Definitions

  • the present invention relates to a calendar mechanism in a watch, having first and second indicators each associated with a mobile rotary equipped with a toothing, a rocker drive provided with two nozzles arranged to act respectively on the toothing associated with the first or the second indicator, according to the direction of pivoting of the rocker training, to make step forward the corresponding indicator, a drive wheel making a turn through day and provided with a drive element which cooperates with a cam surface of the rocker training to rotate this rocker every day in a sense and in the other from a neutral position and thus act said beaks on said teeth, and manual correction means for advancing step by step the first and second indicators independently of each other.
  • a mechanism of this kind operates daily a date indicator and a day indicator in a clock, thanks to a rocker with two arms whose ends each carry a ratchet cooperating with a peripheral toothing of the indicator disc concerned.
  • This flip-flop has a hole whose serpentine periphery forms a cam surface and in which circulates a cam follower carried by a wheel that makes one turn per day. he This results in a great simplicity of the drive mechanism of the indicators.
  • the correction of the indications of the calendar requires two correction, independent of the daily training and associated each with the indicator respective, which increases the overall size of the mechanism and requires two manual correction organs.
  • Patent FR 1 517 236 describes a calendar mechanism with indicators of date and day which is usable in a watch and which also includes a common drive element for both indicators, this element having a hole of complex shape in which turns a finger coach.
  • the coaching element performs a combination of sliding movements and swivel.
  • a date correction device by means of the time-setting rod, which is completely independent of the element drive.
  • patent CH 584 926 discloses a correction mechanism common day and date indicators from the winding stem of a shows, while the daily training of these indicators is carried out by other organs.
  • the common element that sometimes attacks the first indicator and sometimes the second performs a combination of sliding and pivoting movements.
  • the present invention aims to simplify the construction and control of the calendar mechanism, taking into account the necessary bodies for the correction of indications.
  • a basic idea of the invention is to use certain common bodies for the daily training of the two indicators and for the individual manual correction of each indicator.
  • the present invention provides, in a mechanism of the kind indicated in the preamble above, that the manual correction means act on the rocker drive so as to rotate selectively in one direction or in the other to advance the corresponding indicator by one step.
  • Manual correction means comprise a correction wheel driven by rotation selectively in one direction or the other by a control rod by a correction wheel, the correction wheel having one or more salient elements arranged to lean against a nose of the rocker of training so as to rotate it in one direction or the other according to the direction of rotation of the correction wheel.
  • the most bulky element of the kinematic chain driving the two indicators namely the rocking drive, is advantageously reused for correcting indications.
  • its actuation in both directions to from the same manual controller to selectively correct one or the other of the indicators also represents an economy of means.
  • the control rod already present in the watch the number and the clutter elements of the correction mechanism are further restricted and manipulations are easy.
  • FIG. 1 schematically represents the front face of a fitted watch of a calendar mechanism according to the invention, comprising in this example a date indicator and a moon phase indicator.
  • FIG. 2 is a view in transparency of the calendar mechanism, in a position of equilibrium after the daily progress of the date indicator.
  • Figures 3 to 7 show successive positions of the mechanism of calendar to step forward the date indicator.
  • Fig. 8 shows a position of the calendar mechanism at the moment he steps forward the moon phase indicator.
  • the wristwatch whose dial 10 is seen in FIG. time analog, with a hour hand 1, a minute hand 2 and a second hand 3 which are driven by a clockwork movement of any type.
  • the watch further includes a calendar display comprising in this case a date indicator, formed by a rotating needle 4 in front of a graduation 5 to thirty-one positions, and a moon phase indicator, formed in a conventional manner by a disk 6 rotating behind a window 7 of shape special.
  • FIG. 1 schematically shows also the rod of manual control 8 of the watch, provided with a ring 9 on the outside of the box.
  • FIG 2 the elements of the calendar mechanism are seen from the opposite to the dial and are shown in transparency to facilitate the comprehension.
  • a date star 11 having a set of teeth 11a of thirty-one teeth forms a rotational mobile with the needle 4 shown in Figure 1. Its positions successive ones are held by means of a jumper 12 supported by a spring 13.
  • moon star 14 having a tooth 14a of fifty-nine teeth forms a mobile rotating with the moon disk 6. Its successive positions are maintained by means of a jumper 15 shouldered by a spring 16.
  • Each of the stars 11 and 14 turns one step each day in the direction of arrows A and B, thanks to a drive wheel 20 which makes one turn a day and acts on a training rocker 21 having a spout 22 arranged to advance the star of date 11 and a spout 23 arranged to advance the moon star 14, so that each star advances enough so that its tooth lifts the corresponding jumper pass on the other side of the jumper.
  • the drive of the wheel coach 20 is meshing on the wheel 25 hours of movement watchmaker, which is attached to the hour hand 1 and makes a turn in twelve hours.
  • the rocker 21 is pivotally mounted about the axis 26 of the wheel hours 25, that is to say the central axis of the watch movement, which simplifies significantly the implementation of the elements of the mechanism described here.
  • the latch 21 is made of a single plate-shaped piece and comprises a spring 27 in the form of a wand whose end is wedged between two fixed elements 28, which maintains resiliently latch 21 in its neutral position shown in Figure 2, where its points 22 and 23 do not interfere with stars 11 and 14.
  • Nozzles 22 and 23 are disposed on opposite sides of a first arm 30 of the latch 21.
  • the latch 21 On the other side of its pivot axis 26, the latch 21 has a second arm 31 wider, having a relatively large hole 32 whose circumference forms a cam surface 33 having two bumps 34 and 35 lying on two mutually opposite parts of the cam surface.
  • the second arm of the rocker 21 further comprises, on its outer contour, a nose 36 whose function will be described later.
  • the driving wheel 20, which is along one side of the rocker 21, comprises two projecting elements which are engaged in the hole 32 of this rocker, namely a drive pin 38 and a cam 39 said to correction.
  • the pin 38 is at a distance from the center of the wheel 20 and co-operates with the two bumps 34 and 35 of the cam surface 33 to pivot the rocker 21 each day once in one direction and once in the other, so that the beaks 22 and 23 advance the calendar indicators. Outside the two sectors where bumps 34 and 35 are located, the cam surface 33 is quite radially away from the circular path of the pin 38 so that we can swing the rocker 21 without touching this pin. In other words, as long as the pin 38 is not in the vicinity of one of the bosses 34 and 35, the latch 21 can rotate under the effect of correction means which will be described later.
  • manual means of correction 40 are arranged to produce the same pivoting movements of the latch 21 than those produced by the pin 38 of the drive wheel 20.
  • the user actuates the correction means 40 from the control rod 8.
  • These means comprise a return lever 42 which carries a wheel of mobile return 43 arranged to engage a fixed return 44 when the rod 8 is in a first drawn position, a position in which a rotation of the rod 8 in one way or the other rotates the wheel 43 in a corresponding direction.
  • the rocker 42 pivots so that the wheels 43 and 44 are no longer engaged.
  • the correction means 40 further include a correction flip-flop 46 in the form of a bent lever, one end of which is pivotally mounted at 47 while its other end is provided with a cam follower formed by a pin 48 which tends to rest against the cam 39 of the drive wheel 20 under the effect of a spring not shown.
  • the correction rocker 46 carries a correction wheel 50 capable of meshing with the fixed return 44 and provided with one or more projecting elements such as pins 51, for pushing the nose 36 of the rocker 21 in one direction or the other as shown respectively the arrows C and D, and thus rotate the rocker in the desired direction to act the spout 22 on the toothing 11a or the spout 23 on the toothing 14a, in order to correct the indicator concerned.
  • the latch 21 thus performs the correction of a indicator in the same way as the daily training of this indicator.
  • the cam 39 of the drive wheel 20 acts on the pin 48 of the rocker driver 46 so as to move this rocker between a first position, represented in FIG. 2 and in which the correction wheel 50 is in contact with the reference 44 of the correction train, and a second position in which the wheel of correction 50 is released from the reference 44.
  • the cam 39 has two protruding circular sectors 52 and 53, radius large enough to repel the flip-flop 46 to the first position mentioned above. Between these two sectors, the cam 39 has two recesses that allow the latch 46 to take its second position, so that the correction wheel 50 emerges from the reference 44 and can not therefore no longer be driven by the manual control rod 8. This is to prevent and a manual correction as the pin wheel 38 of the wheel coach 20 can come into contact with one of the bumps 34 and 35 of the rocker 21, which would make manual correction impossible.
  • Figure 3 shows the state of the calendar mechanism around 20:30.
  • the projecting sector 53 of the cam 39 maintains the correction lever 46 in its first position allowing the correction, while the pin 38 of the wheel 20 is enough spaced from the cam surface 33 of the latch 21 to allow it to rotate for correction.
  • Figure 4 shows the situation around 22:30, where the pin 38 will enter contact with the cam surface 33 near the bump 34.
  • the pin 48 then drops along a flank of the salient sector 53, the correction lever 46 pivots and the wheel correction 50 is cleared from footnote 44, so that a correction of the becomes temporarily impossible.
  • the daily advance of the moon indicator is illustrated in Figure 8 and produces the same movements of the correction rocker 46 as those who come to be described with reference to Figures 2 to 7.
  • the action of the pin 38 pushing back the hump 35 of the cam surface 33 rotates the rocker 21 in the direction of the arrow G, which is opposite that of the arrow E, so that the spout 23 of the rocker advance the moon star 14 enough to that the jumper 15 passes on the other side of a tooth 14c of this star and completes the rotation of a step once the latch 21 returns to its neutral position.
  • the pin 48 of the correction lever 46 follows a hollow of the cam 39, so that the correction wheel 50 remains clear of the pinion 44 and that a correction of the calendar is temporarily impossible.
  • one of the indicators may indicate the day of the week, being associated with a star whose number of teeth is a multiple integer of seven, or indicate another quantity such as the number of the week, month or year.
  • the indicator is not necessarily solidary of the corresponding star, but may be associated with it by a appropriate transmission.
  • the date star 11 can lead by meshing a date ring whose indications appear in a window.
  • the training rocker 21 drives directly such a ring.
