Abstract

An article of footwear includes an upper and a sole structure. The upper includes elongated members extending from a lower peripheral portion that mechanically connect the upper to a sole structure. The sole structure includes several recesses for engaging the elongated members. The upper and/or the elongated members can be printed using a three-dimensional printer.

First claim

What is claimed is:

1. An article of footwear, comprising:
an upper having a lower peripheral portion, wherein the upper includes an elongated member extending from the lower peripheral portion;
a sole structure having a top surface and an opposing bottom surface, wherein the top surface is disposed closer to the upper than is the bottom surface;
the sole structure including a recess disposed in the top surface and extending below the top surface toward the bottom surface;
the top surface of the sole structure further including an interior portion, and also including an outer peripheral portion disposed outwardly of the interior portion;
wherein the recess includes a first end portion disposed on the outer peripheral portion of the top surface, and a second end portion disposed on the interior portion of the top surface;
wherein the elongated member includes a first end portion and a second end portion;
wherein the first end portion of the elongated member engages the first end portion of the recess and the second end portion of the elongated member engages the second end portion of the recess; and
wherein the upper includes a cord element coupled with and extending along the lower peripheral portion of the upper, and wherein the elongated member is attached to the cord element.

2. The article of footwear according to claim 1 , wherein the elongated member includes an aperture and wherein the cord element is disposed through the aperture of the elongated member.

3. The article of footwear according to claim 1 , wherein:
the second end portion of the elongated member includes each of a first protrusion and a second protrusion;
wherein the second end portion of the recess includes each of a first notch and a second notch;
wherein the first protrusion engages the first notch; and
wherein the second protrusion engages the second notch.

4. The article of footwear according to claim 3 , wherein the second end portion of the elongated member includes at least a third protrusion, and wherein the second end portion of the recess includes at least a third notch.

5. The article of footwear according to claim 3 , wherein the second end portion of the elongated member comprises a top surface, and wherein the top surface of the second end portion is co-planar with the top surface of sole structure when the elongated member is engaged with the recess.

6. The article of footwear according to claim 1 , wherein the upper further comprises at least one mesh portion.

7. The article of footwear according to claim 6 , wherein the mesh portion is formed of a cured polymeric material suitable for dispensing from a three-dimensional printer when in an uncured state.

8. The article of footwear according to claim 1 , wherein the elongated member is formed of a cured polymeric material suitable for dispensing from a three-dimensional printer when in an uncured state.

9. An article of footwear, comprising:
an upper having a lower peripheral portion, wherein the upper includes an elongated member extending from the lower peripheral portion;
a sole structure having a top surface and an opposing bottom surface, wherein the top surface is disposed closer to the upper than is the bottom surface;
the sole structure including a recess disposed in the top surface;
the top surface of the sole structure further including an interior portion, and also including an outer peripheral portion disposed outwardly of the interior portion;
wherein the recess includes a first end portion associated with the outer peripheral portion of the top surface, and the recess includes a second end portion associated with the interior portion of the top surface;
wherein the elongated member includes a first end portion, and the elongated member includes a second end portion;
wherein the first end portion of the elongated member engages the first end portion of the recess, and the second end portion of the elongated member engages the second end portion of the recess;
wherein the upper includes a cord element coupled with and extending along the lower peripheral portion of the upper, and wherein the elongated member is attached to the cord element.

10. The article of footwear according to claim 9 , wherein the elongated member includes an aperture and the cord element is disposed through the aperture of the elongated member.

11. The article of footwear according to claim 9 , wherein the second end portion of the elongated member includes each of a first protrusion and a second protrusion;
wherein the second end portion of the recess includes each of a first notch and a second notch;
wherein the first protrusion engages the first notch; and
wherein the second protrusion engages the second notch.

12. The article of footwear according to claim 11 , wherein the second end portion of the elongated member includes at least a third protrusion, and the second end portion of the recess includes at least a third notch.

13. The article of footwear according to claim 11 , wherein the second end portion of the elongated member comprises a top surface, and the top surface of the second end portion is co-planar with the top surface of sole structure when the elongated member is engaged with the recess.

14. The article of footwear according to claim 9 , wherein the upper further comprises at least one mesh portion.

15. The article of footwear according to claim 14 , wherein the mesh portion is formed of a cured polymeric material suitable for dispensing from a three-dimensional printer when in an uncured state.

16. The article of footwear according to claim 9 , wherein the elongated member is formed of a cured polymeric material suitable for dispensing from a three-dimensional printer when in an uncured state.

17. An article of footwear, comprising:
an upper having a lower peripheral portion, wherein the upper includes an elongated member extending from the lower peripheral portion;
a sole structure having a top surface and an opposing bottom surface, wherein the top surface is disposed closer to the upper than is the bottom surface;
the sole structure including a recess disposed in the top surface;
the top surface of the sole structure further including an interior portion, and also including an outer peripheral portion disposed outwardly of the interior portion;
wherein:
the recess includes a first end portion associated with the outer peripheral portion of the top surface and a second end portion associated with the interior portion of the top surface;
the elongated member includes a first end portion and a second end portion;
the first end portion of the elongated member engages the first end portion of the recess and the second end portion of the elongated member engages the second end portion of the recess;
the second end portion of the elongated member includes each of a first protrusion and a second protrusion;
the second end portion of the recess includes each of a first notch and a second notch;
the first protrusion engages the first notch;
the second protrusion engages the second notch;
the second end portion of the elongated member comprises a top surface; and
the top surface of the second end portion is co-planar with the top surface of the sole structure when the elongated member is engaged with the recess.
