In a second variant, this mechanism 100 does not include a date ring 1, and is then arranged to cooperate with such a date ring 1 with internal toothing 2 of a clockwork movement 200.

Dans l'une ou l'autre variante, le mécanisme 100 comporte un mobile d'affichage de lune 3, qui est maintenu en position par un sautoir de lune 39.In either variant, the mechanism 100 includes a moon display mobile 3, which is held in position by a moon jumper 39.

Le mécanisme 100 comporte des moyens d'entraînement 5, qui sont agencés pour être actionnés par la denture intérieure 2 lors de chaque rotation de l'anneau de quantième 1. Ces moyens d'entraînement 5 sont agencés pour entraîner le mobile d'affichage de lune 3, selon un premier pas angulaire constant, lors de chaque rotation de l'anneau de quantième 1.The mechanism 100 includes drive means 5, which are arranged to be actuated by the internal toothing 2 during each rotation of the date ring 1. These drive means 5 are arranged to drive the display mobile of moon 3, according to a first constant angular step, during each rotation of the date ring 1.

Le principe de l'invention consiste à entraîner un ensemble de leviers actionnant des roues de phase de lune et quantième. Plus particulièrement, et non limitativement, l'invention permet d'utiliser un indicateur de quantième standard (mouvement 2824-2 ETA par exemple), et de greffer un module qui est entraîné par l'indicateur quantième du mouvement de base. A noter que les deux leviers entraînant la phase de lune et le quantième sont de préférence liés par une articulation, notamment au niveau d'une goupille.The principle of the invention consists in driving a set of levers actuating the moon phase and date wheels. More particularly, and without limitation, the invention makes it possible to use a standard date indicator (movement 2824-2 ETA for example), and to graft a module which is driven by the date indicator of the basic movement. Note that the two levers driving the moon phase and the date are preferably linked by an articulation, in particular at the level of a pin.

Selon l'invention, les moyens d'entraînement 5 comportent une bascule d'entrée 50 pivotante autour d'un axe d'entrée A5. Cette bascule d'entrée 50 comporte une première extrémité 51, qui est agencée pour coopérer avec la denture intérieure 2, et une deuxième extrémité 52, qui est agencée pour coopérer en appui de poussée avec une surface d'appui 72 que comporte une bascule principale 7. Cette bascule principale 7 est pivotante autour d'un axe principal A7, et est agencée pour commander directement ou indirectement la rotation du mobile d'affichage de lune 3.According to the invention, the drive means 5 comprise an input rocker 50 pivoting about an input axis A5. This input rocker 50 has a first end 51, which is arranged to cooperate with the internal toothing 2, and a second end 52, which is arranged to cooperate in thrust support with a bearing surface 72 which has a main rocker. 7. This main rocker 7 is pivotable about a main axis A7, and is arranged to directly or indirectly control the rotation of the moon display mobile 3.

Plus particulièrement, la bascule principale 7 et la bascule secondaire 8 sont agencées l'une par rapport à l'autre pour assurer un retard de mouvement de la bascule secondaire 8 par rapport à la bascule principale 7, quand la bascule principale 7 est entraînée par la bascule d'entrée 50.More particularly, the main rocker 7 and the secondary rocker 8 are arranged relative to each other to ensure a delay in movement of the secondary rocker 8 relative to the main rocker 7, when the main rocker 7 is driven by the input flip-flop 50.

Dans une réalisation particulière non limitative et illustrée par les figures, la bascule principale 7 comporte une goupille 71 circulant dans une rainure oblongue 81 que comporte la bascule secondaire 8, de façon à éviter une blocage de la bascule principale 7 et de la bascule secondaire puisque l'axe principal A7 et l'axe secondaire A8 sont distincts. Dans une application particulière, cette rainure oblongue 81 peut être ajustée en longueur pour assurer le retard de mouvement de la bascule secondaire 8 par rapport à la bascule principale 7 quand la bascule principale 7 est entraînée par la bascule d'entrée 50. Ce retard permet d'éviter une pointe de consommation d'énergie qui interviendrait en cas d'entraînement simultané de l'affichage de quantième et de l'affichage de phase de lune.In a particular nonlimiting embodiment and illustrated by the figures, the main lever 7 comprises a pin 71 circulating in an oblong groove 81 which comprises the secondary lever 8, so as to avoid blocking of the main lever 7 and of the secondary lever since the main axis A7 and the secondary axis A8 are distinct. In a particular application, this oblong groove 81 can be adjusted in length to ensure the movement delay of the secondary rocker 8 relative to the main rocker 7 when the rocker main 7 is driven by the input flip-flop 50. This delay makes it possible to avoid a peak in energy consumption which would occur in the event of simultaneous driving of the date display and the moon phase display.
