Abstract
A fastener for releasably securing the ends of a drawstring. The fastener has two parts, one for each end of the drawstring. The parts are held together by a dovetail connection which is separated by excessive tension in the drawstring. At least one of the parts is connected to the associated end of the drawstring by a connection which resists movements of the drawstring in the direction to enlarge or loosen the string, but is easily released to permit intentional loosening of the string.
Claims4
A fastener for releasably securing first and second ends of a drawstring for hoods or caps of children's clothing or the like comprising first and second parts, a detachable tension resisting connection between said parts, said first part being fixed to said first end, said second part having a molded plastic body with integral upper, lower and intermediate flanges with aligned openings in the flanges providing a way for receiving said second end of the drawstring,
- a lever having its upper and lower ends adjacent said upper and lower flanges and having its intermediate portion with an integral connection to said intermediate flange, said intermediate flange and integral connection providing a resilient hinge of said lever to said body,
- a gripping surface on said body opposite the lower end of said lever for engaging one side of said second end of said string, said lever having its lower end opposite said gripping surface and normally positioned to engage the side of said second end of the string opposite said one side and to be pivoted by said second end of the string against said gripping surface to grip said string by force exerted by said string in one direction on said one end of said lever to thereby prevent movement of said string relative to said body in said one direction,
- and means for pivoting said lever away from said gripping surface to permit intentional movement of said string relative to said body in said one direction.
