Definitions

  • the present invention relates to an annual calendar mechanism for a timepiece comprising a date-driven mobile moving around in twenty-four hours, this mobile being equipped with a first finger causing a step and once a day. a first stage of a date ring having thirty-one inner teeth, said mobile being equipped with a second finger causing a step and at the end of a month of less than thirty-one days one of the five pins which is provided with a board integral with an annual wheel arranged coaxially with the date ring, said mechanism further comprising a reference connecting at the end of each month, said annual wheel to a second stage of said date ring.
  • EP-A-1 251 412 uses a two-stage ring supporting the display of the date and an annual wheel arranged coaxially with said ring.
  • a first finger of the mobile trainer is engaged with the thirty-one inner teeth of a first stage of the ring, a second finger being located at the end of a month of less than thirty-one days on the road.
  • a five-pin board on which is fixed an annual wheel with seventeen teeth.
  • This annual wheel is engaged with a referral also comprising seventeen teeth, seven of which are thinned.
  • the second stage of the ring carries two inner teeth, one of these teeth being thinner than the other.
  • the names of the thirty-one-day months (January, March, May, July, August, October, December) appear once and the names of the months of less than thirty-one days (February, April, June, September, November) figure twice through a window cut in the dial of the timepiece.
  • the document CH-B-684815 implements more particularly an annual calendar where the date display is a needle.
  • the annual wheel is not central, but offset on the top of the timepiece. This leads to a complicated mechanism, the names of the months appearing on an off-center disc grappling with a reference with thirty-one teeth, thirty of which are truncated.
  • the present invention in addition to fulfilling the generic definition expressed in the first paragraph of this description, is remarkable in that the annual wheel has twice as many teeth as the year comprises month and the return includes a first wheel engaged with the annual wheel and a second wheel fixed integrally on and disposed coxialement to the first, the second wheel being engaged at the end of each month, with a lug arranged to inside the second floor of the date ring.
  • This mechanism comprises, in a known manner, a mobile 1 day trainer making a turn in twenty-four hours.
  • This mobile 1 draws the driving force acting on it of a kinematic chain driven by the movement of the timepiece whose last link is illustrated by the wheel 15.
  • the mobile 1 is equipped with a first finger 2 which leads d a step and once a day at midnight a first stage 3 of a date ring 4 carrying thirty-one inner teeth, three of which bear the references 10, 11, 12.
  • the mobile 1 is still equipped with a second finger which leads one step and at the end of each month with less than thirty-one days a board 6 by one of its five pins 20 to 24 (see Figure 3).
  • the board 6 is integral with an annual wheel 7, the assembly 6, 7 being disposed coaxially to the ring 4.
  • the figures finally show that the annual calendar mechanism further comprises a reference 8 which connects, at the end of each month, the annual wheel 7 to a second stage 9 of the date ring 4.
  • the mechanism of the present invention is distinguished by two remarkable and original arrangements. It is first of all the annual wheel 7 which has twice as many teeth 30 as the year comprises of months. In other words, the annual wheel 7 comprises twenty-four teeth 30. It is finally the reference 8 which comprises a first wheel 40 in engagement with the annual wheel 7, the teeth 30 of the latter meshing with the teeth 41 of the first wheel 40. The reference 8 further comprises a second wheel 50 fixed on and arranged coaxially with the first wheel 40. This second wheel 50 is engaged at the end of each month, with a lug 60 arranged inside. of the second stage 9 of the date ring 4. The figures show that the lug 60 is driven by the teeth 51 which comprises the second wheel 50.
  • the two wheels 40 and 50 which form the reference 8 are provided with teeth 41, respectively 51, regularly distributed around the periphery of the corresponding wheels, which leads to a very conventional machining, this in contrast to the machining employed. for the return of EP-A-1 251 412 cited above.
  • the same remark can be made about the lug 60 disposed inside the second floor 9 of the date ring 4, this lug being unique in contrast to the two lugs located on two different levels and necessary for the operation of the equipping calendar. the document cited.
  • FIGS. 1 to 8 also show that the date ring 4 carries a date indicator ring 25 on which are affixed thirty-one numbers 26. These figures appear in turn through a window 27 cut in a dial 28 who wears the timepiece.
  • the annual wheel 7 carries a disc indicator of months 16 on which are affixed the names of the twelve months of the year 17. These names appear each month twice and in turn through a wicket 18 cut into the dial 28. We see that the indicator disc of the month thus comprises twenty-four equal sectors.
  • Figures 1 to 3 illustrate the transition from one month to another for months of less than thirty-one days.
  • the passage from April 30 to May 1 is taken as an example.
  • FIG. 1 shows the situation of the display on April 30 at 11:30 pm.
  • the first finger 2 of the date-driven mobile phone 1 comes into contact with the inner tooth 10 of the first stage 3 of the date ring 4.
  • the date indicator ring 25 shows a number 26 through the window 27 which is the 30 (April).
  • the indicator disc of the months 16 shows the name of the month of April for the first time 17 through the window 18.
  • the lug 60 disposed inside the second floor 9 of the date ring 4 is close to the tooth 52 of the wheel 50 which forms the reference 8.
  • Figure 3 shows the position of the display 1 May to 2 hours 00.
  • the moving body 1 by his second finger 5 has resulted in the plate 6 and its lug 20 in a counterclockwise direction.
  • the annual wheel 7, secured to the board 6, led it was becomes leading and in turn causes the reference 8 clockwise and its tooth 53 advances the date ring by its tooth 60.
  • the indicator ring 25 has the number 1 through the window 27.
  • the annual wheel 7 has driven the indicator disc months 16 which then displays a first time May 32.
  • the five pins 20, 21, 22, 23 and 24 each correspond to months of less than thirty-one days, namely the months of April, June, September, November and February. It is arranged that each of these lugs is on the path of the finger 5 of the mobile 1 at the end of the months just mentioned.
  • the lugs 20 to 24 are necessarily placed around the board 6 at 60 °, 90 °, 60 °, 90 ° and 60 °.
  • the mobile trainer of the date 1 may be of the semi-instantaneous transit type in which case a jumper (not shown) must be placed on the internal toothing of the date ring.
  • Figures 4 to 6 illustrate the transition from one month to the next for the months of thirty-one days. The transition from May 30 to June 1 is taken as an example.
  • FIG. 4 shows the situation of the display on May 30 at 11:30 pm.
  • the finger 2 of the driving mobile 1 comes into contact with the inner tooth 10 of the date ring 4.

  • the indicator disc of the months 16 shows the name of the month of May for the first time 17 through the window 18.
  • the lug 60 of the date ring 4 is close to the tooth 52 of the wheel 50 which forms the reference 8. If one observes the angular position of the lug 20 of the board 6, it is found that the annual wheel has remained at the position it had on May 1 to 2:00 (see Figure 3).
  • Figure 5 shows the situation of the display on May 31 at 23:30.
  • the date ring 4 and its tooth 10 have progressed by one step.
  • the date indicator ring 25 has the number 31 through the window 27 and, at 23:30 on May 31, the finger 2 of the mobile 1 comes into contact with the inner tooth 11 of the date ring 4.
  • the lug 60 linked to the date ring has also progressed by one step driving the wheel 50 by its tooth 52 in the clockwise direction.
  • the wheel 40 secured to the wheel 50 to form the return 8 in turn causes the annual wheel 7 in the counterclockwise direction and therefore in the same direction the board 6 and the lug 20 which is related thereto.
  • the annual wheel 7 has progressed one twenty-fourth of a turn as well as the indicator disk of the months 16 which is linked to it.
  • the name of the month of May appears a second time 32, but shortly, through the window 18.

The 1 1 June 25 of the calendar indicator appears through aperture 27. The lug 60 also advanced a step involving the dismissal 8 clockwise. By turning, the third wheel 70 by its tooth 72 advances the star 80 by its tooth 82. The disc of the 90 months linked to the star 80 also advances one step and the month of June 93 appears through the counter 100.
  • the second embodiment of the invention which has just been described makes it possible to propose an easier reading of the name of the months.
  • the disc of the 90 months has only twelve sectors, one sector per month which allows to significantly increase the name of the month and increase its readability.
  • Figures 9 to 14 show this advantage and especially a harmonized graphic between the date and the month which has a very similar size. It will be understood that this can not be achieved if the months disk (FIGS. 1 to 6) has twenty-four sectors in which case the name of the months must be decreased next to the numbers displaying the date.
  • the annual calendar mechanism according to the invention is very simple to manufacture since it comprises only conventional wheels cut regularly, the teeth they wear being uniformly distributed around their periphery. It will be noted that the mechanism in question can very easily replace a simple date mechanism with only the date and without significant modification of the basic caliber. This is notably the case of the 2892 A2 caliber put on the market by ETA SA Manufacture Horlogère Suisse.
