    Description
    Technical Field [0001] The present invention relates to a watch movement comprising a frame intended to be assembled to a timepiece box and a turntable movable in rotation with reference to the frame and bearing at least one horological complication.
    The present invention also relates to a timepiece provided with a te! watch movement.
    For horological complication within the meaning of the present invention, we must understand the meaning generally accepted today, that is to say, any watchmaking mechanism for a purpose other than the display of the current time. As non-limiting examples, mention may be made of sound production mechanisms such as ringtones or musical mechanisms, chronograph mechanisms, mechanisms for displaying information other than the current time, etc.
    State of the art [0004] Timepieces in which a particular clockwork mechanism defining a complication is embedded on a rotary support are already known according to different approaches.
    Thus, for example, the company Watches Breguet SA sells a timepiece corresponding to the teaching of the patent application EP 1 708 048 A1, that is to say whose movement comprises two mounted vortexes rotating on a turntable with reference to a fixed frame in the box, at a rate of one revolution every twelve hours, a fixed bridge of the rotating plate serving as a display member of the current hours.
    [0006] Manufacture of watch movements of self-winding type are also known in which the winding mass, madly mounted on its shaft, carries one or more complications such as for example a mechanism for displaying the power reserve.
    Thus, these mechanisms of the state of the art do not require the implementation of locking means of the rotating support.
    Disclosure of the invention [0008] A main object of the present invention is to propose a watchmaking movement of alternative construction to known constructions, making it possible to produce a timepiece comprising a horological complication embedded on a rotating support whose rotation can be controlled.
    For this purpose, the present invention relates more particularly to a watch movement of the type mentioned above, characterized in that it comprises a probe mounted movably on the plate and cooperating with a fixed cam of the frame.
    Thanks to these characteristics, the animation provided by the watch movement is not permanent and the wearer of the timepiece is free to decide the moments he will wish to enjoy.
    According to a non-limiting preferred embodiment which will be described in detail below, the rotating support, which is a plate, carries a musical mechanism. A spectacular effect is then obtained when the musical mechanism is actuated since not only the rotary member of the mechanism rotates on itself, in a conventional manner, but also all the rest of the musical mechanism rotates, because of the rotation of the plate rotating, preferably along an axis of rotation distinct from that of its rotary member. In addition, the fact that the entire musical mechanism is rotated, and therefore in particular its keyboard, makes it possible to vary the direction of emission of the sound waves and therefore to tend to uniformize their propagation towards the outside of the box. the corresponding timepiece.
    Other features and preferred embodiments of the present invention are the subject of the dependent claims.
    The present invention also relates to a timepiece equipped with a watch movement that meets the characteristics that have just been stated.
    BRIEF DESCRIPTION OF THE DRAWINGS [0014] Other features and advantages of the present invention will become more apparent upon reading the detailed description of a preferred embodiment which follows, with reference to the accompanying drawings given by way of non-limiting example. in which: FIG. 1 shows a simplified front view of a watch movement according to a preferred embodiment of the present invention; fig. 2 represents a simplified front view of a part of the watch movement of FIG. 1 in a first configuration; fig. 3 represents a simplified front view of a part of the watch movement of FIG. 1 in a second configuration; fig. 4 represents a simplified front view of a part of the watch movement of FIG. 1 in a third configuration; fig. 5 is a simplified front view of a part of the watch movement of FIG. 1 in a fourth configuration; fig. 6 shows a simplified front view of a construction detail of the watch movement of FIG. 1 in the first configuration; fig. 7 is a simplified front view of the constructional detail of FIG. 6 in the second configuration.
    Embodiment (s) of the Invention [0015] FIG. 1 represents a simplified front view of a watch movement 1 comprising a complication embedded on a support rotating on demand according to a preferred embodiment of the present invention. The watch movement 1 is illustrated by way of non-limiting illustration. In particular, this watch movement 1 comprises certain clock mechanisms that are not necessarily related to the implementation of the present invention. Also, for the sake of brevity and clarity, only the elements contributing to the implementation of the invention and / or to better understand the construction and operation will be described in detail.
    The watch movement 1 comprises a frame 2 intended to allow the assembly of the movement in a watch case (schematized in FIG 2, with the reference numeral 4). The frame 2 carries a turntable 6, the latter being connected to the frame 2 by any suitable known means allowing a relative rotational movement between them, such as for example a ball bearing (not shown), the axis of rotation of the turntable being here confused with the central axis of the watch movement 1, without limitation.
    The watch movement 1 comprises a watch mechanism 8, known to those skilled in the art, intended to support a display dial of the current time by maintaining it in a constant angular orientation with reference to the box of the piece regardless of the angular orientation of the turntable 6. In addition, the watch mechanism 8 is typically arranged to control the display needle positions taking into account the angular orientation of the turntable 6. This clock mechanism 8 does not have a direct link with the implementation of the invention and being of known construction, it will not be further described here.
    [0018] Moreover, the watch movement 1 comprises watch mechanisms related to the measurement of time and to the display of the current time, which will not be described in detail, in particular a time base comprising a three-dimensional tourbillon. axial 10.
    To come more directly to the invention now, the turntable 6 carries a horological complication, here a musical mechanism for illustrative non-limiting whose components are distributed in different locations of the turntable 6.
    In a nonlimiting manner, the musical mechanism here comprises two rotary members 12 each of which has the shape of a roller associated with a keyboard 14. In a conventional manner, each roller 12 carries pins 16 (all not shown) intended for cooperate with blades 18 of the keyboard 14 corresponding to emit sounds and produce a musical melody when the roller 12 is driven to turn on itself.
    The rotational drive of the rollers 12 is made from a source of mechanical energy, here a cylinder 20 housing a barrel spring in a conventional manner, as best shown in FIG. 2.
    The drive of the rollers 12 from the barrel 20 is however carried out indirectly. Indeed, the toothed drum of the barrel 20 is kinematically connected to a toothed gear 22 for driving the turntable 6, in particular via a locking wheel 24 and a speed regulator 26 (FIG. ) with conventional variable inertia. As will be seen below, the locking mobile 24 may have a locked state in which it locks the barrel of the barrel 20, and thus the musical mechanism, and an unlocked state in which it leaves the barrel of the barrel 20 free to rotate. In the latter case, the toothed mobile 22 is rotated and rolls on a fixed toothing 28 carried by the frame 2, causing a rotational movement of the turntable 6 with reference to the frame 2, preferably at a constant speed under the effect of the action of the cruise control 26.
    Rotation of the rotating platen 6 is then used to drive the rollers 12 in rotation by means of another fixed toothing 30 carried by the frame 2. Each roller 12 is integral with a toothed pinion 32 (Fig. 1) arranged in engagement with an axial return 34, itself arranged in engagement with the fixed toothing 30. Consequently, when the turntable 6 pivots, the gear 34 rolls on the fixed toothing 30 and drives the pinion 32 in rotation, and therefore the corresponding roller 12.
    The musical mechanism illustrated and described here is of the type on demand, without limitation, that is to say, it is engaged in response to a predefined action of a user.
    A box 4 of a timepiece has been shown schematically in FIG. 2, which houses a pusher 38 intended to be actuated by a user to engage the musical mechanism and thus the visual animation of the workpiece due to the rotation of the turntable 6.
    Note in FIG. 2 that the turntable 6 carries three different latches 40, 42 and 44, each of which has an actuating portion arranged projecting from the periphery of the turntable 6 in order to cooperate with the pusher 38.
    These three flip-flops 40, 42 and 44 are arranged in such a way that an action on any one of them has the effect of actuating a single mechanism, namely a latch 46.
    The latch 46 is rotatably mounted on the turntable 6 and has a first nozzle 48 to be positioned or not in the passage of a finger 50 carried by the locking latch 24; to lock it or leave it free to turn.
    The latch 46 has a second spout 52 arranged to cooperate with the latch 40 and rotate the latch 46 in the anti-clockwise rotation in the view of FIG. 2, in response to a pressure on the latch 40, that is to say to move it from a locking position to an unlocking position.
    The latch 46 has a third spout 54 arranged to cooperate with a return 56 rotatably mounted on the turntable 6, the return 56 being itself arranged to rotate in the clockwise direction in FIG. 2 in response to a pressure on the rocker 42. It also emerges from FIG. 2 that a rotation of the reference 56 in the clockwise direction causes a rotation of the latch 46 in the anticlockwise rotation direction, ie an unlocking of the musical mechanism.
    The latch 44 is arranged on the turntable 6 so that a pressure on it causes its rotation in the anti-clockwise rotation in FIG. 2, which causes a rotation of the rocker 42, and consequently of the return 56, in the clockwise direction.
    FIG. 2 illustrates the watch movement 1 in a first configuration in which the musical mechanism has a locked state, the rocker 40 being located opposite the pusher 38.
    It should be noted that different springs are provided, but not shown, to tend to maintain the latches 40, 42 and 44 in their rest position as illustrated in FIG. 2.
    A pressure on the pusher 38 to unlock the musical mechanism, which causes a rotation of the turntable 6 in the clockwise direction in the view of the figures, as is apparent from the view of FIG. 3 illustrating the watch movement 1 in a second configuration.
    When, in the present case, the turntable 6 has rotated 120 ° since the initial state of FIG. 2, as shown in FIG. 4, latch 46 resumes its locking position, as will be explained later. The latch 42 is then located opposite the pusher 38 and the turntable 6 stops its rotation. A new pressure on the pusher 38 causes a new unlocking via the rocker 42 which acts on the return 56 which itself acts on the latch 46 to turn the latch in the anti-clockwise direction of rotation and place it substantially in the position shown in fig. 4.
    The turntable 6 then resumes its rotation for 120 °, that is to say until the latch 44 is located opposite the pusher 38, as shown in FIG. 5.
    A new pressure on the pusher 38 from this configuration causes a new rotation of the turntable 6 to replace the watch movement 1 in the configuration of FIG. 2.
    It appears from figs. 2 to 5 that the latch 46 has an additional arm 58 carrying a finger 60 arranged projecting from the side of the turntable 6.
    Figs. 6 and 7 provide a better understanding of how the musical mechanism can be controlled to rotate 120 ° each time the pusher 38 is pressed.
    The frame 2 carries a ring 62, close to its periphery, in which there are three internal notches 64, distributed in such a way that two adjacent notches are located at 120 ° from one another.
    The configuration of the watch movement 1 in FIG. 6 corresponds to that illustrated in FIG. 2, the finger 60 carried by the latch 46 having been represented in a first notch 64.
    As a result of pressure on the pusher 38, the latch 46 pivots and releases the turntable 6 which starts to rotate to lead to the configuration of FIG. 3 which is reproduced in FIG. 7.
    It is noted in FIG. 7 that the ring 62 plays the role of a cam: the finger 60 is no longer located opposite one of the notches 64, the latch 46 is retained in its unlocked position as shown in FIG. 3 and the rotation of the turntable 6 continues to the configuration illustrated in FIG. 4. In this configuration, the finger 60 having traveled 120 ° is opposite the next notch 64 and the latch 46 can resume its locking position under the effect of the action of its return spring (conventional , not shown). The locking wheel 24 is then again immobilized, as is the turntable 6, and the music produced by the action of the pins 16 on the blades 18 ceases.
    It is understood from the above description that the watch movement 1 with a musical mechanism according to the present invention gives a dynamism, both visual and sound, more important to the corresponding timepiece than the pieces of the prior art. mentioned above because of the rotational movement of the turntable 6.
    A watch movement and a corresponding timepiece are thus obtained by implementing the present invention, whose visual and sound properties are novel and exceptional.
    The foregoing description attempts to describe a particular embodiment by way of non-limiting illustration and the invention is not limited to the implementation of certain particular features which have just been described. as for example the nature of the horological complication illustrated and described or the number of sets rotary body - keyboard as it has been illustrated and described. Moreover, the two sets are arranged to operate synchronously in the preferred embodiment which has been described in a non-limiting manner, but the skilled person can adapt the present teaching according to his own needs, without any difficulty and therefore, without departing from the scope of the present invention. Thus, it may in particular provide for example that the two sets operate alternately.
    Furthermore, the angle of 120 ° is indicative and may be modified without departing from the scope of the invention, the number of actuating flip-flops not necessarily being equal to three. A single rocker is of course conceivable, as well as two, four, five, six, even ten, etc.
    It is also possible that the musical mechanism stops working on demand rather than having traveled a predefined angle, without departing from the scope of the invention.
