Abstract

A tensioning system for an article of footwear is disclosed. The tensioning system includes a reel member configured to rotate about a central axis. The reel member includes a shaft and at least one flange disposed along the shaft. The flange includes an aperture extending through the flange. The aperture is configured to receive a lace. The reel member can tighten the tensioning system by winding the lace around portions of the shaft disposed on both sides of the at least one flange. In some cases, the aperture can be chamfered to assist with sliding the lace through the aperture.

First claim

What is claimed is:

1. A tensioning system for an article of footwear, comprising:
a reel member configured to rotate about a central axis; the reel member comprising:
a shaft including a longitudinal axis running from a first end to a second end; and
at least one flange, including a first face opposite a second face; disposed along the shaft with the shaft running through a center of the at least one flange from the first face to the second face;
wherein the at least one flange includes an aperture extending parallel to the longitudinal axis through from the first face to the second face of the flange; and
a lace including a first end; a second end, and a middle portion, wherein a first segment of the middle portion extends through the aperture;

and
wherein rotating the reel member winds a second segment of the middle portion of the lace onto the shaft adjacent the first face and a third segment of the middle portion of the lace onto the shaft adjacent the second face inducing tension on the lace.

2. The tensioning system according to claim 1 , wherein the reel member rotates about the central axis in a first rotational direction to wind the lace to tighten the tensioning system.

3. The tensioning system according to claim 2 , wherein the reel member rotates about the central axis in a second rotational direction that is opposite the first rotational direction to unwind the lace to loosen the tensioning system.

4. The tensioning system according to claim 3 , wherein rotation in at least one of the first rotational direction and the second rotational direction is performed using a motor associated with the tensioning system.

5. The tensioning system according to claim 3 , wherein rotation in the second rotational direction is performed by applying tension to the lace while the tensioning system is in a loosened condition.

6. The tensioning system according to claim 1 , wherein the flange extends radially outward from the shaft; and
wherein the aperture is spaced apart from the shaft.

7. The tensioning system according to claim 1 , wherein the aperture is located adjacent to a perimeter edge of the flange.

8. A tensioning system for an article of footwear, comprising:
a motor;
a reel member in communication with the motor; and
a lace;
the reel member comprising a shaft including a longitudinal axis running from a first end to a second end and at least three flanges disposed along the shaft;
wherein a center flange of the at least three flanges includes an aperture extending through the center flange from a first face to a second face of the center flange, the aperture aligned with the longitudinal axis;
wherein a portion of the lace extends through the aperture in the center flange to interconnect the lace with the reel member; and
wherein the lace is configured to be wound around portions of the shaft disposed on opposite sides of the center flange when the tensioning system is in a tightened condition.

9. The tensioning system according to claim 8 , wherein equal portions of lace are disposed on opposite sides of the flange when the tensioning system is in the tightened condition.

10. The tensioning system according to claim 8 , wherein equal portions of lace are unwound from opposite sides of the flange when the tensioning system is placed in a loosened condition from the tightened condition.

11. The tensioning system according to claim 8 , wherein the aperture is chamfered around a circumference of the aperture.

12. The tensioning system according to claim 8 , wherein the lace is configured to slide through the aperture to adjust tension in different portions of the tensioning system.

13. The tensioning system according to claim 12 , wherein the lace is slid through the aperture to adjust an amount of a first portion of the lace that is associated with a midfoot region of an article of footwear and to adjust an amount of a second portion of the lace that is associated with a forefoot region of the article of footwear.

14. The tensioning system according to claim 8 , wherein the at least three flanges include a first end flange, the center flange, and a second end flange; and
wherein the center flange is located on the shaft between the first end flange and the second end flange.

15. The tensioning system according to claim 14 , wherein a first portion of lace is wound on a first shaft section disposed between the first end flange and the center flange when the tensioning system is in the tightened condition; and
wherein a second portion of lace is wound on a second shaft section disposed between the second end flange and the center flange when the tensioning system is in the tightened condition.
