Definitions

  • the present invention relates to this type of retrograde display but to for the purpose of achieving a display allowing animation of the dial of a shows and / or distinguishes between certain values of the same quantity, by example between day and night hours at a glance.
  • Another object of the present invention is to allow greater diversity in the design of a timepiece and in particular to realize a attractive display by the mobility of some of its elements.
  • the present invention relates to a sector display device retrograde which meets the aforementioned goals and which is distinguished by the The features set out in claim 1.
  • the attached drawing illustrates schematically and by way of example several variants of the display according to the present invention and two embodiments of the mechanism for actuating the retrograde hands of the display.
  • Figure 1 illustrates a first variant of the retrograde display device with two retrograde seconds hands, one indicating the seconds from 0 to 30 and the other from 30 to 60.
  • FIG. 2 illustrates a second variant of the retrograde display device with two retrograde hour hands, one showing the hours daytime from 6 a.m. to 6 p.m. and the other night hours from 6 p.m. to 6 a.m.
  • Figures 3 to 6 are plan views of a first embodiment the mechanism of the display device corresponding to the first or second variant of the display in different positions.
  • FIG. 7 is a section along line A-A in FIG. 5.
  • Figure 8 is a third variant of the display device.
  • Figure 9 is a fourth variant of the display device.
  • Figure 10 illustrates in plan a second embodiment of the mechanism of the display device corresponding to the third and fourth variants of display.
  • the principle of the new display device according to the invention is to display the same quantity, the seconds, minutes or hours for example of retrograde but not with a single graduation but with two partial graduations, each preferably indicating half of the indication maximum of the displayed quantity, each cooperating with a needle retrograde.
  • Timepiece 1 has a graduation traditional circular 2 from 1 to 12 with which an hour hand cooperates 3 and a minute hand 4.
  • the seconds display has two ticks, a first 5 of 0 at 30 seconds and a second 6 from 30 to 60 seconds cooperating one 5 with a first needle 7 and the other 6 with a second needle 8, both driven by a retrograde mechanism.
  • the retrograde mechanism actuating the hands 7, 8 of this display comprises a snail cam 9 comprising a part of approximately 180 ° cylindrical and another part of approximately 180 ° whose diameter increases.
  • This cam 9 is driven by the clockwork movement due to a revolution per minute in a manner known per se.
  • This mechanism also includes a first pinion 10, carrying the first needle 7, subjected to the return action of a first spiral spring 11 tending to keep this hand 7 in the display position of zero seconds.
  • This first pinion 10 meshes with the toothed sector 12 of a first lever 13 pivoted at 14 and the other end of which has a spout 15 held in abutment against the cam 9 by the effect of the spiral spring 11.
  • This mechanism also includes a second pinion 16, carrying the second needle 8, subjected to the return action of a second spiral spring 17 tending to keep the hand 8 in the display position for 30 seconds.
  • This second sprocket 16 meshes with a toothed sector 18 of a second lever 19 pivoted at 20 and of which the other end has a spout 21 held in abutment by the second spring hairspring 17 against cam 9.
  • the support points of the spouts 15 and 21 of the first and second levers 13, 19 on the cam 9 are located on a diameter of this cam and therefore offset angularly 180 °.
  • the mechanism located in the position illustrated in FIG. 3.
  • the spout 15 of the first lever 13 is located at the end of the cylindrical portion of the cam 9 while that the spout 21 of the second lever is at the start of this cylindrical portion of cam 9.
  • Cam 9 moves clockwise and in one half turn of this cam 9 the first hand 7 goes from 0 to 30 seconds on the graduation 5, the first lever 13 being actuated by the cam 9 while the second lever 9 moves along the cylindrical portion of the cam 9. The mechanism then occupies the position illustrated in FIG. 4.
  • the needle 7 remains stationary and it is the second hand 8 which goes from 30 to 60 seconds driven by the second lever 19 and the second pinion 16. Then a hundredth of a second later, the second hand 8 returns to 30 seconds from graduation 6 and the first hand 7 is ready for a new movement from 0 to 30 seconds next to the first graduation 5 (figure 6).
  • a double retrograde display was thus produced for a single value at display working alternately and actuated by a single cam.
  • FIG. 2 illustrates a second variant of the display device comprising a first graduation of the hours 22 cooperating with the hand 7 going from 6 hours to 6 p.m., i.e. daytime hours, and a second graduation of 23 hours cooperating with hand 8 going from 6 p.m. to 6 a.m., i.e. night hours.
  • the timepiece has on its dial a circular minute scale 24 cooperating with a minute hand 25.
  • the mechanism is identical to that illustrated in Figures 3 to 7 with reference to the first variant of the display device, the cam 9 being driven clockwise one revolution in twenty-four hours by the watch movement.
  • Figures 1 and 2 the retrograde display of seconds, respectively hours, has two graduations in the form of circle sector arranged between the center of the dial and the pivot point of the needle 7, 8 corresponding and having a concave shape directed towards outside the dial.
  • the third variant of the dual retrograde display illustrated in Figure 8 has a first graduation of 26 seconds and a second graduation seconds 27 cooperating respectively with the first 7 and second needle 8. These graduations are in the form of a sector of a circle and extend substantially parallel to the 2 hour scale.
  • the mechanism driving the needles 7, 8 is identical to that described with reference to Figures 3 to 7 except for the more angled shape of the first and second levers 13, 19, that the centers of rotation of the needles 7, 8 are closer to one of the other and that needle 7 is on the right and needle 8 on the left.
  • the operation of the mechanism is the same as that described above.
  • the last variant of the display device illustrated in FIG. 9 comprises a 28 daytime graduation and a 29 nighttime graduation substantially concentric with the 24 minute scale and located at the top respectively at the bottom of the dial.
  • the first and second needles 7, 8 are actuated by cam 9 as before.
  • the mechanism illustrated in the figure 10 is simply angularly offset by 90 °.
