Definitions

  • the present invention relates to an instantaneous trigger device for use in a timepiece or in any mechanical device.
  • Such a triggering device makes it possible to transform a continuous, smooth or jerky movement, for example the continuous rotation of a wheel of an input mobile into a periodic instantaneous release movement of an output mobile.
  • the triggering device described in CH 578.752 has no pre-arming of the spring, which imposes a significant variation in the braking torque during the arming; moreover, the spring, not being a spiral spring, has only a weak active length; it is therefore not suitable for low drive torques.
  • the cam proposed in this document is not easy to size, it must avoid untimely clearances and ensure clearance of the anchor with minimal friction.
  • the triggering device described in EP 0.327.513 does not include any pre-arming of the spring, which imposes a significant variation in the braking torque during the arming.
  • the movement of the cam is secured only by a jumper, which makes the device sensitive to shocks.
  • the device described is relatively complicated and cumbersome; it comprises in particular folded portions on the hours disk. Such trigger device only seems suitable for the indication of a jumping time.
  • the object of the invention is therefore to propose a triggering device that does not have the known disadvantages of the devices of the prior art and is defined by a triggering device as described in claim 1, particular embodiments or variants being described in the dependent claims.
  • the invention also relates to a mechanical device or a timepiece provided with such a triggering device.
  • the figure 1 shows a block diagram of a triggering device; there is an input mobile 1 directly actuating a cam 2 and a spring device 3.
  • the cam 2 acts on a stop anchor 5 via a stopping fork 4, directly connected at said stop anchor 5.
  • This stop anchor 5 acts on the output mobile 6 via the spring device 3.
  • the trigger device shown at figure 2 comprises an input mobile 1, constituted here of a toothed wheel 10, set in regular rotation movement by a motor member, for example a mainspring via a gear train (not shown here) of a watch movement or any mechanical device.
  • This gear 10 is directly connected via its axis 100, on the one hand with a cam 2 and the other hand to a 1 st end 31 of a spring means 3, consisting of the trigger spring 30.
  • the rotation of the cam 2 causes an alternating angular displacement of a stopping fork 4, movable about its pivot axis 40.
  • the trigger spring 30, shown in detail in FIG. figure 5 Comprises a spiral spring 33, the 1 st end 31 follows the movement of the cam 2, as indicated above, while the 2 nd end 34 of the spiral spring 33 includes one or more regularly spaced teeth 35 on the periphery of the shutter spring 30, said teeth being successively blocked either by the entry pallet 50 or by the output pallet 51 of the stop anchor 5.
  • the cam 2 arms the spiral spring 33 via the movement of the 1st end 31 during the locking of a tooth 35, the release of this tooth 35 by the alternating angular movement of the anchor 5 triggering the device, or the angular displacement of the 2 nd end of the spring means, causing a corresponding angular displacement of an output mobile 6, constituted here of another toothed wheel 60 until the next blockage of the device by the next tooth 35.
  • T is the duration between two successive trips of the device
  • t + T is at all times an identical relative position between the input and output wheels 60. These two wheels 10 and 60 thus have identical average angular speeds. .
  • the cam 2 is integral with the input mobile 1 by its common axis 100.
  • the cam 2 is mounted on this axis 100 so that its angular position relative to the mobile input 1 can be adjusted to ability to finely adjust the angular position of the trigger.
  • the cam 2 has a shape such that it defines, for each angular position, a corresponding relative angular position of the stopping fork 4, thus avoiding inadvertent tripping of the device, in case of mechanical shock for example.
  • the cam 2 can have one or the other of the following forms: eccentric allowing to obtain 2 triggers per cam revolution, cam with 3 vertices, as represented in the figures, in the form of a triangle of Reuleaux, making it possible to obtain 6 triggers per cam revolution, respectively a triggering every 60 ° rotation of the input mobile 1.
  • the cam 2 comprises an odd number n of vertices, connected by convex sides, the center of the circle segment consisting of said side being located on the opposite vertex to that side.
  • Such a cam in cooperation with an anchor 5 as described, makes it possible to obtain n * 2 triggers per cam revolution.
  • the pallets 50 and 51 of the anchor 5 can be provided with ruby lifts.
  • the stop anchor 5 can act directly on the output mobile 6 instead of acting on the trigger spring 30.
  • the trigger spring 30, particularly visible at the figure 5 is formed from a thin plate cut to the desired shape; the entire trigger spring 30 can easily be obtained by a LIGA process or any lithographic photo process or by electroerosion or by any suitable manufacturing process.
  • the shutter spring 30 comprises a 1 st spring end 31 having a fastening means 310, here a two fixing sections, to secure said spring end with the wheel 10 of the input 1.
  • the mobile 2 nd end 34 of the trigger spring 30 comprises teeth 35 mentioned above, each having a form allowing it to be blocked or released by the paddles 50, 51 of the stopper 5.
  • the spring anchor 33 connecting the 1 st spring end 31 at the 2nd end 34 of spring is preferably a spiral spring providing a torque derived when triggered.
  • the 2 nd end 34 of the trigger spring 30 further comprises means fixation, here holes 36 for connecting the trigger spring 30 to the toothed wheel 60 of the output mobile 6 via at least one pin 37, see figure 3 .
  • This fixing by pin of the 2nd end 34 of the trigger spring 30 on the toothed wheel 60 of the output mobile 6 makes it possible to impose, during the mounting of the device, an angle of phase shift between these two elements, respectively a pre-winding spring 33 according to a desired value by choosing the hole 36 in which to place the pin 37.
  • This pre-armature can reduce the torque variation at the input or maintain a movable element in a specific position at the output.
  • At least one slot 11 is provided in the wheel 10 of the input mobile 1, allowing the passage of the pin 37.
  • the direction in which it is installed in the device may depend on the direction of rotation of the input mobile 1.
  • the output mobile 6 has been shown here in the form of a toothed wheel 60; its shape will obviously depend on the function to be performed by the triggering device. It may therefore be instead of the wheel 60, for example a finger for the activation of another mechanism or a cam for the activation of another mechanism or a second trigger device.
  • a triggering device as proposed here has numerous advantages: it instantaneously releases a useful torque whose value can be chosen according to the design of the spiral spring 33 as well as according to the selected prewiring, it is possible to choose different triggering angles according to the The shape of the cam, it is insensitive to shocks, it is of simple design, easy to implement and reliable in use, by design it can be integrated with many mechanisms for various applications.
