A fastening device includes a case unit, a spool, a connecting unit, a knob and an engaging unit. The case unit includes a wall forming a receiving space, a partition separates the receiving space into an upper chamber and a lower chamber, a through hole located at the partition, and a base detachably connected to at least one part of the wall. The spool is located at the lower chamber. The knob is connected to the connecting unit. The engaging unit is located at the upper chamber. After the connecting unit is inserted into the spool, the through hole and the engaging unit to couple to the knob, the partition, the spool, the connecting unit, the knob and the engaging unit are connected integrally without being separated from each other while the base is separated from the at least one part of the wall.

An article with an automatic tensioning system includes a lace guide assembly. The lace guide assembly includes a lower guide member and two upper guide members that include channels for routing a tensioning member. Straps of the upper are attached to the two upper guide members. As the tensioning member is pulled into a tensioning device, the two upper guide members are pulled toward the lower guide member. This pulls on the straps and acts to tighten the upper around a foot.

Various embodiments of a system and associated methods for an improved rotary closure for tensioning a tensioned lacing element are disclosed herein. In particular, the improved rotary closure includes an adjuster component in association with a tensioning component to incrementally counter-rotate the tensioning component and a tensioned cylindrical device, enabling micro-adjustment of the rotary closure without complete de-tensioning of the tensioned cylindrical device.

The present invention relates to a lacing system for tightening a shoe upper, comprising: at least one strap, and a first and a second guiding element for coupling the strap to the shoe upper, wherein a first end of the strap is attached to a tongue portion of the shoe upper and a second end of the strap is configured to receive a portion of a shoelace, and wherein the first guiding element is arranged in a throat area of the shoe upper and the second guiding element is arranged in a sole area of the shoe upper opposite to the throat area.

A charging system can include provisions for providing power to various systems or components associated with the article of footwear. A charging system may include a charging unit with one or more components configured for use with one or more articles of footwear, where the articles of footwear can include different sizes. The components can be magnetically joined to the article in some cases. Upon connection with a power source, the article may be configured to unlace automatically. In some cases, the charging system can be used to facilitate the transfer of power to components in an automated tensioning system.

A shoe is disclosed that includes an upper having a closure mechanism that is arranged for lacing the shoe by at least one tensioning element, a rotatably arranged tensioning roller disposed within the closure mechanism, the tensioning roller being driven by an electric motor, and a closing button in communication with a control system for generating a closing signal that is configured to actuate the electric motor to lace the shoe. The closure mechanism is configured to tighten the shoe with a first level of lacing power when a first closing signal is generated and tighten the shoe with a second level of lacing power when a second closing signal is generated.

The present disclosure provides a string collecting device and an article having a string, wherein the string collecting device includes a rotating part and a string winding part configured to wind a string; the rotating part is provided with at least one movable part that is capable of moving; the movable part is configured to be engaged with the string winding part when the rotating part is rotated towards a string collecting direction, and wherein when the movable part is engaged with the string winding part, the three, namely, the rotating part, the movable part and the string winding part, are connected in synchronous rotation.

A reel based closure device for tightening an article includes a housing and a spool that is positioned within the housing. The spool is rotatable within the housing to wind a tension member about a channel of the spool. A knob is supported by the housing and is operably coupled to the spool so that rotation of the knob causes the spool to rotate within the housing. A pawl component is operably couplable to the knob. The pawl component includes one or more pawls having a pawl arm fixedly connected at a proximal end to the pawl component. A distal end of the pawl arm includes one or more pawl teeth. The pawl component includes a lip and the pawl arm includes a tab that engages with the lip of the pawl component to control radial movement of the pawl arm relative to the pawl component.

According to an embodiment, a device for tightening an article includes a housing, a spool rotatably positioned within the housing, a knob operably coupled with the spool to cause the spool to rotate within the housing, and a stop mechanism. The device is configured so that incremental rotation of the knob in a first direction causes a corresponding incremental rotation of the spool within the housing that incrementally tensions a tension member and thereby tightens the article. The device is also configured so that incremental rotation of the knob in a second direction causes a corresponding incremental rotation of the spool that incrementally loosens the tension member's tension. The stop mechanism is configured to prevent rotation of the spool in the second direction when the tension member's tension achieves or falls below a tension threshold.

Lacing engine systems, apparatus, and methods of operation are discussed. In an example, a lacing engine apparatus can include a housing, a drivetrain, and a lace take-up mechanism for retracting a length of lace cable upon activation. The drivetrain can include various reduction gears to reduce rotational speed out of the motor and power the lace take-up mechanism. The lace take-up mechanism can include structures such as a double-yoke, a radial pulley including an outer rotating disc and an inner stationary disc, a variable take-up spool, or a zip-strip mechanism.
