  • the roller 53 of the pin 51 is no longer in contact with the hammer rocker 65 and the peg of the pin 72 of the latter seat in the notch of the lateral portion 88 of the jumper 67.
  • the movement of the rocker 65 has driven directly the pin 64 of the hammer 61 according to the translation K in the light 100 and, indirectly, the second pin 66 of the hammer 61 according to the translation L in the light 102 so that the hammer 61 has moved away from the cores 55, 57 and 59. Therefore, the reset device 25 illustrated in FIG. figure 4 is in its stable position deactivated.
  • the chronograph mechanism 7 is activated, that is to say that the indicator device 17 begins to visualize the elapsed time.
  • the control 41 is no longer driven by the shockproof device 35.
  • the chronograph mechanism 7 is therefore activated, that is to say that the indicator device 17 continues to measure the elapsed time, the reset device 25 is in its stable inactive position, the standardization device of efforts 37 is in its equilibrium position and the kinematics connected to the pushers 19 and 21 in their rest position.
  • the clutch device 29 is activated and the immobilizer 31 deactivated.
  • the shockproof device 35 goes into the disengaged position and does not cause the control 41. If the support on the pusher 19 is less than the predetermined force, the kinematics, explained above, causes the control hook 43 according to the tangential movement F adapted to print a trigonometric rotation G, at substantially an angle of 30 degrees, to the column wheel 45.
  • control system 23 returns to a state substantially symmetrical to that of the figure 3 which implies that it again allows the activation of the resetting device 25 (the finger 83 of the reset lever 63 is again facing a space between two columns of the castellated wheel 48).
  • This state also deactivates the clutch device 29 (that is, disengages the chronograph mechanism 7 from the watch movement 3) and activates the immobilizer 31 (that is, makes the device static).
  • gear device 27 for example by means of said third wheel of the column wheel 45 as explained above.
  • the user can then comfortably read, by the indicating device 17 (made immobile) of the display system 9, the elapsed time that he wished to measure.
  • the pusher 21 moves substantially in a translation N until that the rear of the pusher 21 comes into contact with the striking zone 93 of the shockproof device 33.
  • the movement of the pusher 21 is transmitted to the main part 91 of the shockproof device 33 which then prints a retrograde rotation P around from the A4 axis.
  • the shockproof device 33 goes into the disengaged position. This means that the connection between the peg 96 of the reset lever 63 and the notch of the jumper 95 formed on the main part 91 dissociates. Therefore, the translation N of the pusher 21, substantially oriented towards the core 59, only induces the rotation P of the main part 91 of the shockproof device 33 in the retrograde direction. The rotation P of the main part 91 is limited when the finger 92 meets the end of the hole 87 as illustrated in FIG. figure 8 .
  • a flange 131 of the pusher 21 (visible at the figure 8 ) against the housing 11 of the timepiece 1 which more surely limits the stroke of the pusher 21.
  • it can also be provided a limit stop of the At any time, when the pusher 21 is released, the expansion force of the jumper 95 brings it back to the ankle 96.
  • the shockproof device 33 thus makes it possible to protect the kinematics attached to the reset lever 63 and to automatically repositioning mechanically.
  • the shockproof device 33 remains in the normal position and, in a third step, transmits to the delivery lever at zero 63 his movement.
  • the resetting lever 63 is driven in the same retrograde rotation P around the axis A4 and, incidentally, its finger 83 and its arm 81.
  • the arm 81 In a fourth step, the arm 81, by its movement O substantially oriented towards the cores 55, 57 and 59, comes into contact with the second roller of the post 66 and begins to train.
  • the movement O of the arm 81 of the reset lever 63 is successively translated by the movements L '(substantially opposite to L explained above) of the tenon 66, K' of the tenon 64 (substantially inverse to K explained above) and H 'of the hammer rocker 65 (substantially reverse to H explained above).
  • the hammer rocker 65 is in a stable position by contacting the roller of its peg 72 against the lateral face 88 of the jumper 67, it exerts a counter-force to the movement O.
  • the force feedback on the pusher 21 felt by the user is generated mainly by the relative displacement of the tip 125 of the intermediate lever 121, which is driven according to the movement R around the axis A1 by the reset lever 63 by means of the finger assembly 126 - groove 124, relative to the jumper 123.
  • the thrust force on the pusher 21 must therefore counteract the conjugate antagonistic efforts exerted mainly by the spacing J of the jumper 123 with respect to the tip 125 and the spacing M of the vertical portion 82 of the jumper 67 with respect to the ankle 72.
  • the fifth step is initiated. It corresponds to the moment when the roller of the peg 72 of the rocker 65 exceeds the common edge between the upper face 86 and the lateral face 88 of the vertical part 82 of the jumper 67. Indeed, at this moment, the movement N of the pusher 21 no longer requires the jumper 67 to move away according to the movement M but on the contrary allows that the jumper 67 tends to return to the equilibrium position.
  • the hammer rocker 65 is no longer displaced by the force exerted on the pusher 21 but substantially by the force exerted by the rotation. trigonometric relaxation of the vertical portion 82 of the jumper 67 about the axis A5. The end of the movement path (H ', K', L ') of the reset device 25 is then "automatically" performed.
  • the arm 81 of the reset lever 63 is no longer in contact with the second roller of the post 66 of the hammer 61 and the peg of the peg 72 of the hammer rocker 65 seat against the upper part 86 of the jumper 67.
  • the movement of the rocker 65 has driven directly the pin 64 of the hammer 61 according to the translation K 'in the light 100 and, indirectly, the second pin 66 of the hammer 61 according to the translation L' in the light 102 so that the hammer 61 has contacted the cores 55, 57 and 59.
  • the resetting device 25 is therefore activated again.
  • the double-arm configuration 60, 62 of the hammer 61 as explained above makes it possible to improve the balancing of the striking forces of the cores 55, 57, 59 by the stops 54, 56, 58 of the hammer 61. Moreover, advantageously the striking forces are no longer dependent on the force exerted on the pusher 21 but on the relaxation force of the jumper 67.
  • the chronograph mechanism 7 is deactivated and its indicator device 17 reset. Nevertheless, at any time, if the force exerted on the pusher 21 induces a force on the jumper 95 - pin 96 which substantially exceeds 25 N, the reset lever 63 is no longer driven by the shockproof device 33.
  • the shockproof devices 33 and 35 thus protect the chronograph mechanism 7 against the violent actuations of the pushers 19 and 21.
  • the devices 33 and 35 protect the chronograph mechanism 7 also in the case where the two pushers 119 and 21 are actuated at the same time . Indeed, one 19 will tend to make inactive the reset system 25 and the other 21, tend to make active the same system. Thanks to the devices 33 and 35, as soon as at least one of the links 116-115 and 95 - 96 reaches its predetermined stress threshold, preferentially equal to 25 N, it disengages and leaves the other control of the reset device 25. Similarly, the castellated wheel 48 of the column wheel 45 is not likely to be damaged by a violent support the finger 83 of the reset lever 63.
  • a simple release of the pusher 21 will mechanically release the stress between the tip 125 of the intermediate lever 121 and the jumper 123.
  • the effort equalization device 37 then tends to return to its equilibrium position and causes its displacement.
  • the chronograph mechanism 7 is therefore found again in its configuration of the figure 3 .
  • the chronograph mechanism 7 is therefore inactive, the resetting device 25 is in its stable active position, the force equalization device 37 is in its equilibrium position and the kinematics connected to the pushers 19 and 21 in their position. rest position.
  • the uncoupling force of the jumper assemblies 115/95 - peg 116/96 of the shockproof device 35/33 is greater than that of the assembly 125 - jumper 123 which is, itself, greater than that of the sets of ankles 72- 86/88 faces jumper 67.
  • the present invention is not limited to the illustrated example but is susceptible of various variations and modifications that will occur to those skilled in the art.
  • the mounting of the light assemblies 47- pin 49 and / or finger 68/122/126 - groove 69/120/124 can be reversed without the operation of the timepiece 1 is affected. This is of course valid for other sets of sets of the timepiece.
  • the movements B, N actuating the pushers 19, 21 can not be limited to a translation, any movement and / or control member other than a pusher can be envisaged.
  • one of the two pushers 19, 21 control that is to say, directly push their associated functions, that is to say without anti-shock device 35 , 33 intermediate.
  • This embodiment is not part of the claimed invention.
  • rollers can not be limited to the example of the figures as explained above but any timepiece may comprise less or more and / or different configuration (diameter of the axis on which it is mounted, thickness of the roller, etc.).
  • each state of the column wheel 45 it may be provided a jumper which cooperates with one of its teeth.
