Problems solved by technology

The disadvantage of this mechanism is that it requires two cams or at least two cam levels to control the activation and disengagement of the jumper
Furthermore, the mechanism is configured to lock the jumper, i.e. to fix the jumper completely in the designated position, which would be unavoidable in the case of such a calendar mechanism provided with correction means including a quick corrector for the date indication and / or the day of the week indication produce uncorrected range

Abstract

The invention provides a system (90) for driving and in position a mobile unit (50) displaying time or time derived information, comprising: means (80) for driving the mobile unit (50), comprising a drive cam (13) and a drive lever (30) arranged to drive a drive member (23), means (40) for holding the mobile unit (50) in position, and means (40) for moving the mobile unit (50) in position, means (70) for activating and deactivating the position holding means (40), comprising a deactivating cam (22) and means (12, 21) for mechanically coupling or synchronizing the drive cam (13) and the deactivating cam (22).

Description

technical field [0001] The invention relates to a system for actuating and positioning a mobile unit displaying time or time derived information. The invention also relates to a timepiece-calendar system comprising such a driving and position-keeping system. The invention also relates to a movement comprising such a drive and position-keeping system or such a horological-calendar system. The invention also relates to a timepiece comprising such a movement, such a drive and position-keeping system or such a horological-calendar system. The invention also relates to a method for operating such a timepiece, such a movement, such a drive and position-keeping system or such a timepiece-calendar system. Background technique [0002] Document CH525507 discloses a date drive mechanism that disarms the jumper of the date disc at the moment of instantaneous triggering of the date changeover. The energy required for date conversion is accumulated in a return spring arranged between ...
