Definitions

  • the present invention relates to a timepiece comprising an indicator dial, a date mechanism comprising a date mobile and a step-by-step driving member of this mobile, a mobile of the months, disposed below said indicator dial. and connected to the mobile date of the month by means of stepping drive shaped so that the moving months turn at an angle of 30 ° each month.
  • a date and month indicator device of this type is disclosed in the document EP 1158374 .
  • the integration of a complementary mechanism for displaying the indication of the months usually requires the establishment of one or more additional indexing jumpers.
  • the energy accumulator of the date mechanism must deliver an additional amount of energy to be able to overcome the sum of the couples produced by the multiple jumpers.
  • the resulting loss of energy at the sprung balance may cause a decrease in its amplitude and affect the accuracy of the watch.
  • the solution to reduce the jumper springs is not indicated because it may cause jumping jumps or accidental double jumps.
  • the CH 695 227 describes a mechanism of perpetual instantaneous jump calendars whose mobile date has two large disks of superimposed dates.
  • the first disc the dates of the first fifteen days of the month and the second disc those from 16 to 31.
  • a window is provided in the first disc between 15 and 1 of the month so that the dates of the second disc can be seen from 16
  • the operation of this calendar is dependent on the cooperation and synchronization of these two disks which are each rotated by their internal teeth meshing with a separate drive wheel.
  • the disk drive is programmed via an auxiliary cam, a control lever and wire spring switches, mounted on the first disk and cooperating with the geometry of the second disk.
  • the indication of the months is ensured by a small needle, arranged in the center of the movement, which points towards one of the twelve indexes of the hours also acting as index of the months.
  • the wheel which carries the month hand is devoid of indexing spring, and is directly engaged with the date indicator wheel by means of a gear train and a Maltese cross for locking and closing. 'training.
  • the object of the present invention is to remedy at least in part the aforementioned drawbacks.
  • the invention relates to a timepiece according to claim 1.
  • This month display device can be associated with both a conventional calendar and an annual calendar, as described in the EP 1 596 261 , or a perpetual calendar.
  • the distinctive area of the moving month that appears in one of the twelve windows in the dial has an angular extent greater than that of this window, so that any game of this mobile becomes undetectable.
  • the angular displacement of the mobile months can be performed over several days.
  • a distinctive zone extending over an angular sector of 20 ° to 30 ° the transition from one month to another appears to be instantaneous, although in reality the monthly advance of month is done in several days.
  • the energy required for its displacement can be spread over a longer period. This can be advantageous in the case of an annual or perpetual calendar, because the mechanism must be able to chain two, three, or even four consecutive date jumps.
  • the date wheel and the month wheel rotate in opposite directions. Consequently, the untimely angular displacements of these two mobiles are canceled out and no phase difference between the indications given by these mobiles can be caused, in particular in case of shocks.
  • the figure 1 represents a date mechanism 1 of a timepiece, driven in rotation by an hour wheel 14.
  • This mechanism comprises a date mobile 10 preferably in the form of a ring provided with a first annular toothing 11 with thirty-one teeth. This toothing is in engagement with a step-by-step stepping member 13 of known type, and is indexed angularly by a single jumper 17.
  • the date wheel 10 comprises a second toothing formed by a toothed sector 12, intended to mesh with an intermediate mobile 20 in engagement with a mobile of the month 30 which has the shape of a ring gear 31 internally engaged with the intermediate mobile 20.
  • This mobile of the months carries a distinctive zone 32 on its face underlying an indicator dial 40 ( figure 2 ).
  • This dial has twelve 41 angularly equidistant windows.
  • the distinctive zone 32 is preferably a colored zone of a color having a good contrast with that of the dial and with that of the crown of the months 30, but it can also be a transparent zone which reveals a color of the frame of the watch which presents a good contrast with that of the watch and with that of the crown of the months 30.
  • the maximum extent of the distinctive zone 32 is limited to a sector of angle equal to 30 ° while its minimum angular extent is not less than that of a window 41.
  • the toothed sector 12 meshes with the intermediate mobile 20, it drives the latter from a given angle. Since the mobile of the calendars rotates with an angular step equivalent to a thirty-first of a turn in steps, the angle of the sector geared 12 conditions the number of jumps made monthly by the mobile of the months 30.
  • the report of toothed sector gear 12 and intermediate gear 20 is chosen so that the moving month turns at an angle of 30 ° on at least one step of the mobile date. The number of steps is limited by the angular extent of the window, the larger it is, the smaller the number of permissible steps.
  • FIGS 3a-3a 'to 3e-3e' illustrate the sequences of the mobile of the month 30 for a change of month that takes place in four days, that is to say in four steps of the mobile date of 10.
  • the figure 3a represents a portion of the mobile of the months 30 seen by transparency through the indicator dial 40.
  • the latter displays the date 30 of a month of 31 days through the window 43, for example, January 30.
  • the figure 3a ' shows the meshing of the intermediate mobile 20 with the date mobile 10 on the one hand and with the moving month 30 on the other hand.
  • the toothed sector 12 of the date mobile is an external toothing and the intermediate mobile 20 is constituted by a pinion which meshes directly with the toothed sector 12 on the one hand, and with the internal toothing 31 of the mobile months of on the other hand, the mobile of the dates and the motive of the months turn in opposite directions.
  • the moving month 30 rotates in the direction of clockwise while the date of rotation 10 rotates in the opposite direction.
  • the intermediate mobile 20 is not yet engaged with the calendar mobile 10.
  • the distinctive zone 32 fills the window 41 which corresponds to the indication of the month of January.
  • the Figures 3b, 3b ' show the mechanism on January 31, after a first date jump.
  • the angular displacement of a pitch of the dates mobile 10 has brought the sector into dented 12 with the intermediate mobile 20. This resulted in a slight rotation of the mobile 30 months during which the rear end of the distinctive zone 32 has moved closer to the edge of the window 41 of January.
  • the Figures 3c, 3c ' show the respective positions of the mobiles after the second step which corresponds to the passage from January 31st to February 1st.
  • the intermediate gear 20 is in the middle of the toothed sector 12.
  • this pinion was already engaged with the toothing 31 of the mobile 30 months just before the second step, it is rotated by the intermediate mobile 20 during all the second step of the calendar mobile 10.
  • the greater angular displacement during the second step allows the distinctive zone 32 to instantly leave the previous window 41 and to appear simultaneously in the next window 41 by filling it.
  • the figures 3e, 3e ' illustrate the position of the mechanism after the fourth and last step.
  • the intermediate gear 20 is in a position similar to that which it had before the first step, as shown in FIG. figure 3a ' .
  • An inelastic angular locking member 50 of the month mobile 30 is integral with the intermediate gear 20 and serves to prevent inadvertent rotation of the mobile 30 months when the intermediate gear 20 is not engaged with the toothed sector 12
  • this angular locking member comprises at least one locking surface 51 in engagement with a circular surface 15, concentric and integral with the mobile of the calendars 10.
  • This locking surface is interrupted on an angular portion 16 at least equal to and coincident with that of the toothed sector 12. This interruption makes it possible to deactivate the angular locking member 50 to allow rotation of the locking surface 51 when the toothed sector 12 is in engagement with the intermediate gearwheel 20.
  • the angular locking member 50 which operates according to the principle of a Maltese cross, has the shape of a square, each side of which constitutes a locking surface 51.
  • the figures 5 and 6 show a first variant of the display device months, wherein the distinctive area 32 of the mobile months 30 is formed on a disk 34 which is integral and concentric with a toothed gear 33 with external teeth.
  • the toothed sector 12 of the dates mobile 10 is formed on the inner edge of this mobile 10.
  • the intermediate mobile 20 comprises two coaxial pinions 21 and 22.
  • the pinion 21 meshes with the toothed mobile 33, then that the pinion 22 is periodically engaged with the toothed sector 12 of the date wheel 10.
  • the training of the mobile of the months 30 takes place on two steps of the date mobile 10 as represented in the FIGS. 7a-7a 'to 7c-7c' .
  • the display of the dates on the dial 40 of the figure 7a indicates, for example, December 30.
  • the distinctive zone 32 carried by the disc 34 of the mobile of the months 30 is seen by transparency through the indicator dial 40.
  • the toothed sector 12 of the date mobile is not engaged with the second gear 22.
  • the Figures 7b and 7b ' show the position of the mechanism following the first step of driving the mobile 33.
  • the figure 7b shows that the distinctive zone 32 carried by the disk 34 still appears in the window 41 of the month of December while the date 31 appears in the window 43. Comparing the figures 7a and 7b it is noted that the distinctive zone 32 has moved almost all of its angular extent without however encroaching on the next window corresponding to the month of January.
  • FIGS. 7c and 7c ' show the positions of the mechanism after the second step during which the mobiles of the dates 10 and months 30 are in mesh.
  • the angular locking member 50 shown in FIG. figure 5 works on the same principle as that shown in figure 4 .
