  • Patent number: 6138475
    Abstract: An apparatus and system for securing jewelry to a person's body, or to secure together the ends of a piece of jewelry. In one embodiment, an earring back for receiving a post of an earring has a base having a base aperture therein for receiving the post, and a first primary leg extending from a first end of the base, and a second primary leg extending from a second end of the base. A first spring leg extends from the first primary leg, the first spring leg having front face having a tear-drop shaped front aperture therein for receiving the post. A second spring leg extends from the second primary leg, the second spring leg having intermediate face having an intermediate aperture therein for receiving the post. The spring legs are biased such that when the earring back is uncompressed or not under external applied compressive forces, the front aperture, the intermediate aperture, and the base aperture are in axial misalignment.

  • Patent number: 5774957
    Abstract: A clasp for use in attaching two body members together, especially pieces of jewelry, that provides secure attachment. The clasp includes a receptor member having a surface defining a slot and a connector member having a shaft, where the shaft is removably positionable in the slot to releasably connect the connector member to the receptor member. The connector member is moveable from an upright position where it can be inserted and removed from the receptor member, and a second, or seated, position, where it is resiliently restrained by the receptor member. The interaction between the connector member and the receptor member creates a connection that is not easily unintentionally released.
