A fastening device includes a case unit including a receiving space, a spool located within the receiving space and configured for a lace to be wound therearound, and a knob covering on the case unit. The knob includes a main body made of a composite material, and a shield cover covering on the main body and made of a metal material. A rotation of the knob drives the spool to rotate in a tightening direction for tensioning the lace.

Systems and apparatus related to footwear including a modular lacing engine are discussed. In an example, a modular footwear apparatus including an upper portion, a lower portion, and a lacing engine is described. The upper portion can include a lace to adjust fit of the upper portion against a foot, the lace adjustable between a first position and a second position based at least in part on manipulation of an effective length of the lace. The lower portion can include a mid-sole and an out-sole, and the lower portion can be coupled to the upper portion at the mid-sole. The lacing engine can include a top-loading lace spool to engage a loop of the lace to enable manipulation of the effective length of the lace through rotation of the lace spool, the lacing engine received within a cavity in the lower portion.

An article of apparel providing dynamic support for an appendage of a person is discussed herein. The article of apparel can include a support garment control device configured to provide dynamic support. The support garment control device can include a control lace coupled to a support portion of the article of apparel. In an example, the support garment control device configured to apply a first tension on the control lace, lock the support garment control device at the first tension to inhibit movement of the control lace in response to detecting a change in movement of the person, and unlock the support garment control device after a pre-determined event subsequent to the change in movement of the person.

A control system for controlling tension applied to a lace cable coupled to a support structure of an adaptive support garment is discussed herein. The control system can include a lace spool, a damper mechanism, and a locking ring. The lace spool can include a lace groove to receive the lace cable and a rotary bias member to apply rotational tension to resist extension of the lace cable out of a housing holding the control system. The damper mechanism is engagable with the lace spool to generate an additional rotational tension resisting extension of the lace cable out of the housing. The locking ring is frictionally coupled to the lace spool, and the locking ring can include a lock wedge adapted to disengage the damper mechanism upon rotation into a pre-determined rotational position relative to the damper mechanism.

A control system for use within an adaptive support garment is discussed herein. The control system can include a lace spool, a ratchet mechanism, an actuator, and a control circuit. The lace spool can include a lace groove adapted to accumulate a portion of a lace cable coupled to a support structure within the adaptive support garment. The ratchet mechanism can be configured to control rotation of the lace spool during operation of the control system. The actuator can be adapted to control engagement of the ratchet mechanism. The control circuit electrically can be coupled to the actuator and can be configured to operate the actuator to engage or disengage the ratchet mechanism. In operation, rotation of the lace spool controls an effective length of the lace cable to provide adaptive support.

A fastening device includes a case, a spool and a knob. The case includes a housing and a base. The housing includes a receiving space and two side holes communicated with the receiving space. The base is detachably connected to the housing. The base includes a continuous wall, and the continuous wall surrounds a lower edge of the housing after the base is connected to the housing. The spool is received in the receiving space and configured for a lace passing through the side holes to be wound therearound. The knob is disposed on the case. Rotating the knob relative to the case in a fastening direction causes the spool to rotate in the fastening direction for fastening the lace.

The present invention discloses a string tightening device that can easily adjust the characteristics of the string, such as the length or tension of the string used in various wearing products or household items, including shoes, bags, clothing, and the like. A string tightening device of the present invention includes: a base having a space therein and including a first projection portion; a lower rotation member that is disposed in the base and moves a predetermined distance in a direction of separation from the base or the opposite direction thereof, an upper rotation member coupled to the lower rotation member, including a second locking portion corresponding to the first locking portion, and rotating only in one direction when the first locking portion and the second locking portion are closely attached; and an inner housing portion provided in the lower rotation member or the upper rotation member and wound therearound.

Various embodiments of a system for an improved rotary closure including a dial cover for ease of gripping and customizability are described herein.

An article of footwear includes a fitting system with an upper member that is supported by the upper and a strand guide that is supported by the sole structure. The strand guide is flexible and flexes in concert with the sole structure. The strand guide has a guide surface. The fitting system further includes a tensioning system with a flexible strand that is configured to bias the upper member toward the strand guide. The flexible strand has a first section coupled to the upper member and a second section extending through the sole structure. The second section abuts the guide surface. The second section is configured to slide across the guide surface as a result of flexure of the strand guide. The first section and the upper member are configured to move relative to the sole structure as a result of sliding of the second section across the guide surface.

A lace tensioning device includes a housing component having an interior region, a first aperture, and a second aperture, and a spool component that is rotatably positionable within the interior region of the housing component. The spool component has a central cylindrical member and a lumen that extends through the central cylindrical portion. The spool component is rotatable within the interior region of the housing component to align one end of the lumen with the first aperture and to align an opposite end of the lumen with the second aperture to enable a lace to be inserted through the first aperture, the lumen, and the second aperture so that opposing ends of the lace are positioned exterior to the housing component. A knot may then be tied in the lace and the lace retracted to couple the lace with the housing component and spool component.
