  • Publication number: 20110185768
    Abstract: A decorative double-sided jewelry clasp for joining two ends of a jewelry chain together. The clasp comprises a rocker plate pivotally mounted to a base plate at a hinge. The hinge is formed by cooperating yokes extending from the center of each of the rocker plate and base plate. With plates facing, the yokes align and a pin is inserted there through to pivotally secure them together. A torsion spring is carried on the pin to bias the rocker plate versus the base plate. Further, the base plate has a short post at one end and a longer hook at the other, the hook looping around to the backside of the rocker plate, and thereby stopping counter-pivoting of the rocker plate. Both hook and post catch and secure the ends of the jewelry chain, with the spring locking the chain at both ends until a user depresses the rocker plate, thereby counter-biasing it open at both ends to release the chain.
