Description

Technical field of the invention

The invention relates to the very specific field of sympathetic clocks and watches.

The invention relates more particularly to a watch and a sympathetic clock forming a sympathetic clockwork assembly, and a method for setting the time of the watch of said sympathetic clockwork assembly.

Technology background

Since 1800, Abraham-Louis Breguet has designed sympathetic clocks for winding, setting the time and adjusting the sympathetic watches dedicated to them, with no other constraint than placing the watch in a dedicated receptacle arranged on the clock.

These three functions are usually done simultaneously at a time defined by the construction of the clock, usually once or twice a day. This is for example the case of the Breguet N°128 clock and the associated N°5009 watch described in the book “The Art of Breguet” by George Daniels. It is the moment when the time setting is triggered that determines the precision of the time setting, which explains the fact that this function was only done once or twice a day for the clocks of the 1800s. , and every two hours for clocks from the 1990s.

It should be noted that sympathetic watches of the state of the art do not have an hour correction in addition to the minute, which forces the user to make a preliminary adjustment with a first setting at coarse time, of the order of more or less fifteen minutes, the clock setting fine time as it passes.

Until now, these only types of functions have always been applied to the rare existing sympathetic pendulums.

Several disadvantages arise from the constructions of the sympathetic clocks of the state of the art, in particular, as long as the watch is placed on the clock, it is set periodically (every two hours, twelve hours or every twenty- four hours), which puts unnecessary strain on the time-setting mechanism. In addition, the operation of the watch is uncertain if it is not removed from the sympathetic clock at a predetermined instant, for example at the end of its time setting.

Also, it is not possible for the user whose watch is stopped to start up his watch at any time. He is then obliged to anticipate this start-up and to carry out a pre-winding of the watch and a pre-adjustment, and to wait for the next passage at the sympathetic time-setting instant.

Summary of the invention

The invention solves the aforementioned drawbacks.

To this end, the present invention relates to a sympathetic watch intended to cooperate with a sympathetic pendulum, comprising a horological movement to which is connected at least one display of a time value, a clutch mechanism making it possible to separate said at least one display and the going train, and a reset mechanism intended to move said at least one watch display into a predetermined reference position.

The watch comprises a first and a second actuator respectively intended to cooperate with a first and a second clock actuator, said first watch actuator capable of occupying at least three distinct successive positions so as to act on the clutch mechanism and on the reset mechanism, said second watch actuator being capable of occupying two extreme positions alternately in order to act on said at least one display by means of a time-setting mechanism, only when the first actuator occupies one of its successive distinct positions.

Thanks to the characteristics of the invention, the watch is capable of being indexed step by step, at any time. The fact that the first actuator occupies distinct positions in each of which it actuates the clutch mechanism, the resonator stop mechanism or the reset mechanism, makes it possible to index the display of a time value reliable and precise, at all times.

In particular embodiments, the invention may also include one or more of the following characteristics, taken separately or in all technically possible combinations.

In particular embodiments, the first actuator is configured to act on the stop mechanism of the resonator of the watch in two distinct successive positions.

The first actuator of the watch is fixed in the case of the watch so as to ensure its watertightness and airtightness.

The transmission lever is arranged in the movement of the watch.

In other words, the displacement of the first actuator transmits, by means of a single lever, forces to the clutch mechanism, to the resonator stop mechanism and to the reset mechanism.

Thus, the movement of the watch has a simple design making it possible in particular to increase its reliability.

In particular embodiments, the first actuator of the watch is configured to act on the clutch mechanism, on the stop mechanism and on the reset mechanism by means of a transmission lever to which it is connected, said transmission lever being configured to simultaneously urge the clutch mechanism and the reset mechanism.

In particular embodiments, the transmission lever extends between a first end of said lever at which it is rotatable and a second end comprising a protrusion by which said transmission lever cooperates with the reset mechanism , with the clutch mechanism and with the stop mechanism.

Alternatively, in another embodiment, the transmission lever can be arranged to slide.

In particular embodiments, the transmission lever is subjected to a return force by a lever spring tending to move it into an initial position in which it drives the reset mechanism into an inactive position, the mechanism of clutch in a clutch position and the stop mechanism in a position in which it releases the resonator.

Thus, when the watch is removed from a receptacle of the clock, the watch can resume normal operation on the one hand, and on the other hand the cooperation between the watch and the clock is interrupted without risk of damaging said watch. or said pendulum.

In particular embodiments, the clutch mechanism comprises two arms forming a clamp, and a friction spring tending to move the going train into engagement with the display train.

The arms are biased by a clutch spring to a clutch position and being configured so that when the first actuator occupies one of its positions, called "first position", they are driven against the clutch spring, into a disengaged position in which they oppose the action of the clutch spring and the friction spring in order to distance said going train from the display train.

In particular embodiments, the arms cooperate with each other at an interface zone through which one of the arms, called "first arm", is able to constrain the other arm, called "second arm", to move towards the clutch position under the effect of the return force generated by the clutch spring, and by which the second arm is capable of transmitting to the first arm a force to which it is submitted by the transmission lever when the first actuator occupies its first position, this force moving said arms into the disengaged position.

In particular embodiments, the reset mechanism comprises at least one heart cam integral in rotation with the display of a time value and at least one hammer arranged to cooperate in support with said at least one heart cam under the action of a hammer spring, so as to occupy an active position and constrain the said core cam in rotation until it rests against its smallest radius, when the first actuator occupies one of its positions, called “first position”, the hammer being configured to be recalled and held in an inactive position by the transmission lever, in which it is moved away from said core cam, when the first actuator occupies another position.

In particular embodiments, the transmission lever is configured so that the protrusion is engaged in a notch of the hammer so that the latter is driven into the active position under the action of the hammer spring and so that the protrusion is extracted from the notch and bears against a side of said hammer in order to drive the latter into the inactive position and to maintain it in this position.

In particular embodiments, the stop mechanism comprises a stop lever subjected to the action of a spring tending to drive the latter in rotation so that said stop lever is arranged to press against a balance wheel of the resonator, the transmission being configured so that the protuberance exerts a force counter to that of the spring applied against said stop lever.

Alternatively, the spring can be configured to tend to move the stop lever lever rocker away from the resonator balance wheel. The transmission lever is then configured so that the protuberance bears against the stop lever rocker so as to exert a force counter to that of the spring applied against said stop lever rocker to bring it to bear against the pendulum.

In particular embodiments, the horological movement of the watch comprises a toothed wheel carried by a minute display wheel set and cooperating with a jumper for holding a minute display in position according to a regular pitch.

Alternatively, the horological movement of the watch may include a minute display mobile, a gear of which includes an appropriate number of teeth to drive the display of the hours by the timer and to cooperate with a jumper to achieve the maintenance in position of the minute display at regular intervals. Thus, the watch movement may not include a dedicated toothed wheel, intended to hold the minutes display in position.

In particular embodiments, the time-setting mechanism may comprise a mobile time-setting component adapted to be acted upon by an impulse from the second actuator of the watch so as to drive a mobile for displaying the minutes in rotation of one step per pulse of the second actuator of the watch and in a single direction of rotation.

According to another object, the present invention relates to a sympathetic clock intended to cooperate with a sympathetic watch as described above.

The clock comprises at least one display of a clock time value driven by a clock movement, and a first and a second actuator intended to cooperate respectively with the first and the second actuator of the watch.

The first actuator of the clock is configured so as to move the first actuator of the watch into its at least three successive distinct positions, and the second actuator of the clock is configured so as to move the second actuator of the watch between its two positions , by a back and forth movement, when the first actuator of the watch occupies one of its positions, the horological movement of the clock comprising at least one control means configured to control or prohibit the movement of the first actuator of the clock.

In particular embodiments, the clockwork movement of the clock comprises a cochlear cam kinematically connected to the display(s) of a time value of the clock, so that its angular position characterizes a value of said display(s) of a value time, and on the periphery of which is arranged to support a first end of a feeler when it occupies an active position, said first end being set back from the cochlear cam when the feeler occupies a rest position.

The watch movement is configured to drive the second actuator of the clock in displacement, during the travel of the feeler between its rest position and its active position, according to a number of back and forth movements representative of the difference between the position reference of the display(s) of a time value of the watch and the time value indicated by the display(s) of a time value of the clock.

In particular embodiments, the feeler comprises, at a second end opposite the first end, a rake arranged to cooperate with a first toothed wheel of a transmission train, said transmission train comprising a second toothed wheel connected to the second actuator of the pendulum so as to move it back and forth when moving the probe from its rest position to its active position.

In particular embodiments, the second toothed wheel meshes with a ratchet driven in rotation by a dedicated energy source and comprising a plurality of triangular teeth against one of which the second actuator of the pendulum is intended to bear so as to be moved back and forth during the rotation of the ratchet.

In particular embodiments, the second toothed wheel is connected to the second actuator of the pendulum by means of a connecting rod-crank mechanism, the connecting rod of which is intended to be integral with the second actuator of the pendulum and of which the crank is integral in rotation of the second toothed wheel.

In particular embodiments, the timepiece movement of the clock comprises a clutch lever adapted to occupy a disengaged position in which it disengages the first toothed wheel and an auxiliary barrel intended to rotate said first toothed wheel and the second gear wheel.

The timepiece movement of the clock further comprises an all-or-nothing device configured to cooperate with the clutch lever so as to drive it into the disengaged position when the feeler reaches its active position, so that said feeler is driven into its rest position under the effect of a feeler return spring.

In particular embodiments, the ratchet is integral with a multiplication train connected to a regulation mechanism so as to regulating the rotation of said ratchet. The regulation mechanism is composed of an escapement and an oscillator.

In particular embodiments, the timepiece movement of the clock comprises a cam driven in rotation by a dedicated energy source and comprising a cam profile against which the first actuator of the clock is arranged to bear, said cam profile comprising successive portions adapted to move said first actuator along at least three distinct positions, so as to define a time cycle of predetermined positions.

In particular embodiments, said at least one control means is configured to block or release the rotation of the cam.

In particular embodiments, the cam is integral with a multiplication train and with a regulation mechanism composed of an escapement and an oscillator so as to regulate the rotation of said cam.

Yet another aspect of the invention relates to a sympathetic clock assembly comprising a sympathetic watch and a sympathetic clock as described previously.

Detailed description of the invention

The invention relates to a sympathetic watch 30, a sympathetic clock 20 and a sympathetic horological assembly 10 formed by said watch and said pendulum, as seen on the figure 1 .

The sympathetic clock 20 comprises at least one display of a time value, such as a display of the hours 21 of the pendulum and a display of the minutes 22 of the pendulum driven by a horological movement of the pendulum so as to indicate a current time. The sympathetic watch 30 comprises, analogously to the sympathetic clock 20, a watch movement to which is connected at least one display of a time value, such as a display of the hours 31 of the watch and a display of the minutes 32 of the watch.

In general, in the present text, the term "display" means any mobile display element known in horology: hand, ring, disc, cursor, flag, etc.

In the remainder of the text, by misuse of language, the sympathetic clock 20 and the sympathetic watch 30 are designated respectively by the terms “pendulum” and “watch”.

The watch movement of the watch 30 comprises, in a conventional manner, at least one barrel 33 for storing energy, for supplying energy to at least one resonator 34, a time-setting mechanism, a gear train display 35 connected to the watch displays and a going train 36.

The watch movement of the watch 30 advantageously includes a stop mechanism 37 of the resonator 34, visible on the figures 2 to 5 . The stop mechanism 37 of the resonator 34 preferably comprises a stop lever 370 arranged to cooperate with an inertial mass, for example constituted by a pendulum, of the resonator 34, to immobilize it or release it.

The stop lever 370 is preferably carried by a stop lever rocker 371 subjected to the stress of a spring (not shown in the figures) tending to drive it in rotation so that said stop lever 370 finds itself resting against the balance of the resonator 34 to immobilize it.

In addition, the watch movement of the watch 30 preferably comprises a clutch mechanism 38 making it possible to separate the display wheel 35 from the finishing wheel 36, as illustrated in the figures 6 and 7 .

The clutch mechanism 38 allows, when it is disengaged, the rotation of the hour 31 and minute 32 displays independently of the going train 36, and when it is engaged the drive of the display train 35, and therefore of said displays, by the going train 36.

As shown in particular by the figures 3 to 5 in an exemplary embodiment, the clutch mechanism 38 comprises two arms 380 and 381 forming a clamp whose function is to ensure engagement and disengagement. The engagement and disengagement positions are defined by the angular spacing of the arms 380 and 381 relative to each other. The clutch mechanism 38 is engaged when the arms 380 and 381 are separated from each other and is disengaged when the arms 380 and 381 are brought together, as shown in the figures. figure 3 And 5 corresponding to figures 6 and 7 .

The two arms 380 and 381 are biased towards the clutch position by a clutch spring 382. In particular, in the preferred embodiment shown in the figures 3 to 5 , the clutch spring 382 applies a return force to one of the arms called "first arm" 380 in the following text, which is configured to transmit this return force to the other arm, called "second arm" 381.

The clutch mechanism 38 also includes a friction spring 383, visible on the figures 6 and 7 , assembled on the going train 36 and tending to move a rim 384 axially movable against the display train 35, so that said finishing train 36 is in engagement by friction of this rim 384 with a disc 385 integral with said display train 35. The arms 380 and 381 are arranged to oppose the action of the friction spring 383 in order to move said finishing gear 36 away from the display gear 35 when the clutch mechanism 38 is disengaged.

The watch movement of the watch 30 also advantageously includes a reset mechanism intended to move each display of the hours 31 and the minutes 32 of the watch 30 into a predetermined reference position, for example at ten o'clock and ten minutes on the picture 3 , or twelve hours and zero minutes on the figure 11 .

To this end, in an example of embodiment represented schematically on the figure 8 and partially visible on the figures 3 to 5 , the reset mechanism comprises a heart cam 390 integral in rotation with the hour display 31, and a hammer 391 arranged to cooperate in abutment with said heart cam 390 under the action of a hammer spring 392, so as to occupy an active position in which it constrains the heart cam 390 in rotation down to its smallest radius.

Alternatively, in another exemplary embodiment not shown in the figures, the reset mechanism comprises a heart cam integral with the hours display and a heart cam integral with the display of the minutes display 32, and comprises two hammers arranged to cooperate respectively in support with each of said core cams, under the action of dedicated springs.

In the exemplary embodiment represented schematically in the figure 8 , the minutes display 32 is driven towards the predetermined reference position by the hours display 31 and by a timer train 311.

The hammer 391 can be recalled and maintained in an inactive position, also called "armed position" in the rest of the text, by an actuator as described in more detail below, so as to move it away from the heart cam 390 when watch 30 indicates the current time, ie when it is in a so-called “normal running” state. In addition, the hammer 391 is kept in the armed position when the watch 30 is set as described in more detail below.

As shown in figure 8 , the horological movement of the watch 30 may also include a toothed wheel 394, such as a star, carried by a minute display mobile and intended to cooperate with a jumper 393 for holding the minute display in position 32 according to a regular pitch when said watch 30 is set on time as described in detail below.

The sympathetic assembly 10 comprises at least one link mechanism between the clock 20 and the watch 30, schematically represented on the figure 2 And 9 , intended to cause the clock 20 and the watch 30 to cooperate mechanically when the latter is deposited in a receptacle of the clock 20, in a transfer position.

According to the invention, this link mechanism comprises at least two separate transmission lines having different functions from each other and intended to transmit a movement of the clock 20 to the watch 30.

Each transmission line is constituted by a watch actuator 30 and by a clock actuator 20, said actuators being capable of cooperating with each other.

In particular, the watch 30 comprises a first and a second actuator 310 and 320 respectively intended to cooperate with a first and a second actuator 210 and 220 of the clock 20.

When the watch 30 is arranged in the receptacle in the transfer position, the first and second actuators 210 and 220 of the clock 20 are intended to cooperate respectively with the first and second actuators 310 and 320 of watch 30 so as to transmit a movement to them, preferably a translational movement.

Preferably, the first and second actuators 310 and 320 of the watch 30 are in the form of pushers as shown by the figures 3 to 5 , 9 And 10 .

In embodiments not shown in the figures, the first and second actuators 310 and 320 of the watch 30 and the first and second actuators 210 and 220 of the clock 20 comprise, at their ends by which they cooperate, magnetic elements or coupled ferromagnets which make it possible to favor the guiding of the transmission of the translational movement.

In the preferred embodiment of the invention, the first actuator 310 of the watch 30 is connected to a transmission lever 39 so that the movement of said first actuator 310 of the watch 30 modifies the angular position of the said transmission lever 39 More specifically, the first actuator 310 is connected to the transmission lever 39 by a pivot arranged between a first end of said lever at which it is rotatable and a second end which is free.

Advantageously, the transmission lever 39 is configured so as to be adapted to cooperate with the hammer 391, with the clutch mechanism 38, with the minute jumper 393 and with the stop lever 370.

More particularly, the transmission lever 39 comprises a protrusion, for example formed by a tenon or a pin 395 arranged at its second end. In the remainder of the text, the excrescence is designated by a pin for reasons of clarity.

The pin 395 is adapted to bear against the stop lever rocker 371 so as to exert a force going against that of the spring applied against said stop lever rocker 371.

Furthermore, depending on the position of the first actuator 310 of the watch 30, the pin 395 is capable of resting against a side of the hammer 391 so as to keep it in the cocked position and is capable of engaging in a notch 396 of said hammer 391 so as to allow it to move into the active position under the action of the hammer spring 392.

In addition, the pin 395 is adapted to bear against one of the arms 381 of the clutch mechanism 38 so as to be able to drive said clutch mechanism 38 into the disengagement position.

In addition, the pin 395 is adapted to bear against one of the sides of the jumper 393 so as to be able, depending on the position of the transmission lever 39, to maintain said jumper 393 in a cocked position, in which it is inactive, or allow it to move into an active position in which it cooperates with the toothed wheel 394, under the action of a jumper spring 3962, by engaging in a notch 3961 of said jumper 396.

More specifically, in the preferred embodiment of the invention shown in the figures 3 to 5 , the pin 395 bears against a side of the second arm 381 and is able, when the transmission lever 39 moves, to cause the movement of the said second arm 381 against the return force of the clutch spring 382 Advantageously, the second arm 381 is configured to cause the first arm 380 to move against the return force of said clutch spring 382.

In particular, as seen on the figures 3 to 5 , the first and the second arm 380 and 381 cooperate with each other at an interface zone by which the first arm 380 constrains the second arm 381 to move towards the clutch position under the effect of the return force generated by the clutch spring 382, and by which the second arm 381 is capable of transmitting a force to the first arm 380 running counter to the return force, under the effect of the movement of pin 395, so as to move said first arm 380 and second arm 381 into the disengaged position.

For example, as shown by the figures 3 to 5 in a general way and in a more detailed and schematic way the figure 11 , the second actuator 320 of the watch 30 can take the form of a corrector stem intended to cooperate with the second actuator 220 of the clock 20.

The time-setting mechanism of the watch 30 may comprise a mobile time-setting component, such as a time-setting rocker 321 formed by a first arm adapted to be acted upon by the corrector stem to move said time-setting rocker 321, and by a second arm whose free end is adapted to drive the minutes display mobile in rotation, for example by one tooth by back and forth movement of the second actuator 320.

The minute display mobile is held in position by the jumper 393, between each movement caused by the actuation of the second actuator 320 and after the time setting of the watch 30.

The clock 20 is intended to set the time of the watch 30, at the request of a user or of the clock 20, by the action of the first and second actuators 210 and 220 on those of said watch 30 as described in the continuation of the text. Setting the time of the watch 30 makes it possible to be able to adjust, for example, the following indications: hours, minutes, dates, days of the week, month, moon phase. In the present text, a time setting is described making it possible to adjust the display of the hours and minutes of the watch 30 step by step.

As described in more detail below, the first actuator 310 of the watch 30 is configured to adopt several successive distinct positions, under the action of the first actuator 210 of the clock 20. In other words, the actuation of the first actuator 310 of the watch 30 by the first actuator 210 of the clock 20 allows the realization of time-setting operations of the displays of the watch 30 in a sequential manner.

In particular, following each actuation of the first actuator 210 of the clock 20 on the first actuator 310 of the watch 30, phases of a process for setting the time of the watch 30 by the clock 20 are successively carried out.

In one of the phases, called the “initial phase”, the watch 30 and the clock 20, and in particular their respective actuators, do not cooperate with each other so that the watch 30 can be freely removed from the receptacle.

During the following phases, called “operational phases”, the first and second actuators 310 and 320 of the watch 30 cooperate respectively with those of the clock 20 so that the actuators of the clock 20 can impart a movement to the actuators of the watch 30 In particular, successive stresses of the first actuator 210 of the clock 20 lead to the sequence of all the operational phases followed by the initial phase, in a cyclical manner.

Each phase corresponds to a specific position of the first actuator 210 of the clock 20, and consequently, of the first actuator 310 of the watch 30.

Below are set out, in a particular embodiment of the invention, the means of the pendulum 20 making it possible to act on the first and second actuators 210 and 220 of the said pendulum 20 so that the latter act respectively on the first and second actuators 310 and 320 of watch 30.

As seen in the schematic representation of the figure 9 , the watch movement of the pendulum 20 may comprise a cochlear cam 230 on the periphery of which is arranged to bear against a first end of a feeler 231 when it occupies an active position. Said first end of said feeler 231 is set back from the cochlea cam 230 when it occupies a rest position in which it is urged by a feeler return spring not shown in the figures. The rest position of feeler 231 corresponds to the reference position of the displays of watch 30 plus a safety delay corresponding to a duration desired offset for setting the time of the watch and to ensure a waiting period, for example of five minutes, for restarting the watch, as described below.

The cochlea cam 230 is kinematically connected to the hour display 21 of the clock 20, so that its angular position characterizes a value of said hour display 21 of the clock 20 and consequently of the current time.

More specifically, the cochlea cam 230 is arranged so as to complete one revolution in twelve hours and has one hundred and forty-four bearings on its circumference. The feeler 231 is then likely to rest in contact with a new bearing every five minutes.

Advantageously, as shown in figure 9 , the watch movement of the clock 20 may comprise a jumping mechanism connecting the hour display 21 to the cochlear cam 230, so as to cause the latter to rotate every 5 minutes.

The sensor 231 is arranged to move in rotation so as to transfer the value of the hour display 21 of the clock 20 to the second actuator 220 of the clock 20. In particular, during its travel between the rest position and the position active, the feeler 231 is configured to allow the movement of the second actuator 220 of the clock 20 over a course representative of the difference between the reference position of the displays of the watch 30 and the current time indicated by the displays of the pendulum 20.

In particular, the sensor 231 is connected to a rake 232 at a second end opposite the first end, by means of an elastic connection 238. The rake 232 is arranged to cooperate with a transmission train configured to drive the second actuator 220 according to the time indicated by the minutes 22 and hours 21 displays of the clock 20. The transmission train is preferably intended to be driven in rotation by a dedicated energy source, preferably by a barrel dedicated, called "auxiliary barrel" 234. It should however be noted that the energy source can alternatively take the form of a weight linked by a cable to a drum, in a way known as such by man of career.

This referencing of the time indicated by the clock 20 is done analogously, with one difference, to that performed by a minute part of a minute repeater mechanism on demand. The difference lies in the fact that in the present invention, the counting is carried out by the stroke of the feeler 231 from its rest position to its active position, that is to say when the feeler 231 moves to the contact of the snail cam 230; whereas for a minute repeater, counting is carried out by the stroke of a minute piece from an active position in which it is in contact with a minute snail, to a rest position.

More specifically still, in an exemplary embodiment of the invention, the transmission train comprises a first toothed wheel 235 meshed with the rake 232, and a second toothed wheel 236 arranged to be able to move the second actuator 220 of the pendulum 20, said first and second toothed wheel 235 and 236 being kinematically connected to each other. Preferably, the first and the second toothed wheel 235 and 236 are carried by the auxiliary barrel 234 and linked kinematically to the second actuator 220, as shown in figure 9 .

The clock movement of the clock 20 further comprises a clutch lever 240 adapted to separate the first and the second toothed wheel 235 and 236 from each other, and more precisely the first toothed wheel 235 and the auxiliary barrel 234 Preferably, the clutch lever 240 is fixed in a rotatable manner on the frame of the pendulum and is configured so as to be, in a clutching position, in engagement with a toothed wheel, called "third toothed wheel". 237, kinematically linked to the toothed wheel 235 by a satellite gear train, and to be, in a disengaged position, disengaged from said third toothed wheel 237.

The second toothed wheel 236 is advantageously meshed with an output mobile, here formed by a ratchet 233 arranged in a rotatable manner and having a plurality of triangular teeth, also called "wolf teeth" by those skilled in the art, against the one of which is arranged to support the second actuator 220 of the pendulum 20. This second actuator 220 of the pendulum 20 takes the form of a control lever in the preferred embodiment of the invention represented on the figure 2 And 9 . This control lever is for example biased towards the ratchet 233 by elastic return means or by gravity, so as to be driven by a back and forth movement during the rotation of the wolf teeth of the ratchet 233.

The second actuator 220 is thus adapted to alternately take two distinct extreme positions during the rotation of the ratchet 233.

The second actuator 220 of the clock 20 transmits a pulse to the second actuator 320 of the watch 30, in order to move it between two extreme positions.

The speed of rotation of the ratchet 233 is advantageously regulated by an exhaust speed regulator known as such by those skilled in the art and similar to that shown in the detail view of the figure 9 for regulating the rotation the cam of the first actuator.

The elastic link 238 is connected to an all-or-nothing device 242 adapted to act on the ratchet 233 and on the clutch lever 240. The elastic link 238 and the all-or-nothing device 242 are configured so that, when the feeler 231 is driven in rotation by the rake 232, under the effect of the auxiliary barrel 234, until it comes into contact with the cochlear cam 230, the elastic connection 238 deforms and stresses the all-or-nothing device 242 so that the latter immobilizes the ratchet 233 and pivots the lever clutch 240 in order to separate the first toothed wheel 235 and the auxiliary barrel 234. In particular, the all-or-nothing device 242 comprises a hook 241 adapted to cooperate with the teeth of the ratchet 233 so as to immobilize the latter.

The clutch lever therefore releases the feeler 231 from the grip of the auxiliary barrel 234, which allows the rake 232 and the feeler 231 to return to their rest positions under the constraint of their return spring (not shown on the figure 9 ).

The displacement of the sensor 231 from its rest position to its active position is triggered by the first actuator 210 of the pendulum 20, by dedicated means not shown in the figures and within the reach of those skilled in the art, when said first actuator 210 occupies a predetermined position as described in more detail in the following text.

In summary, on triggering of the first actuator 210, the feeler 231 is driven in rotation via the rake 232 meshing with the auxiliary barrel 234, as well as the ratchet 233 which imparts a to-and-fro movement to the second actuator 220, and this until the feeler 231 bears against the cochlea cam 230. When the feeler 231 reaches its active position, the ratchet 233 is immobilized and the rake 232 is separated from the auxiliary barrel 234, so that the feeler 231 is driven to its rest position by the feeler return spring

The pendulum 20 may include a cam 211 as shown in the detail view of the figure 9 to cause the movement of the first actuator 210 of the pendulum 20. This cam 211 is different from the ratchet 233 of the second actuator 220 insofar as it has portions of profiles connected by ramps configured to move said first actuator 210 along at least three distinct positions, one after the other, so as to define a time cycle of predetermined positions which follow one another at a defined speed.

In the preferred embodiment of the invention, the first actuator 210 takes the form of a control rod or a control lever as shown in the figures. figure 2 And 9 , and is also urged towards the cam 211 by elastic return means 212, as visible on the figure 9 . Thus, it is understood that the first actuator 210 can be moved in translation or in rotation by the cam 211, depending on the embodiment considered.

It should be noted that, in the exemplary embodiment shown in the detail view of the figure 9 , the cam 211 is intended to pivot counterclockwise, contrary to the general view of the same figure 9 or the cam is intended to pivot clockwise for reasons specific to the construction of the mechanism.

The cam 211 is driven in rotation by a dedicated energy source, such as a weight or a barrel, and is integral with a multiplication train and a regulation mechanism composed of an escapement and an oscillator , so as to regulate its rotation speed, known as such to those skilled in the art and shown in the detail view of the figure 9 .

The pendulum 20 comprises two control means 2130 and 2131 intended to authorize or prohibit the pivoting of the first actuator 210 of the pendulum 20. In other words, the control means 2130 and 2131 are arranged to allow the rotation of the cam 211 and thus the modification of the position of the first actuator 210 of the pendulum 20.

More precisely, the two control means 2130 and 2131 make it possible to authorize or prohibit the rotation of the cam 211 over one revolution. In particular, one of the control means, called "first control means" 2130, makes it possible to start the rotation of the cam 211 and its immobilization, that is to say to start the time-setting process described in detail below, and to complete it. The other control means, called "second control means" 2131 stops the first actuator 210 of the pendulum 20 during the movement of the second actuator 220 followed by the start of the five-minute waiting period to release the first actuator 310 of the clock 20 again.

In the preferred embodiment shown in the figure 9 , each of the first and second control means 2130 and 2131 is formed by a lever intended to bear against the circumference of a control cam 2132 concentric with the cam 211 and integral with the latter. The circumference of the control cam 2132 includes at least one radial notch respectively intended to cooperate with the two control means 2130 and 2131.

The levers both comprise a beak designed to cooperate with the teeth of one of the mobiles of the multiplication gear train to immobilize said gear train.

In particular, when one of the levers cooperates with one of the notches, the beak of said lever presses against one of the mobiles of the regulating gear train in order, by taking advantage of the gear reduction of said gear train, to block its rotation.

Alternatively, it is conceivable that the clock 20 comprises only a single control means in the form of a lever, said lever then comprising two beaks. Furthermore, the control cam 2132 and the cam 211 can form a single one-piece cam.

The first control means 2130 is arranged to be operated by the user.

The second control means 2131 is arranged to be controlled by the clock 20 at the next passage of five minutes following the end of the counting carried out by the feeler 231, by a mechanism linked to the rotation of the minute displays of the clock 20. This is to generate the timeout to release the first actuator 310 of the clock 20.

When the first control means 2130 is operated or piloted, it allows the rotation of the cam 211, and therefore the solicitation of the first actuator 310 of the watch 30 by the first actuator 210 of the clock 20, and consequently the movement of said first actuator 310 of the watch 30 from an initial position to a first position, that is to say the start of a first operational phase. Preferably, this change of position is carried out over a period of about five seconds and the first position is maintained for about five seconds.

A second operational phase then begins in which the first actuator 210 of the clock 20 causes the movement of the first actuator 310 of the watch 30 into a second position. When the first actuator 310 is in this position, the second control means 2131 cooperates with the notch of the control cam 2132 so as to immobilize the cam 211 during the waiting time necessary to perform the function of the second actuator described previously added to the waiting time for the next passage of the clock at the time displayed by the watch, in steps of 5 minutes for example.

At the end of these two waiting times, a third phase is started in which the second control means 2131 is disengaged from the notch of the control cam 2132, which makes it possible to restart the rotation of the cam 211 and thus the actuation of the first actuator 310 of the watch 30 by the first actuator 210 of the clock 20, so that said first actuator 310 of the watch 30 occupies a third position corresponding to the initial position.

Preferably, this change of position is carried out over a period of approximately 0.1 second and the third position is maintained by the cooperation of the first control means 2130 with the notch of the control cam 2132 so as to immobilize the cam 211.

In other words, the two control means 2130 and 2131 are configured to alternately authorize or prohibit the actuation of the first actuator 210 of the clock 20.

The successive operational phases of the method for setting the time of the watch 30 by the clock 20 are described in detail below and are implemented thanks to the change of position of the first actuator 310 of the watch 30 according to the time cycle of predetermined positions.

In the first operational phase following the initial phase, the first actuator 210 of the clock 20 drives the first actuator 310 of the watch 30 into the first position. The watch 30 in this first operational phase is represented on the figure 3 And 11 .

In the preferred embodiment, in order to drive the first actuator 310 of the watch 30 in all of its positions, the first actuator 210 of the clock 20 bears against portions of the profile of the cam 211.

In particular, in the initial phase, the first actuator 210 of the pendulum 20 occupies the initial position in which it bears against a sector 217 of a first portion 2170 of the profile of the cam 211. This first portion 2170 comprises a first ramp 219 defining an increase in cam radius making it possible to drive, from its initial position, the first actuator 310 of watch 30 into its first position at a controlled speed, for example 5 seconds, during the first operational phase.

The first actuator 310 of the watch is driven into its first position when the first actuator 210 of the clock 20 reaches, following its run along the first ramp 219, a second portion 214 of the cam 211.

The first operational phase is carried out when the first actuator 210 of the pendulum 20 is resting against the second portion 214. This second portion 214 is concentric, that is to say whose radius of the cam 211 on the second portion 214 is constant, so as to maintain the first actuator 310 of the watch 30 in the first position over a predefined period, for example 5 seconds. This predefined delay allows the performance of the following functions, during the first operational phase.

The first actuator 310 of the watch 30 is configured so that when it occupies the first position, it requests the reset mechanism so as to move the displays for the hours 31 and the minutes 32 of the watch 30 to their position. reference.

More precisely, when it moves to occupy the first position, the first actuator 310 of the watch 30 drives the transmission lever 39 in rotation until the pin 395 engages in the notch 396 of the hammer 391. This thus allows movement of the hammer 391 into the active position under the action of the hammer spring 392, and consequently the movement of the hour 31 and minute 32 displays to their reference position.

The first actuator 310 of the watch 30 is also configured so that when it occupies the first position, it acts on the clutch mechanism 38 so as to cause the disengagement of the going train 36 and of the display train 35 and causes the stop lever 370 to be driven into a blocking position of the resonator 34 of the watch 30.

In particular, in the preferred embodiment of the invention, the rotation of the transmission lever 39 caused by the displacement of the first actuator 310 of the watch 30 towards its first position drives, through the pin 395, the first and the second arm 380 and 381 in rotation towards each other, against the return force generated by the clutch spring 382, and thus the disengagement of the clutch mechanism 38.

In the preferred embodiment of the invention, when the first actuator 310 of the watch 30 moves to occupy the first position, the rotation of the transmission lever 39 causes the movement of the stop lever rocker 371 under the effect of the force generated by the spring stop lever until the stop lever 370 bears against the pendulum, consequently causing the resonator 34 to stop.

In the second operational phase, following the second portion 214 of the profile of the cam 211, the first actuator 210 of the pendulum 20 is driven bearing against a ramp 216 from a third portion 2150 of the profile of the cam 211 until to reach, within a practically instantaneous time, for example 0.1 second, a sector 215 of said third portion 2150. When it reaches this sector 215, the first actuator 210 of the clock 20 drives the first actuator 310 of the watch 30 in the second position.

The ramp 216 is defined by a decrease in the radial section, representing the radius, of the cam 211 considering the direction of rotation of said cam 211 in the present text. In the second position, the first actuator 310 of the watch 30 is therefore further back with respect to the watch 30 than when it occupies the first position.

The watch 30 in this second operational phase is represented on the figure 4 And 12 .

In this second position, the first actuator 310 of the watch 30 is configured so that it resets the hammer 391, that is to say that it drives the hammer 391 at a distance from the heart cam 390, in its position inactive.

More specifically, in the preferred embodiment of the invention, the pin 395 is forced to withdraw from the notch 396 of the hammer 391 during the movement of the transmission lever 39 caused by the first actuator 310 of the watch 30 when he is dragged to his second position. The pin 395 therefore subsequently rests against the side of the hammer 391, and causes it to rotate against the hammer spring 392.

Advantageously, the resetting of the hammer 391 does not cause any modification of the position of the displays for the hours 31 and the minutes 32 of the watch 30 thanks to the cooperation between the jumper 393 and the toothed wheel 394 carried by the minutes display mobile.

The first actuator 210 of the pendulum 20 is configured so that, when it is driven into its second position, it causes the ratchet 233 to rotate and the feeler 231 to move from its rest position to its active position. , and consequently the actuation of the second actuator 220 of the pendulum 20.

To do this, the first actuator 210 of the clock 20 can for example act via a dedicated mechanism not shown in the figures, on the hook 241, so as to move it back from the ratchet 233 in order to allow its rotation under the stress of the auxiliary barrel 234. The movement of the hook 241 has the effect of pivoting the clutch lever 240 so as to secure in rotation the first and the second toothed wheel 235 and 236 with each other, causing the rotation of the rake 232 under the stress of the auxiliary barrel 234 and thus the pivoting of the feeler 231 from its rest position to its active position.

In other words, during this second operational phase, the second actuator 220 of the clock 20 therefore drives the second actuator 320 of the watch 30 in a back and forth movement between two extreme positions.

Furthermore, the angular travel of the probe 231 corresponds to the number of steps separating the time corresponding to the reference position of the displays of the watch 30, from the current time indicated by the displays of the clock 20.

The second actuator 320 of the watch 30 is arranged to drive, during each of its back and forth movements, the minute display 32 of the watch 30 by a step of a given value via the setting rocker at hour 321, the drive of the minute display 32 causing the movement of the hour display 31.

The value of steps is an integer submultiple of the hour: one minute, two minutes, three minutes, four minutes, five minutes, six minutes, ten minutes, twelve minutes, fifteen minutes, twenty minutes, thirty minutes.

Advantageously, the cochlea cam 230 and the feeler 231 are configured so that the second actuator 220 of the clock 20 drives the second actuator 320 of the watch 30 so as to move the minutes display 32 so that the position of the minutes displays 32 and hours 31 of watch 30 corresponds to that of the displays for minutes 22 and hours 21 of clock 20 plus at least one step.

In other words, during this second phase, the second actuator 320 of the watch 30 is acted upon by the second actuator 220 of the clock 20 so as to drive the hour 31 and minute 32 displays of the watch 30 in successive steps, until 'at a position corresponding to that of the current time plus a predetermined additional number of steps, for example a number of steps corresponding to a value of five minutes.

During this second operational phase, the second control means 2131 is arranged so as to immobilize the cam 211 during the actuation of the second actuator 220 of the clock 20, that is to say during the increased time setting of the watch 30, and during the waiting period, for example of five minutes, at the end of said increased time setting of the watch 30.

The third operational phase is activated, by the second control means 2131 controlled following the immobilization of the second actuator 220 of the clock 20 and by the transition to the next 5 full minutes of the clock 20 as described above. In this third operational phase, the cam 211 is driven in rotation so that the first actuator 210 of the pendulum 20 bears against a fourth portion 218 of the profile of the cam 211 in the form of a ramp so as to drive the first actuator 310 of the watch 30 into its third position, that is to say into its initial position. The cam 211 is immobilized, in this third phase, by the first control means 2130.

The fourth portion 218 defines a decrease in the radial section of the cam 211 considering the direction of rotation of said cam 211. In the third position, the first actuator 310 of the watch 30 is therefore further back with respect to the watch 30 than when it occupies the second position.

The watch 30 in this third operational phase is represented on the figure 5 And 13 .

In this third position, the first actuator 310 of the watch 30 is configured to cause the engagement of the clutch mechanism 38 and the drive of the stop lever 370 into a release position of the resonator 34 of the watch 30. Optionally, the first actuator 310 of watch 30 can be configured to, during this phase, maintain the winding of hammer 391.

More precisely, during the displacement of the first actuator 310 of the watch 30 towards its third position, the rotation of the transmission lever 39 drives, by means of the pin 395, the first and the second arms 380 and 381 in rotation one and the other in opposite directions under the effect of the return force generated by the clutch spring 382.

Moreover, when the first actuator 310 of the watch 30 moves to occupy the third position, the rotation of the transmission lever 39 causes the movement of the stop lever rocker 371 against the force generated by the spring. stop lever until the resonator 34 is released.

In addition, the jumper 393 is configured so that, during the movement of the transmission lever 39 when the first actuator 310 of the watch 30 is driven towards its third position, the pin 395 bears on one of its sides so as to move it away from the toothed wheel 394, which makes it possible to free the rotation of the minute display 32 from watch 30.

In other words, the first actuator 210 of the clock 20 is configured so as to control the first actuator 310 of the watch 30 to start the implementation of the third operational phase, when the current time, that is to say the time indicated by the displays for hours 21 and minutes 22 of the clock 20, corresponds to the time indicated by the displays for hours 31 and minutes 32 of the watch 30.

The third phase corresponds to the initial phase, that is to say a state of the watch 30 in which it is before the start of the first phase with the exception of the displays of the watch 30, which are in phase with those of the clock 20.

Preferably, the transmission lever 39 is subjected to a return force by a lever spring tending to move it into a so-called "initial position" position corresponding to that in which it is when the first actuator 310 of the watch 30 in the third position. This return force is advantageously dimensioned so that the transmission lever 39 is driven into the initial position when the first actuator 310 of the watch 30 is not acted upon by the first actuator 210 of the clock 20, that is to say say when the first actuator 310 of the watch 30 is in the third position.

More particularly, the position of the first and second actuators 310 and 320 of the watch 30 in this third phase corresponds to rest positions in which they are arranged, in particular, when the watch 30 does not cooperate with the clock 20.

It should be noted that the durations of the aforementioned operational phases and of the transitions between each of said phases are proportional to the angular amplitude over which the portions of cam profile 211 and the ramps between said portions extend.

More generally, it should be noted that the modes of implementation and embodiment considered above have been described by way of non-limiting examples, and that other variants are therefore possible.

In particular, the transmission lever 39 can cooperate with each of the two arms 380 and 381, said arms 380 and 381 then being independent of each other and cooperating with a dedicated clutch spring.

Furthermore, one of the arms 380 or 381 or the arms 380 and 381 may comprise an elastic portion so as to constitute the clutch spring. This characteristic advantageously makes it possible to avoid the use of a dedicated clutch spring.

It should also be noted that the transmission lever 39 can be replaced by a column wheel as used in watch movements of the chronograph type.
