Definitions

  • the present invention relates to a part horological, in particular a wristwatch, comprising a date display device of the so-called type "retrograde" (see patent CH-A3-666,591, fig.1, p.4, col. 9., ll. 12-15).
  • the object of the invention is to provide a mechanism for control of this retrograde display device of the date which is reliable, simple and efficient, which does not take no place at the center of the movement and that can easily adapt to any movement involving date crown.
  • Figure 1 is a perspective view of a wristwatch.
  • Figure 2 is a perspective view of the retrograde date display control.
  • the wristwatch includes a dial 1 provided with a graduation from 1 to 31 for the date 2 cooperating with a hand 3.
  • This hand 3 is driven by a date mechanism of so that every day it is moved angularly of a value corresponding to a step of the graduation 2 then when it arrives at 31 it moves one blow back, either counterclockwise a watch to display the first day of the month next.
  • the mechanism according to the invention for driving hand 3 of the date display is very simple and can be grafted onto any watch movement including a date crown.
  • Hand 3 of the retrograde date display is carried by a barrel 4 secured to a pivoted pinion 5 in plate 6.
  • This pinion 5 is engaged with the teeth of a first rake 7, pivoted on plate 6 and subjected to action a return spring 8 tending to move the pinion 5 counterclockwise.
  • This same pinion 5 is also engaged with a second rake 9 also pivoted on plate 6 on the other side of the pinion axis 5.
  • the free end of this second rake 9 has a feeler or a roller 10 which abuts against a date crown 11.
  • This probe 10 is permanently held against the peripheral edge outside of the date crown 11 under the action springs 8 and pinion 5.
  • pinion 5, and therefore needle 3 are always positively held in a determined angular position, all sets of teeth of rakes and pinion are eliminated.
  • the date crown 11 is housed in the part lower device of the plate and pivoted or guided with play by a thicker central part of this plate 6.
  • the date crown 11 is kept high by bridges (not shown).
  • the training of date crown 11 is made by its internal toothing 12 conventionally using a finger or a tooth of a cog making one revolution per day.
  • the position angular of the crown 11 is maintained, between two successive trainings, by a jumper.
  • the peripheral edge 13 of the date crown 11 constitutes a snail cam so that for each angular pitch of the crown 11 the probe 10 causes a angular pitch of the barrel 4 and therefore of the needle 3 corresponding to the passage from one day to the next on the graduation 2. After the 31st of the month, the crown 11 has rotated 360 ° and the probe 10 falls from the value of the lift L of the snail cam which causes the return of needle 3 opposite the number 1 of the graduation 2.
  • the modification of the duration of the months is obtained automatically by the winding stem acting on the date crown 11 as in any movement comprising a rapidly correcting date crown.
  • This mechanism is very simple, it has only one pinion 5 and two rakes 7.9. It can be located in the periphery of the movement where we have enough square.
  • the date crown 11 is the element controlling the movement of needle 3, this crown is conventional except for the shape of its periphery which constitutes a snail cam. All advantages of this mechanism arise from the fact that taking forcibly actuating the date display mechanism retrograde is constituted by the date crown and especially its periphery.
  • the snail cam worn by the date crown could be different, for example formed from a machined shaped groove in the upper side of the crown.
