Description

Domaine technique de l'inventionTechnical field of the invention

L'invention concerne un mécanisme d'affichage d'horlogerie à saut multiple, agencé pour être entraîné par un mobile d'entrée mû par un mouvement, pour l'affichage d'une grandeur sur une pluralité de positions discrètes, par au moins un afficheur en regard d'une échelle d'affichage, lesdites positions discrètes étant séparées deux à deux par des intervalles, chaque dit intervalle étant égal à un pas élémentaire, ou à un pas majoré supérieur audit pas élémentaire, ou à un multiple entier dudit pas élémentaire, et au moins un dit intervalle étant différent des autres.The invention relates to a multiple-jump clock display mechanism, arranged to be driven by an input wheel set moved by a movement, for displaying a quantity on a plurality of discrete positions, by at least one display facing a display scale, said discrete positions being separated two by two by intervals, each said interval being equal to an elementary step, or to an increased step greater than said elementary step, or to an integer multiple of said elementary step, and at least one said interval being different from the others.

L'invention concerne encore une pièce d'horlogerie, notamment une montre, comportant au moins un tel mécanisme d'affichage.The invention also relates to a timepiece, in particular a watch, comprising at least one such display mechanism.

L'invention concerne le domaine des mécanismes d'affichage d'horlogerie.The invention relates to the field of watch display mechanisms.

Arrière-plan technologiqueTechnological background

Dans la plupart des cas, les pièces d'horlogerie possèdent au moins un mécanisme d'affichage comprenant un indicateur qui pivote concentriquement à une graduation avec laquelle il coopère. Ce mécanisme d'affichage peut notamment être utilisé pour afficher l'heure ou le quantième. En général, les repères de la graduation sont répartis uniformément sur une circonférence.In most cases, timepieces have at least one display mechanism comprising an indicator that pivots concentrically to a graduation with which it cooperates. This display mechanism can in particular be used to display the time or the date. In general, the markings of the graduation are uniformly distributed around a circumference.

Dans le cas d'un affichage horaire ou de quantième central, c'est-à-dire lorsque l'indicateur pivote au centre du mouvement de la pièce d'horlogerie, cet indicateur balaie l'ensemble du cadran, et risque de masquer à un certain moment une complication ou un autre affichage qui serait placé dans un secteur du cadran.In the case of a central time or date display, that is to say when the indicator pivots at the center of the movement of the timepiece, this indicator sweeps the entire dial, and risks masking at a certain moment a complication or another display which would be placed in a sector of the dial.

On connait le document CH713209 qui décrit un mécanisme d'affichage qui résout ce problème par l'utilisation d'une came solidaire de l'indicateur.We know the document CH713209 which describes a display mechanism that solves this problem by using a cam integral with the indicator.

Par ailleurs, le document EP1351104 décrit un mécanisme d'affichage comprenant une roue de programme.Furthermore, the document EP1351104 describes a display mechanism comprising a program wheel.

Dans le cas d'un affichage horaire ou de quantième décentré, c'est-à-dire lorsque l'indicateur ne pivote pas au centre du mouvement de la pièce d'horlogerie, l'indicateur balaie une surface circulaire de petit diamètre, se situant généralement entre le centre du mouvement et le diamètre extérieur du cadran. La circonférence de cette surface étant petite, il est difficile d'y afficher l'intégralité des repères de la graduation surtout s'il s'agit de repères alphabétiques ou numériques. Il existe différents moyens de pallier ce problème, notamment en utilisant un repère alphabétique ou numérique, une graduation sur deux, et un repère de forme, tel que point, trait, ou similaire, pour les autres positions. Cette solution convient très bien pour les indications dont la quantité de graduations est un nombre pair, mais ne résout pas forcément le problème lorsque la quantité de graduations est un nombre impair. En effet, dans un tel cas il faut avoir la place d'inscrire la dernière graduation et la première l'une à côté de l'autre. Même s'il est possible d'afficher l'intégralité des chiffres, la lecture peut se révéler difficile pour l'utilisateur du fait de la proximité des chiffres.In the case of an off-center time or date display, that is to say when the indicator does not pivot at the center of the movement of the timepiece, the indicator scans a circular surface of small diameter, generally located between the center of the movement and the outer diameter of the dial. The circumference of this surface being small, it is difficult to display all of the graduation marks, especially if they are alphabetical or numeric marks. There are different ways of overcoming this problem, in particular by using an alphabetical or numeric mark, every other graduation, and a shape mark, such as a point, line, or similar, for the other positions. This solution is very suitable for indications whose number of graduations is an even number, but does not necessarily solve the problem when the number of graduations is an odd number. Indeed, in such a case, it is necessary to have space to write the last graduation and the first one next to each other. Even though it is possible to display the full digits, reading may be difficult for the user due to the proximity of the digits.

Résumé de l'inventionSummary of the invention

L'invention se propose de procurer un mécanisme d'affichage plus universel, dans lequel les repères de la graduation ne sont pas nécessairement répartis de manière uniforme sur une circonférence, mais sont disposés de sorte que la distance angulaire séparant deux repères consécutifs au choix est plus grande que la distance angulaire séparant les autres repères.The invention proposes to provide a more universal display mechanism, in which the graduation marks are not necessarily distributed uniformly over a circumference, but are arranged so that the angular distance separating two consecutive marks of choice is greater than the angular distance separating the other marks.

A cet effet, l'invention concerne un mécanisme d'affichage selon la revendication 1.For this purpose, the invention relates to a display mechanism according to claim 1.

L'invention concerne encore une pièce d'horlogerie, notamment une montre, comportant au moins un tel mécanisme d'affichage.The invention also relates to a timepiece, in particular a watch, comprising at least one such display mechanism.

Brève description des figuresBrief description of the figures

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée qui va suivre, en référence aux dessins annexés, où :

  • la figure 1 représente, de façon schématisée et en vue en plan, un mécanisme d'affichage d'horlogerie à saut multiple selon l'invention, appliqué à un cas particulier non limitatif d'affichage d'un quantième, dans une variante particulière où cet affichage saute, entre le repère « 31 » et le repère « 1 », d'un espace plus grand, appelé ici pas majoré, que les espaces ici équidistants séparant les autres repères appelés ici pas élémentaires. Ce mécanisme comporte un mobile d'entrée qui est un pignon d'entraînement agencé pour être entraîné par un mouvement d'horlogerie, et qui entraîne à son tour une roue de commande, qui est ici une roue de trente-et-un, et qui est solidaire d'une roue de saut multiple qui lui est coaxiale, et sous la roue de commande, et qui est représentée sur cette figure avec sa denture en trait continu, et avec sa serge et ses bras en trait interrompu; cette roue de commande est maintenue en position par un sautoir de saut multiple, la roue de saut multiple est donc ainsi maintenue en position également. La roue de commande coopère avec une roue indicatrice de quantième qui porte un afficheur visible sur les figures 4 à 8. Le mécanisme comporte un mécanisme de débrayage qui permet à la roue indicatrice de quantième, dans certaines positions, de ne pas être entraînée par la roue de commande, ce mécanisme de débrayage comporte ici une zone tronquée sur un niveau supérieur de denture de la roue indicatrice, qui ne comporte alors que 29 dents, tandis que le niveau inférieur de la roue indicatrice comporte 32 dents, qui sont identiques à celles du niveau supérieur, selon le même pas, et alignées avec celles qui subsistent. Ce niveau inférieur coopère constamment avec un sautoir d'indicateur de quantième, pour le maintien en position de la roue indicatrice. La roue indicatrice de quantième porte encore un entraîneur saillant, ici non limitativement, de sa face supérieure. Une deuxième chaîne cinématique part de la roue de saut multiple, qui commande, via un renvoi intermédiaire de saut multiple (dont l'engrènement avec la roue de saut multiple n'est pas représenté sur cette figure), la rotation d'un renvoi de saut multiple porteur d'un doigt de saut multiple, lequel peut, dans certaines positions angulaires respectives, pousser l'entraîneur de la roue indicatrice de quantième, pour provoquer la rotation de celle-ci d'une certaine valeur angulaire. Dans l'exemple illustré, la combinaison des dentures du rouage de la deuxième chaîne cinématique est telle que la poussée de l'entraîneur commande une rotation de la roue indicatrice avec un pas majoré qui est double du pas élémentaire ;
  • la figure 2 représente, de façon schématisée et en perspective, le mécanisme de la figure 1, dans la même configuration où le doigt de saut multiple vient au contact de l'entraîneur de la roue indicatrice de quantième ;
  • la figure 3 représente, de façon schématisée et en perspective la roue indicatrice de quantième seule ;
  • les figures 4 à 8 représentent, de façon schématisée et en vue en plan, l'évolution de la coopération des mobiles du même mécanisme, et l'évolution associée de l'affichage effectué par un afficheur qui est une aiguille montée solidaire de la roue indicatrice de quantième, face à un cadran portant une échelle d'affichage avec des repères chiffrés pour les jours de quantième impair, séparés par de simples points pour les jours de quantième pair ; cette échelle d'affichage comporte un pas élémentaire constant pour les intervalles entre les repères des jours de 1 à 31, et un intervalle majoré, qui est ici double du précédent, entre les repères 31 et 1. Sur ces figures la roue de commande est partiellement coupée pour laisser voir la roue de saut multiple et son engrènement avec le renvoi intermédiaire de saut multiple:
  • la figure 4 montre l'affichage du quantième 29, la zone tronquée de la roue indicatrice ne fait pas encore face à la denture de la roue de commande, le doigt de saut multiple est dans une position angulaire à 10 heures, et est encore distant de l'entraîneur de la roue indicatrice ;
  • la figure 5 montre l'affichage du quantième 30, la zone tronquée de la roue indicatrice arrive face à la denture de la roue de commande, le doigt de saut multiple est dans une position angulaire à 9 heures, et est encore distant de l'entraîneur de la roue indicatrice ;
  • la figure 6 montre l'affichage du quantième 31, qui correspond à la position des figures 1 et 2, la zone tronquée de la roue indicatrice fait face à la denture de la roue de commande qui ne peut alors plus l'entraîner, le doigt de saut multiple est dans une position angulaire à 8 heures, et est au contact de l'entraîneur de la roue indicatrice, prêt à provoquer le saut multiple ;
  • la figure 7 montre l'affichage du quantième 1, le saut multiple de deux pas élémentaires vient d'être effectué, la zone tronquée de la roue indicatrice s'éclipse par rapport à la denture de la roue de commande, qui peut désormais l'entraîner, le doigt de saut multiple est dans une position angulaire à 7 heures, et est proche de quitter le contact avec l'entraîneur de la roue indicatrice;
  • la figure 8 montre l'affichage du quantième 2, la zone tronquée de la roue indicatrice s'est éloignée de la denture de la roue de commande, qui coopère avec la denture du niveau supérieur de la roue indicatrice, le doigt de saut multiple est dans une position angulaire à 6 heures, et ne peut plus interférer avec l'entraîneur de la roue indicatrice jusqu'à la fin de mois suivante;
  • la figure 9 représente, de façon schématisée et en perspective, une autre variante de mécanisme d'affichage à saut multiple, où le doigt de saut multiple est porté par la roue de commande, et vient ici au contact de l'entraîneur de la roue indicatrice de quantième ;
  • la figure 10 représente, de façon schématisée et en perspective, l'autre côté de la variante de la figure 9 ;
  • la figure 11 représente, de façon schématisée et en vue en plan, une autre variante encore de mécanisme d'affichage à saut multiple, où la roue indicatrice comporte plusieurs zones tronquées et plusieurs entraîneurs, et où le doigt de saut multiple comporte une pluralité de doigts élémentaires, dont l'un vient ici au contact d'un des entraîneurs de la roue indicatrice de quantième ;
  • la figure 12 est un schéma-blocs représentant une montre comportant un mouvement qui entraîne le mobile d'entrée d'un mécanisme d'affichage à saut multiple selon l'invention.
Other features and advantages of the invention will become apparent upon reading the detailed description which follows, with reference to the appended drawings, where:
  • there figure 1 represents, schematically and in plan view, a multiple jump clock display mechanism according to the invention, applied to a particular non-limiting case of displaying a date, in a particular variant where this display jumps, between the mark "31" and the mark "1", by a larger space, here called an increased step, than the spaces here equidistant separating the other marks here called elementary steps. This mechanism comprises an input wheel which is a drive pinion arranged to be driven by a clockwork movement, and which in turn drives a control wheel, which is here a thirty-one wheel, and which is integral with a multiple jump wheel which is coaxial with it, and under the control wheel, and which is shown in this figure with its teeth in a continuous line, and with its felloe and arms in a broken line; this control wheel is held in position by a multiple jump jumper, the multiple jump wheel is thus thus held in position also. The control wheel cooperates with a date indicator wheel which carries a display visible on the Figures 4 to 8 The mechanism includes a disengagement mechanism which allows the date indicator wheel, in certain positions, not to be driven by the control wheel, this disengagement mechanism here includes a truncated zone on an upper level of teeth of the indicator wheel, which then only includes 29 teeth, while the lower level of the indicator wheel includes 32 teeth, which are identical to those of the upper level, according to the same pitch, and aligned with those which remain. This lower level constantly cooperates with a date indicator jumper, for maintaining the indicator wheel in position. The date indicator wheel also carries a projecting driver, here not limited to, from its upper face. A second kinematic chain starts from the multiple jump wheel, which controls, via an intermediate multiple jump return (whose meshing with the multiple jump wheel is not shown in this figure), the rotation of a multiple jump return bearing a multiple jump finger, which can, in certain respective angular positions, push the driver of the date indicator wheel, to cause the rotation of the latter by a certain angular value. In the example illustrated, the combination of the teeth of the gear train of the second kinematic chain is such that the thrust of the driver controls a rotation of the indicator wheel with an increased pitch which is double the elementary pitch;

In these figures the control wheel is partially cut away to reveal the multiple jump wheel and its mesh with the multiple jump intermediate gear:

Description détaillée de l'inventionDetailed description of the invention

L'invention concerne un mécanisme d'affichage 100 d'horlogerie, agencé pour être entraîné par un mobile d'entrée 1 mû par un mouvement 200, pour l'affichage d'une grandeur sur une pluralité de positions discrètes. Cet affichage est effectué par au moins un afficheur 11, tel qu'une aiguille, en regard d'une échelle d'affichage 12, les positions discrètes 12a, 12b, étant séparées deux à deux par des intervalles. Chaque intervalle est égal à un pas élémentaire PE, ou à un pas majoré PM supérieur au pas élémentaire PE, et notamment égal à un multiple entier du pas élémentaire, et au moins un intervalle est différent des autres.The invention relates to a timepiece display mechanism 100, arranged to be driven by an input wheel set 1 driven by a movement 200, for displaying a quantity on a plurality of discrete positions. This display is performed by at least one display 11, such as a hand, opposite a display scale 12, the discrete positions 12a, 12b, being separated two by two by intervals. Each interval is equal to an elementary step PE, or to an increased step PM greater than the elementary step PE, and in particular equal to an integer multiple of the elementary step, and at least one interval is different from the others.

Selon l'invention, le mécanisme 100 comporte un rouage pour la commande du mouvement de l'afficheur 11. Ce rouage comporte une roue de commande 2 en rotation continue, entraînée directement ou indirectement par le mobile d'entrée 1 ou constituant le mobile d'entrée 1. Cette roue de commande 2 est agencée pour entraîner une roue indicatrice 3 portant un afficheur 11, ou bien directement de la valeur d'un pas élémentaire PE par une coopération continue, directe ou indirecte, entre la roue de commande 2 et la roue indicatrice 3, ou bien indirectement au travers d'un mécanisme multiplicateur 50, par un moyen de débrayage du mécanisme d'entraînement par pas élémentaire, et par l'entraînement de la roue indicatrice 3, dans au moins une position de débrayage, par le mécanisme multiplicateur 50 l'entraînant d'un pas majoré PM supérieur au pas élémentaire PE.According to the invention, the mechanism 100 comprises a gear train for controlling the movement of the display 11. This gear train comprises a control wheel 2 in continuous rotation, driven directly or indirectly by the input wheel set 1 or constituting the input wheel set 1. This control wheel 2 is arranged to drive an indicator wheel 3 carrying a display 11, or else directly by the value of an elementary step PE by a continuous cooperation, direct or indirect, between the control wheel 2 and the indicator wheel 3, or indirectly through a multiplier mechanism 50, by a means of disengaging the drive mechanism by elementary step, and by the driving of the indicator wheel 3, in at least one disengaged position, by the multiplier mechanism 50 driving it by an increased step PM greater than the elementary step PE.

Plus particulièrement, la roue de commande 2 est agencée pour entraîner la roue indicatrice 3, ou bien directement de la valeur d'un pas élémentaire PE par une coopération continue, directe ou indirecte, entre la roue de commande 2 et la roue indicatrice 3, ou bien indirectement au travers d'un mécanisme multiplicateur 50 de la valeur d'un multiple entier du pas élémentaire, par un moyen de débrayage du mécanisme d'entraînement par pas élémentaire, et par l'entraînement de la roue indicatrice 3, dans au moins une position de débrayage, par le mécanisme multiplicateur 50 l'entraînant d'un pas majoré PM égal à un nombre entier de pas élémentaires PE, différent de un.More particularly, the control wheel 2 is arranged to drive the indicator wheel 3, either directly by the value of an elementary step PE by continuous cooperation, direct or indirect, between the control wheel 2 and the indicator wheel 3, or indirectly through a multiplier mechanism 50 of the value of an integer multiple of the elementary step, by a means of disengaging the drive mechanism by elementary step, and by driving the indicator wheel 3, in at least one disengaged position, by the multiplier mechanism 50 driving it by an increased step PM equal to an integer number of elementary steps PE, other than one.

Selon l'invention telle que revendiquée, la roue indicatrice 3 comporte, coaxiaux et synchrones, un niveau inférieur 3a à denture complète et en prise avec un premier sautoir 10 de maintien de la position d'affichage, et un niveau supérieur 3b coopérant directement ou via un rouage direct avec la roue de commande 2 sur une partie de sa circonférence, et comportant une denture localement tronquée, chaque zone tronquée 30 constituant un moyen de débrayage pour interrompre la chaîne cinématique entre le niveau supérieur 3b et la roue de commande 2. Le niveau inférieur 3a et le niveau supérieur 3b peuvent notamment former un ensemble monobloc.According to the invention as claimed, the indicator wheel 3 comprises, coaxial and synchronous, a lower level 3a with complete teeth and engaged with a first jumper 10 for maintaining the display position, and an upper level 3b cooperating directly or via a direct gear train with the control wheel 2 over part of its circumference, and comprising locally truncated teeth, each truncated zone 30 constituting a disengagement means for interrupting the kinematic chain between the upper level 3b and the control wheel 2. The lower level 3a and the upper level 3b can in particular form a single-piece assembly.

Plus particulièrement, la roue indicatrice 3, et par exemple dans le cas des figures le niveau supérieur 3b, comporte au moins un entraîneur 8, 80, qui est agencé pour coopérer avec au moins un doigt de saut multiple 7 entraîné directement ou indirectement par la roue de commande 2 et qui est agencé pour pousser cet au moins un entraîneur 8, 80, pour faire pivoter la roue indicatrice 3 selon une course angulaire supérieure à la course élémentaire correspondant au pas élémentaire PE, tant que le niveau supérieur 3b et la roue de commande 2 sont débrayés l'un de l'autre.More particularly, the indicator wheel 3, and for example in the case of the figures the upper level 3b, comprises at least one driver 8, 80, which is arranged to cooperate with at least one multiple jump finger 7 driven directly or indirectly by the control wheel 2 and which is arranged to push this at least one driver 8, 80, to pivot the indicator wheel 3 according to an angular travel greater than the elementary travel corresponding to the elementary step PE, as long as the upper level 3b and the control wheel 2 are disengaged from each other.

Plus particulièrement, le au moins un doigt de saut multiple 7 est agencé pour pousser cet au moins un entraîneur 8, 80, pour faire pivoter la roue indicatrice 3 selon une course angulaire correspondant à un nombre entier, différent de un, de pas élémentaires, tant que le niveau supérieur 3b et la roue de commande 2 sont débrayés l'un de l'autre.More particularly, the at least one multiple jump finger 7 is arranged to push this at least one driver 8, 80, to pivot the indicator wheel 3 according to an angular stroke corresponding to an integer number, different from one, of elementary steps, as long as the upper level 3b and the control wheel 2 are disengaged from each other.

Plus particulièrement, le mécanisme multiplicateur 50 comporte une roue de saut multiple 4, synchrone avec la roue de commande 2, qui entraîne un rouage multiplicateur auquel appartient un renvoi de saut multiple 6 qui porte le au moins un doigt de saut multiple 7.More particularly, the multiplier mechanism 50 comprises a multiple jump wheel 4, synchronous with the control wheel 2, which drives a multiplier gear to which belongs a multiple jump return 6 which carries the at least one multiple jump finger 7.

Plus particulièrement, le rouage multiplicateur comporte, entre la roue de saut multiple 4 et le renvoi de saut multiple 6, au moins un renvoi intermédiaire de saut multiple 5, et le nombre de dents des mobiles composant le rouage multiplicateur définit le rapport entre le pas majoré PM et le pas élémentaire PE.More particularly, the multiplier gear train comprises, between the multiple jump wheel 4 and the multiple jump return 6, at least one multiple jump intermediate return 5, and the number of teeth of the mobiles making up the multiplier gear train defines the ratio between the increased pitch PM and the elementary pitch PE.

Plus particulièrement encore, le rouage multiplicateur comporte, entre la roue de saut multiple 4 et le renvoi de saut multiple 6, au moins un renvoi intermédiaire de saut multiple 5, et le nombre de dents des mobiles composant le rouage multiplicateur définit la valeur du multiple entier du pas élémentaire.More particularly still, the multiplier gear train comprises, between the multiple jump wheel 4 and the multiple jump return 6, at least one multiple jump intermediate return 5, and the number of teeth of the mobiles making up the multiplier gear train defines the value of the integer multiple of the elementary step.

Plus particulièrement, le mécanisme 100 comporte un sautoir de saut multiple 9, qui est agencé pour maintenir la position de la roue de commande 2, et donc celle de la roue de saut multiple 4.More particularly, the mechanism 100 comprises a multiple jump jumper 9, which is arranged to maintain the position of the control wheel 2, and therefore that of the multiple jump wheel 4.

Plus particulièrement, le doigt de saut multiple 7 comporte une pluralité de doigts élémentaires 70, chacun agencé pour coopérer avec un entraîneur 8, 80.More particularly, the multiple jump finger 7 comprises a plurality of elementary fingers 70, each arranged to cooperate with a trainer 8, 80.

Plus particulièrement, la roue indicatrice 3 comporte un nombre maximal de dents qui est supérieur au nombre de dents que comporte la roue de commande 2, et la différence du nombre de dents entre la roue indicatrice 3 et la roue de commande 2 est le total des nombres de dents correspondant aux sauts majorés effectués par l'afficheur 11 sur une révolution de la roue indicatrice 3.More particularly, the indicator wheel 3 has a maximum number of teeth which is greater than the number of teeth which the control wheel 2 has, and the difference in the number of teeth between the indicator wheel 3 and the control wheel 2 is the total of the numbers of teeth corresponding to the increased jumps made by the display 11 on one revolution of the indicator wheel 3.

Plus particulièrement, le mécanisme 100 est un mécanisme de quantième, et comporte une roue de commande 2 à 31 dents, et une roue indicatrice 3 qui comporte au moins 32 dents pour séparer nettement l'affichage du 31ème jour du mois et celui du premier jour du mois suivant.More particularly, the mechanism 100 is a date mechanism, and comprises a control wheel 2 with 31 teeth, and an indicator wheel 3 which comprises at least 32 teeth to clearly separate the display of the 31st day of the month and that of the first day of the following month.

L'invention concerne encore une pièce d'horlogerie 500 comportant au moins un mouvement 200 agencé pour l'entraînement d'un tel mécanisme d'affichage 100, que comporte la pièce d'horlogerie 500.The invention also relates to a timepiece 500 comprising at least one movement 200 arranged for driving such a display mechanism 100, which the timepiece 500 comprises.

Les figures illustrent une variante particulière et non limitative de l'invention, qui est illustrée pour l'application à l'affichage d'un quantième. La description qui suit fait mention d'un double saut lorsque l'affichage effectue un pas majoré PM, c'est-à-dire un déplacement angulaire plus grand que le pas élémentaire PE. Cet exemple n'est nullement limitatif car le saut peut être d'une valeur différente, et notamment, dans l'application préférée où le pas majoré PM est un multiple du pas élémentaire PE, triple, quadruple ou davantage.The figures illustrate a particular and non-limiting variant of the invention, which is illustrated for the application to the display of a date. The description which follows mentions a double jump when the display performs an increased step PM, that is to say an angular displacement greater than the elementary step PE. This example is in no way limiting because the jump can be of a different value, and in particular, in the preferred application where the increased step PM is a multiple of the elementary step PE, triple, quadruple or more.

Le mobile d'entrée 1 est ici un pignon d'entraînement, qui est entraîné d'un pas par jour par un mouvement d'horlogerie 200.The input wheel 1 is here a drive pinion, which is driven one step per day by a clockwork movement 200.

La roue de commande 2 est ici une roue de trente et un, possédant 31 dents, et qui est entraînée par le pignon d'entraînement 1 et maintenue en place par un sautoir de saut multiple 9 qui est un sautoir de trente et un. La roue de commande 2 effectue donc un saut par jour, et un tour par mois, ce qui correspond au quantième standard.The control wheel 2 is here a wheel of thirty-one, having 31 teeth, and which is driven by the drive pinion 1 and held in place by a multiple jump jumper 9 which is a jumper of thirty-one. The control wheel 2 therefore makes one jump per day, and one revolution per month, which corresponds to the standard date.

La roue indicatrice 3 est ici une roue d'indication de quantième, qui est entraînée par la roue de commande 2, et est maintenue en place par le premier sautoir 10 qui est un sautoir d'indication de quantième. La roue indicatrice 3 possède 32 dents, et est composée de deux niveaux. Le niveau inférieur 3a est complet et comporte ces 32 dents, et est en contact permanent avec le premier sautoir 10 qui le maintient en position. Le niveau supérieur 3b, en contact avec la roue de commande 2 qui l'entraîne, possède un dégagement 30, ici sur 3 dents, afin de permettre un double saut au moment voulu sans pour autant entraîner la roue de commande 2.The indicator wheel 3 is here a date indicator wheel, which is driven by the control wheel 2, and is held in place by the first jumper 10 which is a date indicator jumper. The indicator wheel 3 has 32 teeth, and is composed of two levels. The lower level 3a is complete and has these 32 teeth, and is in permanent contact with the first jumper 10 which holds it in position. The level upper 3b, in contact with the control wheel 2 which drives it, has a clearance 30, here on 3 teeth, in order to allow a double jump at the desired moment without driving the control wheel 2.

La roue de saut multiple 4, qui est solidaire de la roue de commande 2, entraîne le renvoi intermédiaire de saut multiple 5, qui à son tour entraîne le renvoi de saut multiple 6 solidaire du doigt de saut multiple 7. Le rapport d'engrenage entre la roue de saut multiple 4 et le renvoi de saut multiple 6 définit la vitesse de rotation du doigt de saut multiple 7. Ce rapport d'engrenage doit être un nombre entier afin de garantir une position du doigt de saut multiple 7 identique à chaque révolution complète ou partielle de la roue de commande 2, pour cette application particulière. Dans cet exemple, un rapport de ½ a été choisi afin d'avoir une vitesse deux fois plus élevée sur le doigt de saut multiple 7.The multiple jump wheel 4, which is integral with the control wheel 2, drives the multiple jump intermediate gear 5, which in turn drives the multiple jump gear 6 integral with the multiple jump finger 7. The gear ratio between the multiple jump wheel 4 and the multiple jump gear 6 defines the rotational speed of the multiple jump finger 7. This gear ratio must be an integer in order to guarantee an identical position of the multiple jump finger 7 at each complete or partial revolution of the control wheel 2, for this particular application. In this example, a ratio of ½ has been chosen in order to have twice as much speed on the multiple jump finger 7.

Un entraîneur 8 est ici non limitativement constitué par une goupille, qui est solidaire de la roue indicatrice 3, et est agencée de sorte à être entraînée par le doigt de saut multiple 7 lorsque la roue de commande 2 ne peut pas entraîner la roue indicatrice 3 du fait de la présence du dégagement 30 sur le niveau supérieur 3b de cette dernière. La vitesse de rotation du doigt de saut multiple 7 étant plus élevée que la vitesse de rotation de la roue de commande 2, il en résulte un double saut pour la roue indicatrice 3, alors que la roue de commande 2 ne fait qu'un seul saut. Le mécanisme revient ensuite en position de départ et un nouveau cycle peut ainsi commencer pour la roue de commande 2 qui va à nouveau entraîner la roue indicatrice 3 pas par pas.A driver 8 is here non-limitingly constituted by a pin, which is integral with the indicator wheel 3, and is arranged so as to be driven by the multiple jump finger 7 when the control wheel 2 cannot drive the indicator wheel 3 due to the presence of the clearance 30 on the upper level 3b of the latter. The rotation speed of the multiple jump finger 7 being higher than the rotation speed of the control wheel 2, this results in a double jump for the indicator wheel 3, while the control wheel 2 only makes a single jump. The mechanism then returns to the starting position and a new cycle can thus begin for the control wheel 2 which will again drive the indicator wheel 3 step by step.

Naturellement certains composants du mécanisme peuvent être combinés pour former des ensembles monobloc, par exemple l'entraîneur 8 peut être monobloc avec la roue indicatrice 3.Naturally some components of the mechanism can be combined to form single-piece assemblies, for example the driver 8 can be single-piece with the indicator wheel 3.

Les repères de quantième 12 sont disposés de sorte que la distance angulaire PM séparant les repères 12a du jour selon le repère « 31 » et 12b du jour selon le repère « 1 » est plus grande que la distance angulaire PE séparant les autres repères.The date markers 12 are arranged so that the angular distance PM separating the day markers 12a according to the “31” marker and 12b of the day according to the “1” marker is greater than the angular distance PE separating the other markers.

L'aiguille d'indication de quantième 11, solidaire de la roue indicatrice 3, pivote concentriquement aux repères de quantième 12. L'aiguille d'indication de quantième 11 se trouve en face du repère 12a du jour selon le repère « 31 » lorsque le mécanisme est positionné juste avant le double saut, et va donc effectuer un déplacement angulaire plus grand lors du prochain saut pour ainsi se retrouver directement en face du repère 12b du jour selon le repère « 1 ».The date indicator hand 11, integral with the indicator wheel 3, pivots concentrically with the date markers 12. The date indicator hand 11 is located opposite the day marker 12a according to the “31” marker when the mechanism is positioned just before the double jump, and will therefore make a greater angular movement during the next jump to thus find itself directly opposite the day marker 12b according to the “1” marker.

Les déplacements angulaires de l'aiguille d'indication de quantième 11 sont donc réguliers durant toute la révolution de cette dernière jusqu'à arriver en face du repère 12a du jour selon le repère « 31 », et ainsi effectuer un déplacement angulaire plus grand entre les repères 12a du jour selon le repère « 31 »et 12b du jour selon le repère « 1 ».The angular movements of the date indicator hand 11 are therefore regular throughout the latter's revolution until it arrives opposite the day marker 12a according to the “31” marker, and thus performs a greater angular movement between the day markers 12a according to the “31” marker and 12b according to the “1” marker.

L'invention est avantageuse, car elle est facilement adaptable à différents types d'affichages.The invention is advantageous because it is easily adaptable to different types of displays.

En particulier, la distance angulaire du saut le plus grand peut être choisie en modifiant le nombre de dents de la roue indicatrice 3, la position de la goupille 8, la forme du doigt de saut multiple 7, ainsi que sa vitesse de rotation à l'aide du rapport d'engrenage entre la roue de saut multiple 4 et le renvoi de saut multiple 6.In particular, the angular distance of the largest jump can be chosen by changing the number of teeth of the indicator wheel 3, the position of the pin 8, the shape of the multiple jump finger 7, as well as its rotation speed using the gear ratio between the multiple jump wheel 4 and the multiple jump idler 6.

Il est également possible de multiplier le nombre de doigts de saut multiple 7 et de goupilles 8, afin que l'aiguille d'indication de quantième 11 effectue plusieurs sauts de pas majoré lors de sa révolution, tel que visible sur la figure 11, qui illustre une exécution particulière non limitative, et qui comporte une roue de commande 2 avec 35 dents pour permettre l'exécution de quatre sauts, en relation avec quatre dégagements 30 et quatre entraîneurs 80, le renvoi de saut multiple 6 comportant quant à lui deux doigts de saut multiple 70. Le rapport d'engrenage entre la roue de saut multiple 4 et le renvoi de saut multiple 6 doit être choisi en conséquence.It is also possible to multiply the number of multiple jump fingers 7 and pins 8, so that the date indicator hand 11 makes several increased step jumps during its revolution, as visible on the figure 11 , which illustrates a particular non-limiting execution, and which comprises a control wheel 2 with 35 teeth to allow the execution of four jumps, in relation to four releases 30 and four drivers 80, the multiple jump return 6 comprising two multiple jump fingers 70. The gear ratio between the multiple jump wheel 4 and the multiple jump return 6 must be chosen accordingly.

Il est, encore, possible de supprimer le rouage auxiliaire constitué par l'ensemble des mobiles 4, 5 et 6, et de placer le doigt de saut multiple 7 directement solidaire de la roue de trente et un 2.It is also possible to remove the auxiliary gear train consisting of all the mobiles 4, 5 and 6, and to place the multiple jump finger 7 directly attached to the thirty-one wheel 2.
