The present invention relates to a magnetic clasp or a magnetic connecting device for jewelry or personal ornamental accessories such as necklaces, bracelets, or the like, jewelry accessories such as pendants and or centerpieces, and, in particular, to a magnetic clasp to be used to detachably fit or connect to the ends of the jewelry and/or jewelry accessory together.
For many years, jewelry designers have been looking for ways to allow flexibility in the look of their jewelry from charm bracelets to the traditional chain and pendant designs where users would thread various thin jewelry chains to a small ring from which a pendant hung. When the user wanted a different chain or pendant configuration it would be necessary to unthread and rethread a new pendant or new chain.
As for connecting devices that connect the ends of ornamental accessories such as a necklace, a pendant, or the like which is to be put to actual use in the form of an endless chain, there have been disclosed many ideas. A wide and highly used variety of connecting devices uses a construction in which a hook is engaged into a ring. Another variety is one in which a fitting device provided on both ends is engaged by means of a spring force. In wearing the above-described ornamental accessories, the handling for connection or engagement of split ends thereof should preferably be simple seeing that such connecting or engaging operation must be performed at the rear portion of the wearer's neck with his or her hands wound there around.
The fitting device made up of a hook and a ring is relatively simple in the connecting and disconnecting operation, but has a disadvantage in that the engagement is likely to be released or come out of engagement without the wearer's knowledge. Many pieces of jewelry or jewelry accessories have been lost due to this defect. The fitting device to be connected by means of a spring force, on the other hand, is relatively simple and handy, but it is accompanied with the trouble of having to release the spring force at the time of disengagement thereof. The spring release is often a tricky procedure which causes the wearer a loss of time and patience.
The system for jewelry accessories such as a pendant is most problematic with beaded jewelry. Often times the beads are too large for the majority of the pendants to be strung on. Most pendants will not accept multiple beaded strands or thick chains. Some pendant systems use a single small magnet, and the result is not sufficiently strong in order to accommodate the user's needs.
US patent application 2006/0096070 discloses a magnetic clasp for securing a piece of jewelry that includes a first connecting device having a first cylindrical magnet with a top surface. The first cylindrical magnet has a hollow cylindrical section located at the center of the first top surface. Additionally, a second connecting device has a second cylindrical magnet with a second top surface. The second cylindrical magnet has a cylindrical protruding member located at the center of the second top surface. The protruding section of the second connecting device fits into the hollow section of the first connecting device. The magnetic clasp locks when the first and second connecting devices are brought together allowing opposite magnetic poles to face each other. To unlock the magnetic clasp, the first and second connecting devices are rotatably turned allowing like poles to face each other.
A jewelry holder for holding a strand of jewelry may include a front ring member including a first embedded magnet and a back ring member including a second embedded magnet.
The front ring member may be detachably connected to the back ring member by cooperation of the first embedded magnet and the second embedded magnet.
The jewelry holder may include a center member, and the center member may be substantially T-shaped.
The center member may include a bottom section and the bottom section may include a decorative bottom surface to act as a pendant or centerpiece, and the center member may include a third magnet to cooperate with the first magnet and the second magnet.
The third magnet may be positioned within an aperture of the central member, and the center member may include a cover for the aperture of the center member.
The front ring member may include a front ring enclosure to enclose a plurality of rings to support at least one strand of jewelry, and the back ring member may include a back ring enclosure to enclose a plurality of rings to support at least one strand of jewelry.
The invention may be understood by reference to the following description taken in conjunction with the accompanying drawings, in which, like reference numerals identify like elements, and in which:
The present invention provides an advantage in the form of relief in function for users who may have arthritis or other disabilities to the hands or suffer from poor eyesight or eye hand coordination.
The clasp design of the present invention is adapted to accommodate multiple strands of beads and can accommodate many strands or few strands as desired. The clasp design of the present invention accommodates a larger, stronger magnet that is capable of holding the weight of multiple strands of jewelry which may include natural stone beads which may be too heavy for the prior art magnetic clasp.
The clasp design of the present invention incorporates a pin and hole system to secure the magnets from disconnecting and may not require the user any additional steps in order to take the clasp on and off.
The present invention does not require more complicated security systems which require the user to preformed additional steps.
The present invention incorporates magnets for easy installation and removal in order to change jewelry. The present invention incorporates increased flexibility in the look of the jewelry with respect to the option for multiple strands of beads/change, multiple sizes of beads/chains and multiple configurations of jewelry and jewelry accessories with use of the center member.
The present invention employs a pair of magnets which may cooperate in order to provide additional strength and safety. Additionally, the present invention employs a pin and hole system. This type of system does not require additional steps for the user.
The back surface 109 of the front ring member 101 may include a first and second male pin 111 to cooperate with a back surface 113 which may include a first and second female aperture 115. The first and second male pin 111 is inserted into the first and second female aperture 115 and held in place by the force of the magnetic fields generated by the first magnet 105 and the second magnet 107. The first and second male pin 111 and the first and second female aperture 115 prevent the front ring member 101 and the back ring member 103 from twisting and or shearing.
