Definitions

  • the present invention relates to a timing mechanism for a timepiece and more particularly to such a mechanism comprising a date display, a display of the months, and a rapid corrector of months.
  • the patent document CH 697'662 describes a timing mechanism for a timepiece.
  • This mechanism is more precisely a perpetual calendar mechanism. It includes a date display and a display of the month.
  • the mechanism described in this prior document also includes a date corrector and a month corrector respectively for manually correcting the indication of the date and that of the month. These correctors are arranged to be respectively actuated by two pushbuttons for incrementing a step, one, the indication of the date and the other, that of the month.
  • one of the advantage of the described mechanism is that it makes it possible to advance the indication of the month using the corrector provided for this purpose, without affecting the indication of the date. In most cases, this arrangement makes it more intuitive to set the calendar date. However, this is not always the case. By For example, if the month corrector is activated while the calendar shows January 30th, the calendar will change to February 30th.
  • the patent document EP 1 004 947 discloses a quick date correction mechanism comprising an actuator accessible from the outside of the watch and which is arranged to drive the date star rotating by means of a train.
  • the multiplication ratio of the gear train is sufficient for a movement of the actuator causes the date star to a value corresponding to more than a month.
  • the high multiplication ratio renders the correction mechanism all the more inaccurate. It therefore becomes very difficult for the user to release the actuator near the desired date without risking exceeding the latter.
  • An object of the present invention is to overcome the aforementioned drawbacks. It achieves its purpose by providing a calendar mechanism according to the appended claim 1.
  • the stop may occupy either an inactive position, in which it does not intercept the trajectory of the rotary stop, or an active position in which it blocks the mobile of 31 in an angular position corresponding to the indication the first day of the month.
  • the month quick corrector comprises a rake 3 with a toothed sector 5 at one of these ends and a first control pin 7 at the other end.
  • the rake is pivotally mounted about an axis 9 arranged close to the end bearing the pin 7.
  • the toothed sector meshes with the pinion of a first mobile 11, and the wheel of this first mobile meshes with a cogwheel unique 13.
  • the one-way train comprises an input wheel 15 and an output wheel 17 which are coaxial and which are pivotable relative to each other.
  • the output wheel 17 carries a coaxial ratchet (not shown) which is sandwiched between the input wheel and the output wheel.
  • a pawl 19 is pivoted on the board of the input wheel 15. This pawl is biased against the periphery of the ratchet by a spring 21.
  • the skilled person will understand that the pawl is arranged to cooperate with a tooth of the ratchet when the Inlet wheel rotates clockwise and to slide against the ratchet when the input wheel rotates counterclockwise.
  • the output wheel of the one-way gear 13 meshes with a pinion 23 which is part of the mobile thirty-one (the latter being generally referenced 31).
  • the quick month corrector of the present example is intended to be operated manually via a multifunctional coaxial corrector device (not shown) which may advantageously be of the same type as that described in the patent document.
  • EP 1 939 699 in the name of the plaintiff.
  • the patent document EP 1 939 699 is incorporated by reference. It will be understood, however, that many other manual control devices known to those skilled in the art may also be suitable for actuating the month rapid corrector of the present invention. Be that as it may, this description does not give details of the manual control device. Indeed, the characteristics of the latter do not bear directly consequence for the implementation of the invention.
  • the internal bearing surface of the control mechanism pushes the first control pin 7 in the direction of the arrow (a) ( figure 1 ), which causes the pivoting of the rake 3 about the axis 9.
  • the length of the stroke of the internal bearing surface of the control mechanism is considerably less than the length of the toothed sector 5.
  • the lever effect allows the entirety of the teeth of the sector 5 to cooperate with the pinion of the mobile 11. The latter is thus driven in the counterclockwise direction.
  • the control pin 7 is biased by a spring (not shown) in the opposite direction to the arrow (a) of the figure 1 .
  • the mobile 11 When the mobile 11 rotates counterclockwise, it drives the input wheel 15 of the one-way train 13 in the clockwise direction. Under these conditions, the output wheel 17 is integral in rotation with the input wheel and also rotates clockwise. When the mobile 11 turns back clockwise, it drives the input wheel counterclockwise. Under these conditions, the one-way train disengages and the output wheel is not driven. Finally, as has already been said, the output wheel meshes with the pinion 23 of the mobile of 31. It will therefore be understood that the actuation by the user of the button of the multifocal coaxial corrector has the effect of driving the mobile of 31 counterclockwise.
  • the gear ratios are chosen according to the length of the stroke of the control mechanism, so that a single press of the button is sufficient to advance a complete revolution of the mobile 31.
  • the figure 1 also shows a lever 29 which is pivotally mounted about an axis 33 and which carries, at one end, a bifurcated hook 35, and at the other end, a spout 37.
  • the shape of the lever 29 is adapted to allow it to cooperate with a latch 39 which is itself pivotally mounted on an axis 41.
  • lever 29 and the latch 39 are respectively biased in the direction of the arrows (b) and (c) by two springs (not shown). As will be seen further, lever 29 and latch 39 are both movable between an inactive position and an active position.
  • the figure 1 further shows that the hub of the wheel 25 carries a pin (or a stud) 27 in the eccentric position. The pin 27 is arranged to cooperate with the hook 35 only when the hook is in the active position.
  • the function of the elements of the rapid correction of months which have just been described is to stop the fast advance of the date mobile as soon as it reaches the angular position corresponding to the indication of the first day of the month.
  • the operation is as follows. As long as the month quick corrector is not actuated, the rake 3 is in its rest position shown in FIG. figure 1 . As can be seen, the spout 37 of the lever 29 is then resting against the rake. The rake opposes the pivoting of the lever in the direction of the arrow (b) and keeps it in the inactive position. In this position, the hook 35 is outside the circular path of the pin 27. The hook does not interfere with the rotation of the mobile 31.
  • the lock 39 is also in abutment against the rake.
  • the rake thus also keeps the lock inactive position.
  • the rake pivots releasing the lever 29 and the latch 39 which are then free to pivot respectively in the direction of the arrows (b) and (c) to enter the active position.
  • the hook 35 serves as a stop arranged to intercept the path of the pin 27.
  • the pin 27 thus plays the role of a rotary stop which is arranged to cooperate with the stop 35. It will be further understood that, thanks to the presence of the lock 39, the rotary stop 27 is unable to push back the stop 29 in the inactive position. The collision of the rotary stop with the stop thus has the effect of stopping the advance of the mobile of 31.
  • the lever 29 is also positioned relative to the pin so as to immobilize the mobile of 31 in the angular position corresponding to the indication of the first day of the month.
  • the rake 3 returns to its starting position by pushing the lever 29 and the latch 39 which return to the inactive position.
  • the pin 27 could in fact be mounted directly on the mobile of 31.
  • the calendar mechanism of the invention comprises monthly drive means actuated by the mobile 31 and provided to increment by one step the indication of the month at the end of each month.
  • the monthly drive means comprise an eccentric 43 concentric and integral with the mobile 31, an instantaneous rocker 45 mounted to pivot about an axis 46, a spout 47 integral with the instantaneous rocker, a rocking spring instant 49 arranged to recall the tip of the rocker against the periphery of the eccentric, and an instantaneous pawl 51 pivoted on an axis 53 arranged at a bend of the rocker, the pawl 51 being biased against the asymmetric sawtooth a ratchet toothing that carries the mobile twelve by a spring 55 (the mobile of twelve being generally referenced 12).
  • the means monthly training still include a jumper 59 arranged to cooperate with the ratchet toothing of 12.
  • the shape of the eccentric 43 is such that the birth and the vertex of the curve of the eccentric are superimposed.
  • the eccentric is arranged so that the angular position of the mobile 31 at the moment when the spout 47 of the instantaneous rocker 45 can drop without transition from the vertex to the birth of the curve of the eccentric corresponds approximately at the transition between the 31 th day of a month and the first day of the next month.
  • the beak is at the birth of the curve.
  • the bill climbs the curve day by day by gradually raising the instant rocker.
  • the pivoting of the instantaneous rocker has the effect of sliding the pawl 51 against the ratchet toothing of the mobile 12.
  • the spout 47 reaches the top of the curve and, pushed by the spring 49, suddenly drops to end up at the birth of the curve.
  • the spout suddenly brings back the instantaneous rocker and the pawl 51.
  • the pawl 51 hooks one of the sawtooth teeth ratchet and thus advances a pitch of the mobile 12, this which has the effect of incrementing by one month the indication of the month.
  • the monthly training means that have just been described are arranged to increment the mobile of 12 each time the mobile 31 passes from the last day of a month to the first day of the following month.
  • the monthly training means are actuated both when the mobile of 31 passes from one month to another driven by the movement, than when it is done by the rapid corrector of the months.
  • the drive means that have just been described are of the so-called “instantaneous” type. Those skilled in the art will understand, however, that the monthly drive means of the calendar mechanism according to the invention could equally well be of the "trailing" type or of the "half-instantaneous" type.
  • the date corrector device of the calendar mechanism of the present example will now be described with reference to the figure 4 .
  • the date corrector device is manually operable and is intended to drive the mobile 31 in increments of one day.
  • the date corrector comprises a date corrector lever 61 pivoted on an axis 65, a date control pin 63 mounted on one end of the lever 61, a spout 67 biased against the ratchet toothing of 31 by a spring 71, and finally a jumper 69 arranged to cooperate with the ratchet toothing of 31.
  • the date corrector of the present example is intended to be operated manually by the same multifunctional coaxial corrector device (not shown) which also actuates the rapid corrector of months. It will be understood, however, that many other manual control devices known to those skilled in the art may also be suitable for actuating the date corrector of the present invention. In particular, according to a variant of this example, the date corrector and the month quick corrector could be actuated respectively by two separate manual control devices.
  • the internal bearing surface of the control mechanism pushes the date control pin 63 into the direction of the arrow (a) ( figure 4 ), which causes the lever 61 to pivot about the axis 65.
  • the spout 67 which is fixed at one of its ends, moves along a substantially tangent path to the ratchet teeth of the mobile 31.
  • the spout 67 hooks one of the saw teeth of the ratchet toothing and thus advances by one step the mobile of 31 by raising the jumper 69.
  • the one-step advance of the mobile of 31 has the effect of incrementing by one day the indication of the date. Note that rake 3 month fast corrector remains in the rest position during use of the date corrector. Thus, the lever 29 remains in the inactive position and the date corrector is still operative, even when the mobile 31 has reached the angular position corresponding to the indication of the first day of the following month.
  • FIGS. 5, 6 and 7 are respectively side, top and perspective views of a portion of a rapid correction device according to a second embodiment of the invention. These three views show in particular a wheel 125 whose cylindrical axis 126 carries a lug 127 and a projection 145.
  • the figures also show an anchor 135 mounted for pivoting about an axis 133 and one of the legs 147 plays the role of cam follower lever, and the other leg 143 acts as a stop lever.
  • the function of the elements of the fast corrector which have just been enumerated is to stop the fast advance of the date mobile as soon as it reaches the angular position corresponding to the indication of the first day of the month.
  • the operation is as follows.
  • the wheel 125 is kinematically linked to the mobile of 31 (not shown on the Figures 5, 6 and 7 ) so that it rotates at the same speed as the latter.
  • the wheel 125 is arranged to turn clockwise (as indicated by the arrow d) when the mobile of 31 is incremented.
  • the lug 127 and the protrusion 145 are offset by about 180 °.
  • a careful examination of the figures further reveals that the lug and the projection are not only angularly offset about the axis 126, but are also offset in height. Indeed, the lug 127 is placed quite low, in the immediate vicinity of the wheel 125, while the projection 145 is placed higher, close to the upper end of the cylindrical axis.
  • the distal ends of the two legs of the anchor 135 are also offset in height.
  • the height of the end of the tab 147 corresponds to that of the projection 145 and the height of the end of the tab 143 corresponds to that of the pin 127.
  • the end of the tab 147 plays the role of a probe 149, and it is arranged to be raised by the projection 145 at each new turn of the wheel 125.
  • the tab 147 causes the pivoting of the anchor 135 about its axis 133. This pivoting has the effect of bring the other tab 143 of the anchor into active position. In this position, the end 151 of the lug 143 intercepts the trajectory of the lug 127, so that these two elements can cooperate, the lug playing the role of rotating stop and the end of the lug 143 playing that of a judgment 151.
  • the position at the instant the projection 145 rotates the anchor 135 corresponds to the indication of the 27th day of the month.
  • the mobile 31 is shown one day later, in the angular position corresponding to the indication of the 28th day of the month. It can be seen that turning, the projection 145 has now passed the probe 149. As for the lug 127, it has not yet arrived at the stop 151.
  • a small spring (not shown ) is arranged to recall the anchor 135 in the direction of the arrow (d, figure 6 ).
  • the function of the small spring is to maintain the feeler 149 against the surface of the cylindrical axis 126. It can be seen on the Figures 6 and 7 after the protrusion has passed, the cam follower lever 147 and its probe have lowered again under the effect of the small spring. This movement is accompanied by a pivoting of the anchor 135 about its axis 133, so that the stop lever 143 returns to the inactive position, away from the circular trajectory of the lug 127.
