Definitions

  • the present invention relates to timepieces with display of calendar. It relates, more particularly, to a mechanism indicating the date and day of the week intended to equip a movement of shows.
  • the purpose of the present invention is precisely to meet this wish.
  • the invention relates to a mechanism indicating the date and day, intended to equip a timepiece movement, characterized in that it comprises, arranged side by side, a ladder date indicator and a day indicator scale displaying, each day, respectively a series of several calendars and a series of several days, and means to have at least one of these displacement scales allowing to establish between them, at least partially, a good date-day correspondence.
  • the two indicator scales respectively display seven dates and the seven days of the week.
  • the mechanism according to the invention further comprises, a corrective date scale carrying a series of several and arranged so that they can partially overlap with the date indicator scale, and means for causing this correction scale of displacements which allow it to hide, at the end months of less than 31 days, inaccurate dates and replace them with his.
  • the mechanism further comprises a needle intended to show the date of the day and the control means are arranged to make this needle, every evening around midnight, an advance of one day.
  • the means used to move the different scales can be either purely mechanical or electromechanical.
  • the timepiece shown schematically in Figures 1 and 2 is intended to display, on a dial 10, the hour, minute and second of the current time, but also the calendar and the month.
  • the hour and minute are displayed in the center of the room respectively by large hands 11 and 12, while the second is displayed, at position 6 hours, by a small hand 13.
  • the month is displayed using a disc appearing behind a window 14 at the 3 o'clock position.
  • this timepiece lies in the mechanism allowing to display each day, in window 15, with the help of the needle 16, the correct date opposite the correct day of the week, than the current month either 31, 30, 29 or 28 days.
  • Figure 2 shows, for example, the state of the play on February 29 of a leap year.
  • FIGS 3 to 7 represent schematically, according to different configurations, the constituent organs of the mechanism fitted to the part in Figures 1 and 2. It forms a module arranged on a classic movement and coupled to it according to any technique well known to those skilled in the art.
  • the figures show a date indicator 17 constituted, so known, by a disc crown whose upper face carries the thirty-one dates visible in series of seven through the window 16 opposite from the seven day of the week series.
  • the inner part of the crown 17 has thirty-one teeth used, on the one hand, for its training by means which will be described and, on the other hand, to its positioning by a classic long necklace not shown.
  • the mechanism includes a twenty-four hour wheel 18 driven in the counterclockwise (below, SIAM), one turn per day, from the hour wheel of the movement.
  • the wheel 18 carries, on the top, a stud 19 meshing with a star of thirty-one 20 arranged at the center of the movement and whose pinion 21 carries the indicator needle for date 16.
  • the star 20 carries, on its underside, a stud 22 whose role will appear later.
  • the pinion 21 meshes with a first rack 23 forming the end an arm 24 which pivots about an axis 25.
  • the arm pivots in the SIAM, it loads a spring 26.
  • the other end of this arm is provided with a second rack 27 which meshes with a ratchet clutch mobile 28, of a type well known to those skilled in the art, cooperating with the teeth internal of the date indicator 17.
  • the rack 27 has no effect on this mobile when it pivots in the SIAM but, when it pivots in the direction clockwise (below, SAM), it trains it to do advance indicator 17 in the SIAM.
  • a pawl 29, acting under the effect of a spring 30, serves to prevent, by a from its ends, that the star of thirty-one 20 turns in the SIAM.
  • the other end of this ratchet has a notch in which takes place a pad 31.
  • the latter is fixed to one end of a pivoting lever 32, the other end of which is arranged so as to be on the trajectory of the stud 22 equipping the star of thirty-one 20.
  • the lever 32 is subjected to the action of a spring 33 which tends to bring its free end towards the center of movement.
  • the mechanism In operation, the mechanism is located on the night of Sunday at Monday, after the midnight jump, in the position illustrated in Figure 3 for the week from Monday 7 to Sunday 13. Needle 16 is then pointed towards Monday calendar. Each of the following evenings, around midnight, the stud 19 will then advance the star of thirty-one 20 by one position, with its stud 22 and its needle 16 which, thus, on Sunday evening, will be pointed towards the 13, as shown in Figure 4.
  • the mechanism would be perfect if every month had 31 days. As it is not the case, the indication of the date designated by hand 16 will not be correct for months less than 31 days. So, for example, for a month of 30 days ending on a Thursday, the calendar at the Friday position will be 31, when it should be 1.
  • the mechanism according to the present invention provides a solution to the problem by making it possible to establish a perfect match, at the end of the months less of 31 days, between the indication of the day and that of the date.
  • the mechanism uses a corrector 34 in the form of a sector disc crown 34 centered on the movement, with the same radius as the indicator 17. It carries, on its left side, the series of dates from 1 to 6 and is dimensioned so as to overlap exactly on indicator 17 to hide inaccurate dates and replace them with his.
  • the sector 34 is endowed with inward teeth for its training.
  • the corrector 34 is, in its state initial, illustrated by figures 3 and 4, shifted by 3 positions compared to the last date appearing in the window 15.
  • a first manual initialization performed before the Sunday evening preceding the end of a month under 31 days, brings the corrector 34 closer to the last of the dates visible in window 15.
  • This initialization is 1 position for the months of 30 days, 2 positions for the months of 29 days and 3 positions for the 28 day month.
  • the date 1 of the corrector is brought at 2, 1 and 0 positions respectively at the end of the 30, 29 and 28 day months.
  • a second initialization must be carried out, advantageously at the same time time than the first, in order to advance the date indicator 17 by 1, 2 or 3 positions respectively for the months of 30, 29 days and 28 days.
  • Figures 3 and 4 show the mechanism before the two initializations. These being carried out, the mechanism according to the invention must therefore, at the start in the last week of months of less than 31 days, i.e. changeover time from Sunday to Monday, allow moving automatically the correction sector 34 of a number of positions which depends on the Monday date between 23 and 30. This number is 1, 2, 3, 4, 5, 6, 7 and 8 depending on whether the last Monday is respectively 23, 24, 25, 26, 27, 28, 29 and 30. The mechanism must also, of course, bring back the corrector 34 to its initial state the following Sunday evening.
  • the mechanism has, as a point the internal teeth of the date indicator 17 which, by by means of two mobiles 35 and 36, meshes with an associated wheel 37, above her, at a star of thirty-one 38.
  • the rest of the circumference of the star is smooth.
  • the eight-tooth sector 39 meshes with a pinion 40 whose circumference is equal to the length of the arc of sector 39, which is positioned so as to attack the pinion at the start of the 23rd of the month.
  • This sprocket is associated with an eight-tooth wheel 41 held in place by a jumper 42 and meshing with a corrective wheel 43 which has the particularity of have a sector of nine notches 44 with spacing corresponding to that of the teeth of the wheel 41.
  • Three of these notches, bearing the references n1, n2 and n3 correspond to the corrections to be made at the end months of 30, 29 and 28 days, while the other six, bearing the references n4 to n9, are used to correct the days.
  • the rest of the circumference of the wheel corrective 43 is tooth free.
  • the wheel 43 is associated, below it, with a wheel 45 meshing, by by means of two mobiles 46 and 47, with the internal toothing of the sector correction 34.
  • the wheel 45 meshes with a rack 48 forming the end of an arm which pivots around an axis 49.
  • a spring 50 When the pivoting takes place in the SAM, it loads a spring 50.
  • a seven-day star 51 is driven, one revolution per week, by a finger 19 'carried, like the stud 19, by the twenty-four hour wheel 18.
  • This star has a tooth 52 which acts on a ratchet 53 allowing rotation of wheel 45, in SIAM, under the action of spring 50, every Sunday around midnight.
  • a barrel 54 is engaged with the internal toothing of the date indicator 17 on which it acts only when it turns in the SIAM. It is associated with a retaining pawl 55, subjected to the thrust of a spring 56 and actuated by a tooth 57 formed inside the right part of the corrector 34.
  • the eight-tooth sector 39 attacks the pinion 40, the eight-tooth wheel 41 which is associated with it turns in a vacuum because the corrective wheel 43 does not present it its sector with nine notches 44.
  • the corrector 34 will therefore remain stationary during the transition from 31 to 1 st .
  • the corrective wheel 43 advanced by one position in the SIAM. Sunday evening, at the time of the jump of 7 positions of indicator 17, the notch n2 of the wheel 43 and the following ones can thus mesh with the eight-toothed wheel 41. Everything will then be determined by the date of the following Monday.
  • the corrective wheel 43 will advance by 1, 2, respectively 3, 4, 5, 6, 7 or 8 positions, thus advancing the corrector 34 by the same number of positions to hide erroneous dates displayed by indicator 17 and replace them with a correct date indication.
  • a date indicator mechanism displaying together, from Monday to Sunday, the dates of the 7 days of the week opposite the corresponding day, whether the month is 31, 30, 29 or 28 days.
  • the mechanism could, as illustrated by figure 8, while keeping the principle of a 7-day day-date display, have a day indicator and a calendar advancing daily from one position, both visible behind the window 15, the right day-date pair always being that at the bottom of the scale without the need to show it with a needle.
  • the posting could also be done over two weeks or, more generally, n days.
  • the corrector should include the dates from 1 to n-1.
  • the date indicator 17 is surrounded by a crown disc 58 whose upper face carries four series of indications of the seven days of the week, both visible through window 15.
  • the corrector 34 then takes the form of a disk sector centered on the movement.
  • These three bodies are respectively driven in rotation by three step motors step 59, 60 and 61 which are controlled by a microprocessor (not shown) appropriately programmed by those skilled in the art to, on the one hand, to advance the indicator each evening by one position date 17 and the day indicator 58 and, on the other hand, to position the corrector 34 so that at the end of the months of less than 31 days, it conceals the inaccurate dates and replaces them with his own.
