Abstract

An article of footwear with an upper including a ribbon structure is disclosed. The ribbon structure comprises ribbon sections running in at least two different directions. Ribbon sections are connected at nodes. Between nodes portions of ribbon act like links joining the nodes. The links can be arranged in various geometries, including a rectangular grid and a triaxial grid. The ribbon structure may extend the entire length of the article of footwear, and may extend through a forefoot, midfoot and heel.

First claim

The invention claimed is:

1. An article of footwear, comprising:
an upper including a ribbon structure, the ribbon structure comprising:
a first set of ribbon sections oriented substantially in a first direction;
a second set of ribbon sections oriented substantially in a second direction that is perpendicular to the first direction;
a third set of ribbon sections oriented substantially in a third direction that is different from the first direction and the second direction;
a fourth set of ribbon sections oriented substantially in a fourth direction that is perpendicular to the third direction;

the first set of ribbon sections including at least a first ribbon portion and the second set of ribbon sections including at least a second ribbon portion, wherein the first ribbon portion and the second ribbon portion intersect at a node; and
wherein a stitch penetrates the first ribbon portion and the second ribbon portion at the node.

2. The article of footwear according to claim 1 , wherein the ribbon structure comprises a plurality of ribbon portions intersecting one another at a plurality of nodes.

3. The article of footwear according to claim 2 , wherein at each node of the plurality of nodes, two or more ribbon portions of the plurality of ribbon portions are oriented in different directions from one another.

4. The article of footwear according to claim 2 , wherein the ribbon structure is formed by a continuous ribbon arranged into a plurality of parallel layers, including at least a first layer and a second layer, the first layer and the second layer intersecting at the plurality of nodes; and
wherein the first layer corresponds to the first set of ribbon sections and the second layer corresponds to the second set of ribbon sections.

5. The article of footwear according to claim 4 , wherein the plurality of parallel layers further includes a third layer and a fourth layer, the third layer and the second layer intersecting at the plurality of nodes; and
wherein the third layer corresponds to the third set of ribbon sections and the fourth layer corresponds to the fourth set of ribbon sections.

6. The article of footwear according to claim 5 , wherein the third set of ribbon sections and the fourth set of ribbon sections form a rectangular grid; and
wherein the first set of ribbon sections and the second set of ribbon sections form diagonal portions that intersect the rectangular grid.

7. The article of footwear according to claim 6 , wherein the ribbon structure has a pattern comprising repeating units of rectangles formed by the third set of ribbon sections and the fourth set of ribbon sections with X-shaped elements centered within the rectangles formed by the first set of ribbon sections and the second set of ribbon sections.

8. The article of footwear according to claim 7 , wherein the pattern includes four triangular openings formed in gaps between adjacent ribbon sections.

9. The article of footwear according to claim 7 , wherein the pattern extends through a substantial entirety of the upper.

10. The article of footwear according to claim 1 , wherein the ribbon structure extends through a substantial entirety of the upper.

11. An article of footwear, comprising:
an upper including a ribbon structure, the ribbon structure comprising:
a first set of ribbon sections oriented substantially in a first direction;
a second set of ribbon sections oriented substantially in a second direction that is perpendicular to the first direction;
a third set of ribbon sections oriented substantially in a third direction that is different from the first direction and the second direction;
a fourth set of ribbon sections oriented substantially in a fourth direction that is perpendicular to the third direction;

wherein the ribbon structure comprises a plurality of ribbon portions associated with the first set of ribbon sections, the second set of ribbon sections, the third set of ribbon sections, and the fourth set of ribbon sections, the plurality of ribbon portions intersecting one another at a plurality of nodes.

12. The article of footwear according to claim 11 , wherein the plurality of nodes comprises two types of nodes.

13. The article of footwear according to claim 12 , wherein the two types of nodes includes a first type of node formed at locations where ribbon portions of the first set of ribbon sections and ribbon portions of the second set of ribbon sections intersect.

14. The article of footwear according to claim 13 , wherein the two types of nodes further includes a second type of node formed at locations where ribbon portions of the first set of ribbon sections, the second set of ribbon sections, the third set of ribbon sections, and the fourth set of ribbon sections all intersect each other.

15. The article of footwear according to claim 11 , wherein a stitch penetrates the ribbon portions at each node of the plurality of nodes.

16. An article of footwear, comprising:
an upper including a ribbon structure, the ribbon structure comprising:
a first set of ribbon sections oriented substantially in a first direction;
a second set of ribbon sections oriented substantially in a second direction that is perpendicular to the first direction;
a third set of ribbon sections oriented substantially in a third direction that is different from the first direction and the second direction;
a fourth set of ribbon sections oriented substantially in a fourth direction that is perpendicular to the third direction;

wherein, in the presence of a tensioning force applied to the first set of ribbon sections, the second set of ribbon sections are configured to remain in a neutral, non-tensioned configuration.

17. The article of footwear according to claim 16 , wherein a distance between adjacent ribbon sections of the second set of ribbon sections is configured to be reduced in the presence of the tensioning force applied to the first set of ribbon sections.

18. The article of footwear according to claim 16 , wherein in the presence of the tensioning force applied to the first set of ribbon sections, the third set of ribbon sections and the fourth set of ribbon sections are configured to remain in a neutral, non-tensioned configuration.

19. The article of footwear according to claim 16 , wherein the ribbon structure extends through a substantial majority of the upper.

20. The article of footwear according to claim 16 , wherein the ribbon structure comprises a plurality of ribbon portions associated with the first set of ribbon sections, the second set of ribbon sections, the third set of ribbon sections, and the fourth set of ribbon sections, the plurality of ribbon portions intersecting one another at a plurality of nodes.
