Definitions

  • This date mechanism of a timepiece comprises a motive indicator unit with ten teeth or a multiple of ten and a mobile indicator tens equipped with four teeth or a multiple of four, a kinematic connection between the mobiles indicators of the units, respectively tens for moving the mobile indicator tens every ten steps of the mobile unit indicator and a mobile drive of the mobile indicator units, connected to the indicator gear of the timepiece.
  • the calendars displayed in watch windows and in particular wristwatches are often too small for a large number of users.
  • the first type is represented by the documents CH 310559 , EP 529191 , CH 688671 and EP 1070996 .
  • These are mechanisms consisting of two disks, one for the tens, the other for the units. These disks can be superimposed, coaxial or lie on either side of the actuating device which comprises a wheel 31 positions indexed by a jumper.
  • This 31-position wheel carries two other wheels, one driving the units with 30 teeth, the 31 st being replaced by a corresponding space, the other driving the tens has only 4 teeth spread over a circumference of the same diameter as the wheel of thirty-one teeth.
  • This type of mechanism has several disadvantages. Or the display disks are next to each other and two separate windows are needed and relatively distant from each other so as not to see the increasing spaces between the edges of the disks, or these disks are superimposed and the numbers of tens and units appear on two different levels, which is not nice and does not make reading easy.
  • This type of mechanism comprises three jumpers, so that it takes a relatively high torque to drive the date, thereby reducing the torque transmitted to the exhaust.
  • the drive device When the drive device comprises a movable 31 teeth, it occupies a large area.
  • This unit disk should be as large as a normal date disk and despite this, the size of the numbers will be limited. This system also implies that the date is six o'clock or noon. Indeed, if one wants that the figures are relatively large, it is necessary to orient them radially, so that they would be lying if they appeared through a window arranged to three hours. Finally in this case the disks are also superimposed.
  • the control mechanism is relatively complex and the display is on two levels, with the aforementioned disadvantages.
  • the last type of mechanism is illustrated by the CH 578202 and the CH 690515 . It uses two disks that are controlled by Maltese crosses and flip-flops that make this mechanism relatively difficult to adjust.
  • the object of the present invention is to remedy at least in part the disadvantages of the aforementioned solutions.
  • the subject of the present invention is a date mechanism of a timepiece according to claim 1.
  • This mechanism has several advantages, among which we can cite the small number of parts, the absence of flip-flops, the presence of two jumpers only, which work together only every ten days, thus reducing the energy loss of the movement.
  • All components of the mechanism can be made by cutting by generation, which is a manufacturing process to obtain very precise geometries with very good surface conditions, ensuring a very good performance of force transmissions in the mechanism.
  • the mobiles of the units and tens are constituted by coplanar concentric disks, so that the space between these two disks can be small and of constant width so as not to have to be hidden, making it possible to display the numbers of the units and dozens in a single window.
  • the units disk may comprise only ten digits.
  • This disc may be small, although the numbers it carries may be much larger than a conventional record 31 days, especially if this disc is coaxial in the center of the movement.
  • the date mechanism illustrated in FIG. 1 comprises two disks, a disk of the units 1 carrying ten digits or a multiple of ten intended for the display of the units, a tens disk 2 bearing four digits or a multiple of four intended for the display of the tens.
  • the digit "0" of the tens disk 2 can be deleted and replaced by a blank space.
  • the two disks 1 and 2 are concentric and allow the display of the numbers of the units and tens through a single window.
  • the disk of the units 1 is integral with a gear wheel units 3 which has 10 teeth or a multiple of ten.
  • the tens disk 2 is integral with a pinion of tens 4 ( Figure 2) which has four teeth or a multiple of four.
  • the pinion of the tens 4 and the wheel units 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 disks 1, 2 bearing the date numbers are coplanar, as can be seen in Figure 6.
  • the wheel of the units 3 is connected to the hour wheel clock hour indicator (not shown) which makes two turns in 24 hours by an intermediate wheel which drives a calendar wheel 7 at a rate of one turn in 24 hours .
  • This calendar wheel 7 carries a date finger 8 which drives the wheel units 3 a step every 24 hours.
  • a return 10 carried by a pin 10a integral with the turntable of the timepiece meshes with the tensile pinion 4.
  • This reference 10 is located on the path of a pin 9 carried by the wheel units 3, so that this return 10 is driven one step every turn of the wheel units 3 and itself drives the pinion of tens 4 also a step.
  • the dozens gear drive 4 coincides with the passage of the disk of the units 1 from "9" to "0".
  • the wheel of the units 3 carries a mobile auxiliary constituted by a pinion end of month 12, a tooth is positioned by a cam 15 integral with the tens pinion in place of a recessed tooth 11 of the wheel units 3.
  • Each tooth of the end of month pinion 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 the friction to a minimum between this cam 15 and the end of month gear 12.
  • the cam 15 has a clearance 15a located between two teeth of the tens gear, corresponding to the passage of the digit "3" to the digit "0" of the tens disk 2. With this cam 15 and its clearance 15a, the pinion of end of month is blocked angularly with respect to the wheel of the units 3 during the change of tens figures as long as a portion of the cam 15 intersects the trajectory of a roller 14, which is the case during changes of tens, except when changing from "31” to "01” which corresponds to the recess 15a of the cam 15, so that in this case, the end of month gear 12 can turn one step, the wheel units 3 remaining motionless. As a result, the tens disk changes from “3” to "0", while the disk of the units remains on the number "1" which corresponds to the number of the units of the days "31” and "01".
  • Two positioning jumpers 16 and 17 respectively cooperate with the wheel of the units 3 and with the pinion of the tens 4.
  • the jumper 16 of the wheel of the units 3 which is thicker, is capable of developing a larger than the jumper 17. This makes it possible to keep the wheel of the units 3 immobile during the passage of the tens disk from "3" to "0" between the "31" and the "01".
  • FIG. 3 shows the date mechanism when the disks of the units 1 and 2 show "30", that is to say that the pin 9 integral with the wheel of the units 3 rotating in the direction of the arrow located on this wheel 3 has just advanced the reference 10 as well as the pinion tens of one step in the direction of their respective arrows, to move from the position of Figure 2 to that of Figure 3.
  • FIG. 4 shows the position of the mobiles of the date mechanism when the two disks 1, 2 display "31". Note that in this position, a roller 14a of the end of month gear 12 is in front of the clearance 15a of the cam 15. Thus during the transition from the position of Figure 4 to that of Figure 5, the finger of date 8 can then rotate the end of month gear 12 by one step. This being no longer blocked by the cam 15, the wheel of the units 3 then remains stationary. Thanks to this month-end gear and to the cam 15, the date can be passed directly from "31" to "01".
  • Figures 7 to 11 show how one can take advantage of this feature of the date mechanism described so far to obtain an annual calendar based on a new concept according to which the date display automatically changes automatically from 01.03 to 28 or 29.02 of the next year, without ever having one or the other of the disks or the two disks simultaneously move more than one step per 24 hours.
  • the basic mechanism described above already makes it possible to make the transition from "31" to "01” by changing only the disk tens of a step and maintaining the disk units 1 still . Then just find a way to move the two disks one step at a time from "30" to "01” and then we have a very simple annual calendar, capable of implementing this clever date change process with all the advantages listed above.
  • the annual wheel 18 has twenty-four teeth, two per month. Some of these teeth are thinned outside an arc 18a concentric to the axis of this annual wheel 18, others are not. The thickness of the thinned teeth of the annual wheel 18 is reduced to allow these teeth to pass under the lug 8a of the calendar finger. The thickness of the two teeth 4a of the tens pinion 4 corresponding to the digit "0" extends over the entire thickness of the teeth of the annual wheel 18, so that one is in the gear position between these teeth and the tens gear. On the other hand, the thickness of the others Teeth of this pinion tens are reduced so that they do 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 the five months of the year having less than 31 days.
  • all the two teeth of the annual wheel are numbered according to the months of the year to which they correspond, from 01 for January to 12 for December.
  • the unthinned teeth of the annual wheel 18 correspond to the months of February, April, June, September and November.
  • the date finger 8 drives the wheel of the units 3 by one step.
  • the annual wheel 18 does not move the tooth corresponding to the month "10" being a tapered tooth which passes under the lug 8a of the calendar finger 8.
  • the next tooth of the wheel of the units 3 which will come into engagement with the date finger is actually a tooth of the pinion end of month 12.
  • the date finger 8 will cause the tooth of the pinion end of month 12, it is no longer prevented from rotating by the cam 15, since the roller 14 which normally abuts against this cam 15 is vis-à-vis a clearance 15a of the cam.
  • the end of month gear 12 can therefore turn on itself without driving the wheel of the units 3, but by driving not against the pinion tens of one step, the tooth "0" of the pinion 4 engaged in the toothing of the annual wheel 18 again driving the wheel 18 one step.
  • the date that previously displayed "31" has changed only the tens digit, that of the units being immobile and the next date is "01".
  • the date mechanism described above therefore allows to go automatically and without any correction from 01.03 to 28 or 29.02 of the following year.
