CLOCKWORK MOVEMENT

摘要

The invention relates to a clockwork movement comprising a control member actuatable by a control lever (20) in response to a user's action and embodied in the form of a column wheel (40). Said control member is rotatably mounted on the clockwork movement frame around an axis X, which is perpendicular thereto, for controlling first and second mechanisms exhibiting at least one movement function such as chronograph or alarm function. For this purpose, the control member comprises rotationally fixable first, second and third parts (35, 4, 45, 53) which are mounted on a shaft (41) at first, second and third levels, respectively, in a direction of the axis X for interacting with the control lever and for controlling said mechanisms. In addition, the shaft (41) which is pivotally mounted with respect to the frame is arranged in at least two bearings (49, 51), which are positioned remotely to each other for ensuring the shaft good stability, whereas the second and third parts are located on the both parts of the frame. In the preferred inventive embodiment, the end of the shaft (41) opposite to the control member is provided with a square (42) onto which a sleeve (43) bearing the third part is engaged.
