A footwear lacing apparatus can comprise a housing structure, a spool and a drive mechanism. The housing structure can comprise a first inlet, a second inlet, and a lacing channel extending between the first and second inlets. The lacing channel can comprise a spool receptacle located between the first and second inlets, a first relief area located between the spool receptacle and the first inlet, and a second relief area located between the spool receptacle and the second inlet. The first and second relief areas can be linearly tapered between the spool receptacle and the first and second inlets, respectively. The spool can be disposed in the spool receptacle of the lacing channel. The drive mechanism can be coupled with the spool and adapted to rotate the spool to wind or unwind a lace cable extending through the lacing channel and through the spool.

The specification discusses various lacing engine configurations for use in an automated footwear platform. For example, lacing engines with mechanisms to detect lace cable position and/or lace cable tensions are discussed. In an example, the lacing engine can include a housing, a lace spool and a detection mechanism. The lace spool can be at least partially disposed within the housing, and be adapted to collect a portion of the lace cable in response to rotation in a first direction during tightening of the footwear platform. The detection mechanism can detect a state of the lace cable manipulated by the lacing engine.

A reel based tensioning device includes a housing, a spool that is rotatably positioned within the housing, and a knob member that is operably coupled with the spool to cause the spool to rotate in a first direction within the housing and thereby wind a tension member about the spool. The reel based tensioning device also includes a load holding mechanism that is coupled with the spool and that is configured to rotate the spool in the first direction within the housing and to prevent rotation of the spool in a second direction to prevent unwinding of the tension member from about the spool. The reel based tensioning device further includes an audible component that is configured to produce an audible noise responsive to operation of the knob member to signal an adjustment of the tension member.

An article of footwear facilitates relatively easy donning and removal, and secure adjustment. The article of footwear comprises a sole structure, an upper secured to the sole structure, and a plurality of tensioning cables having proximal ends fixed to at least one of the upper or the sole structure and extending out of the upper. A strap has a proximal end connected to distal ends of the plurality of tensioning cables, and has a distal end releasably securable to the upper to tighten the tensioning cables. A webbed spacer is secured to the plurality of tensioning cables. The webbed spacer extends between adjacent ones of the plurality of tensioning cables, and the adjacent ones of the plurality of tensioning cables spaced apart from one another by the webbed spacer.

Systems and apparatus related to automated tightening of a footwear platform including a footwear lacing apparatus are discussed. In an example, a footwear lacing apparatus can include a housing structure, a spool, and a drive mechanism. The housing structure can include a top section and a bottom section. The spool can include a superior surface, a lace spool under the superior surface and a spool shaft with a keyed connection pin. The spool can also be integrated into the top section of the housing structure. The drive mechanism can couple with the spool via the keyed connection pin on the spool shaft. The drive mechanism can be adapted to rotate the spool to tighten or loosen a lace cable integrated into the footwear.

A novel lacing device and an anti-reverse mechanism thereof are provided. The lacing device uses a novel swing arm-stop piece-gap mechanism as the anti-reverse mechanism, and the anti-reverse mechanism has double self-locking functions and a reverse deviation limiting function. Three effects are integrated, such that the lacing device using the novel anti-reverse mechanism not only has excellent hand feeling when the lace is tensioned, but also can effectively avoid the accidental loosening of the lace, and has excellent use reliability and durability.

Provided is a winding device configured so that the entirety of the device can be thinned and looseness of an elongated member can be reduced. In a winding device 1A, a flat motor 2 is used as a motor, and a spool 3 and a magical planetary gear mechanism 4 are formed flat along an extending XY plane of the flat motor 2. Thus, the entirety of the device can be configured flat, and can be thinned. Moreover, the magical planetary gear mechanism 4 prevents rotation of the spool 3 by external force, and therefore, looseness of the elongated member can be reduced.

Systems, apparatus, and methods related to an automated footwear platform including motor control techniques. The motor control techniques can include operations such as operating a motor to produce different operating characteristics based on incoming battery voltage. More specifically, the control technique compares incoming battery voltage to a threshold voltage and selects from at least two target operating characteristics. If the voltage transgresses the threshold the motor is controlled to produce a first operating characteristic, and if the voltage does not transgress the threshold the motor is controlled to produce a second operating characteristic.

In an example, a lacing engine apparatus can include a housing and a drivetrain. The housing can be securable within a footwear article. The drivetrain can include a motor, a sun gear, a planet gear, a rotating ring gear, and a spool. The spool can be secured to the ring gear and can be rotatable therewith. The spool can be configured to control a lace of the footwear article and can be configured to wind the lace as the ring gear rotates in a first direction.
