Footwear impact distribution
An article of footwear includes a footwear portion including a core including a plurality of plates. A first one of the plurality of plates is hingedly attached, at one or more edges of the first plate, to one or more substantially adjacent other plates in the plurality of plates. Each hinge hingedly attaching an edge of the first plate to another plate joins less than the entire respective hingedly attached edge to a corresponding one of the one or more substantially adjacent other plates and is integrally connected to the first plate.
1. An article of footwear comprising:
a footwear portion including:
a substrate of a first material; and
a core including a plurality of plates, wherein the core is of a second material more rigid than the first material and a first one of the plurality of plates is hingedly attached, at one or more edges of the first plate, to one or more substantially adjacent other plates in the plurality of plates,
wherein each hinge hingedly attaching an edge of the first plate to another plate joins less than the entire respective hingedly attached edge to a corresponding one of the one or more substantially adjacent other plates, displaces the respective edge of the first plate from an edge of the other plate by a distance corresponding to a length of the hinge, and is integrally connected to the first plate and the other plate.
2. The article of claim 1 , wherein the footwear portion comprises an insole.
3. The article of claim 1 , wherein the substrate provides impact protection and is disposed substantially adjacent to the core.
4. The article of claim 3 , wherein the substrate is an elastomeric substrate.
5. The article of claim 3 , wherein the substrate includes two or more layers.
6. The article of claim 3 , wherein the core is secured to the substrate.
7. The article of claim 6 , wherein the core is at least partially embedded within the substrate.
8. The article of claim 7 , wherein the substrate is formed around the core to at least partially enclose the core within the substrate.
9. The article of claim 3 , wherein the substrate includes a pocket adapted to at least partially receive the core and at least partially enclose the core within the substrate.
10. The article of claim 1 , wherein the first plate is hingedly attached to two or more substantially adjacent other plates in the plurality of plates.
11. The article of claim 1 , wherein the first plate is a rigid plate.
12. The article of claim 1 , wherein at least one of the plurality of plates possess elastomeric properties.
13. The article of claim 12 , further comprising an elastomeric substrate disposed substantially adjacent to the core, wherein each of the plurality of plates is more rigid than the elastomeric substrate.
14. The article of claim 1 , wherein each plate in the plurality of plates is joined to at least one other plate in the plurality of plates.
15. The article of claim 1 , wherein the hinge is of the same material as the first plate.
16. The article of claim 1 , wherein the first plate is a hexagonal plate and hingedly connected to at least six other substantially adjacent other plates in the plurality of plates.
17. The article of claim 1 , wherein the first plate is a substantially circular plate.
18. The article of claim 1 , wherein the first plate has a free-form shape.
19. An article comprising:
an insole for footwear, the insole comprising:
a plurality of plates, a first one of the plurality of plates being hingedly attached, at one or more edges of the first plate, to one or more substantially adjacent other plates in the plurality of plates,
wherein each hinge hingedly attaching an edge of the first plate to another plate joins less than the entire respective hingedly attached edge to a corresponding one of the one or more substantially adjacent other plates, displaces the respective edge of the first plate from an edge of the other plate by a distance corresponding to a length of the hinge, and is integrally connected to the first plate and the other plate.
20. The article of claim 19 , further comprising an elastomeric substrate, wherein the at least a portion of the plurality of plates are disposed substantially adjacent to the elastomeric substrate.
21. A method for reinforcing an article of footwear, the method comprising:
securing a plurality of interconnected plates to a portion of the article of footwear, wherein the article of footwear comprises a substrate of a first material, the plurality of interconnected plates are secured to the substrate and are of a second material, a first one of the plurality of plates is hingedly connected, at one or more edges of the first plate by one or more respective hinges, to two or more substantially adjacent other plates in the plurality of plates, wherein each of the one or more hinges joins less than the entire respective hingedly attached edge of the first plate to a corresponding one of the two or more substantially adjacent other plates, displaces the respective edge of the first plate from an edge of the corresponding other plate by a distance corresponding to a length of the hinge, and is integrally connected to the first plate and the corresponding other plate.
