    The present invention relates to timepieces, wristwatches, pocket watches or clocks provided with an orbital moon phase display embarked on a rotating disk.
    [0002] For example, an orbital display of moon phases such as that of the Richard Lange Perpetuai Calendar Terraluna watch is known. This orbital display has the disadvantage that the orientation of the lunar display changes according to the angular position of the rotating disk.
    The object of the present invention is to provide a timepiece having an orbital moon phase display whose orientation remains constant or substantially constant with respect to the timepiece box regardless of the angular position of the rotating disk.
    The present invention relates to a timepiece provided with an orbital display according to claim 1.
    The accompanying drawing illustrates schematically and by way of example a timepiece provided with an orbital moon phase display according to the invention.<tb> Fig. 1 <SEP> illustrates the timepiece provided with its orbital moon phase display.<tb> Fig. 2 <SEP> illustrates in section and in perspective the rotating disk of the timepiece carrying the orbital display.<tb> Fig. 3 <SEP> is a plan view of the rotating disk and the moon phase display mechanism, the sky dial being removed.<tb> Fig. 4 <SEP> is a schematic illustration showing that the orientation of the moon remains virtually constant regardless of the angular position of the rotating disk carrying the moon display.
    The timepiece illustrated in the drawings comprises a box 1 enclosing a mechanical clock movement that can be reassembled and set time with a ring 2 accessible from outside the box 1.
    In the view of FIG. 2, the lower face of the movement comprises a fixed wheel 3 integral with a fixed part of the movement, platinum or bridge, the hub 4 constitutes a passage for passing the axes of the needles of a time display. The inner race 5 of a ball bearing is fixed coaxially to the fixed wheel 3 on its hub 4 and the outer race 6 of this ball bearing is attached to a rotating disc 7 so that the rotating disc 7 can rotate. coaxially with the fixed wheel 3. This rotating disc 7 has a central hole giving passage to the switch of the movement. This rotating disc 7 is kinematically connected to a power take-off of the watch movement for its rotational drive at a speed appropriate for a particular display, for example a representation of the star sky.
    This rotating disc 7 carries the mechanism for displaying the phases of the moon which comprises a support 8 located on the rotating disc 7 (FIGS 2 and 3) and pivoted on the latter integral with a support gear wheel 9 which is arranged under the rotating disk 7. This toothed support wheel 9 is kinematically connected to the fixed wheel 3 by means of a reference 10 pivoted on the rotary disc 7.
    The carrier 8 carries a moon disk 11 disposed in a plane parallel to the upper surface of the support 8 but at a distance therefrom. The support 8 also carries a shutter 15 of the moon disk 11 and a drive mechanism of this shutter.
    More particularly, in the illustrated embodiment the shutter drive mechanism 15 comprises a moon cam 12 pivoted on the support 8 and disposed therebetween and the moon disk 11. A rocker 13 pivoted on the support 8 has a first spike-shaped end or feeler 13.1 cooperating with the snail-shaped surface of the moon cam 12 and a second rack-shaped end 13.2 engaged with a moon cache wheel 14 also pivoted on the support 8 and whose axis 14.1 carries a pallet. This pallet comprises an arm, fixed to the axis 14.1 of the moon cache wheel 14, carrying a circular shutter 15 whose diameter is greater than that of an orifice 18.1 of a sky dial 18.
    The moon cam 12 is integral with a moon cam wheel 12.1 engaged with a pinion 16.1 of a first intermediate mobile 16, pivoted in the hollow axis of the support 8, having a wheel 16.2.
    A second intermediate mobile 17 pivoted on the rotary disc 7comporte a first wheel 17.1 in engagement with the support gear 9 and a second wheel 17.2 engaged with the wheel 16.2 of the first intermediate mobile 16.
    The orbital moon phase display mechanism further comprises a sky dial 18, carried by the rotating disc 7, having on its upper face the representation of the star sky of a hemisphere. This sky dial 18 has an orifice 18.1 centered on the moon disk 11. The shutter 15 of the pallet of the moon phase mechanism moves between the lower face of the sky dial 18 and the upper face of the moon disk 11.
    In the embodiment illustrated and described above providing an orbital moon phase display the rotating disk 7 is driven by the power take-off of the movement at a rate of one complete revolution in 23 hours, 56 minutes and 4 seconds corresponding to the sidereal rotation period of the earth.
    The gear ratio of the kinematic connection connecting the fixed wheel 3 to the support 8 by the reference 10 is such that the orientation of the support 8 during the rotation of the rotary disc 7 remains the same or substantially the same relative to the box of the timepiece. Thus, if for a given position of the rotary disc 7 a straight line is drawn on the support 8 parallel to the direction 6H-12H of the timepiece, this straight line will always remain substantially parallel to this direction 6H-12H of the workpiece. watchmaking regardless of the angular position of the rotary disk 7 with respect to the box 1 of the timepiece. In a preferred embodiment the pivot axis 14.1 of the pallet carrying the shutter 15 is located so that a straight line passing through this axis 14.1 and the axis of rotation of the support 8 is parallel to the direction 6H -12H of the watch case 1.
    The gear ratio of the kinematic link connecting the support 8 to the moon cam 12, comprising the first intermediate mobile 16 and the second intermediate mobile 17 is such that the moon cam 12 performs a complete revolution during the period synodic revolution of the moon that is to say in a lunar, which corresponds in practice to 29 days, 12 hours, 44 minutes and 2.8 seconds. The position of the shutter 15 of the pallet relative to the opening 18.1 of the dial can be corrected manually by a kinematic link (not shown) connecting the first intermediate mobile 16 to a correction member accessible from the outside of the box 1.
    When the spout 13.1 of the latch 13 is in contact with the low point of the moon cam 12 the shutter 15 of the pallet is located entirely to the right of the opening 18.1 of the dial sky 18, so it is invisible through this opening and the moon disk 11 is fully visible through it, the display indicates a full moon.
    During rotation of the rotary disk 7, the shutter 15 of the pallet controlled by the moon cam 12 and the rocker 13 moves and partially closes the opening 18.1 so as to display the decreasing moon phases, the new moon and the increasing phases of the moon until the beak 13.1 of the rocker 13 is in contact with the high point of the moon cam 12. At this time the display again indicates a full moon, l shutter 15 of the pallet being located on the other side of the opening 18.1 is again invisible. Then the shutter 15 of the pallet instantly returns to its initial position when the spout 13.1 of the latch 13 falls on the low point of the moon cam 12.
    In this embodiment it is considered that the organ of the orbital display is formed by the opening 18.1 of the sky dial 18 with the moon disk 11 visible through it and that its mobile member worn by the support 8 is formed by the shutter 15 of the moon hides palette. The moon disk 11 is uniformly decorated on its upper surface, and even if it rotates with the support 8, the wearer of the watch does not see this rotation.
    FIG. 4 illustrates the successive positions, every three hours, of the dial sky 18 for the same day. It can be seen that the orbital display of the moon phase remains in a substantially stable orientation, the crescent moon being all the time oriented in the same way with respect to the timepiece. This is achieved by the fact that the orientation of the support 8 always remains the same with respect to the box 1 of the timepiece regardless of the angular position of the rotating disk 7 and therefore the sky dial 18.
    In general, the orbital display comprises a dial 18 carried by a rotating disc 7 pivoted on the watch movement of the timepiece having a member of the moon phase display formed by the opening 18.1. . This display further comprises a moon phase display mechanism carried by a support 8 kinematically connected to the movement ensuring that during an angular displacement of the rotary disc 7 relative to the timepiece, the orientation of the support 8 remains the same with respect to said timepiece. A kinematic connection connects the moon phase display mechanism to the support 8 whose gear ratio is a function of the magnitude to be displayed or the duration of the lunation in the embodiment described.
    More generally, it goes without saying that the rotating disc 7 can rotate at any speed. For example, if the dial has no representation of the star sky the rotating disk 7 can be driven by the power take-off of the movement at a rate of revolution in 24 hours as shown in FIG. 4 or a revolution in 12 hours.
    Alternatively, the shape of the shutter 15 and / or its drive device may be different. The moon phase display mechanism may also be adapted so that the new moon is displayed when the shutter 15 of the disk 11 is not visible through the aperture 18.1 and the full moon is displayed when the shutter completely closes the disc 11. The colors and decorations chosen for the dial 18, the disc 11 and the shutter 15 of the pallet may also vary.
