Definitions

  • the present invention relates to the field of watchmaking. It relates more specifically to a device for correcting a display mechanism of a time indication, such as a date, a day of the week, a month, etc.
  • the display mechanisms of a time indication generally comprise one or more display members, such as disks or rings, rotated by a drive mechanism.
  • Correction devices for such display mechanisms are well known to those skilled in the art. They mainly comprise a winding stem arranged to occupy at least one correction position of the time indication, a pinion integral in rotation with the winding stem, a return engaged with the pinion when the rod is in the correction position and a correction mobile actuated by the return and cooperating with a first display member.
  • the set is usually mounted on a plate, dial side.
  • the corrector mobile is mounted walker between two correction positions, the passage of a correction position to the other being done by reversing the direction of rotation of the winding stem .
  • the corrective mobile is, for example, mounted on a rocker actuated by the reference.
  • the assembly formed by the reference, the rocker and the corrective mobile is located at 3 o'clock, in the vicinity of the winding stem. It has a large footprint, which makes its integration inconvenient in the case where other parts are close to the winding stem. It's the case, particularly when the plate is crossed by axes of chronograph counters located near the winding stem.
  • the space available for the correction device of the display mechanism is then greatly limited.
  • the present invention makes it possible to overcome this disadvantage, by proposing a device for correcting a display mechanism of a time indication, of which the correction-mobile toggle unit is moved towards one of the sectors 9 hours, 6 hours. or 12 hours of platinum, while freeing up useful space on the platen.
  • the corrective return frees space inside its inner circumference, which allows to house parts, for example counters axes.
  • the rocker-mobile correction unit may be substantially removed from the immediate vicinity of the winding stem, while releasing a large space to the inside of the correction mark.
  • the corrective reference surrounds all the counters axes, and moves the corrective toggle-mobile assembly to 9 hours.
  • FIG 1 there is shown a turntable 10 for a timepiece, on which are mounted, on one side, a not shown movement, of mechanical or electromechanical type, equipped with a chronograph mechanism, and, on the other side, a mechanism for displaying a time indication 12 and its correction device 14.
  • the plate 10 is traversed by a central axis 15 intended to carry display members unrepresented hours and minutes, and by two axes 16 and 18, respectively located substantially at 4 o'clock and 8 o'clock, belonging to the minutes and hours counters of the chronograph mechanism.
  • the display mechanism of a time indication 12 is of conventional type. It comprises a digital date indicator 20, formed of a ring 22 provided with an internal toothing 24.
  • the date indicator 20 is mounted on a calendar board 26, screwed to the plate 10 and provided with a clearance 28 meant for that purpose. It is positioned angularly by a jumper 29, and held axially and guided in rotation by a holding plate 30 fixed to the calendar board 26.
  • the display mechanism 12 further comprises a day display member, such as a needle, not visible on the figure 1 .
  • the display member days is mounted in the center of the plate 10, secured to a mobile 32 formed of a star of days 34 and a correction star 36.
  • the date indicator 20 and the day display member are rotated by a drive mechanism 38 located at 11 o'clock, comprising a driving wheel 40, formed of a wheel 42 and a finger 44 integral in rotation.
  • the finger 44 cooperates on the one hand with the toothing 24 and, on the other hand, with the star of days 34.
  • the wheel 42 is itself driven by a pinion 46, kinematically connected to the movement by an axis passing through the plate 10.
  • the display mechanism 12 thus described is intended to take place behind a not shown dial. It allows the display of the date, through a first wicket practiced in the dial, and the corresponding day of the week, through the day hand cooperating with indications of days affixed to the dial.
  • the correction device 14 of the display mechanism 12 conventionally comprises a winding stem 50 mounted guided in rotation in the 10.
  • a sliding pinion 52 is rotatably mounted on the winding stem 50, movable between a correction position A and a winding position B. In the correction position A, it meshes with a first intermediate return 54, mounted freely in rotation on the plate 10, and itself engaged with a second intermediate gear 56 mounted free to rotate on the calendar board 26.
  • the second intermediate gear 56 is engaged with a corrector 58 formed of a ring 60 provided with an internal toothing 62.
  • the corrector 58 is rotatably guided by its outer circumference, on the calendar board 26.
  • a clearance 63 is provided in the calendar board 26. It is, in addition, held axially by three screws 64a, 64b, 64c distributed angularly at its periphery. Its diameter is close to the diameter of the date indicator 20, and it is positioned substantially centered, around the axes 15, 16 and 18, of the various elements of the drive mechanism 38, and the correction device 14.
  • the corrective switch 58 actuates a double corrector 66 mounted at 9 o'clock on the calendar board 26, and formed of a corrective mobile 68 mounted on a flip-flop 70.
  • the flip-flop 70 is pivotally mounted between a first and a second correction position, respectively A 'and B', about a pivot axis XX perpendicular to the plate 10. It comprises a board 72 mounted on a control wheel 74, axis of rotation coinciding with the pivot axis XX, in The control wheel 74 is further rendered partially integral with the board 72 by means of friction 76.
  • a pinion 78 is mounted on the board 72, integral in rotation with the control wheel 74.
  • the corrective mobile meshes with the toothing 24 of the date indicator 20, and in the second correction position B', it meshes with an intermediate star 80; -even in taken with the correction star 36.
  • the mobile corrector 68 is mounted walker in an oblong hole made in the calendar board 26, according to a technique well known to those skilled in the art.
  • the correction device 14 thus described has two important advantages over a conventional device.
  • space is released at its center. This space is occupied, in this case, by parts belonging to the drive mechanism 38, to the correction device 14 itself, and by the axes 15, 16 and 18.
  • the corrector 58 allows to move the double corrector 66, which, due to the presence of the axis of the minute counter 16 to 4 hours, can not be mounted in the vicinity of the winding stem 50.
  • the double corrector 66 is moved at 9 o'clock, but it could be also at 6 o'clock or at 12 o'clock, or at any location of the free plate 10 to receive it. In addition, the double corrector 66 is moved relative to the plate 10, without losing any useful space thereon.
  • This arrangement of the correction device 14 is advantageous for a plate 10 pierced with several axes, virtually regardless of the position of these axes. It will be seen later that other arrangements of the correction device 14 may be envisaged for particular axis positions.
  • the operation of the correction device 14 is as follows.
  • the winding stem 50 is actuated clockwise, the sliding pinion 52 being in the correction position A, the first intermediate return 54 is driven in the counter-clockwise direction, and it drives itself, the second intermediate return 56 clockwise.
  • the latter meshes with the corrective wheel 58, which rotates clockwise, and in turn drives the control wheel 74 of the latch 70 in the clockwise direction.
  • the control wheel 74 rotates the board 72 under the effect of the friction 76, until the corrective mobile 68 meshes with the date indicator 20.
  • the control wheel 74 then disengages from the board 72, and actuates the corrective mobile 68 via of the pinion 78.
  • the correction mobile 68 corrects the date indicator 20 by rotating it counterclockwise.
  • the correction device 14 illustrated in figure 5 differs from the device illustrated in Figures 1 to 4 , in that the corrective return 58 is of a diameter smaller than the radius of the date indicator 20 and in that it is off-center with respect to the plate 10, so as to occupy essentially the quarter situated between 3 hours and 6 hours.
  • the space released at its center is essentially occupied by the counter axis 16 minutes.
  • the double corrector 66 is located at 6 o'clock, that is to say between the axes of the counters 16 minutes and 18 hours.
  • the toothing 24 of the corrector 58 is located on its outer circumference and not inner, and the rotation guidance is ensured by its inner circumference. This arrangement is suitable for a plate 10 pierced with a central axis 15, and two off-center axes 16 and 18, respectively at 4 o'clock and at 8 o'clock.
  • the correction device 14 illustrated in figure 6 differs from the above, in that the diameter of the corrector 58 is smaller than the diameter of the date indicator 20, but greater than its radius.
  • the corrective return 58 is, furthermore, off-center with respect to the plate 10, so as to occupy essentially the half between 9 hours and 3 hours.
  • the central axis 15 is included in the space released at its center.
  • the toothing 24 is external and not internal. The arrangement thus described is suitable for a plate pierced with four axes 15, 16, 18, 82 located respectively at the center, at 4 o'clock, at 8 o'clock and at 6 o'clock.
  • the rotational guidance of the corrector 58 is made by its outer or inner circumference.
  • the corrective return 58 may be, for example, formed of a ring 60 provided with a circular rib, engaged in a groove made in the calendar board 26.
  • the correction device 14 does not include a second intermediate reference 56 in the variants illustrated in FIG. Figures 5 and 6 . It will be understood, in the same way, that the first intermediate return 54 is not essential to the correction device 14, and that the corrector 58 can be mounted in direct connection with the sliding pinion 52.
