Abstract

A warp knit component that includes a first front weft inlaid yarn that extends through one or more loops in a first warp knit course, and after extending through the one or more loops, the first front weft inlaid yarn extends as a float positioned on a technical face or front side of the warp knit component. After extending as the float, the first front weft inlaid yarn extends through one or more loops in a second warp knit course that is offset in the material flow direction from the first warp knit course. Using floats facilitates the advancement of the first front weft inlaid yarn in the material flow direction.

First claim

What is claimed is:

1 . An integrally warp knit upper for an article of footwear, the integrally warp knit upper comprising:
a medial side and a lateral side; a plurality of warp knit courses that extend from the medial side to the lateral side; a first front weft inlaid yarn positioned on the lateral side of the upper, wherein: the first front weft inlaid yarn extends through at least one loop in a first warp knit course of the plurality of warp knit courses in a course-wise direction, after extending through the at least one loop in the first warp knit course, the first front weft inlaid yarn extends as a float positioned on an outer-facing surface of the integrally warp knit upper in a direction oblique to the course-wise direction, and after extending as the float, the first front weft inlaid yarn extends through at least one loop in a second warp knit course of the plurality of warp knit courses in the course-wise direction, the second warp knit course offset in a material flow direction from the first warp knit course, wherein the first front weft inlaid yarn forms a lace loop in a throat area of the upper; and a lace that extends through the lace loop.

2 . The integrally warp knit upper of claim 1 , further comprising a second front weft inlaid yarn positioned on the medial side of the upper, wherein:
the second front weft inlaid yarn extends through at least one loop in a third warp knit course of the plurality of warp knit courses, after extending through the at least one loop in the third warp knit course, the second front weft inlaid yarn extends as a float positioned on the outer-facing surface of the integrally warp knit upper, and after extending as the float, the second front weft inlaid yarn extends through at least one loop in a fourth warp knit course.

3 . The integrally warp knit upper of claim 2 , wherein the first front weft inlaid yarn is one or more of a different yarn type and a different denier than the second front weft inlaid yarn.

4 . The integrally warp knit upper of claim 2 , wherein the first front weft inlaid yarn forms a first geometric pattern on the lateral side of the upper, wherein the second front weft inlaid yarn forms a second geometric pattern on the medial side of the upper, and wherein the first geometric pattern comprises a different geometric pattern than the second geometric pattern.

5 . The integrally warp knit upper of claim 2 , wherein at least one of the first warp knit course and the second warp knit course is offset from at least one of the third warp knit course and the fourth warp knit course in a wale-wise direction.

6 . The integrally warp knit upper of claim 1 , further comprising a first back weft inlaid yarn that extends through every successive loop in the first warp knit course and a second back weft inlaid yarn that extends through every successive loop in the second warp knit course, the first back weft inlaid yarn and the second back weft inlaid yarn positioned on a technical back of the integrally warp knit upper.

7 . An integrally warp knit upper for an article of footwear, the integrally warp knit upper comprising:
a medial side and a lateral side; a plurality of warp knit courses that extend from the medial side to the lateral side, wherein at least some loops in adjacent courses of the plurality of warp knit courses interlock with each other; a first front weft inlaid yarn positioned on the lateral side of the upper; a second front weft inlaid yarn positioned on the medial side of the upper, wherein: the first front weft inlaid yarn extends through at least one loop in a first warp knit course of the plurality of warp knit courses, after extending through the at least one loop in the first warp knit course, the first front weft inlaid yarn extends as a float positioned on an outer-facing surface of the integrally warp knit upper, and after extending as the float, the first front weft inlaid yarn extends through at least one loop in a second warp knit course of the plurality of warp knit courses, the second warp knit course offset in a material flow direction from the first warp knit course, the second front weft inlaid yarn extends through at least one loop in a third warp knit course of the plurality of warp knit courses, after extending through the at least one loop in the third warp knit course, the second front weft inlaid yarn extends as a float positioned on the outer-facing surface of the integrally warp knit upper, after extending as the float, the second front weft inlaid yarn extends through at least one loop in a fourth warp knit course, at least one of the first warp knit course and the second warp knit course is offset from at least one of the third warp knit course and the fourth warp knit course in a wale-wise direction, wherein the first front weft inlaid yarn forms a lace loop in a throat area of the upper; and a lace that extends through the lace loop.

8 . An article of footwear comprising an integrally warp knit upper, the integrally warp knit upper comprising:
a medial side and a lateral side; a plurality of warp knit courses that extend from the medial side to the lateral side, wherein at least some loops in adjacent courses of the plurality of warp knit courses interlock with each other; a first front weft inlaid yarn positioned on the lateral side of the upper; wherein: the first front weft inlaid yarn extends through at least one loop in a first warp knit course of the plurality of warp knit courses, after extending through the at least one loop in the first warp knit course, the first front weft inlaid yarn extends as a float positioned on an outer-facing surface of the integrally warp knit upper, after extending as the float, the first front weft inlaid yarn extends through at least one loop in a second warp knit course of the plurality of warp knit courses, the second warp knit course offset in a material flow direction from the first warp knit course; the integrally warp knit upper further comprises a first back weft inlaid yarn that extends through every successive loop in the first warp knit course and a second back weft inlaid yarn that extends through every successive loop in the second warp knit course, the first back weft inlaid yarn and the second back weft inlaid yarn positioned on a technical back of the integrally warp knit upper; the article of footwear further comprises a sole structure secured to the integrally warp knit upper, wherein the first front weft inlaid yarn forms a lace loop in a throat area of the upper; and a lace that extends through the lace loop.
