Definitions

  • the present invention relates to date mechanisms of the type with a large window facilitating the reading of the date.
  • Such a mechanism is described in the document WO98 / 50829 . It comprises an annular control wheel performing one turn per month, thirty-one steps and provided with two sets of teeth respectively driving a mobile display units and a display mobile dozens of the date.
  • the display mobiles are coplanar and arranged side by side inside the ring formed by the control mobile.
  • the fact that the display mobiles are coplanar limits their diameter, for a given diameter of the caliber equipped with the date mechanism, which causes a decrease in the size of the figures carried by these display mobiles and therefore reduces the readability of the display. display of the date.
  • the realization of the control wheel is delicate and complicated because of its three different teeth.
  • the published European patent application EP 1555585 also discloses such a mechanism comprising a control mobile in the form of a crown performing a lathe in one month in thirty-one steps daily and having two teeth. One of these teeth drives a mobile display of the units by a first gear and the other drives a display mobile dozens by a second gear, the two display mobiles being concentric.
  • This mechanism is complex, three-toothed control crown, two separate gear trains and two superimposed and concentric display disks. Such a mechanism is very cumbersome and complex.
  • the published patent application US 2006/0002237 also discloses such a mechanism comprising a drive crown performing a lap in thirty-one daily steps provided with three different teeth, a mobile display units comprising a star of ten cooperating with a toothing of the crown and carrying a display disc units.
  • a display mobile tens has a star tens meshing with the star of the units, and a tens disk. This star of ten is in addition driven by a second toothing of the driving ring by means of a pinion.
  • the two display disks are coplanar and tangent to each other.
  • the diameter of the display disks is reduced, decreasing the size of the numbers they carry and therefore readability.
  • the driving ring has three teeth and is therefore complex to achieve.
  • the patent CH 310559 also describes such a date mechanism comprising an intermediate mobile three boards driven at a rate of thirty-one steps per turn.
  • the first board of this intermediate mobile has thirty-one teeth and serves for its training;
  • the second board has thirty teeth and an empty space and cooperates with the star of a mobile unit display;
  • the third board has a toothing of four teeth and cooperates with the star of a tens display mobile.
  • Both display mobiles have coplanar and tangent display disks. The diameter of these discs is therefore limited and therefore also the size of the numbers they carry.
  • the object of the present invention is to provide a date mechanism of the type with a large window facilitating the reading of the date tending to obviate the aforementioned drawbacks of the previous embodiments.
  • one goal is to ensure that the date crown of an existing movement can be used as a motor without much modifications, that the kinematic connection between the calendar crown and the display mobiles is done as directly as possible and with mobiles to two boards maximum.
  • another goal is to allow a larger display of the date by ensuring that the diameter of the display disks is not limited to 0.5 times the diameter of the caliber equipped with this mechanism.
  • the present invention relates to a date mechanism characterized in that it comprises in combination a driving crown or date driven step by step and performing a complete turn in thirty-one steps daily, this date crown having uniformly distributed on its periphery, thirty pins and an empty space, one of said pins being longer than the others; a display unit of the date units comprising a disk units with numbers 0 to 9 of the date units and a star of the units of ten teeth cooperating with all the pins of the date ring; a mobile display tens of the date having a tens disk equipped with digits 0 to 3 tens of the date and a star of the tens co-operating with the single long pin of the date ring; an intermediate mobile comprising on the one hand a wheel of thirty teeth in engagement with the star of the units and on the other hand an intermediate star of three teeth cooperating with the star of tens and in that the disk of the units partially overlaps the tens disk so that for each stable position of these disks a digit of the
  • the Figures 1 and 2 of the appended drawing illustrate a basic watch movement or caliber equipped with a calendar with a large window according to the invention.
  • the date mechanism with a large aperture uses as a driving member the date ring 1 of the watch movement driven by its teeth. internal having thirty-one teeth 2 uniformly distributed on its inner periphery at a rate of one step per day. This crown of date 1 thus performs a complete turn in thirty-one days.
  • the drive of this date ring 1 by the watch movement is carried out in a conventional manner.
  • This date ring 1 is provided at its periphery with thirty pins 3 and with a vacuum space 4 distributed uniformly along this periphery, one of the three pins 30a 3 is longer than the others. These thirty pins 3, 3a are arranged on the same circumference.
  • This calendar crown is very easy to achieve because it has only internal teeth 2 for its drive and a single row of pins driven in its periphery.
  • the empty space 4 corresponds to twice the distance separating two adjacent pins 3 and thus two steps from the date ring 1.
  • This date ring is pivoted on the base gauge in the usual way.
  • the date mechanism also comprises a mobile units and a tens mobile.
  • the units mobile comprises a star of the units of ten teeth and a disk of the units 6 bearing on its upper surface the numbers from 0 to 9 of the calendar units uniformly distributed on its periphery. These figures are oriented substantially perpendicularly to a radius of the disk units tangent to the upper part of the figure.
  • the circumference of the disk of the units has facets 7 substantially parallel to each of the figures carried by this disk of the units.
  • the star of ten of the units 5 is located in such a way that its teeth are on the path of the pins 3, 3a during the rotation of the date ring 1.
  • the star of the units 5 is driven one step by one of the pins 3, 3a.
  • the empty space 4 passes in front of the star of the units 5 and it is not driven, the number 1 remains in the window 7 of the dial during two successive steps of the date ring 1.
  • a jumper 8 cooperating with the toothing of the star of the units 5 keeps the mobile units 5,6 in a stable angular position between two actuations by the date ring.
  • the mobile tens comprises a star of tens 9 of eight teeth and a tens disk 10 carrying two sets of numbers from 0 to 3 distributed uniformly on its periphery corresponding to the numbers of tens of date.
  • these figures are arranged in directions parallel to the diameters of the tens disk 9.
  • the star of the tens 9 has eight teeth located on the path of the pin 3a of greater length of the date ring 1
  • the star of the tens is driven by the crown of date 1 only once a month between the thirty-first and the first of the following month, that is to say during the step of the crown of date 1 where the star of the units 5 is not driven.
  • the date mechanism finally comprises an intermediate mobile having a first board 12 of thirty teeth meshing with the star of the units 5 and a second board 13 of three teeth cooperating with the star of the tens 9.
  • the star dozens 9 of the mobile tens 9,10 is driven four times a month, three times by the intermediate mobile 12, 13 between the nine and ten, the nineteen and twenty and twenty-nine and thirty of each month and once by the date crown between the thirty-one of a month and the first of the following month.
  • the principle of the present date mechanism is that the driving ring or crown date with thirty pins leads only units from the first to the thirty-first days of the month.
  • the tens are, they, driven by an intermediate mobile with thirty teeth on a first board driven by the star of the units and three teeth on a second board driving the star tens. From the thirty-first day of a month to the first of the month following the date crown brings with it its single long pin the star of tens only.
  • This date mechanism has many advantages.
  • the number of mobiles composing it four mobiles of which three of two boards only.
  • the driving ring or crown of date 1 is simple since it has a conventional internal toothing for its drive and a single row of pins forming the equivalent of two separate teeth necessary in the previous devices.
  • the intermediate mobile has only two boards and not three as often in the prior art.
  • the window 7 of the dial is located between 10H and 11H but this is not limiting.
  • Other locations for the display of the date can be chosen which can cause a change in the positioning of the numbers on the display discs and the arc distance between the long pin 3a of the empty space 4 of the crown of date 1 as well as the arc distance between the axes of the display mobiles, as well as the diameter of the boards of the intermediate mobile 12, 13.
  • the tens disk could be located partially above the disk of the units, but still these two disks overlap partially allowing to have disks with a diameter greater than 0.5 times the diameter of the caliber, thus saving more space for the figures carried by this disk.
