Definitions
- the subject of the present invention is a mechanism for indicating the phases of the moon, in particular for a mechanical watch, comprising a moon disk and a dial comprising a substantially semicircular shaped aperture, the moon disk being rotated in such a manner that to display the indications written on the moon disk through the window to indicate the phases of the moon.
- the present invention also relates to a timepiece comprising such an indication mechanism.
- the moon phase indication devices mentioned above have existed for a very long time and traditionally feature a moon disk on which two yellow or even generally clear circles symbolizing the moon are drawn against a dark background, while that said wicket of substantially semicircular shape in the dial has a separate base in two concave parts, all of which is well known to those skilled in the art.
- the new moon is represented by the dark background when none of the light circles appear in the wicket, the increasing and decreasing moon by a part of the clear circle C-shaped more or less thick when one of the circles is visible but partially concealed by one of the concave parts of the wicket, and the full moon by one of the circles fully visible through the wicket.
- this visible part can also take a D shape, especially during the phases of the lunation known as first and last quarters, and a shape convex, during the phases of the lunation known as gibbous moon increasing or decreasing.
- This appearance of the phases of the moon is therefore not taken into account by the traditional moon phase indication devices mentioned above.
- the prior art apparently does not so far include a mechanism which makes it possible to relatively simple means, to represent in a more real way the lunation in the above-mentioned sense.
- the object of the present invention is therefore to overcome the drawbacks of known moon phase indicating devices and to achieve the above-mentioned advantages, in particular to allow the realization of a mechanism for indicating the phases of the moon for parts of the moon. watchmaking whose display of the phases of the moon corresponds better to reality without increasing the complexity, the volume occupied or the cost of production of the mechanism.
- an indication mechanism for the aforementioned type, in particular for a mechanical timepiece, which is distinguished by the features set forth in claim 1, or even a corresponding timepiece.
- an indication mechanism according to the present invention comprises at least a first occulting disk rotatably housed at least partially between said moon disk and said dial, and a drive train driving said at least first disk occultation so that the indications on the moon disk are obscured at least partially during certain phases of the operation of the mechanism so that the indications appearing through the window correspond substantially to the natural appearance of the moon for the duration of the lunation.
- a moon phase indication mechanism is obtained for timepieces, in particular mechanical watches, which offers a display corresponding more realistically to the real appearance of the visible part on the earth of the watch. surface of the moon illuminated by the sun, this throughout the duration of the lunation.
- the mechanism according to the present invention has the advantage of representing in particular the phases of the moon of the first and last quarter and the gibbous moon increasing and decreasing more in line with the reality that before.
- Variations of the mechanism of indication of the phases of the moon according to the present invention make it possible to have either one or several occultation discs, which can also be housed in a concentric or non-concentric manner with respect to the disc of moon, according to the needs concerning the display of the phases of the moon and / or the technical design of the watch in which the mechanism is to be integrated.
- the arrangement of the occultation discs themselves may vary depending on these parameters. Therefore, the mechanism can be declined in several embodiments and thus has a great flexibility.
- the drive train which rotates said at least first occulting disk normally comprises a first program wheel integral with the moon disk, a second program wheel, and at least one third program wheel which are arranged. , depending on the arrangement of the occultation discs according to the above-mentioned variants, so that these occultation discs are driven intermittently so as to release the view on the indications written on the moon disc or even hide them partially, depending on the phase of the moon to display.
- the mechanism can then be achieved by remaining technically relatively simple and inexpensive in terms of its production.
- the conventional moon phase indicating devices often include a moon disk 1 on which two circles 1.1, 1.2 of a light color symbolizing the moon are inscribed on a dark background 1.3 symbolizing the sky , while a dial 3 comprises a window 3.1 of substantially semicircular shape with a base having two concave portions.
- a dial 3 comprises a window 3.1 of substantially semicircular shape with a base having two concave portions.
- the different phases of the moon are displayed symbolically as schematically illustrated for three phases of the moon to the moon.
- Figures 1a, 1b, and 1c In such devices, the displayed indication is usually always concave except for the new moon and the full moon.
- FIGS. Figures 1a to 1c schematically show the eight main different silhouettes of the lunation, namely in order the new moon, the first crescent, the first quarter, the increasing gibbous moon, the full moon, the waning gibbous moon, the last quarter, and the last crescent
- this representation does not correspond to the actual appearance of the phases of the moon throughout the duration of the lunation.
- the conventional moon phase indication devices as illustrated in FIGS. Figures 1a to 1c can represent in a realistic way the four typical silhouettes of the moon according to the Figures 2a (new moon), 2b (first crescent), 2nd (full moon) and 2h (last crescent).
- a moon phase indicating mechanism is intended to overcome these drawbacks and to permit a realistic display of the visible part of the moon-illuminated surface of the earth on the ground for the duration of the period. the lunation.
- the mechanism comprises for this purpose, in principle, the parts of a conventional device, namely a moon disk 1 and a dial 3 comprising, according to a first embodiment, a window 3.1 of substantially semicircular shape, possibly but not necessarily with a separate base in two concave parts.
- the moon disk 1 may comprise two or more circles 1.1, 1.2 of light color or any other such inscription for representing the moon on a dark background 1.3 illustrating the sky, such as the moon disk 1 in its preferred variant represented at figure 3a . It is rotated to display the indications 1.1, 1.2 written on the moon disk 1 through the window 3.1 to indicate the phases of the moon.
- the drive of the moon disk 1 is normally provided by the base movement in a manner known to those skilled in the art, the more often at a rate of one step per day so that it performs, for example for the case that it has two inscriptions 1.1, 1.2, a rotation of 180 ° by period of lunation, in other words two lunations by rotation cycle. It is clear that the skilled person will adapt this for other arrangements of the moon disk, for example if it has three or more inscriptions.
- an indication mechanism differs generally from the devices of the prior art in that it comprises at least one occulting disc 2.
- This at least first occulting disc 2.1 is housed so rotating and is, in general, at least partially between said moon disk 1 and said dial 3 so as to be superimposed on the moon disk, depending on its position.
- a driving train 4 makes it possible to drive, from the moon disk 1, said at least first occulting disk 2.1 so that the indications 1.1, 1.2 written on the moon disk 1 are obscured at least partially. during certain phases of the operation of the mechanism, so that the indications 1.1, 1.2 appearing through the window 3.1 substantially correspond to the natural appearance of the moon throughout the duration of lunation.
- said at least first occulting disk 2.1 is arranged, according to its position in the mechanism and / or the shape of the window 3.1 formed in the dial 3 or even other parameters, being provided with branches 2.3 and / or wickets 2.5 of a particular form.
- Such an indication mechanism according to the present invention can be declined in several embodiments, some of which will be subsequently explained in more detail in order to illustrate concretely and by way of example the general provision mentioned in the preceding paragraph.
- these embodiments of the mechanism are distinguished, in particular, firstly with respect to the axis of rotation of said or even occultation discs 2 which can be arranged concentrically or non-concentrically with respect to the axis of rotation of the moon disk 1, and, secondly, with regard to the number of occultation disks 2 which may be one, two or more.
- the shape of the occultation discs 2 will be chosen accordingly.
- FIGS. Figures 3a to 3e and 4a at 4h A first embodiment of a moon phase indicating mechanism according to the present invention schematically illustrated in FIGS. Figures 3a to 3e and 4a at 4h is an example of such a mechanism comprising two occultation disks 2.1, 2.2 which are arranged non-concentrically with respect to the moon disk 1.
- This mechanism comprises in particular a first occultation disk 2.1 and a second occultation disk 2.2 housed substantially on either side of the moon disk 1, as is visible in FIG. figure 3c .
- each occultation disk 2.1, 2.2 is interposed between the moon disk 1 and the substantially semicircular aperture 3.1 and can, because of its arrangement and according to its angular position, obscure or not all or part of the indication 1.1, 1.2 written on the moon disk 1 which is intended to be visible in a desired shape through the window 3.1 formed in the dial 3.
- said first - 2.1 and second occultation discs 2.2 used in this embodiment of the mechanism each comprise at least two branches 2.3 which have, seen in their direction of rotation, a front portion 2.4 of a convex shape , respectively right.
- each of these occultation discs 2.1, 2.2 comprises three branches 2.3 having a front part 2.4 convex, straight, respectively concave.
- the third branch having a concave front portion can be removed if the window 3.1 of the dial 3 is not exactly of semicircular shape but comprises a base having two concave-shaped parts which can take the function of this third branch of the occulting disk 2 concerned.
- the two discs 2.1, 2.2 are preferably identical, but are mounted symmetrically relative to each other.
- the drive train 4 which allows, in a general manner, to drive said at least first occulting disk 2.1 will be described in more detail later and by way of example in the context of the description of this first form of FIG. execution of the mechanism, but it is obvious that one skilled in the art will be able to adapt it, in view of the present technical instruction, in a similar manner for the other embodiments which will be described later.

- the drive train 4 comprises a first program wheel 4.1 integral with the moon disc 1.
- the latter being driven normally at a rate of one step per day by the basic movement, the first program wheel 4.1 performs the same rotary motion and thereby drives through at least one intermediate gear, in this case by the intermediate of a first intermediate gear 4.2 and a second intermediate gear 4.3, a second program wheel 4.4.
- the intermediate gears allow via the arrangement of their teeth to choose the ratio of the angular drive between the first - 4.1 and the second program wheel 4.4, so to adapt the gear as needed, for example depending on the arrangement of the occultation discs 2.
- the toothing of the program wheel 4.4 can mesh with at least one program gear 4.5 of a third wheel program 4.6.
- the second program wheel 4.4 can mesh with two program gears 4.5 each carrying a third program wheel 4.6 which are rotatably housed on either side of the second program wheel 4.4.

- the first occulting disk 2.1 remains stationary and the drive train 4 rotates three times in succession the second occultation disk 2.2 as illustrated in FIGS. figures 4e, 4f, 4g, and 4h .
- the second occulting disk 2.2 ensures during this phase of operation of the mechanism that the branches 2.3 having either a convex, straight or concave front part partially obscures that of the inscriptions 1.1, 1.2 of the moon disk 1 appearing through the window 3.1 to display the full moon, the waning gibbous moon, the last quarter and the last crescent.
- the second occultation disk 2.2 remains immobile again and the cycle starts again by rotating the first occulting disk 2.1 in its position where its concave front part occults the moon disk 1.
- the opportune moment of the rotation of the occultation discs 2.1, 2.2 can advantageously be chosen by placing the teeth correspondingly on the periphery of the second program wheel 4.4, their angle of rotation by the arrangement of the third or even third program wheels 4.6, which allows to easily adapt the mechanism for other embodiments.

Abstract
Description
La présente invention a pour objet un mécanisme d'indication des phases 5de la lune, notamment pour montre mécanique, comprenant un disque de lune et un cadran comportant un guichet de forme sensiblement semi-circulaire, le disque de lune étant entraîné en rotation de façon à afficher les indications inscrites sur le disque de lune à travers le guichet pour indiquer les phases de la lune. La présente invention concerne également une pièce d'horlogerie comportant un tel mécanisme d'indication.The subject of the present invention is a mechanism for indicating the phases of the moon, in particular for a mechanical watch, comprising a moon disk and a dial comprising a substantially semicircular shaped aperture, the moon disk being rotated in such a manner that to display the indications written on the moon disk through the window to indicate the phases of the moon. The present invention also relates to a timepiece comprising such an indication mechanism.
Les dispositifs d'indication des phases de la lune de type mentionné ci-dessus existent depuis très longtemps et disposent traditionnellement d'un disque de lune sur lequel deux cercles de couleur jaune voire généralement claire symbolisant la lune sont dessinés sur un fond foncé, tandis que ledit guichet de forme sensiblement semi-circulaire dans le cadran comporte une base séparée en deux parties concaves, le tout étant bien connu à l'homme du métier. Lors de la rotation de ce genre de disque de lune sous le guichet, les différentes phases de la lune sont affichées symboliquement. Notamment, la nouvelle lune est représentée par le fond foncé lorsqu'aucun des cercles clairs n'apparait dans le guichet, la lune croissante et décroissante par une partie du cercle clair en forme de C plus ou moins épaisse lorsqu'un des cercles est visible mais partiellement caché par une desdites parties concaves du guichet, et la pleine lune par un des cercles pleinement visible à travers le guichet.The moon phase indication devices mentioned above have existed for a very long time and traditionally feature a moon disk on which two yellow or even generally clear circles symbolizing the moon are drawn against a dark background, while that said wicket of substantially semicircular shape in the dial has a separate base in two concave parts, all of which is well known to those skilled in the art. When rotating this kind of moon disk under the window, the different phases of the moon are displayed symbolically. In particular, the new moon is represented by the dark background when none of the light circles appear in the wicket, the increasing and decreasing moon by a part of the clear circle C-shaped more or less thick when one of the circles is visible but partially concealed by one of the concave parts of the wicket, and the full moon by one of the circles fully visible through the wicket.
Cette représentation ne correspond pourtant pas à l'apparence réelle des phases de la lune pendant toute la durée de la lunaison. En particulier, le fait que toutes les phases de croissance et de décroissance de la partie visible sur terre de la surface illuminée de la lune sont représentées uniquement par un symbole de forme généralement concave n'est pas conforme à la réalité. En effet, l'aspect naturel des phases de la lune, c'est-à-dire la forme de la partie visible sur terre de la surface de la lune illuminée par le soleil, dépend, en généralisant quelque peu, de la constellation géométrique entre trois points, à savoir l'endroit où se trouve l'observateur sur la terre, la position de la lune par rapport à la terre, et la position du soleil par rapport à la terre et la lune. En fonction de cette constellation géométrique, l'observateur peut voir tout, seulement une partie, ou rien de la moitié de la surface de la lune qui est illuminée par le soleil, en négligeant les cas spécifiques où la lune se trouve dans l'ombre du globe.This representation, however, does not correspond to the actual appearance of the phases of the moon throughout the duration of the lunation. In particular, the fact that all the phases of growth and decay of the visible part of the moon's illuminated surface on earth are represented only by a symbol of Generally concave shape does not conform to reality. Indeed, the natural aspect of the phases of the moon, that is to say, the shape of the visible part on earth of the surface of the moon illuminated by the sun, depends, generalizing somewhat, on the geometric constellation between three points, namely the location of the observer on the earth, the position of the moon in relation to the earth, and the position of the sun in relation to the earth and the moon. According to this geometrical constellation, the observer can see everything, only a part, or nothing of half the surface of the moon which is illuminated by the sun, neglecting the specific cases where the moon is in the shadow of the globe.
Lors des phases de croissance et de décroissance de la partie visible sur terre de la surface illuminée de la lune, cette partie visible peut aussi prendre une forme de D, notamment lors des phases de la lunaison connues comme premier et dernier quartiers, et une forme convexe, lors des phases de la lunaison connues comme lune gibbeuse croissante voire décroissante. Cette apparence des phases de la lune n'est donc pas prise en compte par les dispositifs d'indication des phases de la lune traditionnels mentionnés ci-dessus. A part des dispositifs électroniques tenant compte plus en détail de la forme réelle de la partie visible sur terre de la surface illuminée de la lune, l'art antérieur ne comprend apparemment jusqu'à présent pas encore un mécanisme qui permet, à l'aide des moyens relativement simples, de représenter de manière plus réelle la lunaison dans le sens susmentionné.During the phases of growth and decay of the visible part of the illuminated surface of the moon on earth, this visible part can also take a D shape, especially during the phases of the lunation known as first and last quarters, and a shape convex, during the phases of the lunation known as gibbous moon increasing or decreasing. This appearance of the phases of the moon is therefore not taken into account by the traditional moon phase indication devices mentioned above. Apart from electronic devices which take into account in more detail the actual shape of the visible part of the illuminated surface of the moon on earth, the prior art apparently does not so far include a mechanism which makes it possible to relatively simple means, to represent in a more real way the lunation in the above-mentioned sense.
Au vu de l'art antérieur actuellement connu, il existe alors le besoin de disposer d'un mécanisme d'indication des phases de la lune pour pièces d'horlogerie qui permet d'afficher de manière plus réelle la partie visible sur terre de la surface de la lune illuminée par le soleil, tout en conservant un mode d'affichage classique.In view of the prior art currently known, there is then the need to have a moon phase indication mechanism for timepieces that allows to display more realistically the visible part on earth of the moon-lit surface of the moon, while maintaining a classic display mode.
Le but de la présente invention est donc de remédier aux inconvénients des dispositifs d'indication des phases de la lune connus et de réaliser les avantages susmentionnés, notamment de permettre la réalisation d'un mécanisme d'indication des phases de la lune pour pièces d'horlogerie dont l'affichage des phases de la lune correspond mieux à la réalité sans pour autant trop augmenter la complexité, le volume occupé, voire le coût de production du mécanisme.The object of the present invention is therefore to overcome the drawbacks of known moon phase indicating devices and to achieve the above-mentioned advantages, in particular to allow the realization of a mechanism for indicating the phases of the moon for parts of the moon. watchmaking whose display of the phases of the moon corresponds better to reality without increasing the complexity, the volume occupied or the cost of production of the mechanism.
A cet effet, la présente invention propose un mécanisme d'indication des phases de la lune du type susmentionné, notamment pour pièce d'horlogerie mécanique, qui se distingue par les caractéristiques énoncées à la revendication 1, voire une pièce d'horlogerie correspondant. En particulier, un mécanisme d'indication selon la présente invention comprend au moins un premier disque d'occultation logé de manière rotative au moins partiellement entre ledit disque de lune et ledit cadran, et un rouage d'entraînement entraînant ledit au moins premier disque d'occultation de façon à ce que les indications inscrites sur le disque de lune soient occultées au moins partiellement lors de certaines phases du fonctionnement du mécanisme de manière à ce que les indications apparaissant à travers le guichet correspondent sensiblement à l'aspect naturel de la lune pendant toute la durée de lunaison.For this purpose, the present invention provides a moon phase indication mechanism of the aforementioned type, in particular for a mechanical timepiece, which is distinguished by the features set forth in
Par ces mesures, on obtient un mécanisme d'indication des phases de la lune pour des pièces d'horlogerie, notamment des montres mécaniques, qui offre un affichage correspondant de façon plus réaliste à l'apparence réelle de la partie visible sur terre de la surface de la lune illuminée par le soleil, ceci pendant toute la durée de la lunaison. Par rapport aux dispositifs de l'art antérieur, le mécanisme selon la présente invention a l'avantage de représenter notamment les phases de la lune du premier et dernier quartier ainsi que la lune gibbeuse croissante et décroissante de manière plus conforme à la réalité qu'auparavant.By these measurements, a moon phase indication mechanism is obtained for timepieces, in particular mechanical watches, which offers a display corresponding more realistically to the real appearance of the visible part on the earth of the watch. surface of the moon illuminated by the sun, this throughout the duration of the lunation. Compared to the devices of the prior art, the mechanism according to the present invention has the advantage of representing in particular the phases of the moon of the first and last quarter and the gibbous moon increasing and decreasing more in line with the reality that before.
Des variantes du mécanisme d'indication des phases de la lune selon la présente invention permettent de disposer soit d'un - soit de plusieurs disques d'occultation, qui peuvent par ailleurs être logés de manière concentrique ou non-concentrique par rapport au disque de lune, selon les besoins concernant l'affichage des phases de la lune et/ou la conception technique de la montre dans laquelle le mécanisme doit être intégré. De même, l'agencement du voire des disques d'occultation eux-mêmes peut varier en fonction de ces paramètres. Par conséquent, le mécanisme peut être décliné sous plusieurs formes d'exécution et dispose donc d'une grande flexibilité.Variations of the mechanism of indication of the phases of the moon according to the present invention make it possible to have either one or several occultation discs, which can also be housed in a concentric or non-concentric manner with respect to the disc of moon, according to the needs concerning the display of the phases of the moon and / or the technical design of the watch in which the mechanism is to be integrated. Similarly, the arrangement of the occultation discs themselves may vary depending on these parameters. Therefore, the mechanism can be declined in several embodiments and thus has a great flexibility.
De plus, le rouage d'entraînement qui entraîne en rotation ledit au moins premier disque d'occultation comprend normalement une première roue de programme solidaire du disque de lune, une deuxième roue de programme, et au moins une troisième roue de programme qui sont agencées, en fonction de l'agencement des disques d'occultation selon les variantes susmentionnées, de manière à ce que ces disques d'occultation soient entraînés par intermittence de façon à libérer la vue sur les indications inscrites sur le disque de lune voire de les cacher partiellement, en fonction de la phase de la lune à afficher. Le mécanisme peut alors être réalisé en restant techniquement relativement simple et peu coûteux en ce qui concerne sa production.In addition, the drive train which rotates said at least first occulting disk normally comprises a first program wheel integral with the moon disk, a second program wheel, and at least one third program wheel which are arranged. , depending on the arrangement of the occultation discs according to the above-mentioned variants, so that these occultation discs are driven intermittently so as to release the view on the indications written on the moon disc or even hide them partially, depending on the phase of the moon to display. The mechanism can then be achieved by remaining technically relatively simple and inexpensive in terms of its production.
D'autres caractéristiques, ainsi que les avantages correspondants, ressortiront des revendications dépendantes, ainsi que de la description exposant ci-après l'invention plus en détail.Other features, as well as the corresponding advantages, will emerge from the dependent claims, as well as from the description which sets forth the invention in more detail.

Étant donné que le mécanisme est destiné à être intégré dans une pièce d'horlogerie, notamment dans une montre mécanique, l'entraînement du disque de lune 1 est normalement assuré par le mouvement de base de manière connue à l'homme du métier, le plus souvent à raison d'un pas par jour de sorte qu'il effectue, par exemple pour le cas qu'il comporte deux inscriptions 1.1, 1.2, une rotation de 180° par période de lunaison, en d'autres termes deux lunaisons par cycle de rotation. Il est clair que l'homme du métier saura adapter cela pour d'autres agencements du disque de lune, par exemple si celui-ci comporte trois voire plus d'inscriptions.Since the mechanism is intended to be integrated in a timepiece, in particular in a mechanical watch, the drive of the

Un tel mécanisme d'indication selon la présente invention peut être décliné sous plusieurs formes d'exécution dont quelques unes seront par la suite expliquées plus en détail afin d'illustrer concrètement et à titre d'exemple la disposition générale mentionnée au paragraphe précédent. A côté de plusieurs paramètres et d'autres détails qui peuvent être variés, ces formes d'exécution du mécanisme se distinguent notamment, d'une part, en ce qui concerne l'axe de rotation dudit voire desdits disques d'occultation 2 qui peuvent être agencés concentriquement voire non-concentriquement par rapport à l'axe de rotation du disque de lune 1, et, d'autre part, en ce qui concerne le nombre des disques d'occultation 2 qui peut être au nombre d'un, de deux voire de plusieurs. A toute évidence, la forme des disques d'occultation 2 sera choisie en conséquence.Such an indication mechanism according to the present invention can be declined in several embodiments, some of which will be subsequently explained in more detail in order to illustrate concretely and by way of example the general provision mentioned in the preceding paragraph. In addition to several parameters and other details that can be varied, these embodiments of the mechanism are distinguished, in particular, firstly with respect to the axis of rotation of said or even occultation discs 2 which can be arranged concentrically or non-concentrically with respect to the axis of rotation of the

) Il reste à constater que, évidemment, bien d'autres formes d'exécution équivalentes, non illustrées aux figures, d'un mécanisme d'indication des phases de la lune selon la présente invention peuvent être imaginées, par exemple en variant la position du voire des disques d'occultation 2.1, 2.2, notamment en y ajoutant encore un autre niveau à l'aide d'un troisième disque d'occultation, en modifiant la forme, l'agencement ou le sens de rotation du voire des disques d'occultation 2.1, 2.2 et/ou du disque de lune 1, en modifiant le guichet 3.1 formé dans le cadran 3 afin d'adapter le mécanisme par exemple pour l'affichage de phases de la lune pour l'hémisphère sud au lieu de les afficher pour l'hémisphère nord tel qu'illustré au figures, ou en modifiant le rouage d'entraînement 4, notamment la denture des roues de programme ou des pignons correspondants, ceci sans pour autant que le fonctionnement global ou le résultat en terme d'affichage diffèrent substantiellement par rapport à ce qui a été divulgué ci-dessus. Toutes ces formes d'exécution sont en fait, sans qu'il soit possible de les décrire toutes ici en détail, à la portée de l'homme du métier disposant de l'instruction technique selon la présente description.It remains to be seen that, obviously, many other equivalent embodiments, not illustrated in the figures, of a mechanism for indicating the phases of the moon according to the present invention can be imagined, for example by varying the position or even occultation discs 2.1, 2.2, in particular by adding another level using a third occulting disc, by modifying the shape, the arrangement or the direction of rotation of the discs or discs. occultation 2.1, 2.2 and / or
Ainsi, il est clair qu'un mécanisme d'indication comportant les caractéristiques mentionnées ci-dessus selon la présente invention présente l'avantage important de pouvoir afficher de manière réaliste toutes les phases différentes et principales de la lunaison, c'est-à-dire d'afficher à tout moment de manière plus réelle la partie visible sur terre de la surface de la lune illuminée par le soleil. De plus, un tel mécanisme dispose d'une grande flexibilité du fait qu'il peut être décliné sous plusieurs variantes en fonction des exigences techniques ou esthétiques. Un mécanisme d'indication selon la présente invention peut coopérer de manière conventionnelle avec les autres parties de la pièce d'horlogerie dans laquelle il est destiné à être intégré, notamment avec son mouvement de base, de sorte que le mécanisme peut facilement être intégré dans des pièces d'horlogerie existantes sans nécessiter trop d'ajustement voire une ré-conception importante de ces pièces. Par ailleurs, ces avantages sont obtenus sans pour autant trop augmenter la complexité, le volume occupé, voire le coût de production du mécanisme. Finalement, le mécanisme selon la présente invention est idéalement adapté à être mis en valeur visuellement sur le cadran de la pièce d'horlogerie, contribuant ainsi de manière importante à l'esthétique d'une telle pièce d'horlogerie.Thus, it is clear that an indicating mechanism having the features mentioned above according to the present invention has the important advantage of being able to realistically display all the phases different and main of the lunation, that is to say to display at any time in a more real way the visible part on earth of the surface of the moon illuminated by the sun. In addition, such a mechanism has great flexibility because it can be declined in several variants depending on the technical or aesthetic requirements. An indication mechanism according to the present invention can cooperate in a conventional manner with the other parts of the timepiece in which it is intended to be integrated, in particular with its basic movement, so that the mechanism can easily be integrated into existing timepieces without requiring too much adjustment or a major re-design of these parts. Moreover, these advantages are obtained without increasing the complexity, the volume occupied or the production cost of the mechanism. Finally, the mechanism according to the present invention is ideally suited to be highlighted visually on the dial of the timepiece, thus contributing significantly to the aesthetics of such a timepiece.
Au vu de la description détaillée figurant ci-dessus, il est clair que la présente invention englobe également une pièce d'horlogerie, notamment une montre mécanique, qui comprend un mécanisme d'indication des phases de la lune selon l'une de ses formes d'exécution, ledit disque de lune 1 étant normalement entraîné à raison d'un pas par jour par le mouvement de base de ladite pièce d'horlogerie.In view of the detailed description above, it is clear that the present invention also includes a timepiece, including a mechanical watch, which comprises a mechanism for indicating the phases of the moon according to one of its forms execution, said
