Abstract
A jewelry closure includes a pair of magnetic closure members for magnetically engaging together and a mechanical closure which acts as a second closure or safety feature. One or both closure members includes a magnet. A first closure member of the pair is supported by a casing which extends outwardly to receive the second closure member for magnetic engagement of the members. A mechanical closure acts as a safety feature preventing the two members from being readily separated. The mechanical closure may include screw threaded portions on both the casing and the second closure member or may include a push-click mechanism on the casing and second closure member.

A jewelry closure comprising:
- a magnetic closure comprising first and second closure members for engaging together magnetically, wherein at least one of said first and second closure members comprises a magnet;
- a casting for supporting said first closure member and extending outwardly for engaging said second closure member;
- and
- a mechanical closure on said casing for engaging said second closure member when said second closure member is held by magnetic attraction to said first closure member, wherein said mechanical closure comprises screw threads on said casing for engaging with complementary screw threads on said second closure member;
- wherein both said magnetic closure and said mechanical closure must be released in order to open the jewelry closure.
A jewelry closure comprising:
- a magnetic closure comprising first and second closure members for engaging together magnetically, wherein at least one of said first and second closure members comprises a magnet;
- a casing for supporting said first closure member and extending outwardly for engaging said second closure member;
- and
- a mechanical closure on said casing for engaging said second closure member when said second closure member is held by magnetic attraction to said first closure member, wherein said mechanical closure comprises an annular protrusion extending circumferentially around an outer surface of said second closure member and a plurality of protrusions extending around an inner surface of said casing whereby said second closure is pushed into said casing and said annular protrusion is pushed past said plurality of protrusions to form a mechanical engagement between said second closure member and said casing;
- wherein both said magnetic closure and said mechanical closure must be released in order to open the jewelry closure.
