发明名称 Shoe lace tightener
摘要 A shoe lace tightener in which a housing open at the top and back and closed at the front, sides and bottom has a spindle extending from front to back on which the hub of a reel for a shoe lace is journaled. A spring biases the reel in the direction to retract the lace by winding on the reel. A lever at the top of the housing unlocks the lace to permit winding and unwinding of the lace and locks the lace in the desired position. A clip with sides straddling the side walls of the case has a back section partially closing the back of the case and holding the hub and lever in the case.
