A closure system including a body for receiving an object. An activation device is connected to a base structure, and is activated by placement of the object within the closure system. The activation device operates between a raised or depressed configuration, depending on the position of the object within the closure system. A tightening mechanism is responsive to the operation of the activation device. When the activation device is in the raised configuration, the tightening mechanism is loose. When the user depresses the activation device, the tightening mechanism tightens around the object. A movable displacer in a locking device for locking the configuration of the closure system and removably insertable into a recess helps better control tension within the tightening mechanism and improves comfort by disengaging the activation device from the tightening mechanism. A lace lock for locking a lace is disclosed. A lace tension distributor is also disclosed.

Embodiments of the present invention provide an apparatus for convenient tightening and loosening of strings such as those found in shoelaces of footwear. The apparatus includes a rotating portion within a base portion. A cover portion, when operated in a first position, provides a ratchet movement that allows rotation in a tightening direction while preventing movement in a loosening direction. When the cover is moved to a second position, the ratchet mechanism disengages, and the strings can then be easily loosened.

A shoelace winding reel for a shoelace winding device that is compact and light weight, with superior durability and assembly workability. The shoelace winding reel is housed in a reel storing section of a base member and is configured to be rotatively driven by a dial. The shoelace winding reel includes a rotation shaft portion arranged on an inner side of the shoelace winding drum and an annular portion configured to connect an inner circumferential surface of the shoelace winding drum and an outer circumferential surface of the rotation shaft portion. An annular groove portion is configured to sandwich a tip end portion of the shoelace.

According to an embodiment, a method of assembling a reel includes coupling a drive component with a tightening component and coupling the tightening component with a top end of a housing. A spool component is then inserted within a bottom end of the housing so that the spool component is positioned within the housing's interior region and faces a bottom surface of the drive component. An attachment component is then coupled with the bottom end of the housing. The attachment component includes a coupling member that couples with the drive component. Coupling of the coupling member with the drive component operationally couples the drive component and the spool component so that operation of the tightening component causes the spool component to rotate within the housing in a first direction while preventing rotation of the spool component in a second direction.

A closure system for a boot or other footwear includes a tension member that is disposed within the boot and routed or guided about a path within the boot via one or more guides. The closure system also includes an adjustment member that is disposed within the boot and operably coupled with the tension member. The closure system further includes a reel based closure device having a knob that is operable to tension the tension member and to release tension from the tension member. Tensioning of the tension member adjusts a fit of the adjustment member about a foot within the boot to secure the foot within the boot and loosening of the tension member adjusts the fit of the adjustment member about the foot to allow the foot to be more easily removed from the boot.

A lace-tightening device for a shoe lace in a shoe comprises a rotating cam within a housing disposed within the shoe. The cam is connected to the opposite ends of the shoe lace and includes an outer surface for receiving the shoe lace as the cam rotates to pull the lace. A driven gear disposed is rotatably coupled to the cam through a one-way clutch configured so that rotation of the driven gear in one direction rotates the cam in the one direction, thereby tightening the shoe lace connected to the rotating cam. A ratchet arm is slidably disposed within the housing and includes linear teeth arranged to engage the teeth of the driven gear as the ratchet arm translates in a linear direction. to rotate the gear in the one direction. The ratchet arm is pulled by at least one shape memory alloy (SMA) wire attached at one end to the ratchet arm and at its opposite end to a controller. The controller is configured to execute a power cycle to energize and deenergize the SMA wire so that the wire sequentially shrinks and returns to its original length to thereby sequentially translate the ratchet arm in the linear direction, and ultimately to incrementally pull and tighten the shoe lace. The controller repeats the cycle a number of times until the lace reaches a tightness desired by the user.

Systems, apparatus, and methods related to an automated footwear platform including motor control techniques. The motor control techniques can include operations such as segmenting a pre-defined travel distance, defining a plurality of moves, creating a plurality of motion profiles, and commanding movements. The plurality of moves can utilize the segmented travel distance for a drive mechanism associated with the footwear platform. Each motion profile of the plurality of motion profiles can include one or more moves from the plurality of moves. Commanding movement of the drive mechanism can be based on selection of one or more motion profiles from the plurality of motion profiles.

An article of footwear, an article of apparel or protective gear can include a tensioning apparatus for tightening, for example, laces, cables or strings or other devices that secure the article to a wearer. The tensioning apparatus receives signals from an input assembly that is in communication with the tensioning apparatus. The input assembly may include pairs of wires that have twisted loops or other curvilinear segments that allow the input assembly to accommodate to different actions by the wearer of the footwear. The input assembly may also include a flexible epoxy cover that protects the connections between the wires and a printed circuit board that includes input devices.

A method of chamfering an aperture in a reel member of a tensioning system for an article of footwear is disclosed. The tensioning system includes a reel member configured to rotate about a central axis. The reel member includes a shaft and at least one flange disposed along the shaft. The flange includes an aperture extending through the flange. The aperture is configured to receive a lace. The reel member can tighten the tensioning system by winding the lace around portions of the shaft disposed on both sides of the at least one flange. The method of chamfering the aperture includes drilling through an end flange of the reel member to reach the center flange of the reel member in order to chamfer the aperture. The chamfered aperture can assist with sliding the lace through the aperture and distributing tension.

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.
