Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine de l'horlogerie. Elle concerne, plus particulièrement, un mécanisme d'affichage d'un évènement périodique tel que les phases de la lune ou une indication de quantième.The present invention relates to the field of watchmaking. More particularly, it relates to a mechanism for displaying a periodic event such as the phases of the moon or a date indication.

L'invention concerne également une pièce d'horlogerie comportant un tel mécanisme d'affichage d'un évènement périodique.The invention also relates to a timepiece comprising such a mechanism for displaying a periodic event.

Etat de la techniqueState of the art

Les horloges astronomiques et montres à quantièmes sont bien connues depuis respectivement les 16eme et 17eme siècles et de nombreux mécanismes destinés à l'affichage des évènements calendaires périodiques ont été proposés dans l'état de la technique. Les plus communs dans les montres bracelets sont les quantièmes simple ou perpétuels, ainsi que les phases de la lune. De manière générale et simplifiée, ces différents mécanismes comportent un rouage de quantième ou de lunaison comportant une roue étoile dont le nombre de dents (7 pour le semainier, 12 pour les mois, 31 pour les jours, 59 pour les lunes, etc..) est agencé en liaison cinématique d'une part avec le mobile des heures du rouage de finissage d'un mouvement horloger, un indicateur de quantième ou de phases de lune à disque ou étoile étant solidaire en rotation de la roue étoile. Le rouage est conçu pour faire faire un pas par jour à la roue étoile pour suivre l'évolution calendaire normale et afficher les informations correspondantes sur ou dans le cadran de la montre.Astronomical clocks and date watches are well known since the 16th and 17th centuries, respectively, and many mechanisms for displaying periodic calendar events have been proposed in the state of the art. The most common in wristwatches are simple or perpetual calendars, as well as the phases of the moon. In a general and simplified manner, these various mechanisms include a date or lunar wheel having a star wheel whose number of teeth (7 for the week, 12 for the month, 31 for the days, 59 for the moons, etc. .. ) is arranged kinematically on the one hand with the mobile hours of the finishing gear of a watch movement, a date indicator or disc or star moon phase being integral in rotation with the star wheel. The gear train is designed to take the star wheel one step per day to follow the normal calendar evolution and display the corresponding information on or in the watch face.

On connait également certains mécanismes de ce type conçus pour procurer un affichage rétrograde, comme par exemple décrit dans les brevets CH 703 546 B1 ou encore CH 701 836 B1 . Ces mécanismes requièrent cependant pour opérer les sauts de retour de l'aiguille rétrograde l'utilisation de cames de formes complexes associées à des râteaux en liaison cinématique avec l'aiguille rétrograde, le tout dans un encombrement réduit, pour ne pas affecter les autres fonctions du mouvement horloger, ce qui rend leur réalisation et leur mise en oeuvre ardue, avec souvent des précisions d'affichage assez sommaires.Also known are certain mechanisms of this type designed to provide a retrograde display, as for example described in the patents CH 703 546 B1 or CH 701 836 B1 . These mechanisms require, however, to operate the return jumps of the retrograde needle the use of cams of complex shapes associated with rakes in kinematic connection with the retrograde needle, all in a small footprint, so as not to affect the other functions the watch movement, which makes their realization and their implementation difficult, with often rather brief display precisions.

La présente invention a pour but de proposer un mécanisme d'affichage rétrograde d'un évènement périodique qui soit plus simple à réaliser, plus fiable dans son fonctionnement et plus précis que les mécanismes connus de l'art antérieur.The object of the present invention is to provide a retrograde display mechanism for a periodic event that is simpler to perform, more reliable in its operation and more accurate than the mechanisms known from the prior art.

Quelque que soit le cas cependant, l'organe suiveur est maintenu en appui permanent dans le chemin de came par un ressort.Whatever the case, however, the follower member is maintained in permanent support in the cam path by a spring.

Selon une forme de réalisation, la première partie du cadran est circulaire et concentrique à la deuxième partie du cadran.According to one embodiment, the first part of the dial is circular and concentric with the second part of the dial.

Selon une forme de réalisation, l'évènement périodique est une phase de la lune, ledit index représentant les différentes phases de la lune sur une lunaison de 29,53 jours et le chemin de came étant configuré de telle sorte que l'organe indicateur indique suive en continu les représentations des phases consécutives d'une lunaison et revienne à une position dite de « nouvelle lune » à la fin d'une lunaison.According to one embodiment, the periodic event is a phase of the moon, said index representing the different phases of the moon on a lunation of 29.53 days and the cam path being configured so that the indicator organ indicates follow the representations of the consecutive phases of a lunation continuously and return to a so-called "new moon" position at the end of a lunation.

Mode de réalisation de l'inventionEmbodiment of the invention

On a représenté sur les figures 1 et 2, un mode de réalisation d'un mécanisme d'affichage d'un évènement périodique, et plus particulièrement dans l'exemple précis de phases de la lune, selon l'invention. Un tel mécanisme d'affichage est en particulier destiné à être monté dans une pièce d'horlogerie telle qu'une montre, en liaison cinématique avec un mouvement horloger, notamment un mouvement mécanique, de la pièce d'horlogerie, tous deux non représentés sur les figures.We have shown on figures 1 and 2 , an embodiment of a mechanism for displaying a periodic event, and more particularly in the specific example of phases of the moon, according to the invention. Such a display mechanism is in particular intended to be mounted in a timepiece such as a watch, in kinematic connection with a watch movement, in particular a mechanical movement, of the timepiece, both not shown on the figures.

Ce mécanisme comporte en premier lieu, comme représenté sur la figure 1, un cadran d'affichage C de pièce d'horlogerie telle qu'une montre en vue de dessus, sur laquelle les éléments apparents du mécanisme d'affichage de l'invention sont visibles. Ces éléments comportent en particulier dans l'exemple représenté une première partie de cadran C1, de forme sensiblement circulaire, et une seconde partie de cadran C2, en forme d'anneau disposé de manière concentrique et coplanaire à la première partie C1. Chacune des parties C1, C2 du cadran C présente une face supérieure dite d'affichage et une face inférieure dite de rouage. L'anneau de cadran C2 est avantageusement agencé mobile en rotation autour de la première partie C1 par l'intermédiaire d'un rouage d'affichage R, représenté sur la figure 2, assurant une liaison cinématique de l'anneau C2, doté d'une couronne dentée interne 1, formée ou fixée sur la face de rouage de l'anneau C2 du cadran. avec la roue des heures 3 du rouage de finissage d'un mouvement horloger via un pignon 2 chassé sur l'axe de rotation de la roue des heures 3.This mechanism comprises in the first place, as shown in figure 1 , a timepiece display dial C such as a watch in top view, on which the visible elements of the display mechanism of the invention are visible. These elements comprise in particular in the example shown a first portion of dial C1, of substantially circular shape, and a second dial portion C2, ring-shaped disposed concentrically and coplanar with the first part C1. Each of the parts C1, C2 of the dial C has a so-called upper display face and a so-called lower wheel face. The dial ring C2 is advantageously arranged mobile in rotation around the first part C1 by means of a display gear R, shown in FIG. figure 2 , providing a kinematic connection of the ring C2, provided with an internal ring gear 1, formed or fixed on the gear face of the ring C2 of the dial. with the hour wheel 3 of the finishing gear of a watch movement via a pinion 2 driven on the axis of rotation of the hour wheel 3.

La première partie C1 du cadran C comporte sur sa face d'affichage un index de lune principal 14 représentatif d'un évènement périodique à afficher, en l'espèce des phases de la lune sur une lunaison complète. Dans le mode de réalisation représenté, ledit index de lune principal 14 comporte une piste circulaire 14a indiquant les jours sur une phase croissante d'une lunaison depuis une position « 0 », dite de « nouvelle lune » jusqu'à une position dite de pleine lune, indiquée par un chiffre 14, associée à une échelle graduée 14b représentative de l'évolution de la luminosité de la lune sur cette phase croissante, ladite échelle graduée 14b étant composée de segments de longueurs croissante et progressives dont le plus grand est agencé en regard du secteur de piste 14a correspondant au quatorzième jour de lunaison. Un organe indicateur, constitué d'une aiguille dite de lune 8, est associé à l'index de lune principal 14 afin d'indiquer progressivement à la manière d'une indication de quantième horaire classique sur quel jour de la lunaison on se trouve. Cette aiguille de lune 8 est montée mobile en rotation par rapport à la partie fixe du cadran C1 de manière à pouvoir pivoter sur son axe au-dessus du cadran C ou, le cas échéant en dessous de celui-ci, notamment si la partie fixe C1 dudit cadran C est transparente. Ladite aiguille de lune 8 est en outre agencée en liaison cinématique (fig. 2) avec le rouage d'affichage R par l'intermédiaire d'un pignon 9 sur lequel l'aiguille est fixée (en l'espèce vissée) et d'un organe suiveur de came 7 muni d'une crémaillère engrenant le pignon 9 et agencé mobile en translation dans une lumière radiale 17 formée dans la partie C1 du cadran C.The first part C1 of the dial C has on its display face a main moon index 14 representative of a periodic event to display, in this case phases of the moon on a complete lunar. In the embodiment shown, said main moon index 14 comprises a circular track 14a indicating the days on a growing phase of a lunation from a position "0", called "new moon" to a so-called full position. moon, indicated by a number 14, associated with a scale 14b representative of the evolution of the brightness of the moon on this increasing phase, said scale 14b being composed of segments of increasing lengths and progressive, the largest is arranged next to the track section 14a corresponding to the fourteenth day of lunation. An indicator organ, consisting of a so-called moon hand 8, is associated with the main moon index 14 in order to indicate progressively in the manner of an indication of a standard calendar date on which day of the lunation one is. This moon hand 8 is rotatably mounted relative to the fixed part of the dial C1 so as to be pivotable on its axis above the dial C or, if necessary below it, especially if the fixed part C1 of said dial C is transparent. Said moon hand 8 is further arranged in kinematic connection ( Fig. 2 ) with the display gear R via a pinion 9 on which the needle is fixed (in this case screwed) and a cam follower member 7 provided with a rack meshing with the pinion 9 and arranged movable in translation in a radial slot 17 formed in the part C1 of the dial C.

L'organe suiveur de came 7 prend avantageusement appui en butée au niveau d'une extrémité de contact 71 sur un chemin de came 13 formée sur la face d'affichage de l'anneau mobile C2 du cadran C. Ledit chemin de came 13 est avantageusement constitué de n sections 13s identiques et consécutives, en l'espèce de douze sections 13s composées chacune de deux segments de cames 13a, 13b successifs et consécutifs tels que l'extrémité de contact 71 du suiveur de came 7 glisse parcourt l'intégralité d'une section 13s sur une lunaison complète, et donc parcourt un dit segment de came 13a, 13b sur une durée égale à une demi-lunaison lors de la rotation de l'anneau C2 du cadran C sous l'effet du rouage d'affichage R via sa couronne dentée 1 comme il sera décrit par la suite. Bien entendu, le nombre de sections 13s du chemin de came 13 est déterminé par l'évènement périodique à afficher par le mécanisme d'affichage de l'invention. Dans le cas d'espèce, 12 sections 13s permettent d'afficher les 12 lunaisons complètes d'une année civile de 12 mois.The follower cam member 7 advantageously abuts at a contact end 71 on a cam path 13 formed on the display face of the movable ring C2 of the dial C. Said cam path 13 is advantageously consisting of n identical and consecutive sections 13s, in this case twelve sections 13s each composed of two successive and consecutive cam segments 13a, 13b such that the contact end 71 of the cam follower 7 slides runs through the entire a section 13s on a complete lunation, and thus traverses a said cam segment 13a, 13b for a duration equal to half a lunation during the rotation of the ring C2 of the dial C under the effect of the display gear R via its ring gear 1 as will be described later. Of course, the number of sections 13s of the cam path 13 is determined by the periodic event to be displayed by the display mechanism of the invention. In the present case, 12 sections 13s make it possible to display the 12 complete lunations of a calendar year of 12 months.

Le chemin de came 13 est de préférence constitué d'une paroi saillante ou d'une coulisse creusée dans la face d'affichage de la seconde partie C2 du cadran, notamment par exemple par déformation plastique, moulage, dépôt, retrait de matière, assemblage ou usinage de la seconde partie C2 du cadran C.The cam path 13 is preferably constituted by a protruding wall or a slide dug in the display face of the second part C2 of the dial, for example by plastic deformation, molding, deposition, removal of material, assembly or machining of the second portion C2 of the dial C.

L'aiguille de lune 8 est avantageusement mue en rotation vis-à-vis de l'index de lune principal 14 suivant un mouvement de rotation rétrograde, parcourant sur une première demi-lunaison l'intégralité de la piste 14a de l'index de lune principal 14 dans un sens alors que l'extrémité de contact 71 du suiveur de came 7 glisse sur un premier segment de came 13a, 13b, puis sur la demi-lunaison suivante faisant le parcourt inverse dans l'autre sens alors que le suiveur de came 7 glisse sur l'autre secteur de came 13b, 13a respectivement.The moon hand 8 is advantageously rotated with respect to the main moon index 14 in a retrograde rotational movement, traversing on a first half-moon the entire track 14a of the index finger. the main moon 14 in one direction while the contact end 71 of the cam follower 7 slides on a first cam segment 13a, 13b, then on the next half-lunation making the reverse flow in the other direction while the follower cam 7 slides on the other cam sector 13b, 13a respectively.

Afin de conférer son mouvement rétrograde à l'aiguille 8 en regard de l'index 14, le chemin de came 13 est avantageusement configuré dans l'exemple de réalisation présenté pour que le glissement de l'extrémité de contact 71 du suiveur de came 7 sur le un segment 13b du chemin de came 13 induise un mouvement de translation senestre du suiveur de came 7 dans la lumière 17 et un glissement sur un segment 13a un mouvement de translation dextre, respectivement un mouvement de rotation horaire et un mouvement de rotation antihoraire de l'aiguille 8 vis-à-vis de l'index 14. Aussi les segments 13a, 13b sont orientés l'un par rapport à l'autre successivement pour former le chemin de came 13 sur toute la surface supérieure de l'anneau C2 suivant un angle α obtus ouvert vers le centre du cadran C compris entre 110° et 135°, conférant ainsi au chemin de came 13 une forme dentelée.In order to impart its retrograde movement to the needle 8 facing the index 14, the cam path 13 is advantageously configured in the embodiment shown for the sliding of the contact end 71 of the cam follower 7 on a segment 13b of the cam path 13 induces a sinister translation movement of the cam follower 7 in the lumen 17 and a sliding on a segment 13a a dextral translation movement, respectively a clockwise rotational movement and a counterclockwise rotational movement of the needle 8 vis-à-vis the index 14. Also the segments 13a, 13b are oriented relative to each other successively to form the cam path 13 on the entire upper surface of the ring C2 at an obtuse angle α open towards the center of the dial C between 110 ° and 135 °, thus conferring on the cam path 13 a serrated shape.

Afin d'assister le mouvement de translation senestre du suiveur de came 7 et de l'aiguille 8 dans le sens antihoraire un ressort lame 10 est avantageusement agencé solidaire à une première extrémité du pignon 9 portant l'aiguille 8 et fixé à une seconde extrémité sur la partie fixe C1 du cadran C, ou en variante sur une platine du mouvement horloger associé au dispositif d'affichage de l'invention.In order to assist the sinister translation movement of the cam follower 7 and the needle 8 counterclockwise a leaf spring 10 is advantageously arranged integral with a first end of the pinion 9 carrying the needle 8 and fixed at a second end. on the fixed part C1 of the dial C, or alternatively on a platen of the watch movement associated with the display device of the invention.

En complément de l'index de lune principal 14 des jours et intensité lumineuse d'une lunaison le mécanisme d'affichage de l'invention comporte également un index secondaire 15 d'indication du caractère croissant ou décroissant de la lune. Cet index secondaire 15 comporte simplement deux secteurs 15a, 15b contigus portant respectivement un signe « + » et un signe « - » et de longueur égale disposés sur un rebord de la partie fixe C1 du cadran C tel que le milieu 15m des deux secteurs 15a, 15b soit alignés radialement avec un curseur de lune 18 sur l'anneau C2 mobile du cadran C lorsque, comme représenté sur la figure 1, l'extrémité de contact 71 du suiveur de came 7 est localisée dans l'angle α entre deux segments 13a, 13b du chemin de came 13, l'aiguille 8 étant alors face à la graduation « 14 », c'est-à-dire à mi-lunaison et pleine lune. EN pratique, l'anneau C2 porte 12 curseurs de lune 18 répartis régulièrement sur la périphérieIn addition to the main moon index 14 of the days and luminous intensity of a lunation, the display mechanism of the invention also includes a secondary index 15 for indicating the increasing or decreasing nature of the moon. This secondary index 15 simply comprises two contiguous sectors 15a, 15b bearing respectively a sign "+" and a sign "-" and of equal length arranged on a flange of the fixed part C1 of the dial C such that the middle 15m of the two sectors 15a, 15b is aligned radially with a moon slider 18 on the mobile ring C2 of the dial C when, as shown in FIG. figure 1 , the contact end 71 of the cam follower 7 is located in the angle α between two segments 13a, 13b of the cam path 13, the needle 8 then facing the graduation "14", that is to say say mid-moon and full moon. In practice, the ring C2 carries 12 moon sliders 18 regularly distributed on the periphery

Le cadran C du mécanisme d'affichage de l'invention comporte enfin dans l'exemple représenté, mais de façon accessoire et non essentielle au mécanisme d'affichage de l'invention un cadran secondaire 16 d'affichage de l'heure situé à 12h et au-dessus du cadran principal C, ce cadran d'affichage secondaire 16 étant associé à des aiguilles de heures et minutes respectivement chassées sur un canon solidaire de la roue de heures 3 (fig.2) et sur la chaussée coaxiale au canon de de l'aiguille des heures de manière classique en soit.The dial C of the display mechanism of the invention finally comprises in the example shown, but in an accessory and non-essential manner to the display mechanism of the invention, a secondary dial 16 for displaying the time at 12 o'clock and above the main dial C, this secondary display dial 16 being associated with hour and minute hands respectively driven on a gun secured to the hour wheel 3 ( fig.2 ) and on the coaxial roadway to the barrel of the hour hand conventionally in itself.

La figure 2 représente en détail la constitution du rouage d'affichage R du mécanisme d'affichage de l'invention permettant de réaliser la liaison cinématique entre la roue des heures 2 d'un mouvement horloger et l'anneau C2 du cadran d'affichage C du mécanisme d'affichage, qui porte le chemin de came 13 actionnant via le suiveur de came le déplacement de l'aiguille 8 vis-à-vis de l'index 14 et déplaçant le curseur 18 en regard de l'index secondaire 15 pour indiquer la nature croissante ou décroissante de la lune sur une demi-lunaison indiquée par l'index 14 et l'aiguille 8.The figure 2 shows in detail the constitution of the display gear R of the display mechanism of the invention for making the kinematic connection between the hour wheel 2 of a watch movement and the ring C2 of the display dial C of the mechanism display, which carries the cam path 13 actuating via the cam follower the displacement of the needle 8 vis-à-vis the index 14 and moving the slider 18 opposite the secondary index 15 to indicate the increasing or decreasing nature of the moon on half a lunation indicated by the index 14 and the needle 8.

Ce rouage d'affichage R, ou rouage de lune, comporte ainsi, depuis la roue des heures 3 :

  • un pignon des heures 2, coaxial à la roue des heures 3, et comportant une denture z1 de 24 dents,
  • une première roue de lune 4, dite à friction, comportant une denture périphérique z2 de 62 dents,
  • un premier pignon de lune 5 coaxial à la première roue de lune à friction, ledit premier pignon comportant une denture z3 de 16 dents,
  • une première roue de renvoi 6,
  • une deuxième roue de lune 12 comportant une denture périphérique z4 de 93 dents,
  • un second pignon de lune 11 porté par la deuxième roue de lune 12 et comportant une denture z5 de 10 dents et engrenant avec,
  • un anneau de lune C2, formant comme précédemment indiqué une partie périphérique du cadran C, et comportant une couronne dentée intérieure 1 comportant une denture z6 de 236 dents.
This display wheel R, or moon gear, thus comprises, since the hour wheel 3:
  • a pinion hours 2, coaxial with the hour wheel 3, and having a tooth z1 of 24 teeth,
  • a first moon wheel 4, called friction wheel, having a peripheral toothing Z2 of 62 teeth,
  • a first moon gear 5 coaxial with the first friction moon gear, said first gear having a tooth of z3 of 16 teeth,
  • a first return wheel 6,
  • a second moon wheel 12 having a peripheral tooth z4 of 93 teeth,
  • a second moon gear 11 carried by the second moon wheel 12 and having a toothing z5 of 10 teeth and meshing with,
  • a moon ring C2, forming as previously indicated a peripheral portion of the dial C, and having an inner ring gear 1 having a tooth z6 236 teeth.

Le rouage d'affichage de lune R est ainsi agencé tel que la première roue de lune 4 engrène par sa denture z2 la denture z1 du pignon des heures 2 d'une part et le premier pignon de lune 5 engrène par sa denture z3 avec la première roue de renvoi 6, qui elle-même engrène avec la 2nd roue de lune 12 agencée en liaison cinématique par le pignon de lune 11 avec l'anneau de lune C2 via la couronne dentée 1. Cette chaine cinématique permet ainsi de d'entrainer avec une démultiplication idoine l'anneau C2 en rotation dans un sens antihoraire depuis la roue des heures 3, cette rotation permettant par le biais du chemin de came 13 sur lequel le suiveur de came 7 prend appui de déplacer l'aiguille de lune 8, accouplée par son pignon 9 à la crémaillère du suiveur de came 7, vis-à-vis de l'index principal de lune 14.The moon display gear train R is thus arranged such that the first moon gear 4 engages, by its toothing z2, the toothing z1 of the hour gear 2 on the one hand and the first moon gear 5 meshes by its toothing z3 with the first deflection wheel 6, which itself meshes with the 2 nd moon wheel 12 arranged in kinematic connection by the moon gear 11 with the moon ring C2 via the ring gear 1. This kinematic chain thus allows d ' train with appropriate gearing the ring C2 in rotation in a counterclockwise direction from the hour wheel 3, this rotation allowing through the cam path 13 on which the cam follower 7 is supported to move the moon hand 8 , coupled by its pinion 9 to the rack of the cam follower 7, vis-à-vis the main moon index 14.

Le mécanisme d'affichage de la présente invention procure ainsi de manière avantageuse un affichage de phases de la lune original avec une aiguille animée d'un mouvement rétrograde, sans représentation visuelle schématique de la lune, comme proposé par une immense majorité d'affichages de phases de lune de l'art antérieur. Il ne requiert en outre aucun disque de lune, et utilise une partie mobile de cadran C2 en guise de came d'actionnement de l'aiguille de lune 8, ce qui procure une simplification du mécanisme d'affichage, ainsi qu'une double animation dans le cadran par déplacement de l'anneau C2 autour de la partie centrale fixe C1 qui engendre le déplacement de l'aiguille de lune 8 vis-à-vis de l'index de lune principal 14 et des curseurs de lune 18 vis-à-vis de l'index secondaire 15.The display mechanism of the present invention thus advantageously provides a phase display of the original moon with a retrograde motion-driven hand, without a schematic visual representation of the moon, as proposed by a vast majority of display views. moon phases of the prior art. It also does not require any moon disk, and uses a moving part of the dial C2 as a cam for actuating the moon hand 8, which provides a simplification of the display mechanism, as well as a double animation in the dial by displacement of the ring C2 around the fixed central portion C1 which causes the displacement of the moon hand 8 vis-à-vis the main moon index 14 and the moon sliders 18 vis-à-vis of the secondary index 15.

Un autre avantage majeur du mécanisme d'affichage de l'invention est sa précision accrue en comparaison des mécanismes d'affichage de phases de lune connus, conféré notamment par la grande denture z6 de la couronne dentée 1 de l'anneau C2. En effet, le rapport de lunaison RL procuré pour une lunaison par le mécanisme de l'invention est calculé tel que : RL = z 6 × z 7 × z 2 12 × z 5 × z 3 × z 1 = 29.530729

Figure imgb0001
Another major advantage of the display mechanism of the invention is its increased accuracy in comparison with the known moon phase display mechanisms, conferred in particular by the large toothing z6 of the ring gear 1 of the ring C2. Indeed, the ratio of lunation RL procured for a lunation by the mechanism of the invention is calculated such that: RL = z 6 × z 7 × z 2 12 × z 5 × z 3 × z 1 = 29.530729
Figure imgb0001

Soit une précision de 29 jours, 12h, 44 minutes et 15 secondes. Aussi, en considérant les valeurs de révolution de la Terre et du Soleil convenue en 1961, un défaut de 1 jour sur l'affichage de lunaison sera constaté uniquement après 577 années. On peut donc considérer comme quasi-improbable la nécessité d'une correction de réglage du mécanisme de l'invention sur la durée de vie de la pièce d'horlogerie le comportant.That is an accuracy of 29 days, 12 hours, 44 minutes and 15 seconds. Also, considering the values of revolution of the Earth and the Sun agreed in 1961, a default of 1 day on the display of lunation will be noticed only after 577 years. It can therefore be considered almost improbable the need for a setting adjustment of the mechanism of the invention over the lifetime of the timepiece comprising it.

Le fonctionnement et le mode d'affichage et de lecture des phases de la lune selon le mécanisme d'affichage de l'invention sont représentés aux figures 3A-3C, les figures 4A-4D montrant des agrandissements des figures 3A-3C sur l'index secondaire 15.The operation and the mode of display and reading of the phases of the moon according to the display mechanism of the invention are represented in FIGS. Figures 3A-3C , the Figures 4A-4D showing enlargements of Figures 3A-3C on the secondary index 15.

La figure 3A représente l'affichage d'une lune croissante au 8eme jour de lunaison. L'extrémité de contact 71 du suiveur de came 7 et en appui sur un segment croissant 13b du chemin de came 13 sur l'anneau C2 du cadran, l'aiguille de lune se trouvant pointée sur le chiffre 8 de la piste 14a de l'index principal de lune 14. Le caractère croissant de la lune est alors indiqué par l'alignement radial d'un curseur 18 sur l'anneau C2 avec le secteur 15a portant l'indication « + » sur l'index secondaire 15.The figure 3A represents the display of a rising moon on the 8th day of lunation. The contact end 71 of the cam follower 7 and resting on a growing segment 13b of the cam path 13 on the ring C2 of the dial, the moon hand being pointed at the number 8 of the track 14a of the main moon index 14. The increasing character of the moon is then indicated by the radial alignment of a slider 18 on the ring C2 with the sector 15a marked "+" on the secondary index 15.

Depuis le 8eme jour de croissance jusqu'au 15eme jour, l'anneau C2 poursuit sa rotation dans le sens antihoraire de telle sorte que le suiveur de came 7 glisse sur le segment 13b du chemin de came jusqu'à atteindre une position d'équilibre entre ledit segment 13b et le secteur 13a consécutif, dans l'angle α, comme représenté sur la figure 3B. L'aiguille de lune 8 est alors en position sensiblement horizontale pointant vers l'extrémité supérieure de la piste 14a de l'index de lune principal 14, face à la graduation 14 et le segment de luminosité le plus grand. C'est donc la pleine lune, et le marqueur du milieu 15m de l'index secondaire 15 est alors aligné avec un curseur 18 sur l'anneau C2, comme représenté figure 4B.From the 8th day of growth to the 15th day, the ring C2 continues to rotate counterclockwise so that the cam follower 7 slides on the segment 13b of the cam path until reaching a position of equilibrium between said segment 13b and the consecutive sector 13a, in the angle α, as shown in FIG. figure 3B . The moon hand 8 is then in a substantially horizontal position pointing towards the upper end of the track 14a of the main moon index 14, facing the graduation 14 and the largest brightness segment. So it's the full moon, and the middle marker 15m of the secondary index 15 is then aligned with a cursor 18 on the ring C2, as shown Figure 4B .

La figure 3C représente enfin l'affichage d'une lune décroissante au 22eme jour de lunaison. L'aiguille de lune 8 est alors dans son mouvement rétrograde de retour vers le « 0 » de la piste 14a de l'index de lune principal 14. L'extrémité de contact 71 du suiveur de came 7 et en appui sur un segment décroissant 13a du chemin de came 13 sur l'anneau C2 du cadran, l'aiguille de lune se trouvant pointée sur le chiffre 8 de la piste 14a de l'index principal de lune 14. Le caractère décroissant de la lune est alors indiqué par l'alignement radial d'un curseur 18 sur l'anneau C2 avec le secteur 15b portant l'indication « - » sur l'index secondaire 15, comme représenté à la Fig. 4C.The figure 3C finally represents the display of a decreasing moon on the 22nd day of the lunation. The moon hand 8 is then in its retrograde movement back to the "0" of the track 14a of the main moon index 14. The contact end 71 of the cam follower 7 and resting on a descending segment 13a of the cam track 13 on the ring C2 of the dial, the moon hand being pointed at the number 8 of the track 14a of the main moon index 14. The decreasing character of the moon is then indicated by the radial alignment of a slider 18 on the ring C2 with the sector 15b bearing the indication "-" on the secondary index 15, as shown in FIG. Fig. 4C .

Le mécanisme d'affichage de l'invention permet ainsi par sa configuration une représentation simplifiée et animée d'un genre nouveau d'un évènement périodique tel que les phases de la lune comme précédemment décrit ou encore suivant un mécanisme analogue pour l'affichage de quantièmes. Il suffit pour cela en particulier de choisir une configuration de chemin de came 13, de ses sections 13s et/ou segments 13a, 13b de longueur et formes adaptés pour coopérer avec un ou des organes indicateurs appropriés pour renseigner l'évènement périodique souhaité, de même qu'en ajustant le rouage d'affichage le cas échéant.The display mechanism of the invention thus allows, by its configuration, a simplified and animated representation of a new kind of a periodic event such as the phases of the moon as previously described, or according to a similar mechanism for the display of calendars. It is sufficient for this purpose in particular to choose a cam path configuration 13, its sections 13s and / or segments 13a, 13b of length and shapes adapted to cooperate with one or more indicator organs suitable for informing the desired periodic event, of same as adjusting the display gear if necessary.

On peut notamment afficher, dans un exemple non représenté sur les figures, simultanément aux phases de lune un quantième annuel par exemple, par l'intermédiaire d'un disque de mois porté sur une étoile de quantième à 12 dents montée rotative sur la partie fixe du cadran C, un palpeur mobile en translation de manière analogue au suiveur de came 7 de l'aiguille de lune 8 étant agencé et rappelé par un ressort entre le chemin de came 13 et l'étoile de quantième de manière à faire pivoter ladite étoile d'un pas à chaque passage du palpeur d'une section 13s du chemin de came 13 à une section 13s consécutive. Le jour de quantième peut alors être affiché le cas échéant par une aiguille actionnée de manière sensiblement identique à l'aiguille de lune 8, ou un disque de quantième conformément aux mécanismes de quantième classiques de l'art antérieur.In an example not shown in the figures, it is possible to display, in an example not shown in the figures, simultaneously with the moon phases, an annual calendar, for example, by means of a month disk carried on a 12-tooth date star rotatably mounted on the fixed part. of the dial C, a probe movable in translation analogous to the cam follower 7 of the moon needle 8 is arranged and recalled by a spring between the cam path 13 and the date star so as to rotate said star one step at each passage of the probe from a section 13s of the cam path 13 to a section 13s consecutive. The date day can then be displayed if necessary by a needle actuated substantially identically to the moon hand 8, or a date disk in accordance with conventional date mechanisms of the prior art.

Bien entendu, des variations du mécanisme d'affichage de l'invention sont envisageables pour l'homme du métier, notamment en ce qui concerne la nature et la forme des organes indicateurs et des index associés pour donner l'information d'évènement périodique souhaitée.Of course, variations of the display mechanism of the invention are conceivable for those skilled in the art, particularly as regards the nature and the form of the indicator organs and associated indexes to give the desired periodic event information. .
