  • the mechanism also comprises first and second reset members, each having a bearing surface and intended to be pivotally mounted with reference to the plate between a low position in which each support surface cooperates with the periphery of a reset cam of one of the counters and a high position in which each bearing surface is located at a distance from the corresponding cam.
  • the chronograph mechanism further comprises retaining means for holding each of the reset members in its up position, as well as spring means arranged to rotate the reset members to their respective lower positions in response to an action. of a user to release the retaining means.
  • the main object of the present invention is to simplify the manufacture and assembly of reset members known from the prior art. Additional objects of the present invention are to improve the reliability of devices of the prior art and, in particular, to improve the behavior in time and use, in terms of adjustment.
  • the subject of the present invention is a chronograph mechanism of the type mentioned above, characterized in that the retaining means comprise a first retaining member acting directly on a first of the resetting members and capable of be released in response to the action of the user, and a second retainer acting directly on the second of the reset members in response to a pivoting of the first reset member towards its lower position .
  • the first reset member pivots along a first axis of rotation while the second reset member pivots along a second axis of rotation distinct from the first axis of rotation.
  • the second retaining member is then preferably an isolator capable of pivoting along a third axis of rotation, distinct from the first and second axes of rotation, and having a first free end, arranged to cooperate with a control surface of the first reset member. zero, and a second free end, arranged to cooperate with a bearing surface of the second reset member.
  • the mechanism comprises a rotary control member, which may be a column wheel, arranged to turn stepwise in response to repeated user actions and to have at least first and second different configurations, with reference to the reset members.
  • This control member is then arranged in such a way that it is capable of acting on each of the reset members to rotate them from their respective low positions to their respective high positions by passing from its first configuration to its second configuration.
  • the present invention also relates to a watch mechanism and a timepiece comprising a mechanism of the type just described.
  • FIG. 1 represents a simplified top view of a watch movement comprising a chronograph mechanism according to a preferred embodiment of the present invention, the latter being represented in a first configuration;
  • the figure 2 represents a view similar to that of the figure 1 the chronograph mechanism being shown in a second configuration
  • the figure 3 represents a view similar to that of the figure 1 , the chronograph mechanism being shown in a third configuration.
  • FIGS. 1 to 3 represent simplified plan views, on the dial side, of a part of a movement 1 comprising a chronograph mechanism according to the present invention, respectively in a first, a second and a third configuration in which the chronograph is respectively stopped, in operation and reset.
  • This movement 1 comprises frame elements, including a plate 2, on which are mounted mobile, levers, scales and other watch components, of which only those related to the chronograph mechanism will be described in detail in this presentation.
  • the chronograph mechanism includes chronograph 10, minute 20 and hour 30 counters.
  • Each of these counters comprises a mobile (including a wheel 11, 21, 31 is visible) intended to be driven in connection with a time base (that of the finishing train or a chronograph-specific time base) and is arranged to drive in rotation of the measured time display members (not shown).
  • Each counter also comprises a core cam 12, 22, 32 integral in rotation with the corresponding display member and intended to cooperate with reset members which will be described in detail below.
  • the chronograph mechanism is of the column wheel type 3.
  • the latter can be rotated on itself by a hook 4, integral with a control 5 whose displacements can be controlled, in a conventional manner, from a pusher (not shown).
  • Each press on the pusher causes a rotation of one step of the column wheel 3, making the chronograph function of a stopped state ( figure 1 ) to an active state ( figure 2 ) and vice versa.
  • the alternation of solids (columns) and empty acts on different latches to activate or deactivate functions relating to the measurement of time intervals.
  • the column wheel cooperates in particular with a clutch rocker 6 carrying a clutch return 7 and pivotally mounted on the plate between a first rest position ( figure 1 ) and a second position training ( figure 2 ) of a chronograph train, from a finishing train (not shown), via the chronograph wheel 11 meshing or not with the clutch return.
  • An additional clutch rocker (not shown) may be provided to drive the hours mobile 31, for example from the average wheel, while the minute counter 20 is preferably driven from the seconds counter. , in a conventional way.
  • the column wheel 3 also cooperates with a lever 40, acting on a blocker 41 whose function is, typically, to maintain fixed the angular position of the chronograph wheel 11 when the measurement of a time is interrupted ( figure 1 ).
  • the chronograph mechanism further comprises reset members for positioning the display members with a measured time in their respective rest positions, upon request, when the measurement is interrupted.
  • the resetting members comprise reset hammers 13, 23, 33 of the chronograph, minute and hour counters, the seconds and minutes hammers being integral with the same lever 42, rotatably mounted on the platinum along a first axis of rotation X1.
  • the hammer hours 33 is carried by a separate lever 43, rotatably mounted on the plate along a second axis of rotation X2.
  • each of the hammers 13, 23, 33 is rotatable with reference to the plate between a low position, in which it cooperates with the periphery of the corresponding core cam 12, 22, 32, by applying a pressure on it, to reset the chronograph counters ( figure 3 ) and a high position in which it is located at a distance from the core cam, which is the case when a measurement of a time interval is in progress or when the chronograph function is simply stopped ( figures 2 and 1 , respectively).
  • the resetting members also comprise a reset command 45 having a first end 46 positioned at four o'clock and intended to cooperate with a control member external (not shown) reset to lower the hammers 13 and 23 against the corresponding core cams.
  • This control 45 has a second end 47 comprising a notch 48 cooperating with a pin 50 integral with the lever 42.
  • this notch 48 is to maintain or hold the hammers in the high position when a time measurement is in progress or simply stopped by the user.
  • the lever 42 further comprises a first spout 56 arranged to cooperate with the lever 40 and lift the blocker 41 of the chronograph wheel 11 at the moment when the hammer 13 comes into contact with the periphery of the core cam 12.
  • the lever 42 comprises a double spout 58, a first free end 59 defines a control surface cooperating with a retaining member in the high position of the hammer 33 of the hour counter.
  • This retaining member is an insulator 60 having substantially the shape of a V and rotatably mounted on the plate along a third axis of rotation X3.
  • the insulator While it cooperates with the free end 59 of the double spout 58 by a first of its two branches, the insulator also cooperates with a spout 61 of the lever 43, defining a bearing surface, by its second branch so as to hold the hammer 33 of the hours counter in the high position when the hammers 13, 23 of the chronograph and minute counters are in the up position.
  • the insulator 60 opposes the force of a return spring 62 acting on the lever 43 to tend to rotate the hammer 33 towards its lower position.
  • the hammers 13 and 23 go down, they release the isolator which releases in turn the lever 43, driven to the lower position of the hammer 33 under the action of the action exerted by the return spring 62.
  • the insulator has a small concavity 63 formed in its first branch to improve the stability of the retaining position and the fluidity of kinematics involved in a reset operation.
  • the double spout 58 of the lever 42 has a second free end 64 arranged to cooperate with the columns of the column wheel 3.
  • the lever 43 has a second spout 65 also intended to cooperate with the columns of the wheel with columns 3.
  • a new pressure on the pusher acting on the control 5 has the effect of rotating the column wheel 3, a first column then raises the lever 42, through the free end 64, and the lever 43, by the intermediate nozzle 65, until the pin 50 returns to be positioned within the notch 48.
  • the hammers 13, 23, 33 are then again locked in the upper position by the retaining means.
  • the first free end 59 of the double spout 58 is repositioned in the concavity 63 of the insulator 60 which follows the movement of the lever 42.
  • the isolator 60 advantageously allows to provide two separate levers to act on the various chronograph counters, which not only provides greater flexibility in the construction of the chronograph mechanism, in particular for the choice of the implementation of counters, but also simplifies assembly. Indeed, each lever with its reset hammer or hammers can be adjusted independently of the other with reference to the position of the associated core cams.
