    Description
    TECHNICAL AREA
    The present invention relates to a mechanical clockwork movement and more particularly to a watch movement having at least one mobile dial.
    In more detail, the invention relates to a watch movement comprising a power source arranged to supply components forming at least one kinematic chain, the kinematic chain comprising a regulating system provided in particular with a rotating cage.
    The present invention also relates to a timepiece comprising such a movement. Such a timepiece can in particular be a watch such as a wristwatch.
    PRIOR ART
    [0004] Timepieces such as, in particular, wristwatches comprising one or more mobile dials have been known for a long time. Such mobile dials form a decor that varies over time. These dials can have a purely decorative function and / or allow to give the wearer of the watch, indications such as the phase of the moon or the stars and constellations currently visible for example. Such timepieces are described in particular in patents CH 677 305 and CH 700 261.
    It has also been for a long time, the control systems provided to improve the isochronism of the movement of the watch by making this movement less sensitive to its position. More particularly, the regulating system has the effect of moving the balance over time, so as to make it take different positions. The average of the isochronism defects as a function of the position of the movement is in principle closer to zero than the isochronism defects in a particular position of the movement. These control systems are known as whirlpools or carousels.
    There are also movements for a timepiece comprising both one or more mobile dials and a control system type tourbillon. Such movements are described in patents CH 699 784 and CH 702 507.
    In the movements described in these documents, two separate kinematic chains are provided. One of them starts from a cylinder and manages the operation of the regulating system. The other kinematic chain also starts the barrel and manages the displacement of the mobile dial or dials.
    Having two separate kinematic chains implies the need to use a relatively large number of watch components. This therefore implies a large volume and energy losses due to friction between the different watch components. This results in a loss of power reserve.
    SUMMARY OF THE INVENTION
    The movement for a timepiece according to the present invention proposes to provide an alternative solution for the setting in motion of one or more mobile dials, in a movement comprising at least one regulating system.
    More specifically, the present invention proposes to make a watch movement as defined in the preamble and characterized in that the rotating cage drives a mobile dial.
    According to this invention, a single kinematic chain is used both for the control system and for the rotation of a dial. As a result, it becomes possible to perform a movement comprising several control systems and several mobile dials, without multiplying the number of kinematic chains. The multiplication of the number of kinematic chains has as a corollary, the multiplication of the clock components used, the increase of the necessary volume, the increase of the energy losses related to friction and the reduction of the power reserve.
    SUMMARY DESCRIPTION OF THE DRAWINGS
    The present invention and its advantages will be better understood with reference to the appended figures and to the detailed description of a particular embodiment, in which: FIG. 1 is a back view of a part of a watch movement according to the present invention; and FIG. 2 is a front view of the movement illustrated in FIG. 1.
    MANNER OF REALIZING THE INVENTION
    The present invention is illustrated by FIGS. 1 and 2 in an embodiment in which a timepiece movement comprises two control systems and two mobile dials. Each mobile dial is linked to a regulating system. In return, and contrary to what is illustrated by FIGS. 1 and 2, each regulating system is not necessarily linked to a mobile dial. There can thus be two control systems and a single mobile dial, for example.
    As will be clear to those skilled in the art, it is of course possible to make a timepiece movement according to the invention, comprising a single regulating system and a single mobile dial.
    Figs. 1 and 2 illustrate an embodiment of a movement for a timepiece according to the present invention. This movement comprises a first kinematic chain 11 comprising a cylinder 12 which engrains with a center pinion (not shown) of a center mobile. This center pinion is secured to a center wheel 9 which engages with a first torque stabilizer 13. This torque stabilizer is formed of a wheel 14 and a torque stabilizer pinion. These two elements are capable of pivoting about the same axis 15, the wheel 14 being mounted idly on this axis. The pinion is secured to an inner disk 16 and engrains with the center wheel 9. The inner disk 16 further comprises two pivots 18 whose function is explained below. The inner disk 16 is integral with a spiral spring 19 in charge of transmitting the torque of the pinion to the wheel 14. This spiral spring 19 can be fixed by one of its ends to the inner disk 16, for example by means of the One of the pivots 18. The spiral spring 19 is furthermore fixed to the wheel 14 so that the wheel and the inner disk 16 are kinematically connected to one another by means of the spiral spring 19.
    The wheel 14 of the first torque stabilizer 13 comprises a transverse arm 20 disposed substantially along a diameter of this wheel. The pivots 18 of the torque stabilizer are arranged such that they exceed the transverse arm 20 in height. In this way, the pivots 18 act as a limiting member of the stroke of the inner disk 16 with respect to the wheel 14. This stroke limiting function makes it possible to prevent the breaking of parts, in particular of the spiral spring. 19, in the case of a race too important. The function of limitation of the pivots 18 is also useful to prevent the spiral 19 from winding or unrolling completely, its turns are in contact with each other and so it has more elastic properties. The pivots 18 also facilitate the adjustment of the angular displacement of the inner disk 16. Indeed, after an ideal setting, the pivots should undergo angular displacement as large as possible, without however resisting against the transverse arm. The adjustment of the movement of the inner disk 16 relative to the wheel 14 can be done initially by selecting a spiral spring 19 adapted. In a second step, this adjustment can be done by means of a movable peg holder if such a peg carrier is provided, or by moving a ferrule in which is fixed the spiral spring 19.
    The wheel 14 of the first torque stabilizer 13 engrains with a first intermediate mobile 21. This first intermediate mobile 21 engrains with a second intermediate mobile 22 which in turn engrains with a pinion (not shown) of a first regulating system 23, illustrated here in the form of a vortex.
    The first regulating system 23 of the first kinematic chain 11 is of the tourbillon type and comprises a Swiss lever escapement, this exhaust being formed of an escape wheel 24 and an exhaust pinion 25. This first regulating system 23 further comprises an anchor 26 and a balance-spiral27 cooperating with the anchor 26 so as to adjust its displacement. The anchor and the exhaust are mounted on a rotating cage 28 integral and coaxial with a mobile which can be a wheel of seconds. As in a conventional vortex, according to an advantageous embodiment, the exhaust performs a complete rotation in one minute.
    The first regulating system 23 comprises a ring gear 29 secured to rotating lacing 28. This ring gear 29 engrains with a first mobile dial 30. In the illustrated embodiment, this first mobile dial 30 is coaxial with the center wheel 9 and forms an upper dial.
    In the illustrated embodiment, the movement 10 according to the invention comprises a second kinematic chain 40. The second kinematic chain is similar to the first kinematic chain 11 and includes a torque stabilizer 41 engraine with the center wheel 9 This second torque stabilizer is identical to the first torque stabilizer.
    The second torque stabilizer 41 engrains with a third intermediate mobile 42 which is identical to the first and second intermediate mobile 21,22 of the first kinematic chain 11. This third intermediate mobile 42 engraine with a pinion of a second regulating system 43. As for the first regulating system, this second regulating system 43 is illustrated here in the form of a vortex.
    The vortex forming part of the second kinematic chain 40 comprises, just like the vortex of the first kinematic chain, a Swiss lever escapement, this escapement being formed of an escape wheel 44 and a pinion gear. Exhaust 45. This second regulating system 43 further comprises an anchor 46 and a balance spring 47 cooperating with the anchor 46 so as to adjust its displacement. The anchor and the exhaust are mounted on a rotating cage 48 integral and coaxial with a mobile which can be a wheel of seconds. As in a conventional vortex, according to an advantageous embodiment, the escapement can also perform a complete rotation in one minute.
    The second regulating system 43 also comprises a ring gear 49 integral with the rotary cage 48, the ring gear 49 engraining with a second mobile dial 50. In the illustrated embodiment, the second mobile dial 50 is coaxial with the wheel center 9, just like the first mobile dial.
    The second mobile dial 50 is placed below the first mobile dial 30. This first mobile dial 30, or upper dial, comprises at least one transparent or translucent zone 31, which allows to see at least partially, the second dial 50 or lower dial. The transparent area of the upper dial may be formed of a

    opening or through hole. It can also be formed of a transparent or translucent material. Some areas may be opaque to hide certain images or portions of images on the lower dial. It is possible to provide an upper translucent, partially transparent or translucent and partially opaque dial, for example to hide or to form images, depending on the desired effect. It is also possible to provide structures on the different dials, so as to create aesthetic effects such as for example moiré effects. In a movement as illustrated, comprising two kinematic chains each having a regulating system, each of the kinematic chains advantageously comprises a torque stabilizer. These torque stabilizers are designed to handle the small differences in the frequency of rotation of the two control systems. In an embodiment in which only one regulating system is provided, such a torque stabilizer is not necessary. It can be either deleted, which of course reverses the direction of rotation of the regulating system, or replaced by a gear assembly - conventional gear. In such an assembly, the pinion is secured to the wheel. As mentioned above, the movement 10 according to the invention could contain only one kinematic chain with a single mobile dial. In this case, any of the two kinematic chains described above could be deleted. According to different embodiments, the lower dial 50 may be fixed and the upper dial 30 movable; the upper dial can be fixed and the lower mobile dial or both dials can be mobile. The lower dial can display images, texts and / or any other visual indication, so as to provide information and / or an aesthetic effect. Depending on the number of components between the barrel and the dial and according to the respective dimensions of these components, it is possible to rotate the dials independently in the same direction of rotation or in opposite directions of rotation, at similar or different rotational speeds. The present invention is not limited to the embodiment described and illustrated, but extends to any variant or modification obvious to the skilled person. In particular, the movement according to the present invention can have a single regulating system or more than one. These control systems can be of the tourbillon or carousel type. In the case where the movement comprises more than one regulating system, these do not necessarily have to be identical or of the same type. If the movement has more than one regulating system, each of them does not necessarily lead to a mobile dial. It is for example possible to provide a movement comprising two or three control systems, in which only one of these control systems drives a mobile dial. It is also possible to provide a regulating system drives a mobile dial, the movement further comprising another mobile dial driven for example by a barrel and not by a regulating system. According to a variant, it is possible that the movement according to the invention comprises two control systems, these two control systems resulting in the same mobile dial. claims
