Guides for lacing systems
First Claim
1. A lace guide for routing a lace about an article comprising:
- a strip of woven material having a longitudinal length and a lateral width, the strip of woven material being folded along the longitudinal length to form a loop within which the lace is disposed and the strip of woven material having a center portion and two end portions along the lateral width, the two end portions being disposed on opposite sides of the center portion and being substantially parallel to one another and the two end portions being more flexible than the center portion so that
1) when the lace is tensioned, the two end portions flex or curve longitudinally outward more than the center portion to create a curved lace pathway that does not present sharp turns to the lace, and
2) when the lace is relaxed, the two end portions return to an un-flexed state to create a more linear lace pathway, wherein the center portion has sufficient strength to resist compression along the lateral width of the lace guide and thereby minimize the lace guide from bunching within the center portion when the lace is tensioned;
wherein the center portion and the two end portions are made from the same woven material and wherein the center portion has a greater material density than the two end portions such that the center portion is less flexible than the two end portions.

Abstract
Lacing systems are disclosed for use with footwear or other articles. The lacing system can include flexible webbing lace guides. A lace guide can include a first lace guide element and a second lace guide element. The lace can pass through the first and second lace guides consecutively on the first side of the article before crossing to the opposing side of the article. The first and second lace guide elements can be angled towards each other to reduce the occurrence of sharp turns in the lace path through the lace guide elements. The lace guide can have a central portion that is less flexible than the end portions so as to reduce the occurrence of sharp turns in the lace path through the lace guide when tension is applied to the lace.

6. A lace guide comprising a strip of woven material that is folded along a longitudinal length to form a loop, the strip of woven material having a center portion and opposing end portions that are more flexible than the center portion and that are configured to flex or curve longitudinally outward more than the center portion when the lace guide is in a tensioned state so as to create a curved lace pathway, the lace guides being further configured to return to an un-flexed position when the lace guide is in an un-tensioned state to create a more linear lace pathway, wherein the center portion has sufficient strength to resist compression along a lateral width of the lace guide and thereby minimize the lace guide from bunching within the center portion when the lace guide is in the tensioned state, and wherein the opposing end portions are substantially parallel to one another;
wherein the center portion has a greater material density than the two end portions such that the center portion is less flexible than the two end portions. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method of constructing a lace guide comprising:
-
providing a strip of woven material having a longitudinal length and a lateral width; and folding the strip of woven material along the longitudinal length to form a loop, the folded strip of woven material having a center portion and two end portions along the lateral width; wherein the two end portions are disposed on opposite sides of the center portion so that the two end portions are substantially parallel to one another and the two end portions are more flexible than the center portion so that; when the lace guide is in a tensioned state, the two end portions flex or curve longitudinally outward more than the center portion to create a curved lace pathway that does not present sharp turns to the lace, and when the lace guide is in an un-tensioned state, the two end portions return to an un-flexed state to create a more linear lace pathway; wherein the center portion has sufficient strength to resist compression along the lateral width of the lace guide and thereby minimize the lace guide from bunching within the center portion when the lace guide is in the tensioned state; wherein the center portion has a greater material density that the two end portions such that the center portion is less flexible than the two end portions. - View Dependent Claims (14, 15, 16, 17)
