The present embodiments relate generally to articles of footwear, and in particular to articles of footwear for sports.
Articles of footwear generally include two primary elements: an upper and a sole structure. The upper may be formed from a variety of materials that are stitched or adhesively bonded together to form a void within the footwear for comfortably and securely receiving a foot. The sole structure is secured to a lower portion of the upper and is generally positioned between the foot and the ground. In many articles of footwear, including athletic footwear styles, the sole structure often incorporates an insole, a midsole, and an outsole.
In one aspect, the present disclosure is directed to an article of footwear, the article of footwear comprising an upper, wherein the upper includes an outermost surface, and the upper further includes an inner liner and an outer liner. The article of footwear also includes a fastening system, where the fastening system has a fastener, at least two tensile elements, and a receptacle. At least a portion of the at least two tensile elements are disposed between the inner liner and the outer liner, and at least two tensile elements are joined to the receptacle. In addition, the fastener is disposed proximate the outermost surface, and the fastener engages with the receptacle.
In another aspect, the present disclosure is directed to an article of footwear, the article of footwear comprising a base axis, a first diagonal axis, and a second diagonal axis, where the base axis, the first diagonal axis, and the second diagonal axis are nonparallel, and where the base axis extends from one side of the article of footwear to an opposing side of the article of footwear.

Other systems, methods, features and advantages of the embodiments will be, or will become, apparent to one of ordinary skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description and this summary, be within the scope of the embodiments, and be protected by the following claims.
The embodiments can be better understood with reference to the following drawings and description. The components in the figures are not necessarily to scale; emphasis is instead being placed upon illustrating the principles of the embodiments. Moreover, in the figures, like reference numerals designate corresponding parts throughout the different views.
For purposes of clarity, the following detailed description discusses the features of article of footwear 100, also referred to simply as article 100. However, it will be understood that other embodiments may incorporate a corresponding article of footwear (e.g., a right article of footwear when article 100 is a left article of footwear) that may share some, and possibly all, of the features of article 100 described herein and shown in the figures.
The embodiments may be characterized by various directional adjectives and reference portions. These directions and reference portions may facilitate in describing the portions of an article of footwear. Moreover, these directions and reference portions may also be used in describing sub-components of an article of footwear (e.g., directions and/or portions of a midsole structure, an outer sole structure, a fastening system, an upper or any other components).
For consistency and convenience, directional adjectives are employed throughout this detailed description corresponding to the illustrated embodiments. The term “longitudinal” as used throughout this detailed description and in the claims refers to a direction or axis extending a length of a component (e.g., an upper or sole component). In some embodiments, a longitudinal direction may extend from a forefoot portion to a heel portion of the component. Also, the term “lateral” as used throughout this detailed description and in the claims refers to a direction or axis extending along a width of a component. For example, a lateral direction may extend between a medial side and a lateral side of a component. Furthermore, the term “vertical” as used throughout this detailed description and in the claims refers to a direction or axis generally perpendicular to a lateral and longitudinal direction. For example, in embodiments where an article is planted flat on a ground surface, a vertical direction may extend from the ground surface upward. Additionally, the term “inner” refers to a portion of an article disposed closer to an interior of an article, or closer to a foot when the article is worn. Likewise, the term “outer” refers to a portion of an article disposed further from the interior of the article or from the foot. Thus, for example, the inner surface of a component is disposed closer to an interior of the article than the outer surface of the component. Furthermore, the term “beneath” refers to a relative position closer toward the ground, a sole structure, and/or an interior cavity of the article of footwear. The term “above” refers to a relative position that is opposite to beneath. This detailed description makes use of these directional adjectives in describing an article and various components of the article, including an upper, a midsole structure and/or an outer sole structure.
Article 100 may be characterized by a number of different regions or portions. For example, article 100 could include a forefoot portion, a midfoot portion, a heel portion, a vamp portion, and an instep portion. Moreover, components of article 100 could likewise comprise corresponding portions. Referring to
In addition, article 100 may include a lateral side 16 and a medial side 18. In particular, lateral side 16 and medial side 18 may be opposing sides of article 100. Furthermore, both lateral side 16 and medial side 18 may extend through forefoot portion 10, midfoot portion 12, heel portion 14, vamp portion 11, and instep portion 13.
Furthermore, in some embodiments, sole structure 130 may be configured to provide traction for article 100. Thus, in different embodiments, traction elements may be included in sole structure 130. In addition to providing traction, sole structure 130 may attenuate ground reaction forces when compressed between the foot and the ground during walking, running, pushing, or other ambulatory activities. The configuration of sole structure 130 may vary significantly in different embodiments to include a variety of conventional or nonconventional structures. In some embodiments, the configuration of sole structure 130 can be configured according to one or more types of surfaces on which sole structure 130 may be used. Examples of surfaces include, but are not limited to, natural turf, synthetic turf, dirt, hardwood flooring, skims, wood, plates, footboards, boat ramps, as well as other surfaces.
The various portions of sole structure 130 may be formed from a variety of materials. For example, sole structure 130 may include a compressible polymer foam element (e.g., a polyurethane or ethylvinylacetate foam) that attenuates ground reaction forces (i.e., provides cushioning) when compressed between the foot and the ground during walking, running, or other ambulatory activities. In further configurations, sole structure 130 may incorporate fluid-filled chambers, plates, moderators, or other elements that further attenuate forces, enhance stability, or influence the motions of the foot. Furthermore, other portions of sole structure 130, such as an outsole 128, can be formed from a wear-resistant rubber material that is textured to impart traction. It should be understood that the embodiments herein depict a configuration for sole structure 130 as an example of a sole structure that may be used in connection with upper 102, and a variety of other conventional or nonconventional configurations for sole structure 130 may also be utilized. Accordingly, the structure and features of sole structure 130 or any sole structure utilized with upper 102 may vary considerably.
Sole structure 130 is secured to upper 102 and extends between a foot and the ground when article 100 is worn. In different embodiments, sole structure 130 may include different components. For example, sole structure 130 may include outsole 128. Sole structure 130 may further include a midsole and/or an insole. In some embodiments, one or more of these components may be optional. In addition, sole structure 130 may include components or portions that extend toward and/or attach to a portion of upper 102. Such components may provide additional support and compressive strength to article 100. For example, a reinforcing member 104 may extend along or be disposed adjacent to a portion of lateral side 16 or medial side 18 of upper 102. In some embodiments, reinforcing member 104 may extend along or be disposed adjacent to various portions of upper 102. In
In different embodiments, upper 102 may be joined to sole structure 130 and define an interior cavity 106 designed to receiver a wearer's foot. In some embodiments, upper 102 includes a mouth 114 that provides access for the foot into interior cavity 106 of upper 102. Mouth 114 may be disposed along or near the ankle portion in some embodiments. Furthermore, in some embodiments, a lace 134 can extend through various apertures or other securing elements and permit the wearer to modify dimensions of upper 102 to accommodate the proportions of the foot. More particularly, lace 134 may permit the wearer to tighten portions of upper 102 around the foot, and lace 134 can permit the wearer to loosen upper 102 to facilitate entry and removal of the foot from mouth 114. In alternative embodiments, upper 102 may include other lace-receiving elements, such as loops, eyelets, and D-rings. In addition, upper 102 includes a tongue 122 that extends between interior cavity 106 and lace 134.
Upper 102 may generally incorporate various provisions associated with uppers. Upper 102 may also be characterized by one or more layers disposed adjacent to one another. In some embodiments, each layer of upper 102 can be configured to provide various degrees of cushioning, tension, ventilation, shock absorption, energy return, support, as well as possibly other provisions.
For example, in some embodiments, upper 102 may include a base layer, an inner liner or layer, an outer liner or layer, and/or a protective layer. Referring to
In addition, upper 102 may include an inner liner (see inner liner 800 in
In some embodiments, upper 102 may also include outer liner 112, which may comprise at least a portion of the outer or exposed surface of upper 102. Thus, outer liner 112 can be disposed further away from interior cavity 106 than base layer 116 and/or the inner liner. In one embodiment, outer liner 112 may be disposed directly over the surface of the inner liner. In embodiments where upper 102 does not include an inner liner, outer liner 112 may be disposed directly adjacent to or over base layer 116. Furthermore, in some embodiments, outer liner 112 may also be disposed along at least some of tongue 122. In other embodiments, outer liner 112 can extend over only some portions of base layer 116. In some embodiments, outer liner 112 can be disposed such that it covers substantially all of the exterior surface of the inner liner. In addition, in one embodiment, outer liner 112 may at least partially comprise the outermost layer (i.e., the most exterior layer, and/or the layer disposed furthest from interior cavity 106) of upper 102. In some embodiments, outer liner 112 may include a mesh material, or otherwise include perforations that expose areas beneath outer liner 112 (e.g., portions of the fastening system, tongue 122, the inner liner, base layer 116, and/or lacing system). It should be understood that in some embodiments, article 100 may not include outer liner 112.
Furthermore, in some embodiments, upper 102 includes a protective layer 118. Protective layer 118 may comprise at least a portion of the outer or exposed surface of upper 102. In some embodiments, protective layer 118 may be disposed over or joined to portions of outer liner 112. For example, in
In different embodiments, each of the materials that may comprise the layer(s) of upper 102 can include various properties. The various portions of upper 102 may be formed from one or more of a plurality of material elements (e.g., textiles, polymer sheets, foam layers, leather, synthetic leather, knitted fabrics, etc.) that are stitched together or otherwise laid or disposed adjacent to one another to form upper 102. Other materials that could be used in various embodiments include, but are not limited to: expanded rubber, foam rubber, various kinds of foams, polyurethane, nylon, Gore-Tex, leather, plastic, textiles, as well as possibly other materials. Other parts of upper 102 may be made from any of a plurality of materials or combination of materials, such as leather, leather-like materials, polymer materials, plastic materials, and textile fabrics and materials.
In addition, each of the layers comprising upper 102 may be formed from any generally two-dimensional material. As utilized with respect to the present invention, the term “two-dimensional material” or variants thereof is intended to encompass generally flat materials exhibiting a length and a width that are substantially greater than a thickness. Accordingly, suitable materials for upper layers (e.g., base layer 116, the inner liner, outer liner 112, and/or protective layer 118) include various textiles, polymer sheets, or combinations of textiles and polymer sheets, for example. Textiles are generally manufactured from fibers, filaments, or yarns that are, for example, either (a) produced directly from webs of fibers by bonding, fusing, or interlocking to construct non-woven fabrics and felts or (b) formed through a mechanical manipulation of yarn to produce a woven or knitted fabric. The textiles may incorporate fibers that are arranged to impart one-directional stretch or multidirectional stretch, and the textiles may include coatings that form a breathable and water-resistant barrier, for example. The polymer sheets may be extruded, rolled, or otherwise formed from a polymer material to exhibit a generally flat aspect. Two-dimensional materials may also encompass laminated or otherwise layered materials that include two or more layers of textiles, polymer sheets, or combinations of textiles and polymer sheets. In addition to textiles and polymer sheets, other two-dimensional materials may be utilized for upper 102. Although two-dimensional materials may have smooth or generally untextured surfaces, some two-dimensional materials will exhibit textures or other surface characteristics, such as dimpling, protrusions, ribs, or various patterns, for example. Despite the presence of surface characteristics, two-dimensional materials remain generally flat and exhibit a length and a width that are substantially greater than a thickness. In some configurations, mesh materials or perforated materials may be utilized for upper. For example, the inner liner, outer liner 112, and/or protective layer 118 may comprise a mesh material, which may impart greater breathability or air permeability to article 100.
Referring to
In different embodiments, fastening system 120 could incorporate various fastening provisions including laces, tensile elements, straps, fasteners, zippers or other kinds of components that may help secure upper 102 around a foot. In some embodiments, fastening system 120 may include one or more fasteners 108, as noted above. In one embodiment, fasteners 108 may comprise an elongated strap-like component that may be wrapped around a portion of upper 102.
In the embodiment of
In addition, in one embodiment, fasteners 108 may include provisions for gripping or holding the fastener. As shown in
For purposes of reference, first fastener 124 may be divided into a fixed portion and a free portion. As shown in
In some embodiments, fixed portion 140 may be joined to a part of upper 102 by one or more anchor portions. In
Furthermore, it should be understood that fixed portion 140 can vary in size and shape. In some embodiments, fixed portion 140 may comprise a larger or smaller proportion of first fastener 124 than depicted in
As noted above, first fastener 124 also includes a free portion 148. For purposes of this disclosure, “free” refers to the ability of an element or material to be moved or adjusted. Thus, free portion 148 of first fastener 124 may be adjusted or otherwise moved to the extent permitted by the disposition of fixed portion 140. It can be seen that due to the orientation of fixed portion 140, free portion 148 is also generally oriented along a diagonal direction extending from forefoot portion 10 on medial side 18 toward midfoot portion 12 on lateral side 16, similar to fixed portion 140 (i.e., first diagonal axis 172). However, it should be understood that free portion 148 may also be readily bent, folded, curled, adjusted, or otherwise moved to include other orientations or positions. Free portion 148 and the operation of first fastener 124 will be discussed in further detail below with respect to
As shown in

In different embodiments, first fastener 124 may extend from anchor portion 168, extend over vamp portion 11, and be passed through first receptacle 144. In some embodiments, first fastener 124 may loop through and/or fold over first receptacle 144, forming a first looping section 198 (see
For example, in
For purposes of reference, second receptacle 146 may include different regions. For example, second receptacle 146 may comprise an upper region 180 and a lower region 182. In some embodiments, first fastener 124 may extend through an aperture 152 disposed within upper region 180 of second receptacle 146. Upper region 180 may comprise various geometries. In one embodiment, upper region 180 of second receptacle 146 is a substantially oblong rectangular frame, and can be joined directly to lower region 182. In some embodiments, lower region 182 of second receptacle 146 can be further joined or linked to another element of fastening system 120. As will be described in further detail below with respect to
Thus, in one embodiment, first fastener 124 may loop through and/or fold over upper region 180, forming a second looping section 199. In some embodiments, first fastener 124 may then extend back toward the direction of first receptacle 144 on lateral side 16. The operation of first fastener 124 with second receptacle 146 will be discussed further below with respect to
Fastening system 120 may also include additional components. As noted above, in some embodiments, fastening system 120 can include one or more tensile elements 132. Areas of one or both of lateral side 16 and medial side 18 can incorporate tensile elements 132. Referring to
In one embodiment, portions of one or more tensile elements 132 may be generally aligned with a second diagonal axis 174. Second diagonal axis 174 may be nonparallel to first diagonal axis 172 in some embodiments. It can also be seen that second diagonal axis 174 is nonparallel to both lateral axis 20 and longitudinal axis 22 in the embodiment of
In other words, tensile elements 132 may have various orientations that differ from those depicted. The angle of tensile elements 132 may be arranged in an orientation between zero and 90 degrees from the direction along longitudinal axis when viewing article 100 from the top-down (as in
It should be understood that other embodiments may include less than six tensile elements 132 or more than six tensile elements 132. Thus, in different embodiments, the various tensile elements 132 may be absent, or additional tensile elements 132 may be present to provide further structural components in article 100. Thus, upper 102 can include regions where tensile elements 132 are absent (e.g., along heel portion 14), which may enhance the stretch of article 100 in that area.
Referring also to
Furthermore, tensile elements 132 may engage with elements or materials disposed in other areas of upper 102. Thus, upper 102 may include provisions for routing tensile elements 132 outside or beyond outer liner 112, or for providing access to other areas of article 100. For example, in the embodiment of
Tensile elements 132 may be formed from any generally one-dimensional material. As utilized with respect to the present invention, the term “one-dimensional material” or variants thereof is intended to encompass generally elongate materials exhibiting a length that is substantially greater than a width and a thickness. Accordingly, suitable materials for tensile elements 132 include various filaments, fibers, yarns, threads, cables, or ropes that are formed from rayon, nylon, polyester, polyacrylic, silk, cotton, carbon, glass, aramids (e.g., para-aramid fibers and meta-aramid fibers), ultra high molecular weight polyethylene, liquid crystal polymer, copper, aluminum, and steel. Whereas filaments have an indefinite length and may be utilized individually as tensile elements 132, fibers have a relatively short length and generally go through spinning or twisting processes to produce a strand of suitable length. An individual filament utilized in tensile elements 132 may be formed form a single material (i.e., a monocomponent filament) or from multiple materials (i.e., a bicomponent filament). Similarly, different filaments may be formed from different materials. As an example, yarns utilized as tensile elements 132 may include filaments that are each formed from a common material, may include filaments that are each formed from two or more different materials, or may include filaments that are each formed from two or more different materials. Similar concepts also apply to threads, cables, or ropes. The thickness of tensile elements 132 may also vary significantly to range from 0.03 millimeters to more than 5 millimeters, for example. Although one-dimensional materials will often have a cross-section where width and thickness are substantially equal (e.g., a round or square cross-section), some one-dimensional materials may have a width that is greater than a thickness (e.g., a rectangular, oval, or otherwise elongate cross-section). Despite the greater width, a material may be considered one-dimensional if a length of the material is substantially greater than a width and a thickness of the material.
It should be understood that the following figures are for purposes of illustration only, and each of the components described above with respect to
As described above, article 100 may include provisions for securing the foot into article 100. Referring to
In another embodiment, a user may adjust first fastener 124 to remove a foot from article 100 and transition article 100 from the secured state to the open state. One embodiment of this transition process is depicted in the sequence of
It should be understood that the different portions of first fastener 124 can vary in geometry, length, or width. For example, first fastener 124 may be wider or narrower along different portions. However, as shown in
For purposes of reference, as shown in
Furthermore, referring to
The first material and the second material of first fastener 124 as discussed above can be made of various materials, including Teflon loops, polyester hooks, Velcro, glass backing, and other touch fasteners. In one embodiment, the bond formed between the hook and loop materials can provide additional strength to fastening system 120 as the pulling forces can be spread evenly across all hooks. In some embodiments, the materials of hook portions and/or loop portions may be integrally formed with the material of first fastener 124. However, in other embodiments, the materials comprising hook portion and/or loop portion may be separately joined or attached to the material of first fastener 124. Outer side 502 of first fastener 124 may comprise a variety of different materials, as discussed above with reference to materials comprising upper 102.
Thus, first fastener 124 can be fed through and extend through the receptacles of fastening system 120, such that first looping section 198 contacts and engages with first receptacle 144, and second looping section 199 contacts and engages with second receptacle 146. The regions associated with first looping section 198 and second looping section 199 can vary, depending on the extent to which fastening system 120 is tightened or loosened. As a result of the hook and fastening materials mentioned above, when pull tab 142 of first fastener 124 is pulled from one side of article 100 toward the other side of article 100, each side (i.e., lateral side 16 and medial side 18) may be drawn toward the other. Once hook portion 402 comes into contact with loop portion 406, the first and second materials of the loop and hook fastener materials can engage, allowing a tightening and/or securement of first fastener 124, as shown previously in

As described above, in some embodiments, article 100 includes an upper 102 that can comprise several layers. Furthermore, fastening system 120 of article 100 may include various tensile or fastening elements that may contact different layers of upper 102 and/or sole structure 130. Each layer of upper 102 and portions of the fastening system can be designed to extend around or interact with various regions along article 100. This arrangement can be observed in
As noted previously, base layer 116 can be configured to form interior cavity 106 for insertion of a wearer's foot. Disposed adjacent to base layer 116 is an inner liner 800, described above with respect to
Protective layer 118 is depicted as being directly adjacent to external portions of outer liner 112, such that portions of outer liner 112 are covered by protective layer 118. In some embodiments, protective layer 118 and portions of outer liner 112 may be joined to form a unified structural layer, though in other embodiments, protective layer 118 and outer liner 118 may comprise two distinct surfaces.
Furthermore, as shown in
Above outer liner 112, first fastener 124 and second fastener 126 are also depicted. As shown in
Some embodiments of article 100 include provisions that permit the various components or elements of fastening system 120 to operate in conjunction with one another. As mentioned above, in different embodiments, tensile elements 132 and first fastener 124 may intersect or be bridged via second receptacle 146. In other embodiments, the intersection region may comprise another element, different from second receptacle 146, or tensile elements 132 and first fastener 124 may be directly joined without a separate intersecting element. In one embodiment, first fastener 124 and tensile elements 132 may be integrated into a single system. Thus, in some embodiment, the fastening system may be configured to provide multiple directions of stretch-resistance with minimum adjustment. In other words, a force exerted along first fastener 124 can also exert a force along tensile elements 132 in some embodiments. The parallel operation of both elements (i.e., first fastener 124 and tensile elements 132) of fastening system 120 will be discussed in further detail below with respect to
During walking, running, or other ambulatory activities, a foot within the interior cavity of an article may tend to stretch upper 102. That is, many of the material elements forming upper 102 may stretch when placed in tension by movements of the foot. Although tensile elements 132 may also stretch, tensile elements 132 generally stretch to a lesser degree than the other material elements forming upper 102 (e.g., base layer 116, inner liner 800, and/or outer liner 112, shown in
In order to better appreciate the utility of tensile elements 132 in fastening system 120, an exposed portion of upper 102 is depicted in
As shown in
In some embodiments, loops 170 and strap portion 962 may be formed of materials similar to those described for tensile elements 132, though in other embodiments, other textiles, knitted or woven elements, or materials may be used. In one embodiment, the materials for different portions can be configured depending on the amount of friction or resistance desired between tensile elements 132 and loops 170.
Thus, in some embodiments, vamp portion 11 of upper 102 may be configured to resist stretch in the medial-lateral direction as a result of tensile elements 132. In other embodiments, vamp portion 11 of upper 102 may be configured to resist stretch along longitudinal axis 22. In one embodiment, due to the diagonal orientation of tensile elements 132, vamp portion 11 of upper 102 may be configured to resist stretch along both lateral axis 20 as well as the direction along longitudinal axis. Thus, when performing a cutting motion (i.e., side-to-side movement of the wearer), tensile elements 132 can assist with resisting sideways movement of the foot to ensure that the foot remains properly positioned relative to article 100. That is, tensile elements 132 may resist stretch in upper 102 that may otherwise allow the foot to roll off of sole structure 130. Accordingly, in one embodiment, tensile elements 132 resist stretch in upper 102 due to cutting motions and ensure that the foot remains properly positioned relative to article 100. Furthermore, when performing a braking motion (i.e., slowing the forward momentum of the wearer), tensile elements 132 can assist with resisting stretch in upper 102 that may allow the foot to slide forward or separate from sole structure 130. Tensile elements 132 can also resist stretch in upper 102 due to flexing of article 100 in the area between forefoot portion 10 and midfoot portion 12.
In the embodiment of
For purposes of convenience, the portion of tensile elements 132 that contact and/or pass through loops 170 may be referred to as pivoting portions 968. The region of tensile elements 132 associated with pivoting portions 968 may change depending on the amount of tension applied along the fastening system (i.e., tensile elements 132 may slide back and forth through loops 170 as tension is applied or removed). Once tensile elements 132 have engaged with loops 170, they may extend upward to join with lower region 182 of second receptacle 146.
For purposes of reference, the portion of tensile elements 132 that contact forefoot edge 966 of upper 102 may be referred to as proximal ends 978, and the portion of tensile elements 132 that exits from loops 170 to join with second receptacle 146 may be referred to as distal ends 974 of tensile elements 132. It should be understood that the lengths of distal ends 974 can vary depending on the tension applied to fastening system 120.
In different embodiments, proximal ends 978 of tensile elements 132 may be attached to article 100 in a variety of ways. In some embodiments, tensile elements 132 may be attached along an underside of upper 102, for example, between upper 102 and a component of sole structure 130, before upper 102 is joined with sole structure 130 during the manufacture of article 100. In one embodiment, tensile elements 132 may be secured by the application of one or more enforcement strips or bonds that join tensile elements 132 to the underside of upper 102 or sole structure 130. Such enforcement strips may comprise techniques known in the art, including but not limited to adhesives (such as a polymer adhesive), or machine or hand-stitching. Loops 170 or strap portion 962 may be joined to upper 102 and/or sole structure 130 using similar techniques or they may be attached in a manner that differs from the attachment of proximal ends 978. In some embodiments, anchor portions (similar to anchor portion 168 discussed above with respect to
In some embodiments, fastening system 120 may include provisions for securing one or more tensile elements 132, and/or for routing tensile elements 132 in a specific orientation. For example, in some embodiments, tensile elements 132 may contact or engage with an anchor element 926. In
In different embodiments, similar to loops 170, anchor element 926 may comprise materials similar to that of tensile elements 132 or materials that are substantially different. In one embodiment, the materials for different portions of anchor element 926 can be configured depending on the amount of resistance or anchoring strength desired between tensile elements 132 and anchor element 926.
As noted above with respect to first fastener 124, it should be understood that other portions of fastening system 120 may comprise fixed or permanent attachment regions, while other portions may comprise free or adjustable regions. For example, tensile elements 132 may include regions where tensile elements 132 are fixedly attached to upper 102 in some embodiments. In addition, in some embodiments, tensile elements 132 may include regions where tensile elements 132 are free or unattached to another element of article 100. In
It should be understood that in other embodiments, fewer or no tensile elements 132 may be attached to upper 102. In some embodiments, the substantial entirety of a tensile element may be free to move. In another embodiment, the substantial entirety or majority of a tensile element may be joined or fixedly attached to a portion of the article. Furthermore, areas of fixed attachment may occur independent of the presence of an anchor element 926
Thus, in one embodiment, first region 928 is demarcated from second region 930 by anchor element 926 In some embodiments, upon engaging with anchor element 926 tensile elements 132 may be drawn or disposed closer toward a neighboring tensile element. For example, in
Thus, in some embodiments, two or more tensile elements 132 may group or cluster together as they approach medial side 18. In one embodiment, there may be an even number of tensile elements 132, and a pairing can occur between the tensile elements that are disposed directly adjacent to one another. In the embodiment of
Fastening system 120 may include provisions for tensile elements 132 to be guided or routed along different areas of upper 102. For example, in
In first magnified area 938, first pair 932, second pair 934, and third pair 936 are shown as they engage with lower region 182 of second receptacle 146. Lower region 182 may comprise various materials, including textiles and/or plastic or relatively rigid materials. Furthermore, lower region 182 may be further reinforced and bonded along second receptacle 146 by stitching or other attachment methods.
As shown in second magnified area 940, in some embodiments, each of the pairs of tensile elements 132 can form a looping or clasping configuration along an interior 948 of lower region 182. Thus, portions of proximal ends 978 of tensile elements 132 may join or be inserted within an interior 948 of second receptacle 146. In second magnified area 940, a first loop region 942, a second loop region 944, and a third loop region 946 of tensile elements 132 are shown. First loop region 942 may comprise the merging of first element 904 and second element 906, second loop region 944 may comprise the merging of third element 908 and fourth element 910, and third loop region 946 may comprise the merging of fifth element 912 and sixth element 914. In other words, although six tensile elements 132 are present along vamp portion 11, upon engagement with second receptacle 146, each pair of tensile elements 132 may be revealed to be formed from a single or continuous strand. In other embodiments, more than two, or all, of tensile elements 132 may comprise a single strand. However, in another embodiment, each tensile element 132 may comprise an individual strand, and be attached separately to second receptacle 146.
In some embodiments, first loop region 942, second loop region 944, and third loop region 946 of tensile elements 132 may contact, engage, or otherwise extend around a hook or anchoring protrusion within second receptacle 146. For example,
As another example, one or more apertures may be utilized to receive tensile elements 132, such that the tensile elements extend through one or more apertures disposed within second receptacle 146. Hook portions and apertures provide only a few examples of a strand-receiving element with which tensile elements 132 may engage. In other configurations of article 100, grooves, tunnels, or metal or textile loops may be utilized in place of hook portions, or grommets may define the apertures. Accordingly, distal ends 974 may engage with a variety of strand-receiving elements in second receptacle 146.
Also shown in second magnified area 940 is an enlarged view of upper region 180 of second receptacle 146. As noted above with respect to
In different embodiments, the engagement or association of different components of fastening system 120 with one another can allow a user to alter the tension throughout multiple regions of article 100 with a single and relatively swift adjustment. Thus, in one embodiment, the interrelationship of first fastener 124 with tensile elements 132 can provide a user with an enhanced ability to increase stretch-resistance over a large proportion of upper 102 through a minimum number of adjustment steps. For example, as described above, distal ends 974 tensile elements 132 are anchored or secured along one end of second receptacle 146, and second looping section 199 of first fastener 124 can engage or be secured along another end of second receptacle 146, creating an intersection point between the different elements.
Referring to
Furthermore, some or substantially all of pulling force 1000 may also be transmitted or distributed along to tensile elements 132. As second looping section 199 passes through second receptacle 146 and exerts an upward force, distal ends 974 of tensile elements 132 anchored within the lower portion of second receptacle 146 may be tugged or pulled upward. Pulling force 1000 may further be transmitted or distributed to the diagonally disposed tensile elements 132 via the pivoting portions (shown in
In
Furthermore, it should be understood that depending upon the specific configuration of article 100 and the intended use of article, base layer 116, inner liner 800, outer liner 112, and/or protective layer 118 (discussed above with reference to
In different embodiments, changing the locations where first fastener 124, tensile elements 132, first receptacle 144, and/or second receptacle 146 are secured can change the direction of tension or force provided by fastening system 120. In some embodiments, fastening system 120 can be configured apply a circumferential force or hoop stress about heel portion 14 of article 100, for example. In other embodiments, fastening system 120 may be oriented to apply tension in other parts of article 100.
