Description

ARTICLE DE JOAILLERIE JEWELERY ARTICLE
La présente invention se rapporte à des éléments décoratifs mobiles destinés à être mis en rotation et en translation dans des articles de bijouterie notamment des bagues et pendentifs, ainsi que dans des articles utilitaires décorés par des éléments décoratifs mobiles, notamment des montres, des montures de lunettes, ou des articles de maroquinerie de luxe. The present invention relates to mobile decorative elements intended to be set in rotation and in translation in articles of jewelry, in particular rings and pendants, as well as in utilitarian articles decorated by mobile decorative elements, in particular watches, glasses, or luxury leather goods.
La recherche de la mobilité d’éléments décoratifs dans une pièce d'horlogerie ou de bijouterie, quand son utilisateur fait un mouvement et la fait bouger offre un effet esthétique fort et donne un attrait visuel supplémentaire à la pièce d'horlogerie ou de bijouterie la mettant davantage en valeur. Il est connu de disposer, autour du cadran d'une pièce d'horlogerie, voire au-dessus de ce dernier, des éléments de joaillerie, tels que des pierres, ou encore des pierres montées dans des cabochons, qui disposent d'au moins un degré de liberté, dans un canal ou un espace fermé dans lequel ces éléments de joaillerie sont mobiles. The search for the mobility of decorative elements in a timepiece or piece of jewelry, when its user makes a movement and causes it to move, offers a strong aesthetic effect and gives additional visual appeal to the timepiece or piece of jewelry. emphasizing more. It is known to arrange, around the dial of a timepiece, or even above the latter, elements of jewelry, such as stones, or even stones mounted in cabochons, which have at least a degree of freedom, in a channel or a closed space in which these jewelry elements are mobile.
Par ailleurs, des pierres précieuses ou semi-précieuses ont été intégré dans un liquide. US1730257A décrit un perfectionnement d'une gemme composite du type comprenant un groupe d'une multiplicité de petites gemmes immergées et mobiles dans un liquide sensiblement transparent dans un logement sensiblement transparent dans lequel le liquide espace les petites gemmes lorsqu'elles sont mises en mouvement dans celui-ci. Le perfectionnement consiste en une pluralité de pièces d'espacement sensiblement transparentes entremêlées avec les petites gemmes et mobiles dans le liquide et ayant la propriété par rapport au liquide qui les rend sensiblement indiscernable optiquement lorsqu'elles sont dans le liquide. In addition, precious or semi-precious stones have been integrated into a liquid. US1730257A describes an improvement of a composite gem of the type comprising a group of a multiplicity of small gems immersed and mobile in a substantially transparent liquid in a substantially transparent housing in which the liquid spaces the small gems when they are set in motion in this one. The improvement consists of a plurality of substantially transparent spacers intermingled with the small gems and movable in liquid and having the property with respect to liquid that renders them substantially optically indistinguishable when in liquid.
La demanderesse qui possède une grande expertise dans la mise en oeuvre d’article comportant des éléments décoratifs mobiles cherche à obtenir un tout autre effet technique. The plaintiff, who has great expertise in the implementation of articles comprising movable decorative elements, seeks to obtain a completely different technical effect.
Le but de la présente invention est de proposer un article de joaillerie comportant une pierre précieuse ou semi-précieuse agencée dans une pièce mobile pour constituer un élément décoratif mobile dans un liquide de manière à ce que le déplacement des éléments décoratifs mobiles et l’effet spinning soient ralentis de manière à visualiser ces déplacements au ralenti, comme un effet ralenti vidéo. Conformément à l’invention, un article de joaillerie comporte au moins une paroi transparente formant un logement agencé pour recevoir au moins une pierre précieuse ou semi-précieuse immergée et mobile dans un liquide sensiblement transparent dans le logement et au moins une pièce mobile dans le liquide et ayant le même indice de réfraction que le liquide, la pièce mobile immergée dans le liquide étant sensiblement indiscernable optiquement. Le logement est délimité par deux parois dont les faces internes sont de préférence parallèles l'une à l'autre. La pierre est insérée dans la pièce pour former un élément décoratif mobile, la pièce mobile immergée dans le liquide étant sensiblement indiscernable optiquement et comportant un axe de révolution et deux surfaces de guidage adjacentes respectivement aux faces internes et permettant audit élément décoratif mobile de se déplacer librement en translation et en rotation dans le liquide autour dudit axe de révolution à l'intérieur du logement. The object of the present invention is to propose an article of jewelery comprising a precious or semi-precious stone arranged in a mobile part to constitute a mobile decorative element in a liquid in such a way that the movement of the mobile decorative elements and the effect spinning are slowed down in order to visualize these movements in slow motion, like a video slow motion effect. According to the invention, an article of jewelery comprises at least one transparent wall forming a housing arranged to receive at least one precious or semi-precious stone immersed and mobile in a substantially transparent liquid in the housing and at least one mobile part in the liquid and having the same refractive index as the liquid, the moving part immersed in the liquid being substantially optically indistinguishable. The housing is delimited by two walls whose internal faces are preferably parallel to each other. The stone is inserted into the part to form a movable decorative element, the movable part immersed in the liquid being substantially optically indistinguishable and comprising an axis of revolution and two guide surfaces adjacent respectively to the internal faces and allowing said movable decorative element to move freely in translation and in rotation in the liquid around said axis of revolution inside the housing.
Grâce à la présente invention, l’élément décoratif mobile agencé un liquide permet de créer un effet spécial de manière à ce que le déplacement des éléments décoratifs mobiles et l’effet spinning soient ralentis de manière à visualiser ces déplacements au ralenti, comme un effet ralenti vidéo qui consiste à filmer en accélérant la cadence de prise de vues pour que le mouvement restitué soit ralenti à la projection. Thanks to the present invention, the mobile decorative element arranged with a liquid makes it possible to create a special effect so that the movement of the mobile decorative elements and the spinning effect are slowed down so as to visualize these movements in slow motion, as an effect slow motion video which consists of filming by accelerating the frame rate so that the movement reproduced is slowed down on projection.
Dans une forme d’exécution, la pierre est insérée dans une pièce mobile formant douille entourant la pierre. In one embodiment, the stone is inserted into a moving part forming a socket surrounding the stone.
Afin d’être invisible chaque espace entre la partie interne de la pièce mobile et la pierre est rempli par le liquide. In order to be invisible, each space between the internal part of the moving part and the stone is filled with the liquid.
Dans une forme d’exécution, la pièce mobile est agencée pour recevoir une pluralité de pierres. Selon cette forme d’exécution, c’est un ensemble de pierres qui se déplace et tourne sur lui-même. In one embodiment, the moving part is arranged to receive a plurality of stones. According to this form of execution, it is a set of stones that moves and turns on itself.
Dans cette forme d’exécution, les pierres ont des densités différentes et sont agencées de manière à orienter les déplacements de la pièce mobile. In this embodiment, the stones have different densities and are arranged so as to orient the movements of the moving part.
Dans une forme d’exécution, la pièce mobile a un coefficient de traînée (Cx) dans le liquide qui détermine le déplacement de l’élément décoratif mobile. De manière à accélérer la rotation ralentie de l’élément décoratif mobile, la pièce mobile comporte des ailettes agencées sur son pourtour périphérique. La douille comporte des ailettes pour favoriser une rotation (spinning effect) lors de son déplacement par translation alors que l’effet de l’élément décoratif mobile dans le liquide est globalement de ralentir cet effet spinning. In one embodiment, the movable part has a drag coefficient (Cx) in the liquid which determines the displacement of the movable decorative element. In order to accelerate the slowed rotation of the movable decorative element, the movable part comprises fins arranged on its peripheral periphery. The sleeve has fins to promote rotation (spinning effect) during its movement by translation, whereas the effect of the decorative element which is mobile in the liquid is overall to slow down this spinning effect.
Pour amplifier l’effet optique, l’élément décoratif mobile peut être agencé pour se déplacer dans un couloir ou selon un chemin défini par des protubérances ou des creusures agencées sur au moins une desdites parois. Les parois créées par ces protubérances ou ces creusures peuvent être rendues invisibles dans le liquide ce qui rend l’effet encore plus spectaculaire dans la mesure où l’élément décoratif ne peut sortir de son périmètre ou suivre un autre chemin que celui défini sans que le porteur ne visualise les couloirs ou le chemin rendus invisibles. Par exemple, les protubérances ou les creusures peuvent être en verre, le liquide en glycérine, et la glace d’une desdites deux parois en saphir. Dans cette forme d’exécution, l’élément décoratif mobile ne se déplace ainsi que dans un périmètre restreint alors qu’en apparence, il pourrait se déplacer dans tout le logement. To amplify the optical effect, the mobile decorative element can be arranged to move in a corridor or along a path defined by protuberances or hollows arranged on at least one of said walls. The walls created by these protuberances or these hollows can be made invisible in the liquid, which makes the effect even more spectacular insofar as the decorative element cannot leave its perimeter or follow a path other than that defined without the wearer does not visualize the corridors or the path made invisible. For example, the protrusions or hollows can be made of glass, the liquid of glycerin, and the crystal of one of said two walls of sapphire. In this form of execution, the movable decorative element thus moves only within a restricted perimeter whereas, in appearance, it could move throughout the housing.
Dans une autre forme d’exécution, la pierre est maintenue dans la pièce par une pluralité de bras qui s’étendent au-dessus d’un corps de la pièce et qui viennent sertir la pierre, ces bras laissant entre eux et au-dessus du corps de la pièce des ouvertures latérales permettant aux flancs de la pierre, entre les bras, d’être en contact direct avec le liquide et la surface de guidage est constituée par les extrémités libres des bras sous forme de zones de contacts séparées espacés les unes des autres autour de la périphérie de la face externe ouverte de la pièce. In another embodiment, the stone is held in the piece by a plurality of arms which extend above a body of the piece and which crimp the stone, these arms leaving between them and above of the body of the part lateral openings allowing the sides of the stone, between the arms, to be in direct contact with the liquid and the guiding surface is constituted by the free ends of the arms in the form of separate contact zones spaced apart each other around the periphery of the open outer face of the part.
Dans une forme d’exécution, l’élément décoratif peut être constitué d’un cylindre creux sans fond et d’une pierre. In one embodiment, the decorative element may consist of a bottomless hollow cylinder and a stone.
La pierre peut être une pierre précieuse, notamment un diamant ou une pierre semi-précieuse. The stone may be a precious stone, in particular a diamond or a semi-precious stone.
Les éléments décoratifs mobile sont constitués d’une pierre précieuse ou semi- précieuse et de la pièce dont la forme est correspondante, par exemple cylindrique, ovale, carrée, triangle ou asymétrique. Dans une forme d’exécution, le jeu entre la hauteur de l’élément décoratif mobile et les faces internes opposées des parois est de 0.05 à 0.3mm et de préférence de 0.05 à 0.1 mm. Mobile decorative elements consist of a precious or semi-precious stone and the piece whose shape is corresponding, for example cylindrical, oval, square, triangle or asymmetrical. In one embodiment, the play between the height of the mobile decorative element and the opposite internal faces of the walls is from 0.05 to 0.3 mm and preferably from 0.05 to 0.1 mm.
Dans une forme d’exécution, les faces internes parallèles des parois sont plates mais dans une variante, les faces internes parallèles des parois sont bombées. In one embodiment, the parallel internal faces of the walls are flat but in a variant, the parallel internal faces of the walls are curved.
L’article décoratif de la présente invention peut être sous forme d’une montre ; d’un instrument d’écriture ; d’un bijou ; d’une monture de lunettes ; ou d’un article de maroquinerie. The decorative article of the present invention can be in the form of a watch; a writing instrument; a jewel; a spectacle frame; or an article of leather goods.

Comme illustré à la figure 1, une montre représentée en coupe comporte un mouvement muni d'un cadran, logé dans un boîtier comprenant une carrure fermée, d'une part par un fond, et d'autre part par une glace 1. Une seconde glace 2 est disposée entre la glace 1 et un cadran. As illustrated in FIG. 1, a watch shown in cross-section comprises a movement fitted with a dial, housed in a case comprising a middle part closed, on the one hand by a back cover, and on the other hand by a crystal 1. A second crystal 2 is arranged between crystal 1 and a dial.
Dans cet exemple, les faces internes respectives de chaque glace 1 et 2 sont appliquées contre une portée de la face interne de parties constitutives d’une boite de montre, ménageant entre elles un espace libre de hauteur déterminée et remplie d’un liquide 5. Dans cet exemple, les faces internes respectives des glaces 1 , 2 sont rigoureusement plates. Dans une variante non illustrée, les faces internes respectives des glaces 1 , 2 peuvent présenter un léger bombage formé par un ou plusieurs rayons de courbures, autour d'un ou de plusieurs centre ou axes de courbure, notamment selon des plans de coupe différents selon EP0965071. Dans ce cas, les courbures respectives données à ces deux faces internes 1 , 2 sont rigoureusement identiques les unes par rapport aux autres, afin que la hauteur de l’espace libre formé entre elles demeurent constante. In this example, the respective internal faces of each glass 1 and 2 are applied against a bearing surface of the internal face of parts constituting a box of shows, leaving between them a free space of determined height and filled with a liquid 5. In this example, the respective inner faces of the ice 1, 2 are strictly flat. In a variant not shown, the respective internal faces of the crystals 1, 2 may have a slight curvature formed by one or more radii of curvature, around one or more centers or axes of curvature, in particular according to different cutting planes according to EP0965071. In this case, the respective curvatures given to these two internal faces 1, 2 are strictly identical with respect to each other, so that the height of the free space formed between them remains constant.
De préférence, la glace de montre 1 comprend également un dispositif (non illustré) de compensation de la dilatation thermique du liquide 5 afin de compenser les variations de volume du liquide liées à la température. Ce dispositif peut prendre différentes formes, comme une membrane souple telle qu'exposée dans la demande de brevet WO 2015/150910. Preferably, the watch crystal 1 also comprises a device (not shown) for compensating for the thermal expansion of the liquid 5 in order to compensate for the variations in volume of the liquid linked to the temperature. This device can take different forms, such as a flexible membrane as disclosed in patent application WO 2015/150910.
Ainsi, comme visible à la figure 1 , la montre comporte donc deux parois transparentes 1 , 2 formant un logement 3 agencé pour recevoir quatre éléments décoratifs mobiles 4, 6 immergées et mobiles dans le liquide 5 sensiblement transparent dans le logement 3. Chaque élément décoratif mobile 4, 6 comporte une douille 6 ayant sensiblement le même indice de réfraction que le liquide 5, la douille 6 immergée dans le liquide 5 étant sensiblement indiscernable optiquement. Dans cet exemple, la douille est en verre et le liquide est de la glycérine. D’autres combinaisons sont également possibles. Le logement 3 est donc délimité par les deux parois 1 , 2 transparentes dont les faces internes 1a, 2a (voir figure 2) sont parallèles l'une à l'autre. La douille 6 immergée dans le liquide 5 est sensiblement indiscernable optiquement et comporte un axe de révolution et deux surfaces de guidage 6a, 6b adjacentes respectivement aux faces internes et permettant à chacun des quatre éléments décoratifs mobiles 4, 6 de se déplacer librement en translation et en rotation dans le liquide autour de l’axe de révolution à l'intérieur du logement 3. Thus, as visible in Figure 1, the watch therefore comprises two transparent walls 1, 2 forming a housing 3 arranged to receive four movable decorative elements 4, 6 immersed and movable in the substantially transparent liquid 5 in the housing 3. Each decorative element mobile 4, 6 comprises a sleeve 6 having substantially the same refractive index as the liquid 5, the sleeve 6 immersed in the liquid 5 being substantially optically indistinguishable. In this example, the bowl is glass and the liquid is glycerine. Other combinations are also possible. The housing 3 is therefore delimited by the two transparent walls 1, 2 whose internal faces 1a, 2a (see FIG. 2) are parallel to each other. The sleeve 6 immersed in the liquid 5 is substantially optically indistinguishable and comprises an axis of revolution and two guide surfaces 6a, 6b respectively adjacent to the internal faces and allowing each of the four movable decorative elements 4, 6 to move freely in translation and in rotation in the liquid around the axis of revolution inside the housing 3.
Ainsi, les éléments décoratifs mobiles dans le liquide permettent de créer un effet ralenti lors de leur rotation et leur déplacement. Comme illustré à la figure 2, afin de rendre la douille complètement invisible, il faut du liquide dans chaque espace entre la partie interne 6c de la douille 6 et la pierre 4. Dans une variante non illustrée, une ouverture dans la douille peut permettre au liquide de remplir l’espace entre la douille et la pierre. Dans encore une autre variante non illustrée, il est possible d’éviter d’avoir du liquide dans la douille en associant une douille et une pierre dans lesquelles l’intérieur de la douille épouse parfaitement la forme du diamant. Thus, the mobile decorative elements in the liquid make it possible to create a slowed-down effect during their rotation and movement. As illustrated in Figure 2, in order to make the sleeve completely invisible, liquid is required in each space between the internal part 6c of the sleeve 6 and the stone 4. In a variant not illustrated, an opening in the sleeve can allow the liquid to fill the space between the socket and the stone. In yet another variant not shown, it is possible to avoid having liquid in the sleeve by combining a sleeve and a stone in which the inside of the sleeve perfectly matches the shape of the diamond.
Dans l’exemple illustré aux figures 3a et 3b, la douille 6 est sous forme d’une bille. Dans l’exemple de la figure 3a, la partie interne de la bille épouse le diamant 4 et la bille est par exemple coulée ou moulée. Dans l’exemple de la figure 3b, la bille est pleine de liquide. In the example illustrated in Figures 3a and 3b, the sleeve 6 is in the form of a ball. In the example of Figure 3a, the internal part of the ball marries the diamond 4 and the ball is for example cast or molded. In the example of figure 3b, the ball is full of liquid.
Dans l’exemple illustré à la figure 4, la douille 6 est agencée pour recevoir une pluralité de pierres 4. Le fond de la douille 6 est bombé. In the example illustrated in Figure 4, the sleeve 6 is arranged to receive a plurality of stones 4. The bottom of the sleeve 6 is curved.
Dans l’exemple illustré à la figure 5, la douille 6 est représentée par un poisson et comprend une pluralité de pierres 4 chacune dans une douille miniature 6. Dans cet exemple, les pierres 4 ont des densités différentes et sont agencées de manière à orienter les déplacements de la douille. Ainsi, grâce à des pierres 4 de nature différente, par exemple si celles proches de la tête du poisson sont plus denses, cela favoriserait un déplacement du poisson « tête en avant » et accélérant la rotation du poisson. In the example illustrated in Figure 5, the socket 6 is represented by a fish and comprises a plurality of stones 4 each in a miniature socket 6. In this example, the stones 4 have different densities and are arranged so as to orient the movements of the socket. Thus, thanks to stones 4 of a different nature, for example if those close to the head of the fish are denser, this would favor a displacement of the fish “head forward” and accelerating the rotation of the fish.
Comme illustré à la figure 6, l’élément décoratif mobile est en forme de cylindre. D’autres formes géométriques sont également possibles. As shown in Figure 6, the movable decorative element is cylinder-shaped. Other geometric shapes are also possible.
La figure 7 représente une vue de dessus partielle d’une montre comportant trois éléments décoratifs mobiles 4, 6 de taille différente mis librement en rotation et en translation entre deux parois remplies par un liquide. Dans cet exemple, les douilles 6 sont de tailles différentes et invisibles si bien que les pierres ne peuvent se toucher procurant ainsi un effet de lévitation. Dans une version non illustrée, une pluralité des éléments décoratifs mobiles 4,6 peuvent être associés à une ou plusieurs douilles 6 ne comportant pas de diamant, faisant office d’espaceur, et de perturbateur de mouvement lorsque les éléments décoratifs mobiles 4, 6 se déplacent rendant ledit déplacement des éléments décoratifs mobiles 4, 6 encore plus spectaculaire par ces déplacements mystérieux. FIG. 7 represents a partial top view of a watch comprising three mobile decorative elements 4, 6 of different sizes set freely in rotation and in translation between two walls filled with a liquid. In this example, the sockets 6 are of different sizes and invisible so that the stones cannot touch each other, thus providing a levitation effect. In a version not shown, a plurality of mobile decorative elements 4, 6 can be associated with one or more sockets 6 not comprising a diamond, acting as a spacer, and as a movement disruptor when the mobile decorative elements 4, 6 move making said displacement of the movable decorative elements 4, 6 even more spectacular by these mysterious displacements.
La figure 8 représente une vue en coupe de deux éléments décoratifs mobiles 4, 6 comportant deux pierres 4 et mis librement en rotation et en translation entre deux parois 1 , 2 très espacées et remplies par un liquide 5. Figure 8 shows a sectional view of two movable decorative elements 4, 6 comprising two stones 4 and set freely in rotation and in translation between two walls 1, 2 very spaced apart and filled with a liquid 5.
La figure 9 représente une vue de dessus d’un élément décoratif mobile avec une pierre 4 en forme de cœur destiné à être mis en librement en rotation et en translation entre deux parois remplies par un liquide. Dans cet exemple, la douille 6 a un coefficient de traînée Cx dans le liquide qui détermine le déplacement de l’élément décoratif mobile. Ainsi, le mobile de forme peut être conçu de manière que son déplacement soit influencé par son coefficient de traînée Cx, ainsi le diamant cœur, dans sa chute s’oriente de manière préférentielle sur la pointe après avoir pivoté sur lui-même. FIG. 9 represents a top view of a mobile decorative element with a stone 4 in the shape of a heart intended to be placed in free rotation and in translation between two walls filled with a liquid. In this example, socket 6 has a drag coefficient Cx in the liquid which determines the displacement of the mobile decorative element. Thus, the shaped mobile can be designed so that its displacement is influenced by its drag coefficient Cx, thus the heart diamond, in its fall, is oriented preferentially on the tip after having pivoted on itself.
La figure 10 représente une vue de dessus partielle d’une montre comportant des éléments décoratifs mobiles 4, 6 mis librement en rotation et en translation entre deux parois remplies par un liquide et guidés par des chemins 19. Figure 10 shows a partial top view of a watch comprising movable decorative elements 4, 6 set freely in rotation and in translation between two walls filled with a liquid and guided by paths 19.
La figure 11 représente une vue de dessus partielle d’une montre comportant des éléments décoratifs mobiles 4, 6 mis librement en rotation et en translation entre deux parois remplies par un liquide et guidés par des couloirs 20. Figure 11 shows a partial top view of a watch comprising movable decorative elements 4, 6 placed freely in rotation and in translation between two walls filled with a liquid and guided by corridors 20.
Enfin, si dans les exemples précédents, les éléments décoratifs mobiles sont montés dans des supports en forme de petites douilles cylindriques dont la face externe du fond est convexe, la figure 13 représente une vue de côté d’un élément décoratif mobile comportant un anneau intermédiaire entre le fond convexe de la pièce faisant office de douille et l’extrémité de plusieurs bras 8 qui s’étendent au-delà de la face externe de la pierre 4. Cette douille très ouverte présente l’avantage de ne pas avoir à creuser la douille cylindrique de manière à ce qu’elle remplisse de liquide. Finally, if in the previous examples, the movable decorative elements are mounted in supports in the form of small cylindrical sockets whose outer face of the bottom is convex, figure 13 represents a side view of a movable decorative element comprising an intermediate ring between the convex bottom of the piece acting as a socket and the end of several arms 8 which extend beyond the external face of the stone 4. This very open socket has the advantage of not having to dig the cylindrical socket so that it fills with liquid.
Dans l’exemple illustré à la figure 14, afin de rendre la douille complètement invisible, il faut du liquide dans chaque espace entre la partie interne de la douille 6 et la pierre 4. Ainsi, une douille cylindrique sans fond permet au liquide de remplir l’espace entre la douille et la pierre. Grâce à la présente invention, chaque article de joaillerie comportant un élément décoratif mobile dans un liquide permettra de bénéficier de la beauté d’une pierre précieuse en rotation sur elle-même en donnant l’impression qu’elle pivote dans le vide et au ralenti ce qui rend encore plus spectaculaire son effet. Bien entendu, la présente invention ne se limite pas aux exemples cités et décrit et par exemple, on peut envisager différents types d’inserts dans les douilles comme par exemple le diamant, le rubis, la nacre, le métal, ... De la même manière, la pierre peut être insérer dans la douille par différentes techniques, comme par exemple, en étant chassée, frettée, coulée, collée, ... Comme mentionné précédemment, l'invention n'est pas limitée aux montres, mais est applicable à toutes sortes d'articles notamment de joaillerie tels que les bagues et les pendentifs, ainsi qu'à des lunettes, voire les stylos ou autre instrument d’écriture. On pourrait également envisager des articles à éléments décoratifs mobiles selon l'invention, associés à des articles de maroquinerie de luxe, tels que des sacs à main. De manière générale, ces éléments décoratifs mobiles dans le liquide peuvent s'appliquer à tout article utilitaire afin d'y associer un effet esthétique original. Notamment, il est possible d’inclure plusieurs éléments décoratifs de type différents dans un article pour produire un effet esthétique unique. In the example illustrated in Figure 14, in order to make the socket completely invisible, liquid is needed in each space between the internal part of the socket 6 and the stone 4. Thus, a bottomless cylindrical socket allows the liquid to fill the space between the socket and the stone. Thanks to the present invention, each article of jewelery comprising a decorative element that is mobile in a liquid will make it possible to benefit from the beauty of a precious stone rotating on itself by giving the impression that it is rotating in a vacuum and in slow motion. which makes its effect even more spectacular. Of course, the present invention is not limited to the examples cited and described and for example, one can consider different types of inserts in the sockets such as diamond, ruby, mother-of-pearl, metal, ... same way, the stone can be inserted into the sleeve by different techniques, such as, for example, by being chased, fretted, cast, glued, ... As mentioned above, the invention is not limited to watches, but is applicable all sorts of articles, in particular jewelery such as rings and pendants, as well as glasses, even pens or other writing instruments. It would also be possible to envisage articles with movable decorative elements according to the invention, associated with luxury leather goods, such as handbags. In general, these movable decorative elements in the liquid can be applied to any utilitarian article in order to associate an original aesthetic effect therewith. In particular, it is possible to include several decorative elements of different types in an article to produce a unique aesthetic effect.
