Definitions

  • the invention relates to a watch counting device.
  • the invention also relates to a watch movement comprising such a counting device.
  • the invention also relates to a timepiece comprising such a watch movement or such a counting device.
  • the invention finally relates to a method of operating such a counting device or such a watch movement or such a timepiece.
  • the document EP1777598 discloses a programmable countdown mechanism which has a counting device. This construction is equipped with a first control for returning the countdown to the start position, a second “on/off” control, a control rod and an additional control member. The countdown can be programmed by the control rod as long as the initial position return control is held in the pressed position by the additional control member.
  • the document EP2453322 describes a chronograph movement comprising two conventional chronograph controls, and a correction mechanism provided with a control rod.
  • a chronograph movement comprising two conventional chronograph controls, and a correction mechanism provided with a control rod.
  • the control rod found in a position different from that corresponding to a first position, one of the two chronograph commands allows the correction of a quantity linked to time instead of acting on the chronograph.
  • this solution uses the same command for, in a first position of the control rod, the actuation of the chronograph and, in another position of the control rod, different from the first position, the correction of another quantity linked to time.
  • the solution proposed in the document EP2955590 discloses a single-pusher chronograph (three-time) equipped with a so-called “flyback” function.
  • the chronograph and the “flight return” or “flyback” are controlled by a single control in the form of a rod capable of being actuated in translation and rotation.
  • This rod serves in particular as a pusher for controlling the chronograph and “flight return”. Rotating this rod makes it possible to switch the pusher function so as to control either the chronograph or the “flight return”.
  • the aim of the invention is to provide a watch movement making it possible to improve the watchmaking devices known from the prior art.
  • the invention proposes a watch movement having a countdown mechanism whose use is practical and ergonomic.
  • a counting device or a watch movement is defined by claim 12.
  • Embodiments of the counting device or the watch movement are defined by claims 13 and 14.
  • a timepiece is defined by claim 15.
  • the timepiece 200 is for example a watch, in particular a wristwatch.
  • the timepiece 200 comprises a watch movement 100, intended to be mounted in a case or a timepiece box in order to protect it from the external environment.
  • the watch movement 100 may be a mechanical movement, in particular an automatic movement, or a hybrid movement, or an electronic movement.
  • the watch movement is a mechanical watch movement.
  • the watch movement includes a control rod 10, which in particular allows the time of the watch movement to be set.
  • This watch movement is equipped with a counting device 90.
  • the counting device provides a first watchmaking function.
  • the first watch function is for example a counting of time and a display of the counted time, more particularly a counting of time and a display of the counted time.
  • the counting device is for example of the countdown type for a predetermined programmable or adjustable duration.
  • the counting device can be a module intended to be attached to a basic movement or a device incorporated within the basic movement.
  • the counting device comprises a control device provided with a first and a second control members C1, C2, in particular pushers. These control members (or controls) are for example arranged respectively at 4 o'clock and 2 o'clock.
  • first and second mobiles are arranged in the center of the watch movement.
  • the seconds hand 22a can cooperate with a first limb, in particular a limb extended over 360°, allowing a display of 60 seconds.
  • the minute hand 44a can cooperate with a second limb, in particular a limb extended over approximately 300°, allowing for example a “retrograde” type display, indicating for example a maximum duration of 10 minutes.
  • the first command C1 allows a return to the starting position of the mobiles 22, 44, in particular allows the first and second counter mobiles to be returned to their initial position or reset, once the counting device has stopped. The mobiles and the hands which are attached to them are thus returned to an initial display state.
  • the first command C1 for returning to the starting position also allows a correction function for the first and second mobile counters, in particular of the "near minute setting" type (explained below), when the counting is running or activated.
  • a sequencing of the configurations and functions of the watch movement is illustrated on the figure 2 according to the different actions carried out on the control device.
  • the correction function F1 is implemented by activating the first command C1 when the counting device is in the E1 operating configuration.
  • This function allows the preferably instantaneous return to the starting position (“0”) of the seconds mobile 22 and the hand 22a while the counting device is in operating configuration E1.
  • the minute mobile 44 and its hand 44a are, for their part, not returned to their starting position but to the whole minute closest to the time being counted. For example, if there are 2 minutes and 18 seconds left to count down, an action on the first command C1 allows the hands of the counting device to be repositioned “on the fly” so that they display 2 minutes and 0 seconds. For example, if there are 2 minutes and 48 seconds left to count down, an action on the first command C1 allows the needles of the counting device to be repositioned “on the fly” so that they display 3 minutes and 0 seconds.
  • the first watch function is a timing function, in particular a countdown function, displaying first information, in particular minute information, and second information, notably second information.
  • an action, in particular a pressing action, on the first command C1 while the counting device is in an activated state causes a return to the initial position, in particular a return to zero, from the display of the second information and a setting to the entire information closest to the display of the first information.
  • this function allows for example to synchronize "on the fly” the counting device with a reference countdown, as is for example necessary upstream or during the start of a regatta.
  • This function F1 is advantageous, but not essential for the operation of the counting device. As a result, the first command C1 could simply be inoperative in the counting device operating configuration E1.
  • the adjustment or programming function F2 is possible by activating the first command C1 when the counting device is in configuration E3 for returning to the starting position, that is to say when the counting device has been reset, i.e. when the counting device indicates the initial counting time.
  • each action on the first command C1 makes it possible to move, according to a predefined step, the mobile 44 of the minutes and, consequently, makes it possible to configure the number of minutes to be counted down by the hand 44a.
  • an action on the first command C1 allows you to go from a configuration of a time of 1 minute to count down to a configuration of a time of 2 minutes to count down, and so on.
  • an action on the first command C1 while the counting device is in a configuration of a time of 10 minutes to count down brings the minute hand 44a to a configuration of a time of 0 minutes to count down.
  • the counting device counts down the programmed counting time.
  • the control cam 21 is in an on position P1.
  • the control cam 21 is in a stop position P2.
  • the counting device finds itself in its previously programmed starting position.
  • the arrangement of the control cam 21 is unchanged compared to the stop configuration E2.
  • the counting device therefore remains stopped or deactivated in this E3 configuration. In other words, in configuration E3 the counting device is deactivated and returned to the initial position.
  • the first seconds mobile 22 is driven by a finishing train of a basic movement not shown, via a clutch not shown.
  • the seconds mobile 22 and its seconds hand 22a are disengaged from the finishing train by the clutch, and are held in position, for example thanks to friction, so as to display the measured time, in particular the counted time.
  • the seconds mobile 22 is equipped with a heart not shown for returning it to the starting position or initial position.
  • the unidirectional connection mobile 23 allows, under certain conditions (in particular when returning the counting device to the starting position, or when "setting the close minute"), a disengagement between the minute mobile 44 and the mobile 22 seconds.
  • Mobile 23 more particularly visible on the Figure 3 , is equipped with a wheel 23a secured to a star 23b. Wheel 23a is kinematically linked to mobile 22 for seconds.
  • the star 23b is intended to cooperate with a pawl 23c ensuring a unidirectional connection fulfilling the disengagement function.
  • the pawl 23c is assembled on a flange 23d secured in rotation to a wheel 40a and a star 40b of the programming mobile 40.
  • this unidirectional connection mobile 23 makes it possible to put the needles 22a and 44a respectively of the mobiles 22 and 44 back into position independently.
  • Wheel 40a is linked to mobile 41 for returning to the starting position. More particularly, the wheel 40a meshes with a wheel 41a secured in rotation to a cam 41b.
  • the function of the mobile 41 is to allow the minutes to be returned to the starting position of the mobile 44, under the action of a hammer 32 for returning the minutes to the starting position. This hammer will be described in more detail below.
  • the star 40b of the programming mobile 40 is, just like the wheel 40a, capable of being driven by the unidirectional link mobile 23.
  • the star 40b is intended to cooperate with a pawl 40c arranged on a wheel 40d linked to the minute mobile 44 via the cam mobile 42.
  • the programming mobile 40 makes it possible to program the starting position of the mobile 44 minutes before starting the countdown.
  • the conformation of the star 40b, as well as that of the pawl 40c allow the wheel 40a and the wheel 40d, respectively linked to the mobile 41 for returning to the starting position and to the mobile 44 for the minutes, to adopt several relative angular positions .
  • Each of these positions corresponds to a programmable duration of the countdown extending for example between 0 and 10 minutes and which can for example take all integer values between 0 and 10.
  • the cam mobile 42 comprises a wheel 42a arranged at the interface of the wheel 40d and the minute mobile 44.
  • the wheel 42a is integral with a cam 42b which has a spiral shape.
  • a rocker 43 elastically returned by an elastic return element 43a, is preferably provided with a roller 43b which cooperates with the cam 42b. This cooperation allows the mobile 42 to block the rotation of the mobile 44 of the minutes once the time counted by the countdown is reached.
  • E1 operating configuration when the programmed duration has been counted down, the hand 44a attached to the minutes mobile is at 0 minutes and remains in this position, until the counting device is back in position. E3 configuration for returning to starting position.
  • the incrementing mobile 45 is equipped with a star 45b secured to a wheel 45a engaged with the minute mobile 44.
  • the star 45b can be actuated by the control device so that the user can modify the relative angular position of the star 40b and the pawl 40c of the programming mobile 40 and therefore the starting position of the hand 44a of mobile 44 for minutes. It is therefore through this mobile 45 that the programming function F2 is carried out.
  • the first command C1 makes it possible to activate the rocker 30 assembled on a frame 50 of the counting device or the watch movement and pivoted around an axis A30.
  • the rocker 30 is elastically returned to the initial position by an element not shown.
  • the pawl 31 provided with a nose 31c is arranged.
  • This pawl 31 can pivot relative to the rocker 30 around an axis A31.
  • Its nozzle 31c is capable of cooperating with teeth 45c of the star 45b of the incrementing mobile 45, when the counting device is in configuration E3 for returning to the starting position.
  • the pawl 31 is more particularly elastically recalled by an elastic element 31a so that it tends to cooperate with the star 45b.
  • a functional part 30b is capable of cooperating with a first portion 32b of the hammer 32 when the counting device is in stop configuration E2.
  • the hammer 32 is pivotally mounted relative to the frame 50 around an axis A32.
  • One end of the hammer 32 is intended to cooperate with the cam 41b of the mobile 41, preferably via a pivoting roller 32d.
  • An elastic return element 32a cooperates with the hammer 32 so as to exert a torque on the latter tending to place the roller 32d out of reach of the cam 41b.
  • the hammer 32 comprises a second portion 32c capable of cooperating with the control cam 21 when the counting device is in the running configuration E1 or in the stopping configuration E2.
  • the portion 32c is also capable of cooperating with a portion 33c of a locking flip-flop 33, when the counting device is in configuration E3 for returning to the starting position. In this last configuration, the hammer 32 is blocked in the hollow of the cam 41b by the rocker 33.
  • the rocker 33 is pivotally mounted relative to the frame 50 around an axis A33.
  • its angular position facing the frame 50 is defined by the cooperation of its portion 33c with the portion 32c of the hammer 32, as well as by the cooperation of another portion 33d of the rocker 33 with the control cam 21.
  • the rocker 33 is also provided with a portion 33b intended to cooperate with a functional part 31b of the pawl 31, when the counting device is not in configuration E3 for returning to the starting position, so as to position the nozzle 31c outside range of the teeth 45c of the incrementing mobile 45. In other words, with the exception of this last configuration, the pawl 31 is inoperative.
  • An elastic return element 33a allows the elastic return of the rocker 33 so that the portion 33d tends to cooperate with the control cam 21 and so that the pawl 31 tends to cooperate with the incrementing mobile 45.
  • the flip-flop 33 then performs two functions depending on the configuration of the counting device.
  • This flip-flop 33 advantageously makes it possible to modify the functionality of the command C1 between the configurations E1, E2 and the configuration E3.
  • the rocker 33 keeps the pawl 31 out of reach of the incrementing mobile and allows the hammer 32 to cooperate with the control cam 21. Programming the countdown is then not possible.
  • the flip-flop 30 allows the return to the starting position when the counting device is in configuration E2, and allows the “near minute setting” function F1 when the counting device is in configuration E1.
  • FIG. 4 illustrates the counting device in the operating configuration E1, in particular at the very beginning of activation of the device.
  • the counting device begins to count down a previously programmed countdown duration.
  • the control cam 21 has just been positioned by the rocker 20 in an on position P1. In this position, the control cam 21 positions the rocker 33 so as to keep the pawl 31 out of reach of the incrementing mobile 45, and the functional part 30b of the rocker 30 out of reach of the hammer 32.
  • FIG. 5 illustrates a position of the counting device in which the programmed duration is counted down, in other words an operating configuration E1 of the counting device.
  • the configuration of the counting device is unchanged with respect to the Figure 4 . Only the mobiles 22 and 44 and their respective needle 22a, 44a are moved relative to the figure 4 . In fact, the second wheel 22 is driven by the finishing gear. The minute wheel 44 is also driven by the finishing train, but via the unidirectional link wheel 23 as mentioned above.
  • the counting device By activating the second command C2 in the E1 on configuration, the counting device switches to the E2 off configuration.
  • the control cam 21 has been positioned in a stop position P2 by rocker 20 of control C2. This configuration is illustrated on the Figure 6 .
  • the countdown of the duration stops following the disengagement (not illustrated) of the mobile 22 of the seconds. The entire minute counting mechanism is therefore also stopped.
  • the portion 32c of the hammer 32 here cooperates with one of the columns of the control cam 21 so as to position the hammer 32 so that it can be actuated by the rocker 30 of the control C1. More particularly, the portion 32b of the hammer is located here opposite a pin arranged on the functional part 30b of the rocker 30.
  • the portion 32c also makes it possible to maintain the rocker 33 by its portion 33c in a position allowing the pawl 31 to be placed out of reach of the incrementing mobile 45, as in configuration E1.
  • FIG. 7 illustrates the device in configuration E3 for returning to the starting position following actuation of command C1 from stop configuration E2.
  • the first command C1 is held down. This makes it possible to better illustrate the position of the different elements of the control device when returning to the starting position.
  • the rocker 30 returns to its initial position after releasing the command C1.
  • the second and minute mobiles 22, 44 have been repositioned to their respective starting or initial positions.
  • the portion 32b of the hammer 32 has been positioned opposite the functional part 30b of the rocker 30, action on the latter allows the hammer 32 to be driven until it reaches the hollow of the spiral cam 41b.
  • the mobile 41 thus returns to the starting position, driving with it the minute mobile 44 via the programming mobile 40 and the cam mobile 42.
  • the minute counting gear is advantageously disengaged from the second wheel 22 by the unidirectional link wheel 23, as seen previously.
  • the lever 33 is no longer retained by the portion 32c of the hammer and, constrained by its elastic return element 33a, tilts so as to release the pawl 31 so that it can cooperate with the incrementing mobile 45. More particularly, the portion 33d of the rocker is positioned between two columns of the control cam 21. The portion 33b releases the functional part 31b of the pawl 31 which is pushed back by its elastic return element 31a, so that its nose 31c can cooperate with the star 45b of the mobile 45.
  • the rocker 33 is positioned between the two columns of the control cam. In this position, the portion 33c makes it possible to hold the hammer 32, through its portion 32c, in the hollow of the cam 41b. This maintenance makes it possible on the one hand to separate the rocker 30 from the hammer 32 and advantageously to keep the mobile 41 blocked in rotation, which allows programming of the countdown duration. This point is explained in more detail below.
  • the portion 33c can hold the hammer 32, by its portion 32c with a slight play.
  • a slight play is generated between the hammer 32 and the hollow of the cam 41b.

  • FIG 8 illustrates the counting device at rest in configuration E3 for returning to the starting position, that is to say in the reset position.
  • the first command C1 has been released. This configuration can only be reached after the device has been in E2 shutdown configuration.
  • each action on the control C1 makes it possible to rotate the rocker 30 with its pawl 31 so as to advance the star 45b by one step.
  • This programming action is for example illustrated in Figure 9 .
  • the mobile 45 When the mobile 45 is incremented by one step, it carries with it the minute mobile 44 which moves to the next minute, as well as the cam mobile 42 and the wheel 40d of the programming mobile 40.
  • the star 40b kinematically linked to the wheel 40a and to the mobile 41 for returning to the starting position, is advantageously blocked in rotation by the cooperation of the hammer 32 with the latter. This blocking allows the pawl 40c and the wheel 40d to be arranged in a new angular position with respect to the star 40b. Consequently, a new relative angular position of the minute mobile 44 relative to the starting position of the mobile 41 can be adopted. This is how a new countdown duration is programmed.
  • the minute mobile 44 can thus scan indefinitely the entire programmable range, in this case from 0 to 10 minutes.

  • the sequence can thus be 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 0, 1, 2...
  • the adjustment action is an incremental and/or sequential action .
  • FIG. 11 illustrates the counting device in E1 operating configuration at the end of a programmed countdown.
  • the minute mobile 44 is therefore stopped at 0 minutes while the second mobile 22 continues to rotate.
  • the mobile is more particularly blocked by the roller 43b arriving at the hollow of the spiral cam 42b of the mobile 42.

  • the rocker 30 has no effect on the mobiles 41, 45 for returning to the starting position and incrementing.
  • it makes it possible to instantly position the mobile 22 and the seconds hand 22a in a starting position thanks to an action on a dedicated starting position reset heart not shown .
  • the minute mobile 44 is kinematically linked to the second mobile 22, returning the latter to the starting position causes a repositioning of the mobile 44 and the minute hand 44a to the nearest countdown minute.
  • the presented embodiment is based on a two-pusher mechanism with a two-stroke control cam (column wheel with twice as many teeth as columns).

  • the counting device can be a chronograph device.
  • the adjustment provided by the first command C1 can be used for another function such as, for example, adjusting the duration of a decompression stop for a diver.
  • the first command C1 can also be used for another function different from that taking part in the counting device.
  • the first command C1 can be used for any adjustment of the watch that can be made using a pusher, for example, an incremental adjustment of a calendar, of a jumping hour, etc.
  • the first command C1 can even be used to, for example, arm an energy accumulation device, such as a barrel dedicated to a chronograph train, a striker or alarm barrel, etc.
  • the incrementing mobile may not be part of the counting device and that it could be linked to a kinematic chain not included in the counting device, in connection with a second watchmaking function.
  • a first action on the first command C1 would cause a return to an initial display state or a reset of a countdown, then at least a second action on the first command C1 would cause a cocking of a barrel. bell intended to ring a bell mechanism by unwinding at the end of the countdown.
  • the first action is a first press by a user on the first control C1, in particular a press on a pusher C1
  • the second action is a second press on the first control C1, in particular pressing by a user on pusher C1.
  • the actions of pressing on a pusher preferably include a pressing phase itself, then a phase of releasing the pusher in which the pusher is returned to its initial rest position.
  • the pusher may not have any effect on the counting device, that is to say the pusher may not exert any mechanical action modifying a state of a component of the counting device .
  • no action exerted on the counting device is necessary for the second action to have a different consequence from the first action, that is to say no action exerted is necessary to change the configuration or status of the counting device.
  • no action exerted on any user interface (pusher, crown, stem, rotating bezel, lever, bolt, lock, dial) of the timepiece is necessary for the second action to have a different consequence from the first action.
  • no action exerted on the second command C2 is necessary between the first action and the second action.
  • the method is advantageously implemented without action exerted on the timepiece by the user, in particular without action exerted on a user interface of the timepiece by the user, between the first action and the second action.
  • the first watchmaking function and the second watchmaking function are one and the same watchmaking function.
  • the first function is a timing function, in particular a countdown function.
  • any second action on the first command C1, while the first watch function is in an initial state causes an adjustment action of the second watch function.
  • third actions in particular third pressing actions, on the second control C2 sequentially cause activations and deactivations of the counting device and therefore activations and deactivations of the first watch function.
  • the winding action causes a deformation of a spring whose energy is subsequently used to perform the second watchmaking function.
  • the proposed solutions allow the programming of the countdown using a return to starting position or reset command.
  • these solutions offer particular sequencing of the control, which allows programming of the counting device after the display of the latter has been returned to the starting position or reset. More particularly, once the counting device has been reset, the command allows programming in increments of the number of minutes to be counted down for the next countdown, without the user needing to activate another command or interface means to activate the programming function.
