Abstract
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.
