Definitions

  • the present invention relates to a system for adjusting the position of a first toothed mobile relative to a support on which the first toothed mobile is pivotally mounted.
  • the present invention relates to a system for adjusting the angular position of a pinion carried by a wheel with which it forms a mobile.
  • the present invention also relates to a timepiece comprising such an adjustment system.
  • a conventional date display mechanism for a timepiece such as a wristwatch essentially comprises a date ring on the periphery of which are transferred the date indications from “1” to “31”. This date ring advances one step per day. At the end of months with less than 31 days, the owner of the watch must advance the date ring by the date indication "28" or by the date indication "29” in the event of a leap year until 'to the date indication "1" when it is in the month of February, and from the date indication "30" until the date indication "1" for the other months of the year having less of 31 days.
  • Date display mechanisms that require owner intervention at the end of every month less than 31 days are called simple date display mechanisms.
  • the display mechanisms of that require owner intervention only once a year, when February changes to March, are called semi-perpetual date display mechanisms.
  • the date display mechanisms which spontaneously switch from the date indication of the last day of a month of less than 31 days to the date indication of the first day of the following month, including leap years are called perpetual date display mechanisms.
  • the date display mechanisms which comprise a single ring around the periphery of which are distributed the date indications from “1” to “31” have the advantage of comprising a limited number of parts. They are therefore more economical and easier to integrate into a clockwork movement of a mechanical or electromechanical watch. On the other hand, there is only one angular sector of a little less than 12° to reproduce each of the 31 date indications on the date ring. The size of the date indications is therefore necessarily limited by the dimensions of the date ring, which can make these date indications difficult to read.
  • date display mechanisms whose display member is a ring on which the thirty-one date indications are shown, there are also date display mechanisms known as “big date” designed to equip mechanical or electromechanical timepieces. These large date calendar display mechanisms are so called because they allow the date indication to be displayed on a larger scale, which makes it easier to read the date and brings an undeniable plus to the aesthetics of the piece. watchmaking equipped with such a mechanism.
  • Large date date display mechanisms conventionally comprise a first date indicator on which are transferred the indications of the date units from “0” to “9”. These 10 digits are reproduced on the first date indicator according to sequences which depend on the mode of operation of the large date display mechanism considered. These date display mechanisms are completed by a second date indicator on which are reproduced the indications of the tens of the date from “0” to “3”.
  • a first date indicator on which are transferred the indications of the date units from “0” to “9”.
  • These 10 digits are reproduced on the first date indicator according to sequences which depend on the mode of operation of the large date display mechanism considered.
  • These date display mechanisms are completed by a second date indicator on which are reproduced the indications of the tens of the date from “0” to “3”.
  • the first date indicator bears only the indications of the date units and the second date indicator only the indications of the tens of the date, there is more room to reproduce these indications which can therefore be of larger size. Reading a large date date indicator device is therefore easier and the appearance of a timepiece equipped with such a date indicator device is greatly improved.
  • the date display mechanisms of the “big date” type nevertheless pose a problem when changing from “31” of a given month to “01” of the following month.
  • the indication of the date unit "1" which is used to compose the date indication "31” is the same as the indication of the date unit "1” with which composed the date indication “01”. Consequently, during the passage from the date indication "31” to the date indication "01", the indication of the date unit "1" must remain unchanged, while the indication of the tens of the date changes from the value "3" to the value "0".
  • the first date indicator on which the indications of the date units are transferred must remain stationary. To achieve this objective, it is necessary to prevent the clock movement which, in normal times, ensures the daily advance of the large date display mechanism, from driving the first indicator of date when changing from the last day of a 31-day month to the 1st day of the following month.
  • the solution usually proposed to solve this problem consists in depriving one of the wheels which is located in the kinematic chain between the output of the clockwork movement and the date indicator which bears the indications of the date units by at least a tooth so that, when changing from "31" to "01", this wheel, although driven by the clockwork movement, is unable in turn to drive the pinion with which it is in mesh and which , too, takes part in driving the date units indicator.
  • the pinion remains immobile during this period, the kinematic connection between the clock movement and the first date indicator which bears the date unit indications is interrupted, and the date unit indication "1" remains unchanged.

It is therefore essential for the indicator of the date units to remain stationary during this lapse of time so that the date indication which appears through an aperture provided in a dial of the timepiece is accurate. As a result, it is necessary to decouple the drive pinion from the units so that the clock movement which operates permanently cannot drive the indicator of the date units.
