## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates broadly to jewelry. More particularly, this invention relates to rings, necklaces, earrings, bracelets, and pendants having interchangeable and/or movable settings and attachable charms.
2. State of the Art
Jewelry is a very popular accessory, particularly among women and girls. Finger rings, bracelets and necklaces are the most popular jewelry items. Rings typically have one or more settings which carry precious or semi-precious stones. Bracelets and necklaces sometimes have hanging pendants or charms. Charm bracelets are unique in that one typically collects charms to be added to the bracelet over time. The charms usually commemorate some event, holiday, milestone, etc. Once added to the bracelet, however, charms generally are not easily removed. Eventually, the bracelet becomes full of charms and no more can be added.
SUMMARY OF THE INVENTION
It is therefore an object of the invention to provide a new and interesting item of jewelry.
It is another object of the invention to provide an item of jewelry which combines features of bracelets, rings, necklaces, earrings, and pendants.
It is a further object of the invention to provide an item of jewelry which is easily adaptable to suit the whim of the wearer.
In accord with these objects, which will be discussed in detail below, an item of jewelry according to the invention includes a removable or movable setting and a charm coupled to a short chain which is captured by the setting. The setting is removably or movably coupled to a ring, a pendant, a bracelet, an earring, or a necklace. According to one embodiment, the setting is removably threaded and the item of jewelry includes a threaded post which mates with the setting. In this embodiment the charms are coupled to washers or loops which fit over the threaded post. The presently preferred washers have ears so that multiple charms can be attached to the post with the washers lying flat relative to each other. In another embodiment, a safety catch is provided to prevent the setting from accidentally disengaging from the threaded post. The threaded post may be part of a ring, a pendant, a bracelet, an earring, or a necklace. The removable setting is preferably interchangeable with other settings. The interchangeable charms are preferably provided in a wide range of designs, including, but not limited to holiday themes, religious themes, astrological signs, varsity letters, graduation year, wedding themes, commercial characters such as Disney characters, TV characters, messages such as “I Love You”, etc. The interchangeable settings may include different color stones to match different color clothing, birth stones, etc., or may provide different motifs such as initials.
According to a second embodiment, the removable setting is cylindrical with peripheral bayonet lock slots. The item of jewelry includes a slotted cylinder with a pair of interior bosses which are arranged to engage the bayonet lock slots on the setting. Charms are provided with ball (or other engagement shape) and chain. The balls are arranged inside the slotted cylinder with the chains extending through the slots. The balls and slots are dimensioned to prevent passage of the balls through the slots. After the charms are so arranged, the setting is attached. Preferably, a spring is arranged between the setting and the slotted cylinder.
According to a third embodiment which is similar to the second embodiment, the setting is not removable but is simply movable. In this embodiment, the setting is provided with a post and the item of jewelry is provided with a cylinder which receives the post. The cylinder is provided with an interior groove and the post is provided with an orthogonal boss which engages the groove. A spring is arranged around the cylinder and biases the setting away from the item of jewelry. Rotating the setting in one direction unlocks the setting and permits the setting to move up relative to the item of jewelry, making room for the balls of the charms to be placed in the slots. The setting may be moved against the spring to close over the slots capturing the balls of the charms. Rotation of the setting in the opposite direction locks the setting relative to the item of jewelry.
According to a fourth embodiment which is similar to the third embodiment, the setting post is actually a cylinder and the spring is contained therein so that it is not visible. The fourth embodiment operates in the same manner as the third embodiment.
According to a fifth embodiment, the setting is removably coupled to the jewelry via one or more magnets.
Additional objects and advantages of the invention will become apparent to those skilled in the art upon reference to the detailed description taken in conjunction with the provided figures.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Turning now to FIG. 1, a finger ring 10 according to the invention includes a closed loop 12 which is dimensioned to fit comfortably over the wearer's finger, a radially outward extending threaded post 14, and a setting 16 having internal threads 18. The setting 16 preferably receives and holds a precious or semi-precious stone 19. As used herein, the term “stone” means something held by a setting for display. It is not necessarily a precious or semi-precious gemstone or even a simulation of a gemstone, as it may be a precious or other metal providing a decoration or motif, glass, crystal, etc. If desired, a safety latch (not shown) can be provided to latch the setting to the ring and/or stem.
From the foregoing, those skilled in the art will appreciate that the setting 16 is removable from and attachable to the post 14. Thus, a plurality of settings holding different stones may be interchangeably attached to the post 14 resulting in different style rings. The stones in the interchangeable settings may include different color stones to match different color clothing, birth stones, etc., or a metal “stone” with a motif or decoration. Settings which hold multiple stones may also be used. The settings are preferably made from a precious metal such as silver, gold, or platinum. However, in order to provide a ring affordable by teenage or younger girls, the settings can be made of “white metal” and the stones can be made of inexpensive materials including metal, glass or plastic.
Referring now to FIG. 2, a charm 20 according to the invention includes a loop 22 coupled by one or more chain links or loops 24 to a charm element 26. According to the invention, the charms are preferably provided in a wide range of designs, including, but not limited to holiday themes, religious themes, astrological signs, varsity letters, graduation year, wedding themes, commercial characters such as Disney characters, TV characters, messages such as “I Love You”, etc.
Turning now to FIG. 3 and with reference to FIGS. 1 and 2, according to the methods of the invention, the setting 16 is separated from the post 14 as shown in FIG. 1. The loop 22 of the charm 20 is placed over the post 14 and the setting is 16 is reattached to the post as shown in FIG. 3. The chain link(s) 24 form(s) a chain which is preferably short enough so that when it is attached to the post, the charm does not hang between the wearer's fingers. According to the preferred methods of the invention, up to three or more charms may be attached to the ring at any one time. FIG. 4 shows a ring with two charms 36 and 46 each coupled to a chain link 34, 44 coupled to a loop 32, 42. The loops 32, 42 are positioned over the post as shown with the setting on top. It will be appreciated that in order to accommodate multiple charms, the post may need to be elongated beyond the depth of the internal threads in the setting. If this is the case, blank spacer loops (i.e. without a charm) may be provided to cover exposed portions of the stem when fewer than the maximum number of charms are attached.
FIG. 5 shows an alternate embodiment of a charm 120. The charm includes a loop 122 coupled by a link 124 to a charm element 126. According to this embodiment, the loop 122 has an ear 123 through which the link 124 extends. This ear allows the stacking of several loops on a post as shown for example in FIG. 6 (with the charm elements and links removed for clarity). There it can be seen that three loops having ears 123, 123′, and 123′′ are placed over post 14 with the ears circumferentially spaced apart. This arrangement allows the loops 122 to lie flat without the links 124 interfering.
FIGS. 7 and 8 schematically illustrate a pendant 200 according to the invention, The pendant includes a neck chain 202 and a pendant element 204 attached to the chain 202 by a link or loop 206. According to this embodiment, the pendant element 204 has a threaded post 214 similar to the post 14 described in FIG. 1. A setting 16 like the setting described in FIG. 1 is adapted to threadably engage the post 214. Charms (20 in FIG. 2 or 120 in FIG. 5) can be placed on the post 214 and secured by attaching the setting 16.
FIG. 9 shows another example of neckwear according to the invention. A necklace 300 according to the invention includes a rigid or semi rigid neck ring 302 supporting three threaded posts 314, 314′, and 314′′. Three settings 16 (FIG. 10) are provided and charms are attached to the posts as described above. As with the ring and pendant embodiments, the setting 16 can be interchanged with other settings having different aesthetic appeal, complimenting the charms, individualized for a birthstone, zodiac symbol, monogram, etc. In other words, jewelry according to the invention (e.g. rings, neckwear, bracelets and earrings) can be assembled as a system of settings, charms and jewelry items to which the settings and charms can be mixed and matched.
FIGS. 11 and 12 illustrate a second embodiment of a ring and charm assembly according to the invention. The assembly 400 includes a closed loop (ring) 412 which is dimensioned to fit comfortably over the wearer's finger. A substantially cylindrical “basket” 414 is mounted radially relative to the loop 412, The basket has a plurality of circumferential slots 415 and a pair of diametrically opposed interior bosses 417 (FIG. 12). A removable setting 416 is provided with a lower cylinder 407 having an external diameter smaller than the internal diameter of the basket 414. The cylinder 407 has a pair of diametrically opposed bayonet slots 418 which are dimensioned to receive respective bosses 417 on the basket 414 and a spring 419 having a diameter smaller than the interior diameter of the cylinder 407 is also provided. A charm 420 includes a mounting ball 422 coupled by one or more links 424 to a charm element 426. The mounting ball 422 has a diameter larger than the width of the slots 415 and the link 424 immediately connected to the ball 422 has a dimension which is narrower than the width of the slots 415. From the foregoing, those skilled in the art will appreciate that the ring and charm(s) are assembled by placing the ball(s) 422 in slot(s) 415, placing the spring 419 into the basket 414, placing the cylinder 407 over the spring 419, pressing the setting 416 into the basket with the opening to the bayonet slots 418 receiving the bosses 417, then turning the setting 416 until the bayonet slots 418 fully engage the bosses 417. When the setting 416 is released, the spring 419 will force the setting up slightly, thereby engaging the bosses in the vertical ends of the slots 418. In order to remove the setting, it must be pushed against the spring and turned in the opposite direction. So long as the setting is captured by the bosses, the ends of the slots 415 are covered by the setting and the charm(s) 420 are securely attached to the ring. It will also be appreciated that this arrangement of a slotted basket spring and bayonet lock can be applied to pendants and necklaces as well.
FIGS. 13 through 18 illustrate a third embodiment of a ring assembly 500 according to the invention. The assembly includes a closed loop (ring) 512 with a frustoconical basket 514 mounted thereon. The basket 514 is provided with a plurality of slots 515 like the slots 415 in the third embodiment and they are dimensioned to capture charms of the type 420 (FIG. 11). A frustoconical setting 516 has a lower lip 516a which has a slightly larger diameter than the top of the basket 514. The setting 516 has an upper decorative stone 516b and a lower downward extending stem 507. A small cylinder 518 is provided with a radial boss 518a and a spring 519 is also provided. The bottom of the basket 514 has a keyhole 514a as shown in FIG. 14. A first disk 514b with a similar keyhole 514c is located inside the basket spaced up from the bottom of the basket. A second disk 514d having a circular hole 514e is located inside the basket 514 between the first disk 54b and the slots 515. The keyholes 514a and 514c are dimensioned to allow the passage of the cylinder 518 and boss 518a. The circular hole 514e is dimensioned to allow the passage of the cylinder 518 but not the boss 518a. The stem 507 is dimensioned to fit through all of the holes 514a, 514c, 514e an into the cylinder 518.
The ring assembly 500 is put together by placing the spring 519 into the basket 514 where it rests upon the disk 514d. The stem 507 of the setting 516 is then inserted through the spring and through the hole 514e. The setting is pressed down against the spring until the stem 507 extends through the hole 514c and into the hole 514a. The length of the stem is preferably long enough to lie flush with the bottom of the basket but not pass through it. The cylinder 518 with its boss 518a is then pressed through the keyhole 514a and onto the bottom of the stem 507. The cylinder is secured to the stem by any one or more of: force fitting, welding, gluing, etc. With the cylinder 518 securely coupled to the stem 507 of the setting, the setting can be released and, if the boss 518a is aligned with the keyway in the hole 514c, the spring 519 will lift the setting up to the position shown in FIG. 17 with the boss abutting the underside of the disk 514d. Pushing the setting down with the boss aligned with the keyway in the hole 514c will locate the boss beneath the disk 514b as shown in FIG. 18. Turning the setting so that the boss is no longer aligned with the keyway will trap the boss beneath the disk 514b. In this position, the lip 516a of the setting overlies the top of the basket 514.
It will be appreciated that in the embodiment pictured and described, the setting is free to rotate 360°. According to a preferred realization of this embodiment, rotation of the setting is limited to about 90° from an open to closed position. This is accomplished by placing rotation limiting structures (not shown) on the disks 514b and 514d. 
FIG. 19 shows a fourth embodiment of a ring assembly according to the invention. The assembly includes a closed loop (ring) 612 and a basket 614 having slots 615. The setting 616 has a centrally located downward extending hollow post or cylinder 618 with a radial opening 618a dimensioned to receive a radial boss 618b. The basket 614 is provided with a central cylinder 614a which has a bayonet slot 614b. The bayonet slot is preferably L-shaped, J-shaped, or boomerang shaped. A spring 619 is provided and is dimensioned to fit inside the post 618. The cylinder 614a, the hollow post 618, and the boss 618b are dimensioned such that the post 618 fits inside the cylinder 614a and the boss 618b extends into the slot 614b. 
The assembly 600 is put together inserting the spring 619 into the post 618, inserting the post and spring into the cylinder 614a, and inserting the boss 618b through the slot 614b into the radial hole 618a in the post 618. An alternate assembly method is to continue the slot 614b to the top of the cylinder 614a so that the post 618 with the boss 618a can be inserted into the cylinder and slot and then sealing off the top of the slot by welding or the like. Still another assembly method is to pull the boss out of the post into the slot after it is in the cylinder.
When the assembly is put together as shown in FIG. 20, the setting 616 is biased upward and can be turned with the boss riding in the bayonet slot to an upward open position (shown) or to a downward closed position (not shown). This embodiment uses the same type of charms (420 in FIG. 11) as described above.
FIG. 21 shows a ring 700 according to the invention where the setting 716 has a magnetic post 718 (or a magnet attached to the post) and/or a magnet is disposed inside the basket 714.
From the foregoing, it will be appreciated that the rings according to the invention all define a finger axis at the center of the closed loop and a setting axis which is perpendicular to the finger axis. Charms are attached to the rings (captured by the settings) on an axis substantially perpendicular to the setting access (not accounting for the flexibility of the link(s) coupled to the charms).
FIG. 22 shows another pendant according to the invention having a setting 816 which is movable or removable and one or more interchangeable charms 820.
FIG. 23 shows an earring 900 according to the invention having a setting 916 which is movable or removable and one or more interchangeable charms 920.
FIG. 24 illustrates a bracelet 1000 according to the invention having one or more settings 1016 which are movable or removable and one or more interchangeable charms 1020 associated with each setting.
There have been described and illustrated herein several embodiments of an item of jewelry and methods of assembling it. While particular embodiments of the invention have been described, it is not intended that the invention be limited thereto, as it is intended that the invention be as broad in scope as the art will allow and that the specification be read likewise. Thus, while a ring with up to six charms has been disclosed, the maximum number of charms could be greater or fewer. Also while charms have been shown with a chain or chain link connecting them to an end which is captured by a charm capturing fixture (e.g. threaded post or slot in a basket), the charms could be coupled by any flexible or rigid member to an end which is captured by a charm capturing fixture. Moreover, while the captured ends of charms have been illustrated and described as “balls”, it will be appreciated that other shapes which perform the same function could be used. It will therefore be appreciated by those skilled in the art that yet other modifications could be made to the provided invention without deviating from its spirit and scope as claimed.
