Definitions

  • Document is known FR 2.165.705 a timepiece equipped with a simple calendar equipped with a mechanism for the monthly correction of the indication of this simple date.
  • the present invention relates to a rapid correction mechanism of the calendar for a watch movement provided with an annual or perpetual calendar.
  • the aim of the present invention is to create a mechanism for rapid correction of the date of a calendar watch movement with an annual or, above all, perpetual calendar, making it possible to considerably reduce the number of successive manual corrections for updating the date.
  • the mechanism for rapid correction of the calendar for a watch movement provided with an annual or perpetual calendar object of the present invention tends to overcome the aforementioned drawbacks and to allow the rapid correction, in a number of limited successive operations, of the date display.
  • This mechanism is distinguished by the features defined in claim 1.
  • the figure 1 is a plan view of the mechanism in the rest position when no correction is made.
  • the figure 2 is a plan view of the mechanism in the active position during a fast manual correction operation.
  • the perpetual perpetual calendar mechanism illustrated in figures 1 and 2 in principle, it contains a star of months 1 and a star of date 2.
  • the star of months 1 has twelve teeth and is driven at a rate of one step per month by rocker 3.
  • This month star has steps 4,5 whose radius corresponds to the duration of the months of 30 and 31 days.
  • a February 6 scale has a cam that changes its radius once every four years for leap years. These steps 4, 5 and 6 cooperate with a spout 7 of a large rocker 8 pivoted at 9.
  • the date star 2 carries a toothing of thirty-one teeth 10 cooperating with a first pawl 11 of the large latch 8 causing its training a step per day.
  • star 2 carries a first spiral cam 12 cooperating with a second pawl 13 of the large flip-flop 8 causing the advance of this star 2 one, two or three additional steps depending on the position of the large latch 8 and the star of the month 1 at the end of a month of 30, 29 or 28 days.
  • the date star 2 still carries a second spiral cam 14 cooperating with an end 15 of the rocker 3 and causes, once a month, the advance of a step of the star of the month 1 via a ratchet 16 of this rocker 3 pivoted at 17.
  • the spout 18, at the free end of the large rocker 8, cooperates with a finger 19 driven by a pin 21 of a twenty-four hour wheel 20.
  • the large rocker is held in position applied against a step 4,5,6 of the cam of the months 22 by means of a return spring 23; the star of the months 1 is maintained between successive drives in an angular position defined by a jumper 24 and the date star 2 is maintained between its daily stepping by a jumper 25 in a specific angular position.
  • the illustrated mechanism further comprises a traditional correction push-button 26 subjected to the action of a return spring 27.
  • the user by pressing this push-button, causes the actuation of the big rocker 8 and the driving of a , two or three steps of the date star 2 according to the angular position of the star of months 1.
  • This pusher therefore allows to advance step by step the date as in the traditional mechanisms.
  • This rapid correction mechanism comprises an actuating member 30 integral with a slide 31 sliding in a slide of the movement not shown.
  • This slide and this slider 31 have the shape of a circular arc concentric with the movement and located on the periphery thereof.
  • the actuating member 30 is accessible from outside the timepiece.
  • the front face of the slider 31 has an inclined plane 32 cooperating with the pin 33 secured to one end of a lever 34 pivoted in its middle at 35.
  • the other end of the lever 34 carries a pin 36 cooperating with the jumper 25 of the date star 2.
  • the slider 31 carries a toothed sector 37 whose teeth are in mesh with that of a sliding pinion 38 subjected to the action of a spring 39. In the rest position of the mechanism, this sliding pinion 38 is not engaged with the toothing of a first wheel 40.
  • This wheel 40 is in constant engagement with the teeth of a return 41 meshing itself with a pinion 42 carried by the date star 2.
  • the lever with two arms 43,44 is pivoted at 45.
  • One of its arms 43 cooperates with a notch 46 formed in the slide 31 constituting with it a cam while the other arm 44 cooperates with the large latch 8 .
  • a second step when the user continues to move the operating member 30 in the direction of the arrow F, the sliding pinion 38 is moved so as to mesh with the wheel 40. From this moment, the large latch 8 being isolated and the date star released, any subsequent movement of the actuator 30 in the direction of the arrow F causes the rotation of the date star 2 by the kinematic link 37,38,40,41 and 42. If doing so, we pass the position of the corresponding date star 2 at the end of a month, the star of the months 1 is driven normally by the flip-flop 3.
  • a displacement of the actuating member may correspond to the training of the calendar for several months without the perpetual calendar mechanism being disrupted.
  • the user releases the operating member which returns to the rest position under the action of a spring not shown.
  • the sliding pinion 38 is decoupled from the wheel 40 and, at the end of the stroke, the perpetual rocker 8 is put back in place by bearing on the star of the months 1 and the spring 25 fixes again the angular position of the date star 2.
  • the user can operate one or two times the pusher 26 if necessary.
  • this actuator actuates in the second part of its stroke a disengageable kinematic connection rotating the date star.
  • this disengageable kinematic connection is formed of a rack 37 carried by the slide 31 meshing with a sliding pinion 38 as well as the gear wheels 40, 41 and the pinion 42 carried by the date star 2.
