Abstract

A knitted component may include a knit element with a first surface and an opposite second surface. An inlaid yarn may extend through the knit element and between the first surface and the second surface. A secured area where the first surface and the second surface are secured together may be included, where the inlaid yarn is secured by loops forming the first surface and the second surface. A cushioning area may be included, where the cushioning area has a tubular construction such that the first surface and the second surface are separable, forming a cavity therebetween, and where the inlaid yarn extends through the cavity formed between the first surface and the second surface.

First claim

We claim:

1. A knitted component, comprising:
a knit element comprised of a plurality of yarns, the knit element comprising:
a first layer forming a first surface and a second layer forming an opposite second surface;
a secured area where at least a first knit loop of the knit element forms a portion of both the first layer and the second layer; and
an unsecured area where at least a second knit loop of the knit element forms a portion of the first layer and not the second layer, and where at least a third knit loop of the knit element forms a portion of the second layer and not the first layer;

an inlaid yarn extending through the knit element between the first layer and the second layer, wherein the inlaid yarn is a cushioning yarn texturized to loft;
where in the secured area, the inlaid yarn is secured by at least the first knit loop forming the first layer and the second layer; and
where the unsecured area comprises a tubular construction such that the first layer and the second layer are separable, forming a cavity there between, such that
the inlaid yarn extends through the cavity formed between the first layer and the second layer,
wherein the inlaid yarn is lofted to a first diameter in the unsecured area, wherein the inlaid yarn is compressed and has a second diameter in the secured area, and wherein the first diameter is larger than the second diameter.

2. The knitted component of claim 1 ,
wherein in the unsecured area, the second knit loop forming the portion of the first layer is located on a first side of the inlaid yarn, and
wherein in the unsecured area, the third knit loop forming the portion of the second layer is located on a second side of the inlaid yarn.

3. The knitted component of claim 1 , wherein the first diameter is at least 50% larger than the second diameter.

4. The knitted component of claim 1 , wherein the first diameter is at least twice as large as the second diameter.

5. The knitted component of claim 1 , wherein the unsecured area is configured to be placed in at least one of an ankle area, a midfoot area, a collar area, a throat area, and an underfoot area of an upper for an article of footwear.

6. The knitted component of claim 1 , wherein the first diameter is a maximum diameter.

7. A knitted component, comprising:
a knit element comprised of a plurality of yarns, the knit element having an unsecured area and a secured area, wherein the knit element has a first layer forming a first surface and a second layer forming an opposite second surface, the first layer and second layer being separable in the unsecured area and joined to each other in the secured area, wherein at least a first knit loop of the knit element forms a portion of both the first layer and the second layer in the secured area, wherein at least a second knit loop of the knit element forms a portion of the first layer and not the second layer in the unsecured area, and wherein at least a third knit loop of the knit element forms a portion of the second layer and not the first layer in the unsecured area; and
an inlaid yarn extending through the knit element and between the first layer and the second layer in the secured area and the unsecured area, wherein the inlaid yarn is a cushioning yarn texturized to loft,
wherein a first segment of the inlaid yarn extends through a first course of the knit element in the secured area and the unsecured area,
wherein the inlaid yarn is lofted to a first diameter in the unsecured area,
wherein the inlaid yarn is compressed and has a second diameter in the secured area, and
wherein the first diameter is larger than the second diameter.

8. The knitted component of claim 7 , wherein the secured area is adjacent to the unsecured area and has a double jersey knit structure.

9. The knitted component of claim 7 , wherein in the unsecured area, the inlaid yarn is located within a cavity formed between the first layer and the second layer of the knit element.

10. The knitted component of claim 7 , wherein in the unsecured area, the second knit loop is located on a first side of the inlaid yarn, and wherein the third knit loop is located on a second side of the inlaid yarn.

11. The knitted component of claim 7 , wherein the first diameter is at least 50% larger than the second diameter.

12. The knitted component of claim 7 , wherein the first diameter is at least twice as large as the second diameter.

13. The knitted component of claim 7 , wherein the first knit loop and the second knit loop are formed from a common continuous yarn.

14. The knitted component of claim 7 , wherein the unsecured area is configured to be placed in at least one of an ankle area, a midfoot area, a collar area, a throat area, and an underfoot area of an upper for an article of footwear.

15. The knitted component of claim 7 , wherein the first diameter is a maximum diameter, and wherein a second segment of the inlaid yarn extends through a second course in the secured area and the unsecured area of the knit element.

16. An upper for an article of footwear, the upper comprising:
a knitted component having a knit element comprised of a plurality of yarns, the knit element comprising:
a first layer forming a first surface and a second layer forming an opposite second surface;
a secured area where at least a first knit loop of the knit element forms a portion of both the first layer and the second layer; and
a first unsecured area where at least a second knit loop of the knit element forms a portion of the first layer and not the second layer, and where at least a third knit loop of the knit element forms a portion of the second layer and not the first layer;

an inlaid yarn texturized to loft, the inlaid yarn extending through the knit element between the first layer and the second layer;
wherein in the first unsecured area, the second knit loop is located on a first side of the inlaid yarn forming the first layer,
wherein in the first unsecured area, the third knit loop is located on a second side of the inlaid yarn forming the second layer, and
wherein the inlaid yarn is lofted to a first diameter in the first unsecured area, wherein the inlaid yarn is compressed and has a second diameter in the secured area, and wherein the first diameter is larger than the second diameter.

17. The upper of claim 16 , further comprising a fourth knit loop in the secured area, wherein the first knit loop is intermeshed with the fourth knit loop in the secured area.

18. The upper of claim 16 , wherein the first diameter is at least 50% larger than the second diameter.

19. The upper of claim 16 , wherein the first unsecured area is placed in an ankle area of the upper.

20. The upper of claim 16 , wherein the knitted component includes a second unsecured area that overlaps the first unsecured area such that the first unsecured area and the second unsecured area are at least partially coextensive.
