetic structure comprise a plurality of interconnected wall segments that form a repeating pattern of reentrant polygonal shapes.
7. The article of apparel of claim 1 wherein the auxetic structure has a Poisson's ratio of substantially zero or less than zero.
8. An article of apparel comprising:
a base layer; and
an auxetic structure coupled to the base layer, the auxetic structure including a plurality of interconnected members forming an array of cell units, each of the plurality of interconnected members forming cell walls with interior recesses defined within the cell walls, the array of cell units including at least one dynamic region wherein the interior recesses expose the base layer and at least one lockout region wherein a fill in the interior recesses covers the base layer.
9. The article of apparel of claim 8 wherein the base layer is a four way stretch material.
10. The article of apparel of claim 8 wherein the fill is unitary in composition with the interconnected members.
11. The article of apparel of claim 8 wherein the article of apparel is an article of footwear.
12. The article of apparel of claim 8 wherein the interconnected members include a top surface and an opposite bottom surface, wherein the bottom surface faces the base layer, and wherein the fill covers the base layer in each interior recess of the lockout region without extending to the top surface of the cell walls.
13. The article of apparel of claim 8 wherein the interconnected members of the auxetic structure comprise a plurality of wall segments that form a repeating pattern of reentrant polygonal shapes.
14. The article of apparel of claim 8 wherein the auxetic structure has a Poisson's ratio of substantially zero or less than zero.
15. An article of footwear comprising:
a sole; and
an upper connected to the sole, the upper including
a base layer; and
an auxetic layer connected to the base layer, the auxetic layer comprising an auxetic structure defining a repeating pattern of shapes, each of the shapes defined by perimeter walls with an interior recess provided within each shape, the auxetic layer including a first region and a second region, wherein each interior recess in the first region provides a void exposing the base layer, and wherein each interior recess in the second region is at least partially filled with a recess material.
16. The article of footwear of claim 15 wherein the perimeter walls define a top surface and an opposite bottom surface, wherein the bottom surface faces the base layer, and wherein the recess material covers the base layer in each interior recess without extending to the top surface of the perimeter walls in the second region.
17. The article of footwear of claim 15 wherein the perimeter walls are comprised of a wall material, wherein the wall material is integrally formed with the recess material in the second region.
18. The article of footwear of claim 15 , the second region is provided in a toe region and a transition region of the upper extending along the perimeter of the sole.
19. The article of footwear of claim 15 wherein the repeating pattern of shapes is a repeating pattern of polygonal reentrant shapes and the auxetic structure has a Poisson's ratio of substantially zero or less than zero.
20. The article of footwear of claim 15 wherein the base layer comprises a four way stretch material.
