Closure systems for articles of footwear (“articles”) can include laces or other adjustment structures for adjusting the closure system and/or providing additional support or reinforcement to the articles. Some closure systems include more than one adjustment structure. For example, a closure system can have a lace that is interwoven between a medial side portion and a lateral side portion of the article. In addition to the lace, the closure system can include tensile strands. The tensile strands can extend from a sole structure of the article and be coupled to the lace. The tensile strands can be configured to provide additional adjustability to the closure system and/or support to the wearer's foot.
Described below are various embodiments of tensile strands that can, for example, improve the comfort of the article and/or improve the adjustability of the closure system.
In one representative embodiment, an article of footwear comprises a sole structure, an upper, and a tensile strand. The upper is coupled to the sole structure and has a medial portion, a lateral portion, an interior surface, and an exterior surface. The tensile strand has a first portion, a second portion, and a third portion disposed between the first and second portions. The first and second portions are disposed adjacent the interior surface of the upper and have a first cross-sectional profile that is flat. The third portion extends from the exterior surface of the upper and has a second cross-sectional profile that is rounded.

In some embodiments, the article of footwear further comprises a lace member that extends between the medial and lateral portions of the upper and engages the tensile strands.
In some embodiments, the plurality of tensile strands includes a first tensile strand disposed on the medial portion of the upper and a second tensile strand disposed on the lateral portion of the upper.
In some embodiments, the plurality of tensile strands includes a first plurality of tensile strands disposed on the medial portion of the upper and a second plurality of tensile strands disposed on the lateral portion of the upper.
In another representative embodiment, an article of footwear comprises a sole structure, an upper, and a tensile strand. The upper is coupled to the sole structure and has a medial portion, a lateral portion, an interior surface, and an exterior surface. The tensile strand has a plurality of first portions, a plurality second portions. The first portions are disposed adjacent the interior surface of the upper and have flat cross-sectional profiles. The second portions are disposed between adjacent first portions, extend from the exterior surface of the upper, and have rounded cross-sectional profiles.
In some embodiments, the upper further comprises a lower edge and an upper edge, wherein the first portions of the tensile strand extend from the lower edge of the upper toward the upper edge of the upper.
In some embodiments, at least some of the first portions are coupled to the sole structure or the upper.
In some embodiments, the upper includes a slotted eyelet having a major axis and a minor axis, and a width of the slotted eyelet along the major axis is larger than thickness of the slotted eyelet along the minor axis.
In the certain embodiments, the article 100 can take the form of an athletic shoe, such as a tennis shoe, a running shoe, or a basketball shoe. It should be noted, however, that the article can take various other forms, including hiking boots, skateboarding shoes, sandals, and other types of footwear.
In some embodiments, the sole structure 102 and the upper 104 can be formed as a single, integral structure. In other embodiments, the upper 104 can be coupled to the sole structure 102, as shown, for example, in the illustrated embodiment.
Generally, the upper 104 can be any type of upper. For example, in embodiments where the article 100 is a tennis shoe or a running shoe, the upper 104 can be a low-top upper. In embodiments where the article 100 is a basketball shoe, the upper 104 can be a high-top upper that is shaped to provide high support on a wearer's ankle.
The upper 104 can have a lateral side portion 106, a medial side portion 108 (
The article 100 can further comprise a lace (or primary lace) 120 and one or more tensile strands (or secondary laces) 122. The lace 120 and the tensile strands 122 together with eyelets 114 and openings 116 of the upper 104 can form a closure system of the article 100. The closure system can be opened or loosened such that the wearer can insert their foot into the article 100. The closure system can also be closed or tightened to secure the article 100 to the wearer's foot.
Referring now to
The lace 120 can articulate relative to the eyelets 114 and/or the openings 116 to help accommodate various tensions of the lace 120 and/or the tensile strands 122. The configuration of the eyelets 114 and/or openings 116 can thereby provide improved adjustability, which can help accommodate various shapes and/or sizes of feet. This can be accomplished in several ways. For example, referring to
For example, referring to the uppermost eyelet 114 shown in
As shown in
In certain embodiments, a ratio of the width WS of the slotted eyelet 114 to the width WL of the lace 120 can be 1.1-4.0 or, in some embodiments, 1.5-3.5.
In some embodiments, a ratio of the thickness TS of the slotted eyelet 114 to the thickness TL of the lace 120 can be 0.9-1.1 or, in some embodiments, 0.95-1.05.
The openings 116 can comprise various shapes such as circular, rectangular, ovular, triangular, star-shaped, etc. The openings 116 can be aligned with the major axis A1 of the slotted eyelet 114. For example, a center-point or midpoint of the opening 116 can be aligned with the major axis A1 of the slotted eyelet 114.
The openings 116 can be spaced from the slotted eyelet by a distance D1. In particular embodiments, the distance D1 can be 0.1-3.0 inches or 0.25-2.0 inches. In some embodiments, D1 can be greater than or equal to a length of the exposed portion of the tensile strand 122 when the tensile strand is in a relaxed condition.
In some embodiments, the slotted eyelets 114 can be used with articles that do not have tensile strands 122. For example, the slotted eyelets 114 can be used with an article that has loop or secondary eyelets that are formed in or coupled to the upper 104.
In lieu of or in addition to the slotted eyelets 114, a first portion of the upper 104 that is adjacent to the eyelets 114 can be formed from relatively flexible or elastic material, and a second portion of the upper 104 that is adjacent to the openings 116 can be formed from relatively stiff or inelastic material. As such, the eyelets 114 can translate relative to their respective openings 116 as the flexible material of the upper stretches when the lace 120 is tightened. In such embodiments the distance D1 can increase by 10-25% or 0.1-0.5 inches from when the lace 120 is slackened to when the lace is tightened.
Referring to
The tensile strands 122 can, for example, be formed of a relatively less stretchable material that the upper 104. As such, the tensile strands 122 can provide additional support to the wearer's feet. This additional support can, for example, be advantageous during activities (e.g., tennis, basketball, etc.) with frequent acceleration, deceleration, and/or direction changes.
In some embodiments, the tensile strands 122 can be V-shaped. The “legs” of the “V” can be coupled to the sole structure 102, and the “point” of the “V” can extend through the opening 116 of the upper 104. In certain embodiments, the legs of adjacent tensile strands can overlap.
In some embodiments, a separate tensile strand 122 can extend through each opening 116 of the upper 104 with an exposed portion forming the loops 124. In other words, an upper having sixteen openings (i.e., eight openings on the lateral side and eight openings on the medial side) can have 16 tensile strands, each extending from the sole structure 102 and through a respective opening 116 of the upper 104.
In another embodiment, loops or eyelets (e.g., similar to loops 124) can be coupled to the tensile strands (e.g., at ends of the tensile strands). In other embodiments, the loops or eyelets can be connected to the upper.
In other embodiments, one or more of the tensile strands 122 can extend through a plurality of openings 116 in the upper 104. For example, a first tensile strand can extend through each of the openings 116 on the lateral side portion 106 of the upper 104, and a second tensile strand can extend through each of the openings 116 on the medial side portion 108 of the upper 104. In such embodiments, each tensile strand 122 can extend from the sole structure 102, through a first opening in the upper 104, back to the sole structure, through a second opening in the upper, back to the sole structure, and so on. Stated another way, one tensile strand can zigzag between the sole structure 102 and the openings 116 that are disposed on the lateral side portion 106 of the upper 104, and another tensile strand can zigzag between the sole structure 102 and the openings 116 that are disposed on the medial side portion 108 of the upper 104. The tensile strands 122 can be secured to the sole structure 102 and/or the upper 104 at each end (i.e., toward the toe and heel portions) and/or at various intermediate locations.
As mentioned above, a portion of the tensile strands 122 can form the loops 124 that extend from the openings 116 and through which the lace 120 extends.
In particular embodiments, the tensile strands 122 can also have a plurality of portions or sections. One or more of those portions can have a different cross-sectional profile or shape than one or more other portions. For example, referring to
The flat portions 126 can be coupled to the sole structure 102 and can be sized and/or configured to extend along the interior (i.e., non-exposed) surface of the upper 104. In this manner, the flat portions 126 are disposed between the wearer's foot and the interior surface of the upper 104 when the wearer's foot is inserted into the article 100. The profile of the flat portions 126 of the tensile strands 122 can be relatively wide compared to the thickness. For example, the flat portions 126 of the tensile strands 122 can be ⅜-¾ inches wide and 1/32- 1/16 inches thick. This flat profile can, for example, distribute load or pressure from the tensile strand 122 on the wearer's foot and upper over a wide area (and without adding undesirable bumps or bulges to the upper. Configuring the tensile strands 122 in this manner can, for example, improve the wearer's comfort and/or increase support to the wearer's foot.
The tensile strands 122 can be sized and/or configured such that the round portions 128 extend through the openings 116 and extend outwardly from an exterior surface of the upper 104. The circular or annular cross-sectional profile can, for example, allow the round portions 128 of the tensile strands 122 to more easily fit through and/or move relative to the openings 116 than a cross-sectional profile with edges or corners (e.g., rectangular, triangular, etc.). The round portions 128 of the tensile strands 122, which can include the loops 124, can also facilitate movement of the lace member 120 through the loops 124, thus improving the adjustability of the closure system of the article 100.
Accordingly, the tensile strands 122 that have a plurality of a plurality of portions with different cross-sectional profiles (e.g., flat-round-flat) can, for example, improve the comfort of the article and/or improve the functionality of the closure system.
A tensile strand having a plurality of cross-sectional profiles can be formed in various ways. For example, in some embodiments, the flat portions 126 and the round portions 128 can be formed as separate pieces that are coupled together with adhesive, fasteners, stitching, and/or other means for coupling. In other embodiments, the flat and round portions 126, 128 can be integrally formed as a single, continuous piece of material.
Additional information regarding tensile strands can be found, for example, in U.S. Pat. Nos. 9,113,674 and 9,681,706, which are incorporated by reference herein.
The technologies from any example can be combined with the technologies described in any one or more of the other examples. For example, one or more of the technologies described with respect to an article having the slotted eyelets 114 can be combined with one or more of the technologies described with respect to an article having the flat-round-flat tensile strands 122, or vice versa. As another example, the various technologies of any example can be separated from one or more of the other technologies of the example. For example, an article may have the slotted eyelets 114 and not the flat-round-flat tensile strands 122, or vice versa.
It should be noted that, although the exemplary embodiments are directed to articles of footwear, the disclosed technology can be adapted to various other items with laced closures systems (e.g., gloves, etc.).
In view of the many possible embodiments to which the principles of the disclosure may be applied, it should be recognized that the illustrated embodiments are only preferred examples and should not be taken as limiting the scope of the claims. Rather, the scope of the claimed subject matter is defined by the following claims and their equivalents.
This application claims the benefit of U.S. Provisional Application No. 62/628,754, filed Feb. 9, 2018, which is incorporated by reference herein.
