BACKGROUND
[001] Conventional footwear items generally include two primary elements, a leather and a sole structure. The upper is attached to the sole structure and forms a void inside the shoe to comfortably and securely receive a foot. The sole structure is attached to a lower leather surface in order to be positioned between the leather and the floor. In some sports shoes, for example, the sole structure may include an midsole and an outer sole. The midsole can be formed of a polymer foam material that attenuates floor reaction forces to decrease stresses on the foot and leg during walking, running and other physical activities. The outer sole is attached to a lower surface of the midsole and forms a fitting part with the floor of the sole structure which is formed of a durable and wear-resistant material. The sole structure can also include an insole positioned inside the void and proximal to a lower surface of the foot to enhance shoe comfort.
[002] The leather generally extends over the chest and toe areas, along the medial and lateral sides of the foot, and around the heel area of the foot. In some footwear items, such as basketball shoes and boots, the leather can extend up and around the ankle to provide support or protection for the ankle. Access to the void inside the leather in general is provided by an ankle opening in a heel region of the shoe. A string system is often incorporated into the upper to adjust the fitting of the upper, thereby allowing the foot to enter and remove the void within the upper. The stringing system also allows the user to modify certain leather dimensions, particularly circumference, to accommodate feet with variable dimensions. In addition, the upper may include a tongue that extends under the stringing system to improve shoe adjustability, and the upper may incorporate a buttress to limit heel movement.
[003] Various materials are used conventionally in the manufacture of leather. The upper of sports shoes, for example, can be formed of multiple elements of material. Materials can be selected based on various properties, including stretch resistance, wear resistance, flexibility, air permeability, compressibility and moisture absorption, for example. With reference to an upper of the upper, the toe area and the heel area can be formed of leather, synthetic leather or a rubber material to impart a relatively high degree of wear resistance. Leather, synthetic leather and rubber materials may not exhibit the desired degree of flexibility and air permeability for several other areas outside. In this way, the other areas of the exterior can be formed of a synthetic fabric, for example. The exterior of the leather, therefore, can be formed of numerous elements of material in which each imparts different properties to the leather. An intermediate or central leather layer can be formed of a lightweight polymer foam material that provides cushioning and enhances comfort. Similarly, a leather interior can be formed of a comfortable, moisture-absorbing textile that removes perspiration from the area immediately surrounding the foot. The various material elements and other components can be joined with an adhesive or stitching. In this way, the conventional leather is formed of several elements of material in which each one transmits different properties to different areas of the shoe. SUMMARY
[004] A shoe item can have a leather with a knitted component. In some configurations, the knitted component may include regions with varying degrees of resistance to stretching. In some configurations, the knitted component forms a necklace with a half gauge knitted fabric. In some configurations, the upper includes an inlaid cord with sections that are embedded in the knitted component, and the sections are positioned immediately adjacent to each other. In some configurations, the embedded cord forms a plurality of loops, pairs of loops are positioned immediately adjacent to each other, and a lace extends through the pairs of loops. Additionally, in some configurations, the knitted component includes a thermoplastic polymer material, and the embedded cord is not bonded to the thermoplastic polymer material.

[022] The following discussion and the accompanying figures reveal a shoe item having a leather that includes a knitted component. The shoe item is revealed to have a general configuration suitable for walking or running. Concepts associated with footwear, including leather, can also be applied to a variety of other types of sports shoes, including baseball shoes, basketball shoes, multifunctional training shoes, cycling shoes, American football shoes, soccer shoes walking shoes, sneakers and hiking boots, for example. The concepts can also be applied to types of shoes that are generally considered non-sporting, including dress shoes, loafers, sandals and work boots. The concepts revealed in this document therefore apply to a wide variety of footwear types. General Footwear Structure
[023] As a first example, a shoe item 100 is shown in figures 1-4C as including a sole structure 110 and a leather upper 120. While sole structure 110 is located under and supports a user's foot, the leather upper 120 provides a comfortable and secure foot cover. As such, the foot can be placed into a void in the upper 120 to effectively hold the foot inside the shoe 100 or otherwise join the foot and shoe 100. In addition, the sole structure 110 is attached to a lower area leather upper 120 and extends between the foot and the floor to attenuate floor reaction forces (ie, shock absorber for the foot), provide traction, improve stability and influence foot movements, for example.
[024] For reference purposes, footwear 100 can be divided into three general regions: a forefoot region 101, a midfoot region 102 and a heel region 103. The forefoot region 101 generally covers parts of the footwear 100 corresponding to the forefoot, including the toes and joints connecting the metatarsals with the phalanges. The midfoot region 102 generally comprises parts of the shoe 100 corresponding to the central parts of the foot, including an arch area. The heel region 103 generally comprises parts of the shoe 100 corresponding to the rear of the foot, including the heel and heel bone. Footwear 100 also includes a side side 104 and a medial side 105, which extend through each of the regions 101-103 and correspond to the opposite sides of shoe 100. More particularly, side side 104 corresponds to an external area of the foot (that is, the surface that faces away from the other foot), and the medial side 105 corresponds to an internal area of the foot (that is, the surface that faces the other foot). Regions 101-103 and sides 104-105 are not intended to demarcate precise areas of footwear 100. Instead regions 101-103 and sides 104-105 are intended to represent general areas of footwear 100 to assist in the discussion of follow. In addition to shoes 100, regions 101-103 and sides 104-105 can also be applied to sole structure 110, leather 120 and individual elements thereof.
[025] The primary elements of the sole structure 110 are an midsole 111, an outer sole 112 and an insole 113. The midsole 111 is attached to a lower surface of the upper 120 and can be formed of a compressible polymer foam element ( for example, a polyurethane or ethyl vinyl acetate foam) that attenuates floor reaction forces (ie provides cushioning) when compressed between the foot and the floor during walking, running or other physical activities. In additional configurations, the midsole 111 may incorporate plates, moderators, fluid-filled chambers, durable elements, or motion control elements that additionally attenuate strength, enhance stability or influence foot movements, or the midsole 111 may be formed primarily from a chamber filled with fluid. The outsole 112 is attached to a lower surface of the midsole 111 and can be formed of a wear-resistant rubber material that is textured to impart traction. The insole 113 is located inside the void in the upper 120 and is positioned to extend under a lower surface of the foot to improve the comfort of the shoe 100. As another example, the sole structure 110 can have a configuration disclosed in US patent 6,990 .755 to Hatfield et al., Which was issued on January 31, 2006 and which is fully incorporated into this document by reference. While these configurations for sole structure 110 provide examples of sole structures that can be used in connection with upper 120, a variety of other conventional or unconventional configurations for sole structure 110 can also be used. In this way, the features of the sole structure 110 or any sole structure used with the upper 120 can vary considerably.
[026] Leather 120 extends through each of the 101-103 regions, along both the lateral side 104 and the middle side 105, over the forefoot region 101, around the heel region 103 and over an upper surface of the sole structure 110. When the foot is placed into the void, which is shaped to accommodate the foot, the leather 120 extends along a lateral side of the foot, along a medial side of the foot, over the foot , around the heel and under the foot. Leather 120 includes an outer surface 121 and an opposite inner surface 122. While outer surface 121 faces outward and away from the shoe 100, inner surface 122 faces inward and defines a larger or relatively large portion of the void in leather 120. In addition, the inner surface 121 can be close to the foot or to a sock covering the foot. Leather 120 also includes a collar 123 which is located primarily in the heel region 103 and defines an opening for the void in the leather 120, thereby providing the foot with access to the void. That is, the foot can be inserted into the upper 120 and removed from the upper 120 through the opening formed by collar 123.
[027] Most of the upper 120 is made up of a knitted component 130, which will be discussed in more detail below. Although the knitted component 130 is shown to form substantially the entire upper 120, including both surfaces 121 and 122 and the collar 123, a variety of additional elements can be incorporated into the upper 120. For example, an element fixed by the strobel 124 process is attached to the knitted component 130 and forms a major part of the leather 120 which extends under the foot, as shown in figures 4A-4C. In this configuration, the insole 113 extends over the element fixed by the strobel process 124 and forms a surface on which the foot rests. As an alternative, the knitted component 130 may extend under the foot, thereby replacing some or all of the element fixed by the strobel process 124. Furthermore, a seam 125 extends through the heel region 103 on the medial side 105 to joining edges of knitted component 130. Although knitted component 130 forms parts of both surfaces 121 and 122, a polymer layer or a coating layer can be joined with areas of knitted component 130, as disclosed in the patent application publication US 2012/0246973 to Dua, which is fully incorporated into this document by reference. In additional configurations, the leather upper 120 may also include one or more of (a) a shoelace that helps to tighten the leather upper 120 around the foot, (b) a buttress in the heel region 103 to improve stability, (c) protection of toes in the forefoot region 101 which is formed of a wear-resistant material, and (d) logos, trademarks and notices with instructions for care and material information. In this way, leather 120 can incorporate a variety of other features and elements, in addition to the features and elements discussed in this document and shown in the figures. Knitted Component Configuration
[028] Knitted component 130 is formed using a knitting process, such as flat knitting, and extends across the entire upper 120. Although seams may be present in areas of knitted component 130, most knitted component 130 has a substantially seamless configuration. In addition, the knitted component 130 can be formed of unitary knitting construction. As used in this document, a knitted component (for example, knitted component 130) is defined as being formed by "unitary knitting construction" when formed as a single piece element by means of a knitting process. Knitting process substantially forms the various features and structures of the knitted component 130 without the need for significant additional manufacturing steps or processes. Although parts of the knitted component 130 can be joined together (for example, edges of the knitted component 130 being joined together) , as in seam 125) after the knitting process, the knitted component 130 remains formed from unitary knitting construction because it is formed as a one-piece knitting element. In addition, the knitted component 130 remains formed from knitting construction unitary when other elements (for example, the element fixed by the strobel 124 process, a shoelace, logos, trademarks, notices) are added after the knitting process.
[029] Knitted component 130 is formed as a knitting element and can incorporate various types and combinations of stitches and threads. With reference to the stitches, the yarn forming the knitted component 130 can have one type of stitch in one area of the knitted component 130 and another type of stitch in another area of the knitted component 130. Depending on the types and combinations of stitches used, areas of the knitted component 130 may have a flat knitted fabric structure, a knitted fabric structure, or a ribbed knitted fabric structure, for example. Different types of stitches can affect the physical properties of the knitted component 130, including aesthetics, stretching, thickness, air permeability and abrasion resistance. That is, different types of stitches can transmit different properties to different areas of the knitted component 130. With reference to yarns, the knitted component 130 can have one type of yarn in one area of the knitted component 130 and another type of yarn in one another area of the knitted component 130. Depending on various design criteria, the knitted component 130 can incorporate yarn with deniers, materials (for example, cotton, elastane, polyester, rayon, wool and nylon) and different degrees of interlacing, for example. Different types of yarns can affect the physical properties of the knitted component 130, including aesthetics, stretching, thickness, air permeability and abrasion resistance. That is, different types of yarn can transmit different properties to different areas of the knitted component 130. By combining various types and combinations of stitches and yarns, each area of the knitted component 130 can have specific properties that enhance the comfort, durability and performance of the yarn. footwear 100.
[030] Knitted component 130 is shown separately from footwear 100 and in a planar or flat configuration in figure 5. As previously discussed, each area of knitted component 130 can have specific properties, depending on the types and combinations of stitches and yarns that are used during the knitting process. Although the properties in areas of the knitted component 130 can vary considerably, the knitted component is represented as including a first or collar region 131, a second or central region 132 and a third or peripheral region 133, each of which has different properties and are formed from unitary knitting construction. In general, for example, the collar region 131 has a greater stretching capacity than the central region 132, and the central region 132 has a greater stretching capacity than the peripheral region 133. That is, a pulling force acting on the collar region 131 will cause the knitting component 130 to stretch or stretch greater than that caused by the same pulling force acting on the central region 132. Similarly, a pulling force acting on the central region 132 will cause stretching or stretching on the knitted component 130 greater than that caused by the same tensile force acting on the peripheral region 133. In other words, the collar region 131 has less stretching resistance than the central region 132, and the central region 132 has resistance to stretching less than that of peripheral region 133. It should be noted that although a dashed line is used to separate and define regions 131-133, the dashed line can be used for reference. a not visible in some configurations of the knitted component 130.
[031] The collar region 131 corresponds to the position of collar 123 on leather 120 and forms a circular or tubular structure. When shoe 100 is worn, the collar region 131 extends around or surrounds the wearer's ankle and can be close to the ankle. As noted earlier, collar region 131 exhibits a greater stretching capacity than both regions 132 and 133. An advantage of providing relatively small stretch resistance for collar region 131 is that this area of knitted component 130 it will stretch or otherwise stretch as the foot is inserted into leather 120 and removed from leather 120 through the opening formed by collar 123. Additionally, collar region 131 can remain in a partially stretched state and stay close to the ankle when the footwear 100 is worn, thereby preventing rubbish, pebbles and other debris from entering footwear 100 through collar 123.
[032] Various types of stitches and threads can be used for the collar region 131. As an example, figure 6A represents a loop diagram representing a knitted fabric structure for the collar region 131 that is formed from a first thread 134 and a second thread 135. In order to transmit stretch to the collar region 131, the loop diagram indicates that the collar region 131 is formed as a half gauge knitted fabric. That is, the loop and fold stitches formed by threads 134 and 135 are knitted on each other needle to form gaps or ribs in the knitted fabric structure, thereby facilitating expansion or stretching. In some configurations, forming the collar region 131 as a half-gauge knitted fabric forms a ribbed structure on the knitted component 130. To impart additional stretch to the collar region 131, the first thread 134 may be an elastic thread, such as elastane denier 210 (for example, spandex) covered with two ends of 150 denier polyester thread. In addition, the second thread 135 can be two ends of 150 denier textured polyester thread.
[033] The central region 132 extends out of the collar region 131 and towards a part of the knitted component 130 that is located in the forefoot region 101, thereby corresponding to a throat area of the upper 120 When shoe 100 is worn, the central region 132 extends over an upper surface of the foot and can be close to the upper surface of the foot. As noted earlier, the central region 132 exhibits greater resistance to stretching than that of the collar region 131, but has less resistance to stretching than that of the peripheral region 133. An advantage of imparting a moderate degree of resistance to stretching for the region what is central is that this area of the knitted component 130 will expand or otherwise stretch as the foot is inserted into the upper 120, thereby accommodating feet with various proportions, such as circumference and width. In addition, the central region 132 can remain in a partially stretched state and stay close to the upper surface of the foot when footwear 100 is worn, thereby ensuring a firm fit during running or walking.
[034] Various types of stitches and threads can be used for the central region 132. As an example, figure 6B represents a loop diagram representing a knitted fabric structure for the central region 132 that is formed from the first thread 134. Although the loop diagram indicates that the central region 132 is formed as a knitted fabric of full gauge, the first thread 134 may be an elastic thread that transmits the moderate degree of resistance to stretching to the central region 132. As noted earlier, the first yarn 134 may be denier elastane 210 covered with two ends of denier polyester 150.
[035] The peripheral region 133 forms a remainder of the knitted component 130 and extends at least partially around the central region 132, thereby being located on a periphery of the knitted component 130. When incorporated into the shoe 100, the peripheral region 133 is extends through each of the 101-103 regions, along both the side 104 and the middle side 105, over the forefoot region 101, around the heel region 103. In addition, when shoe 100 is worn, the peripheral region 133 extends along a lateral side of the foot, along a medial side of the foot, over the foot and around the heel. As noted earlier, peripheral region 133 exhibits greater stretching resistance than that of both regions 131 and 132. In addition, peripheral region 133 may exhibit relatively little or no stretching when tensile forces are applied. An advantage of imparting a relatively small degree of stretch to the peripheral region 133 is that this area of the knitted component 130 resists stretching in the upper 120 and ensures a firm fit during running or walking.
[036] Various types of stitches and threads can be used for peripheral region 133. As an example, figure 6C represents a loop diagram representing a fabric structure knitted for peripheral region 133 that is formed from the first thread 134 and from a third yarn 136. Although the first yarn 134 may be an elastic yarn, the greatest resistance to stretching in the peripheral region 133 may be a product of (a) a full gauge knitted fabric represented in the loop diagram and (b) thermoplastic features of the third thread 136. That is, the third thread 136 may incorporate a meltable or thermoplastic polymer material, which becomes soft or softens when heated and returns to a solid state when cooled. More particularly, the thermoplastic polymer material changes from a solid to a soft or liquid state when subjected to sufficient heat, and then the thermoplastic polymer material changes from a soft or liquid state to a solid state when sufficiently cooled. As such, thermoplastic polymer materials are often used to join two objects or elements together. In this case, the thermoplastic polymer material on the third wire 136 can be used to join (a) parts of the third wire 136 to parts of the first wire 134 and (b) parts of the third wire 136 to other parts of the third wire 136. In this way , the thermoplastic polymer material, which can be thermoplastic polyurethane, melts or bonds with the knitted fabric structure and stabilizes the peripheral region 133, thereby minimizing stretching in the peripheral region 133. As an example, the third thread 136 can be two ends of denier elastane 20 covered with 150 denier textured polyester and a meltable or thermoplastic polymer material. It should be noted that, in many shoe configurations 100, the thermoplastic polymer material is substantially absent in the collar region 131 and in the central region 132.
[037] While knitted component 130 can be formed by using a variety of different knitting processes and using a variety of different knitting machines, flat knitting (ie the use of a flat knitting machine) has the ability to forming the knitted component 130 to have the various features discussed above. Flat knitting is a method of producing a knitted material that is rotated periodically (that is, the material is knitted from alternating sides). The two sides (otherwise referred to as faces) of the material are conventionally designated as the right side (that is, the side that faces outward, towards the viewer) and the opposite side (that is, the side that faces inward, away from the observer). Additional information regarding flat knitting and processes that can be used to form knitted component 130 can be found in US patent application publication 2012/0233882 to Huffa and others, which is fully incorporated into this document by reference. Although flat knitting provides a suitable way to form the knitted component 130, a variety of other knitting processes can also be used, depending on the features that are incorporated into the knitted component 130. Examples of other knitting processes that can be used include knitting wide circular tube, narrow circular tube knitting jacquard, single point circular knitting jacquard, double point circular knitting jacquard, warp knitting, warp raschel and bar raschel double needle. Embedded Shoelace Configuration
[038] Another configuration of shoe 100 is shown in figures 7-10C as having many or all of the features discussed above. As such, the knitted component 130 (a) is formed by means of a knitting process, such as flat knitting, and extends across the entire upper 120, (b) can be formed of unit knitting construction, (c) is formed as a knitting element and can incorporate various types and combinations of stitches and yarns. Furthermore, the knitted component 130 can each include the collar region 131, the central region 132 and the peripheral region 133, as well as the relative degrees of stretching discussed above. As an additional feature, this shoe configuration 100 includes a built-in cord 140 that forms several shoelace loops 141, which are configured to receive a shoelace 126, which is represented as passing through the various shoelace loops 141. As in some Conventional shoe items, shoelace 126 passes over upper 120 and between shoelace loops 141 that are located along opposite sides of upper 120. When using shoe 100, shoelace 126 allows the user to modify dimensions of upper 120 to accommodate the proportions of the foot. More particularly, the lace 126 can be manipulated in a conventional manner to allow the user to (a) tighten the leather 120 around the foot and (b) loosen the leather 120 to facilitate insertion and removal of the foot from the void in the leather 120 (this that is, through the opening formed by collar 123).
[039] Parts of the embedded cord 140 are located within the knitted component 130 and can be embedded in the structure of the knitted component 130 during the knitting process. US patent application publication 2012/0233882 for Huffa et al., Which has been referenced above and incorporated into this document, provides discussion of the way in which knitted component 130 can be formed, including the process of embedding or locating otherwise the embedded cord 140 within the knitted component 130. Since the embedded cord 140 is incorporated into the knitted component 130 during the knitting process, the knitted component 130 and the embedded cord 140 can be formed of unitary knitting construction. That is, the knitted component 130 and the embedded cord 140 are formed as a single piece element by means of the knitting process.
[040] The built-in cord 140 passes repeatedly between (a) a leather throat area 120, which corresponds to the location of the lace 126 and the upper surface of the foot and (b) a lower leather area 120, which is adjacent the one where the sole structure 110 is attached to the upper 120. Although parts of the built-in cord 140 are located within the knitted component 130 between the throat area and the lower area, other parts of the built-in cord 140 are exposed or located external to the component knitted 130 in the throat area to form the shoelace loops 141. In this configuration, the built-in cord 140 is tensioned when the shoelace 126 is tightened, and the built-in cord 140 resists stretching in the upper 120. In addition, the built-in cord 140 helps attach the upper 120 around the foot and operate in connection with the shoe 126 to improve the fit of the shoe 100.
[041] Knitted component 130 and embedded cord 140 are shown separately from footwear 100 and in a planar or flat configuration in figure 11. Although the specific locations of embedded cord 140 can vary considerably, embedded cord 140 is represented as being located primarily in peripheral region 133. As discussed earlier, peripheral region 133 exhibits greater resistance to stretching than that of both regions 132 and 133 and may exhibit relatively little or no stretching when placed in tension. In comparison with the peripheral region 133, the embedded cord 140 may exhibit an even greater resistance to stretching. That is, the embedded cord 140 may stretch less than the peripheral region 133 when subjected to the same tensile force. Since numerous sections of the built-in cord 140 extend from the throat area to the lower leather area 120, the built-in cord 140 imparts resistance to stretching to the part of the leather 120 between the throat area and the lower area. In addition, putting tension on the lace 126 can transmit tension to the built-in cord 140, thereby inducing the part of the upper 120 between the throat area and the lower area to be close to the foot. As such, the built-in cord 140 operates in connection with the shoelace 126 to improve the fit of the shoe 100.
[042] Referring to figure 12, the embedded cord 140 is shown as being located within the knitted component 130 and between opposite surfaces of the knitted component 130. Since the surfaces of the knitted component 130 can also form each of the surfaces 121 and 122 when incorporated into footwear 100, the built-in cord 140 will also be located between surfaces 121 and 122. Although each of the sections of the built-in cord 140 that are located within the knitted component 130 can be spaced apart from each other, the sections of the built-in cord 140 forming a single shoelace loop 141 are shown to be located immediately adjacent to each other. As defined herein, sections of embedded cord 140 are "immediately adjacent" to each other when located two millimeters apart. In this configuration, the built-in cord sections extending downwardly from each shoelace loop 141 and towards the sole structure 110 are immediately adjacent to each other. In some configurations, sections of the built-in cord 140 that are immediately adjacent to each other may be in contact or may be separated from one another by one or two wires, for example. In addition, the structure of the knitted component 130 can define a tunnel or channel within the leather 120, and the embedded cord sections extending downwardly from each loop for shoelace 141 can be located within the same tunnel.
[043] As previously discussed, parts of the built-in cord 140 are located inside the knitted component 130, and other parts of the built-in cord 140 are exposed or located outside the knitted component to form the shoelace loops 141. For each shoelace loop 141 , a first section of the embedded cord 140 is located or embedded in the knitted component 130, a second section of the embedded cord 140 forms one of the loops for lace 141, and a third section of the embedded cord 140 is also located or embedded in the knitted component 130. In addition, the first section and the third section are positioned immediately adjacent to each other and extend between the throat area and the lower leather area 120. In some configurations, the first section and the third section can be located within the same area tunnel or channel within the knitted component 130.
[044] Figure 13 represents a loop diagram representing a knitted fabric structure for the areas that include the built-in cord 140. In addition to the built-in cord 140, a fourth wire 137 can be located in this area and have two ends of denier elastane 20 covered with 150 denier textured polyester. The fourth thread 137 has a structure that is similar to that of the third thread 136, but without the meltable or thermoplastic polymer material. An advantage of this configuration is that the embedded cord 140 will remain unconnected with the knitted component 130 or otherwise separated from the knitted component 130 in the peripheral region 133. In addition, the embedded cord 140 can slide or move within the knitted component 130, allowing thus (a) the size of each lace for shoelaces 141 and (b) the tension in parts of the built-in cord 140 are adjusted during the shoe manufacturing process 100.
[045] Another method of ensuring that the embedded cord 140 will remain unattached to the knitted component 130 or otherwise separated from the knitted component 130 concerns the selection of material for the embedded cord 140. As an example, the embedded cord 140 may be formed of a nylon material that does not bond or join with some thermoplastic polymer materials, such as thermoplastic polyurethane. When the embedded cord 140 is formed of nylon, therefore, the fourth cord 137 can be replaced by the third cord 136, which includes the meltable or thermoplastic polymer material, and the embedded cord 140 will not bond with the third cord 136. One advantage of this method is that the number of different types of yarns that are used in the knitted component 130 can be minimized, thereby improving manufacturing efficiency. Various coatings, such as polytetrafluoroethylene (PTFE), can also be used to inhibit bonding between the embedded cord 140 and the meltable or thermoplastic polymer material. As such, selecting the embedded cord 140 to have a material that is incompatible with the thermoplastic polymer material can ensure that the embedded cord 140 will remain unattached to the knitted component 130.
[046] In general, parts of the knitted component 130 may include yarns that are formed at least partially from a thermoplastic polymer material. The knitted component 130 can be heated in such a way that the thermoplastic polymer material connects or melts areas of the knitted component 130, such as in the peripheral region 133. More particularly, the thermoplastic polymer material can connect parts of the threads together to form joined areas or cast. In some configurations, the wire with the thermoplastic polymer material can be joined to itself in the melted areas. In other configurations, the yarn with the thermoplastic polymer material can be joined to other yarns in the melted areas, which may or may not include a thermoplastic polymer material. In either scenario, however, several methods can be used to ensure that the embedded cord 140 remains unattached to the thermoplastic polymer material. In one example, the knitted fabric structure of the knitted component 130 places threads without a thermoplastic polymer material immediately adjacent to the embedded cord 140, thereby forming a divider between the embedded cord 140 and the thermoplastic polymer material. In another example, the embedded cord 140 may include a material that does not form a bond with the thermoplastic polymer material. In this way, various configurations and methods can be used to ensure that the embedded cord 140 will remain separate or not bound to the thermoplastic polymer material.
[047] As with the yarns forming the knitted component 130, the configuration of the embedded cord 140 can also vary significantly. In addition to yarn, the embedded cord 140 can have the configurations of a filament (for example, a monofilament), thread, cable, fabric, fiber or chain, for example. In comparison to the yarns forming the knitted component 130, the thickness of the embedded cord 140 may be greater. In some configurations, the embedded cord 140 may have a significantly greater thickness than the yarns of the knitted component 130. Although the cross sectional shape of the embedded cord 140 may be round, the cross sectional form may also be triangular, quadrangular, rectangular, elliptical or irregular. In addition, the materials forming the built-in cord 140 can include any of the materials for the yarns within the knitted component 130, such as cotton, elastane, polyester, rayon, wool and nylon. As noted earlier, embedded cord 140 may exhibit greater stretch resistance than knitted component 130. As such, materials suitable for embedded cord 140 may include a variety of engineering filaments that are used for high tensile strength applications. , including glass, aramides (e.g., para-aramid and meta-aramid), ultra-high molecular weight polyethylene and liquid crystal polymer. As another example, a braided polyester thread or cable having a diameter of 0.8 mm can also be used as the built-in cord 140.
[048] Lace 126, as noted earlier, passes over leather 120 and between lace loops 141 that are located along opposite sides of leather 120. In fact, lace 126 follows a zigzag path over the upper 120 and between the opposite sides of the upper 120. In various locations on the opposite sides of the upper 120, two shoelace loops 141 overlap each other or are positioned immediately adjacent to each other, as shown in figure 14, and the shoelace 126 traverses both shoelace loops 141 simultaneously. That is, pairs of shoelace loops 141 are used as shoelace receiving elements at each location where shoelace 126 changes direction by repeatedly passing over upper 120. With pairs of shoelace loops 141 being in an overlapping configuration, each one of the pairs of shoelace loops 141 is aligned to form an opening, and shoelace 126 extends through the opening. Although shoelace 126 can pass through a single shoelace loop 141 at each location, an advantage of using pairs of shoelace loops 141 is that the disruption effect of embedded cord 140 can be minimized. That is, when the part of the embedded cord 140 associated with a shoelace loop 141 breaks or otherwise fails, the other shoelace loop 141 can form a shoelace receiving element at each location.
[049] Another configuration of knitted component 130 is shown in figure 15 as including (a) multiple subregions 138 within peripheral region 133 and (b) a plurality of holes 139 that extend through knitted component 130 in areas of central region 132 and peripheral region 133. Sub-regions 138 can be areas where knitted component 130 has different types and combinations of stitches and threads. Each of the subregions 138, therefore, can have different properties, such as stretch resistance, thickness, air permeability and abrasion resistance. Alternatively, subregions 138 may vary only in the color of the yarn that is used, thereby varying the aesthetic of leather 120. In addition to increasing the air permeability of leather 120, holes 139 can also transmit the ability to stretch to the knitted component 130. That is, holes 139 can decrease the stretch resistance of knitted component 130 in specific areas. In this way, various features and structures within the knitted component 130 can vary considerably to provide specific properties for areas of the knitted component 130.
[050] The invention was previously revealed and in the attached figures with reference to a variety of configurations. The intended purpose of the disclosure, however, is to provide an example of the various features and concepts related to the invention, and not to limit the scope of the invention. Those skilled in the art will recognize that numerous variations and modifications can be made to the configurations described above without departing from the scope of the present invention, as defined by the appended claims.
