Definitions

  • the present invention relates to a mechanism for annual calendar for watch movement including a mobile date indicator at thirty-one positions in taken once a day with a training mobile in kinematic link with the train of said clockwork movement, an annual cam whose contour is shaped to distinguish the 31-day months from other months, means to train this cam at the rate of one turn per year and one correction mechanism connected to said annual cam for advancing said mobile indicator by an additional position at the end of each month less than 31 days.
  • the purpose of the present invention is to make an annual simple date mechanism, preferably instantaneous, with using a solution adding as few extra pieces as possible, ensuring safe operation and small footprint.
  • the subject of the present invention is a date mechanism of the aforementioned type, as defined by claim 1.
  • this mechanism lies in its simplicity and in its efficiency and reliability. advantageously, this mechanism can be associated with a date at instant jump and allows automatic correction at the end months of less than 31 days also instantly.
  • the date mechanism illustrated in Figures 1 to 5 comprises an annular mobile 1 carrying the date of 1 to 31.
  • This annular mobile 1, more generally called disc of the dates has a usual internal toothing 1b and is integral with an annular correction cam 1a.
  • Tooth 1b is engaged on the one hand with a jumper positioning 2 ( Figure 6) and secondly with a finger drive 3 secured to an instantaneous jump cam 4 concentric with a drive wheel 5.
  • An opening in circular arc 5a integral with the drive wheel 5 and a pin 4a secured to the instantaneous jump cam 4 are used to make this cam integral with the drive wheel, but with a certain angular play whose role will be explained later.
  • a roller 6a of a rocker 6 for the instantaneous change of dates, is pressed against the around the instantaneous jump cam 4 by a spring 7.
  • a second finger 3a is intended to train a star on weekdays 17 through seven arms, once a day at the same time as the disc of 1.
  • the invention is not however limited to the presence of this 17 day star, the mechanism according to the invention can only include the indication of dates.
  • the mechanism which has just been described is that of a simple instantaneous calendar.
  • the date disc is integral with an annular correction cam 1a against which a correction lever 8 provided with a roller 8a is applied by a spring 9.
  • This correction cam 1a has a long circular ramp 1a ' intended to arm the spring 9 of the correction lever.
  • This annular ramp 1a extends over an angle of approximately 348 ° (30/31 th ), gradually moving away from the center of rotation of the date disc and ends with a concave curve 1a * connecting the end at the beginning of the long circular ramp which extends over approximately 12 °.
  • This concave curve 1a * allows the rocker 8 pressed by the spring 9 to advance the disc by the date by one step thanks to the energy stored by the spring 9. Note that the shape of the concave curve 1a * connecting the two ends of the circular ramp 1a 'is not essential for the operation of the automatic correction mechanism and could be replaced by a simple straight ramp.
  • the internal edge of the correction cam 1a carries a tooth, a finger, or a projection 10, intended to come into engagement with each rotation of the date disc 1 with a correction star 11 in taken with a positioning jumper 12 pressed by a spring 13.
  • This correction star 11 is integral with a reference 14 meshing with a reference 15, itself engaged with a mobile month indicator 16, concentric with the star of days 17.
  • a circular annual cam 18 is concentric to reference 15. It includes an ankle 18a engaged with an opening in an arc 15a of the reference 15.
  • a spring 19 one end of which is integral with the reference 15 and whose the other is integral with the circular annual cam 18 tends to hold the ankle 18a against the left end of opening 15a.
  • the circular annual cam 18 is divided angularly in twelve equal sectors, each corresponding sector to a month of the year.
  • the 31-day months correspond to the large diameter parts 18 ′ of the cam 18, whereas the five months of less than 30 days correspond to small diameter parts 18 * thus forming five hollows in the large diameter portion 18 'of the annual cam 18.
  • the correction lever 8 has a finger 8b which is intended to cooperate with the annual cam 18 at the end of each month as will be explained now.
  • the roller 8a of the correction lever 8 arrives towards the end of the circular ramp 1a 'of the cam 1a.
  • the finger 8b of the correction scale 8 is located opposite a large diameter portion 18 ′ of the annual cam 18. Going from 30 to 31 (FIG. 2), it can be noted that the roller 8a of the scale of correction 8 has exceeded the end of the circular ramp 1a 'of the correction cam 1a, but the large diameter portion 18' of the annual cam 18 which is opposite the finger 8b prevents the rocker 8 from descending along the concave curve 1a * of the correction cam 1a. Therefore, the transition from August 31 to September 1, is normally carried out with the drive finger 3 secured to the cam instantaneous jump 4, as seen in Figure 3.
  • the roller 8a of the correction cam 8 has passed from the end to the start of the circular ramp 1a ′ of the correction cam 1a.
  • the finger 10 of this correction cam 1a drives the correction star 11 by one step. Since the reference 14 is integral with the correction star 11, the reference 15 and the month indicator mobile 16 are driven simultaneously with the correction star 11. This rotation allows the finger 8b of the correction lever 8 to penetrate between two large diameter parts 18 ′ of the correction cam 18, corresponding to a month of less than 31 days, here the month of September. As with each change of date, finger 3a rotates the day star 17.
  • Figures 4 and 5 show the transition from 30 September to 1 October.
  • the correction lever 8 and the correction cam occupy the same position as in FIG. 1, but the annual cam 18 is arranged so that a recess situated between two large diameter parts 18 ′ is located -with finger 8b of the correction rocker. Consequently, during the next training of the date disc 1, on September 30 at midnight, finger 3 normally moves the date disc by one step, thus bringing the roller 8a of the correction lever in the position illustrated in the figure.
  • the correction star 11 is moved one step at the same time as the references 14 and 15 and the mobile for months 16. Since the finger 8b of the correction lever 8 is engaged in a hollow of the annual cam 18, this cannot rotate. It's here reason why the annual cam 18 remains stationary and the opening in a circular arc 15a formed in the reference 15 allows relative angular displacement between this reference 15 and the annual cam 18. During the following month, the scale correction 8 is gradually raised by the ramp circular 1a 'of the correction cam 1a.
  • the finger 8b of the rocker 8 falls into a recess 18 * of the annual cam 18.
  • the friction between the finger 8b of the lever 8 and the part 18 'of the annual cam can be greater than the torque developed by the spring 19, so that instead of falling straight away in the hollow 18 * of the annual cam 18, the finger 8b will remain on the large diameter portion 18 'of the cam 18 while the reference 15 is driven by the finger 10, the star 11 and the reference 14, thus arming the spring 19.
  • the annual cam 18 will be angularly moved one step clockwise by the trigger spring 19, so that the finger 8b of the rocker 8 will then fall into a hollow 18 * d e the annual cam 18, corresponding to a month of less than 31 days.
  • the opening 5a formed in the drive wheel 5 of the date, in which the pin 4a of the instantaneous jump cam 4 is engaged allows movement relative angularity of a step between this cam 4 and the drive wheel 5, in kinematic connection with the train indicator of the timepiece, to allow the instantaneous jump to the date disc 1.
  • the drive finger 3 secured of the instantaneous jump cam 4 is between two teeth of the teeth 1b and since the pin 4a of the cam 4 moved during the jump to the other end of the opening in an arc 5a of the drive wheel 5, it guarantees that the date disc 1 cannot jump more than one step, the training finger 3 then playing the role of locking device.
  • the annual calendar mechanism in this version will be instantaneous, but the passage from 30 to 1 st , in the case of a month of 30 days, will be done in two stages, the 31 being displayed for a certain time, until that the drive wheel advances and brings out the finger 3 of the teeth 1b of the date disc 1.
  • FIG. 6 illustrates a variant which makes it possible to avoid this transition from 30 to 1 st in two stages.
  • the date disc 1 is pivotally mounted on three guide rollers 20a, 20b, 20c pivotally mounted on the plate P carrying the calendar mechanism, on either side of the end of the positioning jumper 2 of the disc of dates 1 which is in contact with the teeth 1b of this disc 1, so that this jumper 2 pressed by a spring 2a formed by an elastic arm come in one piece with it, applies this date disc 1 against these rollers guide 20 by guiding it around a virtual axis coinciding with the center of this date disc 1.
  • a fourth roller 20d located at a certain distance from the edge of the date disc 1 serves as a stop to limit the tilting of the date disc 1. This tilting allows the teeth 1b of the date disc 1 to move away from the finger 3 after the jump from 30 to 31 during the transition from 30 to 1 st , so that this jump of two steps of the date disc then becomes instantaneous while maintaining the locking intended to prevent the jump of two dates in the other cases.
  • the spring 9 pressing the rocker against the correction cams 1a and annual 18 is a spring with two arms, one of which presses correction flip-flop 8, while the other presses a zipper 21 for setting the time and setting the date of winding and time setting mechanism.
  • this zipper 21 is in the position illustrated in lines mixed in Figure 5, position in which the rod winder 22 occupies an axial position pushed towards the center of the watch movement. When we pull this pull outwards to bring it into the drawn position in solid lines in FIG.
  • the annual calendar mechanism according to the present invention is extremely simple, since it does not include that a correction cam 1a, a correction rocker 8, an annual cam 18 which neutralizes or not the action of the correction cam 1a and a drive star 11 of this annual cam 18.
  • This simplicity guarantees the reliability of the mechanism, all the organs being made up by toothed organs with the exception of the correction scale 8 necessary to take the additional step to the end of the months of less than 31 days and which makes it possible to return this instant fix.
  • This mechanism occupies little space as well in plan that in height.
  • this invention is obviously applicable to other date mechanisms semi-instantaneous jump or trailing change of date.
  • this invention also applies to a calendar indicating the date, the day and month, like a single calendar or a calendar indicating the date and the day.
