Definitions
- This timepiece date mechanism includes a mobile unit indicator with ten teeth or a multiple of ten and a tens indicator mobile with four teeth or a multiple of four, a link kinematics between the mobile indicator units, respectively tens to move the mobile one step tens indicator every ten steps of the mobile indicator units and a training mobile for the indicating mobile of the units, linked to the gear train of the room watchmaking.
- the first type is represented by the documents CH 310559, EP 529191, CH 688671 and EP 1070996. These are mechanisms formed by two discs, one for the tens, the other for the units. These discs can be superimposed, coaxial or be located on either side of the actuating device which comprises a wheel with 31 positions indexed by a jumper. This 31 position wheel carries two other wheels, one driving the 30-tooth units, the 31 st being replaced by a corresponding space, the other driving the tens has only 4 teeth distributed over a circumference of the same diameter as the wheel of thirty-one teeth.
- This type of mechanism has three necklaces, 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 includes a mobile 31 teeth, it occupies a large area.
- This unit disk should be as large as a disk of normal date and despite this, the size of the numbers will be limited. This system also implies that the date is found at six o'clock or noon. Indeed, if we want 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 at three hours. Finally in this case the discs are also Bunk.
- the control mechanism is relatively complex and the display is done on two levels, with the disadvantages above.
- CH 578202 and CH 690515 The last type of mechanism is illustrated by the CH 578202 and CH 690515. It uses two discs which are ordered by Maltese crosses and seesaws that make this mechanism relatively difficult to adjust.
- the object of the present invention is to remedy the less in part to the disadvantages of the above-mentioned solutions.
- the present invention relates to a mechanism timepiece calendar according to claim 1.
- This mechanism has several advantages, among which we can cite the small number of pieces, the absence of flip-flops, the presence of two necklaces only, which does not work together only every ten days, thereby reducing loss of energy from movement.
- the space occupied by this mechanism is reduced, in particular on the surface, insofar as it does not use thirty-one teeth drive wheel.
- All components of the mechanism can be realized by cutting by generation, which is a manufacturing process allowing to obtain very precise geometries with very good surface conditions, guaranteeing very good efficiency of force transmissions in the mechanism.
- the date mechanism can then be move in both directions of rotation of these toothed organs without any risk of deterioration or blockage, as this can happen with rocker systems.
- the motives of the units and dozens consist of concentric coplanar discs, so the space between these two discs may be small and of constant width so as not to be hidden, to display the unit and tens figures in one window.
- the disc of the units may not include than ten digits.
- This disc can be reduced in size, although the figures he wears may have a size far superior to that of a classic 31-date disc, especially if this disc is coaxial in the center of the movement.
- 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 unit wheel 3 carries an auxiliary mobile constituted by a pinion of end of month 12 a tooth of which is positioned by a cam 15 secured to the tens 4 pinion 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 "01".
- Figure 3 shows the date mechanism when the disks of units 1 and tens 2 display "30", that is to say that the pin 9 secured to the wheel of the units 3 rotating in the direction of the arrow on this wheel 3 has just advanced the reference 10 as well as the sprocket of the tens 4 of a step in the direction of their arrows respective, to pass from the position of figure 2 to that of Figure 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.
- 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.
