Definitions

  • the present invention relates to a method for form a calendar powered by a watch movement to bring up successively and automatically all the dates from 01.03 of a year to 28 or 29.02 of the year next, as well as a mechanism for implementation of this process.
  • the date mechanisms for timepieces can be classified into two types with regard to the display, those which include a graduation bearing successively the digits of the thirty-one calendar of the longest months, and those which relate to two mobiles. separate display, tens and unit digits.
  • This second type of display is generally used to allow larger figures to be displayed than when there are thirty-one dates on the same display mobile, the height of these being necessarily limited by an angle corresponding to 1/31 th of the length of the circumference on which the dates are arranged.
  • the main drawback of this mechanism is the fact that it allows to have either the two disks of units and dozens side by side, or having them superimposed. In the first case, you need two windows to hide the space formed between the edges of the discs, in the second case, the two digits of the date are at two different levels which is not beautiful and hinders the reading.
  • JP 51-34748 relates to a date mechanism at two display mobiles for the units and the tens which is operated by a system of cams and levers allowing to alternate without correction the months of 30 31 days and months.
  • Such a mechanism presents however a major drawback since two months of 31 days follow each other each year, so that a day in August and day in January.
  • the purpose of the present invention is to provide a solution for making a simple annual calendar and reliable.
  • the present invention has first of all for object a process for forming a date activated by a clockwork movement to successively appear and automatically all the dates of 01.03 of a year on 28 or 29.02 of the following year according to claim 1. It also relates to a date mechanism for the implementation of this method according to claim 2.
  • the main advantage of this process is that by arranging the numbers of the units and those of the tens on two separate display mobiles, it therefore becomes possible to display successively and automatically, so without any correction, all dates from 01.03 to 28 or 29.02 of the following year by not moving selectively the mobile display units and tens that one single step a day.
  • the date mechanism illustrated in Figure 1 has two disks, one disk of units 1 carrying ten digits or a multiple of ten for displaying units, a tens 2 disc with four digits or a multiple of four for displaying tens.
  • the digit "0" from the tens 2 disc can be deleted and replaced by an empty space.
  • the two discs 1 and 2 are concentric and allow the display of the digits of units and tens through a single window 5.
  • the disc of the units 1 is secured to a toothed wheel 3 units which has 10 teeth or a multiple of ten.
  • the tens 2 disc is attached to a tens pinion 4 (figure 2) which has four teeth or a multiple of four.
  • Tens pinion 4 and unit wheel 3 are concentric, the pinion 4 being partially housed in a circular clearance formed in the center of the wheel units 3.
  • the surfaces of the two discs 1, 2 carrying the date digits are coplanar, as we can imagine report on figure 6.
  • the unit wheel 3 is connected to the hour wheel of the cog hour indicator (not shown) which makes two turns in 24 hours by an intermediate wheel which drives a calendar wheel 7 at the rate of one revolution in 24 hours.
  • This calendar wheel 7 carries a date finger 8 which drives the wheel of units 3 one step every 24 hours.
  • a reference 10 carried by a tenon 10a secured to the plate of the timepiece meshes with the pinion of the tens 4.
  • This reference 10 is located on the trajectory of a pin 9 carried by the wheel of the units 3, so that this reference 10 is driven one step at each turn of the wheel 3 units and also drives the tens gable 4 also one step.
  • Tens 4 pinion drive coincides with the passage of the disc of units 1 from "9" to "0".
  • the wheel of 3 units carries an auxiliary mobile consisting of a pinion at the end of month 12, a tooth of which is positioned by a cam 15 secured to the tens pinion 4 instead of a tooth hollowed out 11 of the wheel of the units 3.
  • Each tooth of the pinion of end of month 12 is associated with a pivoting roller 14 in ruby. These rollers 14 are located at the height of the cam 15, so that these rollers 14 roll on the cam 15, thus reducing friction to a minimum between this cam 15 and the end of month pinion 12.
  • Cam 15 has a clearance 15a located between two teeth of the tens pinion 4, corresponding to the passage of the digit "3" to digit “0” on the tens 2 disc.
  • this cam 15 and at its release 15a, the end gear of month is locked angularly with respect to the unit wheel 3 when changing tens digits both that a portion of the cam 15 intersects the path of a roller 14, which is the case when changing tens, except when changing from "31” to "01” which corresponds to the recess 15a of cam 15, so that in this case the pinion end of month 12 can turn one step, the unit wheel 3 remaining stationary. Therefore, the tens disk changes from “3” to "0", while the unit disc remains on the digit "1" which corresponds to the digit of the units of calendar "31” and "01".
  • Two positioning jumpers 16 and 17 cooperate respectively with the wheel of the units 3 and with the pinion of the tens 4.
  • the jumper 16 of the wheel of units 3 thicker, is likely to develop a greater torque than the long necklace 17. This keeps the wheel of the units 3 stationary during the transition from the tens disc from "3" to "0" between the "31” and the "01".
  • Figure 3 shows the date mechanism when the drives of units 1 and tens 2 display "30", that is to say that the pin 9 secured to the wheel 3 units rotating in the direction of the arrow on this wheel 3 has just advanced the reference 10 as well as the gable of the tens 4 of a step in the direction of their respective arrows, to move from the position of the figure 2 to that of FIG. 3.
  • Figure 4 shows the position of the moving parts of the mechanism date when the two discs 1, 2 display "31". Note that in this position, a roller 14a of the pinion at the end of month 12 is in front of clearance 15a of the cam 15. Thus when passing from the position of FIG. 4 to that of FIG. 5, the date finger 8 can then rotate the end of month pinion 12 by one step. This one no longer blocked by cam 15, the unit wheel 3 then remains motionless. Thanks to this end of month gear and cam 15, we can directly pass the date of the "31" to "01".
  • Figures 7-11 show how you can shoot take advantage of this peculiarity of the date mechanism described so far to get an annual calendar based on a new concept according to which the date display changes fully automatically from 01.03 to 28 or 29.02 of the following year, without any of the disks or both disks simultaneously move from more than one step per 24 hours.
  • the basic mechanism described above already allows to perform the passage from "31" to "01” by changing only the disk of tens of steps and holding the disk of 1 stationary units. You just have to find a way to simultaneously move the two discs one step to move from "30" to "01” and we then have a very annual calendar simple, capable of implementing this clever process of date change with all listed benefits previously.
  • This date mechanism is identical to the previous one, the only difference is that it has an additional annual wheel 18, allowing to form the annual kinematic chain and that the date finger 8 carries a lug 8a intended to selectively drive the annual wheel as we will explain it later.
  • the annual wheel 18 has twenty-four teeth, i.e. two per month. Some of these teeth are thinned out an arc of a circle 18a concentric with the axis of this annual wheel 18, others are not. The thickness of thinned teeth of the annual wheel 18 is therefore reduced for allow these teeth to pass under the lug 8a of the finger of calendar.
  • the thickness of the two teeth 4a of the tens pinion 4 corresponding to the digit "0" spans the entire the thickness of the teeth of the annual wheel 18, so that we are in gear position between these teeth and the pinion of tens 4.
  • the thickness of the others teeth of this tens gable is reduced so that they don't not meet the teeth of the annual wheel 18.
  • the teeth of the annual wheel 18 which are not thinned are five in number and correspond to five month of the year with less than 31 days.
  • every two teeth of the annual wheel are numbered according to the months of the years to which they correspond, from 01 for January to 12 for December.
  • the unthinned teeth of the annual wheel 18 therefore correspond to the months of February, April, June, September and November.
  • the date finger 8 drives the unit wheel 3 by one step.
  • the annual wheel 18 does not move the tooth corresponding to the month "10" being a thinned tooth which passes under the lug 8a of the date finger 8.
  • the next tooth of the wheel of the units 3 which will engage with the date finger is actually a tooth of the end pinion of months 12.
  • month pinion 12 can therefore turn on itself without driving the wheel of units 3, but by driving not against the tens pinion 4 of a step, tooth "0" of this pinion 4 engaged in the teeth of the annual wheel 18 again driving this wheel 18 a step. So the date that previously displayed "31" only changed the digit of tens, that of the units having remained motionless and the next calendar date is therefore "01".
  • the date mechanism described above therefore allows to pass automatically and without any correction from 01.03 on 28 or 29.02 of the following year.
