    BRIEF DESCRIPTION OF THE DRAWINGS [0020] Other details of the invention will appear more clearly on reading the description which follows, made with reference to the appended drawing in which:
    Fig. 1 is a fragmentary isometric view of a timepiece module according to the present invention, in which the device for rotating a mobile is represented,
    Fig. 2 shows in section the kinematic chain of the device for rotating the mobile according to FIG. 1
    Figs. Figures 3 to 6 show partial top views of the module of the present invention, in which a mobile locking and indexing mechanism is shown in different positions of use.
    Embodiment of the invention The present invention advantageously proposes a module M for a timepiece comprising a plate P adapted to be attached to a watch movement in order to provide a said timepiece with an additional function to those provided by the watch movement itself, including a separate function independent of the movement of the watch movement. In the context of the invention and the embodiment presented here, the additional function provided by the module is a decorative and playful display function according to which a display element in the dial of the timepiece is moved into the dial under an action of a user without consuming energy from the mainspring of the watch movement.
    The plate P supports according to the preferred embodiment of the invention a mobile 7 rotatably mounted on the plate about an axis ZZ 'substantially perpendicular to an upper plane of the plate P. This mobile 7 advantageously constitutes the output of the module, in connection with the display element to be mobilized, not shown. In the example shown, said axis of rotation Z-Z 'substantially passes through the center of said plate P, although this is not an essential feature of the invention. Thus the position of the axis of rotation Z-Z 'of the mobile can be arbitrary on the plate P, according to the particular needs.
    The module M of the invention further comprises a mechanism for rotating said mobile 7 about its axis Z-Z 'independent of a motor member of a watch movement. This rotation mechanism comprises firstly an actuating device 1, consisting for example of a pusher 11 cooperating with a rack 2 pivotally mounted about an axis 22 on the plate P, said rack being formed of a rake 21 meshing with a unidirectional torque transmission train comprising a first ratchet wheel 4 and a friction wheel 5.
    In the example shown, the pusher 11 is movably mounted in translation along an axis materialized by a radial rod R with respect to the plate P. Where appropriate, the stem R can be the winding stem of a watch movement. mechanics on which the module M is associated. In this case, the carriage can in particular be integrated with the winding crown integral with the winding stem to have a push function additional to the conventional winding / adjustment function.
    The pusher 11 is composed of a carriage having a ring 11 has threaded on the radial shaft R, which if it is not the winding stem of a watch movement is then itself is fixed in a blind hole O of the plate P. The carriage further comprises an arm 11b of connection to the rack 2. This arm is secured to a first end of the guide ring 11a and at its opposite end has a pin 11c driven on the arm 11b, said pin 14 extending through an oblong orifice 23 pierced in the rake 21 and thus achieving a sliding connection between the pusher 11 and the rack 2, so that a translational movement of the pusher 11 along the rod R causes a rotation of the rake 21 about its axis 22 and the transmission of a driving torque to an intermediate gear also engaged with the ratchet wheel 4 as will be described later.
    Finally, the pusher 11 is fixed integrally on the plate P by means of a stirrup 12 screwed on the plate P, said stirrup 12 being arranged such that a sliding slot of the arm 11b of the carriage is formed between the surface of the plate P and an upper plate of the stirrup 12 so as to maintain said arm 11b in a plane parallel to the upper surface of the plate and the axis of the rod R. Finally, as shown in FIG. 1, the guide of the carriage following the rod R is ensured by guide and stabilizing studs 11 d parallel to the rod R arranged between the stirrup 12 and the carriage of the pusher 11.
    It should be noted that although in the example shown the pusher 11 is movable in translation relative to the plate could also be considered to achieve a mobile pusher in rotation on the plate and operable from the periphery thereof , in particular integral or coupled by any appropriate means to the rack 2.
    At the level of the unidirectional torque transmission gear the first ratchet wheel 4 and the friction wheel 5 are both rotatable about a proper axis, respectively 44 and 51 on the plate P and engaged the one with the other by a peripheral toothing. In practice, the ratchet wheel 4 is of the internal snap type, that is to say composed of a lower wheel 41 and an upper wheel 42 between which pawls 43 engage, alternately declicking in a wheel or in the other following the direction of rotation. Thus each of the lower wheels 41 and upper 42 has a clean peripheral toothing, respectively 41d, 42d.
    Preferably, the rake 21 is coupled to the unidirectional torque transmission train via the intermediate gear 3 to prevent any locking effect in the torque transmission of the rake 21 to the ratchet wheel 4. As this is more simply visible in FIG. 2, the intermediate gear 3 meshes with the toothing 41 d of the lower wheel 41 and the upper wheel 42 meshes with its teeth 42d with the peripheral toothing 5d of the friction wheel 5.
    In addition, the friction wheel 5 supports on its axis 51 an output gear 6 meshing by a peripheral toothing 6d with a peripheral toothing 7d of the mobile 7 to drive as shown in FIG. 2. Preferably, the teeth 6d and 7d of the output gear 6 and the mobile 7 are shaped so as to be able to drive the mobile 7 in a clockwise rotational movement and block a rotation in the counterclockwise direction.
    By the configuration described above the actuating device 1 allows a user, by a pressure applied to the pusher 11, to transmit via the rake 21 and the unidirectional transmission train a driving torque adapted to rotate the mobile 7 about its axis ZZ 'in one direction, in this case a clockwise direction of rotation. A plurality of successive presses on the pusher 11 also makes it possible to print an acceleration to the mobile 7 according to the particular desire of the user.
    Although the module M of the present invention could without operating in its previously described form and fulfill its function of perfectly rotating the mobile 7 it is also advantageous to associate an additional locking mechanism and indexing said mobile 7 to provide an additional level of control over the rotation of the mobile 7, and in particular to prevent undesired unwanted rotation of the mobile 7. Such locking mechanism and indexing is represented in its different main operating positions in fig. 3 to 6.
    According to the embodiment shown in FIGS. 3 to 6, the locking mechanism comprises in the first place a rocker 10 comprising at a first end, said locking, a hook 101 for locking the mobile 7 about the axis Z-Z ', said hook being shaped to cooperate, as shown in FIGS. 3 and 6, with a notch 71 formed in a bearing 72 of the mobile 7. Thus, when the hook 101 is inserted into the notch 71 of the mobile 7 it is locked in rotation about the axis ZZ 'in at least one angular position, an action is exerted on the pusher 11 or not on the part of a user.
    The latch 10 is movably mounted on the plate P about an axis 103 near a second end, said actuating, having a bearing surface 102 on which the rocker 10 can be pivoted so as to extract the hook 101 of the notch 71 of the bearing 72.
    In order to secure the engagement of the hook 101 in the notch 71 even in the event of shocks or vibrations for example, the hook 101 is elastically held in abutment against the bearing 72, in particular the peripheral surface thereof, by means of a leaf spring 12 fixed on the plate. To mobilize the rocker 10 in rotation and to release the mobile 7 in rotation on its axis Z-Z ', the blocking and indexing device of the module M comprises a device for releasing the rocker arranged to exert a pressure force greater than the restoring force of the leaf spring 12 on the bearing surface 102 of the rocker so as to release the hook 101 from the notch 71.
    This release device comprises in the example shown a latch 9 formed by a substantially plane annular sector 92 rotatably mounted around the axis ZZ 'on the plate P between a starting position (FIG. a release position of the hook 101 of the rocker 10 (FIG 4). Said latch 9 comprises a central groove 921 forming a circular arc-shaped slide centered on the axis Z-Z ', in which are inserted in two separate angular positions and two screws 922 forming fixed slides on the plate P. Thus the latch 9 can slide between its starting position and its arrival position guided by the screws on the plate and the groove.
    On an external lateral field of the lock 9 is a push bolt 91 for a user to mobilize the lock between said starting positions and arrival. In addition, on an internal lateral field towards the center of the plate P, the latch 9 further comprises at least, in this case two, pawls or hooks 94 secured to the latch 9. These hooks 94 form actuating members arranged to engage, during a rotation of the latch 9 from its starting position to its release position, a thrust member on the bearing surface 102 of the rocker 10. The thrust member is rotatably mounted on the plate P and has a cam 111 and a star 112 superimposed on said cam 111 and rotationally integral therewith. Advantageously, the cam 11 and the star 112 forming the thrust member 11 are configured and arranged on the plate P so that the pawls or hooks 94 of the latch 9 engage, during a push of the user on the bolt 91 to move the latch 9 from the starting position to the release position of said latch 9 a tooth of the star 112. The thrust member then pivots on itself and a peripheral cam surface of the cam 111, configured to bear on the scope 102 of the rocker 10 on a given angular stroke then causes the pivoting of the rocker 10 and the release of the hook 101. To prevent any rotation of the push member not caused by the hooks 94 said thrust member is held in angular position by a jumper fixed on the plate P.
    The latch 9 finally has on its internal side field a rack 93. This rack 93 is in direct contact with a first gear of a second ratchet wheel 8 identical to the first ratchet wheel 4, that is to say said having a lower wheel having a first toothing and an upper wheel having a second toothing, a ratchet mechanism being housed between the two lower and upper wheels. The second ratchet wheel 8 is coupled by the toothing of the lower wheel to the rack 93 and by the toothing of the upper wheel with the friction wheel 5. The friction wheel 5 is therefore coupled simultaneously in the module of the invention. the rotation device and the latch 9.
    The blocking and indexing mechanism of the module M of the invention is implemented as follows.
    In a starting position, corresponding to a locking position of the mobile 7 and shown in FIG. 3, the latch 9 is in the low position and the hook 101 inserted in the notch 71 of the bearing 72 of the mobile 7. The latch 9 is held resiliently by a spring 14 fixed on the plate P and having two wolf teeth 141 cooperating with an analogous wolf tooth 95 formed on the internal field of the annular sector forming the latch 9, so as to prevent unwanted rotation of the latch 9.
    To release said mobile 7, a user then exerts a push on the bolt 91 in the clockwise direction as shown by the arrow F in FIG. 4, so as to push the latch 9 to its release position. This displacement of the lock 9 causes, on the one hand, the unlocking of the lock 9 at the level of the wolf teeth 95, 131 for under the thrust force greater than the return force of the spring 13. On the other hand, the hooks 94 engage then on the teeth of the star 112 which pivots, as the cam 111 which then pushes the scope 102 of the rocker 10, rotating it and thus releasing the hook 101 of the notch 71. The user can then put the mobile 7 in rotation by actuating via the pusher 11 the rotation device of FIGS. 1 and 2. Finally, when the latch 9 is mounted, the latch 9 rotates the lower wheel 81 of the second ratchet wheel 8 via the rack 93, without the upper wheel 82 being moved by the clutch release action and friction wheel friction 5.
    The rotation of the mobile 7 about its axis 7 involves the rotation of the friction wheel 5 carrying the output gear 6 in engagement with the mobile 7, said friction wheel 5 is also in engagement with the second ratchet wheel 8 by the toothing of the upper wheel. By the set of pawls of this second ratchet wheel 8 the upper wheel then rotates the lower wheel in a counterclockwise direction and, therefore, the descent and return of the latch 9 to its starting position due to the kinematic connection between the lower wheel and the rack 93 of the lock.
    When the user finally pushes the latch 9 at the end of the stroke to its extreme high position, as shown in FIG. 6, this allows it to bring the mobile 7 in the locking position by falling from the hook 101 in the notch 71. Indeed, the rack 93 driving the ratchet wheel 8 in engagement with the wheel and friction 5 then rotates also the pinion 6 and the mobile 7 until the notch 71 is in front of the hook 101.
    If the locking does not occur when the latch 9 is in the extreme position then it is possible to bring it back to its starting position without moving the mobile by the friction of the wheel 5 and the disengagement of the wheel ratchet 8, until the wolf tooth 95 encounters the first wolf tooth 141.
    The user can then push the lock upwards to rotate the mobile 7 to its locking position. He can then return the lock 9 to its starting position secured by the teeth of wolf 141.
    The module M of the invention thus makes it possible to integrate in a timepiece a mechanical module independent of the watch movement and consuming no energy thereof and by providing additional display functionality and / or interaction with the timepiece for users.
