Definitions

  • the present invention relates to the field of watchmaking. More specifically, it relates to a device for correcting a display mechanism of the type comprising two display members of a time indication, one of which drives the other in rotation, at least indirectly. These members are preferably rotatably mounted behind a dial provided with a window.
  • Such mechanisms are, for example, mechanisms for displaying a large date date, an annual calendar or a perpetual calendar.
  • They generally comprise two display members, for example a ring provided with teeth on its inner side, and a disc concentric with the ring, mounted on a mobile provided with a toothing.
  • the display members have, on their upper face, time indications, such as the units and the tens of a date, or the calendars and the months of the year, or the calendars and the days of the week. .
  • They are driven by steps, at different rates of rotation. Generally, the first of them takes one step per day, while the second takes one step per week, per decade, or per month.
  • the first display member animated by the fastest rate of rotation, is driven directly by a training mobile.
  • the second member is driven either independently of the first, by the drive wheel and at least one intermediate wheel, or depending on the first, through it.
  • a first category relates to devices for directly correcting the first rotation member, animated by the fastest rate of rotation, the second member being corrected indirectly via the first.
  • This correction device only applies to display mechanisms for which the second member is driven by the first.
  • Such a device is generally formed of a correction wheel driven by the winding stem and engaged with the toothing of the first display member. The correction can be made in one direction or the other of rotation.
  • a second category relates to devices for directly and independently correcting the two display members.
  • This device can be adapted to a display mechanism as described above, regardless of the driving mode of the second display member, independently or depending on the first.
  • Such a device is conventionally formed of a wheel of correction driven by the winding stem, and a sliding pinion engaged with said correction wheel and movable in a curved oblong hole, so as to pass from a first stable position in which said pinion is engaged with the toothing of the first display member, at a second stable position in which the pinion is engaged with the toothing of the second display member.
  • the transition from one position to another is done by reversing the direction of rotation of the winding stem, each display member being able to be corrected only in a direction of rotation.
  • Such a device is described in the application JP 2000-314778 .
  • a suitable correction device will be chosen, knowing that as regards the mechanisms for which the drive of the second display member is made via the first, two possibilities exist for the device. correction.
  • the display mechanism and its correction device being generally mounted on a common bridge, called display module bridge, it must be adapted to the chosen display device.
  • display module bridge When the choice of the customer can be carried out on one or the other category of correction device, the manufacturer will have to provide two types of bridges, adapted, respectively, to the first and the second category of correction device.
  • the multiplication of the number of parts to manufacture, store and manage increases the cost of production and increases the risk of error handling and assembly.
  • the correction device of a display mechanism according to the invention overcomes these disadvantages.
  • the invention relates to a device for correcting a display mechanism for a timepiece of the type comprising a first display member and a second display member, the first member being arranged to drive at least indirectly.
