Abstract (fr)

Mécanisme de quantième annuel pour mouvement d'horlogerie comportant: une liaison cinématique reliant un mobile (13) du mouvement d'horlogerie à un rouage des jours (8) et provoquant l'avance d'un pas par jour de ce rouage des jours (8), un rouage des mois (9) comportant une denture formée de dents tronquées et de cinq dents complètes (19) correspondant aux mois de trente jours, ces dents complètes étant entraînées par la liaison cinématique, de sorte qu'à la fin du trentième jour des mois de trente jours cette liaison cinématique provoque successivement l'avance d'un pas du rouage des jours (8) et l'avance d'un pas du rouage des mois (9), un rouage intermédiaire (10) en prise avec toutes les dents du rouage des mois (9) et engrenant avec un doigt d'entraînement (18) solidaire du rouage des jours (8) de sorte que, d'une part, une fois par mois le rouage des mois (9) soit avancé d'un pas par l'intermédiaire du doigt (18) et du rouage intermédiaire (10) et que, d'autre part, chaque fois que la liaison cinématique engrène avec une dent complète (19) du rouage des mois (9) le rouages des jours (8) soit entraîné par le rouage intermédiaire (10) et le doigt (18) d'un second pas. <IMAGE>
