Definitions

  • the invention relates to the field of mechanical watchmaking. It relates, more particularly, to a watch movement comprising a control stem, a movement winding mechanism, a date display mechanism and a time display mechanism.
  • the invention relates to a mechanism for correcting the time and/or date.
  • Many mechanical watches traditionally include a control stem, located at 3 o'clock, which can occupy two positions, namely a manual winding position and a time-setting position. These watches may also include a date correction mechanism operated via this same control stem.
  • a clockwork movement comprising a first lever carrying a first drive wheel capable of being kinematically linked to the control stem, a second lever carrying a second setting wheel the time arranged to cooperate with the time display mechanism and capable of being kinematically linked to the first drive wheel, and a third lever carrying a date correction mechanism capable of being kinematically linked to the first drive wheel as well as to the date display mechanism, the third lever being pivotally mounted on the second lever and arranged to move between a meshing position in which the date correction mechanism cooperates with the date display mechanism and a retracted position in which the date correction mechanism is disconnected from the date display mechanism, and the control stem and the first and second levers are arranged to occupy three positions.
  • the document FR2169861 A1 describes a delay device for a stem setting mechanism of a winder, intended for use with a watch in which the stem of the winder can be selectively placed in several positions, the first of which allows correction of the displayed day and date and the second of which allows setting of the minutes.
  • the invention aims in particular to overcome the various drawbacks of known mechanisms.
  • an objective of the invention is to provide a watch movement allowing rapid correction of the time or date by the control stem.
  • the watch movement comprises a third lever arranged to cooperate with the second lever, the third lever being arranged to lock the second lever in the setting position. on time when the control stem is in the time-setting position and prevent the date from being corrected when correcting the time.
  • the invention also relates to a timepiece comprising a movement in accordance with the invention.
  • FIG. 3 it represents a part of a watch movement including in particular a control stem 1, a winding mechanism, a date correction mechanism and a time correction mechanism.
  • control stem 1 or winding stem is operable from outside the watch case and is mobile in rotation about its axis of revolution C on the one hand and in translation along its axis of revolution C on the other hand to occupy its different positions.
  • a winding pinion 2, a sliding pinion 4 are also provided, the positioning of the sliding pinion 4 being ensured by a pull 6 and a lever 8.
  • the winding pinion 2 meshes with the winding mechanism (not shown) to manually wind the movement when the control stem is in its winding position (generally its unpulled position) and the sliding pinion 4 cooperates with the winding pinion 2, as shown in the figure 1 .
  • the date display mechanism conventionally comprises a date disc or ring 3 having internal teeth 5 actuated by a date correction mechanism.
  • the time correction mechanism may include a set of gears meshing with a minute wheel which cooperates with a cannon pinion.
  • a first lever 10 is provided pivotally mounted on a plate and carrying a first drive wheel 11 mounted freely to rotate about an axis.
  • the drive wheel 11 is capable of being meshed by the sliding pinion 4 of the control stem 1 when the control stem is in the date correction or time setting position (pulled out positions).
  • a second rocker 20 is also provided, pivotally mounted on the first rocker 10.
  • the second rocker 20 comprises a first portion 20a provided with a first hole for the passage of a first shaft A, constituting the pivot axis of the second lever 20 on the first lever 10.
  • the second lever 20 also comprises a second portion 20b having a second hole for the passage of a second shaft B, constituting the pivot axis of the date correction means.
  • the second lever 20 carries a date correction mechanism capable of being kinematically linked to the drive wheel 11 as well as to the date ring 3.
  • the date correction mechanism comprises a correcting member 15 capable of being kinematically linked to the drive wheel 11 via a connecting pinion 16, the correcting member 15 comprising correction fingers 17 capable of cooperating with the toothing 5 of the date ring 3.
  • the correcting member 15 is frictionally mounted via a friction washer 18 on the second lever 20 via the shaft B secured to the correcting member 15.
  • the correcting member 15 and the connecting pinion 16 are secured, the assembly being mounted to move in rotation on the second lever 20.
  • correction fingers 17 cooperate directly with the date disc 3 but it is obvious that gears or other intermediate mechanisms can be provided between the correction member 15 and the date display mechanism.
  • the second lever 20 is pivotally mounted on the first lever 10 and is arranged to move between a meshing position in which the date correction mechanism cooperates with the date ring 3 and a retracted position in which the date correction mechanism is disconnected from the date ring 3.
  • the second rocker 20 also comprises a stop element, the stop element being in the form of an opening 20c so that the second rocker circulates between the two stops defined by the ends of the opening 20c, the ends of the opening 20c allowing thus to delimit the angular travel of the second rocker 20 and to define two distinct positions for the second rocker 20.
  • a pin (not shown in the figures) is provided on the plate, arranged to cooperate with the opening 20c of the second lever 20.
  • the pin forms, in cooperation with the opening 20c, means for limiting the travel of the second lever 20 when the latter pivots.
  • the meshed position between the corrector and the date ring is defined by the first end of the opening, when it comes into contact with the pin.
  • a third lever 30 is provided pivotally mounted on the plate and carrying a guide groove 34 arranged to cooperate with the pull-out piece 6.
  • the third lever 30 is arranged to cooperate with the second lever 20 and block the latter when the winding stem is in the time-setting position and thus prevent the date from being corrected when the time is corrected.
  • the third lever has a first free end 31 on which is mounted a pin 32 arranged to rest against the second lever 20 when the winding stem 1 is in the time-setting position, and a second end 33 comprising the guide groove 34 cooperating with a pin 35 secured to the puller 6.
  • the guide groove 34 has a bent shape which makes it possible to define three angular positions of the lever corresponding to the winding, date correction and time correction positions of the control stem 1.
  • the lever 30 cooperates indirectly with a jumper 9 via the puller 6.
  • the jumper 9 comprises a flexible arm 90 having three notches 9a, 9b, 9c.
  • the pull tab 6 comprises a pin 36 which cooperates with one of the notches 9a, 9b, 9c depending on the position of the rod.
  • the pull tab 6 cooperates also with the winding stem 1 by means of a pin 37 arranged to rest in a groove 38 of the winding stem 1.
  • the pull rod 6 pivots and pushes the flexible arm 90 and the pin is positioned 36 is placed in one of the notches 9a, 9b, 9c depending on the position occupied by the winding stem 1.
  • Such an arrangement makes it possible in particular to create “notches” for the different positions of the winding stem 1 and therefore to facilitate the identification of the position of the winding stem 1 by the wearer when he wishes to make a correction.
  • the operation of the movement according to the invention is as follows: in the manual winding position, as shown in the Figure 4a , the sliding pinion 4 meshes with the winding pinion 2 which meshes with the winding mechanism (not shown) to manually wind the movement.
  • the control stem 1 occupying its winding position is kinematically linked to the winding mechanism of the movement and is not kinematically linked to the drive wheel 11, nor consequently to the other time or date correction mechanisms.
  • the sliding pinion 4 translates towards the drive wheel 11 and then meshes with it.
  • the third lever 30 is also moved when the control stem 1 is pulled and allows the second lever 20 to pivot into the date correction position.
  • the control stem 1 is therefore kinematically linked to the drive wheel 11 and the first 10 and second 20 levers are positioned so that the first drive wheel 11 is kinematically linked to the date correction mechanism carried by the second lever 20 and is not kinematically linked to the minute wheel.
  • the second lever 20 is positioned so that the drive wheel 11 meshes with the connecting pinion 16 carried by the second lever 20.
  • the connecting pinion 16, integral with the correcting member 15 then drives the latter and the friction washer 18 in rotation so as to pivot the second lever 20 and then one of the correction fingers 17 cooperates with a tooth 5 of the date ring 3 and actuates the latter to correct the date.
  • the first lever 10 is positioned so that the drive wheel 11 does not cooperate with the timer. Thus the rapid date correction function is isolated from the time setting and winding functions.
  • the pull-out acts on the third lever 30 and moves it into the position for locking the second lever 20
  • the cooperation of the pin 35 in the guide groove 34 causes the third lever 30 to tilt, which moves from its rest position to its time-setting position, so as to block the movement of the second lever, at least in the direction of the date, or even completely block the lever from moving in the direction of the date ring.
  • the time-setting function is isolated from the rapid date correction and winding functions.
  • the meshing between the first drive wheel and the date display or time setting mechanisms is not permanent, so that the teeth of the different parts do not require specific cutting.
  • the invention also relates to a timepiece comprising a watch movement according to the invention.
