Description

Domaine techniqueTechnical area

La présente invention concerne un système de sertissage pour un article d'horlogerie ou de joaillerie dans lequel une pierre précieuse est montée de façon à donner un effet visuel de vibration de la pierre. La présente invention concerne également un cadran de montre et une pièce d'horlogerie ou bijouterie comportant un tel système de sertissage.The present invention relates to a crimping system for a timepiece or jewelery in which a gemstone is mounted to give a visual effect of vibration of the stone. The present invention also relates to a watch face and a timepiece or jewelery including such a crimping system.

Etat de la techniqueState of the art

Les systèmes de sertissage permettre de monter un ou des pierres précieuses à un support. Lorsque la pierre est montée de manière fixe sur le support, il est difficile de voir la lumière réfléchie au travers des différentes facettes de la pierre puisque les mouvements de la pierre sont très réduits. Un tel montage n'est donc pas optimal lorsque l'on recherche un certain effet d'animation. Pour cette raison, des systèmes de sertissage comprennent des éléments ressort ou des moyens optiques afin de produire un effet d'animation.The crimping systems allow to mount one or more precious stones to a support. When the stone is fixedly mounted on the support, it is difficult to see the light reflected through the different facets of the stone since the movements of the stone are very small. Such an arrangement is therefore not optimal when looking for a certain animation effect. For this reason, crimping systems include spring elements or optical means to produce an animation effect.

Dans le brevet US6433483 , un article de bijouterie comporte des diamants étant illuminés à l'aide d'une source d'illumination. Un contrôleur contrôle la source d'illumination de sorte à varier l'intensité de la lumière émise pas la source permettant ainsi de mieux ressortir les effets optiques du diamant. Il est cependant souvent indésirable d'utiliser des dispositifs électroniques dans des pièces d'horlogerie ou bijouterie d'haute gamme.In the patent US6433483 , a jewelery item has diamonds being illuminated with an illumination source. A controller controls the illumination source so as to vary the intensity of the light emitted by the source, thus making it possible to better highlight the optical effects of the diamond. However, it is often undesirable to use electronic devices in timepieces or high-end jewelry.

Le document EP2510824 décrit un article de bijouterie comprenant une pierre précieuse fixée dans un chaton monté sur un élément pivot en matière plastique ou élastomère. Bien que l'ensemble pierre-chaton puisse se déplacer, son mouvement sur l'élément pivot ne donne pas un effet visuel de vibration de la pierre.The document EP2510824 discloses a jewelery article comprising a precious stone fixed in a kitten mounted on a pivotal element made of plastic or elastomer. Although the whole kitten stone can move, its movement on the pivot element does not give a visual effect of vibration of the stone.

Le modèle d'utilité RU100367U décrit un article de bijouterie comprenant une pierre précieuse fixée dans un chaton en forme de rondelle, cet ensemble pierre-chaton est lié à une base de l'article par un ressort cylindrique. La vibration de la pierre montée sur le ressort provoque un effet de réfraction de la lumière. La fixation des extrémités du ressort au chaton et à la base est cependant compliquée et délicate. Dans le cas de petits ressorts, requis dans le cas de pierres de faibles tailles, ces derniers peuvent se déformer d'une manière excessive lorsque la pierre se déplace par rapport à sa position initiale, péjorant le mouvement de vibration de la pierre et donc de l'esthétique de la pièce. De plus, le dimensionnement du ressort de sorte à obtenir l'effet visuel recherché le rend fragile et le ressort peut être également déformé de manière irréversible par les chocs.The utility model RU100367U describes a jewelery item comprising a gemstone set in a washer-shaped kitten, this set of stone-kitten is bonded to a base of the article by a cylindrical spring. The vibration of the stone mounted on the spring causes a refraction effect of the light. Fixing the ends of the spring to the kitten and the base is however complicated and delicate. In the case of small springs, which are required in the case of small stones, they may be excessively deformed when the stone moves from its original position, thereby disturbing the vibration movement of the stone and therefore the aesthetics of the room. In addition, the dimensioning of the spring so as to obtain the desired visual effect makes it fragile and the spring can also be irreversibly deformed by shocks.

La demande de brevet WO2012/115458 décrit un article de bijouterie comprenant un support en forme de bague ayant un secteur creux dans lequel est monté un chaton par le biais d'un ressort spiral ou conique. Les extrémités du ressort sont fixées dans des rainures pratiquées dans le support et dans le chaton respectivement, et le chaton est mis en oscillation sous l'effet d'excitations externes sur le support. Selon une forme d'exécution, une goupille est montée au travers la partie supérieure du chaton, chacune des extrémités de la goupille étant logée dans le support dans un plan parallèle au plan du ressort (le ressort étant fixé à une partie inférieure du chaton). La goupille sert à empêcher la séparation du chaton et du support au cas de chocs importants. Selon ce document, avec cette construction, la partie inférieure du chaton peut uniquement vibrer dans une direction perpendiculaire à la goupille dans le plan du ressort, et la partie supérieure du chaton reste effectivement solidaire du support.The patent application WO2012 / 115458 discloses a jewelery article comprising a ring-shaped carrier having a hollow sector in which a kitten is mounted by means of a spiral or conical spring. The ends of the spring are fixed in grooves in the support and in the kitten respectively, and the kitten is oscillated under the effect of external excitations on the support. According to one embodiment, a pin is mounted through the upper part of the kitten, each end of the pin being housed in the support in a plane parallel to the plane of the spring (the spring being attached to a lower part of the kitten) . The pin is used to prevent the separation of the kitten and the support in case of major shocks. According to this document, with this construction, the lower part of the kitten can only vibrate in a direction perpendicular to the pin in the plane of the spring, and the upper part of the kitten remains effectively secured to the support.

Bien qu'un tel article soit moins susceptible à une séparation accidentelle du chaton et/ou une déformation du ressort suite à un choc important, les oscillations du chaton sont beaucoup trop limitées par la goupille qui les amortisse d'une manière importante en permanence. Cela dénie en conséquence l'effet visuel recherché de l'article, voire la vibration ou mouvement de la pierre. De plus, même après le montage d'une pierre dans le chaton, le ressort et la goupille restent complètement visibles au porteur de l'article, ce qui affouille énormément l'esthétique de l'article de bijouterie.Although such an article is less susceptible to accidental separation of the kitten and / or deformation of the spring following a major shock, the oscillations of the kitten are much too limited by the pin that dampens them permanently. This denies accordingly the desired visual effect of the article, or the vibration or movement of the stone. In addition, even after mounting a stone in the kitten, the spring and the pin remain completely visible to the wearer of the article, which undermines enormously the aesthetics of the jewelry item.

Un but de la présente invention est de proposer un système de sertissage pour un article d'horlogerie ou de joaillerie exempt des limitations de l'état de la technique connu.An object of the present invention is to provide a crimping system for a timepiece or jewelery free of limitations of the prior art known.

Exemple(s) de mode de réalisation de l'inventionExample (s) of embodiment of the invention

Un système de sertissage 1 pour un article d'horlogerie 6 ou de joaillerie est illustré aux figures 1 et 2, selon un mode de réalisation. Le système de sertissage 1 comprend un support de sertissage 3, ou chaton, dans lequel est montée une pierre précieuse 2, telle qu'un diamant, rubis, saphir ou émeraude. On comprendra ici que l'expression "une pierre précieuse" signifie au moins une pierre précieuse 2, le support 3 pouvant supporter une pluralité de pierres précieuses 2. L'expression "pierre précieuse" peut également englober tout type de pierres, telles que les pierres fines. Un élément élastique 5 fixé au support de sertissage 3 relie de façon flexible le support de sertissage 3 à l'article 6. L'élément élastique 5 s'étend axialement entre le support de sertissage 3 et l'article 6.A crimping system 1 for a timepiece 6 or jewelery is illustrated in FIGS. figures 1 and 2 according to one embodiment. The crimping system 1 comprises a crimping support 3, or kitten, in which is mounted a gemstone 2, such as a diamond, ruby, sapphire or emerald. It will be understood here that the expression "a gemstone" means at least one gemstone 2, the support 3 being able to support a plurality of precious stones 2. The expression "gemstone" can also include any type of stone, such as fine stones. An elastic element 5 fixed to the crimping support 3 flexibly connects the crimping support 3 to the article 6. The elastic element 5 extends axially between the crimping support 3 and the article 6.

Dans cet arrangement, la pierre 2 peut osciller ou vibrer sur l'élément élastique 5 suite à un mouvement de l'article 6 (autrement dit, de sorte à ce que le support de sertissage, et donc la pierre, puisse osciller ou vibrer sur l'élément élastique 5 suite à un mouvement de l'article 6). Par exemple, lors d'un choc ou d'un mouvement brusque de l'article d'horlogerie ou de joaillerie 6 comportant le système de sertissage 1, l'extrémité 17 de l'élément élastique 5 fixée sur l'article 6 reste fixe, tandis que le reste de l'élément élastique 5 se déforme élastiquement sous l'effet de l'accélération de la masse de la pierre 2 et du support de sertissage 3. La raideur de l'élément élastique 5, la masse de la pierre 2 et du support de sertissage 3, ainsi que l'intensité du choc sont les principaux facteurs définissant l'amplitude des vibrations (ou oscillations) de la pierre 2. L'oscillation de la pierre 2 se fait selon un mouvement radial par rapport à un axe de symétrie 15 et un mouvement axial par rapport à ce même axe 15.In this arrangement, the stone 2 can oscillate or vibrate on the elastic member 5 following a movement of the article 6 (that is, so that the crimping support, and thus the stone, can oscillate or vibrate on the elastic element 5 following a movement of the article 6). For example, during a shock or a sudden movement of the timepiece or jewelery 6 comprising the crimping system 1, the end 17 of the elastic element 5 fixed on the article 6 remains fixed while the rest of the elastic element 5 deforms elastically under the effect of the acceleration of the mass of the stone 2 and the crimping support 3. The stiffness of the elastic element 5, the mass of the stone 2 and the crimping support 3, as well as the intensity of the shock are the main factors defining the amplitude of the vibrations (or oscillations) of the stone 2. The oscillation of the stone 2 is in a radial movement with respect to an axis of symmetry 15 and an axial movement with respect to this same axis 15.

Comme le système de sertissage 1 est destiné à un article d'horlogerie 6 ou de joaillerie, il doit être arrangé pour pouvoir créer une animation, par exemple sur un cadran de montre, sur la base d'une vibration de la pierre. Autrement dit, le système de sertissage 1 doit être configuré pour que la vibration de la pierre soit visible. La vibration doit également être pérenne dans le temps et dans son environnement d'utilisation. D'autre part, de manière à loger le système de sertissage 1, par exemple, entre le cadran et la glace de la montre, sur une lunette, un bijou, son encombrement doit être minimal et les dimensions du système de sertissage 1 devront être réduites.As the crimping system 1 is intended for a timepiece 6 or jewelry, it must be arranged to be able to create an animation, for example on a watch dial, based on a vibration of the stone. In other words, the crimping system 1 must be configured so that the vibration of the stone is visible. The vibration must also be durable in time and in its environment of use. On the other hand, so as to accommodate the crimping system 1, for example, between the dial and the ice of the watch, on a bezel, a jewel, its size must be minimal and the dimensions of the crimping system 1 must be reduced.

La vibration de la pierre 2, selon un mouvement axial et/ou radial par rapport à l'axe de symétrie 15, sera visible dans le cas où la fréquence d'oscillation de celle-ci est adaptée à la persistance rétinienne. Cette fréquence d'oscillation est de préférence comprise entre 1 Hz et 30 Hz.The vibration of the stone 2, in an axial and / or radial movement with respect to the axis of symmetry 15, will be visible in the case where the oscillation frequency thereof is adapted to the retinal persistence. This oscillation frequency is preferably between 1 Hz and 30 Hz.

Dans une forme d'exécution illustrée à la figure 1, l'élément élastique comprend un ressort de torsion 5 formé d'un ressort à développante hélicoïdale, ci-après appelé " ressort hélicoïdal" comprenant un enroulement 50 d'une ou de plusieurs spires 10. Une portion proximale 13 s'étend à partir de l'enroulement 50 et est fixée sur le support de sertissage 3. Une portion distale 17 s'étend à partir de l'enroulement 50 et est destinée à coopérer avec l'article 6. A l'état de repos, c'est-à-dire en absence de vibration, le ressort de torsion 5 présente une configuration dans laquelle les portions proximale 13 et distale 17 s'étendent de manière sensiblement parallèle à l'axe de symétrie 15 (la portion 13 et l'axe 15 sont même sensiblement confondus) et l'enroulement 50 s'étendent de manière sensiblement perpendiculaire à l'axe de symétrie 15. Les portions proximale 13 et distale 17 sont représentées sous la forme d'une barre de section sensiblement cylindrique, comme les spires 10, mais pourrait prendre une autre forme, par exemple, elles pourraient prendre la forme d'un barreau de section rectangulaire, tel une lame.In an embodiment illustrated in figure 1 the elastic element comprises a torsion spring 5 formed of a spring helicoidal involute, hereinafter called "helical spring" comprising a winding 50 of one or more turns 10. A proximal portion 13 extends from the winding 50 and is fixed on the crimping support 3. A portion distal 17 extends from the winding 50 and is intended to cooperate with the article 6. In the state of rest, that is to say in the absence of vibration, the torsion spring 5 has a configuration in which the proximal and distal portions 17 extend substantially parallel to the axis of symmetry 15 (the portion 13 and the axis 15 are even substantially merged) and the winding 50 extend substantially perpendicular to the axis of symmetry 15. The proximal 13 and distal 17 portions are represented in the form of a bar of substantially cylindrical section, as the turns 10, but could take another form, for example, they could take the form of a bar of rectangular section, like a blade.

La longueur de la portion proximale 13 est déterminée, entre autres, par une amplitude de vibration souhaitée du support de sertissage 3 et un encombrement faible du système de sertissage 1. L'amplitude de vibration dépend, entre autre, de la longueur cumulé des spires 10 et de la portion proximale 13. La portion proximale 13 favorise une augmentation de l'amplitude par un effet de balancement. Les spires 10 facilitent plus ou moins les mouvements radiaux selon les axes 15 et 16 (respectivement indiqués par les flèches 110 et 120 dans la figure 2). La longueur de la portion distale 17 a moins d'importance sur le mode de vibration et peut être minimisée de manière à réduire l'encombrement du système de sertissage 1.The length of the proximal portion 13 is determined, inter alia, by a desired vibration amplitude of the crimping support 3 and a small size of the crimping system 1. The vibration amplitude depends, among other things, on the cumulative length of the turns 10 and the proximal portion 13. The proximal portion 13 promotes an increase in amplitude by a swaying effect. The turns 10 facilitate more or less the radial movements along the axes 15 and 16 (respectively indicated by the arrows 110 and 120 in the figure 2 ). The length of the distal portion 17 has less importance on the vibration mode and can be minimized so as to reduce the size of the crimping system 1.

En mode de vibration, les portions proximale 13 et distale 17 vont s'écarter de leur position de repos principalement dans le sens de l'enroulement des spires 10, tel que suggéré par les flèches dans la figure 2. Un mouvement des portions proximales 13 et distale 17 s'écartant dans une direction perpendiculaire au sens de l'enroulement des spires 10 n'est cependant pas exclu (comme indiqué par la flèche 100 dans la figure 1). Le ressort de torsion 5 est donc configuré de manière à permettre au support de sertissage 3 d'osciller dans les directions x, y et z (voir la figure 1), selon un mouvement rotatif par rapport à l'axe de symétrie 15 et 16 (indiqués par les flèches 110 et 120 dans la figure 2). Notons que les modes vibratoires selon les différents axes x, y et Z ne seront pas les mêmes. L'oeil percevra notamment plus facilement un mouvement selon une direction que selon une autre. Etant donné la configuration du ressort de torsion 5 et de l'arrangement des portions proximale 13 et distale 17, un mouvement purement en translation dans la direction z, c'est-à-dire sensiblement parallèle à l'axe de symétrie 15, est peu probable. La figure 3 montre le système de sertissage 1 vu du dessus (côté pierre 2) et l'oscillation selon le mouvement radial 151 qui décrit une ellipse. Ce mouvement favorise un effet de scintillement de la pierre 2.In vibration mode, the proximal portion 13 and distal portion 17 will deviate from their rest position mainly in the direction of the winding of the turns 10, as suggested by the arrows in FIG. figure 2 . A movement of the proximal portions 13 and distal 17 deviating in a direction perpendicular to the winding direction of the turns 10 is however not excluded (as indicated by the arrow 100 in the figure 1 ). The torsion spring 5 is thus configured to allow the crimping support 3 to oscillate in the x, y and z directions (see FIG. figure 1 ), according to a rotational movement relative to the axis of symmetry 15 and 16 (indicated by the arrows 110 and 120 in the figure 2 ). Note that vibratory modes according to the different axes x, y and Z will not be the same. The eye will perceive more easily a movement in one direction than in another. Given the configuration of the torsion spring 5 and the arrangement of the proximal portion 13 and distal portion 17, a movement purely in translation in the z direction, that is to say substantially parallel to the axis of symmetry 15, is unlikely. The figure 3 shows the crimping system 1 seen from above (stone side 2) and the oscillation according to the radial movement 151 which describes an ellipse. This movement promotes a flickering effect of the stone 2.

Quoique dans les figures 1 et 3, l'enroulement 50 du ressort de torsion 5 est représenté avec une section cylindrique, d'autres types de sections, comme une section conique, sont également possibles. De manière similaire, les spires 10 du ressort hélicoïdal 5 peuvent être jointives mais peuvent également être non-jointives.Although in Figures 1 and 3 , the winding 50 of the torsion spring 5 is shown with a cylindrical section, other types of sections, such as a conical section, are also possible. Similarly, the turns 10 of the coil spring 5 may be contiguous but may also be non-contiguous.

Selon une autre forme d'exécution illustrée à la figure 4, le ressort de torsion 5 comprend une lame de ressort torsadée 51. Dans la figure 4, les portions proximale 13 et distale 17 sont formées avec la même lame formant la lame torsadée 51. La lame ressort formant la portion proximale 13 est orientée sensiblement à 90° par rapport à la lame ressort formant la portion distale 17, le ressort de torsion 5 étant formé par la portion torsadée 51 de la lame.According to another embodiment illustrated in figure 4 the torsion spring 5 comprises a twisted spring blade 51. In the figure 4 , the proximal portion 13 and distal portion 17 are formed with the same blade forming the twisted blade 51. The spring blade forming the proximal portion 13 is oriented substantially at 90 ° with respect to the spring blade forming the distal portion 17, the torsion spring 5 being formed by the twisted portion 51 of the blade.

Le ressort torsadé 51 peut comprendre une torsion ou pliage de la lame ressort selon un angle de torsion plus ou moins grand que 90°, ou encore plusieurs torsions de la lame. Les portions proximale 13 et distale 17 ne sont pas nécessairement formées intégralement avec le ressort torsadé 51 mais peuvent être fabriqués indépendamment et fixées au ressort torsadé 51 par la suite.The twisted spring 51 may comprise a torsion or folding of the spring blade at a torsion angle greater or less than 90 °, or several twists of the blade. The proximal 13 and distal 17 portions are not necessarily integrally formed with the twisted spring 51 but may be independently manufactured and attached to the twisted spring 51 thereafter.

Dans tous les cas, l'élément élastique 5 a préférablement une raideur comprise entre 1.2x10-5 N/m et 1.4x10+1 N/m et la masse combinée du support de sertissage 3 et de la pierre précieuse 2 est préférablement comprise entre 3x10-4 g et 4x10-1 g. Le support de sertissage 3 peut ainsi osciller selon un mouvement axial et/ou radial par rapport à un axe de symétrie 15, suite à un mouvement de l'article 6, avec une fréquence d'oscillation comprise entre 1 Hz et 30 Hz. Selon une forme d'exécution privilégiée, la masse combinée M du support de sertissage 3 et de la pierre précieuse 2 est comprise entre 1x10-3 g et 1x10-1 g, et la raideur K de l'élément élastique 5 est comprise entre 3.9x10-5 N/m et 3.6 N/m. D'une manière encore plus privilégiée la masse combinée M du support de sertissage 3 et de la pierre précieuse 2 est comprise entre 1x10-2 g et 5x10-2 g, et la raideur K de l'élément élastique 5 est comprise entre 3.9x10-4 N/m et 1.8 N/m. Selon une autre forme d'exécution privilégiée, dans laquelle le support de sertissage 3 peut osciller selon un mouvement axial et/ou radial, suite à un mouvement de l'article 6, avec une fréquence d'oscillation comprise entre 10 Hz et 20 Hz par rapport à l'axe de symétrie 15, la masse combinée M du support de sertissage 3 et de la pierre précieuse 2 est comprise entre 1x10-2 g et 5x10-2 g, et la raideur K de l'élément élastique 5 est comprise entre 3.9x10-2 N/m et 7.9x10-1 N/m.In all cases, the elastic element 5 preferably has a stiffness between 1.2x10 -5 N / m and 1.4x10 +1 N / m and the combined mass of the crimping support 3 and the gemstone 2 is preferably between 3x10-4 g and 4x10-1 g. The crimping support 3 can thus oscillate in axial and / or radial movement with respect to an axis of symmetry 15, following a movement of the article 6, with an oscillation frequency of between 1 Hz and 30 Hz. a preferred embodiment, the combined mass M of the crimping support 3 and the gemstone 2 is between 1x10 -3 g and 1x10 -1 g, and the stiffness K of the elastic element 5 is between 3.9x10 -5 N / m and 3.6 N / m. In a still more preferred manner the combined mass M of the crimping support 3 and the gemstone 2 is between 1x10 -2 g and 5x10 -2 g, and the stiffness K of the elastic element 5 is between 3.9x10 -4 N / m and 1.8 N / m. According to another preferred embodiment, in which the crimping support 3 can oscillate according to an axial and / or radial movement, following a movement of the article 6, with an oscillation frequency of between 10 Hz and 20 Hz relative to the axis of symmetry 15, the combined mass M of the crimping support 3 and the gemstone 2 is between 1x10 -2 g and 5x10 -2 g, and the stiffness K of the elastic element 5 is included between 3.9x10 -2 N / m and 7.9x10 -1 N / m.

L'amplitude du mouvement radial peut être limitée par une combinaison de la raideur K de l'élément élastique 5 et la masse combinée du support de sertissage 3 et de la pierre précieuse 2.The amplitude of the radial movement can be limited by a combination of the stiffness K of the elastic element 5 and the combined mass of the crimping support 3 and the gemstone 2.

Selon un mode de réalisation montré à la figure 5, la portion distale 17 est fixée à l'article 6 par l'intermédiaire d'un élément de fixation distal 14. Dans l'exemple illustré, l'élément de fixation distal comprend une tige 14 s'étendant essentiellement perpendiculairement à l'axe de symétrie 15. La tige 14 peut recevoir une pluralité de systèmes de sertissage 1, ces derniers pouvant être plus ou moins rapprochés les uns des autres, de manière à obtenir un assemblage de système de sertissage 1 produisant un effet visuel donné lorsque les systèmes de sertissage 1 sont en vibration. Une matrice de systèmes de sertissage 1 peut être obtenue en assemblant plusieurs tiges 14, chacune comprenant une pluralité de systèmes de sertissage 1.According to an embodiment shown in figure 5 the distal portion 17 is attached to the article 6 via a distal fixation member 14. In the illustrated example, the distal fixation member comprises a rod 14 extending substantially perpendicular to the axis The rod 14 can receive a plurality of crimping systems 1, the latter being more or less close to each other, so as to obtain a crimping system assembly 1 producing a given visual effect when the crimping systems 1 crimping 1 are in vibration.
