Abstract: A releasable buckle is described, made of molded synthetic plastic material and comprising a female part and a male part which snap-engages into a socket defined within the female part by means of a pair of longitudinal resilient arms provided with teeth which lock the buckle by cooperating with respective edges of a pair of lateral through slots formed within the female part. The male part is further provided with a central rigid arm cooperating with guide means of the socket within the female part and adapted to limit, in use, the deflection of the resilient arms. This rigid arm has a length such as to cooperate in an interfering manner when the teeth are in the engaged position within the slots, with resilient means provided upon a bottom wall of the socket of female part.

Abstract: A mechanism for releasably connecting the ends of a bracelet, necklace or watchband. The mechanism includes a male connector component slidably insertable into a female connector component. Two resiliently-biased arms on the male component ride along inturned flanges in the female connector, after which the arms spring outwardly to lock against interior side faces of the flanges. Two squeezable handles extend from the arms for moving the arms together, thereby enabling the male connector element to be withdrawn from the hollow female element.

Abstract: A plug-type clasp for pieces of jewerly, in particular for necklaces, composed of a housing in which a sleeve is movable under the force of a spring. The sleeve has a receiving opening into which a connecting element can be inserted through a front-end opening of the housing and locked there. Both the front-end opening of the housing and the receiving opening of the sleeve are eccentrically offset from each other, so that the connecting element can only be inserted into the housing, and locked there, only after the sleeve has been pulled back against the force of the spring. Removal of the connecting part can take place in the correspondingly reversed order. Activation of the sleeve for unlocking the plug-type clasp takes place by means of an operating button, laterally guided in a longitudinal hole of the housing, so that the actual connecting areas of the plug-type clasp for pieces of jewelry, in particular necklaces, remain free of pulling stresses during the operation of the plug-type clasp.

Abstract: A transferable jewelry clasp that can be worn with different chains or bands which has the shape of a ring or has a central opening and has an upper part and a lower part. These parts are connected with one another on one side by means of a hinge, and on the opposite side by means of a snap clasp. It can thus be opened and closed easily.

Abstract: A clasp with an interchangeable ornament includes a generally solid male clasp piece which is split longitudinally in a manner that it is transversely resilient, like a clip. A hollow female clasp piece has an insertion opening and an inwardly indented shoulder or lip at the insertion opening. When the male clasp piece is inserted into the female piece the shoulder of the female piece locks into a groove formed in the male clasp piece. Longitudinally extending slits in the peripheral wall of the female piece makes it transversely elastic and enables it to tightly hold an interchangeable ornamental sleeve that is fitted over the female piece. The ornamental sleeve in turn prevents the slit peripheral wall of the female piece from separating and assures that the inwardly indented shoulder remains locked in the groove of the male piece.

Abstract: A gold jewelry clasp assembly is described, which includes a keeper for receiving a catch and retainer, wherein all of the elements are constructed to operate reliably over a long life time. The catch is formed of a tempered gold strip bent at its middle to form a folded leaf spring, and with one end of the strip bent into a loop around a pivoting wire retainer. The bending avoids a gold soldering operation on the strip which could degrade spring temper, and also permits welding of the retainer wire ends prior to attachment to the catch to facilitate heat sinking that minimizes loss of spring temper of the retainer. The keeper is formed of a drawn tub-shaped gold frame, with the edge that forms the opening of the tub-shaped frame, being cut away at opposite ends to leave a pair of projecting lips on opposite sides. A gold cover strip covers the opening of the frame, and the cover strip has a recess on either side that receives the frame lips in an interference fit.
