Abstract

A lacing device includes a lace body, the lace body having a length, width, depth, and cross-sectional area spanning the width and the depth of the lace body, the cross-sectional area of the lace body shaped such that the lace body is prone to folding about a middle area of the width when the lace body is compressed.

First claim

What is claimed:

1. A lacing device comprising:
a lace body, the lace body having a length, a width defined between opposing side edges, a depth defined between opposing top and bottom surfaces, and a cross-sectional area spanning the width and the depth of the lace body, the cross-sectional area of the lace body shaped such that the lace body is prone to folding about a middle area of the width when the lace body is compressed,
wherein the cross-sectional area of the lace body has a narrow profile in the depth in the middle area as compared to edge areas outside the middle area of the width, the narrow profile defining a point of minimum thickness, the point of minimum thickness defined along a longitudinal centerline of the lace body and about which the lace body folds when compressed by a force applied between the opposing side edges.

2. The lacing device of claim 1 , wherein the cross-sectional area has a dogbone shape.

3. The lacing device of claim 1 , wherein the lace body includes a plurality of ridges.

4. The lacing device of claim 3 , wherein the plurality of ridges runs parallel to the length of the lace body.

5. The lacing device of claim 4 , wherein the lace body is composed of thermal plastic urethane (TPU).

6. The lacing device of claim 5 , wherein the lace body has a durometer of 65-75 shore A.

7. The lacing device of claim 5 , wherein the lace body includes a slip additive.

8. The lacing device of claim 1 , wherein the lace body is shaped such that a lever arm is created that stretches from an end point at an edge of the lace body to a center point of the lace body.

9. A lacing device comprising:
a lace body, the lace body having a length, a width defined between opposing side edges, a depth defined between opposing top and bottom surfaces, and a cross-sectional area spanning the width and the depth of the lace body, the cross-sectional area of the lace body shaped such that the lace body is prone to folding about a middle area of the width when the lace body is compressed, the lace body having a first configuration where the lace body is not under compressive force, and a second configuration where the lace body is under compressive force, the first configuration characterized by the lace body having a flat profile, and the second configuration characterized by the lace body being folded about the middle area of the width,
wherein the cross-sectional area of the lace body has a narrow profile in the depth in the middle area as compared to edge areas outside the middle area of the width, the narrow profile defining a point of minimum thickness, the point of minimum thickness defined along a longitudinal centerline of the lace body and about which the lace body folds when compressed by a force applied between the opposing side edges.

10. The lacing device of claim 9 , wherein the compressive force is a result of tying the lace body around itself.

11. The lacing device of claim 10 , wherein the lace body includes a plurality of ridges, and the plurality of ridges runs parallel to the length of the lace body.

12. The lacing device of claim 11 , wherein in the second configuration when the lace body is tied around itself, the plurality of ridges compresses and mechanically interacts with each other due to the compressive force.

13. The lacing device of claim 11 , wherein the lace body is composed of thermal plastic urethane (TPU), the lace body has a durometer of 65-75 shore A, and the lace body includes a slip additive.

14. A method of using a lacing device, the method comprising:
providing the lacing device, the lacing device having a lace body, the lace body having a length, a width defined between opposing side edges, a depth defined between opposing top and bottom surfaces, and a cross-sectional area spanning the width and the depth of the lace body, the cross-sectional area of the lace body shaped such that the lace body is prone to folding about a middle area of the width when the lace body is compressed, wherein the cross-sectional area of the lace body has a narrow profile in the depth in the middle area as compared to edge areas outside the middle area of the width, the narrow profile defining a point of minimum thickness, the point of minimum thickness defined along a longitudinal centerline of the lace body and about which the lace body folds when compressed by a force applied between the opposing side edges;
lacing a shoe with the lacing device; and
tying the lacing device, wherein the tying causes the lace body to fold about the middle area of the width.

15. The method of claim 14 , further comprising stretching the lacing device to remove the shoe without untying the lacing device.

16. The method of claim 14 , wherein the lace body includes a plurality of ridges, and the plurality of ridges runs parallel to the length of the lace body.

17. The method of claim 14 , wherein in the second configuration when the lace body is tied around itself, the plurality of ridges compresses and mechanically interacts with each other due to the compressive force.

18. The method of claim 14 , wherein the lace body is composed of thermal plastic urethane (TPU), the lace body has a durometer of 65-75 shore A, and the lace body includes a slip additive.

19. A lacing device comprising:
a lace body, wherein the lace body includes a plurality of ridges, and the plurality of ridges runs parallel to the length of the lace body,
wherein the lace body has a length, a width defined between opposing side edges, a depth defined between opposing top and bottom surfaces, and a cross-sectional area spanning the width and the depth of the lace body, the cross-sectional area of the lace body shaped such that the lace body is prone to folding about a middle area of the width when the lace body is compressed, and
wherein the cross-sectional area of the lace body has a narrow profile in the depth in the middle area as compared to edge areas outside the middle area of the width, the narrow profile defining a point of minimum thickness, the point of minimum thickness defined along a longitudinal centerline of the lace body and about which the lace body folds when compressed by a force applied between the opposing side edges.

20. The lacing device of claim 19 , wherein the lace body is composed of thermal plastic urethane (TPU).

21. The lacing device of claim 19 , wherein the cross-sectional area has a dogbone shape.

22. The lacing device of claim 19 , wherein the lace body has a durometer of 65-75 shore A.

23. The lacing device of claim 19 , wherein the lace body includes a slip additive.
