    FIELD OF THE INVENTION
    [001] The present invention relates to a shoe article and, more particularly, it relates to a shoe article that includes a knitted component with an extensible thread. BACKGROUND OF THE INVENTION
    [002] This section provides basic information related to this disclosure, which is not necessarily state of the art.
    [003] Conventional footwear generally includes two main elements, an upper and a sole structure. The upper is attached to the sole structure and a space is formed inside the shoe that securely and comfortably receives one foot. The sole structure is attached to a lower area of the upper part and is thus positioned between the upper part and the ground. In sports shoes, for example, the sole structure may include an midsole and an outer sole. The midsole often includes a polymeric foam material that attenuates ground reaction forces in order to reduce stresses on the foot and leg during walking, running and other outpatient activities. In addition, the midsole may include chambers filled with fluid, plates, moderators, or other elements that also attenuate forces, increase stability, or influence foot movements. The outer sole is attached to a lower surface of the midsole and provides a support portion on the floor of the sole structure formed from a durable and wear-resistant material, such as rubber. The sole structure can also include an insole positioned inside the space and close to a lower surface of the foot in order to increase the comfort of the shoe.
    [004] The upper part extends, generally, along the areas of the forefoot and toes, along the middle 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 upper part may extend upwards and around the ankle in order to provide support or protection to the ankle. Access to the space inside the upper is usually provided by an ankle space in a region of the heel of the shoe. A shoelace system is often incorporated in the upper part to adjust the upper part, thus allowing the foot to enter and exit the space inside the upper part. The shoelace system also allows the user to modify certain dimensions of the upper part, particularly the perimeter, to accommodate feet with varying sizes. In addition, the upper part may include a tongue that extends under the shoelace system to improve the adaptability of the shoe, and the upper part may include a heel counter to limit the movement of the heel.
    [005] A variety of material elements (for example, textiles, polymeric foam, polymeric sheets, leather, synthetic leather) are conventionally used in the manufacture of the upper. In sports shoes, for example, the upper can have multiple layers that each include a variety of joined material elements. As examples, the material elements can be selected in order to transmit resistance to distension, resistance to wear, flexibility, permeability to air, compression, comfort, and for different areas of the upper part, moisture absorption. In order to give different properties to the different areas of the upper part, material elements are often cut into desired shapes and then attached, usually with sewing or adhesive glue. In addition, material elements are often joined in a layered configuration to give multiple properties to the same areas. As the number and type of material elements included in the upper parts increases, so can the time and cost associated with transporting, storing, cutting, and joining the material elements. Residues from the cutting and sewing processes also accumulate to a greater degree as the number and type of material elements included in the upper parts increase. In addition, the upper part with a greater number of material elements may be more difficult to recycle than the upper part formed from fewer types and numbers of material elements. By decreasing the number of material elements used in the upper part, therefore, the residues can be reduced, while the manufacturing efficiency and the possibility of recycling the upper part increase. SUMMARY
    [006] This section provides a general summary of the disclosure, and is not a comprehensive disclosure of the entire scope or all of its characteristics.
    [007] An upper part of a shoe item, which is configured to be attached to a sole structure, is revealed. The upper part includes a mesh component that has a base portion that is configured to be arranged adjacent to the sole structure. The base portion defines an inner surface and an outer surface of the mesh component. The base portion defines a base portion passage between the inner surface and the outer surface. In addition, the upper part includes an extensible thread that extends through the passage of the base portion.
    [008] In addition, an upper part of a shoe article is disclosed, which is configured to be connected to a sole structure. The upper part includes a mesh component that has a base portion that is configured to be disposed adjacent to the sole structure. The base portion has a first layer of mesh material that defines an inner surface of the base portion, a second layer of mesh material that defines an outer surface of the base portion, and a plurality of spacer threads that extend between and provide the spacing between the first layer and the second layer. A passage of the base portion is defined between the plurality of spacer wires. In addition, an extensible yarn extends through the passage of the base portion.

    [013] Examples of embodiments will now be described entirely with reference to the accompanying drawings. General Discussion of Footwear Article
    [014] Referring initially to FIGS. 1 to 3, a shoe article 100 is illustrated according to the examples of embodiments. Footwear 100 can generally include a sole structure 110 and an upper 120.
    [015] The sole structure 110 is attached to the upper 120 and extends between the foot and the ground when footwear 100 is worn. The sole structure 110 may include a midsole 112 and an outer sole 114, which are layered on top of each other. The midsole 112 may include a compressible elastic material, liquid filled bags, and the like. As such, the midsole 112 can cushion the wearer's foot and mitigate impact and other forces during runs, jumps, and the like. The outsole 114 can be attached to the midsole 112 and can include a wear resistant material, such as rubber and the like. The 114 sole may also include a sole and other traction-enhancing features.
    [016] In addition, the upper part 120 can define a space 122 that receives a foot from the user. In other words, the upper part 120 can define an inner surface 121 that defines the space 122, and the upper part 120 can define an outer surface 123 that faces, in the opposite direction, to the inner surface 121. When the foot of the the user is received inside the space 122, the upper part 120 can, at least partially, encircle and cover the foot of the user.
    [017] Many upper parts of conventional shoes are formed from various material elements (for example, textiles, polymeric foam, polymeric sheets, leather, synthetic leather) that are joined through gluing or sewing, for example. In contrast, at least a portion of the upper part 120 is formed from a mesh component 116 having a unitary mesh construction. The outer limits of the mesh component 116 can be defined by a peripheral edge 199, which is shown in FIGS. 5 and 6. As will be discussed, the mesh component 116 can define at least a portion of the space inside the upper part 120. In addition, the mesh component 116 can define at least a part of the outer surface 123 and / or the inner surface 121 of the upper part 120.
    [018] In some embodiments, the mesh component 116 can define most of the upper part 120. Decreasing the number of material elements used in the formation of the upper part 120 can decrease waste, also increasing the manufacturing efficiency and the possibility top 120 recycling component. As discussed in detail below, the top 120 mesh component 116 of the present disclosure can decrease waste and increase manufacturing efficiency and recyclability. In addition, the 116 mesh component of the upper 120 may incorporate fewer seams or other discontinuities, thus increasing the overall comfort of the shoe 100.
    [019] The 116 mesh component can also have common properties when formed from the same yarn, thread (or thread types) or with similar mesh structures. For example, by using the same yarn in several portions of the 116 mesh component, one can impart durability, strength, elasticity, wear resistance, biodegradability, similar hydrophobic and thermal properties. In addition to physical properties, by using the same yarn in several portions of the 116 mesh component, common aesthetic or tactile properties, such as color, luster and texture, can be imparted. Using the same mesh structures in different portions of the 116 mesh component can also impart common physical and aesthetic properties. Mesh Component Settings
    [020] FIGS. 4 to 6 illustrate various embodiments of mesh components 116, which can be incorporated into footwear articles in a similar manner as the example of the embodiment of FIGS. 1 to 3. The mesh component 116 illustrated in FIGS. 4 to 6 are shown separately from the remainder of footwear 100. However, it should be understood that each of the embodiments of the mesh component 116 described herein can be combined with the footwear elements 100, described above, to form an article of footwear 100 incorporating the 116 mesh component.
    [021] The 116 mesh component can be "unitary mesh construction". As defined herein, and as used in the claims, the term "unitary mesh construction" means that the 116 mesh component is formed as a single piece element through the knitting process. That is, the knitting process substantially forms the various characteristics and structures of the 116 mesh component without the need for significant additional manufacturing steps or processes. A unitary mesh construction can be used to form a mesh component having structures or elements that include one or more strands of yarn or other mesh material that are joined so that the structures or elements include at least one course in common (i.e., sharing a common yarn or common thread) and / or including fields that are substantially continuous between each part of the 116 mesh component. With this arrangement, an element of a unitary mesh construction piece is provided.
    [022] Although the mesh component portions 116 can be joined together after the knitting process, the mesh component 116 remains formed of unitary mesh construction, as it is formed as a single piece mesh element. In addition, the mesh component 116 remains formed of unitary mesh construction when other elements (for example, an embedded wire, a closing element, logos, trademarks, labels with care instructions and material information and other structural elements) are added after the knitting process.
    [023] FIGS. 4 to 6 illustrate examples of embodiments of the mesh component 116 by defining most of the upper 120 of the shoe article 100. As shown, the 116 mesh component of the upper 120 may include a base portion 124 or portion strobel or portion under the feet. In addition, the mesh component 116 may include one or more side portions 126 that extend from the base portion 124. The base portion 124 may be configured to be adjacent to the sole structure 110. For example, the portion of sole base 124 can connect directly or indirectly to sole structure 110 such that base portion 124 is over sole structure 110. In additional embodiments, one or more parts of base portion 124 (for example, a the periphery of the base portion 124) can connect to the sole structure 110, while the other parts remain separate or dissociated. In addition, the base portion 124 can be configured to extend under the user's foot. The side portion (s) 126 can extend from the base portion 1242 and can be configured to cover, at least partially, the user's foot. In addition, the base portion 124 and the side portion (s) 126 may cooperate to define a space 122 that receives the user's foot. Again, the base portion 124 and the side portion (s) 126 can be formed from a unitary mesh construction, as discussed above.
    [024] As shown in the illustrated embodiments, the side portions 126 of the mesh component 116 can include a heel portion 128, a side portion 130, a middle portion 132, a forefoot portion 134, and a tongue portion 136, each one of which is formed from the same unit mesh construction as the base portion 124. Thus, the mesh component 116 can accommodate and adapt close to the user's foot. In addition, due to this construction, the mesh component 116 can be formed relatively quickly to increase production efficiency.
    [025] In addition, as shown in FIG. 6 and as will be discussed in detail, the mesh component 116 can include one or more extensible yarns 158, which are incorporated into the unitary mesh construction of the mesh component 116. For example, the yarns 158 can be embedded within the strokes and / or columns of the 116 mesh component, as will be discussed. In addition, yarns 158 can be attached to the inside and / or outside of the surface of the 116 mesh component.
    [026] The wire (s) 158 may be arranged at the top to extend between the sides and / or under the user's foot. In addition, the wire (s) 158 can be operationally connected to a closing element 154, such as a shoelace 155. In this way, the tensioning of the shoelace 155 can, in turn, tension the 158 thread (s). As a result, the 158 thread (s) can provide a user's footrest for greater comfort and better fit.
    [027] The illustrated embodiments of the upper 120 and the shoe 100 are configured to be worn on a left foot of the user. However, it is noted that the shoe 100 can be configured for use with the right foot and can include features similar to the illustrated embodiments.
    [028] Footwear 100 can also be configured as a running shoe. However, footwear 100 can also be applied to a variety of other types of sports shoes, including baseball shoes, basketball shoes, cycling shoes, soccer shoes, sneakers, soccer shoes, training shoes, walking shoes and boots , for example. The concepts can also be applied to types of footwear that are generally considered non-athletic, including shoes, loafers, sandals and work boots. Therefore, the concepts described in relation to footwear 100 apply to a wide variety of types of footwear. Examples of Characteristics of Mesh Components
    [029] In the examples of embodiments, schematically illustrated in FIG. 13, the primary element of the knitted component 116 may be formed from at least one thread 1138 or another thread that is manipulated (for example, with a knitting machine) to form a plurality of interlocking loops that define a variety of courses and columns. Although line 1138 forms each of the courses and columns in this configuration, additional lines can form one or more courses and / or columns.
    [030] The properties that a given type of thread will transmit to an area of a knitted component depend, in part, on the materials that form the various filaments and fibers within the yarn. Cotton, for example, provides a soft touch, natural aesthetics, and biodegradability. Elastane and elastic polyester each provide substantial stretch and recovery; with elastic polyester the recycling capacity is also provided. Rayon provides high gloss 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.
    [031] Additional examples of an appropriate configuration for a portion of the 116 mesh component are shown in Figure 14. In this configuration, the 116 mesh component includes lines 1138 and another line 1139 (i.e., many wires). Lines 1138 and 1139 are covered and form, in a cooperative manner, a plurality of interconnected loops that define several horizontal courses and vertical columns. That is, lines 1138 and 1139 run parallel to each other. An advantage of this configuration is that the properties of each of the lines 1138 and 1139 can be present in this area of the 1130 mesh component. For example, the lines 1138 and 1139 can have different colors, with the color of the line 1138 being mainly present in a face of the various points on the mesh element 1131 and the color of the line 1139 being essentially present on the opposite face of the various points on the mesh element 1131. As another example, the line 1139 can be formed from a line that is softer and more comfortable for the foot than line 1138, with line 1138 being essentially present on the first surface 1136 and line 1139 being mainly present on the second surface 1137.
    [032] In addition, as shown in FIGS. 13 and 14, a yarn 1132 may be included in the unitary mesh construction of the 116 mesh component. The 1132 yarn may be an extensible yarn element that provides support for the 116 mesh component. In other words, the tension within the yarn 1132 may allow the mesh component 116 to resist deformation, distension, or otherwise provide support to the user's foot during runs, jumps, or other movements of the user's foot. In addition, it is noted that the extensible yarn 158 of FIG. 6 (mentioned above and described in detail below) can be included in the mesh component 116 similar to the yarns 1132 of FIGS. 13 and 14.
    [033] As will be discussed, yarn 1132 can be incorporated or embedded in the unit mesh construction of the 116 mesh component such that yarn 1132 can be included during the knitting process of the knitting machine. For example, yarn 1132 can be embedded within the unit mesh construction such that yarn 1132 extends along one of the courses, as shown in FIGS. 13 and 14 and / or the columns of the 116 mesh component. As shown in FIGS. 13 and 14, yarn 1132 can alternate between being located (a) behind the loops formed from lines 1138 and (b) in front of the loops formed from lines 1138. In effect, the built-in yarn 1132 weaves through the construction unit mesh of the 1131 mesh element.
    [034] The knitted component may also include one or more threads or threads that are formed from at least one of a thermoset polymeric material and natural fibers (for example, cotton, wool, silk). Other wires or threads can be formed from a thermoplastic polymeric material. In general, a thermoplastic polymeric material melts when heated and returns to a solid state when cooled. More particularly, the thermoplastic polymeric material transitions from a solid state to a softened or liquid state when subjected to sufficient heat, and then the thermoplastic polymeric material transitions from the softened or liquid state to a solid state when sufficiently cooled. As such, thermoplastic polymeric materials are often used to join two objects or elements together. In this case, the yarn can be used to adhere (a) a portion of the thread to another portion of the thread, (b) the threads and threads embedded in each other, or (c) another element (for example, logos, trademarks , and labels with instructions for use and material information) to the mesh component, for example. As such, the line can be considered as a fusible line as it can be used to fuse or otherwise join the mesh component portions together. In addition, the line can be considered as a non-fusible line since it is not formed from materials that are generally capable of melting or otherwise joining the mesh component portions together. That is, the line can be a non-fusible line, whereas another line (s) can be a fusible line. In some configurations of the mesh component, the line (i.e., the non-fusible line) can be substantially formed from a thermosetting polyester material and the line (i.e., the fusible line) can be at least partially formed from a thermoplastic polyester material.
    [035] The use of coated threads can give advantages to the mesh component. When the thread is heated and combined with the thread and the embedded wire, this process can have the effect of hardening or stiffening the mesh component structure. In addition, joining (a) a portion of thread to another portion of thread or (b) threads and thread embedded to each other has the effect of fixing or blocking the relative positions of the thread and thread embedded, thereby conferring , resistance to distension and stiffness. That is, the line portions cannot slide in relation to each other when combined with the lines, thus avoiding permanent deformation or distension of the mesh element due to the relative movement of the mesh structure. Another advantage concerns limiting dissolution / unraveling if a portion of the mesh component is damaged or one of the lines is broken. Therefore, mesh component areas can benefit from using both combinable and non-combinable lines within the mesh element.
    [036] In addition, it is noted that the mesh component may have different zones, which collectively form the unitary mesh construction. For example, the mesh component may include a combination of at least two of the following elements: a straight mesh zone, a tubular mesh zone, a 1x1 mesh zone, a 2x2 mesh zone, a mesh zone with 3x2 mesh, mesh zone with simulated 1x1 mesh, mesh zone with simulated 2x2 mesh, hybrid 2x2 mesh zone, complete measurement zone, mesh zone with% measurement, and the like. Therefore, the mesh component 116 and the upper part 120 can be constructed in accordance with the teachings of US Patent Publication No. 2012/0233882, published on September 20, 2012, and which is incorporated here, by reference, into its entirety. Embodiments of the Upper Part and the Mesh Component
    [037] Several embodiments of the upper part 120 and the mesh component 116 will now be discussed in more detail. As shown, the upper part 120 can define a longitudinal direction 125, 127 a transverse direction, and a vertical direction 129, which will be used to reference the different characteristics of the upper part 120 in the discussion below.
    [038] As mentioned above, the mesh component 116 of the upper part 120 may include a base portion 124, which is configured to be placed under the user's foot. An outline of the user's foot is shown in FIG. 6, such that the base portion 124 is at least generally defined in relation to the user's foot. Thus, the base portion 124 may extend continuously under one or more parts of the heel, sole, toes, arch, and / or other lower surfaces of the user's foot. In additional embodiments, the base portion 124 may include openings so as to extend partially or discontinuously under the user's foot.
    [039] The mesh component 116 may also include several side portions 126 that extend peripherally from the base portion 124. The side portions 126 can be configured to cover and be in contact with at least a portion of the user's foot. In the illustrated embodiments, the side portions 126 of the mesh component 116 can substantially encompass the base portion 124. Furthermore, it will be understood that the base portion 124 and the side portions 126 can together define the inner surface 121 of the mesh component 116 as well as the outer surface 123 of the mesh component 116.
    [040] For example, the side portions 126 may include a heel portion 128, which is arranged over one end of the base portion 124. The heel portion 128 may also extend upwardly from the base portion 124 in the vertical direction 129, as shown in FIG. 4. The heel portion 128 can be configured to cover an area of the user's heel and / or ankle.
    [041] The side portions 126 of the mesh component 116 can also include a side portion 130, which is arranged forwardly relative to the heel portion 128, and which can extend upwardly from a side face of the portion base plate 124, as shown in FIG. 4. Lateral portion 130 can be configured to cover and be in contact with a lateral area of the user's foot.
    [042] In addition, the side portions 126 of the knitted component 116 may include a middle portion 132, which is disposed on an opposite side of the base portion 124, in relation to the side portion 130, and in front of the heel portion 128 The middle portion 132 may extend further upward in the vertical direction 129 from the base portion 124, as shown in FIG. 4. The middle portion 132 can be arranged on the opposite side of the base portion 124 in the transverse direction 127. The middle portion 132 can be configured to cover and be in contact with a middle area or the user's forefoot.
    [043] The heel portion 128, the side portion 130, and the middle portion 132 can collectively define a horseshoe-shaped collar 133 from the top 120. The collar 133 can provide access to the interior and exterior of space 122 of the upper part 120. In addition, a side edge 135 of the side portion 130 and a middle edge 137 of the middle portion 132 can collectively define a throat 131 of the upper part 120. The throat 131 can extend substantially parallel to the direction longitudinal 125, or the throat 131 can be arranged at an angle to the longitudinal direction 125. In addition, although the throat 131 is substantially centered on the base portion 124 in the embodiments of FIG. 4, the throat 131 can be arranged on one side with respect to the base portion 124 in the transverse direction 127. As will be discussed, the width of the throat 131 can vary selectively through the closing element 154 in order to move the lateral edges and average 135, 137 towards and away from each other. As a result, shoes 100 can be selectively tightened on the user's foot and loosened on the user's foot.
    [044] In addition, the side portions 126 of the mesh component 116 may include a forefoot portion 134. The forefoot portion 134 may be arranged at an opposite end of the base portion 124 with respect to the heel portion 128 and at the front of the lateral and middle portions 130, 132 in the longitudinal direction 125, as shown in FIG. 1. In addition, the forefoot portion 134 can be integrally connected to both the side portion 130 and the middle portion 132 and the forefoot portion 134 can be separated from the other. In the shown embodiments, for example, the forefoot portion 134 is integrally connected to the side portion 130 and is spaced from the middle portion 132. Consequently, when the upper portion 120 is in a disassembled state, as shown in FIG. 4, a gap 139 can be defined between the forefoot portion 134 and the middle portion 132.
    [045] In addition, the side portions 126 of the mesh component 116 may include a tongue portion 136. As shown in FIG. 4, the tongue portion 136 may include a curved region 143 and a longitudinal region 145. When the upper part 120 is disassembled, as shown in FIG. 4, the tongue portion 136 may generally extend forward from the base portion 124, and the curved region 143 may be arranged within the gap 139 between the middle portions and forefoot. The curved region 143 can also curve in such a way that the longitudinal region 145 generally extends backwards and at an angle 143 relative to the middle portion 132, as shown in FIG. 4. The curvature of the curved region 143 can be achieved by means of the mesh strokes that radiate substantially from a common area 151, as shown in FIG. 5. Common area 151 may be an imaginary point that is spaced from the periphery of curved region 143, between tongue portion 136 and middle portion 132, as shown, or common area 151 may be arranged elsewhere. In addition, when the upper part 120 is mounted, the curved region 143 can roll upwards, at least partially, to fill the gap 139, and the longitudinal region 145 of the tongue portion 136 can be arranged inside the throat 131 of the part upper in order to cover the entire foot of the user between the side portion 130 and the middle portion 132. In addition, when the upper part 120 is mounted, the longitudinal region 145 of the tongue portion 136 can be separated and dissociated from the side portions and / or average 130, 132, as shown in FIG. 3.
    [046] As shown in FIGS. 4, 5 and 6, the base portion 124 and the heel portion 128 can define a heel cavity 148 that is configured to receive a heel from the user's foot (see FIG. 6). The heel cavity 148 may have an inner and / or outer surface with three curvature dimensions. In addition, the heel cavity 148 may have a convex outer surface. Thus, as the heel portion 128 extends in the vertical direction 129, from the base portion 124, the heel portion 128 may curve slightly forward in the longitudinal direction 125. In addition, as the heel portion 128 extends in the transverse direction 127, both sides of the heel portion 128 can bend forward in the longitudinal direction 125 to join the side and middle portions 130, 132. Therefore, the heel cavity 148 can adapt and correspond approximately to the shape of the user's heel and ankle.
    [047] Furthermore, as shown in FIGS. 4, 5 and 6, the base portion 124 and the forefoot portion 134 can define a forefoot cavity 150 that is configured to receive the toes and other regions of the user's forefoot (see FIG. 6). The forefoot cavity 150 may have an inner and / or outer surface with three curvature dimensions. In addition, the forefoot cavity 150 may have a convex outer surface. Thus, as the forefoot portion 134 extends in the vertical direction 129 from the base portion 124, the forefoot portion 134 can bend backwards in the longitudinal direction 125. In addition, as the portion for forefoot 134 extends in the transverse direction 127, the forefoot portion 134 can bend backwards in the longitudinal direction 125 to join the lateral portion 130.
    [048] The three-dimensional curvature of the heel cavity 148 and / or the forefoot cavity 150 can be formed due to the unit mesh construction of the 116 mesh component. For example, as shown in FIG. 8, the heel portion 128 may include at least two conical areas 170, 171. The conical areas 170, 171 may have boundaries 173 that taper in the generally transverse direction 127, as indicated by the dashed lines. Each of the conical areas 170, 171 has a plurality of courses, or row of points; however, successive strokes may have different lengths to provide the tapered shape of the 173 boundaries. Thus, the tapered areas 170, 171 may have an eye shape, a double-pointed oval shape, a biconvex shape, or a increasing shape.
    [049] In addition, boundary 173 of conical area 170 is joined to boundary 173 of conical area 171 in the single mesh construction to provide the 116 mesh component with dimensional curvature. This can produce a visually evident distortion along the boundary 173. The distortion may be a brand named as fully molded that extends along the boundary 173 on the mesh component 116.
    [050] In the embodiments of FIG. 8, there are a plurality of conical areas that are joined along their respective boundaries in such a way that the conical areas extend from the collar 133 of the base portion 124 and most of the heel portion 128 includes these conical areas. Consequently, most of the heel portion 128 may have three-dimensional curvature. However, it is noted that the mesh component 116 can include any number of conical areas 170, 171 in any portion of the mesh component 116 in order to provide a three-dimensional curvature to the mesh component 116. In addition, the conical areas 170 , 171 can be oriented in any suitable direction on the 116 mesh component. For example, the forefoot portion 134 may include similarly conical areas; However, these conical areas can taper in the vertical direction 129 in examples of embodiment.
    [051] The curved region 143 of the tongue portion 136 may also include a plurality of conical areas that provide curvature to the curved region 143. For example, the curved region 143 may include conical areas 193, 195 that are woven together integrally and joined along the 197 boundaries. This can produce a visually evident distortion along the joined 197 boundaries. The distortion can be termed as a fully molded mark that extends along the joined boundaries 197 on the 116 mesh component. mentioned above, courses within the curved region 143 can radiate from the common area 151 to provide two-dimensional curvature.
    [052] In addition, in some embodiments, the forefoot portion 134 may include a plurality of openings 152 that are arranged to assist in increasing the curvature of the forefoot portion 134. In the illustrated embodiments, the plurality of openings 152 may include one or more lines of through holes. Since the openings 152 reduce the amount of mesh material in those areas of the forefoot portion 134, the forefoot portion 134 can easily bend backward toward the heel portion 128.
    [053] The mesh component 116 may additionally include at least two edge portions 140, 142 which are configured to be joined together when the upper part 120 is assembled. It is noted that the first edge portion 140 can be a first longitudinal section of the larger peripheral edge 199 of the mesh component 116 shown in FIGS. 5 and 6. It should also be noted that the second edge portion 142 can be a second longitudinal section of peripheral edge 199. Edge portions 140, 142 can be defined at any suitable location along peripheral edge 199 and / or in anywhere on the 116 mesh component. As shown in FIGS. 5 and 6, the first edge portion 140 may extend along the curved region 143 of the tongue portion 136 and may also extend, partially, through the base portion 124 in the transverse direction 127, adjacent to the forefoot portion 134. The second edge portion 142 may curve along the forefoot portion 134, generally in the transverse direction 127 and may extend downwardly in the vertical direction 129 along the forefoot portion 134, in order to partially define the span 139. The first edge 140 and the second edge 142 can also meet at a notch / cut 141 defined within the base portion 124, as shown in FIG. 4.
    [054] As mentioned above, the shoe 100 may further include a closing element 154, which is illustrated in FIG. 1. The closing element 154 can selectively secure the upper part 120 to the user's foot and selectively release the upper part 120 of the user's foot.
    [055] As shown in FIG. 1, the closing element 154 can be a shoelace 155. As such, the side portion 130 can include one or more side closing openings 156, such as through holes that are arranged in a line extending along the side edge 135. The middle portion 132 may include similar medium closing openings 157 that are arranged in a line extending along the middle edge 137. The openings 156, 157 can receive the lace 155 so that the lace 155 can intersect , in a zigzag pattern, and alternate between the lateral and middle portions 130, 132.
    [056] It is noted that the openings 156, 157 can be configured differently from the through holes shown in FIG. 1. For example, openings 156, 157 can be defined by hoops, eyelets, hooks, and other appropriate features that are configured to receive a closing element, and that are integrated into both the 116 mesh and connected components, removably , to the 116 mesh component.
    [057] In addition, it is noted that the closing element 154 may include a different structure from the shoelace 155, without departing from the scope of this disclosure. For example, the closing element 154 can be a strap, a buckle, velcro, or other suitable closing element.
    [058] Furthermore, as shown in FIG. 6, the upper part 120 can include at least one extensible yarn 158 which is coupled to the base portion 124 and / or to the side portions 126. The extendable yarn 158 can be coupled to any part of the base portion 124 and / or from the side portion 126. In addition, the extensible yarn 158 can be coupled to the base portion 124 and / or to the side portion 126 in any suitable manner. For example, the extensible yarn 158 may be embedded within courses and / or columns of the unitary mesh of the base portion 124 and side portions 126, as will be discussed. Thus, wire 153 may correspond to wire 1132 described above and shown in FIGS. 13 and 14. Extendable wire 158 can also be adhered, fixed, perforated, or otherwise coupled to the interior or exterior surfaces 121, 123 of the base portion 124 and / or the side portion 126.
    [059] Yarn 158, 116 mesh component and top 120 may incorporate the teachings of one or more of US Patent Application Serial Number 12 / 338,726 owned by Dua et al., Entitled "Article of Footwear Having An Upper Incorporating A Knitted Component ", filed on December 18, 2008 and published as US Patent Application under Publication Number 2010/0154256, on June 24, 2010, and US Patent Application Serial Number 13 / 048,514 by Huffa et al ., entitled “Article of Footwear Incorporating a Knitted Component”, filed on March 15, 2011 and published as US Patent Application under Publication Number 2012/0233882, on September 20, 2012, both applications are incorporated here, by reference, in its entirety (collectively referred to here as the "embedded wire cases").
    [060] The yarn 158 can be an elongated and flexible element. In addition, yarn 158 may include at least one thread, cable, yarn / wire, twine, cord, filaments, fibers, yarn, rope, and the like. In addition, yarn 158 can be formed from rayon, nylon, polyester, polyacrylic, silk, cotton, carbon, glass, aramids (e.g. para-aramid fibers and meta-aramid fibers), ultra high polyethylene molecular weight, liquid crystal polymer, copper, aluminum, steel, or other suitable material. An individual filament used in yarn 158 can be formed from a single material (i.e., a single component filament) or from several materials (i.e., a two-component filament). Likewise, different filaments can be formed from different materials. As an example, the threads used as yarn 158 may include filaments that are each formed from a common material, may include filaments that are each formed from two or more different materials, or may include filaments that are formed, each, from two or more different materials. Similar concepts apply equally to wires, cables, cords, etc. The thickness (diameter) of the wire 158 can be within a range of about 0.03 millimeters to 5 millimeters, for example. In addition, wire 158 may have a substantially circular cross section, an oval cross section, or a cross section of any other suitable shape.
    [061] As an example, yarn 158 can be formed from a 6.6 nylon nylon with a tensile strength of 3.1 kg and a weight of 0.045 grams / meter (45 tex). Yarn 158 can also be formed from 6.6 nylon with a tensile strength of 6.2 kg and a weight of 0.045 grams / meter (45 tex). As another example, yarn 158 may have an outer sheath that protects and covers an inner core.
    [062] In some embodiments, the wire 158 may have a fixed length (for example, it may be non-extensible). In addition, in some embodiments, the yarn 158 may be elastically extensible.
    [063] In addition, in some embodiments, yarn 158 may include a thermoplastic material that is configured to adhere, bond, or melt to a base portion 124 and / or the side portions 126 of the upper part 120. For example, the Selective application of heat can cause the materials in the yarn 158 to combine with the materials of the base portion 124 and / or the side portions 126. The yarn 158 can thus be included in accordance with the teachings of US Patent Publication No. 2012/0233882, published on September 20, 2012, and which is incorporated herein, by reference, in its entirety.
    [064] As shown in the embodiments of FIG. 6, the upper part 120 may include a single thread 158 that extends continuously between the middle portion 132, the base portion 124, and the side portion 130. In addition, the thread 158 may include one or more loops 159, 160. The turns 159, 160 can be turns of one hundred and eighty degrees or more. Specifically, yarn 158 can include a plurality of side turns 159 that are arranged in a row along side edge 135, and yarn 158 can include a plurality of middle turns that are arranged in a row along middle edge 137. The yarn 158 can also extend linearly between the pairs of loops 159, 160. In addition, the yarn 158 can include a first end end 164, which is disposed adjacent to the heel portion 128, and the yarn 158 can include a second terminal end 166, which is disposed adjacent to the forefoot portion 134. The wire 158 can also extend alternately and in a zigzag pattern between the lateral and middle portions 130, 132.
    [065] In addition, as shown in FIGS. 6 and 7, the mesh component 116 can define a passage 162 between the inner surface 121 and the outer surface 123. The passage 162 can be defined in any suitable form. For example, in embodiments where the yarn 158 is embedded within the mesh component 116, the passage 162 can be defined by means of one or more strokes or columns of the mesh component 116. In addition, in some embodiments, the surface inner 121 can be defined by a layer of mesh material and outer surface 123 can be defined by a separate layer of mesh material, and a plurality of yarns, filaments or monofilaments can extend and provide the spacing between these layers (e.g. , the so-called "mesh spacer material"). In these embodiments, the passage 162 can be defined between the layers of mesh material and between the plurality of spacer threads. In additional embodiments, the inner surface 121 and the outer surface 123 can be interlocking stitched surfaces, and the passage 162 can be defined between these surfaces.
    [066] Passage 162 may extend through any portion of the upper portion 120. For example, as indicated by the dashed lines in FIG. 6, the upper part 120 can define a plurality of passages 162, and each pass 162 can extend continuously between the side portion 130, the base portion 124, and the middle portion 132. In the embodiments shown, each passage 162 extends partially through the side portion 130 (lateral passage), partially through the base portion 124 (passage of the base portion), and partially through the middle portion 132 (middle passage), such that the passage 162 is continuous between the side portion 130, base portion 124, and middle portion 132. However, it is noted that one or more passages 162 can be located and isolated in any portion of the upper portion 120.
    [067] As shown in FIG. 7, the wire 158 can be received and can extend longitudinally within one or more of the passages 162 so as to extend between the side portion 130, the base portion 124, and the middle portion 132. Likewise, the loops 159, 160 of wire 158 can be exposed from passages 162.
    [068] The side loops 159 can extend, at least partially, around the respective of the side closing openings 156, and the middle loops 160 can extend, at least partially, around the respective of the opening slits. closing averages 157. In addition, as shown in FIG. 1, the shoelace 155 can be received inside the respective pairs of side closing openings 156 and side turns 159, and the shoelace 155 can also be received inside the respective pairs of average closing openings 157 and the average turns 160. Said otherwise, each pairing of the side loops 159 and the side closing aperture 156 can cooperatively receive and maintain the shoelace 155, and each pairing of the middle loop 160 and medium closing aperture 157 can also receive and maintain the shoelace. 155.
    [069] In some embodiments, the wire 158 can be received freely and movably within the respective passages 162. For example, the wire 158 can slide longitudinally through the passages 162. Thus, as shown in FIG. 9, loops 159, 160 can be pulled closer to the respective closing aperture 156, 157. In additional embodiments, the first and / or second terminal end 164, 166 of wire 158 can be fixed (e.g., combined) to the base portion 124, while the remaining portions of the yarn 158 may remain movable with respect to the base, side, and middle portions 124, 130, 132. In other additional embodiments, portions of the yarn 158 between the end ends 164, 166 may combined or otherwise attached to the base, side, and middle portions 124, 130, 132.
    [070] Therefore, the tensioning of the shoelace 155 can, in turn, increase the tension in the yarn 158. For example, as shown in FIG. 10, when the shoelace 155 is loose and in the open (not secured) position, the tension in the yarn 158 can be relatively low, thereby allowing the upper part 120 to fit freely on the user's foot. However, when shoelace 155 is pulled and tensioned as indicated by arrows 174, 175, shoelace 155 can pull loops 159, 160 to increase tension on yarn 158. As a result, extensible yarn 158 can pull the top and adapt the upper part 120 close to the user's foot, as indicated by arrows 176, 177, 178, 179 in FIG. 11.
    [071] It should be noted that in the embodiments shown in FIGS. 10 and 11, wire 158 can provide support for various areas at the bottom of the user's foot. For example, wire 158 can be arranged in a region of arch 164, which is configured to be placed under the arch of the user's foot. Thus, the yarn 158 within the arc region 164 can maintain the user's arc, especially when the yarn 158 is subjected to tension by the shoelace 155.
    [072] It should be noted that, in the illustrated embodiments, the upper part 120 may include only a continuous thread 158 to provide such a footrest. Therefore, the part count of the upper part 120 can be relatively low, and the upper part 120 can be constructed in an efficient manner. Footwear Assembly
    [073] The assembly of the shoes 100, the mesh component 116 and the upper 120 will now be analyzed according to the examples of embodiments. For the sake of clarity, it must be assumed that the knitted component 116 and the yarn 158 were formed in the disassembled state shown in FIGS. 5 and 6.
    [074] To begin the examples of top assembly assembly embodiments 120, the side and middle portions 130, 132 can be moved (folded) higher than the position shown in FIG. 4. Then, the tongue portion 136 can be rolled upwardly so that the curved region 143 substantially fills the gap 139 and the longitudinal region 145 substantially fills the throat 131. As such, the first and second edge portions 140, 142 can be arranged directly adjacent to each other. Then, the first and second edge portions 140, 142 can be joined at a seam 144.
    [075] The first and second edge portions 140, 142 can be joined at the seam 144 in any suitable manner. For example, the first and second edge portions 140, 142 can be joined by sewing, adhesives, tape, glue, welding, with fasteners, or other suitable fastening devices.
    [076] In some embodiments, the seam 144 can be formed by sewing the edge portions 140, 142 together with the seam 146, as shown in FIGS. 1-3. As mentioned above, the upper part 120 can be a mesh element with a plurality of points; however, it will be noted that the seam 146 can be independent of the stitches of the 116 mesh component. In other words, the seam 146 can be formed using one or more wires, threads, cables or other wires that are attached after the component in knit 116 have been knitted. The seam 146 may also be a zigzag stitch or other suitable stitch. In addition, edge portions 140, 142 can abut seam 144. For example, edge portions 140, 142 can form a butt joint, or edge portions 140, 142 can be partially overlapping to form seam 144. In addition, edge portions 140, 142 can be slightly separated at seam 144 by a strand of adhesive or other material between edge portions 140, 142 at seam 144.
    [077] In addition, the seam 144 can extend to any suitable part of the mesh component 116. For example, in the embodiments of FIG. 3, seam 144 can include a first end end 147 arranged in the base portion 124, adjacent to the forefoot portion 134. Seam 144 can also include a second end end 149, at the junction of side edge 135, of the forefoot portion 134 , and the tongue portion 136. In addition, the seam 144 may extend continuously between the first and second end ends 147, 149, in some embodiments. For example, seam 144 may include a first portion 181 that extends along the base portion 124, generally in the transverse direction 127 towards the middle portion 132 from the first terminal end 147. Seam 144 may also include a second portion 183 which generally extends in the vertical direction 129 between the middle portion 132 and adjacent to the forefoot portion 134. The seam 144 may further include a third portion 185 which generally extends transversely towards the lateral portion 130 and which curves back towards the second terminal end 149. Thus, the seam 144 can extend continuously between the ends 147, 149 so as to extend under the user's foot, around a medium area of the user's forefoot, to an area above the user's forefoot.
    [078] In addition, there may be any number of seams 144 of the mesh component 116. As shown in the embodiments of FIG. 3, for example, there may be only one solitary seam 144 necessary to give the mesh component 116 of the upper part 120 the three-dimensional shape shown in FIGS. 1-3. This can facilitate fabrication and reduce the time for assembly of the upper part 120.
    [079] In addition, seam 144 can be spaced from heel portion 128 so that heel portion 128 is continuous / seamless. Thus, even if the heel portion 128 moves over the user's heel, it is unlikely that the heel portion 128, relatively smooth and continuous, will rub the user's heel and provide discomfort to the user.
    [080] Subsequently, the shoelace 155 can be placed through the side and middle openings 156, 157 and the side and middle turns 159, 160, as discussed above. Then, the sole structure 110 can be attached to the upper part 120. Specifically, the midsole 112 can be attached to the outer surface 123 of the base portion 124, and the outer sole 114 can be attached to the midsole 112. In additional embodiments, an additional insole can be inserted over and / or attached to the inner surface 121 of the base portion 124. Additional Embodiments of the Mesh and Upper Component
    [081] Additional embodiments of the mesh component 116 and the upper part 220 are illustrated in FIG. 12. The mesh component 116 and the upper part 220 may be substantially similar to the mesh component 116 and the upper part 120 described above, except as discussed.
    [082] The upper part 220 may include a thread 258 that alternately extends through the middle portion 232, the base portion 224, and the side portion 230, similar to the embodiments discussed above. The wire 258 can also extend through one or more passages 262. However, the passages 262 can be defined in the middle portion 132 and the side portion 130, and the passages 262 can be moved away from the base portion 224.
    [083] Therefore, the longitudinal portions of the wire 258, which extend through the base portion 224, can be exposed from the passages 262. In addition, these parts of the wire 258 can be separated and dissociated from the portion of the base 224. Thus, in some embodiments, these portions of the yarn 258 may be free to be connected directly to the sole structure 110.
    [084] In addition, as shown in FIG. 12, in some embodiments, the passages 262 can be in V-shape, such that the loops of the wire 258 are incorporated and closed within the passages 262, in contrast to the exposed loops 159, 160, shown in FIGS. 1-6.
    [085] Other embodiments of the mesh component 316 and the upper part 320 are shown in FIGS. 24 and 25. The mesh component 316 and the upper part 320 may be substantially similar to the mesh component 116 and the upper part 120 described above, except as discussed.
    [086] As shown in FIG. 24, the mesh component 316 may include a base portion 324 and a side portion 326 extending from base portion 324. In some embodiments, side portion 326 may substantially encompass base portion 324. For example, For example, side portion 326 can define heel portion 328, side portion 330, middle portion 332 and forefoot portion 334.
    [087] Furthermore, the upper part 320 may include a plurality of parts 329, 331, each of which individually has a unitary mesh construction, and the parts 329, 331 can be joined to one or more seams 333, 335 , 337, as shown in FIG. 24. Thus, parties 329, 331 can cooperate to define a space for receiving a foot. It is noted that the upper part 320 may include any appropriate number of parts 329, 331 and any number of seams 333, 335, 337.
    [088] Each part 329, 331 can be formed from materials that have unitary mesh construction. For example, as shown in FIG. 25, parts 329, 331 can be formed from a first layer 381 and a second layer 383 of mesh sheet material, and a plurality of spacer threads 385 can extend transversely between layers 381, 383. The threads spacers 385 can be made from monofilaments or other suitable materials and can extend substantially perpendicularly between layers 381, 383. Spacing threads 385 can also extend at an angle other than ninety degrees between layers 381 , 383, 385 and the yarns may be zigzagged between layers 381, 383 in some embodiments. Spacer wires 385 can couple and provide spacing between layers 381, 383. In this way, parts 329, 331 can be manufactured from so-called "mesh spacer materials", and can include materials disclosed in the Order for US Patent No. 12 / 388,726, filed on December 18, 2008, published on June 24, 2012, Publication No. 2010-0154256, which are incorporated herein by reference in their entirety.
    [089] Furthermore, as shown in FIG. 25, the first layer 381 can define the outer surface 323 of the upper part 320. In addition, the second layer 383 can define the inner surface 321 of the upper part 320.
    [090] Furthermore, one or both layers 381, 383 can include one or more openings 397. There can be any number of openings 397, openings 397 can have any shape, and openings 397 can be arranged in any suitable manner. For example, as shown in the illustrated embodiments, the first layer 381 can include a plurality of rounded openings 397 which are arranged in rows extending between the middle portion 332 and the side portion 330 and between the base portion 324 in the transverse direction 327 In contrast, the second layer 383 can be substantially continuous and without openings 397.
    [091] The first part 329 can define the lateral portion 330 and lateral areas of the heel portion 328 and forefoot portion 334 of the upper part 320. In contrast, the second part 331 can define the middle portion 332 and the medial areas of the portion for heel 328 and forefoot portion 334.
    [092] Parts 329, 331 can be joined at seams 333, 335, 337, so that parts 329, 331 cooperate to define the standing reception space of the top 320. Seams 333, 335, 337 can be defined in any suitable location at the top 320.
    [093] More specifically, in the embodiments shown in FIG. 24, a seam 333 is substantially centered on the base portion 324 and extends in the longitudinal direction 325. In addition, a forefoot seam 335 extends under the forefoot portion 334 and generally extends in the transverse direction 327 On the other hand, a heel seam 337 extends under the heel portion 328 and generally extends in the transverse direction 327.
    [094] The seams 333, 335, 337 can be fixed in any suitable way, such as rope, thread, or other threads, or adhesives, with fasteners, tapes, or other suitable fastening instruments. For example, a rope, threads, cables or other types of yarn can be used to fix the seams 333, 335, 337. It is noted that these threads that fix the seams 333, 335, 337 can be independent of the unitary mesh construction parts 329, 331.
    [095] In addition, one or more passages 362 can be defined longitudinally through the upper part 320, as shown in FIG. 24, and radially between the inner and outer surfaces 321, 323, as shown in FIG. 25. Thus, passages 362 can be defined between the plurality of spacer wires 385, as shown in FIG. 25.
    [096] Passages 362 can extend through any portion of the upper portion 320. For example, passages 362 can extend, at least partially, through base portion 324. In the illustrated embodiment examples, passages 362 can extend continuously between the middle portion 332 and the base portion 324 and / or the passages 362 extend continuously between the side portion 330 and the base portion 324. In addition, in some embodiments, the passages 362, in the first part 329, can be substantially aligned longitudinally with the passages 362 in the second part 331.
    [097] As shown in FIGS. 24 and 25, the extendable strands 358 can extend through the respective passages 362. The extendable strands 358 can extend at any suitable location in the upper part 320. For example, the strands 358 can extend continuously between the portion side 330, base portion 324, and middle portion 322. In additional embodiments, yarns 358 can be located in base portion 324. Yarns 358 can also be conducted through mesh member 316 in other ways as well.
    [098] As shown in FIGS. 24 and 25, the longitudinal portions of the wires 358 can be exposed externally, due to the openings 397. This can provide access to the wires 358, in case the wires need to be handled. In addition, yarns 358 can be a contrasting color of layer 381 to increase aesthetic appeal. In addition, different 358 yarns can have different colors from each other to increase the aesthetic appeal.
    [099] Thus, like the embodiments described above and shown in FIGS. 1-6, the extensible strands 358 may increase in tension when the lace or other closure element is tightened. This, in turn, can bring the upper part 320 close to the foot and adapt the upper part 320 to the shape of the foot for greater comfort. In addition, tension on the 358 wires can provide additional foot support. Examples of Knitting Processes for Component Formation in Mesh and Upper
    [0100] The 116 mesh component can be knitted in any suitable direction. For example, the mesh component 116 can be formed from the heel portion 128, the collar 133, and the mesh component 116 can be formed so as to grow, generally, in the longitudinal direction 125 towards the forefoot portion 134 The forefoot cavity 150 can be formed before the tongue portion 136. Then, the tongue portion 136 can be formed subsequently. In addition, the extensible yarn 158 can be embedded during this knitting process. It is observed that the three-dimensionally curved cavities and the two dimensionally curved portions of the mesh component 116 (such as the heel cavity 148, the forefoot cavity 150, the curved region 143 and / or other areas) can be formed separately during the knitting process. Specifically, stitches at boundaries 173, 197 can be made by the respective needles as subsequent strokes of stitches are added, and stitches made at boundaries 173, 197 can be knitted to the respective stitches using boundaries 173, 197. In addition, this process can be completed on any suitable machine, such as a straight knitting machine.
    [0101] Referring now to FIGS. 15-23, examples of automated knitting processes to form the 116 mesh component with the yarn 158 will be discussed. For the purposes of discussion, the straight knitting processes and straight looms will be discussed, however, the knitted component 116 and the yarn 158 can be formed in another way, without departing from the scope of this disclosure. Thus, the knitted component 116 and yarn 158 can be formed in accordance with the teachings of US Patent Publication No. 2012/023388, published on September 20, 2012, which is incorporated herein by reference in its entirety.
    [0102] Referring to Figure 15, a portion of the knitting machine 1200, which includes several needles 1202, rails 1203, standard feeders 1204, and feeders in combination 1220, is shown. While the combination feeders 1220 are attached to the front side of the rail 1203, the standard feeder 1204 is attached to the rear of the rail 1203. Line 1206 passes through the combination feeder 1220, and one end of the line 1206 extends to outside the dispensing tip 1246. Although line 1206 is shown, any other wire (for example, filaments, wires, ropes, straps, cables, chains or lines) can pass through the feeder in combination 1220. Another line 1211 passes through the feeder pattern 1204 and forms a portion of a mesh component 1260, and thread loops 1211, which form a stroke of the upper part in mesh component 1260, are made by hooks located at the ends of the needles 1202.
    [0103] The knitting process discussed here refers to the formation of the 1260 mesh component or 1260 mesh component portion. Thus, the 1260 mesh component portion may correspond to the base portion 124, the heel portion 128, the side portion 130, the middle portion 132, the forefoot portion 134, and / or the tongue portion 136, discussed above with reference to FIGS. 1-6. For the purposes of discussion, only a relatively small section of the 1260 mesh component is shown in the figures to allow the mesh structure to be illustrated. In addition, the size or proportions of the various elements of the knitting machine 1200 and the knitted component 1260 can be enlarged to better illustrate the knitting process.
    [0104] Referring now to FIG. 16, the standard feeder 1204 moves along rail 1203 and a new stroke is formed in the mesh component 1260 from line 1211. More particularly, needles 1202 pull sections of thread 1211 through the handles of the previous stroke, thereby forming mode, the new course. Thus, strokes can be added to the 1260 mesh component by moving the standard feeder 1204 next to needles 1202, thus allowing needles 1202 to handle line 1211 and form additional handles from line 1211.
    [0105] Continuing with the knitting process, the feeder arm 1240 now moves from the retracted position to the extended position, as shown in FIG. 17. In the extended position, the feeder arm 1240 extends downwardly from the conveyor 1230 to position the dispensing tip 1246 at a location that is at (a) the center between the needles 1202, (b) below the intersection of the beds of needles.
    [0106] Referring now to FIG. 18, the combination feeder 1220 moves along rail 1203 and line 1206 is placed between the handles of the 1260 mesh component. That is, line 1206 is located in front of some handles and behind other handles in a alternating pattern. In addition, line 1206 is placed in front of the handles, which are being made by needles 1202, from a bed of needles 1201, and line 1206 is placed behind the handles, which are being made by needles 1202, from of a bed of needles. It is observed that the feeding arm 1240 remains in the extended position, in order to embed the line 1206 in the area below the intersection of the needle beds. This effectively places line 1206 within the newly formed stroke by standard feeder 1204 in FIG. 16.
    [0107] In order to complete the incorporation (inlay) of line 1206 in the 1260 mesh component, the pattern feeder 1204 moves along rail 1203 to form a new course from line 1211, as shown in FIG. 19. When forming the new course, thread 1206 is effectively knitted inside or otherwise integrated into the structure of the 1260 mesh component. In this phase, the feed arm 1240 can also move from the extended to the retracted position.
    [0108] FIGS. 18 and 19 show separate movements of feeders 1204 and 1220 along rail 1203. That is, FIG. 18 shows a first movement of the combined feeder 1220 along the rail 1203, and FIG. 19 shows a second and subsequent movement of the standard feeder 1204 along rail 1203. In many knitting processes, feeders 1204 and 1220 can effectively move simultaneously to embed line 1206 and form a new course from line 1211. The combination feeder 1220, however, advances or moves in front of the standard feeder 1204 in order to position line 1206 prior to the formation of the new course from line 1211.
    [0109] The general knitting process, described in the discussion above, provides an example of the way in which yarn 158 of FIGS. 1-6 can be located in the base portion 124, in the side portion 130, and / or in the middle portion 132 of the upper part 120. More particularly, due to the alternating action of the feeder arm 1240, the wire 158 can be located within a previously formed course before the formation of a new course.
    [0110] Continuing with the knitting process, the feeder arm 1240 now moves from the retracted position to the extended position, as shown in FIG. 20. The combined feeder 1220 then moves along the rail 1203 and line 1206 is placed between the handles of the 1260 mesh component, as shown in FIG. 21. This effectively places line 1206 within the stroke formed by standard feeder 1204 in FIG. 19. In order to complete the incorporation of line 1206 into the mesh component 1260, the standard feeder 1204 moves along rail 1203 to form a new course from line 1211, as shown in FIG. 22. When forming the new course, thread 1206 is effectively knitted inside or otherwise integrated into the structure of the 1260 mesh component. In this phase, the feed arm 1240 can also move from the extended to the retracted position.
    [0111] Referring to FIG. 22, line 1206 forms a loop 1214 between the two flush sections. In the discussion of loops 159, 160 of FIGS. 1-6, it has been found that the yarn 158 that leaves passage 162 and then enters another passage 162 thus forms loops 159, 160. Loop 1214 can be formed in a similar manner. That is, loop 1214 can be formed where line 1206 exits the mesh structure of the 1260 mesh component and then re-enters the mesh structure.
    [0112] With reference to FIG. 23, the combined feeder 1220 moves along the rail 1203 while in the stowed position and forms a 1260 mesh component course while in the stowed position. Therefore, by moving the feeder arm 1240 between the retracted position and the extended position, the combined feeder 1220 can provide thread 1206 for knitting, puckering, oscillation, and embedding.
    [0113] The following discussion and the accompanying figures disclose a variety of concepts relating to knitted components and the manufacture of knitted components. Although the mesh components can be used in a variety of products, a shoe item that incorporates one of the mesh components is described below as an example.
    [0114] The previous description of the embodiments has been provided for purposes of illustration and description. It should not be exhaustive or limit disclosure. The individual elements or characteristics of a particular embodiment are generally not limited to the particular embodiment, but, where applicable, are compatible and can be used in a selected embodiment, even if they are not specifically shown or described. They can also vary in many ways. Such variations should not be considered as a departure from disclosure, and all such changes should be included within the scope of the disclosure.
