SEGMENTED PENDANT
A decorative pendant includes a plurality of segments, each being shaped and sized so as to have a selected composite shape, such as, for example, a heart shape, an animal shape, etc. Each of the segments has an aperture extending therethrough, and a pivot rod traverses the apertures of the each of the segments, such that each of the segments is freely rotatable with respect to the pivot rod. The first and last segments are coupled to the ends of the pivot rod, with the remaining segments captured between. One of the segments includes a loop for engagement with a necklace, and one of the segments includes a legend inscribed on a surface that, when the segments hang freely from the pivot rod, lies face-to-face with a surface of an adjoining one of the segments, so as to be visible only when the one of the segments is rotated away from its free-hanging position, relative to the adjacent segment.
This application claims the benefit of U.S. Provisional Patent Application No. 60/912,906 filed Apr. 19, 2007, which provisional application is incorporated herein by reference in its entirety.
BACKGROUND OF THE INVENTION1. Technical Field
The disclosed embodiments of the present invention are related to the field of decorative personal items such a necklaces, pendants, and earrings, and in particular, are related to such items that include multiple elements that are configured to be movable with respect to each other.
2. Description of the Related Art
Jewelry has been a fundamental part of human adornment since prehistory. It has been used to express, among other things, social status, wealth, personal taste, and affiliations. It includes objects such as rings, pins, earrings, bracelets, and pendants, and varies by size, shape, color, material, and complexity.
There is a continuing and consistent interest in new jewelry designs and new variations on old designs.
It will be recognized that a surface 108 of any of the segments 102 can be engraved in this manner so as to hide the engraving until the respective segment 102 is rotated away from the other segments. Engraving can be made on opposite surfaces 108 of the same segment, or alternatively, on face-to-face surfaces 108 of two adjacent segments. The engraving can be selected for the occasion. For example, if the pendant is to be given as a wedding gift, the name of the bride and/or groom may be engraved on the center segment, or one name on each side. Alternatively, the date of the marriage may be engraved. Of course, as further alternatives, special messages appropriate to a particular occasion can be on engraved, according to the purpose for which the pendant is given, including, for example, love messages for a wedding or anniversary gift; birthday messages, and friendship messages.
While only the surface 108a is shown with engraving, any surface can be decorated. For example, according to an embodiment, the front and back faces of the pendant, comprising coplanar surfaces of each of the segments 102, can be decorate by any of a number of known processes, including, for example, etching, engraving, carving, coloring and oxidizing processes, etc. According to an embodiment, a pendant is provided having a plurality of segments, each having at least one surface that lies substantially in a common plane and forming a common face while the segments are hanging vertically. A fanciful design is formed in the face by etching or some other process, such that there is a palpable depth to the design, and the portions of the design that are recessed, with respect to the face, are colored to contrast with a color of the face. The respective colors can be by oxidation, anodization, by deposit of a surface color, or by polishing the material of the pendant. The engraving on the front and back faces may be selected so that when the pendant is in the flat position, one image is shown, but when different segments are rotated relative to each other, a different image is shown.
In one alternative embodiment, the loop 104 is not present. In this embodiment, the design is an ornamental object with a plurality of segments that can rotate relative to each other. In this form, it can sit on a dresser, be a pocket piece of jewelry or other object. Alternatively, a pin can be attached to one of the segments to support it from the rear so it can be a broach.
Referring now to
Assuming a pendant design that has an intended top and bottom, the overall position of the apertures 112 is selected to be above the center of gravity of each of the individual segments 102 when they are oriented according to the design, such that each segment 102 hangs in the desired orientation and the overall shape of the pendant 100 is displayed when the pendant hangs freely.
According to the embodiment of
The pendant 100 is normally hung about an individuals neck by a chain or cord through the loop 104. While hanging freely, the segments each hang vertically, and to an observer, the pendant appears substantially solid. However, because a pendant rarely hangs free when worn about the neck, but instead rests against the wearer's chest, it will move with the wearer, causing the segments to move slightly, with respect to each other, sometimes creating a rippling, liquid appearance.
Referring now to
The segment 102d includes an aperture 112, and the segment 102c includes a blind aperture 128. Each of the apertures 128 and 112 is provided with a chamfer 122, 124 on the facing surfaces of the respective segments 102c, 102d. A small amount of solder 126 is positioned in the blind aperture 128, with the end of the pivot rod resting thereon. An operator applies a small flame to the segment 102c immediately opposite the blind aperture 128, heating only the segment 102c, at the same time applying a slight pressure against the segment 102c to the left, as viewed in the drawings. When the region of the segment 102c around the blind aperture 128 reaches the liquidus temperature of the solder, the solder liquefies, flowing by capillary action, and because of the pressure applied, around the end of the pivot rod 106, allowing the segment 102c to move leftward until the pivot rod 106 bottoms out in the blind aperture 128, as shown in
According to an alternative embodiment, the pivot rod 106 is intentionally slightly too short, and a temporary shim is positioned between the segments 102c and 102d. The operator proceeds as described above, and when the solder melts, leftward pressure on the segment 102c compacts all the segments tightly together, because the pivot rod 106 does not bottom out. The shim is selected to be of a thickness substantially equal to a sum of the desired clearance space between each facing pair of segments. Thus, after the segment 106 cooled, the shim is removed, and the appropriate clearance space is provided. Operating in this manner provides as one advantage that the shim can be made of an insulating material, thus also serving to prevent the accidental heating of the adjacent segment 102d. With regard to the embodiment of
Because the volume of solder required to bond the rod to the segment 102c is miniscule, it can be difficult to provide sufficient solder to form a strong joint, without providing so much that it would flow into the aperture 112 of the adjacent segment 102d, possibly bonding that segment, as well, which of course is not desirable. However, because the chamfers 122, 124 are provided in the surfaces of the segments 102c, 102d, a small cavity is formed between the segments, which is invisible when the pendant 120 is assembled. The cavity has sufficient volume that as excess solder flows from the blind aperture, it flows into the cavity, as shown in

According to an alternate embodiment, the end face of the pivot rod has a rounded, or “rivet head” finish.
In some embodiments the first and last segments are rotatable with respect to the pivot rod, but it is nevertheless important that the pivot rod have a particular orientation when the pendant is hanging freely, so that, for example, the end faces of the pivot rod conform to the outer surface of the first and last segments. In such embodiments, the pivot rod can be rigidly affixed to the segment by which the pendant will hang. e.g., the segment 102a of

Turning now to
In one specific embodiment, a sterling silver was used to make a model substantially as shown in
While principles of the invention have been described primarily with reference to a heart-shaped pendant, a segmented pendant according to the principles of the invention can be provided with any shape that is capable of being divided into segments. Oval shapes, round shapes, diamond shapes and other geometric shapes are particularly adapted to being made from segments according to the invention. A classic round diamond shape with a flat upper surface and cone bottom, ending in a point is another shape particularly adapted for use with the invention. Various fruits may also be made, including apples, pears, and the like.
The term pendant is to be construed broadly, to include, in addition to a pendant configured to hang from a chain or cord to be worn about a user's neck, other items of jewelry and decorative objects, such as, for example, earrings, pins, fobs, hair clips, etc., as well as decorative objects that are not designed to hang, such as a pocket charm or paper weight.
Earrings are particularly suitable for application of the principles of the invention. Such earrings have a plurality of segments, one of which includes the loop for attachment to the wearer's ear. The segments of the earring would therefore rotate freely, providing sparkle and color as they turn with each movement of the wearer's head. The segments can be balanced and weighted in such a way that they easily rotate with respect to each other, with very little force needed. Very light weight segments can be used if desired. In such an embodiment, having the inside surface of the segments a different color may be particularly beneficial since, in this case, the goal of the wearer is to have the segments show different colors as they rotate relative to each other.
The ease with which the segments rotate with respect to each other can be selected based on the desired presentation and use. For example, in some pendant designs, the fit between the segments and the rod can be quite tight so that the segments generally lie flat and only rotate relative to each other when specific force to move them is applied, such as by pressing with the finger or twisting. In other embodiments, the fit is made substantially friction free, so the segments rotate very easily with respect to each other. In such a low friction embodiment, even minor movement of the pendant, or a wind blowing on the pendant, will cause the segments to move relative to each other, so that as the wears moves, one or more of the segments will move relative to each other, exposing parts of the inside surface, and thus its reflective and visual properties, further enhancing the beauty of the pendant.
The segmented pendant may be manufactured using any suitable material, including common and precious metals such as sterling copper, nickel, silver, gold, and platinum, as well as minerals, ceramics, crystal etc. According to an embodiment, individual segments of a pendant are made from different materials, such as, for example, a combination of gold and silver segments. Additionally, gems can be set into the exposed faces of one or more segments, or into the hidden surfaces such that they are invisible until the segments are moved.
As a further alternative, the exposed face may be one material and the inside surface another material. For example, the segment may be made of glass or crystal as a base material with a silver coating applied to the top surface. The pendant will appear flat and silver in color when in the composite shape of
In one embodiment, each segment of the pendant is made from crystal or reflective glass. In the flat position, as shown in
Where used in the specification and claims, the term rotate freely means to rotate in response to changes in acceleration or orientation caused by movement of the object in question. Thus, for example, with regard to the embodiment of
