Description
MOUVEMENT D'HORLOGERIE WATCHMAKING MOVEMENT
La présente invention se rapporte au domaine de l'horlogerie. Elle concerne notamment un mouvement d'horlogerie, pour une montre-bracelet mécanique ou une pièce d'horlogerie mécanique, comprenant une pluralité de tourbillons. On connaît, par exemple par le document CH698622, des mouvements d'horlogerie avec deux voire plus d'organes réglant, par exemple deux tourbillons, entraînés par un engrenage différentiel. Dans ces mouvements, l'engrenage différentiel comporte un organe d'entrée, alimenté par l'énergie provenant d'un barillet ou une autre source d'énergie équivalente, et deux organes de sorties entraînant chacun un organe réglant par l'intermédiaire d'un rouage multiplicateur approprié. The present invention relates to the field of watchmaking. It relates in particular to a watch movement, for a mechanical wristwatch or a mechanical timepiece, comprising a plurality of vortices. For example, document CH698622 discloses watch movements with two or more regulating members, for example two vortices, driven by a differential gear. In these movements, the differential gear comprises an input member, powered by energy from a barrel or other equivalent energy source, and two output members each driving a regulating member through a suitable gearbox.
Cette solution technique, comporte toutefois des inconvénients liés au couplage des deux oscillateurs alimentés par une même source d'énergie. Notamment, lors de deux impulsions simultanées sur les deux organes réglant, on a observé que l'engrenage différentiel fournit d'abord l'énergie à la chaîne cinématique qui en nécessite le moins, et seulement après à l'autre. Cela a pour conséquence une impulsion moins efficace et une perte de l'amplitude des oscillations du balancier, ce qui est néfaste à la précision de la marche. This technical solution, however, has disadvantages related to the coupling of the two oscillators powered by the same energy source. In particular, during two simultaneous pulses on the two regulating members, it has been observed that the differential gear first supplies energy to the kinematic chain which requires the least, and only after the other. This results in a less efficient pulse and a loss of the amplitude of the oscillations of the balance, which is detrimental to the accuracy of walking.

ensembles de régulation. Chaque ensemble de régulation est entraîné par un organe élastique prévu jusqu'au mobile d'échappement.

The object of the present invention is to provide a watch movement comprising a double tourbillon to increase the accuracy of the watch while optimizing the occupied space.
Conformément à l'invention, un mouvement d'horlogerie comprend au moins deux mécanismes de tourbillon, un premier mécanisme de tourbillon comprenant une première cage mobile en rotation autour d'un premier axe et sur laquelle sont montés pivotant un premier balancier et un premier mobile d'échappement, un second mécanisme de tourbillon comprenant une deuxième cage mobile en rotation autour d'un second axe parallèle audit premier axe, et sur laquelle sont montés pivotant un

Dans une autre forme d'exécution, la troisième cage est mobile en rotation autour d'un troisième axe qui intercepte les premier et deuxième axes. Toujours selon cette autre forme d'exécution, la quatrième cage est mobile en rotation autour d'un quatrième axe qui est normal au troisième axe.

- La figure 3 représente une vue éclaté d'un double tourbillon selon la présente invention. - Figure 3 shows an exploded view of a double vortex according to the present invention.
Comme illustré à la figure 1 , un mouvement d'horlogerie comprend deux mécanismes de tourbillon 4, 5. Un premier mécanisme de tourbillon 4 comprend une première cage C1 mobile en rotation autour d'un premier axe A1 et sur laquelle sont montés pivotant un premier balancier 6 et un premier mobile d'échappement 7. Un second mécanisme de tourbillon 5 comprend une deuxième cage C2 mobile en rotation autour d'un second axe A2, parallèle audit premier axe A1 , et sur laquelle sont montés pivotant un deuxième balancier 60 et un deuxième mobile d'échappement 70. Le mouvement comporte en outre une troisième cage C3 mobile en rotation autour d'un troisième axe A3 qui intercepte les premier et deuxième axes
A1 , A2. Les première et deuxième cages C1 , C2 sont superposées et sont portées par la troisième cage C3. Le mouvement comporte une quatrième cage C4 rotative autour d'un quatrième axe A4, normal au troisième axe A3, ladite quatrième cage C4 portant la troisième cage C3 La et l'entraînant cinématiquement. Les première et deuxième cages C1 , C2 sont superposées et sont portées par la troisième cage C3. As illustrated in FIG. 1, a clockwork movement comprises two vortex mechanisms 4, 5. A first vortex mechanism 4 comprises a first cage C1 movable in rotation around a first axis A1 and on which are mounted pivoting a first balance wheel 6 and a first escapement mobile 7. A second vortex mechanism 5 comprises a second cage C2 rotatable about a second axis A2, parallel to said first axis A1, and on which are pivotally mounted a second balance 60 and a second movable exhaust 70. The movement further comprises a third cage C3 rotatable about a third axis A3 which intercepts the first and second axes A1, A2. The first and second cages C1, C2 are superimposed and are carried by the third cage C3. The movement comprises a fourth cage C4 rotatable about a fourth axis A4, normal to the third axis A3, said fourth cage C4 carrying the third cage C3 La and driving it kinematically. The first and second cages C1, C2 are superimposed and are carried by the third cage C3.
Dans cet exemple, les deux mécanismes de tourbillon 4, 5 sont coaxiaux. Chaque mécanisme de tourbillon 4, 5 peut tourner selon un axe indépendant ou un seul axe commun. In this example, the two vortex mechanisms 4, 5 are coaxial. Each vortex mechanism 4, 5 can rotate along an independent axis or a single common axis.
Toujours selon cet exemple illustré à la figure 1 , un anneau 9 denté est fixé sur un mouvement (non illustré). La quatrième cage C4 tourne concentrique à cet anneau denté 9 qui constitue la roue fixe de la quatrième cage C4. Still according to this example illustrated in Figure 1, a toothed ring 9 is fixed on a movement (not shown). The fourth cage C4 concentrically rotates to this toothed ring 9 which constitutes the fixed wheel of the fourth cage C4.
Un mécanisme différentiel 8 est agencé entre les deux premières cages C1 , C2 superposées. Le mécanisme différentiel 8 tourne autour d'un axe A5 parallèle au premier et second axe A1 , A2 et perpendiculaire au troisième axe A3. Comme illustré à la figure 2, les mécanismes de tourbillon 4, 5 sont agencés au centre d'une montre-bracelet. Dans cet exemple, l'affichage de l'heure est excentré par rapport aux mécanismes de tourbillon 4, 5. En effet, des index 12 sont représentés par des pierres serties de couleur différente par rapport au reste du cadran. De la même manière, l'indication des heures est donnée par un premier ensemble 13 de deux pierres serties, sur une première bague 15, de couleur différente par rapport au reste des pierres serties sur ladite première bague 1 5 et l'indication des minutes est donnée par un second ensemble 14 de trois pierres serties, sur une seconde bague 16, de couleur différente par rapport au reste des pierres serties sur ladite seconde bague 16. Les première et seconde bagues 1 5, 16 se déplacent donc indépendamment l'une de l'autre. Dans une variante non illustrée, les première et seconde bagues 15, 1 6 serties peuvent être remplacées par deux bagues 15, 16 comportant chacune une indication, par exemple un marquage ou une gravure, de manière à obtenir un affichage le plus simple possible, La quatrième cage C4 est agencée pour effectuer un tour sur elle-même en une minute. La troisième cage C3 est agencée pour effectuer un tour sur elle-même en une minute également, tout comme la première cage 1 qui porte le premier tourbillon 4 et la deuxième cage C2 qui porte le deuxième tourbillon 5. La montre-bracelet comporte
un cadran de forme concave selon au moins un rayon de courbure, qui entoure les mécanismes de tourbillons 4, 5. Dans cet exemple, le cadran reçoit des pierres précieuses ou semi-précieuses de manière à réaliser un pavage pour offrir un effet esthétique fort, notamment par le reflet des pierres précieuses ou semi-précieuses sur le cadran. La troisième cage 3 est à fleur avec l'ouverture centrale du cadran. A differential mechanism 8 is arranged between the two first superposed cages C1, C2. The differential mechanism 8 rotates about an axis A5 parallel to the first and second axis A1, A2 and perpendicular to the third axis A3. As illustrated in Figure 2, the tourbillon mechanisms 4, 5 are arranged in the center of a wristwatch. In this example, the time display is eccentric with respect to vortex mechanisms 4, 5. Indeed, indexes 12 are represented by stones set with a different color compared to the rest of the dial. In the same way, the indication of the hours is given by a first set 13 of two set stones, on a first ring 15, of different color compared to the rest of the stones crimped on said first ring 1 5 and the indication of the minutes is given by a second set 14 of three set stones, on a second ring 16, of different color compared to the rest of the stones crimped on said second ring 16. The first and second rings 1 5, 16 therefore move independently one the other. In a variant not illustrated, the first and second crimped rings 15, 1 6 may be replaced by two rings 15, 16 each having an indication, for example a marking or an engraving, so as to obtain the simplest possible display, fourth cage C4 is arranged to perform a turn on itself in one minute. The third cage C3 is arranged to perform a turn on itself in one minute as well, as the first cage 1 which carries the first vortex 4 and the second cage C2 which carries the second vortex 5. The wristwatch comprises a dial of concave shape according to at least one radius of curvature, which surrounds the vortex mechanisms 4, 5. In this example, the dial receives gems or semi-precious stones so as to effect a tiling to offer a strong aesthetic effect, especially by the reflection of precious or semi-precious stones on the dial. The third cage 3 is flush with the central opening of the dial.
Comme illustré à la figure 3 dans une vue éclatée, le premier mécanisme de tourbillon 4 comprend une première cage C1 mobile en rotation autour d'un premier axe A1 et sur laquelle sont montés pivotant un premier balancier 6 et un premier mobile d'échappement 7, un second mécanisme de tourbillon 5 comprenant une deuxième cage C2 mobile en rotation autour d'un second axe A2 et sur laquelle sont montés pivotant un deuxième balancier 60 et un deuxième mobile d'échappement 70. Le mouvement comporte en outre une troisième cage C3 mobile en rotation autour d'un troisième axe A3. La troisième cage C3 est agencée pour être portée et entraînée cinématiquement par une quatrième cage C4 (non illustrée) mobile en rotation autour d'un quatrième axe. As illustrated in FIG. 3 in an exploded view, the first vortex mechanism 4 comprises a first cage C1 movable in rotation about a first axis A1 and on which are pivotally mounted a first rocker 6 and a first mobile 7 , a second vortex mechanism 5 comprising a second cage C2 movable in rotation about a second axis A2 and on which are pivotally mounted a second rocker 60 and a second mobile exhaust 70. The movement further comprises a third cage C3 mobile in rotation about a third axis A3. The third cage C3 is arranged to be carried and driven kinematically by a fourth cage C4 (not shown) rotatable about a fourth axis.
Les deux premières cages C1 , C2, la troisième cage C3 et la quatrième cage C4 peuvent tourner à des vitesses différentes les unes par rapport aux autres, comme par exemple une quatrième cage C4 qui effectuerait un tour sur elle-même en deux minutes alors que les première et deuxième cages C1 , C2 et la troisième cage C3 effectueraient un tour sur elles-mêmes en une minute. The first two cages C1, C2, the third cage C3 and the fourth cage C4 can rotate at different speeds relative to each other, such as for example a fourth cage C4 which would perform a turn on itself in two minutes while the first and second cages C1, C2 and the third cage C3 would turn on themselves in one minute.
Comme illustré à la figure 1 , le mécanisme différentiel 8 est agencé entre les deux premières cages C1 , C2 pour notamment répartir la force d'un train de rouages d'une manière équitable entre les deux tourbillons 4, 5, et faire la moyenne de la marche de chacun des deux tourbillons 4, 5 afin d'augmenter la précision de la montre. Plus précisément, le mécanisme différentiel 8 est agencé entre un élément supérieur 10 et un élément inférieur 1 1 de la troisième cage C3. As illustrated in FIG. 1, the differential mechanism 8 is arranged between the two first stands C1, C2 in particular to distribute the force of a gear train in an equitable manner between the two vortices 4, 5, and to average the the operation of each of the two swirls 4, 5 to increase the accuracy of the watch. More precisely, the differential mechanism 8 is arranged between an upper element 10 and a lower element 11 of the third cage C3.
La construction selon l'invention permet également de réaliser un mécanisme de tourbillon présentant un encombrement réduit, du fait notamment de l'empilement des deux tourbillons 4, 5 et d'imbrication des première et deuxième cages C1 , C2 dans la troisième cage de tourbillon C3.
Il est bien évident que la présente invention n'est pas limitée à la réalisation décrite. Notamment la forme des cages peut varier, ainsi que l'emplacement des tourbillons dans la pièce d'horlogerie.
