Abstract

In one aspect, the present disclosure provides an article, which may be an upper for an article of footwear in some embodiments. The article may include a knitted component with a first zone and a second zone adjacent to the first zone. The knitted component may include a tab element extending from the first zone, where the tab element and the first zone include a common yarn. The first zone may include a first elasticity and the second zone may include a second elasticity, where the first elasticity is less than the second elasticity.

First claim

We claim:

1. An upper for an article of footwear, the upper comprising:
a knitted component with a first zone and a second zone, wherein the first zone and the second zone are located in a heel area of the upper; and
the knitted component including a tab element, the tab element having a first end extending from the first zone and a second end extending from the second zone, wherein the tab element and the first zone include at least one common yarn, and wherein the tab element and the second zone include at least one common yarn,
wherein the at least one common yarn includes a floating yarn having a tenacity of at least 5 g/D, and
wherein the tab element includes a plurality of courses of the knitted component, the floating yarn extending through at least one course of the plurality of courses in the tab element.

2. The upper of claim 1 , wherein the knitted component includes a third zone adjacent to the first zone, wherein the first zone includes an elasticity greater than an elasticity of the third zone.

3. The upper of claim 2 , wherein the third zone is configured to be located directly behind a heel of a user when the upper is incorporated into the article of footwear and when the article of footwear is in use.

4. The upper of claim 2 , wherein the third zone is located between the first zone and the second zone.

5. The upper of claim 1 , wherein the article is incorporated into the article of footwear, and when the article of footwear is resting with its sole structure on a horizontal surface.

6. The upper of claim 5 , wherein a first side of the tab element includes at least 10% fewer courses per unit length measured when the tab element is in a flattened state.

7. The upper of claim 1 , wherein the knitted component comprises a tongue with a top side and a bottom side, wherein the bottom side is formed from at least 30% more material than the top side such that the tongue has a tendency to curve in a direction corresponding to the top side.

8. The upper of claim 1 , wherein at least one of the first zone and the second zone extend from the tab element to a biteline of the upper.

9. An article, the article comprising:
a knitted component for forming at least a portion of an upper for an article of footwear, the knitted component including a first zone and a second zone adjacent to the first zone; and
the knitted component including a tab element extending from the first zone, wherein the tab element and the first zone include a common yarn,
wherein the first zone includes a first elasticity, wherein the second zone includes a second elasticity, and wherein the first elasticity is less than the second elasticity, and
wherein the first zone extends from the tab element to an area of the knitted component corresponding to a biteline of the article of footwear.

10. The article of claim 9 , wherein the common yarn is a floating yarn, and wherein the floating yarn has a tenacity of at least 5 g/D.

11. The article of claim 9 , wherein the first zone extends from the tab element to an edge of the article.

12. The article of claim 9 , wherein the common yarn includes a floating portion that extends substantially vertically when the article is incorporated into the article of footwear and when the article of footwear is resting with its sole structure on a horizontal surface.

13. The article of claim 9 , wherein the second zone is located directly behind a heel of a user when the upper is incorporated into the article of footwear and when the article of footwear is in use.

14. The article of claim 9 , wherein the tab element is flared such that a surface is oriented from 0° to 60° with respect to a plane parallel to a ground surface when the article is incorporated into the article of footwear, and when the article of footwear is resting with its sole structure on a horizontal surface.

15. The article of claim 14 , wherein a first side of the tab element includes at least 10% fewer courses per unit length than a second side when measured while the tab element is in a flattened state.

16. The article of claim 9 , wherein the knitted component comprises a tongue with a top side and a bottom side, wherein the bottom side is formed from at least 30% more material than the top side such that the tongue has a tendency to curve towards the top side.

17. An upper for an article of footwear, the upper comprising:
a knitted component with a first knitted zone and a third knitted zone, wherein the first knitted zone and the third knitted zone are located in a heel area of the upper;
the knitted component including a knitted tab element, the knitted tab element having a first end extending from the first knitted zone and a second end extending from the third knitted zone; and
the knitted component having a second knitted zone located between the first knitted zone and the third knitted zone, the second knitted zone having an elasticity that is higher than an elasticity of the first knitted zone and also an elasticity of the third knitted zone.

18. The upper of claim 17 , wherein at least one of the first knitted zone and the third knitted zone extends from the knitted tab element to a biteline of the article of footwear.

19. The upper of claim 17 , wherein at least one common yarn extends from the first knitted zone to the knitted tab element, and wherein the at least one common yarn includes a floating portion that extends vertically through the first knitted zone.
