DETAILED DESCRIPTION OF THE INVENTION

[0024] FIGS. 1-3 illustrate an example of a finger ring 100 of the present application. The ring 100 is formed from a plurality of separable segments 102 that are secured together using magnets 104 having a high magnetic strength of at least 0.4 lb pull strength. Each magnet 104 may be neodymium-based magnetic compound (NdFeB) (commonly referred to as Neodymium) and/or an iron nitride magnetic compound (Fe.sub.16N.sub.2). The segments 102 may be made of a traditional soft metal, such as gold, silver, or titanium, or a non-metal material such as silicone, plastic, precious stones, or ceramic. Although the embodiments illustrated herein are rings, the design may be utilized in a bracelet, necklace, chain-link, watch band, sleeve, head band, or other item of jewelry or accessory.

[0025] As shown in FIG. 1, the ring 100 includes first through four segments 102A-102D. Seen best in FIG. 2, each segment 102 has an arcuate shaped defined by an inner surface 106 and an outer surface 108 between first and second end surfaces 110, 112. First and second magnets 104-1, 104-2 of opposing forces are embedded at the juncture of the end surface 110, 112 and the inner surface 106 at a mid-point along the height of the segment 102. The segments 102 join together to form a continuous loop.

[0026] In some embodiments, the segments 102A-102D have identical shapes and sizes. In another embodiment 200 shown in FIG. 4, the segments 202 of the ring 200 include various sizes and lengths. The segments 302 may have any shape, such as the round pearl segments 302 of the embodiment of the ring 300 illustrated in FIG. 5. Segments 102 can be interchanged and mixed based on size, shape, color, pattern, design, texture, surface engraving, or material according to user preference. Segments 102 can also be added or removed from the ring 100 over time as needed to adjust for the wearer's change in ring size.

[0027] Referring back to FIGS. 1-3, each of the adjacent end surfaces 110, 112 of neighboring segments 102 includes magnets 104-1, 104-2 positioned to securely attach to one another. One end surface 110/112 includes a positively-aligned magnet and the other end surface 112/110 includes a negatively-aligned magnet. The use of neodymium and/or an iron nitride magnetic compound minimizes the contact surface area between adjacent segments 102 while maintaining loop integrity, allowing for a smooth and seamless appearance. While other designs integrate clasps, links, or other mechanical structures to increase the surface area between magnetic sites, therefore increasing the magnetic attraction, the ring 100 of the present application minimizes the contact area while maintaining loop integrity. The use of neodymium and/or an iron nitride magnetic compound enables the jewelry 100 to maintain its connected state using magnetic forces without relying on a large surface area or cumbersome mechanical structures as well. The use of high strength magnets also allows the ring 100 to easily break apart with sufficient force to overcome the magnetic attraction. This ability to break apart eliminates the chance of degloving and other similar injuries.

[0028] In some embodiments, the magnet 104 is embedded within the metallic segment 102 and may be coplanar with or below the surrounding external surfaces. In the embodiment illustrated in FIGS. 1-3, the magnets 104 are positioned along the inner surfaces 106 so that the overall outer surface of the ring 100 appears continuous and seamless. In other embodiments, the magnets 104 may be centered within each end surface 110, 112. The use of a high strength magnet 104 allows for the secured attachment of the segments 102 without the need for an additional mechanical structure to establish the connection. By minimizing the components of the design, the outer surface of the ring 100 has a continuous, seamless appearance. In some embodiments, mechanical means may be incorporated into the end surfaces 110, 112 while maintaining the appearance of the seamless, continuous ring 100. For example, coordinating magnets 104 may be positioned on corresponding groove and protrusion structures centered within end surfaces 102C, 102D of neighboring segments 102.

[0029] In another example embodiment of the ring 400 illustrated in FIGS. 6 and 7, the ring 400 includes an inner base 414 comprised of a pliable material onto which the metallic or non-pliable segments 402 are positioned. As in the previous embodiments 100-300, the segments 402 are secured together with magnets 404. The inner base 414 is a continuous ring with an recessed surface 416 extending along the circumference of the ring 400 between first and second rims 418, 420. The segments 402 fit securely along the recessed surface 416.

[0030] The inner base 414 of ring 400 may be comprised of a silicone or other durable, pliable material. Use of a pliable material provides a more comfortable ring to the wearer. The lightweight, flexible material also breaks under extreme pressure, so should the ring 400 become entangled in extreme forces and be forcibly removed from the wearer's finger, the inner band 414 breaks and the segments 402 separate as the magnetic strength is overcome, thereby avoiding ring avulsion or other serious injury.

[0031] In other embodiments, the first and second rims 418, 420 may be only slightly raised relative to the recessed surface 416. In still further embodiments, the width of the first and second rims 418, 420 may be slight compared to the width of the segments such that the overall appearance of the ring 400 is simply the metallic or non-pliable segments 402.

[0032] It should be noted that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages.
