Definitions

  • the present invention relates to a moon phase display mechanism. More precisely, the moon phase display mechanism according to the invention is intended to equip a portable object of small dimensions such as a timepiece, in particular a wristwatch.
  • Timepieces in particular wristwatches, equipped with a moon phase display mechanism have been known for a long time.
  • These moon phase display mechanisms are nevertheless more decorative than they provide information allowing the owner of the watch to easily determine in which quarter of the moon it is located.
  • the simplest moon phase display mechanisms include a needle indicator that points to the different representations of the phases of the moon (first quarter, full moon, last quarter, new moon).
  • Other known moon phase display mechanisms include a disc which carries two representations of the Moon, part of this disc being visible through an opening of suitable shape made in the dial of the watch and successively revealing a waxing moon. , a full moon, a waning moon and a new moon.
  • Such a presentation of the different phases of the Moon is very advantageous from an aesthetic point of view; nevertheless, the way in which the Moon is represented has only a distant relation to the way in which the lunar star appears in the sky.
  • Yet another moon phase display mechanism includes a two-color sphere which rotates completely on itself with each lunar cycle. Such a moon phase display mechanism makes it possible to represent the face of the Moon in a realistic.
  • Such a moon phase display mechanism uses a sphere to represent the different quarters of the moon, it is thick and takes up a large space, so that it is difficult to integrate into a movement of the moon. horology, in particular a wristwatch.
  • the object of the present invention is to provide a moon phase display mechanism which provides a moon phase display which is in particular more faithful to reality and more easily understandable for the owner of the watch.
  • the present invention relates to a moon phase display mechanism driven by a clockwork movement, this moon phase display mechanism comprising a transparent support provided with an upper face and a lower face. which extends at a distance from the upper face, a representation of the Moon being transferred, for example by printing or by engraving, on one of the upper or lower faces of this transparent support, a substrate being placed under the transparent support, at a distance from the underside of the latter, the moon phase display mechanism also comprising drive means driven by the clockwork movement and which are arranged to move a shutter between the transparent support and the substrate, 'shutter and the substrate exhibiting inverted display contrasts with respect to each other, the shutter being moved from an initial position to a final position for a duration of a lunar cycle, by way to reveal day after day the aspect of the Moon which passes from the new moon to the first quarter moon, then from the first quarter moon to the full moon, then to the last quarter moon and finally to the new moon, the shutter being recalled from its final position to its initial position at the end of the lunar
  • the drive means comprise a rectilinear rack which is driven by clockwork and with which the shutter is fixedly coupled in translation.
  • the present invention provides a moon phase display mechanism making it possible to display the different aspects of the Moon day after day in an original and easily intelligible way by the user.
  • the representation of the Moon which is provided by the moon phase display mechanism according to the invention is very close to the real aspect of the Moon in the sky, so that it is much simpler for the user to determine what period of the lunar cycle the Moon is in.
  • the moon phase display mechanism according to the invention is also thinner than those using a sphere rotating on itself, and therefore easier to integrate into a timepiece movement, in particular of a wristwatch.
  • its representation is always visible to the owner of the watch.
  • the mechanism for displaying the phases of the moon makes it possible to obtain a representation of the different phases of the realistic Moon, formed by two surfaces of different colors and separated by a terminator, that is to say say the curve that separates the illuminated part from the dark part of the Moon, whose profile is very realistic and very faithful to what the user can see when observing the Moon in the sky. This is particularly the case during the first and the last quarter moon, when the optical distortions are almost zero and when the terminator thus appears perfectly rectilinear.
  • the transparent support is in the form of a lens of plano-concave shape delimited upwards, on the side of the observer, by a planar surface which receives the representation. of the Moon, and delimited downwards by a concave surface to which a profile is preferably given but not necessarily aspherical, this plane-concave lens being combined with a shutter to which a curved profile is given, preferably of the hyperbolic type.
  • the observer sees a terminator, that is to say the curve which separates the illuminated part from the dark part of the Moon, the profile of which is very realistic and very faithful to what the user can see when observing the Moon in the sky.
  • the moon phase display mechanism is more compact than a moon phase display mechanism using a sphere and thus can be accommodated in a smaller volume such as that of a one-piece box. watchmaking of the wristwatch type.
  • the moon phase display mechanism according to the invention is half the thickness of a moon phase display mechanism using a sphere.
  • the moon phase display mechanism according to the invention does not impede the movement of displacement of the hands on the surface of the dial.
  • the present invention proceeds from the general inventive idea which consists in transferring a representation of the Moon on one or the other of the two upper and lower faces of a transparent support which is arranged above and at a distance from a substrate, with the interposition of a shutter between the transparent support and the substrate.
  • the face of the Moon can be represented in a color similar to that of the substrate, while the shutter and the substrate have inverted contrasts: if the substrate is light, then the shutter will be dark and, conversely, if the substrate is dark, the shutter will be bright.
  • the representation of the Moon and the substrate are dark and that the shutter is clear
  • the representation of the Moon which is above the dark substrate is not perceptible to the observer.
  • the representation of the Moon gradually becomes perceptible by the user.
  • the present invention thus provides a more compact mechanism than moon phase display mechanisms which include a sphere and which allows moon phases to be displayed in an original and much more realistic manner than most devices allow. prior art moon phase display. Therefore, it is much easier for the observer to understand what period of the lunar cycle he is in.

  • the moon phase display mechanism 1 is driven by a clockwork movement, that is to say a mechanism whose the operation depends on the division of time. More precisely, the clockwork movement comprises a timer mobile, a pinion of which (not visible in the figures) drives a 24 hour wheel 2 which, as its name suggests, is arranged so as to perform one complete revolution per day.
  • the 24-hour wheel 2 carries a finger 4 on an axis 6 of which this finger 4 is mounted to rotate freely.
  • the finger 4 is mounted on the axis 6 with a slight axial play thanks to a ring 8 engaged on this axis 6.

It is therefore understood that when the pin 10 abuts against an inner wall 14 of the oblong hole 12, it is rotated by the 24 hour wheel 2 and in turn drives the finger 4 which, too, makes a full revolution in 24. hours.

  • jumper 26 passes, against the return force of the lower spring 30, from a hollow between two consecutive teeth of the toothing 28 of the star 24 to the immediately following hollow of this toothing 28 By falling back into the following hollow, jumper 26 allows star 24 to complete its advance of one step and again ensures the precise positioning of this star 24.
  • this manual correction device comprises a second rocker 40 pivoted about an axis 42 and which comprises an actuating means 44 such as a pin at an end opposite to the axis. pivot 42.
  • This second rocker 40 comprises for example a folded area 46 against which comes to rest a corrector (not visible in the drawing) when the latter is actuated against the elastic return force of a spring by the owner of the wristwatch from outside the volume of the watch case.
  • the second lever 40 pivots about its axis 42 and in turn controls the pivoting of the first lever 16 so as to cause the star 24 to advance by one step.
  • This advance of the star 24 takes place under the same conditions as those described above when the first lever exceeds the top 34 of the profile 20 of the finger 4.
  • a complete revolution of the star 24 corresponds to two successive lunar cycles, a lunar cycle corresponding to the time which elapses between two new successive moons and which is also called month lunar.

  • a first rake 62 provided with a toothed sector 64 is also provided with a feeler nose 66 by which it continuously follows the profile 58 of the cam 52. Shortly before the start of a new lunar cycle, for example at around midnight, the feeler tip 66 of the first rake 62 is at the top of the profile 58 of the cam 52 (position ⁇ - figure 4A ), then falls along the step 60 of the cam 52 (position D - figure 4B ). During this movement, the first rake 62 which, by its toothed sector 64, is in permanent engagement with a third pinion 68, turns this third pinion 68 clockwise by one. quantity corresponding to the fall of the feeler nose 66 along the step 60.

To this end, by pivoting, the lower wheel 74 drives the rectilinear rack 80 in translation and pushes it back into a first extreme position E shown on figure 8A which corresponds to the start of a new lunar cycle. Subsequently, when, after having fallen along the indentation 60 of the cam 52 at the start of the lunar cycle, the feeler nose 66 begins again to follow the profile 58 of the cam 52, the feeler nose 66 is gradually pushed back into the clockwise to a second extreme position F (see figure 8B ), so that the third pinion 68, and therefore the wheel 70, rotate counterclockwise.

  • the aspherical plano-concave lens 108 is made of a transparent material whose refractive index is preferably between 1.60 and 1.85, with an optimum value in the vicinity of 1.78. This value was chosen after numerous tests which have made it possible to observe that, the higher the value of the refractive index of the material in which the lens is made, the more it was necessary to approach the lens of the shutter 94 so that this the latter is not visible to the observer through this lens.
