[0002] This application claims the benefit and priority of U.S. Provisional Application No. 63 / 343803, filed May 19, 2022, which is incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure generally relates to a footwear article including a closure system, and more specifically, to a closure system including a disc heel fastening mechanism. 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 and defines the cavity that fully or partially covers the foot. In most cases, the upper extends over the instep and toe areas of the foot, crossing its inner and outer sides. 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 can allow the user to adjust certain dimensions of the upper or sole, allowing the upper to accommodate a wide variety of foot shapes and sizes.

[0006] The upper of many shoes can include a variety of materials, which are used to form the upper and 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, footwear products with increased comfort and a better fit, as well as improved closure mechanisms, are desired. A common closure mechanism uses laces to fasten the upper and tongue to the user's foot. While laces do provide a closure, they can break or come undone. Furthermore, over time, laces loosen and become less aesthetically pleasing. Therefore, there is a need for footwear products that can selectively provide a close fit of the upper and tongue to the user's foot, and selectively provide a looser fit to the user's foot when not using laces. 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 some aspects, footwear includes an upper, multiple eyelets, a disc, and laces. The upper is attached to a sole structure including a midsole extending into the heel region of the footwear.

[0037] 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 types, 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 footwear articles considered non-athletic, including dress shoes, sandals, casual shoes, slippers, and high heels. In addition to footwear, 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.

[0038] 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.

[0039] 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 methods, 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 various materials, such as first yarns, second yarns, and / or third yarns, which may have different properties or different visual characteristics.

[0040] Figures 1-3 An exemplary embodiment of footwear article 100 is shown, including upper 102 (see Figure 1 and Figure 2 The upper 102 is attached to the sole structure 104 and together they define the internal cavity 106 (see...). Figure 2 The foot can be inserted into the internal cavity 106. For reference, the footwear article 100 defines a forefoot region 108, a midfoot region 110, and a heel region 112. The forefoot region 108 generally corresponds to the portion of the footwear article 100 surrounding 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 abuts the forefoot region 108, and generally corresponds to the portion of the footwear article 100 surrounding the arch and bridge of the foot. The heel region 112 is adjacent to and abuts the midfoot region 110, and generally corresponds to the portion of the footwear article 100 surrounding the rear of the foot, including the heel or calcaneus, the ankle, and / or the Achilles tendon.

[0041] Many conventional footwear uppers are formed from multiple elements (e.g., fabric, polymer foam, polymer sheet, leather, and synthetic leather) that are joined together by bonding 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.

[0042] refer to Figure 1 and Figure 2 Regarding the materials (one or more) including the upper 102, specific types of yarn will impart specific properties to the knitted component areas, depending 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 each provide the desired elasticity and resilience to the knitted component. Rayon can provide a material with high luster and moisture absorption, wool can provide a material with enhanced moisture absorption, nylon can be a durable material with abrasion resistance, and polyester can provide a durable material with hydrophobic properties.

[0043] 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 each formed from two or more different materials. Furthermore, the knitted component can be formed using specific knitting processes to impart specific properties to certain areas of the knitted component. Therefore, the materials forming the yarn and other aspects of the yarn can be selected to impart multiple properties to specific areas of the upper 102.

[0044] Still referencing Figure 1 and Figure 2 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, the properties associated with the upper 102 may vary, such as stitch type, yarn type, or characteristics associated with different stitch types or yarn types, such as elasticity, aesthetic appearance, thickness, breathability, or abrasion resistance.

[0045] 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 strobel board, forefoot board, lasting board, or a combination thereof, and the insole may be positioned between the upper 102 and the sole structure 104, or it may be part of the upper 102.

[0046] Still referencing Figure 1 and Figure 2 In addition, the insole may be positioned within the internal cavity of the upper, allowing it to directly contact the user's foot when the footwear is worn. Furthermore, the upper may include a lining (not shown) that can enhance comfort, for example, by reducing friction between the user's foot and the upper, sole, insole, etc., and / or by providing moisture-wicking properties. The lining may be padded across the entire internal cavity or only a portion of it. In some embodiments, a trim (not shown) may surround an opening in the internal cavity to secure the lining to the upper and / or to the footwear, providing an aesthetic element.

[0047] refer to Figure 2 and Figure 3 The footwear article 100 further defines an outer side 114 and an inner side 116. When a user wears the shoe, the outer side 114 corresponds to the outward-facing portion of the footwear article 100, while the inner side 116 corresponds to the inward-facing portion of the footwear article 100. Thus, the footwear article 100 has opposing outer sides 114 and inner sides 116. The inner side 116 and the outer side 114 are adjacent to each other along a longitudinal central plane or central axis 118 of the footwear article 100, which is perpendicular to... Figure 1 The longitudinal axes L are coplanar. As will be discussed further herein, the central axis 118 can define a central, intermediate axis between the inner side 116 and the outer side 114 of the footwear article 100. In other words, the central axis 118 can extend between the rear proximal end 120 and the front distal end 122 of the footwear article 100, and can continuously define the middle of the insole 124, the sole structure 104 and / or the upper 102 of the footwear article 100, that is, the central axis 118 is a straight axis extending through the rear proximal end 120 of the heel region 112 to the front distal end 122 of the forefoot region 108.

[0048] refer to Figure 3Unless otherwise stated, footwear 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 footwear 100 surrounding the foot 126, which includes a set of toes or phalanges 128, a foot 130, and a set of joints 132 connecting a set of metatarsals 134 of the foot 126 to the set of toes or phalanges 128. The midfoot region 110 is adjacent to and adjacent to the forefoot region 108. The midfoot region 110 generally corresponds to the portion of footwear 100 surrounding the arch 136 of the foot 126 and the bridge 138 of the foot 126. 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 100 that surrounds the rear of the foot 126, which includes the heel or calcaneus 140, the ankle (not shown), and / or the Achilles tendon (not shown).

[0049] refer to Figure 1 and Figure 2 The forefoot region 108, midfoot region 110, heel region 112, medial side 116, and lateral side 114 are intended to define the boundaries or areas of the footwear article 100. For this purpose, the forefoot region 108, midfoot region 110, heel region 112, medial side 116, and lateral side 114 generally characterize the intervals of the footwear article 100. 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 116, and / or lateral side 114. Furthermore, both the upper 102 and the sole structure 104 are characterized by having portions within the forefoot region 108, midfoot region 110, and heel region 112, and / or along the medial side 116 and / or lateral side 114. Therefore, the upper 102 and sole structure 104, and / or individual portions of the upper 102 and sole structure 104 may include portions disposed within the forefoot region 108, midfoot region 110, heel region 112 and / or along the medial side 116 and / or lateral side 114.

[0050] refer to Figure 2 and Figure 3The forefoot region 108, midfoot region 110, heel region 112, medial side 116, and lateral side 114 are shown in detail. The forefoot region 108 extends from the toe tip 142 of the footwear article 100 to its widest portion 144. The widest portion 144 is defined or measured along a first line 146 perpendicular to a central axis 118, which extends from the distal portion of the toe tip 142 to the distal portion of the heel tip 148 opposite to the toe tip 142. The midfoot region 110 extends from the widest portion 144 of the footwear article 100 to its narrowest portion 150. The narrowest portion 150 of the footwear article 100 is defined as the narrowest part of the footwear article 100, which is measured across a second line 152 perpendicular to the central axis 118. The heel region 112 extends from the narrowest portion 150 of the footwear article 100 to the heel tip 148.

[0051] It should be understood that, given the foregoing description, many modifications will be apparent to those skilled in the art, and 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 116, and / or lateral side 114 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 specific 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 116, and / or lateral side 114 discussed herein.

[0052] Still referencing Figure 2 and Figure 3 The medial side 116 begins at the distal end of the toe tip 142 and curves outward along the medial side of the footwear 100 along the forefoot region 108 toward the midfoot region 110. The medial side 116 reaches the first line 146, at which point it curves inward toward the central axis 118. The medial side 116 extends from the first line 146 (i.e., the widest portion 144) toward the second line 152 (i.e., the narrowest portion 150), at which point (i.e., when intersecting with the first line 146) the medial side 116 enters the midfoot region 110. Once reaching the second line 152, the medial side 116 curves outward away from the central axis 118, at which point (i.e., when intersecting with the second line 152) the medial side 116 extends into the heel region 112. The medial side 116 then curves outward, then inward toward the heel tip 148, and terminates at the point where the medial side 116 intersects with the central axis 118.

[0053] The outer side 114 also begins at the distal end of the toe tip 142 and curves outward along the outer side of the footwear 100 along the forefoot region 108 toward the midfoot region 110. The outer side 114 reaches the first line 146, at which point it curves inward toward the central axis 118. The outer side 114 extends from the first line 146 (i.e., the widest portion 144) toward the second line 152 (i.e., the narrowest portion 150), at which point (i.e., when intersecting with the first line 146) the outer side 114 enters the midfoot region 110. Once reaching the second line 152, the outer side 114 curves outward away from the central axis 118, at which point (i.e., when intersecting with the second line 152) the outer side 114 extends into the heel region 112. The outer side 114 then curves outward, then inward toward the heel tip 148, and terminates at the point where the outer side 114 intersects with the central axis 118.

[0054] refer to Figure 2 The upper 102 extends along the outer side 114 and the inner side 116, 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 154 and an outer surface 156. The inner surface 154 faces inward and generally defines an internal cavity 106, while the outer surface 156 faces outward and generally defines an outer periphery or boundary of the upper 102. The upper 102 also includes an opening 158 located at least partially in the heel region 112 of the footwear article 100, providing an entrance to the internal cavity 106 through which the foot can be inserted and removed. In some embodiments, the upper 102 may also include an instep region 160 extending from the opening 158 in the heel region 112 in a region corresponding to the instep to a region adjacent to the forefoot region 108. The instep area 160 may include an area similar to the area where the tongue 162 of this embodiment is disposed. In some embodiments, the upper 102 does not include the tongue 162, that is, the upper 102 is tongueless.

[0055] refer to Figure 1 The sole structure 104 includes a midsole 164 and an outsole 166. The outsole 166 may define a bottom end or bottom surface 168 of the sole structure 104, which spans the heel region 112, the midfoot region 110, and the forefoot region 108. Furthermore, the outsole 166 may be a ground-contact portion or a ground-contact surface including the sole structure 104, and may be opposite the insole of the sole structure 104. Figure 1As shown, the bottom surface 168 of the outsole 166 may include a tread pattern 170, which may include various shapes and constructions. The outsole 166 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 166 may be formed of any type 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 166 may define a Shore A hardness of up to 95. Furthermore, the outsole 166 may be manufactured using processes involving injection molding, vulcanization, layer-by-layer printing (i.e., additive manufacturing systems or methods).

[0056] The midsole 164 may be solely composed of a thermoplastic material, such as polyurethane (PU) and / or ethylene-vinyl acetate (EVA), copolymers thereof, or similar materials. In other embodiments, the midsole 164 may be an EVA-solid sponge (“ESS”) material, EVA foam (e.g., ProFoam Lite TM The midsole 164 can be a single polymeric material or a mixture of multiple materials, such as EVA copolymers, thermoplastic polyurethanes, polyethers, olefin block copolymers, organic sheets, thermoplastic materials (e.g., thermoplastic polyurethanes, thermoplastic elastomers, thermoplastic polyolefins, etc.) or supercritical foams. In some embodiments, the midsole 164 is manufactured by processes involving injection molding, vulcanization, layer-by-layer printing (i.e., additive manufacturing systems or methods).

[0057] refer to Figure 1 In the embodiment where the midsole 164 is formed by a supercritical foaming process, the supercritical foam may include microporous foam or particulate foam, such as TPU, EVA, The supercritical foam, or a mixture thereof, is manufactured using a process performed in a fully heated / pressurized container, such as an autoclave, injection molding equipment, or any container capable of handling the mixing of a supercritical fluid (e.g., CO2, N2, or mixtures thereof) with a preferably molten material (e.g., TPU, EVA, polyolefin elastomer, or mixtures thereof). 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 another embodiment, the midsole 164 may be formed using alternative methods known in the art, including the use of an expansion press, injection molding machine, particle expansion process, cold foaming process, compression molding technique, die cutting, or any combination thereof. For example, the midsole 164 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.

[0058] refer to Figure 4 Another embodiment of the footwear article 200 with fastener system 204 is configured as a right shoe 208 and includes an upper 212 having a tongue 216 and a plurality of eyelets 220 adjacent to the tongue 216. The midsole 224 has a first body or midsole body 228 having a first hole or rear hole 232 on a first outer 236 of the midsole body 228 located in a heel region 112, the heel region 112 defining a first cavity or main cavity 240 defined by the rear hole 232. A right disc 244 is configured to partially fit within the main cavity 240 and protrude beyond the main cavity 240. The right disc 244 has a second body or disc body 248 having a first surface or top surface 252 (see...). Figure 8 ), the second surface or bottom surface 256 opposite to the top surface 252 (see Figure 12The top surface 252 of the right disc 244 is connected to the third surface or circumferential surface 260 of the bottom surface 256 along the second outer surface 264 of the right disc 244. A plurality of disc teeth 272 of the actuator mechanism 268 protrude from the circumferential surface 260 and are rigidly connected to the disc body 248. In other words, a plurality of disc teeth 272 of the right disc 244 are circumferentially arranged thereon. The plurality of disc teeth 272 are arranged to be exposed on the exterior of the main cavity 240 of the sole structure 104 of the footwear 200. The top surface 252 of the right disc 244 includes a lace fastener 276 that secures or retains a lace or lace 280. The lace 280 is secured to the lace fastener 276 via a first end 284, extends through the upper 212, then through a plurality of eyelets 220, and then extends to and is secured to the lace fastener 276. When the shoelace 280 is under tension, a downward force or compressive force 288 presses on the footwear 200, for example, on the midfoot area 110 of the right shoe 208.

[0059] refer to Figure 5 Footwear article 200 is configured as a right shoe 208 having a right disc 244 and a left shoe 292 having a left disc 296. The left shoe 292 and the left disc 296 have the same but mirror-image elements as those introduced as part of the right shoe 208 and the right disc 244, including a plurality of disc teeth 272. The plurality of disc teeth 272 of the right disc 244 are configured to engage or engage with the plurality of disc teeth 272 of the left disc 296. For example, when the plurality of disc teeth 272 of the right disc 244 engages with the plurality of disc teeth 272 of the left disc 296, an exemplary right tooth 300 of the plurality of disc teeth 272 of the right disc 244 contacts an exemplary left tooth 304 of the plurality of disc teeth 272 of the left disc 296. Upon contact, a lateral force 308 from one of the left teeth 304 or the right teeth 300 can be transmitted to the other of the two teeth. The transmission of the lateral force 308 to the left tooth 304 tends to generate a rotational force 312 in the left disc 296, while the transmission of the lateral force 308 to the right tooth 300 tends to generate a rotational force 312 in the right disc 244. Therefore, when the left disc 296 engages with the right disc 244, both the left and right discs can rotate. The rotational initiation of the right disc 244 or the left disc 296 can be increased or decreased by the contact between the two discs 244, 296. Furthermore, for more details regarding how the rotation of the two discs 244, 296 can also be driven by energy stored in the shoelace 280, see the section below. Figure 8 and Figure 9 The discussion.

[0060] refer to Figure 6The right disc 244 of the right shoe 208 is shown to be capable of rotating in response to a rotational force 312. In the illustrated embodiment, a plurality of disc teeth 272 extend outward from the main cavity 240 around the heel end 148 of the footwear 200, and in particular, the plurality of disc teeth 272 are disposed within the heel region 112 along the inner side 116 and outer side 114 of the footwear 200. The right disc 244 can be rotated by applying forces from various sources, including by manual contact, the user's hand, the opposing shoe or disc, or by pressing the plurality of disc teeth 272 against an object such as a rock, a fence, or a car tire.

[0061] refer to Figure 7 The right shoe 208 is shown without laces 280. A midsole 224 is located between the outsole 166 and the upper 212. Multiple eyelets 220 are located adjacent to the tongue 216 on the outer side 114 and inner side 116, respectively. The midsole body 228 defines a second or side eyelet 316, which defines a first or side channel 320 on the outer side 114 of the right shoe 208. A release mechanism 324 of the release actuator 328 protrudes or extends from the side channel 320 of the sole structure 104. A right disc 244 protrudes beyond the main cavity 240, and at least a portion of the multiple disc teeth 272 are located on the outer side of the rear hole 232 and the main cavity 240, on the inner side 116, the outer side 114, and along the heel end 148. In some embodiments, the multiple disc teeth 272 protrude beyond the rear hole 232 only on the inner side 116 or the outer side 114. In the illustrated embodiment, the release mechanism 324 is disposed in the sole structure 104 and in front of the right disc 244. In some embodiments, the release mechanism 324 may be disposed behind the right disc 244, or coextensively with the foremost or rearmost point of the right disc 244. In some embodiments, the release mechanism 324 is disposed on the upper 102. In some embodiments, the release mechanism 324 is disposed on the inner side 116 or in the instep region 160. In some embodiments, the release mechanism 324 is disposed in the forefoot region 108 or the heel region 112.

[0062] Figure 8 An arrangement is shown in which shoelaces 280 extend outward from shoelace fastener 276 of the right disc 244 to a plurality of eyelets 220 and then return to shoelace fastener 276. Shoelaces 280 are configured without loops 332, see [reference needed]. Figure 9The shoelace 280 includes a third body or shoelace body 336 having a first end 284 and a second end 340 located at opposite ends of the shoelace body 336. The shoelace 280 is flexible and capable of transmitting tension or strain. In some embodiments, the shoelace is made of fabric, plastic-coated fabric, or flexible plastic weave. The shoelace fastener 276 of the right disc 244 has a first center 344 that intersects a first axis 348 extending perpendicularly from the top surface 252. The right disc 244 rotates about the first axis 348 in the heel region 112. In some embodiments, the first axis 348 is arranged orthogonally to the central axis 118 (see...). Figure 1 In some embodiments, the first axis 348 is aligned with the central axis 118 of the right shoe 208 (see...). Figure 3 In some embodiments, the first axis 348 does not intersect with the central axis 118 of the right shoe 208 (see...). Figure 3 The shoelace fastener 276 includes a first post or disc post 352 connected to a first fastener 356 and a second fastener 360. The first fastener 356 is configured to secure a first end 284 of the shoelace 280, and the second fastener 360 is configured to secure a second end 340 of the shoelace 280. The disc post 352 also includes a third hole or upper hole 364. The third hole or upper hole 364 intersects with a first axis 348 and defines a second cavity or upper cavity 368. The first end 284 and the second end 340 can be held or secured to the first fastener 356 or the second fastener 360 by welding, overmolding, interference fit, forming knots at the first end 284 and the second end 340 to secure them, by adhesive, or by winding the first end 284 and the second end 340 around the disc post 352 to secure the shoelace 280 to the shoelace fastener 276. The first edge or top edge 372 of the top surface 252 contacts the circumferential surface 260 and has a circular shape centered on the first axis 348. A plurality of disc teeth 272 protrude radially outward from the top edge 372, away from the first axis 348.

[0063] In some embodiments, the first end 284 is secured to the first retainer 356 of the shoelace retainer 276. In some embodiments, before the shoelace 280 passes through the left sleeve (or left sheath) 380, the shoelace 280 is wound around the circumference 376 of the shoelace retainer 276 (see...). Figure 9 The shoelace 280 extends through one of the multiple eyelets 220 on the inside 116 (see...). Figure 7 ), and then extends to one of the multiple eyelets 220 on the outer side 114 (see Figure 7The shoelace 280 extends back and forth until it connects the multiple eyelets 220 on the inner side 116 with the multiple eyelets 220 on the outer side 114. The shoelace 280 extends into the right sleeve (or right sheath) 384. The shoelace 280 extends into the shoelace fastener 276.

[0064] refer to Figure 9 In some embodiments, before securing the second end 340 to the shoelace retainer 276, the shoelace 280 is wound around the circumference 376 of the shoelace retainer 276 to form a loop 332. The second end 340 of the shoelace 280 is secured to the second retainer 360. Once arranged in this way, when the right disc 244 is subjected to a rotational force 312 (see... Figure 6 When rotation is caused, the shoelace 280 will wind or unwind around the circumference 376 of the shoelace retainer 276. Furthermore, the tension in the shoelace 280 is stored as potential energy 388. When the shoelace 280 is wound around the shoelace retainer 276, the shoelace 280 forms a loop 332 around the circumference 376 of the shoelace retainer 276, and as the tension in the shoelace 280 increases, the amount of potential energy 388 stored in the tension of the shoelace 280 increases. The tension of the shoelace 280 generates a downward force 288 in the midfoot region 110 (see...). Figure 4 As the size of coil 332 increases, the amount of potential energy 388 stored as tension in shoelace 280 increases. As the amount of potential energy 388 stored as tension in shoelace 280 increases, the magnitude of downward force 288 increases.

[0065] refer to Figure 8 and Figure 9 In some embodiments, the left sheath 380 and the right sheath 384 (see Figure 8 The shoelaces 276 are made of a relatively rigid and dense material compared to the material of the shoelaces 276. In some embodiments, the left sleeve 380 and the right sleeve 384 may be made of a flexible or rigid plastic material. In some embodiments, the two sleeves 380, 384 facilitate guiding the shoelaces 280 to the shoelace fastener 276. In some embodiments, the left sleeve 380 and the right sleeve 384 guide the shoelaces 280 through the upper 212, the outer side of the upper 212, or the inner side of the upper 212, and also through the midsole 224 to reach the rear eyelet 232 (see also...). Figure 4 ).

[0066] refer to Figure 10 The outer side 114 of the right shoe 208 shows a lace 280 extending through multiple eyelets 220 on the outer side 114 of the upper 212. Multiple disc teeth 272 of the right disc 244 extend outward from the rear hole 232 and main cavity 240 on the outer side 114 and heel end 148. The midsole body 228 defines a side hole 316, which defines a side channel 320. A release actuator 328 extends through the side channel 320.

[0067] refer to Figure 11 The disc post 352 of the shoelace fastener 276 of the right disc 244 intersects the first axis 348 and is connected to the first fastener 356 and the second fastener 360. In some embodiments, the right disc 244 is made of rigid plastic or metal. In some embodiments, the first fastener 356 is offset by 180 degrees from the second fastener 360 about the first axis 348. In some embodiments, the first fastener 356 and the second fastener 360 are configured as open loops or closed loops to retain or secure the first end 284 and the second end 340 of the shoelace 280 (see...). Figure 8 and Figure 9 The circumferential surface 260 includes a fourth surface (or radial surface) 392, a fifth surface (or left surface) 396, and a sixth surface (or right surface) 400. The radial surface 392 extends radially outward from the first axis 348 and is located along the circumferential surface 260 between each of the plurality of disk teeth 272. Each of the plurality of disk teeth 272 has a left surface 396 and a right surface 400, the left surface 396 facing an adjacent disk tooth among the plurality of disk teeth 272, and the right surface 400 facing away from the left surface 396. That is, the left surface 396 faces one side of the plurality of disk teeth 272, and the right surface 400 faces the other side of the plurality of disk teeth 272. The engagement or meshing of the right tooth 244 and the left tooth 304 (see...) Figure 5 It occurs at 396 on the left surface or 400 on the right surface.

[0068] refer to Figure 12 The right disk 244 includes a disk body 248 having a bottom surface 256. The bottom surface 256 defines a fourth hole or lower hole 404 intersecting the first axis 348 and defines a third cavity or lower cavity 408. The bottom surface 256 contacts the circumferential surface 260 along a second edge or lower edge 412 and is spaced apart from the lower hole 404. The lower edge 412 is circular. In some embodiments, the lower hole 404 is cylindrical and is a "blind hole." That is, the lower hole 404 does not extend through the right disk 244 to the top surface 252.

[0069] refer to Figure 13 and Figure 14 The cover 416 is configured to partially retain the right disc 244 (see Figure 11 and Figure 12 The lid 416 has a fourth body (or lid body) 420, which has a seventh surface (or upper surface) 424. Figure 13 ) and the eighth surface (or lower surface) 428 ( Figure 14The lid body 420 has a first portion (or narrow portion) 432 and a second portion (or wide portion) 436. The wide portion 436 is wider than the narrow portion 432 and includes a plurality of skirts 440 that project from the lower surface 428 along a portion of a third edge (or lid edge) 444 defining the periphery of the lower surface 428. The narrow portion 432 includes a second post (or lid post) 448. In some embodiments, the lid post 448 is cylindrical, projects further from the upper surface 424 than the plurality of skirts 440, and is centered on a second axis 452.

[0070] refer to Figure 15 and Figure 16 The housing 456 has a fifth body (or housing body) 460, which has a ninth surface (or housing surface) 464 defined by a periphery defined by a fourth edge (or housing edge) 468. The housing surface 464 defines a third portion (or lower portion) 472 and a fourth portion (or upper portion) 476, which are separated by a fifth portion (or joining portion) 480. The lower portion 472 has a third post (or housing post) 484 projecting from the housing surface 464. In some embodiments, the housing post 484 is cylindrical, and a third axis 492 extends from its center. The upper portion 476 includes a plurality of sidewalls 496 projecting from the housing surface 464 along a portion of the housing edge 468. The upper portion 476 includes a first region (or outer region) 500, a second region (or inner region) 504, and a third region (or upper region) 508. The outer region 500 includes a side hole 316 defining a side channel 320, at least one of a plurality of sidewalls 496, and a guide plate 512 located between the outer region 500 and the inner region 504. The guide plate 512 protrudes from the housing surface 464 and has a tenth surface (or guide plate surface) 516 facing the side hole 316 at a first acute angle 520. The inner region 504 includes at least one of the plurality of sidewalls 496 and contacts the engagement portion 480, the upper region 508, and the guide plate 512. The upper region 508 includes at least one of the plurality of sidewalls 496 and contacts the inner region 504.

[0071] refer to Figure 17The housing 456 is shown with a spring 524 positioned in an upper region 508 of the upper portion 476, a right disc 244 held on the lower portion 472, and a tension lock 528 with a release actuator 328. The tension lock 528 has a sixth body (or lock body) 532 defining an engaging body 536, a guide body 540, and a narrow body 544 connecting the engaging body 536 to the guide body 540. The guide body 540 is configured to be positioned in an outer region 500 and has a release actuator 328 projecting toward or through a side hole 316. The guide body 540 defines an eleventh surface (or guide surface) 548. The guide plate surface 516 of the guide plate 512 is configured to face the guide surface 548 of the guide body 540. The engaging body 536 has a twelfth surface (or spring seat surface) 552 facing the spring 524 and away from the lower portion 472, such that the spring 524 can press against or compress the engaging body 536. The engaging body 536 has a thirteenth surface (or engaging surface) 556, which has a closing mechanism manifested as a plurality of engaging teeth 564 facing the lower portion 472.

[0072] When the plurality of engagement teeth 564 engage or mesh with the plurality of disk teeth 272 of the right disk 244, the right disk 244 is in a locking configuration 568. The spring 524 biases the tension lock 528 into contact with the right disk 244. The right disk 244 is held within the lower portion 472 of the housing 456 by inserting or retaining the housing post 484 of the housing 456 within the lower cavity 408 of the lower bore 404 of the right disk 244. In the locking configuration 568, the third axis 492 of the housing post 484 of the housing 456 is aligned with the first axis 348 of the right disk 244. In the locking configuration 568, the release actuator 328 of the tension lock 528 protrudes beyond the housing 456 and the side bore 316. Multiple engagement teeth 564 are configured such that multiple disc teeth 272 can overcome the biasing force of engaging with multiple engagement teeth 564 by overcoming the compression of spring 524, and allow each of the multiple disc teeth 272 to rotate relative to each of the multiple engagement teeth 564. For this purpose, the multiple engagement teeth 564 and / or the multiple disc teeth 272 may include an inclined or ramped surface forming a cam interface 569 to provide a mechanical advantage in helping to overcome the biasing force of spring 524. The cam interface 569 may be provided only on one side of the teeth 564, 272 to correspond to rotation in the direction that causes the shoelace 280 to further wind around the shoelace retainer 276 in the locking configuration 568, thereby allowing tightening adjustment by rotation in that winding direction. Such a cam surface 569 may not be formed on the opposite sides of the teeth 564, 272, thereby preventing or inhibiting loosening or loosening adjustment caused by rotation of the right disc 244 in the opposite direction in the locking configuration 568.

[0073] In some embodiments, the locking configuration 568 may be configured to require considerable force to overcome the spring 524, such that once the tension on the shoelace 280 is set, the midfoot region 110 (see...) Figure 4 The magnitude of the downward force 288 on the right disc 244 can be set and then maintained. Thus, in the locking configuration 568, by operating the tension lock 528, the compression applied to the midfoot region 110 by the downward force or compressive force 288 can be selectively adjusted, set, and maintained. Furthermore, during rotation in the winding direction, the biased engagement between the multiple engagement teeth 564 and the multiple disc teeth 272 produces audible feedback, such as a clicking sound. The audible feedback is a function of the spring 524, which biases or presses the multiple engagement teeth 564 against the multiple disc teeth 272. The audible feedback can indicate to the user that the right disc 244 is rotating in the winding direction, and therefore the tightness of the footwear 200 is increasing.

[0074] refer to Figure 18 The multiple engaging teeth 564 of the tension lock 528 can be moved away from the multiple disc teeth 272 by applying a first force (or actuating force) 572 (see Figure 17 The engagement of the engagement body 536 involves a first force (or actuating force) 572 directed toward the release actuator 328 in a direction toward the inner region 504. Therefore, the release actuator 328 is pushed toward the inner region 504 by the actuating force 572. In some embodiments, the release actuator 328 may be fully pressed into the outer region 500, and in some embodiments, the release actuator 328 may be partially pressed into the outer region 500 by the actuating force 572. The actuating force 572 transmits force to the guide body 540, causing the guide surface 548 to contact the guide plate surface 516 of the guide plate 512 and then slide along the guide plate surface 516, thereby moving the engagement body 536 toward the spring 524 and away from the lower portion 472 with a second force (or unlocking force) 576. The engagement body 536 is configured to be mounted within a plurality of sidewalls 496 such that, when subjected to the actuating force 572 and the unlocking force 576, the engagement body 536 can move away from the outer region 500 and toward the upper region 508. When the engaging body 536 overcomes the biasing force of the spring 524, the right disk 244 is in the unlocked configuration 580, and the plurality of engaging teeth 564 engage with the right disk 244 (see...). Figure 17 The multiple disc teeth 272 disengage from engagement.

[0075] In the unlocked configuration 580, adjusting the tension of shoelace 280 does not require a lot of force, making shoelace 280 (see...) Figure 10 The tension on the ) can be adjusted, thereby changing the midfoot region 110 (see) before engaging multiple engagement teeth 564. Figure 4The magnitude of the downward force 288 on the laces 580 is determined, allowing the downward force 288 to be set or adjusted as needed. Thus, in the unlocked configuration 580, the pressure applied to the midfoot region 110 by the downward force 288 can be selectively adjusted by disengaging from the multiple engagement teeth 564 of the tension lock 528. When the multiple engagement teeth 564 are in the unlocked configuration 580, if the laces 280 are wound around the lace retainer 276 to form a coil 332, the potential energy 388 stored in the laces 280 is released to help the laces 280 unwind around the circumference 376 of the lace retainer 276, and thus to help the right disc 244 unwind. This accelerates the release of pressure on the midfoot region 110.

[0076] refer to Figure 19 and Figure 20 The figure shows a cross-section of the lid 416, the right disc 244, and the housing 456, with the first axis 348 of the right disc 244 aligned with the second axis 452 of the lid 416 and the third axis 492 of the housing 456. The lid 416, the right disc 244, and the housing 456 are configured to be assembled together and inserted into the midsole 164 (see figure). Figure 4 The cover 416 is positioned within the main cavity 240 formed by the rear hole 232. The cover post 448 of the cover 416 is configured to be mounted within the upper cavity 368 of the right disk 244, and the housing post 484 of the housing 456 is configured to be mounted within the lower cavity 408 of the right disk 244. Multiple skirts 440 of the cover 416 are configured to secure multiple sidewalls 496 of the housing 456. The right disk 244 is freely rotatable about a first axis 348 while being confined, held, and fixed between the cover 416 and the housing 456. At least a portion of the multiple disk teeth 272 emerge from the middle bottom 224 (see...). Figure 4 The main cavity 240 protrudes outward. When the second axis 452 and the third axis 492 are aligned, the narrow portion 432 of the cover 416 is aligned with the lower portion 472 of the housing 456. When the multiple skirts 440 are fixed to the multiple sidewalls 496, the wide portion 436 of the cover 416 is aligned with the upper portion 476 of the housing 456.

[0077] refer to Figure 20 When the cover 416, housing 456, and right disc 244 are assembled together, this assembly constitutes the disc heel fastener 584. When assembled into the disc heel fastener 584, the volume of space between the lower surface 428 and the top surface 252 defines a fourth cavity (or shoelace cavity) 588. When the right disc 244 is subjected to rotational force 312 (see...) Figure 6 As the shoelaces 280 rotate along, for example, a first direction or a clockwise direction CW (when viewed from above and below the footwear 200), they surround the circumference 376 of the shoelace fastener 276 within the shoelace cavity 588 (see...). Figure 8 and Figure 9The heel fastener 584 extends to increase the size of the loop 332 of the lace 280 around the circumference 376 of the lace fastener 276. Furthermore, when the release mechanism 324 is actuated and the right disc 244 is in the unlocked configuration, a rotational force 312 can be applied in a second direction or counterclockwise (viewed from above the footwear 200) to decrease the size of the loop 332 of the lace 280 around the circumference 376 of the lace fastener 276. Therefore, the disc heel fastener 584 provides a way to tighten and loosen the midfoot area 110 of the footwear 200 without tying any laces.

[0078] Furthermore, due to the spacing and arrangement of the plurality of teeth 272 around the circumference of the right disc 244, further rotation in the first direction CW allows for incremental adjustment when tightening the footwear 200 according to the user's preference and comfort. In some embodiments, the magnitude of the incremental adjustment is the radial spacing and dimension of the plurality of teeth 272 of the right disc 244 and / or the left disc 296, as well as the plurality of engaging teeth 564 (see...). Figure 17 The lateral spacing and dimensions of the teeth 272 are functions of the lateral spacing and dimensions of the teeth 564. For example, smaller or finer incremental adjustments can be provided by reducing the size of the radial spacing of the multiple teeth 272 and the lateral spacing of the multiple engagement teeth 564. It should be understood that when the compression force 288 is applied to the user's foot, the footwear 200 is considered to be tightened or adjusted to a tightened configuration. As described herein, the footwear 200 can be incrementally adjusted to increase the compression force 288 in the tightened configuration. Furthermore, when the compression force 288 is not applied or is not perceived by the user's foot, or when the footwear 200 is in an unlocked configuration and the compression force 288 is easily overcome, the footwear 200 is considered to be in a loosened configuration, thereby allowing the user to remove the footwear 200 from their foot.

[0079] It should be understood that the operation of the left disc 296 is similar to that of the right disc 244, but in a mirror manner. In some embodiments, the left disc 296 rotates along the second direction CCW to tighten the shoe 200, and when in an unlocked configuration, rotates along the first direction CW to loosen the shoe 200. However, within the scope of this disclosure, the first direction CW and the second direction CCW can be reversed to achieve tightening or unscrewing of the right disc 244 and the left disc 296. In some embodiments, the right disc 244 and the left disc 296 of the shoe 200 are not mirror-symmetrical, but are both configured to tighten by rotation along the first direction CW or the second direction CCW.

[0080] According to some embodiments of this disclosure, a user can place one of the right discs 244 or the left disc 296 in an unlocked configuration and then apply a rotational force 312 to the other of the right discs 244 or the left disc 296 to adjust the tightness. For example, the right disc 244 can be unlocked by actuation of the release mechanism 324, and then the right disc 244 is tightened by engaging a plurality of teeth 272 of the left disc 296 with a plurality of teeth 272 of the right disc 244 as the left disc 296 moves in the forward direction, such as by scraping or sliding, i.e., from the heel end 148 to the toe end 142. Because the left disc 296 is in a locked configuration, rotation of the left disc 296 in the first direction CW is prevented, thereby allowing the user to tighten one foot at a time without having to bend over to tie shoelaces or rotate the discs 244, 296 by hand.

[0081] In another example, the right disc 244 and the left disc 296 operate in opposite directions to provide one disc to move backward against the other disc for tightening. For example, the right disc 244 is configured to rotate in a second direction (CCW) to tighten the shoe 200, and when in the unlocked configuration, to rotate in a first direction (CW) to loosen the shoe 200. Therefore, the left disc 296 is configured to rotate in the first direction (CW) to tighten the shoe 200, and when in the unlocked configuration, to rotate in the second direction (CCW) to loosen the shoe 200. In this way, the user can place one foot on the ground and transfer their weight onto that foot while the other foot is suspended or lightly touching the ground, positioning one disc in front of the other disc, and then sliding the forward-positioned disc backward, i.e., moving it from the toe end 142 to the heel end 148, to tighten the foot placed on the ground using the suspended foot. In some embodiments, the left disc 296 is placed on the ground, and the right disc 244 is positioned in front of it, for example, adjacent to the midfoot region 110 or forefoot region 108 of the shoe 200 on the left foot. This causes the rearward movement of the right disc 244 or other parts of the shoe 200 on the right foot to apply a rotational force 312 to the left disc 296, tightening the shoe 200 on the left foot. A mirror operation can be performed to tighten the shoe 200 on the right foot. This allows the user to quickly adjust the tightness of one or both shoes 200, which can be advantageous in situations where time is limited, such as during a competition.

[0082] It is also conceivable that the release mechanism 324 could be positioned within the midfoot region 110 of the instep region 160 of the sole structure 104, allowing the user to actuate the release mechanism 324 and unlock one foot with the other foot, thereby reducing the need for the user to manually actuate the release mechanism. Therefore, the aforementioned operation of tightening the shoe 200 can be reversed to loosen the shoe 200. In this way, the user can quickly remove the shoe 200 from one or both feet without bending over and manually operating the shoe 200, which could be advantageous for users who have difficulty or are unable to do so. Furthermore, removing the shoe 200 without manual operation can improve cleanliness, for example, by enabling the user to quickly unfasten and remove the shoe 200 before entering the home.

[0083] It is also conceivable that any of discs 244 and 296 may be provided with or modified to include a closure mechanism similar to those disclosed and described 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. It is also conceivable that discs 244 and 296 may be modified to include a closure mechanism to replace or supplement the head, thereby providing further tightening functionality when used with shoelaces 280 and mounted on footwear 200 of this disclosure.

[0084] In other embodiments, other configurations may also be possible. For example, certain features and combinations of features presented for specific embodiments in the above discussion may be suitably used in other embodiments and combinations.
