Abstract
A magnetic clasp having first and second magnetized portions, each with a hole disposed in the center thereof. The two portions are magnetically attractive to each other but are divided with a gap at their interface to permit easy separation thereof. A third magnetic portion is sized to fit within the hole in the first and second rings. The magnetic prevents lateral movement of the two portions at their interface. The male portion has attached to its opposite ends a chain, each end of the chain being further attached to a stop sized larger than the hole in the rings.
Claims13
A magnetic clasp for fastening jewelry comprising:
- a plurality of magnetic clasp portions defining at least one magnetic interface having a strong magnetic attraction in a direction normal to said interface;
- means for fastening said jewelry to said magnetic clasp portions;
- means passing through said interface engaging said clasp portions for providing a mechanical resistance to the separation of said portions by a force parallel to said interface;
- and
- a plurality of protrusion means at said interface for establishing a gap between said portions for reducing the effort required to release said clasp.

A magnetic clasp for fastening jewelry comprising:
- a plurality of magnetic clasp portions defining at least one magnetic interface having a strong magnetic attraction in a direction normal to said interface;
- means for fastening said jewelry to said magnetic clasp portions;
- means at said interface for providing a mechanical resistance to the separation of said portions by a force parallel to said interface;
- and
- means at said one interface for establishing a gap between said portions for reducing the effort required to release said clasp;
- wherein said plurality of magnetic clasp portions comprises:
- a first clasp portion, said first clasp portion comprising a magnet having a north and south polarity, and an interface surface structure comprising at least a portion of said magnet with said north polarity;
- and
- a second clasp portion, said second clasp portion comprising a magnet having a north and south polarity, and an interface surface structure comprising at least a portion of said magnet with said south polarity;
- and
- wherein said interface surface structure of one of said first and second clasp portions comprises male protrusion means and the interface surface of the other of said clasp portions comprises female receptor means, said male and female means being aligned and sized so that when said interface surfaces are joined by magnetic force, a gap is established at the interface and said mated male and female portions act to mechanically prevent a separation of said portions by a force in any direction parallel to said joined interface surface structures.
