Definitions

  • the present invention relates to a timepiece comprising an annual display mechanism or perpetual calendar.
  • the known mechanisms for displaying annual or perpetual calendars generally include, in addition to the indication of the dates, that of the month being displayed and the days of the week. To these indications relating to the division of time, based on the duration of rotation of the Earth around the Sun, are sometimes added indications relative to the position of other stars relative to the Earth, in particular that of the Moon.
  • any annual or perpetual mechanism of calendars necessarily includes a cam of months to define the number of days of the month being displayed, none of these mechanisms proposes a display device to indicate how many days ago there are the month being displayed. This is an extremely useful indication in everyday life.
  • the object of the present invention is to allow the use of this display potential not exploited so far.
  • this invention relates to a timepiece comprising an annual or perpetual date display mechanism according to claim 1.
  • the essential advantage of this invention is to offer the display of an additional indication which was not yet available until now for the mechanisms of annual or perpetual display of the dates.
  • the means for actuating the display device of this timepiece comprise a drive flip-flop of an indicator of this device display, a cam of the months of the date mechanism, a spring for pressing the drive rocker against the cam months and a kinematic connection between the indicator element and the drive rocker.
  • This device has very few parts, so it is simple and reliable.
  • Figure 1 is a plan view of the perpetual calendar mechanism of this timepiece
  • Figures 2 to 5 are partial top views of the mechanism of Figure 1 showing the means for actuating a display device of the number of days of the month being displayed, in its four display positions possible.
  • the timing mechanism of the timepiece object of the present invention comprises an actuating wheel 1, driven at a rate of 1 turn per 24 hours in the direction of the arrow F, by the barrel wheel 1b of the clockwork of the timepiece.
  • This actuating wheel 1 carries a pin 1a which serves to drive a finger 2 pivotally mounted on the same axis as the actuating wheel 1.
  • a large rocker 3 is pivotally mounted about an axis 4 and is pressed against a cam of months 5 by a spring 6 which tends to rotate this large rocker 3 about this axis 4 in the direction of clockwise.
  • This large rocker 3 serves to control the main functions of the calendar. For this purpose, it comprises an actuating spout 3a of the days of the week, a first driving ratchet 3b of a date wheel 7 positioned by a jumper 15 which has 31 teeth, and a large pawl 3c which cooperates with a correction cam 7a spiral, integral with the date wheel 7.
  • This date wheel 7 still carries a second cam 7b in spiral against which presses a rocker 8, under the pressure of a spring 9.
  • This rocker 8 carries a pawl 8a for driving an annual wheel 10, positioned by a jumper 16 secured to the cam of the months 5.
  • This annual wheel 10 has twelve teeth and is driven one step every revolution of the date wheel 7, so that it itself performs a revolution per year.
  • a second rocker 11 is pressed by a spring 12 against the cam of the months 5.
  • This second rocker 11 has a toothed sector 11a engaged with a pinion 13a coaxial with an indicator element 13 of the display device of the number of days of the month. display course, pivotally mounted on an axis 18.
  • the cam of the months like practically all the cams of the month of the perpetual calendar mechanisms, comprises nine angular portions formed of an alternation of circle segments 5a centered on the axis of the annual wheel 10 and of straight portions 5b tangent to one another. circle of smaller diameter, so that these circle segments 5a and these straight portions 5b alternately define two respective positions of the second flip-flop 11 and therefore also two respective angular positions of the indicator element 13, depending on whether the current month 30 or 31 days.
  • the cam 5 is replaced by a cam 14 which is integral with a planet pinion located under the annual wheel 10 and which meshes with a fixed gear coaxial with the annual wheel 10.
  • This cam 14 comprises two segments, one of large diameter for display February 29 day, which extends over 90 ° and the other smaller diameter for February displays of 28 days, which extends over 270 °.
  • This cam 14 is keyed on the axis of its pinion satellite so that the small diameter portion comes into contact with the ends 3e, 11b of the latches 3, respectively 11 in all the years when the month of February has 28 days, while the large diameter portion of this cam 14 comes into contact with the same ends of the flip-flops 3 and 11 only in leap years, when the month of February to 29 days.
  • Figures 2 to 5 illustrate the four positions that can occupy the indicator element 13 of the display device of the number of days of the month being displayed. Each of these angular positions corresponds to a number corresponding to the number of days of the month being displayed.
  • the finger 2 drives a lug 3f of the large rocker 3.
  • the position of this lug 3f varies depending on the initial position of this large rocker 3 bearing against the annual cam 5 or against the cam of February 14.
  • the amplitude of the big rocker 3 is even larger than the number of days of the month is low.
  • the large pawl 3c comes into the recess of the correction cam 7a, so that when the lever 3 is driven by the finger 2 of the actuating wheel 1, the date indicator goes directly from 30 to the 1 of the following month.
  • the large pawl 3 returns the date indicator to the number 1 for the beginning of the following month by driving the date wheel one, two, three or four steps at a time. next month is 31, 30, 29 or 28 days.
  • the latch 8 falls into the recess of the cam 7b, driving one step the annual wheel 10.
  • the latch 3 takes a another position if the number of days of the following month changes and it is the same for the second latch 11 of the device indicating the number of days of the month, causing the positioning of the indicator element 13 vis-à-vis the digit corresponding to the number of days in the current month.
