Abstract
According to an embodiment, a device for tightening an article includes a housing having an interior region and a spool positioned within the interior region and rotatable relative thereto. A tightening mechanism is operably coupled with the spool to cause the spool to rotate within the interior region of the housing. A tension member is coupled with the spool and is configured to be tensioned upon rotation of the spool via the tightening mechanism. The device also includes a tension limiting mechanism that allows the tension member to be tensioned via the tightening mechanism until a tension threshold is achieved. After the tension threshold is achieved, further operation of the tightening mechanism does not substantially tension the tension member due to the tension limiting mechanism.
