[0002] This application claims the benefit and priority of U.S. Provisional Application No. 63 / 418850, filed October 24, 2022, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to a fastening system for footwear products. Background Technology

[0004] Many traditional shoes or other footwear products typically consist of an upper and a sole attached to the lower end of the upper. Traditional shoes also include an internal space, a gap or cavity formed by the inner surfaces of the upper and sole, which accommodates the user's foot before the shoe is fastened 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. Therefore, when the shoe is worn, the sole typically provides stability and cushioning for the user. In some cases, the sole may include multiple components, such as an outsole, midsole, and toeboard. The outsole may provide adhesion friction to the bottom surface of the sole, and the midsole may be attached to the inner surface of the outsole and may provide cushioning or increase stability to the sole. For example, at one or more desired locations along the sole, the sole may include specific foam materials that can increase stability; or it may include foam materials to reduce stress or impact energy on the foot or leg when the user runs, walks, or performs another activity. The sole may also include additional components (such as plates) embedded in the sole to increase the overall stiffness of the sole and reduce energy loss during use.

[0005] The upper typically extends upwards from the sole, forming an inner cavity that fully or partially encloses the foot. In most cases, the upper extends to the instep and toe areas of the foot, traversing the inner and outer sides of the foot. Many footwear products may also include a tongue that extends across the instep area to bridge the gap between the inner and outer edges of the upper, defining an opening into the cavity. The tongue may also be positioned below the lacing system and between the inner and outer sides of the upper to allow adjustment of the shoe's tightness. The tongue can also be manipulated by the user to allow the foot to enter or exit the internal space or cavity. Furthermore, the lacing system allows the user to adjust certain dimensions of the upper or sole, thus allowing the upper to adapt to various foot shapes and sizes.

[0006] The upper of many shoes can include a variety of materials that can be used to form the upper and are selected based on one or more intended uses of the shoe. The upper can also include sections made of different materials in specific areas. For example, increased stability may be needed in the forefoot or heel area of ​​the upper to provide a higher level of resistance or rigidity. Conversely, other parts of the shoe can include soft woven fabrics to provide areas with tensile strength, flexibility, breathability, or moisture-wicking properties.

[0007] However, in many cases, people expect footwear uppers to offer greater comfort and a better fit, as well as improved closure mechanisms. Utility Model Content

[0008] Footwear products as described herein can have various constructions. Footwear products can have an upper and a sole structure attached to the upper.

[0009] In one embodiment, a fastening system for footwear includes a fastening mechanism, shoelaces, and a cable. The fastening mechanism includes a top cover rotatably coupled to a chassis. The shoelaces are configured to be operably connected to the upper of the footwear and the fastening mechanism. The cable is attached to the top cover and configured to rotate about a rotation axis relative to the chassis to adjust the shoe between a loosened configuration and a tightened configuration. The fastening mechanism is tightened by actuating the cable and loosened by rotating the top cover counterclockwise.

[0010] In another embodiment, a fastening system for footwear articles includes a fastening mechanism. The fastening mechanism includes a top cover, a base, a floating latch, a fixed latch, a cable, and a pinion-winding wheel assembly. The shoelaces are configured to operably engage with the upper of the shoe, and the fastening mechanism is configured to be actuated to adjust the shoe from a loose configuration to a tightened configuration.

[0011] In another embodiment, a method of operating a fastening system is described. The steps include: providing a footwear article including an opening configured to receive a foot; providing a fastening mechanism including a first actuation mechanism to adjust the tightness of the shoe; and providing a second actuation mechanism to further adjust the tightness of the shoe. The second actuation mechanism and the first actuation mechanism are configured to operably engage with a pinion-winding wheel assembly. The first actuation mechanism is operably engaged with a spring element, and the spring element adjusts the tension between shoelaces operably connected to the pinion-winding wheel assembly. The pinion-winding wheel assembly rotates in a first direction to adjust the fastening mechanism to a tightened configuration. The pinion-winding wheel assembly rotates in a second direction to adjust the fastening mechanism to a loosened configuration.

[0012] Other aspects of footwear articles, including their features and advantages, will become apparent to those skilled in the art upon reading the accompanying drawings and detailed descriptions herein.

[0027] The following discussion and accompanying figures disclose various embodiments or constructions of shoe and sole structures. While embodiments of shoe or sole structures are disclosed with reference to athletic footwear (e.g., running shoes, tennis shoes, basketball shoes, etc.), the concepts associated with embodiments of shoe or sole structures can be applied to a wide range of footwear and footwear, including, for example, cross-training shoes, soccer shoes, golf shoes, hiking shoes, mountaineering boots, ski and snowboard boots, rugby shoes and spikes, walking shoes and track spikes. The concepts of shoe or sole structures can also be applied to non-athletic footwear articles, including dress shoes, sandals, casual shoes, slippers, and high heels. In addition to shoes, the specific concepts described herein can also be applied to and incorporated into other types of clothing or other sporting equipment, including helmets, padding or protective pads, shin guards, and gloves. Furthermore, the specific concepts described herein can be incorporated into mats, backpack straps, golf clubs, or other consumer or industrial products. Therefore, the concepts described herein can be used in a variety of products.

[0028] As used herein, the term "about" refers to a variation in a numerical quantity that may occur, for example, through typical measurement and manufacturing processes used for footwear or other manufactured articles (which may include embodiments disclosed herein), through unintentional errors in these processes, through differences in the manufacture, origin, or purity of the ingredients used to prepare the composition or mixture or to perform the method. Throughout this disclosure, the terms "about" and "approximately" refer to a range of values ​​within ±5% of the numerical value following the term.

[0029] This disclosure relates to footwear articles and / or specific components of footwear articles, such as uppers and / or soles (or sole structures). Uppers may include knitted components, woven fabrics, and / or nonwoven fabrics. Knitted components may be made from knitted yarns, woven fabrics may be made by knitting yarns, and nonwoven fabrics may be made by creating an integral nonwoven web. Knitted fabrics include fabrics formed by warp knitting, weft knitting, plain knitting, circular knitting, and / or other suitable knitting operations. Knitted fabrics may have, for example, plain knit structures, mesh knit structures, and / or rib knit structures. Woven fabrics include, but are not limited to, fabrics formed by any of a variety of knitting forms, such as plain weave, twill weave, satin weave, dobby weave, jacquard weave, double weave, and / or double weave fabric. Nonwoven fabrics include, for example, fabrics made by air-laid and / or spun web methods. Uppers may include a variety of materials, such as first yarns, second yarns, and / or third yarns, which may have different properties or different visual characteristics.

[0030] Figures 1-3 An exemplary embodiment of footwear article 100 is shown, including an upper 102 and a sole structure 104. The upper 102 is attached to the sole structure 104 and together defines an internal cavity 106 (see...). Figure 2 and Figure 3 The foot can be inserted into the internal cavity 106. For reference, footwear 100 defines a forefoot region 108, a midfoot region 110, and a heel region 112 (see...). Figure 2 and Figure 3 The forefoot region 108 generally corresponds to the portion of the footwear 100 that surrounds the foot, including the toes, the ball of the foot, and the joints connecting the metatarsals to the toes or phalanges. The midfoot region 110 is adjacent to and adjacent to the forefoot region 108, and generally corresponds to the portion of the footwear 100 that surrounds the arch and bridge of the foot. The heel region 112 is adjacent to and adjacent to the midfoot region 110, and generally corresponds to the portion of the footwear 100 that surrounds the rear of the foot, including the heel or calcaneus, the ankle, and / or the Achilles tendon.

[0031] The uppers of many conventional shoes are formed from multiple elements (e.g., fabric, polymer foam, polymer sheet, leather, and synthetic leather) that are joined together by gluing or sewing at seams. In some embodiments, the upper 102 of the footwear article 100 is formed from a knitted structure or knitted component. In various embodiments, the knitted component can comprise various types of yarn that can provide different properties to the upper. For example, one area of ​​the upper 102 can be formed from a first type of yarn that imparts a first set of properties, and another area of ​​the upper 102 can be formed from a second type of yarn that imparts a second set of properties. Using this construction, the properties of the upper 102 can be varied throughout the upper 102 by selecting specific yarns for different areas of the upper 102.

[0032] Regarding one or more materials constituting the upper 102, the specific properties imparted by a particular type of yarn to the knitted component area depend, at least in part, on the materials of the various filaments and fibers forming the yarn. For example, cotton can provide a soft effect, biodegradability, or natural aesthetics to the knitted material. Elastic fibers and stretched polyesters can both provide the desired elasticity and resilience to the knitted component. Rayon materials can provide high luster and moisture absorption, wool can provide even stronger moisture absorption, nylon is a durable and abrasion-resistant material, and polyester is a durable material that provides hydrophobicity.

[0033] Other aspects of the knitted component can also be varied to influence its properties and provide desired attributes. For example, the yarn forming the knitted component may include monofilament yarn or multifilament yarn, or the yarn may include filaments formed from two or more different materials. Furthermore, the knitted component can be formed using specific knitting processes to impart specific properties to a particular area of ​​the knitted component. Therefore, various properties of a specific area of ​​the upper 102 can be imparted by selecting the material forming the yarn and other aspects of the yarn.

[0034] In some embodiments, after the knitted structure has a force applied laterally to it, the elasticity of the knitted structure can be measured based on a comparison of the width or length of the knitted structure in a first, unstretched state with the width or length of the knitted structure in a second, stretched state. In further embodiments, the upper 102 may also include additional structural elements. For example, in some embodiments, a heel pad or overlay (not shown) may be provided on the heel area 112 to provide additional support to the user's heel. In some cases, other elements (e.g., plastic materials, logos, trademarks, etc.) may also be applied and fixed to the outer surface using adhesive or thermoforming processes. In some embodiments, properties associated with the upper 102 (e.g., stitch type, yarn type) or characteristics associated with different stitch types or yarn types (such as elasticity, aesthetic appearance, thickness, breathability, or abrasion resistance) may vary.

[0035] Refer again Figure 1 The sole structure 104 is connected or secured to the upper 102, and extends between the user's foot and the ground when the footwear 100 is worn by the user. The sole structure 104 may include one or more components, including an outsole, midsole, heel, upper, and / or insole. For example, in some embodiments, the sole structure may include an outsole providing structural integrity and traction for the user, a midsole providing a cushioning system, and an insole providing arch support for the user. Furthermore, the insole may be a sprue, forefoot plate, last, or a combination thereof, and the insole may be positioned between the upper 102 and the sole structure 104, or the insole may be part of the upper 102.

[0036] Furthermore, the insole may be positioned within the internal cavity 106 of the upper 102, allowing it to directly contact the user's foot when the footwear 100 is worn. Additionally, the upper 102 may include a lining (not shown) that can enhance comfort, for example, by reducing friction between the user's foot and the upper 102, sole structure 104, insole, etc., and / or by providing moisture-wicking properties. The lining may be padded across the entire internal cavity 106 or only a portion of it. In some embodiments, a trim (not shown) may surround an opening in the internal cavity 106 to secure the lining to the upper 102 and / or provide an aesthetic element to the footwear 100.

[0037] refer to Figure 2 and Figure 3 The footwear article 100 further defines an outer side 116 and an inner side 118. When a user wears the shoe, the outer side 116 corresponds to the outward-facing portion of the footwear article 100, while the inner side 118 corresponds to the inward-facing portion of the footwear article 100. Thus, the footwear article 100 has opposing outer sides 116 and inner sides 118. The inner side 118 and the outer side 116 are adjacent to each other along a longitudinal center plane or central axis 120 of the footwear article 100, which is perpendicular to... Figure 1 The longitudinal axis L is coplanar. As will be further discussed herein, the longitudinal center plane or central axis 120 can define a central, intermediate axis between the inner side 118 and the outer side 116 of the footwear article 100. In other words, the longitudinal center plane or central axis 120 can extend between the rear proximal end 122 and the front distal end 124 of the footwear article 100, and can continuously define the middle of the insole 126, the sole structure 104 and / or the upper 102 of the footwear article 100, that is, the longitudinal center plane or central axis 120 is a straight axis extending through the rear proximal end 122 of the heel region 112 to the front distal end 124 of the forefoot region 108.

[0038] Unless otherwise stated, see reference. Figure 2 and Figure 3The footwear article 100 may be defined by a forefoot region 108, a midfoot region 110, and a heel region 112. The forefoot region 108 may generally correspond to the portion of the footwear article 100 surrounding the foot 128, which includes toes or phalanges 130, a ball of the foot 132, and one or more joints 134 connecting the metatarsals 136 of the foot 128 to the toes or phalanges 130. The midfoot region 110 is adjacent to and adjacent to the forefoot region 108. The midfoot region 110 generally corresponds to the portion of the footwear article 100 surrounding the arch and bridge of the foot 128. The heel region 112 is adjacent to and adjacent to the midfoot region 110. The heel region 112 generally corresponds to the portion of the footwear article 100 surrounding the rear of the foot 128, which includes the heel or calcaneus 138, the ankle (not shown), and / or the Achilles tendon (not shown).

[0039] Still referencing Figure 2 and Figure 3 The forefoot region 108, midfoot region 110, heel region 112, medial side 118, and lateral side 116 are intended to define the boundaries or areas of the footwear article 100. For this purpose, the various regions of the footwear article 100 are generally divided into the forefoot region 108, midfoot region 110, heel region 112, medial side 118, and lateral side 116. Certain aspects of this disclosure may relate to portions or elements that extend together with one or more of the forefoot region 108, midfoot region 110, heel region 112, medial side 118, and / or lateral side 116. Furthermore, the upper 102 and sole structure 104 have characteristic portions within the forefoot region 108, midfoot region 110, and heel region 112, and / or along the medial side 118 and / or lateral side 116. Therefore, the upper 102 and sole structure 104, and / or individual portions of the upper 102 and sole structure 104, may be included within the forefoot region 108, midfoot region 110, heel region 112, and / or along the medial side 118 and / or lateral side 116.

[0040] Still referencing Figure 2 and Figure 3The diagram details the forefoot region 108, midfoot region 110, heel region 112, medial side 118, and lateral side 116. The forefoot region 108 extends from the toe tip 140 of the footwear article 100 to its widest portion 142. The widest portion 142 is defined or measured along a first line 144 perpendicular to a central axis 120, which extends from the distal portion of the toe tip 140 to the distal portion of the heel tip 146 opposite to the toe tip 140. The midfoot region 110 extends from the widest portion 142 of the footwear article 100 to its narrowest portion 148. The narrowest portion 148 of the footwear article 100 is defined as the narrowest part of the footwear article 100, which is measured across a second line 150 perpendicular to the central axis 120. The heel region 112 extends from the narrowest portion 148 of the footwear article 100 to the heel tip 146.

[0041] It should be understood that, given the foregoing description, many modifications will be apparent to those skilled in the art, and their individual components can be incorporated into many footwear articles. Therefore, aspects of footwear article 100 and its components can be described with reference to the general areas or portions of footwear article 100, while understanding that the boundaries of the forefoot region 108, midfoot region 110, heel region 112, medial side 118, and / or lateral side 116 as described herein can vary between footwear articles. However, aspects of footwear article 100 and its individual components can also be described with reference to the exact areas or portions of footwear article 100, and the scope of the appended claims can include limitations associated with these boundaries of the forefoot region 108, midfoot region 110, heel region 112, medial side 118, and / or lateral side 116 discussed herein.

[0042] Still referencing Figure 2 and Figure 3 The medial side 118 begins at the distal end of the toe tip 140 and curves outward along the medial side of the footwear 100 along the forefoot region 108 toward the midfoot region 110. The medial side 118 reaches the first line 144, at which point it curves inward toward the longitudinal central axis 120. The medial side 118 extends from the first line 144 (i.e., the widest portion 142) toward the second line 150 (i.e., the narrowest portion 148), at which point (i.e., when intersecting with the first line 144) the medial side 118 enters the midfoot region 110. Once reaching the second line 150, the medial side 118 curves outward away from the longitudinal central axis 120, at which point (i.e., when intersecting with the second line 150) the medial side 118 extends to the heel region 112. The medial side 118 then curves outward, then inward toward the heel tip 146, and terminates at the point where the medial side 118 intersects with the longitudinal central axis 120.

[0043] The lateral side 116 also begins at the distal end of the toe tip 140 and curves outward along the lateral side of the footwear 100 from the forefoot region 108 toward the midfoot region 110. The lateral side 116 reaches the first line 144, at which point it curves inward toward the longitudinal central axis 120. The lateral side 116 extends from the first line 144 (i.e., the widest portion 142) toward the second line 150 (i.e., the narrowest portion 148), at which point (i.e., when intersecting with the first line 144) the lateral side 116 enters the midfoot region 110. Once reaching the second line 150, the lateral side 116 curves outward away from the longitudinal central axis 120, at which point (i.e., when intersecting with the second line 150) the lateral side 116 extends to the heel region 112. The lateral side 116 then curves outward, then inward toward the heel tip 146, and terminates at the point where the lateral side 116 intersects with the longitudinal central axis 120.

[0044] Still referencing Figure 2 and Figure 3 The upper 102 extends along the outer side 116 and the inner side 118, and spans the forefoot region 108, the midfoot region 110, and the heel region 112 to accommodate and surround the user's foot. When fully assembled, the upper 102 also includes an inner surface 162 and an outer surface 164. The inner surface 162 faces inward and generally defines an internal cavity 106, and the outer surface 164 faces outward and generally defines the outer periphery or boundary of the upper 102. The upper 102 also includes an opening 166 located at least partially in the heel region 112 of the footwear article 100, providing an entrance to the internal cavity 106, and through which the foot can put on and take off the shoe. In some embodiments, the upper 102 may also include an instep region 168 extending from the opening 166 in the heel region 112 through a corresponding area on the instep adjacent to the forefoot region 108. The instep area 168 may include an area similar to the area where the tongue 170 of this embodiment is disposed. In some embodiments, the upper 102 does not include the tongue 170, that is, the upper 102 is tongueless.

[0045] In the illustrated embodiment, the sole structure 104 includes a midsole 172 and an outsole 174. The outsole 174 may define a bottom end or bottom surface 176 of the sole structure 104, which spans the heel region 112, the midfoot region 110, and the forefoot region 108. Furthermore, the outsole 174 may be a ground contact portion or a ground contact surface including the sole structure 104, and is opposite to the insole of the sole structure 104. Figure 1As shown, the bottom surface 176 of the outsole 174 may include a sole pattern 178, which may include various shapes and constructions. The outsole 174 may be formed of one or more materials to impart durability, abrasion resistance, wear resistance, or adhesive friction to the sole structure 104. In some embodiments, the outsole 174 may be formed of any kind of elastomeric material, such as rubber, including thermosetting elastomers or thermoplastic elastomers, or thermoplastic materials, such as thermoplastic polyurethane (TPU). In some embodiments, the outsole 174 may be defined with a Shore A hardness of up to 95. Furthermore, the outsole 174 may be manufactured by processes such as injection molding, vulcanization, layer-by-layer printing (i.e., additive manufacturing systems or methods).

[0046] Still referencing Figure 1 The midsole 172 may be composed solely of a thermoplastic material, such as polyurethane (PU) and / or ethylene-vinyl acetate (EVA), copolymers thereof, or similar materials. In other embodiments, the midsole 172 may be an EVA-solid sponge (“ESS”) material, EVA foam (e.g., PUMA® ProFoam Lite), or similar materials. TM The midsole 172 can be a single polymeric material or a mixture of multiple materials, such as EVA copolymers, thermoplastic polyurethanes, polyether block copolymers, organic sheets, thermoplastic materials (e.g., thermoplastic polyurethanes, thermoplastic elastomers, thermoplastic polyolefins, etc.), or supercritical foams.

[0047] In embodiments where the midsole 172 is formed by a supercritical foaming process, the supercritical foam may comprise microporous or particulate foams, such as TPU, EVA, PEBAX®, or mixtures thereof. This supercritical foam is generated by mixing a supercritical fluid (e.g., CO2, N2, or mixtures thereof) with a preferably molten material (e.g., TPU, EVA, polyolefin elastomers, or mixtures thereof) within an autoclave, injection molding equipment, or any container capable of sufficient heating / pressurization. In an exemplary process, a solution of supercritical fluid and molten material is pumped into a pressurized container, and then the pressure within the container is released, causing the molecules of the supercritical fluid to rapidly convert into gas to form vesicles within the material and to expand the material into a foam. In other embodiments, the midsole 172 may be formed using alternative methods known in the art, including the use of an expansion press, injection molding machine, particulate expansion process, cold foaming process, compression molding technology, die cutting, or any combination thereof. For example, the midsole 172 may be formed using a process involving an initial foaming step, in which a supercritical gas is used to foam the material, which is then compression molded or die-cut into a specific shape.

[0048] Figure 4 A schematic diagram of a footwear article 200 with a fastening system 204 is depicted. The fastening system 204 includes a fastening mechanism 208 and a shoelace 212 operably coupled to the upper 102 and the fastening mechanism 208 to tighten and / or loosen the footwear article 200.

Furthermore, the fastening system 204 includes a cable 214, one end of which has a handle or loop 216 configured to be pulled by a user to actuate the fastening system 204 to perform one or more functions, such as tightening, unlocking, or retracting. For this purpose, the cable 214 is configured to be pulled away from the fastening mechanism 208 in one or more directions to activate at least one function of the fastening system 204, and the cable 214 is configured to retract into the fastening mechanism 208 to prevent tangling, as will be described herein.

[0049] In some embodiments, the fastening system 204 is embedded in the upper 102. In some embodiments, the fastening system 204 can be detached from the upper 102 and transferred to different footwear articles 200. In some embodiments, the fastening mechanism 208 is mounted on the upper 102, located on the inner side 118 of the footwear article 200, within the midfoot region 110. In some aspects, the fastening mechanism 208 is located within the heel region 112 of the upper 102.

[0050] Figure 5 A fastening mechanism 208 is depicted, which is configured to attach to the shoe 200 (see...). Figure 4 The fastening mechanism 208 includes a top cover 220 and a base 224, which are connected together by a screw 228 and a nut 230 (see...). Figure 6 The cover 220 is defined by a circular front surface 232, which includes an outer wall 234 that is perpendicular to and remote from the rear surface 236 of the cover (e.g., Figure 7 As shown, the outer wall 234 extends to form a cap-like structure with a circular profile. The top cover 220 can have various designs and colors. The front surface 232 includes a central hole 238 that is axially aligned with a central axis CA extending through the center of the fastening mechanism 208. The front surface 232 includes an intermediate hole 240 disposed between the central hole 238 and the peripheral edge 242 of the front surface 232. The central hole 238 receives a screw 228 that connects the top cover 220 to the chassis 224 of the fastening mechanism 208. The outermost hole 244 is disposed adjacent to the peripheral edge 242 of the front surface 232. In the illustrated embodiment, the intermediate hole 240 receives a dynamic bolt 246, which is at least partially located in or through the hole. The outermost hole 244 receives a first end 248 of a cable 214, which is at least partially located in or through the hole. The outer wall 234 of the cover 220 includes a plurality of teeth 250 radially disposed between the peripheral edge 242 of the front surface 232 and the outer wall edge 252.

In the illustrated embodiment, the chassis 224 includes an internal volume 276 defined by an outer chassis wall 262. The internal volume 276 of the chassis 224 includes an intermediate wall 278, a central rod 280, and a central bore 282, which are concentrically arranged relative to each other about a central axis CA. The intermediate wall 278 is disposed between the central rod 280 and the outer chassis wall 262, and the central bore 282 extends between the rear surface 274 of the flange 258 and the edge 284 of the central rod.

[0053] A center rod 280 is disposed within an intermediate wall 278, which defines an inner cavity 286. The center rod 280 within the inner cavity 286 receives a winding reel 288. The intermediate wall 278 includes a pocket 290 disposed outside the intermediate wall 278. An intermediate channel 292 is defined between an outer chassis wall 262 and the intermediate wall 278, and further defines an intermediate surface 294.

[0055] The fastening system 204 includes a fixed latch 320, a floating latch 322, and a pinion 324 integrally formed with the winding reel 288. The fixed latch 320 includes a first arm 328, a second arm 330, a main hole 332, and a secondary hole 334. The main hole 332 of the fixed latch 320 is connected to the pocket 290 of the chassis 224 via a static bolt 338 inserted therein. The static bolt 338 defines a longitudinal axis LAS configured parallel to but offset from the central axis CA. A pin 340 is inserted into the secondary hole 334 of the fixed latch 320 and connected to a first latch end 344 of the spring element 296. The floating latch 322 includes a main arm 348, a main hole 350, a recessed region 352, and a slot 354 disposed near the recessed region 352. The slot 354 is connected to the spring element 296 via a second latch end 358. The main hole 350 of the floating latch 322 is connected to the intermediate hole 240 of the upper cover 220 via a dynamic bolt 246. Furthermore, the main hole 350 is axially aligned with the longitudinal axis LAD defined by the dynamic bolt 246. The longitudinal axis LAD of the dynamic bolt 246 is configured to be coaxial with the longitudinal axis LAS of the static bolt 338, such that both are parallel to and offset from the central axis CA. During radial movement (e.g., rotation), the floating latch 322 moves above the fixed latch 320, and the thickness of the pinion 324 is approximately equal to the sum of the thicknesses of the floating latch 322 and the fixed latch 320.

[0056] The pinion 324 is integrally formed with the winding reel 288, which is received by the cavity 286 of the chassis 224. In some embodiments, the pinion 324 and the winding reel 288 may be joined by adhesive or by welding to form a pinion-winding reel assembly 360. The pinion 324 of the pinion-winding reel assembly 360 includes a plurality of teeth 362 arranged circumferentially around the pinion 324 and radially spaced from each other. Each of the plurality of teeth 362 of the pinion 324 may be configured as a straight tooth shape or a helical shape. In some embodiments, the respective shapes of the first arm 328, the second arm 330 of the retaining latch 320, and / or the main arm 348 of the floating latch 322 are similar to or analogous to the shape of the teeth 362 of the pinion 324 to facilitate engagement during certain operating functions. The winding reel 288 also includes a cylinder 364 extending along a central axis CA between an outer flange 366 and an inner flange 368. The outer flange 366 defines the front outer flange surface 370 and the rear outer flange surface 372, and the inner flange 368 defines the front inner flange surface 374 and the rear inner flange surface 376 (e.g., Figure 7(As shown). The pinion-winding wheel assembly 360 includes a central bore 378 arranged coaxially with the central axis CA. The central bore 378 is axially aligned with the central bore 282 of the chassis 224 and the central bore 238 of the top cover 220, and is connected using screws 228 and nuts 230.

[0057] refer to Figure 7 A cross-sectional view of the fastening mechanism 208 is shown. The flange 258 of the chassis 224 can be convexly bent relative to the top cover 220, such that the flange 258 is configured to adapt to the curvature of the shoe 200 when mounted on the shoe 200 and lie flush with the curvature of the shoe 200 (see Figure 200). Figure 4 In some embodiments, the flange 258 of the chassis 224 may be concave relative to the cover 220. Optionally, the flange 258 may be flat or planar. The screw 228 includes a screw head 384, a shank or shaft 386, and rolled threads 388. Figure 7 As shown, when connected, screw 228, top cover 220, chassis 224, pinion-winding wheel assembly 360, and nut 230 are coaxial with the central axis CA. Screw head 384 is arranged to abut against a lateral stop 390 on the front surface 232 of top cover 220, while nut 230 engages with the rolled thread 388 of screw 228 within a rearmost cavity 392 located on the rear surface 274 of chassis 224. Pinion-winding wheel assembly 360 is connected between chassis 224 and top cover 220 along the axis 386 of screw 228. Top cover 220 and pinion-winding wheel assembly 360 are configured to rotate about the central axis CA. The rear inner flange surface 376 of pinion-winding wheel assembly 360 is configured to at least partially surround and rotate along the central rod 280 of chassis 224. The foremost surface 394 of the pinion 324 is disposed opposite to the rear inner flange surface 376 of the winding wheel 288. During assembly, the foremost surface 394 is disposed adjacent to the rear cover surface 236 of the upper cover 220.

[0058] Still referencing Figure 7 The dynamic bolt 246 includes a bolt head 402, an intermediate shaft 404, and a distal shaft 406. The intermediate shaft 404 of the dynamic bolt 246 is connected to the main hole 350 of the floating latch 322 (e.g., Figure 6(As shown) Received. The distal shaft 406 of the dynamic bolt 246 is inserted into the intermediate hole 240 of the cover 220. In some embodiments, the bolt head 402 serves as a radial stop 408. For example, the cover 220 is configured to rotate about a central axis CA when the cable 214 is pulled. Once the cover 220 rotates about the central axis CA, the dynamic bolt 246, including the floating latch 322, rotates about the central axis CA and may encounter the fixed latch 320. The bolt head 402 is configured to abut against the fixed latch 320 to prevent the cover 220 from rotating beyond a predetermined range of motion. The floating latch 322 is connected to the second latch end 358 of the spring element 296.

[0059] A guide groove 256 is disposed between the upper cover 220 and the chassis 224. The upper cover 220 can rotate clockwise and / or counterclockwise based on the pulling or retraction of the cable 214. The upper cover 220 partially receives the outer chassis wall 262 forming the guide groove 256. A chamber 412, in fluid communication with a first external opening 306 and a second external opening 308 of the outer chassis wall 262, is formed radially around the winding wheel 288 of the pinion-winding wheel assembly 360. The chamber 412 can receive the shoelaces (not shown) of the shoe 200.

[0060] refer to Figure 8 The fastening mechanism 208 includes an annular intermediate portion 416 and an annular outermost portion 418, which are coaxial and concentric. The outermost portion 418 includes a recessed surface 420, and the annular intermediate portion 416 includes a raised surface 421, which is concentrically located inside the annular outermost portion 418. The annular intermediate portion 416 and the annular outermost portion 418 are separated by an intermediate wall 278. The intermediate wall 278 may form integrally with it a pocket 290 for defining a receiving area for a static bolt 338. The recessed surface 420 at least partially surrounds the raised surface 421. The guide channel 310 of the container 260 may include inlets and / or outlets of different sizes. For example, the guide channel 310 may include an inlet 422 and an outlet 424. The inlet 422 is the location where the cable 214 is first received, and the outlet 424 is the location where the cable 214 exits the guide channel 310. In this disclosure, the inlet 422 of the guide channel 310 is larger than the outlet 424 of the guide channel 310. In some embodiments, the inlet 422 and outlet 424 of the guide channel 310 may differ in size and / or shape from those illustrated.

[0061] refer to Figure 9 and Figure 10 This shows the pinion-winding wheel assembly 360. See details. Figure 9The pinion-winding reel assembly 360 includes a pinion 324 and a central bore 378, the diameter of which is larger than that of the screw 228 to provide free rotation clockwise and counterclockwise about a central axis CA. The rear inner flange surface 376 of the winding reel 288 includes a cutout 428. The cutout 428 is located between a plurality of holes 430 extending through the cylinder 364 of the winding reel 288. See details. Figure 10 A plurality of holes 430 are perpendicularly spaced from the central axis CA and arranged with different offset distances relative to the central axis CA. In some embodiments, the center 432 of one of the holes 430 may be farther from the central axis CA than the center of another hole. For example, in this disclosure, the distance between the central axis CA and the upper hole group 434 is less than the distance between the central axis CA and the lower hole group 436. In some embodiments, the upper hole group 434 and the lower hole group 436 may be arranged in different ways, for example, providing an upper hole group 434 and a lower hole group 436 equidistant from the central axis CA.

[0062] Figure 11 The initial actuation position 450 of the fastening mechanism 208 is depicted. The center point CP1 of the dynamic bolt 246 defines the longitudinal axis LAD of the dynamic bolt, the center point CP2 of the static bolt 338 defines the longitudinal axis LAS of the static bolt, and the central axis CA intersects the center point CP3 of the screw 228. Figure 11 As shown, for reference, the X-axis and Y-axis define the first quadrant 452, the second quadrant 454, the third quadrant 456, and the fourth quadrant 458 in a counterclockwise direction. In the initial actuation position 450 of the illustrated embodiment, the center point CP2 of the static bolt 338 is arranged to be collinear with and intersect the X-axis, and is at least partially located within the second quadrant 454 and the third quadrant 456 along the X-axis. Furthermore, when in the initial actuation position 450, the center point CP1 of the dynamic bolt 246 is located within the second quadrant 454. The repose angle or initial angle 462 of the initial position may be defined relative to the central axis CA between the longitudinal axis LAD of the dynamic bolt and the longitudinal axis LAS of the static bolt (see...). Figure 6The portion of the X-axis that intersects with the center point CP2 and the longitudinal axis LAS of the static bolt defines a reference plane or reference axis 464 between the second quadrant 454 and the third quadrant 456. The initial angle 462 of the initial actuation position 450 refers to the angle measured relative to the central axis CA between the center point CP2 of the static bolt 338 and the center point CP1 of the dynamic bolt 246 in the initial actuation position 450. In other words, the initial angle 462 represents the angular position of the center point CP2 of the dynamic bolt 246 relative to the reference axis 464 in the initial actuation position 450. The initial angle 462 of the initial position can be between approximately 25 degrees and approximately 89 degrees, or between approximately 30 degrees and approximately 85 degrees, or between approximately 70 degrees and approximately 80 degrees. In some cases, the initial angle 462 is between approximately 80 degrees and approximately 89 degrees, or approximately 85 degrees.

[0063] Figure 12 The intermediate actuated position 480 of the fastening mechanism 208 is depicted. Cable 214 is configured to be pulled through container 260, thereby moving the top cover 220 of the fastening mechanism 208 clockwise about the central axis CA. A floating latch 322 engages with at least one tooth of a plurality of teeth 362 of pinion 324 to maintain tension on spring element 296. The floating latch 322 rotates clockwise together with dynamic latch 246, and the longitudinal axis LAD of the dynamic bolt moves along the first quadrant 452 and fourth quadrant 458 toward the third quadrant 456. The intermediate angle 482 refers to the angle measured relative to the central axis CA between the center point CP2 of the static bolt 338 and the center point CP1 of the dynamic bolt 246 in the intermediate actuated position 480. In other words, the intermediate angle 482 represents the angular position of the center point CP2 of the dynamic bolt 246 relative to reference axis 464 in the intermediate actuated position 480. The midpoint angle of 482 can be between approximately 90 degrees and approximately 269 degrees.

[0064] Figure 13The final actuated position 500 of the fastening mechanism 208 is depicted. Cable 214 is configured to be pulled through container 260, thereby moving the top cover 220 of the fastening mechanism 208 clockwise about the central axis CA. The longitudinal axis LAD of the dynamic bolt 246 is connected to a floating latch 322 disposed within the third quadrant 456 of the fastening mechanism 208. The final angle 502 of the final position refers to the angle measured relative to the central axis CA between the center point CP2 of the static bolt 338 and the center point CP1 of the dynamic bolt 246 in the final actuated position 500. In other words, the final angle 502 of the final position represents the angular position of the center point CP2 of the dynamic bolt 246 relative to the reference axis 464 in the final actuated position 500. The final angle 502 of the final position can be between approximately 270 degrees and approximately 355 degrees. In some cases, the final angle 502 can be approximately 270 degrees, or approximately 280 degrees, or approximately 290 degrees, or approximately 320 degrees. Therefore, the midpoint angle is 482 (see...) Figure 12 The final angle 502 is greater than the initial angle 462, and the final angle 502 is greater than the intermediate angle 482. In some cases, the final angle 502 is approximately 65% ​​to approximately 95% greater than the initial angle 462.

[0065] Figure 14 A method 600 for operating a fastening system 204 of footwear article 200 is described. Operation of the fastening system 204 of shoe 200 begins with a first step 610, which includes inserting a user's foot into an opening 166 of shoe 200. Once the user's foot is inserted into the opening 166, a second step 620 initiates actuation of a first mechanism to adjust the tightness of the shoe. The user pulls cable 214 to overcome the spring force of spring element 296 and disengages a floating latch 322 from a plurality of teeth 362 of pinion-winding wheel assembly 360. As described above, the floating latch 322 is configured to abut against the fixed latch 320 and disengage at a position at least about 270 degrees to a reference axis 464. In some embodiments, the shoelace 212 can be repeatedly pulled for incremental adjustment. It is conceivable that the magnitude of the incremental adjustment achieved by such repeated pulling actuation is proportional to the size of the cylinder 364 of pinion-winding wheel assembly 360. In some cases, the cylinder 364 of the pinion-winding wheel assembly 360 can be reduced, allowing for fine adjustment of the tightness, but requiring more repetitive actuations. In other cases, the cylinder 364 of the pinion-winding wheel assembly 360 can be increased, allowing for coarse adjustment of the tightness, but requiring fewer repetitive actuations. In the third step 630, the tightness of the shoe is evaluated. The tightness of the shoe 200 occurs due to the introduction of a spring load, which may cause the pinion-winding wheel assembly 360 to rotate counterclockwise, resulting in a greater length of the shoelace 212 wound around the cylinder 364 of the winding wheel 288.

[0066] Step 640 includes actuating a second mechanism, such as pulling a cable 214 connected to the top cover 220, to adjust the tightness of the shoe. In some embodiments, step 640 includes pulling the cable 214, which causes the top cover 220 to rotate clockwise about its central axis CA. A floating latch 322 connected to the top cover 220 engages with at least one tooth of a plurality of teeth 362 of the pinion-winding wheel assembly 360. The engagement between at least one tooth of the plurality of teeth 362 and the floating latch 322 allows the winding wheel 288 to progressively wind the length of the shoelace 212 onto the cylinder 364 to progressively adjust the tension of the shoelace 212, thereby tightening the shoe 200. The user proceeds to decision step 650 to determine whether the desired tightness has been achieved. If the desired tightness has not been achieved, the user can assess the tightness of the shoe 200 and adjust the tightness of the shoe 200 by returning to step 630. Once the shoelace 212 reaches the desired tension, the retaining buckle 320 engages with at least one of the teeth 362 of the pinion 324, holding the pinion-winding wheel assembly 360 in place. As the floating buckle 322 also engages with at least one of the teeth 362 of the pinion 324, the tension between the spring element 296 connected to the retaining buckle 320 and the floating buckle 322 increases. The partially closed position is achieved by the engagement of the retaining buckle 320 and the floating buckle 322 with at least one of the teeth 362 of the pinion 324, which increases the tension of the spring element 296.

[0067] The user proceeds to decision step 660, where they decide whether to remove the shoes 200. If the user decides to remove the shoes 200 (i.e., yes) at decision step 660, the fifth step 670 includes loosening the shoelaces 212 to remove the user's foot from the shoes 200 after use. The shoelaces 212 loosen as the cover 220 of the fastening mechanism 208 rotates counterclockwise. In other embodiments, the shoelaces 212 can be loosened by pulling the cable 214 attached to the cover 220. As the cover 220 rotates counterclockwise, the floating latch 322 attached to the cover 220 disengages from at least one of the teeth 362 of the pinion 324 by sliding away from it. Subsequently, simultaneously, the winding wheel 288 of the pinion-winding wheel assembly 360 partially releases the shoelaces 212 from the final actuated position 500. As described above, the bolt head 402 of the dynamic bolt 246 is connected to the floating latch 322 and the top cover 220. In the illustrated embodiment, when the bolt head 402 of the dynamic bolt 246 abuts against the fixed latch 320 between the first arm 328 and the second arm 330, the dynamic bolt 246 exerts a thrust on the first arm 328 and the second arm 330 of the fixed latch 320, thereby disengaging the fixed latch 320 from the plurality of teeth 362 of the pinion 324 and releasing the tension of the shoelace 212. The sixth step 680 includes removing the user's foot from the shoe 200. If the user decides not to remove the shoe 200 at the decision step 660 (i.e., no), the shoe 200 can be worn until it is necessary to repeat any of the steps 620-650 to adjust the tightness of the shoe 200.

[0068] It is also conceivable that the fastening mechanism 208 may be similar to those disclosed in U.S. Patent Nos. 5,325,613, 5,600,875, 5,606,778, 5,638,588, 5,651,198, and 5,669,116, all of which are collectively assigned to Puma SE and are incorporated herein by reference in their entirety.
