Jewelry item, method of manufacturing a closure for jewelry item, finding for an earring, kit of parts forming the finding, and earring constructed from the kit

摘要

A jewelry item has a ring part (52) pivotally attached to a closure (56) at one end. The closure (56) spans the continuity of the ring from an end of the ring part (52) and comprises a ring continuation arm (58) extending in continuity of the ring and pivotally attached to an end of the ring part (52) at a pivoted connection (60). The closure (56) further comprises a bias arm (63) extending along with the ring continuation arm (58) along said ring continuity. The bias arm (63) comprises a spring part and a lever part (66) pivotally attached to each other. A connection (68) between said lever part (66) and the ring part (52) is rigid, so that as the ring part (52) is opened, said lever part (66) is configured to rotate inwardly towards an interior of said item. The spring part has a natural shape of smaller circumference than the ring part (52)so that once a certain extent is reached, the spring part pulls the lever part (66) towards the spring part in order to allow the spring part to attain its smaller diameter and thus establish a stable open position. The lever part (66) further on closure of the ring part (52), is configured to push the spring part outwardly towards the ring continuation arm to establish a second stable position to close the closure. Another jewelry item (70) comprising a spring arm (80) pivoted to said continuation at a first location (86) thereon and further pivoted to its ring part (72) at a second location (86) is disclosed. A method of manufacturing a closure for a jewelry item (72), a finding (214) for an earring, a kit of parts (270,272) constructed to form the finding (214) and an earring constructed from the kit of parts and a mounting are also disclosed.
