Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne un système de positionnement pour un mécanisme d'affichage de quantième grande date. La présente invention concerne également une pièce d'horlogerie comprenant un tel système de positionnement.The present invention relates to a positioning system for a large date display mechanism. The present invention also relates to a timepiece comprising such a positioning system.

Arrière-plan technologique de l'inventionTechnological background of the invention

La présente invention s'intéresse aux mécanismes d'affichage de quantième dits « grande date » prévus pour équiper des pièces d'horlogerie mécaniques ou électromécaniques. Ces mécanismes d'affichage de quantième grande date sont appelés ainsi car ils permettent d'afficher l'indication de date à plus grande échelle, ce qui facilite la lecture de la date et apporte un plus indéniable à l'esthétique de la pièce d'horlogerie équipée d'un tel mécanisme.The present invention is concerned with the so-called “big date” date display mechanisms provided to equip mechanical or electromechanical timepieces. These large date display mechanisms are so called because they allow the date indication to be displayed on a larger scale, which facilitates the reading of the date and brings an undeniable plus to the aesthetics of the watch. clockwork equipped with such a mechanism.

Un mécanisme d'affichage de date classique comprend essentiellement un anneau de quantième sur le pourtour duquel sont reportées les indications de date de « 1 » à « 31 ». Cet anneau de quantième avance d'un pas par jour. A la fin des mois de moins de 31 jours, le propriétaire de la montre doit faire avancer l'anneau de quantième de l'indication de date « 28 » ou de l'indication de date « 29 » en cas d'année bissextile jusqu'à l'indication de date « 1 » lorsqu'il est au mois de février, et de l'indication de date « 30 » jusqu'à l'indication de date « 1 » pour les autres mois de l'année ayant moins de 31 jours.A conventional date display mechanism essentially comprises a date ring on the periphery of which the date indications from "1" to "31" are shown. This date ring moves forward one step per day. At the end of the months of less than 31 days, the owner of the watch must advance the date ring of the date indication "28" or of the date indication "29" in the case of a leap year to 'to the date indication "1" when it is in the month of February, and from the date indication "30" to the date indication "1" for the other months of the year having less 31 days.

Les mécanismes d'affichage de date qui nécessitent une intervention du propriétaire à la fin de chaque mois de moins de 31 jours sont appelés mécanismes d'affichage de date simples. Les mécanismes d'affichage de date qui ne nécessitent une intervention du propriétaire qu'une fois par an, lors du passage du mois de février au mois de mars, sont appelés mécanismes d'affichage de date semi-perpétuels. Enfin, les mécanismes d'affichage de date qui passent spontanément de l'indication de date du dernier jour d'un mois de moins de 31 jours à l'indication de date du premier jour du mois suivant, et ce y compris les années bissextiles, sont appelés mécanismes d'affichage de date perpétuels.Date display mechanisms that require owner intervention at the end of each month less than 31 days old are called simple date display mechanisms. The display mechanisms of date that only requires owner intervention once a year, when the month of February changes to March, are called semi-perpetual date display mechanisms. Finally, the date display mechanisms which spontaneously switch from the date indication of the last day of a month of less than 31 days to the date indication of the first day of the following month, and this including leap years , are called perpetual date display mechanisms.

Les mécanismes d'affichage de date qui comprennent un unique anneau sur le pourtour duquel sont réparties les indications de quantième de « 1 » à « 31 » ont pour avantage de comprendre un nombre limité de pièces. Ils sont donc plus économiques et plus faciles à intégrer dans un mouvement d'horlogerie d'une montre mécanique ou électromécanique. Par contre, on ne dispose que d'un secteur angulaire d'un peu moins de 12° pour reproduire chacune des 31 indications de date sur l'anneau de quantième. La taille des indications de date est donc nécessairement limitée par les dimensions de l'anneau de quantième, ce qui peut rendre ces indications de date difficiles à lire.The date display mechanisms which include a single ring around which the date indications are distributed from “1” to “31” have the advantage of comprising a limited number of parts. They are therefore more economical and easier to integrate into a clockwork movement of a mechanical or electromechanical watch. On the other hand, we only have an angular sector of a little less than 12 ° to reproduce each of the 31 date indications on the date ring. The size of the date indications is therefore necessarily limited by the dimensions of the date ring, which can make these date indications difficult to read.

Les mécanismes d'affichage de quantième grande date comprennent classiquement un premier indicateur de quantième sur lequel sont reportées les indications des unités de quantième de « 0 » à « 9 ». Ces 10 chiffres sont reproduits sur le premier indicateur de quantième selon des enchaînements qui dépendent du mode de fonctionnement du mécanisme d'affichage grande date considéré. Ces mécanismes d'affichage de quantième sont complétés par un second indicateur de quantième sur lequel sont reproduites les indications des dizaines de quantième de « 0 » à « 3 ». Ainsi, en ajustant convenablement la position du premier indicateur de quantième par rapport au second indicateur de quantième, il est possible de constituer toutes les indications de quantième de « 01 » à « 31 » en combinant les indications des unités de quantième portées par le premier indicateur de quantième avec les indications des dizaines de quantième portées par le second indicateur de quantième. Comme le premier indicateur de quantième ne porte que les indications des unités de quantième et le second indicateur de quantième que les indications des dizaines de quantième, on dispose de davantage de place pour reproduire ces indications qui peuvent donc être de plus grande taille. La lecture d'un dispositif indicateur de quantième grande date est donc plus aisée et l'esthétique d'une pièce d'horlogerie équipée d'un tel dispositif indicateur de quantième est grandement améliorée. Un tel mécanisme est connu du document WO2007/065889A2 .Large date date display mechanisms conventionally include a first date indicator on which the indications of the date units from “0” to “9” are shown. These 10 digits are reproduced on the first date indicator in sequences which depend on the operating mode of the large date display mechanism in question. These date display mechanisms are supplemented by a second date indicator on which the indications of the tens of date from “0” to “3” are reproduced. Thus, by suitably adjusting the position of the first date indicator relative to the second date indicator, it is possible to constitute all the date indications from "01" to "31" by combining the indications of the date units carried by the first. date indicator with the tens of date indications carried by the second date indicator. Like the first date indicator only carries the indications of the date units and the second date indicator only the indications of the tens of the date, more room is available to reproduce these indications which can therefore be of larger size. Reading a large date date indicator device is therefore easier and the aesthetics of a timepiece equipped with such a date indicator device is greatly improved. Such a mechanism is known from the document WO2007 / 065889A2 .

Un problème se pose cependant lors du passage du « 31 » d'un mois donné au « 01 » du mois suivant. En effet, par construction, l'indication de l'unité de quantième « 1 » avec laquelle est composée l'indication de quantième « 31 » est la même que l'indication de l'unité de quantième « 1 » avec laquelle est composée l'indication de quantième « 01 ». Par conséquent, durant le passage de l'indication de quantième « 31 » à l'indication de quantième « 01 », l'indication de l'unité de quantième « 1 » reste inchangée, tandis que l'indication de dizaine du quantième passe de la valeur « 3 » à la valeur « 0 ». Autrement dit, lors du passage de la fin d'un mois de 31 jours au premier jour du mois suivant, le premier indicateur de quantième sur lequel sont reportées les indications des unités de quantième doit rester immobile. Pour atteindre cet objectif, il convient d'empêcher le mouvement d'horlogerie qui, en temps normal, assure l'avance quotidienne du mécanisme d'affichage grande date, d'entraîner le premier indicateur de quantième lors du passage du dernier jour d'un mois de 31 jours au 1er jour du mois suivant.However, a problem arises when changing from “31” of a given month to “01” of the following month. In fact, by construction, the indication of the date unit "1" with which the date indication "31" is composed is the same as the indication of the date unit "1" with which the date unit is composed. the date indication "01". Consequently, during the passage from the date indication "31" to the date indication "01", the indication of the date unit "1" remains unchanged, while the ten indication of the date passes. from value "3" to value "0". In other words, when passing from the end of a 31-day month to the first day of the following month, the first date indicator on which the indications of the date units are shown must remain stationary. To achieve this objective, it is necessary to prevent the clockwork movement which, in normal times, ensures the daily advance of the large date display mechanism, from driving the first date indicator during the passage of the last day of a month of 31 days on the 1st day of the following month.

La solution habituellement proposée pour résoudre ce problème consiste à priver l'une des roues qui se trouve dans la chaîne cinématique comprise entre la sortie du mouvement d'horlogerie et l'indicateur de quantième qui porte les indications des unités de quantième d'au moins une dent de façon que, bien qu'entraînée par le mouvement d'horlogerie, cette roue ne parvienne pas à entraîner à son tour le pignon avec lequel elle est en prise lors du passage du « 31 » au « 01 ». Le pignon restant immobile durant cette période, la liaison cinématique entre le mouvement d'horlogerie et le premier indicateur de quantième qui porte les indications des unités de quantième est interrompue, et l'indication des unités de quantième « 1 » reste inchangée.The solution usually proposed to solve this problem consists in depriving one of the wheels which is located in the kinematic chain between the output of the clockwork movement and the date indicator which bears the indications of the date units of at least a tooth so that, although driven by the clockwork movement, this wheel in turn does not manage to drive the pinion with which it is engaged when going from "31" to "01". As the pinion remains stationary during this period, the kinematic connection between the watch movement and the first date indicator which carries the indications of the date units is interrupted, and the indication of the date units "1" remains unchanged.

Cette solution pose cependant un problème, à savoir que durant le passage du dernier jour d'un mois de 31 jours au premier jour du mois suivant au cours duquel le pignon n'est plus en prise avec la roue qui le restant du temps assure son entraînement, le maintien en position du pignon, et donc du premier indicateur de quantième qui porte les indications des unités de quantième, n'est plus assuré, ce qui n'est pas acceptable car on ne peut garantir le positionnement convenable de l'indication des unités du quantième dans un guichet ménagé dans un cadran de la pièce d'horlogerie et à travers lequel l'indication de quantième est visible.However, this solution poses a problem, namely that during the passage from the last day of a month of 31 days to the first day of the following month during which the pinion is no longer in engagement with the wheel which the rest of the time ensures its drive, the maintenance in position of the pinion, and therefore of the first date indicator which bears the indications of the date units, is no longer ensured, which is not acceptable because the correct positioning of the indication cannot be guaranteed date units in a window provided in a dial of the timepiece and through which the date indication is visible.

La présente invention a pour but de résoudre le problème exposé ci-dessus en procurant un mécanisme d'affichage de quantième grande date dans lequel l'indexation d'un pignon situé dans la chaîne cinématique qui réalise l'entraînement d'un anneau indicateur des unités est assurée, même lorsque ce pignon n'est pas en prise avec une roue entraîneuse avec laquelle il engrène en temps normal afin de garantir que l'anneau indicateur des unités va rester immobile lors du passage du « 31 » d'un mois au « 01 » du mois suivant.The object of the present invention is to solve the problem explained above by providing a large date display mechanism in which the indexing of a pinion located in the kinematic chain which drives an indicator ring of the units is ensured, even when this pinion is not in mesh with a driving wheel with which it meshes normally in order to guarantee that the units indicator ring will remain stationary during the passage of the “31” from one month to the next. "01" of the following month.

A cet effet, la présente invention concerne un mécanisme d'affichage de quantième grande date entraîné via une chaîne cinématique par un mouvement d'horlogerie d'une pièce d'horlogerie équipée de ce mécanisme d'affichage de quantième grande date, ce mécanisme d'affichage de quantième grande date comprenant un premier indicateur de quantième sur lequel sont reportées les indications des unités de quantième de « 0 » à « 9 », et un second indicateur de quantième sur lequel sont reportées les indications des dizaines de quantième de « 0 » à « 3 », toutes les indications de quantième de « 01 » à « 31 » pouvant être obtenues par combinaison des indications des unités de quantième « 0 » à « 9 » portées par le premier indicateur de quantième avec les indications des dizaines de quantième « 0 » à « 3 » portées par le second indicateur de quantième, le premier indicateur de quantième restant immobile durant le passage du dernier jour d'un mois de 31 jours au premier jour du mois suivant, la chaîne cinématique comprenant une roue continûment en prise avec le mouvement d'horlogerie et qui présente un périmètre muni de dents via lesquelles la roue engrène avec un pignon qui lui-même participe à l'entraînement du premier indicateur des unités de quantième, la roue étant, en un endroit de son périmètre, dépourvue de dent afin que, durant le passage du dernier jour d'un mois de 31 jours au premier jour du mois suivant, la roue n'engrène pas avec le pignon qui, de même que le premier indicateur de quantième, reste ainsi immobile, le mécanisme d'affichage de quantième grande date comprenant également un sautoir double monté à pivotement autour d'un axe et qui comprend un premier bec par lequel il est en prise avec une denture du premier indicateur de quantième et un second bec par lequel il est en prise avec une denture du pignon, le sautoir double étant maintenu élastiquement en prise avec le premier indicateur de quantième et avec le pignon.To this end, the present invention relates to a large date date display mechanism driven via a kinematic chain by a timepiece movement of a timepiece equipped with this large date display mechanism, this large date display mechanism. 'large date date display comprising a first date indicator on which are shown the indications of the date units from "0" to "9", and a second date indicator on which are shown the indications of the tens of date of "0""To" 3 ", all date indications from "01" to "31" which can be obtained by combining the indications of the date units "0" to "9" carried by the first date indicator with the indications of the tens of date "0" to "3" carried by the second date indicator, the first date indicator remaining stationary during the passage from the last day of a 31-day month to the first day of the following month, the kinematic chain comprising a wheel continuously engaged with the clockwork movement and which has a perimeter provided with teeth via which the wheel meshes with a pinion which itself participates in driving the first indicator of the date units, the wheel being, at one point on its perimeter, devoid of teeth so that, during the passage from the last day of a 31-day month to the first day of the following month, the wheel does not mesh with the pinion which, like the first date indicator, thus remains stationary, the display mechanism large date calendar age also comprising a double jumper mounted to pivot about an axis and which comprises a first spout by which it engages with a toothing of the first date indicator and a second spout by which it engages with a toothing of the pinion, the double jumper being held elastically in engagement with the first date indicator and with the pinion.

Selon une forme spéciale d'exécution de l'invention, le sautoir double comprend une première extrémité à laquelle est prévu le premier bec, et une seconde extrémité à laquelle est prévu le second bec.According to a special embodiment of the invention, the double jumper comprises a first end at which the first spout is provided, and a second end at which the second spout is provided.

L'invention concerne également une pièce d'horlogerie comprenant un mécanisme d'affichage de quantième grande date du type précisé ci-dessus.The invention also relates to a timepiece comprising a large date calendar display mechanism of the type specified above.

Grâce à ces caractéristiques, la présente invention procure un mécanisme d'affichage de quantième grande date dans lequel le positionnement d'un pignon qui participe à l'entraînement de l'indicateur des unités de quantième est constamment garanti, même lorsque ce pignon est libre de toute prise avec une roue via laquelle il est entraîné par le mouvement d'horlogerie de la pièce d'horlogerie équipée de ce mécanisme d'affichage de quantième grande date.Thanks to these characteristics, the present invention provides a large date display mechanism in which the positioning of a pinion which participates in driving the indicator of the date units is constantly guaranteed, even when this pinion is free. from any socket with a wheel via which it is driven by the clockwork movement of the timepiece fitted with this large date display mechanism.

Il est en effet nécessaire que, lors du passage d'un mois de 31 jours au premier jour du mois suivant, le pignon soit découplé du mouvement d'horlogerie afin que l'indicateur des unités de quantième reste immobile durant cette période. Effectivement, le marquage « 1 » porté par l'indicateur des unités de quantième est utilisé à la fois pour composer l'indication de quantième « 31 » à la fin d'un mois de 31 jours, et pour composer l'indication de quantième « 01 » au début du mois suivant. Il est donc indispensable que l'indicateur des unités de quantième reste immobile durant ce laps de temps afin que l'indication de date qui apparaît à travers un guichet ménagé dans un cadran de la pièce d'horlogerie soit exacte. Par suite, il faut découpler le pignon afin que le mouvement d'horlogerie qui fonctionne en permanence ne puisse entraîner l'indicateur des unités de quantième.It is in fact necessary that, during the passage from a month of 31 days to the first day of the following month, the pinion is decoupled from the clockwork movement so that the date units indicator remains stationary during this period. Indeed, the marking "1" carried by the date units indicator is used both to compose the date indication "31" at the end of a month of 31 days, and to compose the date indication. "01" at the start of the following month. It is therefore essential that the indicator of the date units remains stationary during this period of time so that the date indication which appears through a window in a dial of the timepiece is accurate. Consequently, the pinion must be decoupled so that the clockwork movement which operates continuously cannot drive the indicator of the date units.

On comprendra cependant aisément que le fait que le pignon soit momentanément découplé de la roue qui l'entraîne en temps normal pose problème dans la mesure où le positionnement de ce pignon ne peut être assuré durant cette période. Par conséquent, lorsque la roue va tourner et va se retrouver dans une position dans laquelle elle est à nouveau en mesure d'engrener avec le pignon, il se peut que ce pignon ne soit pas convenablement positionné et qu'il soit impossible à la roue de revenir en prise avec ce pignon, ce qui conduit au blocage du mécanisme. Il est donc indispensable de pouvoir constamment garantir la bonne indexation du pignon, en particulier durant la période où ce pignon n'est pas en prise avec la roue qui l'entraîne le restant du temps.However, it will easily be understood that the fact that the pinion is momentarily decoupled from the wheel which drives it in normal times poses a problem insofar as the positioning of this pinion cannot be ensured during this period. Therefore, when the wheel will turn and come to a position in which it is again able to mesh with the pinion, it may be that this pinion is not properly positioned and it is impossible for the wheel to come back into engagement with this pinion, which leads to the locking of the mechanism. It is therefore essential to be able to constantly guarantee the correct indexing of the pinion, in particular during the period when this pinion is not in engagement with the wheel which drives it the rest of the time.

De même, le sautoir double est en prise avec une denture de l'indicateur des unités de quantième afin d'assurer en permanence le bon positionnement de l'indication de l'unité de quantième dans le guichet percé dans le cadran de la pièce d'horlogerie.Likewise, the double jumper is engaged with a toothing of the date units indicator in order to permanently ensure the correct positioning of the indication of the date unit in the aperture pierced in the dial of the part of the date. watchmaking.

On notera que, comme le sautoir double est articulé à pivotement, il est dégagé de sa prise avec le pignon lorsqu'il est repoussé par la denture du premier indicateur de quantième, et inversement.It will be noted that, as the double jumper is pivotally articulated, it is released from its engagement with the pinion when it is pushed back by the teeth of the first date indicator, and vice versa.

Description détaillée d'un mode de réalisation de l'inventionDetailed description of an embodiment of the invention

La présente invention procède de l'idée générale inventive qui consiste, dans un mécanisme d'affichage de quantième grande date, à assurer simultanément, au moyen d'un sautoir double unique, le bon positionnement d'un pignon et d'un indicateur des unités de quantième entraîné par ce pignon, en particulier durant le laps de temps où, pour empêcher le pivotement de l'indicateur des unités de quantième, le pignon n'est plus en prise avec la roue qui, en temps normal, transmet à ce pignon l'énergie fournie par le mouvement d'horlogerie de la pièce d'horlogerie équipée du mécanisme d'affichage de quantième grande date selon la présente invention.The present invention proceeds from the general inventive idea which consists, in a large date display mechanism, in simultaneously ensuring, by means of a single double jumper, the correct positioning of a pinion and of an indicator. date units driven by this pinion, in particular during the period of time when, to prevent the pivoting of the date units indicator, the pinion is no longer in mesh with the wheel which, under normal circumstances, transmits to this pinion the energy supplied by the clockwork movement of the timepiece equipped with the large date display mechanism according to the present invention.

Désigné dans son ensemble par la référence numérique générale 1 et comme visible sur la figure 1 annexée à la présente demande de brevet, le mécanisme d'affichage de grande date équipe une pièce d'horlogerie 2 telle qu'une montre-bracelet qui comprend un cadran 4 dans lequel est ménagé un guichet 6 à travers lequel est visible une indication de grande date 8.Designated as a whole by the general reference numeral 1 and as visible on the figure 1 appended to the present patent application, the large date display mechanism equips a timepiece 2 such as a wristwatch which comprises a dial 4 in which is formed a window 6 through which is visible an indication of big date 8.

En se référant maintenant à la figure 2, on voit que le mécanisme d'affichage de grande date 1 comprend un renvoi au centre 10 qui est classiquement solidaire d'une roue des heures entraînée par une minuterie d'un mouvement d'horlogerie (non représentés). Ce renvoi au centre 10 engrène avec une roue entraîneuse de came 12 qui est entraînée à raison d'un tour par jour. Cette roue entraîneuse de came 12 entraîne à son tour une roue de came 14 sur laquelle est fixée une came 16.Referring now to the figure 2 , it can be seen that the large date display mechanism 1 comprises a reference to the center 10 which is conventionally integral with an hour wheel driven by a timer of a clockwork movement (not shown). This return to the center 10 meshes with a cam drive wheel 12 which is driven at the rate of one revolution per day. This cam drive wheel 12 in turn drives a cam wheel 14 on which a cam 16 is fixed.

La roue entraîneuse de came 12 et la roue de came 14 sont liées cinématiquement entre elles au moyen d'une goupille 18 chassée dans la roue de came 14 et qui passe librement à travers un trou oblong 20 ménagé dans la roue entraîneuse de came 12 (voir figure 5). Lorsque la roue entraîneuse de came 12 tourne, elle entraîne la roue de came 14 grâce à la goupille 18 qui bute contre un rebord intérieur 20a du trou oblong 20. La came 16 présente un profil 16a en un endroit duquel est prévu un décrochement 16b. Une bascule de déclenchement 22, contrainte élastiquement par un ressort 24, comprend un bec 26 par lequel elle suit le profil 16a de la came 16.The cam drive wheel 12 and the cam wheel 14 are kinematically linked together by means of a pin 18 driven into the cam wheel 14 and which passes freely through an oblong hole 20 made in the cam drive wheel 12 ( to see figure 5 ). When the cam drive wheel 12 rotates, it drives the cam wheel 14 by virtue of the pin 18 which abuts against an inner rim 20a of the oblong hole 20. The cam 16 has a profile 16a at a location of which a step 16b. A trigger lever 22, elastically constrained by a spring 24, comprises a beak 26 through which it follows the profile 16a of the cam 16.

Une fois par jour, aux alentours de minuit, la bascule de déclenchement 22 tombe le long du décrochement 16b du profil 16a de la came 16 et provoque le pivotement instantané de la roue de came 14 d'un angle qui est défini par le décrochement 16b du profil 16a de la came 16. On notera que les dimensions du trou oblong 20 sont suffisantes pour permettre à la roue de came 14 d'effectuer son mouvement de pivotement instantané sans être gênée par la goupille 18.Once a day, around midnight, the trigger lever 22 falls along the step 16b of the profile 16a of the cam 16 and causes the instantaneous pivoting of the cam wheel 14 by an angle which is defined by the step 16b of the profile 16a of the cam 16. It will be noted that the dimensions of the oblong hole 20 are sufficient to allow the cam wheel 14 to perform its instantaneous pivoting movement without being hampered by the pin 18.

La roue de came 14 entraîne une roue entraîneuse de quantième 28 qui porte un doigt 30 par lequel la roue entraîneuse de quantième 28 commande, une fois par jour, l'avance d'une roue de trente-et-une dents 32 d'un pas (voir figure 3). Par ailleurs, une roue de programmation 34 est fixée sur la roue de trente-et-une dents 32. La roue à trente-et-une dents 32 engrène à son tour avec une roue entraîneuse 36 elle-même en prise avec un pignon intermédiaire 38 d'un mobile intermédiaire 40. Finalement, une roue intermédiaire 42 du mobile intermédiaire 40 engrène avec un pignon entraîneur des unités 44 d'un mobile entraîneur des unités 46 dont une roue entraîneuse des unités 48 entraîne un indicateur des unités de quantième. A titre d'exemple illustratif et non limitatif seulement, cet indicateur des unités de quantième se présente sous la forme d'un anneau 50. Cet anneau indicateur des unités 50 porte les indications « 0 », « 1 », « 2 », « 3 », « 4 », « 5 », « 6 », « 7 », « 8 » et « 9 » qui correspondent aux indications des unités du quantième et avance à raison d'un pas par jour, excepté lors du passage du « 31 » d'un mois au « 1 » du mois suivant.The cam wheel 14 drives a date drive wheel 28 which carries a finger 30 by which the date drive wheel 28 controls, once a day, the advance of a wheel of thirty-one teeth 32 by one. no see figure 3 ). Furthermore, a programming wheel 34 is attached to the thirty-one tooth wheel 32. The thirty-one tooth wheel 32 in turn meshes with a drive wheel 36 which itself engages with an intermediate gear. 38 of an intermediate mobile 40. Finally, an intermediate wheel 42 of the intermediate mobile 40 meshes with a drive pinion of the units 44 of a drive wheel of the units 46 of which a drive wheel of the units 48 drives an indicator of the date units. By way of illustrative and non-limiting example only, this date units indicator is in the form of a ring 50. This units indicator ring 50 bears the indications “0”, “1”, “2”, “ 3 "," 4 "," 5 "," 6 "," 7 "," 8 "and" 9 "which correspond to the indications of the date units and advance at the rate of one step per day, except when passing through the “31” from one month to “1” of the following month.

La roue de programmation 34 est munie de quatre dents 34a, 34b, 34c et 34d par lesquelles cette roue de programmation 34 entraîne d'un pas tous les 10 jours une étoile à quatre dents 52 sur laquelle est fixé un indicateur des dizaines de quantième. A titre d'exemple illustratif et non limitatif seulement, cet indicateur des dizaines de quantième est conçu sous la forme d'un disque 54. Le disque indicateur des dizaines 54 porte les indications « 0 », « 1 », « 2 » et « 3 » qui correspondent aux indications des dizaines du quantième.The programming wheel 34 is provided with four teeth 34a, 34b, 34c and 34d by which this programming wheel 34 drives by one step every 10 days a star with four teeth 52 on which is fixed a tens of date indicator. By way of illustrative and non-limiting example only, this indicator of the tens of the date is designed under the shape of a disc 54. The tens indicator disc 54 bears the indications "0", "1", "2" and "3" which correspond to the tens indications of the date.

Comme mentionné ci-dessus, l'anneau indicateur des unités 50 avance d'un pas par jour, excepté lors du passage du « 31 » d'un mois au « 1 » du mois suivant. Au cours de ce passage, l'anneau indicateur des unités 50 doit rester immobile. En effet, le marquage « 1 » porté par l'indicateur des unités de quantième est utilisé à la fois pour composer l'indication de quantième « 31 » à la fin d'un mois de 31 jours, et pour composer l'indication de quantième « 01 » au début du mois suivant. Il est donc indispensable que l'anneau indicateur des unités 50 reste immobile durant ce laps de temps afin que l'indication de date qui apparaît à travers le guichet 6 ménagé dans le cadran 4 de la pièce d'horlogerie 2 soit exacte.As mentioned above, the units indicator ring 50 advances one step per day, except when changing from "31" of one month to "1" of the following month. During this passage, the indicator ring of the 50 units must remain stationary. In fact, the marking "1" carried by the date units indicator is used both to compose the date indication "31" at the end of a month of 31 days, and to compose the date indication. date "01" at the start of the following month. It is therefore essential that the indicator ring of the units 50 remains stationary during this period of time so that the date indication which appears through the window 6 provided in the dial 4 of the timepiece 2 is exact.

Pour atteindre cet objectif, deux dents d'une denture 56 de trente-et-une dents de la roue entraîneuse 36 sont manquantes et laissent un espace vide 57 (voir figure 4). Ainsi, lorsque cette portion dépourvue de dent de la denture 56 de trente-et-une dents de la roue entraîneuse 36 fait face à une denture 58 du pignon intermédiaire 38, la position angulaire de ce pignon intermédiaire 38 n'est plus convenablement assurée, ce qui, en bout de chaîne cinématique, ne permet plus de garantir le bon positionnement de l'indication « 1 » portée par l'anneau indicateur des unités 50 dans le guichet 6 ménagé dans le cadran 4 de la pièce d'horlogerie 2. Bien entendu, ce problème n'est pas acceptable.To achieve this objective, two teeth of a toothing 56 of thirty-one teeth of the driving wheel 36 are missing and leave an empty space 57 (see figure 4 ). Thus, when this toothless portion of the teeth 56 of thirty-one teeth of the driving wheel 36 faces a toothing 58 of the intermediate pinion 38, the angular position of this intermediate pinion 38 is no longer suitably ensured, which, at the end of the kinematic chain, no longer makes it possible to guarantee the correct positioning of the indication "1" carried by the indicator ring of the units 50 in the window 6 provided in the dial 4 of the timepiece 2. Of course, this problem is not acceptable.

C'est pourquoi, conformément à l'invention, il est proposé d'équiper le mécanisme d'affichage de grande date d'un sautoir double 60 agencé à pivotement autour d'un centre O. Ce sautoir double 60 est muni d'un premier bec 60a par lequel il est en prise avec une denture intérieure 62 de l'anneau indicateur des unités 50, et d'un second bec 60b par lequel il est en prise avec la denture 58 du pignon intermédiaire 38. Le sautoir double 60 est maintenu en appui élastique contre la denture 58 du pignon intermédiaire 38 et contre la denture intérieure 62 de l'anneau indicateur des unités 50 par un ressort 64. Lorsque le pignon intermédiaire 38 avance d'un pas, le sautoir double 60 pivote autour de son centre de pivotement O et son bec 60b s'efface en passant du creux entre deux dents consécutives de la denture 58 de ce pignon intermédiaire 38 au creux suivant. Simultanément, le premier bec 60a du sautoir double 60 se dégage du creux entre les deux dents de la denture intérieure 62 de l'anneau indicateur des unités 50 et tombe dans le creux suivant. La géométrie du sautoir double 60 et le positionnement de son centre de pivotement O sont tels que lorsque le sautoir double 60 pivote, il se dégage simultanément de la denture 58 du pignon intermédiaire 38 et de la denture intérieure 62 de l'anneau indicateur des unités 50. Ainsi, lors du passage, à la fin d'un mois, de l'indication de quantième « 31 » à l'indication de quantième « 1 » du mois suivant, le pignon intermédiaire 38, bien que n'étant pas en prise avec la roue entraîneuse 36, est maintenu en position par le bec 60b du sautoir double 60, de sorte qu'il n'y a aucun risque que l'indication de quantième « 1 » ne soit pas convenablement centrée dans le guichet 6 ménagé dans le cadran 4 de la pièce d'horlogerie 2.This is why, in accordance with the invention, it is proposed to equip the large date display mechanism with a double jumper 60 arranged to pivot about a center O. This double jumper 60 is provided with a first nose 60a by which it engages with an internal toothing 62 of the indicator ring of the units 50, and of a second nose 60b by which it engages with the teeth 58 of the intermediate gear 38. The double jumper 60 is held in elastic support against the teeth 58 of the intermediate gear 38 and against the internal teeth 62 of the indicator ring units 50 by a spring 64. When the intermediate pinion 38 advances by one step, the double jumper 60 pivots around its pivoting center O and its beak 60b moves out of the hollow between two consecutive teeth of the toothing 58 from this intermediate pinion 38 to the following hollow. Simultaneously, the first beak 60a of the double jumper 60 emerges from the hollow between the two teeth of the internal toothing 62 of the indicator ring of the units 50 and falls into the following hollow. The geometry of the double jumper 60 and the positioning of its pivoting center O are such that when the double jumper 60 rotates, it disengages simultaneously from the teeth 58 of the intermediate gear 38 and from the internal teeth 62 of the indicator ring of the units. 50. Thus, when changing, at the end of a month, from the date indication "31" to the date indication "1" of the following month, the intermediate pinion 38, although not being in taken with the driving wheel 36, is held in position by the spout 60b of the double jumper 60, so that there is no risk that the date indication "1" is not properly centered in the aperture 6 provided in dial 4 of timepiece 2.

Comme on le voit sur le dessin, le premier bec 60a est prévu à une première extrémité du sautoir double 60, tandis que le second bec 60b est prévu à une seconde extrémité du sautoir double 60. On comprendra néanmoins qu'en fonction des contraintes de construction du mécanisme d'affichage, il est possible de prévoir deux becs 60a, 60b s'étendant depuis une même extrémité du sautoir double 60 selon deux rayons différents (voir figure 6).As can be seen in the drawing, the first spout 60a is provided at a first end of the double jumper 60, while the second spout 60b is provided at a second end of the double jumper 60. It will nevertheless be understood that depending on the constraints of construction of the display mechanism, it is possible to provide two nozzles 60a, 60b extending from the same end of the double jumper 60 along two different radii (see figure 6 ).

Le pignon intermédiaire 38 appartient au mobile intermédiaire 40 avec une roue intermédiaire 42 duquel il est couplé en rotation. Cette roue intermédiaire 42 engrène à son tour avec un pignon entraîneur des unités 44 d'un mobile entraîneur 46 de l'anneau indicateur des unités 50. Ce pignon entraîneur 44 est couplé en rotation avec la roue entraîneuse des unités 48 qui entraîne l'anneau indicateur des unités 50 par engrènement avec la denture intérieure 62 de cet anneau indicateur des unités 50.The intermediate pinion 38 belongs to the intermediate mobile 40 with an intermediate wheel 42 of which it is coupled in rotation. This intermediate wheel 42 in turn meshes with a drive pinion of the units 44 of a mobile drive 46 of the indicator ring of the units 50. This drive pinion 44 is rotatably coupled with the drive wheel of the units 48 which drives the ring. indicator of the units 50 by meshing with the internal toothing 62 of this indicator ring of the units 50.

Il va de soi que la présente invention n'est pas limitée au mode de réalisation qui vient d'être décrit et que diverses modifications et variantes simples peuvent être envisagées par l'homme du métier sans sortir du cadre de l'invention tel que défini par les revendications annexées. On notera en particulier que le nombre de dents de la denture 56 de la roue entraîneuse 36 peut être différent de trente-et-une dents et que le nombre de dents omises peut être différent de deux, par exemple égal à un ou à trois. On notera également que, selon les contraintes de construction du mécanisme d'affichage de grande date, les deux becs du sautoir double peuvent être agencés sur la même extrémité du sautoir, en s'étendant depuis cette extrémité selon deux rayons différents.It goes without saying that the present invention is not limited to the embodiment which has just been described and that various modifications and simple variants can be envisaged by those skilled in the art without departing from the scope of the invention as defined. by the appended claims. It will be noted in particular that the number of teeth of the teeth 56 of the driving wheel 36 may be different from thirty-one teeth and that the number of omitted teeth may be different from two, for example equal to one or three. It will also be noted that, depending on the construction constraints of the large date display mechanism, the two spouts of the double jumper can be arranged on the same end of the jumper, extending from this end along two different radii.
