Description

Technical field of the invention

The invention relates to a manual control device for a mechanism for a timepiece, comprising manual corrector actuators, which are arranged to be operated by a user, and to control movements in the opposite direction to the same motive.

The invention also relates to a timepiece, comprising at least one mechanism, of which at least one correction mobile is arranged to be controlled at least by such a manual control device.

The invention relates to the field of watchmaking mechanisms, in particular complication mechanisms such as calendar mechanisms or time zone mechanisms, and the associated adjustment mechanisms, allowing adjustment by the user of the piece of watchmaking.

Technology background

[0004] In watchmaking, it is not uncommon to offer watches with complications, such as calendar mechanisms, or even so-called GMT mechanisms displaying time zones, which the user can easily correct using manual corrector actuators, such as pushers.

[0005] In this particular example of a time zone mechanism, there are watches comprising two separate pushers for correcting the time zones in both directions (advance of the time zone and backward movement of the zone). For example, one solution consists in using two correction actuators which act on the same single spindle correction wheel, in an antagonistic manner.

[0006] When the user actuates a manual actuator associated with a corrector, in a first step, this manual actuator pushes this corrector via a stud driven into the manual actuator until it comes into contact with the bottom of the teeth of the spindle correction wheel. If the user continues to push the control, the corrector drives the spindle correction wheel tooth to a stop, in a second stage. When the user releases the manual actuator, the corrector return spring disengages the corrector from the toothing of the spindle correction wheel during a third stage, and brings the corrector and its manual actuator back to a stop in resting position in a fourth step. The two opposing correctors operate in the same way, and act on the same spindle correction wheel. Therefore, if the user operates the correctors via their manual actuators at the same time, this action may cause the spindle correction wheel teeth to break and/or other damage to the mechanism.

To overcome this drawback, it has been proposed in document CH 699 785 to use a safety lock to neutralize simultaneous activation of the two manual actuators. However, the proposed architecture gives priority or preponderance to one of the manual corrector actuators vis-à-vis the other. Thus, in the event of simultaneous actuation of the two manual corrector actuators, such a mechanism prioritizes either advancing the local time hand by one hour, or setting the time hand back by one hour. the local time according to the direction of assembly of the security lock in the mechanism.

Summary of the invention

The invention aims to secure a correction mechanism comprising two antagonistic correctors acting on the same mechanism, and more precisely on the same mobile correction, to avoid breakage when the user presses the two correction buttons in same time.

[0009] The invention also aims to propose an architecture of a manual control device for a correction mechanism making it possible not to prioritize a manual corrector actuator in particular, so that the unique consequence in the event of simultaneous actuation of the two manual corrector actuators is the absence of any correction unlike the devices of the state of the art.

The invention will be illustrated and described below in a non-limiting application to the case of a spindle correction mechanism comprising two manual corrector actuators, for example pushers.

Detailed description of the invention

As illustrated schematically in Figure 13, the invention relates to a manual control device 100 of a mechanism 500 for a timepiece 1000, comprising manual corrector actuators 30, 50, which are arranged to be operated by a user, and to control the same correction mobile 10 in movements in the opposite direction.

The invention is described here in a non-limiting application to the case of a spindle correction mechanism, illustrated in Figure 1, comprising two manual corrector actuators 30, 50 antagonists, which are here more particularly control, which tend to rotate the correction mobile 10, which here is a spindle correction wheel, in two opposite directions (clockwise and anti-clockwise).

A first corrector manual actuator 30 is directly operable by a user in a pushing action in a first direction A. The first corrector manual actuator 30 is pivotally mounted around a first hinge pin 31 driven in a plate 1 of the mechanism 500, so that under the action of the user, the first manual corrector actuator 30 pivots around the first hinge pin 31.

The manual control device 100 also comprises a first corrector 20 articulated with respect to the first corrector manual actuator 30. For this purpose, the first corrector 20 comprises a first oblong guide groove 23 configured to cooperate with the first pin of joint 31 so as to allow the articulation of the first corrector 20 with respect to the first manual corrector actuator 30.

The first oblong groove 23 is configured to guide the movement of the first corrector during the pivoting of the first manual corrector actuator 30, according to a movement of rotation and translation.

The first corrector manual actuator 30 comprises a first actuating stud 32, for example driven into the body of the first corrector manual actuator 30. The first actuating stud 32 makes it possible to transmit to the first corrector 20, the pushing action exerted on the first manual corrector actuator 30 by the user.

The cooperation of the first oblong groove 23 and the first hinge pin 31 limits the relative travel between the first manual corrector actuator 30 and the first corrector 20.

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

In the illustrated embodiment, the first elastic return means 22 bears on the first corrector 20, and more particularly on a first spring pin 21 driven into the body of the first corrector 20. Thus, thanks to this architecture, the first elastic return means 22 makes it possible to push back, in a second direction B opposite the first direction A, towards an inactive rest position, both the first corrector 20 and the first manual corrector actuator 30.

It is also envisaged according to a variant embodiment that the first elastic return means 22 be formed by two independent return springs, a first spring acting on the first corrector 20 and a second spring acting on the first manual corrector actuator 30.

The first corrector 20 comprises a first corrector beak 29 which is arranged to cooperate with a relief of the correction mobile 10, here formed by a spindle correction wheel. The relief of the correction mobile 10 is for example a tooth 11 of the toothing of the correction mobile 10. The first actuation stud 32 can also, advantageously, be arranged to constitute a stop for limiting the angular travel of the first corrector 20 .

[0030]According to a variant embodiment, the correction mobile 10 could be constituted by a correction star, or the like. In this case, the first beak 29 is then arranged to cooperate with a branch, an arm, a lug, or other, that includes the correction mobile 10 considered. The correction mobile 10 is conventionally held in position by a correction mobile jumper 60 subjected to the action of a jumper spring 63 resting on a jumper pin 62.

Similarly, the manual control device 100 comprises a second corrector manual actuator 50 which is directly operable by a user in a pushing action in a third direction C. The second corrector manual actuator 50 is mounted in such a way pivoting around a second hinge pin 51 driven into the plate 1 of the mechanism 500, so that under the action of the user, the second manual corrector actuator 50 pivots around the second hinge pin 51.

The manual control device 100 also comprises a second corrector 40 articulated with respect to the second corrector manual actuator 50. For this purpose, the second corrector 40 comprises a second oblong guide groove 43 configured to cooperate with the second pin of joint 51, so as to allow the articulation of the second corrector 40 with respect to the second manual corrector actuator 50.

The second oblong groove 43 is configured to guide the movement of the second corrector 40 during the pivoting of the second corrector manual actuator 50, according to a movement of rotation and translation.

The second corrector manual actuator 50 comprises a second actuating stud 52, for example driven into the body of the second corrector manual actuator 50. The second actuating stud 52 makes it possible to transmit to the second corrector 40, the pushing action exerted on the second manual corrector actuator 50 by the user.

The cooperation of the second oblong groove 43 and the second hinge pin 51 limits the relative travel between the second corrector manual actuator 50 and the second corrector 40. The second corrector manual actuator 50 tends to be pushed back, directly or indirectly, in a fourth direction D opposite the second direction C, towards an inactive rest position by a second elastic return means 42, here not limited to a spring.

In the illustrated embodiment, the second elastic return means 42 rests on the second corrector 40, and more particularly on a second spring pin 41 driven into the body of the second corrector 40. Thus, thanks to this architecture, the second elastic return means 42 makes it possible to push back, in a fourth direction D opposite to the third direction C, towards an inactive rest position, both the second corrector 40 and the second manual corrector actuator 50.

It is also envisaged according to a variant embodiment that the second elastic return means 42 be formed by two independent return springs, a first spring acting on the second corrector 40 and a second spring acting on the second manual corrector actuator 50 .

This second corrector 40 comprises a second corrector beak 49 which is arranged to cooperate with a relief of the correction mobile 10, for example a tooth 11 of the toothing of the correction mobile 10. The second actuation stud 52 can also, advantageously, be arranged to constitute an angular stroke limiting stop of the second corrector 40.

[0039] Figure 2 more particularly illustrates a first step corresponding to a thrust given by the user on the first corrector manual actuator 30 in the first direction A. This thrust drives the first corrector 20 in rotation, which pivots in the direction SH, and comes to bear at the bottom of the toothing on the correction mobile 10. In the representation illustrated in FIG. 2, the direction SH corresponds to the clockwise direction.

[0040] Figure 3 more particularly illustrates a second step occurring when the first corrector 20 comes to bear at the bottom of the toothing on the correction mobile 10. In this second step, the thrust is exerted so as to move, in a substantially rectilinear manner , the first corrector 20 as far as an abutment position of the first corrector manual actuator 30, and during which the movement of the first corrector 20 initiates pivoting of the correction mobile 10 in the direction SH, which is clockwise in our example illustrated.

[0041] It will be noted that in our non-limiting example of embodiment, the direction of rotation of the first corrector 20 corresponds to the direction of rotation of the correction mobile 10, the first corrector 20 acting directly on the correction mobile 10 and not via an element or intermediate cog.

However, it is envisaged to be able to use an intermediate element between the corrector 20 and the correction wheel 10 so that the rotation of the first corrector 20 drives the wheel correction 10 in a direction opposite to the rotation of the first corrector 20 .

[0043] Figure 4 illustrates a third step consisting in the release by the user of the first corrector manual actuator 30, which, under the action of the first elastic return means 22, pivots, as well as the first corrector 20 in a second direction SAH, corresponding in our embodiment to the anti-clockwise direction, to bring out the first beak 29 from the toothing of the correction mobile 10.

Figure 5 illustrates a fourth step corresponds to the complete release of the first corrector manual actuator 30 and the repositioning of the first corrector manual actuator 30, which comes back into abutment in a rest position.

The operation of the second corrector manual actuator 50 and its associated second corrector 40 is similar to the operation of the first corrector manual actuator 30 and the first corrector 20, as described with reference to Figures 2 to 5. The variants of embodiment proposed for the first manual corrector actuator 30 and its first corrector 20 are also applicable to the second manual corrector actuator 50 and its second corrector 40.

Advantageously, the two correctors 20, 50 are antagonistic correctors which operate in the same way, and which act on the same correction mobile 10.

Advantageously, the two correctors 20, 50 act symmetrically on the same correction mobile 10.

Advantageously, the manual control device 100 further comprises means for neutralizing two simultaneous antagonistic corrections.

Also, according to the invention, the manual control device 100 comprises an isolation mechanism, which is arranged to prohibit an action of one of the manual corrector actuators 30, 50, on the mobile correction 10 when the other of the manual corrector actuators 30, 50 is in interaction with the correction mobile 10.

According to the invention, each manual corrector actuator 30, 50 tends to be pushed directly or indirectly towards an inactive rest position by an elastic return means 22, 42, which constitutes the only elastic return means of the mechanism. connecting the corrector manual actuator 30, 50 considered, to the correction mobile 10. And each corrector manual actuator 30, 50, is articulated with a corrector 20, 40, which comprises a beak 29, 49, which is arranged to take pressing on a relief of the correction mobile 10 to make it move during a complete stroke of the manual corrector actuator 30, 50, under the action of the user.

The isolation mechanism may include an insulator 70, which is arranged to be driven during movement of one of the manual corrector actuators 30, 50, and to limit the travel of the other of the manual actuators of corrector 50, 30, and thus prevent access of its associated corrector 40, 20 to the correction mobile 10.

Advantageously, the insulator 70 is driven in rotation during a movement of one of the manual corrector actuators 30, 50.

In a first variant embodiment, the insulator 70 is monolithic.

In a second variant, the insulator 70 is in several parts hinged relative to each other.

In yet a third variant, the insulator 70 is in several parts, which are arranged to bear against one another during an action by a user on one of the manual corrector actuators 30, 50.

Such an insulator 70 is rotatably mounted about an axis perpendicular to the plate 1, and forms a safety rocker to ensure that the correctors 20, 40 do not drive the correction wheel 10 at the same time. , for example the spindle correction wheel in our example of non-limiting application.

Such an isolator 70 is configured not to prioritize a manual corrector actuator 30, 50 in particular as is the case with the manual control devices of the state of the art. Thus, the manual control device 100 according to the invention makes it possible to give priority to the manual corrector actuator actuated first by the user and not to prioritize a manual corrector actuator predefined during the design. The manual control device according to the invention therefore makes it possible not to prioritize the forward or backward corrector during the design.

The insulator 70 is shown in its entirety more particularly in Figure 6.

[0059] Figure 6 particularly illustrates the manual control device 100 and the isolation mechanism in the rest position, in the absence of user action, in the same way as Figure 1.

More particularly the insulator 70 forms a rocker comprising, at its opposite ends, stop fingers 71, 72, each of the stop fingers 71, 72 being arranged to cooperate in support with a portion of the manual actuators of concealer 30, 50.

The two opposite ends of the insulator 70 have an identical shape and perform the same function.

[0062] Each manual corrector actuator 30, 50 also comprises several support profiles allowing interaction with the insulator 70, and more particularly with the stop fingers 71, 72, depending on the actions of the user. .

As illustrated in Figures 7 to 9, each manual corrector actuator 30, 50 comprises a first support profile 37, 57 configured to form a stop profile of the manual corrector actuator 30, 50, the first support profile 37, 57 being configured to cooperate respectively with a stop pin 71, 72 of the insulator 70.

Each manual corrector actuator 30, 50 comprises a second support profile 36, 56 configured to form an escape profile, or even a sliding profile, on which the stop finger 71, 72 of the insulator 70 slides, so as to allow at least partial rotation of a manual corrector actuator 30, 50 when the manual corrector actuator 30, 50 antagonist is not actuated simultaneously, as shown more particularly in Figures 8 to 9 .

When the user performs maneuvers on the manual corrector actuators 30, 50, two cases may arise.

In the first case, illustrated by Figure 7, the manual corrector actuators 30, 50 are actuated simultaneously by the user. When the corrector manual actuators 30 and 50 are actuated simultaneously, they simultaneously come into contact with the stop fingers 71, 72 of the insulator 70, at the level of the first support profile 37, 57. Thus, the first support profiles 37, 57 are found simultaneously in support on a stop pin 71, 72 of the insulator 70. As each manual corrector actuator 30, 50 exerts an action opposite and identical to the other on the insulator 70, mobile in rotation, the rotation of the insulator 70 is not possible.

[0067] Following this simultaneous action on the two manual corrector actuators 30, 50, the only way to make a correction is to release one of the manual corrector actuators 30, 50 to allow the rocker of the insulator 70.

Thus, the isolation mechanism prevents the two corrector beaks 29 and 49 from interacting with the correction mobile 10 when they are activated at the same time by the user, via the manual corrector actuators 30 , 50.

Advantageously, the stop fingers 71, 72 have a first identical shape and the first support profile 37, 57 have a second identical shape so that the forces exerted on the insulator 70 via the manual corrector actuators 30, 50 are substantially equivalent.

In the second case, as seen in Figure 8, the user operates only one of the manual corrector actuators 30, 50 at a time.

In the embodiment illustrated in Figure 8, it is the first manual corrector actuator 30 which is actuated. As seen previously, this first manual corrector actuator 30 actuates the corrector 20, which acts in the direction of a time correction, until the corrector beak 29 comes into contact with a tooth 11 of the toothing of the mobile of edit 10.

The rotation of the corrector manual actuator 30 causes the contacting of the first support profile 37 on the first finger 71 of the insulator, then the rotation of the insulator 70 over its maximum stroke.

[0073] Advantageously, the support profiles 37, 36 of the manual corrector actuator 30 are configured so that the maximum travel of the insulator 70 is reached before the corrector beak 29 comes into contact with the toothing of the corrective mobile 10.

Once tilted, the insulator 70 is held in the tilted position via the second support profile 36. In the tilted position, the distance between the rocker 70 and the second manual corrector actuator 50 is very small, which prevents the rotation of the latter and of the second correction 40 and therefore the actuation of the second manual corrector actuator 50 once the first manual corrector actuator 30 is engaged. Slight play may be possible.

[0075] If the user continues to push the first manual corrector actuator 30 as far as the stop, as shown in FIG. 9, this action drives the corrector mobile clockwise. The safety rocker 70 remains in the same tilted position by sliding along the second support profile 36 and prevents the rotation of the second manual corrector actuator 50. Thus, via the insulator 70 acting as a safety rocker, the two corrector beaks 29 and 49 cannot interact with the correction mobile 10 at the same time, and no corrector is given priority during the design.

[0076] Depending on the geometry and complexity of the mechanism, the manual corrector actuators 30, 50 may have a clearance 38, 58 allowing space to be freed up opposite the fingers 71, 72 of the insulator 70, thus allowing the insulator 70 to be able to tilt and reach its maximum stroke.

In a variant illustrated in Figure 11, the insulator 70 comprises rocker guide grooves 73 cooperating with rocker guide pins 173 carried by the plate 1 carrying the manual control device 100.

According to another variant, the insulator comprises rocker pins cooperating with rocker pin guide grooves formed in the plate 1 carrying the manual control device 100.

According to another variant illustrated in Figure 12, the insulator 70 is pivotally mounted around an axis 174 mounted on the plate 1 carrying the manual control device 100.

In a variant embodiment, the insulator 70 and the manual corrector actuators 30, 50 are coplanar in the mechanism 500.

In a variant embodiment, the insulator 70 and the manual corrector actuators 30, 50 can be positioned in different planes of the mechanism 500 so as to facilitate the integration of the control device 100.

[0082] In a variant embodiment, the isolator 70 and the manual corrector actuators 30, 50 and/or the associated correctors 20, 40 can be positioned in different planes parallel to each other of the mechanism 500 so as to facilitate the integration of the control device 100.

In a variant embodiment, the insulator 70 can cooperate with manual corrector actuators 30, 50 positioned in two different and parallel planes of the mechanism 500.

[0084] The isolator 70 can also be used to initiate one or more additional functions during the tilting of the isolator 70. In particular, as illustrated in Figures 1 and 6, the isolator 70 can include a clutch pin 74 integral with the movements of the insulator 70. This clutch pin 74 is in particular arranged to, during the movement of the insulator 70 initiated during a correction, move an additional mobile, for example a mobile clutch, move a rocker provided of an idler gear, engage the correction mechanism with the timepiece hand-fitting, or even disengage it.

[0085] Each manual corrector actuator 30, 50 comprises a limiting device to limit the angular travel. The manual control device 100 according to the invention has been represented with reference to FIG. 10 without the correctors 20, 40 described above for better visibility. More specifically, the limiting member for limiting the angular stroke is formed by a limiting groove 39, 59 made in the body of the manual corrector actuator 30, 40 and by a limiting pin 208, 408 carried by the plate 1 carrying the manual control device 100. The limitation groove 39, 59 cooperates with the limitation pin 208, 408 in the following way: in the rest position, under the influence of the first elastic return means 22 or of the second means elastic return 42, the limitation groove 39, 59 bears against the limitation pin 208, 408 at a first end of the limitation groove 39, 59. The maximum rotational travel of the manual actuator of corrector 30, 50 is defined by the second end of the limiting groove 39, 59 coming into abutment against the limiting pin 208, 408 under the thrust initiated by the user.

The inactive rest position of each of the manual corrector actuators 30, 50 is outside the timepiece 1000. These manual corrector actuators 30, 50 thus remain within reach of the user.

[0087] More specifically, the manual corrector actuators 30,50 are actuated by means of pushers formed in the caseband (not shown) of the timepiece 1000.

The invention also relates to a timepiece 1000, comprising at least one mechanism 500, of which at least one correction mobile 10 is arranged to be controlled at least by such a manual control device 100.

By way of example, the mechanism 500 is a spindle mechanism, in this case the correction mobile 10 is a spindle correction wheel.
