Definitions

  • the invention relates to a micromechanical mechanism provided with a percussion actuation system, in particular for watchmaking.
  • the invention also relates to a timepiece movement comprising such a micromechanical mechanism.
  • a striking mechanism can be combined with a traditional watch movement to serve in particular as minute repeaters or to signal a programmed alarm time.
  • a striking mechanism generally comprises at least one gong made of sapphire, quartz or metallic material, such as steel, bronze, precious metal or metallic glass. This gong can describe for example at least a portion of a circle around the watch movement in the watch cage.
  • the stamp is fixed by at least one of its ends to a stamp holder, which is itself secured to a watch plate.
  • a hammer of the mechanism is rotatably mounted on the plate, for example near the gong holder, so as to strike the gong to make it vibrate.
  • the sound produced by the gong struck by the hammer lies notably in the audible frequency range of 1 kHz to 20 kHz. This allows the wearer of the watch to be notified of a well-defined time, a programmed alarm or a minute repeater.
  • the striking mechanism of a watch can comprise two or more gongs fixed by one of their ends to the same gong holder, which is itself integral with a plate.
  • Each stamp can be struck by a respective hammer.
  • each hammer is driven by its own drive spring, which had to be wound beforehand, so as to drive the hammer against the gong, in order to signal a minute repeater or an alarm hour.
  • Two damping counter-springs are each provided to push back and maintain the two hammers at a distance from the gongs in a rest mode. In a striking mode, the damping counter-springs act with great force and slow the fall of each hammer before striking against the respective gong. These counter-springs make it possible, following the strike, to push back each hammer towards their rest position.
  • Eccentrics are also provided for adjusting the operation of the counter-springs to essentially prevent any bouncing of each hammer against the respective gong.
  • a drawback of known actuation systems is the amount of energy they require to operate optimally. This energy is either provided by the barrel or by manual actuation.
  • the hammer in the case of a chime, the hammer must be actuated automatically in order to operate, in particular thanks to the energy supplied by the barrel.
  • the pressure required can be relatively high, which is not pleasant for the person using the mechanism.
  • an actuation system which operates continuously.
  • the movement must be maintained at a predefined frequency.
  • Detent escapement mechanisms are known, which do not include an anchor. However, these mechanisms are complex to implement and to actuate.
  • the object of the invention is therefore to overcome the drawbacks of the aforementioned state of the art by providing an innovative actuation system, in particular for a timepiece, with the aim of avoiding a significant use of energy necessary to its operation.

  • the force of attraction of the magnet is used to put the striker in the position of percussion.
  • the striker transmits a quantity of movement necessary to the mobile element. Thanks to the momentum of the striker, the moving element receives enough energy to trigger the micromechanical device. Thus, the energy necessary for actuating the striker and/or the movable element is saved.
  • the transmitted energy substantially corresponds to the momentum of the striker and is therefore relatively constant, independently of the energy of the striker actuation system, the system thus forming a constant-force system.
  • the actuation energy of the micromechanical device is lower.
  • the cylinder is less stressed, or manual actuation is easier.
  • the speed of the mobile element can be adapted. For example, one can choose a mobile element of reduced mass, which moves with a greater speed than that of the striker having a greater mass. A lighter mobile element moving quickly reduces the risk of rebound after the impact against the gong.
  • the movable element comprises a magnetic conductive material.
  • the striker comprises a magnetic conductive material, so as to be attracted by the magnet.
  • the movable element is in contact with the magnet in its rest position.
