Abstract
La pièce d'horlogerie comporte au moins un mécanisme chronographe avec au moins un rouage entraîné par un barillet, au moins un indicateur de la durée mesurée, au moins un balancier (46) et une roue à colonnes (71) destinée à contrôler le mouvement d'au moins un marteau (81) pour la remise à zéro dudit indicateur. Le mécanisme chronographe est muni d'un fouet (70) monté de façon mobile sur la pièce d'horlogerie et présentant une languette élastique (74) susceptible de coopérer avec le balancier (46) pour lancer ce balancier (46) lors du départ du mécanisme chronographe et pour arrêter le balancier (46) lors de l'arrêt du mécanisme chronographe. La roue à colonnes (71) comprend au moins deux étages superposés, un premier des étages étant agencé pour contrôler le mouvement du ou des marteaux (81) et un second étage coopérant avec un bec du fouet (70) pour piloter les déplacements de celui-ci lors du lancement et de l'arrêt du balancier (46). On obtient ainsi un démarrage immédiat et un arrêt très précis du chronographe et un fonctionnement très fiable du mécanisme chronographe.The timepiece comprises at least one chronograph mechanism with at least one wheel driven by a cylinder, at least one indicator of the measured duration, at least one balance (46) and a column wheel (71) for controlling the movement at least one hammer (81) for resetting said indicator. The chronograph mechanism is provided with a whip (70) movably mounted on the timepiece and having an elastic tongue (74) capable of cooperating with the rocker (46) to launch the rocker (46) when leaving the chronograph mechanism and to stop the balance (46) when stopping the chronograph mechanism. The column wheel (71) comprises at least two superposed stages, a first of the stages being arranged to control the movement of the hammer (s) (81) and a second stage cooperating with a whip spout (70) to control the displacements of the when launching and stopping the balance (46). This gives an immediate start and a very precise chronograph stop and very reliable operation of the chronograph mechanism.
