Definitions

  • the present invention relates to a timepiece comprising a movement and a calendar mechanism comprising at least one date display mechanism with a date indicator.
  • Timepieces comprising a calendar mechanism with a calendar are classic complications frequently integrated into mechanical watches.
  • the calendar display is generally of reduced size, therefore not very legible, or constituted by two numbers arranged on separate disks, which confers an unattractive appearance.
  • the calendar jump at midnight is not instantaneous and accurate but may take several hours to pass for example from 28 February to 1 March, which is not acceptable especially in the context of a display high accuracy by window.
  • the object of the present invention is to overcome these drawbacks and the invention is characterized for this purpose by the features in claim 1, namely that at least the date indicator is driven by a large mounted lever. pivoting on a fixed part and likely to occupy daily a rest position, a lever of the months being pivotally mounted on the large rocker and having a first portion intended to come into contact with a cam of the months performing one turn per year to lift daily during said rest position the number of days of the current month and a second part likely to come into contact daily during an active phase with a drive rake pivotally mounted on said fixed part and set in motion by a driving cam performing one turn a day, the rake and the lever of the months being arranged so that the rake performs a no-load run for a predetermined distance during an inactive phase before coming into contact with said second part during said active phase, this predetermined distance being variable and a function of the number of days of the current month so that the large flip-flop is driven by the lever months during said active phase in a rotational movement
  • the rake and the lever of the months are arranged so that said empty stroke is minimal for the months to 28 days and maximum for those 31 days, such that the large scale is raised against the effect of a spring of recall during said active phase approaching 24 hours for months to 28 days.
  • the date indicator is constituted by a rotating annular piece bearing the date markings 1 to 31, this annular piece having a toothing cooperating with a large latch ratchet pivotally mounted on the large scale so that this ratchet of big rocker daily skips the date indicator of a single step when the fall of the large rocker regardless of the amplitude of the rotational movement of the large rocker.
  • the large rocker is provided with a finger months with a pin biased elastically against a portion of the annular piece which has a notch in which the pin falls at the end of each month, so that the large rocker by the intermediary of his finger of months advance the annular piece during its fall to achieve, at the end of each month, the catching up of the days between the last day of the month concerned and the first day of the following month.
  • the calendar mechanism furthermore comprises a mechanism for displaying the months comprising an indicator of the months integral with the cam of the months and a star of the months, said finger of the months being provided with a hook arranged so as to cooperate with the star of months at the end of each month when his pin fell in the notch to perform, when the fall of the big rocker, the rotation of a step of the star of months.
  • the toothing of the annular piece is advantageously made in non-through form on a rear face of the annular piece so as to allow large date inscriptions on a front face of this annular piece.
  • the date display can thus be made particularly visible and large.
  • the calendar mechanism comprises a day display mechanism comprising an integral day indicator of a star of days, the large scale being provided with a pivotally arranged day finger to make to skip day by day when he falls the star of the days of a single step whatever is said amplitude of the rotational movement of the big rocker.
  • the calendar mechanism comprises a date-driven mobile carrying out a revolution per day in a first direction of rotation around a shaft on which the drive cam is mounted freely rotating, a date finger being pivotally mounted on this drive cam and biased, for driving the drive cam in said first direction of rotation, elastically in a notch of the date drive mobile so that the date finger can leave the notch, when the mobile date coach is rotated in an opposite direction of rotation during a time setting.
  • the calendar mechanism includes a date display by window larger than the wickets displays months and days between 1 and 2 hours and between 10 and 11 hours, which are an identical or similar size.
  • the resulting display is balanced, harmonious and readable.
  • the timepiece 10 shown in the figures is of the mechanical movement type and comprises a calendar mechanism 11 in the form of an instantaneous perpetual calendar mechanism forming an additional mechanism that can be mounted on a suitable base movement 17.
  • the calendar mechanism 11 includes a date display mechanism 12, a month display mechanism 13 and a day display mechanism 14.
  • the entire timing mechanism 11 is driven from a centrally located calendar driver 16 and assembled with the hour wheel (not shown) of the base movement 17.
  • This return 16 calendar trainer performs two laps per day and engrains with a date driving mobile 18 rotating in one turn per day to drive a date cam 20 mounted to rotate on the same axis 21 as the date driving mobile 18 ( Figures 1 and 5).
  • the latter drives the date cam 20 via a date finger 22 which is pivotally mounted on the cam 20 by means of a pin 23.
  • the pin 21 is pivotally mounted between two stones driven in a calendar board 28 and a mobile drive bridge 34.
  • the date cam 20 is free around this axis 21.
  • the driving mobile 18 has a hub 24 provided with a notch 25 in which the date finger 22 is biased by a spring 26 mounted under the cam 20 by means of a screw 29.
  • the driving mobile 18 rotates in a counterclockwise direction and the date cam 20 is integral with the driving mobile 18 because the notch 25 is in contact with the date finger 22.
  • the driving mobile 18 rotates in a clockwise direction and the date finger 22 can exit the notch 25 when the date cam 20 comes into contact with a rake 27.
  • This clutch avoids the breakage when we pass midnight by setting a time back.
  • the calendar mechanism comprises a cam of the months 30 running one turn per year in a counterclockwise direction.
  • This cam of the months is of the cam type of 12 formed of a succession of troughs 31 and bumps 32 for the eleven months of 30 and 31 days and a cam of four years 35 for the month of February.
  • Three sides of this four year old cam 35 are close of its axis of rotation 36 for February 28.

  • the four-year-old cam 35 is secured to a four-year-old wheel 38 and rotates around the axis of rotation 36 mounted on the 40-year-old star.
  • This four-year-old wheel 38 forms a satellite wheel which revolves around the fixed gear 39 meshing with the latter.
  • the four-year cam 35 performs 2 turns and 1 ⁇ 4 on itself.
  • a lever 45 months comes by a point 46 bearing against the cam 30 months or cam four years 35 in the month of February.
  • the toothing 47 of the star of the months 40 cooperates, on the one hand, with a first jumper of months 48 whose two functional flanks 48a, 48b reposition this star of the months with a favorable and constant sliding angle and, on the other hand on the other hand, with a second jumper of unidirectional months 49 whose functional flank 49a is arranged so that the direction of the force applied to the teeth of the toothing 47 passes through its center of rotation.
  • the flanks 47a of the teeth of the toothing 47 are aimed at the center of the fixed axis 42.
  • the two jumpers 48, 49 are subjected to the action of two superposed return springs 50.
  • the flank 48a of the first jumper of the months 48 is in contact with one of the teeth of the toothing 47 and the flank 47a of this tooth bears against the functional flank 49a of the second jumper of the teeth.
  • month 49 the 40-month star has a well defined rest position. It should be noted that in this position, the functional flank 48b of the first jumper months 48 is not in contact with the neighboring tooth, but separated from the latter by a gap.

  • the lever 45 months can therefore, in a rest position just after midnight, when not in contact with the rake 27, be in four different positions, depending on the number of days of the current month. As a result, its second part 66 will come into contact with the rake 27 more or less quickly. The rake 27 driven by the date cam 20 will have a longer or shorter idle stroke during the inactive phase until it meets the lever of the months 45.
  • this empty run of the rake is very short, minimum for the months of February to 28 days, for which the rake 27 will therefore push the lever of the months 45 and the large latch 60 during a very active phase. long approaching 24 hours on a very long angular displacement in a clockwise direction around the axis 61.

  • lever of the months 45 and the big latch 60 occupy daily just after midnight a rest position during which the lever 45 months the number of days of the month In progress.
  • the rake 27 performs a no-load run for a predetermined distance before coming into contact with the month lever 45, this active distance being variable and a function of the number of days of the current month.
  • the large flip-flop 60 is driven via the lever of the months 45 in a clockwise rotational movement whose amplitude is a function of the said number of days of the current month. Then the large latch 60 performs a fall in the opposite direction at the end of this active phase by driving all the display mechanisms.
