Description

La présente invention est relative à un mouvement de pièce d'horlogerie comprenant un carrousel formé d'une plate-forme portant une roue d'échappement et une ancre coopérant avec un balancier-spiral, un rouage de finissage en prise avec une roue à couronne portée par un barillet, et un mécanisme d'affichage de l'heure dérivé dudit rouage de finissage, ce mécanisme d'affichage étant associé à un mécanisme de mise à l'heure.The present invention relates to a timepiece movement comprising a carousel formed of a platform carrying an escape wheel and an anchor cooperating with a balance spring, a finishing gear engaged with a crown wheel carried by a cylinder, and a time display mechanism derived from said work train, this display mechanism being associated with a time setting mechanism.

Dans son acception convenue, un carrousel de pièce d'horlogerie est un système réglant composé généralement d'un assortiment conventionnel et d'un balancier comme le montre par exemple l'ouvrage « Théorie d'Horlogerie » de C.-A. Reymondin et al. (FET, CH-1347 Le Sentier, 1998, pages 167 et 168 ). Ces éléments sont placés sur une plate-forme servant de base et qui pivote entre un pont de plate-forme et une platine. Ici la plate.-forme fonctionne comme un mobile de seconde. Elle est solidaire d'un pignon de seconde et entraînée par une roue moyenne. Sur la plate-forme, le rôle de l'échappement est conventionnel. La force est transmise à partir d'un pignon d'échappement qui engrène, à la manière d'un satellite, avec une roue de seconde fixe solidaire de la platine. Dans cette réalisation bien connue, l'axe du balancier se trouve à une certaine distance de l'axe de la plate-forme et d'un premier côté de cet axe, alors que l'axe de la roue d'échappement se trouve à une certaine distance de l'axe de la plate-forme mais d'un second côté de cet axe, opposé au premier.In its agreed sense, a carousel of a timepiece is a regulating system generally composed of a conventional assortment and a pendulum as shown for example in the book "Theory of Watchmaking" of C.-A. Reymondin et al. (FET, CH-1347 The Path, 1998, pages 167 and 168 ). These elements are placed on a platform serving as a base and which pivots between a deck bridge and a deck. Here the platform works as a second mobile. It is secured to a second gear and driven by a medium wheel. On the platform, the role of the exhaust is conventional. The force is transmitted from an exhaust pinion which meshes, in the manner of a satellite, with a second fixed wheel secured to the plate. In this well-known embodiment, the axis of the balance is at a distance from the axis of the platform and a first side of this axis, while the axis of the escape wheel is at a certain distance from the axis of the platform but a second side of this axis, opposite the first.

Le document CH 7965 décrit un carrousel dans lequel l'axe du balancier est coaxial à l'axe de rotation de la platine tournante.The document CH 7965 describes a carousel in which the axis of the balance is coaxial with the axis of rotation of the turntable.

On peut considérer que le balancier et son pont tournent à la manière d'un cheval de bois sur la plate-forme d'un manège. On comprend donc le pourquoi de l'utilisation du terme de carrousel. Le carrousel, tout comme le tourbillon dont il est dérivé, fait prendre au balancier-spiral toutes les positions verticales. Ceci compense automatiquement les différences de marche, ce qui améliore le réglage.We can consider that the pendulum and its bridge turn in the manner of a wooden horse on the platform of a carousel. We understand so why use the term carousel. The carousel, just like the whirlpool from which it is derived, makes the balance-spring take all vertical positions. This automatically compensates for differences in operation, which improves the setting.

Le carrousel classique qui vient d'être décrit est monté généralement dans une pièce d'horlogerie comportant un rouage de finissage qui est en prise avec une roue de couronne portée par un barillet. Enfin ce mouvement connu comporte un mécanisme d'affichage de l'heure qui est dérivé du rouage de finissage, ce mécanisme d'affichage étant associé à un mécanisme de mise à l'heure.The conventional carousel that has just been described is generally mounted in a timepiece comprising a finishing gear which is engaged with a crown wheel carried by a barrel. Finally this known movement includes a time display mechanism which is derived from the work train, this display mechanism being associated with a time setting mechanism.

Le mouvement de la présente invention comporte également un carrousel avec l'avantage décrit plus haut de compenser automatiquement les différences de marche dues à la gravité qui s'exerce sur le balancier-spiral de la pièce d'horlogerie. En plus de cela ce mouvement entend faire jouer à la plate-forme du carrousel un rôle nouveau: celui d'indicateur de temps.The movement of the present invention also comprises a carousel with the advantage described above to automatically compensate for differences in travel due to the gravity that is exerted on the sprung balance of the timepiece. On top of that, this movement intends to make the carousel platform play a new role: that of time indicator.

Ainsi pour parvenir à ce but, la présente invention a pour objet un mouvement d'horlogerie conforme à la revendication 1 du brevet.Thus, to achieve this object, the present invention relates to a watch movement according to claim 1 of the patent.

L'invention va être expliquée maintenant en détail ci-dessous par un mode d'exécution donné en exemple non limitatif, cette exécution étant illustrée par les dessins annexés dans lesquels:

  • la figure 1 est une vue en perspective de la pièce d'horlogerie incluant le mouvement de l'invention,
  • la figure 2 est en vue en plan de l'ensemble du mécanisme contenu dans la pièce d'horlogerie représentée en figure 1,
  • la figure 3 est une coupe selon la ligne III-III montrée en figure 2,
  • la figure 4 est une vue en perspective du mécanisme montré en coupe sur la figure 3,
  • la figure 5 est une coupe selon la ligne V-V montrée en figure 2,
  • la figure 6 est une vue en perspective du mécanisme montré en coupe sur la figure 5, et
  • la figure 7 est une coupe de l'entraînement du plateau depuis les aiguilles.
The invention will now be explained in detail below by an embodiment given by way of non-limiting example, this embodiment being illustrated by the appended drawings in which:
  • the figure 1 is a perspective view of the timepiece including the movement of the invention,
  • the figure 2 is in plan view of the entire mechanism contained in the timepiece shown in FIG. figure 1 ,

  • the figure 5 is a section along the line VV shown in figure 2 ,
  • the figure 6 is a perspective view of the mechanism shown in section on the figure 5 , and
  • the figure 7 is a cut of the training tray from the needles.

Comme le montrent les figures le mouvement de la pièce d'horlogerie 1 comprend un carrousel 4. Ce carrousel est formé d'une plate-forme 5 portant une roue d'échappement 6 coopérant avec un balancier-spiral 7. Un rouage de finissage 31 est en prise avec une roue de couronne 17 portée par un barillet 18 comme on le voit bien sur la figure 3. Le mouvement comprend en outre un mécanisme d'affichage de l'heure 37 dérivé du rouage de finissage 31, ce mécanisme étant associé à un mécanisme de mise à l'heure 30, comme cela est montré sur la figure 5. Un mécanisme d'affichage de l'heure sera décrit en détail plus bas.As shown in the figures, the movement of the timepiece 1 comprises a carousel 4. This carousel is formed of a platform 5 carrying an escape wheel 6 cooperating with a balance spring 7. A finishing gear 31 is engaged with a crown wheel 17 carried by a barrel 18 as can be seen on the figure 3 . The movement further includes a time display mechanism 37 derived from the work train 31, which mechanism is associated with a time setting mechanism 30, as shown in FIG. figure 5 . A mechanism for displaying the time will be described in detail below.

Selon l'invention des premiers moyens sont mis en oeuvre pour entraîner la plate-forme 5 à partir du mécanisme d'affichage de l'heure 37. Cela est fondamentalement nouveau. En effet si l'on veut faire jouer au carrousel 4 un rôle d'indicateur de temps en plus de celui qui consiste de façon classique à corriger les erreurs de marche dues à la gravité, comme on l'a dit plus haut, il est nécessaire de pouvoir mettre à l'heure ledit indicateur en même temps qu'on met à l'heure les indicateurs ou aiguilles d'heures 2 et de minutes 3. Cela ne se présente pas dans le carrousel classique où la plate-forme est entraînée par le rouage de finissage qui est étranger au mécanisme d'affichage de l'heure 37. En fait dans la présente invention la plate-forme 5 est entraînée par le rouage d'affichage lié aux aiguilles indicatrices du temps.According to the invention first means are implemented to drive the platform 5 from the time display mechanism 37. This is fundamentally new. Indeed, if we want to play the carousel 4 a role of time indicator in addition to the one that consists in a conventional way to correct the errors of travel due to gravity, as mentioned above, it is It is necessary to be able to set the indicator at the same time as the indicators or hour hands 2 and minutes 3 are set. This does not occur in the conventional carousel where the platform is driven. by the finishing gear which is foreign to the time display mechanism 37. In fact in the present invention the platform 5 is driven by the display gear linked to the indicator hands of the time.

Toujours selon l'invention des seconds moyens sont mis en oeuvre pour entraîner la roue d'échappement 6 à partir du rouage de finissage 31 comme cela est explicité sur la figure 3 et décrit par la suite. On notera qu'on entend par rouage de finissage l'ensemble des roues et des pignons qui, du barillet 18, transmet la force motrice à la roue d'échappement 6.Still according to the invention second means are used to drive the escape wheel 6 from the gear train 31 as this is explained on the figure 3 and described later. It will be noted that the term "finishing gear" means all the wheels and gears which, from the barrel 18, transmit the driving force to the escape wheel 6.

Comme on le voit sur les figures 5 et 6, le mécanisme d'affichage de l'heure 37 utilisé ici n'est pas nouveau. II comporte une roue à canon ou roue des heures 9 portant un indicateur ou aiguille d'heure 2 - voir figure 1 - et une chaussée 10 portant un indicateur ou aiguille de minute 3 - voir figure 1. La roue à canon 9 et la chaussée 10 sont reliées cinématiquement par un mobile de minuterie 8.As we see on the figures 5 and 6 the time display mechanism 37 used here is not new. It comprises a clock wheel or hour wheel 9 carrying a flag or hour hand 2 - see figure 1 - and a roadway 10 carrying an indicator or minute hand 3 - see figure 1 . The gun wheel 9 and the roadway 10 are connected kinematically by a timer wheel 8.

Plus particulièrement comme le montrent les figures 5 à 7 le mobile de minuterie 8 comporte un premier pignon 13 en prise avec la roue à canon 9. Ce mobile comporte aussi une roue 14 en prise avec la chaussée 10. En plus de cela, la minuterie 8 porte un second pignon 15 qui est nouveau et qui est arrangé pour entraîner une denture 16 qui est solidaire de la plate-forme 5 et qui est disposée à sa périphérie, comme cela est représenté sur les figures 3, 6 et 7.More particularly as shown by Figures 5 to 7 the mobile timer 8 comprises a first pinion 13 engaged with the barrel wheel 9. This mobile also comprises a wheel 14 engaged with the road 10. In addition to this, the timer 8 carries a second pinion 15 which is new and which is arranged to drive a toothing 16 which is integral with the platform 5 and which is disposed at its periphery, as shown on the figures 3 , 6 and 7 .

Comme on l'a dit plus haut, le mobile de minuterie 8 est associé au mécanisme de mise à l'heure 30. Ce dernier est composé entre autres et de manière connue d'une tige de mise à l'heure 32 - qui est aussi la tige du remontoir -, d'un pignon de remontoir 33, d'un pignon coulant 34, d'un premier renvoi de minuterie 35 et d'un second renvoi de minuterie 36 lequel est en prise avec le mobile de minuterie 8 par l'engrènement d'un pignon 38 avec la roue 14 de la minuterie 8.As mentioned above, the timer mobile 8 is associated with the time setting mechanism 30. The latter is composed inter alia and in a known manner of a time-setting rod 32 - which is also the winding stem -, a winding pinion 33, a sliding pinion 34, a first timer return 35 and a second timer return 36 which is engaged with the timer wheel 8 by the meshing of a pinion 38 with the wheel 14 of the timer 8.

La plate-forme 5 est montée pivotante sur la platine 39 que possède la pièce d'horlogerie 1. Comme le montre la figure 3, sur un des côtés de la plate-forme un canon 40 est chassé dans ladite plate-forme 5. Ce canon pénètre dans une pierre 41 solidaire de la platine 39, pierre dans laquelle le canon peut tourner. Sur l'autre de ses côtés, la plate-forme 5 porte un pont 28 de balancier 7 qui porte à son tour un pivot 42 tournant dans une pierre 43 portée par un pont 44 fixé sur la platine 39.The platform 5 is pivotally mounted on the plate 39 that has the timepiece 1. As shown in FIG. figure 3 , on one side of the platform a gun 40 is driven into said platform 5. This gun penetrates a stone 41 secured to the plate 39, stone in which the barrel can rotate. On the other of its sides, the platform 5 carries a bridge 28 of balance 7 which in turn carries a pivot 42 rotating in a stone 43 carried by a bridge 44 fixed on the plate 39.

Dans ce mode d'exécution, la roue d'échappement 6 est située au centre de rotation de la plate-forme 5. Cette roue 6 est portée par un arbre 21 traversant le canon 40. L'arbre 21 pivote d'une part dans une pierre 45 portée par le pivot 42 et d'autre part dans une pierre 47 portée par un pont de rouage 46. La roue d'échappement 6 coopère directement avec une ancre - non représentée au dessin - dont la fourchette coopère avec une cheville 48 de plateau, ce dernier étant porté par l'arbre 27 du balancier 7. L'arbre 27 du balancier 7 pivote d'une part dans la plate-forme 5 et d'autre part dans le pont de balancier 28, ce dernier servant, comme on le verra plus loin d'indicateur de vingt-quatre heures.In this embodiment, the escape wheel 6 is located at the center of rotation of the platform 5. This wheel 6 is carried by a shaft 21 passing through the barrel 40. The shaft 21 pivots firstly in a stone 45 carried by the pivot 42 and secondly in a stone 47 carried by a gear wheel 46. The escapement wheel 6 cooperates directly with an anchor - not shown in the drawing - whose fork cooperates with an ankle 48 plate, the latter being carried by the shaft 27 of the balance 7. The shaft 27 of the balance 7 pivots on the one hand in the platform 5 and on the other hand in the balance bridge 28, the latter serving, as will be seen further from a twenty-four hour indicator.

Si l'on revient maintenant au rouage de finissage 31 dont on a parlé plus haut, on constate qu'il comporte au début de son développement, un pignon de centre 11 en prise directe avec la roue de couronne 17 portée par le barillet 18. Comme le montre bien la figure 3 la chaussée 10 est emmanchée à frottement gras sur le pignon de centre 11. Le pignon de centre 11 est muni d'une roue de centre 12 qui est en prise avec un train d'engrenage 19 entraînant à son tour la roue d'échappement 6 et cela via un pignon 20 porté par l'arbre 21 sur lequel est emmanchée ladite roue d'échappement 6. Le train d'engrenage 19 est composé de plusieurs mobiles pivotant d'une part dans la platine 39 et d'autre part dans le pont de rouage 46 dont on a parlé plus haut.Returning now to the finishing gear train 31 mentioned above, it is noted that it comprises at the beginning of its development, a center pinion 11 in direct contact with the crown wheel 17 carried by the barrel 18. As the figure 3 the roadway 10 is frictionally fitted on the center pinion 11. The center pinion 11 is provided with a center wheel 12 which is engaged with a gear train 19 which in turn drives the escape wheel 6 and this via a pinion 20 carried by the shaft 21 on which is fitted said exhaust wheel 6. The gear train 19 is composed of several mobile pivoting firstly in the plate 39 and secondly in the gear bridge 46 mentioned above.

On remarquera ici que l'invention n'est pas limitée à un rouage de finissage incluant un pignon de centre. Dans le cas par exemple où l'on désirerait pourvoir le mouvement d'un indicateur de seconde au centre, le rouage de finissage devrait inclure un pignon de grande moyenne et une roue de moyenne avant l'attaque du pignon de seconde.It will be noted here that the invention is not limited to a finishing gear including a center pinion. In the case, for example, where one would wish to provide the movement of a second indicator in the center, the finishing gear train should include a pinion of medium and a wheel of average before the attack of the second pinion.

On a dit plus haut que le carrousel de l'invention, en plus de compenser les différences de marche dues à la gravité, propose un rôle nouveau et complémentaire : celui d'indicateur de temps. Une forme d'exécution de la présente invention propose un affichage de vingt-quatre heures, d'autres temps pouvant être envisagés.It has been said above that the carousel of the invention, in addition to compensating for differences in travel due to gravity, proposes a new and complementary role: that of time indicator. An embodiment of the present invention provides a display of twenty-four hours, other times may be envisaged.

On signalera ici qu'un affichage de vingt-quatre heures sous forme de disque a déjà été proposé par exemple dans le document CH 671 317 où un disque d'affichage de périodes diurnes et nocturnes apparaissant au travers d'un cadran est entraîné par la roue à canon de la pièce d'horlogerie. II ne s'agit cependant pas là d'un disque carrousel.It will be noted here that a twenty-four hour display in the form of a disc has already been proposed for example in the document CH 671 317 wherein a display disc of diurnal and nocturnal periods appearing through a dial is driven by the watch wheel of the timepiece. However, this is not a carousel disk.

Pour permettre cet affichage, le rapport de transmission résultant de l'engrènement du second pignon 15 du mobile de minuterie 8 sur la denture 16 de la plate-forme 5 est choisi de telle façon que la plate-forme 5 fasse un tour en vingt-quatre heures.To enable this display, the transmission ratio resulting from the meshing of the second pinion 15 of the timer wheel 8 on the toothing 16 of the platform 5 is chosen so that the platform 5 makes a turn in twenty-five hours. four hours.

Dans ce cas et comme on l'a dit plus haut, le balancier 7, porté par son arbre 27 qui pivote d'une part dans la plate-forme 5 et d'autre part dans le pont 28 de balancier, utilise ce dernier comme indicateur de vingt-quatre heures. Le pont de balancier est ainsi utilisé comme aiguille de vingt-quatre heures se déplaçant en face de repères apposés sur le cadran ou la boîte de la pièce d'horlogerie.In this case and as mentioned above, the rocker 7, carried by its shaft 27 which pivots on the one hand in the platform 5 and on the other hand in the bridge 28, uses the latter as twenty-four hour indicator. The balance bridge is thus used as a twenty-four hour hand moving in front of marks affixed to the dial or the timepiece box.

Pour compléter ce qui vient d'être dit, la plate-forme 5 peut être surmontée d'un décor 22 duquel émerge le balancier 7. Comme le montre la figure 1, ce décor 22 peut apparaître partiellement à travers au moins une ouverture 23 pratiquée à douze heures dans le cadran 24 de la pièce d'horlogerie 1.To complete what has just been said, the platform 5 can be surmounted by a decoration 22 from which emerges the pendulum 7. As shown in FIG. figure 1 this decoration 22 may appear partially through at least one opening 23 made at twelve o'clock in the dial 24 of the timepiece 1.

Les figures 1, 4 et 6 montrent encore que la plate-forme 5 et son décor 22 font apparaître à travers l'ouverture 23 du cadran 24 les périodes diurnes et nocturnes du jour. Ici, le balancier 7 figure le soleil soit la période diurne du jour. La partie opposée au balancier porte sur le décor 22 une lune 25 et des étoiles 26 qui figurent la période nocturne du jour.The figures 1 , 4 and 6 show again that the platform 5 and its decoration 22 show through the opening 23 of the dial 24 the day and night periods of the day. Here, the pendulum 7 represents the sun, which is the daytime period of the day. The opposite part of the pendulum is on the decoration 22 a moon 25 and stars 26 which represent the night period of the day.

On a dit ci-dessus qu'une forme d'exécution de l'invention propose de situer la roue d'échappement 6 au centre de rotation de la plate-forme 5 ce qui n'est pas l'usage des carrousels connus où le balancier et la roue d'échappement s'opposent diamétralement. Une roue d'échappement centrée a pour conséquence un agrandissement du diamètre de la plate-forme ce qui est favorable du point de vue esthétique de la pièce d'horlogerie, surtout s'il s'agit d'une pièce de forme présentant une configuration ovale.It has been said above that one embodiment of the invention proposes to locate the escape wheel 6 at the center of rotation of the platform 5 which is not the use of known carousels where the balance and the escape wheel oppose diametrically. A centered escape wheel results in an enlargement of the diameter of the platform which is favorable from an aesthetic point of view of the timepiece, especially if it is a shaped piece having an oval configuration.
