Definitions
- the present invention relates to a perpetual calendar mechanism or for a timepiece such as a wristwatch.
- Perpetual or annual calendar mechanisms include generally a rocker drive carrying a small ratchet cooperating with a calendar wheel with 31 teeth of a mobile date for the passage of a day to next within a month and for the last day of a month from 31 days to the first day of the following month and a large ratcheting cooperating with a snail correction cam of the date mobile for correction end-of-month days of less than 31 days.
- the drive of the date mobile by the small and big pawns at each passage from one day to the next is tra ⁇ nant, that is to say that it is carried out slowly, generally over a period of time of a few hours. During this period, the day of the current day gradually its place on the day of the following day in the box office display of the date on the dial of the watch. This solution is not very satisfactory because it affects the display accuracy and aesthetics of the watch.
- the drive of the date mobile by the small and large pawls at each passage from one day to the next is instantaneous.
- the indication of the date on the dial changes instantly at midnight, which is significant.
- a significant risk exists that at the end of the transition from the last day of a month of less than 31 days to the first day of the following month, the mobile date continues its movement under the effect of its inertia, thus giving an erroneous indication of the date. This risk is especially present when going from 28 February to 1 March of calendar where the mobile must perform instantly jump four steps.
- the present invention aims to remedy the aforementioned drawbacks of known perpetual or annual calendar mechanisms, or at least mitigate, and proposes for this purpose a date mechanism according to the annexed claim 1, particular forms of implementation of this mechanism being defined in the dependent claims.
- the perpetual calendar mechanism according to the invention is mounted on a plate 1 intended to be placed in a box of shows between the movement and the dial.
- This mechanism includes a date finger 2, a rocker of date 3 and a correction lever 4.
- the latches 3, 4 are mounted around the same pivot axis 5 but are free to rotate one by report to the other.
- the date finger 2 is driven continuously in the opposite direction hour and minute hands of the watch at a rate of one turn per day by a pin 6 secured to a wheel of 24 hours 7 meshing with a wheel 12 hours 8 fixed to the hour wheel of the watch.
- the finger of date 2 cooperates every day, from a certain time, with a finger 9 (see Figure 4) of the calendar rocker 3 and a finger 10 (see Figure 5) of the correction flip-flop 4 to gradually raise these two flip-flops 3, 4 to against the action exerted on the calendar rocker 3, respectively on a pivoting shuttle 11 cooperating with the correction lever 4, by means of respective return springs 12, 13.
- the calendar rocker 3 comprises, besides the finger 9, a first small ratchet 14 and a second small ratchet 15 which, when passing from one day to the next, cooperate respectively with a date star 31 teeth 16 and a star of the days to seven teeth 17 to make them turn instantly one step.
- the star of days 17 carries an indicator hand 18 associated with a zone displaying days of the week 19 on the watch face ( Figure 6).
- the angular position of the date star 16 and that of the star of the days 17 are indexed by jumpers 20, 21, respectively.
- the correction lever 4 has at one of its ends a rake 22 engaged with a corresponding rake 23 of the pivoting shuttle 11 and at another end a probe consisting of a finger 24 in which is fixed a probing pin 25 which, in the rest position of the correction lever 4, is in contact with a 26-month cam or a leap year cam 27 ( Figure 5).
- Each latch 3, 4 extends partly on one side of the pivot axis 5 and partly on the other side of the pivot axis 5.
- the probe 24-25 is located on the side opposite to that of rake 22 and finger 10.
- the shape of each latch 3, 4 is advantageously chosen so that the center of gravity of the rocker 3, 4 is substantially on the pivot axis 5. In this way, the mechanism is made less sensitive to shocks.
- one or more ball bearings can be associated with the pivot axis 5 of the latches 3, 4 to reduce the coefficients of friction.
- the date star 16 is integral with a 31-tooth calendar wheel 28, a wheel units 29 to 29 teeth plus an empty space 29 'occupying the place of two consecutive teeth, a wheel of tens to four teeth 30 and a snail correction cam 31.
- the set formed by the date star 16, the date wheel 28, the wheel of the units 29, the wheel of the tens 30 and the correction cam 31 will be called "mobile date" in the rest of this description.
- the wheel of the units 29 is engaged with a pinion of the units with ten teeth 32 carrying a disk of the units 33 on which is written a sequence of numbers 0 to 9 large format representative of the date units.
- the wheel of tens 30 cooperates with a pinion of tens to eight teeth 34 carrying a disc of tens 35 on which are written two consecutive series of numbers 0 to 3 of large format representative of the tens of the date.
- the pinions 32, 34 are each subjected to the action of a jumper 36, 37, respectively.
- the records of units and tens 33, 35 are juxtaposed and allow the display of the date in two large respective windows 38, 39 formed in the dial of the watch ( Figure 6).
- the gear formed by the wheel of the units 29 and the pinion of the units 32 is shown in detail in FIG. 7.
- the teeth of the wheel 29 and the pinion 32 have an epicycloidal shape and each tooth of the wheel 29, when it is aligned with the imaginary line passing through the respective centers of the wheel 29 and the pinion 32, is centered in an interlock of the pinion 32, and vice versa.
- This arrangement of the teeth of the wheel of the units 29 and the pinion of the units 32 makes it possible at the same time to increase the depth of penetration of these toothing and to lock the date wheel 16, 28-31 in its angular position relative to the pinion.
- the shuttle 11 ( Figures 2 and 5) is pivotally mounted about the same axis that the tens pinion 34 and the tens disk 35 but is free in rotation with respect to this pinion 34 and this disk 35.
- a large articulated pawl 40 on the shuttle 11 cooperates with the correction cam 31 to move so trainante the date mobile 16, 28-31 of one or more steps according to the angular position of months cam 26 or leap year cam 27 detected by the probe 24-25 of the correction lever 4 during the passage of the last day of a month of less than 31 days on the first day of the following month.
- the date wheel 28 is engaged with an intermediate wheel of date with 31 teeth 41 mounted around the same axis as the gear of the units 32 and the disk of the units 33 but free in rotation with respect to this pinion 32 and this disc 33 (FIGS. 1, 2, 3).
- the intermediate date wheel 41 meshes with a pinion gear 42 which itself meshes with a wheel of 31 teeth 43.
- This wheel of the month 43 drives a month disc 44 coaxial with the wheel months 43 and having a finger 45 on its periphery, via a pin 46 integral with the wheel 43 and located in a hole 46 'of the disc of the months 44 larger than it ( Figures 2, 3, 5).
- the finger 45 of the disc of months 44 cooperates at the end of each month with a pinion of months to 12 teeth 47 to drive it a step so it performs a turn per year.
- This pinion of the months 47 which is integral with the cam of the months 26, carries a month indication needle 48 associated with a display area of month 49 on the dial of the watch ( Figures 3, 6) and is subject to the action of a jumper 47 '(visible in Figure 2).
- the pinion of the months 47 leads a wheel of 48 months 50, to 48 teeth, mounted around the same axis as the 43 month wheel and the 44 month disc but free in rotation with respect to these, to drive it at the rate of one turn in four years.
- a first 30-tooth year wheel 51 is integral with the 48-month wheel 50.
- a second 30-tooth year wheel 52 mounted around the same axis as the pinion of the months 47 but free in rotation with respect to this pinion 47 is driven by the first year wheel 51.
- This second year wheel 52 which is integral leap year cam 27, carries a year indication needle leap 53 associated with a corresponding display area 54 on the dial of the watch.
- the cam of the months 26 has a periphery whose radius, variable, depends on the number of days in the months of the year, the angular position of this cam 26 defining the current month.
- the periphery of the cam 26 has more precisely (see Figure 5) large radius parts 55, corresponding to the months of 31 days, parts of intermediate radius 56, corresponding to the months of 30 days, and a part of small radius 57 (visible in Figure 2), corresponding to the February of a non-leap year (28 days).
- the leap year cam 27 has on its periphery a single boss 58 ( Figure 5) associated in the month of February leap years.
- the bump 58 of the year cam leap 27 occupies, during the month of February of each leap year, a angular position in which the angular sector defined by the hump 58 includes that defined by the lower part 57 of the periphery of the cam of the months 26 and, during the month of February of each non-leap year, an angular position wherein the aforementioned angular sectors are separated.
- the 24 hour wheel 7 carrying pin 6 training date finger 2 meshes with a second 24 hour wheel 59 mounted around the same axis as the star of days 17 but free in rotation with respect to this star of days 17.
- This second wheel of 24 hours 59 carries a day / night indicator hand 60 associated with a zone corresponding day / night display 61 on the dial of the watch, concentric with the display area of the days of week 19 ( Figure 6).
- the perpetual calendar mechanism comprises also a device for displaying the moon phase.
- This device includes (see FIGS. 1, 2, 9A) a moon gear 62 driven by the date finger 2 to one step per day and subjected to the action of a jumper 63.
- the moon gear 62 carries a pinion gear 64 which meshes with a second pinion gear 65 meshing with a 66 window wheel.
- a third idler gear 67 is secured to the second pinion gear 65 and meshes with a moon wheel 68.
- the meshing ratios between the first and second idler gears 64, 65, between the second idler gear 65 and the box wheel 66 and between the third idler gear 67 and the moon wheel 68 are such that the window wheel 66 is driven step by step, one step per day and one revolution per moon revolution (29 days, 12 hours and 45 minutes) and that the moon wheel 68 is not driven at not at half the angular velocity as that of the box wheel 66.
- the moon wheel 68 defines a disk 69 having two pellets 70 diametrically opposed having the color, blue, of the sky, the rest of the disc 69 having the yellow color of the moon ( Figure 9B).
- the counter wheel 66 located above of the moon wheel 68, defines a disc 71 having the blue color of the sky and having a circular aperture 72 of the same diameter as the pellets 70 (FIG. 9C).
- the full moon appears through the window 72 when this last is at the position at six o'clock and is between the two pellets 70.
- the new the moon appears, it, when the wicket 72 and one of the two pellets 70 are at noon. From this position at noon, the user will see the moon grow day by day in the right part of the wheels 66, 68 until the full moon and then decrease in the part left of the wheels 66, 68.
- This device for displaying the moon phase is known. in itself. It was described by Mr. Philip Barat in his thesis work thesis of the Engineering School of Geneva in June 1983.
- the perpetual calendar mechanism furthermore comprises correctors 73, 74, 75, 76 for manually correcting the position angular, respectively, of the date mobile 16, 28-31, of the star of days 17, the moon gear 62 and the pinion of the months 47.
- These correctors 73-76 are actuated by pushbuttons (not shown) projecting from the slice of the watch.
- Each of the correctors 73-75 is a simple pivoting member arranged to push a tooth of the date wheel 28, the star of days 17 and moon gear 62, respectively.
- the corrector 76 associated with the pinion month 47 includes (see Figure 5) two pivoting parts 78, 79 of axes of different pivoting.
- the piece 78 carries a pin 80 cooperating with a buttonhole 81 of the piece 79 and further comprises a finger 82 capable of lifting the correction flip-flop 4 when in contact with the cam of months 26 or leap year cam 27 and a spout 83 adapted to push a tooth of the sprocket month 47 after the 82 finger raised the correction rocker 4 to move the pinion of the months 47 of a step in the clockwise direction of hours and minutes of the watch.
- the perpetual calendar mechanism according to the invention operates from the following way.
- the calendar rocker 3 In the rest position, the calendar rocker 3 is maintained by its spring 12 against a stop 84 (visible in FIG. 2) and the rocker of correction 4 is held by the return spring 13 acting on the shuttle 11 in a position where the probing pin 25 bears against the periphery of the cam of months 26 or the leap year cam 27.
- the probing pin 25 is in contact with a part high 55 or an intermediate portion 56 of the periphery of the cam of the months 26 when you are in a month of 31 days or 30 days respectively, with the part of the periphery of the leap year cam 27 other than the bump 58 in the indentation corresponding to the lower part 57 of the cam of the months 26 when one is in a 28-day month, or with the cam's hump 58 leap year 27 when in a month of 29 days.
- the angular position of the correction lever 4 in this rest position is different depending on the part of the periphery of the cam of months 26 or cam leap year 27 that touches the feeler pin 25, that is to say according to the month where we are.
- the date finger 2 comes into contact with the finger 10 of the correction rocker 4 and begins to lift gradually this rocker 4 against the action of the return spring 13, which distances the probing pin 25 of the 26-month cam and the leap year cam 27.
- the time at which the date finger 2 comes into contact with the finger depends on the aforementioned angular position of the correction lever 4 in its rest position and thus the number of days in the current month. Plus the month in course has a large number of days, this time will be late and therefore less the amplitude of displacement of the correction lever 4 under the action of the finger of date 2 will be great.
- the rake 22 When raising the correction lever 4, the rake 22 causes shuttle 11 rotating which slides the free end of the large pawl 40 on the peripheral surface of the correction cam 31. During the days other than the last day of a month under 31 days, this free end slip of the large pawl 40 has no effect on the angular position of the mobile of date 16, 28-31. However, on the last day of a month of 30 days, 29 days or 28 days, the free end of the large pawl 40 comes into contact with the recess, designated in FIG.
- each displacement of a step of the mobile of date 16, 28-31 by the big pawl 40 breaks down in a first movement, slow, during which the large pawl 40 pushes the correction cam 31 against the action exerted by the jumper 20 until the top of a tooth of the date star 16 in contact with the jumper 20 reaches the tip, designated by 86, of the latter and a second movement, rapid, caused by the fall of jumper 20 on the other side of said tooth and from which the large ratchet 40 loses momentarily the contact with the recess 85.
- the second small ratchet 15 catches a tooth of the star of days 17 to angularly and instantly move this star 17 and thus the needle Indicator of the days of the week 18 of a step for the indication of the following day.
- This instantaneous displacement of one step of the date mobile 16, 28-31 and of the star of days 17 by the little pawns 14, 15 occurs every day, that whether or not at the end of a month of less than 31 days. If the current day is the last day of a month under 31 days, this instant move a step of the mobile of date 16, 28-31 will succeed the moving movement of this mobile by the big ratchet 40 to complete the passage of the last day of the month in course on the first day of the following month.
- the wheel units 29 of the date mobile 16, 28-31 moves the pinion of the units 32 one step in order to move the date unit displayed in the aperture 38 to the next unit, except once a month, when the date mobile 16, 28-31 is in an angular position corresponding to the calendar 31.
- the toothing of the gear of the units 32 is opposite the empty space 29 'of the toothing of the wheel of the units 29 and is therefore not driven .
- the pinion of the tens 34 is driven by the wheel of tens 30 of the mobile calendar 16, 28-31 only four times a month, corresponding to changes of tens of the date, when the teeth of the tens gear 34 is in the path of one of the four teeth of the tens wheel 30.
- the disk of the tens 35 secured to the pinion 34 also moves to display the tens the next date in box 39.
- Each rotation of a step of the date wheel 16, 28-31 also causes, via the intermediate date wheel 41 and the idler gear 42, a rotation of one wheel step of the month 43 and the disk of the months. 44.
- This rotation of a pitch of the wheel 43 and the disk 44 does however cause a rotation of the pinion of the months 47 by the finger 45 of the month disk 44 that when the mobile date 16, 28-31 passes from an angular position corresponding to the 31 at an angular position corresponding to the 1st , the finger 45 being the rest of the time outside the teeth of the pinion of the months 47.
- Each rotation of a step of the pinion of the months 47 rotates a step the cam of the months 26 and the indicator hand of the month 48 located above the display area of the months 49 on the dial of the watch for the passage to the following month.
- Each rotation of a step of the pinion of the months 47 also causes a rotation of one step of the wheel of 48 months 50 which drives itself, through the wheels of the year 51, 52, a rotation of a not the leap year cam 27 and the leap year indication needle 53 associated with the display area 54 on the watch face.
- the fingers 9, 10 of the latches 3, 4 are shaped so that the fall of the date scale 3 always intervenes before the fall of the correction 4.
- the instantaneous displacement of a step that the mobile calendar 16, 28-31 during the fall of the calendar rocker 3, displacement which, as explained above, causes a displacement of the pinion months 47 and the cam of the months 27 at each end of the month occurs while the probe 24-25 of the correction lever 4 is removed from the surface cam device 26, 27. In this way a blockage of the mechanism.
- the position angle of the date mobile 16, 28-31, the star of the days 17, the pinion of moon 62 and pinion 47 months can be corrected manually by intermediaries 73-76 respectively, and this without risk of blocking.
- Concerning more particularly the pinion of the months 47 it should be noted that a rotation of this pinion 47 by the corrector 76 never affects the position angle of the date mobile 16, 28-31. Indeed, when this rotation takes place while the finger 45 is out of the teeth of the pinion of the months 47, the disc of month 44 can not be driven by the pinion of the months 47.
- the present invention shows several benefits in addition to those already mentioned.
- One of them is that the indication of date change is made instantaneously most of the time, namely when changing from one day to the next within a month and during from the last day of a 31-day month to the first day of the following month, but with a reduced risk of seeing the mobile of date 16, 28-31 driven by its inertia in an undesired displacement, thanks to the fact that the moving the date wheel 16, 28-31 during the passage of the last day one month less than 31 days to the first day of the following month is made in part in a slow way.
- the instantaneous movements of the date mobile 16, 28-31 are always limited to one step.
- Another advantage of the invention is that it allows, by the presence of two latches 3, 4 respectively carrying the small pawl 14 and the large pawl 40, to create a sufficient displacement angle for the ratchets 14, 40 while freeing up space for another display device namely, in the example illustrated, the device for displaying the moon phase 62-68, and while allowing a large format display of the date by two juxtaposed disks 33, 35.
- the mechanism according to the invention allows a user-friendly layout of different clearly readable display areas on the dial of the watch.
