Definitions

  • the present invention relates to the field of mechanical watchmaking. It relates, more particularly, to an escapement mechanism arranged to transmit mechanical energy pulses from a driving source to an oscillating timepiece regulator by means of a leaf spring working in buckling around a inflection point.
  • the leaf spring is capable of accumulating energy from the power source between two pulses and transmit it to said oscillating regulator at each pulse via a first and a second latch.
  • the mechanism comprises a plate 14 provided with a plate pin 16 mounted on the rocker 10.
  • the mechanism also comprises a first trigger rocker 18, ending in a fork 20 of conventional type, provided with an inlet horn 20a and an output horn 20b and a dart 20c, intended to cooperate with the pin 16 and with the plate 14, respectively.
  • the flip-flop terminates in a shank 22 and still carries a first and second projecting active element 24 and 24 located in the plane of the leaf spring 12.
  • the mechanism also comprises a second arm flip-flop 26, comprising a central portion and two symmetrical wings, each carrying at their end a key-pin assembly 28 and 29, intended to cooperate with the leaf spring 12.
  • the central portion also receives a third 30 and a fourth 31 active elements, intended to cooperate respectively with a first 32 and a second 34 wheels exhaust.
  • Both latches 18 and 26 are rotatably mounted one with reference to the other.
  • stop and guide means which will not be described in detail, bind them, but with play, so that a displacement of a rocker causes the displacement of the other, but with a certain lag.
  • the rocker 10 In the next step, the rocker 10 continuing its oscillation, the pin 16 strikes the input horn 20a of the fork 20.
  • the first rocker 18 then acts on the leaf spring 12 via the first active element 24
  • the leaf spring 12 then suddenly switches from its unstable position to a stable state corresponding to a reverse mode buckling of the previous mode.
  • This change of state allows the leaf spring 12 to act on the key-pins 28 and 29, which pivots the second flip-flop 26, causing the unlocking of the second escape wheel 34.
  • the second flip-flop 26 pivots until the third active element 30 encounters one of the teeth of the first escape wheel 32.
  • the latter also acts on the second active element 25 of the first flip-flop 18, thus communicating to the balance 10 the energy accumulated during the arming of the leaf spring 12, via the output horn 20b.
  • Such an escape mechanism is particularly interesting, especially for the advantages mentioned in the aforementioned document. More particularly, it makes it possible to obtain an interesting yield by decreasing the stopping times of the different elements and the inertia to overcome during operation.
  • the present invention is intended to solve this problem. It also proposes a particularly advantageous embodiment in its implementation.
  • the invention also relates to a part used in the assembly of the mechanism and a method for this assembly.
  • the leaf spring 12 is made of monocrystalline silicon. interesting elastic characteristics have, by way of simple illustration, been obtained with a leaf spring 12 of 0.02 mm in the direction of the first axis and about 0.1 mm thick. Silicon allows particularly precise machining for extremely small dimensions.
  • the latter comprises two open cells 55 arranged symmetrically with respect to its point. of inflection, inside which are placed fingers 56 and 57, arranged projecting relative to the rocker and replacing the key-pins 28 and 29.
  • the transmission of energy, on the one hand, and accuracy positions of the rocker 26 and the leaf spring 12, on the other hand, are thus perfectly mastered.
  • Adjusting the position of the ends of the leaf spring 12 could also be obtained by moving away from one another the areas of the frame 50 crossing the axis AA.
  • the figures 4 and 5 show different stages of the assembly of the mechanism according to the invention.
  • an exhaust plate is already in place, and the last wheel 40 of the finishing train.
  • the levers 64 are also positioned.
  • the second flip-flop 26 and the first portion 18a of the first flip-flop 18 are assembled and the one-piece piece 70 is arranged, by housing the pins 54 in the corresponding oblongs 52, and by assembling the first 18a and the second 18b parts of the first flip-flop 18.
  • the support arms 60 are mounted before installing the exhaust bridge ( figure 5 ), which comprises complementary pivoting means including the first 18 and second 26 flip-flops.
