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.

According to one embodiment, a removable tightening device is described. The tensioning mechanism is removably coupleable with an article without damaging the article so that upon removal, the coupling of the tensioning mechanism with the article is unrecognizable or not readily detectable. The tensioning mechanism is operable with a tension member to maintain a tension of the tension member and thereby maintain a tightness of the article. The tension member is guided along a path about the article, via one or more guide members, and is tensionable, via the tensioning mechanism, to tighten the article.

A shoe includes a sole and an upper that is attached to the sole. The upper has a first side and a second side that fit around a wearer's foot when the shoe is fit about the wearer's foot. The shoe also includes a strap or panel having a proximal end that is attached to one side of the shoe and a distal end that extends toward an opposite side of the shoe. A tension member is guided or directed about a path along the shoe and a tightening mechanism is operable with the tension member to effect tensioning of the tension member. The strap or panel includes a first guide and a second guide and the tension member is routed through both the first guide and the second guide of the strap or panel.

This disclosure relates to articles that include a tightening mechanism, such as reel-based lace tightening mechanism, configured to tighten the article by rotation of a knob. The articles can include a concealing portion that is configured to conceal or protect at least a portion of the tightening mechanism, such as the knob. The concealing portion can be configured to prevent unintentional actuation of the tightening mechanism, such as during contact sports. The concealing portion can be configured to hide the tightening mechanism from view to improve the visual appearance of the article. The concealing portion can be collapsible such that a user can press the concealing portion down to expose the knob of the tightening mechanism.

A reel based closure device includes a base, a housing, a spool positioned within an interior of the housing, and a knob that is operably coupled with the spool. The spool is rotatable in a first direction to wind a tension member about the spool and is rotatable in a second direction to unwind the tension member from about the spool. The knob is coupled with the spool so that a rotation of the knob causes the spool to rotate in the first direction. The base is coupleable with the housing in a manner such that a material, such as fabric, is disposed between the base and housing. Coupling the base with the housing with the material disposed therebetween enables the reel based closure device to be quickly and easily attached to an article, such as footwear.

A reel based closure device includes a base having a recess and a housing coupled with the base. The reel based closure device also includes a spool rotatably positioned within the housing and a dial or knob that is operably coupled with the spool. The reel based closure device further includes an automatic winding mechanism that is positioned in the recess and coupled with the spool to cause or effect at least a temporary automatic winding of the tension member about the spool.

A tightening device for tightening a ski boot includes an elongate panel having a proximal end and a distal end. The elongate panel is positioned about the ski boot's shell between opposing sides of the shell. A tensioning mechanism is coupled with the proximal end of the elongate panel. A tension member is operably coupled with the tensioning mechanism so that an operation of the tensioning mechanism adjusts a tension of the tension member. At least one guide member is coupled with, or positioned on, the proximal end of the elongate panel adjacent to the tensioning mechanism. The tension member is coupled with the guide member to route or direct the tension member between the opposing sides of the shell and along a portion of the elongate panel.

A reel based closure device includes a housing, a spool positioned within the interior region of the housing, a knob that is operably coupled with the spool and with the housing, and a rotation control component that is operably coupled with the knob. The knob is rotatable in a tightening direction to cause the spool to rotate within the housing and thereby wind the tension member about the spool. The knob is also rotatable in a loosening direction to cause the spool to rotate in an opposite direction within the housing and thereby unwind the tension member from about the spool. The rotation control component is configured to prevent accidental loosening of the tension member by inhibiting rotation of the knob in the loosening direction until a sufficient rotational force is exerted on the knob in the loosening direction.

A reel for tightening an article includes a housing and a spool positioned within the housing. A knob is coupled with the spool to cause the spool to rotate within the housing and thereby wind a tension member about a central post of the spool. A load holding mechanism is coupled with the spool and the housing and includes a first friction element and a second friction element that are frictionally engageable to prevent rotation of the spool in a second direction to prevent unwinding of the tension member from the spool's central post. Rotation of the knob in a first direction reduces frictional engagement of the friction elements to enable rotation of the spool in the first direction and tension in the tension member biases the spool toward rotation in the second direction which increases the frictional engagement of the friction elements.

A tension member guide that is configured to direct or route a tension member about a path of an article includes a cover member and a guide member that is partially covered by the cover member. The cover member is attachable to the article and includes a pair of slits or incisions. The guide member is folded along a longitudinal length to form a loop or channel within which the tension member may be inserted. The guide member is positioned in relation to the cover member so that opposing end portions of the loop or channel are inserted through the slits or incisions such that the opposing end portions are positioned on an opposite side of the cover member from a remainder of the guide member.
