Description

  The present invention relates to footwear products incorporating knit components.

  Conventional footwear products generally include two main elements: an upper and a sole structure. The upper is fixed to the sole structure and forms a cavity inside the footwear to receive the foot comfortably and stably. The sole structure is secured to the lower area of the upper so that it lies between the upper and the ground. For example, in athletic footwear, the sole structure may include a midsole and an outsole. The midsole often includes a polymeric foam material that reduces ground reaction forces and reduces stress on the feet and legs when walking, running, and during other walking activities. In addition, the midsole may include fluid-filled chambers, plates, moderators, or other elements that further reduce forces, increase stability, or affect foot movement. The outsole is fixed to the lower surface of the midsole and forms a ground engaging portion of a sole structure formed of a durable wear-resistant material such as rubber. The sole structure may also include an insole disposed within the cavity and proximate to the lower surface of the foot to enhance the comfort of the footwear.

  The upper generally extends around the instep and toe area, along the inside and outside sides of the foot and around the heel area of the foot. In some footwear products, such as basketball footwear and boots, the upper may extend upward and around the ankle to provide support or protection to the ankle. Access to the cavity inside the upper is generally provided by an ankle opening in the heel area of the footwear. To adjust the comfort of the upper, a lace system is often incorporated into the upper, which allows the foot to enter and withdraw the foot from the cavity in the upper. The lacing system also allows the wearer to accommodate specific dimensions of the upper, particularly the circumference, to accommodate various sized feet. In addition, the upper may include a tongue that extends below the lacing system to increase the adjustability of the footwear, and the upper may incorporate a heel counter to limit heel movement.

  Various material elements (eg, woven fabrics, polymer foams, polymer sheets, leather, synthetic leather) are conventionally used in manufacturing uppers. For example, in athletic footwear, the upper may have multiple layers, each containing various joining material elements. By way of example, these material elements may be selected to impart stretch resistance, abrasion resistance, flexibility, breathability, compressibility, comfort and quick drying to different areas of the upper. In order to impart different properties to different areas of the upper, the material elements are often cut into the desired shape and then joined together, usually with sewing or adhesive. Also, the material elements are often joined 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 costs associated with transporting, storing, cutting and joining the material elements can also increase. More waste material from the cutting and sewing process accumulates as the number and type of material elements incorporated into the upper increases. In addition, the greater the number of material elements in the upper, the more difficult it may be to recycle than an upper formed from fewer and fewer material elements. Therefore, by reducing the number of material elements used for the upper, waste can be reduced while improving the manufacturing efficiency and recyclability of the upper.

  The following description and the accompanying drawings disclose various concepts related to the manufacture of knit components and knit components. Although the knitted component may be used in a variety of products, an article of footwear incorporating one or more knitted components is disclosed below as an example.

  FIGS. 1-17 illustrate an embodiment of an article of footwear that incorporates a knit component that includes one or more single fiber sections formed in a unitary knit structure with the rest of the knit component. Any individual feature of the knitted components described herein may be used in combination in different configurations of the footwear product or may be provided separately. In addition, any feature may be optional and may not be included in any particular embodiment of the knit component.

  FIGS. 1-4 show an embodiment of an article of footwear 100, also referred to simply as product 100. FIG. In some embodiments, the footwear product 100 includes a sole structure 110 and an upper 120. Although product 100 is illustrated as having a general configuration suitable for running, concepts related to product 100 include, for example, soccer shoes, baseball shoes, basketball shoes, cycling shoes, football shoes, tennis shoes, training shoes. It may also apply to a variety of other athletic footwear types, including walking shoes and hiking boots. This concept may also be applied to types of footwear that are generally considered non-athletic, including dress shoes, loafers, sandals and work shoes. Accordingly, the concepts disclosed with respect to product 100 may be applied to a variety of footwear types.

  For reference, as shown in FIGS. 1, 2, and 3, the product 100 is roughly divided into three regions, a foot tip region 10, a midfoot region 12, and a heel region 14. The toe region 10 generally includes a portion of the product 100 corresponding to the toes and joints connecting the metatarsals and phalanges. The midfoot region 12 generally includes the portion of the product 100 that corresponds to the foot arch. The heel region 14 generally corresponds to the back of the foot including the ribs. The product 100 also includes an outer side 16 and an inner side 18 that extend through the toe region 10, the midfoot region 12, and the heel region 14 and correspond to both sides of the product 100. More specifically, the outer side portion 16 corresponds to the outer portion of the foot (that is, the surface facing away from the opposite foot), and the inner side portion 18 corresponds to the inner portion of the foot (that is, the opposite foot). Facing side).

  The toe region 10, midfoot region 12 and heel region 14, as well as the outer side 16 and inner side 18 are not intended to delimit the exact area of the product 100. Rather, the toe region 10, the midfoot region 12, the heel region 14, as well as the outer side 16 and the inner side 18 are intended to represent a general area of the product 100 to assist in the following description. doing. In addition to the product 100, the toe region 10, the midfoot region 12, the heel region 14, and the outer side 16, the inner side 18 may also be applied to the sole structure 110, the upper 120 and their individual elements. Good.

  In an embodiment, the sole structure 110 is secured to the upper 120 and extends between the foot and the ground when the product 100 is worn. In some embodiments, the sole structure 110 may include one or more components including a midsole, an outsole, and / or an insole or insole. In an embodiment, the sole structure 110 may include an outsole 112 that is secured to the lower surface of the upper 120 and / or a base that is configured to secure the sole structure 110 to the upper 120. In some embodiments, the outsole 112 may be formed from a wear-resistant rubber material that is textured to provide traction. This configuration of the sole structure 110 provides one example of a sole structure that may be used in connection with the upper 120, although various conventional or unconventional other configurations of the sole structure 110 may be used. Good. Thus, in other embodiments, the characteristics of any sole structure used with sole structure 110 or upper 120 may vary.

  For example, in other embodiments, the sole structure 110 may include a midsole and / or insole. The midsole may be secured to the lower surface of the upper, and in some cases, when it is compressed between the foot and the ground when walking, running, or during other walking activities, It may be formed from a compressible polymer foam element (eg, polyurethane or ethyl vinyl acetate foam) that weakens the force (ie, becomes a cushioning material). In other cases, the midsole may incorporate a plate, moderator, fluid-filled chamber, lasting element, or motion control member that further weakens the force, increases stability, or affects foot movement. In yet other cases, the midsole may be formed primarily from a fluid-filled chamber positioned within the upper and positioned below the underside of the foot to enhance product comfort.

  In some embodiments, the upper 120 defines a cavity within the product 100 for receiving and securing a foot to the sole structure 110. The cavity is shaped to accommodate the foot and extends along the lateral side of the foot, along the medial side of the foot, above the foot, around the heel, and below the foot. Upper 120 includes an outer surface 121 and an opposite inner surface 122. The outer side 121 is outward and faces away from the product 100, while the inner side 122 is inward and defines the majority or a relatively large portion of the cavity in the product 100 for receiving the foot. Further, the inner side surface 122 may contact the foot or the sock covering the foot.

  Upper 120 may also include a collar 123 that is disposed at least in heel region 14 to form throat opening 140. Access to the cavity is provided by the throat opening 140. More specifically, the foot may enter the upper 120 through the throat opening 140 formed by the collar 123, and the foot may be withdrawn from the upper 120 through the throat opening 140 formed by the collar 123. In some embodiments, the instep area 150 is forward of the collar 123 and ankle opening 140 in the heel area 14 and adjacent to the toe area 10 above the area corresponding to the instep of the midfoot area 12. It extends to the area to do.

  In some embodiments, the upper 120 may include a tongue 152. The tongue 152 may be disposed between the outer side 16 and the inner side 18 of the upper 120 through the instep region 150. In the embodiment, the bellows part 152 is integrally attached to a part of the upper 120 along the outer side part and the inner side part through the instep region 150 and is formed in an integral knit structure with a part of the upper part 120. May be. Thus, as shown in the figure, the upper 120 may extend substantially continuously across the instep area 150 between the outer side 16 and the inner side 18. In other embodiments, the bellows portion 152 is located on the outer side through the instep region 150 such that the bellows portion 152 is movable within the opening between the outer and inner portions on both sides of the instep region 150. And may be separated along the inner side portion.

  The laces 154 extend through the plurality of lace openings 153 in the upper 120 and allow the wearer to adjust the dimensions of the upper 120 to accommodate various proportions of the foot. In some embodiments, the lace 154 may extend through a lace opening 153 that is disposed along either side of the instep region 150. More specifically, the lace 154 allows the wearer to tighten the upper 120 around the foot, and the lace 154 facilitates access to and from the cavity (ie, through the throat opening 140). Allows the wearer to loosen the upper 120. In addition, the tongue 152 of the upper 120 in the instep area 150 extends below the lace 154 to increase the comfort of the product 100.

  The lace 154 is shown with the product 100 in FIG. 1, but the lace 154 is omitted in FIGS. 2-4 for clarity. In a further configuration, the upper 120 includes (a) a heel counter that increases stability in the heel region 14, (b) a toe guard formed from an abrasion resistant material in the toe region 10, and (c) a logo, trademark, and caution. It may include additional elements such as tags that describe matter and material information.

  In some embodiments, as described in more detail below, upper 120 may include one or more portions that include monofilament strands. Single fiber strands may be made from a plastic or polymer material extruded to form single fiber strands. In general, monofilament strands are lightweight and may have a high tensile strength, that is, they can withstand a significant degree of stress before being pulled or broken, so that the upper 120 has a large amount or degree of Provides stretch resistance. In embodiments, the portion of upper 120 that includes single fiber strands may be disposed in one or more single fiber sections 160.

  In some embodiments, the monofilament area 160 may be located at various portions of the upper 120. In an embodiment, the one or more monofilament areas 160 may be located in a portion of the product 100 where the upper 120 is generally flat with respect to the wearer's foot disposed within the upper 120. In this embodiment, the single fiber section 160 includes an inner single fiber portion 162 provided on the inner side portion 18 of the upper 120 and an outer single fiber portion 166 provided on the outer side portion 16 of the upper 120. The inner single fiber portion 162 and the outer single fiber portion 166 may be generally disposed in the midfoot region 12. In some embodiments, the monofilament area 160 may further include a toe monofilament portion 164 that is provided in front of the instep area 150 of the toe area 10 of the upper 120.

  In some embodiments, the single fiber sections 160 may be substantially continuous between each single fiber section 160 across the upper 120. For example, in an embodiment, the inner single fiber portion 162 may be continuous with the foot single fiber portion 164, and the outer single fiber portion 166 may be continuous with the foot single fiber portion 164. With this configuration, the monofilament zone 160 may form a substantially continuous zone that extends from the outer side 16 to the upper side 120 beyond the toe region 10 to the inner side 18. In other embodiments, each monofilament zone 160 is discontinuous with other monofilament zones 160 provided in the upper 120, including the inner monofilament portion 162, the toe monofilament portion 164 and / or the outer monofilament portion 166. It may be. In embodiments where the single fiber sections 160 are discontinuous, each single fiber section 160, eg, the inner single fiber section 162, the toe single fiber section 164 and / or the outer single fiber section 166, depends on the rest of the upper 120. It may be surrounded or surrounded.

  Many conventional footwear uppers are formed from a plurality of material elements (eg, fabric, polymer foam, polymer sheet, leather, synthetic leather) that are joined together, for example, by sewing or gluing. In contrast, in some embodiments, the majority of the upper 120 is formed from the knit component 130, as described in more detail below. The knitted component 130 may be manufactured, for example, in a flat knitting process, passing through the toe region 10, the midfoot region 12 and the heel region 14, respectively, along both the outer side 16 and the inner side 18. , Extending over the toe region 10 and around the heel region 14.

  In an embodiment, the knit component 130 forms substantially all of the upper 120, including most or relatively large portions of the outer surface 121 and the inner surface 122, thereby forming a portion of the cavity within the upper 120. Define. In some embodiments, the knitted component 130 may also extend under the foot. However, in other embodiments, a base portion of the upper 120 that has a strobed insole or a thin sole-like piece of material secured to the knit component 130 and extends under the foot for attachment to the sole structure 110. Form. In addition, as depicted in FIG. 4, a seam 129 extends vertically through the heel region 14 to join the edges of the knitted component 130.

  Although seams may be present on the knitted component 130, most of the knitted components 130 have a substantially seamless configuration. Further, the knit component 130 may be formed as an integral knit structure.

  As used herein, a knitted component (eg, knitted component 130) is defined as being formed with a “unitary knit structure” when formed as a one-piece element by a knitting process. That is, the knitting process substantially forms the various features and structures of the knitted component 130 without requiring significant additional manufacturing steps or processes. Using a unitary knit structure, a knit component, strand, or structure or element having a structure or element that includes one or more courses of yarn includes at least one common course (ie, shares a common yarn). ), And / or other knitted materials that are joined to include a substantially continuous course between each of the structures or elements. With this configuration, a one-piece element with a unitary knit structure is provided.

  Although some of the knitted components 130 may be joined together after the knitting process (eg, the edges of the knitted components 130 are joined together), the knitted components 130 are still formed as a one-piece knitted element, so It is formed with an integral knit structure. Also, if other elements are added after the knitting process (eg, laces, logos, trademarks, notes with notes and material information, structural elements), the knit component 130 is still formed of knit components. ing.

  The knitted component 130 may incorporate various types of yarns that impart different properties to individual areas of the upper 120. That is, one area of the knitted component 130 may be formed from a first type of yarn that imparts a first set of properties, and another area of the knitted component 130 imparts a second set of properties. You may form from the 2nd kind of yarn. In this configuration, the properties of the entire upper 120 may be varied by selecting unique yarns for different areas of the knit component 130. The properties that a particular type of yarn will impart to an area of the knitted component 130 will depend in part on the materials that form the various filaments and fibers within the yarn.

  For example, cotton has a soft hand, natural beauty and biodegradability. Elastane and stretchable polyester each have considerable stretchability and resilience, and stretchable polyester also has recyclability. Rayon has high gloss and moisture absorption. Wool also has high hygroscopicity in addition to heat insulation and biodegradability. Nylon is a durable, wear-resistant material with relatively high strength. Polyester is a hydrophobic material that also has a relatively high durability.

  In addition to the material, other aspects of the yarn selected for the knitted component 130 may affect the properties of the upper 120. For example, the yarns forming the knitted component 130 may be monofilament yarns or multifilament yarns. The yarn may also include individual filaments, each formed from a different material. In addition, the yarn may include filaments that are each formed from two or more different materials, such as a composite yarn that has a sheath core configuration, or a half of two types of filaments that are formed from different materials. Good. Different twists and degrees of crimp, and different deniers may also affect the properties of the upper 120. Thus, both the material forming the yarn and the other side of the yarn may be selected to impart various properties to the individual areas of the upper 120.

  In some configurations of the knitted component 130, the material forming the yarn may be non-fusible or fusible. For example, the non-fusion yarn may be formed substantially from a thermoset polyester material, and the fusion yarn may be at least partially formed from a thermoplastic polyester material. When the fused yarn is heated and fused to the non-fused yarn, this process has the effect of stiffening or curing the structure of the knit component 130. Also, joining portions of the non-fusion yarn using the fusion yarn has the effect of fixing or locking the relative position of the non-fusion yarn within the knit component 130, thereby providing stretch resistance and rigidity. May be given. That is, portions of the non-fused yarn will not slip relative to each other when fused with the fused yarn, thereby preventing distortion or permanent stretching of the knitted component 130 due to relative movement of the knitted structure. Good. Another feature of using a fusing yarn for a portion of the knitted component 130 involves limiting the ability to unravel if a portion of the knitted component 130 has been damaged or one of the non-fusing yarns has broken. . Accordingly, the area of the knitted component 130 may be constructed using both fused and non-fused yarns in the knitted structure.

  In an embodiment, the upper 120 may include a first type of yarn that is knitted to form portions of the knitted component 130 other than the monofilament zone 160. The monofilament section 160 of the upper 120 may be formed by knitting with monofilament strands to form a knitted component 130 of a unitary knit structure with a portion knitted with a first type of yarn. That is, the monofilament area 160 is formed in an integral knit structure with the rest of the knit component 130 to be a one-piece element.

  In some embodiments, the knitted component 130 may include one or more boundary zones. The boundary zone defines the portion of the knitted component 130 where the yarn used to knit the knitted component 130 transitions from one yarn type to another. For example, the knitted component 130 may transition from a first type of yarn to a single fiber strand that forms a single fiber section 160 at one or more boundary zones of the upper 120.

  In an embodiment, the first type of yarn transitions from a natural or synthetic fiber yarn to a single fiber strand at one or more boundary zones associated with each of the single fiber sections 160. In this embodiment, the inner monofilament portion 162 includes a rear inner boundary 200 provided toward the heel region 14 of the upper 120 where the monofilament strands forming the inner monofilament portion 162 are knitted components. Transition to the first type of yarn used to form the remainder of 130. The inner monofilament portion 162 may further include a top inner boundary 204 and a bottom inner boundary 206. In some embodiments, the upper inner boundary 204 may be disposed along the inner side 18 of the upper 120 and may be spaced from the collar 123 and the throat opening 140 by a first distance D1. In some embodiments, the bottom inner boundary 206 may also be disposed along the inner side 18 of the upper 120 and may be spaced from the sole structure 110 by a second distance D2.

  In some embodiments, the front inner boundary 202 may define a front position of the inner monofilament portion 162 of the upper 120. In embodiments where the monofilament area 160 is substantially continuous, the front inner boundary 202 may simply transition to the toe monofilament portion 164. However, in embodiments where each single fiber section 160 is discontinuous, the front inner boundary 202 may define a transition from the single fiber strand back to the first yarn type. In the discontinuous embodiment, it should be understood that the foot monofilament portion 164 is defined by another boundary zone where the yarn returns again to the monofilament strand.

  Continuing along the upper 120, the toe monofilament portion 164 may include a rear toe boundary 208 and a front toe boundary 209. In some embodiments, the posterior toe boundary 208 may be positioned in front of the instep area 150 and separated by a third distance D3. Similarly, the front foottip boundary 209 may be disposed near the tip of the toe of the product 100 and separated by the fourth distance D4. In this embodiment, the outer monofilament portion 166 includes a rear outer boundary 210 provided toward the heel region 14 of the upper 120, where the monofilament strands forming the outer monofilament portion 166 are of the knitted component 130. Transition to the first type of yarn used to form the rest. The outer single fiber portion 166 may further include a top outer boundary 214 and a bottom outer boundary 216. In some embodiments, the upper outer boundary 214 may be disposed along the outer side 16 of the upper 120 and may be spaced from the collar 123 and the throat opening 140 by a fifth distance D5. In some embodiments, the bottom outer boundary 216 may also be disposed along the outer side 16 of the upper 120 and may be spaced from the sole structure 110 by a sixth distance D6.

  In different embodiments, the distances associated with the first distance D1, the second distance D2, the third distance D3, the fourth distance D4, the fifth distance D5 and / or the sixth distance D6 may vary. Good. For example, in some cases, the first distance D1 and the fifth distance D5 may vary between 1 cm and 4 cm. In an embodiment, the first distance D1 and the fifth distance D5 may be about 2 cm to 3 cm. In some cases, the second distance D2 and the sixth distance D6 may vary between 0.1 cm and 1 cm. In some embodiments, the second distance D2 and the sixth distance D6 may be about 0.25 cm to 0.5 cm. In some cases, the third distance D3 may vary between 1 cm and 4 cm. In some embodiments, the third distance D3 may be about 2 cm to 3 cm. In some cases, the fourth distance D4 may vary between 2 cm and 6 cm. In certain embodiments, the fourth distance D4 may be about 3 cm to 5 cm. In other cases, the first distance D1, the second distance D2, the third distance D3, the fourth distance D4, the fifth distance D5 and / or the sixth distance D6 may be different shapes and / or Alternatively, it may be larger or smaller to provide a sized monofilament area 160.

  In some embodiments, the front outer boundary 212 may define a front position of the outer monofilament portion 166 of the upper 120. Similar to the front inner boundary 202, in embodiments where the monofilament area 160 is substantially continuous, the front outer boundary 212 may simply transition to the toe monofilament portion 164. However, in embodiments where each single fiber section 160 is discontinuous, the front outer boundary 212 may define a transition where the single fiber strand returns to the first yarn type. In the discontinuous embodiment, it should be understood that the foot monofilament portion 164 is defined by another boundary zone where the yarn returns again to the monofilament strand.

  In some embodiments, the inner monofilament portion 162 and the outer monofilament portion 166 may have a similar arrangement on each of the inner side portion 18 and the outer side portion 16 so as to be substantially symmetrical. In these embodiments, the first distance D1 and the fifth distance D5 may be approximately equal. Similarly, the second distance D2 and the sixth distance D6 may be substantially equal.

  However, in other embodiments, each of the inner side portion 18 and the outer side portion 16 may have a single fiber area 160 that is different on each side portion. Accordingly, in the other embodiment, the first distance D1 and the outer monofilament portion 166 and the outer monofilament portion 166 are arranged to be further away or closer to the collar 123 and / or the sole structure 110. Each of the fifth distances D5 may be different and / or the second distance D2 and the sixth distance D6 may be different. In still other embodiments, only one of the inner side 18 or the outer side 16 may include a monofilament zone 160. It should be understood that other configurations of the single fiber section 160 of various sizes, shapes and / or locations may be configured according to the processes described herein.

  In some embodiments, the single fiber sections 160 of the upper 120 are transparent, translucent, or opaque, depending on the characteristics or properties of the materials used to make the single fiber strands that form each single fiber section 160. May be. In one embodiment, a single fiber strand having a diameter of about 0.114 mm is included to form a single fiber region 160, including an inner single fiber portion 162, a foot tip single fiber portion 164, and an outer single fiber portion 166, respectively. May be used to In other embodiments, single fiber strands having larger or smaller diameters may be used. In addition, in other embodiments, different single fiber strands may be used for the individual single fiber sections 160 of the upper 120 to provide different properties or characteristics to each single fiber section 160.

  By incorporating a knitted component 130 having a single fiber section 160 into the upper 120 of the product 100, the single fiber section 160 provides strength, stretch resistance, weight reduction, and / or assists in airflow through the upper 120. Thus, the inside of the product 100 can be given air permeability.

  For example, as illustrated in FIG. 5, the inner single fiber portion 162 and the outer single fiber portion 166 are provided in the middle foot region 12 along each of the inner side portion 18 and the outer side portion 16 of the upper 120. . With this configuration, the inner side 18 and the outer side 16 of the upper 120 may increase the strength and stretch resistance of these areas. In addition, the structure of the inner single fiber portion 162 and the outer single fiber portion 166 allows air to easily pass from the upper 120 into the product 100. For example, when the wearer's feet are arranged along the base portion 500 of the upper 120 in the interior of the product 100, air enters and exits the upper 120 to circulate and assist in providing the product 100 with breathability. Also good.

  Also, by forming the upper 120 having one or more single fiber sections 160, the total weight of the upper 120 is significantly reduced compared to an upper formed entirely from natural or synthetic fiber yarns. For example, in one embodiment, an adult male size 8 upper would weigh about 49 grams when knitted with natural or synthetic fiber yarns. In contrast, the weight of the upper 120 with the single fiber section 160 is only 29 grams of similar size. Therefore, the weight saving associated with using single fiber strands in the single fiber section 160 of the upper 120 is at least 40% lighter. In addition, further weight savings may be achieved to increase the weight reduction by more than 40% by changing the number, shape and / or size of the single fiber sections 160 of the upper 120.

  Referring now to FIGS. 6 and 7, an embodiment of the knit component 130 is shown in a planar or flat configuration. In this embodiment, the knit component 130 has a generally Y-shaped configuration that is outlined by the outer peripheral edge 600. In this embodiment, the outer peripheral edge 600 extends around the knit component 130 from the outer side 16 to the inner side 18. The outer periphery of the knitted component 130 also includes a pair of heel edges 602 provided on each of the outer side 16 and the inner side 18. In an embodiment, the knitted component 130 may further include an inner peripheral edge along the collar 123 associated with and defining the throat opening 140 described above. When incorporated into a footwear product including the product 100, at least a portion of the outer peripheral edge 600 and the heel edge 602 may be applied to the upper surface of the sole structure 110 as a base portion 500 illustrated in FIG. In other embodiments, the knitted component 130 may be joined to a strobed insole or insole for attachment to the sole structure 110. In addition, the heel edges 602 join together and extend perpendicular to the heel region 14 of the product 100 to form a seam 129. In some embodiments of the footwear product, a material element may cover the seam 129 between the heel edges 602 to reinforce the seam 129 and improve the aesthetic appeal of the product.

  The knit component 130 may include an instep area 150 that is formed of a unitary knit structure with the remainder of the upper 120 as described above. In some embodiments, the instep area 150 includes a plurality of lace openings 153 provided in the knit component 130. The lace opening 153 extends through the knit component 130 from the outer surface 121 to the inner surface 122 and is configured to receive a lace including the lace 154. In an embodiment, the lace opening 153 may be formed directly in the knitted component 130 by knitting. However, in other embodiments, the lace opening 153 may include additional reinforcing elements that are added to the knit component 130.

  In various embodiments, the knitted component 130 may incorporate various types of yarns that impart different properties to the individual areas of the upper 120. For example, one area of the knitted component 130 may be formed from a first type of yarn that imparts a first set of properties, and another area of the first knitted component 130 may be a second set of properties. You may form from the 2nd kind of yarn which provides. In this configuration, the properties of the entire upper 120 may be varied by selecting unique yarns for different areas of the knit component 130. In embodiments, as described above, the knit component 130 includes a monofilament area 160. In certain embodiments, the single fiber section 160 may include an inner single fiber portion 162, a foot single fiber portion 164 and / or an outer single fiber portion 166. As explained above, the knitted component 130 is formed in a unitary knitted structure such that each of the areas of the knitted component 130, including the single fiber area 160, is knitted as a one-piece element.

  Referring now to FIG. 7, an enlarged view of portions of the single fiber area 160 along the various boundary zones is shown to illustrate the unitary knit structure of the knit component 130. As explained above, the boundary zone of the knit component 130 defines the portion of the knit component 130 where the yarn used to knit the knit component 130 transitions from one yarn type to another. To do. For example, the knitted component 130 may transition from a first type of yarn 700 to a single fiber strand 701 that forms a single fiber section 160 at one or more boundary zones of the upper 120. In an embodiment, the first type of yarn 700 transitions from a natural or synthetic fiber twist yarn to a single fiber strand 701 at one or more boundary zones associated with each of the single fiber sections 160.

  As illustrated in FIG. 7, at the front foottip boundary 209 of the foot region 10 of the knit component 130, the knit component 130 is separated from the foot single fiber portion 164 formed by the single fiber strand 701. Transition to the rest of the knit component 130 formed by one type of yarn 700. In this embodiment, the course of monofilament strands 701 is joined (eg, by interlooping) to the adjacent course of the first type of yarn 700. That is, the course formed by knitting the single fiber strand 701 is substantially continuous with the course formed by knitting the first type of yarn 700. With this configuration, the monofilament area 160 may be formed in a unitary knit structure with the knit component 130.

  Similarly, adjacent wales of knitted component 130 may also transition from one type of yarn to a different type of yarn in the boundary zone. As illustrated in FIG. 7, at the upper inner boundary 204, the knitted component 130 transitions from the portion formed by the first type of yarn 700 to the inner single fiber portion 162 formed by the single fiber strand 701. To do. In this embodiment, the wales of the first type of yarn 700 are joined to the adjacent wales of the single fiber strand 701. In certain embodiments, the single fiber section 160 may be knitted using an intarsia knitting technique to transition between yarn types along the boundary zone. For example, the wales of the first type of yarn 700 may be joined to the adjacent wales of the single fiber strands 701 by using an interstitial construction technique. With this configuration, the monofilament area 160 may be formed in a unitary knit structure with the knit component 130.

  By forming a knitted component 130 having a monofilament area 160 in a unitary knitted structure, the monofilament area 160 is surrounded by the remainder of the knitted component 130 so as to keep the monofilament area 160 under tension. Or may be surrounded. That is, the first type of yarn 700 may be configured to surround the monofilament area 160 formed by the monofilament strands 701. The first type of yarn 700 may be less elastic than the single fiber strand 701, which is not elastic and stretch resistant, so that the knit component 130 places a slight tension on the monofilament area 160. As such, the portion surrounding the monofilament area 160 may stretch. With this configuration, the tension applied to the monofilament 160 by the perimeter of the knitted component 130 may cause the wearer's feet to become uncomfortable in the monofilament area 160, with the kinks or sudden bends in the monofilament strand 701. Assistance may be provided to prevent or reduce this.

  Different embodiments may provide an article of footwear incorporating knit components having different characteristics. In some embodiments, the footwear product may be constructed using knitted components having different types of monofilament sections in the upper. Depending on the type and location desired, the monofilament area may be varied to give different properties to the upper. For example, in some embodiments, a monofilament zone having an inner layer of natural or synthetic fiber twist yarn may be configured to provide comfort to the wearer's foot.

  In some embodiments, upper 820 may include one or more portions that include monofilament strands, as described above. In an embodiment, the portion of the upper 820 that includes single fiber strands may be disposed in one or more single fiber sections 860. In this embodiment, the single fiber section 860 may include two or more different types of single fiber sections. For example, in certain embodiments, different monofilament areas may have different knit structures. In another embodiment, the different single fiber sections may be formed using a combination of single fiber strands and natural or synthetic fiber twist yarns.

  Similar to the single fiber section 160 described above, the single fiber section 860 may be disposed at various portions of the upper 820. In an embodiment, one or more monofilament areas 860 may be disposed on a portion of the product 800 where the upper 820 hits the wearer's foot that is disposed within the upper 820. In this embodiment, the single fiber section 860 includes an inner single fiber portion 862 provided on the inner side portion 18 of the upper 820 and an outer single fiber portion 866 provided on the outer side portion 16 of the upper 820. The inner single fiber portion 862 and the outer single fiber portion 866 may be generally disposed in the midfoot region 12. In some embodiments, the monofilament area 860 may further include a toe monofilament portion 864 and a heel monofilament portion 868. The toe monofilament part 864 is provided in front of the instep area 850 of the toe region 10 of the upper 820, and the heel monofilament part 868 is provided in the heel area 14. In an embodiment, the heel monofilament portion 868 may extend substantially continuously around the heel region 14 of the upper 820 between the outer side portion 16 and the inner side portion 18.

  In some embodiments, the single fiber sections 860 may be substantially continuous between each single fiber section 860 across the upper 820. For example, in one embodiment, the inner single fiber portion 862 may be continuous with the foot single fiber portion 864, and the outer single fiber portion 866 may be continuous with the foot single fiber portion 864. Similarly, the outer single fiber portion 866 may be continuous with the heel single fiber portion 868, and the inner single fiber portion 862 may be continuous with at least a part of the heel single fiber portion 868. With this configuration, the monofilament zone 860 forms a substantially continuous zone that extends across the upper 820 from the outer side 16 over the foot region 10 to the front inner side 18 of the product 100. Alternatively, a substantially continuous zone may also be formed that extends across the upper 820 from the outer side to beyond the heel region 14 to the rear inner side of the product 100.

  In other embodiments, each single fiber section 860 includes other single fibers provided in the upper 820, including an inner single fiber portion 862, a toe single fiber portion 864, an outer single fiber portion 866, and / or a heel single fiber portion 868. It may be discontinuous with the fiber zone 860. In embodiments where the single fiber sections 860 are discontinuous, each single fiber section 860 may be surrounded or surrounded by the rest of the upper 820.

  The knit component 830 illustrated in FIGS. 8-16 includes additional structures or elements when compared to the knit component 130 described above. In the embodiment, the main elements of the knit component 830 are the knit element 831 and the inlay extension element 832. The knit element 831 may be formed from at least one yarn that is manipulated (eg, using a knitting machine) to form a plurality of intertwined loops that define various courses and wales. That is, the knit element 831 has a knit fabric structure.

  Inlay extension element 832 extends through knit element 831 and passes between the various loops in knit element 831. Inlay stretch element 832 generally extends along a course in knit element 831, but inlay stretch element 832 may extend along a wale in knit element 831. The inlay stretch element 832 may provide stretch resistance and when combined with the product 800 functions with the lace 154 to enhance the fit of the product 800.

In an embodiment, the portion of the inlay extension element 832 may form a loop that functions as a lace opening 853 and may then extend back downward in the vertical direction from the instep area 850 toward the sole structure 110. Good. In addition, if the product 800 is provided with a lace 154, the inlay extension element 832 may be tensioned when the lace 154 is tightened, and the inlay extension element 832 prevents extension of the upper 820. The inlay extension element 832 also assists in securing the upper 820 around the foot and functions with the lace 154 to enhance the fit of the product 800. In some embodiments, the inlay extension element 832 exits the knit element 831 in one or more portions, including portions along the inner and outer sides of the instep region 850, and the outer surface of the upper 820. 821 may be exposed.

  As described above with reference to knitted component 130, knitted component 830 may also include yarns formed from different materials, including any material suitable for forming the yarns described above. Good. In some embodiments, as described above, the knitted component 830 may further include non-fusion yarns and fusion yarns. This process may have the effect of stiffening or curing the structure of the knit component 830 when the fusing yarn is heated and fused to the non-fusing yarn. Also, non-fused yarns can be obtained by joining (a) one part of the non-fused yarn to another part of the non-fused yarn and / or (b) the non-fused yarn and the inlay extension element 832 together. And has the effect of fixing or locking the relative position of the inlay extension element 832 thereby imparting stretch resistance and stiffness. That is, the portions of the non-fused yarn will not slip relative to each other when fused with the fused yarn, thereby preventing distortion or permanent stretching of the knitted element 831 due to relative movement of the knitted structure. In addition, the inlay extension element 832 does not slip relative to the knit element 831, thereby preventing a portion of the inlay extension element 832 from being pulled outward from the knit element 831. Accordingly, the area of the knitted component 830 may be configured using both fused and non-fused yarns within the knitted element 831.

  In some embodiments, the knitted component 830 may include a knitted element 831 having a plurality of knitted layers. The knitted layer associated with the knitted component 830 is partially identical to the knitted element 831 that includes at least one common yarn or monofilament strand that travels back and forth between the knitted layers to join and connect the layers together. It may be a part that overlaps with the spread of. With this configuration, the knitted layers together form a single knitted fabric that is formed in a unitary knitted structure.

  In an embodiment, the knitted element 831 may include at least two knitted layers that are joined together in one or more portions to form a knitted component 830. In some embodiments, the first knitted layer may form the majority of the first side of the knitted component 830 and the second knitted layer may form the majority of the second side of the knitted component 830. In some embodiments, the first knitted layer may be associated with the majority of the outer surface 821 and the second knitted layer may be associated with the majority of the inner surface 822.

The inlay stretch element 832 may be provided with additional strength and support by surrounding or surrounding the single fiber strand 1400.

  In some embodiments, two types of single fiber sections 860, i.e., two knit layers formed from single fiber strands and one knit layer formed from natural or synthetic fiber twist yarns. The knitted layer may be knitted with a knitted structure that forms a plurality of indentations in the knitted layer formed from natural or synthetic fiber yarns during the knitting process. Such a configuration further provides breathability to the interior of the upper 820 while still providing comfort to the wearer's foot along the inner surface 822.

  Suitable knit structures for forming the second type of single fiber section 860 include a 1 × 1 inversion mock mesh knit structure or a 2 × 2 inversion mock mesh structure. In contrast to a mesh knit structure that may be used to form an opening completely through the knit element, including both a first knit layer and a second knit layer, the inverted mock mesh knit structure is a second knit. A recess is formed in the layer (ie, the layer corresponding to the inner surface 822 of the upper 820). An embodiment of a schematic diagram 1700 of looping for knitting an inverted 2 × 2 mock mesh structure is illustrated. In this embodiment, the looping diagram 1700 shows a stitch and motion sequence performed by a knitting machine, such as a flat knitting machine, and creates an inverted 2 × 2 mock mesh structure that creates part of a second type of monofilament zone 860. Form. As illustrated in FIG. 17, spaced dots represent the needles of the knitting machine, and the steps shown represent the direction of yarn or strand movement between the respective needles on the front and back floors of the knitting machine.

  As illustrated in FIG. 17, the single fiber strand 1400 may be used to knit the first knit layer of the single fiber section 860 associated with the outer surface 821 of the upper 820, whereas the natural or synthetic fiber twist yarn 1403 may be used to knit the second knit layer of the single fiber section 860 associated with the inner surface 822 of the upper 820. In contrast to the first knitted layer, the second knitted layer includes a plurality of tack knitting performed with natural or synthetic fiber twist yarns 1403. In this embodiment, the width or gap of the second knitted layer is associated with two needles forming an inverted 2 × 2 mock mesh structure. For example, such an inverted 2 × 2 mock mesh structure may be used to form one or more of the toe single fiber portions 864 and / or heel single fiber portions 868 described above. However, in other embodiments, a larger or smaller knit structure may be provided by creating a gap associated with a greater or lesser number of needles. For example, an inverted 3 × 3 mock mesh structure may be formed by increasing the gap to 3 needles, and an inverted 1 × 1 mock mesh structure may be formed by reducing the gap to 1 needle.

  FIG. 17 illustrates an exemplary embodiment of a knit structure that may be used with the knit component 830 to form part of the monofilament zone 860. Mesh knit structures, mock mesh knit structures, and other suitable knit structures are described above, together with the accompanying loop diagrams for knitting the knit structures for use in this embodiment, and are incorporated herein by reference.
