Abstract

An article of footwear may have an upper and a sole structure secured to the upper. The upper includes an illuminable panel and a plurality of strands positioned to extend adjacent and parallel to the illuminable panel. The illuminable panel has a surface with a covered area and an exposed area. The covered area includes a substantially opaque covering, and the exposed area is at least partially visible from the exterior of the footwear. The strands are located to correspond with the exposed area of the illuminable panel. Light from the exposed area of the illuminable panel may enhance, highlight, or otherwise increase the visibility of the strands or areas of the upper that include the strands.

Claims

1. An article of footwear having an upper and a sole structure secured to the upper, the upper comprising:

an illuminating panel that emits light, the illuminating panel having a first surface and an opposite second surface, the first surface being oriented to face toward an exterior of the footwear, and the second surface being oriented to face toward an interior of the footwear, the first surface having a covered area and an exposed area, the covered area including a substantially opaque covering disposed on the first surface of the illuminating panel and blocking light emitted by the illuminating panel, and the exposed area being at least partially visible from the exterior of the footwear; and

a first plurality of strands positioned to extend adjacent and parallel to the illuminating panel, the strands being located to correspond with the exposed area of the illuminating panel;

wherein the plurality of strands are disposed on an opposite side of the first surface as the substantially opaque covering.

2. The article of footwear recited in claim 1, wherein the illuminating panel is an electroluminescent panel.

3. The article of footwear recited in claim 1, wherein the strands resist stretch of the upper.

4. The article of footwear recited in claim 1, further including an interior layer forming at least a portion of the upper of the article of footwear;

wherein the interior layer is disposed in contact with the second surface of the illuminating panel; and

wherein the strands are located between the illuminating panel and the interior layer.

5. The article of footwear recited in claim 1, wherein an at least semi-transparent cover layer is secured to the first surface of the illuminating panel.

6. The article of footwear recited in claim 1, further including a second plurality of strands located adjacent to the first surface of the illuminating panel.

7. The article of footwear recited in claim 1, wherein the exposed area includes a plurality of linear portions extending between a lace region of the upper and a region where the sole structure is joined to the upper.

8. The article of footwear recited in claim 1, wherein portions of the illuminating panel that contact the strands protrude outward to form protrusions on the first surface of the illuminating panel.

9. The article of footwear recited in claim 8, further including a cover layer extending adjacent the first surface of the illuminating panel and forming at least a portion of an exterior surface of the upper of the article of footwear;

wherein the protrusions on the first surface of the illuminating panel project outward forming protrusions on the exterior surface of the cover layer.

10. An article of footwear having an upper and a sole structure secured to the upper, the upper comprising:

an illuminating panel that emits light, the illuminating panel having a surface with a covered area and an exposed area, the covered area including a substantially opaque covering on the surface of the illuminating panel and blocking light emitted by the illuminating panel, and the exposed area being at least partially visible from an exterior of the footwear, the exposed area including a plurality of linear portions extending from a lace region of the upper to a region where the sole structure is joined to the upper;

a cover layer extending adjacent to the surface of the illuminating panel and forming at least a portion of an exterior surface of the upper, the cover layer being formed from an at least semi-transparent material; and

a plurality of strands located in the plurality of linear portions of the exposed area;

wherein the plurality of strands are disposed on an opposite side of the surface of the illuminating panel as the substantially opaque covering.

11. The article of footwear recited in claim 10, wherein the illuminating panel is an electroluminescent panel.

12. The article of footwear recited in claim 10, wherein the surface of the illuminating panel is a first surface;

wherein the illuminating panel includes a second surface opposite the first surface; and

wherein the strands contact the second surface opposite the exposed area of the the first surface of the illuminating panel.

13. The article of footwear recited in claim 12, wherein portions of the illuminating panel that contact the strands protrude outward forming protruding panel portions, and wherein portions of the cover layer that contact the protruding panel portions protrude outward to form protrusions on the exterior surface of the upper.

14. The article of footwear recited in claim 10, wherein at least one of the strands has a first portion located in the exposed area of the illuminating panel and a second portion extending beyond the exposed area of the illuminating panel.

15. An article of footwear having an upper and a sole structure secured to the upper, the upper comprising:

a lace region having a plurality of lace-receiving elements;

a lower region where the sole structure is secured to the upper; and

an illuminating panel that emits light, the illuminating panel at least partially located between the lace region and the lower region, the illuminating panel including a covered area including a substantially opaque covering blocking light emitted by the illuminating panel and defining an exposed area forming a plurality of substantially linear exposed areas extending between the lace region and the lower region; and

a plurality of strands positioned adjacent to the illuminating panel and being respectively located in the linear exposed areas of the illuminating panel;

wherein the plurality of strands are disposed on an opposite side of the illuminating panel as the substantially opaque covering.

16. The article of footwear recited in claim 15, wherein the illuminating panel is an electroluminescent panel.

17. The article of footwear recited in claim 15, wherein at least one of the strands has a first portion located in at least one of the substantially linear exposed areas of the illuminating panel and a second portion extending beyond the corresponding substantially linear exposed area of the illuminating panel.

18. The article of footwear recited in claim 15, wherein the strands resist stretch of the upper.

19. The article of footwear recited in claim 15, wherein the illuminating panel has a first surface and an opposite second surface, the first surface being oriented to face toward an exterior of the footwear, and the second surface being oriented to face toward an interior of the footwear;

wherein the strands contact the second surface opposite the exposed area of the first surface of the illuminating panel; and

wherein portions of the illuminating panel that contact the strands protrude outward forming protruding panel portions.

20. The article of footwear recited in claim 15, wherein a power source is at least partially embedded within the upper and electrically-joined to the illuminating panel.
