Description

La présente invention a pour objet un mécanisme de tourbillon ainsi qu'une pièce d'horlogerie munie d'un tel mécanisme. Plus particulièrement l'invention concerne un mécanisme de tourbillon volant, c'est-à-dire dont la cage rotative est montée en porte-à-faux sur l'axe d'un mobile porteur entraíné par le rouage moteur d'un mouvement de montre. Un tel montage en porte-à-faux du tourbillon est particulièrement avantageux lorsque le mécanisme de tourbillon doit être monté dans le mouvement de façon à pouvoir être visible. Dans ce cas en effet la vision du mécanisme de tourbillon n'est pas occultée par un pont ou un palier.The subject of the present invention is a tourbillon mechanism and a timepiece provided with such a mechanism. More particularly the invention a flying tourbillon mechanism, that is to say, whose rotating cage is mounted cantilever on the axis of a mobile carrier driven by the gear train motor of a watch movement. Such a mounting cantilever tourbillon is particularly advantageous when the vortex mechanism is to be mounted in the movement so as to be visible. In this case indeed vision of the vortex mechanism is not obscured by a bridge or a landing.

L'article de Friz Hönig "Das Tourbillon: Faszination der Drehung - Laute Bewunderung und viele leise Fragen" paru dans le magazine "Uhren Juwelen Schmuck, en décembre 1992 décrit un tourbillon volant avec cage à trois ponts, le pont intermédiaire soutenant la roue d'échappement, le pont intermédiaire étant en sandwich entre les ponts inférieur et supérieur.The article by Friz Hönig "Das Tourbillon: Faszination der Drehung - Laute Bewunderung und viele leise Fragen "published in the magazine" Uhren Juwelen Schmuck, December 1992 describes a flying tourbillon with three-decker cage, the intermediate bridge supporting the wheel exhaust system, the intermediate bridge being sandwiched between the lower and superior.

Ainsi l'un des buts de l'invention est de réaliser un mécanisme de tourbillon pouvant être intégré dans un mouvement d'horlogerie de manière à être visible par l'usager de la montre.Thus, one of the aims of the invention is to provide a whirl mechanism can be integrated into a clockwork movement so as to be visible by the user of the watch.

Un autre but de l'invention est de réaliser un assemblage particulier des ponts formant la cage rotative du tourbillon de manière à réaliser et garantir une grande rigidité de la cage et donc de permettre et de garantir une grande précision du montage des éléments mobiles, balancier, ancre et roue d'échappement du mécanisme de tourbillon sur ladite cage.Another object of the invention is to provide a particular assembly of bridges forming the rotary cage of the vortex so as to realize and guarantee a high rigidity of the cage and therefore allow and guarantee a high accuracy mounting of the moving parts, rocker arm, anchor and escape wheel vortex mechanism on said cage.

De plus, dans les mécanismes de tourbillon flottants habituels, il est toujours difficile d'assurer un parallélisme parfait ainsi qu'un entraxe précis entre l'axe de rotation de la cage de tourbillon, l'axe du mobile d'échappement et l'axe de la roue de secondes fixe engrenant avec le pignon d'échappement.Moreover, in the usual floating tourbillon mechanisms, it is always difficult to ensure perfect parallelism and a precise distance between the axis of rotation of the tourbillon cage, the axis of the exhaust mobile and the axis the fixed seconds wheel meshing with the exhaust pinion.

Un autre but de la présente invention est de garantir le parallélisme parfait et l'entraxe précis entre l'axe de rotation de la cage de tourbillon, l'axe du mobile d'échappement et l'axe de la roue de secondes pour améliorer les conditions d'engrainement du pignon d'échappement avec ladite route de secondes.Another object of the present invention is to guarantee the perfect parallelism and the precise spacing between the axis of rotation of the tourbillon cage, the axis of the mobile exhaust and the axis of the seconds wheel to improve the conditions exhaust pinion with said second road.

La présente invention a pour objet un mécanisme de tourbillon permettant d'atteindre les buts énoncés ci-dessus et en outre d'obtenir une esthétique particulière du fait que vu en plan les trois ponts formant la cage du tourbillon sont exactement de mêmes formes et dimensions.The subject of the present invention is a tourbillon mechanism enabling to achieve the goals stated above and furthermore to obtain an aesthetic peculiar to the fact that seen in plan the three bridges forming the cage of the vortex are exactly the same shapes and sizes.

L'invention a encore pour objet une pièce d'horlogerie incorporant ledit mécanisme de tourbillon selon la revendication 1.The invention also relates to a timepiece incorporating said vortex mechanism according to claim 1.

    • La présente invention a pour objet un mécanisme de tourbillon pour une pièce d'horlogerie dont la cage est suspendue, ce type de tourbillon étant généralement dénommé tourbillon volant. De cette façon, la cage du tourbillon n'étant reliée au mouvement que par un seul côté l'autre côté peut être entièrement visible ce qui est intéressant pour une pièce d'horlogerie dans laquelle le tourbillon est visible, soit à travers le cadran, soit au travers du fond de la boíte. La visibilité du tourbillon n'est pas entravée par un pont ou autre élément de maintien de la cage du tourbillon.The subject of the present invention is a vortex mechanism for a timepiece whose cage is suspended, this type of tourbillon being usually referred to as flying whirlwind. In this way, the whirlpool cage being connected to the movement only by one side the other side can be fully visible what is interesting for a timepiece in which the tourbillon is visible, either through the dial or through the bottom of the box. The visibility of the tourbillon is not impeded by a bridge or other element of maintaining the vortex cage.

    La cage de ce tourbillon volant est réalisée par trois ponts, un pont supérieur 3, un pont intermédiaire 2 et un pont inférieur 1 présentant vus en plan exactement la même forme et les mêmes dimensions de sorte qu'une fois assemblés si l'on regarde la cage de dessus ou de dessous lesdits ponts sont parfaitement superposés les uns aux autres.The cage of this flying tourbillon is made by three bridges, a bridge upper 3, an intermediate bridge 2 and a lower bridge 1 having seen in plan exactly the same shape and the same dimensions so that once assembled if we look at the cage from above or below said bridges are perfectly superimposed on each other.

    Ces trois ponts 1,2,3 sont assemblés par deux piliers comportant chacun une douille filetée intérieurement 4 et deux vis 5,5'. Les surfaces extérieures des douilles 4 sont ajustées dans des alésages 6,7,8 que comportent chacun des ponts 1,2,3. La longueur des douilles 4 est inférieure à l'épaisseur des trois ponts superposés au voisinage immédiat de leurs alésages 6,7,8 de sorte qu'en position de service assemblée les douilles 4 sont invisibles. Les vis 5,5' sont vissées dans les extrémités des douilles 4 et leurs têtes prennent appui contre les ponts supérieur 3 et inférieur 1 respectivement serrant les trois ponts 1,2,3 les uns contres les autres. De cette façon, le positionnement des ponts les uns par rapport aux autres est extrêmement précis et leur assemblage est très rigide, leur parfait parallélisme est également assuré.These three bridges 1,2,3 are assembled by two pillars each comprising an internally threaded socket 4 and two screws 5,5 '. The outer surfaces of sockets 4 are fitted in bores 6,7,8 which each bridges 1,2,3. The length of the sockets 4 is less than the thickness of the three bridges superimposed in the immediate vicinity of their bores 6,7,8 so that in position of service assembled the sockets 4 are invisible. The screws 5,5 'are screwed into the ends of the sockets 4 and their heads bear against the bridges upper 3 and lower 1 respectively squeezing the three bridges 1,2,3 one against others. In this way, the positioning of the bridges relative to each other to others is extremely accurate and their assembly is very rigid, their perfect parallelism is also assured.

    Dans la forme d'exécution illustrée à la figure 1, la douille 4 de chaque pilier comporte une nervure 9 circulaire sur sa périphérie ce qui facilite le montage et l'assemblage des ponts 1,2,3. Dans cette exécution, on peut introduire le haut des douilles 4 dans les alésages 6,7 des ponts inférieur 1 et intermédiaire 2. Cette nervure 9 des douilles 4 vient buter contre le pont intermédiaire 2 et avec la vis 5 les ponts 1 et 2 peuvent être serrés ensemble et solidarisés des douilles 4. Ensuite, le pont supérieur 3 est enfilé sur les douilles 4 et vient buter contre la face inférieure du pont intermédiaire 2. Les vis 5' permettent de bloquer ce pont supérieur 3 contre le pont intermédiaire 2.In the embodiment illustrated in FIG. 1, the bushing 4 of each pillar has a circular rib 9 on its periphery which facilitates assembly and the assembly of bridges 1,2,3. In this execution, we can introduce the top of bushings 4 in the bores 6.7 of the lower 1 and intermediate 2 decks. rib 9 of the sockets 4 abuts against the intermediate bridge 2 and with the screw 5 bridges 1 and 2 can be clamped together and secured bushings 4. Then, the upper bridge 3 is threaded on the sockets 4 and abuts against the face lower the intermediate bridge 2. The screws 5 'can block this bridge upper 3 against the intermediate bridge 2.

    Les tolérances sur la surface cylindrique périphérique de la douille 4 et sur les alésages 6,7,8 des ponts 1,2,3 sont calculées et réalisées de manière à obtenir un positionnement sans jeu des trois ponts les uns sur les autres.Tolerances on the cylindrical peripheral surface of the sleeve 4 and on the bores 6,7,8 of the bridges 1,2,3 are calculated and realized so as to get a game-free positioning of the three bridges over each other.

    L'axe 10 du balancier 11 est pivoté entre le pont supérieur 3 et le pont inférieur 1 de la cage de tourbillon. Cet axe 10 porte le mobile 12 agissant sur l'ancre 13 qui elle est montée entre le pont intermédiaire 2 et le pont inférieur 1. Le mobile d'échappement formé par la roue d'échappement 14 et le pignon d'échappement 15 est également pivoté entre les ponts intermédiaire 2 et inférieur 1. La roue d'échappement 14 coopère avec l'ancre 13 tandis que le pignon d'échappement 15 est en prise avec la roue de secondes fixe 16.The axis 10 of the balance 11 is pivoted between the upper bridge 3 and the bridge bottom 1 of the tourbillon cage. This axis 10 carries the mobile 12 acting on the anchor 13 which is mounted between the intermediate bridge 2 and the lower bridge 1. The mobile exhaust formed by the escape wheel 14 and the pinion 15 is also pivoted between the intermediate bridges 2 and lower 1. The escape wheel 14 cooperates with the anchor 13 while the pinion exhaust 15 is engaged with the fixed seconds wheel 16.

    Un ressort spiral 30 est fixé par une de ses extrémités à l'axe 10 du balancier 11 et par son autre extrémité à l'aide d'un piton 31 et d'une vis 32 sur le pont supérieur 3 de la cage du tourbillon.A spiral spring 30 is fixed by one of its ends to the axis 10 of the beam 11 and its other end with a stud 31 and a screw 32 on the upper deck 3 of the tourbillon cage.

    Cette roue fixe de secondes 16 est fixée, ici par des vis 17, sur la platine 18 d'un mouvement d'horlogerie, platine 18 qui est solidaire du pont 19 du mouvement d'horlogerie.This fixed seconds wheel 16 is fixed, here by screws 17, on the plate 18 of a watch movement, platinum 18 which is secured to the bridge 19 of the clockwork movement.

    Le mouvement d'horlogerie comporte un mobile porteur de la cage de tourbillon dont l'axe 20 est pivoté entre le pont 19 et la platine 18 du mouvement d'horlogerie. Cet axe 20 porte la planche 21 du mobile porteur de cage qui est en prise avec un pignon 22 du rouage moteur du mouvement entraíné par un barillet ou un moteur.The watch movement comprises a mobile carrying the cage of vortex whose axis 20 is pivoted between the bridge 19 and the plate 18 of the movement watchmaking. This axis 20 carries the board 21 of the mobile cage carrier which is in taken with a pinion 22 of the drive train of the movement driven by a cylinder or an engine.

    L'extrémité inférieure de l'axe 20 du mobile porteur de cage du tourbillon comporte une extrémité filetée 23 et un bossage cylindrique 24 coaxial à l'axe 20.The lower end of the axis 20 of the mobile carrier cage tourbillon has a threaded end 23 and a cylindrical boss 24 coaxial with the axis 20.

    La cage inférieure 1 du tourbillon comporte un pied de fixation 25 comportant un alésage dont le diamètre correspond à celui du bossage 24 de l'axe 20 du mobile porteur. Le pied de fixation 25 de la cage inférieure du tourbillon est enfilé sur l'extrémité de l'axe 20 du mobile porteur et vient s'ajuster autour du bossage 24 garantissant un alignement exact de l'axe de rotation de la cage du tourbillon sur cet axe 20 du mobile porteur. Un écrou creux 26 est vissé sur l'extrémité filetée de l'axe 20 du mobile porteur et fixé à l'intérieur du pied de fixation 25. Cet écrou 26 comporte une tête venant prendre appui contre la face inférieure du pont inférieur 1 de la cage fixant celle-ci rigidement sur le mobile porteur 20,21.The lower cage 1 of the tourbillon has a fixing foot 25 having a bore whose diameter corresponds to that of the boss 24 of the axis 20 of the carrier. The attachment foot 25 of the lower vortex cage is threaded on the end of the axis 20 of the carrier and is adjusted around the boss 24 ensuring exact alignment of the axis of rotation of the cage of the vortex on this axis 20 of the carrier. A hollow nut 26 is screwed onto the threaded end of the axis 20 of the carrier and secured to the inside of the foot of 25. This nut 26 has a head bearing against the face bottom of the lower bridge 1 of the cage fixing it rigidly on the mobile carrier 20,21.

    La cage de tourbillon est ainsi solidaire du mobile porteur 20,21 dont l'axe est pivoté dans des paliers 27, 28 portés l'un par le pont 19 du mouvement et l'autre par la roue de secondes fixe 16 qui est elle-même fixée sur la platine 18 du mouvement. Grâce à ce montage on garantit une parfaite concentricité de la cage de tourbillon avec la roue de secondes fixe et donc avec le profil de la denture de cette roue de secondes fixe ce qui garantit un engrènement parfait entre le pignon d'échappement 15 et cette roue de secondes fixe 16.The tourbillon cage is thus secured to the carrier 20.21 whose axis is pivoted in bearings 27, 28 carried one by the bridge 19 of the movement and the other by the fixed seconds wheel 16 which is itself fixed on the plate 18 of the movement. Thanks to this assembly a perfect concentricity of the cage is ensured of whirlwind with fixed seconds wheel and so with the profile of the teeth of this seconds wheel sets which guarantees a perfect meshing between the pinion exhaust 15 and this fixed seconds wheel 16.

    Ainsi, le mécanisme de tourbillon décrit comporte un mobile porteur 20,21 de la cage de tourbillon pivoté entre deux paliers 27,28 dont l'un 28 est fixé dans la roue fixe de secondes 16, ce qui permet une parfaite coaxialité entre l'axe de rotation de la cage 1,2,3 du tourbillon et le profil de la denture de la roue fixe de secondes 16.Thus, the tourbillon mechanism described comprises a carrier 20.21 of the tourbillon cage pivoted between two bearings 27,28 of which one 28 is fixed in the fixed seconds wheel 16, which allows a perfect coaxiality between the axis of rotation of the cage 1,2,3 of the tourbillon and the profile of the toothing of the fixed wheel of seconds 16.

    Par ailleurs, la fixation particulière de la cage de tourbillon par son pied de fixation sur l'extrémité de l'axe du mobile porteur 20,21 comportant un filetage et un bossage 24 de centrage à l'aide d'un écrou creux 26 permet un alignement parfait entre l'axe du mobile porteur 20,21 et l'axe de la cage de tourbillon.Moreover, the particular attachment of the tourbillon cage by its foot of fixing on the end of the axis of the carrier 20,21 having a thread and a boss 24 of centering with a hollow nut 26 allows alignment perfect between the axis of the carrier 20,21 and the axis of the tourbillon cage.

    D'autre part, le montage en sandwich des ponts 1,2,3 en appui les uns contre les autres à l'aide de deux piliers permet un positionnement rigoureux des ponts les uns par rapport aux autres et un assemblage aisé et solide. De plus, les douilles 4 des piliers sont invisibles.On the other hand, the sandwich assembly of the bridges 1,2,3 in support of each against others using two pillars allows a rigorous positioning of bridges to each other and an easy and solid assembly. Moreover, the Sockets 4 of the pillars are invisible.

    Enfin, les trois ponts 1,2,3 ayant des formes identiques, l'esthétique de la cage du tourbillon volant est pure et sobre. Dans l'exemple décrit, les ponts 1,2,3, sont reliés par deux piliers 4 mais le nombre de ces piliers pourrait être supérieur suivant la forme des ponts.Finally, the three bridges 1,2,3 having identical shapes, the aesthetics of the flying tourbillon cage is pure and sober. In the example described, the bridges 1,2,3, are connected by two pillars 4 but the number of these pillars could be higher following the shape of the bridges.

    Dans l'exemple décrit la roue de secondes 16 est solidaire de la platine 18 du mouvement, elle est donc fixe, mais dans d'autres exécutions cette roue de secondes pourrait être mobile. Ce qui importe ici, c'est que l'un des paliers 27,28 du rouage porteur de la cage de tourbillon soit solidaire de cette roue de secondes 16.In the example described the seconds wheel 16 is secured to the plate 18 of movement, so it is fixed, but in other executions this wheel of seconds could be mobile. What matters here is that one of the 27,28 of the caster train of the tourbillon cage is integral with this wheel seconds 16.
