Definitions

  • the invention relates to a moon phase indicator mechanism for timepieces.
  • the moon phase indicating devices have existed for a long time and include a moon disk on which two yellow circles symbolizing the moon are drawn on a dark background, while said window of substantially semicircular shape in the dial has a separate base in two concave parts, all of which is well known to those skilled in the art.
  • the moon phase mechanism is formed of a wheel driven by an hour wheel and the disk on which are affixed the two representations of the moon.
  • a disadvantage of such a type of watch is that the indicator mechanism is operated once a day, which does not allow a realistic display of moon phases.
  • a conventional mechanism is complicated to integrate on a movement and can cause a component overload on the movement and thus increase the thickness of the watch case, which affects the aesthetics of the latter.
  • the moon phase indicator is activated at a given time, usually nineteen hours, to avoid a combination of functions at midnight and lead to excessive loss of amplitude of the sprung balance.
  • the invention particularly aims to overcome the various disadvantages of these known techniques.
  • an object of the invention is to provide a moon phase display allowing a more realistic display of moon phases.
  • Another object of the invention is to provide a moon phase mechanism that can consume energy and does not require activation at a predetermined time.
  • the invention also aims, at least in a particular embodiment, to provide a moon phase mechanism that is simple and inexpensive to implement.
  • a moon phase indicator mechanism for a timepiece equipped with a movement and a a dial
  • the moon phase indicator mechanism comprising at least one moon disk, and at least one moon phase wheel driven by the movement of the timepiece, the moon phase gear meshing with a phase wheel of a moon that at least indirectly and fixedly bears the moon disk, the moonphase wheel being in the form of a toothed ring so as to move the moon disk through the moon phase train around an axis A.
  • the object of the present invention by its various functional and structural aspects described above, makes it possible to obtain a relatively compact moon phase mechanism while providing a more realistic indication of the moon phase.
  • the invention also relates to a timepiece comprising a moon phase mechanism according to the invention.
  • a moon phase display device according to the invention will now be described in the following with reference to figures 1a , 1b , 2, 3 , 4 and 5 .
  • the watch 1 comprises a box 10 forming a housing in which is mounted the movement 3, the box being surmounted by a window 4 closing the front face of the box 10.
  • the watch also comprises a set forming the dial 11 centered on a axis A, the hands 12 cooperating with the dial to indicate the current time.
  • the assembly forming the dial 11 comprises a decorative upper part visible by the wearer of the watch, and a lower part which serves to maintain and guide the axes of the moon phase train.
  • the watch also comprises a mask 13 of axis A, disposed above the dial 11, the mask 13 partially obscuring the dial 11.
  • the watch is provided with a moon phase display device formed by an opening 14 made in the mask 13, and at least one moon disk 15 rotatably mounted between the mask 13 and the assembly 11.
  • at least one moon disk 15 is disposed on the outer diameter of the dial 11, so as to go around the dial 11 and the Moon disk 15 simulates a rising moon as it appears in aperture 14 and a decreasing moon as it leaves aperture 14.
  • the mask 13 can be mounted in a fixed manner and indicate, as desired, the moon phases in the northern hemisphere or in the southern hemisphere.
  • the mask 13 can be movably provided and can then move from a first position in which the moon disk 15 indicates the moon phases in the northern hemisphere, to a second position in which the moon disk 15 indicates the phases of moon in the Southern Hemisphere.
  • the moon phase mechanism comprises a single moon disk 15 which is arranged to go around the dial in a lunation cycle.
  • the mask 13 is centered on the axis A and has a circular opening 14 eccentric with respect to the axis A.
  • the moon phase mechanism is mounted on the dial side of a plate 16, between the plate 16 and the assembly forming the dial 11.
  • the moon phase wheel 20 is driven by the movement 3 of the watch 1, and more precisely by a wheel hours, not visible in the figures.
  • the cogwheel moon phase 20 is arranged to mesh with a moon phase wheel which at least indirectly and fixedly carries the moon disk 15.
  • the moon phase wheel is formed by a toothed ring 27 cooperating with the moon phase train 20 so as to move the moon disk 15 around the axis A.
  • the moon phase wheel 20 is mounted on the plate 16, and comprises a driving wheel 21 comprising sixty teeth and carrying a pinion 22 to twenty teeth, the pinion 22 engraining a wheel 23 to forty-five teeth carrying a pinion 24 to twenty teeth between the blades 231 and 232.
  • the pinion 24 engrains with a wheel 25 to forty-seven teeth engraining a pinion 26 with twenty teeth cooperating with the toothed ring 27 to a hundred seventy-five teeth receiving the moon disk 15.
  • Such an arrangement allows the moon disk 15 to perform a round of the dial in 29.5306 days, which corresponds exactly to a lunation cycle.
  • the transmission ratio between the hour wheel and the moon phase wheel is equal to 0.0169316.
  • the daily difference between the true moon and the moon of the mechanism is about fifty-six seconds, which corresponds to about one day's shift every one hundred and twenty-eight years, either a relatively precise mechanism.
  • the toothed ring 27 has a diameter substantially identical to that of the dial, centered on the axis A, so as to move the moon on the periphery of the dial 11.
  • the toothed ring 27 is provided with a toothing 270 formed on the inner edge of the toothed ring 27.
  • toothed ring 27 having a toothing on the outer edge.
  • the toothed ring 27 is mounted on an intermediate piece 50 supporting the moon disk 15, the moon disk 15 may for example be screwed by means of a screw 5 on the intermediate piece.
  • the intermediate piece surrounds the dial 11 and the movement 3.
  • the intermediate piece 50 visible on the figure 1 , in the form of a ring with a protruding peripheral rim on which is fixed the moon disk 15.
  • the intermediate part 50 rests on the plate 16 and may have rollers or any other means allowing the intermediate piece 50 to move in rotation while limiting friction on the plate 16.
  • the assembly formed by the moon disk 15, the intermediate piece 50 and the toothed ring 27 form a monobloc element once assembled together, this one-piece assembly being moved in rotation around the dial relative to the A-axis through the moon phase wheel 20.
  • the watch 1 is provided with a mask 13 movable about the axis A, the mask 13 can be moved by drive means controlled by the ring 2.
  • the moon phase indicator mechanism is provided with a device for correcting the position of the moon disk arranged to act on the moon phase train 20.
  • the correction device comprises a correction ring 2 arranged to cooperate by meshing with at least one corrective mobile unit of the moon phase gear train 20, and a friction system arranged to separate all or part of the moon phase gear train 20 during the correction of the position of the moon disk .
  • the correction device comprises a correction gear 40 arranged to mesh at least indirectly with the ring 2 when positioned in the correction position.
  • the correction pinion 40 meshes with a correction gear wheel 41 meshing with an intermediate gear wheel 42 secured to the toothed wheel 25 of the moon phase gear train 20.
  • the friction system comprises a friction wheel formed by the toothed wheel 23 of the moon phase train 20.
  • the pinion 24 supported by the friction wheel 23 rotates between the blades 231 and 232 without rotate the friction wheel 23.
  • the invention also relates to a timepiece equipped with such moon phase indicator mechanism according to the invention.
