Abstract

The mechanism has a watch movement including an hour wheel (28), a wheel (30) for phases of the moon and a mobile (32) for stages of tides kinematically linked to the hour wheel and designed to bear units displaying phases and tides of the moon. The mobile for stages of the tides is kinematically linked to the wheel hour through the wheel for the phases of the moon. A scale with graduations is provided in the mechanism, where a step between two gradations represents one hour.

Description

L'invention se rapporte au domaine de l'horlogerie mécanique. Elle concerne plus précisément un mécanisme d'indication des phases de lune et des marées.The invention relates to the field of mechanical watchmaking. It relates more specifically to a mechanism for indicating moon phases and tides.

Le mouvement de la montre a souvent été utilisé pour donner une indication sur un phénomène naturel périodique tel que la succession des jours, des mois, des phases de lune etc.... La marée est un tel phénomène, résultant des attractions de la lune et du soleil sur la mer, de sorte que sa période est liée au mois lunaire. L'intervalle moyen entre deux hautes mers consécutives est d'environ douze heures et vingt cinq minutes et l'heure de la marée haute prend la même valeur périodiquement, tous les vingt neuf jours douze heures quarante quatre minutes et deux virgule huit secondes, durée d'un mois lunaire.The movement of the watch has often been used to give an indication of a periodic natural phenomenon such as the succession of days, months, phases of the moon, etc. The tide is such a phenomenon, resulting from the attractions of the moon and the sun on the sea, so that its period is related to the lunar month. The mean interval between two consecutive high seas is about twelve hours and twenty-five minutes, and the high tide hour is the same periodically, every twenty-nine days, twelve forty-four minutes, and two decimal eight seconds, duration. of a lunar month.

Du fait de la périodicité du phénomène des marées, l'affichage des marées a déjà fait l'objet de plusieurs développements horlogers. L'un d'eux est décrit dans le brevet CH 278335 déposé par Ed. Heuer and Co. en 1949. Certaines réalisations combinent, sur une même montre, l'affichage des phases de lune et des marées. L'une d'entre elles est présentée dans le document US 5327400 (Nouvelle Lemania SA, Eberhard & Cie SA). Les phénomènes des phases de lune et des marées étant liés, il peut être intéressant, dans certaines occasions, en cas d'arrêt du mécanisme de la montre, par exemple, de régler les affichages de l'un et de l'autre simultanément. Toutefois, aucune réalisation actuelle ne permet un tel réglage.Because of the periodicity of the tides phenomenon, the display of tides has already been the subject of several watch developments. One of them is described in the patent CH 278335 deposited by Ed. Heuer and Co. in 1949. Some achievements combine, on the same watch, the display of moon phases and tides. One of them is presented in the document US 5327400 (New Lemania SA, Eberhard & Co. SA). The phenomena of moon phases and tides are linked, it may be interesting, in some cases, in case of stopping the watch mechanism, for example, to adjust the displays of one and the other simultaneously. However, no current realization allows such adjustment.

La présente invention a pour but de palier cet inconvénient en proposant un mécanisme permettant de régler l'indication des phases de lune et des marées par une manipulation unique.The present invention aims to overcome this disadvantage by providing a mechanism for adjusting the indication of moon phases and tides by a single manipulation.

Plus précisément, l'invention concerne un mécanisme d'indication des marées et des phases de lune, destiné à équiper un mouvement d'horlogerie muni d'une roue des heures, et comportant une roue de phases de lune et un mobile de marées tous deux reliés cinématiquement à la roue des heures et respectivement destinés à porter des moyens d'affichage des phases de lune et de marée. Selon l'invention, le mobile des marées est relié cinématiquement à la roue des heures par l'intermédiaire de la roue des phases de lune.More specifically, the invention relates to a mechanism for indicating tides and moon phases, intended to equip a watch movement provided with an hour wheel, and comprising a moon phase wheel and a mobile tide both kinematically connected to the hour wheel and respectively intended to carry display means of the moon and tide phases. According to the invention, the tide wheel is kinematically connected to the hour wheel by means of the moon phase wheel.

Avantageusement, le mécanisme selon l'invention comporte, en outre, des moyens pour effectuer la correction simultanée des phases de lune et des marées.Advantageously, the mechanism according to the invention further comprises means for effecting the simultaneous correction of moon phases and tides.

Par ailleurs, la marée est, par nature, un phénomène local. L'heure des marées hautes et basses varie d'un endroit à l'autre d'une même côte, sans que les phases de lune changent de la même façon. Il est donc particulièrement intéressant de disposer d'une montre permettant un réglage des marées indépendant de celui des phases de lune. Le mécanisme selon l'invention offre une telle possibilité.Moreover, the tide is, by nature, a local phenomenon. The time of the high and low tides varies from one place to another of the same coast, without the moon phases changing in the same way. It is therefore particularly interesting to have a watch allowing a tide adjustment independent of that of the moon phases. The mechanism according to the invention offers such a possibility.

Plus précisément, l'invention concerne un mécanisme, caractérisé en ce qu'il comporte, en outre, des moyens de correction de l'indication des marées et des moyens de débrayage de la liaison cinématique entre le mobile des marées et la roue des phases de lune, situés entre les moyens d'affichage de phases de lune et de marée.More specifically, the invention relates to a mechanism, characterized in that it further comprises means for correcting the indication of the tides and disengagement means of the kinematic link between the tide mobile and the phase wheel. of moon, located between the display means of moon phases and tide.

Dans une réalisation particulière, le mobile des marées comporte une première roue dentée solidaire des moyens d'affichage des marées et coopérant avec les moyens de correction, une deuxième roue dentée, reliée cinématiquement à la roue de phase de lune, et des moyens de liaison des première et deuxième roues dentées agencés pour être débrayés lorsque le couple appliqué par les moyens de correction sur la première roue dépasse une valeur limite.In a particular embodiment, the tide wheel comprises a first toothed wheel integral with the tide display means and cooperating with the correction means, a second gear wheel, kinematically connected to the moon phase wheel, and connecting means. first and second gears arranged to be disengaged when the torque applied by the correction means on the first wheel exceeds a limit value.

D'autres caractéristiques apparaîtront plus clairement à la lecture de la description qui suit, faite en référence aux dessins annexés, dans lesquels :

  • la figure 1 illustre un cadran associé au mécanisme selon l'invention,
  • la figure 2 représente une réalisation du mécanisme selon l'invention,
  • la figure 3 illustre une vue en coupe d'un mobile selon l'invention, et
  • la figure 4 représente un élément de ce mobile en vue de dessus.
Other characteristics will appear more clearly on reading the description which follows, made with reference to the appended drawings, in which:
  • FIG. 1 illustrates a dial associated with the mechanism according to the invention,
  • FIG. 2 represents an embodiment of the mechanism according to the invention,
  • FIG. 3 illustrates a sectional view of a mobile according to the invention, and
  • Figure 4 shows an element of this mobile in top view.

Le mécanisme d'indication des phases de lune et des marées selon l'invention, est destiné à équiper une montre dont un cadran est représenté en figure 1. Ce cadran comporte un affichage des phases de lune 10 et un affichage des marées 12.The mechanism for indicating moon phases and tides according to the invention is intended to equip a watch, a dial of which is shown in FIG. 1. This dial comprises a moon phase display 10 and a tide display 12.

L'affichage des phases de lune 10, de type classique, est situé à six heures sur le cadran. L'affichage des marées 12 est formé d'un petit cadran rond 14 situé à neuf heures et doté d'une échelle munie de graduations. Comme on le comprendra ci-après, cette échelle permet d'indiquer les heures auxquelles ont lieu les marées hautes et basses. Dans le mode de réalisation illustré, le pas entre deux graduations représente une heure. L'échelle permet d'afficher deux marées hautes et deux marées basses successives, c'est-à-dire que les graduations s'étendent sur environ 24 heures et 50 minutes, soit une double période du phénomène des marées. En pratique, deux graduations sont espacées de quatorze degrés, vingt neuf minutes et quarante huit secondes, ce qui ne permet pas une répartition régulière sur toute la périphérie du cadran. Pour pallier cet inconvénient, l'échelle n'est représentée que sur une portion du cadran.The moon phase display 10, of conventional type, is located at six o'clock on the dial. The tide display 12 is formed of a small round dial 14 located at nine o'clock and provided with a scale provided with graduations. As will be understood below, this scale makes it possible to indicate the hours at which high and low tides occur. In the illustrated embodiment, the pitch between two graduations represents one hour. The scale shows two high tides and two successive low tides, that is to say that the graduations extend over about 24 hours and 50 minutes, a double period of the tides phenomenon. In practice, two graduations are spaced fourteen degrees, twenty-nine minutes and forty-eight seconds, which does not allow a regular distribution over the entire periphery of the dial. To overcome this drawback, the scale is represented only on a portion of the dial.

Un disque d'affichage 16 apparaissant dans le cadran 14 est entraîné à la fréquence d'un tour par période de vingt neuf jours, douze heures et quarante cinq minutes, soit sensiblement un mois lunaire, par le mécanisme selon l'invention qui sera décrit ci-après. Ce disque représente sensiblement un huit sur fond de lignes perpendiculaires à son axe longitudinal. Les deux extrémités du huit indiquent, à leurs points de tangence 18 et 20 avec la graduation, les heures des marées hautes, tandis que le noeud 22 du huit indique, à l'aide des lignes du fond, l'heure des marées basses.A display disc 16 appearing in the dial 14 is driven at the frequency of one revolution per period of twenty-nine days, twelve hours and forty-five minutes, or substantially one lunar month, by the mechanism according to the invention which will be described. below. This disc substantially represents an eight on the bottom of lines perpendicular to its longitudinal axis. The two ends of the eight indicate, at their points of tangency 18 and 20 with the graduation, the hours of the high tides, while the node 22 of the eight indicates, with the help of the lines of the bottom, the time of the low tides.

Le mécanisme d'indication des phases de lune et des marées représenté en figure 2 et associé au cadran 14, comprend, montés sur une platine 24:

  • un train de rouage 26 comportant, reliés cinématiquement, une roue des heures 28, une roue des phases de lune 30 et un mobile des marées 32,
  • un premier dispositif de correction simultanée 34 de l'affichage des phases de lune et des marées, et
  • un second dispositif de correction 36 de l'affichage des marées indépendant de l'affichage des phases de lune.
The mechanism for indicating the moon phases and the tides shown in FIG. 2 and associated with the dial 14 comprises, mounted on a plate 24:
  • a gear train 26 having, kinematically connected, a wheel 28 hours, a moon phase wheel 30 and a tide mobile 32,
  • a first simultaneous correction device 34 for displaying moon phases and tides, and
  • a second correction device 36 of the tide display independent of the display of moon phases.

Le point de départ du train de rouage 26 est la roue des heures 28 située au centre de la platine 24, et effectuant un tour toutes les douze heures. Une roue intermédiaire 38 engrène avec la roue 28, et porte un pignon 40 qui engrène avec une roue dentée 42 sur laquelle est monté, libre en rotation, un doigt 44. La roue 42 est munie d'une butée 46 destinée à exercer une poussée sur le doigt 44, comme explicité par la suite, tout en limitant la rotation de ce dernier. Une roue en étoile à sept dents 48, solidaire d'un pignon 50, est disposée au voisinage de la roue 42, de sorte que l'une de ses dents se trouve toujours engagée sur le trajet du doigt 44. La roue en étoile 48 est positionnée par un ressort sautoir 52. Le pignon 50 engrène avec la roue des phases de lune 30.The starting point of the gear train 26 is the hour wheel 28 located in the center of the plate 24, and making a turn every twelve hours. An intermediate wheel 38 meshes with the wheel 28, and carries a pinion 40 which meshes with a toothed wheel 42 on which is mounted, free to rotate, a finger 44. The wheel 42 is provided with a stop 46 intended to exert a thrust on the finger 44, as explained later, while limiting the rotation of the latter. A seven-star star wheel 48, integral with a pinion 50, is disposed in the vicinity of the wheel 42, so that one of its teeth is always engaged on the path of the finger 44. The star wheel 48 is positioned by a jumper spring 52. The pinion 50 meshes with the moon phase wheel 30.

Un mobile intermédiaire relie la roue des phases de lune 30 et le mobile des marées 32. Plus particulièrement, le mobile intermédiaire comporte un pignon 54 en prise avec la roue des phases de lune 30 et une roue intermédiaire des marées 56 solidaire du pignon 54 et engrenant avec le mobile des marées 32. Le rapport des dentures du pignon 54 à la roue intermédiaire des marées 56 vaut un demi.An intermediate mobile connects the moon phase wheel 30 and the mobile tides 32. More particularly, the intermediate mobile comprises a pinion 54 engaged with the moon phase wheel 30 and a tide intermediate wheel 56 integral with the pinion 54 and meshing with the mobile tides 32. The gear ratio of pinion 54 to the intermediate wheel tides 56 is worth half.

Le mobile des marées 32, représenté en figure 3, comporte une roue à dents de loup 58 solidaire d'un ressort-friction 60. Le tout est monté coaxialement sur une roue dentée 62 de diamètre voisin de celui de la roue 58. Pour ce faire, la roue dentée 62 est dotée d'une creusure annulaire 64, pratiquée dans sa surface supérieure, et formant un logement pour le ressort-friction 60. La paroi latérale 66 de la creusure 64 située du côté de l'extérieur de la roue 62 forme un angle légèrement rentrant, pour des raisons qui apparaîtront ultérieurement.The tide wheel 32, shown in FIG. 3, comprises a wolf wheel 58 integral with a friction spring 60. The whole is mounted coaxially on a toothed wheel 62 of a diameter close to that of the wheel 58. the gearwheel 62 is provided with an annular recess 64 formed in its upper surface and forming a housing for the friction spring 60. The side wall 66 of the recess 64 located on the outside of the wheel 62 forms a slightly tilting angle, for reasons that will appear later.

Le ressort-friction 60 illustré sur la figure 4, possède une partie centrale circulaire 68 et une pluralité (au moins deux sont nécessaires) de branches identiques 70a, 70b et 70c, solidaires de la partie centrale 68 et réparties régulièrement à sa périphérie. Chaque branche 70a, 70b et 70c est reliée à la partie centrale 68 par un bras essentiellement radial, et s'étend le long de celle-ci en en suivant le contour sans la toucher. Les branches 70a, 70b et 70c se terminent par des patins 72a, 72b et 72c, dont la surface destinée à exercer un frottement présente un rayon de courbure sensiblement égal à celui de la paroi 66. Les branches 70a, 70b, 70c sont, en outre, dimensionnées de manière à présenter un comportement élastique s'exerçant dans le plan de la partie centrale 68. En cela, le ressort-friction 60 diffère des ressorts-friction bien connus de l'homme de métier, exerçant habituellement une poussée axiale et non latérale.The friction spring 60 illustrated in Figure 4, has a circular central portion 68 and a plurality (at least two are necessary) of identical branches 70a, 70b and 70c, secured to the central portion 68 and regularly distributed at its periphery. Each branch 70a, 70b and 70c is connected to the central portion 68 by a substantially radial arm, and extends along it, following the contour without touching it. The branches 70a, 70b and 70c are terminated by runners 72a, 72b and 72c, whose surface intended to exert a friction has a radius of curvature substantially equal to that of the wall 66. The branches 70a, 70b, 70c are, in in addition, dimensioned to exhibit an elastic behavior exerted in the plane of the central portion 68. In this, the friction spring 60 differs from friction springs well known to those skilled in the art, usually exerting an axial thrust and non-lateral.

Le ressort-friction 60 est logé dans la creusure 64. Le rapport dimensionnel du ressort 60 par rapport à la creusure 64 est choisi de manière à ce que les branches 70a, 70b et 70c soient comprimées et exercent, via les patins 72a, 72b et 72c, une force essentiellement radiale sur la paroi 66. L'angle légèrement rentrant de la paroi 66 assure, en outre, le maintien du ressort-friction 60 dans la creusure 64. Le ressort-friction 60 relie donc les roues 58 et 62, cette liaison pouvant être débrayée en fonction de la différence entre les couples exercés sur chacune de ces deux roues.The friction spring 60 is housed in the recess 64. The dimensional ratio of the spring 60 relative to the recess 64 is chosen so that the branches 70a, 70b and 70c are compressed and exert, via the pads 72a, 72b and 72c, a substantially radial force on the wall 66. The slightly tilting angle of the wall 66 further ensures the retention of the friction spring 60 in the recess 64. The friction spring 60 thus connects the wheels 58 and 62, this link can be disengaged according to the difference between the torques exerted on each of these two wheels.

Ainsi, lorsque la roue des heures 28 tourne, la roue dentée 42 est entraînée par l'intermédiaire de la roue 38 et du pignon 40, à la fréquence d'un tour par jour. Le doigt 44 est entraîné par la butée 46 jusqu'à venir au contact de la dent de la roue en étoile 48 engagée sur son trajet. Puis, sous l'action de la butée 46, il exerce une poussée sur cette dent, faisant ainsi tourner, à l'aide du ressort sautoir 52, la roue en étoile 48 d'un septième de tour par jour. Le pignon 50, solidaire de la roue en étoile 48, fait alors pivoter la roue des phases de lune 30 à la fréquence d'un tour sensiblement tous les deux mois lunaires, soit 59 jours, une heure et trente minutes. La roue des phases de lune 30 entraîne à son tour la roue dentée 62 du mobile des marées 32 par l'intermédiaire de la roue 56 et du pignon 54. La roue dentée 62 est elle-même liée à la roue à dents de loup 58 par le couple de friction exercée par le ressort-friction 60, et l'ensemble du mobile des marées 32 est entraîné, par l'intermédiaire de la roue dentée 62, à la fréquence d'un tour par mois lunaire.Thus, when the hour wheel 28 rotates, the toothed wheel 42 is driven via the wheel 38 and pinion 40, at the frequency of one revolution per day. The finger 44 is driven by the stop 46 until it comes into contact with the tooth of the star wheel 48 engaged in its path. Then, under the action of the abutment 46, it exerts a thrust on the tooth, thereby rotating, with the aid of the jumper spring 52, the star wheel 48 of a seventh turn per day. The pinion 50, integral with the star wheel 48, then rotates the moon phase wheel 30 at a frequency of a turn substantially every two lunar months, 59 days, one hour and thirty minutes. The moon phase wheel 30 in turn drives the toothed wheel 62 of the tide wheel 32 by through the wheel 56 and the pinion 54. The toothed wheel 62 is itself linked to the wolf wheel 58 by the frictional torque exerted by the friction spring 60, and the whole of the mobile tides 32 is driven, via the gear wheel 62, at the frequency of one revolution per lunar month.

Le dispositif de correction 34 est formé d'un poussoir 74 actionnable depuis l'extérieur de la montre et coopérant avec la roue en étoile 48, et d'un ressort-lame 76 en appui sur le poussoir 74 pour assurer son retour à sa position de repos. Lorsque l'utilisateur exerce une pression sur le poussoir 74, la roue en étoile 48 avance d'un pas, entraînant la roue des phases de lune 30 et, en même temps, le mobile des marées 32 par l'intermédiaire de la roue 56 et du pignon 54. Les affichages des phases de lune et des marées sont ainsi corrigés simultanément après, par exemple, un arrêt du mécanisme de la montre.The correction device 34 is formed of a pusher 74 operable from outside the watch and cooperating with the star wheel 48, and a leaf spring 76 resting on the pusher 74 to ensure its return to its position. rest. When the user exerts pressure on the pusher 74, the star wheel 48 advances by one step, driving the moon phase wheel 30 and, at the same time, the tide wheel 32 via the wheel 56 and the pinion 54. Displays of the moon phases and tides are corrected simultaneously after, for example, a stop of the mechanism of the watch.

Le dispositif de correction 36 est constitué d'une bascule à cliquet 78 coopérant avec le mobile des marées 32, d'un poussoir 80 coopérant avec cette bascule, et d'un ressort-lame 82 en appui sur cette dernière.The correction device 36 consists of a ratchet rocker 78 cooperating with the mobile tides 32, a pusher 80 cooperating with this rocker, and a leaf spring 82 bearing on the latter.

Lorsque l'utilisateur exerce une pression sur le poussoir 80, celui-ci exerce à son tour une poussée sur la bascule 78 qui entraîne en rotation la roue à dents de loup 58, à l'aide du bec du cliquet. Le ressort-friction 60 solidaire de la roue à dents de loup 58 exerce sur la roue dentée 62 un couple de friction inférieur au couple exercé par le ressort sautoir 52 sur la roue en étoile 48. La roue 58 tourne alors indépendamment de la roue dentée 62 et du reste du train de rouage 26. L'angle parcouru par la roue à dents de loup 58 dépend de la pression exercée par l'utilisateur, et peut être, en pratique, aussi faible que souhaité. Le réglage effectué est ainsi sensiblement plus fin qu'il ne le serait si un dispositif à encliquetage était utilisé en lieu et place du ressort-friction 60. Un dispositif à encliquetage ne permet, en effet, qu'un réglage par pas.When the user exerts pressure on the pusher 80, it in turn exerts a thrust on the latch 78 which rotates the wolf wheel 58, using the pawl of the pawl. The friction spring 60 integral with the wolf wheel 58 exerts on the toothed wheel 62 a lower friction torque than the torque exerted by the jumper spring 52 on the star wheel 48. The wheel 58 then rotates independently of the toothed wheel 62 and the rest of the gear train 26. The angle traveled by the wolf wheel 58 depends on the pressure exerted by the user, and can be, in practice, as low as desired. The adjustment made is thus substantially finer than it would be if a snap-in device was used in place of the friction spring 60. A snap-in device allows only a step adjustment.

Lorsque l'utilisateur relâche la pression exercée sur le poussoir 80, le ressort-lame 82 ramène la bascule à cliquet 78 à sa position initiale. Le bec du cliquet s'escamote lors du retour de la bascule 78 de sorte que la roue à dent de loup 58 n'est pas entraînée en sens inverse.When the user releases the pressure exerted on the pusher 80, the leaf spring 82 returns the pawl latch 78 to its initial position. The pawl beak retracts upon the return of the latch 78 so that the wolf tooth wheel 58 is not driven in the opposite direction.

Le mécanisme d'indication des phases de lune et des marées ainsi décrit s'adapte au cadran représenté en figure 1. Le disque d'affichage 16 des marées est solidaire de la roue à dent de loup 58, et celui des phases de lune est solidaire de la roue des phases de lune 30.The mechanism for indicating the moon phases and tides thus described adapts to the dial shown in FIG. 1. The display disk 16 of the tides is integral with the wolf tooth wheel 58, and that of the moon phases is in solidarity with the moon phase wheel 30.

Ainsi est proposé un mécanisme d'indication des phases de lune et des marées, permettant avantageusement le réglage simultané des affichages des phases de lune et des marées, et le réglage indépendant de l'affichage des marées. D'autres variantes peuvent être facilement imaginées sans toutefois sortir du cadre de l'invention. Par exemple, la liaison à friction entre les roues 58 et 62 peut être située ailleurs que sur le mobile 32, du moment qu'elle est située sur la chaîne cinématique entre les disques d'affichage de phases de lune et de marée 16.Thus is provided a mechanism for indicating moon phases and tides, advantageously allowing the simultaneous adjustment of displays of moon phases and tides, and the independent adjustment of the tide display. Other variants can be easily imagined without departing from the scope of the invention. For example, the frictional connection between the wheels 58 and 62 may be located elsewhere than on the mobile 32, as long as it is located on the kinematic chain between the moon and tide phase display disks 16.
