Definitions

  • the present invention relates to a date display mechanism for watch movement, in particular a large date display mechanism.
  • Needle watch movements that allow the display of the date of the date most often use a 31-position annular calendar disc, the dates from 1 to 31 being printed on these positions.
  • the date disc is indexed each day by one position, so that another date appears every day through a window in the dial.
  • Each indexing position thus occupies an angular portion of 360 ° / 31, on which a date with one or two digits must be indicated; the maximum size of the displayed numbers is therefore limited.
  • Jaquet SA International demand WO9913383
  • the disk of the units carries three times the sequence of digits from 0 to 9 plus an interlayer 1, corresponding to the sequence of units for the numbers from 0 to 31.
  • the branches of the cross carry the digits from 0 to 3 respectively.
  • a window on the dial is arranged to display both the portion of the cross covering the annular disk and the next digit of the units to the right of the cross.
  • the cross of the units occupies an important space in the center of the watch; this space is therefore unavailable for other displays, for example for the axes of auxiliary function needles such as chrono, power reserve, display of the day of the week, etc.
  • auxiliary function needles such as chrono, power reserve, display of the day of the week, etc.
  • the size of the cross of the tens, and therefore the maximum dimension of the date digits displayed is limited by the distance between the disk of the units and the axis of the seconds.
  • the tens star is driven by the annular disk units through a star meshing with the internal toothing of the disk units and retained by a jumper.
  • the star may sometimes be driven with sufficient energy for the jumper to pass directly from a tooth, or branch, to a non-neighboring tooth of the star.
  • the correspondence between the tens and the units is irremediably destroyed; the watch could for example display dates 32, 33, etc.
  • it is therefore necessary to use a retaining collar of the star actuated by a sufficiently strong spring; this solution however has the disadvantage of considerably increasing the power and the energy required for the change of date.
  • the motors must be oversized only to act on the jumper, and the power consumption is increased.
  • An object of the present invention is to provide a date display mechanism which avoids these disadvantages.
  • a date display mechanism for watch movement comprising a first mobile carrying a first sequence of digits and a second mobile carrying a second sequence of digits.
  • the two mobiles are arranged and arranged so that, at least for certain dates, the date displayed to the user corresponds to the combination of indications carried by the first mobile and indications carried by the second mobile, while for at least one other date the displayed date corresponds to the combination of two digits or a digit and a space carried by the same mobile.
  • the display mechanism of the invention is therefore a combination between a large date display mechanism, with two figures carried by two distinct mobiles, and a conventional date display mechanism for other dates, for which the single digit or two digits of the date are carried by the same mobile. This avoids, at least for some dates, the disadvantages of the display by two distinct mobiles, without having to give up the display of large dates.
  • This solution also makes it possible to balance the number of indications carried by the two mobiles, by reporting certain indications of units on the tens disk and / or certain indications of tens on the disk of the units, so as to be able to display dates of the largest possible size.
  • the two mobiles are preferably constituted by two concentric annular disks and preferably superposed. This avoids occupying the portions of the upper surface of the movement that could be used by other displays.
  • the date can be displayed at any angular position on the dial by replacing only the annular disks, without changing or moving the drive mechanism.
  • a date display mechanism for watch movement comprising a first mobile bearing a first sequence of digits, and a second mobile carrying a second sequence of digits.
  • the two mobiles are arranged and arranged so that, at least for certain dates, the date displayed to the user corresponds to the combination of indications carried by the first mobile and indications carried by the second mobile.
  • the second mobile for example the mobile carrying at least some tens, is driven by the other mobile, for example the mobile carrying at least some units, through a star held by a jumper.
  • An abutment member is arranged to prevent the jumper from passing directly from a tooth of the star to a non-adjacent tooth upon the change of date.
  • This solution has the advantage of reducing or eliminating the risk that the second disk is erroneously indexed by two positions instead of one when the date is changed, in particular during the manual correction of the date. It is thus possible to safely reduce the force of the spring acting on the retainer of the star, which reduces the energy and power required to change tens of the date.
  • the figure 1 shows a top view of the date drive mechanism according to a first variant of the invention; only the parts useful for the understanding of the mechanism have been represented in full lines for ease of understanding of the figure.
  • the mechanism comprises two mobiles formed in this example by two concentric annular disks 1 and 2 superimposed.
  • the first mobile 1, or ring of units carries a sequence of digits 10 ⁇ 1,2,3,4,5,6,7,8,9,0, 1,2,3,4,5,6,7 , 8,9,0,1,2,3,4,5,6,7,8,9 ⁇ .
  • the numbers are regularly spaced except for a larger interval between the last 9 and the first 1 which is sufficient to display a two-digit date, as will be seen later.
  • the dates are intended to be displayed at twelve o'clock on the dial; the figures of the units are thus arranged almost radially, so as to appear vertical when they are seen through a vertical window just to the right of the twelve o'clock position.
  • the second mobile, or tens ring is constituted by a second ring 2 concentrically rotating over the ring of the units 1, as can be seen in particular on the Figures 5 and 6 .
  • the dial 6 of the watch is at the bottom.
  • the second ring 2 bears the sequence ⁇ 0,1,2,30,31,0,1,2,30,31 ⁇ .
  • a vertical window 21 is stamped through the tens ring 2 to the right of the numerals 0, 1 and 2, making it possible to see the numbers carried by the ring of the units 1.
  • the second mobile 2 could be constituted by a non-annular element, for example by a cross or a star rotating above the first mobile 1, and provided with non-rectangular cutouts 21, for example as suggested in the document WO9913383 mentioned.
  • the mobile tens could carry a single sequence ⁇ 0,1,2,30,31 ⁇ , or more than twice this sequence.
  • a single sequence however has the disadvantage of requiring significant angular steps at each indexing of the mobile, while the display of a larger number of sequences necessarily leads to use smaller numbers.
  • the two mobiles could be concentric but of different diameters, and therefore not superimposed, or partially superimposed.
  • at least one of the two annular discs could carry cutouts in the form of internal or external radial flaps to cover the figures or indications carried by the other mobile on certain dates.
  • cuts provided in the various variants of the invention may also be constituted by transparent portions of one of the two mobiles.
  • the arrangement of the numbers 10, 20 and the inclination of the windows 21 depends on the position chosen for displaying the date on the dial; for example, to display the date at three o'clock, it is necessary to rotate the numbers 10, 20 as well as the windows 21 by 90 °. In this the numbers and the windows occupy a larger angular segment, so that a number of sequences different from two on the tens ring 2 may be adopted.
  • the angle of rotation depends, of course, on the angular position of the counter.
  • the date 3 displayed through the window 60 in the dial 6 is generally formed of a number 20 coming from the ring of tens 2 and a second digit 10 coming from the ring of 1, visible through a window 21.
  • the date 3 displayed to the user of the watch comprises two figures, both of which are carried by the tens ring. these particular dates, the problem of difference of depth between the digit of tens and the number of units.
  • the maximum date size displayed in a conventional large-date display corresponds to the maximum size of the numbers that can be displayed on both the tens and units mobile.
  • the ring of units 1 carries the sequence of digits 10 ⁇ 1,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7, 8,9,0,1,2,3,4,5, -6,7,8,9 ⁇ while the tens ring carries the sequence of digits 20 ⁇ 0,1,2,30,3,0 , 1,2,30,3 ⁇ , the '0' can also be replaced by spaces.
  • This configuration makes it possible to display all the dates by means of indications carried by the two mobiles 1, 2, with the exception of the date which is indicated by means of two figures carried by the tens ring 2.
  • the ring of units 1 carries the sequence of digits 10 ⁇ 1,2,3,4,5,6,7,8,9 ⁇ repeated three times while the ring of tens carries the sequence of digits 20 ⁇ 0 , 10,1,20,2,30,31 ⁇ .
  • This configuration allows you to display all the dates using of indications carried by the two mobiles 1, 2, with the exception of the dates 10, 20, 30 and 31 which are indicated by means of two figures carried by the tens ring 2.
  • the ring of units 1 carries the sequence of digits 10 ⁇ 1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8, 9,0,1,2,3,4,5,6,7,8,9,0 ⁇ while the tens ring carries the sequence of digits ⁇ 0,1,2,3,31,0, 1,2,3,31 ⁇ .
  • This configuration makes it possible to display all the dates by means of indications carried by the two mobiles 1, 2, with the exception of the date 31 which is indicated by means of two figures carried by the tens ring 2.
  • the dates corresponding to dates 1 to 9 are displayed using a single mobile; this allows for example to display this date with a single digit that can also be centered in the window 60.
  • the indication of the tens and the indication of the units can be displayed in two separate windows juxtaposed or arranged at different points of the dial, for example at ten o'clock and two o'clock.
  • the two mobiles are driven by the same electromechanical or mechanical motor (not shown) and set by the same crown; it would however also be possible to drive and / or adjust the two mobiles by two independent motors, or by a single motor but through two separate kinematic chains.
  • a pinion 44 actuated by the not shown motor drives a wheel 46 on the axis of which is mounted a pawl device 460 arranged to cause the rotation, each day, at midnight or at another time, the internal toothing 11
  • ring 1 is indexed every day by 360/31 degrees to perform one round per month of 31 days.
  • the number and the instant of the rotations of the tens ring depend on the sequences on the two mobiles 1 and 2, as can be seen by comparing the position of the stops 12 on the variants of Figures 1 to 4 .
  • the star 50 drives at each rotation a wheel 52 mounted on the same axis, which in turn actuates a wheel 53.
  • the wheel 53 is mounted on the axis of a wheel 54 meshing with the internal toothing 22 of the ring
  • the gear ratio between the wheels 50 and 53 is chosen so that the indexing angle of the ring 2 caused by a displacement of the star 50 corresponds to the angular distance between two numbers. tens.
  • the star 50 is retained by a jumper 51 pressed against the gap 502 between two teeth 501 of the star 50 by a spring 510.
  • the jumper prevents the star 50 from spinning freely, particularly when is driven by a stop pin 12.
  • a stop element 511 here constituted by a pin perpendicular to the plane of the watch, which moves in a slider 500 machined in the wheel 52.
  • the shape of the slider 500 prevents the pin 511 from jumping directly from a gap 502 to a non-adjacent gap between two teeth of the star 50; it thus surrounds the star 50 by marrying approximately its contours.
  • the first mobile 1 slides directly on the upper deck 9 of the movement of the watch, and is retained by a first plate 8 mounted over this bridge.
  • the second mobile 2 slides on an annular path over this first plate 8 and is retained by a second plate 7.
  • the dial 6 is fixed over the second plate and provided with a window 60 to display the dates carried by the first and / or second mobile.
