Abstract
Description
Technical Field
[0001] [Cross - Reference to Related Applications] This application claims the benefit of priority of U.S. Provisional Application No. 342,289, filed on May 16, 2022, entitled "Fixing System for Articles", the entire disclosure of which is incorporated herein by reference.
[0002] [Reference to Federally Sponsored Research and Development] Not applicable
[0003] [Sequence Listing] Not applicable
[0004] The present disclosure generally relates to a fixing system for articles, and more specifically to an article comprising a fixing system including a fixing member and a plurality of fixing elements.
Background Art
[0005] Many conventional shoes or other footwear items generally have an upper and a sole attached to the lower end of the upper. Conventional shoes further include an internal space, i.e., a cavity or chamber, formed by the inner surfaces of the upper and the sole, which receives the user's foot before the shoe is secured to the foot. The sole is attached to the lower surface or boundary of the upper and is positioned between the upper and the ground. As a result, the sole typically provides stability and cushioning to the user when wearing the shoe. In some examples, the sole may include multiple components such as an outsole, a midsole, a top portion, etc. The outsole can provide traction to the bottom surface of the sole, and the midsole is attached to the inner surface of the outsole and may provide cushioning or additional stability to the sole. For example, the sole can include a specific foam material that can enhance stability at one or more desired positions along the sole, or a foam material that can reduce the stress and impact energy applied to the foot and leg when the user runs, walks, or engages in other activities. Additionally, the sole may include additional components such as a plate embedded in the sole to increase the overall rigidity of the sole and reduce energy loss during use.
[0006] The upper generally extends upward from the sole and defines an internal cavity that completely or partially encloses the foot. In many cases, the upper extends across the instep and toe regions, as well as the inner and outer sides. Also, many footwear items may include a tongue that extends across the instep region to fill the gap between the edges of the inner and outer sides of the upper and defines an opening into the cavity. Additionally, the tongue may be positioned between the inner and outer sides of the upper below the lacing system so that the tightening of the shoe can be adjusted. The tongue may further be made operable by the user to allow the foot to be inserted into and removed from the internal space or cavity. Further, a fastening system allows the user to adjust the dimensions of the upper or the sole, whereby the upper can accommodate various types of feet with different sizes and shapes.
[0007] Many shoe uppers can be composed of a variety of materials, which are utilized to form the upper and may be selected for use based on one or more intended uses of the shoe. Also, the upper may include portions that contain various materials specialized for specific regions of the upper. For example, in regions adjacent to the front or heel areas of the upper, it may be desirable to add stability to provide higher resistance and rigidity. In contrast, other parts of the shoe may include a soft woven fabric to provide stretch resistance, flexibility, breathability, or moisture absorption and dissipation properties.
[0008] Similarly, other articles such as clothing generally include a fastening system for opening and closing a part of the clothing. For example, conventional clothing such as a pair of trousers or shorts can include one or more fly sections along the waistband, and the outer flap of the fly section is fastened to the inner flap by one or more of buttons and zippers disposed on one or both of the inner and outer flaps.

Mode for Carrying Out the Invention
[0016] The following discussion and several aspects of the accompanying drawings disclose various embodiments or configurations of an article of footwear or an article such as a shoe and a sole structure. Embodiments of the shoe or sole structure are disclosed with reference to sports shoes such as running shoes, tennis shoes, basketball shoes, etc., but the concepts related to embodiments of the shoe or sole structure can be applied to a wide range of footwear and footwear styles such as, for example, cross-training shoes, football shoes, golf shoes, hiking shoes, hiking boots, ski and snowboard boots, soccer shoes and cleats, walking shoes, track cleats, etc. The concepts of the shoe or sole structure can also be applied to footwear articles that are intended for non-competitive use, such as dress shoes, sandals, loafers, slippers, heels, etc. In addition to footwear, the specific concepts described herein can also be applied to and incorporated into other types of clothing items or other sports equipment including helmets, pads or protective pads, shin guards, and gloves. Further, the specific concepts described herein can be incorporated into cushions, backpack straps, golf clubs, or other consumer or industrial products. Accordingly, the concepts described herein can be utilized in a variety of products.
[0017] As used herein, the term "about" refers to variations in numerical quantities that can occur, for example, through typical measurement and manufacturing procedures used in an article of footwear or other manufactured article that may include embodiments of the disclosure herein, through inadvertent error in these procedures, through differences in the manufacture, source, or purity of the components used to make or carry out the methods for making a composition or mixture, etc. Throughout the present disclosure, the terms "about" and "approximately" refer to a range of values of ±5% of the value of the numerical term that they precede.
[0018] As used herein, the term "elastomer" refers to the elastic properties of a material, such as a polymer, or properties such as those of rubber. For example, the term "elastomeric material" is intended to refer to a material configured to elastically deform when a load is applied to the material and return to its original shape when the load is removed from the material. Thus, the first material may have elastomeric properties, or may be configured to have a first elasticity that is greater than or less than that of a second material, whether or not the second material has elastomeric properties, or may be configured to have a certain second elasticity.
[0019] Further, as used herein, unless otherwise specifically defined or limited, terms regarding directions are used for the convenience of reference for discussing a particular figure or example. For example, references to "downward" or other directions, or "down" or other positions, may be used to discuss a particular example or aspect of a drawing, but do not necessarily require the same directions or arrangements in all installations or configurations. Terms such as first, second, third, etc. as used herein may be used to describe various elements, components, regions, layers, and / or sections. These elements, components, regions, layers, and / or sections should not be limited by these terms. These terms can only be used to distinguish one element, component, region, layer, or section from another region, layer, or section. Terms such as "first", "second", etc. and other ordinal numbers do not mean order or sequence unless clearly indicated by the context. Thus, a first element, component, region, layer, or section described below can be referred to as a second element, component, region, layer, or section without departing from the teachings of the exemplary configuration.
[0020] Aspects of the present disclosure are directed to footwear articles and / or particular components of footwear, such as uppers and / or soles or sole structures. The upper may be composed of knit parts, woven fabrics, and / or non-woven fabrics. The knit parts can be manufactured by knitting of yarns, the woven textile can be manufactured by weaving of yarns, and the non-woven textile can be manufactured by production of an integral non-woven web. Knit fabrics include fabrics formed by warp knitting, weft knitting, plain knitting, circular knitting, and / or other suitable knitting operations. The knit fabric can have, for example, a plain knit structure, a mesh knit structure, and / or a rib knit structure. Woven textiles include textiles formed by any of a number of weaving forms, such as plain weave, twill weave, satin weave, dobby weave, jacquard weave, double weave, and / or double cloth weave, but are not limited thereto. Non-woven textiles include textiles made, for example, by the airlaid method and / or the spunlaid method. The upper may be composed of various materials such as a first yarn, a second yarn, and / or a third yarn, which may have various properties or various visual properties.
[0021] The following discussion and the accompanying FIGS. 1-13 disclose various embodiments or configurations of a footwear article. The footwear article can be provided as a pair of shoes including a first shoe or left shoe and a second shoe or right shoe. The left and right shoes may be similar in all material aspects except that the left and right shoes are sized and shaped such that the left shoe and the right shoe receive the user's left and right feet, respectively. For ease of disclosure, a single shoe or footwear article is referred to in order to describe aspects of the present disclosure. In some of the drawings, the footwear article is depicted as a right shoe, and in some of the drawings, the footwear article is depicted as a left shoe. The following disclosure regarding the footwear article is applicable to both the left and right shoes. In some embodiments, there may be differences other than the left / right configuration between the left and right shoes. In some embodiments, the left shoe may include a frame, and the right shoe may not include a frame, or vice versa. Further, in some embodiments, the left shoe may include one or more additional elements not included in the right shoe, or vice versa.
[0022] Referring to FIGS. 1-3, an exemplary embodiment of a footwear article 100 including an upper 102 and a sole structure 104 is shown. The upper 102 is attached to the sole structure 104 and together defines an internal cavity 106 (see FIGS. 2 and 3) into which a foot can be inserted. For reference, the footwear article 100 defines a toe region 108, a midfoot region 110, and a heel region 112 (see FIGS. 2 and 3). The toe region 108 generally corresponds to a portion of the footwear article 100 that encloses a portion of the foot including the toes, the ball of the foot, and the joints connecting the metatarsal and phalangeal bones to the toes or phalanges. The midfoot region 110 is adjacent and proximate to the toe region 108 and generally corresponds to a portion of the footwear article 100 that encloses the arch of the foot along with the bridge of the foot. The heel region 112 is adjacent and proximate to the midfoot region 110 and generally corresponds to a portion of the footwear article 100 that encloses the rear portion of the foot including the heel or calcaneus, the ankle, and / or the Achilles tendon.
[0023] Many conventional footwear uppers are formed from multiple elements (e.g., fabrics, polymer foams, polymer sheets, leather, and synthetic leather) that are joined by adhesion or stitching at seams. In some embodiments, the upper 102 of the footwear article 100 is formed from a knit structure or knit components. In various embodiments, the knit components can incorporate various types of yarns that can provide different properties to the upper. For example, one region of the upper 102 can be formed from a first type of yarn that imparts a first set of properties, and another region of the upper 102 can be formed from a second type of yarn that imparts a second set of properties. Using this configuration, the properties of the upper 102 can be varied across the upper 102 by selecting specific yarns for different regions of the upper 102.
[0024] With respect to the material(s) forming the upper 102, the specific properties imparted to a region of the knit component by a particular type of yarn can at least partially depend on the materials forming the various filaments and fibers of the yarn. For example, cotton can impart a soft effect, biodegradability, or a natural aesthetic to a knit material. Elastane and stretch polyester each impart a desired stretchability and recoverability to a knit material. Rayon can provide a lustrous and hygroscopic material, wool can provide a material with improved hygroscopicity, nylon can provide a wear-resistant and durable material, and polyester can provide a hydrophobic and durable material.
[0025] Other aspects of the knit component can be varied to affect the properties of the knit component and provide desired properties. For example, the yarns forming the knit component can include monofilament yarns or multifilament yarns, or the yarns can include filaments each formed from two or more different materials. Additionally, the knit component can be formed using a particular knitting process to impart specific properties to regions of the knit component. Thus, both the material forming the yarn and other aspects of the yarn can be selected to impart various properties to specific regions of the upper 102.
[0026] In some embodiments, the elasticity of the knit structure may be measured based on a comparison between the width or length of the knit structure in a first non-stretched state and the width or length of the knit structure in a second stretched state after a force is applied laterally to the knit structure. In further embodiments, the upper 102 may also include additional structural elements. In some embodiments, a heel plate or cover (not shown) may be provided within the heel region 112 to provide additional support to the user's heel. In some embodiments, other elements, such as plastic materials, logos, trademarks, etc., can also be applied and fixed to the outer surface using an adhesive or a thermoforming process. In some embodiments, the properties associated with the upper 102, such as stitch type, thread type, or properties associated with different stitch types or thread types, such as elasticity, aesthetic appearance, thickness, breathability, or scuff resistance, may be varied.
[0027] Referring again to FIG. 1, the sole structure 104 is connected or fixed to the upper 102 and extends between the user's foot and the ground when the footwear article 100 is worn by the user. The sole structure 104 may include one or more components, which may include an outsole, a midsole, a heel, a vamp, and / or an insole. In some embodiments, the sole structure 104 may include an outsole that provides traction to the user and structural integrity to the sole structure, a midsole that provides a cushioning system, and an insole that supports the user's arch. Further, the insole may be a strobel board, a toe board, a lasting board, etc., or a combination thereof, the insole may be provided between the upper 102 and the sole structure 104, or the insole may be provided as part of the upper 102.
[0028] Furthermore, the insole can be disposed within the inner cavity of the upper and can directly contact the user's foot while the footwear article is being worn. Further, the upper 102 can include a liner (not shown) that can enhance comfort, for example, by reducing friction between the user's foot and the upper, insole, sole, etc., and / or by providing moisture absorption and dissipation characteristics. The liner may cover the entire inner cavity or only a part thereof. In some embodiments, a binding (not shown) may surround the opening of the inner cavity to fix the liner to the upper and / or to provide an aesthetic element to the footwear article.
[0029] Referring to FIGS. 2 and 3, the footwear article 100 also defines an outer side surface 116 and an inner side surface 118. When the user is wearing the shoe, the outer side surface 116 corresponds to the portion facing the outside of the footwear article 100, while the inner side surface 118 corresponds to the portion facing the inside of the footwear article 100. Thus, the footwear article 100 has opposing outer and inner side surfaces 116, 118. The outer and inner side surfaces 116, 118 are adjacent to each other along a longitudinal center plane or axis 120 of the footwear article 100 that is coplanar with the longitudinal axis L of FIG. 1. As further discussed herein, the longitudinal center plane or axis 120 can define a central intermediate axis between the outer and inner side surfaces 116, 118 of the footwear article 100. In other words, the longitudinal plane or axis 120 extends between the proximal end 122 at the rear of the footwear article 100 and the distal end 124 at the front of the footwear article 100 and may continuously define the middle of the insole 126, sole structure 104, and / or upper 102 of the footwear article 100. That is, the longitudinal plane or axis 120 is a straight axis that extends from the proximal end 122 at the rear of the heel region 112 to the distal end 124 at the front of the toe region 108.
[0030] Unless otherwise specified, and referring to FIGS. 2 and 3, the footwear article 100 may be defined by a toe region 108, a midfoot region 110, and a heel region 112. The toe region 108 generally corresponds to a portion of the footwear article 100 that encompasses a portion of the foot 128 including the toes or phalanges 130, the ball of the foot 132 of the foot 128, and one or more of the joints 134 that connect the midfoot bone 136 of the foot 128 to the toes or phalanges 130. The midfoot region 110 is adjacent and proximate to the toe region 108. The midfoot region 110 generally corresponds to a portion of the footwear article 100 that encompasses the arch and bridge of the foot 128. The heel region 112 is adjacent and proximate to the midfoot region 110. The heel region 112 generally corresponds to a portion of the footwear article 100 that encompasses the back portion of the foot 128 including the heel or calcaneus 138, the ankle (not shown), and / or the Achilles tendon (not shown).
[0031] Still referring to FIGS. 2 and 3, the toe region 108, the midfoot region 110, the heel region 112, the outer side surface 116, and the inner side surface 118 are intended to define the boundaries or regions of the footwear article 100. To this end, the toe region 108, the midfoot region 110, the heel region 112, the outer side surface 116, and the inner side surface 118 generally characterize the sections of the footwear article 100. Certain aspects of the present disclosure may refer to portions or elements that are coaxial with one or more of the toe region 108, the midfoot region 110, the heel region 112, the outer side surface 116, and / or the inner side surface 118. Further, both the upper 102 and the sole structure 104 may be characterized as referring to portions within the toe region 108, the midfoot region 110, the heel region 112, and / or portions along the outer side surface 116 and / or the inner side surface 118. Accordingly, the upper 102 and the sole structure 104, and / or the individual portions of the upper 102 and the sole structure 104, may include portions disposed within the toe region 108, the midfoot region 110, the heel region 112, and / or portions disposed along the outer side surface 116 and the inner side surface 118.
[0032] Referring still to FIGS. 2 and 3, the toe region 108, the midfoot region 110, the heel region 112, the outer side surface 116, and the inner side surface 118 are shown in detail. The toe region 108 extends from the toe tip 140 to the widest part 142 of the footwear article 100. The widest part 142 is defined or measured along a first line 144 that is perpendicular to the longitudinal axis 120 extending from the distal part of the toe tip 140 to the distal part of the heel end 146 on the opposite side of the toe tip 140. The midfoot region 110 extends from the widest part 142 to the thinnest part 148 of the footwear article 100. The thinnest part 148 of the footwear article 100 is defined as the thinnest part of the footwear article 100 measured across a second line 150 that is perpendicular to the longitudinal axis 120. The heel region 112 extends from the thinnest part 148 to the heel end 146 of the footwear article 100.
[0033] Considering the foregoing description, it should be understood by those skilled in the art that numerous modifications are apparent and that each of the individual components can be incorporated into a number of footwear articles. Accordingly, the side surfaces and components thereof of the footwear article 100 may be described with reference to the general regions or parts of the footwear article 100, but it should be understood that the boundaries of the toe region 108, the midfoot region 110, the heel region 112, the outer side surface 116, and / or the inner side surface 118 described herein may vary between footwear articles. However, the side surfaces and the individual components thereof of the footwear article 100 can also be described with reference to the exact regions or parts of the footwear article 100, and the scope of the claims appended hereto can incorporate limitations related to these boundaries of the toe region 108, the midfoot region 110, the heel region 112, the outer side surface 116, and / or the inner side surface 118 described herein.
[0034] Referring further to FIGS. 2 and 3, the inner side surface 118 begins at the distal toe tip 140 and arches outwardly along the inside of the footwear article 100 from the toe region 108 toward the midfoot region 110. The inner side surface 118 reaches a first line 144, at which point the inner side surface 118 curves inwardly and arches toward the central longitudinal axis 120. The inner side surface 118 extends from the first line 144, i.e., the widest portion 142, toward a second line 150, i.e., the thinnest portion 148, and at that point, i.e., beyond the first line 144, the inner side surface 118 enters the midfoot region 110. When reaching the second line 150, the inner side surface 118 warps outwardly away from the longitudinal central axis 120, and at that point, i.e., when crossing the second line 150, the inner side surface 118 extends into the heel region 112. Thereafter, the inner side surface 118 warps outwardly and then warps inwardly toward the heel end 146, terminating at the point where the inner side surface 118 contacts the longitudinal central axis 120.
[0035] The outer side surface 116 also begins at the distal toe tip 140 and warps outwardly along the outside side surface of the footwear article 100 from the toe region 108 toward the midfoot region 110. The outer side surface 116 reaches a first line 144, at which point the outer side surface 116 curves inwardly and arches toward the longitudinal central axis 120. The outer side surface 116 extends from the first line 144, i.e., the widest portion 142, toward a second line 150, i.e., the thinnest portion 148, and at that point, i.e., when crossing the first line 144, the outer side surface 116 enters the midfoot region 110. When reaching the second line 150, the outer side surface 116 warps outwardly away from the longitudinal central axis 120, and at that point, i.e., when crossing the second line 150, the outer side surface 116 extends into the heel region 112. Thereafter, the outer side surface 116 warps outwardly and then warps inwardly toward the heel end 146, terminating at the point where the outer side surface 116 contacts the longitudinal central axis 120.
[0036] Still referring to FIGS. 2 and 3, the upper 102 extends across the toe region 108, the midfoot region 110, and the heel region 112 along the outer and inner side surfaces 116, 118, and houses and wraps the user's foot. When fully assembled, the upper 102 also includes an inner surface 152 and an outer surface 154. The inner surface 152 faces inward and generally defines the inner cavity 106, and the outer surface 154 of the upper 102 faces outward and generally defines the outer perimeter or boundary of the upper 102. Also, the upper 102 includes an opening 156 that is at least partially located in the heel region 112 of the footwear article 100, and this opening provides access to the inner cavity 106 and allows the foot to be inserted and removed through this opening. In some embodiments, the upper 102 can also include a vamp region 158 that extends from the opening 156 in the heel region 112 to a region proximate the toe region 108 across the region corresponding to the instep. The vamp region 158 can comprise a region similar to the region where the tongue 160 of this embodiment is disposed. In some embodiments, the upper 102 does not include a tongue 160, i.e., the upper 102 is tongue-less.
[0037] In the illustrated embodiment, the sole structure 104 includes a midsole 162 and an outsole 164. The outsole 164 may define the bottom end or bottom surface 166 of the sole structure 104 across the heel region 112, the midfoot region 110, and the toe region 108. Further, the outsole 164 may be the portion of the sole structure 104 that engages the ground, may include the portion that engages the ground, and may be on the opposite side of the insole. As shown in FIG. 1, the bottom surface 166 of the outsole 164 may include a tread pattern 168 that can include various shapes and configurations. The outsole 164 can be formed from one or more materials to impart durability, abrasion resistance, wear resistance, or traction to the sole structure 104. In some embodiments, the outsole 164 may be formed from any type of elastomeric material, such as rubber including thermosetting elastomers or thermoplastic elastomers, or a thermoplastic material, such as thermoplastic polyurethane (TPU). In some embodiments, the outsole 164 can define a Shore A hardness up to 95. Further, the outsole 164 may be manufactured by a process including injection molding, vulcanization, layer-by-layer printing, i.e., an additive manufacturing system or method, etc.
[0038] Referring still to FIG. 1, the midsole 162 can be individually constructed from, for example, a thermoplastic material such as polyurethane (PU), and / or ethylene-vinyl acetate (EVA), its copolymers, or similar types of materials. In other embodiments, the midsole 162 can be an EVA-solid-sponge (“ESS”) material, an EVA foam (e.g., PUMA® ProFoam LiteTM, IGNITE foam), polyurethane, polyether, olefin block copolymer, organosheet, a thermoplastic material (e.g., thermoplastic polyurethane, thermoplastic elastomer, thermoplastic polyolefin, etc.), or a supercritical foam. The midsole 162 can be a single polymer material, or a blend of materials such as an EVA copolymer, thermoplastic polyurethane, polyether block amide (PEBA) copolymer, and / or olefin block copolymer. An example of a PEBA material is PEBAX®. In some embodiments, the midsole 162 is manufactured by a process including injection molding, vulcanization, layer-by-layer printing, i.e., an additive manufacturing system or method, etc.
[0039] In embodiments where the midsole 162 is formed from a supercritical foaming process, the supercritical foam is produced using a process that takes place in an autoclave, an injection molding apparatus, or a sufficiently heated / pressurized vessel that can process a supercritical fluid (e.g., CO2, N2, or a mixture thereof), and preferably a molten material (e.g., TPU, EVA, polyolefin elastomer, or a mixture thereof), and includes a microcellular foam or particulate foam such as TPU, EVA, PEBAX®. During an exemplary process, a solution of the supercritical fluid and the molten material is pumped into a pressurized vessel, after which the pressure within the vessel is released and the molecules of the supercritical fluid rapidly convert to a gas, forming small pockets within the material and causing the material to expand into a foam. In further embodiments, the midsole 162 can be formed using alternative methods known in the art, including the use of an expansion press, an injection molding machine, a pellet expansion process, a cold foaming process, compression molding techniques, die cutting, or any combination thereof. For example, the midsole 162 may include an initial foaming step of foaming a material using a supercritical gas, followed by a step of compression molding or die cutting into a specific shape.

In other words, the plurality of fixing elements 280 are arranged in a row, spaced apart from the fixing member 278, with the first fixing element 280a being closest to the fixing member 278, the third fixing element 280c being farthest from the fixing member 278, and the second fixing element 280b being between the first and third fixing elements 280a, 280c. In some embodiments, the plurality of fixing elements 280 may include two or more than four fixing elements operably connected to the fixing member 278.
[0042] In some embodiments, the plurality of fixing elements 280 may include a plurality of first fixing elements and a plurality of second fixing elements having different characteristics than the plurality of first fixing elements, such as shape, color, and material. In such embodiments, one or more of the plurality of first fixing elements may have different characteristics than the other plurality of first fixing elements and the plurality of second fixing elements. In some embodiments, the plurality of fixing elements 280 may include two or more fixing elements each having different characteristics from one another. In some embodiments, one or more of the plurality of fixing elements 280 may be disposed from a first side of the fixing member 278, and one or more of the plurality of fixing elements 280 may be disposed from a second side opposite the first side of the fixing member 278.
[0043] Referring specifically to FIG. 6 here, the fixing member 278 of the fixing mechanism 272 is shown in more detail. The fixing member 278 has a first or inner end 290, a second or outer end 292 opposite the inner end 290, and a fixing member shaft 294 extending through the inner and outer ends 290, 292. Further, the fixing member 278 has a first or inner portion 296 extending from the inner end 290 towards the outer end 292, a second or outer portion 298 extending from the outer end 292 towards the inner end 290, and a third or central portion 300 extending between the inner and outer portions 296, 298. The fixing protrusion 302 extends outwardly from the outer portion 298 and is configured such that a user can grasp and rotate the fixing member 278 about the fixing member shaft 294 in a first direction 304 or a second direction 306 opposite the first direction 304. The inner portion 296 has a first outer circumference 308 having a first geometric shape, and the outer portion 298 has a second outer circumference 310 having a second geometric shape. In the illustrated embodiment, the first and second geometric shapes of the first and second outer circumferences 308, 310 of the inner and outer portions 296, 298 of the fixing member 278 have a similar circular shape. In some embodiments, the first geometric shape of the first outer circumference 308 may be different from the second geometric shape of the second outer circumference 310 of the fixing member 278.
[0044] Continuing to refer to FIG. 6, in the illustrated embodiment, the fixing member 278 includes a first opening 312 extending into the central portion 300 towards the first or upper circumferential side surface 314, and a second opening 316 extending into the central portion 300 near the second or lower circumferential side surface 318 of the fixing member 278. As will be discussed in more detail below, in some embodiments, the first and second openings 312, 316 of the fixing member 278 can be connected to form an internal connection opening or internal passage 320 of the fixing member 278. In some embodiments, the first and second openings 312, 316 may extend only partially into the central portion 300 of the fixing member 278.
[0045] The fixing member 278 is intended to be configured such that the outer side and the central portions 298, 300 can rotate relative to the inner portion 296 and / or relative to each other. For example, referring again to FIG. 6, the inner portion 296 can include a coupling protrusion 322 that extends upward along the fixing member axis 294, and this coupling protrusion can be received within a coupling recess 324 of the central portion 300 that is aligned with and configured to receive the coupling protrusion of the inner portion 296. In such an embodiment, when the user rotates the fixing protrusion 302 of the outer portion 298 in the first direction 304, the central and outer portions 298, 300 rotate in the first direction 304 while the inner portion 296 remains stationary. In other embodiments, other known structures can be included on and / or within the fixing member 278 to enable the outer portion 298 to be rotatable at least relative to the inner portion 296. For example, in some embodiments, the fixing member 278 can include an outer lip (not shown) that is disposed along the central portion 300 and can be received slidably within an inner channel (not shown) of the inner portion 296 of the fixing member 278.

[0047] Referring further to FIG. 7, the inner portion 338 has a first outer periphery 344 having a first geometric shape, and the outer portion 340 has a second outer periphery 346 having a second geometric shape. In the illustrated embodiment, the first and second geometric shapes of the first and second outer peripheries 344, 346 of the inner and outer portions 338, 340, respectively, of the fixing element 280 are each formed as an elongated rhombus in which two opposing points are aligned along the longitudinal axis 348 of the fixing element. In some embodiments, the first geometric shape of the first outer periphery 344 of the inner portion 338 may be different from the second geometric shape of the second outer periphery 346 of the outer portion 340. In some embodiments, the first outer periphery 344 of the inner portion 338 may be circular, while the second outer periphery 346 of the outer portion 340 may be triangular. In some embodiments, the first geometric shape of the first outer periphery 344 may be non-polygonal, while the second geometric shape of the second outer periphery 346 may be polygonal, or vice versa. In some embodiments, the second outer periphery 346 of the outer portion 340 can have a regular or irregular polygonal shape, such as, for example, a triangular, square, pentagonal, hexagonal, or octagonal shape.
[0048] Continuing to refer to FIG. 7, the fixed element 280 has a first longitudinal side surface 350 and a second longitudinal side surface 352 opposite the first longitudinal side surface 350, and the longitudinal axis 348 of the fixed element extends through the first and second longitudinal side surfaces 350, 352.

Further, the inner portions 296 of the fixing member 278 and the inner portions 338 of the plurality of fixing elements 280 are disposed within the channel section 384, while the central portion 300 of the fixing member 278 and the central portions 342 of the plurality of fixing elements 280 are adjacent to the channel opening 386. In the illustrated embodiment, each of the fixing member 278 and the plurality of fixing elements 280 is rotatably mounted to the inner layer 388 along the channel section 384 such that the fixing member 278 is rotatable within the channel 274 about the fixing member axis 294 and the plurality of fixing elements 280 are each rotatable within the channel 274 about the fixing element axis 336. In some embodiments, the fixing system 270 can be configured such that one or more of the plurality of fixing elements 280 are slidable within the channel section 384 along the inner layer 388 and toward one or both of the proximal end 392 and the distal end 394 of the channel 274 along the channel axis 396. In some such embodiments, one or more of the plurality of fixing elements 280 can be rotatable about the fixed axis 336 and slidable along the channel axis 396.
[0060] Referring now to FIGS. 9 and 10, the fastening system 270 of the footwear article 200 is configured to transition between an initial or relaxed configuration in which the wire 380 has a first tension (as shown in FIG. 9), and a tightened configuration in which the wire 380 has a second tension greater than the first tension (as shown in FIG. 10). More specifically, in the illustrated embodiment, the plurality of fastening elements 280 are rotated simultaneously about the fastening element axis 336 (see FIG. 8) between a first or relaxed position (as shown in FIG. 9) and a second or tightened position (as shown in FIG. 10) via rotation of the fastening member 278 about the fastening member axis 294 (see FIG. 8) in the first or second directions 304, 306.
[0061] As discussed herein, the fastening system 270 is configured such that the geometry of the plurality of openings 276 of the channel 274 generally resembles the geometry of at least the second outer perimeter 346 of the plurality of fastening elements 280 and the second outer perimeter 310 of the fastening member 278. Thus, when the fastening system 270 is in the relaxed configuration (as shown in FIG. 9), the plurality of fastening elements 280 are in a relaxed position in which the longitudinal axis 348 of the plurality of fastening elements 280 is substantially parallel to the channel longitudinal axis 396. With the plurality of fastening elements 280 in the relaxed position (as shown in FIG. 9), the second outer perimeters 346 of the first, second, and third fastening elements 280a, 280b, 280c are aligned with the second, third, and fourth openings 276b, 276c, 276d of the channel opening 386, respectively, such that at least the outer portions 340 of the first, second, and third fastening elements 280a, 280b, 280c can move within the second, third, and fourth openings 276b, 276c, 276d, respectively.
[0062] In the illustrated embodiments of FIGS. 4-10, the securing system 270 is movable between a loosened configuration (as shown in FIG. 9) and a tightened configuration (as shown in FIG. 10) by rotation of the securing member 278 in a first direction 304. In particular, when the securing member 278 is rotated in the first direction 304 about the securing member axis 294, the plurality of securing elements 280 simultaneously rotate in the first direction 304 from a loosened position (as shown in FIG. 9) to a tightened position where the longitudinal axis 348 of the plurality of securing elements 280 is substantially perpendicular to the channel longitudinal axis 396 (as shown in FIG. 10). As the securing member 278 rotates in the first direction 304, the first opening 312 of the securing member 278 rotates towards the first securing element 280a while the second opening 316 rotates away from the first securing element 280a, such that the plurality of securing elements 280 are pulled and rotated by the wire 380 at the first opening 354.
[0063] More specifically, the first securing element 280a is pulled by the wire 380 at the first opening 354, whereby the first securing element 280a rotates about the securing element axis 336 in the first direction 304 towards the tightened position. As the first securing element 280a rotates in the first direction 304, the wire 380 connected to or within both the third opening 362 of the first securing element 280a and the first opening 354 of the second securing element 280b further rotates the second securing element 280b in the first direction 304 towards the tightened position. As the second securing element 280b rotates in the first direction 304, the wire 380 connected to or within both the third opening 362 of the second securing element 280b and the first opening 354 of the third securing element 280c further rotates the third securing element 280c in the first direction 304 towards the tightened position.
[0064] Specifically, referring to FIG. 10, when a plurality of fixing elements 280 are in the tightened position (as shown in FIG. 10) and at least the outer portion 346 is received within the plurality of openings 276, the second outer circumference 346 of the outer portion 340 of the first, second, and third fixing elements 340 is offset from the second, third, and fourth openings 276b, 276c, 276d of the channel opening 386, respectively. For this reason, at least the outer portions 340 of the first, second, and third fixing elements 280a, 280b, 280c cannot move within the second, third, and fourth openings 276b, 276c, 276d, respectively. Further, the inner surfaces (see FIG. 8) of the outer portions 340 of the first, second, and third fixing elements 280a, 280b, 280c in the tightened position contact the outer surface 254 of the upper 202 adjacent to the corresponding second, third, and fourth openings 276b, 276c, 276d. Further, when the plurality of fixing elements 280 are in the tightened position, the wire 380 is at least partially wound around the central portion 300 of the fixing member 278 and the central portions 342 of the plurality of fixing elements 280, and thus has a second tension. Since the wire 380 has the second tension, the plurality of fixing elements 280 rotatably attached to the fixing mechanism 272 and the inner layer 388 of the upper 202 (see FIG. 8) pull the outer side surface 216 and the inner side surface 218 of the upper 202 inward toward the channel 274, and further pull the upper region 258 downward toward the sole structure 204 (see FIG. 4).
[0065] Furthermore, when the fixing system 270 is in a tightened configuration, the plurality of fixing elements 280 are pulled towards the fixing member 278 along the longitudinal channel axis 396 by a wire 380 having a second tension. For example, as shown in FIG. 9, when the fixing system 270 is in a loosened configuration and the wire 380 has a first tension, the fixing mechanism 272 has a first overall length L1 measured from the fixing element longitudinal axis 348 of the third fixing element 280c to the fixing member axis 294 of the fixing member 278. As shown in FIG. 10, when the fixing system 270 is in a tightened configuration and the wire 380 has a second tension, since the wire 380 pulls each of the plurality of fixing elements 280 towards the fixing member 278, the fixing mechanism 272 has a second overall length L2 that is smaller than the first overall length L1. The fixing mechanism 272 has the second overall length L2, and when the plurality of fixing elements 280 are attached to the inner surface 252 of the upper 202, the upper 202 is further tightened around the user's foot disposed within the internal cavity 206 of the upper 202 (see FIG. 4).
[0066] At least the fixing member 278 of the fixing mechanism 272 can hold the plurality of fixing elements 280 in a tightened position (as shown in FIG. 10) so as to be releasable, and thus it is contemplated that a fixing holding mechanism (not shown) configured to hold the fixing system 270 in a tightened configuration may be included. In some embodiments, the fixing holding mechanism can be disposed between the inner and central portions 296, 300 of the fixing member 278, and at least the central portion 300 can be configured to hold it in a position releasable with respect to the inner portion 296 and / or the inner layer 388 of the upper 202 along the channel partition 384. In other embodiments, a tension holding mechanism can be disposed along a part of the channel partition 384 of the channel 274 and the first outer periphery 308 of the inner portion 296 of the fixing member 278, and the tension holding mechanism can be configured to hold the entire fixing member 278 in a position releasable with respect to the inner layer 388 of the upper 202 along the channel partition 384.
[0067] In some embodiments, the tension holding mechanism may be a ratchet system that includes a plurality of teeth disposed along an upper surface of an inner portion 296 adjacent to the central portion 300, and one or more pivoting claws disposed on an inner surface of the central portion 300 configured to releasably engage the plurality of teeth of the inner portion 296 of the fixing member 278, or vice versa. In such embodiments, one or more pivoting claws of the ratchet system can pivot via a lever or button (not shown) disposed on the outer portion 298 of the fixing member 278 or elsewhere along the upper 202 of the footwear article 200, and / or via a fixing protrusion 302. In some embodiments, the fixing system 270 can be configured such that one or both of the fixing member 278 and the plurality of fixing members 280 are biased towards a loosened position or a tightened position, for example by a spring.
[0068] Referring again to FIGS. 9 and 10, the fixing system 270 is movable to return from a tightened configuration (as shown in FIG. 10) to a loosened configuration (as shown in FIG. 9) by rotation of the fixing member 278 in a second direction 306. When the fixing member 278 rotates in the second direction 306, each of the plurality of fixing elements 280 is simultaneously rotated in the second direction 306 from a tightened position (as shown in FIG. 10) to a loosened position (as shown in FIG. 9). In some embodiments, the fixing mechanism 272 can be configured to rotate the fixing member 278 about the fixing member axis 294 from a first or initial position up to about 45 degrees in a first direction 304 (as shown in FIG. 9), thereby moving the fixing system 270 from a loosened configuration in which the wire 380 has a first tension to a first tightened configuration in which the wire 380 has a second tension greater than the first tension. In such embodiments, with the fixing member 278 in the first tightened configuration, by further rotating the fixing member 278 about the fixing member axis 294 from the first position up to about 90 degrees in the first direction 304, the fixing system 270 can be moved from the first tightened configuration to a second tightened configuration in which the wire 380 has a third tension greater than the first and second tensions. In some embodiments, the fixing mechanism 272 can be configured to have at least three tightened configurations.
[0069] The fastening system 270 of the footwear article 200 is intended to be configured to automatically transition between a loosened configuration and a fastened configuration in addition to, or instead of, rotation of the fastening member 278 by the user, via one or more user inputs. For example, in some embodiments, the fastening system 270 can include an electric actuator (not shown) configured to transition the fastening system 270 between a loosened configuration and a fastened configuration, and a controller (not shown) configured to control the electric actuator. In some such embodiments, the controller of the fastening system 270 can be configured to control the electric actuator based on one or more user inputs received by the controller, such as pressing a button, swiping, or an electronic input from a wireless device in wireless communication with the controller.
[0070] In such embodiments, a pair of footwear including the footwear article 200 with the fastening system 270 can be simultaneously transitioned between a loosened configuration and a fastened configuration via a user input on a single wireless device simultaneously received by the respective controllers of the pair of footwear. In some such embodiments, the fastening system 270 can further include one or more sensors (not shown) configurable to sense when the user's foot is inserted into the inner cavity 206 of the upper 202, such as a proximity sensor or a pressure sensor, and the controller can be configured to automatically command the electric actuator to transition the fastening mechanism 272 from a loosened configuration to a fastened configuration in response to a signal received from one or more sensors indicating the presence of the user's foot.
[0071] In some such embodiments, the controller of the securing system 270 may be further configured to command an electric actuator to move the securing mechanism 272 from a relaxed configuration to one of a plurality of tightened configurations in response to one or more user inputs corresponding to incremental levels of tightening of the footwear article 200. In some such embodiments, the securing system 270 may further include a battery (not shown) configured to supply power to the controller and the electric actuator. In some such embodiments, the battery of the securing system 270 can be disposed at least partially within the sole structure 204, or may be disposed along the upper 202, such as on the proximal end 222 (see FIG. 4) of the upper 202 for example.
[0072] In some embodiments, the securing member 278 can be configured as an electric actuator (not shown) of the securing system 270. In other embodiments, the electric actuator of the securing system 270 may include an electric motor and a gear system (not shown). In such embodiments, the gear system can be mechanically coupled to at least the securing member 278, and the motor can be configured to rotate the securing member 278 in a first or second direction 304, 306 via the gear system. In some embodiments, the gear system of the securing system 270 can be configured to hold the securing member 278 in at least a tightened position. In such embodiments, the gear system and motor of the securing system 270 may be configured to allow rotation of the securing member 278 by the user, in addition to, or in place of, a user input received by the controller.
[0073] In some embodiments, the securing system 270 can further include one or more lighting elements (not shown), such as light emitting diodes (LEDs), and the controller can be further configured to control the one or more lighting elements to provide a visual indication that can correspond to one or more characteristics of the securing system 270, such as the current tightening level of the securing mechanism 272 or the battery level of the battery, or one or more dynamic characteristics of the footwear article 200. In such embodiments, the one or more lighting elements can be disposed on the securing member 278 and / or on one or more of the plurality of securing elements 280 such that the one or more lighting elements are visible from the outside of the footwear article 200, including the user wearing the footwear 200. For example, in such embodiments, at least the outer portion 298 of the securing member 278 and / or the outer portion 340 of the securing element 280 can include a translucent or transparent material, and the one or more lighting elements of the securing system 270 can be disposed within the securing member 278 and / or the securing element 280.
[0074] It is further contemplated that the connection element 282 of the fixing mechanism 272 of the fixing system 270 may have other configurations or structures. In some embodiments, the connection element 282 of the fixing mechanism 272 may be an interconnected substrate disposed on the inner layer 388 of the upper 202 along the channel section 384 (see FIG. 8), to which a plurality of fixing elements 280 and the fixing member 278 are attached. In such embodiments, the substrate can be configured such that each of the fixing member 278 and the plurality of fixing elements 280 is connected to a corresponding substrate portion. The plurality of substrate portions may be configured such that they do not contact each other when the plurality of fixing elements 280 are in a loosened position (as shown in FIG. 9), and contact each other to provide tension along the upper 202 (see FIG. 4) when the plurality of fixing elements 280 are rotated to a tightened position via rotation of the fixing member 278 (as shown in FIG. 10). In some embodiments, the interconnected substrate may include a material having elastomeric properties. In some embodiments, at least a portion of the inner layer 388 of the upper 202 may be the interconnected substrate. In some embodiments, the upper 202 can be configured such that the interconnected substrate is visible from the outside of the footwear article 200. For example, in such embodiments, at least a portion of the outer layer 390 of the upper 202 adjacent to the channel opening 386 of the channel 274 (see FIG. 8) may include a material having translucent or transparent properties.
[0075] It is further contemplated that the fastening system 270 of the footwear article 200 can include a plurality of fastening mechanisms disposed at various locations on the upper 202. For example, referring again to FIG. 4, the fastening system 270 of the footwear article 200 can include, for example, a first channel and a first fastening mechanism disposed on the outer side surface 216 of the upper 202, similar to the fastening mechanism 272 disposed within the channel 274, and a second channel and a second fastening mechanism disposed on the inner side surface (not shown) of the upper 202, configured similarly to the first channel and the first fastening mechanism. In such an embodiment, with both the first and second fastening mechanisms in a tightened configuration, the upper region 258 of the upper 202 is symmetrically pulled downwardly towards the sole structure 204 from the outer side surface 216 and the inner side surface (not shown).
[0076] It is further contemplated that the fastening system 270 of the footwear article 200 can include one or more support elements, such as, for example, straps, laces, or wings, that are extendable from the sole structure 204 to the fastening mechanism 272. For example, in some embodiments, a first or lateral support element can extend from the sole structure 204 along the outer side surface 216 of the upper 202 to the channel 274, and a second or inner support element can extend from the sole structure 204 across the upper region 258 along the inner side surface (not shown) of the upper 202 to the channel 274. In such an embodiment, the first and second support elements can be connected to the fastening mechanism 272 such that, when the fastening system 270 is in a tightened configuration, at least the second support element is pulled across the upper region 258 towards the outer side surface 216 of the sole structure 204, providing support along the upper region 258. In other embodiments, one or more support elements of the fastening system 270 can be coupled to a plurality of fastening elements 280 such that, when the fastening mechanism 272 is in a tightened configuration, the one or more support elements are directly pulled by the plurality of fastening elements 280.
[0077] The fastening system 270 of the footwear article 200 is further intended to be implementable on the upper 202 to fasten or release the tongue of the upper 202. In this regard, FIGS. 11-13 show another exemplary embodiment of a footwear article 200' having a fastening system 270' and an upper 202', the upper 202' including a tongue 360 extending along the upper region 258 of the upper 202' between the outer and inner side surfaces 216, 218 of the upper 202'. In the illustrated embodiment, the fastening system 270' is configured to be movable between a relaxed configuration in which the tongue 360 is movable away from the sole structure 204 (see FIG. 4) (as shown in FIGS. 11 and 12), and a tightened configuration in which the tongue 360 is pulled inwardly towards the sole structure 204 (see FIG. 4) and held against the upper 202'. In particular, a first or lateral fastening mechanism 272a is disposed on the lateral side surface 216 of the upper 202' adjacent to the first or lateral side surface 360a of the tongue 360, and a second or inner fastening mechanism 272b is disposed on the inner side surface 218 of the inner side surface. Referring particularly to FIG. 11, the lateral fastening mechanism 272a includes a first or lateral fastening member 278a disposed along the lateral side surface 216 of the upper 202' adjacent to both the opening 256 of the upper 202' and the third or upper end 360c of the tongue 360. The lateral fastening mechanism 272a further includes a first or lateral plurality of fastening elements 281a extending from the lateral fastening member 278a adjacent to the outer side surface 360a of the tongue 360 towards the distal end 224 (see FIG. 4) of the upper 202' along the first fastening mechanism longitudinal axis 396a (see FIG. 12). Similarly, the inner fastening mechanism 272b includes a second or inner fastening member 278b disposed along the inner side surface 218 of the upper 202' adjacent to both the opening 256 of the upper 202' and the upper end 360c of the tongue 360. The inner fastening mechanism 272b further includes a second or inner plurality of fastening elements 281b extending from the inner fastening member 278b adjacent to the inner side surface 360b of the tongue 360 towards the distal end 224 (see FIG. 4) of the upper 202' along a second fastening mechanism longitudinal axis (not shown).
[0078] Referring still to FIG. 11, the tongs 360 define both a first or lateral plurality of openings 276a disposed adjacent the outer side surface 360a and a second or inner plurality of openings 276b disposed adjacent the inner side surface 360b. In other words, the outer side surface 360a of the tongs 360 and the outer side surface 216 of the upper 202' form a first or lateral channel 274a of the fixing system 270', and the inner side surface 360b of the tongs 360 and the inner side surface 218 of the upper 202a form a second or inner channel 274b of the fixing system 270'. The lateral and inner channels 274a, 274b include an inner portion (not shown) formed by the upper 202', for example, between the inner and outer surfaces of the upper 202', and an outer portion (not shown) formed by the tongs 360, for example, the outer surface of the tongs 360 along the outer and inner side surfaces 360a, 360b. Accordingly, the outer and inner pluralities of openings 276a, 276b are disposed on the outer portions (not shown) of the corresponding outer and inner channels 274a, 274b, while the outer and inner fixing mechanisms 272a, 272b are disposed on or within the inner portions of the corresponding outer and inner channels 274a, 274b.
[0079] Referring particularly to FIG. 12, when the outer and inner fixing mechanisms 272a, 272b are in a first or unfastened position (as shown in FIGS. 11 and 12), and thus the fixing system 270' is in a loosened configuration, the lateral and inner pluralities of openings 276a, 276b of the tongs 360 are each receivable by the outer and inner pluralities of fixing elements 281a, 281b of the outer and inner fixing mechanisms 272a, 272b, but are not engaged. Accordingly, in the loosened configuration of the fixing system 270' (as shown in FIG. 12), the tongs 360 are freely movable or rotatable relative to the upper 202' so as to be separated from the opening 256 of the upper 202' or the sole structure 204 (see FIG. 4), whereby the outer and inner pluralities of openings 276a, 276b of the tongs 360 can completely disengage from the engagement with the outer and inner pluralities of fixing elements 281a, 281b.
[0080] Referring now to FIG. 13, when a plurality of outer and inner fixing elements 281a, 281b of the outer and inner fixing mechanisms 272a, 272b are received within corresponding outer and inner openings 276a, 276b of the tongue 360, the fixing system 270' can be transitioned to a tightened configuration by rotating the plurality of outer and inner fixing elements 281a, 281b to a second or tightened position (as shown in FIG. 13). In a state where the plurality of outer and inner fixing elements 281a, 281b are in the tightened position, the plurality of outer and inner fixing elements 281a, 281b engage corresponding outer and inner openings 276a, 276b such that the tongue 360 is pulled downwardly toward the sole structure 204 (see FIG. 4) of the footwear article 200 and is fixed or held to the upper 202' adjacent to the opening 256 of the upper 202'.
[0081] In some embodiments, the fixing system 270' can be configured to be movable between a position where the plurality of outer and inner fixing elements 281a, 281b are not tightened and a tightened position by rotation of a single fixing member operatively connected to both the plurality of outer and inner fixing elements 281a, 281b via two or more connecting elements. For example, in some such embodiments, the single fixing member can be disposed on the upper 202', for example, on one of its outer side surface 216, inner side surface 218, proximal end 222, or distal end 224 (see FIG. 4), and operatively connected to each of the plurality of outer and inner fixing elements 281a, 281b. In some embodiments, one or both of the outer and inner fixing mechanisms 272a, 272b can be disposed on the tongue 360, for example, on the lower side of the tongue 360, and one or both of the plurality of outer and inner openings 276a, 276b can be defined on the outer and inner side surfaces 216, 218 of the upper 202', respectively.
[0082] It is further contemplated that the securing system 270' of the footwear article 200' can further include one or more support elements, such as straps or laces, the one or more support elements extending across the topline region 258 of the upper 202' and into each of the first and second channels, and coupling with each of the first and second securing mechanisms, such that when at least one of the first and second securing mechanisms is in a tightened configuration, the first and second securing mechanisms can be pulled towards each other by the one or more support elements. In some embodiments, the one or more support elements can extend along the outer surface 254 of the upper 202' across the topline region 258. In some embodiments, the one or more support elements can extend across the tongue 360 of the upper 202' between the first and second securing mechanisms. In some embodiments, the one or more support elements can include a first support element extending from the outer side surface 216 of the sole structure 204 to the first securing mechanism and a second support element extending from an inner side surface (not shown) of the sole structure 204 to the second securing mechanism. In some such embodiments, the one or more support elements can further include a third support element extending across the topline region 258 of the upper 202', which third support element may or may not be coupled to one or both of the first and second support elements.
[0083] Referring to FIGS. 4 - 13, various components of exemplary footwear articles 200, 200' that include one or more components or structures of the fastening systems 270, 270' can be formed by additive manufacturing techniques such as 3D printing. To that end, a number of 3D printing techniques such as vat photopolymerization, material jetting, binder jetting, powder bed fusion, material extrusion, directed energy deposition, and / or sheet lamination may be implemented to form the footwear article 200 having the fastening system 270. In some embodiments, the fastening mechanism 272 can be 3D printed as a single integral piece. In other embodiments, at least the inner portions 296, 338 of the fastening member 278 or the plurality of fastening elements 280 can be 3D printed within the channel sections 384 of the uppers 202, 202' separately from the outer or central portions 298, 300, 340, 342 and later joined. In some embodiments, one or more portions of the fastening member 278 or the plurality of fastening elements 280 can be 3D printed with a first material and other portions of the fastening member 278 or the plurality of fastening elements 280 can be 3D printed with a second material.
[0084] Aspects of the fastening systems 270, 270' are intended to be incorporated into articles other than the footwear articles 200, 200', such as, for example, clothing, gloves, bags. Referring now to FIGS. 14 and 15, an exemplary embodiment of an article 400 that includes a fastening system 470 having a fastening mechanism 472 is depicted. The fastening system 470 is similar to the fastening system 270 of the footwear article 200, and like elements are indicated with like reference numerals under the "4xx series" and "5xx series" of reference numerals. For example, the fastening mechanism 472 of the fastening system 470 includes a fastening member 478 that operably engages a plurality of fastening elements 480 via a connection element 482 in a manner similar to the fastening mechanism 272 of the fastening system 270 of FIGS. 4 - 10, which has a fastening member 278, a plurality of fastening elements 280, and a connection element 282.
[0085] The securing system 470 of the article 400 is similar in many aspects to the securing system 270 of the footwear article 200, but also has different aspects. In particular, the securing mechanism 472 of the securing system 470 is disposed on a first securing portion 452 of the securing opening 456 of the article 400 and is configured to be movable between a first or unfastened position (as shown in FIG. 14) and a second or fastened position (as shown in FIG. 15), and engages a plurality of apertures 476 disposed on a second securing portion 454 of the securing opening 456. Accordingly, the securing system 470 is movable between a loosened or unfastened configuration in which the second securing portion 454 is relatively movable with respect to the first securing portion 452 (as shown in FIG. 14), and a secured or fastened configuration in which the second securing portion 454 is secured to the first securing portion 452 to close the securing opening 456 (as shown in FIG. 15).
[0086] Referring to FIG. 14, in the illustrated embodiment, the fixing mechanism 472 of the fixing system 470 is disposed on the first fixing portion 452 such that the fixing member 478 is rotatably attached to the first fixing portion 452 adjacent to both the first or upper end 586a and the first opening end 456a of the first fixing portion 452. A plurality of fixing elements 480 are rotatably attached to the first fixing portion 452 and are arranged in a row spaced apart from the fixing member 478 along a fixing mechanism longitudinal axis 596a extending from the fixing member 470 toward the second or lower end 588a of the first fixing portion 452 opposite the upper end 586a. In the illustrated embodiment, the plurality of fixing elements 480 includes a first or upper fixing element 480a disposed adjacent to the fixing member 478, a second or intermediate fixing element 480b disposed adjacent to the first fixing element 480a, and a third or lower fixing element 480c disposed adjacent to the second fixing element 480b. In other words, the plurality of fixing elements 480 are arranged in series along the first fixing portion 452 from the fixing member 478. In some embodiments, the plurality of fixing elements 480 may include two or four or more fixing elements operatively connected to the fixing member 478. In some embodiments, the plurality of fixing elements 480 can include a first plurality of fixing elements and a second plurality of fixing elements having different characteristics from the first plurality of fixing elements, such as shape, color, and material.
[0087] Referring further to FIG. 14, in the illustrated embodiment, the connection element 482 is a wire 580 that is connected to each of the fixing member 478 and the plurality of fixing elements 480.
