Description

PIECE D'HORLOGERIE MUNIE D'UN MECANISME D'AFFICHAGE DES  CLOCKWARE HAVING A DISPLAY MECHANISM
PHASES DE LUNE  PHASES OF MOON
La présente invention se rapporte à une pièce d'horlogerie munie d'un mécanisme d'affichage rétrograde des phases de lune comprenant un mobile indicateur des phases de lune en liaison cinématique avec une came entraînée par le rouage de minuterie, cette came étant conformée pour déplacer le mobile indicateur des phases de lune dans un sens durant la phase de lune ascendante et en sens inverse durant la phase de lune descendante, ce mobile indicateur étant monté vis-à-vis d'une échelle du cycle lunaire au moins en partie située sur un organe mobile monté déplaçable entre deux butées, l'organe mobile comportant un élément de mise en tension d'un sautoir et apte à venir en prise avec un élément d'entraînement solidaire dudit mobile indicateur aux deux extrémités du mouvement de ce mobile indicateur pour déplacer ledit organe mobile présentant l'échelle du cycle lunaire d'une butée à l'autre, le sautoir étant encore en prise avec cet organe mobile présentant les phases de lune pour le maintenir alternativement contre chacune desdites butées. The present invention relates to a timepiece provided with a retrograde moon phase display mechanism comprising a mobile moon phase indicator in kinematic connection with a cam driven by the timer train, this cam being shaped to moving the mobile indicator moon phases in one direction during the ascending moon phase and in the opposite direction during the descending moon phase, this mobile indicator being mounted vis-à-vis a scale of the lunar cycle at least partly located on a movable member movably mounted between two stops, the movable member comprising a tensioning element of a jumper and adapted to engage with a drive element secured to said mobile indicator at both ends of the movement of the mobile indicator for moving said movable member having the scale of the lunar cycle from one stop to the other, the jumper being still engaged with this movable member present the moon phases to maintain alternately against each of said stops.
On a déjà proposé un mécanisme indicateur des phases de lune à retour rétrograde de ce type dans le brevet européen EP 1 870 785.  A feedback phase moon phase indicator mechanism of this type has already been proposed in European Patent EP 1 870 785.
A la fin de chaque demi-cycle de lune, l'élément de mise sous tension permettant le basculement ou saut de l'organe mobile présentant l'échelle du cycle lunaire passe d'une face inclinée à l'autre du sautoir, ce qui a pour effet d'inverser le couple exercé par ce sautoir sous tension sur l'organe mobile présentant l'échelle du cycle lunaire, qui est de ce fait déplacé contre l'autre des deux butées. Ce basculement est réalisé en deux jours du fait du mouvement angulaire faible et lent de la came qui est transmis à l'élément de mise sous tension relié cinématiquement à la came. At the end of each half-moon cycle, the energizing element allowing the tilting or jumping of the mobile member having the scale of the lunar cycle passes from one inclined face to the other of the jumper, which has the effect of reversing the torque exerted by the jumper under tension on the movable member having the scale of the lunar cycle, which is thereby moved against the other of the two stops. This changeover is realized in two days because of the angular movement low and slow of the cam which is transmitted to the energizing element kinematically connected to the cam.
Le saut de l'organe mobile présentant l'échelle du cycle lunaire est réalisé en deux jours en raison du faible déplacement angulaire, ce qui n'est pas satisfaisant étant donné que l'on ne sait pas pendant deux jours si la phase de lune est croissante ou décroissante.  The jump of the mobile organ presenting the scale of the lunar cycle is realized in two days because of the weak angular displacement, which is not satisfactory since it is not known during two days if the phase of moon is increasing or decreasing.
Le but de la présente invention est de remédier, au moins en partie à cet inconvénient.  The object of the present invention is to remedy, at least in part, this disadvantage.
A cet effet, cette invention a pour objet une pièce d'horlogerie munie d'un mécanisme d'affichage des phases de lune selon la revendication 1.  For this purpose, this invention relates to a timepiece provided with a moon phase display mechanism according to claim 1.
L' invention est remarquable en ce que : le rapport entre ledit rouage de minuterie et ladite came est choisi pour faire un tour pendant deux cycles de lune, et en ce que la came est en forme de double cœur, chacun correspondant à un des cycles de lune, les épaulements des deux cœurs respectifs étant adjacents à un axe X-X' et leurs pointes respectives étant situées sur un axe perpendiculaire à l'axe X-X'.  The invention is remarkable in that: the ratio between said timer train and said cam is chosen to rotate for two moon cycles, and that the cam is in the form of a double core, each corresponding to one of the cycles of moon, the shoulders of the respective two cores being adjacent to an axis XX 'and their respective points being located on an axis perpendicular to the axis X-X'.
Cette nouvelle forme de la came permet d' augmenter la vitesse angulaire de l'élément de mise sous tension et donc raccourcit le saut de l'organe mobile présentant l'échelle du cycle lunaire. Par exemple, le saut est réalisé en un jour.  This new form of the cam makes it possible to increase the angular velocity of the energizing element and thus shortens the jump of the moving member presenting the scale of the lunar cycle. For example, the jump is made in one day.
Avantageusement, la came est une gorge dudit mobile intermédiaire dans laquelle un palpeur de came est engagé. Ceci permet d'obtenir une liaison desmodromique entre la came et l'organe mobile portant l'échelle du cycle lunaire contrairement à une liaison par simple appui élastique. Le choix d'une gorge répond à des contraintes cinématiques et dimensionnelles et offre de plus une sécurité en cas de choc.  Advantageously, the cam is a groove of said intermediate mobile in which a cam follower is engaged. This makes it possible to obtain a desmodromic connection between the cam and the mobile member carrying the scale of the lunar cycle, unlike a connection by simple elastic support. The choice of a groove responds to kinematic and dimensional constraints and offers more safety in case of shock.
D'autres avantages et particularités de la pièce d'horlogerie selon la présente invention apparaîtront au cours de la description qui suit, faite à l'aide des dessins annexés qui illustrent, schématiquement et à titre d'exemple, une forme d'exécution de la pièce d'horlogerie objet de cette invention. Other advantages and particularities of the timepiece according to the present invention will become apparent from the following description, made with the aid of the accompanying drawings. which illustrate, schematically and by way of example, an embodiment of the timepiece object of this invention.
La figure 1 est une vue de face de cette forme d' exécution montrant une première position des organes d'affichage; la figure 2 est une vue semblable à la figure 1 montrant une seconde position des organes d'affichage;  Figure 1 is a front view of this embodiment showing a first position of the display members; Figure 2 is a view similar to Figure 1 showing a second position of the display members;
la figure 3 est une vue du mécanisme d'affichage dans la position des organes d'affichage illustrée par la figure 1; la figure 4 est une vue du mécanisme d' affichage dans la position des organes d'affichage illustrée par la figure 2.  Figure 3 is a view of the display mechanism in the position of the display members shown in Figure 1; FIG. 4 is a view of the display mechanism in the position of the display members illustrated in FIG. 2.
Le mécanisme illustré par la figure 3 comporte un renvoi 1, en liaison cinématique avec le rouage de minuterie, seul mobile du rouage de minuterie représenté étant donné que c' est le seul qui sert à entraîner le rouage du mécanisme indicateur des phases de lune. Ce renvoi 1 effectue une rotation toutes les douze heures. Il engrène avec un mobile denté 2 présentant le double du nombre de dents du renvoi 1 pour ne faire qu'un tour en vingt-quatre heures. Ce mobile 2 porte un doigt d' entraînement 3 monté pivotant et maintenu de manière élastique contre et par un ressort 4.  The mechanism illustrated in Figure 3 comprises a reference 1, in kinematic connection with the timer train, the only mobile of the clockwork shown since it is the only one used to drive the gear moon phase indicator mechanism. This reference 1 rotates every twelve hours. It meshes with a toothed mobile 2 having twice the number of teeth of the reference 1 to make one turn in twenty-four hours. This mobile 2 carries a drive finger 3 pivotally mounted and resiliently held against and by a spring 4.
A chaque rotation du mobile 2, le doigt d'entraînement 3 rencontre une dent d'un mobile intermédiaire 5 à cinquante neuf dents positionné par un sautoir 6. Ce mobile intermédiaire 5 fait donc un tour en 59 jours correspondant approximativement à deux cycles de la lune avec une erreur d'un jour tous les 3 ans.  At each rotation of the mobile 2, the drive finger 3 encounters a tooth of an intermediate mobile 5 to fifty-nine teeth positioned by a jumper 6. This intermediate mobile 5 thus takes a turn in 59 days corresponding to approximately two cycles of the moon with an error of one day every 3 years.
Le mobile intermédiaire 5 présente une came en forme de double cœur 5a réalisée par une gorge dans le mobile 5. Le mobile intermédiaire 5 et la came 5a forment donc une seule et même pièce. Toutefois, en variante, il serait possible de solidariser une came rapportée sur le mobile intermédiaire 5. Chaque cœur correspond à un cycle de lune, les épaulements 5b des deux cœurs respectifs étant adjacents à un axe X-X' et leurs pointes 5d respectives étant situées sur un axe Y-Y' perpendiculaire à l'axe X-X'. Chaque cœur 5b présente de préférence un profil dissymétrique pour assurer la continuité du cycle . lunaire . The intermediate mobile 5 has a cam shaped double core 5a made by a groove in the mobile 5. The intermediate mobile 5 and the cam 5a thus form a single piece. However, alternatively, it would be possible to secure a cam attached to the intermediate mobile 5. Each core corresponds to a moon cycle, the shoulders 5b of the two respective cores being adjacent to an axis XX 'and their respective points 5d being located on an axis YY' perpendicular to the axis X-X '. Each core 5b preferably has an asymmetrical profile to ensure the continuity of the cycle. lunar.
Un palpeur de came 7 pivoté sur un axe comporte un galet ou un plot 7a et un secteur denté centré sur l'axe de pivotement et en prise avec un pignon 8 servant de mobile indicateur des phases de lune et dont l'axe est solidaire d'un index ou aiguille 15 (figures 1, 2) qui est déplacé en regard d'une échelle. Ce pignon 8 est encore en prise avec un second secteur denté 9 soumis à la force d'un ressort de rappel 10 qui sert à maintenir le plot 7a du palpeur de came 7 en contact avec le profil de la came 5a. Le pignon 8 est encore solidaire d'un plateau 8a auquel une cheville 8b est fixée .  A cam follower 7 pivoted on an axis comprises a roller or a stud 7a and a toothed sector centered on the pivot axis and in engagement with a pinion 8 serving as mobile indicator moon phases and whose axis is integral with an index or needle 15 (FIGS. 1, 2) which is moved opposite a ladder. This pinion 8 is still engaged with a second toothed sector 9 subjected to the force of a return spring 10 which serves to hold the stud 7a of the cam follower 7 in contact with the profile of the cam 5a. The pinion 8 is still secured to a plate 8a to which a pin 8b is fixed.
Le galet 7a en forme de demi-lune vient en contact avec la gorge 5a dans laquelle il est engagé et guidé. Le galet 7a est solidaire du palpeur de came présentant le secteur denté 7 qui engrène avec le mobile 8. Le galet 7a pourrait présenter d'autres formes.  The half-moon-shaped roller 7a comes into contact with the groove 5a in which it is engaged and guided. The roller 7a is integral with the cam follower having the toothed sector 7 which meshes with the mobile 8. The roller 7a could have other shapes.
Ainsi, l'axe X-X' définit le début et la fin des cycles de lune parcourus sur les deux cœurs dans la gorge 5a par le galet 7a du fait de la rotation du mobile intermédiaire 5 entraîné par le doigt d'entraînement 3, et l'axe Y-Y' définit les deux moitiés de cycles de lune parcourus sur les deux cœurs dans la gorge 5a par le galet 7a.  Thus, the axis XX 'defines the beginning and the end of the moon cycles traveled on the two cores in the groove 5a by the roller 7a due to the rotation of the intermediate wheel 5 driven by the driving finger 3, and the 'YY axis' defines the two halves of moon cycles traveled on the two hearts in the groove 5a by the roller 7a.
Un organe mobile 11, portant une échelle correspondant à l'indication des phases de lune d'un cycle lunaire, est monté pivotant sur l'axe du pignon 8 de l'indicateur des phases de lune. Cet organe mobile 11 est susceptible de pivoter librement sur l'axe du pignon 8 entre deux butées 12a, 12b et est maintenu contre l'une ou l'autre de ces butées 12a, 12b par un organe élastique 13 situé à l'extrémité libre d'une lame ressort et qui comporte deux faces d'inclinations opposées, alternativement en prise avec un élément lia qui met sous tension la lame ressort de l'organe élastique 13 solidaire de l'organe mobile 11 et permet la bascule de l'organe mobile 11. A movable member 11, bearing a scale corresponding to the indication of the moon phases of a lunar cycle, is pivotally mounted on the axis of the pinion 8 of the moon phase indicator. This movable member 11 is able to pivot freely on the axis of the pinion 8 between two stops 12a, 12b and is held against one or the other of these stops 12a, 12b by an elastic member 13 located at the free end of a leaf spring and which has two faces of opposite inclinations, alternately in engagement with an element 11a which puts under tension the blade spring of the elastic member 13 integral with the movable member 11 and allows the rocker of the movable member 11.
Cet organe mobile 11 comporte encore une ouverture en arc de cercle 11b, concentrique à l'axe du pignon 8, dans la- quelle la cheville 8b du plateau 8a est engagée. La dimension angulaire de cette ouverture en arc de cercle 11b correspond à un demi-cycle de lune moins un pas du pignon 8 du mobile indicateur des phases de lune entraîné par le secteur denté 7. De ce fait, à la fin de chaque demi-cycle de lune, la cheville 8b rencontre une extrémité de l'ouverture en arc de cercle 11b et entraîne l'organe mobile 11. Au cours de cet entraînement, l'élément lia passe d'une face inclinée à l'autre de l'organe élastique 13, ce qui a pour effet d' inverser le couple exercé par cet organe élastique 13 sous tension sur l'organe mobile 11, qui est de ce fait déplacé contre l'autre des deux butées 12a, 12b.  This movable member 11 further comprises an opening in an arc 11b, concentric with the axis of the pinion 8, in which the pin 8b of the plate 8a is engaged. The angular dimension of this opening in an arc of circle 11b corresponds to a half-moon cycle minus one step of the pinion 8 of the mobile moon phase indicator driven by the toothed sector 7. Therefore, at the end of each half moon cycle, the ankle 8b meets one end of the opening in a circular arc 11b and drives the movable member 11. During this training, the element 11a passes from one inclined face to the other of the elastic member 13, which has the effect of reversing the torque exerted by the resilient member 13 under tension on the movable member 11, which is thereby moved against the other of the two stops 12a, 12b.
Les six phases de lune que porte l'organe mobile 11 sont destinées à apparaître sélectivement et alternativement à travers trois ouvertures 14 ménagées dans le cadran de la pièce d'horlogerie (Figures 1 et 2). Ces ouvertures 14 ont un espacement angulairement autour du centre de pivotement de l'organe indicateur 15 double de l'espacement angulaire entre les phases de lunes portées par l'organe mobile 11, lequel correspond au déplacement angulaire de l'organe mobile 11 entre les butées 12a, 12b, en sorte que lorsque cet organe mobile 11 est déplacé d'une butée 12a à l'autre 12b ou vice versa, une autre série de phases de lune apparaît dans les ouvertures 14. De ce fait, une phase de lune portée par l'organe mobile 11 sur deux est une phase de lune croissante, les autres phase alternant avec les premières étant relatives aux phases de lune décroissante. Ceci permet d'afficher alternativement les phases de lune croissante lorsque l'index indicateur de phases de lune 15 se déplace dans le sens des aiguilles d'une montre et les phases de lune décroissante lorsque cet index indicateur de phases de lune 15 se déplace en sens inverse. L'organe mobile 11 peut encore porter deux flèches de sens opposés pour indiquer le sens de déplacement de l'index indicateur des phases de lune 15. Ces flèches peuvent apparaître alternativement dans une ouverture 16, en même temps que lors du changement des phases de lune. The six moon phases carried by the movable member 11 are intended to appear selectively and alternately through three openings 14 formed in the dial of the timepiece (Figures 1 and 2). These openings 14 have an angular spacing around the center of pivoting of the indicator member 15 double the angular spacing between the phases of moons carried by the movable member 11, which corresponds to the angular displacement of the movable member 11 between the stops 12a, 12b, so that when this movable member 11 is moved from one stop 12a to the other 12b or vice versa, another series of moon phases appears in the openings 14. As a result, a moon phase carried by the movable member 11 in two is an increasing moon phase, the other phase alternating with the first being related to decreasing moon phases. This makes it possible to alternatively display the increasing moon phases as the moonphase indicator 15 moves in the clockwise direction and the decreasing moon phases when the moon phase indicator index 15 moves in reverse. The movable member 11 may still carry two arrows in opposite directions to indicate the direction of movement of the index indicator moon phases 15. These arrows may appear alternately in an opening 16, at the same time as when changing the phases of Moon.
