Description

Technical field

[0001] The present invention relates to a device for actuating a watch mechanism, for a watch movement, comprising – a control member, – a shuttle capable of being moved from a first position to a second position in response to a suitable action by a user on the control member, – an elastic return member arranged to exert a return force on the shuttle and tend to position it in its first position, – an actuating member, intended to be mounted movably on a frame element of the watch movement, between a rest position and an actuating position, and to have a kinematic connection with a mobile of the watch mechanism, the actuating member being capable of being moved towards its actuating position by the shuttle, and towards its rest position by the watch movement or the watch mechanism.

[0002] The invention also relates to a watch movement comprising such an actuating device, as well as a timepiece comprising such a watch movement.

State of the art

[0003] Various devices for actuating similar watch mechanisms are already known in the state of the art, in particular in relation to animation or striking mechanisms.

[0004] In general, timepieces comprising a striking mechanism comprise an external control member of the target type, sliding along the caseband to wind and actuate the striking mechanism.

[0005] By way of illustration, patent application CH 709151 A2 describes a winding and actuating device associated with a minute repeater mechanism of similar construction. More specifically, this winding and actuating device comprises a pusher capable of acting on an actuating lever of the minute repeater mechanism, following a mode of action similar to that of a bolt. This device is arranged in such a way that the minute repeater mechanism can be triggered as soon as the winding of a barrel spring ensuring its operation is complete and, this, independently of the position of the pusher, that is to say even when the user does not release it. To this end, the actuating lever acts on a winding lever of a striking barrel by means of a transmission lever on which the winding lever is pivotally mounted. The transmission lever also carries a rotating shuttle acting as a pawl, this shuttle being held, by an elastic return member, in a first position with reference to the transmission lever, in which it maintains the relative orientation of the fixed winding lever with reference to the transmission lever, as long as the barrel spring is not fully charged. Furthermore, the shuttle is capable of cooperating with a fixed pin intended to rotate it relative to the transmission lever when the latter continues to pivot, to make the shuttle take a second position in which it releases the winding lever to allow the minute repeater to be triggered.

[0006] Other similar timepieces are known in which the winding and actuation of a striking mechanism is achieved by rotation of an external control crown.

[0007] As an example, patent EP 3032356 B1 describes such a timepiece in which the actuating device comprises a lock of the striking mechanism arranged to be able to be neutralized once the striking barrel is sufficiently charged following rotation of the external control crown by a user.

[0008] It will be noted that in the case of the two constructions which have just been presented, the striking mechanism is triggered as soon as the striking barrel spring has received a predefined quantity of mechanical energy, in other words after a predefined (constant) stroke of the corresponding external control member, whether or not the user continues to apply tension to the latter.

[0009] Thus, it may be useful to propose an actuation device which can in particular be implemented both in relation to a timepiece mechanism whose operation is likely to be triggered when a predefined constant quantity of mechanical energy is supplied to it, and in relation to a timepiece mechanism whose operation is likely to be triggered when it has received a sufficient quantity of mechanical energy to ensure its operation at the time of actuation, in other words which is likely to operate with a variable load adapted at each instant to its needs.

Disclosure of the invention

[0010] A main aim of the present invention is to propose an actuating device for a watch movement of alternative construction to the constructions known from the prior art, making it possible in particular to actuate various watch mechanisms, whether they are of the constant winding or variable winding type.

[0011] For this purpose, the present invention relates more particularly to an actuating device of the type mentioned above, characterized in that it comprises a locking member capable of occupying a first state, of locking, in which it makes the shuttle integral with the control member to allow its movement towards its second position, a second state, neutral, in which it leaves the shuttle free to move towards its first position under the effect of the action of the elastic return member and independently of the control member, and by the fact that the locking member is arranged to pass from its neutral state to its locking state when the shuttle or the actuating member is returned to its first position.

[0012] Thanks to these characteristics, it is possible to implement a large number of variant embodiments of the actuation device according to the present invention, in particular to take into account the needs defined by a given timepiece mechanism. Thus, it is for example possible to associate the actuation device according to the invention with a timepiece mechanism of the variable winding type or with a timepiece mechanism of the constant winding type, and to provide for triggering of the timepiece mechanism when its winding is sufficient or when the user releases the external control member associated with the actuation device.

[0013] According to a preferred embodiment, it can be provided that the locking member comprises a slider arranged on the shuttle in such a way that the slider and the shuttle are capable of exhibiting a relative movement to cause the locking member to pass from one state to the other.

[0014] It is then possible to provide that the shuttle and the slide are arranged in such a way that the shuttle is capable of moving the actuating member by means of the slide.

[0015] Thus, the return of the actuating member to its first, resting, position is conditioned by the movement of the slide in the same direction, which implies that the triggering of the clockwork mechanism associated with the actuating device only occurs at the exact moment when the user releases the control member.

[0016] It is advantageous to provide that the shuttle carries a support surface capable of cooperating with a stop of the slide when it is moved to its second position to maintain the locking member in its locked state.

[0017] Generally, it can be provided that the control member comprises a toothed crown arranged to cooperate with at least one tooth carried by the shuttle.

[0018] In this case, it is further possible to provide that the shuttle carries a toothed pinion whose teeth are arranged to mesh with the toothed crown, that the teeth of the toothed pinion define the bearing surface, and that the stop of the slide is arranged to bear against the toothed pinion in the locking state of the locking member, so as to lock the rotation of the toothed pinion on itself.

[0019] Thanks to these features, when the shuttle moves towards its first position, under the effect of the action of its elastic return member, the toothed pinion can disengage from the stop of the slide, by passing from the locking configuration to the free configuration, and the toothed pinion thus becomes free to roll on the teeth of the control member which can remain stationary. Thus, the external control member for actuating the control member is not driven when the shuttle returns to its first position.

[0020] Furthermore, it is advantageous to provide that the actuating member comprises a winding lever carrying a finger arranged inside a cavity formed in the slide in such a way that the finger is capable of cooperating with at least one side wall of the cavity when the shuttle is moved to its second position.

[0021] Thus, the finger is advantageously capable of cooperating with the wall of the cavity of the slide when the arming lever is returned to its rest position, to ensure a return of the locking member to its locked state.

[0022] In this case, it is still preferable to provide that the device comprises a spring arranged so as to tend to position the slide with reference to the shuttle in such a way that the locking member is in its locked state when the shuttle is in its first position. It is more particularly possible to provide that the spring is integral with the winding lever, by being arranged to cooperate with a pin carried by the slide. Such a characteristic is for example particularly advantageous in the case where the timepiece mechanism is a striking mechanism whose triggering is directly linked not to a constant stroke of an external control member, but to the charge level of its striking barrel which must then be sufficient to strike the hour corresponding to the instant of actuation. In this case, in fact, the spring makes it possible to ensure an effective return to the locked state after the end of the striking.

[0023] In general, the present invention also relates to a watch movement comprising an actuating device meeting the preceding characteristics, associated with a watch mechanism comprising a striking mechanism or an animation mechanism, the winding lever being arranged in engagement with an actuating lever of the striking mechanism or of the animation mechanism.

[0024] The present invention also relates to a timepiece comprising a watch movement according to the above characteristics.

[0025] According to a preferred non-limiting variant embodiment, the present invention relates to such a timepiece comprising an external control crown having at least one axial actuation position in which it is capable of cooperating with the control member to actuate it in response to a rotation exerted by a user.

[0026] Other features and advantages of the present invention will become more clearly apparent upon reading the detailed description of a preferred embodiment which follows, made with reference to the appended drawings given as non-limiting examples and in which: – Figure 1a represents a simplified perspective view of a winding and actuating device according to a preferred embodiment of the invention, in a first configuration; – Figure 1b represents a simplified sectional view of a construction detail of the winding and actuating device of Figure 1a, in the first configuration; – Figure 2 represents a simplified perspective view of the winding and actuating device of Figure 1a in a second configuration; – Figure 3a represents a simplified perspective view of the winding and actuating device of Figure 1a in a third configuration; – Figure 3b represents the same simplified sectional view as that of Figure 1b, in the third configuration, and – Figures 4a, 4b and 4c represent the same simplified cross-sectional view, of a construction detail of a timepiece associated with the winding and actuating device of Figures 1a to 3b, according to a preferred embodiment, in three different respective configurations.

Method(s) of carrying out the invention

[0027] Figures 1a, 2 and 3a represent the same simplified perspective view of an actuating device 1 according to a preferred embodiment of the invention, in different first, second and third respective configurations, while Figures 1b and 3b represent the same sectional view of a construction detail of the device 1, respectively, in the first configuration and in the third configuration.

[0028] More specifically, the illustrated actuation device 1, which will be described below as a non-limiting illustrative example, may in particular be implemented in a timepiece comprising a striking mechanism and/or an animation mechanism (not shown), such as a minute repeater mechanism and/or an automaton for example. The present invention may however be implemented in relation to another type of suitable timepiece mechanism, without departing from the scope of the present invention as defined by the attached set of claims.

[0029] The actuating device 1 is intended to cooperate with an external control member of the corresponding timepiece. This external control member can take different forms without departing from the scope of the invention. According to the preferred embodiment illustrated and described, the external control member takes the form of an external control crown 2, the latter being capable of occupying at least one axial actuating position in which it actuates the actuating device 1 in response to a rotation exerted on it by a user. Of course, the external control member can take any other suitable form, such as for example a bolt.

[0030] The external control crown 2 is secured to a winding and time-setting stem 4 advantageously enabling the time to be set in a clock movement of the corresponding timepiece, and preferably arranged to be able to manually wind a mechanical energy source of the timepiece.

[0031] The external control crown 2 is arranged here so as to be able to drive a toothed control pinion 6 in rotation when it is in its axial actuating position.

[0032] The control pinion 6 cooperates with a control member of the device 1 comprising a toothed crown 8 rotatably mounted on a guide surface (not visible) preferably carried by, or arranged on, a peripheral frame element of the watch movement (not shown) or on a decorative element of the corresponding timepiece, in particular on its case, or even its caseband.

[0033] The toothed crown 8 is also in permanent engagement with a transmission pinion 10 rotatably mounted at a first end of a shuttle 12.

[0034] The shuttle 12 is advantageously guided, by guide means not shown, to be able to present a movement with reference to the toothed crown 8, following a trajectory located opposite the toothed crown 8 and at a substantially constant distance from the latter, that is to say in such a way that the transmission pinion 10 can remain in permanent engagement with the toothed crown 8. The trajectory of the shuttle 12 emerges particularly from a comparative examination of FIGS. 1a, 2 and 3a representing the position of the shuttle 12 in three different configurations, as will emerge from the explanations which follow. In particular, it will be noted that the shuttle 12 is advantageously arranged so as to be able to move between a first position, of rest (FIG. 1a), and a second position, of actuation (FIG. 2).

[0035] The shuttle 12 is secured to an elastic return member 14 by its second end, itself being secured to a fixed element of the corresponding timepiece (either the frame of the corresponding watch movement, or a decorative element such as the case for example) by means of a rigid base 16.

[0036] The elastic return member 14 comprises a central portion 18 elastically deformable from a rest state associated with the rest position of the shuttle 12, as illustrated in FIG. 1a, to a compressed state associated with the actuating position of the shuttle 12, as illustrated in FIG. 2. FIG. 3a illustrates an intermediate load state, in which the elastic return member 14 is restoring accumulated mechanical energy by returning from its compressed position to its rest position.

[0037] The device 1 further comprises a locking member capable of occupying a first, locking state, in which it makes the shuttle 12 rotationally integral with the toothed crown 8 to allow its movement towards its second position, and a second, neutral state, in which it leaves the shuttle 12 free to move towards its first position under the effect of the action of the elastic return member 14 and independently of the toothed crown 8.

[0038] According to the present preferred embodiment, the locking member advantageously comprises a slide 20, carried by the shuttle 12 while being arranged on it so as to be able to present a relative displacement in translation with respect to the latter, to define a locking state of the locking member (FIGS. 1a and 2) and a neutral state (FIG. 3a).

[0039] The slide 20 has a cavity 22 defining a housing for a finger 24 secured to an actuating member of the watch mechanism, comprising here, by way of non-limiting illustration, a winding lever 26 intended to be rotatably mounted on a frame element of the watch movement, such that a movement of the slide 20 with reference to the frame of the watch movement can cause a rotation of the winding lever 26 by cooperation between a side wall of the cavity 22 and the finger 24.

[0040] The winding lever 26 comprises a toothed sector arranged in engagement with an actuating lever 28 of the watch mechanism intended to be actuated by the actuating device 1, such that a rotation of the winding lever 26 can cause a rotation of the actuating lever 28 and therefore a winding and an actuation of the watch mechanism concerned in response to a rotation of the external control crown 2.

[0041] In the case of a striking mechanism, the rotation of the winding lever 26, and therefore of the actuating lever 28, can advantageously make it possible to charge a striking barrel, the striking mechanism then being triggered when the winding lever 26 is released to be able to move from its actuating position to its rest position.

[0042] The arming lever 26 further carries a spring 30, here made in one piece with the arming lever 26, arranged so as to be able to bear on a pin 32 carried by the slide 20.

[0043] An examination of Figure 1b (cross section along the longitudinal direction of the shuttle 12) shows that the transmission pinion 10 defines a bearing surface capable of cooperating with a portion of the slide 20 defining a stop 34 when the transmission pinion 10 moves to the left in the view of Figure 1b (or in the clockwise rotation direction in the view of Figure 1a, with reference to the center of the watch movement).

[0044] In the rest position illustrated in FIG. 1a, the angular orientation of the winding lever 26 is preferably defined by the clockwork mechanism associated with the device 1, while the spring 30 ensures that the shuttle 12 and the slide 20 are held in a relative position associated with the locking state of the locking member, in which the transmission pinion 10 bears against the stop 34 of the slide 20.

[0045] Preferably, it is provided that the external control crown 2 drives the control pinion 6 in only one direction of rotation (an exemplary embodiment allowing this will be described in relation to FIGS. 4a to 4c), here when it is turned in the clockwise direction of rotation (when it is observed from outside the timepiece).

[0046] Starting from the configuration illustrated in FIG. 1a, when the external control crown 2 is turned in the clockwise direction of rotation, it drives the control pinion 6 in rotation in the same direction (still from an observation point located outside the timepiece).

[0047] Rotation of the drive pinion 6 causes rotation of the toothed ring 8 in the clockwise direction of rotation in the view of FIG. 1a.

[0048] This movement of the toothed crown 8 should cause the transmission pinion 10 to rotate on itself in the clockwise direction of rotation in the view of FIG. 1a. However, the properties of the contact between the transmission pinion 10 and the stop 34 of the slide 20 prevent the transmission pinion 10 from rotating.

[0049] Thus, instead of rotating on itself, the transmission pinion 10 follows the movement of the toothed crown 8 and moves without pivoting in the clockwise direction of rotation in the view of FIG. 1, driving the shuttle 12 and the slide 20 in its movement.

[0050] Figure 2 illustrates the configuration of the actuating device 1 after a maximum displacement of the shuttle 12, in which it can be seen that the deformable central portion 18 of the elastic return member 14 is in its maximum compression state. The shuttle 12 and the arming lever 26 are then in their actuating position.

[0051] In the case of a striking mechanism, for example, the striking barrel is then loaded and ready to enable the striking mechanism to operate.

[0052] As long as the user keeps the external control ring 2 under tension, the device 1 remains in the configuration illustrated in FIG. 2, the elastic return member 14 then storing a maximum of mechanical energy.

[0053] When the user releases the external control crown 2, the toothed crown 8 becomes free to rotate in the counterclockwise direction of rotation in the view of FIG. 2, under the effect of the action of the elastic return member 14 on the shuttle 12, and therefore on the transmission pinion 10.

[0054] As soon as the transmission pinion 10 disengages from the stop 34 of the slide 20, it becomes free to rotate on itself. The shuttle 12 and the slide 20 thus pass into a position associated with the neutral state of the locking member.

[0055] The elastic return member 14 then pushes the shuttle 12 towards its rest position, this very rapid movement being achieved by causing the transmission pinion 10 to roll on the teeth of the toothed crown 8 which remains substantially immobile, to reach the configuration illustrated in FIGS. 3a and 3b.

[0056] At the same time, the winding lever 26 advantageously remains held under tension by the associated timepiece mechanism, for example by the striking barrel in the case of a striking mechanism, and moves towards its rest position at a rate defined by the timepiece mechanism. Thus, in the case of a striking mechanism typically comprising a speed regulator for regulating the speed of the striking, the speed of movement of the winding lever 26 towards its rest position is advantageously dictated by the speed regulator.

[0057] During this movement of the arming lever 26, its finger 24 acts on the slide 20 to move it towards its rest position as is more particularly apparent from FIG. 3a until returning to the configuration illustrated in FIG. 1a.

[0058] In the event of insufficient winding, that is to say without the corresponding clock mechanism being triggered, the shuttle 12 can quickly return to its rest position under the effect of the action of the elastic return member 14, and it can preferably be provided that the mechanical energy transmitted to the clock mechanism is directly released at the winding lever 26 to quickly return it to its rest position.

[0059] As highlighted above, the actuating device 1 according to the present invention makes it possible to actuate a striking mechanism regardless of its type (variable or constant travel of its control member), the spring 30 carried by the winding lever 26 making it possible more particularly, by its action on the slide 20, to ensure a return to the locking configuration independently of the travel of the levers involved in the operation of the striking mechanism.

[0060] It is understood that the actuating device 1 which has just been described can also operate in relation to an external control member produced in the form of a target acting on the toothed crown 8 to move it.

[0061] However, according to the present preferred embodiment of the invention, this external control member takes the form of a control crown 2 of particular construction, which could also be implemented with other types of mechanisms, such as for example a rotating flange (or rotating internal bezel) implemented in a diving watch or as part of a display of an additional time zone or even universal times.

[0062] The construction of this external control crown 2 according to the present preferred embodiment will now be described in relation to FIGS. 4a to 4c.

[0063] The control crown 2 is capable of occupying three distinct axial positions to actuate different mechanisms of the associated watch movement.

[0064] Figure 4a illustrates the configuration of the control crown 2 in its neutral position.

[0065] Conventionally, the control crown 2 is intended to be mounted on the case of the corresponding timepiece by cooperating with a tube 100 intended to be made integral with the case and defining a passage for the stem 4.

[0066] The control crown 2 comprises a hollow cap 102 defining a housing in which it comprises a barrel 104. A sleeve 106 is secured to the barrel 104. A connecting member 108 to the rod 4 is housed in the sleeve 106, as well as a transmission member 110 whose center is hollow to define a through passage for the rod 4.

[0067] The transmission member 110 comprises a Breguet toothing 112, at its free end, arranged in mesh with a Breguet toothing 114 provided on the control pinion 6, so as to be able to drive it in rotation, as mentioned above, to actuate the associated timepiece mechanism. A stop (not visible) is preferably provided to prevent a movement of the shuttle 12 beyond its rest position illustrated in FIG. 1a, thus preventing the external control crown 2 from pivoting in the opposite, non-functional direction of rotation.

[0068] It is of course possible to provide that the rod 4 also carries a sliding pinion (not shown), in a conventional manner, to ensure the winding of a barrel spring of the watch movement.

[0069] The external wall of the sleeve 106 is provided with an annular groove 116 partially housing an annular indexing member 118, possibly an O-ring seal (which would however not be intended to fulfill a sealing role).

[0070] The tube 100 also comprises two internal and annular grooves 120, 122 intended to cooperate with the indexing member 118. In the rest position of the control crown 2, the indexing member 118 is arranged in the first groove 120.

[0071] An O-ring seal 124 is interposed between the tube 100 and the cap 102 to ensure the sealing of the control crown 2, in a conventional manner.

[0072] Figure 4b illustrates the configuration of the control ring 2 when it is pulled into its first pulled axial position.

[0073] In this position, the indexing member 118 has moved to be housed in the second groove 122 of the tube 100, while the Breguet teeth 112 and 114 have been dissociated from each other. Thus, a rotation of the control crown 2 in this first pulled axial position no longer drives the control pinion 6.

[0074] For example, it may be provided that the rotation of the control crown 2 in this first pulled-out axial position can be used to wind the barrel of the watch movement. Of course, those skilled in the art may provide for actuating other mechanisms without departing from the scope of the present invention as defined by the appended claims.

[0075] Figure 4c illustrates the configuration of the control ring 2 when it is pulled into its second pulled axial position.

[0076] In this position, the indexing member 118 has moved to disengage from the tube 100, while the Breguet teeth 112 and 114 are still dissociated from each other. Thus, a rotation of the control crown 2 in this second pulled axial position also does not drive the control pinion 6.

[0077] It may advantageously be provided that the passage of the control crown 2 from its first pulled-out position to its second pulled-out position actuates a puller (not visible) acting on the sliding pinion to move it, in a conventional manner. Thus, a rotation of the control crown 2 in the second pulled-out axial position can be used to set the time of the timepiece, in a known manner.

[0078] Thanks to the construction which has just been described, it is possible to produce a control crown 2 of conventional appearance and whose handling is similar to that of a standard control crown, but allowing the actuation of a specific watch mechanism. Thus, the corresponding timepiece can have a sober appearance while having additional functionalities in reference to a timepiece which would not have a particular complex watch mechanism such as a minute repeater and/or an automaton.

[0079] The foregoing description seeks to describe a particular embodiment by way of non-limiting illustration and the invention is not limited to the implementation of certain particular features that have just been described, such as for example the manner in which the user's action on an external control member is transmitted to the shuttle to ensure the movement of the winding lever and to make it pass from its rest position to its actuating position and the corresponding technical elements, as described. A person skilled in the art will not encounter any particular difficulty in adapting the present teaching according to his own needs and producing an actuating device possibly making it possible to precisely control the moment of triggering of the timepiece mechanism associated with it, without departing from the scope of the invention as defined by the appended main claim. Thus, it is possible, for example, to provide for the implementation of the actuating device according to the present invention in relation to a timepiece mechanism of the countdown type.

[0080] Various alternative embodiments are possible without departing from the scope of the invention as defined by the claims. In particular, it is possible to provide that the shuttle acts directly on the winding lever and carries a rotary lock that can be returned to its locked state by cooperating with a fixed stop when the shuttle returns to its first position. Furthermore, it is also possible to provide that this rotary lock is pivoted, to pass into its neutral state, by cooperating with another fixed stop when the shuttle reaches its second position, in the context of the implementation with a timepiece mechanism of the constant winding type. Furthermore, in the case where the shuttle moves the actuating member by means of a slide, it is also possible, alternatively, to provide that the slide has lateral teeth and that the actuating member comprises a toothed pinion arranged in engagement with the lateral teeth of the slide.
