Description

FIELD OF THE INVENTION

The present invention relates to jewelry and, more particularly, to magnetic jewelry clasps.

DESCRIPTION OF RELATED ART

Fastening and unfastening necklaces behind the neck with conventional jewelry clasps is extremely difficult for most women, particularly older women and arthritis sufferers. Even younger women with good finger dexterity are unable to fasten most bracelet clasps without help, because often the clasp must be fastened with one free hand.

Magnetic clasps have been introduced that are much easier to fasten and unfasten. However, magnetic clasps can open and the jewelry item lost, especially if the jewelry item gets caught on something or the magnets are attracted to iron or steel objects. For this reason magnetic clasps with safety catches have been introduced. Available magnetic clasps with safety catches are relatively difficult to open and close. The magnetic interlocking arrangement is often, not very secure. In addition some are simply not attractive and therefore not very suitable for an ornamental item such as jewelry.

Therefore, there is need for an improved magnetic clasp with an improved safety catch. The clasp should be easy for the wearer to open and close, yet secure and attractive.

SUMMARY OF THE INVENTION

A magnetic jewelry clasp is described that comprises a first body member and a second body member that are magnetically connected to each other. The clasp includes a safety catch that is movable from an unlatched position to a latched position to prevent separation of the first and second body members in their locked position. The catch can be either magnetic or mechanical.

The first body member defines a first open end and a first closed end. The first body member includes a first magnet that has a north pole and south pole that are respectively flush with the first closed end and first open end. The first open end defines a first magnetically attractive surface.

The second body member defines a second open end portion and a second closed end portion. The second body member includes a second magnet that has a north pole and south pole that are respectively flush with the second open end and second closed end. The second open end defines a second magnetically attractive surface, with the pole on the open end (either North or South) different from the pole on the open end of the first body.

The safety catch has a hinged end that is pivotally affixed to the first closed end of the first body member. The safety catch has a free end that includes a first protuberance and a second protuberance that respectively extend up and down from the free end. The first protuberance is adapted to facilitate opening and closing the clasp with at least one finger of a user while moving the catch between the open and closed positions with a finger. The second protuberance helps to hold the two bodies securely together. In some embodiments the catch may include a pair of side panels that preferably extend downward from the catch.

The first magnetically attractive surface defined by the first body member and second magnetically attractive surface defined by the second body member magnetically attach to each other and define a first locking arrangement of the clasp. The second protuberance reaching down the closed end of the second body provides a second locking mechanism. In some embodiments the safety catch aim is or includes a magnet or magnets providing a third locking mechanism. The side panels defined by the catch in some embodiments prevent misalignment of the first and second body members away from the central axis.

In another implementation, a jewelry clasp comprises: a first body member, the first body member securing a first magnet, the first magnet having a first magnetic surface being positioned at an open end of the first body member, the first body member including a first top surface and a first bottom surface wherein the first top surface and the first bottom surface are plane; a second body member, the second body member for securing a second magnet, the second magnet having a second magnetic surface being positioned at an open end of the recess, the first magnetic surface being opposite polarity of the second magnetic surface, the second body member including a second top surface and a second bottom surface wherein the second top surface and the second bottom surface are plane; a first safety clasp, the first safety clasp includes a free end, a hinged end, a first section and a second section, the hinged end of the first safety clasp being secured to the first top surface of the first body member, the first safety clasp having a perimeter defined by the first section extending from the hinged end and inwardly constricts along a central axis up to the second section and the second section outwardly extends from the first section and tapers to a tapered point at the free end; a second safety clasp, the second safety clasp includes a free end, a hinged end, a first section, a second section and a third section, the hinged end being secured to a second portion of the first body member, the second safety clasp having a perimeter defined by the first section extending from the hinged end and inwardly constricts along a central axis up to the second section and the second section outwardly extends from the first section and tapers to a tapered point at the free end; a first bump on the top surface of the second body member, the first bump having a first height; a second bump on the bottom surface of the second body member, the second bump having a second height; a first locking arrangement wherein the first magnetic surface of the first magnet is magnetically attracted the second magnetic surface of the second magnet; a second locking arrangement wherein the first height of the first bump is long enough to allow the first bump to get locked within the perimeter of the first safety clasp; and a third locking arrangement wherein the second height of the second bump is long enough to allow the second bump to get locked within the perimeter of the second safety clasp.

The jewelry clasp can also have the hinged end of the first safety clasp being in proximity to the open end of the first body member and the hinged end of the second safety clasp being in proximity to the open end of the second body member. The jewelry clasp can also have the first bump be a ball-shaped configuration that extends in a plane substantially perpendicular to the central axis and the second bump can be a ball-shaped configuration that extends in a plane substantially perpendicular to the central axis.

DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION

Although specific ten is are used in the following description for sake of clarity, these terms are intended to refer only to particular structures of the invention selected for illustration in the drawings, and are not intended to define or limit the scope of the invention.

Referring initially to FIGS. 1 and 2, a jewelry clasp 10 is shown that includes a first body member 12 and a second body member, 14 that are configured to be aligned along a central transverse X-axis. The clasp 10 includes a safety catch 16 that is preferably hingedly attached to the first body member 12 to substantially lock the first body member 12 with the second body member 14. The first body member 12, second body member 14 and safety catch 16 are preferably made of materials of high strength and resiliency such as stainless steel, preferably feritic stainless steel, or other magnetic stainless steel. These materials will enhance the magnetic attraction of magnets 28 and 50. It is understood, however, that the material of construction of body members 12, 14 can vary as per the intended use of clasp 10 and can be made of ornamental and precious materials such as gold, silver or platinum. The clasp can also include precious stones, such as diamonds, rubies or emeralds; or other ornamental materials such as glass crystals.

First body member 12 and second body member 14 have their lateral distal ends respectively connected to rings 18, 20. The rings 18, 20 are preferably adapted to affix clasp 10 to a free end of a jewelry article such as, for example, a chain, a necklace, a bracelet and an anklet. The rings 18 and 20 in this one preferred embodiment are connected to bodies 12 and 14 and clasp 10 using conventional methods such as, but not limited to, soldering and crimping. The rings 18 and 20 in this one embodiment are of circular shape, however, it is understood that the rings 16 can be of any shape, such as oval, rectangular, and elliptical, for example. The rings can also be eliminated and the clasp built in to jewelry items, such as necklaces and bracelets by the manufacturer.

First body member 12 is bilaterally disposed along a central axis-A that is preferably adapted to be substantially aligned with the central transverse X-axis referring to FIGS. 3 and 4. First body member 12 has a first open end portion 22 and a first closed end portion 24. The first open end portion 22 defines a cavity or recess 26 within the first body member 12 that is preferably adapted to accommodate a magnet 28. Magnet 28 is adhesively secured into recess 26. However, it is understood that magnet 28 can be secured within recess 26 using alternative techniques such as, for example, crimping and laser soldering. Magnet 28, in this one preferred embodiment, is preferably made of permanent magnetic material such as Sintered Neodymium Iron Boron (NdFeB) N50, although it is understood that magnet 28 can be also made of permanent magnetic materials such as, for example. Samarium cobalt, Alnico ceramic, and Ferrite. The magnet 28 positions within recess 26 such that a North Pole N-28 remains within recess 26 and South Pole S-28 substantially flushes or aligns with first open end portion 22 to define a first magnetically attractive surface 30.

The first closed end portion 24 includes a post 32 that has an upper end 34 and a lower end 36. The upper end 32 defines a hinge portion 38 that that is preferably adapted to receive a hinged pin defined by the safety catch 16.

First body member has a flat top surface 40 and a fiat bottom surface 42 that define a height that, in the preferred embodiment is somewhat shorter than the length of the first body member 12. In this one preferred embodiment, the length and width of the first body member 12 are approximately equal to each other, although, it is understood the width and length may vary in other alternative embodiments. Post 32 has a height that is relatively greater than the height of the first body member 12 so as to allow catch 16 to be comfortably attached to upper end 34.

Referring to FIGS. 5 and 6, second body member 14 is bilaterally disposed along a central axis-B that is preferably adapted to be substantially aligned with the central transverse X-axis. Second body member 14 has a second open end portion 44 and a second closed end portion 46. The second open end portion 44 defines a cavity or recess 48 within the first body member 12 that is preferably adapted to accommodate a magnet 50. Magnet 50 is adhesively secured into recess 48, however, it is understood that magnet 50 can be secured within recess 48 using alternative techniques such as, for example, crimping or laser soldering. Magnet 50, in this one preferred embodiment, is preferably made of permanent magnetic material such as Sintered Neodymium Iron Boron (NdFeB) N50, however it is understood that magnet 50 can be also made of permanent magnetic materials such as, for example. Samarium cobalt, Alnico Ceramic, and Ferrite. The magnet 50 positions within recess 48 such that a South Pole S-50 remains within recess 48 and North Pole N-50 substantially flushes or aligns with second open end portion 44 to define a second magnetically attractive surface 52.

The second body-member 14 has a fiat top surface 54 and a flat bottom surface 56 that define a height that is somewhat less than the length defined by the second body member 14. In this one preferred embodiment, the length and width of the second body member 14 are approximately equal to each other, however, it is understood that the width and length may vary in other alternative embodiments.

In one embodiment, the second closed end portion 46 of the second body member 14 includes a bump 58 that protrudes from second closed end portion 46 and is preferably aligned along top surface 54, In this one embodiment, bump 58 is preferably of hemispherical shape, however, it is understood that the shape of bump 58 may vary in other alternative embodiments. Bump 58 is made by either being pressed out of the second closed end portion or permanently affixed to second closed end portion 46 using joining techniques such as, for example, welding or soldering.

Referring to FIGS. 7 arid 8, safety catch 16 includes a free end 60 and a hinged end 62. Safety catch 16 is bilaterally disposed along a central axis-C that is preferably adapted to be substantially aligned with the central transverse axis-X. The catch 16 has a top surface 64 and a bottom edge of the side panel 66 that define a width of the catch that is approximately half the width defined by the first body member 12 and second body member 14. The hinged end 62 includes a hinged ring 68 that is preferably adapted to be connected to hinge portion 38 (Refer FIGS. 2 and 3) of first body member 12 (Refer FIGS. 2 and 3).

The free end 60 includes a first protuberance 70 that preferably protrudes along an axis-P at a preferred angle of approximately 45 degrees from the central axis-C. The free end 70 is adapted to be either pushed down or pulled up with a finger to be grasped by at least two fingers of the user's hand. The free end 60 includes a second protuberance 72 that protrudes from the central axis-C. The second protuberance 72, in some embodiments, includes an indentation 74 that has a configuration to be engaged with bump 58 defined by second body member 14. First protuberance 70 and second protuberance 72 are approximately the same length, in the embodiment illustrated, although, it is understood that their length may vary in other alternative embodiments.

Top surface 64 is substantially flat and parallel to the central axis-C. Bottom surface 66 defines a pair of side panels 76 that preferably downwardly extend from central axis-C. The side panels 76 are substantially perpendicular the hinged end 62 and preferably decrease in their width up to free end 60. The side panels 76 are preferably adapted to prevent misalignment of the body members 12, 14 along the sideways from the central axis-X. The side panels stay by a closer fit to the second body members, so that a clicking sound is formed when the clasp is closed to indicate that it is closed.

Referring to FIG. 9, axis-A of first body member 12 (Refer FIGS. 3 and 4) and axis-B of second body member 14 (Refer FIGS. 5 and 6), in use, substantially align along the central transverse axis-X while connecting first body member 12 to second body member 14. The alignment of axes B and C along the central axis-X preferably allows South Pole S-28 of magnet 28 of first body member 12 to readily align and engage with North Pole N-50 magnet 50 of second body member 14. This allows first magnetically attractive surface 30 (Refer FIG. 3) to be connected with second magnetically attractive surface 52 to define a first locking arrangement of the clasp 10. In this position, first top surface 40 of first body member 12 (Refer FIG. 3) substantially aligns with second top surface 54 of second body member 14 (Refer FIG. 5). In this position, second bottom surface 42 of first body member 12 (Refer FIG. 3) substantially aligns with second bottom surface 56 of second body member 14 (Refer FIG. 3).
