Description

Domaine techniqueTechnical area

La présente invention concerne un dispositif de fixation d'un système de sertissage permettant de fixer un support de sertissage de manière flexible sur un article d'horlogerie ou de joaillerie. L'invention concerne également un système de sertissage comprenant un tel dispositif de fixation.The present invention relates to a device for fixing a crimping system for fixing a crimping support flexibly on a timepiece or jewelery. The invention also relates to a crimping system comprising such a fixing device.

Etat de la techniqueState of the art

Les systèmes de sertissage permettent 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 make it possible 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.

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.

Un autre problème associé aux systèmes de sertissage connus est qu'ils sont susceptibles à une séparation accidentelle du chaton et/ou une déformation du ressort suite à un choc important.Another problem associated with known crimping systems is that they are susceptible to accidental separation of the kitten and / or deformation of the spring following a major shock.

Dans le cas de ressorts de petites dimensions, la faible épaisseur des parois (ou spires) du ressort ne permet pas de chasser le ressort dans un alésage, les déformations étant trop importante pour une bonne tenue du ressort. La fixation du ressort par collage n'est pas non plus avantageuse puisqu'il est difficile de maitriser la quantité de colle. A moins de laisser suffisamment de place entre la zone de collage et les spires du ressort, les spires risquent d'être baignées dans la colle due à l'effet de capillarité ou par écoulement de la colle.In the case of springs of small dimensions, the small thickness of the walls (or turns) of the spring does not allow to drive the spring in a bore, the deformations being too important for a good holding of the spring. Fixing the spring by gluing is also not advantageous since it is difficult to control the amount of glue. Unless enough space is left between the bonding zone and the spring turns, the turns may be bathed in the adhesive due to the effect of capillarity or flow of the adhesive.

Un but de la présente invention est de proposer un dispositif de fixation d'un système de sertissage pour un article d'horlogerie ou de joaillerie exempt des limitations des systèmes connus.An object of the present invention is to provide a device for fixing a crimping system for a timepiece or jewelery free from the limitations of known systems.

Un autre but de l'invention est d'obtenir un dispositif de fixation d'un système de sertissage qui comprenne un ressort hélicoïdal pouvant être fixé sans qu'il y ait de déformation rémanente des extrémités du ressort et qui permette d'assurer la tenue du ressort lorsque le système de sertissage vibre.Another object of the invention is to obtain a device for fixing a crimping system which comprises a helical spring which can be fixed without there being any residual deformation of the ends of the spring and which makes it possible to hold spring when the crimping system vibrates.

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

La figure 1 montre une vue en coupe d'un système de sertissage 1 est illustré à la figure 1. 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. Le support de sertissage 3 peut comprendre une partie de forme tronconique et servant de siège à la culasse 8 de la pierre 2. Le système de sertissage 1 comprend également un élément élastique 5, représenté dans la figure 1 par un ressort hélicoïdal de section cylindrique, dont une extrémité proximale 13 est fixée au support de sertissage 3 par l'intermédiaire d'un élément de fixation proximal 30. Une extrémité distale 17 du ressort 5 est fixée à article d'horlogerie ou de joaillerie 6 par l'intermédiaire d'un élément de fixation distal 14. Dans la figure 1, le système de sertissage 1 comprend une butée 18 plus rigide que l'élément élastique 5 et arrangée pour coopérer avec le support de sertissage 3 de manière à limiter l'amplitude du mouvement axial et/ou radial de la pierre 2 lorsque cette dernière oscille.The figure 1 shows a sectional view of a crimping system 1 is shown in the figure 1 . The crimping system 1 comprises a support of crimping 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. The crimping support 3 may comprise a portion of frustoconical shape and serving as a seat for the yoke 8 of the stone 2. The crimping system 1 also comprises an elastic element 5, represented in FIG. figure 1 by a helical spring of cylindrical section, a proximal end 13 of which is fixed to the crimping support 3 by means of a proximal fastening element 30. A distal end 17 of the spring 5 is attached to a timepiece or a piece of jewelery 6 via a distal fixation element 14. In the figure 1 , the crimping system 1 comprises a stop 18 more rigid than the elastic element 5 and arranged to cooperate with the crimping support 3 so as to limit the amplitude of the axial and / or radial movement of the stone 2 when the latter oscillates .

Dans cet arrangement, l'élément élastique 5 relie élastiquement le support de sertissage 3 avec la pierre 2 à l'article 6, de sorte que la pierre 2 puisse 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 distale 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.In this arrangement, the elastic element 5 elastically connects the crimping support 3 with the stone 2 to the article 6, so that the stone 2 can oscillate or vibrate on the elastic element 5 following a movement of the article 6 (in other words, 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 jewelry item 6 comprising the crimping system 1, the distal end 17 of the elastic element 5 fixed on the article 6 remains fixed, while the rest of the elastic element 5 is deformed 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.

Dans un tel arrangement, 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. Le système de sertissage 1 est destiné à créer une animation sur un article d'horlogerie 6 ou de joaillerie, 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 rapide mais bien 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.In such an arrangement, the oscillation of the stone 2 is in a radial movement with respect to an axis of symmetry 15 and a axial movement with respect to this same axis 15. The crimping system 1 is intended to create an animation on a timepiece 6 or jewelery, for example on a watch face, on the basis of a vibration of the stone . In other words, the crimping system 1 must be configured so that the vibration of the stone is fast but clearly 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 typiquement 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 typically between 1 Hz and 30 Hz.

Dans la forme d'exécution particulière de la figure 1, l'élément élastique comprend un ressort 5 à développement en hélicoïde (par la suite "ressort hélicoïdal") de section cylindrique. Le ressort 5 comprenant des spires 10 enroulées en hélice permet d'obtenir un élément élastique ayant, à la fois, une longueur maximale et un encombrement minimal. La figure 2 montre une vue de côté du ressort 5 et la figure 3 montre un détail d'une des extrémités 13, 17 du ressort 5. L'élément de fixation distal comprend une goupille 14. L'élément de fixation proximal est une cheville 30, solidaire avec le support de sertissage 3 et venant se loger, au moins en partie, dans l'extrémité proximale 13 du ressort 5, de manière à fixer la cheville 30 à l'élément élastique 5 par serrage.In the particular embodiment of the figure 1 , the elastic element comprises a coil-shaped spring 5 (hereinafter "coil spring") of cylindrical section. The spring 5 comprising helically wound turns 10 makes it possible to obtain an elastic element having both a maximum length and a minimum space requirement. The figure 2 shows a side view of spring 5 and the figure 3 shows a detail of one of the ends 13, 17 of the spring 5. The distal fixing member comprises a pin 14. The proximal fastening element is an ankle 30, integral with the crimping support 3 and being housed, at less in part, in the proximal end 13 of the spring 5, so as to fix the pin 30 to the elastic member 5 by clamping.

Dans un mode de réalisation, un système de fixation du système de sertissage 1 comprend un élément de fixation distal 14 arrangé pour recevoir, par chassage, l'extrémité distale 17 du ressort 5 de manière à fixer le ressort 5 à l'article 6. Le système de fixation comprend également une rainure axiale distale 52 pratiquée dans l'extrémité distale 17 du ressort 5 et s'étendant axialement. La rainure axiale distale 52 permet d'absorber radialement au moins une partie de l'effort de chassage de l'extrémité distale 17 sur l'élément de fixation distal 14.In one embodiment, an attachment system of the crimping system 1 comprises a distal fastener 14 arranged to receive, by driving, the distal end 17 of the spring 5 so as to secure the spring 5 to the article 6. The fixation system also includes a distal axial groove 52 formed in the distal end 17 of the spring 5 and extending axially. The distal axial groove 52 makes it possible to absorb radially at least a portion of the driving force of the distal end 17 on the distal fixation element 14.

Le système de fixation comprend également une rainure radiale distale 51 pratiquée dans l'extrémité distale 17 du ressort 5 et s'étendant de manière périphérique. Un ergot distal 141 solidaire de l'élément de fixation distal 14 est configuré pour permettre le chassage de l'extrémité distale 17 sur l'élément de fixation distal 14. L'ergot distal 141 est également configuré pour coopérer avec la première rainure radiale distale 51 quand l'extrémité distale 17 est chassée sur l'élément de fixation distal 14 de sorte à verrouiller axialement le ressort 5.The fixation system also includes a distal radial groove 51 formed in the distal end 17 of the spring 5 and extending peripherally. A distal lug 141 integral with the distal fixation element 14 is configured to allow the distal end 17 to be driven on the distal fixation element 14. The distal lug 141 is also configured to cooperate with the first distal radial groove 51 when the distal end 17 is driven on the distal fixing element 14 so as to axially lock the spring 5.

Selon une forme d'exécution illustrée aux figures 1 et 4, l'élément de fixation distal comprend une goupille 14 s'étendant à l'intérieur du ressort 5. La figure 4 montre un détail de l'extrémité distale 17 du ressort 5 chassée sur la goupille 14.According to an embodiment illustrated at figures 1 and 4 , the distal fixation member comprises a pin 14 extending inside the spring 5. The figure 4 shows a detail of the distal end 17 of the spring 5 driven on the pin 14.

Dans un mode de réalisation, le système de fixation comprend également un élément de fixation proximal 30 arrangé pour recevoir, par chassage, l'extrémité proximale 13 du ressort 5 de manière à fixer le ressort 5 au support de sertissage 3. L'élément de fixation proximal comprend une seconde rainure axiale proximale 52' pratiquée dans l'extrémité proximale 13 du ressort 5 et s'étendant axialement. La rainure axiale proximale 52' permet d'absorber radialement au moins une partie de l'effort de chassage de l'extrémité proximale 13 sur l'élément de fixation proximal 30. Le système de fixation comprend également une rainure radiale proximale 51' pratiquée dans l'extrémité proximale 13 du ressort 5 et s'étendant de manière périphérique. Un ergot proximal 141', solidaire de l'élément de fixation proximal 30, est configuré pour permettre le chassage de l'extrémité proximale 13 sur l'élément de fixation proximal 30 et pour coopérer avec la rainure radiale proximale 51', quand l'extrémité proximale 13 est chassée sur l'élément de fixation proximal 30 de sorte à verrouiller axialement le ressort 5.In one embodiment, the fixation system also includes a proximal fixation member 30 arranged to receive, by driving, the proximal end 13 of the spring 5 so as to secure the spring 5 to the crimping support 3. The proximal fixation includes a second proximal axial groove 52 'formed in the proximal end 13 of the spring 5 and extending axially. The proximal axial groove 52 'makes it possible to radially absorb at least part of the driving force from the proximal end 13 to the proximal fixation element 30. The fixation system also comprises a proximal radial groove 51' made in the proximal end 13 of the spring 5 and extending peripherally. A proximal lug 141 ', integral with the proximal fixation element 30, is configured to allow the proximal end 13 to be driven onto the proximal fixation element 30 and to cooperate with the proximal radial groove 51', when the proximal end 13 is driven onto the proximal fixation element 30 so as to axially lock the spring 5.

La rainure radiale distale 51 et/ou la rainure radiale proximale 51' peut être pratiquée dans une première (ou dernière) spire 11 du ressort 5 (voir la figure 3). Autrement dit, l'extrémité distale 17 correspond à une première spire 11 et l'extrémité proximale 13 correspond à une dernière spire 11' du ressort 5.The distal radial groove 51 and / or the proximal radial groove 51 'may be made in a first (or last) turn 11 of the spring 5 (see FIG. figure 3 ). In other words, the distal end 17 corresponds to a first turn 11 and the proximal end 13 corresponds to a last turn 11 'of the spring 5.

Les rainures radiales distale 51 et proximale 51' permettent de chasser le ressort 5 sur la goupille 14 et la cheville 30, respectivement, sans qu'il y ait de déformation rémanente des extrémités distale 17 et proximale 13 du ressort 5. Les rainures radiales distale 51 et proximale 51' assurent donc un maintien du ressort 5 sur la goupille 14 et la cheville 30 et un bon alignement du ressort 5 par rapport à l'article 6 et au support de sertissage 3.The radial distal 51 and proximal 51 'grooves allow to drive the spring 5 on the pin 14 and the ankle 30, respectively, without there being any residual deformation of the distal 17 and proximal 13 ends of the spring 5. The distal radial grooves 51 and proximal 51 'thus ensure a maintenance of the spring 5 on the pin 14 and the pin 30 and a good alignment of the spring 5 relative to the article 6 and the crimping support 3.

L'ergot distal 141 et/ou proximal 141' permettent de bloquer le ressort 5 sur la goupille 14 et/ou la cheville 30, de sorte que le ressort 5 ne puisse pas glisser sur la goupille 14 et/ou la cheville 30 lorsque le système de sertissage 1 vibre.The distal lug 141 and / or proximal 141 'can lock the spring 5 on the pin 14 and / or the pin 30, so that the spring 5 can not slide on the pin 14 and / or the pin 30 when the crimping system 1 vibrates.

Dans un mode de réalisation, le ressort cylindrique a une hauteur (distance entre l'extrémité proximale 13 et l'extrémité distale 17) d'environ 2 à 3 mm, un diamètre d'environ 2 mm et l'épaisseur des spires 10 est comprise entre environ 20 µm et 80 µm. De façon préférée, la hauteur est d'environ 1.6 mm. La première spire 11 et la dernière spire 11' ont chacune une hauteur d'environ un dixième de la hauteur du ressort 5. La hauteur de la première et dernière spire 11, 11' peut être déterminée de manière à être apte au guidage des extrémités du ressort 5 (hauteur minimale pour assurer que le ressort 5 soit droit). De manière avantageuse, la première spire 11 et la dernière spire 11' ont chacune une hauteur d'environ 0.2 mm.In one embodiment, the cylindrical spring has a height (distance between the proximal end 13 and the distal end 17) of about 2 to 3 mm, a diameter of about 2 mm and the thickness of the turns 10 is between about 20 μm and 80 μm. Preferably, the height is about 1.6 mm. The first turn 11 and the last turn 11 'each have a height of about one tenth of the height of the spring 5. The height of the first and last turn 11, 11' can be determined so as to be able to guide the ends spring 5 (minimum height to ensure that spring 5 is straight). Advantageously, the first turn 11 and the last turn 11 'each have a height of about 0.2 mm.
