[0001] This application is a divisional of application number 201910791597.9, filed on April 22, 2015, entitled "Article of Footwear Incorporating a Lens Knit Structure."

[0002] Application number 201910791597.9, filed on April 22, 2015, entitled "Article of Footwear Incorporating a Lens Knit Structure" is a divisional of application number 201510191848.1, filed on April 22, 2015, entitled "Article of Footwear Incorporating a Lens Knit Structure." TECHNICAL FIELD

[0003] The present invention relates generally to articles of footwear, and in particular, to articles of footwear incorporating knitted components. BACKGROUND

[0004] Conventional articles of footwear generally include two primary elements: an upper and a sole structure. The upper is secured to the sole structure and forms a void on the interior of the footwear to comfortably and securely receive a foot. The sole structure is secured to a lower region of the upper, positioned between the upper and the ground. In athletic footwear, for example, the sole structure can include a midsole and an outsole. The midsole often includes a polymer foam material that attenuates ground reaction forces during walking, running and other ambulatory activities to reduce stress to the foot and leg. In addition, the midsole can include fluid-filled chambers, plates, moderators or other elements that further attenuate forces, provide stability, or otherwise influence foot motions. The outsole is secured to an underside of the midsole and provides a ground-engaging portion of the sole structure formed from a durable, wear-resistant material such as rubber. The sole structure can also include a sockliner positioned within the void and proximate to an underside of the foot to enhance footwear comfort.

[0005] The upper generally extends over the instep and toe regions of the foot, along the medial and lateral sides of the foot, under the foot, and around the heel region. In some articles of footwear, such as basketball shoes and boots, the upper can extend upward and around the ankle to provide support or protection to the ankle. An entrance to the void on the interior of the footwear is typically provided by an ankle opening in the heel region of the footwear. A lacing system is often incorporated into the upper to adjust the fit of the upper, to allow entry and removal of the foot from the void within the upper. The lacing system also permits the wearer to modify certain dimensions of the upper, particularly the girth, to accommodate feet with different dimensions. In addition, the upper can include a tongue that extends under the lacing system to enhance the adjustability of the footwear, and the upper can incorporate a heel counter to limit the movement of the heel.

[0006] Various material elements (e.g., fabrics, polymeric foams, polymeric sheets, leathers, synthetic leathers) are conventionally used to manufacture footwear uppers. For example, in athletic footwear, the upper can have multiple layers, each layer including various connected material elements. As an example, the material elements can be selected to impart stretch resistance, abrasion resistance, flexibility, breathability, compression, comfort, and moisture-wicking to different areas of the upper. To impart different properties to different areas of the upper, the material elements are often cut to a desired shape and then often connected together using stitching or adhesive bonding. In addition, the material elements are often connected in a layered configuration to impart multiple properties to the same area. As the number and type of material elements incorporated into the upper increases, the time and expense associated with shipping, storing, cutting, and connecting the material elements also increases. As the number and type of material elements incorporated into the upper increases, scrap from the cutting and stitching processes also accumulates to a greater extent. In addition, an upper having a greater number of material elements can be more difficult to recycle than an upper formed from fewer types and numbers of material elements. Thus, by reducing the number of material elements used for the upper, waste can be reduced, while increasing the manufacturing efficiency and recyclability of the upper. SUMMARY

[0007] Various configurations of articles of footwear can have an upper and a sole structure attached to the upper. The upper can incorporate a knitted component. The knitted component can include a color-shifting property produced by one or more lenticular knit structures arranged throughout the upper of the article of footwear.

[0053] The following discussion and accompanying figures disclose a variety of concepts related to woven components and the manufacture of woven components. Although woven components can be used in a variety of products, articles of footwear incorporating one or more woven components are disclosed below as examples. In addition to footwear, woven components can be used in other types of apparel (e.g., shirts, pants, socks, jackets, underwear), sports equipment (e.g., golf bags, baseball and football gloves, soccer restraining structures), containers (e.g., backpacks, bags), and seat covers for furniture (e.g., chairs, couches, car seats). Woven components can also be used in bed coverings (e.g., sheets, blankets), table coverings, towels, flags, tents, sails, and parachutes. Woven components can be used as technical fabrics for industrial purposes, including structures for automotive and aerospace applications, filtration materials, medical fabrics (e.g., bandages, swabs, grafts), geotextiles for reinforcing embankments, agricultural fabrics for crop protection, and industrial apparel for defense or insulation from heat and radiation. Accordingly, the woven components and other concepts disclosed herein can be incorporated into a variety of products for both personal and industrial purposes.

[0054] Figures 1 to 22 Exemplary embodiments of articles of footwear having uppers incorporating woven components, including lens woven structures, and associated methods of manufacture are illustrated. The uppers incorporate woven components including one or more lens woven structures that provide color-shifting properties to the uppers and articles of footwear. Individual features of any of the woven components described herein can be used in combination or can be provided individually in different configurations for articles of footwear. Further, any of the features can be optional and can not be included in any particular embodiment of a woven component.

[0055] For consistency and convenience, directional adjectives are used throughout this detailed description corresponding to the illustrated embodiments. As used throughout this detailed description and in the claims, the term "longitudinal" refers to a direction extending a length or long axis of an article. In some cases, the longitudinal direction can extend from a forefoot region to a heel region of the article. Also, as used throughout this detailed description and in the claims, the term "lateral" refers to a direction extending a width or short axis of the article. In other words, the lateral direction can extend between a medial side and a lateral side of the article. Further, as used throughout this detailed description and in the claims, the term "vertical" refers to a direction generally perpendicular to the lateral and longitudinal directions. For example, in cases where the article is laid flat on a ground surface, the vertical direction can extend upward from the ground surface. It will be understood that each of these directional adjectives can be applied to various components of the article, including the upper, woven components, and / or the sole structure, as well as portions thereof.

[0056] Figures 1 to 6 An exemplary embodiment of an article of footwear 100 (also simply referred to as article 100) is illustrated. In some embodiments, the article of footwear 100 can include a sole structure 110 and an upper 120. Although the article 100 is illustrated in a general configuration suitable for running, the concepts associated with the article 100 can also be applied to a variety of other athletic footwear types, including, for example, soccer shoes, baseball shoes, basketball shoes, cycling shoes, football shoes, tennis shoes, training shoes, walking shoes, and hiking boots. The concepts can also be applied to footwear types that are generally considered to be non-athletic, including dress shoes, loungers, sandals, and work boots. Accordingly, the concepts disclosed with respect to the article 100 can be applied to a wide variety of footwear types.

[0057] For purposes of reference, the article 100 can be divided into three general regions: a forefoot region 10, a midfoot region 12, and a heel region 14, as shown in FIG. 1. The forefoot region 10 generally includes portions of the article 100 corresponding with the toes and the front of the foot, the midfoot region 12 generally includes portions of the article 100 corresponding with the arch area of the foot, and the heel region 14 generally includes portions of the article 100 corresponding with the back of the foot. The boundaries of these regions are not strictly defined, and the regions can overlap. Figure 1 Figure 2 and Figure 3 ​As shown in the diagram. The forefoot region 10 generally includes the portion of article 100 corresponding to the toes and the joints connecting the metatarsals and phalanges. The midfoot region 12 generally includes the portion of article 100 corresponding to the arch region of the foot. The heel region 14 generally corresponds to the posterior portion of the foot, including the calcaneus. Article 100 also includes a lateral surface 16 and a medial surface 18, which extend through each of the forefoot region 10, the midfoot region 12, and the heel region 14 and correspond to opposite sides of article 100. More specifically, the lateral surface 16 corresponds to the lateral region of the foot (i.e., the surface facing away from the other foot), and the medial surface 18 corresponds to the medial region of the foot (i.e., the surface facing towards the other foot). The forefoot region 10, the midfoot region 12, and the heel region 14, as well as the lateral surface 16 and the medial surface 18, are not intended to define precise areas of article 100. Rather, the forefoot area 10, midfoot area 12, heel area 14, outer side 16, and inner side 18 are intended to represent the general areas of article 100 to aid in the following discussion. In addition to article 100, the forefoot area 10, midfoot area 12, heel area 14, outer side 16, and inner side 18 can also be applied to the sole structure 110, upper 210, and their various components.

[0058] exist Figure 4 The diagram illustrates the description. Figures 1 to 15 An exemplary coordinate system for an embodiment of article 100 shown in the figure, wherein a longitudinal direction 2 extends along article 100 between the forefoot area 10 and the heel area 14 of article 100, a transverse direction 4 extends along article 100 between the outer side 16 and the inner side 18, and a vertical direction 6 extends along article 100 between the sole structure 110 and the top of article 100.

[0059] In an exemplary embodiment, the sole structure 110 is attached to the upper 120 and extends between the foot and the ground when the article 100 is worn. In some embodiments, the sole structure 110 may include one or more components, including a sole midsole, an outsole, and / or an insole or insole. In an exemplary embodiment, the sole structure 110 may include an outsole attached to the lower surface of the upper 120 and / or a base portion configured to attach the sole structure 110 to the upper 120. In one embodiment, the outsole may be formed of an abrasion-resistant rubber material with a texture to impart adhesion friction. While this configuration for the sole structure 110 provides an embodiment of a sole structure that can be used with respect to the upper 120, a variety of other conventional or unconventional configurations for the sole structure 110 may also be used. Therefore, in other embodiments, the characteristics of the sole structure 110 or any sole structure used with the upper 120 may be varied.

[0060] For example, in other embodiments, the sole structure 110 can include a midsole and / or insole. The midsole can be secured to an underside of the upper, and in some cases, the midsole can be formed of a compressible polymer foam element (e.g., 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 other cases, the midsole can incorporate plates, moderators, fluid-filled chambers, lasting elements, or motion control members that further attenuate forces, enhance stability, or influence foot motions. In still other cases, the midsole can be formed primarily of fluid-filled chambers that are located within the upper and positioned to extend under the underside of the foot to enhance article comfort.

[0061] In some embodiments, the upper 120 defines a void within the article 100 for receiving and securing a foot relative to the sole structure 110. The void is shaped to receive the foot and extends along a lateral side of the foot, along a medial side of the foot, over the foot, around the heel, and under the foot. The upper 120 includes an outer surface 121 and an opposite, inner surface 122. The outer surface faces outward and away from the article 100, while the inner surface faces inward and defines a majority or a substantial portion of the void within the article 100 for receiving the foot. Moreover, the inner surface can rest against or cover a sock of the foot. The upper 120 can also include a collar 142 that is located in at least the heel region 14 and forms a throat opening 140. Access to the void is provided by the throat opening 140. More particularly, the foot can be inserted into the upper 120 through the throat opening 140 formed by the collar 142, and the foot can be removed from the upper 120 through the throat opening 140 formed by the collar 142. In some embodiments, an instep region 150 extends forward from the collar 142 and the throat opening 140 in the heel region 14 to an area adjacent to the forefoot region 10, over an area corresponding to the instep of the foot in the midfoot region 12.

[0062] In some embodiments, the upper 120 may include a throat portion disposed between the outer side 16 and the inner side 18 of the upper 120, passing through the instep region 150. In an exemplary embodiment, the throat portion may be integrally attached to the portion of the upper 120 passing through the instep region 150 along the outer and inner sides, and is formed by an integrally woven construction together with the portion of the upper 120 passing through the instep region 150 along the outer and inner sides. Thus, as shown, the upper 120 may extend substantially continuously across the instep region 150 between the outer side 16 and the inner side 18. In other embodiments, the throat portion may be discontinuous along the outer and inner sides of the instep region 150, such that the throat portion is movable within an opening between an outer portion and an inner portion on opposite sides of the instep region 150, thereby forming a tongue.

[0063] In some embodiments, the shoelaces 152 extend through a plurality of shoelace receiving members 154 in the upper 120 and allow the wearer to change the size of the upper 120 to fit the foot size. In some embodiments, the shoelaces 152 may extend through shoelace receiving members 154 arranged along either side of the instep region 150. More specifically, the shoelaces 152 allow the wearer to tighten the upper 120 around the foot, and the shoelaces 152 allow the wearer to loosen the upper 120 to facilitate foot entry into and removal from the cavity (i.e., through the throat opening 140). Furthermore, the throat portion of the upper 120 in the instep region 150 extends below the shoelaces 152 to enhance the comfort of the article 100. The shoelaces 152 are used together with the article 100 in… Figure 1 The image shows the shoelaces 152, which have been omitted for clarity in the remaining images. In other configurations, the upper 120 may include additional elements such as (a) a heel counter in the heel area 14 for enhanced stability, (b) a foot protector in the forefoot area 10 made of abrasion-resistant material, and (c) logos, trademarks, and notices with care instructions and material information.

[0064] Many conventional footwear uppers are formed from multiple material elements (e.g., fabric, polymeric foam, polymeric sheeting, leather, synthetic leather) that are connected, for example, by stitching or bonding. In contrast, in some embodiments, a majority of the upper 120 is formed from a knitted component 130 that will be discussed in greater detail below. For example, the knitted component 130 can be manufactured through a flat knitting process and extends along both the lateral side 16 and the medial side 18, over the forefoot region 10, and through each of the forefoot region 10, the midfoot region 12, and the heel region 14 around the heel region 14. In example embodiments, the knitted component 130 forms substantially all of the upper 120, including a majority or a relatively large portion of the exterior surface 121, and the interior surface 122, thereby defining a portion of the void within the upper 120. In some embodiments, the knitted component 130 can also extend under the foot. In other embodiments, however, a strobel sock or sheet of thin, shoe-like material is secured to the knitted component 130 to form an attached portion of the upper 120 that extends under the foot for attachment with the sole structure 110.

[0065] Furthermore, in this embodiment, the seam 160 extends generally vertically in a downward direction from the collar 142 along the lateral side 16 toward the sole structure 110 to connect the edges of the knitted component 130. In other embodiments, the seam 160 can be arranged in a generally similar manner on the medial side 18. In still other embodiments, the seam 160 can instead extend vertically in a downward direction from the collar 142 at the rear of the article 100 through the heel region 14 toward the sole structure 110.

[0066] While seams can be present in the knitted component 130, a majority of the knitted component 130 has a generally seamless configuration. Furthermore, the knitted component 130 can be formed from a unitary knitted construction. As used herein, a knitted component (e.g., the knitted component 130) is defined as being formed from a "unitary knitted construction" when formed as a one-piece element through a knitting process. That is, the knitting process generally forms the various features and structures of the knitted component 130 without the need for additional significant manufacturing steps or processes. The unitary knitted construction can be used to form a knitted component having structures or elements that include one or more courses of yarn, string, or other knitted material that are connected such that the structures or elements include at least one common course (i.e., share a common yarn) and / or include courses that are generally continuous between each of the structures or elements. Using this arrangement, a one-piece element of the unitary knitted construction is provided.

[0067] Although multiple portions of the knitted component 130 can be connected to one another after the knitting process (e.g., edges of the knitted component 130 are connected together), the knitted component 130 is still formed from a unitary knitted construction because the unitary knitted construction is formed as a one-piece knitted element. Further, the knitted component 130 is still formed from a unitary knitted construction when other elements (e.g., laces, logos, trademarks, and signs with care instructions and material information, structural elements) are added after the knitting process.

[0068] In various embodiments, any suitable knitting process can be used to produce the knitted component 130 formed from a unitary knitted construction, including but not limited to: warp or weft knitting processes, including flat knitting knitting processes or circular knitting processes, or any other suitable knitting process for providing a knitted component. Examples of various configurations of knitted components and methods for forming knitted components 130 from a unitary knitted construction are disclosed in one or more of U.S. Patent No. 6,931,762 to Dua; U.S. Patent No. 7,347,011 to Dua et al.; U.S. Patent No. 8,490,299 to Dua et al.; and U.S. Patent No. 8,839,532 to Huffa et al., the disclosures of which are incorporated by reference in their entirety. In example embodiments, a flat knitting knitting process can be used to form the knitted component 130, as will be described in greater detail.

[0069] In various embodiments, an article of footwear can be provided with an upper incorporating a knitted component having a color shifting property. Generally, a color shifting property refers to the characteristic of an element that appears different colors depending on the viewing angle of the element. In example embodiments, the color shifting property can be provided to the article of footwear using a visual effect similar to or inspired by lenticular printing technology. Lenticular printing involves the use of lenses to cause changes in visible images or patterns when viewed from different viewing angles. This lenticular printing technology can be used to create simple animations and visual effects for advertising and other purposes.

[0070] In some embodiments, a knitted component can be provided with a color shifting property by using a lenticular knitted structure. The lenticular knitted structure is configured to present at least two different colors to a viewer when the lenticular knitted structure is viewed from different viewing angles. For example, the lenticular knitted structure can cause the knitted component to appear a first color when viewed from a first viewing angle, but the lenticular knitted structure causes the knitted component to appear a second color different from the first color when viewed from a second viewing angle different from the first viewing angle. Using this configuration, the lenticular knitted structure can change the visual color appearance of the knitted component as the knitted component and / or the viewer move relative to the article of footwear. The change in viewing angle associated with this movement of the knitted component and / or the viewer causes the lenticular knitted structure to present a different color to the viewer, thereby creating a color shifting property to the knitted component and the article of footwear.

[0071] In example embodiments, at least a portion of the woven component 130 can be provided with color-shifting properties by incorporating one or more lens weave structures 132. In such embodiments, the lens weave structure 132 can be in the form of a tubular rib structure. In some cases, the tubular rib structure can be a non-planar structure that extends away from a surface of the woven component 130 and defines a hollow tube formed by the coextensive and overlapping woven layers proximate to the tube. In other cases, the tubular rib structure can include additional components disposed within the tube, as will be described in greater detail below.

[0072] In some embodiments, at least a portion of the woven component 130 can include areas on the outer surface 121 of the woven component that extend between the lens weave structures 132, i.e., areas between adjacent tubular rib structures forming the lens weave structures 132. In example embodiments, a base portion 136 of the woven component 130 is disposed between the lens weave structures 132. In some cases, the base portion 136 can be pliable, elastic, and resilient and assist in the stretching of the woven component 130.

[0073] The properties imparted to areas of the woven component 130 by a particular type of yarn depend in part on the materials forming the various filaments and fibers within the yarn. For example, cotton provides a soft hand, a natural aesthetic, and biodegradability. Spandex and stretch polyester each provide considerable stretch and recovery, with stretch polyester also providing recyclability. Rayon provides a high sheen and moisture wicking. Yarn also provides high moisture wicking in addition to insulating properties and biodegradability. Nylon is a durable and abrasion resistant material with a relatively high strength. Polyester is a hydrophobic material that also provides a relatively high durability. In addition to the materials, other aspects of the yarns selected for the woven component 130 can influence the properties of the upper 120. For example, the yarns forming the woven component 130 can include individual filaments each formed of a different material. Further, the yarns can include filaments each formed of two or more different materials, such as a bicomponent yarn in which the filaments have a sheath-core configuration or are formed of two halves of different materials. Different degrees of twist and crimp, as well as different deniers, can also influence the properties of the upper 120. Thus, the two materials forming the yarns and other aspects of the yarns can be selected to impart a variety of properties to separate areas of the upper 120.

[0074] In some configurations of the woven component 130, the material forming the yarns can be non-meltable or meltable. For example, the non-meltable yarns can be formed substantially from a thermoset polyester material, and the meltable yarns can be formed at least partially from a thermoplastic polyester material. When the meltable yarns are heated and fused to the non-meltable yarns, this process can have the effect of hardening or stiffening the structure of the woven component 30. Further, the use of meltable yarns to connect multiple portions of non-meltable yarns can have the effect of fixing or locking the relative positions of the non-meltable yarns within the woven component 130, imparting resistance to stretching and stiffness. That is, the portions of non-meltable yarns can not slide relative to one another when fused with the meltable yarns, preventing the woven component 130 from buckling or permanently stretching due to relative movement of the woven structure. Another feature of using meltable yarns in portions of the woven component 130 relates to limiting unraveling if a portion of the woven component 130 becomes damaged or one of the non-meltable yarns breaks. Thus, regions of the woven component 130 can be configured with both meltable and non-meltable yarns within the woven structure.

[0075] In example embodiments, the lens weave structure 132 can provide the color shifting properties to the woven component 130 by incorporating two or more types of yarns used to weave the lens weave structure 132. For example, in embodiments in which the lens weave structure 132 is in the form of a tubular rib structure, different portions of the lens weave structure 132 can include different types of yarns along each side of the tubular rib structure. In one embodiment, a first portion 133 of the lens weave structure 132 disposed on one side of the tubular rib structure can be woven using a first yarn, and a second portion 134 of the lens weave structure 132 disposed on an opposite side of the tubular rib structure can be woven using a second yarn that is different from the first yarn. In some cases, the types of yarns can change color to provide the color shifting properties to the woven component 130. In other cases, the types of yarns can change texture or denier to provide the color shifting properties to the woven component 130.

[0076] Referring to Figure 1 In this embodiment, the woven component 130 includes a plurality of lens weave structures 132 in the form of tubular rib structures extending approximately along the transverse direction between the lateral side 16 and the medial side 18 through a portion of the forefoot region 10, the midfoot region 12, and the heel region 14. Each lens weave structure 132 includes a first portion 133 disposed on one side of the tubular rib structure at the forefoot region 10 facing the front of the article 100, and a second portion 134 disposed on an opposite side of the tubular rib structure at the heel region 14 facing the back or rear of the article 100. Using this configuration, the color shifting properties of the woven component 130 caused by the lens weave structure 132 can change when the article 100 is viewed from different viewing angles.

[0077] Furthermore, in example embodiments, at least a portion of the woven component 130 can include the lens weave structure 132 having different orientations. For example, in areas of the woven component 130 disposed on the lateral side 16 and the medial side 18 proximate the heel region 14, the lens weave structure 132 transitions from being oriented approximately along the lateral direction to being oriented approximately along the longitudinal direction. The medial side 18 can be viewed with particular reference to the medial side view illustrated in Figure 2 Figure 3 The lateral side 16 can be viewed with particular reference to the lateral side view illustrated in

[0078] Furthermore, due to the different orientations of the lens weave structure 132 disposed approximately along the longitudinal direction, the viewing angle of the color shifting properties can be different than the viewing angle of the lens weave structure 132 disposed approximately along the lateral direction. Using this configuration, different areas of the woven component 130 and the article 100 can have color shifting properties throughout various viewing angles such that different areas of the woven component 130 appear to shift color individually or at different times during movement when the article 100 and / or the viewer move relative to one another.

[0079] Figures 5 to 6 two representative views of the color shifting properties of the woven component 130 caused by the lens weave structure 132 when the article 100 is viewed from two different viewing angles. In this embodiment, the woven component 130 includes the lens weave structure 132 having a first portion 133 formed using a first yarn and a second portion 134 formed using a second yarn. As mentioned above, in various embodiments, the first yarn and the second yarn can be different types that provide different visual effects. For example, in this embodiment, the first yarn can be associated with a first color and the second yarn can be associated with a second color that is different than the first color. However, in other embodiments, the first yarn and the second yarn can be types having different characteristics that can cause visual color shifting effects.

[0080] Reference is now made to Figure 5 ​In this embodiment, the article 100 is viewed by a viewer from a first viewing angle 500. The first viewing angle 500 is approximately positioned at the front of the article 100 and is oriented at least partially along the longitudinal direction of the article 100. From the first viewing angle 500, the article 100 appears to have woven components 130 of a first color. In an exemplary embodiment, the first color is the same as the first yarn used to weave the first portion 133 of the lens weave structure 132. That is, from the first viewing angle 500, the first portion 133 of each lens weave structure 132 is aligned so as to face the viewer. Using this orientation, the first yarn used to form the first portion 133 of the lens weave structure 132 is visible from the first viewing angle 500, while the second yarn used to form the second portion 134 of the lens weave structure 132 is arranged on the opposite side and is obscured from view from the first viewing angle 500. In this case, the properties of the first yarn (i.e., type, color, texture, denier, etc.) of the first portion 133 forming the lens weave structure 132 are mainly the cause of the visual effect of the weave component 130 displaying the first color from the first viewing angle 500.

[0081] Now refer to Figure 6 In this implementation scheme, object 100 is viewed by a viewer from a second perspective 600. The second perspective 600 and... Figure 5 The first viewing angle 500 shown is different and can be oriented at least partially along the longitudinal direction approximately arranged behind the article 100. From the second viewing angle 600, the article 100 presents woven components 130 that appear to have a second color, which is different from the first color that appears to the viewer from the first viewing angle 500. In an exemplary embodiment, the second color is the same as the second yarn used to weave the second portion 134 of the lens weave structure 132. That is, from the second viewing angle 600, the second portion 134 of each lens weave structure 132 is aligned so as to face the viewer. Using this orientation, the second yarn used to form the second portion 134 of the lens weave structure 132 is visible from the second viewing angle 600, while the first yarn used to form the first portion 133 of the lens weave structure 132 visible from the first viewing angle 500 is now arranged on the opposite side and is obscured from view from the second viewing angle 600. In this case, the properties of the second yarn (i.e., type, color, texture, denier, etc.) of the second portion 134 forming the lens weave structure 132 are primarily the cause of the visual effect of the weave component 130 displaying a second color from the second viewing angle 600. Using this configuration, the color-changing properties of the weave component 130 can be provided by the lens weave structure 132.

[0082] Furthermore, in some embodiments, the base portion 136 of the braided component 130 may be visible from both a first viewing angle 500 and a second viewing angle 600. The base portion 136 may be formed using a yarn type (including yarn color) substantially similar to any of the first or second yarns forming the first portion 133 or the second portion 134 of the lens braid structure 132. Using this configuration, the type of yarn used to form the base portion 136 can also be assisted by providing a first or second color visual effect to the braided component 130 from either the first viewing angle 500 or the second viewing angle 600. However, in other embodiments, the base portion 136 may be formed using a different yarn type (including different yarn colors) than any of the first or second yarns forming the first portion 133 or the second portion 134 of the lens braid structure 132. Using this configuration, the base portion 136 can provide a visual effect contrasting with either the first or second color.

[0083] In other embodiments, the lens braids 132 may be closely spaced such that the base portion 136 is not initially partially or entirely visible from either the first viewing angle 500 or the second viewing angle 600. However, when the braided portion 130 is stretched, the base portion 136 may be exposed between adjacent lens braids 132. Therefore, in these embodiments, the base portion 136 may be formed using a yarn type (including yarn color) that is highly contrasted with the yarn type or color of the first or second yarn forming the first portion 133 or the second portion 134 of the lens braid 132. For example, in one embodiment, the base portion 136 may be formed using yarn with reflective or retroreflective properties.

[0084] The braided component 130 can be manufactured using the configuration described above with any suitable machine, appliance, and technique. For example, in some embodiments, the braided component 130 can be manufactured using a braiding machine such as... Figure 7 The knitting machine 700 shown is for automated manufacturing. The knitting machine 700 can be any suitable type, such as a flat knitting machine. However, it will be understood that the knitting machine 700 can have another type in different embodiments without departing from the scope of this disclosure.

[0085] like Figure 7In the embodiment shown, the knitting machine 700 can include a front needle bed 701 having a plurality of front needles 703 and a back needle bed 702 having a plurality of back needles 704. The front needles 703 can be arranged in a common plane, and the back needles 704 can be arranged in a different common plane that intersects the plane of the front needles 703. The front needle bed 701 and the back needle bed 702 can be angled with respect to one another. In some embodiments, the front needle bed 701 and the back needle bed 702 can be angled such that they form a V-bed. The knitting machine 700 can also include one or more feeders configured to move over the front needle bed 701 and the back needle bed 702. In Figure 7 In the embodiment shown, a first type of feeder 720 and a second type of feeder 722 are indicated. The knitting machine 700 also includes a carriage 730 that moves across the needle beds and assists in moving the feeders relative to the needle beds. In this embodiment, the knitting machine 700 is shown with a plurality of first type of feeders 720 and at least one second type of feeder 722. When the first type of feeders 720 move, the feeders 720 can deliver yarn to the front needles 703 and / or the back needles 704 to form a knitted component including the knitted component 130 using one or more of looping, tucking, or floating the yarn. When the second type of feeder 722 moves, the second type of feeder 722 can deliver yarn to the front needles 703 and / or the back needles 704 to perform one or more of looping, tucking, or floating. In some embodiments, the second type of feeder 722 can be a combination feeder that can additionally be configured to inlay yarn. In an exemplary embodiment, the second type of feeder 722 can deliver a pull-resistant element 724 to be inlaid within the knitted component 130.

[0086] A pair of rails including a front rail 710 and a back rail 711 can extend above and parallel to the intersection of the front needle bed 701 and the back needle bed 702. The rails can provide attachment points for the feeders. The front rail 710 and the back rail 711 can each have two sides, including a front side 712 and a back side 714. Each of the front side 712 and the back side 714 can accommodate one or more feeders. As depicted, the back rail 711 includes two feeders 720 on opposite sides, and the front rail 710 includes a feeder 722. Although two rails are depicted, additional configurations of the knitting machine 700 can incorporate additional rails to provide attachment points for more feeders.

[0087] The feeders can move along the front rail 710 and the back rail 711 to supply yarn to the needles. As Figure 7As shown in FIG. 7, the feeders are provided with yarn for knitting by routing the yarn through the yarn guides 728 to one or more bobbins of the feeders. Although not depicted, additional bobbins can be used to provide the feeders with yarn in a generally similar manner. Suitable knitting machines including conventional feeders and combination feeders for the knitting machine 700 and associated methods of knitting using the machine to form knitted components are described in U.S. Patent No. 8,522,577 to Huffa, the disclosure of which is incorporated by reference in its entirety.

[0088] Figure 8 An exemplary process 800 of knitting a knitted component including a knitted component 130 having a lens knit structure 132 is illustrated. In one embodiment, the process 800 can include one or more steps that can be repeated to form a complete knitted component. The order of the steps is exemplary, and in other embodiments, Figure 8 Additional or different steps not shown in FIG. 8 can be included to knit the knitted component. In a first step 802, a base portion 136 of the knitted component 130 can be knitted using a first yarn. Next, in a step 804, a first portion 133 of the tubular rib structure forming the lens knit structure 132 can be knitted using a second yarn. In a step 806, a second portion 134 of the tubular rib structure forming the lens knit structure 132 can be knitted using a third yarn. As mentioned above, in exemplary embodiments, the second yarn used in step 804 and the third yarn used in step 806 can be different types of yarn (including yarns having different characteristics including, but not limited to, color, texture, denier, or other qualities) to provide the knitted component 130 with the color shifting properties resulting from the lens knit structure 132.

[0089] In some embodiments, the first yarn used in step 802 to form the base portion 136 can be different from one or both of the second and third yarns. In other embodiments, the first yarn used in step 802 can be similar to either of the second and third yarns.

[0090] In some embodiments, the tensile element 724 can be incorporated, inlaid, or extended into one or more of the tubular rib structures during the overall knitted construction of the knitted component 130. In other words, the tensile element 724 can be incorporated during the knitting process 800 of the knitted component 130. As mentioned above, in exemplary embodiments, the tensile element 724 can be incorporated into the knitted component 130 during the knitting process 800 of the knitted component 130. Figure 8As shown in FIG. 8, the process 800 can include an optional step 808 to inlay a tensile element within one or more of the tubular rib structures forming the lens weave structures 132. In some embodiments, the tensile element 724 can be positioned within the unsecured region of the channel within the tubular rib structure forming the lens weave structure 132. In different embodiments, one or more tensile elements 724 can be incorporated in the woven component 130. For example, in the embodiment shown in FIG. 8, the tensile element 724 can be used to form the lace containment member 154 that forms a loop to contain the lace 152 that passes through the instep region 150. The tensile element 724 can also provide support to the woven component 130 by resisting deformation, stretching, or otherwise providing support to the wearer's foot during running, jumping, or other movements. Figure 1 In the embodiment shown in FIG. 8, the tensile element 724 can be used to form the lace containment member 154 that forms a loop to contain the lace 152 that passes through the instep region 150. The tensile element 724 can also provide support to the woven component 130 by resisting deformation, stretching, or otherwise providing support to the wearer's foot during running, jumping, or other movements.

[0091] Using this configuration, the process 800 can be used to form a plurality of base portions 136 and a plurality of lens weave structures 132 disposed throughout a portion or a substantial portion of the woven component 130 to be incorporated into the upper 120 of the article 100. Generally, the base portion 136 of the woven component 130 can be a portion of connection between one or more elements and / or portions of the woven component 130. The base portion 136 is formed from the unitary woven construction along with the remainder of the woven component 130 and can help to connect different portions together as a one-piece woven element. The woven component 130 can include any suitable number of base portions 136. In different embodiments, the base portion 136 can be a region of the woven component 130 that includes one woven layer. In some embodiments, the base portion 136 can extend between a portion of the woven component and another portion of the woven component 130. In one embodiment, the base portion 136 can extend between one tubular rib structure and another tubular rib structure forming an adjacent lens weave structure 132. In different embodiments, the base portion 136 can extend between one tubular rib structure and another portion of the woven component 130. In another embodiment, the base portion 136 can extend between one tubular rib structure and an edge of the woven component 130. Suitable configurations of the base portion 136 can be in the form of a mesh region, which is described in co-pending and commonly owned U.S. Patent Application Serial No. 62 / 057,264 [Attorney Docket No. 51-3901], filed on September 30, 2014, the disclosure of which is hereby incorporated by reference in its entirety.

[0092] As described above, in some embodiments, the lens weave structure 132 can be formed as a tubular rib structure, which is a region of the woven component 130 constructed by two or more coextending and overlapping weave layers. A weave layer can be a portion of the woven component 130 formed of a woven material, such as a thread, yarn, or cord, and two or more weave layers can be formed by an overall weave construction in such a way as to form a tube or channel in the woven component 130 (considered to be a tubular rib structure). While the sides or edges of the weave layers forming the tubular rib structure can be secured to other layers, the central region is typically unsecured to form a hollow between the two layers of woven material forming each weave layer. In some embodiments, the central region of the tubular rib structure can be configured such that another element (e.g., a tensile element) can be located between and pass through the hollow between the two weave layers forming the tubular rib structure. Suitable tubular rib structures, including or excluding inlaid tensile elements, that can be used to form the lens weave structure 132 are described in the above-incorporated by reference co-pending and commonly owned U.S. Patent Application Serial No. 62 / 057264, filed September 30, 2014 [Attorney Docket No. 51-3901].

[0093] Figures 9 to 11 A series of representative views of a weaving process 800 using the loom 700 to form a portion of the woven component 130 is illustrated. Additional steps or processes, not shown here, can be used to form a complete woven component to be incorporated into an upper of an article of footwear, including the upper 120 of the article 100. Further, only a relatively small segment of the woven component 130 can be shown in order to better illustrate the weave structure of one or more portions of the woven component 130. Moreover, the scale or size of the loom 700 and one or more elements of the woven component 130 can be exaggerated in order to better illustrate the weaving process.

[0094] It should be understood that while the woven component 130 is formed between the front needle bed 701 and the back needle bed 702, for purposes of illustration, the woven component 130 is shown adjacent to the front needle bed 701 and the back needle bed 702 in Figures 9 to 11 In the Figures 9-11 , the front and back needles are not depicted for purposes of clarity. Also, while one track and a limited number of feeders are depicted, additional tracks, feeders, and spools can be used. Thus, the general structure of the loom 700 is simplified for purposes of explaining the weaving process.

[0095] Referring to Figure 9FIG. 7 illustrates a portion of a braiding machine 700. In this embodiment, the braiding machine 700 can include a first feeder 900, a second feeder 902, and a third feeder 904. In other embodiments, additional or fewer feeders can be used and can be located on the front or back side of the front rail 710 and / or the back rail 711. In this embodiment, a first yarn 901 passes through the first feeder 900 from a spool (not shown) and an end of the first yarn 901 extends outward from a dispensing tip at the end of the first feeder 900. Any type of yarn (e.g., filament, thread, cord, tape, cable, warp, or rope) can pass through the first feeder 900. A second yarn 903 similarly passes through the second feeder 902 and extends outward from a dispensing tip at the end of the second feeder 902. In an example embodiment, a third yarn 905 also similarly passes through the third feeder 904 and extends outward from a dispensing tip at the end of the third feeder 904. In some embodiments, the first yarn 901, the second yarn 903, and the third yarn 905 can be used to form one or more portions of the braided component 130, as will be discussed further below.

[0096] In an example embodiment, each of the first yarn 901, the second yarn 903, and the third yarn 905 can be a different yarn type associated with different properties, including but not limited to: color, texture, denier, or other qualities, to provide the braided component 130 with the color-shifting properties caused by the lens weave structure 132. In some embodiments, the first yarn 901, the second yarn 903, and the third yarn 905 can be the same yarn type, but can be dyed or otherwise colored differently to provide the braided component 130 with the color-shifting properties caused by the lens weave structure 132. Figure 9 In the example embodiment, the first feeder 900 can use the first yarn 901 to braid the base portion 136 of the braided component 130. Each pass of the first feeder 900 across the needle beds 701, 702 of the braiding machine 700 creates a course of intermeshing loops formed by the first yarn 901. Multiple passes of the first feeder 900 can be used to braid the base portion 136 with a desired number of courses. Next, according to step 804 of the process 800, Figure 10 FIG. 7 illustrates a portion of a braiding machine 700. In this embodiment, the braiding machine 700 can include a first feeder 900, a second feeder 902, and a third feeder 904. In other embodiments, additional or fewer feeders can be used and can be located on the front or back side of the front rail 710 and / or the back rail 711. In this embodiment, a first yarn 901 passes through the first feeder 900 from a spool (not shown) and an end of the first yarn 901 extends outward from a dispensing tip at the end of the first feeder 900. Any type of yarn (e.g., filament, thread, cord, tape, cable, warp, or rope) can pass through the first feeder 900. A second yarn 903 similarly passes through the second feeder 902 and extends outward from a dispensing tip at the end of the second feeder 902. In an example embodiment, a third yarn 905 also similarly passes through the third feeder 904 and extends outward from a dispensing tip at the end of the third feeder 904. In some embodiments, the first yarn 901, the second yarn 903, and the third yarn 905 can be used to form one or more portions of the braided component 130, as will be discussed further below.

[0097] After the desired number of courses of the second yarn 903 have been braided by the second feeder 902, the braiding process 800 can proceed to step 806 to braid the second portion 134. As Figure 11As shown in FIG. 12, the third feeder 904 is used to weave the third yarn 905 to form one or more courses that form the second portion 134 of the tubular rib structure, forming opposite sides of the lens weave structure 132. The optional step 808 of inlaying a tensile element can then be performed to place the tensile element 724 within the tubular rib structure.

[0098] Figures 9 to 11 The exemplary weaving process 800 has been illustrated without specific regard to the order in which the weaving is performed with respect to any particular set of needles associated with the front needle bed 701 and / or the back needle bed 702. Figure 12 and Figure 13 Exemplary weave or loop diagrams illustrating the order in which each of the portions of the woven component 130 (including the base portion 136, the first portion 133, and the second portion 134) can be formed with respect to a particular needle bed are illustrated. However, it should be noted that, Figure 12 and Figure 13 One exemplary configuration implementing the process 800 is illustrated. Other configurations can be readily obtained in accordance with the principles of the application described herein to form other lens weave structures to provide a color shifting property to an article.

[0099] In Figure 12 One embodiment of the first weave diagram 1200 illustrated in FIG. 12, the base portion 136 can be formed using the back needle bed 702 from the first yarn 901, followed by the first portion 133 of the lens weave structure 132 being formed from the second yarn 903, and the second portion 134 of the lens weave structure 132 being formed using a combination of the back needle bed 702 and the front needle bed 701 from the third yarn 905, and another base portion 136 can be formed using the back needle bed 702 from the first yarn 901. The following discussion describes Figures 12-13 The weaving process illustrated schematically in FIG. 12, and it will be understood that the front needle bed 701 and the back needle bed 702 referred to in this discussion are in Figure 7 are illustrated schematically in FIG. 12.

[0100] Referring again to Figure 12After the final course 1202 of the base portion 136 is formed using the first yarn 901, a linking course 1204 can be extended between the back needle bed 702 and the front needle bed 701. Next, one or more courses can be knitted on the front needle bed 701. For example, the courses forming the first portion 133 of the lens knit structure 132 can be formed in a similar manner as courses 1206 knitted on the front needle bed 701 using the second yarn 903. Next, after the final course 1208 of the first portion 133 is knitted on the front needle bed 701 using the second yarn 903, additional courses forming the second portion 134 of the lens knit structure 132 can be formed in a similar manner on the front needle bed 701 as courses 1210 using the third yarn 905. After the desired number of courses of the second portion 134 are formed and knitted on the front needle bed 701, the third yarn 905 can be used to knit courses 1212 using the back needle bed 702. For example, the courses 1212 can form the last course of the second portion 134 of the lens knit structure 132, which closes the tubular rib structure and forms the hollow channel. After the courses 1212 complete the lens knit structure 132, another linking course 1214 can be extended between the back needle bed 702 and the front needle bed 701, which interlinks with the previous courses on the front needle bed 701 and the back needle bed 702. By using a knit stitch at the linking course 1214 extending between the back needle bed 702 and the front needle bed 701, the third yarn 905 forming the second portion 134 of the lens knit structure 132 can be prepared to be associated with additional courses forming another base portion 136 using the back needle bed 702 from the first yarn 901 by transferring the knitted component 130 to the back needle bed 702 at step 1216 and repeating the above described process until the knitted component 130 is complete.

[0101] In various embodiments, a different number of courses can be knitted on one or both of the front needle bed 701 and the back needle bed 702 in order to change the shape and / or size of the tubular rib structure forming the lens knit structure 132. In some cases, by increasing or decreasing the number of courses knitted on the back needle bed 702 and / or the front needle bed 701, the size of the tubular rib structure can be correspondingly enlarged or reduced. In other cases, by increasing the number of courses knitted on one (relative to the other) of the back needle bed 702 or the front needle bed 701, the shape of the tubular rib structure can be changed. For example, by increasing the number of courses knitted on the back needle bed 702, the shape of the tubular rib structure can be changed so as to round the curvature on the inner surface 122 of the knitted component 130 similar to the curvature on the outer surface 121 of the knitted component 130. Further, by increasing or decreasing the number of courses knitted using each of the second yarn 903 and / or the third yarn 905, the extent or amount of the first portion 133 and / or the second portion 134 can be similarly modified.

[0102] For example, by increasing the number of courses using the second yarn 903 to form the first portion 133 and / or by decreasing the number of courses using the third yarn 905 to form the second portion 134, the color shifting properties provided by the knitted component 130 having this configuration can be changed so as to increase the number of viewing angles associated with the visual effect or color from the first portion 133 and / or decrease the number of viewing angles associated with the visual effect or color from the second portion 134. That is, a lens knit structure having a greater first portion than second portion will have more viewing angles associated with the visual effect caused by the first portion (as opposed to the second portion), assuming a greater extent of the second yarn forms the resulting lens knit structure.

[0103] In the example knit diagram 1200 described with respect to Figure 12 In the example knit diagram 1200 described with respect to Figure 13 An example knit diagram 1300 is illustrated for forming a lens knit structure 132 including an inlaid tensile element 724. As shown in Figure 13 The process is generally similar to the process shown in the knit diagram 1200 for forming a lens knit structure 132 of a hollow tubular rib structure as illustrated in Figure 12 The process is generally similar to the process shown in the knit diagram 1200 for forming a lens knit structure 132 of a hollow tubular rib structure as illustrated in

[0104] However, in the example knit diagram 1300, the inlaid tensile element 724 is formed in the center of the lens knit structure 132. Figure 13In the process of FIG. 12, after the course 1212 is formed on the back needle bed 702, the tensile element 724 is inlaid in a portion of the tubular rib structure forming the lens weave structure 132 at step 1302. The tensile element 724 can be inlaid at step 1302 using the associated inlay method described in U.S. Patent No. 8,522,577 to Combined Feeder and Huffa (incorporated by reference above).

[0105] After the tensile element 724 is inlaid in the lens weave structure 132 at step 1302, the process shown in the weave diagram 1300 proceeds in substantially similar fashion to the weave diagram 1200. That is, another set of looped courses 1214 can be formed extending between the back needle bed 702 and the front needle bed 701, the another set of looped courses 1214 interlooping with the previous courses on both the front needle bed 701 and the back needle bed 702. The third yarn 905 forming the second portion 134 of the lens weave structure 132 can be prepared to be transferred to the back needle bed 702 at step 1216 by using a down needle at the looped courses 1214 extending between the back needle bed 702 and the front needle bed 701 and repeating the process described above until the weave 130 is complete, associated with the additional courses formed using the back needle bed 702 from the first yarn 901 to form the other base portion 136. Using this configuration, the lens weave structure 132 including the inlaid tensile element 724 is formed with the tensile element 724 contained within a hollow unsecured region within the tubular rib structure extending along the length of the lens weave structure 132.

[0106] In other embodiments, the formation of the weave 130 can be similar, but necessitate the use of stitching of the needle beds, for example, Figure 12 and Figure 13 The weaving process shown in FIGS. 12 and 13 can be performed using opposing needle beds such that the base portion 136 can be formed using the front needle bed 701 and the remaining steps shown in FIGS. 12 and 13 can be performed in the same order using the needle beds opposite the illustrated needle beds. Other methods of using one or more needle beds of the weaving machine 700 to form the base portion 136 and the lens weave structure 132 (including the first portion 133 and the second portion 134) will be apparent to one of ordinary skill in the art based on the above description. Figure 12 and Figure 13 The weaving process shown in FIGS. 12 and 13 can be performed using opposing needle beds such that the base portion 136 can be formed using the front needle bed 701 and the remaining steps shown in FIGS. 12 and 13 can be performed in the same order using the needle beds opposite the illustrated needle beds. Other methods of using one or more needle beds of the weaving machine 700 to form the base portion 136 and the lens weave structure 132 (including the first portion 133 and the second portion 134) will be apparent to one of ordinary skill in the art based on the above description.

[0107] Figure 14 and Figure 15 FIG. 14 illustrates a representative view of a cross-section of the weave 130 incorporating the lens weave structure 132. Figure 14A representative view 1400 illustrating a portion of the woven component 130 incorporating the lens weave structure 132 having a hollow unsecured region 1410 is shown. As shown in this embodiment, each lens weave structure 132 includes a first portion 133 formed using the second yarn 903 and a second portion 134 formed using the third yarn 905. In the exemplary embodiment, at least one course of the first portion 133 formed using the second yarn 903 is interlooped with at least one course of the second portion 134 formed using the third yarn 905. Using this configuration, the first portion 133 and the second portion 134 are formed from a unitary woven construction. A base portion 136 of the woven component 130 is spaced between the lens weave structures 132 and separates each of the lens weave structures 132. The base portion 136 is formed from the first yarn 901 (as described above) and is also formed from a unitary woven construction with the first portion 133 and the second portion 134 on respective sides of the lens weave structure 132.

[0108] The configuration of the lens weave structure 132 including the first portion 133 formed by the second yarn 903 on one side of the tubular rib structure and the second portion 134 formed by the third yarn 905 on the opposite side of the tubular rib structure provides the woven component 130 with a color shifting property. As mentioned above, in one or more embodiments, the second yarn 903 and the third yarn 905 can be different types that provide different visual effects. For example, in this embodiment, the second yarn 903 can be associated with a first color and the third yarn 905 can be associated with a second color that is different from the first color. However, in other embodiments, the second yarn 903 and the third yarn 905 can be types having different characteristics that can induce a visual color shifting effect.

[0109] The color shifting property of the woven component 130 provided by the lens weave structure 132 will be described with reference to the representative view 1400. In this embodiment, when the woven component 130 is viewed from a first perspective 1402, the first portion 133 formed by the third yarn 905 is primarily and generally presented to the viewer. Thus, from the first perspective 1402, the first portion 133 of the lens weave structure 132 can provide the viewer with a primary overall visual effect of the woven component 130. In this case, the characteristics associated with the third yarn 905 forming the first portion 133 provide the visual effect, such as the color of the second yarn 903.

[0110] In contrast, when the woven component 130 is viewed from a second perspective 1404 that is different from the first perspective 1402, the viewer is presented with a different visual effect. In this embodiment, when the woven component 130 is viewed from the second perspective 1404, the second portion 134 formed by the third yarn 905 is primarily and substantially presented to the viewer. Thus, from the second perspective 1404, the second portion 134 of the lens weave structure 132 can provide the viewer with a primary overall visual appearance of the woven component 130. In this case, the characteristic associated with the third yarn 905 forming the second portion 134 provides the visual effect, such as a color of the third yarn 905 that is different from a color of the second yarn 903. As previously noted, in other embodiments, the different visual effect provided between the second yarn 903 and the third yarn 905 can include other characteristics, including but not limited to: yarn type, denier, texture, or other properties that produce a different visual effect.

[0111] Using this configuration of the lens weave structure 132 on the woven component 130, a color shifting property of the upper 120 and / or article 100 can be provided such that a viewer observes a change in the visual effect of the upper 120 and / or article 100 when the perspective changes, such as when the perspective changes between the first perspective 1402 and the second perspective 1404. Further, as noted above, in some embodiments, the base portion 136 can be formed using a first yarn 901 that is similar to or different from either or both of the second yarn 903 and the third yarn 905 to operate in concert with or contrast the first portion 133 and / or the second portion 134 of the lens weave structure 132 to further assist in providing the visual effect of the woven component 130.

[0112] Referring now to Figure 15 , a representative view 1501 is illustrated of a portion of a woven component 130 incorporating lens weave structures 132 having an unsecured region 1410 including a tensile resistance element 724. In this embodiment, each of the lens weave structures 132 includes an inlaid tensile resistance element 724 extending through the unsecured region 1410 within an interior of the tubular rib structure forming the lens weave structure 132. As shown in Figure 15 , each of the lens weave structures 132 includes an accompanying tensile resistance element 724. However, in other embodiments, the tensile resistance element 724 can be disposed in only selected lens weave structures 132 located in a particular region or area of the woven component 130. For example, as shown in Figure 1 , the tensile resistance element 724 can be included in the lens weave structures 132 located along an instep region 150 to provide a lace receiving member 154 forming a loop to receive a lace 152. In still other embodiments, the tensile resistance element 724 can be omitted.

[0113] The previous embodiments of the woven component 130 illustrate a lens weave 132 having two portions formed using different yarns to provide color shifting properties to the upper 120 and article 100. In other embodiments, a lens weave can be formed that includes an additional portion formed using another type of yarn that is different from both of the two yarns used to form the first and second portions of the lens weave. Figures 16 to 22 An example embodiment of an article of footwear 1600 including a lens weave having three portions formed using different yarns is illustrated.

[0114] For purposes of description Figures 16 to 22 An example coordinate system for the example embodiment of the article 1600 illustrated in Figure 19 is illustrated in FIG. 16, where a longitudinal direction 2 extends along the article 1600 between a forefoot region 10 and a heel region 14 of the article 1600, a lateral direction 4 extends along the article 1600 between a lateral side 16 and a medial side 18 of the article 1600, and a vertical direction 6 extends along the article 1600 between a sole structure 110 and a top of the article 1600.

[0115] In some embodiments, the article 1600 includes an upper 1620 that includes generally similar components to those associated with the upper 120 described above. For example, the upper 1620 can include a throat opening 140 surrounded by a collar 142, and can be connected along a seam 160 as described above. Similarly, the upper 1620 can include an exterior surface 121 and an interior surface 122 associated with an exterior and an interior of the article 1600, respectively. The upper 1620 can be connected or secured to the sole structure 110 to complete the article of footwear 1600.

[0116] In an example embodiment, the upper 1620 incorporates a woven component 1630 including a first lens weave 1632 having two portions formed from two different yarns in a generally similar manner to that described above for forming the lens weave 132, and generally similar to the lens weave 132 described above. In an example embodiment, the woven component 1630 further includes at least one region 1602 having a second lens weave 1638 having three portions formed from three different yarns. Further, in this embodiment, the woven component 1630 includes a base portion 1636 disposed between one or more of the first lens weave 1632 and / or the second lens weave 1638. In one embodiment, the base portion 1636 can be formed in a generally similar manner to that described above for forming the base portion 136, and is generally similar to the base portion 136 described above.

[0117] Referring to Figure 16 In this embodiment, the woven component 1630 includes a region 1602 having one or more second lens weave structures 1638, while the remainder of the woven component 1630 includes the first lens weave structure 1632. Although this embodiment illustrates a single region 1602 having the second lens weave structure 1638, it should be understood that additional or different regions can be provided on other regions or portions of the woven component 1630. Further, in some embodiments, the region 1602 can be selected to act as a marker, logo, pattern, or other visual effect that is different from the remainder of the woven component 1630.

[0118] In example embodiments, the first lens weave structure 1632 can provide the color shifting properties to the woven component 1630 by incorporating the type of yarn used to weave the first lens weave structure 1632. For example, in embodiments in which the lens weave structure 1632 is in the form of a tubular rib structure, different portions of the first lens weave structure 1632 can include different types of yarn along each side of the tubular rib structure. In one embodiment, a first portion 1633 of the first lens weave structure 1632 disposed on one side of the tubular rib structure can be woven using a first yarn, and a second portion 1634 of the first lens weave structure 1632 disposed on an opposite side of the tubular rib structure can be woven using a second yarn that is different from the first yarn. In some cases, the type of yarn can change color to provide the color shifting properties to the woven component 1630. In other cases, the type of yarn can change texture or denier to provide the color shifting properties to the woven component 1630.

[0119] In some embodiments, the woven component 1630 further includes a region 1602 having a second lens weave structure 1638. As with the first lens weave structure 1632, the second lens weave structure 1638 can similarly provide color-shifting properties to the woven component 1630 by incorporating the type(s) of yarn used to weave the lens weave structure 1638. For example, in embodiments in which the second lens weave structure 1638 is in the form of a tubular rib structure, different portions of the second lens weave structure 1638 can similarly include different types of yarn along each side of the tubular rib structure, including a first portion 1633 of the second lens weave structure 1638 disposed on one side of the tubular rib structure that is woven using a first yarn, and a second portion 1634 of the second lens weave structure 1638 disposed on an opposite side of the tubular rib structure that is woven using a second yarn that is different than the first yarn. In this embodiment, the second lens weave structure 1638 further includes an upper portion 1637 disposed on a top of the tubular rib structure that is formed using a third yarn that is different than both the first yarn and the second yarn used for each of the first portion 1633 and the second portion 1634. Using this configuration, the second lens weave structure 1638 can present a third visual effect to the woven component 1630 resulting from the upper portion 1637 that is different than the visual effects presented by the first portion 1633 and / or the second portion 1634 disposed along the sides of the second lens weave structure 1638 and the first lens weave structure 1632.

[0120] In one embodiment, the region 1602 having the second lens weave structure 1638 can be located approximately in a portion of the forefoot region 10 and / or the midfoot region 12, and offset toward the lateral side 16 of the article 1600. Using this configuration, the region 1602 can present a third visual effect to a viewer when viewing the article 1600 and the upper 1620 from a perspective that includes at least a portion of the lateral side 16, while the region 1602 does not present the third visual effect to the viewer when viewing the article 1600 and the upper 1620 from a perspective that is primarily along the medial side 18. For example, as shown in the medial side view illustrated in Figure 17 , the region 1602 is not visible from the medial side 18. However, as shown in the lateral side view illustrated in Figure 18 , the region 1602 is visible from the lateral side 16. Similarly, when viewing the article 1600 and the upper 1620 from a perspective that is primarily along the lateral side 18, the region 1602 does not present the third visual effect to the viewer. For example, as shown in the medial side view illustrated in Figure 19The area 1602 is also visible to a viewer when viewing the article 1600 and the upper 1620 in a top view or a front view. Using this configuration, the area 1602, which includes the second lens weave structure 1638, can be selectively provided on various portions of the knitted component 1630. However, in different embodiments, the area 1602 or additional areas can be located on different portions of the upper 1620 as desired to produce different color shifting properties on those portions of the upper 1620.

[0121] As mentioned above, the first lens weave structure 1632 can be formed in a generally similar manner as the lens weave structure 132 shown in particular in the knitting diagrams 1200 and 1300 described above and referenced with respect to Figure 12 and Figure 13 The knitting process used to knit the second lens weave structure 1638 can include many similar steps as the first lens weave structure 1632 and / or the lens weave structure 132. However, in contrast, a third yarn can be used to form the upper portion 1637 of the second lens weave structure 1638 so as to impart a third visual effect to the knitted component 1630. Figures 20 to 21 An exemplary knitting or loop diagram illustrating the order in which each portion of the knitted component 1630, including the base portion 1636, the first portion 1633, the second portion 1634, and the upper portion 1637, can be knitted with respect to the particular needle bed that can be used to form each portion is shown. However, it should be noted that Figure 20 and Figure 21 One exemplary configuration for a knitting process used to form the knitted component 1630 is shown. Other configurations can be readily obtained in accordance with the principles of the application described herein to form other lens weave structures to provide color shifting properties to an article.

[0122] In one embodiment of the third knitting diagram 2000 shown in Figure 20 the base portion 1636 can be formed using the back needle bed 702 from the first yarn 901, followed by the first portion 1633 of the second lens weave structure 1638 being formed from the second yarn 903, and the second portion 1634 of the second lens weave structure 1638 being formed using a combination of the back needle bed 702 and the front needle bed 701 from the third yarn 905, and another base portion 1636 can be formed using the back needle bed 702 from the first yarn 901. The following discussion describes Figures 20-21 the knitting process schematically illustrated in Figure 7 is shown schematically.

[0123] Referring again to Figure 20After the final course 2002 using the first yarn 901 to form the base portion 1636, a tuck course 2004 can be formed extending between the back needle bed 702 and the front needle bed 701. Next, one or more courses can be knitted on the front needle bed 701. For example, courses to form the first portion 1633 of the second lens knit structure 1638 can be formed in a similar manner as courses 2006 knitted on the front needle bed 701 using the second yarn 903. Next, after the final course 2008 using the second yarn 903 to knit the first portion 1633 on the front needle bed 701, courses to form the upper portion 1637 of the second lens knit structure 1638 can be formed in a similar manner as courses 2010 using the fourth yarn 907.

[0124] After the desired number of courses to form the upper portion 1637 are knitted using the fourth yarn 907, additional courses to form the second portion 1634 of the second lens knit structure 1638 can be formed in a similar manner as courses 2012 on the front needle bed 701 using the third yarn 905. After the desired number of courses to form the second portion 1634 are knitted on the front needle bed 701, the third yarn 905 can be used to knit courses 2014 using the back needle bed 702. For example, the courses 2014 can form the last courses of the closed tubular rib structure of the second portion 1634 of the second lens knit structure 1638 and form the hollow channel. After the courses 2014 complete the second lens knit structure 1638, another tuck course 2016 can be formed extending between the back needle bed 702 and the front needle bed 701, which tuck course 2016 interlaces with the previous courses on the front needle bed 701 and the back needle bed 702. By using the under needle at the tuck course 2016 extending between the back needle bed 702 and the front needle bed 701, the third yarn 905 to form the second portion 1634 of the second lens knit structure 1638 can be prepared to be transferred to the back needle bed 702 at step 2018 and repeat the process described above until the knit component 1630 is complete in association with forming additional courses of the base portion 1636 using the back needle bed 702 from the first yarn 901.

[0125] In various embodiments, different numbers of courses can be knitted on one or both of the front needle bed 701 and the back needle bed 702 in order to vary the shape and / or size of the tubular rib structure forming the second lens knit structure 1638, as described above with respect to the lens knit structure 132.

[0126] In various embodiments, the lens knit structure 132 can be formed in a similar manner as the lens knit structure 1638 described above with respect to the lens knit structure 132. Figure 20In the exemplary braiding diagram 2000 described, the second lens braided structure 1638 is formed as a hollow tubular rib structure. In other embodiments, the tensile resistant elements can be inlaid within the unsecured central region of one or more second lens braided structures 1638 forming a tubular rib structure in a similar manner as the first lens braided structure 1632 and / or the lens braided structure 132. Figure 21 An exemplary braiding diagram 2100 is illustrated for forming a second lens braided structure 1638 including inlaid tensile resistant elements 724. As Figure 21 shown in FIG. 20, the process is generally similar to the process illustrated in FIG. 20 for forming the second lens braided structure 1638 as a hollow tubular rib structure. Figure 20

[0127] However, in the process of FIG. 21, after the course 2014 is formed on the back needle bed 702, the tensile resistant elements 724 are inlaid within a portion of the tubular rib structure forming the second lens braided structure 1638 at an inlay step 2102. The tensile resistant elements 724 can be inlaid at step 2102 using the associated inlay method described in U.S. Patent No. 8,522,577 to Combination Feeder and Huffa (incorporated by reference above). Figure 21

[0128] After the tensile resistant elements 724 are inlaid within the second lens braided structure 1638 at step 2102, the process illustrated in braiding diagram 2100 proceeds in a generally similar manner as the braiding diagram 2000. That is, another set of looped courses 2016 can be formed extending between the back needle bed 702 and the front needle bed 701, the another set of looped courses 2016 being looped with the previous courses on the front needle bed 701 and the back needle bed 702. By using the under needles at the looped courses 2016 extending between the back needle bed 702 and the front needle bed 701, the third yarns 905 forming the second portion 1634 of the second lens braided structure 1638 can be prepared to be associated with additional courses using the back needle bed 702 to form another base portion 1636 from the first yarns 901 by transferring the braided component 1630 to the back needle bed 702 at step 2018 and repeating the process described above until the braided component 1630 is complete. Using this configuration, the second lens braided structure 1638 including the inlaid tensile resistant elements 724 is formed with the tensile resistant elements 724 contained within a hollow unsecured region within the tubular rib structure extending along the length of the second lens braided structure 1638.

[0129] Figure 22 ​​A representative view 2200 of a cross-section of a portion of the woven component 1630 incorporating the second lens weave 1638 is illustrated. For example, the view 2200 can be a portion of the woven component associated with the area 1602. In this embodiment, the portion of the woven component 1630 incorporates the second lens weave 1638 having a hollow unsecured area 2210. It should be appreciated that the second lens weave 1638 including the inlaid tensile element 724 can have substantially similar structure as the inlaid tensile element 724 located in the hollow unsecured area 2210. As shown in this embodiment, each second lens weave 1638 includes a first portion 1633 formed using the second yarn 903 and a second portion 1634 formed using the third yarn 905. Further, in contrast to the first lens weave 1632, the second lens weave 1638 also includes an upper portion 1637 formed using the fourth yarn 907.

[0130] In example embodiments, the upper portion 1637 is located at the top of the tubular rib structure forming the second lens weave 1638. In some embodiments, the upper portion 1637 formed using the fourth yarn 907 can be disposed between the first portion 1633 and the second portion 1634. That is, at least one course of the first portion 1633 formed using the second yarn 903 is interlooped with at least one course of the upper portion 1637 formed using the fourth yarn 907, and at least one course of the second portion 1634 formed using the third yarn 905 is also interlooped with at least one course of the upper portion 1637 formed using the fourth yarn 907. Using this configuration, each of the first portion 1633, the upper portion 1637, and the second portion 1634 are formed from a unitary woven construction. The base portion 1636 of the woven component 1630 is spaced between the second lens weaves 1638 and separates each of the second lens weaves 1638. The base portion 1636 is formed from the first yarn 901 (as described above) and is also formed from a unitary woven construction with the first portion 1633 and the second portion 1634 on respective sides of the second lens weave 1638.

[0131] The configuration of the second lens weave structure 1638, including the first portion 1633 formed by the second yarn 903 on one side of the tubular rib structure and the second portion 1634 formed by the third yarn 905 on the opposite side of the tubular rib structure, provides the woven component 1630 with a color shifting property. Additionally, the upper portion 1637 of the second lens weave structure 1638 formed by the fourth yarn 907 on the top of the tubular rib structure can provide the woven component 1630 with an additional visual effect. As mentioned above, in various embodiments, the second yarn 903 and the third yarn 905 can be different types that provide different visual effects. For example, in this embodiment, the second yarn 903 can be associated with a first color and the third yarn 905 can be associated with a second color that is different than the first color. However, in other embodiments, the second yarn 903 and the third yarn 905 can be types that have different characteristics that can cause a visual color shifting effect. Additionally, the fourth yarn 907 can be a different type than either or both of the second yarn 903 and the third yarn 905.

[0132] The color shifting property of the woven component 1630 provided by the second lens weave structure 1638 will be described with reference to a representative view 2200. In this embodiment, when the woven component 1630 is viewed from a first perspective 2202, the first portion 1633 formed by the second yarn 903 is primarily and generally presented to the viewer.
