Description

La présente invention se rapporte à un mouvement d'horlogerie comprenant une source d'énergie destinée à entretenir le mouvement oscillant d'un oscillateur mécanique par le biais d'un rouage de finissage comprenant un dispositif de régulation.The present invention relates to a watch movement comprising a power source for maintaining the oscillating movement of a mechanical oscillator by means of a finishing gear comprising a regulating device.

De tels mouvements sont connus depuis longtemps, notamment dans le domaine des horloges, pour permettre l'utilisation d'un ressort offrant une réserve de marche importante, en tant que source d'énergie, tout en lissant les inévitables variations de la force appliquée par ce ressort au rouage du mouvement, celles-ci découlant de la modification de l'état de charge du ressort au cours du fonctionnement de l'horloge.Such movements have been known for a long time, particularly in the field of clocks, to allow the use of a spring with a large power reserve, as a source of energy, while smoothing the inevitable variations in the force applied by this spring to the work train, these arising from the change in the state of charge of the spring during the operation of the clock.

Ainsi un certain nombre de mécanismes ont déjà été proposés faisant intervenir un ressort secondaire qui est chargé, à partir de l'énergie du ressort principal, de manière périodique. Cette période est suffisamment courte pour que la force qu'il applique au mouvement puisse être considérée comme étant constante entre ses états de charge minimale et de charge maximale.Thus, a number of mechanisms have already been proposed involving a secondary spring which is loaded, from the energy of the main spring, periodically. This period is sufficiently short for the force it applies to the movement to be considered constant between its states of minimum load and maximum load.

On parle alors de dispositifs à force constante, plus particulièrement lorsque le ressort secondaire est agencé directement au niveau de l'échappement, tandis qu'on parle de remontoir d'égalité lorsque le ressort secondaire est mis en place au niveau du rouage de finissage.This is called constant force devices, especially when the secondary spring is arranged directly at the exhaust, while it speaks of equal winding when the secondary spring is set up at the level of the gear train.

CH709394 décrit un mouvement d'horlogerie comprenant une source d'énergie mécanique, deux ensembles de régulation, chaque ensemble de régulation comprenant un échappement et un organe réglant. Le mouvement d'horlogerie comporte en outre un dispositif de partage de couple comportant autant d'organes élastiques que d'ensembles de régulation avec une entrée reliée à la source d'énergie mécanique, permettant la transmission de l'énergie produite par la source d'énergie mécanique aux ensembles de régulation. Chaque ensemble de régulation est entraîné par un organe élastique prévu jusqu'au mobile l'échappement. CH709394 discloses a clockwork comprising a mechanical power source, two control assemblies, each control assembly comprising an exhaust and a regulating member. The watch movement further comprises a torque-sharing device comprising as many elastic members as regulation assemblies with an input connected to the source of mechanical energy, enabling the transmission of the energy produced by the source of power. mechanical energy to the control assemblies. Each regulation assembly is driven by an elastic member provided until the mobile exhaust.

La présente invention a pour but principal de proposer une amélioration aux mécanismes connus de l'art antérieur, en proposant un mouvement pour pièce d'horlogerie comportant un dispositif de régulation dont la construction permet d'améliorer la chronométrie en distribuant un couple constant en perturbant le moins possible l'échappement.The main object of the present invention is to propose an improvement to the mechanisms known from the prior art, by proposing a movement for a timepiece comprising a regulating device whose construction makes it possible to improve chronometry by distributing a constant torque while disturbing the least possible escape.

Conformément à l'invention, un mouvement d'horlogerie mécanique comprend une source d'énergie mécanique, notamment un barillet, entrainant un organe réglant composé d'un balancier-spiral, dont le mouvement oscillant est entretenu par la source d'énergie. Le mouvement comprend en outre un dispositif de régulation disposé entre la source d'énergie et un échappement associé audit organe réglant, le dispositif de régulation comportant une liaison élastique agencée pour commander l'échappement. La liaison élastique comporte un ressort spiral dont une extrémité est reliée au dispositif de régulation et l'autre extrémité est reliée à un dispositif de déclenchement agencé de manière à ce que le dispositif de déclenchement est libéré de manière périodique par le dispositif de régulation.According to the invention, a mechanical clockwork movement comprises a source of mechanical energy, in particular a barrel, driving a regulating member composed of a balance spring, the oscillating movement of which is maintained by the energy source. The movement further comprises a regulating device disposed between the energy source and an exhaust associated with said regulating member, the regulating device comprising an elastic connection arranged to control the escapement. The elastic connection comprises a spiral spring whose one end is connected to the regulating device and the other end is connected to a triggering device arranged in such a way that the triggering device is released periodically by the regulating device.

Dans une forme d'exécution, le dispositif de régulation comporte une roue de secondes en prise cinématique avec le rouage du dispositif d'arrivée d'énergie, et un pignon d'échappement qui relie la roue de secondes à l'échappement. La roue des secondes est reliée à la seconde extrémité du ressort spiral.In one embodiment, the regulating device comprises a second wheel in kinematic engagement with the work train of the energy supply device, and an escape pinion which connects the seconds wheel to the exhaust. The seconds wheel is connected to the second end of the spiral spring.

Selon la même forme d'exécution, une roue supplémentaire est portée par le pignon d'échappement. Le pignon d'échappement engrène avec un pignon supplémentaire portant une came de déclenchement qui commande une ancre de déclenchement agencée pour libérer périodiquement la roue de déclenchement.According to the same embodiment, an additional wheel is carried by the exhaust pinion. The escape pinion meshes with an additional pinion carrying a trigger cam which controls a trigger anchor arranged to periodically release the trigger wheel.

Selon cette forme d'exécution, la came de déclenchement est solidaire en rotation de la roue d'échappement.According to this embodiment, the trip cam is integral in rotation with the escape wheel.

Dans une autre forme d'exécution, la came de déclenchement est solidaire de la roue d'échappement.In another embodiment, the trip cam is integral with the escape wheel.

De préférence, le dispositif de déclenchement est agencé pour être libéré par le dispositif de régulation toutes les secondes.Preferably, the triggering device is arranged to be released by the regulator every second.

Dans une forme d'exécution, le dispositif de régulation comporte une seconde liaison élastique sous forme d'un second ressort spiral agencé pour commander un second organe réglant. Dans cet exemple, le dispositif de déclenchement commande soit le premier ressort spiral soit le second ressort spiral.In one embodiment, the regulating device comprises a second elastic connection in the form of a second spiral spring arranged to control a second regulating member. In this example, the tripping device controls either the first spiral spring or the second spiral spring.

Selon cette forme d'exécution, le premier ressort spiral, le second ressort spiral et une roue du dispositif de déclenchement sont agencées coaxialement autour d'un axe.According to this embodiment, the first spiral spring, the second spiral spring and a wheel of the trigger device are arranged coaxially about an axis.

Dans une autre forme d'exécution, un premier dispositif de déclenchement commande un premier ressort spiral agencé pour commander un premier organe réglant. Un second dispositif de déclenchement commande un second ressort spiral agencé pour commander un second organe réglant. Un mécanisme différentiel coopérant avec la source d'énergie est agencée pour fournir de l'énergie à chacun des premiers et seconds ressorts spiraux.In another embodiment, a first triggering device controls a first spiral spring arranged to control a first regulating member. A second triggering device controls a second spiral spring arranged to control a second regulating member. A differential mechanism cooperating with the power source is arranged to supply power to each of the first and second coil springs.

Les caractéristiques de l'invention apparaitront plus clairement à la lecture de la description de plusieurs formes d'exécution données uniquement à titre d'exemple, nullement limitative en se référant aux figures schématiques, dans lesquelles :

  • La figure 1 représente une vue en perspective d'un mouvement de montre comportant un dispositif de régulation comprenant deux mobiles de seconde agencés l'un au-dessus de l'autre, deux balanciers-spiraux excentrés l'un par rapport à l'autre et un dispositif de déclenchement ;

  • La figure 5 représente une vue en perspective d'un mouvement de montre comportant deux dispositifs de régulation et un mécanisme différentiel agencé pour coopérer avec chacun des dispositifs de régulation.
The characteristics of the invention will appear more clearly on reading the description of several embodiments given solely by way of example, in no way limiting with reference to the schematic figures, in which:
  • The figure 1 represents a perspective view of a watch movement comprising a regulating device comprising two second movables arranged one above the other, two eccentric balance-springs eccentric with respect to each other and a device triggering;
  • The figure 2 represents a bottom view of a regulating device according to the invention;

  • The figure 5 represents a perspective view of a watch movement comprising two regulating devices and a differential mechanism arranged to cooperate with each of the regulating devices.

Comme illustré à la figure 1, un mouvement d'horlogerie mécanique, notamment pour une montre-bracelet, comprend un barillet 1, entrainant deux balanciers-spiraux 4, 5. Un dispositif de régulation 7, 8, 80 est disposé entre le barillet 1, et les échappements 2, 3 associés à chacun des balanciers-spiraux 4, 5. Le dispositif de régulation 7, comporte deux ressorts spiraux 8, 80 agencés pour commander les échappements 2, 3. Le premier ressort spiral 8 est relié à une extrémité 8A (figure 2) au dispositif d'arrivée d'énergie 9, et l'autre extrémité 8B (figure 2) est reliée au dispositif de régulation 7, 8 agencé de manière à ce que le dispositif d'arrivée d'énergie 9 est libéré de manière périodique par le dispositif de déclenchement 6, 10, 11, 12, 13. Dans cet exemple, les ressorts spiraux 8, 80 sont concentriques et seul l'échappement 2 pilote le déclenchement et réarme les deux ressorts spiraux 8, 80,As illustrated in figure 1 , a mechanical clockwork movement, in particular for a wristwatch, comprises a barrel 1, driving two balance-springs 4, 5. A regulating device 7, 8, 80 is disposed between the barrel 1, and the escapements 2, 3 associated with each of the balance springs 4, 5. The regulating device 7 comprises two spiral springs 8, 80 arranged to control the escapements 2, 3. The first spiral spring 8 is connected to one end 8A (FIG. figure 2 ) to the energy supply device 9, and the other end 8B ( figure 2 ) is connected to the control device 7, 8 arranged in such a way that the energy supply device 9 is periodically released by the triggering device 6, 10, 11, 12, 13. In this example, the spiral springs 8, 80 are concentric and only the escapement 2 controls the triggering and resets the two spiral springs 8, 80,

Comme illustré à la figure 2, le dispositif de régulation comporte deux roues de seconde 7 coaxiales et montées libres sur un pignon de seconde 9, une seule des roues de seconde 7 étant visible sur ladite figure 2. La roue de seconde 7 coopère avec un pignon d'échappement 14 pour relier la roue de seconde 7 à l'échappement 2. Le pignon de seconde 9 porte une roue de déclenchement 6 et l'extrémité intérieure 8A d'un ressort-spiral 8. La roue de seconde 7 est montée libre et est reliée à la seconde extrémité libre, extrémité extérieure 8B, du ressort spiral 8. Lors du montage, un pré-armage est donné au ressort spiral 8 de manière à ce qu'il puisse fournir le couple nécessaire à l'entretien des oscillations d'un balancier. Cette roue de seconde 7 engrène avec le pignon d'échappement 14 qui porte la roue d'échappement 2 ainsi qu'une roue supplémentaire 12. La roue d'échappement 2 travaille avec une ancre comme c'est usuel dans un mouvement mécanique traditionnel. La roue supplémentaire 12 entraine un pignon supplémentaire 13 portant une came de déclenchement 11 qui pilote une ancre de déclenchement 10.As illustrated in figure 2 , the regulation device comprises two coaxial second wheels 7 mounted free on a second pinion 9, only one of the second wheels 7 being visible on said figure 2 . The second wheel 7 cooperates with an escape gear 14 to connect the second wheel 7 to the exhaust 2. The second gear 9 carries a trigger wheel 6 and the inner end 8A of a spiral spring 8 The second wheel 7 is mounted free and is connected to the second free end, outer end 8B, of the spiral spring 8. During assembly, a pre-arming is given to the spiral spring 8 so that it can provide the torque needed to maintain the oscillations of a pendulum. This second wheel 7 meshes with the exhaust pinion 14 which carries the escape wheel 2 and an additional wheel 12. The escape wheel 2 works with an anchor as is usual in a traditional mechanical movement. The additional wheel 12 drives an additional pinion 13 carrying a trigger cam 11 which controls a trigger anchor 10.

Dans l'exemple illustré à la figure 3, le dispositif de régulation comporte deux roues de seconde 7 portées par un pignon de secondes 9. Le pignon de seconde 9 porte également une roue de déclenchement 6 et la partie intérieure 8A d'un ressort-spiral 8. Chacune des roues de seconde 7 est reliée à la seconde extrémité libre du spiral, respectivement 8B du ressort spiral 8 et 80B du ressort spiral 80. La roue de déclenchement 6 commande le réarmage des deux ressorts spiraux 8, 80. Selon cette configuration, l'énergie provenant du barillet est transmise au pignon de seconde 9, solidaire de la roue de déclenchement 6 et des extrémités intérieures 8A, 80A des ressorts spiraux 8, 80. Les ressorts spiraux 8, 80, pré-armés au montage, comportent des extrémités externes 8B, 80B solidaires des roues de seconde 7 entrainant chacune un balancier-spiral 4,5.In the example shown in figure 3 the control device comprises two second wheels 7 carried by a pinion of seconds 9. The second pinion 9 also carries a trigger wheel 6 and the inner portion 8A of a spiral spring 8. Each of the second wheels 7 is connected to the second free end of the spiral, respectively 8B of the spiral spring 8 and 80B of the spiral spring 80. The trigger wheel 6 controls the rearming of the two spiral springs 8, 80. According to this configuration , the energy from the barrel is transmitted to the second pinion 9, integral with the trigger wheel 6 and the inner ends 8A, 80A of the spiral springs 8, 80. The spiral springs 8, 80, pre-armed assembly, comprise outer ends 8B, 80B secured to the second wheels 7 each driving a balance spring-balance 4,5.

Dans l'exemple illustré à la figure 4, le principe est le même que le mécanisme illustré à la figure 1, à la différence que les balanciers-spiraux 4, 5, dans cet exemple, sont disposés l'un au-dessus de l'autre. Le barillet 1 transmet cinématiquement l'énergie au pignon de seconde 9, solidaire des extrémités intérieures 8A, 80A des ressorts spiraux 8, 80. L'extrémité externe 80B du ressort spiral 80, solidaire d'une première roue de seconde 7 entraine l'échappement 3 et le balancier-spiral 5. L'extrémité externe 8B du ressort spiral 8, solidaire d'une seconde roue de seconde 7 entraine l'échappement 2, la roue supplémentaire 12 et le balancier-spiral 4. La roue supplémentaire 12 entraine le pignon supplémentaire 13 portant la came de déclenchement 11 qui pilote l'ancre de déclenchement 10. L'ancre de déclenchement libère alors la roue de déclenchement 6 solidaire du pignon de seconde 9.In the example shown in figure 4 , the principle is the same as the mechanism illustrated in figure 1 with the difference that the balance springs 4, 5, in this example, are arranged one above the other. The barrel 1 transmits kinematically the energy to the second pinion 9, secured to the inner ends 8A, 80A of the spiral springs 8, 80. The outer end 80B of the spiral spring 80, integral with a first wheel of the second 7 drives the Exhaust 3 and the sprung balance 5. The outer end 8B of the spiral spring 8, secured to a second second wheel 7 causes the exhaust 2, the additional wheel 12 and the sprung balance 4. The additional wheel 12 leads the additional gear 13 carrying the trip cam 11 which controls the trigger anchor 10. The trigger anchor then releases the trigger wheel 6 integral with the second gear 9.

Ainsi, dans ces deux exemples, le second ressort spiral 80 et la seconde roue de seconde 7 donnent la force au second balancier 5 spiral mais seul un des deux mobiles d'échappement 2, 3 commande le déclenchement.Thus, in these two examples, the second spiral spring 80 and the second second wheel 7 give the force to the second balance spring 5 but only one of the two escape mobiles 2, 3 controls the trigger.

Dans l'exemple illustré à la figure 5, un premier dispositif de déclenchement 6, 10, 11, 12, 13 commande un premier ressort spiral 8 agencé pour commander un premier balancier-spiral 4. Un second dispositif de déclenchement 6, 10, 11, 12, 13 commande un second ressort spiral 80 agencé pour commander un second balancier-spiral 5. Un mécanisme différentiel 20 coopère avec le barillet 1 pour fournir de l'énergie à chacun des premiers et seconds ressorts spiraux 8, 80 via le pignon de seconde 9. Dans cet exemple où les deux dispositifs de régulations sont montés en parallèle, le mécanisme différentiel est agencé dans la roue de moyenne 20 de manière à recevoir en amont l'énergie du barillet 1 et de fournir l'énergie à chaque organe réglant 4, 5.In the example shown in figure 5 , a first trigger device 6, 10, 11, 12, 13 controls a first spiral spring 8 arranged to control a first balance-spring 4.
