Definitions

  • the present invention relates generally to a burglar-resistant piston lock, in particular for a motor vehicle.
  • a lock of the type comprising a stator in which a rotor pivots comprising a housing sliding axially inside which the pistons are housed.
  • This housing comprises, at its end opposite to the entry of the key, a coupling nose intended to cooperate with a recess arranged in a driver of a control arm of a lock.
  • the present invention solves these problems and proposes for this purpose a burglar-resistant piston lock, in particular for a motor vehicle comprising a stator, a rotor, pistons mounted in a housing of the rotor, said housing being able to slide axially under the action of an axial pressure exerted by a conforming key head against a stop of said housing so that a coupling nose of the housing comes into engagement with a recess of a coach, characterized in that means are provided whose action, after a first axial push of the key, keeps the coupling nose engaged with the recess of the coach .
  • said means consist of a pin spring, a first branch of which cooperates with a notch in the coupling nose and a second branch of which cooperates with a notch of the rotor.
  • a lock according to the invention comprising a stator 10 forming the body of the lock inside which pivots a rotor 12 which has a housing 14 which can slide axially.
  • This housing 14 comprises, at its end opposite the entry of the key, a coupling nose 16 cooperating with a recess 18 of a driver 20 of the control arm 22 of a lock, for example of a door or of a motor vehicle trunk.
  • the housing has radial bores 24 opening into the key channel 26 of the rotor 12 and in which are housed pistons 28 returned to the channel 26 by springs 30.
  • the rotor 12 and its housing 14 pivot freely in the body 10, while being angularly locked, key removed (FIG. 1) by a ball 32 returned by a spring 34 against a recess 36 of the stator 10.
  • the pistons 28 have a groove 38, situated at a variable height to constitute a code corresponding to the notching of the key 40, so that, when this key is introduced (FIG. 2) the grooves 38 of the pistons 28 are aligned axially.
  • the key channel 26 is terminated by a stop 42 with which the end of the key 40 cooperates.
  • a conforming key 40 aligns the grooves 38 of the pistons 28 thereby freeing the rotor 12 and its housing 14 in rotation and in translation.
  • the lock comprises means making it possible to keep the nose 16 engaged with the driver 20 and this without having to exert a permanent axial thrust on the key 40.
  • These means consist of a pin spring 44, one of the branches 46 (FIG. 3) of which cooperates with a notch 48 in the coupling nose 16 and of which the other branch 50 cooperates with a notch 52 of the rotor 12.
  • branches 46.50 of the pin extend transversely relative to the axis of the rotor 12.
  • branches 46 and 50 of the spring 44 are parallel and cooperate with notches 48 and 52 preferably having a triangular shape.
  • the notches 48 and 52 are offset axially so that the spring 44 is inclined (on the left in FIG. 1) and thus exerts on the 'rotor assembly 12 - housing 14 a push from the right to the left in the figure thus helping to avoid any engagement of the nose 16 with the driver 20.
  • the spring 44 due to the axial offset of the notches 48 and 52, thus occupies a first stable position due to the prestressing of which its branches 46.50 are the object.
  • the spring 44 thus occupies a second stable position still due to the preload of its branches 46.50. We can therefore consider the spring 44 as a bistable means for holding the housing 14 in position.
