L'invention concerne un mobile d'horlogerie 1, notamment pour pièces d'horlogerie compliquées, et conçu en particulier pour un tourbillon 100 d'horlogerie comportant une cage 110, ou pour un carrousel ou pour toute autre structure similaire. Si ce mobile 1, tel que décrit ci-après, est bien sûr utilisable pour d'autres complications horlogères, notamment pour des pendules ou montres mystérieuses ou similaires, il est plus précisément décrit dans ce cadre particulier d'application à un tourbillon, pour lequel il a été spécifiquement conçu, et où il apporte le plus d'avantages. L'appellation « tourbillon » dans la suite de la présente description couvre aussi bien un tourbillon qu'un carrousel.

Dans une variante particulière, le mobile 1 est monobloc.In a particular variant, the mobile 1 is monobloc.
L'invention concerne encore un bloc d'horlogerie, comportant un premier mobile comportant une première fonction horlogère, pivotant coaxialement avec au moins un deuxième mobile que comporte ce bloc. Le deuxième mobile comporte une deuxième fonction horlogère différente de la première fonction horlogère. Selon l'invention, au moins le premier mobile ou le deuxième mobile comporte un premier niveau, respectivement un deuxième niveau, qui est plein et qui est au moins partiellement transparent, de façon à permettre la visualisation de l'autre mobile.The invention also relates to a watch unit, comprising a first mobile having a first watch function, pivoting coaxially with at least a second mobile that includes this block. The second mobile has a second watch function different from the first watch function. According to the invention, at least the first mobile or the second mobile has a first level, respectively a second level, which is full and which is at least partially transparent, so as to allow viewing of the other mobile.

Un exemple d'un tel bloc concerne par exemple un mécanisme de phase de lune et d'indication jour-nuit superposées, avec un masque de transparence variable. Un tel bloc est avantageusement formé de deux mobiles pleins, dont le mobile supérieur assure un affichage jour-nuit, et comporte une partie transparente pour laisser visible un disque de lune qui lui est coaxial. Dans une autre variante, le bloc comporte un guichet mobile, sur un disque supérieur, au-dessus d'un disque de lune. Dans une autre variante encore, le bloc comporte un affichage de signes zodiacaux en superposition des représentations de la lune au sein d'un mois lunaire, ou similaire.An example of such a block is for example a superimposed moon phase and day-night indication mechanism, with a variable transparency mask. Such a block is advantageously formed of two full mobiles, whose upper mobile ensures a day-night display, and has a transparent portion to leave visible a moon disk which is coaxial. In another variant, the block comprises a mobile office, on an upper disk, above a moon disk. In yet another variant, the block includes a display of zodiacal signs superimposed representations of the moon within a lunar month, or the like.

L'invention concerne encore un mouvement 200 d'horlogerie, comportant au moins un tel tourbillon 100, ou/et au moins un tel mobile 1.The invention also relates to a

L'invention concerne encore une montre 300 compliquée comportant au moins un tel mouvement 200, ou/et au moins un tel mobile 1.The invention also relates to a
L'invention est ainsi illustrée, sur les
Dans cet exemple, la cage 110 de tourbillon est située sous la came d'équation 9 et son palpeur 10.In this example, the
En construction classique, le tourbillon est caché par une roue qui assure différentes fonctions:
- entraînement de la came par une denture extérieure ;
- pivotement de la came par un palier central ;
- affichage des mois, en général par une zone décalquée ;
- rigidité de la came.
- driving the cam by an external toothing;
- pivoting of the cam by a central bearing;
- month display, usually by a traced area;
- rigidity of the cam.
L'invention propose de remplacer la partie centrale de cette roue par un disque en saphir ou autre matière transparente, formant la planche transparente 2, laquelle laisse voir les composants situés en-dessous, en particulier la cage 110 de tourbillon dans cet exemple.The invention proposes to replace the central portion of this wheel with a sapphire disc or other transparent material, forming the
La planche transparente 2 sert de support à la came d'équation 9, qui est assemblée sur ce disque 2 par collage, ou par croissance galvanique, ou autre. Cet assemblage permet de réduire les dimensions de la came 9, car les contraintes mécaniques sur la came 9 sont en partie absorbées par le disque 2. La came 9 laisse donc une meilleure visibilité au tourbillon 100.The
Le disque 2 supporte les moyens de pivotement 3 au centre, et le report des premiers moyens d'entraînement 4 à l'extérieur permet d'éviter la présence des bras de liaison de ces éléments entre eux.The
Le disque 2 supporte avantageusement les indications et graduations 8, 80, 81, qui sont nécessaires à l'affichage lié à la fonction considérée, tout en assurant néanmoins une transparence suffisante pour bien observer le mécanisme.The
Il est ainsi possible d'affiner très fortement la came d'équation 9. La came d'équation 9 très fine, le palpeur de came 10, et les graduations 8, 80, 81, étant les seuls éléments visibles, la vue sur le tourbillon 100 est assurée. De plus l'aspect esthétique de l'invention est un avantage.It is thus possible to very strongly refine the
En somme, l'invention permet une bonne visibilité de composants situés sous d'autres composants. L'invention permet encore d'améliorer notablement la rigidité de composants très fins, notamment dans des mouvements squelettes.In short, the invention allows good visibility of components located under other components. The invention also makes it possible to significantly improve the rigidity of very fine components, especially in skeletal movements.
