Description

La présente invention a pour objet un article de bijouterie à effets esthétiques spéciaux. Elle concerne tout particulièrement le domaine des bagues à porter au doigt et des bracelets à porter au poignet. Il peut également s'agir de boucles d'oreilles, de pendentifs, de boutons de manchettes ou encore de porte-clés. Plus généralement, l'invention concerne tout type d'article de bijouterie comprenant un anneau extérieur et un anneau intérieur disposé coaxialement à l'anneau extérieur, les deux anneaux étant capables de tourner l'un par rapport à l'autre.The present invention relates to a jewelery article with special aesthetic effects. It particularly relates to the field of finger rings and bracelets to wear on the wrist. It can also be earrings, pendants, cufflinks or keychains. More generally, the invention relates to any type of jewelery article comprising an outer ring and an inner ring disposed coaxially with the outer ring, the two rings being able to rotate relative to each other.

Une bague à porter au doigt est connue par le document de brevet US 221,728 au nom de Halsey . Cette bague se compose de deux anneaux respectivement intérieur et extérieur, l'anneau intérieur étant disposé concentriquement à l'anneau extérieur. L'anneau extérieur est monté pivotant sur l'anneau intérieur et comporte des fenêtres qui laissent voir des portions de l'anneau intérieur. En tournant l'anneau extérieur relativement à l'anneau intérieur, on voit apparaître des portions différentes de l'anneau intérieur, ce qui confère à la bague de Halsey un aspect changeant.A ring to wear on the finger is known from the patent document US 221,728 in the name of Halsey . This ring consists of two rings respectively inner and outer, the inner ring being arranged concentrically to the outer ring. The outer ring is pivotally mounted on the inner ring and has windows that show portions of the inner ring. By turning the outer ring relative to the inner ring, different portions of the inner ring appear, giving the Halsey ring a changing appearance.

Conformément à l'invention Halsey, l'anneau intérieur comporte sur son pourtour extérieur une rainure destinée à coopérer avec un téton prévu sur le pourtour intérieur de l'anneau extérieur. Lors du montage, l'anneau extérieur est glissé sur l'anneau intérieur, le téton se déformant élastiquement jusqu'à ce qu'il reprenne sa forme initiale en venant faire saillie dans la rainure de l'anneau intérieur. A ce moment là, les deux anneaux sont couplés axialement et autorisés à pivoter l'un par rapport à l'autre.According to the invention Halsey, the inner ring has on its outer periphery a groove for cooperating with a pin provided on the inner periphery of the outer ring. During assembly, the outer ring is slid over the inner ring, the stud deforming elastically until it resumes its original shape protruding into the groove of the inner ring. At this time, the two rings are axially coupled and allowed to rotate relative to each other.

L'invention de Halsey a pour mérite de procurer une bague de bijouterie dont l'aspect peut être modifié au gré des envies du porteur. En effet, l'anneau intérieur porte des motifs décoratifs différents qui peuvent être sélectionnés en amenant les fenêtres pratiquées dans l'anneau extérieur en regard du motif que l'on désire faire apparaître. Par contre, le couplage axial des deux anneaux intérieur et extérieur par le biais du téton ne garantit pas un assemblage indémontable. En effet, il suffit d'exercer une certaine force de poussée sur l'un des anneaux pour forcer le téton à se déformer à nouveau élastiquement, ce qui a pour effet que les deux anneaux se désolidarisent. Par ailleurs, lorsqu'on tourne l'anneau extérieur relativement à l'anneau intérieur, le téton se déplace en coulissant le long de la rainure, frottant contre le fond de cette dernière. Ce frottement procure au porteur un sentiment de qualité médiocre, ce qui n'est pas compatible avec un article de bijouterie auquel sont habituellement associées les notions de luxe et de qualité supérieure.The invention of Halsey has the merit of providing a jewelery ring whose appearance can be changed according to the desires of the wearer. Indeed, the inner ring carries different decorative patterns that can be selected by bringing the windows in the outer ring next to the pattern that is desired to appear. On the other hand, the axial coupling of the two inner and outer rings by means of the pin does not guarantee an unmountable assembly. Indeed, it is sufficient to exert a certain thrust force on one of the rings to force the stud to deform elastically again, which has the effect that the two rings are disengaged. Furthermore, when the outer ring is rotated relative to the inner ring, the stud moves slidably along the groove, rubbing against the bottom thereof. This friction gives the wearer a feeling of poor quality, which is not compatible with a jewelery item that is usually associated with the notions of luxury and superior quality.

Le document US 1,586,606 décrit une bague comprenant un anneau extérieur et un anneau intérieur disposé concentriquement à l'anneau extérieur, les deux anneaux intérieur et extérieur étant capables de pivoter l'un par rapport à l'autre. L'anneau extérieur comporte une fenêtre à travers laquelle peut apparaître un décor. L'anneau extérieur et l'anneau intérieur sont couplés axialement au moyen d'une première collerette qui vient de matière avec l'anneau intérieur et contre laquelle l'anneau extérieur prend appui, et d'une seconde collerette qui est fixée sur l'anneau intérieur à la suite de l'anneau extérieur par exemple par soudage.The document US 1,586,606 discloses a ring comprising an outer ring and an inner ring concentrically disposed to the outer ring, the two inner and outer rings being pivotable relative to each other. The outer ring has a window through which a decoration can appear. The outer ring and the inner ring are axially coupled by means of a first flange which is integral with the inner ring and against which the outer ring bears, and a second flange which is fixed on the outer ring. inner ring following the outer ring for example by welding.

Le document US 6,574,989 décrit une bague comprenant un anneau intérieur et un anneau extérieur couplés axialement au moyen d'une bille disposée dans un logement ménagé dans l'anneau extérieur et capable de rouler dans une gorge circulaire ménagée sur le pourtour extérieur de l'anneau intérieur.The document US6,574,989 discloses a ring comprising an inner ring and an outer ring axially coupled by means of a ball disposed in a housing formed in the outer ring and capable of rolling in a circular groove formed on the outer periphery of the inner ring.

Le document DE 200 19 378 U décrit une bague dont l'anneau intérieur se compose de deux parties complémentaires qui sont assemblées au moment du montage final.The document DE 200 19 378 U describes a ring whose inner ring consists of two complementary parts which are assembled at the time of final assembly.

Le document EP 1 410 728 décrit une bague dont l'anneau intérieur ou l'anneau extérieur est réalisé en deux parties assemblées au moment du montage final. Un seul mode de réalisation décrit une bague en deux parties seulement, à savoir un anneau intérieur et un anneau extérieur. Mais dans ce cas, l'anneau extérieur est moins large que l'anneau intérieur. Ceci est particulièrement inesthétique, notamment dû au fait que les billes sont visibles. En outre, les billes peuvent facilement s'encrasser.The document EP 1 410 728 describes a ring whose inner ring or the outer ring is made in two parts assembled at the time of final assembly. Only one embodiment describes a ring in two parts only, namely an inner ring and an outer ring. But in this case, the outer ring is narrower than the inner ring. This is particularly unsightly, especially because the beads are visible. In addition, the balls can easily become dirty.

La présente invention a pour but de remédier aux inconvénients susmentionnés ainsi qu'à d'autres encore en procurant un article de bijouterie à effets esthétiques spéciaux procurant notamment à son porteur un sentiment de grande qualité.The present invention aims to overcome the aforementioned drawbacks as well as others by providing a jewelery article with special aesthetic effects providing in particular to the wearer a sense of high quality.

A cet effet, la présente invention concerne un article de bijouterie selon la revendication 1 annexée.For this purpose, the present invention relates to a jewelery article according to claim 1 attached.

Grâce à ces caractéristiques, la présente invention procure un article de bijouterie à effets esthétiques spéciaux comprenant deux anneaux extérieur et intérieur capables de pivoter l'un par rapport à l'autre, l'anneau extérieur roulant sur l'anneau intérieur par le biais de la bille. Ce roulement se fait sans à-coup, nécessitant toujours de la part du porteur la même force, quelle que soit la position relative des deux anneaux et le sens de pivotement, ce qui confère au porteur un sentiment accru de qualité.Thanks to these features, the present invention provides a jewelery article with special aesthetic effects comprising two outer and inner rings capable of pivoting relative to each other, the outer ring rolling on the inner ring through the marble. This rolling is smooth, always requiring the same force from the wearer, regardless of the relative position of the two rings and the direction of rotation, which gives the wearer an increased sense of quality.

Selon une caractéristique complémentaire de l'invention, les moyens de couplage axial des deux anneaux intérieur et extérieur comprennent en outre au moins un pivot qui peut être indifféremment porté par l'un ou l'autre des deux anneaux intérieur et extérieur et qui circule dans une rainure circulaire ménagée dans l'anneau opposé.According to a complementary feature of the invention, the axial coupling means of the two inner and outer rings further comprise at least one pivot which can be indifferently carried by one or the other of the two inner and outer rings and which circulates in a circular groove formed in the opposite ring.

Selon une première variante, le pivot est chassé dans l'un ou l'autre des anneaux extérieur ou intérieur. Les deux anneaux intérieur et extérieur sont ainsi totalement indissociables après montage, même si l'on exerce une forte poussée axiale sur l'un ou l'autre des deux anneaux. Les risques que l'article de bijouterie s'abîme et que l'on perde l'un des deux anneaux sont ainsi totalement évités.According to a first variant, the pivot is driven into one or the other of the outer or inner rings. The two inner and outer rings are thus completely indissociable after mounting, even if one exerts a strong axial thrust on one or the other of the two rings. The risk that the jeweler's item is damaged and that one of the two rings is lost is thus totally avoided.

C'est pourquoi, selon une seconde variante de réalisation de l'invention, le pivot est fixé de façon démontable, par exemple par vissage, sur l'anneau concerné. L'article est ainsi rendu indémontable sauf par un bijoutier muni d'un outillage adapté qui pourra démonter le pivot, puis décaler légèrement les deux anneaux l'un par rapport à l'autre. Après quoi, muni par exemple d'une soufflette, le bijoutier pourra chasser les impuretés qui gênent le fonctionnement des anneaux.Therefore, according to a second embodiment of the invention, the pivot is removably fixed, for example by screwing on the ring concerned. The article is thus made unmountable except by a jeweler provided with suitable tools that can disassemble the pivot, then slightly shift the two rings relative to each other. After which, provided for example with a blow gun, the jeweler can chase the impurities that hinder the operation of the rings.

D'autres caractéristiques et avantages de la présente invention ressortiront plus clairement de la description détaillée qui suit d'un exemple de réalisation de l'article de bijouterie selon l'invention, cet exemple étant donné à titre purement illustratif et non limitatif seulement, en liaison avec le dessin annexé sur lequel :

  • les figures 1A et 1B sont des vues en perspective de la bague selon l'invention montrant les deux fenêtres de l'anneau extérieur amenées en regard de deux décors différents prévus sur l'anneau intérieur;
  • la figure 2 est une vue en perspective et en éclaté de la bague selon l'invention;
  • les figures 3 et 4 sont des vues en coupe transversale de la bague selon l'invention, la coupe de la figure 4 passant à travers un motif décoratif porté par l'anneau intérieur et une fenêtre de l'anneau extérieur;
  • les figures 5 et 6 sont des vues en perspective de l'anneau extérieur, l'anneau extérieur tel que représenté à la figure 6 étant pivoté de 180° par rapport à la figure 5, et
  • la figure 7 est une vue en perspective d'une pince pour le démontage partiel des deux anneaux.
Other features and advantages of the present invention will emerge more clearly from the following detailed description of an exemplary embodiment of the jewelery article according to the invention, this example being given for purely illustrative and nonlimiting purposes only, in connection with the appended drawing in which:
  • the Figures 1A and 1B are perspective views of the ring according to the invention showing the two windows of the outer ring brought opposite two different decorations provided on the inner ring;
  • the figure 2 is a perspective and exploded view of the ring according to the invention;
  • the Figures 3 and 4 are cross-sectional views of the ring according to the invention, the section of the figure 4 passing through a decorative motif carried by the inner ring and a window of the outer ring;
  • the Figures 5 and 6 are perspective views of the outer ring, the outer ring as shown in FIG. figure 6 being rotated 180 ° with respect to the figure 5 , and
  • the figure 7 is a perspective view of a clamp for the partial disassembly of the two rings.

La présente invention va être décrite en liaison avec une bague à porter au doigt. Il va de soi que cet exemple est donné à titre purement illustratif et non limitatif seulement, la présente invention pouvant tout aussi bien s'appliquer par exemple à un bracelet à porter au poignet ou à tout autre objet comprenant deux anneaux concentriques.The present invention will be described in connection with a ring to wear on the finger. It goes without saying that this example is given for purely illustrative and not limiting purposes only, the present invention can equally well apply for example to a bracelet to wear on the wrist or any other object comprising two concentric rings.

La bague l'invention, désignée dans son ensemble par la référence numérique générale 1, comprend pour l'essentiel un anneau extérieur 2 et un anneau intérieur 4 disposé concentriquement à l'anneau extérieur 2. Comme on le comprendra mieux à la lecture de ce qui suit, les deux anneaux extérieur 2 et intérieur 4 sont capables de pivoter l'un par rapport à l'autre.The ring of the invention, designated as a whole by the general numerical reference 1, essentially comprises an outer ring 2 and an inner ring 4 concentrically arranged on the outer ring 2. As will be better understood on reading this following, both outer ring 2 and inner 4 are able to rotate relative to each other.

L'anneau extérieur 2 comporte au moins une fenêtre 6 à travers laquelle est visible un décor 8 prévu sur le pourtour extérieur de l'anneau intérieur 4. Dans l'exemple représenté au dessin, l'anneau extérieur 2 comporte deux fenêtres 6 et 6' dont l'une 6, est par exemple en forme de coeur, et dont l'autre 6' est en forme de lettre grecque majuscule Ω. Il va de soi que ces exemples sont donnés à titre purement illustratif seulement et que le nombre et la forme des fenêtres peuvent être variés. Quant au décor 8 prévu sur le pourtour extérieur de l'anneau intérieur 4, il peut être de tout type voulu. Dans l'exemple représenté au dessin, ce décor 8 est formé d'une pluralité de diamants 10 sertis dans l'épaisseur de l'anneau intérieur 4. Mais on pourrait également envisager que ce décor 8 soit formé par une région réalisée dans un matériau d'une couleur différente de celle du reste de l'anneau, par exemple un décor 8 en or blanc ménagé en un endroit du pourtour de l'anneau intérieur 4 réalisé quant à lui en or jaune ou encore un décor émaillé 11. Le but de l'invention est, rappelons le, qu'en faisant tourner l'anneau extérieur 2 relativement à l'anneau intérieur 4, on sélectionne une région différente de l'anneau intérieur 4 visible à travers la ou les ouverture(s) ménagée(s) dans l'anneau extérieur 2 pour modifier l'aspect de l'anneau 1.The outer ring 2 has at least one window 6 through which is visible a decoration 8 provided on the outer periphery of the inner ring 4. In the example shown in the drawing, the outer ring 2 has two windows 6 and 6 one of which 6 is, for example, heart-shaped, and the other 6 'is in the form of a Greek capital letter Ω. It goes without saying that these examples are given for illustrative purposes only and that the number and shape of windows can be varied. As for the decor 8 provided on the outer periphery of the inner ring 4, it can be of any desired type. In the example shown in the drawing, this decoration 8 is formed of a plurality of diamonds 10 crimped in the thickness of the inner ring 4. But it could also be envisaged that this decoration 8 is formed by a region made of a material a color different from that of the rest of the ring, for example a decoration 8 in white gold arranged in a location around the inner ring 4 made in turn yellow gold or an enameled decoration 11. The purpose of the invention is, remember, that by rotating the outer ring 2 relative to the inner ring 4, is selected a different region of the inner ring 4 visible through the opening (s) arranged ( s) in the outer ring 2 to change the appearance of the ring 1.

Le maintien axial de l'anneau extérieur 2 relativement à l'anneau intérieur 4 est assuré par au moins une et, préférentiellement, deux billes 10 disposées dans deux logements 12 ménagés dans le pourtour extérieur de l'anneau intérieur 4. Ces deux logements 12 sont disposés sur un même diamètre D de l'anneau intérieur 4 et préférentiellement, mais non limitativement, espacés de 180° l'un de l'autre. Quant aux billes 10, elles sont préférentiellement réalisées en un matériau céramique pour éviter les problèmes de corrosion, mais d'autres matériaux tels que notamment un matériau métallique sont également envisageables.The axial retention of the outer ring 2 relative to the inner ring 4 is ensured by at least one and, preferably, two balls 10 arranged in two housings 12 formed in the outer periphery of the inner ring 4. These two housings 12 are arranged on the same diameter D of the inner ring 4 and preferably, but not exclusively, spaced 180 ° from each other. As for the balls 10, they are preferably made of a ceramic material to avoid corrosion problems, but other materials such as in particular a metal material are also conceivable.

Le montage de l'anneau 1 selon l'invention s'opère de la manière suivante. On place l'anneau extérieur 2 sur l'anneau intérieur 4 et on le fait tourner jusqu'à ce qu'une fenêtre 6 vienne en regard de l'un des logements 12. On insère alors l'une des billes 10 dans son logement 12 en la passant à travers la fenêtre 6. On tourne ensuite l'anneau extérieur 2 de 180° de manière que la fenêtre 6 se trouve en regard du second logement 12 encore inoccupé. Ce mouvement de pivotement de l'anneau extérieur 2 relativement à l'anneau intérieur 4, alors que l'une des billes 10 est déjà dans son logement 12, est rendu possible grâce au fait que ledit anneau extérieur 2 présente sur son pourtour intérieur un évidement circulaire 14 présentant une section droite en forme d'arc de cercle. En effet, on constate à l'examen des dessins que l'évidement circulaire 14 forme au-dessus de la bille 10 une voûte dont le point le plus haut est plus élevé que le sommet de la bille 10 disposée dans son logement 12. Ainsi, en tournant l'anneau extérieur 2 relativement à l'anneau intérieur 4, la bille 10 circule sous la voûte formée par l'évidement circulaire 14. Lorsque la fenêtre 6 se trouve en regard du second logement 12, on peut insérer la bille 10 correspondante dans ce logement 12.The assembly of the ring 1 according to the invention takes place in the following manner. The outer ring 2 is placed on the inner ring 4 and is rotated until a window 6 comes opposite one of the housings 12. One of the balls 10 is then inserted into its housing. 12 by passing it through the window 6. The outer ring 2 is then rotated by 180 ° so that the window 6 is opposite the second housing 12 which is still unoccupied. This pivoting movement of the outer ring 2 relative to the inner ring 4, while one of the balls 10 is already in its housing 12, is made possible by the fact that said outer ring 2 has on its inner periphery a circular recess 14 having a cross section in the form of a circular arc. Indeed, it is seen from the drawings that the circular recess 14 forms above the ball 10 a vault whose highest point is higher than the top of the ball 10 disposed in its housing 12. Thus by rotating the outer ring 2 relative to the inner ring 4, the ball 10 circulates under the arch formed by the circular recess 14. When the window 6 is opposite the second housing 12, the ball 10 can be inserted corresponding in this dwelling 12.

Une fois les deux billes 10 insérées dans leurs logements 12 respectifs, on tourne ensuite l'anneau extérieur 2 pour amener deux saignées 16 diamétralement opposées ménagées dans le pourtour intérieur dudit anneau extérieur 2 en regard de ces deux billes 10. Ces deux saignées 16 sont prévues pour permette de pousser axialement l'anneau extérieur 2 sur l'anneau intérieur 4 et faire pénétrer les deux billes 10 dans une gorge circulaire 18 ménagée dans le pourtour intérieur de l'anneau extérieur 2. Cette gorge circulaire 18 forme pour ces deux billes 10 un chemin de roulement le long duquel lesdites billes 10 vont pouvoir rouler lorsque l'on tournera l'anneau extérieur 2 relativement à l'anneau intérieur 4.Once the two balls 10 have been inserted in their respective housings 12, the outer ring 2 is then rotated to bring two diametrically opposite grooves 16 formed in the inner periphery of said outer ring 2 facing these two balls 10. These two grooves 16 are provided to allow axially pushing the outer ring 2 on the inner ring 4 and to penetrate the two balls 10 in a circular groove 18 formed in the inner periphery of the outer ring 2. This circular groove 18 forms for these two balls A raceway along which said balls 10 will be able to roll when the outer ring 2 is rotated relative to the inner ring 4.

Une fois que les saignées 16 ne sont plus à la hauteur des billes 10, l'ensemble formé par les deux anneaux extérieur 2 et intérieur 4 est indémontable. Il subsiste toutefois le risque qu'en manipulant les deux anneaux 2, 4 et en exerçant une poussée sur l'anneau extérieur 2, le porteur parvienne à ramener les deux saignées 16 au niveau des billes 10 et réussisse à dissocier les deux anneaux 2, 4 l'un de l'autre.Once the grooves 16 are no longer at the height of the balls 10, the assembly formed by the two outer rings 2 and inner 4 is unmountable. However, there remains the risk that by manipulating the two rings 2, 4 and exerting a thrust on the outer ring 2, the wearer succeeds in bringing the two grooves 16 to the level of the balls 10 and succeeds in dissociating the two rings 2, 4 each other.

C'est pourquoi, afin de les rendre indissociables, il est prévu de munir l'un des deux anneaux 2 ou 4 d'au moins un pivot 20, pivot qui circulera dans une rainure circulaire 22 ménagée dans l'anneau opposé. Dans l'exemple représenté au dessin, on a choisi de manière non limitative de percer deux trous 24 dans l'anneau intérieur 4, la rainure circulaire 22 étant quant à elle ménagée dans le pourtour intérieur de l'anneau extérieur 2. Ces deux trous 24 sont destinés à recevoir chacun par chassage un pivot 20. Une fois les pivots 20 installés, on procède avantageusement mais non limitativement à une brasure suivie d'un polissage pour les rendre invisibles.This is why, in order to make them inseparable, it is intended to provide one of the two rings 2 or 4 of at least one pivot 20 pivot which will circulate in a circular groove 22 formed in the opposite ring. In the example shown in the drawing, it has been chosen in a nonlimiting manner to drill two holes 24 in the inner ring 4, the circular groove 22 being formed in the inner periphery of the outer ring 2. These two holes 24 are intended to receive each by driving a pivot 20. Once the pivots 20 installed, it is advantageous but not limited to a solder followed by polishing to make them invisible.

Selon une variante, il est prévu de fixer les pivots de façon démontable, par exemple par vissage. La bague sera ainsi indémontable pour tous sauf pour un bijoutier qui, muni d'un outillage adéquat, pourra dévisser les pivots. Après quoi, le bijoutier pourra décaler les deux anneaux l'un par rapport à l'autre autant que le permettent les billes pour éliminer, par exemple au moyen dune soufflette, les impuretés (poussières, grains de sable ou autres) qui se seraient immiscées entre les deux anneaux et qui gêneraient leur mouvement de rotation.According to a variant, it is provided to fix the pivots removably, for example by screwing. The ring will be indémontable for all except for a jeweler who, equipped with adequate tools, can unscrew the pivots. After that, the jeweler can shift the two rings relative to each other as much as the balls allow to eliminate, for example by means of an air gun, impurities (dust, grains of sand or other) that would have interfered between the two rings and that would hinder their rotational movement.

On notera que les pivots 20 présentent un jeu latéral et un jeu radial avec la rainure circulaire 22 dans laquelle ils circulent, ceci afin d'éviter tout frottement.It will be noted that the pivots 20 have a lateral clearance and a radial clearance with the circular groove 22 in which they circulate, in order to avoid any friction.

On ménage en au moins un endroit du périmètre de la gorge circulaire 18 au moins une cavité 26 dans laquelle l'une ou l'autre des deux billes 10 peut venir se loger. Ces cavités 26 servent à indexer la position de l'anneau extérieur 2 relativement à l'anneau intérieur 4 en définissant deux positions prédéterminées stables dudit anneau extérieur 2 dans lesquelles les fenêtres 6, 6' font apparaître les décors 8 prévus sur l'anneau intérieur 4. Dans ces positions, il faudra exercer un couple un peu plus élevé pour faire sortir la bille 10 concernée de la cavité 26 et faire pivoter ledit anneau extérieur 2 relativement audit anneau intérieur 4.At least one location of the perimeter of the circular groove 18 is cleaned at least one cavity 26 in which one or the other of the two balls 10 can be housed. These cavities 26 serve to index the position of the outer ring 2 relative to the inner ring 4 by defining two stable predetermined positions of said outer ring 2 in which the windows 6, 6 'show the decorations 8 provided in the inner ring 4. In these positions, it will be necessary to exert a slightly higher torque to make the ball 10 come out of the cavity 26 and to pivot said outer ring 2 relative to said inner ring 4.

Il va de soi que la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit et que diverses modifications et variantes simples peuvent être envisagées par l'homme du métier sans sortir du cadre de l'invention tel que défini par les revendications annexées. En particulier, on peut envisager d'appliquer l'invention à la réalisation d'un bracelet à porter autour du poignet, de boucles d'oreilles, de boutons de manchettes, de porte-clés, de pendentifs et plus généralement de tout article de bijouterie comprenant un anneau extérieur et un anneau intérieur disposé concentriquement à l'anneau extérieur, les deux anneaux étant susceptibles de tourner l'un par rapport à l'autre.It goes without saying that the present invention is not limited to the embodiment which has just been described and that various modifications and simple variants can be envisaged by those skilled in the art without departing from the scope of the invention as defined by the appended claims. In particular, it is conceivable to apply the invention to the production of a bracelet to wear around the wrist, earrings, cufflinks, key rings, pendants and more generally any article of jewelry comprising an outer ring and an inner ring arranged concentrically to the outer ring, the two rings being rotatable relative to each other.

L'invention concerne également un accessoire pour le démontage de la bague 1 selon l'invention. Dans son acception la plus simple, cet accessoire comprend un plateau 28 présentant un épaulement circulaire 30 contre lequel l'anneau intérieur 4 vient en appui et dont le diamètre est ajusté à celui dudit anneau intérieur 4. Une fois la bague 1 disposée sur le plateau 28, on la coiffe d'un poinçon 32 de forme généralement cylindrique qui vient en appui par sa base circulaire 34 contre l'anneau extérieur 2 de ladite bague 1. Il suffit ensuite, par exemple au moyen d'une potence d'horloger (non représentée), de venir exercer une pression sur le poinçon 32. Cette pression va être communiquée à la bague extérieure 2 qui pourra se décaler axialement par rapport à la bague intérieure 4 maintenue en position par le plateau 28 dans la limite du déplacement autorisé par les billes 10. Dans une variante de réalisation préférée, le plateau 28 et le poinçon 32 seront fixés en regard l'un de l'autre sur les deux bras 36 d'une pince 38 articulés à pivotement en 40. Il va de soi que cet accessoire n'est utilisable que dans le cas où la bague 1 n'est pas munie d'un pivot ou est munie d'un pivot démontable.The invention also relates to an accessory for disassembly of the ring 1 according to the invention. In its simplest sense, this accessory comprises a plate 28 having a circular shoulder 30 against which the inner ring 4 bears and whose diameter is adjusted to that of said inner ring 4. Once the ring 1 disposed on the plate 28, it is capped with a punch 32 of generally cylindrical shape which bears by its circular base 34 against the outer ring 2 of said ring 1. It is then sufficient, for example by means of a watchmaker's stem ( not shown), to exert a pressure on the punch 32. This pressure will be communicated to the outer ring 2 which can shift axially relative to the inner ring 4 held in position by the plate 28 within the limit of the movement authorized by The balls 10. In a preferred embodiment, the plate 28 and the punch 32 will be fixed facing each other on the two arms 36 of a gripper 38 pivotally pivoted at 40. It goes without saying that this accessory is usable only in the case where the ring 1 is not provided with a pivot or is provided with a removable pivot.
