Abstract

La présente invention concerne un dispositif de commande pour mouvement horloger, comportant une couronne de commande (1), une tige de commande (2), reliant cinématiquement la couronne de commande (1) au mouvement, un tube de couronne (3) monté sur une carrure (4) et au travers duquel s'étend la tige de commande (2), un moyen de montage pour maintenir et monter rotative la couronne de commande (1) sur le tube de couronne (3), et des moyens d'ajustement pour ajuster automatiquement la longueur du sous-ensemble constitué par la couronne de commande (1) et la tige de commande (2), caractérisé en ce que les moyens d'ajustement comprennent un logement (6) ménagé dans la couronne de commande (1), dans lequel est engagée une portion axiale du tube de couronne (3), une portion d'extrémité de la tige de commande (2) montée coulissante dans le tube de couronne (3) et un ressort (11) disposé dans le logement (6) entre la portion d'extrémité et un appui situé dans ledit logement (6), de manière à contraindre axialement la tige de commande (2) vers le mouvement.
