Abstract

In one embodiment, an article of footwear including an upper is described. The upper includes a braid body and at least one component. The braid body includes at least one braided layer. A reinforcement element is attached to the braid body along a connection area using a connecting stitch. The component is attached to the braid body at the connection area using a zigzag stitch including a thread that passes through the component at a first location and passes through the reinforcement element and the braid body at a second location. The second location extends beyond the connecting stitch attaching the reinforcement element to the braid body.

First claim

The invention claimed is:

1. An article of footwear, comprising:
an upper including a braid body and at least one component, wherein the braid body comprises at least one braided layer;
a connection area where edges of the braid body and the component are abutting;
a reinforcement element attached to only an inner surface of the braid body along the connection area adjacent to an inner surface of the component, such that the reinforcement element covers the inner surface of the braid body without covering the inner surface of the component;
a connecting stitch extending through the reinforcement element and the at least one braided layer to an outer surface of the braid body opposite the inner surface to attach the reinforcement element to the inner surface of the braid body; and
a zigzag stitch comprising a thread that passes through the inner surface of only the component at a first location and passes through both of the reinforcement element and the braid body at a second location to attach the component to the braid body at the connection area, wherein the second location is in a direction from the component that is laterally beyond the connecting stitch attaching the reinforcement element to the inner surface of the braid body;
wherein the thread of the zigzag stitch extends over at least one loop of the connecting stitch attaching the reinforcement element to the inner surface of the braid body; and
wherein the edges of the braid body and the component are abutting along the connection area such that the braid body and the component are arranged edge to edge.

2. The article of footwear according to claim 1 , further comprising a sole assembly.

3. The article of footwear according to claim 1 , wherein the connecting stitch comprises two rows of approximately parallel stitches along the connection area.

4. The article of footwear according to claim 3 , wherein at least one loop of the two rows of approximately parallel stitches is disposed between the thread of the zigzag stitch and an outer surface of the reinforcement element.

5. The article of footwear according to claim 1 , wherein an outer edge of the component abuts the braid body along each of a forward edge, a lateral instep edge, and a medial instep edge in a throat area of the upper.

6. The article of footwear according to claim 1 , wherein the component is a lace eyelet element; and
wherein the connection area includes a throat area of the braid body.

7. The article of footwear according to claim 1 , wherein the component is a heel cushioning element; and
wherein the connection area includes a heel area of the braid body.

8. The article of footwear according to claim 1 , further comprising a seam cover element disposed over a portion of the braid body and a portion of the component along the connection area.

9. An article of footwear, comprising:
a braided upper including a throat area and a heel area;
a component including a lace eyelet element and a heel cushioning element;
a connection area where edges of the braided upper and the component are abutting, wherein the connection area includes the throat area and the heel area;
a reinforcement element attached to only an inner surface of the braided upper along the connection area adjacent to an inner surface of the component, such that the reinforcement element covers the inner surface of braided upper without covering the inner surface of the component;
two rows of approximately parallel stitches passing through the reinforcement element and the braided upper to an outer surface of the braided upper opposite the inner surface to attach the reinforcement element to the inner surface of the braided upper; and
a zigzag stitch comprising a thread that passes through the inner surface of only the component at a first location and passes through both of the reinforcement element and the braided upper at a second location to attach the component to the braided upper at the connection area, wherein the second location is in a direction from the component that is laterally beyond the two rows of approximately parallel stitches attaching the reinforcement element to the inner surface of the braided upper;
wherein the thread of the zigzag stitch extends over at least one loop of the two rows of approximately parallel stitches attaching the reinforcement element to the inner surface of the braided upper; and
wherein the edges of the braided upper and the component are abutting along the connection area such that the braided upper and the component are arranged edge to edge.

10. The article of footwear according to claim 9 , wherein at least one loop of the two rows of approximately parallel stitches is disposed between the thread of the zigzag stitch and an outer surface of the reinforcement element.

11. The article of footwear according to claim 9 , wherein an outer edge of the component abuts the braided upper along each of a forward edge, a lateral instep edge, and a medial instep edge in the throat area of the braided upper.

12. The article of footwear according to claim 9 , further comprising a seam cover element disposed over a portion of the braided upper and a portion of the component along the connection area.

13. A method of making an upper for an article of footwear, the method comprising:
forming a braid body comprising at least one braided layer;
forming a component configured to attach to the braid body, wherein the component and the braid body together form at least a portion of the upper;
stitching a reinforcement element to only an inner surface of the braid body using a connecting stitch along a connection area where edges of the braid body and the component are abutting, wherein the reinforcement element is adjacent to an inner surface of the component and covers the inner surface of the braid body without covering the inner surface of the component;
the connecting stitch extending through the reinforcement element and the at least one braided layer to an outer surface of the braid body opposite the inner surface to attach the reinforcement element to the inner surface of the braid body;
stitching the component to the braid body at the connection area using a zigzag stitch comprising a thread that passes through the inner surface of only the component at a first location and passes through both of the reinforcement element and the braid body at a second location to attach the component to the braid body at the connection area, wherein the second location is in a direction from the component that is laterally beyond the connecting stitch joining the reinforcement element to the inner surface of the braid body,
wherein the thread of the zigzag stitch extends over at least one loop of the connecting stitch attaching the reinforcement element to the inner surface of the braid body; and
wherein edges of the braid body and the component are abutting along the connection area such that the braid body and the component are arranged edge to edge.

14. The method according to claim 13 , wherein the connecting stitch comprises two rows of approximately parallel stitches along the connection area.

15. The method according to claim 14 , wherein at least one loop of the two rows of approximately parallel stitches is disposed between the thread of the zigzag stitch and an outer surface of the reinforcement element.

16. The method according to claim 13 , wherein an outer edge of the component abuts the braid body along each of a forward edge, a lateral instep edge, and a medial instep edge in a throat area of the upper.

17. The method according to
