BACKGROUND OF THE INVENTION

The present invention relates generally to magnetic clasps and more particularly to a magnetic clasp having magnets that are completely obscured.

Clasps are used to secure pieces of jewelry, such as bracelets and necklaces. Traditional clasps are often difficult to put on as the wearer must open the catch attached at one end of the piece of jewelry and then properly insert a ring attached at the other end of the piece of jewelry into the opening of the clasp. Traditional clasps can also be difficult to open/remove. Such traditional clasps are not only difficult to manipulate, but are often unattractive and may detract from the overall appearance of the piece of jewelry.

One of the solutions to traditional jewelry clasps are magnetic clasps. Magnetic clasps make it much easier for the wearer to put on and take off a piece of jewelry. However, the magnet(s) of a magnetic clasp are typically visually apparent. This detracts from the visual appearance of the piece of jewelry.

Thus, there is a need for a magnetic clasp having magnets that are completely visually obscured.

BRIEF SUMMARY OF THE INVENTION

A magnetic clasp having completely visually obscured magnets is disclosed. The magnetic clasp includes an end cap, a first magnet (disposed within the end cap), a sleeve, a divider (dividing the sleeve into two inner portions) and a second magnet (disposed within one of the inner portions of the sleeve).

The end cap has an end wall having an inner surface and an outer surface, and a side wall having an inner surface and an outer surface, the side wall extending perpendicularly from the end wall. The inner surface of the end wall and the inner surface of the sidewall form a cavity. The cavity is configured to secure a first end of an object.

The first magnet is disposed adjacent to the inner surface of the end wall such that the first magnet is completely visually obscured when the first end of the object is secured within the cavity of the end cap.

The sleeve has an inner surface and an outer surface.

The sleeve is divided into two portions by a divider. The divider has a first side and a second side. The divider is configured to divide the inner surface of the sleeve into a first inner portion and a second inner portion. The first inner portion is bounded by a first portion of the inner surface and the first side of the divider. The second inner portion is bounded by a second portion of the inner surface and the second side of the divider. The first inner portion is configured to enclose the end cap.

The second magnet is disposed adjacent to the second side of the divider such that the second magnet is completely visually obscured when a second end of the object is secured within the second inner portion of the sleeve.

The object may be a piece of jewelry, such as a necklace or a bracelet.

The sleeve may be cylindrically shaped, rectangularly shaped, or triangularly shaped.

The sleeve may have flanged edges that define a recess therebetween.

The recess may be filled with a decorative material, such as a beaded skin overlay.

The end cap and/or sleeve may be made of a non-magnetic material. The end cap and/or sleeve may be made of a magnetic material. If the sleeve is made of a magnetic material, the first magnetic is not required. If the end cap is made of a magnetic material, the second magnet is not required.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings wherein the showings are for purposes of illustrating preferred embodiments of the present invention only, and not for purposes of limiting the same, FIGS. [0026] 1-7 illustrate a magnetic clasp 10 having magnets 28, 56 that are completely visually obscured. The magnetic clasp 10 includes a sleeve 12 and an end cap 40.
The [0027] sleeve 12 has an inner surface 14 and an outer surface 16. The sleeve 12 has a divider 18 that divides the inside of the sleeve into a first inner portion 24 and a second inner portion 26. Preferably, the divider 18 is made of the same material as the sleeve 12. This gives the finished piece a clean, sleek appearance.
The first [0028] inner portion 24 is configured to enclose the end cap 40. A magnet 28 is positioned in the second inner portion 26. One end of an object 60, such as a piece of jewelry, is secured within the second inner portion 26 such that the magnet 28 is completely visually obscured.
The [0029] end cap 40 is defined by an end wall 42 and a side wall 48. The side wall 48 extends perpendicularly from the end wall 42. The end wall 42 has an inner surface 44 and an outer surface 46. The side wall 48 has an inner surface 50 and an outer surface 52. The inner surfaces 44 of the end wall and the inner surface 50 of the side wall form a cavity 54. The cavity 54 is configured to secure one end of the object 60. As discussed above, the other end of the object 60 is secured in the second inner portion 26 of the sleeve. The ends of the object 60 can be secured in the second inner portion 26 and the cavity 54 of the end cap respectively, using any conventional means, e.g., gluing or crimping.
A [0030] magnet 56 is disposed within the cavity 54 of the end cap 40 adjacent to the inner surface 44 of the end wall. When the end of the object 60 is secured in the cavity 54 of the end cap, the magnet 56 in the end cap is completely visually obscured.
As can be seen in FIGS. 2 and 3, the [0031] end cap 40 is enclosed within the first inner portion 24 of the sleeve such that the magnetic clasp is held securely in place. In exemplary embodiments, the end cap 40 is completely enclosed in the sleeve 12 such that the end cap 40 is not visible when the magnetic clap 10 is in a secured position.
As shown in FIGS. [0032] 1-3, the sleeve 12 may have flanged ends 30 which create a recess 32 in the outer surface of the sleeve 16. A decorative material may be placed within this recessed outer surface of the sleeve. For example, FIG. 1 shows a decorative beadwork skin affixed to the recessed portion 32 of the sleeve. Other decorative embellishments could be used, for example fabric cording, suede fabric, leather fabric, etc. The recess could be filled with a metal material. For example, the sleeve 12 (including the flanged ends 30) could be constructed of a copper material and the recess could be filled with sterling silver. Stones such as precious or semi-precious gems could be affixed to the outer surface of the sleeve. Various materials, such as wood, stone or Lucite® could be inlayed in the recessed portion 32 of the sleeve. In alternative embodiments, such as the one shown in FIG. 4, the sleeve 12 does not include flanged ends and a recessed middle portion therebetween. In the exemplary embodiment shown in FIG. 4, the sleeve 12 has a smooth, level surface. However, embellishments such as stones could be added to a sleeve 12 that does not include a recessed portion.
It will be appreciated that various embodiments may have different shaped sleeves and corresponding end caps. For example, the [0033] sleeve 12 and end cap 40 shown in FIGS. 1-5 are cylindrical in shape, the sleeve 12A shown in FIG. 6 is triangular in shape, and the sleeve 12B shown in FIG. 7 is rectangular in shape. The end caps for the embodiments shown in FIGS. 6 and 7(not shown) have corresponding shapes to the sleeves 12A and 12B, shown in FIGS. 6 and 7 respectively, such that the end cap can be enclosed within the first inner portion of the sleeve. It will be appreciated that the sleeve (and also therefore end caps) can be shapes other than those shown herein. For example, the sleeves (and end caps) could be oval, hexagonal or octagonal in shape.
The [0034] magnet 28 shown in the figures is circular, however, it will be appreciated that the magnet(s) can be virtually any shape, e.g., triangular, square, etc.
As shown in FIG. 1, the [0035] sleeve 12 may be attached to a first end of an object 60 and the end cap 40 may be attached to a second end of the object 60. The magnetic clasp 10 of the present invention is ideally suited to be attached to a piece of jewelry, such as a necklace or bracelet. However, it will be appreciated that the magnetic clasp 10 may be attached to other types of objects, for example a belt.
The [0036] object 60 may be made out of any one or combination of various materials. For example, the object 60 may be made of a metal material, for example gold or sterling silver. Such metal materials may be mesh. The metal material may be a magnetic or non-magnetic metal material. The object 60 may also be made out of a fabric, for example silk cord, leather, plastic tubing or fiber tubing. Such materials may be braided. The object 60 could be round in shape (such as is shown in FIG. 1). It will be appreciated that the object 60 can be other shapes, e.g., oval, square, triangular, hexagonal, etc.
The [0037] magnetic clasp 10 is preferably constructed of a metal material. The metal material may be a non-magnetic material, such as sterling silver. Alternatively, the magnetic clasp 10 could be constructed, at least in part, of a magnetic material. For example, the sleeve 12 could be constructed of a magnetic material. If the sleeve is constructed of a magnetic material, the magnet 56 normally in the end cap 40 is not required. Similarly, if the end cap 40 is constructed of a magnetic material, the magnet 28 normally in the sleeve 12 is not required.
Additional modifications and improvements of the present invention may also be apparent to those of ordinary skill in the art. Thus, the particular combination of parts described and illustrated herein is intended to represent only a certain embodiment of the present invention, and is not intended to serve as a limitation of alternative devices within the spirit and scope of the invention.
