Definitions

  • the present invention relates to a correction mechanism for a device for displaying a time value of a timepiece. More specifically, the present invention relates to such a mechanism for the bidirectional correction of a display device of a temporal magnitude such as a date mechanism.
  • FIG. figure 1 A date display mechanism is shown in FIG. figure 1 attached to this patent application.
  • this date display mechanism is driven by a reference 2 which is integral with an hour wheel (not shown).
  • the reference 2 rotates in a clockwise direction and performs a complete revolution in twelve hours.
  • This reference 2 meshes with a date drive wheel 4 which rotates counterclockwise at the rate of one revolution in twenty-four hours.
  • This date drive wheel 4 carries a finger 6 by which it drives at a rate of one step per day a date wheel 8 which is indexed by a jumper 10 and which carries a cam 12.
  • the cam has an abrupt flank 14 which marks the passage between the date of the last day of a given month and the date of the first day of the following month, in other words between the date "31" and the date "1".
  • the date display mechanism 1 is completed by a control lever 16 provided at one of its ends with an arm 18 by which it bears against the cam 12 during normal operation, and comprising at its other end a rake 20 by which it meshes with a date display wheel 22 which carries the date indicator (not shown).
  • the control rocker 16 is pivoted at 24 while a second rocker 26 said return rocker is pivoted at 28.
  • This rocker 26 has a similar structure to that of the control rocker 16, including a rake 30 by which it meshes with the date display wheel 22.
  • the return lever 26 is constrained by a spring element 32 which tends to rotate in the clockwise direction.
  • the biasing lever 26 tends to turn the date display wheel 22 counterclockwise, which tends to turn the control lever 16 clockwise and to maintain its arm 18. support against the profile of the cam 12.
  • the return lever 26 has a probe 36 which cooperates with a circular cam 38 centered on the center of the movement and on the inside profile of which the probe 36 of the latch reminder 26 comes in support. Note that in the situation in which the date display mechanism is represented on the figure 1 , the probe 36 of the return lever 26 is located at a recess 40 that has the circular cam 38 on its inner profile.
  • the winding stem 42 is kinematically connected to the circular cam 38 via an element 44 which makes it possible to transform a linear displacement of said winding stem 42 into a pivoting movement of said circular cam 38.
  • this causes the annular cam 38 to pivot counterclockwise in a manner which does not will not be detailed here.
  • the anti-clockwise pivoting of the annular cam 38 makes it possible to move the arm 18 of the control lever 16 away from the trajectory of the cam 12.
  • the date display mechanism 1 described above is particularly well suited for use in a timepiece-type watch time zone.
  • the winding stem 42 has three stable positions, namely a neutral position in which it allows the reassembly of the movement, a first drawn position which allows the correction of the time zone indicator (It can be a jumping indicator that moves forward or backward by an entire step of one hour without the minute display being affected) and a second drawn position that allows the time setting of the watch.
  • the date driving wheel 4 must therefore be able to drive, via its finger 6, the date wheel 8 both clockwise and counterclockwise. This is done without any difficulty when the correction is made by means of the winding stem 42.
  • the winding stem 42 drives the hour wheel and therefore the return 2 which in turn drives the driving wheel of date 4 and its finger 6.
  • the indication of the date may be correct by means of the rapid corrector 48 shown in FIG. figure 1 . Indeed, by successive presses on the fast corrector 48, it is possible to increment the indication of the date in steps of one unit, passing this indication for example from "1" to "2", then from "2" to "3” and so on.
  • the hour wheel, the reference 2 and therefore the driving wheel of date 4 are substantially immobile.
  • the pawl When correcting the display of the watch in the opposite direction, the pawl is driven clockwise, which causes it to pivot about the first pivot against the action of the spring when meets a tooth of the date ring. This pivoting effect makes the ratchet pass on the teeth of the date ring without it driving it backwards.
  • the Hamilton system described above is a ratchet system that drives the date ring only clockwise and fades when the ring is corrected in the opposite direction. Said pawl is not capable of driving the date ring in both the clockwise and counterclockwise directions during the normal correction phase of the date display.
  • the ratchet system briefly described above is capable of driving the date ring only in one direction. In the opposite direction, it disappears in rapid correction phase.
  • the Citizen system described above also does not allow to drive the date plate in both directions.
  • the document EP 0 871 093 describes a timepiece according to the preamble of claim 1.
  • the present invention relates to a timepiece according to claim 1 attached.
  • the present invention provides a timepiece whose drive mechanism of a display device of a magnitude related to time is able to drive this display device both in the direction clockwise and in the opposite direction when a correction operation is to be carried out via the workings of the movement, and which is also capable of being erased when it is desired to carry out directly a correction operation of the display device .
  • This is particularly advantageous in that, even when the first correction member is engaged with the display device, it is still possible to correct the indication provided by this display device by means of the second correction member. .
  • the indication provided by the display device of a quantity related to time can therefore be corrected at any time.
  • the drive mechanism comprises a wheel carrying the finger, which finger is connected to a spring by a first pin around which it can pivot, the pivoting angle of said finger being limited by a second pin which it is secured and which is engaged in a light made in the driving wheel, the spring holding the finger in a position in which it is engaged with the toothing of a driven wheel of the display device for driving the wheel clockwise or anti-rotation. time, this spring allowing said finger to disengage from the toothing of the driven wheel during a correction of the display device by means of the second display member.
  • the drive mechanism drives the display device trailingly and the second correction member makes it possible to manually correct said display device by incrementing it in successive steps of one unit.
  • the present invention proceeds from the general inventive idea of providing a drive mechanism of a time-related display device capable of driving this display device in both clockwise and anti-clockwise directions. when it is itself driven by the movement of the timepiece, and is also capable of being erased when a manual correction of said display device is made by incrementing its indication in successive steps of a unit. Thanks to these arrangements, the present invention makes it possible to correct the indication provided by the display device at any time, even when the drive of said display device is of the trailing type.
  • the present invention will be described in connection with a date display device. It goes without saying that this example is given purely for illustrative purposes only, and that the present invention applies to any type of display device of a time-related magnitude such as the day of the week, the indication of the month of the year or the indication of the moon phases.
  • this mechanism comprises a driving wheel 52 which plays with respect to a device displaying a quantity related to the time (not shown) the same role as that held by the date driving wheel 4 vis-à-vis the date mechanism 1 shown in the figure 1 .
  • this driving wheel 52 is driven by the hour wheel of the movement of the timepiece via the reference 2, and in turn, it drives via a finger 54 the date wheel 8 of the date display device 1.
  • the finger 54 is carried by the driving wheel 52.
  • the finger 54 has an oblong opening 56 through which it is engaged on a hub 58 of said driving wheel 52.
  • a spring 60 holds the finger 54 in a position in which this finger 54 is engaged with the toothing of the date wheel 8 to drive it in the clockwise or counterclockwise direction.
  • this spring 60 also allows the finger 54 to disengage from the toothing of the date wheel 8 during a manual correction of the date indication by means of the rapid corrector 48
  • the spring 60 is disposed between the driving wheel 52 and the finger 54.
  • the spring 60 has a circular opening 62 having two diametrically opposed lugs 64a and 64b through which it is frictionally engaged on the hub 58 of said wheel In the normal operating mode, the spring 60 is stationary relative to the driving wheel 52.
  • the friction fitting of said spring 60 on said driving wheel 52, enabled by the presence of the two lugs 64a and 64b, is simply provided to allow fine adjustment of the drive mechanism 50 according to the invention as described below.
  • the finger 54 is coupled with the spring 60 by means of a pin 66.
  • This pin 66 is driven into the finger 54 but is free to pivot in an opening in the spring 60 in which it is engaged.
  • This pin 66 constitutes the pivot point of the finger 54.
  • a second pin 68 also driven into the finger 54 and which is engaged in an oblong opening 70 formed in the driving wheel 52 in which the pin 68 is free to move .
  • the pin 68 is positioned in a recess 72 provided towards the free end 74a of a substantially semi-circular elastic arm 74 of the spring 60.
  • the finger 54 must be rigid. By this is meant that the finger 54 must be able to drive the date wheel 8 clockwise as anti-clockwise without arming itself in the manner of a spring mechanism of instantaneous or semi-instantaneous type. It is also recalled that normal operating mode means the periods when the return 2 drives the driving wheel 52 either because this reference 2 is driven by the movement of the timepiece clockwise, or because this reference 2 is clockwise or counter-clockwise by actuation of the winding stem 42. In other words, in normal operation, the return 2 rotates and drives the drive wheel 52 which itself drives the date wheel 8.
  • the fast correction phase The situation is quite different in the fast correction phase.
  • the user of the watch wants to be able to increment by successive steps of a unit the indication provided by the date display device which belongs in particular to the date wheel 8 by means of the fast corrector 48.
  • the reference 2 can be regarded as substantially immobile to the extent that, driven by the hour wheel, it performs a complete revolution in twelve hours. Therefore, in the fast correction phase, the driving wheel 52 is stationary. If, at the moment when the user chooses to correct the date indication with the help of the fast corrector 48, the finger 54 is not in contact with the toothing of the date wheel 8, there is no of particular problem.
  • the present invention overcomes this problem. Indeed, when attempting to advance the date wheel 8 by means of the rapid corrector 48, it exerts on the finger 54 a thrust in the direction shown by the arrow A on the figure 2 . Under the effect of this thrust, the finger 54 which was applied against the hub 58 by the semicircular portion 56a of its oblong opening 56 moves and abuts against said hub 58 by the semi-circular portion 56b opposite the semi-circular portion 56a of its oblong opening 56. At the same time, said finger 54 pivots around the pin 66 and deviates from the trajectory of the tooth of the date wheel 8 with which it was engaged, which allows to this tooth to pass.
  • the spring 60 is mounted almost permanently on the hub 58 of the driving wheel 52, only a tool 76 engaged in an opening 78 made in said driving wheel 52 at the a notch 80 of the spring 60 for slightly moving said spring 60 relative to said hub 58 by a few degrees in the clockwise or counterclockwise direction to catch any games and synchronize the date jump with the jump of the day.
  • the spring 60 can be rigidly mounted on the driving wheel 52 if the tolerance between the jump of the date indication and the jump of the day indication is large.
  • the fast correction mechanism 48 is shown in detail at the figure 1 . It comprises in particular a quick-action push-button 82 which acts against the elastic restoring force exerted by a spring 84 kept under tension between a first pin 86 secured to the frame of the watch and a second pin 88 carried by a rocker. control 90 on which the pusher 82 acts. This control lever 90 is able to pivot around the pin 86 and carries a corrector element 92 which enters the teeth of the date wheel 8.
