Definitions

  • the present invention relates to the field of watchmaking and more particularly relates to a mechanism for selecting and operating functions of a watch movement.
  • a timepiece is generally equipped with several functions. For example, a function common to all timepieces is the setting time to adjust the display of the current time. Another function common to all mechanical watches is the reassembly of the energy source. If the timepiece makes it possible to display other time indications than the current time, it must also include correction functions for the different displays.
  • This correction mechanism comprises a winding stem, a corrective mobile mounted walker between a first and a second correction positions in which the mobile is in kinematic connection respectively with the first and second time indicating members.
  • the mechanism comprises means for driving the corrective mobile with the winding stem, and a correction position selection mechanism comprising a selector arm cooperating with the corrective mobile to drive it from the first correction position to the second correction position, an angular positioning member of the selector arm and a control member of said angular positioning member.
  • this mechanism because of its construction, is limited to the correction of two functions only.
  • CH702548 describes a selection mechanism that can be in the neutral position or move between two pressure correction positions on the winding crown, the correction being made only by rotation of the winding crown, without having to pull the rod winding.
  • the mechanism comprises a rocker having two arms on each of which is mounted a correction mobile.
  • the flip-flop pivots to select and actuate one or the other of the two functions to be corrected by means of one of the correction mobiles. put in contact with an organ of the function to be corrected.
  • this mechanism because of its construction, is limited to the correction of only two functions, the rocker being able to rotate only between two positions.

  • the arm moves angularly relative to the control lever in response to a rotation of the crown to be placed opposite one or the other of the correction levers.
  • the control lever pivots to actuate the selected correction lever in response to an action on a pusher. Correction can only be done by incrementing the different counting devices, which makes bidirectional operation impossible. Only unidirectional correction of counting devices is possible.
  • the object of the present invention is to overcome these disadvantages, by providing a mechanism for selecting and operating n functions of a watch movement for selecting and operating more than two different functions of a watch movement.
  • a mechanism for selecting and operating functions of a watch movement comprises a winding stem terminated at one of its ends by a crown.

  • the mechanism further comprises a cam wheel which, when the selection mechanism is in its second position, is kinematically connected to the winding stem, said cam wheel having a guide element on which are arranged n rest positions corresponding to each to a function.
  • the mechanism includes a clutch device having gear wheels, the clutch device temporarily engaging the workings of the watch movement to actuate one of n functions.
  • the clutch device comprises an elongated plate having holes adapted to receive gears, pivoting about one of the axes of said holes to actuate one of n functions.
  • the guide element is a groove arranged in the cam wheel, the groove being for example in the form of a curved line, in particular a curved line open at two ends.
  • a tenon engages in the groove arranged in the cam wheel, around which a pinion can rotate freely, the pin being integral with the elongated plate.
  • the mechanism comprises among the n functions, a time setting function, a date correction function and a display function of at least a second time zone.
  • n the number of functions
  • a time setting function a time setting function
  • a date correction function a display function of at least a second time zone.
