Description

La présente invention a pour objet une pièce d'horlogerie munie d'un mécanisme d'affichage des phases de lune comprenant un mobile en liaison cinématique avec le rouage de minuterie, un élément d'entraînement périodique entre ce mobile en liaison cinématique avec rouage de minuterie et un mobile monté pivotant autour d'un axe et dont le rapport de denture est choisi pour faire un tour pendant un cycle de lune, une came ayant un mouvement circulaire et solidaire dudit mobile, un palpeur de came monté autour d'un axe de pivotement, des moyens élastiques pour presser le palpeur de came contre le profil de ladite came, un secteur denté centré sur ledit axe de pivotement, solidaire de ce palpeur de came et en prise avec un mobile denté indicateur des phases de lune.The present invention relates to a timepiece provided with a moon phase display mechanism comprising a mobile in kinematic connection with the timer train, a periodic drive element between the mobile in kinematic connection with the gear train. timer and a mobile mounted pivoting about an axis and whose gear ratio is chosen to turn during a moon cycle, a cam having a circular motion and secured to said mobile, a cam follower mounted about an axis pivoting means, elastic means for pressing the cam follower against the profile of said cam, a toothed sector centered on said pivot axis, integral with the cam follower and in engagement with a toothed indicator moon phase indicator.

On a déjà proposé un mécanisme indicateur des phases de lune à retour rétrograde de ce type dans le EP 1 321 832 . Le but de ce mécanisme est de permettre de placer l'indicateur de phases de lune pratiquement à n'importe quel endroit de la surface du cadran et que cet indicateur occupe une surface minimum.A feedback phase moon phase indicator mechanism of this type has already been proposed in the EP 1 321 832 . The purpose of this mechanism is to allow the moonphase indicator to be placed almost anywhere on the surface of the dial and this indicator occupies a minimum area.

Dans le cas d'un affichage des phases de lune à retour rétrograde, le retour de l'indicateur pour revenir en position de départ correspond à un déplacement rapide dont le seul but est le retour en position de départ. Dans un affichage de ce type destiné à économiser de la place, le mouvement de retour rétrograde constitue un mouvement à vide qui contribue en fait à perdre de l'espace d'affichage.In the case of a display of the retrograde return moon phases, the return of the indicator to return to the starting position corresponds to a rapid movement whose sole purpose is to return to the starting position. In a space-saving display of this type, the retrograde return movement is a no-load movement which actually contributes to losing display space.

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'utilisation du mouvement de retour pour afficher la seconde partie du cycle de la lune permet dans le même espace de réaliser un second affichage, doublant ainsi la course utile de l'organe indicateur des phases de lune.The use of the return movement to display the second part of the moon cycle makes it possible in the same space to make a second display, thus doubling the useful stroke of the moon phase indicator organ.

Avantageusement, l'échelle vis-à-vis de laquelle se déplace l'organe indicateur est au moins en partie située sur un organe mobile portant les phases du cycle de lune, monté oscillant entre deux butées sur l'axe dudit mobile indicateur, au-dessous du cadran de la pièce d'horlogerie muni de fenêtres, à travers lesquelles une première partie des phases de lune est visible dans une première position limite d'oscillation dudit organe mobile portant les phases de lunes et une seconde partie des phases de lune est visible dans une seconde position limite d'oscillation dudit organe mobile portant les phases de lune, celui-ci comportant un élément apte à venir en prise avec un élément d'entraînement solidaire dudit mobile indicateur aux deux extrémités du mouvement d'oscillation de ce mobile indicateur pour déplacer ledit organe portant les phases de lune d'une butée à l'autre, un organe élastique étant encore en prise avec cet organe portant les phases de lune pour le maintenir alternativement contre chacune desdites butées entre deux déplacements par ledit élément d'entraînement.Advantageously, the scale with respect to which the indicator member moves is at least partially located on a movable member carrying the phases of the moon cycle, mounted oscillating between two stops on the axis of said indicator mobile, at below the dial of the timepiece provided with windows, through which a first part of the moon phases is visible in a first limit position of oscillation of said movable member carrying the phases of moons and a second part of the phases of the moon is visible in a second limit position of oscillation of said movable member carrying the moon phases, the latter comprising an element capable of coming into engagement with a driving element secured to said mobile indicator at both ends of the oscillation movement of this movable indicator for moving said member carrying the moon phases from one stop to the other, an elastic member being still engaged with this member carrying the moon phases for the alternately maintain against each of said stops between two displacements by said drive element.

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.

  • 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;
  • 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.
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 FIG. the timepiece object of this invention.
  • The figure 1 is a front view of this embodiment showing a first position of the display members;
  • the figure 2 is a view similar to the figure 1 showing a second position of the display members;
  • the figure 3 is a view of the display mechanism in the position of the display members illustrated by the figure 1 ;
  • the figure 4 is a view of the display mechanism in the position of the display members illustrated by the figure 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 une butée 5 par un ressort 4.The mechanism illustrated by the 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 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 a stop 5 by a spring 4.

A chaque rotation du mobile 2, le doigt d'entraînement 3 rencontre une dent d'une étoile à sept branches 6 positionnée par un sautoir 7. Cette étoile 6 est solidaire d'un pignon 8 qui est relié à un mobile 9 par l'intermédiaire d'une roue 10. Le rapport d'engrenage entre les roues et pignons 8-9 est choisi pour que le mobile 9 fasse une révolution en 29 ½ jours, correspondant approximativement à un cycle de la lune avec une erreur d'un jour sur trois cents ans.At each rotation of the mobile 2, the drive finger 3 encounters a tooth of a star with seven branches 6 positioned by a jumper 7. This star 6 is integral with a pinion 8 which is connected to a mobile 9 by the The gear ratio between the wheels and pinions 8-9 is chosen so that the mobile 9 makes a revolution in 29 ½ days, corresponding approximately to a cycle of the moon with an error of one day. over three hundred years.

Ce mobile 9 porte une came 11 dont le profil présente deux courbes dont les distances respectives de l'axe de pivotement du mobile 9 varient de manière continue, les extrémités respectives adjacentes de ces courbes, les plus proches 11a, respectivement les plus éloignées 11b de l'axe dudit mobile, étant situées sur un diamètre du mobile 9.This mobile 9 carries a cam 11 whose profile has two curves whose respective distances from the pivot axis of the mobile 9 vary continuously, the respective adjacent ends of these curves, the closest 11a, respectively the farthest 11b of the axis of said mobile, being located on a diameter of the mobile 9.

Un palpeur de came 12 pivoté sur un axe 12c comporte un galet ou un plot 12a et un secteur denté 12b centré sur l'axe de pivotement et en prise avec un pignon 13 servant de mobile indicateur des phases de lune et dont l'axe est solidaire d'un index ou aiguille 13c (figures 1, 2) qui est déplacé en regard d'une échelle 14. Ce pignon 13 est encore en prise avec un second secteur denté 15 soumis à la force d'un ressort de rappel 16 qui sert à maintenir le plot 12a du palpeur de came 12 en contact avec le profil de la came 11. Le pignon 13 est encore solidaire d'un plateau 13a auquel une cheville 13b est fixée.A cam follower 12 pivoted on an axis 12c comprises a roller or a stud 12a and a toothed sector 12b centered on the axis of pivoting and engaged with a pinion 13 serving as mobile indicator moon phases and whose axis is secured to an index or needle 13c ( Figures 1, 2 ) which is moved opposite a ladder 14. This pinion 13 is still engaged with a second toothed sector 15 subjected to the force of a return spring 16 which serves to keep the stud 12a of the cam follower 12 in contact with the profile of the cam 11. The pinion 13 is further secured to a plate 13a to which a pin 13b is fixed.

Un organe mobile 17, portant une échelle correspondant à l'indication des phases de lune d'un cycle lunaire, est monté pivotant sur l'axe du pignon 13 de l'indicateur des phases de lune. Cet organe mobile 17 est susceptible de pivoter librement sur l'axe du pignon 13 entre deux butées 18a, 18b et est maintenu contre l'une ou l'autre de ces butées 18a, 18b par un organe élastique 19 situé à l'extrémité libre d'une lame ressort et qui comporte deux faces d'inclinations opposées, alternativement en prise avec un élément 17a qui met sous tension la lame ressort de l'organe élastique 19 solidaire de l'organe mobile 17.A movable member 17, bearing a scale corresponding to the indication of the moon phases of a lunar cycle, is pivotally mounted on the axis of the pinion 13 of the moon phase indicator. This movable member 17 is pivotable freely on the axis of the pinion 13 between two stops 18a, 18b and is held against one or the other of these stops 18a, 18b by an elastic member 19 located at the free end a leaf spring and which has two faces of opposite inclinations alternately in engagement with an element 17a which puts under tension the blade spring of the elastic member 19 secured to the movable member 17.

Cet organe mobile 17 comporte encore une ouverture en arc de cercle 17b, concentrique à l'axe du pignon 13, dans laquelle la cheville 13b du plateau 13a est engagée. La dimension angulaire de cette ouverture en arc de cercle 17b correspond à un demi-cycle de lune moins un pas du pignon 13 du mobile indicateur des phases de lune entraîné par le secteur denté 12b du palpeur de came 12. De ce fait, à la fin de chaque demi-cycle de lune, la cheville 13b rencontre une extrémité de l'ouverture en arc de cercle 17b et entraîne l'organe mobile 17. Au cours de cet entraînement, l'élément 17a passe d'un face inclinée à l'autre de l'organe élastique 19, ce qui a pour effet d'inverser le couple exercé par cet organe élastique 19 sous tension sur l'organe mobile 17, qui est de ce fait déplacé contre l'autre des deux butées 18a, 18b.This movable member 17 also has an opening in an arc 17b, concentric with the axis of the pinion 13, in which the pin 13b of the plate 13a is engaged. The angular dimension of this opening in the form of an arc of circle 17b corresponds to a half-moon cycle minus one step of the pinion 13 of the mobile moon phase indicator driven by the toothed sector 12b of the cam sensor 12. As a result, at the At the end of each half-moon cycle, the pin 13b meets one end of the arcuate opening 17b and drives the movable member 17. During this drive, the element 17a passes from an inclined face to the other of the elastic member 19, which has the effect of reversing the torque exerted by this resilient member 19 under tension on the movable member 17, which is thereby moved against the other of the two stops 18a, 18b.

Les six phases de lune que porte l'organe mobile 17 sont destinées à apparaître sélectivement et alternativement à travers trois ouvertures 20 ménagées dans le cadran de la pièce d'horlogerie (Figures 1 et 2). Ces ouvertures ont un espacement angulairement autour du centre de pivotement de l'organe indicateur 13c double de l'espacement angulaire entre les phases de lunes portées par l'organe mobile 17, lequel correspond au déplacement angulaire de l'organe mobile 17 entre les butées 18a, 18b, en sorte que lorsque cet organe mobile 17 est déplacé d'une butée 18a à l'autre 18b ou vice versa, une autre série de phases de lune apparaît dans les ouvertures 20. De ce fait, une phase de lune portée par l'organe mobile 17 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 13c se déplace dans le sens des aiguilles d'une montre et les phases de lune décroissante lorsque cet index indicateur de phases de lune 13c se déplace en sens inverse. L'organe mobile 17 peut encore porter deux flèches de sens opposés pour indiquer le sens de déplacement de l'index indicateur des phases de lune 13c. Ces flèches peuvent apparaître alternativement dans une ouverture 21, en même temps que lors du changement des phases de lune.The six moon phases carried by the movable member 17 are intended to appear selectively and alternately through three openings 20 formed in the dial of the timepiece ( Figures 1 and 2 ). These openings have an angular spacing around the center of pivoting of the indicator member 13c double the angular spacing between the moon phases carried by the movable member 17, which corresponds to the angular displacement of the movable member 17 between the stops 18a, 18b, so that when this movable member 17 is moved from one stop 18a to the other 18b or vice versa, another series of moon phases appears in the openings 20. As a result, a moon phase is brought by the movable member 17 of two is an increasing moon phase, the other phase alternating with the first being relative to decreasing moon phases. This makes it possible to alternately display the increasing moon phases when the moon phase indicator index 13c moves in the clockwise direction and the decreasing moon phases when this moon phase indicator index 13c moves in reverse. The movable member 17 can still carry two arrows in opposite directions to indicate the direction of movement of the index indicator moon phases 13c. These arrows may appear alternately in an opening 21, at the same time as during the change of moon phases.
