ARTICLES OF JEWELRY WITH PROVISION FOR MAGNETIC INTERACTION
An article of jewelry, e.g. necklace, bracelet or the like, comprising a flexible strand and one or more ornaments shaped, configured and dimensioned to be slidably retainable on the strand; one or more spaced apart magnetic components associated with (e.g. embedded) inside the strand; and a magnetic insert embedded in at least one of the ornament or ornaments which magnetic insert is attractable to the magnet components, whereby the one or more ornaments can be releasably retained on the strand by the force of magnetic attraction. Some examples of the strand can also have no ornaments and be stackable together using the force of magnetic attraction, and also a magnetic connector assembly comprising a first part coupled to a first end of the strand, and a second part coupled to a second end of the strand, each part having a magnetic component attractive to each other, the first and second parts being adapted to releasably connect together to form the strand into an endless loop.
This invention relates to articles of jewelry, and more particularly, to articles to jewelry having magnetic elements.
BACKGROUND OF THE INVENTIONArticles of jewelry are known comprising multiple precious or semi-precious stones, beads, charms or other ornamental objects strung on a strand, such as a necklace, bracelet or anklet chain. In some instances, the placement of the strung objects is not secure and there is a risk of damage to the objects through contact with neighbouring strung objects. Furthermore, in some jewelry, there is no provision for keeping a strung object in a selected position on the strand, with the result that the wearer is constantly in need of moving the object, such as a pendant, back to the desired location.
Different approaches have been developed to limit the movement of objects along a strand of jewelry, including the use of clasps, glue, and knots, such as knots used in a string of pearls to keep the pearls in place on the strand.
The use of clasps or keepers to keep various beads in place on a piece of strand jewelry is documented in U.S. Pat. No. 7,007,507 to Enevoldsen (owned by Pandora Jewelry LLC). This patent discloses bracelet and necklace systems that employ spacers and clips to prevent the bunching of strung jewelry beads, bangles and baubles.
United States Patent Publication No. 2007/0084241 to Kretchmer et al. teaches a jewelry article comprising at least two magnetic jewelry forming components which repulse each other with a magnetic strength that can be overcome by a person's hand strength such that the components can be placed in different positions relative to each other. The disclosed embodiments require the magnetic components to be positioned on a rigid rod. Without the rigid rod, neighbouring magnetic elements would tend to flip over to orient north and south poles together.
U.S. Pat. No. 8,490,429 B2 to Huynh discloses an article of jewelry including a plurality of precious or semi-precious objects movably positioned along a pliable strand. Each object includes a magnetic insert extending between opposing surfaces. The insert is formed from two magnets separated by a magnetic stabilizer and aligned so that the opposing ends of the magnetic inserts of adjacent objects on the strand create repulsive forces that function to repulse adjacent objects on the strand to keep the objects apart.
U.S. Pat. No. 2,654,929 to Feibelman teaches a separable magnetic connector for bracelets and the like which include mechanical connector elements.
U.S. Pat. No. 3,177,546 A to Bey discloses a magnetic connector assembly for connecting objects such as a key or a jewelry clasp, and which allows the objects to be pulled apart.
U.S. Pat. No. 6,962,063 B1 to Pearl discloses an arrangement of stringed magnetic and non-magnetic beads worn as a necklace or bracelet in loops that are formed by the contact of the magnetic beads.
U.S. Pat. No. 5,195,335 to Hart teaches a necklace or the like comprised of discrete beads and selectively positioned magnetized pieces. The magnetized pieces can be placed into contact with each other using the force of magnetic attraction to allow the user to wear the necklace in one of a number of different configurations.
While prior art approaches may be satisfactory, the present invention is intended to provide new articles of jewelry that are easy to use and can be easily customized to create unique and multiple looks.
SUMMARY OF INVENTIONAccording to one aspect, the invention provides an article of jewelry comprising a strand, which may be flexible, for encircling a body part of a wearer, and a magnetic component associated with the strand, e.g. releasably or fixedly attached to the strand, for use in connecting the strand to another article of jewelry comprising its own magnetic component. The other article of jewelry may be another strand, as in the case of stacking bracelets or necklaces, for example, or one or more ornaments to be retained on the strand.
According to another aspect, the invention provides a a magnetic connector assembly comprising a first part coupled to a first end of a flexible strand, and a second part coupled to a second end of the flexible strand, each part having a magnetic component for use in releasably connecting the two ends of the strand together to form the strand into an endless loop around a wearer's neck, wrist, ankle, etc.
The magnetic component may be embedded wholly inside the strand or retained externally on the strand. When a plurality of magnetic components are employed, they may be arranged in a spaced apart relationship. Ornaments may be shaped, configured and dimensioned to be slidably retainable on the strand, and comprise a magnetic component attractive to the magnetic component of the strand, whereby the ornament can be maintained in a selected position on the strand.
The magnetic component of the strand and/or ornament may be a magnet or a ferromagnetic material attractive to a magnet. In the case of ornaments, the ornament may define a bore or a hook dimensioned and shaped to slidably receive the strand therethrough and the magnetic component may be adjacent to the bore or hook opening of the hook.
The ornament may also comprise two halves which together define a bore, each half incorporating a magnetic component attractive to each other for connecting the two halves together to form a whole, whereby the ornament can be attached to the strand when it is formed as an endless loop by prying the two halves apart and connecting them together around the strand using the force of magnetic attraction.
Regarding the connector assembly, the first part may comprise first and second members, the first member being coupled to the first end of the strand and having a diameter smaller than the diameter of the bore of the ornament such that the ornament can be slid over the first member onto the strand, the second member being releasably attachable to the first member and having a diameter greater than the diameter of the bore, whereby the second member can act as a stop to prevent the ornament from sliding off the first end of the strand. The first member may have an externally threaded shaft, and the second member may have a complementary internally threaded bore whereby the second member can be screwed onto the first member. The second part may have an outer diameter that is greater than the diameter of the bore of the ornament to prevent the ornament from sliding off the strand at the second end. The first and second parts may also have a mutually complementary, interlocking shape, and may be configured to be movable between unlocked and locked positions, whereby in the locked position, the parts cannot be pulled axially apart or rotated axially relative to one another. For example, the first part may have a longitudinally extending tongue and groove, and the second part may have a complementary longitudinally extending groove and a tongue that mates with the tongue and groove of the first part when the first and second parts are moved transversely together.
The invention allows users to removably affix one or more decorative elements (e.g. ornaments) to a strand in one or more positions to create a variety of looks. When positioned in a spaced apart relationship, the ornaments can avoid getting damaged by rubbing together. The simplified connector assembly, e.g. clasp or closure mechanism, allows the user to easily put on and remove the strand and to replace, remove, and/or add ornaments. Bracelets, necklaces, anklets and the like may be stacked together to create thicker articles of jewelry. Still other embodiments of the invention can employ magnetic components providing magnetic therapy and health benefits to the wearer.
The invention may be better understood with reference to the following description of various embodiments and drawings in which:
In this patent application, wearable jewelry including bracelets, necklaces, anklets, waist chains and other similar products may also be called “stranded jewelry”. Chains, cables, strands, strings, chords and other similar items may also be called “strands”. Magnetic components means components that are magnets or which can be magnetically charged to form a magnetic field, e.g. components made of ferromagnetic materials such iron, chrome, and the like.
Magnetic components can pertain to the strand, and such will may herein also be called “attractors.” Ornaments such as beads, baubles, charms and the like, incorporating magnetic components may herein also be called “attractor ornaments.”

As best shown in
While in this embodiment, the internal magnetic attractors 40 are permanently fixed within the strand, in other embodiments, they can be made to move inside the strand, such as would be desirable, for example, when there is no need to mount ornaments in a spaced-apart relationship.
Magnetic connector assemblies according to the invention can be varied in a number of ways including by changing their shapes. For example,
The ornament 50 described above can be varied in a number of ways. For example, the ornament can be made in two parts—see ornament 150 of
Referring now to
Bracelets and other strand jewelry can be made to incorporate internal attractors having opposite polarities so that the strand jewelry can be stacked together and held together by magnetic force. The internal attractors may also extend the full length of the strand. For example, see the bangles 630 having internally embedded magnetic attractors 640 in
Clearly, other variations to the aforedescribed embodiments are possible without departing from the scope of the invention as claimed below. There can be any number of external magnetic attractors 42, 43, which can come in various shapes and sizes and can be mounted in different locations on the strand. The external magnetic attractors 42, 43 can also be made to move freely or be secured on the strand 30 by magnetic attraction to an internal magnetic attractor 40, in the same way that magnetic ornaments (e.g. ornament 50) can remain secured. Likewise, there can be any number of internal magnetic attractors 40, which can also come in various shapes and sizes (to match the surrounding strand) and can move freely and/or be spaced apart at differing intervals.
The tranverse cross-sectional shape of the strand can be varied, as can be the length and diameter or thickness of the strand. The shape, size, pattern, ornamentation and configuration of the ornament can also be varied within functional limits, as will be apparent to the person skilled in the art.
As depicted in
These and other variations to the embodiments described above are within the scope of the invention herein described and claimed.
