The clasp may also include a mechanical lock. The magnetic attraction of the magnetic components assists in engaging and maintaining the mechanical lock.
Description
- This application claims priority in U.S. provisional application serial No. 60/389,358, filed on Jun. 15, 2002.
- The present invention relates to magnetic clasps and, more particularly, relates to a concealed secure magnetic clasp for jewelry.
- Jewelry is generally very costly. Many types of jewelry, such as bracelets and necklaces, include fastening devices and/or closures that affix one end of an open loop to another to close the loop. The security and reliability of such fastening devices and/or closures are important factors in the value of the jewelry. Nearly all solutions in the jewelry industry involve solid mechanical clasps, clips, loops, snaps, buckles, threaded assemblies, and the like. For a variety of reasons, only a very few effect fastening and closure through the use of magnetic attraction.
- Known magnetic clasp assemblies in the jewelry industry involve a variety of self-aligning, butted, conical, round, square, rectangular, and tubular designs. Some are mechanically simple configurations while others are mechanically complex configurations. Magnetic clasp assemblies are also used in applications other than jewelry, but the jewelry industry and its market places special importance upon attributes such as appearance that are not necessarily significant in those other fields. All prior art configurations, whether jewelry-related or not, involve considerable compromises.
- One problem with existing magnetic jewelry clasps is their appearance. The appearance of the magnetic fixture may detract from the appearance of the item of jewelry. The appearance of a magnetic clasp, in turn, may give rise to security concerns. An observer may see that two ends of a strap, rope, belt, or strand are held together only by a magnetic fixture, and may correctly assume that they are separable with no more than a simple tug. To alleviate this concern, additional mechanical affixing devices such as loops, snaps, and clips are often employed, which virtually eliminate the fundamental advantage of the magnetic closure.
- Another problem with magnetic clasps, especially those in which magnetic surfaces are butted together in the simplest way, is that attraction (and therefore security) is greatest by far when the two surfaces are perfectly parallel and in uniform contact across their respective common planar surfaces. Any partial dislodgment or relative tipping of the two components that damages the perfection of that contact, however slightly, greatly reduces the attractive force and increases the likelihood that the components will separate. The total area of contact also determines the security of the connection, and any lateral movement or sliding of one surface with respect to the other, even while maintaining perfection of the common planar surface, reduces attraction and increases the probability of separation. Hence, the ability of the secured components to move relative to each other increases the probability of complete separation and loss of the jewelry.
- Another problem with existing magnetic jewelry clasps is their size and bulk. Because the mass required to maintain adequate security of the fastening system is rarely consistent with the aesthetic intent of the designer, compensatory design features and compromises are usually required. These and other attempts to overcome deficiencies in the concept have led to increased manufacturing costs. Execution in general has grown from simple to very complex, with a commensurate increase in manufacturing costs.
- While many of the prior art magnetic clasps may be suitable for the particular purposes for which they are intended, they are not optimum solutions for jewelry and other applications, and generally involve a variety of compromises in aesthetics, functionality, ease of use, security, and cost of manufacture. The concealed secure magnetic clasp of the present invention substantially departs from and has substantial advantages over the conventional concepts and designs of the prior art.
- In view of the foregoing disadvantages inherent in known methods and mechanisms for magnetically connecting elements of jewelry and other items, the present invention provides a new and superior method and mechanism that is aesthetically pleasing, secure, easy to use, and inexpensive to manufacture.
- One object of the invention is to enable two ends of a rope, loop, band, belt or other item to be affixed one to the other using a magnetic closure in a unique manner that avoids the problems of prior art.
- Another object of the invention is to provide a magnetic closure with an outer housing having dimensions that force the alignment of the magnetic faces of the two ends, thereby maximizing parallelism and the magnetic bond, and minimizing security risk.
- Another object of the invention is to provide a magnetic closure for jewelry having a decorative outer housing that is a major aesthetic feature of the jewelry, thus rendering the magnetic nature of the closure less obvious.
- Another object of the present invention is to provide a magnetic closure that is economical to manufacture using simplified and low-cost components and assembly techniques.
- Another object of the invention is to provide a magnetic closure for jewelry that is easy to use, minimizing the need for manual dexterity while maximizing security.
- Another object of the invention is to provide a magnetic closure that optionally integrates an intrinsic mechanical lock, achieved without additional moving parts and by using the magnetic attraction of the clasp components to effect a mechanical lock. The optional mechanical lock is simple and easy to use and provides security beyond that of the magnetic clasp itself.
- Another object of the invention is to provide a magnetic closure for jewelry that is optionally configured to minimize the magnetic field of the assembly, thus reducing the likelihood of attracting ferrous detritus in the environment.
- Another object of the invention is to exploit health advantages of magnetic devices, insofar as any exist, by adding magnetic materials to a jewelry item, and thus generating magnetic fields.
- Accordingly, one embodiment of the invention is a jewelry clasp including a magnetic clasp assembly. A first magnetic component has a first mating face and is affixed to a first free end of a band, and a second magnetic component has a second mating face and is affixed to a second free end of the band. A housing is affixed to the second free end of the band and defines a recess for insertion of the first free end. The housing conceals the first and second magnetic components when the magnetic clasp. assembly is engaged, and is configured with internal dimensions that force optimal alignment of the first and second mating faces. In one implementation, the clasp further includes a mechanical lock that is engaged and maintained with the help of the magnetic attraction provided by the magnetic clasp assembly.
- Another embodiment of the invention is a clasp for an item of jewelry. A housing is attached to a first free end of a jewelry band and defines a receptacle for receiving a second free end of the jewelry band. A detent is formed within the receptacle, and a first magnetic component is embedded in and flush with an interior surface of the receptacle. A second magnetic component is attached to the second free end of the jewelry band and is configured to engage and mate with the first magnetic component in a parallel and uniform area of contact to establish a magnetic lock. A hook is attached to the second free end of the jewelry band and is configured to fit within the detent to establish a mechanical lock.
