Description

Domaine technique de l'inventionTechnical field of the invention

Cette demande se rapporte au domaine technique général des mouvements d'horlogerie et des mécanismes d'indications qui leur sont associés, utilisés notamment dans l'horlogerie mécanique.This application relates to the general technical field of watch movements and the mechanisms of indications associated with them, used in particular in mechanical watchmaking.

La présente invention concerne plus particulièrement un mouvement d'horlogerie comprenant un organe moteur, un organe régulateur et un mécanisme d'indication comprenant un premier cadran pour l'indication d'une première information temporelle et un deuxième cadran pour l'indication d'une deuxième information temporelle. Ce premier cadran dans le mécanisme peut notamment porter l'indication des heures pendant que le deuxième cadran porte l'indication des minutes.The present invention more particularly relates to a clockwork comprising a drive member, a regulating member and an indication mechanism comprising a first dial for the indication of a first time information and a second dial for the indication of a second time information. This first dial in the mechanism may include the indication of hours while the second dial carries the indication of minutes.

Description de l'état de la techniqueDescription of the state of the art

Il est connu d'utiliser plusieurs types de mécanismes d'indication d'information temporelle dans l'horlogerie. Un mécanisme classique est le mécanisme à aiguilles, qui consiste généralement en une première aiguille pour l'indication des heures et une deuxième aiguille pour l'indication des minutes. Ces aiguilles sont généralement formées d'une pièce de métal ou d'un autre matériau léger (p.ex. en aluminium ou un autre métal léger) et elles sont entrainées en rotation au-dessus d'un seul cadran contenant à la fois les indications des heures et les indications des minutes par un arbre qui est typiquement situé au centre de la montre.It is known to use several types of temporal information indication mechanisms in the watch industry. A conventional mechanism is the needle mechanism, which generally consists of a first hand for the indication of the hours and a second hand for the indication of the minutes. These needles are usually formed of a piece of metal or other light material (eg aluminum or other light metal) and are rotated over a single dial containing both indications of the hours and the indications of the minutes by a tree which is typically located at the center of the watch.

Il est également bien connu d'utiliser une troisième aiguille pour l'indication des secondes. Cette troisième aiguille peut être également située au centre de la montre, mais elle peut également être entraînée en rotation autour d'un axe qui ne coïncide pas avec l'axe central de la montre. On connaît notamment des solutions dans lesquelles l'axe de l'aiguille des secondes est situé entre l'axe central et l'indication de six heures (typiquement du côté inférieur du cadran). Dans ce cas, le cadran peut également porter les indications des secondes.It is also well known to use a third hand for indicating seconds. This third needle can also be located in the center of the watch, but it can also be rotated about an axis that does not coincide with the central axis of the watch. Solutions are known in particular in which the axis of the second hand is situated between the central axis and the six-hour indication (typically on the bottom of the dial). In this case, the dial may also carry the seconds indications.

Un autre mécanisme d'indication bien connu dans l'état de la technique est le mécanisme à guichets. Dans les montres à guichets, le cadran est pourvu d'ouvertures sous lesquelles apparaissent les indications temporelles, par exemple les heures, les minutes et les secondes. Ces indications sont typiquement portées par un disque ou un plateau qui peut être déplacé d'une manière appropriée au-dessous du cadran. Cependant, ce type de mécanisme d'indication est plutôt utilisé pour l'indication des quantièmes en combinaison avec le mécanisme à aiguilles.Another well-known indication mechanism in the state of the art is the wicket mechanism. In watch windows, the dial is provided with openings under which appear the time indications, for example hours, minutes and seconds. These indications are typically carried by a disc or tray that can be moved appropriately below the dial. However, this type of indication mechanism is rather used for the indication of the dates in combination with the needle mechanism.

Récemment, d'autres mécanismes d'indication d'information temporelle plus modernes ont été développés. Un exemple d'un tel mécanisme d'indication temporelle est décrit dans le document EP 1 150 184 . Il est implémenté notamment dans la gamme de produits intitulée « Freak », commercialisée par la société « Manufacture et fabrique de montres et chronomètres Ulysse Nardin Le Locle SA ».Recently, other more modern time information indication mechanisms have been developed. An example of such a temporal indication mechanism is described in the document EP 1 150 184 . It is implemented in particular in the range of products entitled "Freak", marketed by the company "Manufacture and manufactures watches and chronometers Ulysse Nardin Le Locle SA".

Ce mécanisme d'indication indique les heures à l'aide d'un index solidaire du barillet qui délivre la force motrice à l'organe régulateur de la montre. A cette fin, le barillet est dimensionné pour tourner à raison d'un douzième de tour par heure. En même temps, le barillet entraine indirectement en rotation un pont qui porte une partie du rouage de finissage, l'échappement et l'organe régulateur de la montre. Ce pont tournant est dimensionné pour tourner à raison d'un tour par heure et c'est précisément ce pont tournant qui indique les minutes.This indicating mechanism indicates the hours with the aid of an index integral with the barrel which delivers the driving force to the regulating organ of the watch. To this end, the barrel is sized to rotate at a rate of one twelfth of an hour. At the same time, the barrel indirectly drives in rotation a bridge which carries part of the finishing train, the escapement and the regulating organ of the watch. This rotating bridge is sized to rotate at a rate of one turn per hour and it is precisely this rotating bridge that indicates the minutes.

Le principal désavantage de ce type de mécanisme d'indication consiste en ce que, plusieurs fois pendant un tour entier du barillet, l'index qui sert d'indication des heures n'est pas visible du côté de la glace, notamment quand le pont tournant est aligné avec cet index et le recouvre complètement. Même si la lecture de l'heure par déduction et l'expérience reste possible dans ces cas, elle présente néanmoins l'inconvénient que la lecture n'est pas tout à fait intuitive et qu'elle peut être difficile pour certains porteurs de la montre (p.ex. les personnes âgées).The main disadvantage of this type of indicating mechanism is that, several times during an entire turn of the barrel, the index which serves as an indication of the hours is not visible on the ice side, especially when the bridge rotating is aligned with this index and covers it completely. Even if reading the time by inference and experience remains possible in these cases, it nevertheless has the disadvantage that the reading is not quite intuitive and that it can be difficult for some wearers of the watch (eg the elderly).

Dans le brevet suisse CH 701 830 B1 , il est décrit un mécanisme d'affichage d'un mouvement horloger. Ce mécanisme d'affichage comprend un index et un disque qui sont tous deux mobiles, en ayant le même axe de rotation. L'index mobile indique une première information horaire, telle que les heures, sur un cadran fixe, ainsi qu'une deuxième information horaire, telles que les minutes, sur le disque mobile qui est entraîné de manière à posséder une vitesse de rotation par rapport à l'index.In the Swiss patent CH 701 830 B1 a mechanism for displaying a watch movement is described. This display mechanism comprises an index and a disc which are both movable, having the same axis of rotation. The moving index indicates a first time information, such as the hours, on a fixed dial, as well as a second time information, such as minutes, on the moving disk which is driven so as to have a rotation speed relative to to the index.

Exposé sommaire de l'inventionSummary of the invention

L'objet de la présente invention vise donc à pallier les inconvénients précités et à fournir un mouvement d'horlogerie ayant un mécanisme amélioré d'indication d'information temporelle, notamment en combinaison avec une nouvelle conception du mouvement d'horlogerie.The object of the present invention is therefore to overcome the aforementioned drawbacks and to provide a watch movement having an improved mechanism for indicating time information, in particular in combination with a new design of the watch movement.

Un autre objet de la présente invention vise à fournir un mouvement d'horlogerie dont un mécanisme d'indication d'information permet une lecture d'information temporelle plus intuitive et facile que la lecture d'information qui est indiquée à l'aide des mécanismes existants, abstraction faite du mécanisme d'affichage décrit dans le brevet suisse CH 701 830 B1 précité.Another object of the present invention is to provide a clockwork movement whose information-indicating mechanism makes it possible to read time information that is more intuitive and easier than the reading of information that is indicated using the mechanisms existing, irrespective of the display mechanism described in the Swiss patent CH 701 830 B1 supra.

Un autre objet de la présente invention vise à fournir un mouvement d'horlogerie ayant un mécanisme d'indication grâce auquel les montres peuvent être munies d'un aspect avant-gardiste et moderne.Another object of the present invention is to provide a watch movement having an indicating mechanism by which the watches can be provided with an avant-garde and modern appearance.

Les objets assignés à l'invention sont atteints à l'aide d'un mouvement d'horlogerie tel que défini dans la revendication indépendante 1.The objects assigned to the invention are achieved by means of a clockwork movement as defined in independent claim 1.

Aussi, le déplacement de l'organe moteur, qui est nécessaire pour l'entretien de l'organe régulateur de la montre, peut être directement traduit dans le déplacement de l'index, sans qu'un système d'entraînement séparé ne soit nécessaire juste pour le déplacement de l'index. Cette solution résulte donc en un mécanisme simple et facile à fabriquer. De même, grâce à la présente invention aucune pièce supplémentaire ne doit être prévue pour le déplacement de l'index. Il en résulte un mécanisme encore plus simple et plus facile à fabriquer.Also, the displacement of the drive member, which is necessary for the maintenance of the regulating member of the watch, can be directly translated into the movement of the index, without the need for a separate drive system. just for moving the index. This solution therefore results in a simple and easy to manufacture mechanism. Likewise, thanks to the present invention no additional piece must be provided for the movement of the index. This results in an even simpler and easier mechanism to manufacture.

Le mouvement d'horlogerie conforme à la présente invention présente l'avantage qu'un index unique en combinaison avec plusieurs cadrans séparés peut être utilisé pour l'indication de plusieurs informations temporelles. Par ce fait, les problèmes liés à la lecture des informations temporelles avec le mécanisme « Freak » décrit plus haut sont résolus sans que l'aspect moderne de la montre soit compromis. Selon un autre mode de réalisation de la présente invention, le premier cadran est monté de sorte qu'il est immobile par rapport à la platine et le deuxième cadran est monté de sorte qu'il est mobile par rapport à la platine. Grâce à une telle solution, un seul cadran doit être déplacé pour l'indication des première et deuxième informations temporelles. De nouveau, cela rend le mécanisme proposé plus simple et plus facile à fabriquer par rapport à un mécanisme qui nécessiterait deux systèmes d'entraînement des cadrans.The clockwork according to the present invention has the advantage that a single index in combination with several separate dials can be used for the indication of several temporal information. By this fact, the problems related to the reading of the temporal information with the "Freak" mechanism described above are solved without the modern aspect of the watch being compromised. According to another embodiment of the present invention, the first dial is mounted so that it is stationary relative to the plate and the second dial is mounted so that it is movable relative to the plate. With such a solution, a single dial must be moved for the indication of the first and second time information. Again, this makes the proposed mechanism simpler and easier to manufacture than a mechanism that would require two dial drive systems.

Selon un autre exemple de réalisation conforme à l'invention, l'organe moteur est un barillet. Sous le terme barillet, on comprend une boîte cylindrique fermée ou non par un couvercle avec une roue formée d'un disque circulaire denté qui contient le ressort moteur et un arbre. L'avantage de cet exemple de réalisation réside dans le fait que l'index est directement entrainé par le barillet du mouvement. Par ce fait, aucune pièce intermédiaire n'est nécessaire entre la source de force motrice et l'index indicateur. Ainsi, le mouvement du barillet (qui suit forcément une règle temporelle prédéfinie, induite par l'organe régulateur de la montre et les rapports d'engrenage) peut être utilisé pour l'indication de l'information temporelle correspondante.
Selon un autre exemple de réalisation conforme à l'invention, le premier cadran a la forme d'un disque annulaire concentrique à l'axe central du mouvement. L'avantage de cet exemple de réalisation réside dans le fait que le mouvement rotatif d'un index qui se déplace autour de l'axe central peut facilement être utilisé pour l'indication de la première information temporelle. Typiquement, le disque est dimensionné pour que la distance radiale entre l'index et le centre du mouvement soit plus petite que le diamètre intérieur du disque, bien que d'autres dimensions sont également possibles.According to another exemplary embodiment according to the invention, the driving member is a barrel. Under the term barrel, there is understood a cylindrical box closed or not by a cover with a wheel formed of a circular toothed disc which contains the mainspring and a shaft. The advantage of this example of embodiment lies in the fact that the index is directly driven by the barrel movement. As a result, no intermediate piece is needed between the source of driving force and the indicator index. Thus, the movement of the barrel (which inevitably follows a predefined temporal rule, induced by the watch regulator and the gear ratios) can be used to indicate the corresponding time information.
According to another exemplary embodiment according to the invention, the first dial has the shape of an annular disc concentric with the central axis of the movement. The advantage of this exemplary embodiment lies in the fact that the rotary movement of an index which moves around the central axis can easily be used for the indication of the first time information. Typically, the disk is sized so that the radial distance between the index and the center of the movement is smaller than the inside diameter of the disk, although other dimensions are also possible.

Selon un autre exemple de réalisation conforme à l'invention, le deuxième cadran a la forme d'un disque annulaire concentrique à l'axe central du mouvement et le diamètre extérieur du deuxième cadran est plus petit que le diamètre intérieur du premier cadran. L'avantage de cet exemple de réalisation de l'invention réside notamment dans le fait que le deuxième cadran peut être complètement situé dans l'ouverture laissée par le premier cadran. Ainsi, les deux cadrans peuvent être positionnés sans se gêner mutuellement. De même, un dimensionnement approprié des premier et deuxième cadrans permet également que l'index puisse être positionné dans l'espace laissé radialement entre les deux cadrans.According to another exemplary embodiment according to the invention, the second dial has the shape of an annular disc concentric with the central axis of the movement and the outer diameter of the second dial is smaller than the inner diameter of the first dial. The advantage of this embodiment of the invention lies in the fact that the second dial can be completely located in the opening left by the first dial. Thus, both dials can be positioned without interfering with each other. Similarly, an appropriate dimensioning of the first and second dials also allows the index can be positioned in the space left radially between the two dials.

Selon un autre exemple de réalisation conforme à l'invention, l'organe régulateur est monté dans l'ouverture du deuxième cadran. L'avantage de cet exemple de réalisation est, parmi d'autres choses, que la visibilité de l'organe régulateur permet de mettre en évidence le mouvement de la montre qui utilise un tel mécanisme d'indication.According to another exemplary embodiment according to the invention, the regulating member is mounted in the opening of the second dial. The advantage of this exemplary embodiment is, among other things, that the visibility of the regulating member makes it possible to highlight the movement of the watch which uses such an indication mechanism.

Selon un autre exemple de réalisation conforme à l'invention, le deuxième cadran a la forme d'un plateau circulaire concentrique à l'axe central du mouvement. Cet exemple de réalisation de l'invention présente notamment l'avantage qu'un deuxième cadran en forme d'un plateau circulaire permet de se priver de l'ouverture centrale qui est présente dans le cas d'un deuxième cadran en forme d'un disque annulaire. Cet exemple de réalisation est donc particulièrement avantageux si le mouvement horloger ne doit pas être visible depuis l'extérieur.According to another exemplary embodiment according to the invention, the second dial has the shape of a circular plate concentric with the central axis of the movement. This exemplary embodiment of the invention has the particular advantage that a second dial in the form of a circular plate makes it possible to deprive itself of the central opening which is present in the case of a second dial. in the form of an annular disc. This exemplary embodiment is therefore particularly advantageous if the watch movement is not visible from the outside.

Avantageusement, le diamètre extérieur du deuxième cadran peut être plus petit que le diamètre intérieur du premier cadran. Cette solution est la plus intuitive et elle reprend tous les avantages du mode de réalisation selon lequel le deuxième cadran est réalisé en forme d'un disque annulaire. D'autre part, le deuxième cadran peut également être fabriqué en un matériau transparent. Dans ce cas, le deuxième cadran ne doit pas forcément avoir son diamètre extérieur plus petit que le diamètre intérieur du premier cadran pour que l'indication des deux informations temporelles soit possible et un autre aspect esthétique peut être atteint sans qu'une modification de la conception du mécanisme ne soit nécessaire.Advantageously, the outer diameter of the second dial may be smaller than the inside diameter of the first dial. This solution is the most intuitive and it takes all the advantages of the embodiment according to which the second dial is made in the form of an annular disc. On the other hand, the second dial can also be made of a transparent material. In this case, the second dial does not have to have its outside diameter smaller than the inside diameter of the first dial so that the indication of the two temporal information is possible and another aesthetic appearance can be achieved without a modification of the Mechanism design is needed.

Dans un autre mode de réalisation de l'invention, le deuxième cadran est fabriqué en un matériau transparent. Grâce à cette caractéristique, le mécanisme d'indication conforme à l'invention peut être réalisé avec un plus grand degré de liberté. Effectivement, la transparence du deuxième cadran permet son dimensionnement plus flexible. Il est notamment possible de réaliser un mécanisme d'indication avec un deuxième cadran dont le diamètre extérieur est égal ou même plus grand que le diamètre intérieur du premier cadran, sans que la fonctionnalité et les avantages du mécanisme d'indication ne soient compromis.In another embodiment of the invention, the second dial is made of a transparent material. With this feature, the indication mechanism according to the invention can be realized with a greater degree of freedom. Indeed, the transparency of the second dial allows its dimensioning more flexible. In particular, it is possible to produce an indication mechanism with a second dial whose outer diameter is equal to or even greater than the inside diameter of the first dial, without the functionality and the advantages of the indicating mechanism being compromised.

L'organe régulateur peut notamment être un balancier-spiral classique, mais également un tourbillon. La solution avec un tourbillon est conceptionnellement évidemment plus complexe que la solution avec un balancier-spiral classique, mais elle présente également une attraction technique plus élevée. En particulier, le tourbillon peut aussi porter un deuxième index pour l'indication d'une troisième information temporelle (p.ex. l'indication des secondes). L'avantage de ces derniers modes de réalisation réside notamment dans le fait que le même mécanisme permet de varier la conception de l'indication temporelle en fonction des besoins particuliers, sans que la construction de base ne soit modifiée.The regulating member may in particular be a conventional balance spring, but also a tourbillon. The solution with a tourbillon is obviously obviously more complex than the solution with a conventional balance-spring, but it also has a higher technical attraction. In particular, the vortex may also carry a second index for the indication of a third time information (eg the indication of seconds). The advantage of these latter embodiments lies notably in the fact that the same mechanism makes it possible to vary the design of the time indication according to the particular needs, without the basic construction being modified.

Notablement, le mouvement d'horlogerie peut comprendre un rouage relié cinématiquement à l'organe moteur pour le déplacement du deuxième cadran. De cette manière, les déplacements angulaires du deuxième cadran peuvent être contrôlés de manière voulue.Notably, the clockwork movement may comprise a gear train kinematically connected to the motor unit for moving the second dial. In this way, the angular displacements of the second dial can be controlled in a desired manner.

Selon un exemple notable de réalisation conforme à l'invention, le premier cadran porte l'indication des heures et le deuxième cadran porte l'indication des minutes.According to a notable example of embodiment according to the invention, the first dial bears the indication of the hours and the second dial carries the indication of the minutes.

Exposé détaillé des modes de réalisation de l'inventionDETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

Les éléments structurellement et fonctionnellement identiques et présents dans des figures distinctes sont affectés d'une seule et même référence.The structurally and functionally identical elements present in separate figures are assigned a single reference.

Les figures 1 et 2 illustrent une montre avec un exemple de réalisation d'un mécanisme d'indication 1 d'un mouvement d'horlogerie conforme à l'invention. La montre illustrée comporte notamment un cercle 5 duquel est solidaire le premier cadran 12. Ce cercle 5 comprend une surface d'appui 6, 8 et plusieurs trous taraudés 7, 9 qui permettent sa fixation à la carrure de la montre par des vis. La bague de lunette 2, 4 comprend plusieurs trous taraudés 3 permettant sa fixation au cercle 5
par des vis. La lunette 10 est contrainte axialement entre le cercle 5 et la bague de lunette 2, 4. Cette lunette 10 comprend un trou 11 permettant de la rendre solidaire angulairement à la lunette de carrure par l'intermédiaire d'une goupille ou d'une clavette.The figures 1 and 2 illustrate a watch with an exemplary embodiment of an indication mechanism 1 of a watch movement according to the invention. The illustrated watch comprises in particular a circle 5 which is secured to the first dial 12. This circle 5 comprises a bearing surface 6, 8 and several threaded holes 7, 9 which allow its attachment to the middle part of the watch by screws. The bezel ring 2, 4 comprises several threaded holes 3 allowing its attachment to the circle 5
by screws. The bezel 10 is axially constrained between the circle 5 and the bezel ring 2, 4. This bezel 10 comprises a hole 11 for making it angularly integral with the middle case bezel by means of a pin or a key .

Le mécanisme d'indication 1 de la montre sur les figures 1 et 2 comprend un premier cadran 12 et un deuxième cadran 17 qui portent respectivement les indications d'une première et d'une deuxième information temporelle. Dans les figures 1 et 2, le premier cadran 12 porte les indications des heures pendant que le deuxième cadran 17 porte les indications des minutes. Bien entendu, il serait également possible de construire une montre dans laquelle les deux cadrans 12 et 17 porteraient des autres indications temporelles, avec des adaptations correspondantes au niveau du mécanisme 1.The mechanism of indication 1 of the watch on the figures 1 and 2 comprises a first dial 12 and a second dial 17 which respectively bear the indications of a first and a second time information. In the figures 1 and 2 the first dial 12 carries the hours indications while the second dial 17 indicates the minutes. Of course, it would also be possible to construct a watch in which the two dials 12 and 17 would bear other time indications, with corresponding adaptations at the level of the mechanism 1.

Dans les figures 1 et 2, les chiffres arabes sont utilisés comme indications et ils sont disposés à la fois sur le premier cadran 12 et le deuxième cadran 17. Il est néanmoins évident que d'autres moyens d'indication sont également possibles, notamment des chiffres romains, des divisions, etc. Dans l'exemple du mécanisme 1 illustré dans les figures 1 et 2, le deuxième cadran 17 comprend une combinaison de chiffres arabes et de traits pour l'indication des minutes. Les chiffres ou les autres moyens d'indication peuvent par exemple être collés sur les cadrans 12, 17, gravés dans le matériau des cadrans 12, 17 ou représentés d'une autre manière appropriée.In the figures 1 and 2 , the Arabic numerals are used as indications and they are arranged on both the first dial 12 and the second dial 17. It is nevertheless obvious that other means of indication are also possible, including Roman numerals, divisions, etc. In the example of mechanism 1 illustrated in figures 1 and 2 , the second dial 17 comprises a combination of Arabic numerals and lines for the indication of the minutes. Numbers or other means of indication may for example be glued on the dials 12, 17, engraved in the material of the dials 12, 17 or shown in another appropriate manner.

Le premier cadran 12 est monté de sorte qu'il est immobile par rapport au cercle 5. Le premier cadran 12 peut notamment être fixé directement sur la platine du mouvement, mais une réalisation de l'invention dans laquelle le premier cadran 12 est fixé sur un élément intermédiaire est également possible. De même, il peut également être envisagé de fixer le premier cadran 12 par rapport à la carrure ou un autre élément du boîtier 2, si le premier cadran 12 reste immobile par rapport à la platine du mouvement.The first dial 12 is mounted so that it is immobile with respect to the circle 5. The first dial 12 may in particular be fixed directly on the stage of the movement, but an embodiment of the invention in which the first dial 12 is fixed on an intermediate element is also possible. Similarly, it may also be envisaged to fix the first dial 12 relative to the middle part or another element of the housing 2, if the first dial 12 remains stationary relative to the platen of the movement.

Dans les figures 1 et 2, le premier cadran 12 a la forme d'un disque annulaire qui est concentrique à l'axe central du mouvement. Il est cependant également envisageable d'avoir un premier cadran 12 en forme d'un plateau circulaire qui est au moins partiellement fabriqué en un matériau transparent de manière qu'il ne cache pas la partie centrale de la montre.In the figures 1 and 2 the first dial 12 has the shape of an annular disc which is concentric with the central axis of the movement. However, it is also possible to have a first dial 12 in the form of a tray circular which is at least partially made of a transparent material so that it does not hide the central part of the watch.

Le numéro de référence 15 dans les figures 1 et 2 représente un index qui est mobile par rapport au premier cadran 12 et qui indique la première information temporelle (dans l'exemple de la figure 1 les heures) en combinaison avec les indications correspondantes sur le premier cadran 12. A cette fin, les déplacements de l'index 15 sont induits par un organe moteur 14 du mouvement. Le déplacement de l'index 15 dans l'exemple illustré dans les figures 1 et 2 correspond à une rotation autour de l'axe central du mouvement.Reference number 15 in the figures 1 and 2 represents an index which is movable with respect to the first dial 12 and which indicates the first time information (in the example of the figure 1 the hours) in combination with the corresponding indications on the first dial 12. To this end, the movements of the index 15 are induced by a motor member 14 of the movement. The displacement of the index 15 in the example illustrated in the figures 1 and 2 corresponds to a rotation around the central axis of the movement.

L'organe moteur 14 du mouvement peut notamment être un barillet, avec un ressort moteur. Un barillet est généralement constitué d'une roue formée d'un disque circulaire denté et d'une boîte cylindrique fermée par un couvercle. Le barillet peut en outre tourner librement sur un arbre qui est normalement situé au centre du barillet. Il contient également le ressort moteur qui est accroché au barillet par sa spire extérieure et à l'arbre par sa spire intérieure. Il est cependant clair que le barillet peut être remplacé par n'importe quel autre élément équivalent, sans que l'idée principale de cette invention ne soit abandonnée.The motor member 14 of the movement may in particular be a barrel, with a motor spring. A barrel generally consists of a wheel formed of a circular toothed disc and a cylindrical box closed by a cover. The barrel can also rotate freely on a shaft which is normally located in the center of the barrel. It also contains the mainspring which is attached to the barrel by its outer turn and to the shaft by its inner coil. It is however clear that the barrel can be replaced by any other equivalent element, without the main idea of this invention being abandoned.

Dans l'exemple des figures 1 et 2, l'index 15 est solidaire du barillet 14 (notamment, il peut s'agir d'une indication directement gravée, décalquée ou collée sur le barillet 14), mais il est également envisageable de réaliser cette connexion d'une manière différente. Par exemple, l'index 15 peut être réalisé sur un plateau circulaire attaché au barillet 14 à l'aide d'un mécanisme grâce auquel le plateau peut tourner simultanément avec le barillet 14. De même, il serait également possible de réaliser cet index 15 comme une pièce distincte et de mettre à disposition un train cinématique, entrainé par le barillet 14, pour le déplacement de l'index 15.In the example of figures 1 and 2 , the index 15 is integral with the barrel 14 (in particular, it may be an indication directly engraved, traced or glued on the barrel 14), but it is also conceivable to make this connection in a different manner. For example, the index 15 can be made on a circular plate attached to the barrel 14 by means of a mechanism by which the plate can rotate simultaneously with the barrel 14. Similarly, it would also be possible to make this index 15 as a separate piece and to provide a kinematic train, driven by the barrel 14, for the movement of the index 15.

De préférence, le barillet 14 est dimensionné et agencé pour se déplacer à une vitesse de rotation d'un tour en douze heures. De cette manière, l'index 15 qui se déplace à la même vitesse peut être directement utilisé pour indiquer les heures sur le premier cadran 12. Bien entendu, il serait aussi possible d'utiliser une autre vitesse de déplacement du barillet 14, et de modifier soit la vitesse de déplacement de l'index 15 à l'aide d'un engrenage ou un autre mécanisme de transmission de vitesse approprié, soit la répartition des indications des heures sur le premier cadran 12.Preferably, the barrel 14 is sized and arranged to move at a rotational speed of one revolution in twelve hours. In this way, the index 15 which moves at the same speed can be directly used to indicate the hours on the first dial 12. Of course, it would also be possible to use another speed of movement of the barrel 14, and change either the speed of movement of the index 15 with a gear or other suitable gear transmission mechanism, ie the distribution of the hour indications on the first dial 12.

Contrairement au premier cadran 12, le deuxième cadran 17 est monté de sorte qu'il est mobile par rapport à la platine du mouvement. Notamment, le deuxième cadran 17 peut effectuer un mouvement rotationnel autour de l'axe central du mouvement de la montre. Typiquement, ce deuxième cadran 17 possède la forme d'un disque annulaire qui est concentrique à cet axe central du mouvement et son diamètre extérieur est plus petit que le diamètre intérieur du premier cadran 12. D'autres formes et dimensions du deuxième cadran 17 sont néanmoins également possibles. En particulier, le deuxième cadran 17 peut aussi avoir la forme d'un plateau circulaire qui est également disposé pour être concentrique à l'axe central du mouvement. Dans ce cas, il peut notamment être fabriqué en un matériau transparent, même si un deuxième cadran 17 en un matériau opaque est également imaginable.Unlike the first dial 12, the second dial 17 is mounted so that it is movable relative to the platen of the movement. In particular, the second dial 17 can rotate about the central axis of the movement of the watch. Typically, this second dial 17 has the shape of an annular disc which is concentric with this central axis of the movement and its outer diameter is smaller than the inside diameter of the first dial 12. Other shapes and dimensions of the second dial 17 are nevertheless also possible. In particular, the second dial 17 may also have the shape of a circular plate which is also arranged to be concentric with the central axis of the movement. In this case, it can in particular be made of a transparent material, even if a second dial 17 in an opaque material is also imaginable.

Le deuxième cadran 17 est entrainé en rotation à l'aide d'un train cinématique. La figure 3, avec une vue de coupe de la montre représentée dans les figures 1 et 2, montre les éléments les plus importants de ce train cinématique. En l'occurrence, il s'agit d'un train planétaire simple, même si d'autres mécanismes d'entrainement du deuxième cadran 17 sont tout à fait possibles.The second dial 17 is rotated using a kinematic train. The figure 3 , with a cutaway view of the watch shown in the figures 1 and 2 , shows the most important elements of this kinematic train. In this case, it is a simple planetary gear, even if other drive mechanisms of the second dial 17 are quite possible.

Ce train cinématique est formé par le châssis 25 qui est constitué du tambour du barillet 14, le satellite 26, la couronne (qui n'est pas représentée en coupe, mais qui est fixe par rapport à la platine du mouvement) et le pignon solaire 24. Un mouvement satellitaire simple est imposé au satellite 26 par la couronne et la rotation du châssis 25 (ou du barillet 14). Le satellite 26 fait tourner le pignon solaire 24 duquel est solidaire une cage qui comporte l'oscillateur 22, l'échappement 23 et plusieurs mobiles (en partie non représentés dans la coupe parce qu'ils sont cachés par l'oscillateur 22). Le dernier de ces mobiles engrène avec la roue à denture intérieure 28 qui est également fixe par rapport à la platine du mouvement. Le fonctionnement exact du train cinématique et des éléments individuels de ce train est compréhensible pour tout homme du métier dans le domaine de l'horlogerie.This kinematic train is formed by the frame 25 which is constituted by the drum of the barrel 14, the satellite 26, the crown (which is not shown in section, but which is fixed with respect to the plate of the movement) and the sun gear 24. A simple satellite movement is imposed on the satellite 26 by the ring gear and the rotation of the frame 25 (or the barrel 14). The satellite 26 rotates the sun gear 24 which is secured to a cage which comprises the oscillator 22, the escapement 23 and several mobiles (partly not shown in the section because they are hidden by the oscillator 22). The last of these mobiles meshes with the internal gear 28 which is also fixed relative to the platen of the movement. The exact operation of the kinematic train and individual elements of this train is understandable for anyone skilled in the field of watchmaking.

L'entrainement du deuxième cadran 17 peut être organisé de manière à ce qu'il se déplace à une vitesse prédéterminée par rapport à la platine du mouvement, et ainsi par rapport au premier cadran 12, et par rapport au barillet 14. Il est également possible de faire tourner le deuxième cadran 12 et le barillet 14 dans le même sens (notamment le sens des aiguilles d'une montre) ou bien de faire tourner le deuxième cadran 17 dans le sens opposé.The drive of the second dial 17 can be organized so that it moves at a predetermined speed with respect to the platen of the movement, and thus with respect to the first dial 12, and with respect to the barrel 14. It is also possible to turn the second dial 12 and the barrel 14 in the same direction (in particular the clockwise) or to rotate the second dial 17 in the opposite direction.

Grâce à cet arrangement du premier cadran 12, du deuxième cadran 17 et de l'index 15, celui-ci peut simultanément indiquer la première et la deuxième information temporelle, à savoir les heures sur le premier cadran 12 et les minutes sur le deuxième cadran 17. Comme représenté dans les figures 1 et 2, l'index 15 indique 10h30 : la partie de l'index 15 opposée au premier cadran 12 se trouve exactement au milieu entre les indications de 10 heures et de 11 heures, pendant qu'en même temps, la partie de l'index 15 opposée au deuxième cadran 17 est alignée avec l'indication des 30 minutes sur le deuxième cadran 17.With this arrangement of the first dial 12, the second dial 17 and the index 15, it can simultaneously indicate the first and the second time information, namely the hours on the first dial 12 and the minutes on the second dial. 17. As represented in the figures 1 and 2 the index 15 indicates 10:30: the part of the index 15 opposite the first dial 12 is exactly in the middle between the indications of 10 hours and 11 hours, while at the same time, the part of the index 15 opposite the second dial 17 is aligned with the indication of 30 minutes on the second dial 17.

La lecture de l'information temporelle (heures-minutes) avec le mécanisme d'indication 1 est donc très intuitive et simple. En outre, toutes les indications sur le premier cadran 12 et le deuxième cadran 17 sont toujours visibles de sorte que la lecture reste toujours possible.The reading of the time information (hours-minutes) with the indication mechanism 1 is therefore very intuitive and simple. In addition, all indications on the first dial 12 and the second dial 17 are always visible so that reading is still possible.

Egalement illustré dans les figures 1 et 2 est l'organe régulateur du mouvement 20, représenté par un balancier-spiral de type connu dans la technique. Néanmoins, il est absolument possible de remplacer le balancier-spiral par un autre organe régulateur approprié. En particulier, il est tout à fait imaginable d'utiliser un tourbillon au lieu du balancier-spiral.Also illustrated in figures 1 and 2 is the regulating member of the movement 20, represented by a sprung balance of the type known in the art. Nevertheless, it is absolutely possible to replace the sprung balance with another suitable regulating member. In particular, it is quite conceivable to use a vortex instead of the sprung balance.

Un tourbillon est un dispositif, bien connu dans le domaine, destiné essentiellement à sensiblement annuler les écarts de marche dans les positions verticales de la montre. A cette fin, le tourbillon comprend typiquement une cage mobile qui porte tous les organes de l'échappement et, en son centre l'organe régulateur. Le pignon d'échappement tourne autour de la roue des secondes qui est fixe. La cage peut faire un tour par minute et elle réduit ainsi les écarts de marche dans les positions verticales. En plus de ces aspects techniques, un tourbillon possède également un aspect esthétique qui fait que les tourbillons sont actuellement utilisés également à cause de cette propriété.A vortex is a device, well known in the art, intended essentially to substantially cancel the gaits in the vertical positions of the watch. For this purpose, the vortex typically comprises a movable cage which carries all the organs of the exhaust and, in its center the regulating organ. The escape gear rotates around the seconds wheel which is fixed. The cage can do one revolution per minute and thus reduces the gaps in the vertical positions. In addition to these technical aspects, a tourbillon also has an aesthetic appearance that makes the vortices are currently used also because of this property.

Si un tourbillon est utilisé comme organe régulateur de la montre, il peut porter un deuxième index pour l'indication d'une troisième indication temporelle, notamment des secondes. A cette fin, la cage du tourbillon peut aussi servir comme cadran indicateur et porter les indications des secondes.If a vortex is used as a regulating member of the watch, it may carry a second index for the indication of a third time indication, especially seconds. To this end, the tourbillon cage can also serve as an indicator dial and carry the seconds indications.

Naturellement, la présente invention est sans autre sujette à de nombreuses variations quant à sa mise en oeuvre. Bien que plusieurs modes de réalisations aient été décrits, on comprend bien qu'il n'est pas concevable d'identifier de manière exhaustive tous les modes possibles. Dans ce sens, il est bien sûr envisageable de remplacer un ou plusieurs moyens décrits par un ou plusieurs moyens équivalents sans sortir du cadre de la présente invention.Naturally, the present invention is without any other subject to many variations as to its implementation. Although several embodiments have been described, it is clear that it is not conceivable to exhaustively identify all the possible modes. In this sense, it is of course conceivable to replace one or more means described by one or more equivalent means without departing from the scope of the present invention.
