Description

TECHNICAL FIELD

[0001] The invention relates to a device for manually controlling a mechanism of a timepiece, comprising a manual corrector actuator arranged to be operated by a user and controlling the movement of a same wheel set in opposite directions.

[0002] The invention also relates to a timepiece comprising at least one mechanism, at least one corrector wheel set of which is arranged to be controlled by at least one such manual control device.

[0003] The invention relates to the field of timepiece mechanisms, in particular complex function mechanisms such as a calendar mechanism or a time zone mechanism, and to the setting mechanisms associated therewith, which allow the adjustment of the timepiece by a user. BACKGROUND

[0004] In the field of timepieces, watches with complex functions such as a calendar mechanism or a so-called GMT mechanism displaying time zones are not uncommon, which mechanisms are easily correctable by a user using a manual corrector actuator such as a push button.

[0005] In this particular example of a time zone mechanism, the watch has two separate push buttons for correcting the time zone in both directions (for advancing and retreating the time zone). For example, a solution is to use two correctors which act in opposite ways on a same time zone corrector wheel.

[0006] When the user actuates one of the manual actuators associated with one of the correctors, in a first step, the manual actuator pushes the corrector via a stud pressed into the manual actuator until it comes into contact with the bottom of the teeth of the time zone corrector wheel. In a second step, if the user continues to push the control, the corrector drives the teeth of the time zone corrector wheel until it reaches a stop. When the user releases the manual actuator, the return spring of the corrector releases the corrector from the teeth of the time zone corrector wheel in a third step and brings the corrector and its manual actuator back to the stop in the rest position in a fourth step. The two opposite correctors work in the same way and act on a same time zone corrector wheel. Therefore, if the user actuates the correctors simultaneously via their manual actuators, this action can lead to the breaking of the teeth of the time zone corrector wheel and / or other damage inside the mechanism.

[0007] To overcome this drawback, the Swiss patent document CH 699 785 proposes the use of a safety lock to neutralize any simultaneous activation of the two manual actuators. However, the proposed architecture confers a priority or a pre-eminence of one of the manual corrector actuators over the other. Thus, in the event of simultaneous activation of the two manual corrector actuators, this mechanism will preferentially move the local hour hand one hour forward or one hour backward, depending on the mounting direction of the safety lock within the mechanism. SUMMARY

[0008] The object of the present invention is to make the correction mechanism reliable, this correction mechanism comprising two opposite-acting correctors acting on the same mechanism, more particularly on the same corrector wheel pair, so as to avoid damage in the event of simultaneous pressing of the two correction buttons by the user.

[0009] The object of the present invention is also to propose an architecture of a manual control device for a correction mechanism which does not confer a priority on a particular manual corrector actuator, so that the only result in the event of simultaneous activation of the two manual corrector actuators is no correction, compared to the devices of the prior art.

[0010] The invention will be illustrated and described hereinafter by this non-limiting application in the case of a time zone correction mechanism comprising two manual corrector actuators, for example buttons.

[0011] To this end, the invention relates to a device for manually controlling a mechanism of a timepiece, comprising two opposite-acting manual corrector actuators arranged to be operated by a user and to control opposite movements of the same corrector wheel pair, each of the two manual corrector actuators driving an associated corrector having a beak configured to bear against a relief of the corrector wheel pair and to cause the movement of the corrector wheel pair when the manual corrector actuator is moved over its entire path of travel under the action of the user, the manual control device comprising a locking lever mechanism arranged to prevent the other of the two manual corrector actuators from acting on the corrector wheel pair when one of the two manual corrector actuators engages and interacts with the corrector wheel pair, characterized in that the locking lever mechanism comprises a locking lever configured to be driven in rotation during the engagement of one of the two manual corrector actuators so as to limit the travel of the other of the two opposite-acting manual corrector actuators and to prevent the approach of the corrector associated therewith to the corrector wheel pair.

[0043] - Figure 7A first case is shown in which the correctors are actuated simultaneously.

Since the action of each manual corrector actuator on the safety lever is opposite to that of the other manual corrector actuator, the rotation of the safety lever is blocked.

[0052] As shown diagrammatically in Figure 13, the application relates to a device 100 for manually controlling a mechanism 500 of a timepiece 1000, comprising manual corrector actuators 30, 50, which are arranged to be operated by a user and control a same wheel train 10 in opposite directions.

[0053] The application is described here in the non-limiting application of a time zone correction mechanism comprising two manual corrector actuators 30, 50 acting in opposite directions, in this case control buttons, which tend to cause the rotation of a correction wheel train 10, in this case a time zone correction wheel, in two opposite directions (clockwise and counterclockwise). Figure 1

[0054] The first manual corrector actuator 30 can be directly operated by the user by a push action in a first direction A. The first manual corrector actuator 30 is mounted so that it pivots about a first articulation pin 31 pressed into the bridge 1 of the mechanism 500, so that the first manual corrector actuator 30 pivots about the first articulation pin 31 under the action of the user.

[0055] The manually controlled device 100 also comprises a first corrector 20 articulated relative to the first manual corrector actuator 30. To this end, the first corrector 20 comprises a first elongated guide groove 23 configured to cooperate with the first articulation pin 31 so as to allow the articulation of the first corrector 20 relative to the first manual corrector actuator 30.

[0056] The first elongated groove 23 is configured to guide the first corrector in a rotational and translational movement when the first manual corrector actuator 30 pivots.

[0057] The first manual corrector actuator 30 comprises a first actuation post 32, for example pressed into the body of the first manual corrector actuator 30. The first actuation post 32 allows the transmission of the push action exerted by the user on the first manual corrector actuator 30 to the first corrector 20.

[0058] The cooperation between the first elongated groove 23 and the first articulation pin 31 limits the relative travel between the first manual corrector actuator 30 and the first corrector 20.

[0059] The first manual corrector actuator 30 tends to be pushed back, directly or indirectly, by a first elastic return means 22 in a second direction B opposite the first direction A, in this case a spring, but not limited thereto, to an inactive rest position.

[0060] ​In the exemplary embodiment shown, the first elastic return means 22 abut against the first corrector 20, more specifically against a first spring pin 21 which is pressed into the body of the first corrector 20. Thus, thanks to this architecture, the first elastic return means 22 make it possible to push both the first corrector 20 and the first manual corrector actuator 30 back into the inactive rest position in a second direction B opposite the first direction A.

[0061] According to an alternative embodiment, the first elastic return means 22 can also be formed by two independent return springs, the first spring acting on the first corrector 20 and the second spring acting on the first manual corrector actuator 30.

[0062] The first corrector 20 comprises a first corrector beak 29 which is arranged to cooperate with the reliefs of the corrector wheel pair 10, which in this case is formed by the time zone corrector wheel. The reliefs of the corrector wheel pair 10 are for example the teeth 11 of the toothing of the corrector wheel pair 10. Advantageously, the first actuation post 32 can also be arranged to constitute an abutment for limiting the angular travel of the first corrector 20.

[0063] According to an alternative embodiment, the corrector wheel pair 10 can be constituted by a corrector star wheel or other element. In this case, the first beak 29 is thus arranged to cooperate with the branches, arms, catches or other elements included in the considered corrector wheel pair 10. The corrector wheel pair 10 is generally held in place by a corrector wheel pair jumper 60 which is subjected to the action of a jumper spring 63 which abuts against a jumper pin 62.

[0064] Similarly, the manual control device 100 comprises a second manual corrector actuator 50 which can be directly operated by the user via a push action in a third direction C. The second manual corrector actuator 50 is mounted so that it pivots about a second articulation pin 51 which is pressed into the clamping plate 1 of the mechanism 500, so that under the action of the user, the second manual corrector actuator 50 pivots about the second articulation pin 51.

[0065] The manual control device 100 also comprises a second corrector 40 which is articulated with respect to the second manual corrector actuator 50. To this end, the second corrector 40 comprises a second elongated guide groove 43 which is configured to cooperate with the second articulation pin 51 so as to allow the second corrector 40 to be articulated with respect to the second manual corrector actuator 50.

[0066] The second elongated groove 43 is configured to guide the second corrector 40 in a rotational and translational movement when the second manual corrector actuator 50 is pivoted.

[0067] The second manual corrector actuator 50 comprises a second actuation post 52, for example pressed into the body of the second manual corrector actuator 50. The second actuation post 52 allows the transmission of the thrust action exerted by the user on the second manual corrector actuator 50 to the second corrector 40.

[0068] The cooperation between the second elongated groove 43 and the second articulation pin 51 limits the relative travel between the second manual corrector actuator 50 and the second corrector 40. The second manual corrector actuator 50 tends to be pushed back, directly or indirectly, by the second elastic return means 42, which in this case are constituted by a spring, but not limited thereto, in a fourth direction D opposite to the third direction C, to an inactive rest position.

[0069] In the exemplary embodiment shown, the second elastic return means 42 abut against the second corrector 40, more specifically against a second spring pin 41 pressed into the body of the second corrector 40. Thus, thanks to this architecture, the second elastic return means 42 make it possible to push back both the second corrector 40 and the second manual corrector actuator 50 in the fourth direction D opposite to the third direction C, to an inactive rest position.

[0070] According to an alternative embodiment, the second elastic return means 42 can also be formed by two independent return springs, the first spring acting on the second corrector 40 and the second spring acting on the second manual corrector actuator 50.

[0071] The second corrector 40 comprises a second corrector beak 49 arranged to cooperate with the concave-convex portion of the corrector wheel set 10, for example with the teeth 11 of the toothed portion of the corrector wheel set 10. Advantageously, the second actuation post 52 can also be arranged to constitute an abutment for limiting the angular travel of the second corrector 40.

[0072] Figure 2 More specifically, a first step is shown, which corresponds to the thrust exerted by the user on the first manual corrector actuator 30 in the first direction A. This thrust causes the first corrector 20 to rotate, which pivots in the direction SH and abuts against the bottom of the toothed portion on the corrector wheel set 10. In this first step, the first corrector 20 is displaced in a substantially linear manner to the stop position of the first manual corrector actuator 30. Figure 2 In the diagram shown, the direction SH corresponds to the clockwise direction.

[0073] Figure 3 More specifically, a second step is shown, which occurs when the first corrector 20 abuts against the bottom of the toothed portion on the corrector wheel set 10. In this second step, a thrust is exerted to displace the first corrector 20 in a substantially linear manner to the stop position of the first manual corrector actuator 30, and in the meantime, the displacement of the first corrector 20 induces the pivoting of the corrector wheel set 10 in the direction SH, which in the exemplary embodiment shown is the clockwise direction.

[0074] It is noted that in this non-limiting exemplary embodiment, the direction of rotation of the first corrector 20 corresponds to the direction of rotation of the corrector wheel set 10, the first corrector 20 acting directly on the corrector wheel set 10 and not via intermediate elements or gear trains.

[0075] However, intermediate elements can optionally be used between the corrector 20 and the corrector wheel set 10, such that the rotation of the first corrector 20 drives the corrector wheel set 10 in a direction opposite to the rotation of the first corrector 20.

[0076] Figure 4 A third step is shown, which comprises the release of the first manual corrector actuator 30 by the user, which, under the action of the first elastic return means 22, pivots with the first corrector 20 in a second direction SAH, which in this exemplary embodiment corresponds to the counterclockwise direction, so as to move the first beak 29 out of the toothed portion of the corrector wheel set 10.

[0077] Figure 5 A fourth step is shown, which corresponds to the complete release of the first manual corrector actuator 30 and the repositioning thereof in the rest position, in the stop.

[0078] The second manual corrector actuator 50 and the second corrector 40 associated therewith function similarly to the first manual corrector actuator 30 and the first corrector 20 as described with reference to Figures 2 to 5 The optional embodiments proposed for the first manual corrector actuator 30 and its first corrector 20 are equally applicable to the second manual corrector actuator 50 and its second corrector 40.

[0079] Advantageously, the two correctors 20, 50 are opposite correctors that work in the same way and act on the same corrector wheel set 10.

[0080] Advantageously, the two correctors 20, 50 act symmetrically on the same corrector wheel set 10.

[0081] Advantageously, the manual control device 100 further comprises means for neutralizing / compensating the two simultaneous opposite corrections.

[0082] Furthermore, according to the present application, the manual control device 100 comprises a locking lever mechanism arranged to block the action of one of the manual corrector actuators 30, 50 on the corrector wheel set 10 when the other manual corrector actuator 30, 50 is interacting with the corrector wheel set 10.

[0083] According to the application, each manual corrector actuator 30, 50 tends to be pushed back, directly or indirectly, by a resilient return means 22, 42, which constitutes the only resilient return means of the mechanism connecting the manual corrector actuator 30, 50 under consideration to the corrector wheel set 10, into an inactive rest position. Furthermore, each manual corrector actuator 30, 50 is articulated with a corrector 20, 40 comprising a beak 29, 49 arranged, under the action of the user, over the complete stroke path of the manual corrector actuator 30, 50, to abut against the relief of the corrector wheel set 10 to move the corrector wheel set 10.

[0084] The locking lever mechanism can comprise a locking lever 70 arranged to be driven during the movement of one of the manual corrector actuators 30, 50 and to limit the stroke of the other of the manual corrector actuators 50, 30, thereby preventing the associated corrector 40, 20 from approaching the corrector wheel set 10.

[0085] Advantageously, the locking lever 70 is driven to rotate during the movement of one of the manual corrector actuators 30, 50.

[0086] In a first alternative embodiment, the locking lever 70 is monolithic.

[0087] In a second alternative embodiment, the locking lever 70 is made of several parts articulated with each other.

[0088] In a third alternative embodiment, the locking lever 70 is made of several parts arranged to abut against each other when the user exerts an action on one of the manual corrector actuators 30, 50.

[0089] Such a locking lever 70 is mounted so that it can rotate about an axis perpendicular to the clamping plate 1 and forms a safety lever to ensure that the correctors 20, 40 do not simultaneously drive the corrector wheel set 10, which is, for example, a time zone corrector wheel in the non-limiting example application herein.

[0090] Such a locking lever 70 is configured so that it does not prioritize a particular manual corrector actuator 30, 50 as is the case with prior art manual control devices. Thus, the manual control device 100 according to the application allows prioritizing the manual corrector actuator that is first actuated by the user, rather than the manual corrector actuator that is predefined at the design stage. Thus, the manual control device according to the application allows not giving priority to either of the front and rear correctors at the design stage.

[0091] The locking lever 70 is more particularly shown in its entirety in Figure 6 ​

[0092] Figure 6 In the same aspect as in Figure 1 , the manual control device 100 and the locking lever mechanism in the rest position are particularly shown in the absence of any action by the user.

[0093] More specifically, the locking lever 70 is formed as a lever having stop finger portions 71, 72 at opposite ends thereof, each of which is arranged to cooperate with a portion of the manual corrector actuator 30, 50 while abutting against it.

[0094] The two opposite ends of the locking lever 70 have the same shape and perform the same function.

[0095] Each manual corrector actuator 30, 50 further comprises a plurality of bearing profiles, allowing interaction with the locking lever 70, more specifically with the stop finger portions 71, 72, according to the action of the user.

[0096] As shown in Figures 7 to 9 , each manual corrector actuator 30, 50 comprises a first bearing profile 37, 57, configured to form a stop profile of the manual corrector actuator 30, 50, the first bearing profile 37, 57 being configured to cooperate with the stop finger portions 71, 72 of the locking lever 70, respectively.

[0097] Each manual corrector actuator 30, 50 comprises a second bearing profile 36, 56, configured to form a detent profile or a sliding profile, on which the stop finger portions 71, 72 of the locking lever 70 slide, thus allowing the manual corrector actuators 30, 50 to rotate at least partially when the manual corrector actuators 30, 50 are not simultaneously actuated, as more particularly shown in Figures 8 to 9 .

[0098] When the user operates the manual corrector actuators 30, 50, two situations can occur.

[0099] In a first situation, as shown in Figure 7 , the manual corrector actuators 30, 50 are simultaneously actuated by the user. When the manual corrector actuators 30 and 50 are simultaneously actuated, they simultaneously come into contact with the stop finger portions 71, 72 of the locking lever 70 at the first bearing profiles 37, 57. Thus, the first bearing profiles 37, 57 simultaneously abut against the stop finger portions 71, 72 of the locking lever 70. Since each manual corrector actuator 30, 50 exerts an opposite and identical action to the other manual corrector actuator on the locking lever 70, which is capable of rotational movement, the locking lever 70 cannot rotate.

[0100] The result of this simultaneous action on both manual corrector actuators 30, 50 is that the only way to achieve correction is to release one of the manual corrector actuators 30, 50 to allow the locking lever 70 to tip.

[0101] In this way, when the user simultaneously activates both corrector beaks 29 and 49 via the manual corrector actuators 30, 50, the locking lever mechanism prevents both corrector beaks 29 and 49 from interacting with the corrector wheel set 10.

[0102] Advantageously, the stop fingers 71, 72 have the same first shape and the first bearing profiles 37, 57 have the same second shape, so that the force exerted on the locking lever 70 via the manual corrector actuators 30, 50 is substantially equal.

[0103] In the second case, as shown in Figure 8 the user only actuates one of the manual corrector actuators 30, 50 at a time.

[0104] In the example embodiment shown in Figure 8 the first manual corrector actuator 30 is actuated. As seen above, this first manual corrector actuator 30 actuates the corrector 20, which acts in the clockwise correction direction until the corrector beak 29 comes into contact with the teeth 11 of the toothed portion of the corrector wheel set 10.

[0105] The rotation of the manual corrector actuator 30 brings the first bearing profile 37 into contact with the first finger 71 of the locking lever, causing the locking lever 70 to rotate over its maximum stroke.

[0106] Advantageously, the bearing profiles 37, 36 of the manual corrector actuator 30 are configured so that the maximum stroke of the locking lever 70 is reached before the corrector beak 29 comes into contact with the toothed portion of the corrector wheel set 10.

[0107] Once tipped, the locking lever 70 is held in the tipped position by the second bearing profile 36. In the tipped position, the distance between the locking lever 70 and the second manual corrector actuator 50 is very small, which prevents the rotation of the second manual corrector actuator 50 and the rotation of the second corrector 40, thus preventing the actuation of the second manual corrector actuator 50 once the first manual corrector actuator 30 is engaged. There can be a small amount of play.

[0108] If the user continues to push the first manual corrector actuator 30 until it is as shown in Figure 9With the locking lever 70 shown in the locked position, the action will drive the corrector wheel set in a clockwise direction. The locking lever 70 is kept in the same tilted position by sliding along the second bearing profile 36 and prevents the second manual corrector actuator 50 from rotating. Thus, via the locking lever 70 acting as a safety lever, both corrector beaks 29 and 49 cannot interact with the corrector wheel set 10 at the same time and no corrector is given priority at the design stage.

[0109] Depending on the geometry and complexity of the mechanism, the manual corrector actuators 30, 50 can have a clearance 38, 58 to free up space opposite the finger 71, 72 of the locking lever 70, allowing the locking lever 70 to tilt and reach maximum travel.

[0110] In the alternative embodiment shown in Figure 11, the locking lever 70 comprises a lever guide groove 73 cooperating with a lever guide pin 173 carried by the clamping plate 1 carrying the manual control device 100.

[0111] According to another alternative embodiment, the locking lever comprises a lever pin cooperating with a lever pin guide groove formed in the clamping plate 1 carrying the manual control device 100.

[0112] According to another alternative embodiment shown in Figure 12, the locking lever 70 is mounted so that it pivots around a shaft 174 mounted on the clamping plate 1 carrying the manual control device 100.

[0113] In one alternative embodiment, the locking lever 70 and the manual corrector actuators 30, 50 are coplanar in the mechanism 500.

[0114] In one alternative embodiment, the locking lever 70 and the manual corrector actuators 30, 50 can be positioned in different planes of the mechanism 500, facilitating the integration of the control device 100.

[0115] In one alternative embodiment, the locking lever 70 and the manual corrector actuators 30, 50 and / or the correctors 20, 40 associated therewith can be positioned in different parallel planes of the mechanism 500, facilitating the integration of the control device 100.

[0116] In one alternative embodiment, the locking lever 70 can cooperate with the manual corrector actuators 30, 50 positioned in two different parallel planes of the mechanism 500.

[0117] The locking lever 70 can also be used to activate one or more additional functions during the tilting of the locking lever 70. In particular, as Figure 1 and 6As shown, the locking lever 70 can comprise a coupling pin 74 which moves integrally with the locking lever 70. This coupling pin 74 is arranged in particular to move a further wheel pair, for example a coupling wheel pair, in order to couple or decouple the correction mechanism with the hands of the watch during the movement of the locking lever 70 which is activated during the correction.

[0118] Each manual corrector actuator 30, 50 comprises a limit member for limiting the angular travel. A manual control device 100 according to the application has been shown with reference to Figure 10, in which the aforementioned correctors 20, 40 have not been shown for better visibility. More particularly, the limit member for limiting the angular travel is formed by a limit groove 39, 59 formed in the body of the manual corrector actuator 30, 50 and by a limit pin 208, 408 carried by the bridge 1 which carries the manual control device 100. The limit groove 39, 59 cooperates with the limit pin 208, 408 in such a way that, in the rest position, under the action of the first or second elastic return means 22, 42, the limit groove 39, 59 abuts against the limit pin 208, 408 at a first end of the limit groove 39, 59. The maximum rotational travel of the manual corrector actuator 30, 50 is defined by the second end of the limit groove 39, 59 abutting against the limit pin 208, 408 under the pushing action activated by the user.

[0119] The inactive rest position of each of the manual corrector actuators 30, 50 is external to the watch 1000. These manual corrector actuators 30, 50 are thus kept within reach of the user.

[0120] More particularly, the manual corrector actuators 30, 50 are actuated by means of a pushbutton provided in the middle piece (not shown) of the watch 1000.

[0121] The application also relates to a watch 1000 comprising at least one mechanism 500, at least one correction wheel pair 10 of which is arranged to be controlled by at least one such manual control device 100.

[0122] By way of example, the mechanism 500 is a time zone mechanism, in which case the correction wheel pair 10 is a time zone correction wheel.

[0123] By way of example, the mechanism 500 is a calendar mechanism, in which case the correction wheel pair 10 is a date wheel or a date ring.

[0124] The application is applicable to many other watch mechanisms for which the user must make an adjustment or advantageously can make an adjustment, for example, in a non-limiting manner, the setting of the phases of the moon or the years, the state of the tides, the leap years, the position of the day / night, the position of the morning / afternoon, the manual counters, the selection of the time announcement mode, or the adjustment of the alarm time, etc.
