DE3320590A1 - JEWELERY PIECE AND METHOD FOR THE PRODUCTION OF WIRE OR THE LIKE FROM METAL, ESPECIALLY FROM ALLOYS WITH PRECIOUS METALS - Google Patents

Abstract

1. An item of jewellery consisting of segments of different alloy stages of a noble metal, wherein the individual segments are welded together, characterised in that it is produced from a blank (1) whose segments (3, 4) of different alloy stages have melting points which are close together, wherein the individual segments are fusion-welded together in such a way as to give a progressively changing colour characteristic.

Description

"Piece of jewelery as well as a method for the production of wires or the like. Made of metal, in particular from alloys with Precious metals "

The invention is directed to a piece of jewelry, in particular made of alloys with precious metals, and to a Process for the production of wires, rods, profiles or sheets from metal, in particular from alloys with precious metals.

Jewelery made of precious metals, where the appearance is due to the different color of the metals used receives its special character are known in the most varied of forms. Also method of manufacture such pieces of jewelry or the raw materials are known.

For example, DE-OS 27 33 602 describes a method for producing a piece of jewelry made of platinum with a fine gold plating. In the case of these pieces of jewelry produced by the known method, the brilliance of the color appearance becomes achieved by juxtaposing gold and platinum. Other types are also known. So the compilation of silver and gold in order to achieve similar color effects here as well.

The object of the invention is to create a solution with which a piece of jewelry or primary materials, such as wires,

" ^D " 332053G

Rods, profiles or sheets can be produced which have an essentially constantly changing color gradient.

In a piece of jewelry of the type mentioned, this object is achieved according to the invention in that it is made from a blank, which is made up of individual segments of different alloy levels and thus more different optical appearance is made, the individual segments are welded together.

In terms of method, the object according to the invention is thereby achieved solved that to achieve a substantially steady .g changing color gradient of individual wire, rod, profile or sheet metal segments of different graded alloys and thus produced with different visual appearance and then segments of different types be connected to each other.

With the invention are quite surprising optical and Aesthetic manifestations made possible that are different from jewelry made according to the state of the art do not have a sudden change in color, but take advantage of the differences in the colors of individual alloys make, whereby a transition of individual color levels into one another that is imperceptible to the viewer can be achieved is.

In an embodiment, the invention provides that the different Metal segments are welded together using the melting points that are close together verden. This type of connection is special for the invention This is important because the welding enables a particularly seamless transition between adjacent segments.

In a further embodiment, the invention provides that silver is used as an alloy component and starting from Peingold the jumps to the neighboring element in the alloy content at approx. 50 o / o silver growth lie. It has been shown that these alloy jumps are more common, especially in jewelry Make size possible that are no longer visually perceptible, so that we speak of a steady color transition can be.

Of course, the invention does not apply to this alloy component limited. Thus, in a further embodiment, the invention also provides that the gold to change the color is silver and / or palladium and / or nickel and / or bronze and / or brass or other colored metals or their Alloys are supplied.

According to the invention, two configurations are also possible, which consist in that the gold component per segment varies, e.g. B. falls with the increase in the silver component, or that the gold component per segment is constant

remains, in this case the alloying elements change.

The invention is explained in more detail below with reference to the drawing, for example. This shows in the

Pig. I.

to '4 four different according to the invention

Processed jewelry.

The ring 1 shown in Fig. 1 is designed as a so-called split ring, at the gap 2 of which the largest color jump occurs. Thus, from an area of the purest gold 3 by increasing the silver content, the Color from red, rose »yellow to green, ivory and finally change silver-white in area 4.

^{The ring I 1} shown in FIG. 2 has no color jump in a gap, but opposite dark and light areas which are denoted ^{by 3 1 and V based on the designation in FIG.}

Finally, FIGS. 3 and 4 show other pieces of jewelry made of plates or rods of different colors are made. So in Fig. 3 is a portion z. B. a necklace 5 with a plurality of metal plates 6 shown, which have different color gradients, while in Fig. 4z. B. a part of a bracelet 7 is

is made, again with individual metal plates 8 different color gradients.

Of course, the invention is not restricted to the exemplary embodiments described, but rather in many ways Modify respect without departing from the spirit of the invention. So of course it is Invention not limited to a particular type of jewelry. The procedure according to the invention can be used here be used in a variety of other things, especially precious metals and their alloys come into use. I. E. the invention is not limited to the jewelry sector, it can for example can also be used in electronics when z. B. by constant alloy changes a corresponding Change of heat or current flow in a component should be desired and the like. More.
