Description

Die Erfindung betrifft einen drehbaren Schmuckring mit mindestens einem als Innenring ausgebildeten Ringteil und mindestens einem als Aussenring ausgebildeten, konzentrischen Ringteil, sowie mit mindestens einem dazwischenliegenden Wälzlager zur Unterstützung der Drehbarkeit des Aussenrings um den Innenring. Als Schmuckringe gelten hier insbesondere Fingerringe aber auch Armreife und ähnliche ringförmige Schmuckstücke.The invention relates to a rotatable jewelry ring with at least one as Inner ring designed ring part and at least one designed as an outer ring concentric ring part, and at least one in between Rolling bearings to support the rotatability of the outer ring around the inner ring. As Jewelry rings apply here especially finger rings but also bracelets and the like ring-shaped jewelry.

Drehbare Schmuckringe der genannten Art sind bekannt, insbesondere Ringe, bei denen ein äusserer Ring auf einem inneren Ring drehbar gelagert ist und bei dem ein Wälzlager, insbesondere ein Kugellager, die Drehung unterstützt. Beispielsweise zeigt US 2,060,345 einen Ring mit Kugellager, dessen äusserer Ringteil mit Edelsteinen besetzt werden kann. FR 824.527 zeigt einen Armreif, der nach dem selben Prinzip mit Kugellager aufgebaut ist, wobei der äussere Ringteil mit bezifferten Flächen verschiedener Farbe belegt ist, so dass er sich für Glücksspiele eignet.Rotatable jewelry rings of the type mentioned are known, in particular rings, in which an outer ring is rotatably mounted on an inner ring and in which a rolling bearing, especially a ball bearing that supports rotation. For example shows US 2,060,345 a ring with ball bearing, the outer ring part with precious stones can be filled. FR 824.527 shows a bangle that follows the same Principle is built with ball bearings, the outer ring part with numbered areas different color is so that it is suitable for gambling.

Ferner zeigt das Gebrauchsmuster G 94 02 319.0 ein Dekorsystem mit Ausführungsformen als Ring oder Armreif, die aus einem inneren Ringteil und einem äusseren Ringteil, getrennt durch ein oder zwei Lager aus Wälzelementen, bestehen.Furthermore, the utility model G 94 02 319.0 shows a decor system with embodiments as a ring or bangle, which consists of an inner ring part and an outer Ring part, separated by one or two bearings from rolling elements.

Schliesslich zeigt CH 692016 einen drehbaren Schmuckring, bei welchem zwischen dem Aussenring und dem Innenring ein Wälzlager angeordnet ist, das als Wälzelemente zylindrische oder konische Walzen besitzt.Finally, CH 692016 shows a rotating jewelry ring on which a roller bearing is arranged between the outer ring and the inner ring, which as Rolling elements has cylindrical or conical rollers.

Gemeinsam ist den bekannten Schmuckringen mit Kugellagern das Problem, dass eine anfänglich gute Drehbarkeit sich relativ rasch verschlechtert, wenn der Ring beim Tragen an der Hand den dann meist unvermeidlichen, oft schwachen aber häufig wiederholten Schlagbeanspruchungen ausgesetzt ist, die das Tragen an der Hand normalerweise mit sich bringt und die auf den Drehring vorwiegend in Winkelbereichen einwirken, die zwischen der radialen und der axialen Richtung liegen. Dabei wurde gefunden, dass die Verwendung von zwei Kugellagern allein in der Regel noch keine signifikante Verbesserung der Schlagfestigkeit bewirkt.Common to the well-known jewelry rings with ball bearings is the problem that initially good rotatability deteriorates relatively quickly when the Ring when worn on the hand is then usually inevitable, but often weak frequently subjected to repeated impact stresses when wearing the Hand usually brings with it and that on the rotating ring mainly in angular ranges act that lie between the radial and the axial direction. It was found that the use of two ball bearings alone as a rule has not yet significantly improved the impact resistance.

Hauptaufgabe der Erfindung ist ein drehbarer Schmuckring, der als Wälzlager zwischen einem Innenring und mindestens einem leicht drehbaren konzentrischen Aussenring mindestens zwei Kugellager besitzt und eine verbesserte Schlagbeständigkeit hat. The main object of the invention is a rotatable jewelry ring, which is used as a roller bearing between an inner ring and at least one easily rotatable concentric Outer ring has at least two ball bearings and improved impact resistance Has.

Diese Aufgabe wird gemäss der Erfindung durch einen Schmuckring mit den in Anspruch 1 angegebenen Merkmalen gelöst, nämlich indem der Schmuckring bestimmte Mittel zum Schutz des Kugellagerpaares gegen Schlageinwirkungen aufweist.This object is achieved according to the invention by a jewelry ring with the Features specified in claim 1 solved, namely by the jewelry ring certain Has means to protect the pair of ball bearings against impact.

Gemäss einer ersten bevorzugten Ausführungsform des erfindungsgemässen Schmuckrings ist der Aussenring einstückig ausgebildet und mit innenseitlichen konkaven Rundkanten versehen, wobei das Kugellagerpaar am Innenring in zwei parallelen Lagerausnehmungen des Innenrings angeordnet und der Aussenring als Mittel zum Schutz des Kugellagerpaares gegen Schlageinwirkungen so bemessen ist, dass die innenseitlichen konkaven Rundkanten jeweils nur etwa ein Viertel des Umfangs der Kugeln der Kugellager umfassen.According to a first preferred embodiment of the invention Jewelry ring, the outer ring is formed in one piece and with inside concave round edges, the pair of ball bearings on the inner ring in two parallel bearing recesses of the inner ring arranged and the outer ring as The means for protecting the pair of ball bearings against impact is dimensioned in such a way that the inside concave rounded edges each only about a quarter of the circumference the balls of the ball bearings include.

Mit dem Begriff der "innenseitigen konkaven Rundkante" soll eine Innenkantenform des einstückigen Aussenrings bezeichnet werden, die mindestens annähernd der Form eines Kreisbogens von etwa 90° entspricht. Der einstückige Innenring ist somit an seinen inneren Endkanten auf dem Wälzlager abgestützt und kann durch normale Schlageinwirkungen praktisch nicht verkantet werden. Praktisch ein Viertel des Umfangs der Kugeln des Wälzlagers ist bei dieser Ausführungsform des erfindungsgemässen Drehrings von aussen sichtbar, was einen ästhetischen (Sichtbarkeit) und einen technischen Effekt (Selbstreinigung) bietet.With the term "inside concave round edge" an inner edge shape is meant of the one-piece outer ring, which are at least approximately corresponds to the shape of an arc of about 90 °. The one-piece inner ring is thus supported on its inner end edges on the roller bearing and can by normal impact effects are practically not tilted. Practically a quarter the circumference of the balls of the rolling bearing is according to the invention in this embodiment Rotating ring visible from the outside, which is an aesthetic (visibility) and has a technical effect (self-cleaning).

Gemäss einer zweiten bevorzugten Ausführungsform des erfindungsgemässen Schmuckrings ist der Innenring einstückig ausgebildet, während der Aussenring von zwei Ringteilen gebildet ist und zwischen jedem Ringteil des Aussenrings und dem Innenring je ein Kugellager und zwischen den beiden Ringteilen des Aussenrings ein drittes Kugellager angeordnet ist. Bei dieser Ausführungsform wird das vom Kugellagerpaar gebildete periphere, d.h. zwischen Zylinder-Mantelflächen von Innenring und Aussenringen angeordnete Wälzlager durch die gegenseitige Abstützung der Ringteile des Aussenrings über das dritte Kugellager gegen Schlagwirkungen geschützt.According to a second preferred embodiment of the invention Jewelry ring, the inner ring is integrally formed, while the outer ring is formed by two ring parts and between each ring part of the outer ring and a ball bearing between the inner ring and between the two ring parts of the outer ring a third ball bearing is arranged. In this embodiment peripheral formed by the pair of ball bearings, i.e. between cylinder surfaces of Rolling bearings arranged on the inner ring and outer rings due to the mutual support the ring parts of the outer ring via the third ball bearing against impact effects protected.

Gemäss einer dritten bevorzugten Ausführungsform des erfindungsgemässen Schmuckrings besitzt der Innenring an seiner Aussenseite eine umlaufende Ausnehmung, die den Aussenring mindestens teilweise umfasst, wobei je ein Kugellager vorzugsweise zwischen den annähernd radialen Seitenflächen der Ausnehmung des Innenrings und den Seitenflächen des Aussenrings angeordnet ist. According to a third preferred embodiment of the invention The inner ring has a circumferential recess on its outside, which at least partially includes the outer ring, each with a ball bearing preferably between the approximately radial side surfaces of the recess of the Inner ring and the side surfaces of the outer ring is arranged.

Diese weiter unten noch genauer beschriebene Ausführungsform der Erfindung bietet den zusätzlichen Vorteil, dass der Ring im Unterschied zu den drehbaren Schmuckringen des Standes der Technik nachträglich beim Juwelier durch Aufweitung angepasst werden kann, ohne seine Drehbarkeit zu verlieren.This embodiment of the invention described in more detail below offers the additional advantage that the ring is different from the rotatable State-of-the-art jewelry rings afterwards at the jeweler's by widening can be adjusted without losing its rotatability.

Die zur Führung und Halterung der als Wälzelemente verwendeten Kugeln dienenden Lagerführungen oder - Schalen können allgemein von teilkreisförmigen Ausnehmungen des Innenrings und des Aussenrings bzw. der Aussenringe gebildet werden um eine leichte Drehbarkeit trotz satter Passung zu ermöglichen. Ein reines Gleiten der als Wälzelemente verwendeten Kugeln auf den jeweils angrenzenden Ausnehmungen der benachbarten Ringteile ist meist nachteilig. Vorzugsweise wird die Auflagelinie jedes Lagerelements während einer Bewegung von benachbarten Auflagelinien abgelöst, was soviel wie Abrollen bedeutet.The used to guide and hold the balls as rolling elements Serving bearing guides or - shells can generally of part-circular Recesses of the inner ring and the outer ring or the outer rings are formed to allow easy rotation despite a tight fit. A pure one The balls used as rolling elements slide on the adjacent ones Recesses of the adjacent ring parts is usually disadvantageous. Preferably the bearing line of each bearing element during a movement of neighboring ones Support lines replaced, which means unrolling.

Im Folgenden wird die Erfindung anhand von bevorzugten Ausführungsbeispiele erläutert. Es zeigen:

  • Figur 1 die halbschematische Schnittdarstellung in der Axialebene einer ersten Ausführungsform des drehbaren Schmuckrings gemäss der Erfindung;
  • Figur 2 die halbschematische Schnittdarstellung in der Axialebene einer zweiten Ausführungsform des drehbaren Schmuckrings gemäss der Erfindung;

  • Figuren 3a und 3b jeweils Abwicklungen eines Ausführungsbeispiels des in Fig. 3 dargestellten Drehrings.
    • The invention is explained below on the basis of preferred exemplary embodiments. Show it:
  • 1 shows the semi-schematic sectional view in the axial plane of a first embodiment of the rotatable jewelry ring according to the invention;
  • Figure 2 shows the semi-schematic sectional view in the axial plane of a second embodiment of the rotatable jewelry ring according to the invention;
  • Figure 3 shows the semi-schematic sectional view in the axial plane of a third embodiment of the rotatable jewelry ring according to the invention and the
  • Figures 3a and 3b each develop an embodiment of the rotary ring shown in Fig. 3.

    • Der in Fig. 1 in einem halbschematischen Schnitt dargestellte Drehring 10 hat einen als Innenring ausgebildeten ersten Ringteil 11 mit einem als Aussenring ausgebildeten zweiten Ringteil 12 und einem Wälzlager 14, das von und einem ersten Kugellager 141 sowie einem zweiten Kugellager 142 für leichte Drehbarkeit gebildet wird. Als Mittel zum Schutz gegen Schlageinwirkungen dient die randseitige Abstützung des Aussenrings 12 an seinen beiden Innenkanten auf jeweils einem Kugellager 141, 142, indem die innenseitlichen konkaven Rundkanten 120a, 120b jeweils nur etwa ein Viertel des Umfangs der Kugeln der Kugellager 141, 142 umfassen. Die parallelen konkaven Rundkanten 120a, 120b bilden mit den ebenfalls parallelen kreisbogenförmigen Ausnehmungen 110a, 110b des Innenrings 11 die Führungen für die Kugeln der Kugellager 141, 142. Von aussen gesehen sind diese Kugeln also jeweils teilweise sichtbar. Mit anderen Worten liegen die Kugeln der Kugellager 141, 142 jeweils nur etwa zu drei Viertel im Drehring 10. Dadurch verringert sich die Reibung der Lagerelemente beim Verdrehen um etwa ein Viertel, wodurch die Drehbarkeit gesteigert wird. Gleichzeitig schützt die vollständig aussenrandseitige Abstützung des Aussenrings 12 die Kugellager 141, 142 gegen seitliche Schlageinwirkungen.The rotary ring 10 shown in a semi-schematic section in FIG. 1 has a first ring part 11 designed as an inner ring with one designed as an outer ring second ring part 12 and a roller bearing 14, the one and a first ball bearing 141 and a second ball bearing 142 are formed for easy rotation becomes. The edge support serves as a means of protection against impact of the outer ring 12 on its two inner edges, each on a ball bearing 141, 142 by the inside concave round edges 120a, 120b each only comprise about a quarter of the circumference of the balls of the ball bearings 141, 142. The parallel concave round edges 120a, 120b form with the likewise parallel ones circular recesses 110a, 110b of the inner ring 11, the guides for the balls of the ball bearings 141, 142. Seen from the outside, these balls are each partially visible. In other words, the balls of the ball bearings 141, 142 only about three quarters each in the rotating ring 10. This reduces the Friction of the bearing elements when turning by about a quarter, which makes them rotatable is increased. At the same time, the fully external edge support protects the outer ring 12, the ball bearings 141, 142 against lateral impact.

    Die Aussenseite des Aussenrings 12 kann in an sich bekannter Weise mit Dekorelementen, Ornamenten und/oder Edelsteinen versehen bzw. besetzt werden, die in ansprechendem Kontrast zu den beiderseits gut sichtbaren Kugellagern 141, 142 ausgebildet sein können.The outside of the outer ring 12 can be made in a manner known per se with decorative elements, Ornaments and / or gems are provided or set, the in an appealing contrast to the ball bearings 141, 142, which are clearly visible on both sides can be trained.

    Bei der in Fig. 2 in analoger Weise wie in Fig. 1 dargestellten Ausführungsform eines erfindungsgemässen Drehrings 20 besteht der Aussenring 22 aus zwei Ringteilen 221, 222. Diese sind über separate Kugellager 241, 242 des Wälzlagers 24 mit dem Innenring 21 verbunden. Als Mittel zum Schutz dieser Kugellager gegen Schlageinwirkungen ist hier ein weiteres Kugellager 243 vorhanden, über welches die beiden äusseren Teilringe 221, 222 aneinander abgestützt sind. Auf den einander zugewandten Innenseiten der Teilringe 221, 222 sind kreisbogenförmige Rillen als Führungen vorgesehen, wobei jede Rille typisch etwa 110° -150° des Umfangs der Kugeln der Kugellager 241, 242 umfasst. Auf diese Weise sind die beiden äusseren Teilringe 221, 222 um etwa ein Drittel des Durchmessers der Kugeln der Kugellager 241, 242 voneinander beabstandet und die Kugeln in diesem Bereich von aussen sichtbar. Die Sichtbarkeit der Kugeln kann auf diese Weise in weiten Grenzen den jeweiligen Wünschen für die äussere Erscheinung angepasst werden.In the embodiment shown in FIG. 2 in a manner analogous to that in FIG. 1 of a rotary ring 20 according to the invention, the outer ring 22 consists of two Ring parts 221, 222. These are via separate ball bearings 241, 242 of the roller bearing 24 connected to the inner ring 21. As a means of protecting these ball bearings against Another ball bearing 243 is present here, via which the two outer part rings 221, 222 are supported on one another. To each other facing inner sides of the partial rings 221, 222 are circular arc-shaped grooves Guides are provided, each groove typically being about 110 ° -150 ° the circumference of the Balls of the ball bearings 241, 242 comprises. In this way, the two are outside Part rings 221, 222 by about a third of the diameter of the balls of the ball bearings 241, 242 spaced apart and the balls in this area from the outside visible. The visibility of the spheres can thus be within wide limits be adapted to the respective wishes for the external appearance.

    Wie in Fig. 2 dargestellt, überragen die Aussenringteile 221, 222 die beiden Kugellager 241, 242. Dies ist jedoch keine kritische Bedingung und die Aussenringteile 221, 222 können in ähnlicher Weise, wie in Fig. 1 dargestellt, durch entsprechende Ausführung der Führungsrillen 210a, 210b als jeweils aussenrandseitige konkave Rundkanten auf den Kugellagern 241, 242 abgestützt und dadurch ebenfalls teilweise sichtbar sein.As shown in Fig. 2, the outer ring parts 221, 222 protrude the two Ball bearings 241, 242. However, this is not a critical condition and the outer ring parts 221, 222 can in a similar manner, as shown in Fig. 1, by corresponding Execution of the guide grooves 210a, 210b as concave on the outer edge in each case Round edges supported on the ball bearings 241, 242 and therefore also be partially visible.

    Eine weitere bevorzugte Ausführungsform eines erfindungsgemässen Drehrings 30 ist in Fig. 3 dargestellt, wiederum in halbschematischer Schnittansicht wie in den Figuren 1 und 2. Hierbei wird der Innenring 31 aus später noch eingehender erläuterten Gründen der Fertigung von zwei Ringteilen 311, 312 gebildet, die gemeinsam die in Fig. 3a dargestellte umlaufende Ausnehmung 300 bilden, die den Aussenring 32 mindestens teilweise umgibt. Im typischen Fall ragt der Aussenring 32 nur zu etwa 10 - 30 % seiner Dicke aus der Ausnehmung 300 des Innenrings 31 heraus, kann aber auch erheblich weiter herausragen, wenn der Aussenring 32 eine entsprechende Dicke hat und die Kugellagerführungen 321a, 321b am unteren Ende des Aussenrings liegen. Das vorzugsweise zwischen den annähernd radial verlaufenden ringförmigen Flächen 301a, 301b und 322a, 322b aus zwei Kugellagern 341, 342 gebildete Wälzlager 34 ist besonders wirksam gegen Schlageinwirkungen geschützt.Another preferred embodiment of a rotating ring according to the invention 30 is shown in Fig. 3, again in a semi-schematic sectional view like in Figures 1 and 2. Here, the inner ring 31 will be more detailed later explained reasons of the production of two ring parts 311, 312 formed together the circumferential recess 300 shown in Fig. 3a, which the Outer ring 32 at least partially surrounds. The outer ring typically protrudes 32 only about 10 - 30% of its thickness from the recess 300 of the inner ring 31 out, but can also protrude considerably further if the outer ring 32 a has corresponding thickness and the ball bearing guides 321a, 321b at the lower end of the outer ring. That is preferably between the approximately radial ones annular surfaces 301a, 301b and 322a, 322b from two ball bearings 341, 342 Rolling bearing 34 is particularly effectively protected against impact.

    Im typischen Fall hat die Ausnehmung 300 den in Fig. 3a dargestellten, annähernd rechteckig-trogförmigen Querschnitt, doch ist dies ein bevorzugtes und nicht kritisches Merkmal, da auch runde oder trapezförmige Querschnittsformen der Ausnehmung 300 möglich sind. Jedenfalls erstreckt sich die Ausnehmung 300 um den ganzen Innenring 31. Sie wird zweckmässigerweise dadurch gebildet, dass zwei entsprechend ineinander passende Teile 311, 312 zur Bildung des Innenrings 31 zusammengesetzt werden, und zwar vorzugsweise nach einer temporären Verbindung der Wälzelemente der beiden Kugellager 341, 342 mit dem Aussenring 32, d.h. an dessen umlaufenden Führungsrillen 321a, 321b, z.B. mittel eines Haftstoffes. Als Haftstoffe können Klebstoffe auf Basis von Polymeren, wie Polyvinylacetat, Acetylcellulose oder dergleichen verwendet werden, die in einem flüchtigen oder wässrigen Lösungsmittel gelöst sind und nach dem Verfestigen erneut im Lösungsmittel löslich sind, also nicht vernetzen. Es können aber auch Stärkekleber, Fette oder Wachse als Haftmittel verwendet werden, sofern eine einfache Entfernbarkeit gewährleistet ist.Typically, the recess 300 is approximately that shown in FIG. 3a rectangular trough-shaped cross-section, but this is a preferred and not Critical feature, as there are also round or trapezoidal cross-sectional shapes of the recess 300 are possible. In any case, the recess 300 extends around the whole inner ring 31. It is expediently formed by two accordingly mating parts 311, 312 assembled to form the inner ring 31 be, preferably after a temporary connection the rolling elements of the two ball bearings 341, 342 with the outer ring 32, i.e. on its circumferential guide grooves 321a, 321b, e.g. means of an adhesive. As Adhesives can be adhesives based on polymers, such as polyvinyl acetate or acetyl cellulose or the like can be used in a volatile or aqueous Solvents are dissolved and after solidification again soluble in the solvent are, so do not network. It can also be used as starch glue, fat or wax Adhesives are used, provided that they can be removed easily.

    Gemäss der Darstellung in den Fig. 3 und 3a hat die Ausnehmung 300 des Innenrings 31 eine Bodenfläche 310, die vorzugsweise von der Innenfläche 320 des Aussenrings mindestens soweit beabstandet ist, dass der einzige Kontakt zwischen dem Innenring 31 und dem Aussenring 32 über die beiden Kugellager 341, 342 besteht, die in entsprechenden Führungsrillen 302, 321 des Innenrings 31 bzw. des Aussenrings 32, vorzugsweise auch hier mit kreisbogenförmigem Querschnitt, laufen. Die Verbindung der beiden Teile 311, 312 des Innenrings 31 zur Bildung des Ausnehmung 300 ist nicht kritisch und kann mit verschiedenen bekannten Methoden einschliesslich Presspassung, Klemmpassung, Verkleben, Verlöten oder Verschweissen bewerkstelligt werden, wobei die temporäre Verbindung des Aussenrings mit den Kugeln der Lager 341, 342 entsprechend modifiziert werden sollte.According to the illustration in FIGS. 3 and 3a, the recess 300 of the Inner ring 31 has a bottom surface 310, which preferably extends from the inner surface 320 of the Outer ring is at least as far apart that the only contact between the inner ring 31 and the outer ring 32 via the two ball bearings 341, 342, the corresponding guide grooves 302, 321 of the inner ring 31 and the outer ring 32, preferably also here with an arcuate cross section. The connection of the two parts 311, 312 of the inner ring 31 to form the recess 300 is not critical and can be done using various known methods including Press fit, clamp fit, gluing, soldering or welding be accomplished, whereby the temporary connection of the outer ring with the Balls of bearings 341, 342 should be modified accordingly.

    Ein bevorzugtes Beispiel der Verbindung ist durch die in Fig. 3b gezeigte Abwicklung dargestellt. Die zapfenförmigen Vorsprünge 314 des Teilrings 311 sind auf Presspassung in die entsprechenden Ausnehmungen 315 des Innenringteils 312 bemessen. Die Verbindung kann hierbei durch einfaches Zusammenpressen der Ringteile 311, 312 bewerkstelligt werden, selbstverständlich nach vorheriger Einführung des lösbar mit den Kugeln verbundenen Aussenrings 32.A preferred example of the connection is that shown in Fig. 3b Processing shown. The peg-shaped projections 314 of the partial ring 311 are to press fit into the corresponding recesses 315 of the inner ring part 312 sized. The connection can be done by simply pressing the Ring parts 311, 312 are accomplished, of course after prior introduction of the outer ring 32 releasably connected to the balls.

    Auch bei der in Fig. 3 dargestellten Ausführungsform kann die Sichtbarkeit der Kugellager 341, 342 durch entsprechende Bemessung der Abstände zwischen Innenring 31 und Aussenring 32 modifiziert werden und auch hier können die oben erwähnten Dekorelemente an der Aussenfläche des Aussenrings 32 und/oder bei entsprechend breiter Ausführung der Ränder 318, 319 der Ausnehmung 300 auch an der Aussenseite des Innenrings angebracht werden.Visibility is also possible in the embodiment shown in FIG. 3 the ball bearing 341, 342 by appropriate dimensioning of the distances between the inner ring 31 and outer ring 32 can be modified and also here the above mentioned decorative elements on the outer surface of the outer ring 32 and / or accordingly wider design of the edges 318, 319 of the recess 300 also on the Be attached outside of the inner ring.

    Schliesslich ist es möglich, zwischen der Bodenfläche 310 der Ausnehmung 300 und der inneren Mantel läche 320 des Aussenrings ein oder zwei Kugellager anzuordnen, welche die Kugellager 341, 342 ergänzen oder diese ersetzen. Dies wird jedoch für viele Ausführungsformen weniger bevorzugt, weil dabei ein besonderer Vorteil des erfindungsgemässen Drehrings gemäss den Erläuterungen zu Fig. 3 gefährdet wird. Dieser überraschende Vorteil besteht darin, dass erfindungsgemässe Drehringe mit ganz oder teilweise versenktem Aussenring bei Anordnung der Kugellager zwischen den annähernd radial verlaufenden Flächen 301, 322 von Innenring 31 und Aussenring 32 zur Anpassung an den Finger des Trägers nachträglich, z.B. durch den Juwelier, aufgeweitet werden können, wie dies bei normalen einteiligen Ringen üblich ist, was bei Drehringen des Standes der Technik mit ihren zwischen peripheren Grenzflächen angeordneten Wälzlagern aber bisher praktisch nicht möglich war. Die Verwendung von Drehringen mit Wälzlagern in radialen Ebenen ist daher ein besonderes Merkmal dieser Ausführungsform der Erfindung.Finally, it is possible between the bottom surface 310 of the recess 300 and the inner coat Surface 320 of the outer ring to arrange one or two ball bearings, which are the ball bearings Add 341, 342 or replace them. However, this is true for many embodiments less preferred because a particular advantage of the inventive Rotating ring according to the explanations for Fig. 3 is at risk. This surprising one The advantage is that rotating rings according to the invention with all or part sunken outer ring with arrangement of the ball bearings between the approximately radially extending surfaces 301, 322 from inner ring 31 and outer ring 32 to Subsequent adjustment to the wearer's finger, e.g. expanded by the jeweler can be, as is usual with normal one-piece rings, which with Rotating rings of the prior art with their between peripheral interfaces arranged roller bearings was previously practically impossible. The usage of rotating rings with roller bearings in radial planes is therefore a special feature this embodiment of the invention.

    Häufig ist es bei allen Ausführungsformen der Erfindung gemäss den Figuren 1 und 2 zweckmässig, die Führungsrillen für die Kugellager im Innenring 11, 21 gleich tief oder etwas tiefer auszuführen, als jene im Aussenring. Bei der Ausführungsform gemäss Fig. 3 kann es hingegen zweckmässig sein, die Rillen 321a, 321b im Aussenring gleich tief oder tiefer auszuführen als die Führungen 302a, 302b des Innenrings, weil dies zur Erhöhung der Stabilität dieser "hängenden Wälzlager" dienen kann und/oder den Zusammenbau erleichtert.It is common in all embodiments of the invention according to the figures 1 and 2 expedient, the guide grooves for the ball bearings in the inner ring 11, 21st to be the same depth or a little deeper than that in the outer ring. In the embodiment 3, on the other hand, it can be expedient for the grooves 321a, 321b Execute the same depth or depth in the outer ring than the guides 302a, 302b of the Inner ring, because this will increase the stability of these "hanging rolling bearings" can and / or facilitate assembly.

    Bei erfindungsgemässen drehbaren Schmuckringen bestehen die Innen- und Aussenringe meist aus den für Ringe üblichen Edelmetallen bzw. Edelmetalllegierungen, können aber auch aus anderen Werkstoffen, z.B. Edelstahl, Titan, Silizium, Leichtmetall, Hartmetall oder keramischen Werkstoffen bestehen, z.B. solchen auf Basis von Silikaten oder von Silizium- oder Aluminiumoxid. Die Wälzelemente können aus den für die Ringe angeführten Werkstoffen bestehen, wobei sich jedoch die für die Ringe und die Wälzelemente verwendeten Werkstoffe mindestens an ihrer Aussenseite vorzugsweise sichtbar unterscheiden. Dies kann in üblicher Weise aber auch durch Beschichtung, z.B. auf galvanischem Weg oder durch Dampfablagerung im Vakuum erzielt werden. Allgemein können die Aussenringe und/oder die Innenringe mit Schmucksteinen bzw. Schmuckeinlagen oder Schmuckauflagen versehen sein, wie dies für drehbare Schmuckringe bekannt ist.
    Im Rahmen der Erfindung sind zahlreiche Modifikationen möglich und für Fachleute an Hand der obigen Erläuterungen ohne weiteres einsichtig. So können z.B. die verschiedenen Mittel zur Erhöhung der Schlagbeständigkeit miteinander kombiniert werden, etwa indem der als einteilig beschriebene Aussenring, der in einer Ausnehmung des Innenrings umlaufend angeordnet ist, aus mehreren Teilen gebildet wird, die gegebenenfalls wiederum gegeneinander über dazwischen angeordnete Kugellager aneinander abgestützt sind. Ferner kann der Schutz der hängenden Lager auch mit Ausnehmungsformen erzielt werden, welche den Aussenring noch weitgehender umfassen, als die oben erläuterte rechteckig-trogförmige Ausnehmung, etwa wenn die Ausnehmung und/oder der Aussenring rund ausgebildet sind oder die Ausnehmung sich trapezförmig nach aussen verjüngt, sofern die Rückhaltefähigkeit der Kugellager dies zulässt. Wie bereits angedeutet, kann die Aussenfläche des Aussenrings auch mit der Aussenfläche des Innenrings fluchten, oder eine gemeinsame Krümmung aufweisen. Schliesslich kann der Aussenring auch praktisch vollständig vom Innenring umschlossen sein und z.B. nur mit periodisch oder aperiodisch um den Umfang des Aussenrings verteilten Protrusionen herausragen, um durch eine entsprechende Betätigung die gewünschte Drehung des Aussenrings auszulösen.    In the case of rotatable jewelry rings according to the invention, the inner and outer rings mostly consist of the precious metals or precious metal alloys customary for rings, but can also consist of other materials, for example stainless steel, titanium, silicon, light metal, hard metal or ceramic materials, for example those based on silicates or of silicon or aluminum oxide. The rolling elements can consist of the materials listed for the rings, but the materials used for the rings and the rolling elements preferably differ visibly at least on their outside. In the usual way, however, this can also be achieved by coating, for example by galvanic means or by vapor deposition in a vacuum. In general, the outer rings and / or the inner rings can be provided with gemstones or jewelery inlays or jewelery supports, as is known for rotatable jewelery rings.
    Numerous modifications are possible within the scope of the invention and are readily apparent to those skilled in the art on the basis of the above explanations. For example, the various means of increasing the impact resistance can be combined with one another, for example by forming the outer ring, which is described in one piece and which is arranged in a recess in the inner ring, from several parts, which in turn are supported against one another by means of ball bearings arranged in between. Furthermore, the protection of the hanging bearings can also be achieved with recess shapes which encompass the outer ring even more extensively than the rectangular-trough-shaped recess explained above, for example if the recess and / or the outer ring are round or the recess tapers outward in a trapezoidal shape, if the retention capacity of the ball bearings allows this. As already indicated, the outer surface of the outer ring can also be aligned with the outer surface of the inner ring or have a common curvature. Finally, the outer ring can also be virtually completely enclosed by the inner ring and, for example, protrude only with protrusions distributed periodically or aperiodically around the circumference of the outer ring in order to trigger the desired rotation of the outer ring by appropriate actuation.
