Description
- This application claims the benefit of and priority to U.S. Provisional Application No. 63/418,850, filed on Oct. 24, 2022, which is incorporated by reference herein in its entirety.
- Not applicable
- Not applicable
- The present disclosure relates generally to an article of footwear including a closure system.
- Many conventional shoes or other articles of footwear generally comprise an upper and a sole attached to a lower end of the upper. Conventional shoes further include an internal space, i.e., a void or cavity, which is created by interior surfaces of the upper and sole, that receives a foot of a user before securing the shoe to the foot. The sole is attached to a lower surface or boundary of the upper and is positioned between the upper and the ground. As a result, the sole typically provides stability and cushioning to the user when the shoe is being worn. In some instances, the sole may include multiple components, such as an outsole, a midsole, and a top portion. The outsole may provide traction to a bottom surface of the sole, and the midsole may be attached to an inner surface of the outsole, and may provide cushioning or added stability to the sole. For example, a sole may include a particular foam material that may increase stability at one or more desired locations along the sole, or a foam material that may reduce stress or impact energy on the foot or leg when a user is running, walking, or engaged in another activity. The sole may also include additional components, such as plates, embedded with the sole to increase the overall stiffness of the sole and reduce energy loss during use.
- The upper generally extends upward from the sole and defines an interior cavity that completely or partially encases a foot. In most cases, the upper extends over the instep and toe regions of the foot, and across medial and lateral sides thereof. Many articles of footwear may also include a tongue that extends across the instep region to bridge a gap between edges of medial and lateral sides of the upper, which define an opening into the cavity. The tongue may also be disposed below a lacing system and between medial and lateral sides of the upper, to allow for adjustment of shoe tightness. The tongue may further be manipulatable by a user to permit entry or exit of a foot from the internal space or cavity. In addition, the lacing system may allow a user to adjust certain dimensions of the upper or the sole, thereby allowing the upper to accommodate a wide variety of foot types having varying sizes and shapes.
- The upper of many shoes may comprise a wide variety of materials, which may be utilized to form the upper and chosen for use based on one or more intended uses of the shoe. The upper may also include portions comprising varying materials specific to a particular area of the upper. For example, added stability may be desirable at a front of the upper or adjacent a heel region to provide a higher degree of resistance or rigidity. In contrast, other portions of a shoe may include a soft woven textile to provide an area with stretch-resistance, flexibility, air-permeability, or moisture-wicking properties.
- However, in many cases, articles of footwear having uppers with an increased comfort and better fit are desired, along with improved closure mechanisms.
- An article of footwear, as described herein, may have various configurations. The article of footwear may have an upper and a sole structure connected to the upper.
- In one embodiment, a fastening system for an article of footwear comprises a fastening mechanism, a lace, and a cable. The fastening mechanism includes an upper cover that is rotatably coupled to a chassis. The lace is configured to be operably coupled to an upper of the article of footwear and the fastening mechanism. The cable is attached to the upper cover and is configured to be rotated relative to the chassis about a rotational axis to adjust the footwear between a loosened configuration and a tightened configuration. The fastening mechanism is tightened by actuating the cable and is loosened by rotating the upper cover counterclockwise.
- In another embodiment, a fastening system for an article of footwear comprises a fastening mechanism. The fastening mechanism includes an upper cover, a chassis, a floating latch, an affixed latch, a cable, and a pinion-spool assembly. A lace is configured to be operably engaged with an upper of the footwear and the fastening mechanism is configured to be actuated to adjust the footwear from a loosened configuration to a tightened configuration.
- In yet another embodiment, a method of operating a fastening system is introduced. The steps comprise providing an article of footwear that comprises an opening that is configured to receive a foot and then providing a fastening mechanism comprising a first actuation mechanism to adjust the tightness of the footwear, and providing a second actuation mechanism to further adjust the tightness of the footwear. The second and the first actuation mechanisms are configured to be operably engaged with a pinion-spool assembly. The first actuation mechanism is operably engaged with a spring element and the spring element adjusts a tension between a lace that is operably connected with the pinion-spool assembly. The pinion-spool assembly is rotated in a first direction to adjust the fastening mechanism to a tightened configuration. The pinion-spool assembly is rotated in a second direction to adjust the fastening mechanism to a loosened configuration.
- Other aspects of the article of footwear, including features and advantages thereof, will become apparent to one of ordinary skill in the art upon examination of the figures and detailed description herein. Therefore, all such aspects of the article of footwear are intended to be included in the detailed description and this summary.

FIGS. 1-3 depict an exemplary embodiment of an article offootwear 100 including an upper 102 and asole structure 104. The upper 102 is attached to thesole structure 104 and together define an interior cavity 106 (seeFIGS. 2 and 3 ) into which a foot may be inserted. For reference, the article offootwear 100 defines aforefoot region 108, amidfoot region 110, and a heel region 112 (seeFIGS. 2 and 3 ). Theforefoot region 108 generally corresponds with portions of the article offootwear 100 that encase portions of the foot that includes the toes, the ball of the foot, and joints connecting the metatarsals with the toes or phalanges. Themidfoot region 110 is proximate and adjoining theforefoot region 108, and generally corresponds with portions of the article offootwear 100 that encase the arch of the foot, along with the bridge of the foot. Theheel region 112 is proximate and adjoining themidfoot region 110 and generally corresponds with portions of the article offootwear 100 that encase rear portions of the foot, including the heel or calcaneus bone, the ankle, and/or the Achilles tendon. - Many conventional footwear uppers are formed from multiple elements, e.g., textiles, polymer foam, polymer sheets, leather, and synthetic leather, which are joined through bonding or stitching at a seam. In some embodiments, the upper 102 of the article of
footwear 100 is formed from a knitted structure or knitted components. In various embodiments, a knitted component may incorporate various types of yarn that may provide different properties to an upper. For example, one area of the upper 102 may be formed from a first type of yarn that imparts a first set of properties, and another area of the upper 102 may be formed from a second type of yarn that imparts a second set of properties. Using this configuration, properties of the upper 102 may vary throughout the upper 102 by selecting specific yarns for different areas of the upper 102. - With reference to the material(s) that comprise the upper 102, the specific properties that a particular type of yarn will impart to an area of a knitted component may at least partially depend upon the materials that form the various filaments and fibers of the yarn. For example, cotton may provide a soft effect, biodegradability, or a natural aesthetic to a knitted material. Elastane and stretch polyester may each provide a knitted component with a desired elasticity and recovery. Rayon may provide a high luster and moisture absorbent material, wool may provide a material with an increased moisture absorbance, nylon may be a durable material that is abrasion-resistant, and polyester may provide a hydrophobic, durable material.
- Other aspects of a knitted component may also be varied to affect the properties of the knitted component and provide desired attributes. For example, a yarn forming a knitted component may include monofilament yarn or multifilament yarn, or the yarn may include filaments that are each formed of two or more different materials. In addition, a knitted component may be formed using a particular knitting process to impart an area of a knitted component with particular properties. Accordingly, both the materials forming the yarn and other aspects of the yarn may be selected to impart a variety of properties to particular areas of the upper 102.
- In some embodiments, an elasticity of a knit structure may be measured based on comparing a width or length of the knit structure in a first, non-stretched state to a width or length of the knit structure in a second, stretched state after the knit structure has a force applied to the knit structure in a lateral direction. In further embodiments, the upper 102 may also include additional structural elements. For example, in some embodiments, a heel plate or cover (not shown) may be provided on the
heel region 112 to provide added support to a heel of a user. In some instances, other elements, e.g., plastic material, logos, trademarks, etc., may also be applied and fixed to an exterior surface using glue or a thermoforming process. In some embodiments, the properties associated with the upper 102, e.g., a stitch type, a yarn type, or characteristics associated with different stitch types or yarn types, such as elasticity, aesthetic appearance, thickness, air permeability, or scuff-resistance, may be varied. - Referring again to
FIG. 1 , thesole structure 104 is connected or secured to the upper 102 and extends between a foot of a user and the ground when the article offootwear 100 is worn by the user. Thesole structure 104 may include one or more components, which may include an outsole, a midsole, a heel, a panel, and/or an insole. For example, in some embodiments, a sole structure may include an outsole that provides structural integrity to the sole structure, along with providing traction for a user, a midsole that provides a cushioning system, and an insole that provides support for an arch of a user. In addition, the insole may be a strobel board, a forefoot board, a lasting board, etc., or a combination thereof, and the insole may be provided between the upper 102 and thesole structure 104, or the insole may be provided as part of the upper 102. - Furthermore, the insole can be positioned within the
interior cavity 106 of the upper 102, which can be in direct contact with a user's foot while an article offootwear 100 is being worn. Moreover, the upper 102 may also include a liner (not shown) that can increase comfort, for example, by reducing friction between the foot of the user and the upper 102, thesole structure 104, the insole, or the like, and/or by providing moisture wicking properties. The liner may line the entirety of theinterior cavity 106 or only a portion thereof. In some embodiments, a binding (not shown) may surround an opening of theinterior cavity 106 to secure the liner to the upper 102 and/or to provide an aesthetic element on the article offootwear 100. - Referring to
FIGS. 2 and 3 , the article offootwear 100 also defines alateral side 116 and amedial side 118. When a user is wearing the shoes, thelateral side 116 corresponds with an outside-facing portion of the article offootwear 100 while themedial side 118 corresponds with an inside-facing portion of the article offootwear 100. As such, the article offootwear 100 has opposinglateral sides 116 andmedial sides 118. Themedial side 118 and thelateral side 116 adjoin one another along a longitudinal central plane orcentral axis 120 of the article offootwear 100, which is coplanar with the longitudinal axis L ofFIG. 1 . As will be further discussed herein, the longitudinal central plane orcentral axis 120 may demarcate a central, intermediate axis between themedial side 118 and thelateral side 116 of the article offootwear 100. Put differently, the longitudinal plane orcentral axis 120 may extend between a rear,proximal end 122 of the article offootwear 100 and a front,distal end 124 of the article offootwear 100 and may continuously define a middle of aninsole 126, thesole structure 104, and/or the upper 102 of the article offootwear 100, i.e., the longitudinal plane orcentral axis 120 is a straight axis extending through the rear,proximal end 122 of theheel region 112 to the front,distal end 124 of theforefoot region 108. - Unless otherwise specified, and referring to
FIGS. 2 and 3 , the article offootwear 100 may be defined by theforefoot region 108, themidfoot region 110, and theheel region 112. Theforefoot region 108 may generally correspond with portions of the article offootwear 100 that encase portions of afoot 128 that include the toes orphalanges 130, the ball of thefoot 132, and one or more of thejoints 134 that connect themetatarsals 136 of thefoot 128 with the toes orphalanges 130. Themidfoot region 110 is proximate and adjoins theforefoot region 108. Themidfoot region 110 generally corresponds with portions of the article offootwear 100 that encase an arch of afoot 128, along with a bridge of thefoot 128. Theheel region 112 is proximate to themidfoot region 110 and adjoins themidfoot region 110. Theheel region 112 generally corresponds with portions of the article offootwear 100 that encase rear portions of thefoot 128, including the heel orcalcaneus bone 138, the ankle (not shown), and/or the Achilles tendon (not shown). - Still referring to
FIGS. 2 and 3 , theforefoot region 108, themidfoot region 110, theheel region 112, themedial side 118, and thelateral side 116 are intended to define boundaries or areas of the article offootwear 100. To that end, theforefoot region 108, themidfoot region 110, theheel region 112, themedial side 118, and thelateral side 116 generally characterize sections of the article offootwear 100. Certain aspects of the disclosure may refer to portions or elements that are coextensive with one or more of theforefoot region 108, themidfoot region 110, theheel region 112, themedial side 118, and/or thelateral side 116. Further, both the upper 102 and thesole structure 104 may be characterized as having portions within theforefoot region 108, themidfoot region 110, theheel region 112, and/or along themedial side 118 and/or thelateral side 116. Therefore, the upper 102 and thesole structure 104, and/or individual portions of the upper 102 and thesole structure 104, may include portions thereof that are disposed within theforefoot region 108, themidfoot region 110, theheel region 112, and/or along themedial side 118 and/or thelateral side 116. - Still referring to
FIGS. 2 and 3 , theforefoot region 108, themidfoot region 110, theheel region 112, themedial side 118, and thelateral side 116 are shown in detail. Theforefoot region 108 extends from atoe end 140 to awidest portion 142 of the article offootwear 100. Thewidest portion 142 is defined or measured along afirst line 144 that is perpendicular with respect to thecentral axis 120 that extends from a distal portion of thetoe end 140 to a distal portion of aheel end 146, which is opposite thetoe end 140. Themidfoot region 110 extends from thewidest portion 142 to athinnest portion 148 of the article offootwear 100. Thethinnest portion 148 of the article offootwear 100 is defined as the thinnest portion of the article offootwear 100 measured across asecond line 150 that is perpendicular with respect to thecentral axis 120. Theheel region 112 extends from thethinnest portion 148 to theheel end 146 of the article offootwear 100. - It should be understood that numerous modifications may be apparent to those skilled in the art in view of the foregoing description, and individual components thereof, may be incorporated into numerous articles of footwear. Accordingly, aspects of the article of
footwear 100 and components thereof, may be described with reference to general areas or portions of the article offootwear 100, with an understanding the boundaries of theforefoot region 108, themidfoot region 110, theheel region 112, themedial side 118, and/or thelateral side 116 as described herein may vary between articles of footwear. However, aspects of the article offootwear 100 and individual components thereof, may also be described with reference to exact areas or portions of the article offootwear 100 and the scope of the appended claims herein may incorporate the limitations associated with these boundaries of theforefoot region 108, themidfoot region 110, theheel region 112, themedial side 118, and/or thelateral side 116 discussed herein. - Still referring to
FIGS. 2 and 3 , themedial side 118 begins at the distal,toe end 140 and bows outward along an inner side of the article offootwear 100 along theforefoot region 108 toward themidfoot region 110. Themedial side 118 reaches thefirst line 144, at which point themedial side 118 bows inward, toward the longitudinal,central axis 120. Themedial side 118 extends from thefirst line 144, i.e., thewidest portion 142, toward thesecond line 150, i.e., thethinnest portion 148, at which point themedial side 118 enters into themidfoot region 110, i.e., upon crossing thefirst line 144. Once reaching thesecond line 150, themedial side 118 bows outward, away from the longitudinal,central axis 120, at which point themedial side 118 extends into theheel region 112, i.e., upon crossing thesecond line 150. Themedial side 118 then bows outward and then inward toward theheel end 146, and terminates at a point where themedial side 118 meets the longitudinal,central axis 120. - The
lateral side 116 also begins at the distal,toe end 140 and bows outward along an outer side of the article offootwear 100 along theforefoot region 108 toward themidfoot region 110. Thelateral side 116 reaches thefirst line 144, at which point thelateral side 116 bows inward, toward the longitudinal,central axis 120. Thelateral side 116 extends from thefirst line 144, i.e., thewidest portion 142, toward thesecond line 150, i.e., thethinnest portion 148, at which point thelateral side 116 enters into themidfoot region 110, i.e., upon crossing thefirst line 144. Once reaching thesecond line 150, thelateral side 116 bows outward, away from the longitudinal,central axis 120, at which point thelateral side 116 extends into theheel region 112, i.e., upon crossing thesecond line 150. Thelateral side 116 then bows outward and then inward toward theheel end 146, and terminates at a point where thelateral side 116 meets the longitudinal,central axis 120. - Still referring to
FIGS. 2 and 3 , the upper 102 extends along thelateral side 116 and themedial side 118, and across theforefoot region 108, themidfoot region 110, and theheel region 112 to house and enclose a foot of a user. When fully assembled, the upper 102 also includes aninterior surface 162 and anexterior surface 164. Theinterior surface 162 faces inward and generally defines theinterior cavity 106, and theexterior surface 164 of the upper 102 faces outward and generally defines an outer perimeter or boundary of the upper 102. The upper 102 also includes anopening 166 that is at least partially located in theheel region 112 of the article offootwear 100, which provides access to theinterior cavity 106 and through which a foot may be inserted and removed. In some embodiments, the upper 102 may also include aninstep region 168 that extends from theopening 166 in theheel region 112 over an area corresponding to an instep of a foot to an area proximate theforefoot region 108. Theinstep region 168 may comprise an area similar to where atongue 170 of the present embodiment is disposed. In some embodiments, the upper 102 does not include thetongue 170, i.e., the upper 102 is tongueless. - In the illustrated embodiment, the
sole structure 104 includes amidsole 172 and anoutsole 174. Theoutsole 174 may define a bottom end orbottom surface 176 of thesole structure 104 across theheel region 112, themidfoot region 110, and theforefoot region 108. Further, theoutsole 174 may be a ground-engaging portion or include a ground-engaging surface of thesole structure 104 and may be opposite of the insole thereof. As illustrated inFIG. 1 , thebottom surface 176 of theoutsole 174 may include atread pattern 178 that can include a variety of shapes and configurations. Theoutsole 174 may be formed from one or more materials to impart durability, wear-resistance, abrasion resistance, or traction to thesole structure 104. In some embodiments, theoutsole 174 may be formed from any kind of elastomer material, e.g., rubber, including thermoset elastomers or thermoplastic elastomers, or a thermoplastic material, e.g., thermoplastic polyurethane (TPU). In some embodiments, theoutsole 174 may define a shore A hardness up to 95. In addition, theoutsole 174 may be manufactured by a process involving injection molding, vulcanization, printing layer by layer, i.e., additive manufacturing systems or methods, and the like. - Still referring to
FIG. 1 , themidsole 172 may be individually constructed from a thermoplastic material, such as polyurethane (PU), for example, and/or an ethylene-vinyl acetate (EVA), copolymers thereof, or a similar type of material. In other embodiments, themidsole 172 may be an EVA-Solid-Sponge (“ESS”) material, an EVA foam (e.g., PUMA® ProFoam Lite™, IGNITE Foam), polyurethane, polyether, an olefin block copolymer, organosheets, a thermoplastic material (e.g., a thermoplastic polyurethane, a thermoplastic elastomer, a thermoplastic polyolefin, etc.), or a supercritical foam. Themidsole 172 may be a single polymeric material or may be a blend of materials, such as an EVA copolymer, a thermoplastic polyurethane, a polyether block amide (PEBA) copolymer, and/or an olefin block copolymer. One example of a PEBA material is PEBAX®. In some embodiments, themidsole 172 is manufactured by a process involving injection molding, vulcanization, printing layer by layer, i.e., additive manufacturing systems or methods, and the like. - In embodiments where the
midsole 172 is formed from a supercritical foaming process, the supercritical foam may comprise micropore foams or particle foams, such as a TPU, EVA, PEBAX®, or mixtures thereof, manufactured using a process that is performed within an autoclave, an injection molding apparatus, or any sufficiently heated/pressurized container that can process the mixing of a supercritical fluid (e.g., CO2, N2, or mixtures thereof) with a material (e.g., TPU, EVA, polyolefin elastomer, or mixtures thereof) that is preferably molten. During an exemplary process, a solution of supercritical fluid and molten material is pumped into a pressurized container, after which the pressure within the container is released, such that the molecules of the supercritical fluid rapidly convert to gas to form small pockets within the material and cause the material to expand into a foam. In further embodiments, themidsole 172 may be formed using alternative methods known in the art, including the use of an expansion press, an injection machine, a pellet expansion process, a cold foaming process, a compression molding technique, die cutting, or any combination thereof. For example, themidsole 172 may be formed using a process that involves an initial foaming step in which supercritical gas is used to foam a material and then compression molded or die cut to a particular shape. -
FIG. 4 depicts a schematic representation of an article offootwear 200 having afastening system 204 that includes afastening mechanism 208 and alace 212 that is operably coupled to the upper 102 and thefastening mechanism 208 to tighten and/or loosen thefootwear 200.

A portion of the X-axis that intersects the center point CP2 and the longitudinal axis of the static bolt LAS defines a reference plane orreference axis 464 between the second and thethird quadrants initial angle 462 of theinitial actuation position 450 is measured as the angle between the center point CP2 of thestatic bolt 338 and the center point CP1 of thedynamic bolt 246 in theinitial actuation position 450 relative to the central axis CA. Put another way, theinitial angle 462 represents the angular position of the center point CP2 of thedynamic bolt 246 in theinitial actuation position 450 relative to thereference axis 464. Theinitial angle 462 of an initial position may be between about 25 degrees and about 89 degrees, or between about 30 degrees and about 85 degrees, or between about 70 degrees and about 80 degrees. In some instances, theinitial angle 462 is between about 80 degrees and about 89 degrees, or about 85 degrees. -
FIG. 12 depicts anintermediate actuation position 480 of thefastening mechanism 208. Thecable 214 is configured to be pulled through thereceptacle 260, thereby moving theupper cover 220 of thefastening mechanism 208 in a clockwise direction about the central axis CA.

The floatinglatch 322 rotates along a clockwise direction with thedynamic bolt 246, and the longitudinal axis of the dynamic bolt LAD moves along the first andfourth quadrants third quadrant 456. Anintermediate angle 482 is measured as the angle between the center point CP2 of thestatic bolt 338 and the center point CP1 of thedynamic bolt 246 in theintermediate actuation position 480 relative to the central axis CA. Put another way, theintermediate angle 482 represents the angular position of the center point CP2 of thedynamic bolt 246 in theintermediate actuation position 480 relative to thereference axis 464. Theintermediate angle 482 of an intermediate position may be between about 90 degrees and about 269 degrees. -
FIG. 13 depicts afinal actuation position 500 of thefastening mechanism 208. Thecable 214 is configured to be pulled through thereceptacle 260, thereby moving theupper cover 220 of thefastening mechanism 208 in a clockwise direction about the central axis CA. The longitudinal axis LAD of thedynamic bolt 246 is coupled to the floatinglatch 322 that is disposed within thethird quadrant 456 of thefastening mechanism 208. Afinal angle 502 of a final position is measured as the angle between the center point CP2 of thestatic bolt 338 and the center point CP1 of thedynamic bolt 246 in thefinal actuation position 500 relative to the central axis CA. Put another way, thefinal angle 502 of a final position represents the angular position of the center point CP2 of thedynamic bolt 246 in thefinal actuation position 500 relative to thereference axis 464. Thefinal angle 502 of a final position can be between about 270 degrees and about 355 degrees. In some instances, thefinal angle 502 can be about 270 degrees, or about 280 degrees, or about 290 degrees, or about 320 degrees. Accordingly, the intermediate angle 482 (seeFIG. 12 ) is greater than theinitial angle 462, and thefinal angle 502 is greater than theintermediate angle 482. In some instances, thefinal angle 502 is between about 65% and about 95% greater than theinitial angle 462. -
FIG. 14 depicts amethod 600 of operating thefastening system 204 of an article offootwear 200. The operation of thefastening system 204 of thefootwear 200 is initiated by afirst step 610 that includes inserting the user's foot into theopening 166 of thefootwear 200. Once the user's foot is inserted into theopening 166, asecond step 620 is initiated by actuating a first mechanism to adjust a tightness of the footwear. The user pulls thecable 214 to overcome the spring force of thespring element 296 and disengage the floatinglatch 322 from the plurality ofteeth 362 of the pinion-spool assembly 360. As discussed above, the floatinglatch 322 is configured to abut the affixedlatch 320 and become disengaged at a position of at least about 270 degrees from thereference axis 464. In some embodiments, thelace 212 may be pulled iteratively and repeatedly for incremental adjustment. It is contemplated that the magnitude of incremental adjustment achieved by such repetitive pulling actuation is proportional to the size ofbarrel 364 of the pinion-spool assembly 360. In some instances, thebarrel 364 of the pinion-spool assembly 360 may be reduced, such that fine adjustment of the tightness is permitted, while requiring a larger number of iterative actuation. In some instances, thebarrel 364 of the pinion-spool assembly 360 may be increased, such that coarse adjustment of the tightness is permitted, while requiring a smaller number of iterative actuation. During athird step 630, the tightness of the footwear is assessed. The tightness of thefootwear 200 occurs due to the introduction of a spring load which may result in spinning of the pinion-spool assembly 360 in the counterclockwise direction that causes greater lengths of thelace 212 to become wrapped around thebarrel 364 of thespool 288. - A
fourth step 640 includes actuating a second mechanism, such as, e.g., pulling thecable 214 connected to theupper cover 220, to adjust the tightness of the footwear. In some embodiments, thestep 640 includes pulling thecable 214, which subsequently causes theupper cover 220 to rotate in a clockwise direction about the center axis CA. The floatinglatch 322 coupled to theupper cover 220 engages with at least one of the plurality ofteeth 362 of the pinion-spool assembly 360. The engagement between the at least one of the plurality ofteeth 362 and the floatinglatch 322 enables thespool 288 to incrementally wind lengths of thelace 212 around thebarrel 364 to incrementally adjust the tension of thelace 212 to tighten thefootwear 200. Adecision step 650 is reached by the user to determine whether a desired tightness has been achieved. If the desired tightness has not been achieved, the user may assess the tightness of thefootwear 200 and actuate the tightness of thefootwear 200 by returning to thethird step 630. Once the desired tightness of thelace 212 is reached, the affixedlatch 320 engages the at least one of the plurality ofteeth 362 of thepinion 324 holding the pinion-spool assembly 360 in place, and the tension between thespring element 296 in connection with the affixedlatch 320 and the floatinglatch 322 increases as the floatinglatch 322 also engages with the at least one of the plurality ofteeth 362 of thepinion 324. A partially closed position may be achieved by both the affixedlatch 320 and the floatinglatch 322 being engaged with the at least one of the plurality ofteeth 362 of thepinion 324, which increases the tension of thespring element 296. - A
user decision step 660 is reached in which the user determines whether or not to remove thefootwear 200. If the user decides to remove the footwear 200 (i.e., YES) atdecision step 660, afifth step 670 comprises loosening of thelace 212 to remove the user's foot from thefootwear 200 after use. The loosening of thelace 212 occurs as theupper cover 220 of thefastening mechanism 208 is turned counterclockwise. In other embodiments, the loosening of thelace 212 may be enabled by pulling thecable 214 connected to theupper cover 220. As theupper cover 220 rotates counterclockwise, the floatinglatch 322 coupled to theupper cover 220 disengages from the at least one of the plurality ofteeth 362 of thepinion 324 by sliding away from thepinion 324. Subsequently and simultaneously, thespool 288 of the pinion-spool assembly 360 partially releases thelace 212 from thefinal actuation position 500. As described above, thebolt head 402 of thedynamic bolt 246 couples the floatinglatch 322 andupper cover 220. In the illustrated embodiment, as thebolt head 402 of thedynamic bolt 246 abuts the affixedlatch 320 between thefirst arm 328 and thesecond arm 330, thedynamic bolt 246 generates a pushing force against thefirst arm 328 and thesecond arm 330 of the affixedlatch 320, which disengages the affixedlatch 320 from the plurality ofteeth 362 of thepinion 324 and relieves the tension of thelace 212. Asixth step 680 includes the removal of the user's foot from thefootwear 200. If the user decides not to remove the footwear 200 (i.e., NO) atdecision step 660, thefootwear 200 may be worn until it becomes necessary to repeat any of the steps 620-650 to adjust the tightness of thefootwear 200. - It is also contemplated that the
fastening mechanism 208, may be similar to those disclosed in U.S. Pat.
