Definitions

  • the present invention relates to date display devices intended to equip timepieces of the type comprising a movement and hands driven by this movement and displaying the time.
  • One solution to this problem is to equip the device first and second display members mounted mobile in rotation on the movement, arranged under a dial provided with cutouts. These organs are respectively intended to display the units and the tens of the date by means of numbers, visible through these cutouts.
  • the device further comprises a movement controlled positioning and positioning mechanism and arranged to blow one and / or the other of the organs once per day.
  • Such a device is, for example, described in patent CH 310 559.
  • This device is controlled by a clockwork movement, by means of a wheel performing a tour in 24 hours.
  • the latter drives 1 / 31st of a turn, and once a day, a mobile with two superimposed wheels.
  • Organs display panels consist of two discs arranged side by side, one displaying the tens of the calendar and the other the units, the current calendar appearing in a cutout of the dial.
  • the mobile and the discs are arranged so that when the number units of the date displayed is equal to 0 or between 2 and 8, only the drive units is driven, when the unit figure is 9, the drives of the units and tens are both driven, when the figure of units is equal to 1 and the tens digit to 0, 1 or 2, only the disk of units is trained, and when the units digit equals 1 and the units digit tens to 3, only the tens disc is driven.
  • Such a device allows display the date using large numbers.
  • patent EP 0 619 035. It relates to an analog type electronic watch, in which the date is displayed by two hands. The first indicates the tens, in four positions making an angle of 90 ° between them, while the second displays the units, in ten positions evenly distributed over one revolution.
  • the purpose of the present invention is to allow a display of the date of particularly readable while contributing to the aesthetics of the room.
  • the display device which is intended to equip a timepiece of the type comprising a movement, a dial and hands, the latter being driven by the movement and displaying the time, has first and second display members, driven in rotation by movement, intended to display units and tens respectively of the date, and a drive and positioning mechanism motion-controlled and arranged to blow one and / or the other display once a day.
  • the first member is mounted on the movement, pivoting around an axis which is perpendicular and carries an index
  • the mechanism and the first organ are arranged in such a way that when the mechanism passes display of the units of the date with a value n to n + 1, n being a number integer between 1 and 9, the first organ traverses, clockwise, a angle equal to 30 °, and that, when n is equal to 1, the index is in a position corresponding to the position that an hour hand would occupy, pivoting around the axis of the first organ, when it is one o'clock.
  • the mechanism and the first member are arranged so that the latter performs a 90 ° jump when n is equal to 0, so that the index moves from the "nine o'clock" position to the position "noon", by the shortest route.
  • the first member is formed of a disc, carrying the index, and placed under the dial.
  • the latter includes nine cutouts arranged in a substantially concentric arc of a circle disc, the first cut occupying a position corresponding to "1 hour” and the following ones making an angle of 30 ° with respect to each other, reference to the center point of the circular arc, so that the last cut-out is in the "9 o'clock" position, so that the index of the first organ is visible through the cutouts.
  • the second display member is also formed of a disc mounted pivoting on the movement and which carries three indexes arranged in an arc
  • the dial also includes three cutouts arranged in an arc and the same radius as the arc formed by the indexes.
  • the tens display unit and the drive and positioning are arranged so that zero, one, two or all three indexes are visible through the three cutouts, depending on whether the number of tens equals 0, 1, 2 or 3.
  • the display mechanism and devices are arranged in such a way that when the number of the units of the date is equal to 0 or between 2 and 8, only the units disk is driven, when the unit number is 9, the unit disks and tens are all two driven, when the number of units is equal to 1 and the number of tens to 0, 1 or 2, only the units disk is driven, and when the number of units is equal to 1 and the tens digit to 3, only the tens disk is trained.
  • the watches shown schematically in Figures 1 and 2, include, classic way, a dial 10 and, placed at the front of this dial, hands 12 and 14 showing the hours and minutes respectively.
  • the watch is barrel-shaped. Its dial wears a turn of 16 hours formed numbers from 1 to 12, excluding 6. It is, moreover, provided with a set of nine cutouts 20 intended to display the units of date, and a set of three cutouts 22 for displaying the tens of the date, respectively arranged on two concentric circles occupying the space between the center and the 6 o'clock position of the dial.
  • the date is displayed by means of an index 24, intended to indicate the value of the digit of the units by its position and three index 26, intended to display the tens digit, this being equal to number of visible indexes.
  • the cutouts 20 define between them an angle of 30 °, that is the angle that runs the hour hand in one hour. In other words, if a needle for hours pivoted in the center of the concentric circles, it would be, in look of the first cut 20a, at 1 o'clock, of the second 20b, at 2 o'clock, etc.
  • the index 24 appears through one of the cutouts 20 and indicates the number of date units by its position, this is equal to 3 in Figure 1.
  • Two indexes 26 are visible through the first two cutouts 22a and 22b, to mean that the tens digit is equal to 2. In other words, the current date is equal to 23.
  • the cutouts 20 are in look at the numbers 1 to 9 of the hour circle 16, the cut 20f, close to the number 6, framing the index 24.
  • the units digit is therefore equal to 6.
  • the cutouts 22 are arranged in the zone between 11 hours and 1 hour, two indexes 26 appearing in cutouts 22a and 22b.
  • the figure of tens is therefore equal to 2.
  • the date displayed is therefore equal to 26.
  • cutouts 20 and 22 are round. he It is obvious that they can take other forms. So in the case of the example of Figure 2, these cuts could also, advantageously, have the shape of the number corresponding to its position and, thus, replace the lathe of hours 16.
  • Figures 3 and 4 show a watch movement, showing the date according to the embodiment of FIG. 1, the components of which occupy their position corresponding to the 29th of the month. These figures are differentiate by hiding or tearing off all or part of certain rooms.
