RING AND PROCESS FOR PRODUCING THE SAME

Abstract

A jewelry ring that includes a sleeve-like or annular substrate made of a precious metal or a precious metal alloy having a specific density 1, and which has an inner surface for contacting a finger, an outer surface, two lateral surfaces and a central cavity for accommodating the finger. A bundle of fibers is wound in multiple windings on at least a part of the outer surface. The fibers are connected to one another by a plastic adhesive having a specific density of 2<1. The fibers have a specific density 3<1. Also a method for manufacturing a jewelry ring, which includes wetting the bundle of fibers with plastic adhesive, fastening a start of the bundle to the sleeve-like or annular substrate, winding the bundle on the sleeve-like or annular substrate, applying pressure to the bundle, curing the plastic adhesive and grinding off peripheral-most fibers.

Claims

DETAILED DESCRIPTION OF THE INVENTION

[0047] The jewelry ring 1 depicted in FIGS. 1 and 2 consist of an annular substrate 2 made of palladium, which has a peripherally circumferential groove 10, in which a roving consisting of a bundle 8 of axially twisted fibers 9 made of carbon having a specific weight of 1.5 g/cm.sup.3, and a diameter of 6 m is wound with approximately 180-200 windings.

[0048] The fibers 9 are adhered to one another and to the groove 10 by means of a transparent epoxy resin adhesive. The peripheral-most fibers 9 are grounded off. The surface of the bundle 8 has a characteristic silk-like sheen.

[0049] FIG. 3 shows a cross-section through a blank for another embodiment of the jewelry ring 1, in which the groove 10 is not bound on one side. To facilitate the winding of the roving, a washer having a diameter corresponding approximately to the right side of the blank is fastened to or pressed onto the left (open) side of the groove 10 during manufacture.

[0050] FIG. 4 depicts a blank for another embodiment of the jewelry ring 1. The blank differs from the embodiment depicted in FIGS. 1 and 2, only in that the peripherally circumferential groove 10 is provided with insular areas 11. These insular areas 11 may, for example, have a lenticular cross-sectional surface perpendicular to a radius of the blank, and may extend from the outer face 4 to the bottom of the groove 10. The fibers 9 (not delineated) are wound around the insular areas 11 in slalom-like fashion relative to the rotational direction on the outer surface 4 having the smaller outer diameter.

[0051] FIGS. 5 through 7 again depict another embodiment of the jewelry ring 1, which differs from the embodiment depicted in FIGS. 1 and 2, only in that the groove 10 and, therefore, the bundle 8 of fibers 9 exhibits a broader width between the two lateral surfaces 5, 6.

[0052] Although, there are different embodiments of the invention, as described above, these are to be understood in the sense that the different features may be used both alone as well as in any arbitrary combination.

[0053] Thus, the invention is not limited simply to the aforementioned, particularly preferred embodiments.
