Patent ID: 8398299

Claim:
A display mechanism for a timepiece, adapted to be driven from a base wheel ( 1 , 5 ) of a clock movement to actuate the movements of a display device for displaying at least one indication relative to the time or the operation of the timepiece, the mechanism comprising a cam ( 7 ) having a periphery of predefined form and which is adapted to be driven by the base wheel, a lever ( 10 ) adapted to be pivotally mounted, with reference to a support member of the clock movement, between an abutment position, associated with an indication position of the display device, and a waiting position, associated with a predefined alternative position of the display device, said lever bearing a cam follower ( 14 ) adapted to cooperate with the periphery of said cam to define said abutment position, the lever furthermore bearing a rack ( 12 ) arranged in meshing engagement with a pinion ( 13 ) adapted to drive the display device, a movable actuating device ( 24 ) having at least a waiting position and an indicating position, both being stable positions, said actuating device being arranged to pass alternately from one position to the other in response to successive actions of a user, elastic means ( 15 ) exerting a force on said lever to bias it into said abutment position, said actuating device also being arranged to oppose the action of said elastic means ( 15 ) in its waiting position and enable said lever ( 10 ) to assume its waiting position, characterized in that said cam is adapted to be driven continuously, independently of the positions of said movable actuating device and of said lever.
