Definitions

  • the subject of the present invention is a device for triggering a pulse and more particularly a periodic device for triggering a mechanical pulse for controlling a mechanism, for example a date mechanism of a movement or module. watchmaking.
  • Such devices for periodically triggering a pulse are known from the document EP 1 498 788 and FR 745.474 and more particularly by the document FR 747 876 considered to be the closest state of the art which discloses a mechanical pulse triggering device for a watch movement comprising a control wheel driven in rotation by a mobile of a clockwork movement; a control cam having at least one lift concentric with the control wheel and connected thereto by a driving device in one direction only; a pivoting lever having a feeler cooperating with the peripheral surface of the control cam against which it is applied by an elastic action; a barrel whose drum comprises a stop capable of being pressed against a blocker which prevents rotation of the drum of the barrel, in that the drop of the probe of the lever of a lifting of the control cam actuates the blocker to release the barrel drum so that the barrel can disarm from a predetermined angle.
  • the present invention provides a solution to this problem by making the force or the torque necessary for the actuation of the pusher independent of the motor of the clockwork controlling the moment of the pulse.
  • the device according to the invention makes it possible to trigger a mechanical pulse at a given moment, without the force necessary to actuate the pusher delivering the mechanical pulse does not depend on the motor of the watch movement controlling the moment when the pulse is issued and is distinguished by the features listed in claim 1.
  • the triggering device of a pulse will be described with reference to the embodiment illustrated in the drawing by way of example which is a device for controlling from a watch movement, once by day, a pulse on a control pusher.
  • the device is illustrated mounted on a plate 1 and comprises a control wheel 2 pivoted concentrically to an axis 3 and driven at a rate of a complete revolution per day from a wheel hours 4 of a clockwork movement no illustrated.
  • This control wheel 2 comprises oblong slots 5a, 5b, 5c, three in the illustrated example, distributed preferably uniformly about the axis of rotation of this control wheel 2.
  • a spring 6 with three branches is arranged under the control wheel 2 whose hub 7 is pivoted on the axis 3 and serves in turn the pivot to the control wheel 2.
  • This hub 7 passes through the control wheel in the center and ends with an end having a plate 8.
  • a control cam 9 in the form of a snail cam is driven on the end of the hub 7 of the spring 6.
  • the spring 6 comprises three branches 10, 11, 12 each cooperating with one of the lights 5a, 5b, 5c of the control wheel 2.
  • the end of each leg 10, 11, 12 comprises a folding ensuring that these ends are are in the rest state branches of the spring 6, engaged in the corresponding lights 5a, 5b, 5c of the control wheel 2.
  • the spring 6 is also driven as is the control cam 9.
  • the branches 10, 11, 12 of the spring 6 deviate axially from the control wheel 2, so that neither the spring 6 nor the control cam 9 are driven in a counter-clockwise direction.
  • This arrangement thus constitutes a unidirectional coupling device for driving the control cam 9 in a single direction of rotation by the control wheel 2.
  • the lights 5a, 5b and 5c are on different radii so that each of them can cooperate only with a corresponding end 10, 11, 12 of the spring 6.
  • the lights 5a, 5b, 5c can be coupled to the spring 6 only in a single position per turn where the folded ends 10, 11, 12 enter said lights.
  • the control wheel 2 has the double tooth of the hour wheel 4 and is therefore rotated at the rate of a complete revolution in twenty-four hours.
  • the trigger device further comprises a lever 13 pivoted on the plate 1 at 14.
  • This lever comprises a feeler 15 cooperating with the periphery of the snail cam 9 since the lever 13 is subjected to the action of a return spring 16 tending to apply the probe 15 against the periphery of this control cam 9.
  • a finger 17 is pivotally mounted at 18 on the free end of the lever 13 and ends with an actuating face 19.
  • the other end of the finger 17 comprises a pin 20 subjected to the action of a return spring 21 fixed on the lever 13 and tending to maintain the pin 20 bearing on the edge of the lever 13.
  • the trigger device further comprises a barrel comprising a drum 22 enclosing a mainspring and a ratchet with its ratchet for arming the spring like a conventional barrel.
  • the spring of the barrel is fixed at one of its ends on the axis of the barrel 23 while the other is fixed inside the barrel drum 22.
  • the drum drum 22 is secured to an actuating cam 24 in the form of a snail cam whose periphery cooperates with the feeler 25 of a rocker 26 pivoted on the plate 1 at 27.
  • this rocker 26 cooperates with the pusher 29 of a corrector 30, this pusher moving linearly relative to the sleeve of the corrector 30 against the action of a non-illustrated return spring tending to move said pusher 29 towards the free end 28 of the rocker 26.
  • the rocker 26 is subjected to the action of a return spring 37 pressing the probe 25 against the actuating calm 24.
  • the drum 22 of the barrel comprises a stop 31 resting on the free end 32 of a pawl 33 pivoted at 34 on the plate 1 and subjected to the action of a return spring 35 tending to hold the free end 32 of pawl 33 against the peripheral wall of the drum 22 of the barrel.
  • the other end of the pawl 33 carries a pin 36 located, when the pawl 33 is in the rest position, in the path of the actuating face 19 of the finger 17 of the lever 13, when the lever 13 falls from the most eccentric of the control cam 9.
  • This barrel drum 22 rotates under the action of its own barrel spring in the counterclockwise direction, the snail cam 24 pushes the rocker 26 causing the actuation that is to say the pulse of the pusher 29.
  • Au After one turn the barrel drum 22 is again blocked by the pawl 33 and the probe 25 of the rocker 26 has fallen back on the lower part of the snail cam 24.
  • the tripping cycle can start again.
  • the time taken by the barrel 22, 23 to disarm a lap will depend on the tension of its mainspring and the resistance of the control mechanism actuated by the pusher 29.
  • the control mechanism is a module of watchmaking as a calendar, the disarming and therefore the duration of the pulse are quite fast, for example about one second or less.
  • control wheel 2 the control cam 9 and the lever 13 provided with its finger 17, constituting first means, which determine the moment of the pulse but the energy necessary to push the pusher 29 is delivered by the barrel 22, 23 and not by the motor of the clockwork driving the control wheel 2.
  • the barrel 22, 23, the actuating cam 24, the pawl 33 and the flip-flop 26 constituting second means,
  • the finger 17 and the pawl 33 (and the return springs 21 and 35) constitute a blocker of the barrel 22, 23 which is released for a short time immediately after the fall of the lever 13 so that the barrel can disarm a predetermined angle.
  • this disarming angle is 360 ° or a turn, but in some variations the disarming angle of the barrel may vary. For example, if the cam 24 has two lifts and the barrel drum has two stops, the disarming angle of the barrel could be 180 °.
  • the tripping device delivers one pulse per twenty-four hours, but in variants, the interval between two pulses may be different. It suffices either to drive the control wheel 2 at another speed, or to provide a control cam 9 with two or more lifts.
  • the trigger device described may be supplemented by a safety device (not shown) so as to be able to limit the number of pulses between two windings of the barrel 22, 23. Indeed when the barrel is almost completely disarmed, it can not completely turn and stop before having completed his impulse, which is not desired.
  • an eccentric Malta cross (not shown) which is a quarter turn at each turn of the barrel under the action of a finger fixed on the barrel shaft 23.
  • This Maltese cross has one of its four full teeth which prevents the barrel from disarming more than three turns. After disarming these three turns the Maltese cross will have a position such that it will prevent, through a lever (not shown), the pawl 33 to lift and prohibit the triggering of a new impulse.
  • the pulse triggering device described can control, from a clockwork movement, an additional module located either in the same enclosure or box as the movement or outside this box, the corrector 29, 30 allowing a traverse waterproof of this watch case.
  • this device is particularly well suited to equip a mechanical timepiece, manual winding. In this case, it is possible to remount simultaneously from a winding crown the barrel forming the motor of the watch movement and the barrel 22, 23 of the present triggering device.
  • the mechanical pulse triggering device comprises first means 2,6,9,13 and 17 driven by a clockwork movement, in the example illustrated by the hour wheel 4 of a movement timepiece not illustrated, determining the moment or moments when a pulse must be delivered and second means 22,23,24,26,30,33, triggered by said first means, delivering a mechanical pulse of predetermined force and amplitude from a motor member 22,23 independent of the watch movement.
