    Field of the invention
    The invention relates to a display device of the lunar phase as a function of the position of the hemisphere in which the observer is on the ground.
    Background of the invention
    [0002] The moon phase indicating devices have existed for a long time and comprise a moon disk on which two yellow circles symbolizing the moon are drawn on a dark background, whereas said half-moon shaped window is substantially semicircular. circular in the dial has a separate base in two concave parts, all of which is well known to those skilled in the art. When rotating this kind of moon disk under the window, the different phases of the moon are displayed.
    For example, it is known from FR 2 862 143 to provide a watch equipped with such a device.
    A major disadvantage of such a type of watch is that the display of moon phases is only for a hemisphere. Thus the builders must provide two distinct references, one for the northern hemisphere and the other for the southern hemisphere, which involves two different montages and the storage of two different rooms as well.
    Summary of the invention
    The invention particularly aims to overcome the various disadvantages of these known techniques.
    More specifically, an object of the invention is to provide a moon phase display whose display can be adapted according to the position of the wearer in the northern or southern hemisphere.
    The invention also aims, at least in a particular embodiment, to provide a moon phase display that is simple and inexpensive to implement.
    These objectives, as well as others which will appear more clearly later, are achieved according to the invention with the aid of a moon phase display device comprising a dial having an axis A, a disk moon, a mask configured to mask all or part of the moon disk, drive means of the moon disk arranged to move in rotation the moon disk about the axis A.
    According to the invention, the display device comprises means for adjusting the position of the mask so that the mask can pass from a first position in which the moon disk indicates the moon phases in the hemisphere North, to a second position in which the moon disk indicates the moon phases in the southern hemisphere, the rotational displacement of the moon disk relative to the mask simulating the different phases of the moon.
    According to other advantageous variants of the invention:The mask is circular in shape of axis A and comprises an eccentric circular opening;the eccentric circular opening is towards the twelve o'clock when the mask is positioned for the northern hemisphere, and is towards the six o'clock when the mask is positioned for the southern hemisphere;the mask can take an intermediate position to indicate the moon phases in the Southern Hemisphere;the mask is integral with a toothed ring of the same diameter as that of the mask;the adjustment means comprise an adjusting ring and at least one adjusting wheel cooperating with the ring gear so as to move the mask from one position to another.
    The invention also relates to a timepiece comprising a moon phase display device according to the invention.

    Detailed Description of the Preferred Embodiments
    A moon phase display device according to the invention will now be described in the following with reference to FIGS. 1a, 1b, 2, 3 and 4.
    As illustrated in FIGS. 1a and 1b 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 includes a dial 11 and pointers 12 axis Â, the needles 12 cooperating with the dial 11 to indicate the current time.
    The watch also comprises a mask 13 of axis A disposed between the dial 11 and the indicator hands 12, 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 a moon disk 15, rotatably mounted behind the mask 13. The moon disk 15 is disposed on the outer diameter of the dial 11, so as to go around the dial 11 and that the moon disk 15 simulates an increasing moon when it appears in the opening 14 and a decreasing moon when it leaves the opening 14.
    The display device comprises means for adjusting the position of the mask 13 so that the mask 13 can pass 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 moon phases in the southern hemisphere.
    According to the invention, the mask 13 has a circular shape of axis A and the circular opening 14 formed in the mask is eccentric with respect to the axis A.
    Advantageously, the opening 14 may be positioned towards the twelve hours when the mask 13 is positioned to indicate the moon phases in the northern hemisphere. The mask 13 can be moved to position the opening 14 towards the six hours to indicate the moon phases in the southern hemisphere.
    One can also consider positioning the opening 14 in the direction of three hours to indicate the moon phases in the northern hemisphere, in the direction of nine hours to indicate the moon phases in the southern hemisphere.
    According to a variant of the invention, the mask 13 may take an intermediate position to indicate the moon phases in the southern hemisphere. For example, the mask 13 can be moved to position the opening 14 in the direction of eight hours.
    According to a first embodiment, not shown in the figures, the driving means of the moon disk 15 comprise a conventional moon phase wheel well known to those skilled in the art. Such a cog moon phase is formed of a driving wheel with a finger. The moon phase wheel is driven by a wheel of hours. The finger cooperates with a moon phase wheel so that the finger drives the moon phase wheel. Such an arrangement is well known to those skilled in the art and allows the moon disk 15 to rotate the dial in a lunation cycle.
    According to a second embodiment of the invention, not shown in the figures, the driving means of the moon disk 15 are formed by a moon phase gear comprising between the driving wheel and the phase wheel of moon, a star of seven carrying a pinion with sixteen teeth, driven by the finger, and a reference to sixteen teeth cooperating with the moon phase wheel and driven by the pinion with sixteen teeth. Such an embodiment is also well known to those skilled in the art.
    According to another embodiment, the driving means 20 of the moon disk 15 are mounted on the dial side and may comprise a driving wheel 21 comprising sixty teeth and carrying a pinion 22 with twenty teeth, the pinion 22 engraining a friction wheel 23 to forty-five teeth which receives a pinion 24 to 20 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 a toothed ring 27 to one hundred and 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.
    According to the invention, the mask 13 being operable in rotation by the user via adjustment means 30 of the position of the mask 13. The mask 13 is secured to a toothed ring 34, preferably of same diameter as that of the mask 13, configured to cooperate with the means for adjusting the position of the mask 13.
    As can be seen in FIG. 4, the mask 13 comprises a substantially circular flat portion 130 receiving the opening 14 and a hollow cylindrical portion 131 at the outer periphery, the flat portion 130 being housed between the dial 11 and the movement and the hollow cylindrical portion 131 is lodged between the side wall of the box and the movement.
    Advantageously, the toothed ring 34 can be secured to the mask 13 at the cylindrical portion by means of screws for example.
    According to one embodiment of the invention, the adjustment means 30 comprise a control member constituted by the ring gear 2, in connection with the mask 13. More specifically, the adjustment means 30 comprise the ring gear 2 and at least one adjusting wheel cooperating with the toothed ring 34 so as to move the mask 13 from one to a second position.
    As can be seen in FIGS. 2 and 3, the adjustment means comprise a first wheel 31 carrying a pinion 32 intended to cooperate with the crown rod 2, the first wheel 31 engraining with an intermediate wheel 33 which engraves itself the toothed ring 34.
    The invention also relates to a timepiece equipped with such a display device according to the invention.
    Of course, the present invention is not limited to the illustrated example but is susceptible of various variations and modifications that will occur to those skilled in the art.
