DEVICE FOR MANUALLY CONTROLLING A MECHANISM FOR A CLOCK

Description

Technical field of the invention

[0001] The invention relates to a device for manually controlling a mechanism for a timepiece, comprising manual corrector actuators, which are arranged to be operated by a user, and to control movements in opposite directions of the same mobile.

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

[0003] The invention relates to the field of watch 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 timepiece. Technological background

[0004] In watchmaking, it is not uncommon to offer watches with complications, such as calendar mechanisms, or 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 with two separate pushers to correct the time zones in both directions (forward and backward). For example, one solution is to use two correction actuators that act on a single time zone 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 tooth of the spindle correction wheel to a stop, in a second step. When the user releases the manual actuator, the return spring of the corrector disengages the corrector from the teeth of the spindle correction wheel in a third step, and returns the corrector and its manual actuator to a stop in the rest 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 result in breakage of the spindle correction wheel teeth and / or other damage within the mechanism.

[0007] To overcome this drawback, it was 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 over the other. Thus, in the event of simultaneous actuation of the two manual corrector actuators, such a mechanism prioritizes either the advancement of the local time hand by one hour, or the backward movement of the local time hand by one hour depending on the direction of installation of the safety lock in the mechanism. Summary of the invention

[0008] The aim of the invention is to secure a correction mechanism comprising two opposing correctors acting on the same mechanism, and more precisely on the same correction wheel, to avoid breakage when the user presses the two correction pushers at the 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 particular manual corrector actuator, so that the only consequence in the event of simultaneous actuation of the two manual corrector actuators is the absence of any correction, unlike the devices of the prior art.

[0010] 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.

[0011] To this end, the invention relates to a device for manually controlling a mechanism for a timepiece, comprising two opposing manual corrector actuators, arranged to be operated by a user and to control the same correction wheel set in opposite direction movements, each of the two manual corrector actuators setting in motion an associated corrector comprising a beak which is configured to bear on a relief of said correction wheel set and to move said correction wheel set during a complete stroke of said manual corrector actuator under the action of the user, said manual control device comprises an isolation mechanism arranged to prevent action of one of the two manual corrector actuators on said correction wheel set when the other of the two manual corrector actuators is engaged and interacting with said correction wheel set,characterized in that said isolation mechanism comprises an isolator configured to be rotated upon engagement of one of the two manual corrector actuators, to limit the travel of the other of the two opposing manual corrector actuators and to prevent access of its associated corrector to said correction wheel.,

[0017] The aims, advantages and characteristics of the invention will appear better on reading the detailed description which follows, with reference to the appended drawings, where: there figure 1 represents, schematically and in plan view, and in a rest position, a spindle correction mechanism, comprising a correction wheel which can be driven in two opposite directions by opposing correctors operated by separate manual corrector actuators; figure 2 represents, schematically and in plan view, a detail of the mechanism of the figure 1, and illustrates a first step corresponding to a push applied by the user to a first manual corrector actuator, which drives a first corrector in a clockwise direction, to come to bear at the bottom of the teeth on the correction wheel; figure 3 illustrates, in a similar way to the figure 2 , a second step where the thrust is exerted on the first manual corrector actuator to a stop position, and during which the correction mobile pivots clockwise; the figure 4 illustrates, in a similar way to the figure 2 , the release by the user of the first manual corrector actuator, which, under the action of a first elastic return means constituted by a spring, pivots, as well as the first corrector, in an anti-clockwise direction, to cause its beak to come out of the teeth of the correction wheel; Figure 5 illustrates, in a similar way to the figure 2, the complete release by the first manual corrector actuator, which returns to the stop in the rest position of the figure 1 ; there figure 6 represents, in a schematic manner and in plan view, similar to the figure 1 , a correction mechanism according to the invention, which comprises an isolator, which is a safety lever, making it possible to guarantee that the correctors do not drive the correction wheel at the same time. This safety lever is here, non-limitingly, an annular sector whose distal ends are arranged to cooperate with the manual corrector actuators; figures 7 to 9 represent, in a schematic, partial, and plan view, the correction mechanism of the figure 6 and explain how it works: the figure 7illustrates a first case where the correctors are actuated at the same time. When the manual corrector actuators are actuated at the same time, they come into contact with the safety lever. As each manual corrector actuator exerts an opposite action to the other on the safety lever, their rotation is blocked. The only way to make a correction is to release one of the manual corrector actuators. In this case, the two corrector jaws cannot interact with the correction wheel when they are actuated at the same time; figures 8 and 9 expose a second case, where the correctors are activated one after the other; the figure 8illustrates a first stage, where a first corrector in the left part of the figure, which acts in the direction of an increasing correction, is actuated by the first manual corrector actuator, until the corrector beak comes into contact with a tooth of the teeth of the correction wheel. In this position, the first corrector has driven the safety lever over its maximum travel: the distance between the safety lever and the second manual corrector actuator is very small, and prevents the latter from rotating; figure 9 illustrates the continuation of the movement, if the user continues to push the first manual corrector actuator until the correction wheel is driven. The safety lever remains in the same position and prevents the rotation of the second manual corrector actuator. The two corrector jaws cannot interact with the correction wheel at the same time; the figure 10represents, in a schematic manner and in plan view, similar to the figure 1 , a correction mechanism according to the invention in a rest position without the correctors so as to more precisely visualize the manual corrector actuators; the figure 11 represents, schematically and in plan view, an example of embodiment of a safety lever according to the invention with guidance by pins and oblong grooves; the figure 12 represents, schematically and in plan view, an example of an embodiment of a safety rocker according to the invention which is pivoting; the figure 13 is a block diagram which represents a timepiece comprising a mechanism, a correction wheel of which is arranged to be controlled by such a manual control device comprising two manual corrector actuators.

[0018] In all figures, common elements bear the same reference numbers unless otherwise specified. Detailed description of the invention

[0019] As schematically illustrated in the 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 wheel set 10 in movements in opposite directions.

[0020] The invention is described here in a non-limiting application to the case of a spindle correction mechanism, illustrated by the figure 1 , comprising two antagonistic manual corrector actuators 30, 50, which are here more particularly control pushers, which tend to rotate the correction wheel 10, which is here a spindle correction wheel, in two opposite directions (clockwise and anti-clockwise).

[0021] A first manual corrector actuator 30 is directly operable by a user in a pushing action in a first direction A. The first manual corrector actuator 30 is pivotally mounted around a first articulation pin 31 driven into 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 articulation pin 31.

[0022] The manual control device 100 also comprises a first corrector 20 articulated relative to the first manual corrector actuator 30. For this purpose, the first corrector 20 comprises a first oblong 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.

[0023] The first oblong groove 23 is configured to guide the movement of the first corrector when the first manual corrector actuator 30 pivots, according to a rotational and translational movement.

[0024] The first manual corrector actuator 30 comprises a first actuating stud 32, for example driven into the body of the first manual corrector 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.

[0025] The cooperation of the first oblong groove 23 and the first articulation pin 31 limits the relative travel between the first manual corrector actuator 30 and the first corrector 20.

[0026] The first manual corrector actuator 30 tends to be pushed back, directly or indirectly, in a second direction B opposite to the first direction A, towards an inactive rest position by a first elastic return means 22, here non-limitingly constituted by a spring.

[0027] 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, in a second direction B opposite to the first direction A, towards an inactive rest position, both the first corrector 20 and the first manual corrector actuator 30.

[0028] It is also envisaged according to an alternative embodiment that the first elastic return means 22 is 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.

[0029] The first corrector 20 comprises a first corrector beak 29 which is arranged to cooperate with a relief of the correction wheel set 10, here formed by a spindle correction wheel. The relief of the correction wheel set 10 is for example a tooth 11 of the teeth of the correction wheel set 10. The first actuating stud 32 can also, advantageously, be arranged to constitute a stop limiting the angular travel of the first corrector 20.

[0030] According to an alternative embodiment, the correction wheel 10 could be constituted by a correction star, or other. In this case, the first beak 29 is then arranged to cooperate with a branch, an arm, a lug, or other, which the correction wheel 10 in question comprises. The correction wheel 10 is conventionally held in position by a correction wheel jumper 60 subjected to the action of a jumper spring 63 bearing on a jumper pin 62.

[0031] Similarly, the manual control device 100 comprises a second manual corrector actuator 50 which is directly operable by a user in a pushing action in a third direction C. The second manual corrector actuator 50 is pivotally mounted around a second articulation 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 articulation pin 51.

[0032] The manual control device 100 also comprises a second corrector 40 articulated relative to the second manual corrector actuator 50. For this purpose, the second corrector 40 comprises a second oblong guide groove 43 configured to cooperate with the second articulation pin 51, so as to allow the articulation of the second corrector 40 relative to the second manual corrector actuator 50.

[0033] The second oblong groove 43 is configured to guide the movement of the second corrector 40 during the pivoting of the second manual corrector actuator 50, according to a rotational and translational movement.

[0034] The second manual corrector actuator 50 comprises a second actuating stud 52, for example driven into the body of the second manual corrector 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.

[0035] The cooperation of the second oblong 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, in a fourth direction D opposite to the second direction C, towards an inactive rest position by a second elastic return means 42, here not limited to a spring.

[0036] In the illustrated embodiment, the second elastic return means 42 bears 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, 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.

[0037] It is also envisaged according to an alternative embodiment that the second elastic return means 42 is 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.

[0038] This second corrector 40 comprises a second corrector beak 49 which is arranged to cooperate with a relief of the correction wheel set 10, for example a tooth 11 of the teeth of the correction wheel set 10. The second actuating stud 52 can also, advantageously, be arranged to constitute a stop for limiting the angular travel of the second corrector 40.

[0039] There figure 2 illustrates more particularly a first step corresponding to a push applied by the user on the first manual corrector actuator 30 in the first direction A. This push drives the first corrector 20 in rotation, which pivots in the direction SH, and comes to bear at the bottom of the teeth on the correction wheel set 10. In the representation illustrated in figure 2 , the SH direction corresponds to the clockwise direction.

[0040] There figure 3illustrates more particularly a second step occurring when the first corrector 20 comes to bear at the bottom of the teeth on the correction wheel set 10. In this second step, the thrust is exerted so as to move, in a substantially rectilinear manner, the first corrector 20 to a stop position of the first manual corrector actuator 30, and during which the movement of the first corrector 20 initiates a pivoting of the correction wheel set 10 in the direction SH, which is the clockwise direction in our illustrated embodiment.

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

[0042] 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 correction wheel 10 in a direction opposite to the rotation of the first corrector 20.

[0043] There figure 4 illustrates a third step consisting of the release by the user of the first manual corrector actuator 30, which, under the action of the first elastic return means 22, pivots, as does the first corrector 20 in a second direction SAH, corresponding in our exemplary embodiment to the counterclockwise direction, to cause the first beak 29 to come out of the toothing of the correction wheel 10.

[0044] There Figure 5 illustrates a fourth step corresponding to the complete release of the first manual corrector actuator 30 and the repositioning of the first manual corrector actuator 30, which returns to a stop in a rest position.

[0045] The operation of the second manual corrector actuator 50 and its associated second corrector 40 is similar to the operation of the first manual corrector actuator 30 and the first corrector 20, as described with reference to figures 2 to 5 The embodiment variants 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.

[0046] Advantageously, the two correctors 20, 50 are antagonistic correctors which operate in the same way, and which act on the same correction mobile 10.

[0047] Advantageously, the two correctors 20, 50 act symmetrically on the same correction wheel 10.

[0048] Advantageously, the manual control device 100 further comprises means for neutralizing two simultaneous opposing corrections.

[0049] 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 correction wheel set 10 when the other of the opposing manual corrector actuators 30, 50 is in interaction with the correction wheel set 10.

[0050] 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 manual corrector actuator 30, 50 in question to the correction wheel set 10. And each manual corrector actuator 30, 50 is articulated with a corrector 20, 40, which comprises a beak 29, 49, which is arranged to bear on a relief of the correction wheel set 10 to move it during a complete stroke of the manual corrector actuator 30, 50, under the action of the user.

[0051] The isolation mechanism may comprise an isolator 70, which is arranged to be driven during a movement of one of the manual corrector actuators 30, 50, and to limit the travel of the other of the manual corrector actuators 50, 30, and thus prevent access of its associated corrector 40, 20 to the correction wheel set 10.

[0052] Advantageously, the isolator 70 is driven in rotation during a movement of one of the manual corrector actuators 30, 50.

[0053] In a first embodiment, the insulator 70 is monolithic.

[0054] In a second variant, the insulator 70 is in several parts articulated relative to each other.

[0055] In yet a third variant, the insulator 70 is in several parts, which are arranged to come into contact with one another during an action by a user on one of the manual corrector actuators 30, 50.

[0056] Such an insulator 70 is mounted to rotate about an axis perpendicular to the plate 1, and forms a safety lever making it possible to guarantee that the correctors 20, 40 do not drive the correction wheel 10 at the same time, for example the spindle correction wheel in our non-limiting example of application.

[0057] 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 prior art. Thus, the manual control device 100 according to the invention makes it possible to prioritize 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 advance or recoil corrector during the design.

[0058] The insulator 70 is shown in its entirety more particularly at figure 6 .

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

[0060] 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 corrector actuators 30, 50.

[0061] The two opposite ends of the insulator 70 have an identical shape and perform the same function.

[0062] Each manual corrector actuator 30, 50 further comprises several support profiles making it possible to interact with the isolator 70, and more particularly with the stop fingers 71, 72, depending on the actions of the user.

[0063] 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 finger 71, 72 of the isolator 70.

[0064] Each manual corrector actuator 30, 50 comprises a second support profile 36, 56 configured to form an escape profile, or a sliding profile, on which the stop finger 71, 72 of the isolator 70 slides, so as to allow at least partial rotation of a manual corrector actuator 30, 50 when the opposing manual corrector actuator 30, 50 is not actuated simultaneously, as shown more particularly in figures 8 to 9 .

[0065] When the user performs maneuvers on the manual corrector actuators 30, 50, two cases may arise.

[0066] In the first case, illustrated by the figure 7 , the manual corrector actuators 30, 50 are actuated simultaneously by the user. When the manual corrector actuators 30 and 50 are actuated simultaneously, they simultaneously come into contact with the stop fingers 71, 72 of the insulator 70, at the first support profile 37, 57. Thus, the first support profiles 37, 57 are simultaneously pressed against a stop finger 71, 72 of the insulator 70. As each manual corrector actuator 30, 50 exerts an opposite and identical action to the other on the insulator 70, which can rotate, 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 carry out a correction is to release one of the manual corrector actuators 30, 50 to allow the isolator 70 to switch.

[0068] Thus, the isolation mechanism makes it possible to prevent the two corrector nozzles 29 and 49 from interacting with the correction wheel 10 when they are activated at the same time by the user, via the manual corrector actuators 30, 50.

[0069] Advantageously, the stop fingers 71, 72 have a first identical shape and the first support profiles 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.

[0070] In the second case, as seen on the figure 8 , the user operates only one of the 30, 50 manual corrector actuators at a time.

[0071] In the example embodiment illustrated in the 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 clockwise correction, until the corrector beak 29 comes into contact with a tooth 11 of the teeth of the correction wheel 10.

[0072] The rotation of the manual corrector actuator 30 causes the first support profile 37 to come into contact with the first finger 71 of the insulator, then the rotation of the insulator 70 over its maximum travel.

[0073] Advantageously, the support profiles 37, 36 of the manual corrector actuator 30 are configured so that the maximum stroke of the isolator 70 is reached before the corrector beak 29 comes into contact with the teeth of the correction wheel 10.

[0074] 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 rotation of the latter and of the second correction 40 and therefore actuation of the second manual corrector actuator 50 once the first manual corrector actuator 30 is engaged. A slight play may be possible.

[0075] If the user continues to push the first manual corrector actuator 30 to the stop, as seen in the figure 9, this action drives the correction wheel clockwise. The safety lever 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 isolator 70 acting as a safety lever, the two corrector jaws 29 and 49 cannot interact with the correction wheel 10 at the same time, and no corrector is prioritized 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 to free up space opposite the fingers 71, 72 of the insulator 70, thus allowing the insulator 70 to be able to tilt and reach its maximum travel.

[0077] In a variant illustrated in the 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.

[0078] 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.

[0079] According to another variant illustrated in the figure 12 , the insulator 70 is pivotally mounted around an axis 174 mounted on the plate 1 carrying the manual control device 100.

[0080] In an alternative embodiment, the isolator 70 and the manual corrector actuators 30, 50 are coplanar in the mechanism 500.

[0081] In an alternative embodiment, the isolator 70 and the manual corrector actuators 30, 50 may be positioned in different planes of the mechanism 500 so as to facilitate the integration of the control device 100.

[0082] In an alternative 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.

[0083] In an alternative embodiment, the isolator 70 can cooperate with manual corrector actuators 30, 50 positioned in two different and parallel planes of the mechanism 500.

[0084] The isolator 70 may also be used to initiate one or more additional functions upon switching of the isolator 70. In particular, as illustrated in figures 1 And 6, the insulator 70 may comprise a clutch pin 74 integral with the movements of the insulator 70. This clutch pin 74 is notably arranged to, during the movement of the insulator 70 initiated during a correction, move an additional mobile, for example a clutch mobile, move a lever provided with an idler pinion, engage the correction mechanism with the hand of the timepiece, or even disengage it.

[0085] Each manual corrector actuator 30, 50 comprises a limiting member for limiting the angular travel. The manual control device 100 according to the invention has been shown with reference to the figure 10without the correctors 20, 40 described previously for better visibility. More particularly, the limiting member for limiting the angular travel is formed by a limiting groove 39, 59 provided 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 limiting groove 39, 59 cooperates with the limiting pin 208, 408 in the following manner: in the rest position, under the influence of the first elastic return means 22 or the second elastic return means 42, the limiting groove 39, 59 bears on the limiting pin 208, 408 at a first end of the limiting groove 39, 59.The maximum rotational travel of the manual corrector actuator 30, 50 is defined by the second end of the limiting groove 39, 59 abutting against the limiting pin 208, 408 under the thrust initiated by the user.

[0086] 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 particularly, the manual corrector actuators 30, 50 are actuated by means of pushers provided in the caseband (not shown) of the timepiece 1000.

[0088] The invention also relates to a timepiece 1000, comprising at least one mechanism 500, of which at least one correction wheel set 10 is arranged to be controlled at least by such a manual control device 100.
