- Positionner la came des mois dans une deuxième position définissant un deuxième état du système de calendrier dans lequel, alors que le mobile des quantièmes est en position pour indiquer le quantième « 30 », une action de l'élément d'entraînement du système de calendrier provoque une avancée d'un pas du mobile des quantièmes.
- Position the cam of the months in a first position defining a first state of the calendar system in which, while the calendar mobile is in position to indicate the date "30", an action of a training element of the calendar system causes an advance of two steps of the mobile calendar; and
- Position the cam of the months in a second position defining a second state of the calendar system in which, while the calendar mobile is in position to indicate the date "30", an action of the training element of the calendar system causes a step forward of the mobile dates.
Sauf incompatibilité logique ou technique, toute combinaison de caractéristiques du premier aspect de l'invention est combinable avec toute combinaison de caractéristiques du deuxième aspect.Unless logical or technical incompatibility, any combination of features of the first aspect of the invention is combinable with any combination of features of the second aspect.
De préférence, l'invention concerne un système de calendrier dont le dispositif d'affichage de l'indication des mois est doté d'un organe d'affichage de l'indication des mois qui présente la spécificité de n'être visible du porteur que de manière ponctuelle, par exemple lors de l'affichage d'un quantième particulier, notamment pour les phases de réglage du système de calendrier.Preferably, the invention relates to a calendar system whose month indication display device is provided with a display member of the month indication which has the specificity of being visible to the wearer only. in a specific manner, for example during the display of a particular calendar, in particular for the adjustment phases of the calendar system.
Le système de calendrier présente notamment la particularité d'entraîner, au moins partiellement, l'organe d'affichage de l'indication des mois entre le premier et le trente et unième quantième d'un mois en cours.The calendar system has the particular feature of driving, at least partially, the display member of the month indication between the first and the thirty-first calendar of a current month.
Un tel système propose une alternative avantageuse aux dispositifs d'affichage permanent de l'indication des mois qui peuvent surcharger le cadran d'une pièce d'horlogerie. Un tel système permet par ailleurs de simplifier la construction d'un mouvement du type quantième annuel ou quantième perpétuel. Dans un mode de réalisation particulier, le système permet également de minimiser et de répartir l'énergie requise à l'entraînement de l'organe d'affichage de l'indication des mois ou d'une came des mois.Such a system offers an advantageous alternative to permanent display devices indicating the months that can overload the dial of a timepiece. Such a system also makes it possible to simplify the construction of a movement of the annual calendar or perpetual calendar type. In a particular embodiment, the system also makes it possible to minimize and distribute the energy required to drive the display member of the indication of the months or a cam of the months.
De préférence donc, dans le système de calendrier, l'organe d'affichage des mois est visible uniquement dans une configuration prédéterminée de l'organe d'affichage des quantièmes, par exemple le premier d'un mois donné, et/ou l'organe d'affichage des mois est entraîné, au moins partiellement, entre le premier et le trente et unième quantième d'un mois en cours.Preferably therefore, in the calendar system, the month display member is visible only in a predetermined configuration of the date display member, for example the first of a given month, and / or the month display organ is trained, at least partially, between the first and the thirty-first calendar of a current month.
Un tel affichage ponctuel de l'indication des mois a en effet pour avantage de permettre une désynchronisation au moins partielle du mobile d'affichage des mois vis-à-vis du mobile d'affichage des quantièmes, ce qui peut simplifier et/ou optimiser la construction d'un système de calendrier à quantième annuel ou perpétuel dans lequel le mobile des mois est lié cinématiquement au mobile des quantièmes, en particulier dans lequel le mobile des mois est uniquement lié cinématiquement au mobile des quantièmes. Un tel système de calendrier permet notamment de proposer une structure du mobile des quantièmes particulièrement simple dans laquelle le mobile est doté uniquement de deux jeux de denture distincts.Such a punctual display of the indication of the months has indeed the advantage of allowing at least partial desynchronization of the month display mobile vis-à-vis the date display mobile, which can simplify and / or optimize the construction of an annual or perpetual calendar calendar system in which the motive of the months is kinematically linked to the mobile of the calendars, in particular in which the motive of the months is only kinematically linked to the mobile of the calendars. Such a calendar system makes it possible in particular to propose a particularly simple structure of the date mobile in which the mobile is provided with only two sets of distinct toothing.
Les dessins annexés représentent, à titre d'exemples, deux modes de réalisation de systèmes de calendriers horlogers selon l'invention.The appended drawings represent, by way of example, two embodiments of watch calendar systems according to the invention.

Le système 100 de calendrier horloger comprend :
un organe d'affichage 10 des quantièmes comprenant une ouverture 10a ; etun organe d'affichage 30 des mois agencé de sorte à afficher une indication de mois dans l'ouverture 10a, notamment lorsque l'ouverture 10a est visible par un utilisateur du système de calendrier et/ou lorsque le système de calendrier indique le premier quantième d'un mois donné.
- a
date display member 10 comprising anopening 10a; and - a
display member 30 months arranged to display a month indication in theopening 10a, especially when theopening 10a is visible by a user of the calendar system and / or when the calendar system indicates the first calendar of a given month.
De préférence, l'ouverture 10a est un premier guichet en vis-à-vis d'une indication de quantième ou juxtaposée à une indication de quantième, en particulier en vis-à-vis du quantième « 1 » ou juxtaposée au quantième « 1 ». Dans le premier mode de réalisation décrit, l'ouverture 10a est donc juxtaposée à l'indication du premier quantième. Il est bien entendu possible de disposer l'ouverture 10a en regard d'un autre quantième.Preferably, the
De préférence encore, l'organe d'affichage 30 des mois ou organe indicateur des mois est agencé de sorte à afficher une indication de mois dans l'ouverture 10a lorsque le système de calendrier indique le premier quantième d'un mois donné.More preferably, the month display member or month indicator member is arranged to display a month indication in the
Dans le premier mode de réalisation, le mobile d'affichage des mois est actionné sur un seul et unique pas angulaire du disque des quantièmes effectué entre le premier et le trente et unième quantième d'un mois en cours.In the first embodiment, the month display mobile is operated on a single single angular step of the date disk made between the first and the thirty-first calendar of a current month.
Le premier mode de réalisation présente la particularité d'être doté d'un mobile 1 des quantièmes qui comporte une première denture extérieure 1a prévue pour coopérer avec une denture 2a d'un ensemble 2 de programmation. Le mobile 1 des quantièmes présente une denture 1 b qui se réduit à une dent 1 b prévue pour coopérer à la fois avec une denture 2b de l'ensemble de programmation 2 comme représenté sur la
L'organe 10 d'affichage des quantièmes ou organe indicateur des quantièmes est disposé au dessus de l'organe 30 indicateur des mois. Ainsi, l'indication des mois n'est pas visible de l'utilisateur à travers une glace de la pièce d'horlogerie et notamment à travers un second guichet 4 réalisé par exemple dans un cadran 99 (représenté partiellement sur la
Durant les phases d'immobilisation des mobiles 1 et 3, ces derniers sont indexés classiquement par le biais de sautoirs 5, 6, dont les becs 5a, 6a sont respectivement prévus pour coopérer avec les dentures 1a et 3a comme représenté sur la
L'ensemble 2 est agencé de sorte que le système de calendrier distingue les mois courts des mois longs. A cet effet, les dentures 2a, 2b de l'ensemble 2 sont toutes deux prévues pour être actionnées, tous les jours, par un élément 7 d'entraînement du système de calendrier doté de deux doigts d'entraînement 7a, 7b qui sont chacun dédiés à l'entraînement des dentures 2a, 2b. Le doigt 7b actionne la denture 2b par l'intermédiaire d'une denture 2c, ces deux dentures 2b et 2c étant solidaires en rotation grâce à une goupille 200 comme représenté sur la
L'interaction entre une dent de la denture 2a de l'ensemble 2 et une dent de la denture 1a du mobile 1 se produit lors de chaque changement de quantième. Par contre, l'interaction entre une dent de la denture 2b de l'ensemble 2 et la dent 1 b du mobile 1 ne se produit qu'à la fin de chaque mois court, plus particulièrement lors de la transition d'affichage du trentième au « trente et unième » quantième de chaque mois court. A titre d'exemple, les
Durant ces phases de changement de date en fin de mois, on remarque que le mobile 3 des mois, en particulier l'organe 30 d'affichage des mois, reste immobile. On remarque que dans la séquence de fonctionnement illustrée par les
L'actionnement du mobile 3 des mois est effectué en cours de mois lorsque la dent 1b vient agir sur la denture 3a, plus particulièrement lors du passage du onzième au douzième quantième d'un mois en cours comme illustré sur les
De préférence encore, l'élément d'entraînement de l'organe d'affichage des mois est agencé pour entraîner d'un pas l'organe d'affichage des mois alors que l'organe d'affichage des quantièmes est entraîné d'un pas.More preferably, the drive member of the month display member is arranged to step one step the month display member while the date display member is driven by a not.
L'élément d'entraînement est avantageusement le mobile des quantièmes. Il comprend au moins une dent 1 b coopérant avec plusieurs dents 3a du mobile 3 des mois, en particulier une dent 1 b coopérant avec douze dents 3a du mobile 3 des mois.The driving element is advantageously the mobile dates. It comprises at least one
Un tel mode de réalisation permet la mise en oeuvre d'un mobile des quantièmes simplifié, doté uniquement de deux niveaux distincts pour l'agencement des dentures 1a, 1b. Il en découle également une conception plus compacte, avec une épaisseur de module de calendrier minimisée. Alternativement, la denture 1b pourrait être agencée sur un même niveau que la denture 1a par le biais d'une géométrie de denture 1 b se distinguant de celle de la denture 1 a.Such an embodiment allows the implementation of a simplified date mobile, with only two distinct levels for the arrangement of
Un deuxième mode de réalisation d'une pièce d'horlogerie 220 est décrit ci-après en référence aux

Le mouvement horloger comprend un deuxième mode de réalisation d'un système de calendrier 200 selon l'invention. Avantageusement, le système de calendrier est du type à quantième annuel, voire à quantième perpétuel.The watch movement comprises a second embodiment of a
Le système 200 de calendrier horloger comprend :
un organe d'affichage 10 des quantièmes comprenant une ouverture 10a ; etun organe d'affichage 30 des mois agencé de sorte à afficher une indication de mois dansl'ouverture 10a.
- a
date display member 10 comprising anopening 10a; and - a month display member arranged to display a month indication in the
aperture 10a.
Les éléments des premier et deuxième modes de réalisation du système de calendrier ayant la même structure ou la même fonction sont référencés par les mêmes signes numériques.The elements of the first and second embodiments of the calendar system having the same structure or the same function are referenced by the same numerical signs.
Le premier aspect de l'invention est aussi illustré par le deuxième mode de réalisation décrit ci-après. Ce deuxième mode de réalisation se distingue principalement du premier mode de réalisation décrit plus haut en ce que :
- le mobile des mois est entraîné d'un pas sur plusieurs pas d'entraînement du mobile des quantièmes ; et/ou
- l'organe d'affichage des quantièmes et l'organe d'affichage des mois sont pivotés autour d'un même axe P, soit de manière coaxiale, et/ou le mobile des quantièmes et le mobile des mois sont pivotés autour d'un même axe P, soit de manière coaxiale.
- the motive of the months is driven by a step on several steps of the mobile of the dates; and or
- the date display member and the month display member are rotated about the same axis P, or coaxially, and / or the mobile dates and month mobile are rotated around a same axis P, coaxially.
Dans le deuxième mode de réalisation, le mobile d'affichage des mois est ainsi actionné sur plusieurs pas angulaires du disque des quantièmes comme représenté sur les
Le mobile 1 des quantièmes présente une denture intérieure 1a prévue pour être actionnée par un doigt 7a entraîneur des quantièmes. Dans le mode de réalisation représenté, le mobile des quantième comprend en outre une denture 1b disposée à la périphérie extérieure du mobile 1 et qui est prévue pour coopérer avec une denture 3a du mobile 3 des mois par le biais de l'élément de liaison cinématique 8. L'élément de liaison est pivoté autour d'un axe parallèle à l'axe P.The mobile 1 of the dates has an
L'élément de liaison 8 peut par exemple comprendre une croix de Malte 8 comme représenté sur les
En fonctionnement conventionnel du système de calendrier, la position angulaire du mobile 1 est indexée par le biais d'un sautoir 5 dont la tête 5a est prévue pour coopérer avec la denture 1a. La position angulaire du mobile 3 est, quant à elle, garantie, aux jeux de dentures près, par une périphérie circulaire extérieure 1c du mobile 1, qui est prévue pour coopérer avec un profil polygonal ou sensiblement polygonal 8c de l'élément de liaison 8. L'actionnement du mobile des mois est opéré par l'engrènement de la denture 1b avec une denture 8a de l'élément de liaison 8, ainsi que par l'engrènement de la denture 8b avec la denture 3a. En conséquence, lors de certains pas du mobile des quantièmes, le mobile des mois est entraîné de 1/n pas au plus et lors d'autres pas du mobile des quantièmes, le mobile des mois n'est pas entraîné.In conventional operation of the calendar system, the angular position of the mobile 1 is indexed by means of a
Dans le mode de réalisation représenté, le mobile des quantièmes présente quatre dents 1 b. Un saut de quantième entraîne le mobile 3 des mois sur un quart de son pas angulaire, quand une dent 1 b interagit avec l'élément de liaison. Toutefois, un saut de quantième n'entraîne pas le mobile 3 des mois, quand aucune dent 1b n'interagit avec l'élément de liaison. Autrement dit, le mobile des mois est actionné sur quatre pas angulaires du disque des quantièmes. Par exemple, ces actionnements ou entraînements ont lieu lors des passages du deuxième au troisième quantième, du dixième au onzième quantième, du dix-septième au dix-huitième quantième et du vingt-cinquième au vingt-sixième quantième, qui sont affichés dans le guichet 4 du cadran 99 (représenté partiellement sur la
Ainsi, dans ce deuxième mode de réalisation, l'énergie nécessaire au passage du mois peut être répartie sur plusieurs sauts de quantièmes instantanés, et ce, sans sautoir additionnel. L'énergie consacrée au changement de l'indication du mois est donc très faible et n'a pas d'influence négative sur la précision de la montre.Thus, in this second embodiment, the energy required for the passage of the month can be distributed over several jumps instantaneous dates, and without additional jumper. The energy devoted to changing the indication of the month is therefore very small and has no negative influence on the precision of the watch.
Comme dans le premier mode de réalisation, l'indication des mois n'est de préférence pas visible à travers le guichet 4, tant que l'ouverture 10a formée sur l'organe 10 n'est pas disposée dans le guichet 4. Dans le deuxième mode de réalisation, l'ouverture 10a est juxtaposée à l'indication du premier quantième « 1 » comme représenté sur les
La construction illustrée par les
Dans les différents modes de réalisation, le mobile 3 des mois peut être solidaire d'une came des mois ou came de programmation 300 de calendrier annuel ou perpétuel comme illustré sur les
Ainsi, l'organe d'affichage 30 des mois et la came 300 de programmation de calendrier peuvent être entraînés simultanément ou ensemble.Thus, the
A titre d'exemple, la

Ainsi, la came des mois est agencée de sorte à définir :
- un premier état du système de calendrier dans lequel, alors que le mobile des quantièmes est en position pour indiquer le quantième « 30 », une action de l'élément d'entraînement 7 du système de calendrier provoque une avancée de deux pas du mobile des quantièmes ; et
- un deuxième état du système de calendrier dans lequel, alors que le mobile des quantièmes est en position pour indiquer le quantième « 30 », une action de l'élément d'entraînement 7 du système de calendrier provoque une avancée d'un pas du mobile des quantièmes.
- a first state of the calendar system in which, while the calendar mobile is in position to indicate the date "30", an action of the
drive element 7 of the calendar system causes a two-step advance of the mobile of the dates; and - a second state of the calendar system in which, while the calendar mobile is in position to indicate the date "30", an action of the
training element 7 of the calendar system causes a step forward of the mobile dates.
Autrement dit, l'invention porte également sur un procédé de fonctionnement d'un système de calendrier horloger ou d'un mouvement horloger ou d'une pièce d'horlogerie dans lequel le procédé comprend les étapes suivantes :
- Positionner la came des mois dans une première position définissant un premier état du système de calendrier dans lequel, alors que le mobile des quantièmes est en position pour indiquer le quantième « 30 », une action de l'élément d'entraînement 7 du système de calendrier provoque une avancée de deux pas du mobile des quantièmes ; et
- Positionner la came des mois dans une deuxième position définissant un deuxième état du système de calendrier dans lequel, alors que le mobile des quantièmes est en position pour indiquer le quantième « 30 », une action de l'élément d'entraînement 7 du système de calendrier provoque une avancée d'un pas du mobile des quantièmes.
- Positioning the cam of the months in a first position defining a first state of the calendar system in which, while the calendar mobile is in position to indicate the date "30", an action of the
drive element 7 of the system of calendar causes an advance of two steps of the mobile calendar; and - Position the cam of the months in a second position defining a second state of the calendar system in which, while the date mobile is in position to indicate the date "30", an action of the
drive element 7 of the system of calendar causes a step forward of mobile dates.
Selon le deuxième aspect de l'invention illustré par le deuxième mode de réalisation du système de calendrier, le système 200 de calendrier horloger comprend de préférence :
- le mobile 1 des quantièmes ;
- la came des
mois 300 ; et l'élément 8 de liaison cinématique agencé de sorte que le mobile des quantièmes permette l'entraînement en mouvement de la came des mois.
- the mobile 1 of the dates;
- the cam of the
month 300; and - the kinematic connecting
element 8 arranged so that the date mobile allows the drive in motion of the cam months.
Préférentiellement, l'entraînement en mouvement de la came des mois est exclusivement opéré par le mobile 1 des quantièmes. Plus particulièrement, l'entraînement en mouvement de la came des mois est de préférence exclusivement opéré par le mobile 1 des quantièmes par l'intermédiaire de l'élément 8 de liaison cinématique.Preferably, the movement drive of the cam of the months is exclusively operated by the mobile 1 of the dates. More particularly, the movement drive of the cam of the months is preferably exclusively operated by the mobile 1 of the dates by means of the kinematic connecting
Comme vu précédemment, le mobile des quantièmes peut comprendre l'organe d'affichage ou d'indication des quantièmes, en particulier le disque d'affichage des quantièmes.As seen above, the calendar mobile may include the date display or indication member, in particular the date display disc.
De même, le mobile des mois peut comprendre l'organe d'affichage ou d'indication des mois, en particulier le disque d'affichage des mois.Similarly, the mobile months may include the display member or indication of the months, in particular the display disc months.
L'élément de liaison cinématique est de préférence agencé pour permettre l'entraînement, notamment l'entraînement exclusif, de la came des mois d'un pas, en particulier d'un douzième de tour, au cours d'un mois. En particulier, l'élément de liaison cinématique peut être agencé pour permettre l'entraînement de la came des mois d'au plus 1/n pas alors que le mobile des quantièmes est entraîné d'un pas, avec n un entier naturel supérieur à 1, notamment n=2 ou n=3 ou n=4 ou n=5.The kinematic connecting element is preferably arranged to allow the drive, in particular the exclusive drive, of the cam months of a step, especially a twelfth of a turn, in a month. In particular, the kinematic connecting element can be arranged to allow the drive of the cam of the months of not more than 1 / n not while the mobile dates are driven one step, with n a natural integer greater than 1, in particular n = 2 or n = 3 or n = 4 or n = 5.
Comme vu précédemment, l'élément de liaison cinématique peut comprendre un dispositif de renvois coopérant par engrenage avec la came des mois et coopérant par engrenage avec le mobile des quantièmes.As seen above, the kinematic linkage element may comprise a gear-engaging device cooperating with the cam of the months and co-operating by gearing with the mobile of the dates.
Dans les différents modes de réalisation, le mobile des quantièmes et l'organe d'affichage ou d'indication des quantièmes peuvent former un ensemble monobloc ou venir d'une même pièce. Alternativement, l'organe et le mobile peuvent être rapportés l'un sur l'autre. De même, le mobile des mois et l'organe d'affichage ou d'indication des mois peuvent former un ensemble monobloc ou venir d'une même pièce. Alternativement, l'organe et le mobile peuvent être rapportés l'un sur l'autre.In the various embodiments, the mobile dates and the date display or indication member may form a one-piece assembly or come from the same room. Alternatively, the organ and the mobile can be reported on one another. Similarly, the mobile months and the display member or indication of the months may form a one-piece assembly or come from the same room. Alternatively, the organ and the mobile can be reported on one another.
Dans les différents modes de réalisation, l'ouverture 10a formée sur cet organe 10 peut bien entendu consister en une zone transparente du même organe, notamment une première zone transparente intégrée au sein d'une deuxième zone plus étendue translucide ou opaque. Pour une pièce d'horlogerie dénuée de cadran, notamment une pièce d'horlogerie de type « squelette », l'ouverture 10a se suffit à elle-même pour rendre visible l'indication du mois.In the different embodiments, the
Dans les différents modes de réalisation, l'indication du premier quantième « 1 », ou de tout autre quantième prévu pour être affiché avec l'indication du mois, peut, par ailleurs, être portée par l'organe 30 d'affichage des mois.In the different embodiments, the indication of the first date "1", or of any other date scheduled to be displayed with the indication of the month may, moreover, be carried by the
Préférentiellement, un système de calendrier selon l'invention est accompagné d'un système de correction rapide. Un tel système de calendrier peut également être doté d'un mécanisme laissant apparaître l'ouverture 10a uniquement en mode de réglage du système de calendrier, par exemple en fonction de la position axiale de la tige de réglage du mouvement horloger.Preferably, a calendar system according to the invention is accompanied by a fast correction system. Such a calendar system may also be provided with a mechanism showing the
Dans les différents modes de réalisation, le système de calendrier horloger est de préférence du type à saut instantané.In the various embodiments, the watch calendar system is preferably of the instant jump type.
