  • the distance between the dial and the date ring is very important.

In addition, four cuts are necessary in order to make the drive parts, and several new parts, including the date bridge, are added to the original frame for driving the needle.
  • This device therefore makes it possible to use the dial as an additional display member.
  • This solution is however difficult to apply if a large number of rotary indicators possibly rotating at different angular speeds must be provided in the watch.

  • Patent document CH 662 696 describes a watch movement comprising day and leap year indicators meshed by a zodiac wheel performing one revolution per year.

  • the date indicator 1 when it moves one step, acts on the indication control star 8; the control pinion 9 then drives the indication wheel 10, causing an angular displacement of the rotary indication means 12.
  • the value of this angular displacement depends on the number of teeth of the wheels and the gear ratios between the wheels and the gables. These are determined according to the type of indication. For example, in the case where the date is indicated ( Figures 2 and 4), the numbers of teeth and gear ratios are established so that the needle moves one step each day, following the same cycle as the date indicator. In the case of the moon phase indication, the cycle of the indication means 12 is slightly shorter than that of the date ring, so as to correspond to the real lunar cycle.
  • a clearance A is determined between the tooth 2 located downstream of the active tooth of the control star 8 and the latter tooth, this clearance existing when the date indicator 1 is in the stationary rest position, in order to shorten the duration of the "instantaneous jump". Indeed, it normally takes a certain time (typically 1 to 2 hours) for the date indicator to advance by one step. Game A delays the effect of tooth 2, the star 8 is thus driven for a shorter time. This time is also optimized by the action of the jumper 11 of the control star. In this way we succeed in dividing by four or more, the duration of the "instantaneous jump" at the level of the rotary indication means 12. For example, an “instantaneous jump" taking place in twenty minutes (or less) now becomes possible.
  • the clearance B between the tooth 2 located upstream of the active tooth of the control star 8 and the latter tooth makes it possible to avoid any disturbance of the means of indication if the crown is turned to the towards.
  • This play is also present when the date indicator 1 is in the stationary rest position.
  • the date ring can thus be moved angularly (upside down from the normal operating direction) over a distance corresponding to the clearance B, without the star 8 being driven.
  • more than one rotary indication means 12 is used (as for example in FIG. 6), either in a dependent manner, that is to say by coupling one or more additional sets, complete or partial, of wheels and pinions to one or the other of the drive elements 8, 9, 10, 16; either independently, that is to say by using one or more separate additional sets directly coupled to the date ring 1; or by combining these two methods.
  • the timepiece according to the invention therefore makes it possible, from a movement with known date indicator, and adding only drive wheels and pinions (8, 9, 10, 11), to drive at least one rotary indication means 12 in a simple and economical manner.
  • the elements added to the basic movement are simple, few and inexpensive (in particular the jumper 11 which can be constituted by a simple spring strip). In addition, they do not affect the dimensions of the basic movement.

Description

La présente invention concerne une pièce d'horlogerie comprenant un indicateur de quantième et au moins un moyen d'indication rotatif, entraîné par ledit indicateur de quantième, destiné à indiquer des paramètres cycliques tels le quantième, la phase lunaire, etc.The present invention relates to a timepiece comprising a date indicator and at least one rotary indication means, driven by said date indicator, intended to indicate cyclic parameters such as the date, the lunar phase, etc.

Le document EP 0 165 455 (Omega SA) décrit une pièce d'horlogerie dont le calendrier à aiguille d'affichage du quantième est entraîné par un anneau de quantième avec denture extérieure et des moyens de couplage. Un tel mouvement comporte de nombreux inconvénients: l'anneau de quantième comporte une denture extérieure. Cette denture n'existe vraisemblablement pas sur le mouvement d'origine puisqu'elle n'aurait eu, dans ce cas, aucune utilité. Il s'agit donc là d'une modification à apporter au mouvement d'origine afin de réaliser le mouvement revendiqué dans le document en question. De plus, la réalisation d'une telle denture implique d'importantes difficultés pour la fabrication en série, telles que les déformations de l'anneau, les problèmes de planéité, de taillage, etc. Ces problèmes peuvent être la source d'un taux de rejet très élevé. Le coût de production de cet anneau devient alors prohibitif. L'anneau de quantième avec denture extérieure est plus étroit que l'indicateur de quantième d'une montre avec guichet (col 2, lignes 32 à 39). En effet, avec un anneau plus large, il ne serait pas possible d'intégrer les différents éléments d'entraînement de l'aiguille d'affichage. L'anneau de quantième, tel que défini dans le document cité, ne peut donc pas être utilisé pour l'affichage du quantième par l'entremise d'un guichet, étant donné qu'il n'y a pas suffisamment d'espace pour y inscrire les chiffres. Cette fonction d'indication étant la fonction principale et essentielle d'un indicateur de quantième, tel que celui-ci est connu de l'état de la technique, l'anneau de quantième décrit dans le document cité a une forme, un fonctionnement, ainsi qu'une fonction essentiellement différentes d'un indicateur de quantième utilisé dans les montres à guichet de type connu. L'anneau de quantième décrit est simplement un anneau d'entraînement, avec denture interne conduite et denture externe conductrice. Par ailleurs, le support de cadran surélève l'ensemble. La distance entre le cadran et l'anneau de quantième est très importante. Avec une telle configuration, même si on arrivait à inscrire les chiffres de quantième sur l'anneau, l'affichage résultant ne présenterait pas de bonnes caractéristiques de lisibilité car les chiffres seraient trop éloignés du cadran. De plus, quatre taillages sont nécessaires afin de réaliser les pièces d'entraînement, et plusieurs pièces nouvelles, dont le pont de quantième, sont ajoutées au bâti original pour l'entraînement de l'aiguille.Document EP 0 165 455 (Omega SA) describes a timepiece whose calendar with date display needle is driven by a date ring with external toothing and coupling means. Such a movement has many drawbacks: the date ring has an external toothing. This set of teeth probably does not exist on the original movement since it would have been of no use in this case. This is therefore a modification to be made to the original movement in order to achieve the movement claimed in the document in question. In addition, the production of such a toothing implies significant difficulties for mass production, such as deformations of the ring, problems of flatness, cutting, etc. These problems can be the source of a very high rejection rate. The cost of producing this ring then becomes prohibitive. The date ring with external toothing is narrower than the date indicator of a watch with aperture (col 2, lines 32 to 39). Indeed, with a larger ring, it would not be possible to integrate the various drive elements of the display hand. The date ring, as defined in the cited document, cannot therefore be used to display the date through a window, since there is not enough space to enter the numbers. This indication function being the main and essential function of a date indicator, as it is known from the state of the art, the date ring described in the cited document has a form, an operation, as well as a function essentially different from a date indicator used in watches of known type. The date ring described is simply a drive ring, with driven internal toothing and conductive external toothing. Furthermore, the dial support raises the assembly. The distance between the dial and the date ring is very important. With such a configuration, even if it were possible to write the date numerals on the ring, the resulting display would not have good readability characteristics because the numbers would be too far from the dial. In addition, four cuts are necessary in order to make the drive parts, and several new parts, including the date bridge, are added to the original frame for driving the needle.

Le document de brevet CH 662 920 décrit un mouvement de montre dans lequel le cadran est entraîné en rotation par la denture interne de la roue des quantièmes. Un engrenage intermédiaire permet d'obtenir une vitesse de rotation du cadran d'un tour par année.Patent document CH 662 920 describes a watch movement in which the dial is rotated by the internal toothing of the date wheel. An intermediate gear provides a dial rotation speed of one revolution per year.

Ce dispositif permet donc d'utiliser le cadran comme organe supplémentaire d'affichage. Cette solution est toutefois difficile à appliquer si un grand nombre d'indicateurs rotatifs tournant éventuellement à des vitesses angulaires différentes doivent être prévus dans la montre. Dans ce cas, une pluralité de roues concentriques à la montre doivent être superposées, ce qui entraîne une surépaisseur importante de la montre. D'autre part, il est difficile d'obtenir un affichage lisible avec une pluralité d'indicateurs concentriques. Les differentes roues doivent en outre être placées à des distances différentes du cadran et du verre, ce qui nuit considérablement à l'esthétique et à la lisibilité de la montre.This device therefore makes it possible to use the dial as an additional display member. This solution is however difficult to apply if a large number of rotary indicators possibly rotating at different angular speeds must be provided in the watch. In this case, a plurality of wheels concentric with the watch must be superimposed, which results in a significant excess thickness of the watch. On the other hand, it is difficult to obtain a readable display with a plurality of concentric indicators. The different wheels must also be placed at different distances from the dial and the glass, which considerably affects the aesthetics and legibility of the watch.

Le document de brevet US-A-3 777 475 décrit un mouvement de montre comportant plusieurs indicateurs concentriques et qui souffre donc des mêmes difficultés et problèmes d'épaisseur si plusieurs indicateurs doivent être utilisés.Patent document US-A-3 777 475 describes a watch movement comprising several concentric indicators and which therefore suffers from same difficulties and problems of thickness if several indicators must be used.

Le document de brevet EP-A-0 366 610 décrit une montre dans laquelle divers organes indicateurs sont entraînés par une roue de rang de semaine. Ce type de roue est plutôt rare dans un mouvement de montre et doit donc être généralement ajouté aux éléments existants. Cette roue ne comporte pas de denture interne et ne remplit aucun rôle d'indicateur. Cette roue supplémentaire renchérissant le prix de mouvement ne remplit donc aucune autre fonction que d'entraîner divers indicateurs supplémentaires.Patent document EP-A-0 366 610 describes a watch in which various indicator members are driven by a week row wheel. This type of wheel is rather rare in a watch movement and must therefore generally be added to existing elements. This wheel has no internal toothing and does not serve as an indicator. This additional wheel increasing the movement price therefore fulfills no other function than driving various additional indicators.

Le document de brevet CH 662 696 décrit un mouvement de montre comprenant des indicateurs de jour et d'année bissextile engrenés par une roue de zodiaque effectuant un tour par année. Cette roue de zodiaque est peu fréquente dans les organes d'horlogerie et doit être généralement ajoutée au dispositif. Les indicateurs supplémentaires de jour et d'année bissextile sont engrenés directement, sans organe intermédiaire, par la roue de zodiaque, ce qui limite le choix de placement des indicateurs sur le cadran.Patent document CH 662 696 describes a watch movement comprising day and leap year indicators meshed by a zodiac wheel performing one revolution per year. This zodiac wheel is infrequent in watchmaking organs and must generally be added to the device. The additional day and leap year indicators are meshed directly, without an intermediate member, by the zodiac wheel, which limits the choice of placement of the indicators on the dial.

De manière similaire, le document de brevet CH-A-324 270 décrit un mouvement de montre comprenant une roue avançant de deux pas par 24 heures, et portant les indications d'unité de jour, qui entraîne un organe rotatif affichant les dizaines de jour.Similarly, patent document CH-A-324,270 describes a watch movement comprising a wheel advancing two steps per 24 hours, and bearing the day unit indications, which drives a rotary member displaying the tens of days .

Le but principal de la présente invention est donc de concevoir une pièce d'horlogerie de construction simplifiée offrant de plus vastes possibilités d'indications. Ce but est atteint grâce aux caractéristiques des revendications 1 à 15.The main purpose of the present invention is therefore to design a timepiece of simplified construction offering greater possibilities of indications. This object is achieved thanks to the features of claims 1 to 15.

La pièce d'horlogerie selon la présente invention permet l'affichage du quantième par l'entremise d'un guichet et/ou l'affichage d'au moins un paramètre cyclique, dont la durée peut être exprimée par une fonction temporelle, de manière dépendant du quantième, par l'entremise d'au moins un moyen d'affichage rotatif. L'indicateur de quantième utilisé est identique à celui de l'art antérieur, utilisé avec les montres à guichet de type connu; il conserve sa largeur originale et les chiffres indiquant le quantième peuvent y être inscrits. De cette façon, l'indicateur de quantième offre plus de possibilités d'indication qu'un simple anneau d'entraînement. L'indicateur de quantième comporte une denture interne dont les dents sont à la fois conduites et conductrices. La distance entre l'indicateur de quantième et le cadran reste faible, ce qui confère à l'ensemble une bonne lisibilité. Uniquement deux taillages sont nécessaires pour réaliser les pièces d'entraînement de l'affichage rotatif. Seul un sautoir (de coût minime) est ajouté au bâti. De plus, un jeu déterminé, situé entre les dents de l'étoile intermédiaire et celles de l'indicateur de quantième, remplie une double fonction: il permet de raccourcir la durée du passage de pas (saut) du moyen d'affichage rotatif et il évite toute perturbation dudit moyen si on tourne la couronne en deçà d'une limite angulaire donnée, en sens inverse du fonctionnement normal. Par ailleurs, le guichet indiquant le quantième peut être disposé à n'importe quelle position angulaire du cadran.The timepiece according to the present invention allows the display of the date through a window and / or the display of at least one cyclic parameter, the duration of which can be expressed by a time function, depending on the date, by means of at least one rotary display means. The date indicator used is identical to that of the prior art, used with aperture watches of known type; it retains its original width and the numbers indicating the date can be inscribed there. In this way, the date indicator offers more indication possibilities than a simple training ring. The date indicator has internal teeth, the teeth of which are both driven and conductive. The distance between the date indicator and the dial remains small, which gives the whole a good readability. Only two cuts are necessary to make the drive parts for the rotary display. Only a jumper (of minimal cost) is added to the frame. In addition, a determined clearance, located between the teeth of the intermediate star and those of the date indicator, fulfills a double function: it makes it possible to shorten the duration of the passage of step (jump) of the rotary display means and it avoids any disturbance of said means if the crown is rotated below a given angular limit, in the opposite direction to normal operation. Furthermore, the window indicating the date can be placed at any angular position on the dial.

La figure 1 représente un mouvement selon la présente invention où apparaissent uniquement les éléments nécessaires à la compréhension du présent exposé. Un indicateur de quantième 1, de type connu, est entraîné en rotation respectivement par la roue des heures 3 et la roue entraîneuse de quantième 4.

Grâce à ce type d'entraînement, l'indicateur 1 progresse d'un pas à chaque jour, ce déplacement s'effectuant dans l'intervalle de temps le plus court possible, de manière préférentielle à minuit. L'anneau 1 comporte trente et une dents 2, chacune d'elle correspondant à un jour du mois. Le sautoir 6 de l'anneau de quantième assure l'avance rapide de l'anneau 1 lorsque celui-ci est entraîné par la dent 5 de la roue entraîneuse de quantième, ainsi que son positionnement entre les pas.FIG. 1 represents a movement according to the present invention in which only the elements necessary for the understanding of the present description appear. A date indicator 1, of known type, is driven in rotation respectively by the hour wheel 3 and the date driving wheel 4. The first makes two turns per day, while the second performs only one turn per day. Thanks to this type of training, the indicator 1 progresses by one step each day, this movement taking place in the shortest possible time interval, preferably at midnight. Ring 1 has thirty-one teeth 2, each of them corresponding to a day of the month. The jumper 6 of the date ring ensures rapid advance of the ring 1 when the latter is driven by the tooth 5 of the date driving wheel, as well as its positioning between the steps.

Le dispositif décrit ci-dessus correspond à celui d'un mouvement de type connu, destiné à indiquer le quantième. Les indications de date 7 sont disposées dans l'ordre sur l'indicateur de quantième, dont la fonction principale consiste alors à indiquer le jour du mois par l'entremise d'un guichet prévu à cette fin dans le cadran.The device described above corresponds to that of a known type of movement, intended to indicate the date. The date indications 7 are arranged in order on the date indicator, the main function of which is then to indicate the day of the month through a window provided for this purpose in the dial.

La pièce d'horlogerie selon la présente invention utilise les éléments précédents, sans qu'il soit nécessaire de les modifier, afin d'entraîner au moins un moyen d'indication rotatif 12 (fig. 2 à 5), permettant d'indiquer tout paramètre cyclique dont la durée peut être exprimée par une fonction temporelle, de manière dépendant du quantième, comme par exemple la phase lunaire, le "cash balance", la date, ou autre. Une étoile de commande d'indication 8 engrène avec les dents 2 internes de l'indicateur 1. Un pignon 9, solidaire et coaxial à l'étoile 8, entraîne à son tour une roue d'indication 10 sur laquelle est disposé centralement un axe d'indication 16 (fig. 2). C'est cet axe d'indication qui entraîne le moyen d'indication rotatif 12. Le sautoir 11 de l'étoile de commande stabilise l'étoile de commande 8 entre les pas et règle l'avance rapide du moyen d'indication 12 afin de permettre un passage de pas qui soit le plus rapide possible.The timepiece according to the present invention uses the preceding elements, without it being necessary to modify them, in order to drive at least one rotary indication means 12 (fig. 2 to 5), making it possible to indicate any cyclic parameter, the duration of which can be expressed by a time function, depending on the date, such as for example the lunar phase, the "cash balance", the date, or other. An indication control star 8 meshes with the internal teeth 2 of the indicator 1. A pinion 9, integral and coaxial with the star 8, in turn drives an indication wheel 10 on which is centrally disposed an axis indication 16 (fig. 2). It is this axis of indication which drives the rotary indication means 12. The jumper 11 of the control star stabilizes the control star 8 between the steps and adjusts the rapid advance of the indication means 12 so to allow the quickest possible passage of steps.

Le moyen d'indication rotatif 12 peut varier selon la forme d'exécution et/ou selon le paramètre à indiquer. Par exemple, aux figures 2 et 4, le moyen d'indication rotatif 12 est une aiguille indiquant le quantième; à la figure 3, ainsi qu'à la figure 5 (à midi) le moyen 12 est un disque rotatif reproduisant le cycle lunaire à travers un guichet de forme adaptée de type connu; à la figure 5 (à 6 hres), le moyen 12 est une aiguille rotative indiquant le "cash balance", c'est-à-dire l'importance du solde bancaire (et/ou en argent liquide) encore disponible jusqu'au versement du prochain salaire. A la figure 5, l'indication de "cash balance" 7a est une bande circulaire dont la largeur diminue le long du parcours circulaire de l'aiguille indicatrice. Cette largeur est maximale au début du parcours (après le versement du salaire, par exemple au début du mois; le solde bancaire est alors important) et atteint son minimum par exemple vers la fin du mois, avant le versement du salaire suivant. Cette bande peut éventuellement être suivie d'une série de rainures disposées angulairement, tel que montré à la figure 5, pour les quelques jours précédents le versement du salaire, où le solde bancaire peut éventuellement devenir critique ou négatif. On remarque que l'indication de "cash balance" peut prendre une multitude de formes, où il suffit que la présentation visuelle montre l'évolution habituelle du solde bancaire en fonction du temps, de manière préférentielle en fonction des jours d'un mois. L'indication de "cash balance" 7a peut utiliser tout symbole, signe ou autre, fournissant une indication à l'utilisateur sur l'importance de son solde bancaire, comme par exemple une tirelire, représentée plus ou moins pleine selon l'importance du solde; un symbole monétaire, comme par exemple celui du dollar, représenté en différentes grosseurs proportionnellement à l'importance du solde bancaire, ce même symbole pouvant être accompagné d'une flèche dont la hauteur indique l'importance du solde (fig. 4), etc. Selon la variante montrée à la figure 4, les indications de "cash balance" 7a sont réparties sur l'indicateur de quantième 1 à la place des indications de date 7 qu'on retrouve sur les montres de type connu, pour être transmises par l'entremise d'un guichet 17. En outre, l'indication de "cash balance" 7a peut être utilisée avec'tout type de pièce d'horlogerie servant à indiquer le "cash balance".The rotary indication means 12 can vary according to the embodiment and / or according to the parameter to be indicated. For example, in Figures 2 and 4, the rotary indication means 12 is a hand indicating the date; in FIG. 3, as well as in FIG. 5 (at noon) the means 12 is a rotating disc reproducing the lunar cycle through a window of suitable shape of known type; in FIG. 5 (at 6 am), the means 12 is a rotary needle indicating the "cash balance", that is to say the size of the bank balance (and / or in cash) still available until payment of the next salary. In FIG. 5, the indication of "cash balance" 7a is a circular band whose width decreases along the circular path of the needle indicator. This width is maximum at the start of the journey (after the payment of the salary, for example at the beginning of the month; the bank balance is then significant) and reaches its minimum for example towards the end of the month, before the payment of the next salary. This strip may possibly be followed by a series of grooves arranged angularly, as shown in FIG. 5, for the few days preceding the payment of wages, where the bank balance may possibly become critical or negative. We note that the indication of "cash balance" can take a multitude of forms, where it suffices that the visual presentation shows the usual evolution of the bank balance as a function of time, preferably as a function of the days of a month. The indication of "cash balance" 7a can use any symbol, sign or other, providing an indication to the user on the size of his bank balance, such as for example a piggy bank, represented more or less full depending on the size of the balance; a monetary symbol, such as that of the dollar, represented in different sizes in proportion to the size of the bank balance, this same symbol can be accompanied by an arrow whose height indicates the size of the balance (fig. 4), etc. . According to the variant shown in FIG. 4, the “cash balance” indications 7a are distributed over the date indicator 1 in place of the date indications 7 which are found on watches of known type, to be transmitted by the 'through a window 17. In addition, the indication of "cash balance" 7a can be used with any type of timepiece used to indicate the "cash balance".

Selon d'autres variantes de la présente invention, un moyen d'indication rotatif 12 de type similaire à celui servant à indiquer le quantième peut également être utilisé pour indiquer le rang de la semaine dans le mois ou encore dans l'année.According to other variants of the present invention, a rotary indication means 12 of a type similar to that used to indicate the date may also be used to indicate the rank of the week in the month or in the year.

L'indicateur de quantième 1, lorsqu'il se déplace d'un pas, agit sur l'étoile de commande d'indication 8; le pignon de commande 9 entraîne alors la roue d'indication 10, provoquant un déplacement angulaire du moyen d'indication rotatif 12. La valeur de ce déplacement angulaire dépend du nombre de dents des roues et des rapports d'engrenages entre les roues et les pignons. Ceux-ci sont déterminés en fonction du type d'indication. Par exemple, dans le cas où on indique le quantième (figures 2 et 4), les nombres de dents et rapports d'engrenages sont établis de façon à ce que l'aiguille se déplace d'un pas à chaque jour, en suivant le même cycle que l'indicateur de quantième. Dans le cas de l'indication de phase de lune, le cycle du moyen d'indication 12 est légèrement plus court que celui de l'anneau de quantième, de façon à correspondre au cycle lunaire réel.The date indicator 1, when it moves one step, acts on the indication control star 8; the control pinion 9 then drives the indication wheel 10, causing an angular displacement of the rotary indication means 12. The value of this angular displacement depends on the number of teeth of the wheels and the gear ratios between the wheels and the gables. These are determined according to the type of indication. For example, in the case where the date is indicated (Figures 2 and 4), the numbers of teeth and gear ratios are established so that the needle moves one step each day, following the same cycle as the date indicator. In the case of the moon phase indication, the cycle of the indication means 12 is slightly shorter than that of the date ring, so as to correspond to the real lunar cycle.

De plus, afin de procurer un confort d'utilisation maximal, on détermine un jeu A entre la dent 2 située en aval de la dent active de l'étoile de commande 8 et cette dernière dent, ce jeu existant lorsque l'indicateur de quantième 1 est en position immobile de repos, afin de raccourcir la durée du "saut instantané". En effet, il faut normalement un certain temps (typiquement 1 à 2 heures) pour que l'indicateur de quantième avance d'un pas. Le jeu A retarde l'effet de la dent 2, l'étoile 8 est ainsi entraînée pendant un temps plus court. Ce temps est également optimisé grâce à l'action du sautoir 11 de l'étoile de commande. On réussit de cette façon à diviser par quatre ou plus, la durée du "saut instantané" au niveau du moyen d'indication rotatif 12. Par exemple, un "saut instantané" s'effectuant en vingt minutes (ou moins) devient maintenant possible.In addition, in order to provide maximum comfort of use, a clearance A is determined between the tooth 2 located downstream of the active tooth of the control star 8 and the latter tooth, this clearance existing when the date indicator 1 is in the stationary rest position, in order to shorten the duration of the "instantaneous jump". Indeed, it normally takes a certain time (typically 1 to 2 hours) for the date indicator to advance by one step. Game A delays the effect of tooth 2, the star 8 is thus driven for a shorter time. This time is also optimized by the action of the jumper 11 of the control star. In this way we succeed in dividing by four or more, the duration of the "instantaneous jump" at the level of the rotary indication means 12. For example, an "instantaneous jump" taking place in twenty minutes (or less) now becomes possible.

D'autre part, le jeu B entre la dent 2 située en amont de la dent active de l'étoile de commande 8 et cette dernière dent, permet d'éviter toute perturbation du moyen d'indication si la couronne est tournée à l'envers. Ce jeu est également présent lorsque l'indicateur de quantième 1 est en position immobile de repos. L'anneau de quantième peut ainsi être déplacé angulairement (à l'envers du sens normal de fonctionnement) sur une distance correspondant au jeu B, sans que l'étoile 8 soit entraînée.On the other hand, the clearance B between the tooth 2 located upstream of the active tooth of the control star 8 and the latter tooth, makes it possible to avoid any disturbance of the means of indication if the crown is turned to the towards. This play is also present when the date indicator 1 is in the stationary rest position. The date ring can thus be moved angularly (upside down from the normal operating direction) over a distance corresponding to the clearance B, without the star 8 being driven.

Selon une variante d'exécution, on utilise plus d'un moyen d'indication rotatif 12 (comme par exemple à la figure 6), soit de façon dépendante, c'est-à-dire en couplant un ou plusieurs jeux additionnels, complets ou partiels, de roues et pignons à l'un ou l'autre des éléments d'entraînement 8, 9, 10, 16; soit de façon indépendante, c'est-à-dire en utilisant un ou plusieurs jeux additionnels distincts couplés directement à l'anneau de quantième 1; ou encore en combinant ces deux méthodes.According to an alternative embodiment, more than one rotary indication means 12 is used (as for example in FIG. 6), either in a dependent manner, that is to say by coupling one or more additional sets, complete or partial, of wheels and pinions to one or the other of the drive elements 8, 9, 10, 16; either independently, that is to say by using one or more separate additional sets directly coupled to the date ring 1; or by combining these two methods.

La pièce d'horlogerie selon l'invention permet donc, à partir d'un mouvement avec indicateur de quantième de type connu, et en ajoutant uniquement des roues et pignons d'entraînement (8, 9, 10, 11), d'entraîner au moins un moyen d'indication rotatif 12 d'une façon simple et économique.The timepiece according to the invention therefore makes it possible, from a movement with known date indicator, and adding only drive wheels and pinions (8, 9, 10, 11), to drive at least one rotary indication means 12 in a simple and economical manner.

Les éléments ajoutés au mouvement de base sont simples, peu nombreux et peu coûteux (en particulier le sautoir 11 qui peut être constitué d'une simple lamelle à ressort). En outre, ils n'affectent pas les dimensions du mouvement de base.The elements added to the basic movement are simple, few and inexpensive (in particular the jumper 11 which can be constituted by a simple spring strip). In addition, they do not affect the dimensions of the basic movement.

Il est possible d'obtenir une multitude d'indications, combinées ou non. Par exemple, il est possible d'afficher le quantième par l'entremise d'un guirévélant les indications de date 7 inscrites sur l'indicateur de quantième 1, tout en ayant une indication de la phase lunaire et/ou du "cash balance" à l'aide d'un ou plusieurs moyens d'indications rotatifs 12.It is possible to obtain a multitude of indications, combined or not. For example, it is possible to display the date through a guirévélant the date indications 7 written on the date indicator 1, while having an indication of the lunar phase and / or of the "cash balance" using one or more means of rotary indications 12.

Il est également possible, selon une autre variante, de ne pas révéler les indications de date 7 inscrites sur l'anneau de quantième, en utilisant un guichet opaque ou en omettant le guichet; un ou plusieurs moyens d'indications rotatifs 12 permettent alors d'indiquer par exemple le quantième et/ou la phase lunaire et/ou le "cash balance" ou autre.It is also possible, according to another variant, not to reveal the date indications 7 inscribed on the date ring, by using an opaque window or by omitting the window; one or more rotary indication means 12 then make it possible to indicate, for example, the date and / or the lunar phase and / or the "cash balance" or the like.
