ABSTRACT:
A device for quickly tightening shoelaces on a shoe and for locking the tightened laces without the need for tying a bow or other knot is disclosed. The device includes a body unit with a slotted opening formed with a chamfered edge along one side of the slot. A rotatable shaft which includes a set of chamfered ridges rolls laterally across the width of the slot. A shoelace introduced through the slot becomes pinched between the chamfered edge of the slotted opening and the chamfered ridges of the shaft. The shaft is spring biased to automatically lock the laces in place upon being tightened to the desired tension. A quick release lever retracts the shaft to unpinch the lace.
