Abstract

Claims (27)

1. A footwear assembly comprising:

a footwear upper including a toe box portion, a medial side, a lateral side, and a heel portion, the medial side and the lateral side each extending proximally from the toe box portion to the heel portion;

a lace cable with a first end anchored along a distal outside portion of the medial side and a second end anchored along a distal outside portion of the lateral side; and

a plurality of deformable lace guides distributed along the medial side and the lateral side, each deformable lace guide of the plurality of deformable lace guides including a straight tubular incoming extension to receive a length of lace cable and a straight tubular outgoing extension to expel the lace cable coupled to a tubular middle section that transitions between an first shape and a second shape, wherein each deformable lace guide forms the first shape in response to a first tension on the lace cable and the second shape in response to a second tension on the lace cable, and wherein each deformable lace guide contributes to the first tension in the first shape.

2. The footwear assembly of claim 1 , wherein the second tension is greater than the first tension and the change in tension is generated by a shortening of an overall length of the lace cable.

3. The footwear assembly of claim 2 , wherein deformation from the first shape to the second shape of each deformable lace guide of the plurality of deformable lace guides operates to flatten out a cable tension versus shortening length curve.

4. The footwear assembly of claim 1 , wherein each deformable lace guide is a tubular structure having a cylindrical cross-section.

5. The footwear assembly of claim 1 , wherein each deformable lace guide of the plurality of deformable lace guides is a U-shaped lace guide including the tubular middle section forming a curved portion of the U-shaped lace guide.

6. The footwear assembly of claim 5 , wherein the straight tubular incoming extension, the tubular middle section, and straight tubular outgoing extension all deform substantially uniformly in response to a change in tension from the first tension to the second tension.

7. The footwear assembly of claim 5 , wherein the straight tubular incoming extension and the straight tubular outgoing extension deform substantially uniformly in response to a change in tension from the first tension to the second tension.

8. The footwear assembly of claim 7 , wherein the tubular middle section exhibits negligible deformation between the first shape and the second shape in response to the change in tension.

9. The footwear assembly of claim 1 , wherein a first deformable lace guide of the plurality of deformable lace guides includes a first modulus of elasticity resulting in formation of the first shape in response to the first tension and the second shape in response to the second tension; and

wherein a second deformable lace guide of the plurality of deformable lace guides includes a second modulus of elasticity resulting in formation of a third shape in response to the first tension and a fourth shape in response to the second tension.

10. A footwear apparatus comprising:

a footwear upper including a lacing architecture routing a lace cable along a medial side or a lateral side of the footwear upper, the lacing architecture including a plurality of deformable lace guides, each deformable lace guide of the plurality of deformable lace guides includes a straight tubular incoming extension and a straight tubular outgoing extension coupled to a tubular middle section that transitions between an open state and a closed state based on tension the lace cable.

11. The footwear apparatus of claim 10 , further comprising a lacing engine including a drive mechanism to adjust an effective length of the lace cable between a first length and a second length, wherein the first length is longer than the second length; and

wherein the plurality of deformable lace guides transition to the open state in response to the lacing engine adjusting the lace cable to the first length, and the plurality of deformable lace guides transition to the closed state in response to the lacing engine adjusting the lace cable to the second length.

12. The footwear apparatus of claim 11 , wherein the plurality of deformable lace guides in the open state define a first route for the lace cable, and the plurality of deformable lace guides in the closed state define a second route for the lace cable, wherein the first length of the lace cable in combination with the plurality of deformable lace guides operate to induce an initial tension on the lace cable in the open state to define the first route.

13. The footwear apparatus of claim 12 , wherein the first route includes the lace cable traversing a first path between adjacent deformable lace guides that does not align with an incoming axis along the incoming extension or an outgoing axis along the outgoing extension.

14. The footwear apparatus of claim 12 , wherein the second route includes the lace cable traversing a second path between adjacent deformable lace guides that aligns with an incoming axis along the incoming extension or an outgoing axis along the outgoing extension.

15. The footwear apparatus of claim 11 , wherein the plurality of deformable lace guides apply a first tension on the lace cable when the lace cable is adjusted to the first length by the lacing engine.

16. The footwear apparatus of claim 15 , wherein the plurality of deformable lace guides apply a second tension on the lace cable when the lace cable is adjusted to the second length by the lacing engine, wherein the second tension is greater than the first tension.

17. The footwear apparatus of claim 10 , wherein the lacing architecture includes deformable lace guides distributed in an alternating pattern routing the lace in a wave pattern that cycles up and down along a medial or lateral side of the footwear upper, wherein the medial side and the lateral side of the footwear upper are separated by a central portion.

18. The footwear apparatus of claim 17 , wherein the alternating pattern routing the lace does not cross the central portion of the footwear upper, wherein the central portion includes a gap between the medial side and the lateral side of the footwear upper.

19. The footwear apparatus of claim 17 , wherein the alternating pattern of deformable lace guides routes the lace through at least two cycles of the wave pattern along the medial or lateral side of the footwear upper.

20. The footwear apparatus of claim 12 , wherein each deformable lace guide of the plurality of deformable lace guides includes a middle section joining the incoming extension and the outgoing extension; and

wherein the middle section includes a first modulus of elasticity, the incoming extension includes a second modulus of elasticity, and the outgoing extension includes a third modulus of elasticity.
