Description

Die Erfindung bezieht sich auf einen Schmucksteinverbund bei dem eine Vielzahl von nebeneinander angeordneten Schmucksteinen in einem Gitter gehalten werden sowie auf ein Verfahren zur Herstellung eines Schmucksteinverbundes.The invention relates to a gemstone composite in which a plurality of gemstones arranged next to one another are held in a grid, and to a method for producing a gemstone composite.

Eine Vielzahl von Schmucksteinen, wie facettierten Glassteinen, wurden bisher meist in der Weise verbunden, daß die Schmucksteine mit Bohrungen versehen wurden und durch die Bohrungen jeweils zwei benachbarte Schmucksteine mittels Metalldraht aneinander gehängt wurden. Eine solche Anordnung ist kostenintensiv. Die Bohrungen stören den ästhetischen Eindruck.A large number of gemstones, such as faceted glass stones, have so far mostly been connected in such a way that the gemstones have been provided with bores and two adjacent gemstones have been attached to one another by means of metal wire through the bores. Such an arrangement is expensive. The holes disturb the aesthetic impression.

Aus der DE-C-163 964 ist ein Schmucksteinverbund bekannt, bei dem Schmucksteine, die seitliche Nuten aufweisen in einem Gitter gehalten werden. Das Gitter ist hier aus sogenannten Rahmenstäben gebildet, wobei die Längsstäbe in die Nuten in den Steinen eingelegt werden und durch angelötete oder sonst wie befestigte Drähte oder Stege miteinander verbunden werden.From DE-C-163 964 a gemstone composite is known in which gemstones that have lateral grooves are held in a grid. The grid is formed here from so-called frame bars, the longitudinal bars being inserted into the grooves in the stones and being connected to one another by soldered or otherwise secured wires or webs.

Der Erfindung liegt die Aufgabe zugrunde, einen Schmucksteinverbund zu schaffen, wobei die Schmucksteine in einfacher und wenig arbeitsintensiver Weise verbunden werden können und der optische Eindruck nicht beeinträchtigt wird.The invention has for its object to provide a gemstone composite, the gemstones can be connected in a simple and less labor-intensive manner and the visual impression is not impaired.

Der Erfindung liegt die Erkenntnis zugrunde, daß diese Aufgabe dadurch gelöst werden kann, daß die Schmucksteine mittels schrumpffähigen Kunststoffäden verbunden werden.The invention is based on the knowledge that this object can be achieved in that the gemstones are connected by means of shrinkable plastic threads.

Gegenstand der Erfindung ist ein Schmucksteinverbund, bei dem eine Vielzahl von nebeneinander angeordneten Schmucksteinen mit seitlichen Nuten in einem Gitter gehalten werden, der dadurch gekennzeichnet ist, daß das Gitter aus Längsfäden und Querfäden gebildet ist, zumindest die Längsfäden oder die Querfäden in die seitlichen Nuten der Schmucksteine eingreifen, und die Längsfäden und Querfäden aus geschrumpftem Kunststoff bestehen.The invention relates to a gemstone composite in which a plurality of gemstones arranged next to one another are held in a lattice with lateral grooves, which is characterized in that the lattice is formed from longitudinal threads and transverse threads, at least the longitudinal threads or the transverse threads in the lateral grooves of the Engage gemstones, and the longitudinal threads and transverse threads are made of shrunk plastic.

Gegenstand der Erfindung ist ferner ein Verfahren zur Herstellung eines Schmucksteinverbundes bei dem eine Vielzahl von nebeneinander angeordneten Schmucksteinen mit seitlichen Nuten in einem Gitter gehalten werden, das dadurch gekennzeichnet ist, daß das Gitter aus Längs- und Querfäden, die aus einem schrumpfbaren Kunststoff bestehen, gebildet wird, Schmucksteine in das Gitter eingesetzt werden, danach das Gitter einer Wärmebehandlung unterzogen wird, wobei das Gitter schrumpft und zumindest die Längsfäden oder die Querfäden in die Nuten der Schmucksteine einschnappen.The invention further relates to a method for producing a gemstone composite in which a plurality of gemstones arranged next to one another are held with lateral grooves in a lattice, which is characterized in that the lattice is formed from longitudinal and transverse threads which consist of a shrinkable plastic is used, gemstones are inserted into the lattice, then the lattice is subjected to a heat treatment, the lattice shrinking and at least the longitudinal threads or the transverse threads snapping into the grooves of the gemstones.

Vorzugsweise werden Kunststoffäden aus geschrumpftem thermoplastischem Kunststoff eingesetzt. Die Längsund die Querfäden des Gitters werden vorzugsweise an den Kreuzungspunkten miteinander verschweißt.Plastic threads made of shrunk thermoplastic are preferably used. The longitudinal and transverse threads of the grid are preferably welded to one another at the crossing points.

Der Schmucksteinverbund kann einreihig sein. Er eignet sich für die verschiedensten Dekorationszwecke. Eine solche Anordnung ist auch für Schmuck, beispielsweise für Armbänder, geeignet.The gem stone composite can be single-row. It is suitable for a wide variety of decorative purposes. Such an arrangement is also suitable for jewelry, for example for bracelets.

Es kommt aber auch eine mehrreihige bzw. flächenförmige Ausgestaltung in Betracht. Eine solche Anordnung kann zur Flächendekoration und insbesondere auch in der Beleuchtungsindustrie Anwendung finden.However, a multi-row or sheet-like configuration can also be considered. Such an arrangement can be used for surface decoration and in particular also in the lighting industry.

Der Begriff "Schmuckstein" wird hier in seiner allgemeinsten Form verstanden und umfaßt alle Arten von Schmucksteinen und bezieht sich insbesondere auf facettierte Glasschmucksteine. Die Form der Schmucksteine kann vielfältig sein, beispielsweise quadratisch, rechteckig, achteckig, rund oder oval. Auch die Größe der Schmucksteine ist in weiten Grenzen variabel, beispielsweise zwischen 5 und 100 mm. Die Schmucksteine können verschiedenst gefärbt sein. Sie können die verschiedensten Schliffe aufweisen.The term "gemstone" is understood here in its most general form and encompasses all types of gemstones and relates in particular to faceted glass gemstones. The shape of the gemstones can be varied, for example square, rectangular, octagonal, round or oval. The size of the gemstones is also variable within wide limits, for example between 5 and 100 mm. The gemstones can be colored in different ways. They can have a wide variety of cuts.

Die Schmucksteine haben seitlich Nuten zur Aufnahme der Kunststoffäden. Die Tiefe und Breite der Nuten kann beispielsweise zwischen 0,5 und 5 mm betragen. Die Nuten werden dem Durchmesser der Kunststoffäden angepaßt. Die Stärke der Kunststoffäden richtet sich nach der Größe der Schmucksteine und den Zugfähigkeitserfordernissen.The gemstones have grooves on the side to accommodate the plastic threads. The depth and width of the grooves can be, for example, between 0.5 and 5 mm. The grooves are adapted to the diameter of the plastic threads. The strength of the plastic threads depends on the size of the gemstones and the traction requirements.

Nuten können nur auf zwei parallel liegenden Seitenflächen zur Aufnahme der Längs- oder der Querfäden vorgesehen sein. Alternativ können auf allen vier Seiten des Schmucksteins Nuten vorgesehen sein, um sowohl die Längs- als auch die Querfäden aufzunehmen.Grooves can only be provided on two parallel side surfaces for receiving the longitudinal or transverse threads. Alternatively, on all four sides of the gemstone grooves can be provided to accommodate both the longitudinal and the transverse threads.

Die Erfindung wird anhand der Zeichnung, die beispielhafte Ausführungsformen zeigt, näher erläutert.The invention is explained in more detail with reference to the drawing, which shows exemplary embodiments.

Es zeigen:

  • Figur 1 einen einreihigen Schmucksteinverbund in Draufsicht und
  • Figur 2 einen flächenförmigen Schmucksteinverbund in Draufsicht.
Show it:
  • Figure 1 is a single row gem stone composite in plan view and
  • Figure 2 is a planar gem stone composite in plan view.

Aus Figur 1 ist zu ersehen, daß die rechteckigen Schmucksteine 2 durch ein Gitter 3 aus Längsfäden 4 und Querfäden 5 gehalten werden. Die Längsfäden 4 sind in Längsnuten 5 angeordnet, während die Querfäden 5 neben dem Schmuckstein 2 verlaufen. Es kommt alternativ in Betracht, auch die Querfäden 5 in nicht gezeigten Quernuten 7 anzuordnen. Als weitere Alternative können nur die Querfäden 5 in Quernuten 7 angeordnet sein, und die Längsfäden 4 seitlich an den Schmucksteinen 2 geführt werden.From Figure 1 it can be seen that the rectangular gems 2 are held by a grid 3 of longitudinal threads 4 and 5 transverse threads. The longitudinal threads 4 are arranged in longitudinal grooves 5, while the transverse threads 5 run next to the gem stone 2. Alternatively, it is also possible to arrange the transverse threads 5 in transverse grooves 7, not shown. As a further alternative, only the transverse threads 5 can be arranged in transverse grooves 7, and the longitudinal threads 4 can be guided laterally on the gemstones 2.

Vorzugsweise sind die Längsfäden 4 mit den Querfäden 5 an den Kreuzungspunkten 9 verschweißt. Es kommt aber auch in Betracht, das Gitter 3 durch Pressen oder Stanzen einstückig herzustellen oder die Quer- und Längsfäden in geeigneter Weise zu verkleben.The longitudinal threads 4 are preferably welded to the transverse threads 5 at the crossing points 9. However, it is also possible to manufacture the grid 3 in one piece by pressing or punching or to glue the transverse and longitudinal threads in a suitable manner.

Als Kunststoffäden werden solche aus schrumpffähigem Kunststoff verwendet. Das Gitter wird so dimensioniert, daß die Schmucksteine leicht einsetzbar sind. Die Kunststoffäden schnappen in die seitlichen Nuten ein, wobei es, um ein Durchfallen zu verhindern, ausreicht, daß nur entweder die Längsfäden oder die Querfäden in Nuten zu liegen kommen. Aus ästhetischen Gründen kann es aber vorteilhaft sein, sowohl die Quer- als auch die Längsfäden in Nuten verlaufen zu lassen.Those made of shrinkable plastic are used as plastic threads. The grid is dimensioned so that the gemstones are easy to use. The plastic threads snap into the lateral grooves, it being sufficient, in order to prevent falling through, that only either the longitudinal threads or the transverse threads come to lie in grooves. For aesthetic reasons, however, it can be advantageous to let both the transverse and the longitudinal threads run in grooves.

Nach dem Einsetzen der Schmucksteine in das Gitter werden die Kunststoffäden einem Schrumpfungsprozess unterworfen. Das Schrumpfen erfolgt meist durch Wärmebehandlung. Die vorzugsweise verwendeten kaltgereckten thermoplastischen Kunststoffäden ziehen sich bei der Wärmebehandlung wieder auf ihren Urzustand zusammen. Schrumpfungen von 3 bis 5 % oder auch bedeutend mehr sind leicht zu erzielen. Durch diese Schrumpfung der Kunststoffäden wird ein fester Halt der Schmucksteine im Gitter erzielt. Bevorzugte Kunststoffe, die einer Schrumpfung unterworfen werden können, sind Polyethylenterephthalat, Polyethylen, Polyvinylchlorid, Polypropylen, Polystyrol, Polyacrylnitril, Polyamid und Polycarbonat. Polyamid wird besonders bevorzugt. Unter Umständen kommen auch faserverstärkte Kunststoffe in Betracht.After inserting the gemstones into the grid, the plastic threads are subjected to a shrinking process. The shrinking is usually done by heat treatment. The cold-stretched thermoplastic synthetic threads that are preferably used contract back to their original state during the heat treatment. Shrinkages of 3 to 5% or significantly more are easy to achieve. This shrinkage of the plastic threads ensures a firm hold of the gemstones in the grid. Preferred plastics that can be subjected to shrinkage are polyethylene terephthalate, polyethylene, polyvinyl chloride, polypropylene, polystyrene, polyacrylonitrile, polyamide and polycarbonate. Polyamide is particularly preferred. Fiber-reinforced plastics may also be considered.

Gereckte bzw. verstreckte Kunststoffe werden auch wegen ihrer erhöhten Festigkeit bevorzugt.Stretched or stretched plastics are also preferred because of their increased strength.

Die geeigneten Schrumpfungstemperaturen werden je nach verwendetem Kunststoff gewählt. Beispielsweise kann die Schrumpfung bei Temperaturen zwischen 100 und 120°C durch Eintauchen in eine entsprechend heiße Flüssigkeit erzielt werden.The appropriate shrinkage temperatures are chosen depending on the plastic used. For example, the shrinkage at temperatures between 100 and 120 ° C can be achieved by immersion in a correspondingly hot liquid.

Es ist ersichtlich, daß Art und Anordnung der Schmucksteine in vielfältigster Weise erfolgen kann. Die Abstände zwischen den Schmucksteinen, deren Größe und Ausführung sind beliebig variabel.It can be seen that the type and arrangement of the gemstones can be done in many different ways. The distances between the gemstones, their size and design can be varied as required.

Je nach Anwendungszweck und daraus resultierenden Beanspruchungen können dünnere oder dickere Kunststoffäden verschiedener Festigkeit Verwendung finden. Die Durchmesser der Kunststoffäden liegen beispielsweise zwischen 0,3 und 5 mm.Depending on the application and the resulting stresses, thinner or thicker plastic threads of different strength can be used. The diameter of the plastic threads are, for example, between 0.3 and 5 mm.

Die erfindungsgemäßen Schmucksteinverbunde sind auf einfachste Weise und wirtschaftlich herzustellen und zeichnen sich bei Verwendung beispielsweise dünner durchsichtiger oder auch gefärbter Kunststoffäden durch eine besondere Ästhetik aus. Der Einsatz der Schmucksteinverbunde ist vielfältig. Durch die freien Fadenenden ist eine einfache und sichere Befestigung in vielfältiger Weise möglich.The gemstone composites according to the invention can be produced in the simplest and most economical manner and are distinguished by special aesthetics when using, for example, thin, transparent or colored plastic threads. The use of gemstone composites is diverse. The free thread ends enable simple and secure attachment in a variety of ways.

In Figur 2 ist eine flächenförmige Ausführungsform des Schmucksteinverbundes 1 gezeigt. Die einzelnen Schmucksteine 2 sind durch Längsfäden 4 und Querfäden 5, die ein Gitter 3 bilden, zusammengefaßt. Die Fäden 4 und 5 verlaufen in seitlichen (in der Draufsicht nicht gezeigten) Nuten der Schmucksteine 2. Eine solche flächige Anordnung ist für Dekorationszwecke oder insbesondere für Beleuchtungskörper besonders gut geeignet.FIG. 2 shows a flat embodiment of the gem stone composite 1. The individual gemstones 2 are combined by longitudinal threads 4 and transverse threads 5, which form a grid 3. The threads 4 and 5 run in lateral grooves (not shown in the plan view) of the gemstones 2. Such a flat arrangement is particularly well suited for decorative purposes or in particular for lighting fixtures.
