Abstract

The tension ring is slightly elastic and has a gap for the insertion of a precious stone. In order to enhance the appearance of the stainless steel ring (10) its surface is covered with a layer of a precious metal (20). Both materials (10,20) are already joined during the production process by a specific thermal and mechanical treatment. The cover (20) penetrates the material of the core (10), creating a seamless layer.

Description

Die Erfindung betrifft einen Spannring gemäß dem Oberbegriff des Patentanspruchs 1 sowie ein Verfahren zur Herstellung eines derar­ tigen Spannrings.The invention relates to a clamping ring according to the preamble of Claim 1 and a method for producing a derar clamping ring.

Als Spannringe werden in technischer Hinsicht solche Ringe bezeichnet, deren Ringschiene einen meist radial verlaufenden Spalt aufweist, so daß zwei Stirnseiten dieser Ringschiene sich im wesent­ lichen gegenüberliegen. Durch bearbeitungstechnische Maßnahmen wird dieser Ringschiene eine ausreichende Spannung derart verliehen, daß in diesem Spalt zwischen den Enden der Ringschiene ein Schmuckteil, beispielsweise ein Brillant, gehalten wird. Als Material für die Ringschiene wurde bisher beispielsweise Platin verwendet, d. h., ein Platinstrang wurde durch Schmieden und Ziehen so bearbeitet, daß er einerseits die gewünschte Ringschienenform, andererseits die gewünschte Haltekraft für das Schmuckteil zwischen den Stirnseiten der Ringschiene gewährleistet.In technical terms, such rings are used as tension rings referred to, the ring rail has a mostly radial gap has, so that two end faces of this ring rail essentially opposite. Through processing measures this ring rail is given sufficient tension such that a piece of jewelry in this gap between the ends of the ring band, for example, a diamond is held. As material for the Ring rail has previously been used for example platinum, i. i.e., a Platinum strand was worked by forging and drawing so that it on the one hand the desired ring rail shape, on the other hand the Desired holding force for the jewelry part between the end faces the ring rail ensures.

Die hierfür geeigneten Edelmetalle wie z. B. Platin sind jedoch sehr kostspielig, so daß derartige Spannringe in der Regel im oberen Preissegment angesiedelt sein müssen.The suitable precious metals such. B. Platinum are very costly, so that such clamping rings usually in the upper Price segment must be located.

Aufgabe der Erfindung ist es, eine Möglichkeit zu schaffen, einen derartigen Spannring mit im wesentlichen gleichen Materialeigen­ schaften und gleicher Ästhetik zu schaffen, jedoch wesentlich kostengünstiger.The object of the invention is to create a way one such clamping ring with essentially the same material properties and create the same aesthetics, but essential cheaper.

Erfindungsgemäß wird diese Aufgabe gemäß dem kennzeichnenden Teil des Patentanspruchs 1 gelöst. According to the invention, this object is according to the characterizing part of claim 1 solved.  

Die Verwendung von mehreren Materialien bei Schmuckteilen ist für sich gesehen nicht neu, beispielsweise wird durch Aufschieben, Aufclipsen ein mehrteiliges Schmuckelement erzeugt. Der Grundgedanke der Erfindung besteht aber darin, eine Materialverbindung zwischen Kern und Mantel herzustellen, die bereits beim Ausgangsprodukt, einem Materialstrang, vorgegeben sein muß und die durch die eingangs erwähnten Verarbeitungsstufen vom Materialstrang zur fertigen Ring­ schiene und die daraus resultierenden mechanischen und thermischen Beanspruchungen geprägt wird, ohne daß insbesondere die Spannkraft der Ringschiene beeinträchtigt wird.The use of multiple materials in jewelry is for seen not new, for example by postponing, Clip on creates a multi-part decorative element. The basic idea the invention is, however, a material connection between To produce the core and the sheath that are already in the starting product, a strand of material, must be specified and by the input mentioned processing stages from the material strand to the finished ring rail and the resulting mechanical and thermal Stresses is shaped without the resilience in particular the ring band is impaired.

Gemäß einer besonderen Ausgestaltung ist vorgesehen, daß das Material des Kerns Edelstahl ist, der einerseits günstiger als Platin ist, andererseits aber nach den Erfahrungen des Erfinders die notwendige Spannkraft sicherstellt und auch mit dem aus Platin gebildeten Mantel einerseits eine innige Grenzschichtverbindung eingeht, die andererseits aber zu keinen inneren Kräften oder Bean­ spruchungen führt, die die Funktion des Spannringes beeinträchtigen.According to a special embodiment it is provided that the Material of the core is stainless steel, which is cheaper than on the one hand Platinum is, on the other hand, according to the experience of the inventor ensures the necessary clamping force and also with that made of platinum formed coat on the one hand an intimate boundary layer connection comes in, but on the other hand no inner forces or bean stresses that affect the function of the clamping ring.

In der Figur ist die Ringschiene RS eines solchen Spannringes dar­ gestellt, wobei der erfindungsgemäße Aufbau aus Kern und Mantel an der Stirnseite sichtbar ist, nämlich ein Kern 10 aus Edelstahl und ein Mantel 20 aus Platin. In der Regel wird ein nicht dargestellter Schmuckstein vom Edelstahl-Mantel gehalten werden, d. h., die Funktion des Spannrings ist auch dahingehend zu charakterisieren, daß die mechanische Komponente, d. h. die Aufbringung der Spannkraft, vom Edelstahlkern gewährleistet ist, während die ästhetische Komponente und die Werthaltigkeit des Spannrings durch den Platin- Mantel gewährleistet bleibt, der dieselben gestalterischen Mög­ lichkeiten bietet wie der "konventionelle" Spannring aus Voll- Platinmaterial.In the figure, the ring rail RS of such a clamping ring is shown, the structure according to the invention consisting of core and jacket is visible on the front side, namely a core 10 made of stainless steel and a jacket 20 made of platinum. As a rule, a gemstone (not shown) will be held by the stainless steel jacket, ie the function of the clamping ring must also be characterized in such a way that the mechanical component, ie the application of the clamping force, is guaranteed by the stainless steel core, while the aesthetic component and the intrinsic value the clamping ring is guaranteed by the platinum jacket, which offers the same design options as the "conventional" clamping ring made of solid platinum material.

Ein typischer Herstellungsprozeß für einen erfindungsgemäßen Spann­ ring sieht vor, daß im Verlauf der Formung des bereits aus Kern und Mantel bestehenden Materialstrangs durch geeignete thermische und mechanische Behandlung zum Beispiel bei Schmiede- und/oder Zieh­ vorgängen metallurgische Grenzschichtprozesse initiiert werden, durch die eine fugenlose Diffusion der angrenzenden Materialien erreicht wird, d. h. die Struktur des Materialgefüges wird kontrolliert so verändert, daß die gewünschten mechanischen Eigen­ schaften der Ringschiene erreicht werden. Eine bevorzugte Möglich­ keit besteht in der Definition von thermischen Behandlungsstufen beim Ziehen, insgesamt kann durch das erfindungsgemäße Verfahren eine innige Verbindung zwischen den beiden Materialien des Kerns und des Mantels erreicht werden, ohne daß unerwünschte Grenzschicht­ kräfte oder Beanspruchungen auftreten.A typical manufacturing process for a instep according to the invention ring provides that in the course of forming the core and Coat existing strand of material through suitable thermal and mechanical treatment for example in forging and / or drawing processes metallurgical boundary layer processes are initiated,  due to the seamless diffusion of the adjacent materials is achieved, d. H. the structure of the material structure becomes checked so changed that the desired mechanical properties shafts of the ring rail can be reached. A preferred option speed is the definition of thermal treatment levels when pulling, overall can by the inventive method an intimate connection between the two materials of the core and of the jacket can be achieved without undesired boundary layer forces or stresses occur.
