Abstract

An item of jewellery, e.g. a ring, bracelet, bangle, watch, etc, has one or more magnets (1) in an annular arrangement (2). The magnetic pole(s) of one polarity (e.g. S) are distributed over at least a major sector, and preferably 360 degrees, of the annular arrangement at its radially-outward circumference, while the magnetic pole(s) of the opposite polarity (e.g. N) are presented at the radially-inward circumference of the annular to arrangement. The magnets are at least partially surrounded, but preferably completely enclosed, in decorative metal such as gold, silver, platinum, or their alloys. A perceptible attractive force may be established between a couple wearing a pair of the jewellery items in sufficiently close proximity and having complementary magnetic polarities, e.g. when one person wears a wedding ring having outwardly directed south poles, and the other person wears a wedding ring having outwardly directed north poles.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIGS. 1 and 2 show a first item of jewellery according to an aspect of the current invention. As already noted above, references in this specification to items of jewellery include, but are not limited to, items of personal adornment such as watches, rings, bracelets, bangles, brooches, cameos, ear-rings, lockets, pendants, and the like.
A series of 16 permanent magnets 1 are arranged in an annular arrangement indicated by the dotted outline 2. Although the magnets may be of any suitable shape and material, in this embodiment the magnets are cuboid and preferably made of rare earth materials, for example sintered Nd—Fe—B (Neodymium-Iron-Boron).
Each magnet has opposite poles at opposite large faces. The magnets are annularly arranged with like poles similarly oriented, i.e. all poles of one polarity are directed radially outwardly, and all poles of the opposite polarity are directed radially inwardly. In the arrangement shown in FIGS. 1 and 2, all south poles are directed outwardly and all north poles are directed inwardly, as is indicated by the labels S and N in FIG. 1.
The magnets are arranged over 360 degrees of the annular arrangement (as shown), or at least a major sector of it, in a substantially continuous series. Adjacent magnets abut one another or, as shown in FIGS. 1 and 2, adjacent magnets are spaced slightly apart from one another. One or more of the spaces between adjacent magnets may be made large enough to accommodate another element of the item of jewellery, for example a gemstone or other decorative feature; or in the case of a wrist watch, the magnets may be distributed around the wrist strap or band, leaving a gap to accommodate the timepiece or watch bezel.
FIGS. 3 and 4 show a second item of jewellery according to an aspect of the current invention. In this embodiment two permanent magnets 3 are arranged in an annular arrangement indicated by the dotted outline 4. In this embodiment the magnets are semi-circular arc-shapes. Other numbers of magnets having other arcuate shapes may be used. For example, four quadrant-shaped magnets or a larger number of smaller arc-shaped magnets may be used.
Each magnet has opposite poles at opposite, inward and outward, circumferential faces. The magnets are annularly arranged with like poles similarly oriented, i.e. poles of one polarity are directed radially outwardly, and poles of the opposite polarity are directed radially inwardly. In the arrangement shown in FIGS. 3 and 4, the south poles are directed outwardly and the north poles are directed inwardly, as is indicated by the labels S and N in FIG. 3.
The magnets may abut one another or, as shown in FIGS. 3 and 4, may be spaced slightly apart from one another. One or both of the spaces may be made large enough to accommodate another element of the item of jewellery, for example a gemstone or other decorative feature; or in the case of a wrist watch, the magnets may be distributed around the wrist strap or band, leaving a gap to accommodate the timepiece or watch bezel.
FIGS. 5 and 6 show a third item of jewellery according to an aspect of the current invention. This embodiment has a single annularly-shaped permanent magnet 5.
The magnet has opposite poles at opposite, inward and outward, circumferential faces. In the case of multiple north and south poles, the magnet has like poles similarly oriented, i.e. poles of one polarity are directed radially outwardly, and poles of the opposite polarity are directed radially inwardly. In the arrangement shown in FIGS. 5 and 6, the south pole or poles is or are directed outwardly and the north pole or poles is or are directed inwardly, as is indicated by the labels S and N in FIG. 3. These labels indicate either multiple north and south poles, or a circumferential distribution of single north and south poles.
The items of jewellery described above preferably take an annular shape as indicated by the dotted outlines 2, 4 and 6 in FIGS. 1 to 6. Examples of such annular items of jewellery include a ring (for example for wearing on a finger or other digit such as a thumb or toe), or a bracelet or bangle, or a watch having a wrist strap or band. Particularly preferred items of jewellery according to aspects of the current invention include engagement rings, wedding bands and wrist watches.
Each of the magnet or magnets in the jewellery item is at least partially surrounded, or totally enclosed, by a decorative metal, for example a noble metal such as gold, silver, platinum, or alloys of these. Other metals or alloys, for example, pewter or brass, may be used. The metal is preferably shaped in an annulus as shown schematically by the dotted outlines 2, 4 and 6. Of course variations accommodating aesthetic design features into the jewellery may be incorporated without departing from the scope of the invention as defined by the accompanying claims.
The magnets in the embodiments described above may be secured in place by any suitable method, for example by using an adhesive, or by claws as would be well known by one skilled in the manufacture of jewellery.
In one mode, the decorative metal is shaped into an annulus, and one or more cavities are formed to house a respective magnets. In one arrangement, adjacent magnets are separated from one another by a wall of decorative metal between adjacent cavities.
The magnets may be magnetised either before or after incorporating into the item of jewellery.
Although only one magnetic orientation has been shown in the arrangements described above and shown in the Figures, i.e. with the south pole or poles directed outwardly and the north pole or poles directed inwardly, it is to be appreciated that the magnet or magnets may be arranged with the magnetic polarity in the opposite orientation, i.e. with the north pole or poles directed outwardly and the south pole or poles directed inwardly.
The aspect of the invention as described above has particular application when used in conjunction with a similar item of jewellery. Preferably, two people each wear similar items of jewellery as described above. The two jewellery items have opposite orientations of the magnetic poles but are otherwise functionally, if not aesthetically, similar.
By way of example the following description relates to a pair of wedding bands or rings to be worn by a couple. One wedding band has north poles facing outward and south poles facing inward and is worn by one person, whereas the other wedding band has south poles facing outward and north poles facing inward and is worn by the other person. When the rings are brought into a sufficiently close proximity, such as when the couple holds hands, or are about to hold hands, the rings are magnetically attracted to one another and the couple feel an attractive force which tends to pull the rings, and the couple's hands, closer together.
It is to understood that each of the rings only presents one pole radially outwardly, and the outwardly presented poles of the pair of rings are of opposite polarity. The rings, when worn and in sufficiently close proximity to one another, will therefore always attract and not repel one another, regardless of their orientation on the fingers.
It will be appreciated that an attractive force can be created between a couple wearing items of jewellery as described above and claimed herein, when the items of jewellery have complementary magnetic polarities.
It is envisaged that jewellery having one magnetic polarity orientation will be marketed for one group of people, e.g. females, or more particularly heterosexual females, while jewellery having an opposite magnetic polarity orientation will be marketed for another group of people, e.g. males, or more particularly heterosexual males. It is further envisaged that a complementary pair of jewellery items having opposite orientation of magnetic polarities will be marketed to couples, and particularly to engaged or married couples.
It will also be understood that although the jewellery described is generally to be worn about a part of the body, the current invention is not limited to annular items of jewellery. That is, the annular magnetic arrangement does not necessarily need to be housed in an annularly shaped-item of jewellery. For example, the jewellery does not need to have an aperture which extends through the annular magnetic arrangement. The magnets may be arranged annularly as a border or rim about a locket, medallion or other ornamental adornment, for example.
The foregoing describes the invention including preferred forms and methods thereof. Alterations and modifications as will be obvious to those skilled in the art are intended to be incorporated within the scope of the invention as defined in the accompanying claims.
It is to be noted that the alphanumeric characters appearing in parentheses in claim 1 are references to features so labelled in the drawings and are not to be interpreted as limiting the invention claimed to any particular arrangement or to any particular polarity of the magnetic poles.
