RELATED APPLICATIONS
This divisional patent application includes the contents of provisional patent application Ser. No. 61/713,860, filed Oct. 15, 2012 and patent application Ser. No. 13/875,989, filed May 2, 2013 the contents of both of which are incorporated herein.


BACKGROUND OF THE INVENTION
The present invention relates to a jewelry article, and in particular to a jewelry article that permits the exchange of portions of the jewelry piece in order to create a variety of different looks for the piece of jewelry. The piece of jewelry can be a ring, a necklace, a pendent, a bracelet or any other type jewelry in which portions of the jewelry can be changed through attachment and detachment. The present invention also refers to a jewelry article that permit supplemental pieces to be added to a basic piece, thus changing the appearance of the jewelry piece instantaneously.
All types of jewelry are known in the prior art. Sculptured pieces are known in the prior art in the form of three dimensional pieces. Jewelry pieces can be made of all types of metal or may be carved from natural occurring material such as precious stones, semi-precious stones, shells or synthetic material. Another form of jewelry article comprises ring-shaped articles to be worn on fingers, around the neck, on arms and around the hand joint. The term ring-shaped includes also shapes that are not circular but includes any shape that has a round silhouette including octagons.
In the world of jewelry, often dictated by beauty and fashion, there is always the need for new designs; for example, the way a necklace is designed often depends on certain technical functions such as the closure or how to connect a centerpiece of a necklace; for example, a pendent to a chain. In addition, oftentimes, especially in the case of finger rings, there may be the problem of fitting a ring over the knuckles of the person's finger which makes it hard to slide the ring into place when the knuckles are big or swollen. The jewelry article of the present invention not only fulfills such a need for fitting the jewelry, but also allows for changing the appearance of the jewelry piece by exchanging portions of the jewelry piece with inserts of different shape and/or color, but also, when the present invention is implemented in a finger ring, a bangle or a necklace, makes the fitting onto the respective finger, wrist or neck extremely easy. The insert can be metal or gem stones, but also any other material fitting the design and desire. Thus, the jewelry piece of the present invention allows for endless design possibilities, while being unique and ultimately very practical.
It would therefore be desirable and advantageous to provide a novel jewelry article of new and unknown design possibilities, improved ease, versatility and beauty of the object due to the enormous number of variations that are possible with the new structural elements of the jewelry.
SUMMARY OF THE INVENTION
According to one aspect of the present invention, the article is embodied in a jewelry article including two member arms each having opposing ends and being pivotably connected to one another at respective first ends of said ends, such that in a first position, the member arms, at respective second ends opposite the first ends, are in an open position defining a space between the arms, while in a second position, the second ends of both arms are moved towards each other into a closed position, the article further includes an insert for insertion into the space between the two arms when the arms are in an open position and for connecting the insert to each of the arms when in a closed position and means for secure attachment of the insert to the arms when the arms are in the closed position.
According to another aspect of the present invention, the article includes two member arms pivotably connected at one of their ends, with the ends opposite of the pivoted ends provided with a snap closure. Upon closure, the two arms form a ring-shaped article able to hold a number of additional decorative pieces. Alternatively, an insert is placed between the member arms. Either one of these embodiments are wearable as a necklace or a bracelet. The arms of the rings-shaped article have a circular cross section but can have any cross sectional shape suitable for the purpose. Additional pieces to be added to the ring-shaped article are provided with rings or circular shapes for sliding onto the ring-shaped article and being loosely held by the ring-shaped article. The additional pieces can be purely ornamental or they can represent a chain to be worn around the neck by a wearer. Endless variations are possible for wearable jewelry such as necklaces, bracelets, earrings, rings and similar articles.
The pivoting action of the two member arms is accomplished by providing a joint connection at each of their first ends by which the member arms are movable at the first end such that the second end moves from an open position to a closed position. The joint connection may be a hinge but can be any other pivotable joint connection. Joint connections are known to those that are working in the art and are not further described here except to note there are variations that are known for such pivotable joints.
In another embodiment of this invention, a spring assist is provided at the joint connection to assist in the closing and securing of the jewelry item from the open to the closed position.
In another aspect of the invention, for attachment of the insert between the two arm members, each of the second ends of the respective member arms can be provided with recessed magnets which engage with corresponding recessed magnets placed in the insert upon moving the two member arms into the closed position.
In a further aspect of the invention, each end of the respective member where the insert is placed, can be provided with projecting connecting members that engage with corresponding openings in the insert when closing the member arms. The projecting members can also be configured as pins.
In a variation of that attachment mode, the opening in the insert can be tapered along its extension so that when rotating the insert onto the post or pin, the insert becomes locked into place.
As a further means of attachment, at least one of the posts can be threaded for engagement with a corresponding thread in at least one of the openings of the insert.
The insert attached to the respective members can be configured such that its shape, especially a bottom wall is curved so that it corresponds to the shape of a finger, an arm or other body part at the location where the insert will rest on the body part.
The modes of attachment of the insert can vary, for example, the insert can have a bore-through opening and the pins on each of the members may be configured as posts that have recesses for placing magnets therein. Each of the posts with the magnets slide into the bore-through opening of the insert connecting with the corresponding post from the other side via the magnets. This mode of attachment works particularly well with an insert that is bead-shaped.
In another embodiment, the attachment mode is reversed from the foregoing in that the insert is provided with a pin or post at each of its ends and the member arms are provided with recesses, such that, when placing the insert between the two members the pins or posts slide into the respective recess of each member.
The insert itself can of course be shaped in a multitude of different shapes and designs to accommodate the taste and desire of the designer or the wearer, so long as it is provided with means for connecting to the member arms.
In one embodiment, the insert is bejeweled with jewels. In another embodiment, the insert is fashioned from one or more metals. The insert can also be a pearl, pearls or a bead or several beads.
According to one embodiment of the invention, the article is a finger ring wherein the member arms form the two shanks of the ring and are pivotably joined at one end of a circular or approximately circular shape with the insert inserted between the uppermost ends of the two shanks. The shanks are connected at one end by a joint that permits a pivoting motion of the two shanks whereby the two member arms open and close to facilitate an exchange of the insert at the end opposite the joint. The joint which allows the pivoting motion at one end of the two shanks can be a hinge or any other pivotable connection, and may include a spring assist in the hinge.
According to another embodiment of the present invention, the article is configured as a bangle, which functions in the same manner as the finger ring, whereby the two members are pivotably joined together at one of their ends for moving the two arms into an open or closed position with the insert therebetween.
In another embodiment of the present invention, the members of the article consist of two semicircular rings that can be connected by means of magnets placed in recesses at each end of the semicircles. An insert, also provided with recessed magnets is lodged between the semicircular rings.
In a variation of that embodiment, instead of the members being semicircular, they have a rectangular shape. In any case, the insert can be as varied as one's imagination and strength of the magnets holding the inserts in place.
The magnetic connecting means can take on various embodiments. In one of the embodiments, magnets are received in recesses provided in each of the members, preferably in the complementary portion of each of the members. The magnets can also be covering the entire surface of the complementary portion of each arm in case the member has a rectangular shape.

The ends of each shank or arm 3, 4 can bear jewels 10 as seen in FIG. 6 which can be matched to the jewels 10 of the insert 5.
In FIG. 3, 4, shanks 3, 4 are seen in open position with each post 6 provided with a magnet 7 indicated by broken lines. In FIG. 14 arms or shanks of a bracelet 3, 4 are seen in closed position without the insert 5. The magnets 7 are seen connected in FIG. 1. FIG. 7 shows a view along line B-B with the insert being a bead having a bore-through. As is seen in FIG. 7, a bead 5 has an internal recess which is shown here as a bore-through, but need not be an entire bore-through but can be just recesses. The recess can also have a thread 9′ with a corresponding thread 9 at a post 6. In a variation of the posts 6 engaging with the insert 5, FIG. 9 shows a small bead as an insert at least one of the posts is provided with a thread 9′′ for threadedly connecting with a corresponding thread 9a in the jewelry article (See FIG. 10). Another possibility is to have both a magnetic and a threaded connection with the insert 5, with at least one thread at one of the posts 6. In FIG. 12 the posts are showing to some extent, the bead will be however locked in by the threaded connection.
It should be noted that there is no limit as to the decoration of both the ends of shanks 3, 4 bearing the posts 6 or the insert 5.
FIG. 13 shows another embodiment of the article where the two member arms are formed into a bangle 10. The pivotable joint 2 allows the two member arms to be in the open position. In that position, additional ornamental pieces can be added; for example, rings or so-called charms, pieces that are provided with rings for sliding onto the article.
