L'invention concerne encore une montre comportant un tel mouvement d'horlogerie ou/et un tel mécanisme d'affichage.The invention also relates to a watch comprising such a watch movement or / and such a display mechanism.

L'invention concerne le domaine des mécanismes d'affichage d'horlogerie, en particulier pour des montres.The invention relates to the field of clock display mechanisms, in particular for watches.

Arrière-plan de l'inventionBackground of the invention

Les mouvements pourvus de mécanisme de quantième sont pourvu de différents mécanismes d'entraînement :

  • les mécanismes d'entraînement traînant ;
  • les mécanismes semi-instantanés ;
  • les mécanismes instantanés.
Movements equipped with a date mechanism are provided with different drive mechanisms:
  • trailing training mechanisms;
  • semi-instantaneous mechanisms;
  • the instantaneous mechanisms.

Un exemple de mécanisme traînant est décrit dans le livre « Les montres compliquées » de François Lecoultre (Ed. Simon in) sous les chapitres quantième simple et quantième perpétuels traînants.An example of a dragging mechanism is described in the book "Complicated watches" by François Lecoultre (Ed. Simon in) chapters simple calendar and perpetual calendar drawlers.

Les mécanismes semi-instantanés sont très répandus, car de construction simple, un doigt souple s'arme sur l'entraînement du quantième, jusqu'au saut du sautoir de quantième, seule la seconde partie du saut est de ce fait instantanée. Cette construction est présente sur les principaux mouvements du commerce, notamment 2824,2892 ETA, 7700, 1050, 7875 Breguet, 1150, 1180, 1280 Blancpain.The semi-instantaneous mechanisms are widespread, because of simple construction, a flexible finger is armed on the training of the date, until the jump of the date jumper, only the second part of the jump is thus instantaneous. This construction is present on the main movements of the trade, in particular 2824,2892 ETA, 7700, 1050, 7875 Breguet, 1150, 1180, 1280 Blancpain.

Un exemple de mécanisme instantané est décrit dans le livre « Les montres compliquées » de François Lecoultre (Ed. Simon in) sous le chapitre quantième perpétuel instantané. D'autre constructions existent avec des systèmes d'armage d'un ressort sur une partie de la journée et un déclenchement à minuit, qui libère le ressort et effectue la fonction d'entrainement du quantième. Des mouvements de ce type existent sur le marché, par exemple le mouvement 8810 Breguet ou le 6950 Blancpain.An example of an instantaneous mechanism is described in the book "Complicated watches" by François Lecoultre (Ed. Simon in) under the instant perpetual calendar chapter. Other constructions exist with reinforcement systems a spring on a part of the day and a trigger at midnight, which releases the spring and performs the training function of the date. Movements of this type exist on the market, for example the 8810 Breguet movement or the 6950 Blancpain.

Lors de la construction de mécanismes de quantième complexes instantanés, par exemple des quantièmes perpétuels ou à affichages à grands guichets ou à rouleaux, un déclenchement instantané engendre des vitesses élevées des composants. Les contraintes dynamiques appliquées aux composants deviennent sensibles en raison de leur inertie : une vitesse élevée, conjuguée à une forte inertie, génère des contraintes importantes, qui sont inexistantes dans le cas d'une fonction traînante (une à plusieurs heures de passage), et des perturbations de fonctionnement peuvent se produire, par exemple des doubles sauts peuvent être effectués.When building complex instantaneous date mechanisms, such as perpetual calendars or with large windows or roller displays, instantaneous tripping results in high component speeds. The dynamic stresses applied to the components become sensitive because of their inertia: a high speed, combined with a high inertia, generates important constraints, which are non-existent in the case of a dragging function (one to several hours of passage), and operating disturbances can occur, for example double jumps can be made.

La même problématique concerne d'autres affichages avec changement d'affichage par saut que le cas particulier décrit ci-dessus d'un affichage de quantième, par exemple des affichages AM/PM, ou jour/nuit, ou encore tout affichage rétrograde.The same problem concerns other displays with change of display by jump than the particular case described above of a date display, for example displays AM / PM, or day / night, or any retrograde display.

Résumé de l'inventionSummary of the invention

Pour un mécanisme d'affichage avec changement d'affichage par saut, tel que notamment et non limitativement un mécanisme de quantième complexe, tel que quantième perpétuel, ou quantième à affichage à grands guichets ou à rouleaux, il est intéressant d'avoir un passage de quantième à minuit, instantané, mais visible par l'utilisateur, pendant quelques secondes. Par exemple un passage du 28 février au premier mars en 3 à 4 secondes. Cette réduction de la notion d'instantané devient qualitative.For a display mechanism with change of display by jump, such as including and not limited to a complex date mechanism, such as perpetual calendar, or date display with large windows or roller, it is interesting to have a passage from date to midnight, instantaneous, but visible to the user, for a few seconds. For example a passage from February 28 to March 1 in 3 to 4 seconds. This reduction of the notion of snapshot becomes qualitative.

La présente invention se propose de développer un entraînement d'affichage régulé, dont le saut puisse être visible par l'utilisateur, et est plus particulièrement décrite pour un mécanisme d'affichage de quantième régulé.The present invention proposes to develop a regulated display drive, the jump of which can be seen by the user, and is more particularly described for a regulated date display mechanism.

A cet effet, l'invention concerne un mécanisme d'affichage d'horlogerie avec afficheur mobile par sauts, selon la revendication 1.To this end, the invention relates to a timepiece display mechanism with a mobile display according to claim 1.

Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

L'invention concerne un mécanisme d'affichage 1 d'horlogerie avec afficheur 100 mobile par sauts. Plus particulièrement cet afficheur est mobile par sauts périodiques. C'est le cas de la réalisation illustrée par les figures.The invention relates to a watchmaking display mechanism 1 with a display that is movable by jumps. More particularly, this display is mobile by periodic jumps. This is the case of the embodiment illustrated by the figures.

Ce mécanisme 1 comportant au moins un ressort 2 entre un premier mobile 4 et un deuxième mobile 30. Ce premier mobile 4, ou respectivement ce deuxième mobile 30, est agencé pour être entraîné par un mobile d'entraînement 201, que comporte, ou bien le mécanisme d'affichage lui-même, ou un mécanisme extérieur, tel qu'un mouvement 500 ou similaire.This mechanism 1 comprising at least one spring 2 between a first mobile 4 and a second mobile 30. This first mobile 4, or respectively the second mobile 30, is arranged to be driven by a drive wheel 201, that includes, or the display mechanism itself, or an external mechanism, such as a movement 500 or the like.

Selon l'invention, le mobile qui n'est pas entraîné directement par le mobile d'entraînement 201, c'est-à-dire le deuxième mobile 30, ou respectivement le premier mobile 4, est agencé pour entraîner ou porter une came 5.According to the invention, the mobile that is not driven directly by the driving wheel 201, that is to say the second mobile 30, or respectively the first mobile 4, is arranged to drive or carry a cam 5 .

Plus particulièrement, cette came 5 est une came périphérique en colimaçon 51, qui est parcourue par un palpeur 6, lequel est agencé pour commander le saut, et notamment le saut périodique, d'un tel afficheur 100.More particularly, this cam 5 is a peripheral spiral cam 51, which is traversed by a probe 6, which is arranged to control the jump, and in particular the periodic jump, of such a display 100.

Et le mécanisme 1 comporte des moyens de verrouillage/déclenchement 70, qui comportent, d'une part au moins un doigt 7 entraîné par le deuxième mobile 30, ou respectivement le premier mobile 4, et d'autre part un troisième mobile 80 qui est agencé pour, selon sa position angulaire, arrêter ou libérer cet au moins un doigt 7, pour interdire ou respectivement autoriser la rotation de la came 5.And the mechanism 1 comprises locking / triggering means 70, which comprise, on the one hand at least one finger 7 driven by the second mobile 30, respectively the first mobile 4, and on the other hand a third mobile 80 which is arranged to, according to its angular position, stop or release this at least one finger 7, to prohibit or respectively allow the rotation of the cam 5.

La fonction de cette came 5 est d'imposer une certaine durée de parcours du palpeur 6, pour réaliser un changement d'affichage, de façon bien visible par l'utilisateur: le saut s'étale ainsi sur une durée de quelques secondes, correspondant au plus long parcours possible en périphérie de la came.The function of this cam 5 is to impose a certain duration of travel of the probe 6, to achieve a change of display, clearly visible by the user: the jump is spread over a period of a few seconds, corresponding at the longest possible distance on the periphery of the cam.

De façon à ce que ce changement d'affichage s'effectue de la façon la plus uniforme possible, de façon avantageuse, le mécanisme 1 comporte un mécanisme de régulation 9 pour réguler la vitesse de rotation du mobile qui porte la came 5 : ce mécanisme de régulation 9 comporte notamment, dans la version illustrée, un rouage de régulation, qui engrène avec celui du deuxième mobile 30, ou respectivement du premier mobile 4 qui entraîne ou porte la came 5) pour limiter sa vitesse de rotation quand le doigt 7 est libéré.So that this display change is carried out in the most uniform way possible, advantageously, the mechanism 1 comprises a regulating mechanism 9 for regulating the rotational speed of the mobile carrying the cam 5: this mechanism 9 in the illustrated version includes a control gear, which meshes with that of the second mobile 30, or respectively the first mobile 4 which drives or carries the cam 5) to limit its speed of rotation when the finger 7 is released.

Plus particulièrement, dans la réalisation non limitative illustrée par les figures, le mécanisme 1 comporte au moins un ressort 2 enroulé entre, d'une part un arbre 41 du premier mobile 4, et d'autre part le deuxième mobile 30. Plus particulièrement encore, ce deuxième mobile 30 est un tambour 3, qui porte au moins un doigt 7 périphérique, sans interférence avec la trajectoire du palpeur 6, et notamment extérieur à la trajectoire du palpeur 6. Ce tambour 3 porte une came 5 périphérique, laquelle comporte, plus particulièrement, au moins un seuil de remise à zéro 52 après un saut de l'afficheur 100, et est, plus particulièrement mais non nécessairement, un colimaçon 51. La came 5 est parcourue par un palpeur 6 agencé pour commander le saut, notamment le saut périodique, d'un afficheur 100, notamment mais non limitativement de quantième.More particularly, in the non-limiting embodiment illustrated by the figures, the mechanism 1 comprises at least one spring 2 wound between, on the one hand a shaft 41 of the first mobile 4, and secondly the second mobile 30. More particularly still , this second mobile 30 is a drum 3, which carries at least one peripheral finger 7, without interference with the trajectory of the probe 6, and in particular outside the trajectory of the probe 6. This drum 3 carries a peripheral cam 5, which comprises, more particularly, at least one resetting threshold 52 after a jump of the display 100, and is, more particularly but not necessarily, a spiral 51. The cam 5 is traversed by a probe 6 arranged to control the jump, in particular the periodic jump, a display 100, including but not limited to calendar.

Dans la réalisation illustrée, le colimaçon 51 comporte une longue rampe, qui s'étend depuis un niveau inférieur 511 vers un niveau supérieur 512, et un seuil 52 unique. Le palpeur 6 est un galet dans la variante non limitative illustrée par les figures. Dans d'autres variantes non illustrées, ce palpeur peut être un simple doigt frottant sur le profil de came, ou autre.In the embodiment illustrated, the spiral 51 comprises a long ramp, which extends from a lower level 511 to a higher level 512, and a single threshold 52. The probe 6 is a roller in the non-limiting variant illustrated by the figures. In other variants not shown, this probe may be a simple finger rubbing on the cam profile, or other.

Dans d'autres variantes non illustrées, le colimaçon peut comporter, sur sa circonférence, une alternance de telles rampes et de tels seuils. Plus particulièrement et non limitativement, le secteur angulaire correspondant à chaque rampe est identique.In other variants not shown, the spiral may comprise, on its circumference, an alternation of such ramps and such thresholds. More particularly and not exclusively, the angular sector corresponding to each ramp is identical.

Dans les réalisations illustrées, le troisième mobile 80 est un arrêtoir, et en particulier une ancre 8, qui est mobile angulairement autour d'un axe d'ancre D8 sous l'action du premier mobile 4, ou respectivement du deuxième mobile 30. Cette ancre 8 est agencée pour, selon sa position angulaire, arrêter ou libérer cet au moins un doigt 7, pour interdire ou respectivement autoriser la rotation de la came 5.In the illustrated embodiments, the third mobile 80 is a stop, and in particular an anchor 8, which is angularly movable about an anchor axis D8 under the action of the first mobile 4 or the second mobile 30. This anchor 8 is arranged for, according to its angular position, stop or release this at least one finger 7, to prohibit or respectively allow the rotation of the cam 5.

Plus particulièrement, le premier mobile 4 comporte un maneton excentrique 42, qui guide en permanence une rainure 81, que comporte une ancre 8 de déclenchement, pour commander des va-et-vient périodiques de cette ancre 8 pivotante. Cette ancre 8 comporte, de part et d'autre de son axe d'ancre D8, un bec 83 et une butée 84 pour arrêter ou relâcher le doigt 7 selon la position angulaire de l'ancre 8.More particularly, the first mobile 4 comprises an eccentric crank pin 42, which permanently guides a groove 81, which comprises a trigger anchor 8, to control the reciprocating and back-and-forth 8 pivoting anchor. This anchor 8 comprises, on either side of its anchor axis D8, a spout 83 and a stop 84 for stopping or releasing the finger 7 according to the angular position of the anchor 8.

La course angulaire de chaque doigt 7 entre son relâchement par le bec 83 et son retour en appui sur la butée 84 définit la durée du saut, c'est-à-dire du changement d'affichage.The angular travel of each finger 7 between its release by the spout 83 and its return bearing on the stop 84 defines the duration of the jump, that is to say the change of display.

Dans le cas particulier illustré par les figures, le doigt 7 est unique.In the particular case illustrated by the figures, the finger 7 is unique.

Dans le cas particulier illustré par les figures, le seuil de remise à zéro 52 sur la came 5 est unique.In the particular case illustrated by the figures, the resetting threshold 52 on the cam 5 is unique.

Dans une application particulière de l'invention, illustrée par les figures, le mécanisme 1 comporte un barillet 10 comportant au moins un tel ressort 2 entre d'une part l'arbre du barillet 10, qui est solidaire avec l'arbre 41 du premier mobile 4, ou qui le constitue, et d'autre part le tambour 3.In a particular application of the invention, illustrated by the figures, the mechanism 1 comprises a barrel 10 comprising at least one such spring 2 between on the one hand the shaft of the barrel 10, which is integral with the shaft 41 of the first mobile 4, or which constitutes it, and on the other hand the drum 3.

Néanmoins ce ressort 2 peut aussi être n'importe quel ressort adéquat, le ressort de barillet n'est qu'un cas particulier, qui se prête bien à la mise en oeuvre industrielle de l'invention.However, this spring 2 can also be any suitable spring, the mainspring is only a special case, which lends itself well to the industrial implementation of the invention.

Dans l'exemple non limitatif illustré, l'armage du ressort 2 est effectué par un mobile d'entraînement 201, qui est une roue de 24 heures ou qui est relié dans un rouage à une roue de 24 heures. L'armage du ressort peut être réalisé par un autre moyen que la roue de 24h, par exemple un rouage d'automatique entraîné par une masse oscillante, un mécanisme de remontage manuel, ou autre.In the nonlimiting example illustrated, the armature of the spring 2 is performed by a drive wheel 201, which is a 24-hour wheel or is connected in a wheel to a wheel 24 hours. The arming of the spring can be achieved by means other than the 24 hour wheel, for example an automatic gear driven by an oscillating weight, a manual winding mechanism, or other.

Plus particulièrement, le premier mobile 4 est pivotant, et entraîné dans un rapport entier de vitesse par un mobile d'entraînement 201.More particularly, the first mobile 4 is pivotable, and driven in an entire gear ratio by a drive wheel 201.

Le mouvement de va-et-vient de l'ancre 8 définit une course angulaire, rapportée à l'axe D4 du premier mobile 4, de chaque doigt 7 entre son relâchement par le bec 83 et son retour en appui sur la butée 84. Cette course angulaire définit la durée de saut, qui correspond à la durée de la course du palpeur 6 sur la came 5, d'abord selon une rampe douce en montée progressive depuis un niveau inférieur 511 vers un niveau supérieur 512 du colimaçon 51 puis en redescente instantanée au niveau inférieur 511 lors du franchissement du seuil de remise à zéro 52. Ce retour à la position du niveau inférieur 511 par le flanc raide du seuil 52 se fait instantanément, et sans influencer l'affichage, par exemple grâce à un système de doigt cliquet sur une étoile, ou similaire.The reciprocating movement of the anchor 8 defines an angular stroke, related to the axis D4 of the first mobile 4, of each finger 7 between its release by the spout 83 and its return bearing on the abutment 84. This angular stroke defines the duration of the jump, which corresponds to the duration of the stroke of the feeler 6 on the cam 5, firstly according to a gentle ramp in gradual ascent from a lower level 511 to a higher level 512 of the spiral 51 then instantaneous lowering to the lower level 511 when crossing the reset threshold 52. This return to the position of the lower level 511 by the steep edge of the threshold 52 is instantaneous, and without influencing the display, for example through a system finger ratchet on a star, or the like.

Ainsi, chaque saut correspond à un changement d'état de l'afficheur 100 entre un état antérieur et un état postérieur, et la durée de saut correspond au laps de temps écoulé entre l'affichage stable de l'état antérieur et l'affichage stable de l'état postérieur.Thus, each jump corresponds to a change of state of the display 100 between an earlier state and a posterior state, and the jump duration corresponds to the lapse of time elapsed between the stable display of the previous state and the display. stable of the posterior state.

Plus particulièrement, le premier mobile 4 d'entrée est agencé pour être entraîné par un mobile d'entraînement en continu 201 et pour accomplir, pendant une révolution du mobile d'entraînement en continu 201, une révolution ou un nombre entier de tours ou une fraction entière de tour.More particularly, the first mobile 4 input is arranged to be driven by a continuous drive mobile 201 and to perform, during a continuous drive mobile revolution 201, a revolution or an integer number of turns or an entire fraction of a turn.

Une application particulière de l'invention est illustrée par les figures.A particular application of the invention is illustrated by the figures.

Le mobile d'entraînement 201 est une roue de 24 heures fournissant l'énergie, et la référence temporelle (un tour en 24 heures) d'un mouvement horloger classique.The drive wheel 201 is a 24-hour wheel providing the energy, and the time reference (a turn in 24 hours) of a conventional watch movement.

Ce mobile d'entraînement 201 entraine un premier mobile d'entrée 4, qui est ici une roue de 24 heures auxiliaire. Ce premier mobile d'entrée 4 porte un maneton excentrique 42, et son arbre 41 est relié à un ressort 2 de barillet 3 auxiliaire. Ce barillet auxiliaire 3 est donc, ici, armé d'un tour par 24 heures.This drive mobile 201 drives a first input mobile 4, which is here an auxiliary 24-hour wheel. This first input mobile 4 carries an eccentric crank pin 42, and its shaft 41 is connected to a spring 2 auxiliary barrel 3. This auxiliary barrel 3 is here, armed with a turn in 24 hours.

Le maneton excentrique 42 coopère en continu avec la rainure 81 de l'ancre 8, qui est une rainure oblongue droite dans le cas particulier des figures, de la roue de 24h aux. L'ancre de déclenchement 8 effectue de ce fait un va et vient en 24 heures. On comprend que l'exemple illustré concerne un saut journalier unique à minuit pour le cas particulier d'un quantième, mais il est possible d'extrapoler l'invention à tout affichage avec une autre période en jouant sur les rapports d'engrenage, le nombre de doigts 7 et leurs positions, le nombre de troisièmes mobiles 80, notamment d'ancres 8, le nombre de seuils de remise à zéro 52, pour effectuer d'autres commandes de sauts.The eccentric crank pin 42 cooperates continuously with the groove 81 of the anchor 8, which is a straight oblong groove in the particular case of the figures, of the wheel 24 hours. The trigger anchor 8 thus performs a come and go in 24 hours. It is understood that the illustrated example relates to a single daily jump at midnight for the particular case of a date, but it is possible to extrapolate the invention to any display with another period by adjusting the gear ratios, the number of fingers 7 and their positions, the number of third mobiles 80, including anchors 8, the number of resetting thresholds 52, to perform other jumping commands.

Par exemple une application avec deux sauts journaliers à midi et à minuit permet le changement d'état d'un indicateur AM/PM, ou une application avec deux sauts journaliers à 6 heures et à 18 heures permet le changement d'état d'un indicateur jour/nuit.For example an application with two daily jumps at noon and midnight allows the change of state of an AM / PM indicator, or an application with two daily jumps at 6 o'clock and at 18 o'clock allows the change of state of a day / night indicator.

Une autre application encore concerne un semainier, avec rotation de sept jours, et affichage du jour de la semaine. Bien d'autres applications sont accessibles et avantageuses à l'homme du métier, car l'invention procure une visibilité nouvelle des changements d'affichage, qui constitue un perfectionnement agréable pour l'utilisateur.Another application still concerns a weeklong, with rotation of seven days, and display of the day of the week. Many other applications are accessible and advantageous to those skilled in the art, because the invention provides a new visibility of display changes, which is a pleasant improvement for the user.

Le va et vient de l'ancre 8 libère donc la rotation du tambour 3, notamment du tambour 3 du barillet 10 dans le cas des figures, par son doigt 7, à minuit pour autoriser sa rotation d'un angle d'environ 330°, et à midi de 30° complémentaires.The back and forth of the anchor 8 thus releases the rotation of the drum 3, in particular the drum 3 of the barrel 10 in the case of the figures, by its finger 7, at midnight to allow its rotation by an angle of approximately 330 ° and at noon of 30 ° complementary.

Dans une exécution particulière, le maneton excentrique 42 est assemble sur l'arbre 41 par friction, pour permettre une indexation du saut, par exemple à minuit pour le quantième.In a particular embodiment, the eccentric pin 42 is assembled on the shaft 41 by friction, to allow indexing of the jump, for example at midnight for the date.

La rotation du tambour 3 de 330° entraine le mécanisme d'affichage, notamment de quantième, par la came 5, notamment un colimaçon 51, qui lui est attachée, et qui applique un mouvement au palpeur 6, qui est sur les figures un galet de l'entrainement de quantième, agencé pour mouvoir l'afficheur 100. La suite des fonctions d'affichage, en particulier de quantième, se fait de manière connue, par exemple sous forme de quantième simple ou perpétuel.The rotation of the drum 3 of 330 ° causes the display mechanism, particularly of date, by the cam 5, in particular a spiral 51, which is attached thereto, and which applies a movement to the feeler 6, which is in the figures a pebble of the date training, arranged to move the display 100. The following display functions, in particular date, is done in a known manner, for example in the form of simple or perpetual calendar.

La rotation de 30° complémentaire est perdue, cette rotation est juste nécessaire pour la fonction de l'ancre 8 de déclenchement.The rotation of 30 ° complementary is lost, this rotation is just necessary for the function of the anchor 8 trigger.

Plus particulièrement, avantageusement, le mécanisme 1 est également lié à un mécanisme de régulation 9, ou comporte un mécanisme de régulation 9. Le tambour 3 engrène avec un rouage de ce mécanisme de régulation 9, notamment dans la variante illustrée par les figures, avec un pignon 91 d'une roue de régulation 92, laquelle engrène avec un pignon d'échappement 95, solidaire d'une roue d'échappement de régulation 94. Lors de la rotation du tambour 3, la roue de régulation 92 est entraînée. La roue d'échappement de régulation 94 comporte des dents 95, qui sont agencées pour coopérer avec une ancre de régulation 97, laquelle comporte des palettes 98 et 99. Sous le couple imprimé par le tambour 3, l'ancre de régulation 97 passe alternativement d'une de ses palettes sur l'autre, en entraînant une masse d'inertie 970 qui lui est solidaire. Ce mouvement oscillant de l'ancre de régulation 97 a une fréquence propre qui, sans être aussi isochrone qu'un balancier spiral, permet une bonne régulation d'une fonction. La fréquence de l'oscillateur peut être sensiblement modifiée avec un ressort complémentaire 971, ici monté mobile sur une tête de vis 972, ce qui permet de changer, dans une petite mesure, le temps de fonction.More particularly, advantageously, the mechanism 1 is also connected to a regulation mechanism 9, or comprises a regulation mechanism 9. The drum 3 meshes with a gear of this regulation mechanism 9, in particular in the variant illustrated by the figures, with a pinion 91 of a control wheel 92, which meshes with an escape pinion 95, integral with a control exhaust wheel 94. During the rotation of the drum 3, the control wheel 92 is driven. The control exhaust wheel 94 has teeth 95, which are arranged to cooperate with a control anchor 97, which comprises pallets 98 and 99. Under the torque printed by the drum 3, the control anchor 97 passes alternately of one of its pallets on the other, by driving a mass of inertia 970 which is solidary to him. This oscillating movement of the control anchor 97 has a natural frequency which, without being as isochronous as a balance spring, allows a good regulation of a function. The frequency of the oscillator can be substantially modified with a complementary spring 971, here mounted movably on a screw head 972, which makes it possible to change the function time to a small extent.

D'autres variantes de mécanisme de régulation 9 sont aussi utilisables : régulateur à inertie, à frein centrifuge, à frein magnétique, ou frein à courants de Foucault, ou autres.Other variants of regulation mechanism 9 can also be used: inertia regulator, centrifugal brake, magnetic brake, or eddy current brake, or others.

C'est ce système de régulation qui limite la vitesse du tambour à 1 tour en 2 à 8 secondes environ.It is this control system that limits the drum speed to 1 turn in about 2 to 8 seconds.

Les figures 4 à 7 illustrent la séquence dans l'application décrite ci-dessus.The Figures 4 to 7 illustrate the sequence in the application described above.

La figure 4 illustre l'état du système peu avant midi, vers 11 heures. Le doigt 7 est en coopération d'appui avec la butée 84 de l'ancre 8. Le maneton excentrique 52 est très proche d'une première extrémité 811 de la rainure oblongue 81 de l'ancre 8. Le galet du palpeur 6 est en appui sur le niveau inférieur 511 du colimaçon 51, à proximité immédiate du seuil de remise à zéro 52, dont la position est matérialisée par une radiale en trait mixte. L'entraînement du quantième est donc inactif.The figure 4 illustrates the state of the system shortly before noon, around 11 o'clock. The finger 7 is in bearing cooperation with the abutment 84 of the anchor 8. The eccentric crank pin 52 is very close to a first end 811 of the oblong groove 81 of the anchor 8. The roller of the probe 6 is in support on the lower level 511 of the spiral 51, to immediate proximity of the reset threshold 52, whose position is materialized by a radial dashed line. The training of the date is therefore inactive.

La figure 5 illustre l'état du système peu après midi, vers 12 heures trente. Le doigt 7 est en coopération d'appui avec le bec 83 de l'ancre 8. Le maneton excentrique 52 est encore proche de la première extrémité 811 de la rainure oblongue 81. Le galet du palpeur 6 est en appui sur le niveau inférieur 511 du colimaçon 51, à une distance angulaire α, ici d'environ 30°, du seuil de remise à zéro 52. L'entraînement du quantième est encore inactif.The figure 5 illustrates the state of the system shortly after noon, around 12:30. The finger 7 is in bearing cooperation with the spout 83 of the anchor 8. The eccentric crank pin 52 is still close to the first end 811 of the oblong groove 81. The roller of the probe 6 bears on the lower level 511 of the spiral 51, at an angular distance α, here about 30 °, of the reset threshold 52. The drive of the date is still inactive.

La figure 6 illustre l'état du système peu avant minuit, vers 23 heures. Le doigt 7 est pointe contre pointe avec le bec 83 de l'ancre 8 : le tambour 3 pourra ainsi être libéré, pour sa rotation de presque un tour, dès que ce contact ponctuel sera rompu. Le maneton excentrique 52 a traversé dans l'après-midi la rainure oblongue 81 de l'ancre 8, et est maintenant très proche d'une deuxième extrémité 812 de cette rainure oblongue 81. Le galet du palpeur 6 est encore en appui sur le niveau inférieur 511 du colimaçon 51, à proximité immédiate du seuil de remise à zéro 52. L'entraînement du quantième est toujours inactif.The figure 6 illustrates the state of the system shortly before midnight, around 23 hours. The finger 7 is tip against tip with the nozzle 83 of the anchor 8: the drum 3 can be released, for its rotation of almost a turn, as soon as this point contact is broken. The eccentric pin 52 has traversed in the afternoon the oblong groove 81 of the anchor 8, and is now very close to a second end 812 of this oblong groove 81. The roller of the feeler 6 is still resting on the lower level 511 of the spiral 51, in the immediate vicinity of the reset threshold 52. The training of the date is always inactive.

Peu après, au voisinage de minuit, le doigt 7 quitte le bec 83 de l'ancre 8, le tambour 3 effectue sa rotation d'un angle β, ici d'environ 330°. Pendant cette rotation qui est régulée par le mécanisme de régulation 9, détaillé sur la figure 1, afin de durer quelques secondes et être bien visible pour l'utilisateur, le galet du palpeur 6 parcourt d'abord le niveau inférieur 511 du colimaçon 51, puis monte sur le niveau supérieur 512, activant l'entraînement du quantième pour l'affichage de la nouvelle date. Le galet 6 chute lors du passage du seuil de remise à zéro 52.Shortly after, in the vicinity of midnight, the finger 7 leaves the spout 83 of the anchor 8, the drum 3 rotates at an angle β, here about 330 °. During this rotation which is regulated by the regulation mechanism 9, detailed on the figure 1 in order to last a few seconds and be clearly visible to the user, the feeler roller 6 first travels the lower level 511 of the spiral 51 and then climbs to the upper level 512, activating the date drive for the display of the new date. The roller 6 drops when the reset threshold 52 passes.

La figure 7 illustre l'état du système peu après minuit, vers 0 heures trente. Le doigt 7 est à nouveau en coopération d'appui avec la butée 84 de l'ancre 8. Le maneton excentrique 52 est encore proche de la deuxième extrémité 812 de la rainure oblongue 81. Le galet du palpeur 6 est retombé, depuis sa position haute illustrée en trait mixte, dans sa position basse en appui sur le niveau inférieur 511 du colimaçon 51. L'angle β parcouru est celui formé entre les positions du seuil de remise à zéro 52 sur les figures 6 et 7.The figure 7 illustrates the state of the system shortly after midnight, around half past twelve. The finger 7 is again in support cooperation with the abutment 84 of the anchor 8. The eccentric crankpin 52 is still close to the second end 812 of the oblong groove 81. The roller of the probe 6 has fallen from its position high shown in phantom, in its low position resting on the lower level 511 of the spiral 51. The angle β traveled is that formed between the positions of the reset threshold 52 on the Figures 6 and 7 .

L'invention concerne encore un mouvement 500 d'horlogerie comportant un tel mécanisme d'affichage 1.The invention also relates to a watch movement 500 comprising such a display mechanism 1.

L'invention concerne encore une pièce d'horlogerie, notamment une horloge, ou une montre 1000, comportant un tel mouvement 500 ou/et un tel mécanisme d'affichage 1.The invention also relates to a timepiece, in particular a clock, or a watch 1000, comprising such a movement 500 and / or such a display mechanism 1.

Des variantes de l'invention sont possibles.Variants of the invention are possible.

Le déclenchement à minuit peut être fait par d'autres principes, par exemple avec un pignon poussé (type force constante). Par exemple, le troisième mobile 80 est une étoile ou un pignon solidaire d'un arbre 41 du premier mobile 4.The triggering at midnight can be done by other principles, for example with a pushed gear (constant force type). For example, the third mobile 80 is a star or a pinion integral with a shaft 41 of the first mobile 4.

Une autre variante constitue la configuration inverse de celle illustrée par les figures : le deuxième mobile 30 est un barillet 3 agencé pour être entraîné par un mobile d'entraînement 201, et qui est porteur du troisième mobile 80. Et le premier mobile 4 est alors agencé pour entraîner ou porter ladite came 5 périphérique en colimaçon 51.Another variant constitutes the configuration opposite to that illustrated by the figures: the second mobile 30 is a cylinder 3 arranged to be driven by a drive wheel 201, and which carries the third mobile 80. And the first mobile 4 is then arranged to drive or carry said peripheral spiral cam 51.

La régulation peut être assurée par d'autre type de régulateur, de type de régulateur de sonnerie, par exemple régulateur à courants de Foucault, ou régulateur magnétique, ou régulateur électrostatique, ou autre.The regulation can be provided by other type of regulator, type of ring regulator, for example eddy current regulator, or magnetic regulator, or electrostatic regulator, or other.

Le temps de la fonction, qui est défini par le type de mécanisme de régulation 9 choisi, peut être choisi librement, ici il est, non limitativement défini entre 1 et 30 secondes. En effet, à ces vitesses, les contraintes dynamiques engendrées par la vitesse sont négligeables, seules les contraintes statiques sont sensibles.The time of the function, which is defined by the type of control mechanism 9 chosen, can be chosen freely, here it is not limited to between 1 and 30 seconds. Indeed, at these speeds, the dynamic stresses generated by the speed are negligible, only the static stresses are sensitive.

Le saut de quantième se fait de manière à ne générer que des contraintes pouvant être calculées en statique, l'effet dynamique lié aux inerties des composants pendant le saut est négligeable.The date jump is made so as to generate only constraints that can be computed statically, the dynamic effect related to inertia components during the jump is negligible.

Le saut se fait de manière jugée instantanée à l'échelle d'une journée, mais en restant bien visible par l'utilisateur, ce qui donne un rendu qualitatif.The jump is judged instantaneous at the scale of a day, but remains visible to the user, which gives a qualitative result.

Le saut étant limité à quelques secondes, les limitations temporelles pour les corrections de quantième sont limitées, de même les risques de perte d'informations et les défauts de fonctionnement sont limités.Since the jump is limited to a few seconds, the time limitations for date corrections are limited, and the risks of information loss and malfunctions are limited.
