Abstract

An article of footwear includes a sole assembly that has a bladder element with a first outer surface and a second outer surface opposite the first surface. A guide component is fused to one of the outer surfaces. The guide component has at least one groove extending laterally across the guide component. The at least one groove is configured to receive and guide at least one elongated member such that the elongated member is movable lengthwise when positioned in the at least one groove. A method of manufacturing a sole assembly for an article of footwear includes fusing the guide component to one of the first outer surface and the second outer surface of the bladder element.

First claim

What is claimed is:

1. An article of footwear comprising:
a sole assembly having:
a bladder element with a first outer surface, a second outer surface opposite the first outer surface, and side surfaces extending from the first outer surface to the second outer surface;
a guide component with a bottom portion fused to one of the first outer surface or the second outer surface and side portions fused to the side surfaces; wherein the guide component has multiple grooves extending laterally across the bottom portion of the guide component; wherein the multiple grooves are configured to receive and guide multiple elongated members such that the multiple elongated members are movable lengthwise when positioned in the multiple grooves; and

wherein at least one of the side portions includes a finger on which two adjacent ones of the multiple grooves merge into a merged groove.

2. The article of footwear of claim 1 , wherein the guide component has at least one retaining bar that extends across the merged groove.

3. The article of footwear of claim 1 , wherein the multiple grooves are three-sided channels.

4. The article of footwear of claim 1 , wherein the sole assembly includes an outsole secured to the guide component such that the multiple grooves are partially enclosed by the outsole.

5. The article of footwear of claim 1 , in combination with the multiple elongated members, and further comprising:
an upper secured to the sole assembly;
wherein the upper has at least one anchoring feature that receives the multiple elongated members such that the multiple elongated members extend through the multiple grooves and through the at least one anchoring feature, the bladder element thereby being biased toward the upper by force of the multiple elongated members against the guide component.

6. The article of footwear of claim 5 , wherein the at least one anchoring feature includes an anchoring element secured to a body of the upper at a heel region of the upper; and wherein at least one of the multiple elongated members extends through an opening in the anchoring element and is retained between the anchoring element and the body of the upper.

7. The article of footwear of claim 5 , wherein the at least one anchoring feature is at least one eyelet in the upper; and wherein the at least one of the multiple elongated members extends through the at least one eyelet.

8. The article of footwear of claim 7 , further comprising:
at least one guide secured to the upper; and wherein the at least one of the multiple elongated members extends through the at least one guide between the at least one of the multiple grooves and the at least one eyelet.

9. The article of footwear of claim 1 , wherein the side portions include a lateral side portion and a medial side portion; wherein each of the side portions includes a finger with a merged groove and a retaining bar that extends across the merged groove to retain the multiple elongated members when the multiple elongated members are positioned in the merged groove.

10. The article of footwear of claim 1 , wherein the guide component has apertures between adjacent ones of the multiple grooves.

11. The article of footwear of claim 1 , wherein the guide component is formed from a polymeric material.

12. The article of footwear of claim 1 , further comprising:
an upper;
an outsole;
wherein the sole assembly is secured to the upper so that the first outer surface of the bladder element faces toward the upper and the second outer surface of the bladder element faces toward the outsole;
wherein the outsole is secured to the bottom portion of the guide component to enclose the multiple grooves along the bottom portion;
wherein the upper is configured to be secured to the multiple elongated members so that the multiple elongated members bias the bladder element toward the upper when the multiple elongated members are positioned in the multiple grooves.

13. The article of footwear of claim 1 , wherein the guide component is a unitary, one-piece component.

14. The article of footwear of claim 1 , wherein:
the side portions include a medial side portion and a lateral side portion which extend upwardly from the bottom portion; and
the multiple grooves continue upward from the bottom portion along each of the medial side portion and the lateral side portion.

15. The article of footwear of claim 14 , wherein:
the medial side portion and the lateral side portion each include a plurality of separated fingers.

16. The article of footwear of claim 15 , wherein the plurality of separated fingers are angled forward toward a front end of the guide component.

17. The article of footwear of claim 15 , wherein the plurality of separated fingers of the medial side portion and the plurality of separated fingers of the lateral side portion each include a finger on which two adjacent ones of the multiple grooves merge into a merged groove.
