- FIG. 1 -4C An article of footwear 100 is depicted in Figures 1 -4C as including a sole structure 1 10 and an upper 120.
- footwear 100 is illustrated as having a general configuration suitable for running, concepts associated with footwear 100 may also be applied to a variety of other athletic footwear types, including baseball shoes, basketball shoes, cycling shoes, football shoes, tennis shoes, soccer shoes, training shoes, walking shoes, and hiking boots, for example.
- the concepts may also be applied to footwear types that are generally considered to be non-athletic, including dress shoes, loafers, sandals, and work boots. Accordingly, the concepts disclosed with respect to footwear 100 apply to a wide variety of footwear types.
- footwear 100 may be divided into three general regions: a forefoot region 101 , a midfoot region 102, and a heel region 103.
- Forefoot region 101 generally includes portions of footwear 100 corresponding with the toes and the joints connecting the metatarsals with the phalanges.
- Midfoot region 102 generally includes portions of footwear 100 corresponding with an arch area of the foot.
- Heel region 103 generally corresponds with rear portions of the foot, including the calcaneus bone.
- Footwear 100 also includes a lateral side 104 and a medial side 105, which extend through each of regions 101 -103 and correspond with opposite sides of footwear 100. More particularly, lateral side 104 corresponds with an outside area of the foot (i.e. the surface that faces away from the other foot), and medial side 105 corresponds with an inside area of the foot (i.e., the surface that faces toward the other foot). Regions 101 -103 and sides 104-105 are not intended to demarcate precise areas of footwear 100. Rather, regions 101 -103 and sides 104-105 are intended to represent general areas of footwear 100 to aid in the following discussion. In addition to footwear 100, regions 101 -103 and sides 104-105 may also be applied to sole structure 1 10, upper 120, and individual elements thereof.
- Sole structure 1 10 is secured to upper 120 and extends between the foot and the ground when footwear 100 is worn.
- the primary elements of sole structure 1 10 are a midsole 1 1 1 , an outsole 1 12, and a sockliner 1 13.
- Midsole 1 1 1 is secured to a lower surface of upper 120 and may be formed from 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.
- a compressible polymer foam element e.g., a polyurethane or ethylvinylacetate foam
- midsole 1 1 1 may incorporate plates, moderators, fluid-filled chambers, lasting elements, or motion control members that further attenuate forces, enhance stability, or influence the motions of the foot, or midsole 21 may be primarily formed from a fluid-filled chamber.
- Outsole 1 12 is secured to a lower surface of midsole 1 1 1 and may be formed from a wear-resistant rubber material that is textured to impart traction.
- Sockliner 1 13 is located within upper 120 and is positioned to extend under a lower surface of the foot to enhance the comfort of footwear 100.
- Upper 120 defines a void within footwear 100 for receiving and securing a foot relative to sole structure 1 10.
- the void is shaped to
- Access to the void is provided by an ankle opening 121 located in at least heel region 103.
- a lace 122 extends through various lace apertures 123 in upper 120 and permits the wearer to modify dimensions of upper 120 to
- upper 120 includes a tongue 124 that extends under lace 122 and lace apertures 123 to enhance the comfort of footwear 100.
- upper 120 may include additional elements, such as (a) a heel counter in heel region 103 that enhances stability, (b) a toe guard in forefoot region 101 that is formed of a wear-resistant material, and (c) logos, trademarks, and placards with care instructions and material information.
- Many conventional footwear uppers are formed from multiple material elements (e.g., textiles, polymer foam, polymer sheets, leather, synthetic leather) that are joined through stitching or bonding, for example.
- a majority of upper 120 is formed from a knitted component 130, which extends through each of regions 101 -103, along both lateral side 104 and medial side 105, over forefoot region 101 , and around heel region 103.
- knitted component 130 forms portions of both an exterior surface and an opposite interior surface of upper 120.
- knitted component 130 defines at least a portion of the void within upper 120.
- knitted component 130 may also extend under the foot. Referring to Figures 4A-4C, however, a strobel sock 125 is secured to knitted component 130 and an upper surface of midsole 1 1 1 , thereby forming a portion of upper 120 that extends under sockliner 1 13.
- Knitted component 130 is depicted separate from a remainder of footwear 100 in Figures 5 and 6.
- Knitted component 130 is formed of unitary knit construction.
- a knitted component e.g., knitted component 130
- a knitted component is defined as being formed of "unitary knit construction" when formed as a one-piece element through a knitting process. That is, the knitting process substantially forms the various features and structures of knitted component 130 without the need for significant additional manufacturing steps or processes.
- portions of knitted component 130 may be joined to each other (e.g., edges of knitted component 130 being joined together) following the knitting process, knitted component 130 remains formed of unitary knit construction because it is formed as a one-piece knit element.
- knitted component 130 remains formed of unitary knit construction when other elements (e.g., lace 122, tongue 124, logos, trademarks, placards with care instructions and material information) are added following the knitting process.
- the primary elements of knitted component 130 are a knit element 131 and an inlaid strand 132.
- Knit element 131 is formed from at least one yarn that is manipulated (e.g., with a knitting machine) to form a plurality of intermeshed loops that define a variety of courses and wales. That is, knit element 131 has the structure of a knit textile.
- Inlaid strand 132 extends through knit element 131 and passes between the various loops within knit element 131 . Although inlaid strand 132 generally extends along courses within knit element 131 , inlaid strand 132 may also extend along wales within knit element 131 . Advantages of inlaid strand 132 include providing support, stability, and structure.
- Knit element 131 has a generally U-shaped configuration that is outlined by a perimeter edge 133, a pair of heel edges 134, and an inner edge 135. When incorporated into footwear 100, perimeter edge 133 lays against the upper surface of midsole 1 1 1 and is joined to strobel sock 125.
- Heel edges 134 are joined to each other and extend vertically in heel region 103.
- a material element may cover a seam between heel edges 134 to reinforce the seam and enhance the aesthetic appeal of footwear 100.
- Inner edge 135 forms ankle opening 121 and extends forward to an area where lace 122, lace apertures 123, and tongue 124 are located.
- knit element 131 has a first surface 136 and an opposite second surface 137. First surface 136 forms a portion of the exterior surface of upper 120, whereas second surface 137 forms a portion of the interior surface of upper 120, thereby defining at least a portion of the void within upper 120.
- Inlaid strand 132 extends through knit element 131 and passes between the various loops within knit element 131 . More particularly, inlaid strand 132 is located within the knit structure of knit element 131 , which may have the configuration of a single textile layer in the area of inlaid strand 132, and between surfaces 136 and 137, as depicted in Figures 7A-7D. When knitted component 130 is incorporated into footwear 100, therefore, inlaid strand 132 is located between the exterior surface and the interior surface of upper 120. In some configurations, portions of inlaid strand 132 may be visible or exposed on one or both of surfaces 136 and 137.
- inlaid strand 132 may lay against one of surfaces 136 and 137, or knit element 131 may form indentations or apertures through which inlaid strand passes.
- An advantage of having inlaid strand 132 located between surfaces 136 and 137 is that knit element 131 protects inlaid strand 132 from abrasion and snagging.
- inlaid strand 132 repeatedly extends from perimeter edge 133 toward inner edge 135 and adjacent to a side of one lace aperture 123, at least partially around the lace aperture 123 to an opposite side, and back to perimeter edge 133.
- knit element 131 extends from a throat area of upper 120 (i.e., where lace 122, lace apertures 123, and tongue 124 are located) to a lower area of upper 120 (i.e., where knit element 131 joins with sole structure 1 10.
- inlaid strand 132 also extends from the throat area to the lower area. More particularly, inlaid strand repeatedly passes through knit element 131 from the throat area to the lower area.
- knit element 131 may be formed in a variety of ways, courses of the knit structure generally extend in the same direction as inlaid strands 132. That is, courses may extend in the direction extending between the throat area and the lower area. As such, a majority of inlaid strand 132 extends along the courses within knit element 131 . In areas adjacent to lace apertures 123, however, inlaid strand 132 may also extend along wales within knit element 131 . More particularly, sections of inlaid strand 132 that are parallel to inner edge 135 may extend along the wales.
- inlaid strand 132 passes back and forth through knit element 131 .
- inlaid strand 132 also repeatedly exits knit element 131 at perimeter edge 133 and then re-enters knit element 131 at another location of perimeter edge 133, thereby forming loops along perimeter edge 133.
- An advantage to this configuration is that each section of inlaid strand 132 that extends between the throat area and the lower area may be independently tensioned, loosened, or otherwise adjusted during the manufacturing process of footwear 100. That is, prior to securing sole structure 1 10 to upper 120, sections of inlaid strand 132 may be independently adjusted to the proper tension.
- inlaid strand 132 may exhibit greater stretch-resistance. That is, inlaid strand 132 may stretch less than knit element 131 . Given that numerous sections of inlaid strand 132 extend from the throat area of upper 120 to the lower area of upper 120, inlaid strand 132 imparts stretch-resistance to the portion of upper 120 between the throat area and the lower area. Moreover, placing tension upon lace 122 may impart tension to inlaid strand 132, thereby inducing the portion of upper 120 between the throat area and the lower area to lay against the foot. As such, inlaid strand 132 operates in connection with lace 122 to enhance the fit of footwear 100.
- Knit element 131 may incorporate various types of yarn that impart different properties to separate areas of upper 120. That is, one area of knit element 131 may be formed from a first type of yarn that imparts a first set of properties, and another area of knit element 131 may be formed from a second type of yarn that imparts a second set of properties. In this
- properties may vary throughout upper 120 by selecting specific yarns for different areas of knit element 131 .
- the properties that a particular type of yarn will impart to an area of knit element 131 partially depend upon the materials that form the various filaments and fibers within the yarn.
- Cotton for example, provides a soft hand, natural aesthetics, and biodegradability.
- Elastane and stretch polyester each provide substantial stretch and recovery, with stretch polyester also providing recyclability.
- Rayon provides high luster and moisture absorption.
- Wool also provides high moisture absorption, in addition to insulating properties and biodegradability.
- Nylon is a durable and abrasion-resistant material with relatively high strength.
- Polyester is a hydrophobic material that also provides relatively high durability.
- other aspects of the yarns selected for knit element 131 may affect the properties of upper 120.
- a yarn forming knit element 131 may be a monofilament yarn or a multifilament yarn.
- the yarn may also include separate filaments that are each formed of different materials.
- the yarn may include filaments that are each formed of two or more different materials, such as a bicomponent yarn with filaments having a sheath-core configuration or two halves formed of different materials. Different degrees of twist and crimping, as well as different deniers, may also affect the properties of upper 120. Accordingly, both the materials forming the yarn and other aspects of the yarn may be selected to impart a variety of properties to separate areas of upper 120.
- inlaid strand 132 may also vary significantly.
- inlaid strand 132 may have the configurations of a filament (e.g., a monofilament), thread, rope, webbing, cable, or chain, for example.
- the thickness of inlaid strand 132 may be greater.
- inlaid strand 132 may have a significantly greater thickness than the yarns of knit element 131 .
- the cross-sectional shape of inlaid strand 132 may be round, triangular, square, rectangular, elliptical, or irregular shapes may also be utilized.
- the materials forming inlaid strand 132 may include any of the materials for the yarn within knit element 131 , such as cotton, elastane, polyester, rayon, wool, and nylon. As noted above, inlaid strand 132 may exhibit greater stretch-resistance than knit element 131 . As such, suitable materials for inlaid strands 132 may include a variety of engineering filaments that are utilized for high tensile strength applications, including glass, aramids (e.g., para-aramid and meta- aramid), ultra-high molecular weight polyethylene, and liquid crystal polymer. As another example, a braided polyester thread may also be utilized as inlaid strand 132.
- knit element 131 includes a yarn 138 that forms a plurality of intermeshed loops defining multiple horizontal courses and vertical wales.
- Inlaid strand 132 extends along one of the courses and alternates between being located (a) behind loops formed from yarn 138 and (b) in front of loops formed from yarn 138. In effect, inlaid strand 132 weaves through the structure formed by knit element 131 .
- yarn 138 forms each of the courses in this configuration, additional yarns may form one or more of the courses or may form a portion of one or more of the courses.
- knit element 131 includes yarn 138 and another yarn 139.
- Yarns 138 and 139 are plated and cooperatively form a plurality of intermeshed loops defining multiple horizontal courses and vertical wales. That is, yarns 138 and 139 run parallel to each other.
- inlaid strand 132 extends along one of the courses and alternates between being located (a) behind loops formed from yarns 138 and 139 and (b) in front of loops formed from yarns 138 and 139.
- yarns 138 and 139 may be present in this area of knitted component 130.
- yarns 138 and 139 may have different colors, with the color of yarn 138 being primarily present on a face of the various stitches in knit element 131 and the color of yarn 139 being primarily present on a reverse of the various stitches in knit element 131 .
- yarn 139 may be formed from a yarn that is softer and more comfortable against the foot than yarn 138, with yarn 138 being primarily present on first surface 136 and yarn 139 being primarily present on second surface 137.
- yarn 138 may be formed from at least one of a thermoset polymer material and natural fibers (e.g., cotton, wool, silk), whereas yarn 139 may be formed from a thermoplastic polymer material.
- a thermoplastic polymer material melts when heated and returns to a solid state when cooled. More particularly, the thermoplastic polymer material transitions from a solid state to a softened or liquid state when subjected to sufficient heat, and then the thermoplastic polymer material transitions from the softened or liquid state to the solid state when sufficiently cooled.
- thermoplastic polymer materials are often used to join two objects or elements together.
- yarn 139 may be utilized to join (a) one portion of yarn 138 to another portion of yarn 138, (b) yarn 138 and inlaid strand 132 to each other, or (c) another element (e.g., logos, trademarks, and placards with care instructions and material information) to knitted component 130, for example.
- yarn 139 may be considered a fusible yarn given that it may be used to fuse or otherwise join portions of knitted component 130 to each other.
- yarn 138 may be considered a non-fusible yarn given that it is not formed from materials that are generally capable of fusing or otherwise joining portions of knitted component 130 to each other.
- yarn 138 may be a non-fusible yarn
- yarn 139 may be a fusible yarn.
- yarn 138 i.e., the non-fusible yarn
- yarn 139 i.e., the fusible yarn
- the use of plated yarns may impart advantages to knitted component 130. When yarn 139 is heated and fused to yarn 138 and inlaid strand 132, this process may have the effect of stiffening or rigidifying the structure of knitted component 130.
- joining (a) one portion of yarn 138 to another portion of yarn 138 or (b) yarn 138 and inlaid strand 132 to each other has the effect of securing or locking the relative positions of yarn 138 and inlaid strand 132, thereby imparting stretch-resistance and stiffness. That is, portions of yarn 138 may not slide relative to each other when fused with yarn 139, thereby preventing warping or permanent stretching of knit element 131 due to relative movement of the knit structure. Another benefit relates to limiting unraveling if a portion of knitted component 130 becomes damaged or one of yarns 138 is severed.
- inlaid strand 132 may not slide relative to knit element 131 , thereby preventing portions of inlaid strand 132 from pulling outward from knit element 131 . Accordingly, areas of knitted component 130 may benefit from the use of both fusible and non-fusible yarns within knit element 131 .
- knitted component 130 relates to a padded area adjacent to ankle opening 121 and extending at least partially around ankle opening 121 .
- the padded area is formed by two overlapping and at least partially coextensive knitted layers 140, which may be formed of unitary knit construction, and a plurality of floating yarns 141 extending between knitted layers 140.
- knitted layers 140 effectively form a tube or tubular structure, and floating yarns 141 may be located or inlaid between knitted layers 140 to pass through the tubular structure. That is, floating yarns 141 extend between knitted layers 140, are generally parallel to surfaces of knitted layers 140, and also pass through and fill an interior volume between knitted layers 140.
- knitted layers 140 may be at least partially formed from a stretch yarn.
- An advantage of this configuration is that knitted layers will effectively compress floating yarns 141 and provide an elastic aspect to the padded area adjacent to ankle opening 121 . That is, the stretch yarn within knitted layers 140 may be placed in tension during the knitting process that forms knitted component 130, thereby inducing knitted layers 140 to compress floating yarns 141 .
- the degree of stretch in the stretch yarn may vary significantly, the stretch yarn may stretch at least one-hundred percent in many configurations of knitted component 130.
- conventional articles of footwear incorporate polymer foam elements or other compressible materials into areas adjacent to an ankle opening.
- portions of knitted component 130 formed of unitary knit construction with a remainder of knitted component 130 may form the padded area adjacent to ankle opening 121 .
- similar padded areas may be located in other areas of knitted component 130.
- similar padded areas may be located as an area corresponding with joints between the metatarsals and proximal phalanges to impart padding to the joints.
- a terry loop structure may also be utilized to impart some degree of padding to areas of upper 120.
- knit component 130 imparts a variety of features to upper 120. Moreover, knit component 130 provides a variety of advantages over some conventional upper configurations.
- conventional footwear uppers are formed from multiple material elements (e.g., textiles, polymer foam, polymer sheets, leather, synthetic leather) that are joined through stitching or bonding, for example.
- material elements e.g., textiles, polymer foam, polymer sheets, leather, synthetic leather
- the time and expense associated with transporting, stocking, cutting, and joining the material elements may also increase. Waste material from cutting and stitching processes also accumulates to a greater degree as the number and type of material elements incorporated into the upper increases.
- uppers with a greater number of material elements may be more difficult to recycle than uppers formed from fewer types and numbers of material elements.
- waste may be decreased while increasing the manufacturing efficiency and recyclability of the upper.
- knitted component 130 forms a substantial portion of upper 120, while increasing manufacturing efficiency, decreasing waste, and simplifying recyclability.
- a knitted component 150 is depicted in Figures 9 and 10 and may be utilized in place of knitted component 130 in footwear 100.
- the primary elements of knitted component 150 are a knit element 151 and an inlaid strand 152.
- Knit element 151 is formed from at least one yarn that is manipulated (e.g., with a knitting machine) to form a plurality of intermeshed loops that define a variety of courses and wales. That is, knit element 151 has the structure of a knit textile.
- Inlaid strand 152 extends through knit element 151 and passes between the various loops within knit element 151 .
- inlaid strand 152 generally extends along courses within knit element 151
- inlaid strand 152 may also extend along wales within knit element 151 .
- inlaid strand 152 imparts stretch-resistance and, when incorporated into footwear 100, operates in connection with lace 122 to enhance the fit of footwear 100.
- Knit element 151 has a generally U-shaped configuration that is outlined by a perimeter edge 153, a pair of heel edges 154, and an inner edge 155.
- knit element 151 has a first surface 156 and an opposite second surface 157.
- First surface 156 may form a portion of the exterior surface of upper 120
- second surface 157 may form a portion of the interior surface of upper 120, thereby defining at least a portion of the void within upper 120.
- knit element 151 may have the configuration of a single textile layer in the area of inlaid strand 152. That is, knit element 151 may be a single textile layer between surfaces 156 and 157.
- knit element 151 defines a plurality of lace apertures 158.
- inlaid strand 152 Similar to inlaid strand 132, inlaid strand 152 repeatedly extends from perimeter edge 153 toward inner edge 155, at least partially around one of lace apertures 158, and back to perimeter edge 153. In contrast with inlaid strand 132, however, some portions of inlaid strand 152 angle rearwards and extend to heel edges 154. More particularly, the portions of inlaid strand 152 associated with the most rearward lace apertures 158 extend from one of heel edges 154 toward inner edge 155, at least partially around one of the most rearward lace apertures 158, and back to one of heel edges 154.
- inlaid strand 152 do not extend around one of lace apertures 158. More particularly, some sections of inlaid strand 152 extend toward inner edge 155, turn in areas adjacent to one of lace apertures 158, and extend back toward perimeter edge 153 or one of heel edges 154.
- knit element 151 may be formed in a variety of ways, courses of the knit structure generally extend in the same direction as inlaid strands 152. In areas adjacent to lace apertures 158, however, inlaid strand 152 may also extend along wales within knit element 151 . More particularly, sections of inlaid strand 152 that are parallel to inner edge 155 may extend along wales.
- inlaid strand 152 may exhibit greater stretch-resistance. That is, inlaid strand 152 may stretch less than knit element 151 . Given that numerous sections of inlaid strand 152 extend through knit element 151 , inlaid strand 152 may impart stretch- resistance to portions of upper 120 between the throat area and the lower area. Moreover, placing tension upon lace 122 may impart tension to inlaid strand 152, thereby inducing the portions of upper 120 between the throat area and the lower area to lay against the foot. Additionally, given that numerous sections of inlaid strand 152 extend toward heel edges 154, inlaid strand 152 may impart stretch-resistance to portions of upper 120 in heel region 103.
- Knit element 151 may incorporate any of the various types of yarn discussed above for knit element 131 .
- Inlaid strand 152 may also be formed from any of the configurations and materials discussed above for inlaid strand 132. Additionally, the various knit configurations discussed relative to Figures 8A and 8B may also be utilized in knitted component 150.
- knit element 151 may have areas formed from a single yarn, two plated yarns, or a fusible yarn and a non-fusible yarn, with the fusible yarn joining (a) one portion of the non-fusible yarn to another portion of the non- fusible yarn or (b) the non-fusible yarn and inlaid strand 152 to each other.
- knit element 131 A majority of knit element 131 is depicted as being formed from a relatively untextured textile and a common or single knit structure (e.g., a tubular knit structure).
- knit element 151 incorporates various knit structures that impart specific properties and advantages to different areas of knitted component 150.
- knitted component 150 may impart a range of properties to different areas of upper 120.
- Figure 1 1 a schematic view of knitted component 150 shows various zones 160-169 having different knit structures, each of which will now be discussed in detail. For purposes of reference, each of regions 101 -103 and sides 104 and 105 are shown in Figure 1 1 to provide a reference for the locations of knit zones 160-169 when knitted component 150 is incorporated into footwear 100.
- a tubular knit zone 160 extends along a majority of perimeter edge 153 and through each of regions 101 -103 on both of sides 104 and 105. Tubular knit zone 160 also extends inward from each of sides 104 and 105 in an area approximately located at an interface of regions 101 and 102 to form a forward portion of inner edge 155. Tubular knit zone 160 forms a relatively untextured knit configuration. Referring to Figure 12A, a cross-section through an area of tubular knit zone 160 is depicted, and surfaces 156 and 157 are substantially parallel to each other. Tubular knit zone 160 imparts various advantages to footwear 100.
- tubular knit zone 160 has greater durability and wear resistance than some other knit structures, especially when the yarn in tubular knit zone 160 is plated with a fusible yarn.
- the relatively untextured aspect of tubular knit zone 160 simplifies the process of joining strobel sock 125 to perimeter edge 153. That is, the portion of tubular knit zone 160 located along perimeter edge 153 facilitates the lasting process of footwear 100.
- Figure 13A depicts a loop diagram of the manner in which tubular knit zone 160 is formed with a knitting process.
- Two stretch knit zones 161 extend inward from perimeter edge 153 and are located to correspond with a location of joints between metatarsals and proximal phalanges of the foot. That is, stretch zones extend inward from perimeter edge in the area approximately located at the interface regions 101 and 102.
- the knit configuration in stretch knit zones 161 may be a tubular knit structure.
- stretch knit zones 161 are formed from a stretch yarn that imparts stretch and recovery properties to knitted component 150. Although the degree of stretch in the stretch yarn may vary significantly, the stretch yarn may stretch at least one-hundred percent in many configurations of knitted component 150.
- a tubular and interlock tuck knit zone 162 extends along a portion of inner edge 155 in at least midfoot region 102.
- Tubular and interlock tuck knit zone 162 also forms a relatively untextured knit configuration, but has greater thickness than tubular knit zone 160.
- tubular and interlock tuck knit zone 162 is similar to Figure 12A, in which surfaces 156 and 157 are substantially parallel to each other.
- Tubular and interlock tuck knit zone 162 imparts various advantages to footwear 100.
- tubular and interlock tuck knit zone 162 has greater stretch resistance than some other knit structures, which is beneficial when lace 122 places tubular and interlock tuck knit zone 162 and inlaid strands 152 in tension.
- Figure 13B depicts a loop diagram of the manner in which tubular and interlock tuck knit zone 162 is formed with a knitting process.
- a 1 x1 mesh knit zone 163 is located in forefoot region 101 and spaced inward from perimeter edge 153.
- 1 x1 mesh knit zone has a C-shaped configuration and forms a plurality of apertures that extend through knit element 151 and from first surface 156 to second surface 157, as depicted in Figure 12B.
- the apertures enhance the permeability of knitted component 150, which allows air to enter upper 120 and moisture to escape from upper 120.
- Figure 13C depicts a loop diagram of the manner in which 1 x1 mesh knit zone 163 is formed with a knitting process.
- a 2x2 mesh knit zone 164 extends adjacent to 1 x1 mesh knit zone 163. In comparison with 1 x1 mesh knit zone 163, 2x2 mesh knit zone 164 forms larger apertures, which may further enhance the permeability of knitted component 150.
- Figure 13D depicts a loop diagram of the manner in which 2x2 mesh knit zone 164 is formed with a knitting process.
- a 3x2 mesh knit zone 165 is located within 2x2 mesh knit zone 164, and another 3x2 mesh knit zone 165 is located adjacent to one of stretch zones 161 .
- 3x2 mesh knit zone 165 forms even larger apertures, which may further enhance the permeability of knitted component 150.
- Figure 13E depicts a loop diagram of the manner in which 3x2 mesh knit zone 165 is formed with a knitting process.
- a 1 x1 mock mesh knit zone 166 is located in forefoot region 101 and extends around 1 x1 mesh knit zone 163. In contrast with mesh knit zones 163-165, which form apertures through knit element 151 , 1 x1 mock mesh knit zone 166 forms indentations in first surface 156, as depicted in Figure 12C. In addition to enhancing the aesthetics of footwear 100, 1 x1 mock mesh knit zone 166 may enhance flexibility and decrease the overall mass of knitted component 150. For purposes of reference, Figure 13F depicts a loop diagram of the manner in which 1 x1 mock mesh knit zone 166 is formed with a knitting process.
- Two 2x2 mock mesh knit zones 167 are located in heel region 103 and adjacent to heel edges 154. In comparison with 1 x1 mock mesh knit zone 166, 2x2 mock mesh knit zones 167 forms larger indentations in first surface 156. In areas where inlaid strands 152 extend through indentations in 2x2 mock mesh knit zones 167, as depicted in Figure 12D, inlaid strands 152 may be visible and exposed in a lower area of the indentations.
- Figure 13G depicts a loop diagram of the manner in which 2x2 mock mesh knit zones 167 are formed with a knitting process.
- Two 2x2 hybrid knit zones 168 are located in midfoot region 102 and forward of 2x2 mock mesh knit zones 167.
- 2x2 hybrid knit zones 168 share characteristics of 2x2 mesh knit zone 164 and 2x2 mock mesh knit zones 167. More particularly, 2x2 hybrid knit zones 168 form apertures having the size and configuration of 2x2 mesh knit zone 164, and 2x2 hybrid knit zones 168 form indentations having the size and configuration of 2x2 mock mesh knit zones 167.
- inlaid strands 152 extend through indentations in 2x2 hybrid knit zones 168, as depicted in Figure 12E, inlaid strands 152 are visible and exposed.
- Figure 13H depicts a loop diagram of the manner in which 2x2 hybrid knit zones 168 are formed with a knitting process.
- Knitted component 150 also includes two padded zones 169 having the general configuration of the padded area adjacent to ankle opening 121 and extending at least partially around ankle opening 121 , which was discussed above for knitted component 130.
- padded zones 169 are formed by two overlapping and at least partially coextensive knitted layers, which may be formed of unitary knit construction, and a plurality of floating yarns extending between the knitted layers.
- a comparison between Figures 9 and 10 reveals that a majority of the texturing in knit element 151 is located on first surface 156, rather than second surface 157. That is, the indentations formed by mock mesh knit zones 166 and 167, as well as the indentations in 2x2 hybrid knit zones 168, are formed in first surface 156.
- This configuration has an advantage of enhancing the comfort of footwear 100. More particularly, this configuration places the relatively untextured configuration of second surface 157 against the foot.
- a further comparison between Figures 9 and 10 reveals that portions of inlaid strand 152 are exposed on first surface 156, but not on second surface 157. This configuration also has an advantage of enhancing the comfort of footwear 100. More particularly, by spacing inlaid strand 152 from the foot by a portion of knit element 151 , inlaid strands 152 will not contact the foot.
- knitted component 130 concepts associated with each of these configurations may also be utilized with knitted component 150.
- inlaid strands 132 are absent from knitted component 130. Although inlaid strands 132 impart stretch-resistance to areas of knitted component 130, some configurations may not require the stretch-resistance from inlaid strands 132. Moreover, some configurations may benefit from greater stretch in upper 120.
- knit element 131 includes two flaps 142 that are formed of unitary knit construction with a remainder of knit element 131 and extend along the length of knitted component 130 at perimeter edge 133.
- flaps 142 When incorporated into footwear 100, flaps 142 may replace strobel sock 125. That is, flaps 142 may cooperatively form a portion of upper 120 that extends under sockliner 1 13 and is secured to the upper surface of midsole 1 1 1 .
- knitted component 130 has a configuration that is limited to midfoot region 102.
- other material elements e.g., textiles, polymer foam, polymer sheets, leather, synthetic leather
- stitching or bonding for example, to form upper 120.
- each of knit components 130 and 150 may have various configurations that impart features and advantages to upper 120. More particularly, knit elements 131 and 151 may incorporate various knit structures and yarn types that impart specific properties to different areas of upper 120, and inlaid strands 132 and 152 may extend through the knit structures to impart stretch-resistance to areas of upper 120 and operate in connection with lace 122 to enhance the fit of footwear 100.
- Knitting machine 200 has a configuration of a V-bed flat knitting machine for purposes of example, but either of knitted components 130 and 150 or aspects of knitted components 130 and 150 may be produced on other types of knitting machines.
- Knitting machine 200 includes two needle beds 201 that are angled with respect to each other, thereby forming a V-bed.
- Each of needle beds 201 include a plurality of individual needles 202 that lay on a common plane. That is, needles 202 from one needle bed 201 lay on a first plane, and needles 202 from the other needle bed 201 lay on a second plane.
- the first plane and the second plane i.e., the two needle beds 201
- needles 202 each have a first position where they are retracted and a second position where they are extended. In the first position, needles 202 are spaced from the intersection where the first plane and the second plane meet. In the second position, however, needles 202 pass through the intersection where the first plane and the second plane meet.
- a pair of rails 203 extend above and parallel to the intersection of needle beds 201 and provide attachment points for multiple standard feeders 204 and combination feeders 220.
- Each rail 203 has two sides, each of which accommodates either one standard feeder 204 or one combination feeder 220.
- knitting machine 200 may include a total of four feeders 204 and 220.
- the forward-most rail 203 includes one combination feeder 220 and one standard feeder 204 on opposite sides
- the rearward-most rail 203 includes two standard feeders 204 on opposite sides.
- further configurations of knitting machine 200 may incorporate additional rails 203 to provide attachment points for more feeders 204 and 220.
- feeders 204 and 220 move along rails 203 and needle beds 201 , thereby supplying yarns to needles 202.
- a yarn 206 is provided to combination feeder 220 by a spool
- yarn 206 extends from spool 207 to various yarn guides
- spools 207 may be utilized to provide yarns to feeders 204.
- Standard feeders 204 are conventionally-utilized for a V-bed flat knitting machine, such as knitting machine 200. That is, existing knitting machines incorporate standard feeders 204. Each standard feeder 204 has the ability to supply a yarn that needles 202 manipulate to knit, tuck, and float. As a comparison, combination feeder 220 has the ability to supply a yarn (e.g., yarn 206) that needles 202 knit, tuck, and float, and combination feeder 220 has the ability to inlay the yarn. Moreover, combination feeder 220 has the ability to inlay a variety of different strands (e.g., filament, thread, rope, webbing, cable, chain, or yarn). Accordingly, combination feeder 220 exhibits greater versatility than each standard feeder 204.
- a yarn e.g., yarn 206
- combination feeder 220 has the ability to inlay the yarn.
- combination feeder 220 has the ability to inlay a variety of different strands (e.g., filament, thread, rope, webbing, cable, chain,
- combination feeder 220 may be utilized when inlaying a yarn or other strand, in addition to knitting, tucking, and floating the yarn.
- Conventional knitting machines which do not incorporate combination feeder 220, may also inlay a yarn. More particularly, conventional knitting machines that are supplied with an inlay feeder may also inlay a yarn.
- a conventional inlay feeder for a V-bed flat knitting machine includes two components that operate in conjunction to inlay the yarn.
- components of the inlay feeder are secured to separate attachment points on two adjacent rails, thereby occupying two attachment points.
- an individual standard feeder 204 only occupies one attachment point
- two attachment points are generally occupied when an inlay feeder is utilized to inlay a yarn into a knitted component.
- combination feeder 220 only occupies one attachment point
- a conventional inlay feeder occupies two attachment points.
- knitting machine 200 includes two rails 203, four attachment points are available in knitting machine 200. If a conventional inlay feeder were utilized with knitting machine 200, only two attachment points would be available for standard feeders 204. When using combination feeder 220 in knitting machine 200, however, three attachment points are available for standard feeders 204. Accordingly, combination feeder 220 may be utilized when inlaying a yarn or other strand, and combination feeder 220 has an advantage of only occupying one attachment point.
- Combination feeder 220 is depicted individually in Figures 16- 19 as including a carrier 230, a feeder arm 240, and a pair of actuation members 250. Although a majority of combination feeder 220 may be formed from metal materials (e.g., steel, aluminum, titanium), portions of carrier 230, feeder arm 240, and actuation members 250 may be formed from polymer, ceramic, or composite materials, for example. As discussed above, combination feeder 220 may be utilized when inlaying a yarn or other strand, in addition to knitting, tucking, and floating a yarn. Referring to Figure 16 specifically, a portion of yarn 206 is depicted to illustrate the manner in which a strand interfaces with combination feeder 220.
- metal materials e.g., steel, aluminum, titanium
- portions of carrier 230, feeder arm 240, and actuation members 250 may be formed from polymer, ceramic, or composite materials, for example.
- combination feeder 220 may be utilized when inlaying a yarn or other strand, in addition to knitting, tuck
- Carrier 230 has a generally rectangular configuration and includes a first cover member 231 and a second cover member 232 that are joined by four bolts 233. Cover members 231 and 232 define an interior cavity in which portions of feeder arm 240 and actuation members 250 are located. Carrier 230 also includes an attachment element 234 that extends outward from first cover member 231 for securing feeder 220 to one of rails 203.
- attachment element 234 is depicted as including two spaced protruding areas that form a dovetail shape, as depicted in Figure 17.
- a reverse dovetail configuration on one of rails 203 may extend into the dovetail shape of attachment element 234 to effectively join combination feeder 220 to knitting machine 200.
- second cover member 234 forms a centrally-located and elongate slot 235, as depicted in Figure 18.
- Feeder arm 240 has a generally elongate configuration that extends through carrier 230 (i.e., the cavity between cover members 231 and 232) and outward from a lower side of carrier 230.
- feeder arm 240 includes an actuation bolt 241 , a spring 242, a pulley 243, a loop 244, and a dispensing area 245.
- Actuation bolt 241 extends outward from feeder arm 240 and is located within the cavity between cover members 231 and 232.
- One side of actuation bolt 241 is also located within slot 235 in second cover member 232, as depicted in Figure 18.
- Spring 242 is secured to carrier 230 and feeder arm 240.
- one end of spring 242 is secured to carrier 230, and an opposite end of spring 242 is secured to feeder arm 240.
- Pulley 243, loop 244, and dispensing area 245 are present on feeder arm 240 to interface with yarn 206 or another strand.
- pulley 243, loop 244, and dispensing area 245 are configured to ensure that yarn 206 or another strand smoothly passes through combination feeder 220, thereby being reliably-supplied to needles 202.
- yarn 206 extends around pulley 243, through loop 244, and into dispensing area 245.
- yarn 206 extends out of a dispensing tip 246, which is an end region of feeder arm 240, to then supply needles 202.
- Each of actuation members 250 includes an arm 251 and a plate 252.
- each arm 251 is formed as a one-piece element with one of plates 252. Whereas arms 251 are located outside of carrier 230 and at an upper side of carrier 230, plates 252 are located within carrier 250.
- Each of arms 251 has an elongate configuration that defines an outside end 253 and an opposite inside end 254, and arms 251 are positioned to define a space 255 between both of inside ends 254. That is, arms 251 are spaced from each other.
- Plates 252 have a generally planar configuration. Referring to Figure 19, each of plates 252 define an aperture 256 with an inclined edge 257. Moreover, actuation bolt 241 of feeder arm 240 extends into each aperture 256.
- combination feeder 220 provides a structure that facilitates a translating movement of feeder arm 240.
- the translating movement of feeder arm 240 selectively positions dispensing tip 246 at a location that is above or below the intersection of needle beds 201 . That is, dispensing tip 246 has the ability to reciprocate through the intersection of needle beds 201 .
- An advantage to the translating movement of feeder arm 240 is that combination feeder 220 (a) supplies yarn 206 for knitting, tucking, and floating when dispensing tip 246 is positioned above the intersection of needle beds 201 and (b) supplies yarn 206 or another strand for inlaying when dispensing tip 246 is positioned below the intersection of needle beds 201 .
- feeder arm 240 reciprocates between the two positions depending upon the manner in which combination feeder 220 is being utilized.
- feeder arm 240 In reciprocating through the intersection of needle beds 201 , feeder arm 240 translates from a retracted position to an extended position. When in the retracted position, dispensing tip 246 is positioned above the intersection of needle beds 201 . When in the extended position, dispensing tip 246 is positioned below the intersection of needle beds 201 . Dispensing tip 246 is closer to carrier 230 when feeder arm 240 is in the retracted position than when feeder arm 240 is in the extended position. Similarly, dispensing tip 246 is further from carrier 230 when feeder arm 240 is in the extended position than when feeder arm 240 is in the retracted position. In other words, dispensing tip 246 moves away from carrier 230 when in the extended position, and dispensing tip 246 moves closer to carrier 230 when in the retracted position.
- an arrow 221 is positioned adjacent to dispensing area 245.
- feeder arm 240 is in the retracted position.
- feeder arm 240 is in the extended position.
- the position of feeder arm 240 may be readily ascertained.
- feeder arm 240 The natural state of feeder arm 240 is the retracted position. That is, when no significant forces are applied to areas of combination feeder 220, feeder arm remains in the retracted position. Referring to Figures 16-19, for example, no forces or other influences are shown as interacting with combination feeder 220, and feeder arm 240 is in the retracted position.
- the translating movement of feeder arm 240 may occur, however, when a sufficient force is applied to one of arms 251 . More particularly, the translating movement of feeder arm 240 occurs when a sufficient force is applied to one of outside ends 253 and is directed toward space 255.
- a force 222 is acting upon one of outside ends 253 and is directed toward space 255, and feeder arm 240 is shown as having translated to the extended position. Upon removal of force 222, however, feeder arm 240 will return to the retracted position. It should also be noted that Figure 20C depicts force 222 as acting upon inside ends 254 and being directed outward, and feeder arm 240 remains in the retracted position.
- feeders 204 and 220 move along rails
- carriage 205 More particularly, a drive bolt within carriage 205 contacts feeders 204 and 220 to push feeders
- the drive bolt may either contact one of outside ends 253 or one of inside ends 254 to push combination feeder 220 along needle beds 201 .
- feeder arm 240 translates to the extended position and dispensing tip 246 passes below the intersection of needle beds 201 .
- feeder arm 240 remains in the retracted position and dispensing tip 246 is above the intersection of needle beds 201 . Accordingly, the area where carriage 205 contacts combination feeder 220 determines whether feeder arm 240 is in the retracted position or the extended position.
- FIGS 19-20B depict combination feeder 220 with first cover member 231 removed, thereby exposing the elements within the cavity in carrier 230.
- Figure 19 depicts Figure 19 with Figures 20A and 20B, the manner in which force 222 induces feeder arm 240 to translate may be apparent.
- force 222 acts upon one of outside ends 253
- one of actuation members 250 slides in a direction that is perpendicular to the length of feeder arm 240. That is, one of actuation members 250 slides horizontally in Figures 19-20B.
- the movement of one of actuation members 250 causes actuation bolt 241 to engage one of inclined edges 257.
- actuation bolt 241 rolls or slides against inclined edge 257 and induces feeder arm 240 to translate to the extended position.
- spring 242 pulls feeder arm 240 from the extended position to the retracted position.
- combination feeder 220 reciprocates between the retracted position and the extended position depending upon whether a yarn or other strand is being utilized for knitting, tucking, or floating or being utilized for inlaying.
- Combination feeder 220 has a configuration wherein the application of force 222 induces feeder arm 240 to translate from the retracted position to the extended position, and removal of force 222 induces feeder arm 240 to translate from the extended position to the retracted position. That is, combination feeder 220 has a configuration wherein the application and removal of force 222 causes feeder arm 240 to reciprocate between opposite sides of needle beds 201 .
- outside ends 253 may be considered actuation areas, which induce movement in feeder arm 240.
- the actuation areas may be in other locations or may respond to other stimuli to induce movement in feeder arm 240.
- the actuation areas may be electrical inputs coupled to servomechanisms that control movement of feeder arm 240. Accordingly, combination feeder 220 may have a variety of structures that operate in the same general manner as the configuration discussed above.
- knitting machine 200 operates to manufacture a knitted component.
- FIG 21 A a portion of knitting machine 200 that includes various needles 202, rail 203, standard feeder 204, and combination feeder 220 is depicted. Whereas combination feeder 220 is secured to a front side of rail 203, standard feeder 204 is secured to a rear side of rail 203. Yarn 206 passes through combination feeder 220, and an end of yarn 206 extends outward from dispensing tip 246.
- any other strand e.g., filament, thread, rope, webbing, cable, chain, or yarn
- Another yarn 21 1 passes through standard feeder 204 and forms a portion of a knitted component 260, and loops of yarn 21 1 forming an uppermost course in knitted component 260 are held by hooks located on ends of needles 202.
- the knitting process discussed herein relates to the formation of knitted component 260, which may be any knitted component, including knitted components that are similar to knitted components 130 and 150. For purposes of the discussion, only a relatively small section of knitted component 260 is shown in the figures in order to permit the knit structure to be illustrated. Moreover, the scale or proportions of the various elements of knitting machine 200 and knitted component 260 may be enhanced to better illustrate the knitting process.
- Standard feeder 204 includes a feeder arm 212 with a dispensing tip 213.
- Feeder arm 212 is angled to position dispensing tip 213 in a location that is (a) centered between needles 202 and (b) above an intersection of needle beds 201 .
- Figure 22A depicts a schematic cross- sectional view of this configuration. Note that needles 202 lay on different planes, which are angled relative to each other. That is, needles 202 from needle beds 201 lay on the different planes. Needles 202 each have a first position and a second position. In the first position, which is shown in solid line, needles 202 are retracted. In the second position, which is shown in dashed line, needles 202 are extended.
- needles 202 are spaced from the intersection where the planes upon which needle beds 201 lay meet.
- needles 202 are extended and pass through the intersection where the planes upon which needle beds 201 meet. That is, needles 202 cross each other when extended to the second position.
- dispensing tip 213 is located above the intersection of the planes. In this position, dispensing tip 213 supplies yarn 21 1 to needles 202 for purposes of knitting, tucking, and floating.
- Combination feeder 220 is in the retracted position, as evidenced by the orientation of arrow 221 .
- Feeder arm 240 extends downward from carrier 230 to position dispensing tip 246 in a location that is (a) centered between needles 202 and (b) above the intersection of needle beds 201 .
- Figure 22B depicts a schematic cross-sectional view of this configuration. Note that dispensing tip 246 is positioned in the same relative location as dispensing tip 213 in Figure 22A.
- standard feeder 204 moves along rail 203 and a new course is formed in knitted component 260 from yarn 21 1 . More particularly, needles 202 pulled sections of yarn 21 1 through the loops of the prior course, thereby forming the new course. Accordingly, courses may be added to knitted component 260 by moving standard feeder 204 along needles 202, thereby permitting needles 202 to manipulate yarn 21 1 and form additional loops from yarn 21 1 .
- feeder arm 240 now translates from the retracted position to the extended position, as depicted in Figure 21 C.
- feeder arm 240 extends downward from carrier 230 to position dispensing tip 246 in a location that is (a) centered between needles 202 and (b) below the intersection of needle beds 201 .
- Figure 22C depicts a schematic cross-sectional view of this configuration. Note that dispensing tip 246 is positioned below the location of dispensing tip 246 in Figure 22B due to the translating movement of feeder arm 240.
- combination feeder 220 moves along rail 203 and yarn 206 is placed between loops of knitted component 260. That is, yarn 206 is located in front of some loops and behind other loops in an alternating pattern. Moreover, yarn 206 is placed in front of loops being held by needles 202 from one needle bed 201 , and yarn 206 is placed behind loops being held by needles 202 from the other needle bed 201 . Note that feeder arm 240 remains in the extended position in order to lay yarn 206 in the area below the intersection of needle beds 201 . This effectively places yarn 206 within the course recently formed by standard feeder 204 in Figure 21 B.
- standard feeder 204 moves along rail 203 to form a new course from yarn 21 1 , as depicted in Figure 21 E.
- yarn 206 is effectively knit within or otherwise integrated into the structure of knitted component 260.
- feeder arm 240 may also translate from the extended position to the retracted position.
- Figures 21 D and 21 E show separate movements of feeders 204 and 220 along rail 203. That is, Figure 21 D shows a first movement of combination feeder 220 along rail 203, and Figure 21 E shows a second and subsequent movement of standard feeder 204 along rail 203.
- feeders 204 and 220 may effectively move simultaneously to inlay yarn 206 and form a new course from yarn 21 1 .
- Combination feeder 220 moves ahead or in front of standard feeder 204 in order to position yarn 206 prior to the formation of the new course from yarn 21 1 .
- knitted components 130 and 150 may be formed by utilizing combination feeder 220 to effectively insert inlaid strands 132 and 152 into knit elements 131 .
- inlaid strands may be located within a previously formed course prior to the formation of a new course.
- feeder arm 240 now translates from the retracted position to the extended position, as depicted in Figure 21 F.
- Combination feeder 220 then moves along rail 203 and yarn 206 is placed between loops of knitted component 260, as depicted in Figure 21 G.
- standard feeder 204 moves along rail 203 to form a new course from yarn 21 1 , as depicted in Figure 21 H.
- yarn 206 is effectively knit within or otherwise integrated into the structure of knitted component 260.
- feeder arm 240 may also translate from the extended position to the retracted position.
- yarn 206 forms a loop 214 between the two inlaid sections.
- inlaid strand 132 repeatedly exits knit element 131 at perimeter edge 133 and then re-enters knit element 131 at another location of perimeter edge 133, thereby forming loops along perimeter edge 133, as seen in Figures 5 and 6.
- Loop 214 is formed in a similar manner. That is, loop 214 is formed where yarn 206 exits the knit structure of knitted component 260 and then reenters the knit structure.
- standard feeder 204 has the ability to supply a yarn (e.g., yarn 21 1 ) that needles 202 manipulate to knit, tuck, and float.
- Combination feeder 220 has the ability to supply a yarn (e.g., yarn 206) that needles 202 knit, tuck, or float, as well as inlaying the yarn.
- the above discussion of the knitting process describes the manner in which combination feeder 220 inlays a yarn while in the extended position.
- Combination feeder 220 may also supply the yarn for knitting, tucking, and floating while in the retracted position. Referring to Figure 21 1, for example, combination feeder 220 moves along rail 203 while in the retracted position and forms a course of knitted component 260 while in the retracted position.
- combination feeder 220 may supply yarn 206 for purposes of knitting, tucking, floating, and inlaying.
- An advantage to combination feeder 220 relates, therefore, to its versatility in supplying a yarn that may be utilized for a greater number of functions than standard feeder 204
- combination feeder 220 to supply yarn for knitting, tucking, floating, and inlaying is based upon the reciprocating action of feeder arm 240.
- dispensing tips 213 and 246 are at identical positions relative to needles 220.
- both feeders 204 and 220 may supply a yarn for knitting, tucking, and floating.
- dispensing tip 246 is at a different position.
- combination feeder 220 may supply a yarn or other strand for inlaying.
- An advantage to combination feeder 220 relates, therefore, to its versatility in supplying a yarn that may be utilized for knitting, tucking, floating, and inlaying.
- the upper course of knitted component 260 is formed from both of yarns 206 and 21 1 . More particularly, a left side of the course is formed from yarn 21 1 , whereas a right side of the course is formed from yarn 206. Additionally, yarn 206 is inlaid into the left side of the course.
- standard feeder 204 may initially form the left side of the course from yarn 21 1 .
- Combination feeder 220 then lays yarn 206 into the right side of the course while feeder arm 240 is in the extended position. Subsequently, feeder arm 240 moves from the extended position to the retracted position and forms the right side of the course. Accordingly, combination feeder may inlay a yarn into one portion of a course and then supply the yarn for purposes of knitting a remainder of the course.
- Figure 24 depicts a configuration of knitting machine 200 that includes four combination feeders 220.
- combination feeder 220 has the ability to supply a yarn (e.g., yarn 206) for knitting, tucking, floating, and inlaying.
- standard feeders 204 may be replaced by multiple combination feeders 220 in knitting machine 200 or in various conventional knitting machines.
- Figure 8B depicts a configuration of knitted component 130 where two yarns 138 and 139 are plated to form knit element 131 , and inlaid strand 132 extends through knit element 131 .
- the general knitting process discussed above may also be utilized to form this configuration.
- knitting machine 200 includes multiple standard feeders 204, and two of standard feeders 204 may be utilized to form knit element 131 , with combination feeder 220 depositing inlaid strand 132. Accordingly, the knitting process discussed above in Figures 21 A-21 1 may be modified by adding another standard feeder 204 to supply an additional yarn.
- knitted component 130 may be heated following the knitting process to fuse knitted component 130.
- the portion of knitted component 260 depicted in Figures 21 A- 21 1 has the configuration of a rib knit textile with regular and uninterrupted courses and wales. That is, the portion of knitted component 260 does not have, for example, any mesh areas similar to mesh knit zones 163-165 or mock mesh areas similar to mock mesh knit zones 166 and 167.
- mesh knit zones 163-165 in either of knitted components 150 and 260, a combination of a racked needle bed 201 and a transfer of stitch loops from front to back needle beds 201 and back to front needle beds 201 in different racked positions is utilized.
- mock mesh areas similar to mock mesh knit zones 166 and 167 a combination of a racked needle bed and a transfer of stitch loops from front to back needle beds 201 is utilized.
- inlaid strands 152 follow courses within knit element 151 , some sections of inlaid strand 152 follow wales. For example, sections of inlaid strand 152 that are adjacent to and parallel to inner edge 155 follow wales. This may be accomplished by first inserting a section of inlaid strand 152 along a portion of a course and to a point where inlaid strand 152 is intended to follow a wale. Inlaid strand 152 is then kicked back to move inlaid strand 152 out of the way, and the course is finished.
- inlay strand 152 is again kicked back to move inlaid strand 152 out of the way at the point where inlaid strand 152 is intended to follow the wale, and the course is finished. This process is repeated until inlaid strand 152 extends a desired distance along the wale. Similar concepts may be utilized for portions of inlaid strand 132 in knitted component 130.
- a variety of procedures may be utilized to reduce relative movement between (a) knit element 131 and inlaid strand 132 or (b) knit element 151 and inlaid strand 152. That is, various procedures may be utilized to prevent inlaid strands 132 and 152 from slipping, moving through, pulling out, or otherwise becoming displaced from knit elements 131 and 151 . For example, fusing one or more yarns that are formed from thermoplastic polymer materials to inlaid strands 132 and 152 may prevent movement between inlaid strands 132 and 152 and knit elements 131 and 151 . Additionally, inlaid strands 132 and 152 may be fixed to knit elements 131 and 151 when periodically fed to knitting needles as a tuck element. That is, inlaid strands
- 132 and 152 may be formed into tuck stitches at points along their lengths (e.g., once per centimeter) in order to secure inlaid strands 132 and 152 to knit elements 131 and 151 and prevent movement of inlaid strands 132 and 152.
- knitted components 130 and 150 may be steamed to improve loft and induce fusing of the yarns.
- yarn 138 may be a non-fusible yarn and yarn 139 may be a fusible yarn.
- yarn 139 may melt or otherwise soften so as to transition from a solid state to a softened or liquid state, and then transition from the softened or liquid state to the solid state when sufficiently cooled.
- yarn 139 may be utilized to join (a) one portion of yarn 138 to another portion of yarn 138, (b) yarn 138 and inlaid strand 132 to each other, or (c) another element (e.g., logos, trademarks, and placards with care instructions and material information) to knitted component 130, for example.
- a steaming process may be utilized to induce fusing of yarns in knitted components 130 and 150.
- one method involves pinning one of knitted components 130 and 150 to a jig during steaming.
- An advantage of pinning one of knitted components 130 and 150 to a jig is that the resulting dimensions of specific areas of knitted components 130 and 150 may be controlled. For example, pins on the jig may be located to hold areas corresponding to perimeter edge
- perimeter edge 133 of knitted component 130.
- perimeter edge 133 will have the correct length for a portion of the lasting process that joins upper 120 to sole structure 1 10. Accordingly, pinning areas of knitted components 130 and 150 may be utilized to control the resulting dimensions of knitted components 130 and 150 following the steaming process.
- the knitting process described above for forming knitted component 260 may be applied to the manufacture of knitted components 130 and 150 for footwear 100.
- the knitting process may also be applied to the manufacture of a variety of other knitted components. That is, knitting processes utilizing one or more combination feeders or other reciprocating feeders may be utilized to form a variety of knitted components.
- knitted components formed through the knitting process described above, or a similar process may also be utilized in other types of apparel (e.g., shirts, pants, socks, jackets, undergarments), athletic equipment (e.g., golf bags, baseball and football gloves, soccer ball restriction structures), containers (e.g., backpacks, bags), and upholstery for furniture (e.g., chairs, couches, car seats).
- the knitted components may also be utilized in bed coverings (e.g., sheets, blankets), table coverings, towels, flags, tents, sails, and parachutes.
- the knitted components may be utilized as technical textiles for industrial purposes, including structures for automotive and aerospace applications, filter materials, medical textiles (e.g. bandages, swabs, implants), geotextiles for reinforcing embankments, agrotextiles for crop protection, and industrial apparel that protects or insulates against heat and radiation. Accordingly, knitted
- inlaid strand 152 angle rearwards and extend to heel edges 154.
- these sections of inlaid strand 152 extend from heel edges 154 toward inner edge 155, at least partially around one or more lace apertures 158, and back to heel edges 154.
- some sections of inlaid strand 152 extend from heel edges 154 toward inner edge 155, turn in areas adjacent to and between lace apertures 158, and back to heel edges 154.
- An advantage to this configuration is that the portions of inlaid strand 152 extending between heel edges 154 and inner edge 155 effectively wrap around the heel of the wearer and assist with securing the position of the heel within footwear 100.
- these sections (a) provide support, stability, and structure, (b) assist with securing knitted component 150 or upper 120 around the foot, (c) limit deformation in areas of upper 120 (e.g., imparts stretch-resistance), and (d) operate in connection with lace 122 or another lace to enhance the fit of footwear 100.
- FIGS. 25- 28 Another configuration of footwear 100 is depicted in FIGS. 25- 28, in which inlaid strand 132 of knitted component 130 extends into heel region 103. More particularly, knit element 131 extends from a throat area of upper 120 to heel region 103, and inlaid strand 132 extends through or is inlayed within knit element 131 from the throat area to a rear portion of heel region 103. In addition, the portions of inlaid strand 132 that extend into heel region 103 form a loop in the throat area that extends around one of lace apertures 158 on each of sides 104 and 105, and lace 122 extends through the loop.
- the throat area of upper is generally located in midfoot region 102 and corresponds with an instep region or upper surface of the foot, thereby encompassing portions of upper 120 that include lace apertures 123, tongue 124, and inner edge 135 of knit element 131 . It should also be noted that although sections of inlaid strand 132 extend to heel region 103, other sections of inlaid strand 132 extend between the throat area and the lower area of upper 120 that is adjacent to sole structure 1 10.
- FIG. 29 The configuration of knitted component 130 from FIGS. 25-28 is depicted in FIG. 29. Sections of inlaid strand 132 extend through or are inlayed within knit element 131 from the throat area to each of heel edges 134 on both of sides 104 and 105. Moreover, portions of inlaid strand 132 exit knit element 131 at each of heel edges 134.
- An advantage to this configuration is that each section of inlaid strand 132 that extends between the throat area and heel edges 134 may be independently tensioned, loosened, or otherwise adjusted during the manufacturing process of footwear 100.
- the positions at which end areas of inlaid strand 132 exit knit element 131 correspond with each other on each of sides 104 and 105.
- inlaid strand 132 may contact or be located adjacent to each other at a seam 143, which is formed at heel edges 134.
- inlaid strand 132 or different sections of inlaid strand 132 effectively extends around heel region 103 to enhance the support, stability, structure, and fit of footwear 100 in heel region 103, as well as enhancing the aesthetic appeal of footwear 100.

- inlaid strand 132 may provide consistent support, stability, structure, and fit along a majority of the
- inlaid strand 132 may be positioned immediately adjacent to or spaced from knitted layers 140 and floating yarns 141 .
- inlaid strand 132 may also be substantially parallel to floating yarns 141 .
- inlaid strand 132 may be incorporated into footwear 100 in various ways.
- two portions of inlaid strand 132 form loops around two separate lace apertures 123 and extend to heel region 103.
- FIG. 30B depicts a configuration wherein inlaid strand 132 diverges from ankle opening 121 and extends toward sole structure 1 10 in heel region 103.
- An advantage of this configuration is that this section of inlaid strand 132 may secure sole structure 1 10 against the foot in heel region 103.
- alternating sections of inlaid strand 132 are embedded within knit element 131 and exposed on the exterior surface of upper 120.
- in this configuration separate and spaced apart sections of inlaid strand 132 are exposed and form a portion of the exterior surface between the throat area and the rear portion of heel region 103. That is, multiple covered sections of inlaid strand 132 are located within or embedded in knit element 131 , and other sections of inlaid strand 132 are exposed and form a portion of the exterior surface of upper 120 between the throat area and the rear portion of heel region 103.
- Additional configurations of footwear 100 are depicted in FIGS. 30D and 30E, in which knitted component 130 includes various combinations of the concepts and variations discussed above.
- a method for manufacturing knitted component 130 may utilize aspects of knitting machine 200 and combination feeder 220. The method may also incorporate many of the concepts discussed above relative to FIGS. 21A-21 I, 22A-22C, and 23.
- the method may include utilizing a knitting process to form knit element 131 from at least one yarn, and also inlaying strand 132 into knit element 131 during the knitting process. Once the knitting process is substantially complete, knitted component 130 is incorporated into upper 120 such that inlaid strand 132 extends from the throat area to a rear portion of heel region 103.
- seam 143 is centrally-located in the rear area of heel region 103.
- the end areas of inlaid strand 132 may contact or be located adjacent to each other at seam 143.
- inlaid strand 132 may appear to extend
- FIGS. 31 and 32 depict footwear 100 as having seam 143 located on medial side 105.
- knit element 131 and inlaid strand 132 wrap continuously (i.e., without significant discontinuities or seams) around the rear area of heel region 103 to locate seam 143 on medial side 105.
- knit element 131 and inlaid strand 132 extend from the throat area on lateral side 104 to heel region 103, and extend continuously around heel region 103 to medial side 105.
- the comfort of footwear 100 may be enhanced by removing seam 143 from the rear area of heel region 103 and (b) inlaid strand 132 extends continuously around heel region 103 to further assist with securing knitted component 150 or upper 120 around the heel area of the foot.
- knitted component 130 from FIGS. 31 and 32 is depicted in FIG. 33. Sections of inlaid strand 132 are inlayed within knit element 131 and extend rearward from the throat area on both of sides 104 and 105. Whereas knitted component 130 has a relatively symmetrical aspect in FIG. 29, this configuration is non-symmetrical and has greater length on one side and lesser length on the other side. In effect, the area of knitted
- component 130 associated with lateral side 104 exhibits increased length to extend around heel region 103 and form a portion of medial side 105.
- FIGS. 34-40 illustrate still further embodiments of an article of footwear comprised of a knitted component and a sole structure. These additional embodiments may include some, but not necessarily all, of the features discussed in earlier embodiments. Additionally, these additional embodiments include some features not previously discussed. For purposes of clarity, only some features of the embodiments shown in FIGS. 34-40 are discussed in detail and it will be understood that these embodiments can include some or all of the features described in earlier embodiments, including any combinations of features found in various embodiments discussed above.

- upper 420 may include an integral tongue portion 424. Integral tongue portion 424 may be integrally formed with adjacent portions of upper 420 (e.g., the tongue may be integral with other portions around the throat of upper 420). Alternatively, in other embodiments, upper 420 may incorporate a traditional tongue that is separated from adjacent portions of upper 420. Still other embodiments could include an opening along the throat area without any corresponding tongue. [00154] In some embodiments, upper 420 may be comprised of a knitted component 450, which is depicted separately from the remainder of article 400 in FIG. 37. Referring now to FIG. 37, the primary elements of knitted component 450 are a knit element 451 and an inlaid strand 452.
- Knit element 451 is formed from at least one yarn that is manipulated (e.g., with a knitting machine) to form a plurality of intermeshed loops that define a variety of courses and wales. That is, knit element 451 has the structure of a knit textile. Inlaid strand 452 extends through knit element 451 and passes between the various loops within knit element 451 . Although inlaid strand 452 generally extends along courses within knit element 451 , inlaid strand 452 may also extend along wales within knit element 451 . As with inlaid strand 132, inlaid strand 452 imparts stretch-resistance and, when incorporated into footwear 400, operates in connection with lace 422 to enhance the fit of footwear 400.
- inlaid strand 452 imparts stretch-resistance and, when incorporated into footwear 400, operates in connection with lace 422 to enhance the fit of footwear 400.
- the configuration of knitted component 450 is non-symmetrical and has greater length on one side and lesser length on the other side.
- the configuration of knit element 451 may further be characterized by a perimeter edge 453, a pair of heel edges 454, and an inner edge 455.
- a perimeter edge 453 may be characterized by a pair of heel edges 454, and an inner edge 455.
- inner edge 455 does not extend through throat area 419 of knit element 451 .
- integral tongue portion 424 fills in a region of knit element 451 that extends inside a peripheral region 417 of throat area 419.
- Knit element 451 may have a first surface 456 and an opposite second surface 457 (depicted in FIG. 34 and FIG. 39).
- First surface 456 may form a portion of the exterior surface of upper 420
- second surface 457 may form a portion of the interior surface of upper 420, thereby defining at least a portion of the void within upper 420.
- knit element 451 may have the configuration of a single textile layer in the area of inlaid strand 452. That is, knit element 451 may be a single textile layer between first surface 456 and second surface 457. In other embodiments, however, knit element 451 could be comprised of two or more distinct knit layers.
- inlaid strand 452 repeatedly extends from perimeter edge 453 toward peripheral region 417 of throat area 419, and back to perimeter edge 153. Furthermore, some portions of inlaid strand 452 angle rearwards and extend to heel edges 454. More particularly, some portions of inlaid strand 452 extend from one of heel edges 454 toward peripheral region 455, and back to the same heel edge of heel edges 454.
- inlaid strand 452 extends back and forth between perimeter edge 453 and peripheral region 417, some adjacent portions of inlaid strand 452 may be disposed close together within knit element 451 .
- a first section 461 of inlaid strand 452 may enter perimeter edge 453 and extend through knit element 451 to peripheral region 417 of throat area 419.
- inlaid strand 451 is turned back so that a second section 462 of inlaid strand 452 extends back through knit element 451 to perimeter edge 453.
- first section 461 and second section 462 may be knit along an almost identical path within knit element 451 . It will be understood, however, that in other embodiments, first section 461 and second section 462 could be spaced apart, rather than passing directly adjacent to one another within knit element 451 . For example, other embodiments could use a configuration more similar to previous embodiments in which adjacent sections of an inlaid strand are spaced further apart within the knit element.
- portions of inlaid strand 452 may exit from knit element 451 on first surface 456 to form lace loops 470. Particularly, portions of inlaid strand 452 exit apertures 472 of peripheral region 417 and form lace loops 470. Lace loops 470 may then engage lace 422, as shown for example in FIG. 34. With this arrangement, as lace 422 is tensioned, lace loops 470, and correspondingly inlaid strand 452, are pulled into tension to enhance the fit of upper 420 around a wearer's foot.
- inlaid strand 452 may exhibit greater stretch-resistance. That is, inlaid strand 452 may stretch less than knit element 451 . Given that numerous sections of inlaid strand 452 extend through knit element 451 , inlaid strand 452 may impart stretch-resistance to portions of knitted component 450 forming upper 420 between throat area 419 and the lower area of upper 420. Moreover, placing tension upon lace 422 may impart tension to inlaid strand 452, thereby inducing the portions of upper 420 between the throat area and the lower area to lay against the foot.
- inlaid strand 452 may impart stretch- resistance to portions of upper 420 in heel region 403. Moreover, placing tension upon lace 422 may induce the portions of upper 420 in heel region 403 to lay against the foot. As such, inlaid strand 452 operates in connection with lace 422 to enhance the fit of footwear 400.
- Knit element 451 may incorporate any of the various types of yarn discussed above for knit element 131 and/or knit element 151 .
- Inlaid strand 452 may also be formed from any of the configurations and materials discussed above for inlaid strand 132 and/or inlaid strand 152. Additionally, the various knit configurations discussed relative to Figures 8A and 8B may also be utilized in knitted component 450.
- knit element 451 may have areas formed from a single yarn, two plated yarns, or a fusible yarn and a non-fusible yarn, with the fusible yarn joining (a) one portion of the non-fusible yarn to another portion of the non-fusible yarn or (b) the non-fusible yarn and inlaid strand 452 to each other.
- Embodiments can include provisions to facilitate enhanced fit for an upper, for example, by allowing a wearer to apply tension directly to a portion of an inlaid strand.
- directly tensioning a portion of an inlaid strand may increase tension of a lace in order to improve the fit of the upper against a foot.
- FIGS. 38 through 40 depict schematic rear isometric views of article of footwear 400.
- inlaid strand 452 includes a first section 481 that extends from lateral heel edge 459 to peripheral region 417 of throat area 419, and a second section 482 that extends back from throat area 419 to lateral heel edge 459.
- a lace loop 483 is formed along a portion of inlaid strand 452 between first section 481 and second section 482. Lace loop 483 extends outwardly from an aperture 484 disposed on a rearward most end of peripheral region 417 of throat area 419.
- first section 481 may generally extend through knit element 451 between lateral heel edge 459 to throat area 419 such that first section 481 is effectively confined between first surface 456 (e.g., the exterior surface of upper 420) and second surface 457 (e.g., the interior surface of upper 420).
- second section 482 may extend outwardly from first surface 456 of knit element 451 .
- second section 482 may further comprise a first portion 486 that is disposed between first surface 456 and second surface 457, a second portion 487 that is disposed outwardly (e.g., distally) of first surface 456, and a third portion 489 that is disposed between first surface 456 and second surface 457.
- second portion 487 comprises a length of inlaid strand 452 that is not disposed through knit element 451 .
- second portion 487 may vary.
- second portion 487 has a length in a range between a few millimeters to several centimeters. In some embodiments, second portion 487 could be larger than several centimeters. In some cases, the length of second portion 487 may be selected to ensure that a wearer can grasp second portion 487 by inserting his or her finger between second portion 487 and an exterior portion of knit element 451 .
- inlaid strand 452 may include small portions that emerge on the exterior surface of knit element 451 as inlaid strand 452 extends through the yarn comprising knit element 451 , these small portions may typically have lengths that are much smaller than the length of second portion 487. Specifically, these small portions that may be visible on the exterior surface of knit element 451 may be on order of the spacing between adjacent courses or wales of knit element 451 , or possibly on the order of several times the spacing between adjacent courses or wales.
- Embodiments may include provisions to enhance comfort along regions of knitted component 450 where increased tension and/or pressures may occur.
- first section 481 and second section 482 of inlaid strand 452 extend through a knit collar portion 492 of knitted component 450.
- knit collar portion 492 of knitted component 450 has a different knit configuration than adjacent portions of knit element 451 .
- knit collar portion 492 may have increased elasticity or flexibility to help facilitate inserting a foot into opening 421 .
- knit collar portion 492 could have a substantially similar knit configuration to adjacent portions of knit element 451 .
- some embodiments may include a knit collar portion 492 that varies in thickness.
- knit collar portion 492 comprises a first knit portion 494 having a first thickness 498 and a second knit portion 495 having a second thickness 499.
- first thickness 498 is substantially greater than second thickness 499.
- second portion 487 of inlaid strand 452 extends outwardly on first knit portion 494, the increased thickness of first knit portion 494 may help increase cushioning and comfort at a region where increased tension and/or pressure may build up as first portion 486 is used to increase tension in inlaid strand 452 and upper 420.
- knit collar portion 492 may comprise a substantially continuous knit portion.
- differences in thickness between first knit portion 494 and second knit portion 495 may be achieved by varying the knit configuration.
- differences in thickness between first knit portion 494 and second knit portion 495 may be achieved by using more layers for first knit portion 494 than for second knit portion 495.
- different yarns may be used to achieve differences in thickness as well.
- FIG. 40 illustrates a schematic perspective view of first portion 486 of inlaid strand 452 being pulled away from heel region 403 of upper 420.
- first portion 486 is pulled further away from heel region 403, the tension of inlaid strand 452 is increased, including at lace loop portion 483.
- lace loop portion 483 shrinks in size and begins to tug rearwardly on a lace (not shown) disposed through lace loop portion 483.
- a wearer can help tighten lace 422 and therefore upper 420 around the foot.
