Abstract

1. An item of jewellery comprising platinum and high-carat gold, in particular fine gold, wherein the join between the two metals is produced by applying the gold in a solid condition to the platinum and heating the gold to its melting temperature, characterized in that the item of jewellery is formed at least in a region-wise manner from thin high-carat gold foils, in particular fine gold foils (1), as the starting material, which are provided with an applied edge and/or internal reinforcement (2, 3) of platinum.

Description

Die Erfindung richtet sich auf ein Schmuckstück aus Platin und hochkarätigem Gold, insbesondere Feingold, wobei die Verbindung der beiden Metalle durch Aufbringen des Goldes in festem Zustand auf das Platin und die Erhitzung des Goldes auf seine Schmelztemperatur erfolgt ist.The invention is directed to a piece of jewelry made of platinum and high-quality gold, in particular fine gold, the connection of the two metals being effected by applying the gold in a solid state to the platinum and heating the gold to its melting temperature.

Ein derartiges Schmuckstück ist aus der DE-A-2 733 602 der Anmelderin bekannt. Bei dem bekannten Schmuckstück wird Platin als Trägermetall und Ausgangsmaterial benutzt und ein Feingold-Auflage-Metall eingesetzt, das demgemäss die am Platin vorgesehene Auflagefläche vollflächig abdeckt, wobei bei dem bekannten Schmuckstück der Platinanteil wenigstens gleich oder grösser ist als der Feingoldanteil am Gesamtschmuckstück, da die Feingoldauflage im wesentlichen dekorativen Charakter hat und nicht selbst den Hauptteil des Schmuckstückes bilden soll.Such a piece of jewelry is known from DE-A-2 733 602 by the applicant. In the known piece of jewelry, platinum is used as the carrier metal and starting material and a fine gold plating metal is used, which accordingly covers the entire surface of the supporting surface provided on the platinum, with the known piece of jewelry the platinum portion being at least equal to or greater than the fine gold portion of the entire piece of jewelry, since the Fine gold plating has an essentially decorative character and should not itself form the main part of the piece of jewelry.

Aus der DE-C-561 705 ist darüber hinaus ein Verfahren bekannt, bei dem auf Goldblech ausreichender Dicke nach dem Dubleeverfahren dünne Platinbleche aufgeschweisst werden. Derartige Schmuckstückplatten sollen für Dosen, Uhrengehäuse u.dgl. eingesetzt werden, d.h. das dortige Verfahren bewirkt keine Festigung des Goldbleches, dieses soll von vornherein ausreichend stark bemessen sein.From DE-C-561 705 a method is also known in which thin platinum sheets are welded onto gold sheet of sufficient thickness by the duble method. Such trinket plates are intended for cans, watch cases and the like. be used, i.e. the process there does not strengthen the gold sheet, it should be sufficiently strong from the start.

Andere Schmuckteile, aus bereichsweise dünnen Blechen gebildet, sind auch aus der US-A-3 955 934 und 4107 947 bekannt, wobei dort eine Schmuckwirkung durch Einlegen von Blechteilen aus jeweils anderen Edelmetallen in entsprechende Öffnungen eines Edelmetallgrundbleches erzielt wird und die gesamten Blechteile auf einer Trägerplatte aufgeschweisst sind.Other jewelry parts, formed from thin sheet metal in some areas, are also known from US Pat. Nos. 3,955,934 and 4107,947, where a jewelry effect is achieved by inserting sheet metal parts made of different noble metals into corresponding openings in a noble metal base sheet and the entire sheet metal parts on one Carrier plate are welded on.

Bei der Verarbeitung von hochkarätigen Goldblechen als Ausgangsmaterial ist der Verarbeiter an gewisse natürliche Grenzen gebunden, da hochkarätiges Gold selbst in festem Zustand nicht immer die gewünschte Festigkeit aufweist, die für Schmuckstücke notwendig ist und im übrigen die Gefahr besteht, dass bei dünner werdenden Blechen die Ränder ausfransen, einreissen, sich versehentlich deformieren u.dgl. mehr.When processing high-quality gold sheets as the starting material, the processor is bound to certain natural limits, since high-quality gold does not always have the desired strength, even in the solid state, which is necessary for jewelry and, moreover, there is a risk that the edges of thinning sheets fray, tear, accidentally deform, and the like. more.

Aufgabe der Erfindung ist die Schaffung einer Lösung, mit der ein Überschreiten dieser natürlichen Bearbeitungsgrenzen von hochkarätigen Goldblechen möglich ist.The object of the invention is to provide a solution with which it is possible to exceed these natural processing limits of high-quality gold sheets.

Bei einem Schmuckstück der eingangs bezeichneten Art wird diese Aufgabe gemäss der Erfindung dadurch gelöst, dass das Schmuckstück wenigstens bereichsweise aus dünnen hochkarätigen Goldblechen, insbesondere Feingoldblechen als Ausgangsmaterial gebildet ist, die mit einer aufgebrachten Rand- und/oder Innenarmierung aus Platin versehen sind.In the case of a piece of jewelry of the type mentioned at the outset, this object is achieved according to the invention in that the piece of jewelry is formed at least in regions from thin high-quality gold sheets, in particular fine gold sheets, as the starting material, which are provided with an applied edge and / or inner reinforcement made of platinum.

Es hat sich überraschenderweise gezeigt, dass eine feine Randarmierung aus Platin für ein dünnes Goldblech oder -blatt ausreicht, welches in der in der Gattung angegebenen Verfahrensweise erzeugt worden ist, diesem eine sehr grosse Festigkeit zu verleihen, die eine Weiterverarbeitung möglich macht. Bei vergleichsweise grossen Goldblättern kann es sinnvoll sein, statt oder neben einer Randarmierung eine Innenarmierung vorzusehen, wobei mit Innenarmierung sowohl eine Zwischenlagerung von Platinbereichen in der Goldblattfläche gemeint ist, als auch die Zwischenlage von Platin in der Fläche, d.h. möglicherweise zwischen zwei Goldblättern, so dass eine derartige Armierung von aussen nicht oder nur bereichsweise sichtbar ist. Auch kann die Rand- und Innenarmierung zu einem einstückigen, dünnen Platinblech zusammengefasst sein, das mit dem Goldblech ein Bi-Metallblech bildet. Unter dem Ausdruck «Armierung» wird hier ausschliesslich verstanden, dass der Gewichtsanteil von Platin geringer als der des Goldes als Ausgangsmaterial ist. In Ausgestaltung sieht die Erfindung vor, dass die Goldbleche eine Stärke von weniger als 0,5 mm aufweisen.Surprisingly, it has been shown that a fine edge reinforcement made of platinum is sufficient for a thin gold sheet or sheet, which has been produced in the procedure specified in the genus, to give it a very high strength, which makes further processing possible. In the case of comparatively large gold leaves, it may make sense to provide internal reinforcement instead of or in addition to an edge reinforcement, whereby internal reinforcement means both an intermediate storage of platinum areas in the gold leaf surface and the intermediate layer of platinum in the surface, i.e. possibly between two gold leaves, so that such reinforcement is not visible from the outside or only in certain areas. The edge and inner reinforcement can also be combined to form a one-piece, thin platinum sheet, which forms a bimetal sheet with the gold sheet. The term “reinforcement” is understood here exclusively to mean that the proportion by weight of platinum is less than that of gold as the starting material. In an embodiment, the invention provides that the gold sheets have a thickness of less than 0.5 mm.

Das Schmuckstück weist zweckmässigerweise ein Innenfeld aus hochkarätigem Gold mit einer Umgrenzung aus Platin auf, wobei innerhalb der Platin-Umgrenzung in dem Goldinnenfeld Platin-Elemente angeordnet oder in weiterer Ausgestaltung die Platin-Elemente als mit der Platin-Umgrenzung verbundenes Skelett ausgebildet sind.The piece of jewelry expediently has an inner field made of high-quality gold with a platinum border, platinum elements being arranged within the platinum border in the gold inner box, or in a further embodiment the platinum elements are designed as a skeleton connected to the platinum border.

Die Platin-Umgrenzungen, die Platin-Elemente innerhalb des Goldes und die Platin-Skelett-Elemente können geometrisch einfache Formen aufweisen und/oder, wie dies die Erfindung auch vorsieht, innerhalb des oder der Goldfelder beliebiger Konfiguration und Gestaltung angeordnet sein.The platinum boundaries, the platinum elements within the gold and the platinum skeleton elements can have geometrically simple shapes and / or, as the invention also provides, can be arranged within the gold field or fields of any configuration and design.

Ein besonderer Schmuckeffekt kann dadurch erreicht werden, dass die Platin-Elemente nur auf einer Seite des innerhalb der Platin-Umgrenzung durchlaufenden Goldinnenfeldes angeordnet sind.A special decorative effect can be achieved in that the platinum elements are arranged only on one side of the gold inner field passing through the platinum boundary.

Die Erfindung ist nachstehend anhand der Zeichnung beispielsweise näher erläutert. Diese zeigt in

  • Fig. 1, 2, 5 und 9 und 10 vereinfacht wiedergegebene Schmuckstücke mit einer Randarmierung von Feingoldblechen durch Platin mit unterschiedlicher Gestaltung, und in
  • Fig. 3, 4, 6, 7 und 8 Schmuckstücke mit einer Rand- und Innenarmierung in vereinfachter Darstellung.
The invention is explained below with reference to the drawing, for example. This shows in
  • Fig. 1, 2, 5 and 9 and 10 simplified reproduced jewelry with an edge reinforcement of fine gold sheets by platinum with different designs, and in
  • 3, 4, 6, 7 and 8 pieces of jewelry with an edge and inner reinforcement in a simplified representation.

Ein in den Figuren mit 1 bezeichnetes Feingoldblech oder -blatt ist mit einer Randarmierung 2 aus Platin versehen, wobei die Verbindung zwischen Platin und Feingold gemäss DE-PS 2733602 erfolgt, d. h. das Feingoldblatt wird z. B. auf einen Platindraht aufgelegt und in diesem Bereich auf seine Schmelztemperatur erhitzt und damit mit dem Platin verbunden. Nachträglich kann eine weitere Bearbeitung erfolgen, z.B. das Feingoldblatt mit der Randarmierung weiter verdünnt werden, was durch die Erfindung bis zu Wandstärken möglich ist, die bisher nicht erreichbar waren ohne dass man nicht Gefahr lief, dass die Ränder ausfransen, einreissen o.dgl.A fine gold sheet or sheet designated 1 in the figures is provided with an edge reinforcement 2 made of platinum, the connection between platinum and fine gold taking place according to DE-PS 2733602, i. H. the fine gold leaf is z. B. placed on a platinum wire and heated in this area to its melting temperature and thus connected to the platinum. Further processing can be carried out subsequently, e.g. the fine gold leaf can be further thinned with the edge reinforcement, which is possible with the invention up to wall thicknesses that were previously not possible without running the risk of the edges fraying, tearing or the like.

Zusätzlich zu den Randarmierungen 2 können auch Innenarmierungen 3 vorgesehen sein, z.B. in geometrisch einfachen Formen, wie etwa in Fig. und 6 oder in Konturen beliebiger Ausgestaltung, wie in Fig. 4 angedeutet ist.In addition to the edge reinforcements 2, inner reinforcements 3 can also be provided, for example in geometrically simple shapes, such as for example in FIG Fig. And 6 or in contours of any configuration, as indicated in Fig. 4.

In Fig. 5 ist eine Besonderheit gezeigt, nämlich diejenige, dass die Randarmierung 2 einstückig in die Fläche des Feingoldblattes 1, dort als Dreieckteil, einläuft, was mit 2' bezeichnet ist.5 shows a special feature, namely that the edge reinforcement 2 runs in one piece into the surface of the fine gold leaf 1, there as a triangular part, which is denoted by 2 '.

Die Fig. 7 und 8 zeigen Möglichkeiten, die Feingoldfläche 1 mit einem Skelett aus Platinstäben o.dgl. auszurüsten, im Falle der Fig. 7 aus miteinander verbundenen oder aus nicht miteinander verbundenen Stäben, wie dies in Fig. 8 angedeutet ist.7 and 8 show possibilities of the fine gold surface 1 or the like with a skeleton made of platinum rods. equip, in the case of FIG. 7 from interconnected or non-interconnected rods, as indicated in Fig. 8.

Die Fig.9 und 10 zeigen wiederum lediglich Randarmierungen 2', die allerdings sowohl den Aussenrand als auch die Ränder von Durchbrüchen 5 bzw. 5' umgrenzen.9 and 10 again only show edge reinforcements 2 ', which, however, delimit both the outer edge and the edges of openings 5 and 5', respectively.

Natürlich sind die beschriebenen Ausführungsbeispiele noch in vielfacher Hinsicht abzuändern, ohne den Grundgedanken der Erfindung zu verlassen. So ist die Erfindung insbesondere nicht auf eine bestimmte, in den Figuren wiedergegebene Kontur oder Form, weder eines Schmuckstückes noch der Armierungseinlagen oder -umgrenzungen, beschränkt. Die nach der Erfindung hergestellten platinarmierten Goldbleche dünner Wandstärke können zu vielfältig gestaltetem Schmuck, Geräten oder Objekten weiterverarbeitet werden. Wesentlich für die Erfindung ist auch, dass die Rand- und Innenarmierung 2, 3 zu einer ganzflächigen Armierung aus dünnem Platinblech zusammengefasstsein kann, d.h. ein Bi-Metalldünnblech aus Platin einerseits und z.B. Feingold andererseits für die Schmuckgestaltung o.dgl. zur Verfügung gestellt wird, wobei dieses Bi-Metalldünnblech hervorragende Verarbeitungs- und Festigkeitseigenschaften aufweist.Of course, the exemplary embodiments described can be modified in many ways without departing from the basic idea of the invention. In particular, the invention is not limited to a specific contour or shape shown in the figures, neither of a piece of jewelry nor of the reinforcing inserts or boundaries. The platinum-reinforced gold sheets of thin wall thickness produced according to the invention can be further processed into a variety of jewelry, devices or objects. It is also essential for the invention that the edge and inner reinforcement 2, 3 can be combined to form a full-surface reinforcement made of thin platinum sheet, i.e. a bi-metal thin sheet made of platinum on the one hand and e.g. Fine gold on the other hand for the jewelry design or the like. is made available, this bi-metal thin sheet has excellent processing and strength properties.
