Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne un dispositif d'affichage d'une succession d'événements périodiques qui forment un cycle annuel. La présente invention concerne en particulier un dispositif d'affichage de la suite des périodes du zodiaque. La présente invention concerne également une pièce d'horlogerie comprenant un tel dispositif d'affichage.The present invention relates to a device for displaying a succession of periodic events which form an annual cycle. The present invention relates in particular to a device for displaying the sequence of periods of the zodiac. The present invention also relates to a timepiece comprising such a display device.

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

Un cycle annuel peut être divisé en un certain nombre de périodes qui comprennent chacune le même nombre de jours ou des nombres de jours différents.An annual cycle can be divided into a number of periods which each include the same number of days or different numbers of days.

A titre d'exemple, un cycle annuel de douze mois peut être divisé en douze périodes correspondant chacune à l'un des douze signes du zodiaque. La particularité de ces périodes zodiacales est que leurs durées ne sont pas identiques : ces durées sont en effet comprises entre 29 et 32 jours. Par ailleurs, le passage d'une période zodiacale à la période zodiacale suivante s'effectue entre le 20 et le 23 du mois concerné en fonction de la durée du signe du zodiaque en question. Par exemple, la période du zodiaque qui correspond au signe du sagittaire s'étend sur 29 jours depuis le 23 novembre jusqu'au 21 décembre, alors que la période du zodiaque qui correspond au signe du cancer dure 31 jours du 22 juin au 22 juillet.For example, an annual cycle of twelve months can be divided into twelve periods, each corresponding to one of the twelve signs of the zodiac. The peculiarity of these zodiac periods is that their durations are not identical: these durations are indeed between 29 and 32 days. In addition, the passage from a zodiac period to the following zodiac period takes place between the 20 and 23 of the month concerned depending on the duration of the zodiac sign in question. For example, the zodiac period which corresponds to the sign of the sagittarius extends over 29 days from November 23 to December 21, while the zodiac period which corresponds to the sign of cancer lasts 31 days from June 22 to July 22 .

Un cycle annuel peut également être divisé en douze périodes correspondant aux douze mois de l'année. Ces mois sont de durées inégales, comprises entre 28 et 31 jours.An annual cycle can also be divided into twelve periods corresponding to the twelve months of the year. These months are of unequal duration, between 28 and 31 days.

Des dispositifs d'affichage de ces périodes sont déjà connus. Les formes d'exécution les plus rudimentaires comprennent un disque sur lequel les différentes périodes d'un cycle annuel sont représentées au moyen de secteurs angulaires dont l'angle varie en fonction du nombre de jours de la période considérée. Une première forme d'exécution consiste à faire tourner le disque sous un cadran dans lequel est ménagé un guichet à travers lequel la période en cours est visible. Une autre forme d'exécution consiste à faire tourner le disque en regard d'un index qui pointe sur la période en cours. Une autre forme d'exécution encore consiste à faire tourner une aiguille au-dessus du disque, l'aiguille pointant sur la période en cours.Devices for displaying these periods are already known. The most rudimentary forms of execution include a disc on which the different periods of an annual cycle are represented by angular sectors whose angle varies according to the number of days of the period considered. A first embodiment consists in rotating the disc under a dial in which is provided a window through which the current period is visible. Another form of execution consists in turning the disc opposite an index which points to the current period. Yet another embodiment is to rotate a needle above the disc, the needle pointing to the current period.

Les mécanismes d'entraînement du disque sur lequel sont reportées les différentes périodes d'un cycle annuel ou bien de l'aiguille qui se déplace au-dessus d'un tel disque sont de type sautant ou traînant et leur avance est régulière, de sorte que l'affichage de la période en cours manque de précision, en particulier lors de la transition d'une période à la période suivante. Par ailleurs, afficher sur un élément d'une pièce d'horlogerie des indications temporelles d'étendues différentes alors que le temps, lui, s'écoule à un rythme égal, procure une perception assez médiocre des pièces d'horlogerie concernées.The drive mechanisms of the disc on which the different periods of an annual cycle are reported or of the needle which moves over such a disc are of the jumping or trailing type and their advance is regular, so that the display of the current period lacks precision, in particular when transitioning from one period to the next. Furthermore, displaying on a component of a timepiece time indications of different ranges while time itself is flowing at an equal rate, gives a rather poor perception of the timepieces concerned.

Un dispositif d'affichage de périodes formant un cycle annuel est connu par le document EP 3 029 531 A1 au nom de Blancpain. Le coeur de ce dispositif d'affichage est constitué par un mécanisme différentiel à deux entrées et une sortie. Une première entrée est constituée par une roue d'entraînement de référence agencée pour effectuer un tour selon une période de référence. Une seconde entrée est constituée par un organe d'activation agencé pour coopérer avec une came qui présente un profil agencé de façon que la coopération entre l'organe d'activation et le différentiel ait pour effet de faire avancer ou reculer un organe indicateur des périodes en fonction de la différence entre la période affichée et la période de référence. Enfin, la sortie est constituée par un organe d'entraînement de l'organe indicateur.A device for displaying periods forming an annual cycle is known from the document EP 3,029,531 A1 in the name of Blancpain. The heart of this display device is constituted by a differential mechanism with two inputs and one output. A first input is constituted by a reference drive wheel arranged to perform a revolution according to a reference period. A second inlet is constituted by an activation member arranged to cooperate with a cam which has a profile arranged so that the cooperation between the activation member and the Differential has the effect of advancing or retreating a period indicator according to the difference between the displayed period and the reference period. Finally, the output is constituted by a drive member of the indicator member.

Grâce à ces caractéristiques, le dispositif d'affichage Blancpain permet de représenter de manière régulière des périodes qui ne sont pas nécessairement toutes égales entre elles. Par ailleurs, le choix d'un mécanisme différentiel pour animer le dispositif d'affichage permet de positionner l'organe indicateur des périodes en un endroit quelconque du périmètre du cadran de la pièce d'horlogerie qui est équipée de ce dispositif d'affichage. Par contre, comme cela est bien connu, un mécanisme différentiel nécessite un grand nombre de pièces et est délicat à mettre au point. Par conséquent, un tel dispositif d'affichage est plutôt réservé à des pièces haut de gamme dont le prix de revient est élevé.Thanks to these characteristics, the Blancpain display device makes it possible to regularly represent periods which are not necessarily all equal to each other. Furthermore, the choice of a differential mechanism for animating the display device makes it possible to position the period indicator member at any location on the perimeter of the dial of the timepiece which is equipped with this display device. By cons, as is well known, a differential mechanism requires a large number of parts and is difficult to develop. Consequently, such a display device is rather reserved for high-end parts whose cost price is high.

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 à procurer un dispositif permettant d'afficher de manière égale et continue des évènements périodiques qui forment un cycle annuel et dont les durées ne sont pas égales. A cet effet, la présente invention procure un dispositif d'affichage comprenant une came entraînée par un dispositif indicateur de quantième et de mois et qui, chaque fin de mois où cela est nécessaire, pré-positionne une bascule de façon que, lorsque survient le jour du passage d'un évènement périodique à l'événement périodique immédiatement suivant, un organe d'affichage affiche l'événement périodique pertinent. Grâce à ces caractéristiques, la présente invention procure ainsi un dispositif d'affichage d'évènements périodiques formant un cycle annuel qui est continûment repositionné en fonction du jour du mois où débute l'événement périodique à considérer. Il est ainsi possible d'afficher des évènements périodiques qui ne se succèdent pas nécessairement de manière régulière dans le temps sans que cela soit perceptible par le propriétaire de la pièce d'horlogerie.The present invention proceeds from the general inventive idea which consists in providing a device making it possible to display in an equal and continuous manner periodic events which form an annual cycle and whose durations are not equal. To this end, the present invention provides a display device comprising a cam driven by a device indicating the date and month and which, at the end of each month where necessary, pre-positions a toggle so that, when the day of the transition from a periodic event to the immediately following periodic event occurs, a display unit displays the relevant periodic event. Thanks to these characteristics, the present invention thus provides a device for displaying periodic events forming an annual cycle which is continuously repositioned as a function of the day of the month when the periodic event to be considered begins. It is thus possible to display periodic events which do not necessarily follow one another regularly over time without this being perceptible by the owner of the timepiece.

Désigné dans son ensemble par la référence numérique générale 1, le dispositif d'affichage d'une succession d'évènements périodiques qui forment un cycle annuel selon l'invention comprend (voir les figures 1 et 2) un organe indicateur 2 des évènements périodiques sur lequel sont reportés les évènements périodiques à afficher. Le dispositif d'affichage 1 comprend également un mécanisme de gestion 4 d'une durée d'affichage des évènements périodiques. Ce mécanisme de gestion 4 comprend notamment un organe 6 agencé pour entraîner l'organe indicateur 2 des évènements périodiques lors d'un changement d'évènement. Le mécanisme de gestion 4 comprend également une came de gestion 8 de la durée d'affichage des évènements périodiques, et des moyens d'entraînement 10 de la came de gestion 8.Referred to as a whole by the general reference numeral 1, the device for displaying a succession of periodic events which form an annual cycle according to the invention comprises (see the figures 1 and 2 ) an indicator member 2 of the periodic events on which are reported the periodic events to be displayed. The display device 1 also includes a management mechanism 4 for a duration of display of the periodic events. This management mechanism 4 includes in particular a member 6 arranged to drive the indicator member 2 for periodic events during a change of event. The management mechanism 4 also comprises a management cam 8 for the duration of display of the periodic events, and means 10 for driving the management cam 8.

Plus précisément, le mécanisme de gestion 4 de la durée d'affichage des évènements périodiques comprend un mécanisme de quantième 12 entraîné par un mouvement d'horlogerie (non représenté). Ce mécanisme de quantième 12 est muni d'une roue entraîneuse de quantième 14 qui tourne à raison d'un tour complet par jour et qui comprend un doigt entraîneur de quantième 16. Chaque jour, aux alentours de minuit, la roue entraîneuse de quantième 14 fait avancer d'un pas, via son doigt entraîneur de quantième 16, une roue indicatrice de quantième 18 (voir figure 3).More specifically, the mechanism 4 for managing the duration of display of periodic events includes a date mechanism 12 driven by a clockwork movement (not shown). This date mechanism 12 is provided with a date driving wheel 14 which rotates at the rate of one complete revolution per day and which includes a date driving finger 16. Each day, around midnight, the driving wheel calendar 14 advances by one step, via its calendar driving finger 16, a calendar indicator wheel 18 (see figure 3 ).

La roue indicatrice de quantième 18 est munie d'un doigt entraîneur de mois 20 agencé sur un cercle concentrique à la roue indicatrice de quantième 18 (voir figure 4). Le 31 de chaque mois, ce doigt entraîneur de mois 20 fait avancer d'un pas une roue indicatrice de mois 22 sur laquelle est fixée la came de gestion 8 de la durée d'affichage des évènements périodiques. On comprend que la roue indicatrice de mois 22 et sa came de gestion 8 associée font un tour complet par an en avançant de 30° à la fin du 31 de chaque mois.The date indicator wheel 18 is provided with a month driving finger 20 arranged on a circle concentric with the date indicator wheel 18 (see figure 4 ). On the 31st of each month, this month driving finger 20 advances by one step a month indicator wheel 22 on which is fixed the management cam 8 of the duration of display of the periodic events. It is understood that the month indicator wheel 22 and its associated management cam 8 make one complete revolution per year, advancing 30 ° at the end of the 31st of each month.

L'information portée par la came de gestion 8 est communiquée à une bascule 24 montée concentriquement à la roue indicatrice de quantième 18 soit directement, soit, comme dans l'exemple représenté au dessin, via un marteau 26 muni d'un bec palpeur 28 qui suit le profil de la came de gestion 8 et contre lequel la bascule 24 est maintenue en appui élastique grâce à un ressort de rappel 30.The information carried by the management cam 8 is communicated to a lever 24 mounted concentrically with the date indicator wheel 18 either directly or, as in the example shown in the drawing, via a hammer 26 provided with a feeler spout 28 which follows the profile of the management cam 8 and against which the lever 24 is held in elastic support by means of a return spring 30.

Le dispositif d'affichage 1 décrit ici est agencé pour afficher la succession des 12 signes du zodiaque. On comprendra néanmoins que cet exemple est donné à titre purement illustratif seulement et que, moyennant une adaptation du profil de la came de gestion 8, il est tout à fait possible d'afficher une autre succession d'évènements périodiques ayant la particularité de former un cycle annuel. On pense en particulier à l'affichage de l'horoscope chinois.The display device 1 described here is arranged to display the succession of the 12 signs of the zodiac. It will nevertheless be understood that this example is given purely by way of illustration and that, with an adaptation of the profile of the management cam 8, it is entirely possible to display another succession of periodic events having the particularity of forming a annual cycle. We are thinking in particular of the display of the Chinese horoscope.

Dans le système zodiacal dit tropical auquel on s'intéresse ici, les 12 périodes du zodiaque commencent, selon le cas, le 20, le 21, le 22 ou le 23 du mois concerné. Par ailleurs, lorsque deux périodes du zodiaque successives ne commencent pas le même jour du mois, il n'y a jamais plus d'un jour de différence entre le début de la première période du zodiaque considéré et le début de la période du zodiaque immédiatement suivante. Plus précisément, de mars à mai, les périodes du zodiaque concernées, à savoir bélier, taureau et gémeaux, commencent toutes le 21 du mois. La période du zodiaque suivante, à savoir celle du cancer, débute quant à elle le 22 juin. De juillet à novembre, les périodes du zodiaque correspondantes, à savoir lion, vierge, balance, scorpion et sagittaire, commencent toutes le 23 du mois. En décembre, la période du capricorne commence le 22, en janvier, la période du verseau commence le 21, et en février, la période du poisson commence le 20.In the so-called tropical zodiac system in which we are interested here, the 12 periods of the zodiac begin, as the case may be, on 20, 21, 22 or 23 of the month concerned. Furthermore, when two successive zodiac periods do not start on the same day of the month, there is never more than one day of difference between the start of the first zodiac period considered and the start of the zodiac period immediately. next. More precisely, from March to May, the periods of the zodiac concerned, at namely ram, bull and gemini, all start on the 21st of the month. The next zodiac period, that of cancer, begins on June 22. From July to November, the corresponding zodiac periods, namely Leo, Virgo, Libra, Scorpio and Sagittarius, all start on the 23rd of the month. In December, the Capricorn period begins on the 22nd, in January, the Aquarius period begins on the 21st, and in February, the Fish period begins on the 20th.

Comme on le comprendra mieux par la suite, le profil de la came de gestion 8 est agencé de façon que l'organe indicateur 2 change de période zodiacale le premier jour de la période zodiacale considérée. Ainsi, le profil de la came de gestion 8 présente un premier rayon R1 qui va permettre, via le marteau 26 et la bascule 24, à l'organe indicateur 2 de changer de période zodiacale dans la nuit du 22 au 23 des mois de juillet, août, septembre, octobre et novembre. De même, le profil de la came de gestion 8 présente un deuxième rayon R2 différent du premier rayon R1 qui va permettre à l'organe indicateur 2 de changer de période zodiacale dans la nuit du 21 au 22 des mois de juin et décembre. De même, le profil de la came de gestion 8 présente un troisième rayon R3, différent des premier et deuxième rayons R1 et R2, qui va permettre à l'organe indicateur 2 de changer de période zodiacale dans la nuit du 20 au 21 des mois de janvier, mars, avril et mai. Enfin, le profil de la came de gestion 8 présente un quatrième rayon R4, différent des rayons R1, R2 et R3, qui va permettre à l'organe indicateur 2 de changer de période zodiacale dans la nuit du 19 au 20 du mois de février. Ainsi, le profil de la came de gestion 8 présente une première portion de rayon R1 constant pour les mois de juillet, août, septembre, octobre et novembre, puis une deuxième portion de rayon R2 pour le mois de décembre, puis une troisième portion de rayon R3 pour le mois de janvier, puis une quatrième portion de rayon R4 pour le mois de février, puis une cinquième portion de rayon R3 constant pour les mois de mars, avril et mai, et enfin une sixième et dernière portion de rayon R2 correspondant au mois de juin.As will be better understood below, the profile of the management cam 8 is arranged so that the indicator member 2 changes from zodiac period on the first day of the zodiac period considered. Thus, the profile of the management cam 8 has a first radius R1 which will allow, via the hammer 26 and the rocker 24, the indicator member 2 to change the zodiac period during the night of July 22 to 23 , August, September, October and November. Similarly, the profile of the management cam 8 has a second radius R2 different from the first radius R1 which will allow the indicator member 2 to change the zodiac period during the night of 21 to 22 June and December. Similarly, the profile of the management cam 8 has a third radius R3, different from the first and second rays R1 and R2, which will allow the indicator member 2 to change the zodiac period during the night of 20 to 21 months January, March, April and May. Finally, the profile of the management cam 8 has a fourth radius R4, different from the rays R1, R2 and R3, which will allow the indicator member 2 to change the zodiac period during the night of 19 to 20 February . Thus, the profile of the management cam 8 has a first portion of radius R1 constant for the months of July, August, September, October and November, then a second portion of radius R2 for the month of December, then a third portion of radius R3 for the month of January, then a fourth portion of radius R4 for the month of February, then a fifth portion of radius R3 constant for the months of March, April and May, and finally a sixth and last portion of radius R2 corresponding in the month of June.

A titre d'exemple, pour la période du 21 janvier au 19 février, l'organe indicateur 2 affiche la période zodiacale du verseau (voir figures 5 et 6). Dans la situation illustrée à la figure 6 dans laquelle se trouve le dispositif d'affichage 1 selon l'invention le 16 février, la bascule 24 est pré-positionnée de façon à permettre à l'organe indicateur 2 de passer de la période zodiacale du verseau à la période zodiacale du poisson dans la nuit du 19 au 20 février. A la fin du mois de février, le doigt entraîneur de mois 20 fait avancer d'un pas la roue indicatrice de mois 22 sur laquelle est fixée la came de gestion 8 de la durée d'affichage des évènements périodiques. Sous l'effet du pivotement de la came de gestion 8, le bec palpeur 28 du marteau 26 va passer de la quatrième portion de rayon R4 du profil de la came de gestion 8 à la cinquième portion de rayon R3 du profil de la came de gestion 8. Ce changement de rayon de courbure du profil de la came de gestion 8 va être transmis, via le bec palpeur 28 du marteau 26, à la bascule 24 qui est maintenue en appui élastique contre le marteau 26 grâce au ressort de rappel 30.For example, for the period from January 21 to February 19, the indicator organ 2 displays the zodiac period of Aquarius (see figures 5 and 6 ). In the situation illustrated in figure 6 in which is located the display device 1 according to the invention on February 16, the flip-flop 24 is pre-positioned so as to allow the indicator member 2 to pass from the zodiac period of the aquarius to the zodiac period of the fish in the night of February 19-20. At the end of February, the month driving finger 20 advances by one step the month indicator wheel 22 on which is fixed the management cam 8 of the duration of display of the periodic events. Under the effect of the pivoting of the management cam 8, the feeler beak 28 of the hammer 26 will pass from the fourth portion of radius R4 of the profile of the management cam 8 to the fifth portion of radius R3 of the profile of the cam management 8. This change in the radius of curvature of the profile of the management cam 8 will be transmitted, via the feeler spout 28 of the hammer 26, to the rocker 24 which is held in elastic support against the hammer 26 by means of the return spring 30 .

Le changement de rayon de courbure du profil de la came de gestion 8 va commander le pivotement de la bascule 24 autour d'un centre de rotation O (voir figures 5 et 7) Sous l'effet de ce pivotement, une roue satellite 32, montée folle en extrémité de la bascule 24, tourne sur elle-même et autour du centre de rotation O. Au cours de ce mouvement, la roue satellite 32 roule sur une denture d'une roue solaire 34 qui reste fixe. Cette roue solaire 34 est montée rotative autour du centre de rotation O de la bascule 24, concentriquement à la roue indicatrice de quantième 18. Une fois que le changement de rayon de courbure du profil de la came de gestion 8 s'est produit à la fin du mois de février et que la bascule 24 a pivoté en conséquence, celle-ci reste à nouveau immobile jusqu'à la fin du mois de mars et le dispositif d'affichage 1 selon l'invention est pré-positionné pour permettre à l'organe indicateur 2 de passer de la période zodiacale du poisson à la période zodiacale du bélier dans la nuit du 20 au 21 mars.The change in the radius of curvature of the profile of the management cam 8 will control the pivoting of the rocker 24 around a center of rotation O (see figures 5 and 7 ) Under the effect of this pivoting, a satellite wheel 32, mounted madly at the end of the rocker 24, rotates on itself and around the center of rotation O. During this movement, the satellite wheel 32 rolls on a toothing of a solar wheel 34 which remains fixed. This solar wheel 34 is rotatably mounted around the center of rotation O of the lever 24, concentrically with the date indicator wheel 18. Once the change in the radius of curvature of the profile of the management cam 8 has occurred at the end of February and that the rocker 24 has pivoted accordingly, it remains stationary again until the end of March and the display device 1 according to the invention is pre-positioned to allow the indicator 2 to pass from the zodiac period of the fish to the zodiac period of the ram on the night of March 20 to 21.

Lors du changement de rayon de courbure du profil de la came de gestion 8 au moment du passage de la fin du mois de février au premier jour du mois de mars, la bascule 24 adopte une nouvelle position qui va ensuite permettre à l'organe indicateur 2 de passer de l'indication de la période zodiacale du poisson à l'indication de la période zodiacale du bélier peu de temps avant minuit durant la nuit du 20 au 21 mars. Plus précisément, durant la période qui sépare la fin du mois de février jusqu'au 20 mars suivant, la roue entraîneuse de quantième 14 tourne à raison d'un tour par jour et fait avancer la roue indicatrice de quantième 18 d'un pas par jour. Le doigt entraîneur de mois 20 avance de conserve avec la roue indicatrice de quantième 18. Contrôlée par la came de gestion 8, la position de la bascule 24 est telle que, lors du passage du 20ème au 21ème jour du mois de mars, le doigt entraîneur de mois 20 entraîne en rotation la roue satellite 32 (voir figure 8). Comme la bascule 24 est maintenue par son ressort de rappel 30 en appui contre le marteau 26, elle ne peut pivoter, de sorte que la roue satellite 32 entraîne la roue solaire 34 en rotation. A son tour, la roue solaire 34 fait avancer d'un pas une roue indicatrice de zodiaque 36 qui porte les indications des douze signes du zodiaque et dont la position est indexée par un sautoir 38. Ainsi, l'indication du zodiaque passe du poisson au bélier.When changing the radius of curvature of the profile of the management cam 8 at the time of the transition from the end of February to the first day of March, the lever 24 adopts a new position which will then allow the indicating member 2 to pass from the indication of the zodiac period of the fish to the indication of the zodiac period of the ram shortly before midnight during the night of March 20 to 21. More specifically, during the period between the end of February and the following March 20, the date driving wheel 14 rotates at the rate of one revolution per day and advances the date indicator wheel 18 by one step. day. The 20 months advance canned coach finger with the calendar indicator wheel 18. Controlled by the Management cam 8, the position of the lever 24 is such that, during the passage of the 20 th to 21 th day of March, the month driving finger 20 rotates the satellite wheel 32 (see figure 8 ). As the lever 24 is held by its return spring 30 bearing against the hammer 26, it cannot pivot, so that the satellite wheel 32 drives the sun wheel 34 in rotation. In turn, the solar wheel 34 advances by one step a zodiac indicator wheel 36 which carries the indications of the twelve signs of the zodiac and whose position is indexed by a jumper 38. Thus, the indication of the zodiac passes from the fish to the ram.

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. En particulier, on comprendra que, bien que la présente invention ait été décrite en liaison avec l'affichage des douze périodes du zodiaque, cette invention n'est pas limitée à un tel mode de réalisation et peut être appliquée à l'affichage d'autres évènements périodiques formant un cycle annuel. On pense notamment à l'affichage de l'horoscope chinois. On notera également que, tous les 31 du mois, le doigt entraîneur de mois entraîne la roue indicatrice de mois et que, une fois par mois, le jour du changement de période du zodiaque, le doigt entraîneur de mois entraîne la roue satellite qui elle-même entraîne la roue indicatrice de zodiaque via la roue solaire. On comprendra aussi qu'à la fin des mois de moins de 31 jours, il est nécessaire de faire avancer le mécanisme de quantième jusqu'au quantième « 1 » afin de garantir que le dispositif d'affichage selon l'invention demeure convenablement indexé par rapport au calendrier.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. In particular, it will be understood that, although the present invention has been described in connection with the display of the twelve periods of the zodiac, this invention is not limited to such an embodiment and can be applied to the display of other periodic events forming an annual cycle. We are thinking in particular of the display of the Chinese horoscope. It will also be noted that, every 31st of the month, the month driving finger drives the month indicator wheel and that, once a month, on the day of the change of zodiac period, the month driving finger drives the satellite wheel which it -even drives the zodiac indicator wheel via the sun wheel. It will also be understood that at the end of the months of less than 31 days, it is necessary to advance the date mechanism to the date "1" in order to guarantee that the display device according to the invention remains suitably indexed by schedule report.
