  FIG. 1 is an isometric view of one embodiment of an article of footwear 100, also referred to simply as “article 100”. Article 100 is used for a wide variety of footwear including, but not limited to, hiking boots, soccer shoes, football shoes, sneakers, running shoes, cross training shoes, rugby shoes, basketball shoes, baseball shoes and other types of shoes. You may comprise in order to do. Further, in some embodiments, the article 100 includes, but is not limited to, slippers, sandals, high heels, loafers and any other type of footwear, clothing and / or sports equipment (eg, gloves, helmets, etc.). It may be configured for use with various types of non-sport related footwear.

  In some embodiments, the footwear article 100 can include an upper 102 and a sole system 110. The sole system 110 is fixed to the upper 102 and extends between the foot and the ground when the footwear article 100 is worn. In different embodiments, the sole system 110 can include different parts. For example, the sole system 110 can include an outsole, a midsole, and / or an insole. In some cases, one or more of those components may be optional.

  Sole system 110 may provide one or more functions to article 100. For example, in some embodiments, the sole system 110 can be configured to provide traction to the article 100. In addition to providing traction, the sole system 110 may weaken ground reaction forces when compressed between the foot and the ground during walking, running or other walking activities. In different embodiments, the configuration of sole system 110 may vary significantly to include a variety of conventional or non-conventional structures. In some cases, the configuration of the sole system 110 can be selected according to one or more types of ground on which the sole system 110 may be used. Examples of the ground include, but are not limited to, natural grass, artificial grass, soil, and other surfaces.

  In general, the upper 102 can be composed of any type of upper. In particular, the upper 102 can have any design, shape, size and / or color. For example, in an embodiment where the article 100 is a basketball shoe, the upper 102 may be a high top upper shaped to provide high support for the ankle. In embodiments where the article 100 is a running shoe, the upper 102 may be a low top upper.

  With reference to FIG. 1, for reference purposes, the components of the article 100, such as the upper 102, can be divided into a forefoot portion 10, a midfoot portion 12 and a heel portion 14. The forefoot portion 10 is generally associated with the toes and joints that connect the metatarsals to the phalanges. The midfoot portion 12 is generally associated with the arch. Similarly, the heel portion 14 is generally associated with a foot heel including the ribs. Further, the upper 102 can include a lateral side 16 and an inner side 18. Specifically, the lateral side surface 16 and the inner side surface 18 are opposing side surfaces of the article 100. Further, both the lateral side surface 16 and the inner side surface 18 may extend through the forefoot portion 10, the midfoot portion 12 and the heel portion 14.

  Of course, the forefoot portion 10, midfoot portion 12 and heel portion 14 are for illustrative purposes only and are not intended to delimit the exact region of the upper 102. Similarly, the lateral side surface 16 and the inner side surface 18 do not delimit the upper 102 in exactly two halves, but are intended to schematically show the two sides of the upper 102.

  For the sake of consistency and for reasons of convenience, the adjectives for directionality are used throughout this detailed description corresponding to the illustrated embodiments. Throughout this detailed description and claims, “longitudinal” refers to the longitudinal direction of the part. For example, the longitudinal direction of the upper 102 can extend from the forefoot portion 10 of the upper 102 to the heel portion 14. Also throughout this detailed description and claims, “lateral” refers to the width direction of the part. For example, the lateral direction of the upper 102 can extend between the inner side 18 and the side 16 of the upper 102. Further, throughout this detailed description and claims, “vertical” refers to a direction perpendicular to both the longitudinal and lateral directions.

  Further, “proximal” refers to the portion of the footwear component that is close to the foot portion when the footwear article is worn. Similarly, “proximal direction” refers to a direction toward the foot when the article is worn. "Distal" refers to the portion of the footwear component that is away from the foot portion when the footwear article is worn. “Distal direction” refers to the direction directed away from the foot when the article is worn.

  In some embodiments, the upper 102 may be constructed of a braided structure, such as a braided fabric or other braided structure. A braided structure can be formed by twisting three or more strands of yarns, filaments or other fibers to form the structure. As an example, the upper 102 is formed from a plurality of strands 130 that are knitted to form a shape generally similar to the shape of the foot, as seen in FIG.

  Braiding can be used to form a three-dimensional structure by braiding yarn strands on a formwork or shoe mold. The braided strands, such as the plurality of strands 130 in the examples, can be made from fibers such as nylon, carbon, polyurethane, polyester, cotton, aramid (eg, Kevlar®), polyethylene or propylene. . The strands can be braided to form a three-dimensional structure for a wide range of applications.

  Braided structures are manufactured manually or are incorporated herein by reference in their entirety, US Pat. No. 7,252,028, US Pat. No. 8,261,648, US Pat. It can be manufactured using an automatic braiding machine such as a machine described in US Pat. No. 5,361,694 (Patent Document 3), US Pat. No. 5,398,586 (Patent Document 4) and US Pat. No. 4,275,638 (Patent Document 5). Such 3D braided structures may be manufactured for specific designs, for example, by TEF Braids (Warrensburg, NY) or A & P Technology (Cincinnati, Ohio).

  By using a braid, an upper for an article of footwear can be designed with specific functions tailored to a specific athletic or entertainment activity. The braided upper fits snugly and comfortably on the wearer's foot while at the same time being very lightweight. In some embodiments, the fit of the upper may be adjusted to provide some degree of tension or tightening that the wearer may prefer. The braided upper is characterized by a close containment that covers the wearer's foot. In some embodiments, the braided fabric may wrap around the footwear from end to end, as shown in the drawings. Such a structure has tension integrity or “tensegrity” because the braided strands tension around the wearer's foot while the wearer's foot is compressed.

  Some embodiments may include a braided upper that extends under the foot, thereby forming a 360 degree coverage in some regions of the foot. However, other embodiments need not include an upper that extends under the foot. In another embodiment, for example, a braided upper can have a lower periphery coupled with a sole structure and / or insole.

  FIG. 2 illustrates an exploded isometric view of one embodiment of the article 100 that includes an upper 102 configured with a braided structure. 1 and 2, it can be seen that the upper 102 has an opening 120 that can receive a foot. Further, the upper 102 has a tightening region 124. The clamping region 124 may further include a clamping gap 125 that separates the lateral clamping edge 126 and the inner clamping edge 127 (see FIG. 2).

  The clamping region 124 may further be associated with the clamping member 160. In the embodiment, the fastening member 160 may be a string. However, in other embodiments, the clamping member 160 may include any other, including but not limited to straps, snaps, buttons, zippers, hook-and-loop fasteners (eg, Velcro®), and other types of fasteners. It can be a type of fastener.

  Embodiments utilizing a braided upper can include equipment useful for providing the upper with additional structure. In some embodiments, for example, the article includes one or more additional material portions that are joined or attached to a particular portion of the braided upper to enhance various properties of the upper. May be included. For example, these material parts can be used to improve strength and durability, to provide stretch resistance to some locations in the upper, and to facilitate the joining of other components to the braided structure In addition, it may be used.

  Throughout the detailed description and in the claims, an “overlay portion” or “overlay” refers to any portion of a material that is attached to the surface of a braided structure, such as a braided upper. In some embodiments, the overlay portion is composed of a material that is different from the braided strand. Further, in some embodiments, the overlay portion may have material properties that are substantially different from the braided strands. In an embodiment, the overlay portion can withstand stretching as compared to the corresponding portion of the braided structure.

  In general, the overlay portion can be formed of any material. Examples of materials include, but are not limited to, fabrics (including woven and non-woven), leather (including natural and synthetic leather), polymeric materials, and other types of materials. In one embodiment, one or more overlay portions may be formed of thermoplastic polyurethane (TPU).

  In one example, article 100 may be associated with overlay component 140. The overlay component 140 may further comprise a number of different overlay portions including a first overlay portion 150, a second overlay portion 152, and a third overlay portion 154. Each overlay portion may be provided at a specific position on the upper. For example, the first overlay portion 150 may be coupled with the clamping region 124 of the upper 102. Similarly, the second overlay portion 152 may be coupled to the opening 120. Finally, the third overlay portion 154 may be coupled to the heel portion 14 and a portion of both the lateral side 16 and the inner side 18 of the upper 102.

  Referring now to FIG. 2, in some embodiments, the first overlay portion 150 extends along the edge of the clamping region 124. Specifically, the first overlay portion 150 includes a first section 181 associated with the lateral clamping edge 126 of the clamping area 124. The first overlay portion 150 also includes a second section 182 associated with the inner clamping edge 127 of the clamping area 124. In some embodiments, the intermediate section 183 extends along the foremost edge 129 of the clamping region 124 and is coupled to the first section 181 and the second section 182 of the first overlay portion 150.

  In this case, the first overlay portion 150 may form lateral and inner eyestays for the upper 102 or may form portions of lateral and inner eyestays for the upper 102. Specifically, the first overlay portion 150 can facilitate attachment of the upper 102 and the fastening member 160. As described in more detail below, the use of overlay portions along the edges of the clamping region 124 can help to more evenly distribute the tension applied to the upper 102 by the clamping member 160.

  In at least some embodiments, the first overlay portion 150 completes the braided structure of the upper 102 along the lateral clamping edge 126, the inner clamping edge 127, and the foremost edge 129 of the clamping region 124. Can be useful. Specifically, in embodiments where the braided strands may be opened at either the lateral clamping edge 126, the inner clamping edge 127, or the foremost edge 129, the first overlay portion 150 includes: To prevent the strands from unraveling along their edges, it can be useful to join, fuse, or hold the ends of the strands in place.

  In some embodiments, the second overlay portion 152 extends along the edge of the opening 120. Specifically, the second overlay portion 152 is associated with the open edge 195. Further, in some embodiments, the second overlay portion 152 may include the first overlay portion 150 or the second overlay portion such that all edges of the upper 102 associated with the opening 120 and / or the opening in the clamping region 124 Substantially continuous with the first overlay portion 150 as covered by 152.

  This configuration helps to complete the open edge 195 by joining any open strand to the second overlay portion 152. Further, the second overlay portion 152 can help to reinforce the opening 120 so that the braided structure near the opening 120 does not extend excessively. Such reinforcement is particularly effective in the opening 120 because the opening 120 may be subject to large tensile and other stresses when the user inserts and / or pulls out his or her foot. It can be.

  In some embodiments, the third overlay portion 154 may include a first section 171 extending along the lateral side 16 and a second section 172 extending along the inner side 18 of the upper 102. . Further, the third section 173 of the third overlay portion 154 may extend below the upper 102 (eg, the lower surface) at the heel portion 14. In some embodiments, the third compartment 173 joins the first compartment 171 and the second compartment 172 such that the third overlay portion 154 continuously wraps around the sides and bottom of the upper 102. .

  In some embodiments, the first section 171 of the third overlay portion 154 extends from the first section 181 of the first overlay portion 150 and is continuous with the first section 181 of the first overlay portion 150. Formed. Further, in some embodiments, the second section 172 of the third overlay portion 154 extends from the second section 182 of the first overlay portion 150 and together with the second section 182 of the first overlay portion 150. It is formed continuously. Since the third overlay portion 154 can act to reduce the elongation along its length, this configuration can result in the first overlay portion 150 (at the top of the foot) and the lower side 199 of the heel portion 14. By resisting the extension of the upper between (see FIG. 8), it can help to improve the support under the heel.

  FIG. 3 shows an enlarged view of a portion of the article 100, where some strands may be joined to the second overlay portion 152. With reference to FIG. 3, several strands 304 may be disposed relative to the inner surface 302 of the second overlay portion 152. In this embodiment, the strands 304 may form part of the closed woven edge 305 of the upper 102 that lacks the free or free ends of some strands. In this case, the strands 304 may be joined to the second overlay portion 152 to reinforce the continuously woven section of the braided structure.

  In the alternative embodiment shown in FIG. 4, some strands 470 may be comprised of free or free ends 472. In this configuration, the open end 472 may be secured to the overlay portion 452 to hold the strand 470 in place and to help prevent the strand 470 from loosening or unraveling. . Thus, it can be seen that in some embodiments, an overlay portion can be used to retain the free or free end associated with the edge of the braided structure. Such a configuration can provide a means of finishing the edges of the braided structure, or any edges including free or free ends that may be unraveled.

  The configurations disclosed herein provide an overlay portion that can act to reinforce the edge of the braided structure at the opening 120. This can help to reduce the elongation of the upper 102 in the opening 120 to maintain the structural integrity of the upper 102. Further, the second overlay portion 152 can serve to secure any free or open end of the braided structure to prevent end fraying and / or unraveling of the braided structure.

  Hereinafter, various processes for joining the overlay portion to a braided structure such as a braided upper will be described in more detail. Examples of materials used to bond include any known adhesive, lysate, resin or other bonding agent.

  FIG. 5 is an isometric view of the article 100 including a portion of the first overlay portion 150 and a schematic enlarged cross-sectional view of the clamping member 160. Referring to FIG. 5, the first overlay portion 150 includes a plurality of eyelets 400. Specifically, the plurality of eyelets 400 including the eyelet 402 shown in the enlarged cross-sectional view is an opening in the first overlay portion 150 configured to receive a portion of the fastening member 160.

  In contrast to an alternative embodiment where the strands of the upper 102 are secured directly to a portion of the clamping member, this example shows that the strands of the upper 102 are clamped via eyelets in the first overlay portion 150. It can be configured to be indirectly fixed to the member 160. Specifically, the strand 410 is illustrated as being secured directly to the first overlay portion 150, but the clamping member 160 is secured through the plurality of eyelets 400 in the first overlay portion 150. In this configuration, the force transmitted to the entire braided structure of the upper 102 can be dispersed by tightening the member 160 more uniformly. This can prevent, for example, the clamping member 160 from excessively pulling a particular strand, thereby promoting better comfort and fit to the foot of the article 100.

  6 and 7 show two possible configurations for the strands near the eyelet of the overlay portion. First, referring to FIG. 6, in some embodiments, one or more strands may extend around the eyelet, thereby acting to reinforce the eyelet. For example, in FIG. 6, the first strand 512 and the second strand 514 are wound around the first eyelet 502 and the second eyelet 504, respectively. This has the effect of reinforcing the first eyelet 502 and the second eyelet 504 and the effect of providing a more direct transmission of tension between the fastening member 160 and the braided strand of the upper 102.

  Referring to the alternative embodiment shown in FIG. 7, the first eyelet 502 and the second eyelet 504 are not surrounded by any strand of the upper. Specifically, it can be seen that the strand 610 is joined to the first overlay portion 150 without surrounding the first eyelet 502 and the second eyelet 504. Of course, in yet another embodiment, some eyelets may be surrounded or reinforced by strands, while other eyelets are not surrounded or reinforced. It does not have to be.

  FIG. 8 is a rear isometric view of the upper 102 illustrating the strands 130 of the upper 102 in phantom. Referring to FIG. 7, it can be seen that the third overlay portion 156 wraps under the lower side 199 of the upper 102 at the heel portion 14. In some cases, this configuration allows the third overlay portion 156 to hold the footpad. Accordingly, this configuration can provide additional support for the toe of the foot when the article 100 is worn by reducing the stretch through the heel portion 14.

  In some embodiments, multiple separate overlay components may be used. In some embodiments, the separate overlay components may be configured to intersect or overlap at predetermined portions of the upper. Such a configuration of overlaying overlay components can provide a means to increase strength and stretch resistance over most of the upper, potentially including the entire upper.

  9-11 illustrate one embodiment of an article of footwear 800 that includes an upper 802 and a sole structure 805 (shown only in FIG. 10). First, referring to FIG. 9, the upper 802 has a braided structure that is braided by a plurality of strands 830. In addition, a plurality of overlay parts including a first overlay part 810, a second overlay part 812, a third overlay part 814 and a fourth overlay part 816 are associated with the upper 802.

  In the exemplary embodiment, each overlay component is associated with a particular portion of upper 802. For example, the first overlay component 810 is associated with the edge 870 of the opening 860 and the clamping region 862. Accordingly, in some cases, the first overlay component 810 may be used to finish a plurality of strands 830 along the edge 870. Furthermore, the first overlay component 810 can impart stretch resistance in the vicinity of the opening 860.

  The second overlay component 812 is associated with the front toe portion 868 of the upper 802. In some embodiments, the second overlay component 812 can help improve stretch resistance at the front toe portion 868. Further, in some embodiments, the second overlay component 812 can provide a coating for the front toe portion 868. Specifically, the presence of the second overlay component 812 can help prevent debris from entering the upper 802 via the front toe portion 868.

  The third overlay component 814 may be associated with the forefoot portion 811 of the upper 802. In some embodiments, the third overlay component 814 may be positioned in front of the clamping region 862. Furthermore, as can be seen in FIG. 9, the third overlay component 814 can completely surround the upper 802 (and the foot within the upper 802). In an embodiment, the third overlay component 814 is comprised of a first band 817 and a second band 819 that are joined together at the upper intersection region 815. Accordingly, this configuration can provide the forefoot portion 811 with a targeted stretch resistance that improves the support of the active foot, which may cause the forefoot portion 811 to step firmly on the ground.

  The fourth overlay component 816 may be associated with the heel portion 813 of the upper 802. In some embodiments, the fourth overlay component 816 may include a heel counter-like overlay portion 825 and a strap-like overlay portion 827. Combining the overlay portion 825 and the overlay portion 827 can help limit the stretchability at the heel portion 813 and thus can enhance the support of the heel within the upper 802.

  As is apparent from FIGS. 10 and 11, when assembled with the upper 802, some of the overlay components can overlap one another. For example, it can be clearly seen that the third overlay component 814 overlaps a portion of the first overlay component 810 in the overlap region 902. Further, it can be seen that the third overlay component 814 overlaps a portion of the second overlay component 812 in the overlap region 903. Similarly, it can be clearly seen that the fourth overlay component 816 overlaps a portion of the first overlay component 810 in the overlap region 904. This overlapping arrangement can help to increase the structural integrity of the upper 802 because a portion of one overlay part can reinforce the support of the overlapping overlay parts. Furthermore, by overlaying and joining portions of different overlay components together, the overlay components may function as an integral frame for supporting the braided structure of the upper 802.

  Embodiments using braided regions having different characteristics may include equipment that further reinforces some regions but does not reinforce other regions. In some embodiments, the article may include an overlay portion that is configured to cover a predetermined area of the article.

  FIGS. 12 and 13 are isometric views of an article 1100 configured with an overlay portion covering two specific areas of the upper 1102. Specifically, FIG. 12 shows an isometric exploded view of article 1100 and FIG. 13 shows an isometric view including an enlarged cross-sectional view. With reference to FIGS. 12 and 13, the article 1100 includes an upper 1102 and a sole system 1110. The upper 1102 further includes at least four separate regions including a first region 1151, a second region 1152, a third region 1153, and a fourth region 1154. In the embodiment, the first region 1151 is a toe region of the upper 1102. The second region 1152 is directly adjacent to the first region 1151 and behind it. The third region 1153 is disposed adjacent to and behind the second region 1152. Finally, the fourth area 1154 extends behind the third area 1153. Further, the fourth region 1154 is a substantially larger region than the remaining regions, and includes the entire midfoot portion 1103 and the heel portion 1105 of the upper 1102. Accordingly, the first region 1151, the second region 1152, and the third region 1153 may be characterized as a band of the upper 1102 that extends laterally across the entire upper 1102.

  Each region of the upper 1102 may be associated with specific material properties such as braid density. In the example, both the first region 1151 and the third region 1153 are associated with the first braid density, and the second region 1152 and the fourth region 1154 are associated with the second braid density. In some embodiments, the first braid density may be greater than the second braid density. Thus, the first region 1151 and the third region 1153 can be tightly knitted to provide a region with increased strength and, in some embodiments, can withstand elongation.

  Article 1100 may further be associated with a first overlay portion 1160 and a second overlay portion 1162. The first overlay portion 1160 may be shaped to cover the first region 1151 of the upper 1102. The second overlay portion 1162 may be shaped to cover the third region 1153 of the upper 1102. For example, as illustrated in the enlarged cross-sectional view of FIG. 13, the second overlay portion 1162 may be disposed on the strand 1170 of the third region 1153. With this arrangement, the first overlay portion 1160 and the second overlay portion 1162 can further reinforce the first region 1151 and the second region 1152, thereby increasing support and stretch resistance in those regions. be able to.

  The examples only illustrate some possible configurations for the overlay portion for the upper. It should be understood that some other embodiments may include an overlay portion configured with a variety of different shapes, sizes and arrangements. Further, in alternative embodiments, any number of separate overlay components may be used. The quantity, shape, size, and placement of the overlay component or portion provides the desired properties including stretch resistance, high strength, support, comfort or any other desired properties at any location on the footwear article You can choose to do.

  As described in the braided upper application, the braided upper can be configured with a variety of different features and functions. The overlay portion described in this detailed description is utilized with a variety of different embodiments of a braided upper that may or may not include some of the features described in the braided upper application. It should be understood that it may be. As an example, in some embodiments, strands having different material properties can be knitted or associated with each other to impart specific properties to one or more regions of the upper. For example, the upper may be manufactured from fibers that stretch to some extent as the wearer's foot moves with each stride he or she takes, thereby increasing the wearer's comfort. In this case, high tensile strength, non-stretchable fibers may be inserted through those specific areas of the footwear that require additional structural support. As another example, the upper may be manufactured with additional open braids in some areas, for example to improve breathability or comfort. In this case, the additional fibers can be braided to provide additional support to some parts of those areas or to provide high durability to the high impact areas of the footwear. You may pass. The upper having any of these configurations may further include one or more overlay portions to further control the properties and functionality of the upper, including support and / or stretch resistance in various areas of the upper. May be associated.

  The upper may also have floating cables, i.e., cables that are not braided into the fabric of the upper may be utilized to relieve stress on some sections of the upper. The floating cable may be formed of a different material that is separate from the braid structure and not attached to the braid structure. The cable may also be used as a string to secure the footwear to the foot or to tighten several portions of the footwear, as will be described below. For example, the cable may, for example, secure the first end to the sole of the footwear and the second end to the eyelet. Such floating cables may also be used to increase the support and stability of some parts of the footwear, such as around the ankle opening. In some embodiments, the overlay portion may be used with a braided upper that includes a floating cable, and in some cases, the overlay portion reinforces a portion with or without a cable. You may use for. In some embodiments, the overlay portion can also be used to help secure the end of the floating cable to the upper.

  Combinations of these features, including any of the features described in the aforementioned braided upper application, together with the overlay portion described and illustrated above, can be used for specific exercise or entertainment activities. Manufacture can be facilitated. A braided upper with a combination of these features can fit snugly and comfortably on the wearer's foot while being very lightweight. In some embodiments, the fit of the upper may be adjusted to provide a certain degree of tension or tightening that the wearer may prefer.

  14-17 illustrate some steps in an exemplary process for forming an article composed of a braided upper and overlay portion. First, as shown in FIG. 14, the braided upper 1402 can be formed using any braiding process. An exemplary process for forming a braided article is described above and described in a braided upper application that is incorporated by reference. Next, as shown in FIG. 15, in some embodiments, an opening 1502 can be cut into the upper 1402. This can produce a new edge 1504 adjacent to the opening 1502. Opening 1502 can be used for foot insertion and can form a region for fasteners such as strings.

  In an embodiment, overlay portion 1510 may then be joined along edge 1504 (see FIG. 15) of upper 1402, as shown in FIG. In some embodiments, bonding may be achieved using a welding process, such as an ultrasonic welding process. Thereby, the strands exposed along the edge 1504 can be fused to the overlay portion 1510 to finish the edge and reinforce and support the edge 1504 when the article is clamped. be able to. Finally, the string 1602 can be inserted through the eyelet 1610 as shown in FIG. Further, in some embodiments, a sole system 1620 can be added to the bottom of the upper 1402.

  Some embodiments can include equipment to facilitate the coupling of the upper and sole systems. In some embodiments, an overlay portion may be provided between the upper and the sole system, thereby facilitating coupling of the upper and the sole system.

  18 and 19 are isometric views of an embodiment in which the overlay portion can be used to assist in attaching the sole system to the upper. 18 and 19, upper 1702 can be associated with overlay component 1720 and overlay component 1722. In some embodiments, the overlay component 1720 may be associated with the opening 1716 of the upper 1702. Overlay component 1722 can be associated with lower side 1703 of upper 1702. In some embodiments, the overlay component 1722 may extend across the lower side 1703, while in other embodiments, the overlay component 1722 extends over only a portion of the lower side 1703. May extend. Further, in some cases, the overlay component 1722 may extend partially upward around the lower periphery 1705 of the upper 1702.

  In some embodiments, the sole system 1730 can be associated with the upper 1702. Further, in some embodiments, overlay component 1722 can facilitate joining or coupling of sole system 1730 to upper 1702. For example, as clearly shown in the enlarged cross-sectional view of FIG. 19, the overlay component 1722 includes a sole system 1730 and a lower side 1703 of the upper 1702 to facilitate coupling of the sole system 1730 and the upper 1702. Can be placed between.

  In some embodiments, the material properties of overlay component 1722 and sole system 1730 can be selected so that overlay component 1722 and sole system 1730 can be easily joined using an adhesive or other process. For example, in some embodiments, the overlay component 1722 may be formed of a thermoplastic urethane (TPU) material and the sole system 1730 is formed of a similar material or a material that readily bonds to the TPU. It is intended that it may be. However, in still other embodiments, overlay component 1722 and sole system 1730 can be formed of any other material that can be bonded with or without separate adhesives.

  20-24 illustrate an embodiment of an article of footwear 2000 or simply article 2000. In some embodiments, the article can comprise an upper having a plurality of braided structures. First, referring to FIG. 20, an article 2000 includes a sole system 2002 and an upper 2004. The sole system 2002 is similar to the sole system 110 of FIG. The upper 2004 includes a first braided structure 2006 and a second braided structure 2008. Further, for reference purposes, the components of article 2000, such as upper 2004, can be divided into a forefoot portion 10, a midfoot portion 12, and a heel portion 14.

  Similar to the upper 102 of FIG. 1, the upper 2004 can have any design, shape, size and / or color. For example, in an embodiment where the article 2000 is a basketball shoe, the upper 2004 may be a high top upper shaped to provide high support for the ankle. In embodiments where the article 2000 is a running shoe, the upper 2004 may be a low top upper.

  In some embodiments, the first braided structure 2006 and the second braided structure 2008 are formed by twisting three or more strands of yarns, filaments or other fibers to form the structure. can do. For example, the first braided structure 2006 is formed from a plurality of strands (eg, strands 2030) that are knitted to form a shape that is generally similar to the shape of the foot. Similarly, the second braided structure 2008 can be formed from a plurality of strands (eg, strands 2040) that are knitted to form a shape generally similar to the shape of the foot. Strand 2030 and / or strand 2040 can be formed from the same materials and methods as strand 130 (see FIG. 1).

  In some embodiments, the first braided structure 2006 and the second braided structure 2008 have similar structures. For example, both the first braided structure 2006 and the second braided structure 2008 can utilize a specific weaving pattern. In some embodiments, the first braided structure 2006 and the second braided structure 2008 can both have a specific weaving density. In one embodiment, both the first braided structure 2006 and the second braided structure 2008 can be formed utilizing a specific weaving structure.

  In certain embodiments, strand 2030 and strand 2040 have a similar structure. In some embodiments, the strand 2030 and the strand 2040 have a common thickness. In one embodiment, strand 2030 and strand 2040 are manufactured from a common material. For example, strand 2030 and strand 2040 can include filaments impregnated with a thermoplastic material.

  In another embodiment, the first braided structure 2006 and the second braided structure 2008 may be different. The differences can include, for example, weaving techniques, structure, weaving density, filament type, filament processing, and the like. For example, the first braided structure 2006 can be formed from a weave and structure having a soft yarn that has a soft feel, has a low density, and is further processed to be hydrophobic. In an embodiment, the second braided structure 2008 can be formed from a weave and structure having carbon fibers that are further processed to maximize durability, have high density, and be reinforced with resin.

  Various characteristics of the braided structure (eg, first braided structure 2006, second braided structure 2008, etc.) may be configured in the structure or may vary. For example, the forefoot portion 10 of the first braided structure 2006 can utilize a stronger weaving technique than the weaving technique utilized in the heel portion 14 of the first braided structure 2006. Similarly, the forefoot portion 10 of the first braided structure 2006 can utilize a more uneven structure than the structure utilized in the heel portion 14 of the first braided structure 2006. Further, the forefoot portion 10 of the first braided structure 2006 can utilize a higher density weaving than the weaving utilized in the heel portion 14 of the first braided structure 2006. Further, the forefoot portion 10 of the first braided structure 2006 can utilize a filament that is more robust than the filament utilized in the heel portion 14 of the first braided structure 2006. Such a filament can be made robust, for example, by impregnating the filament with a resin. The embodiments described above relate to the first braided structure 2006, but these embodiments can also be applied to the second braided structure 2008.

  In some embodiments, the braided structure can have cooperative properties. For example, both the first braided structure 2006 and the second braided structure 2008 can use a higher density weaving in the heel portion 14 than in the midfoot portion 12. In another embodiment, one of the braided structures has a change in a characteristic that does not correspond to another braided structure. For example, the first braided structure 2006 generally utilizes a specific weaving technique, while the second braided structure 2008 includes a heel portion 14 and a forefoot portion 10 having different characteristics.

  In one aspect, the braided structure is formed separately (braided) and subsequently combined or formed simultaneously. For example, a first shoe mold is inserted into a braiding machine to produce a first braided structure 2006, and a second shoe mold is inserted into the braiding machine or another braiding machine to create a second braid. Fabricate structure 2008. Alternatively, a single shoe mold may be inserted into the braiding machine to produce the first braided structure 2006 and the second braided structure 2008.

  In various embodiments, the first braid structure 2006 and the second braid structure 2008 are held by the overlay system 2140. Overlay system 2140 can be manufactured similarly to overlay component 140. For example, the overlay system 2140 can be formed from a thermoplastic material and includes an eyelet 2122 for a clamping member 2123 (eg, the clamping member 160).

  In some embodiments, the stretch resistance of overlay system 2140 may differ from one or more braided structures. For example, in some embodiments, the overlay system 2140 can be more stretch resistant (eg, stretchless) than the first braided structure 2006 and / or the second braided structure 2008. However, in another embodiment, the overlay system 2140 can have the same stretch resistance as the first braided structure 2006 and / or the second braided structure 2008.

  In certain embodiments, the overlay system includes a first layer to prevent the first braided structure from overstretching. For example, as shown in FIG. 21, the overlay system 2140 includes a first layer 2144 formed on the first braided structure 2006. Similarly, in some embodiments, the overlay system includes a second layer to prevent the second braid structure from over-extending. For example, as shown in FIG. 21, the overlay system 2140 includes a second layer 2142 formed on the second braided structure 2008.

  In different embodiments, the second layer includes a first overlay portion for supporting the heel region of the foot. For example, the second layer 2142 includes a first overlay portion 2154 associated with the heel portion 14. In one embodiment, the first overlay portion 2154 can limit the stretchability of the second braided structure 2008 to support a foot inserted into the article 2000. In some embodiments, the first overlay portion extends into the lateral and inner sides of the upper. For example, as shown, the first overlay portion 2154 extends into the lateral side 16 and the inner side 18. In another embodiment, the first overlay portion extends to either the lateral side or the inner side. For example, the first overlay portion 2154 extends into the lateral side 16 and is separate from the inner side 18 (not shown). In another embodiment, the first overlay portion 2154 extends into the inner side surface 18 and is separate from the lateral side surface 16 (not shown).

  In some embodiments, the second layer includes a second overlay portion for supporting the article during foot insertion. For example, the second layer 2142 includes a second overlay portion 2152 associated with the opening 2120. In one embodiment, the second overlay portion 2152 limits the stretching of the second braided structure 2008 to allow the foot to be inserted into the article 2000 without excessively stretching the second braided structure 2008.

  In one embodiment, the second layer includes a third overlay portion for supporting the clamping area so that the article can be clamped to the foot. For example, the second layer 2142 includes a third overlay portion 2150 associated with the clamping region 2124. As shown, in one embodiment, the third overlay portion 2150 can include an eyelet 2122 for receiving a clamping member 2123. Further, in some embodiments, the third overlay portion 2150 can be used to stretch the second braided structure 2008 to allow tagging of the clamping member 2123 without excessive stretching of the second braided structure 2008. Can be limited.

  In some embodiments, the overlay portion is substantially continuous and covers the various edges of the upper 2004. For example, as shown in FIG. 21, the first overlay portion 2154, the second overlay portion 2152, and the third overlay portion 2150 are substantially continuous. In another embodiment, the third overlay portion 2150 is substantially continuous with the second overlay portion 2152 and the third overlay portion 2150 is separate from the first overlay portion 2154. In one embodiment, the third overlay portion 2150 is substantially continuous with the first overlay portion 2154 and the third overlay portion 2150 is separate from the second overlay portion 2152. In some embodiments, the second overlay portion 2152 is substantially continuous with the first overlay portion 2154 and the second overlay portion 2152 is separate from the third overlay portion 2150.

  As described above, in various embodiments, the overlay system includes a first layer to prevent the first braided structure from overstretching. For example, as shown in FIG. 21, the overlay system 2140 includes a first layer 2144 formed on the first braided structure 2006. In some embodiments, the first layer 2144 is similar to the second layer 2142. For example, the first layer 2144 can include a sixth overlay portion 2156 associated with the clamping region 2124. In another example, the first layer 2144 includes a fifth overlay portion 2158 associated with the opening 2120. In yet another embodiment, the first layer 2144 includes a fourth overlay portion 2160 associated with the heel portion 14. In another embodiment, the first layer 2144 and the second layer 2142 are different.

  In one embodiment, the overlay system extends along the open edge to support the first braided structure and / or the second braided structure. For example, as shown in FIG. 21, the fifth overlay portion 2158 can extend over the first open edge 2296. This arrangement helps to finish the first open edge 2296 of the first braided structure 2006 by joining some open strands to the fifth overlay portion 2158. In another example, the second overlay portion 2152 extends over the second open edge 2196. Similar to the above, this arrangement helps to finish the second open edge 2196 of the second braided structure 2008 by joining some open strands to the second overlay portion 2152.

  In some embodiments, the overlay system extends along a lateral midfoot edge to support the first braided structure and / or the second braided structure. For example, as shown in FIG. 21, the fifth overlay portion 2158 can extend on the first lateral metatarsal edge 2230. This arrangement helps to finish the first lateral metatarsal edge 2230 by joining any open strand to the fifth overlay portion 2158. In another embodiment, the second overlay portion 2152 extends on the second lateral metatarsal edge 2130. Similar to that described above, this arrangement helps to finish the second lateral midfoot edge 2130 of the second braided structure 2008 by joining any open strands to the second overlay portion 2152.

  In various embodiments, the overlay system extends along the medial midfoot edge to support the first braided structure and / or the second braided structure. For example, as shown in FIG. 21, the fifth overlay portion 2158 can extend on the first inner metatarsal edge 2232. This arrangement helps to finish the first inner metatarsal edge 2232 by joining the open strand to the fifth overlay portion 2158. In another embodiment, the second overlay portion 2152 extends on the second medial midfoot edge 2132. Similar to the above, this arrangement helps to finish the second inner metatarsal edge 2132 by joining the open strands to the second overlay portion 2152.

  In some embodiments, the overlay system extends along the forward clamping edge to support the first braided structure and / or the second braided structure. For example, as shown in FIG. 21, the sixth overlay portion 2156 can extend on the first forward clamping edge 2229. This arrangement helps to finish the first forward clamping edge 2229 by joining any open strand to the sixth overlay portion 2156. In another embodiment, the third overlay portion 2150 extends on the second forward clamping edge 2129. Similar to the above, this arrangement helps to finish the second forward clamping edge 2129 of the second braided structure 2008 by joining any open strands to the third overlay portion 2150.

  In one embodiment, the overlay system extends along the lateral clamping edge to support the first braided structure and / or the second braided structure. For example, as shown in FIG. 21, the sixth overlay portion 2156 can extend on the first lateral clamping edge 2226. This arrangement helps to finish the first lateral clamping edge 2226 by joining any open strand to the sixth overlay portion 2156. In another embodiment, the third overlay portion 2150 extends over the second lateral clamping edge 2126. Similar to that described above, this arrangement helps to finish the second lateral clamping edge 2126 of the second braided structure 2008 by joining any open strands to the third overlay portion 2150.

  In various embodiments, the overlay system extends along the inner clamping edge to support the first braided structure and / or the second braided structure. For example, as shown in FIG. 21, the sixth overlay portion 2156 can extend on the first inner clamping edge 2227. This arrangement helps to finish the first inner clamping edge 2227 by joining any open strand to the sixth overlay portion 2156. In another embodiment, the third overlay portion 2150 extends on the second inner clamping edge 2127. Similar to that described above, this arrangement helps to finish the second inner clamping edge 2127 of the second braided structure 2008 by joining any open strands to the third overlay portion 2150.

  In some embodiments, the second braided structure overlaps the outer surface of the first braided structure. For example, as shown in FIG. 22, the inner surface 2010 of the second braided structure 2008 substantially overlaps the outer surface 2012 of the first braided structure 2006. As used herein, when a first surface covers at least 60% of the other surface, the surface substantially overlaps another surface. In some cases, the inner surface 2010 and the outer surface 2012 can overlap between 60-100% (eg, 70%, 80%, 90%, 95% or 99%). Further, in one embodiment, the inner surface of the second braided structure is in direct contact with the outer surface of the first braided structure. For example, as shown in FIG. 22, the inner surface 2010 is placed in direct contact with the outer surface 2012. In some embodiments, the overlay system that retains the outer surface of the second braided structure is in direct contact with the outer surface of the first braided structure. For example, the overlay system 2140 can join the inner surface 2010 directly on the outer surface 2012 (see FIG. 24).

  As shown in FIG. 22, the first braided structure 2006 can include strands 2201. The strands 2201 can represent a plurality of strands of the first braided structure 2006 and / or a plurality of strands of the second braided structure 2008. In some embodiments, the first braided structure 2006 may be damaged by pulling the strands 2201. Accordingly, as shown in FIG. 23, an overlay system 2140 can be used to prevent the strands 2201 from being pulled. In some embodiments, the second overlay portion 2152 can be used to prevent the strands 2201 from being pulled.

  Furthermore, as shown in FIG. 22, the second braided structure 2008 can include strands 2203. The strand 2203 can represent a plurality of strands of the first braided structure 2006 and / or a plurality of strands of the second braided structure 2008. In some embodiments, the second braided structure 2008 may be damaged by pulling on the strands 2203. Accordingly, as shown in FIG. 23, an overlay system 2140 can be used to prevent the strands 2203 from being pulled. In some embodiments, the fifth overlay portion 2158 can be used to prevent the strands 2201 from being pulled.

  In various embodiments, the overlay system 2140 can hold the first braided structure 2006 and / or the second braided structure 2008 in a particular position. For example, as shown in FIG. 23, the overlay system 2140 holds the strands 2201 of the first braided structure 2006 and the strands 2203 of the second braided structure 2008 in a fixed position. In one embodiment, the second overlay portion 2152 holds the strands 2203 of the second braided structure 2008 in a fixed position. In some embodiments, the fifth overlay portion 2158 holds the strands 2201 of the first braided structure 2006 in a fixed position.

  In one embodiment, the overlay system holds the first braided structure in a relative position with respect to the second braided structure. For example, as shown in FIG. 23, the overlay system 2140 holds the first braided structure 2006 so as to be in direct contact with the second braided structure 2008. In various embodiments, the second overlay portion 2152 holds the second braided structure 2008 in a fixed position, and the fifth overlay portion 2158 holds the first braided structure 2006 in a fixed position, and the second overlay portion. 2152 and the fifth overlay portion 2158 are joined to hold the first braided structure 2006 relative to the second braided structure 2008.

  In some embodiments, the overlay portion holds the strands of the first braided structure in a fixed position with the strands of the second braided structure. For example, as shown in FIG. 23, the overlay system 2140 holds the first strand 2302 of the first braided structure 2006 so that it directly contacts the second strand 2304 of the second braided structure 2008. In various embodiments, the second overlay portion 2152 holds the second strand 2304 in a fixed position, and the fifth overlay portion 2158 holds the first strand 2302 in a fixed position, and the second overlay portion 2152 and the fifth Overlay portion 2158 is joined to hold first strand 2302 in a relative position with respect to second strand 2304.

  In some embodiments, overlay system 2140 is configured to prevent separation of first braided structure 2006 and second braided structure 2008. For example, as shown in FIG. 24, an inner force 2402 is applied to the second braided structure 2008. Further, in the embodiment, a lateral force 2404 may be applied to the first braided structure. As such, the first braided structure 2006 and the second braided structure 2008 are separated at the central portion 2406. Further, as shown in FIG. 24, overlay system 2140 prevents first braid structure 2006 and second braid structure 2008 from separating at overlay portion 2408. As described above, in some embodiments, the second overlay portion 2152 and the fifth overlay portion 2158 are joined to prevent separation of the first braid structure 2006 and the second braid structure 2008.

  In some embodiments, it may be desirable to provide an intermediate layer to provide a buffering function. For example, FIGS. 25-34 illustrate an embodiment that includes an intermediate layer. As shown in FIG. 25, footwear article 2600 or simply article 2600 is substantially similar to article 2000 except that article 2600 further includes an intermediate layer 2601.

  In one embodiment, the intermediate layer can include any number of members disposed at various locations on the article 2600. For example, as shown in FIG. 25, the intermediate layer 2601 can include an ankle pad 2602 as a first member and a heel pad 2604 as a second member. In another embodiment, the intermediate layer 2601 can include one member or more than two members (see FIG. 26). Further, in some embodiments, the intermediate layer 2601 includes members on other portions of the shoe, such as the midfoot portion 12 and the forefoot portion 10 (not shown).

  In some embodiments, the lateral side 16 can include a third member corresponding to the first member of the inner side 18. For example, the intermediate layer 2601 can include an ankle pad 2702 (see FIGS. 26-27). In some embodiments, ankle pad 2602 has one or more features that are generally similar to ankle pad 2702. In another embodiment, ankle pad 2602 and ankle pad 2702 are different.

  In one embodiment, the lateral surface 16 can include a fourth member corresponding to the second member of the inner side surface 18. For example, the intermediate layer 2601 can include a heel pad 2604 (see FIGS. 26 and 27). In some embodiments, heel pad 2604 has one or more features that are substantially similar to heel pad 2704. In another embodiment, heel pad 2604 and heel pad 2704 are different.

  In some embodiments, it may be desirable to provide a cushioning effect on the user's foot. In such an embodiment, the intermediate layer may be positioned to provide a cushioning effect on the user's foot. For example, as shown in FIG. 27, the ankle pad 2702 is disposed on the ankle portion 15. Further, as shown, the heel pad 2704 is disposed on the heel portion 14.

  In one embodiment, the intermediate layer is formed from a foam. For example, the ankle pad 2602, the heel pad 2604, the ankle pad 2702, and / or the heel pad 2704 can be formed from ethylene vinyl acetate (EVA). In another embodiment, the intermediate layer is formed from a polymer. For example, the ankle pad 2602, the heel pad 2604, the ankle pad 2702 and the heel pad 2704 can be formed from a thermoplastic material.

  In some embodiments, the overlay system substantially surrounds one or more members of the intermediate layer 2601. For example, as shown in FIG. 27, the overlay system 2140 substantially surrounds the ankle pad 2702. As used herein, substantially surrounding includes more than 60% surrounding.

  In various embodiments, the first braided structure 2006 and the second braided structure are separated by an intermediate layer. For example, as shown in FIG. 28, the ankle pad 2702 is disposed between the first braided structure 2006 and the second braided structure 2008. In another embodiment, the heel pad 2704 is disposed between the first braided structure 2006 and the second braided structure 2008.

  In some embodiments, one or more members of the intermediate layer 2601 may be in direct contact with the first braided structure. For example, as shown in FIG. 28, the ankle pad 2702 directly contacts the first braided structure 2006. In another example, the heel pad 2704 directly contacts the first braided structure 2006. Similarly, in some embodiments, one or more members of the intermediate layer 2601 may be in direct contact with the second braided structure. For example, as shown in FIG. 28, the ankle pad 2702 directly contacts the second braided structure 2008. In another embodiment, the heel pad 2704 directly contacts the second braided structure 2008.

  In one embodiment, one or more members in the intermediate layer are held in a fixed position by the overlay system. For example, as shown in FIG. 28, the ankle pad 2702 is held between the first overlay portion 2154 and the second overlay portion 2152. In another example, an ankle pad 2702 is held between fourth overlay portion 2160 and fifth overlay portion 2158. In some embodiments, the heel pad is held in a fixed position by an overlay system and a sole system. For example, as shown, the heel pad 2704 may be held in a fixed position by the first overlay portion 2154. In another example, the heel pad 2704 may be held in a fixed position by the fourth overlay portion 2160.

  In some embodiments, one or more members of the intermediate layer are flexibly held in a fixed position by the overlay system 2140. In one embodiment, the intermediate layer is held flexibly by separating one or more members of the intermediate layer from the overlay system 2140. For example, as shown in FIGS. 27 and 28, the ankle pad 2702 is separated from the second overlay portion 2152. In another embodiment, the ankle pad 2702 is separated from the first overlay portion 2154. In yet another embodiment, the ankle pad 2702 is separated from the fifth overlay portion 2158. In one example, ankle pad 2702 is separated from fourth overlay portion 2160. Similarly, the heel pad 2704 is from one or more of the first overlay portion 2154, the second overlay portion 2152, the third overlay portion 2150, the fourth overlay portion 2160, the fifth overlay portion 2158, and the sixth overlay portion 2156. It may be separated.

  In another embodiment, one or more members of the intermediate layer may be held firmly in place by an overlay system. For example, as shown in FIG. 29, the ankle pad 2602 is firmly attached to the overlay system 2140. In another embodiment, heel pad 2604 is rigidly attached to overlay system 2140.

  In various embodiments, one or more members of the intermediate layer 2601 may contact the overlay system 2140 directly. For example, as shown in FIG. 30, the ankle pad 2602 is in direct contact with the second overlay portion 2152 and / or the fifth overlay portion 2158. In another example, the heel pad 2604 directly contacts the second overlay portion 2152 and / or the fifth overlay portion 2158.

  The embodiments disclosed herein and shown in FIGS. 20-30 provide, for example, means for selectively modifying the material properties of the upper. Specifically, the overlay portion can be applied to selective locations of the upper (not to other locations) to provide stretch resistance, strength, stiffness and / or other material properties at the selective locations. Can be strengthened. For example, in the embodiment shown in FIGS. 20-24, the overlay system 2140 is selectively placed on the edges of the first braided structure 2006 and the second braided structure 2008, but the interior of these edges. It includes overlay portions that are not arranged in some portions (eg, toe portions, portions of the lateral and medial sides, and portions of the lower side of upper 2004). This selective placement in the overlay area can improve stretch resistance and strength at the edge, but retains improved flexibility, relatively low stiffness and breathability in areas not covered by the overlay area can do.

  FIGS. 31 and 32 show the improved functionality of the upper 2004 due to the selective placement of overlay portions in some areas of the upper 2004 (except others). As can be seen in the enlarged cross-sectional view of FIG. 31, the ankle pad 2602 is held between the first braided structure 2006 and the second braided structure 2008. Further, in order to prevent the ankle pad 2602 from moving outside the ankle region of the upper 2004, the second overlay portion 2152 and the fifth overlay portion 2158 are connected to the first braid structure 2006 and the second braid structure 2008 (mutually). To help hold the ankle pad 2602 in a predetermined upper 2004 area. In particular, the second overlay portion 2152 and the fifth overlay portion 2158 are arranged around the ankle pad 2602 so that the ankle pad 2602 cannot move outside the boundary defined by the second overlay portion 2152 and the fifth overlay portion 2158. The first braided structure 2006 and the second braided structure 2008 are attached.

  In some embodiments, the upper 2004 can improve shock absorption by dispersing the impact force on the intermediate layer 2601. For example, FIG. 31 shows an ankle pad 2602 positioned to protect the ankle 2706. Further, as shown, the first braid structure 2006 and the second braid structure 2008 support an ankle pad 2602. As shown in FIG. 32, in the embodiment, the force 2708 that contacts the second braided structure deforms the second braided structure 2008 and disperses the force 2708. Such deformation helps intermediate layer 2601 (eg, ankle pad 2602) absorb shock by dispersing impact force 2708 to intermediate layer 2601.

  Since the second braided structure 2008 has low rigidity and is relatively flexible, it can be easily deformed. This is an overlay that is specially designed to limit flexibility and enhances the connection between the first braided structure 2006 and the second braided structure 2008 by increasing the overall stiffness of these areas. In contrast to the region of the upper 2004 that includes the portion. Thus, selective modification of the characteristics of different areas of the upper using the overlay portion increases the strength in other areas of the upper while maintaining the desired flexibility and low stiffness in some areas of the upper, and It will be appreciated that it helps to reduce stretch resistance.

  An alternative embodiment of a portion of the upper that includes an intermediate buffer layer 2760 and a rigid layer 2710 is shown in FIGS. In this alternative embodiment, the rigid layer 2710 is generally uniform, rigid, and / or resistant to selective material properties provided by the embodiments shown in FIGS. Or have strength. As shown in FIG. 34, the force 2708 applied to the rigid upper 2710 may be partially transmitted to the intermediate buffer layer 2760. However, due to the relative flexibility of the rigid upper 2710, some force 2708 is also transmitted along the region 2711 of the rigid upper 2710 around the intermediate buffer layer 2760. As a result, since only a part of the force 2708 is absorbed by the intermediate buffer layer 2760, the buffering effect is reduced, and the remaining force 2708 is transmitted to another place of the rigid upper 2710.
