Description

Articles of Footwear with Automatic Lacing Systems

FIELD OF THE INVENTION The present disclosure relates generally to articles of footwear that include an automated lacing system that includes an electronic assembly for automatically tightening or loosening one or more laces.

Many conventional footwear or articles of footwear generally include an upper and a sole attached to the bottom of the upper. Conventional footwear further includes an interior space for receiving a user's foot prior to securing the footwear to the foot, ie, a cavity or void created by the interior surfaces of the upper and sole.

The sole is attached to the lower surface of the upper and is positioned between the upper and the ground. As a result, the sole generally provides stability and cushioning to the user when the shoe is being 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 the bottom surface of the sole, the midsole may attach to the interior surface of the outsole, and may provide cushioning and/or added stability to the sole.

For example, the sole may include certain foam materials that may increase stability in one or more desired locations along the sole, or stress or impact on the foot and/or leg as the user runs, walks, or engages in other activities. It may include a foam material that can reduce energy.

The upper generally defines an interior cavity that extends upwardly from the sole and completely or partially encloses the foot. In most cases, the upper extends across the instep and toe areas of the foot and the medial and side portions of the foot. Many articles of footwear may also include a tongue extending across the instep region to bridge a gap between the edge of the side portion and the medial portion of the upper defining an opening into the cavity.

A tongue may also be disposed below the lacing system and between the medial and sides of the upper, wherein the tongue is provided to allow adjustment of shoe tightening. The tongue may also be manipulated by the user to allow entry and/or exit of the foot from the interior space or cavity.

The lacing system also allows the user to adjust certain dimensions of the upper and/or sole, allowing the upper to accommodate a variety of foot types having different sizes and shapes.

The upper may include a wide variety of materials that may be selected based on one or more intended uses of the shoe. The upper may also include portions comprising various materials specific to particular regions of the upper. For example, the added stability may be desirable at the front of the upper or adjacent the heel region to provide a higher degree of resistance or rigidity.

In contrast, other portions of the shoe may include a soft woven textile to provide areas with stretch, flexibility, breathability or moisture-wicking properties.

Additionally, lacing systems associated with typical footwear historically included a single lace pulled through a plurality of holes in a crisscross or parallel fashion.

Many shoes have historically included laces that extend from one side of the upper to the other, ie from the medial to the side of the upper. The laces on each shoe are laced through the eyelets, and the two ends of the lace extend out of the eyelets so the user can grab the ends and tie the shoe in any way the user sees fit.

Some shoes include elastic laces that don't need to be tied, and that the laces stretch when you put them on and return to their original tightness when you take them off. In addition, there are shoes without laces, such as slip-on shoes, and there are shoes with straps that can adjust the degree of tightness of the shoes. With respect to shoes that include lace, it may be desirable to utilize a system that can automatically lace up the shoe, for example in situations where a user may want the adjustability of the lace in various situations. It may also be desirable to have an automatic lacing system for users who have difficulty tying shoe laces, such as the elderly or the weak.

It may also be desirable for the lace to include a lacing system that does not apply forces along the top of the foot; Rather, the force is applied along the medial and lateral sides of the foot when tightening the lace. It may also be desirable to include a system capable of automatically lacing shoes via a graphical user interface displayed on a portable electronic device.

Accordingly, there may be a need for an article of footwear having an upper with an automatic lacing system.

For reference, article of footwear 44 defines a forefoot region 56 , a midfoot region 58 , and a heel region 60 (see FIGS. 6A and 6B ). Forefoot region 56 generally corresponds to the portion of article of footwear 44 that surrounds a portion of the foot including the toes, cheeks of the foot, and toes or joints connecting the phalanx and metatarsal bones. Midfoot region 58 is proximate to and adjacent to forefoot region 56 , and corresponds to the portion of article of footwear 44 that surrounds the arch of the foot generally along the leg of the foot. Heel region 60 corresponds to the portion of article of footwear 44 proximate to and adjacent to midfoot region 58 and that generally surrounds the heel or posterior portion of the foot including the calcaneus, ankle, and/or Achilles tendon.

Many conventional shoe uppers are formed from multiple elements joined through bonding or stitching at seams, for example, fabric, polymer foam, polymer seat, leather and/or synthetic leather. In some embodiments, upper 50 of article of footwear 44 is formed from a knitted structure or knitted component. In various embodiments, knitted components may include various types of yarns that may provide different properties to the upper. For example, one area of upper 50 may be formed of a first type of yarn imparting a first set of properties, and another area of upper 50 may be formed of a second type of yarn imparting a second set of properties. can be Using this configuration, the properties of upper 50 can be varied throughout upper 50 by selecting specific yarns for different areas of upper 50 . In a preferred embodiment, and with reference to FIG. 8 , article of footwear 44 may include a first or mesh layer 62 and a second or base layer 64 . The base layer 62 may include multiple layers, such as an exterior surface 66 that may be provided with a plurality of apertures 68 and an interior surface 70 that engages the foot when a user wears the article of footwear 44 on. can Mesh layer 62 and base layer 62 may be connected at one or more locations along article of footwear 44 .

With respect to the material(s) that make up upper 50 , the particular properties that a particular type of yarn will impart to an area of a knitted component may depend, at least in part, on the material from which the various filaments and fibers of the yarn are formed. For example, cotton can provide a soft effect, biodegradability, or natural aesthetic to a knitted material. Elastane and stretch polyester can provide knitted components with desired elasticity and resilience, respectively. Rayon can provide a high gloss and hygroscopic material, wool can provide increased moisture absorption, nylon can be a durable material with abrasion resistance, polyester can provide a hydrophobic, durable material.

Other aspects of the knitted component may also be altered to affect the properties of the knitted component and provide desired attributes. For example, the yarns making up the knitted component may include monofilament yarns or multifilament yarns, or the yarns may each include filaments formed from two or more different materials. In addition, knitted components may be formed using specific knitting processes to impart regions of the knitted component with specific properties. Accordingly, both the material forming the yarn and the other aspects of the yarn may be selected to impart various properties to a particular area of upper 50 .

In some embodiments, the elasticity of a knit structure may be measured based on comparing the width or length of the knit structure in a first unstretched state to the width or length of the knit structure in a second stretched state after knitting. The structure has a force applied laterally to the knit structure. In other embodiments, upper 50 may also include additional structural elements. For example, in some embodiments, a heel plate or cover (not shown) may be provided in heel region 60 to provide additional support to the user's heel. In some cases other elements, such as plastic materials, logos, trademarks, etc., can also be applied and secured to the exterior surface using adhesives or thermoforming processes. In some embodiments, properties associated with upper 50, for example, stitch type, yarn type, or properties associated with different stitch types or yarn types, such as elasticity, aesthetic appearance, thickness, air permeability or scratch resistance, may vary. can

A spool (not shown) is formed by the bottom surface of the wheel gear 210 and is operable to spool the first race 142 and the second race 144 . A portion of the housing 140 is removed for clarity. Although specific gear configurations will be discussed below, a motor 216 is operable to rotate a worm gear 212 via a gear train 214 . The worm gear 212 is configured to drive the wheel gear 210 , which causes the first race 142 and the second race 144 to rotate about the wheel gear shaft 218 . As wheel gear 210 rotates and pulls first race 142 and second race 144 about axis 218 coincident with the axis of the spool, races 142 and 144 engage wheel gear 210 (and expand, tighten or loosen depending on the rotational direction of the worm gear 212, the gear of the gear train 214, and the motor 216). As will be described later, the motor 216 may be a DC brushless motor.

Specifically, referring to FIG. 9A , the wheel gear 210 has a first aperture 220 and a second aperture 222 on the side or right side 224 , and a third aperture on the inside or left side surface 230 ( 230 ). 226 ) and a fourth aperture 228 .

In the preferred embodiment, the second lace 144 passes through the housing 140 and drags upwards through the third aperture 226 and downwards again through the fourth aperture 228 . This orientation is such that the first race 142 and the second race 144 move around the gear axis 218 by arrows, depending on whether the automatic lacing system 24 is used to tighten or loosen the races 142 , 144 . Allow it to be pulled inward in the A or B direction. As can be seen from the orientation of the first race 142 and the second race 144 along the wheel gear 210 , the first race 142 and the second race 144 are simultaneously in this orientation to the same extent. Tighten or loosen

In a preferred embodiment, from an initial or loose configuration (shown in FIG. 9A ), approximately 90 degree rotation of wheel gear 210 results in a first level of tightening, and approximately 180 degree rotation of wheel gear 210 results in a second This will result in a tightness level, rotation of the wheel gear about 270 degrees will bring the tightness level to the third level, etc. In some embodiments, rotation of the wheel gear 210 in increments of about 60 degrees results in a first level of tightening, a second level of tightening, a third level of tightening, and the like. In some embodiments, rotation of the wheel gear 210 in increments of about 45 degrees results in a first level of tightening, a second level of tightening, a third level of tightening, and the like. In some embodiments, rotation of the wheel gear 210 in increments of about 30 degrees results in a first level of tightening, a second level of tightening, a third level of tightening, and the like. In some embodiments, rotation of the wheel gear 210 in increments of about 15 degrees results in a first level of tightening, a second level of tightening, a third level of tightening, and the like.

Still referring to FIG. 9A , the worm gear 212 defines a worm gear shaft 238 on which the first gear 240 , which is one of the gears of the gear train 214 , is disposed. 9B, the motor housing 242 (refer to FIGS. 11 and 12) of the housing 140 is shown in a removed state, and the gear base 244 of the housing 140 is coupled to the wheel gear 210. shown in the state of being In FIG. 9B , the first gear 240 is visible along with the wheel gear 210 and the worm gear 212 , but the remaining gears of the gear train 214 are covered 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. 9B and 10B , gear train 214 and gear train housing 246 are disposed along the sides of the footprint of housing 140 . Further, the motor 216 is disposed at the heel end of the footprint of the housing 140 , and the wheel gear 210 is provided at the midfoot end of the footprint of the housing 140 .

Referring now to FIGS. 10A and 10B , a ghost view of some internal components of the automatic racing system 24 illustrates a wheel gear 210 , a worm gear 212 , a gear train 214 , and a motor 216 . . Specifically, referring to FIG. 10A , the wheel gear 210 has a first aperture 220 and a second aperture 222 on the right side 224 , and a third aperture 226 and a fourth aperture on the left side 230 . It includes an aperture 228 . The first and second apertures 220 and 222 are disposed adjacent to each other, and the third and fourth apertures 226 and 228 are disposed adjacent to each other. 10A and 10B , the first lace 142 passes into the housing 140 , upwards through the first aperture 220 , and through the third aperture 226 . is tied down again through the In the same embodiment, the second lace 144 is passed into the housing 140 , tied upwards through the second aperture 222 , and tied down again through the fourth aperture 228 . This orientation is such that the first race 142 and the second race 144 move around the gear axis 218 by arrows, depending on whether the automatic lacing system 24 is used to tighten or loosen the races 142 , 144 . Allow it to be pulled inward in the A or B direction. As can be seen from the orientation of the first race 142 and the second race 144 along the wheel gear 210 , the first race 142 and the second race 144 are simultaneously in this orientation to the same extent. Tighten or loosen

11-15 show the elements of the automatic lacing system 24 in an exploded configuration. Referring specifically to FIG. 11 , an exploded perspective view of some components of the automatic lacing system 24 is shown. The components include a top cover 250 , a gear base 244 , a motor housing 242 , a gear train housing 246 , a wheel gear 210 , a worm gear 212 , and a gear train 214 . The worm gear 212 is provided 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 include 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 shaft 262 . Since the second gear 258 and the third gear 260 are fixedly coupled to each other, when the second gear 258 rotates, the third gear 260 also rotates. A third gear assembly 264 is also provided, which includes 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 the third shaft 270 . A motor gear 272 is also shown extending from the motor 216 , which is disposed along the 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 gears or straight cut gears include cylinders or discs with radially projecting teeth. Although the teeth are not straight, the edges of each tooth are straight and aligned parallel to the axis of rotation. When two gears, for example, the first gear 240 and the third gear 260 are meshed, if one gear is larger than the other gear (the first gear 240 has a larger diameter than the third gear 260 ) ) The rotational speed and torque of the two gears vary in proportion to their diameter, creating a mechanical advantage. Since the larger gear rotates less quickly, the torque thereof is proportionally greater, and in this example, the torque of the third gear 260 is proportionally greater than the torque of the first gear 240 .

Still referring to FIGS. 11-15 , first gear assembly 254 includes worm gear 212 in communication with wheel gear 210 . A worm gear is a type of helical gear, but the helix angle is usually rather large (close to 90 degrees) and the body is usually quite long in the axial direction. As will be appreciated by those skilled in the art, the use of the worm gear 212 results in a simple and compact way to achieve a high torque, low speed gear ratio between the worm gear 212 and the wheel gear 210 . In this embodiment, the worm gear 212 can always drive the wheel gear 210, but not always the other way around. The combination of the worm gear 212 and the wheel gear 210 results in a self-locking system, and thus an advantage is achieved, i.e. the worm gear 212 can be easily used to maintain its position when a certain level of tightening is required. have. The worm gear 212 may be right or left-handed. For purposes of this disclosure, the worm gear assembly 276 includes a wheel gear 210 , a worm gear 212 , a first shaft 252 , and a first gear 240 . Worm gear 212 , first shaft 252 , and first gear 240 may comprise a single material or may comprise different materials.

The worm gear assembly 276 communicates with a second gear assembly 256 that communicates with a third gear assembly 264 that communicates with the motor gear 272 . As a result, when the motor shaft 274 is rotated by the motor 216, the motor gear 272 determines whether the wheel gear 210 is rotated clockwise or counterclockwise, i.e., the first race 142 and the second 2 Rotate clockwise or counterclockwise depending on whether the lace 144 is intended to tighten or loosen. The motor gear 272 communicates with the fifth gear 268 , and the third shaft 270 and the fourth gear 266 rotate by the rotation thereof. The fourth gear 266 communicates with the second gear 258 fixedly coupled to the third gear 260 . As described above, the second gear 258 , the third gear 260 , and the second shaft 262 include a second gear assembly 256 .

11-15 , the second gear assembly 256 is caused to rotate by the third gear assembly 264 when caused by the motor gear 272 to rotate. Since the third gear 260 of the second gear assembly 256 communicates with the first gear 240 , the rotation of the third gear 260 causes the rotation of the 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 to the worm gear 212 . do. Accordingly, when the first gear 240 is rotated, the worm gear 212 is rotated. Since the wheel gear 210 communicates with the worm gear 212 , when the first gear assembly 254 rotates, the wheel gear 210 also rotates. As wheel gear 210 rotates, first race 142 and second race 144 are pulled into the housing about wheel gear shaft 218 or spool. As mentioned above, the first gear assembly 254 includes a first gear 240 , a first shaft 252 , and a worm gear 212 . The worm gear assembly 276 includes a first gear assembly 254 and a wheel gear 210 . To this end, when the motor gear 272 rotates, the third gear assembly 264 rotates, the second gear assembly 256 rotates, and the worm gear assembly 276 rotates.

Referring now to FIGS. 11 and 12 , the motor housing 242 , the base 244 , the gear housing 140 , and the top cover 250 of the housing 140 are shown in detail. Motor housing 242 includes race apertures 280 on its left and right (or inside and side) sides, and gear train apertures 282 along its right (or sides). Race aperture 280 allows first race 142 and second race 144 to enter motor housing 242 undisturbed. Motor housing 242 further includes an outer platform 284 surrounding motor compartment 286 .
