Description

Article of footwear with automatic lacing system

Technical Field

The present disclosure relates generally to an article of footwear including an automatic lacing system including an electronic assembly for automatically tightening or loosening one or more laces.

Background

Many conventional shoes or articles of footwear generally include an upper and a sole attached to a lower end of the upper. Conventional shoes also include an interior void, or cavity, created by the upper and sole that receives the user's foot prior to securing the shoe to the foot. The sole is attached to a lower surface of the upper and is located between the upper and the ground. Accordingly, the sole generally provides stability and cushioning to a user when the footwear is worn and/or in use. In some cases, the sole may include multiple components, such as an outsole, a midsole, and an insole. The outsole may provide traction to a bottom surface of the sole, and the midsole may attach to an inner surface of the outsole and may provide cushioning and/or enhanced stability to the sole. For example, the sole may include a particular foam material that increases stability at one or more desired locations along the sole, or a foam material that may reduce stress or impact energy on the foot and/or leg while the user is running, walking, or engaged in additional activities.

The upper generally extends upward from the sole and defines an interior void that completely or partially encloses the foot. In most cases, the upper is positioned above the instep and toe areas of the foot and extends through the medial and lateral sides of the upper. Many articles of footwear may also include a tongue that extends through the instep area to bridge a gap between edges of the medial side and the lateral side of the upper, the gap defining an opening into the void. A tongue may also be disposed under the lacing system and between the medial side and the lateral side of the upper, the tongue being configured to allow for adjustment of the tightness of the footwear. The tongue may also be manipulated by a user to allow a foot to enter and/or exit from the interior space or cavity. In addition, the lacing system may allow a user to adjust certain dimensions of the upper and/or the sole, thereby allowing the upper to accommodate a variety of foot types having different sizes and shapes.

The upper may include a wide variety of materials, which may be selected based on one or more intended uses of the footwear. The upper may also include portions that include different materials for specific areas of the upper. For example, it may be desirable to enhance stability at the front of the upper or adjacent the heel area in order to provide a higher degree of resistance or stiffness. Rather, other portions of the footwear may include soft woven fabrics to provide zones of stretch resistance, flexibility, breathability, or moisture absorption.

Furthermore, lacing systems historically associated with typical footwear have included a single lace that passes through a plurality of eyelets in a criss-cross or parallel fashion. Historically, many shoes have included a lace that extends from one side of the upper to the other, i.e., from the medial side to the lateral side of the upper. The lace of each shoe is laced through the eyelets, and both ends of the lace extend out of the eyelets, so that a user can grasp the ends and tighten the shoe in such a way that the user looks fit. Some shoes do not require the user to tie the lace, but instead include a stretchable lace so that the lace can be stretched as the user puts on the shoe and can return to the original tightness once the user takes off the shoe.

Still further, some shoes do not include laces, such as a slider on the shoe, and some shoes include straps that can be adjusted to change the tightness of the shoe. For shoes that include laces, it is desirable to use a system that can automatically tie the lace, for example, where a user may desire to adjust the lace in different environments. An automatic lacing system that is difficult for users of ligatures for shoes (e.g., the elderly or infirm) may also be desirable. It may also be desirable to have a lacing system that includes a lace that does not apply force along the top of the foot; conversely, as the lace is tightened, forces are applied along the medial and lateral sides of the foot. Still further, it would be desirable to include a system by which a shoe can be automatically strapped via a graphical user interface displayed on a portable electronic device.

Accordingly, there is a need for an article of footwear having an upper that includes an automatic lacing system.

Fig. 1 depicts a shoe assembly 20 including shoes 22, each of which shoes 22 includes an automatic lacing system 24, a charger 26 for charging one or more batteries (not shown) disposed within each shoe 22, a charging box 28 for receiving the batteries (not shown) for charging when the batteries are removed from the shoes 22, and an electronic device 30, which may be a cell phone or tablet computer, which electronic device 30 may be used to send one or more signals to the automatic lacing system 24 based on one or more inputs from a user. The shoe assembly 20 may include additional components not specifically described herein.

As discussed in more detail below, shoe assembly 20 is configured to allow a user to tighten or loosen the laces of shoe 22 by sliding, tapping, pressing, or applying pressure to control or slide panel 32 of automatic lacing system 24. As non-limiting examples, the user may slide down panel 32 of automatic lacing system 24 to close or tighten the lace of automatic lacing system 24, slide up to open or loosen the lace, tap the upper end of panel 32 to more precisely loosen the lace, or tap the lower end of panel 32 to more precisely tighten the lace. These and other features will be described in more detail below.

Referring to FIG. 2, the shoe 22 is shown in greater detail. The shoe 22 includes a first or left shoe 40 and a second or right shoe 42, the left and

right shoes

40 and 42 may be similar in all material respects-except that the left and

right shoes

40 and 42 are sized and shaped to receive the user's left and right feet, respectively. For ease of disclosure, aspects of the present disclosure will be described with reference to a single shoe or article of footwear 44. In some figures, article of footwear 44 is depicted as a right shoe, and in some figures, article of footwear is depicted as a left shoe. The following disclosure with reference to article of footwear 44 applies to left shoe 40 and right shoe 42, and in some embodiments, differences may exist between left shoe 40 and right shoe 42 in addition to left/right configurations. For example, in some embodiments, left shoe 40 may include automatic lacing system 24 and right shoe 42 may not include automatic lacing system 24, or vice versa. Further, in some embodiments, left shoe 40 may include one or more additional elements not included with right shoe 42, and vice versa. As described below, the article of footwear 44 need not include an automatic lacing system 24, but may be manually laced in accordance with the lacing systems disclosed herein.

Fig. 3-6B depict an exemplary embodiment of an article of footwear 44 that includes an upper 50 and a sole structure 52. As will be discussed further herein, upper 50 is joined to sole structure 52 and together define an interior void 54 into which a user's foot may be inserted (see fig. 4 and 5). For reference, article of footwear 44 defines a forefoot region 56, a midfoot region 58, and a heel region 60 (see fig. 6A and 6B). Forefoot region 56 generally corresponds with portions of article of footwear 44 that surround the foot, including the toes, the ball of the foot, and the joints connecting the metatarsals with the toes or phalanges. Midfoot region 58 is adjacent and contiguous with forefoot region 56 and generally corresponds with the portion of article of footwear 44 that circumscribes the arch and bridge of the foot. Heel region 60 is proximate and adjacent to midfoot region 58 and generally corresponds with portions of article of footwear 44 that enclose a rear portion 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, such as textiles, polymer foam, polymer sheets, leather, and/or synthetic leather, that are joined by bonding or stitching at seams. In some embodiments, upper 50 of article of footwear 44 is formed from a knitted structure or knitted component. In various embodiments, the knitted component may incorporate various types of yarns that may provide different properties to the upper. For example, one area of upper 50 may be formed from a first type of yarn that imparts a first set of properties, and another area of upper 50 may be formed from a second type of yarn that imparts a second set of properties. With this configuration, the properties of upper 50 may vary throughout upper 50 by selecting specific yarns for different areas of upper 50. In a preferred embodiment, referring to FIG. 8, the article of footwear 44 includes a first or mesh layer 62 and a second or base layer 64. Base layer 64 may include multiple layers, such as an outer surface 66, on which a plurality of eyelets 68 may be provided on outer surface 66, and an inner surface 70 that engages the foot when the user wears article of footwear 44. The mesh layer 62 and base layer 64 may be attached at one or more locations along the article of footwear 44.

With respect to the materials comprising upper 50, a particular type of yarn will impart particular characteristics to areas of the knitted component, which may depend at least in part on the materials of the various filaments and fibers that form the yarn. For example, cotton can provide a soft effect, biodegradability, or natural aesthetics to the knitted material. The elastic fibers and stretched polyester can each provide a knitted component having the desired elasticity and recovery. Rayon may provide a high gloss and moisture absorbing material, wool may provide a material with enhanced moisture absorption, nylon may be a durable material that is abrasion resistant, and polyester may provide a durable material that is hydrophobic.

Other aspects of the knitted component may also be varied to affect the characteristics of the knitted component and provide desired attributes. For example, the yarns forming the knitted component may comprise monofilament or multifilament yarns, or the yarns may comprise filaments each formed from two or more different materials. In addition, the knitted component may be formed using a particular knitting process to impart particular characteristics to regions of the knitted component. Accordingly, the materials forming the yarns and other aspects of the yarns may be selected to impart various properties to specific areas of upper 50.

In some embodiments, the elasticity of the knitted structure may be measured by: after the knitted structure has a force applied to the knitted structure in the cross direction based on comparing the width or length of the knitted structure in the first non-stretched state to the width or length of the knitted structure in the second stretched state. In further embodiments, upper 50 may also include additional structural elements. For example, in some embodiments, a heel plate or cover (not shown) may be provided over the heel region 60 to provide additional support to the user's heel. In some cases, other elements, such as plastic materials, logos, trademarks, etc., may also be applied and secured to the outer surface using glue or a thermoforming process. In some embodiments, properties associated with upper 50, such as stitch types, yarn types, or properties associated with different stitch types or yarn types, such as elasticity, aesthetic appearance, thickness, breathability, or abrasion resistance, may vary.

Referring to fig. 4 and 5, the article of footwear 44 also defines a lateral side 80 and a medial side 82, with the lateral side 80 being shown in fig. 4 and the medial side 82 being shown in fig. 5. When the user wears the footwear, lateral side 80 corresponds with an outward-facing portion of article of footwear 44, and medial side 82 corresponds with an inward-facing portion of article of footwear 44. As such, left shoe 40 and right shoe 42 have opposing lateral side 80 and medial side 82 such that medial side 82 is closest to each other when the user wears footwear 22, while lateral side 80 is defined as the side that is furthest from each other when wearing footwear 22. As will be discussed in more detail below, medial side 82 and lateral side 80 abut one another at opposite distal ends of article of footwear 44.

Referring to fig. 6A and 6B, medial side 82 and lateral side 80 abut one another along a longitudinal central plane or axis 84 of article of footwear 44. As will be discussed further herein, a longitudinal central plane or axis 84 may define a central medial axis between medial side 82 and lateral side 80 of article of footwear 44. In other words, longitudinal plane or axis 84 may extend between a distal end 86 of a rear portion of article of footwear 44 and a distal end 88 of a forward portion of article of footwear 44, and may continuously define a central portion of insole 90, sole structure 52, and/or upper 50 of article of footwear 44, i.e., longitudinal plane or axis 84 is a straight axis that passes through distal end 86 of a rear portion of heel region 60, extending to distal end 88 of a forward portion of forefoot region 56.

Unless otherwise noted, and with reference to fig. 6A and 6B, article of footwear 44 may be defined by forefoot region 56, midfoot region 58, and heel region 60. Forefoot region 56 may generally correspond with portions of article of footwear 44 surrounding foot 92, with foot 92 including toes or phalanges 94, ball 96, and one or more joints 98, with one or more joints 98 connecting metatarsals 100 with toes or phalanges 94 of foot 92. Midfoot region 58 is proximate to and abuts forefoot region 56, with midfoot region 58 generally corresponding with portions of article of footwear 44 that wrap around the arch of foot 92 and along the bridge of foot 92. Heel region 60 is proximate midfoot region 58 and abuts midfoot region 58, heel region 60 generally corresponding with portions of article of footwear 44 that surround the rear of foot 92, including the heel or calcaneus 104, the ankle (not shown), and/or the achilles tendon (not shown).

Still referring to fig. 6A and 6B, forefoot region 56, midfoot region 58, heel region 60, medial side 82, and lateral side 80 are intended to define boundaries or regions of article of footwear 44. To this end, forefoot region 56, midfoot region 58, heel region 60, medial side 82, and lateral side 80 generally characterize portions of article of footwear 44. Certain aspects of the present disclosure may relate to portions or elements that are coextensive with one or more of forefoot region 56, midfoot region 58, heel region 60, medial side 82, and/or lateral side 80. In addition, both upper 50 and sole structure 52 may be characterized as having portions in forefoot region 56, midfoot region 58, heel region 60, and/or along medial side 82 and/or lateral side 80. Accordingly, upper 50 and sole structure 52 and/or individual portions of upper 50 and sole structure 52 may include portions disposed within forefoot region 56, midfoot region 58, heel region 60, and/or along medial side 82 and/or lateral side 80.

Still referring to fig. 6A and 6B, fig. 6A and 6B illustrate forefoot region 56, midfoot region 58, heel region 60, medial side 82, and lateral side 80 in detail. Forefoot region 56 extends from toe end 110 to widest portion 112 of article of footwear 44. The widest portion 112 is defined or measured along a first line 114, the first line 114 being perpendicular to the longitudinal axis 84, the longitudinal axis 84 extending from a distal portion of the toe end 110 to a distal portion of the heel end 116 opposite the toe end 110. Midfoot region 58 extends from widest portion 112 to thinnest portion 118 of article of footwear 44. A thinnest portion 118 of the article of footwear 44 is defined as the thinnest portion of the article of footwear 44, with the thinnest portion 118 being measured from a second line 120 passing through and perpendicular to the longitudinal axis 84. Heel region 60 extends from thinnest portion 118 to heel end 116 of article of footwear 44.

It should be understood that many modifications will be apparent to those skilled in the art in view of the foregoing description, and that individual components thereof may be incorporated into many articles of footwear. Accordingly, aspects of article of footwear 44 and its components may be described with reference to general areas or portions of article of footwear 44, with the understanding that the boundaries of forefoot region 56, midfoot region 58, heel region 60, medial side 82, and/or lateral side 80 as described herein may vary between articles of footwear.

However, aspects of article of footwear 44 and its individual components may also be described with reference to specific areas or portions of article of footwear 44, and the scope of the claims appended hereto may include limitations associated with such boundaries of forefoot region 56, midfoot region 58, heel region 60, medial side 82, and/or lateral side 80 as discussed herein.

Still referring to fig. 6A and 6B, the medial side 82 begins at the distal toe end 88 and curves outward toward the midfoot region 58 along the medial side of the forefoot region 56 along the article of footwear 44 d. The inner side 82 reaches the first line 114 at which point the inner side 82 curves inwardly toward the central longitudinal axis 84. Medial side 82 extends from first line 114, i.e., widest portion 112, toward second line 120, i.e., thinnest portion 118, at which point medial side 82 enters midfoot region 58, i.e., while passing through first line 114. Upon reaching second line 120, medial side 82 curves outward, away from longitudinal central axis 84, at which point medial side 82 extends into heel region 60 — i.e., while traversing second line 120. Medial side 82 then curves outward, then curves inward toward heel end 86, and terminates at the point where medial side 82 meets longitudinal central axis 84.

Still referring to fig. 6A and 6B, lateral side 80 also begins at a distal toe end 88 and curves outward toward midfoot region 58 along a lateral side of forefoot region 56 of article of footwear 44. The outer side 80 reaches a first line 114 at which point the outer side 80 curves inward toward the longitudinal central axis 84. Lateral side 80 extends from a first line 114, i.e., widest portion 112, toward a second line 120, i.e., thinnest portion 118, at which point lateral side 80 enters midfoot region 58, i.e., while traversing first line 114. Upon reaching second line 120, lateral side 80 curves outward away from central longitudinal axis 84, at which point lateral side 80 extends into heel region 60, i.e., while traversing second line 120. Lateral side 80 then curves outward, then curves inward toward heel end 86, and terminates at the point where lateral side 80 meets longitudinal central axis 84.

Referring back to fig. 4 and 5, sole structure 52 is connected or secured to upper 50, and sole structure 52 extends between the user's foot and the ground when article of footwear 44 is worn by the user. Sole structure 52 may also include one or more components that may include an outsole, a midsole, a heel, an upper, 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 traction for the user, a midsole that provides a cushioning system, and an insole that provides support for the arch of the user.

Referring to fig. 4-6A, sole structure 52 of the present embodiment may be characterized by an outsole or outsole region 130, a midsole region 132, and an insole or insole region 134 (see fig. 6A). Outsole region 130, midsole region 132, insole region 134, and/or any component thereof, may include portions within forefoot region 56, midfoot region 58, and/or heel region 60. In addition, outsole region 130, midsole region 132, and insole region 134, and/or any components thereof, may include portions on lateral side 80 and/or medial side 82.

In other instances, outsole region 130 may be defined as a portion of sole structure 52 that at least partially contacts an exterior surface, such as the ground, when article of footwear 44 is worn. The insole region 134 may be defined as a portion of the sole structure 52 that at least partially contacts a user's foot when the article of footwear is worn. Finally, midsole region 132 may be defined as at least a portion of sole structure 52 that extends between and connects outsole region 130 and insole region 134.

As shown in fig. 4 and 5, upper 50 extends upward from sole structure 52 and defines an interior void 54 that receives and secures a foot of a user. Upper 50 may be defined by a foot region 136 and an ankle region 138. Generally, foot region 136 extends upward from sole structure 52 and through forefoot region 56, midfoot region 58, and heel region 60. Ankle region 138 is primarily located in heel region 60; however, in some embodiments, ankle region 138 may extend partially into midfoot region 58.

Referring again to fig. 4 and 5, fig. 4 and 5 show article of footwear 44 without outer mesh layer 62, with the lacing portion of automatic lacing system 24 shown in greater detail. Automatic lacing system 24 includes a housing 140 defining a panel 32, and a lace including a lateral or first lace 142 and a medial or second lace 144. The automatic lacing system 24 also includes a number of electronic components, as will be discussed below. The first strap 142 extends through a plurality of lateral eyelets 146 and the second strap 144 extends through a plurality of medial eyelets 148. Lateral eyelet 146 includes a first lateral eyelet 150, a second lateral eyelet 152, a third lateral eyelet 154, a fourth lateral eyelet 156, and a fifth lateral eyelet 158. Medial eyelet 148 includes a first medial eyelet 160, a second medial eyelet 162, a third medial eyelet 164, a fourth medial eyelet 166, and a fifth medial eyelet 168. Both first lace 142 and second lace 144 also extend through a first channel or slit 170 and a second channel or slit 172 disposed within a strap 174, which strap 174 extends across midfoot region 58, adjacent a base of a tongue 176. Lateral eyelet 146 is disposed throughout forefoot region 56, midfoot region 58, and heel region 60, and medial eyelet 148 is disposed throughout forefoot region 56, midfoot region 58, and heel region 60.

In addition, first lace 142 and second lace 144 each include a portion disposed within housing 140 that allows automatic lacing system 24 to pull in

laces

142, 144 or to pay out

laces

142, 144 depending on the particular input or desired operation by the user. In a preferred embodiment, first lace 142 and second lace 144 are closed loops and each include a portion disposed within housing 140, a portion extending through strap 174, and a portion extending through

eyelets

146, 148. In some embodiments, first lace 142 and/or second lace 144 may not include a closed loop, but may have ends that are fixedly attached to portions of article of footwear 44.

Referring to FIG. 4, first lace 142 extends from first lateral aperture 180, down shell 140 and slightly toward forefoot region 56 to first lateral eyelet 150. First lace 142 may be slightly curved or angled as it passes through first lateral eyelet 150, however, first lace 142 remains substantially linear as it passes through first lateral eyelet 150. First lace 142 then extends to second lateral eyelet 152, through which second lateral eyelet 152 first lace 142 passes as it extends toward third lateral eyelet 154. First lace 142 forms an angle of approximately 120 degrees when threaded through the second lateral eyelet. After passing through second lateral eyelet 152, first lace 142 extends toward forefoot region 56 and through third lateral eyelet 154. First lace 142 forms an angle of approximately 80 degrees when passing through third lateral eyelet 154. After passing through third lateral eyelet 154, first lace 142 extends upward and rearward toward strap 174. First lace 142 then passes through first channel 170 in strap 174 toward the heel region and extends downward toward fourth lateral eyelet 156. When first lace 142 extends toward fourth lateral eyelet 156, first lace 142 spans the portion of first lace 142 that extends between first lateral eyelet 150 and second lateral eyelet 152. In some embodiments, first lace 142 passes under a portion of first lace 142 that extends between first lateral eyelet 150 and second lateral eyelet 152. First lace 142 forms an angle of approximately 155 degrees when passing through fourth lateral eyelet 156.

Still referring to fig. 4, once fourth lateral eyelet 156 is reached, first lace 142 is slightly canted and extends to fifth lateral eyelet 158. First lace 142 forms an angle of approximately 50 degrees when passing through fifth lateral eyelet 158. At fifth lateral eyelet 158, first lace 142 is sharply folded back toward midfoot region 58 and extends upward to second lateral aperture 182 of shell 140. First lace 142 then passes through second exterior aperture 182 and into housing 140, as discussed in more detail below. Alternative configurations of lacing structures as described above are contemplated and may include more or fewer eyelets and/or intersections of first lace 142 with first lace 142 itself. However, as discussed above, in a preferred embodiment, first lace 142 spans first lace 142 itself once. In some embodiments, first lace 142 may cross over first lace 142 itself two, three, four, five, six, or seven times. However, in a preferred embodiment, the particular orientation of housing 140, first eyelet 146, and strap 174 allows article of footwear 44 to be adequately and securely tightened around a user's foot, and the force exerted by first lace 142 and second lace 144 is distributed over the user's foot in an efficient and retentive manner so as to exert a reduced force along the user's foot when article of footwear 44 is worn. In this sense, the preferred orientation of first lace 142 is to extend through two of first eyelets 146 and through the remaining eyelets, as described above, downward from housing 140 toward sole structure 52.

Referring to FIG. 5, second strap 144 extends from first medial hole 184 to first medial eyelet 160, down shell 140 and slightly toward forefoot region 56. Second lace 144 may be slightly curved or angled as it passes through first medial eyelet 160, however, second lace 144 remains substantially linear as it passes through first medial eyelet 160. The second lace 144 then extends to a second medial eyelet 162, through which the second lace 144 passes as it extends toward a third medial eyelet 164. The second lace 144 forms an angle of approximately 120 degrees when passing through the second medial eyelet. After passing through second medial eyelet 162, second lace 144 extends toward forefoot region 56 and through third medial eyelet 164. The second lace 144 forms an angle of approximately 80 degrees when passing through the third medial eyelet 164. After passing through third medial eyelet 164, second lace 144 extends upward and rearward toward lace 174. Second lace 144 then passes through second channel 172 in strap 174, toward heel region 60, and then extends downward toward fourth medial eyelet 166. When the second lace 144 is threaded through the portion of the second lace 144 that extends between the first medial eyelet 160 and the second medial eyelet 162, the second lace 144 extends toward the fourth medial eyelet 166. In some embodiments, second lace 144 passes under a portion of second lace 144 that extends between first medial eyelet 160 and second medial eyelet 162. The second lace 144 forms an angle of approximately 155 degrees when passing through the fourth medial eyelet 166.

Still referring to fig. 5, once fourth medial eyelet 166 is reached, second lace 144 is angled slightly and extends to fifth medial eyelet 168. The second strap 144 forms an angle of approximately 50 degrees when passing through the fifth medial eyelet 168. At fifth medial eyelet 168, second strap 144 is sharply folded back toward midfoot region 58 and extends upward to a second medial hole 186 of shell 140. The second lace 144 then passes through the second medial hole 186 and into the housing 140, as discussed in more detail below. Alternative configurations of lacing structures as described above are contemplated and may include more or fewer eyelets and or crossings of second lace 144.

As described above, the second lace 144 crosses itself once. In some embodiments, second lace 144 may itself be crossed two, three, four, five, six, or seven times. However, in a preferred embodiment, the particular orientation of housing 140, second lace 148, and straps 174 allows article of footwear 44 to be properly and securely tightened around the user's foot, and the force exerted by first lace 142 and second lace 144 is distributed over the user's foot in an efficient and retentive manner so as to exert a reduced force along the user's foot when article of footwear 44 is worn. In this sense, the preferred orientation of second strap 144 is to extend downward from housing 140, through both second straps 148 and through the remaining straps toward sole structure 52, as described above.

Lacing system 24 as described above may allow a user to modify dimensions of upper 50, such as tightening or loosening portions of upper 50 around the foot, as desired by the user. As will also be discussed in further detail herein, the lacing system 24 may allow a user to modify the tightness depending on the needs of the user. In some embodiments, when a user inputs a command, first lace 142 and second lace 144 are tightened or loosened by the same amount. In some embodiments, only one of first lace 142 or second lace 144 is tightened or loosened when the user inputs a command. In some embodiments, first lace 142 is tightened or loosened to a first tightness level and second lace 144 is tightened or loosened to a second tightness level that is different than the first tightness level. In this manner, first lace 142 and second lace 144 may be tightened to the same level of tightness or may be tightened to different levels.

Referring to fig. 6A and 6B, upper 50 extends along a lateral side 80 and a medial side 82 and across forefoot region 56, midfoot region 58, and heel region 60 to receive and enclose a user's foot. When fully assembled, upper 50 also includes an interior surface 190 and an exterior surface 192. Interior surface 190 faces inwardly and generally defines interior void 54, and exterior surface 192 of upper 50 faces outwardly and generally defines an outer periphery or boundary of upper 50. The inner surface 190 and the outer surface 192 may comprise portions of the

layers

62, 64 disclosed above. Upper 50 also includes an opening 194, opening 194 being located at least partially in heel region 60 of article of footwear 44, opening 194 providing access to interior void 54 and through which the foot may be inserted and removed. In some embodiments, upper 50 may also include an instep region 196, with instep region 196 extending from opening 194 in heel region 60 over an instep region corresponding with the foot to an area adjacent forefoot region 56. Instep area 196 may include an area of similar disposition to tongue 176 of the present embodiment. In some embodiments, upper 50 does not include tongue 176, i.e., upper 50 is tongue-less, and housing 140 is disposed along a portion of upper 50, as described above.

Referring to fig. 6A, the housing 140 or components of the housing 140 may be formed by Additive Manufacturing Techniques, such as by 3D printing. To this end, various 3D printing techniques may be implemented to form the housing 140, such as high volume photopolymerization, material jetting, adhesive jetting, powder bed fusion, material extrusion, directed energy deposition, and/or sheet lamination. In some embodiments, the shell 140 or components of the shell 140 may be 3D printed directly on the instep region 196, or along another region of the foot, such as the forefoot region 56, midfoot region 58, or heel region 60. In some embodiments, the housing 140 or components of the housing 140 may be 3D printed and then separately coupled with a portion of the shoe 44.

Referring to fig. 7, the housing 140 of the automatic lacing system 24 is shown in greater detail. The housing 140 is centrally disposed along a tongue 176, the tongue 176 being located between the lateral side 80 of the upper 50 and the medial side 82 of the upper 50. Strap 174 is located at a base of tongue 176. strap 174 includes

channels

170, 172 through which first and

second laces

142, 144 may move when the lace is tightened or loosened. The panel 32 along the housing 140 is best shown in fig. 7. First and second

lateral apertures

180, 182 and first and second

medial apertures

184, 186 are also shown through which first lace 142 and second lace 144 extend. Design elements 200 are also provided along the tongue 176. in some embodiments, the tongue 176 may include LEDs or sensors provided along the tongue 176 that may receive or provide feedback from the user. Tongue 176 of article of footwear 44 may be attached to upper 50 at a plurality of attachment points or along the sides and base of upper 50. The tongue 176 may also include additional aspects not specifically set forth herein.

Referring now to FIG. 8, a partial exploded view of the layering of an article of footwear 44 is shown. As provided in the exploded view, first or mesh layer 62 and second or base layer 64 are shown separate from article of footwear 44. The mesh layer 62 is shown to include a mesh or net structure having a plurality of apertures 202 disposed along the net structure. The base layer 64 is a substantially uniform layer without any holes or voids along the base layer 64. In addition, base layer 64 includes a plurality of eyelets 68. Portions of base layer 64 and portions of mesh layer 62 combine to form exterior surface 192 of upper 50. When the article of footwear 44 is fully assembled, the base layer 64 is also disposed below the mesh layer 62. There may be additional layers disposed intermediate mesh layer 62 and base layer 64, for example, in some embodiments, one or more additional layers are disposed between base layer 64 and mesh layer 62. In some embodiments, additional layers are disposed above or below mesh layer 62 or base layer 64, respectively.

First layer 62 and second layer 64 may include varying properties, such as stitch types, yarn types, or properties associated with different stitch types or yarn types, such as elasticity, aesthetic appearance, thickness, breathability, or abrasion resistance, may vary between first layer 62 and second layer 64, and/or may vary between other portions of upper 50. For example, upper 50 and the individual components of upper 50, such as mesh layer 62 and base layer 64, may be formed individually using various elements, textiles, polymers (including foamed polymers and polymer sheets), leather, synthetic leather, and the like. In addition, upper 50 and the individual components of upper 50 may be joined together by bonding, stitching, or by seams to form upper 50.

Referring to fig. 9A-15, the lacing system 24 will now be described in more detail. Referring to fig. 9A and 9B, the dashed lines of some of the internal components of automatic lacing system 24 illustrate a gear 210, a worm gear 212, a gear train 214 including additional gears, and an electric motor 216. A spool (not shown) is formed by the underside of gear 210 and is operable to wind first lace 142 and second lace 144. Portions of the housing 140 are removed for clarity. Specific gear configurations will be discussed below, but the motor 216 is operable to rotate the worm gear 212 via the gear train 214. Worm gear 212 is configured to drive gear 210, which allows first lace 142 and second lace 144 to rotate about gear axis 218. As the gear 210 rotates about an axis 218 that coincides with the axis of the spool and pulls the first lace 142 and the second lace 144, the

laces

142, 144 are tightened or loosened depending on the direction of rotation of the gear 210 (and by extension, the worm gear 212, the gear of the gear train 214, and the motor 216). As described below, the motor 216 may be a dc brushless motor.

Referring specifically to fig. 9A, the gear 210 includes a first aperture 220 and a second aperture 222 on an outer or right side 224 of the gear 210, and a third aperture 226 and a fourth aperture 228 on an inner or left side 230 of the gear 210. The first and

second apertures

220, 222 are disposed adjacent one another and the third and

fourth apertures

226, 228 are disposed adjacent one another. In a preferred embodiment, first lace 142 enters housing 140, passes upward through first aperture 220, and returns downward through second aperture 222. In a preferred embodiment, second lace 144 enters housing 140, passes upward through third aperture 226, and passes back downward through fourth aperture 228. This positioning allows first lace 142 and second lace 144 to be pulled inward about gear shaft 218 in the direction of arrows a or B, depending on whether automatic lacing system 24 is being used to tighten or loosen

laces

142 and 144. As is apparent from the orientation of first lace 142 and second lace 144 along gear 210, first lace 142 and second lace 144 are simultaneously tightened or loosened to the same degree in this orientation.

In a preferred embodiment, from an initial or released configuration (shown in fig. 9A), rotation of gear 210 by about 90 degrees results in a first level of tightness, rotation of gear 210 by about 180 degrees results in a second level of tightness, rotation of gear by about 270 degrees results in a third level of tightness, and so on. In some embodiments, rotation of the gear 210 in increments of about 60 degrees results in a first level of tightness, a second level of tightness, a third level of tightness, and so on. In some embodiments, rotation of the gear 210 in increments of about 45 degrees results in a first level of tightness, a second level of tightness, a third level of tightness, and so on. In some embodiments, rotation of the gear 210 in increments of about 30 degrees results in a first level of tightness, a second level of tightness, a third level of tightness, and so on. In some embodiments, rotation of the gear 210 in increments of about 15 degrees results in a first level of tightness, a second level of tightness, a third level of tightness, and so on.

Still referring to fig. 9A, the worm gear 212 defines a worm shaft 238, a first gear 240 is disposed along the worm shaft 238, the first gear 240 being one of the gears in the gear train 214. Referring to fig. 9B, the motor housing 242 is shown with the housing 140 removed (see fig. 11 and 12), while the gear base 244 of the housing 140 is shown with the gear 210 coupled to the gear base 244. In fig. 9B, the first gear 240 is visible along with the gear 210 and the worm gear 212, however, the remaining gears of the gear train 214 are hidden by the gear train housing 246. A gear train housing 246 is provided to maintain the gear train 214 in a compact and protected configuration. As provided in fig. 9B and 10B, the gear train 214 and gear train housing 246 are disposed along lateral sides of the bottom of the housing 140. Further, the motor 216 is disposed at the heel end of the bottom of the housing 140, and the gear 210 is disposed at the mid-foot end of the bottom of the housing 140.

Referring now to fig. 10A and 10B, the dashed lines of some of the internal components of automatic lacing system 24 illustrate gear 210, worm gear 212, gear train 214, and motor 216. With particular reference to fig. 10A, the gear 210 includes a first aperture 220 and a second aperture 222 on a right side 224 of the gear 210, and a third aperture 226 and a fourth aperture 228 on a left side 230 of the gear 210. The first and

second apertures

220, 222 are disposed adjacent one another and the third and

fourth apertures

226, 228 are disposed adjacent one another. In an alternative embodiment shown in fig. 10A and 10B, first lace 142 enters housing 140, passes upward through first aperture 220, and passes back downward through third aperture 226. In the same embodiment, second lace 144 is threaded into housing 140, up through second aperture 222, and down back through fourth aperture 228. This positioning allows first lace 142 and second lace 144 to be pulled inward about gear shaft 218 in the direction of arrows a or B, depending on whether automatic lacing system 24 is being used to tighten or loosen

laces

Fig. 11-15 illustrate the components of automatic lacing system 24 in an exploded configuration. Referring specifically to fig. 11, an exploded perspective view of some of the components of automatic lacing system 24 is shown. These components include the top cover 250, gear base 244, motor housing 242, gear train housing 246, gear 210, worm gear 212, and gear train 214. The worm gear 212 is disposed around the first shaft 252, and the first gear 240 is disposed at an end of the first shaft 252. The worm gear 212, the first shaft 252, and the first gear 240 comprise a first gear assembly 254. The second gear assembly 256 includes a second gear 258 and a third gear 260 (see fig. 13) disposed along a second axis 262. The second gear 258 and the third gear 260 are fixedly coupled to each other, and thus, when the second gear 258 rotates, the third gear 260 also rotates. A third gear assembly 264 is also provided, the third gear assembly 264 including a fourth gear 266 and a fifth gear 268 (see fig. 13). The fourth gear 266 and the fifth gear 268 are fixedly coupled to each other and disposed along a third shaft 270. Also shown is a motor gear 272 extending from the motor 216, the motor gear 272 being disposed along a motor shaft 274 (see fig. 15).

The first gear 240, the second gear 258, the third gear 260, the fourth gear 266, and the fifth gear 268 may be spur gears or cylindrical gears. Spur or spur gears include cylinders or disks with radially projecting teeth. Although the teeth are not straight-sided, the edge of each tooth is straight and aligned parallel to the axis of rotation. When two of the gears, such as the first gear 240 and the third gear 260, mesh, a mechanical advantage results if one gear is larger than the other (the first gear 240 has a larger diameter than the third gear 260), where the rotational speed and torque of the two gears differ proportionally to their diameters. Since the larger gear rotates slower, the torque of the larger gear is proportionally greater, and in this example, the torque of third gear 260 is proportionally greater than the torque of first gear 240.

Still referring to fig. 11-15, the first gear assembly 254 includes a worm gear 212, the worm gear 212 in communication with the gear 210. The worm gear is a helical gear but the worm gear helix angle is typically slightly larger (approaching 90 degrees) and the worm gear body is typically quite long in the axial direction. As will be appreciated by those of ordinary skill in the art, the use of worm gear 212 enables a high torque, low speed gear ratio to be achieved between worm gear 212 and gear 210 in a simple and compact manner. In this embodiment, worm gear 212 may drive gear 210 at all times, but not necessarily. The combination of worm gear 212 and gear 210 forms a self-locking system, thus, the advantage is achieved that worm gear 212 can easily be used to hold this position when a certain level of tightness is required. The worm gear 212 may be Right-Handed or Left-Handed ("Right or Left-Handed"). For purposes of this disclosure, worm gear assembly 276 includes gear 210, worm gear 212, first shaft 252, and first gear 240. The worm gear 212, the first shaft 252, and the first gear 240 may comprise a single material, or may comprise different materials.

The worm gear assembly 276 is in communication with the second gear assembly 256, the second gear assembly 256 is in communication with the third gear assembly 264, and the third gear assembly 264 is in communication with the motor gear 272. Thus, when motor shaft 274 is rotated by motor 216, motor gear 272 rotates in either a clockwise or counterclockwise direction depending on whether gear 210 needs to be rotated clockwise or counterclockwise, i.e., tightening or loosening of first lace 142 and second lace 144. The motor gear 272 communicates with a fifth gear 268, and rotation of the fifth gear 268 causes rotation of the third shaft 270 and the fourth gear 266. The fourth gear 266 is in communication with the second gear 258, the second gear 258 being fixedly coupled with the third gear 260. As described above, the second gear 258, the third gear 260, and the second shaft 262 comprise the second gear assembly 256.

Still referring to fig. 11-15, when the third gear assembly 264 is rotated by the motor gear 272, the second gear assembly 256 is thereby rotated. Third gear 260 of second gear assembly 256 is in communication with first gear 240 such that rotation of third gear 260 rotates first gear 240. When the first gear 240 is rotated by the second gear assembly 256, the first gear 240 rotates the first shaft 252, and the first shaft 252 is fixedly coupled with the worm gear 212. So that the worm wheel 212 is rotated when the first gear 240 is rotated. Since gear 210 is in communication with worm gear 212, when first gear assembly 254 is rotated, gear 210 is also rotated. As gear 210 rotates, first lace 142 and second lace 144 are pulled into the housing about gear axis 218 or spool. As described above, the first gear assembly 254 includes the first gear 240, the first shaft 252, and the worm gear 212. The worm gear assembly 276 includes a first gear assembly 254 and a gear 210. To this end, when the motor gear 272 rotates, the third gear assembly 264 rotates the second gear assembly 256, and the second gear assembly 256 rotates the worm gear assembly 276.

Referring now to fig. 11 and 12, the motor housing 242, base 244, gear box 140, and top cover 250 of the housing 140 are shown in detail. The motor housing 242 includes lace apertures 280 located on the left and right sides (or inner and outer sides) of the motor housing 242 and gear train apertures 282 along the right side (or outer side) of the motor housing 242. Lace apertures 280 allow first lace 142 and second lace 144 to pass unobstructed into motor housing 242. The motor housing 242 also includes an outer platform 284 that surrounds a motor compartment 286. The motor compartment 286 houses all of the

gear assemblies

256, 264, 276 and the motor 216. The gear box 140 includes a plurality of shaft retaining holes 288 (see fig. 15), the shaft retaining holes 288 retaining the

Cylindrical reel 292 may be sized and shaped to retain first lace 142 and second lace 144 as the laces are wound around spool 290 during operation of lacing system 24. The spool 292 may have a varying diameter, but in a preferred embodiment, the diameter of the spool 292 is less than the diameter of the gear 210. In some embodiments, spool 290 need not include lower flange 294, and thus, the spool may simply comprise a cylindrical structure with a lace wound around the spool. As gear 210 rotates, first lace 142 and second lace 144 are wound on reel 292 and thereby pulled into housing 140. Spool 290 may be rotated clockwise or counterclockwise depending on whether the

laces

142, 144 are tightened or loosened. Spool shaft 296 may be disposed on gear base 244 or in rotatable communication with gear base 244.

Although the top cover 250 may be any color, including black, in a preferred embodiment, light may be seen through the top cover 250 when one or more light sources are activated within the housing 140. Specific activation of the light sources will be discussed with reference to fig. 18A-18M.

A sensor system 320 is shown in fig. 16, the sensor system 320 configured to be disposed between the top cover 250 and the motor housing 242 of the housing 140. The sensor system 320 includes a flexible circuit 322, the flexible circuit 322 including a plurality of slide sensors 324 disposed along the flexible circuit 322. The slide sensor 324 is in the shape of a repeating chevron or letter "M," however, the slide sensor 324 may include alternative shapes such as oval, square, rectangular, circular, triangular, or other polygonal shapes. The slide sensor 324 is responsive to tactile interaction of a user with the faceplate 32 of the housing 140. The sensor system 320 includes multiple layers that may include varying circuitry, sensors, LEDs, and the like. The sensor system 320 also includes a first controller or microcontroller 326, the first controller or microcontroller 326 being shown disposed along an inner or left side 328 of the sensor system 320. A plurality of resistors 330 are disposed along the flexible circuit 322. Further, a plurality of light emitting diodes or LEDs 332 are disposed along the perimeter of the flexible circuit 322. A plurality of LEDs 332 are disposed along the flexible circuit 322 such that when fully assembled, the LEDs 332 are aligned with the exterior side 312, the front side 314, and the interior side 316 of the top cover 250.

As described above, the flexible circuit 322 may be disposed between the top cover 250 and the motor housing 242. The flexible circuit 322 includes a plurality of slide sensors 324, and in some embodiments, the slide sensors 324 may also be caused to blink or illuminate in response to signals sent by one or more controllers including a microcontroller 326. In some embodiments, additional LEDs are provided along the panel 32 or along another portion of the housing 140. As described above, the flexible circuit 322 may be provided in an inverted configuration, depending on the differences between the left shoe 40 and the right shoe 42. When the automatic lacing system 24 is assembled, the slide sensor 324 of the flexible circuit 322 is disposed below the panel 32 of the top cover 250 of the housing 140. As a result, a plurality of LEDs 332 are disposed along and adjacent to the sides of the top cover 250. The top cover 250 may have a transparent or translucent portion to allow light emitted from the LED332 to pass through.

Still referring to fig. 16, in this embodiment, the flexible circuit 322 includes 16 LEDs 332, and the LEDs 332 are positioned around the perimeter of the motor compartment 286 and under the top cover 250 when the lacing system 24 is assembled. LED332 provides light-based feedback to the user. In particular, the LEDs 332 provide visual cues, such as a low-power warning, indicative of the tightness level of the

laces

142, 144 and/or the energy level of the battery 340 (see fig. 20, 22, and 24), as well as a visual cue indicative of when the battery 340 is charged. For example, none of LEDs 332 may be illuminated when

laces

142, 144 are in an open configuration, four of LEDs 332 are illuminated when automatic lacing system 24 is in a first state, nine of LEDs 332 are illuminated when automatic lacing system 24 is in a second state (tighter than the first state), and/or sixteen of LEDs 332 are illuminated when automatic lacing system 24 is in a third state (tighter than the first and second states). As described above, the LEDs 332 are located below the top cover 250 of the housing 140. The LEDs may also be arranged to illuminate various symbols along or inside the top cover 250, such as stars, battery charging information, etc., when the battery is in a low-battery mode, or to illuminate illuminated symbols when the battery is charging, for example.

Referring now to fig. 17A and 17B, side views of the shoe 44 are shown in a loosened configuration and a tightened configuration, respectively. With particular reference to fig. 17A, in the loosened configuration, first strap 142 and second strap 144 are not tightened, but are threaded through all of first eyelet 146 and second eyelet 148, respectively. In some embodiments, first lace 142 and second lace 144 have a slight amount of pretension to ensure that the instep of the foot is more comfortable if the shoe is in the untightened mode. To this end, the shoe 44 shown in FIG. 17A achieves a more comfortable instep position that the user may use in some circumstances when wearing the shoe 44. Referring back to fig. 9A, in the loosened configuration, first lace 142 and second lace 144 may be arranged as shown in this detailed view with gear 210 not rotating in order to tighten first lace 142 or second lace 144. Although gear 210 may be disposed in an alternative configuration in the released state, gear 210 is preferably disposed in the released configuration in a manner similar to that shown in fig. 9A. In a preferred embodiment, a line drawn between the first aperture 220 and the third aperture 226 of the gear 210 is parallel to the axis of the first shaft 252 in the released configuration.

Referring now to fig. 17B, when automatic lacing system 24 is commanded to tighten first lace 142 and second lace 144, tongue 176 and housing 140 are pulled downward in the direction of arrow C, thereby achieving a first tightened configuration. Any number of tightening configurations are possible depending on the level of tightness that can be achieved by user input or preset settings of the automatic lacing system 24. The first tightened configuration may have a first tightness level and the second tightened configuration may have a second tightness level greater than the first tightness level. Referring again to fig. 9A, a first level of tightness may be achieved when the gear 210 is rotated about 15 degrees, or about 30 degrees, or about 45 degrees, or about 60 degrees, or about 90 degrees. Each subsequent level of tightness may be achieved by rotating the gear 210 by another amount, which may be about 15 degrees, or about 30 degrees, or about 45 degrees, or about 60 degrees, or about 90 degrees.

Once shoes 44 have been in the first tightened configuration, shoes 44 may be returned to the loosened configuration by rotating gear 210 in the opposite direction, i.e., if gear 210 is tightened by rotating in the direction of arrow a (see fig. 9A), gear 210 is loosened by rotating in the direction of arrow B. To this end, the shoe 44 in the released configuration shown in fig. 17A may be adjusted to the tightened configuration shown in fig. 17B, and may then be returned to the initial released configuration shown in fig. 17A. The

laces

142, 144 of the shoe 44 may be tightened or loosened any number of times and in any increment. Certain tightening/loosening sequences are described in this application, however, the disclosure is not intended to be so limited.

Referring now to fig. 18A-18M, as previously described, a user may manipulate automatic lacing system 24 using two methods: (1) physical contact with the face plate 32 of the housing 140, i.e., user interaction with the slide sensor 324; and (2) using the wireless device 30. A first method of manipulation, physical adjustment, will be discussed with reference to fig. 18A-18M. To this end, automatic lacing system 24 may have a predetermined level of tightness, including an open configuration in which laces 142 and 144 are loosened to a predetermined degree of tightness, and a closed configuration in which laces 142 and 144 are tightened to a predetermined degree of tightness. In practice, the user can slide down on panel 32 to tighten

laces

142, 144 to a predetermined tightness of the closed configuration, or slide up on panel 32 to loosen

laces

142, 144 to a predetermined tightness of the open state. Further, the user may adjust the predetermined tightness of the laces in the open and closed states by tapping the upper end of panel 32 to decrease the tightness in the closed or open configurations, or by tapping the bottom end of panel 32 to increase the tightness in the closed or open configurations. Further, the user may reset the predetermined level by applying pressure to the panel 32 for a predetermined amount of time, such as 10 seconds, the user may "wake up" or activate the automatic lacing system 24 by tapping on the panel 32, or the user may connect/pair the wireless devices 30 by applying pressure to the top surface for a second predetermined amount of time, such as 1-2 seconds, as discussed in more detail below.

Fig. 18A-18M depict schematic diagrams of a slide command along the control/display panel 32 in various states and show various responses to one or more input commands. A plurality of LEDs 332 are shown illuminated in various configurations based on the status of the automatic lacing system 24. For example, when the article of footwear 44 is in the released configuration, none of the LEDs 332 are activated. When the article of footwear 44 is in the first slack level configuration, the LEDs 332 of the bottom row are illuminated. When the article of footwear 44 is in the second slack level configuration, the LEDs 332 of the bottom row and the LEDs 332 of the side columns are illuminated. In the figure, a first circle 342 indicates a touch point of the user along the panel 32, and an arrow 344 indicates a sliding direction to a second circle 346, the second circle 346 indicating another touch point along the panel 32.

Various swipe commands will now be described. Referring specifically to FIG. 18A, a first or close swipe command 350 is shown. To implement the close slide command 350, the user touches the panel 32 at the first circle 342 and slides down in the direction of arrow 344 toward the second circle 346. The close slip command 350 may fully tighten the shoe 22. Referring to FIG. 18B, a second or open slide command 352 is shown. To implement the open slide command 352, the user touches the panel 32 at the first circle 342 and slides in the direction of arrow 344 toward the second circle 346. The open slip command 352 may fully release the shoe 22. Referring to fig. 18C, an adjust/release command 354 is shown. To implement the adjust/release command 354, the user touches the panel 32 at the first circle 342. Adjustment/release command 354 incrementally releases the lace of automatic lacing system 24. Referring to FIG. 18D, adjust/tighten instructions 356 are shown. To implement adjust/tighten command 356, the user touches panel 32 at first circle 342. Adjustment/tightening command 356 incrementally tightens the lace of automatic lacing system 24.

Referring now to FIG. 18E, a reset command 358 is shown. To implement the reset command 358, the user touches or presses the panel 32 at the first circle 342 for 10 seconds. Reset command 358 may return automatic lacing system 24 to a factory setting or other type of zero setting. Referring to fig. 18F, a connect/pair command 360 is shown. To implement the connect/pair command 360, the user presses the panel 32 at the first circle 342 for one to two seconds. The connect/pair command 360 may be used to connect or pair the shoe 22 with the electronic device 30 via bluetooth. Referring to FIG. 18G, a wake command 362 is shown. To implement the wake-up command 362, the user touches the panel 32 at the first circle 342. The wake command 362 may turn on the automatic lacing system 24.

Referring now to fig. 18H-18K, various illumination configurations of the LED332 are shown, the illumination configurations representing an open configuration 364, a first closed configuration 366, a second closed configuration 368, and a third closed configuration 370, respectively. In the open configuration 364, no LEDs 332 are illuminated. In the first closed configuration 366, four LEDs 332 along the bottom row of LEDs 332 are illuminated. In the second closed configuration 368, four LEDs 332 along the bottom row of the panel 32 and six LEDs 332 along each side column are illuminated. In the third closed configuration 370, all of the LEDs 332 are illuminated. It will be appreciated that the open configuration 364 may indicate that the automatic lacing system 24 is in a fully open state, while the third closed configuration 370 may indicate that the automatic lacing system 24 is in a fully closed state. The first closed configuration 366 and the second closed configuration 368 may be closed intermediate states between a fully open state and a fully closed state.

Referring to fig. 18L, a low battery state 372 is shown. In the low battery state 372, all of the LEDs 332 may blink or flash to indicate to the user that the automatic lacing system 24 is operating low. In some embodiments, the automatic lacing system 24 may enter the low-battery state 372 when the battery has been depleted up to about 5% of the charge. In some embodiments, if the battery is less than 3%, automatic lacing system 24 loosens lace 142 and lace 144 to an open configuration 364 to allow the user to remove shoe 22. Referring now to fig. 18M, a charge state 374 is shown. In the charging state 374, all of the LEDs 332 are illuminated and may display a color that is different from the color of the open/

closed states

364, 366, 368, 370. While the above configurations and states have been described with respect to changing the illumination configuration of the LEDs 332, alternative variations are contemplated. For example, in some configurations or states, the LEDs 332 may blink, change different colors, blink, or blink one at a time to indicate an alternate state or configuration.
