Definitions

  • the present invention relates to a pistol percussion device.
  • pistol firing devices comprise either a hammer producing a shock at the rear of a firing pin whose front end strikes the primer of a chambered ammunition, or a pre-cocked firing pin placed in position. movement by a compressed spring when loading the weapon.
  • the spring In the case of pre-cocked firing pins, the spring must be able to store enough energy to be able to ensure a sure percussion, while occupying a reduced space, in particular in relation to the longitudinal axis of the pistol.
  • the percussion spring In order to allow a balanced movement of the striker, the percussion spring is generally arranged concentrically with the axis of the striker, either around the latter or inside the latter. The striker then serves as a spring guide to reduce the risk of buckling during compression.
  • This concentric arrangement greatly limits the choice of spring and forces a compromise between a short spring subjected to strong cyclic stresses potentially causing fatigue breakage, or a longer spring inducing an elongation of the slideway.
  • the reliability of the firing device is directly linked to the quantity of energy stored in the firing pin spring, and given the constraints mentioned above, it is difficult to increase this in the devices of the prior art. if not to the detriment of the size of the device.
  • the invention relates to a pistol comprising a firing device arranged in a slide, said device comprising a firing pin comprising a firing pin head and at least two firing pin springs arranged laterally on the side of the axis of the firing pin and taking bearing on at least two lateral bearing surfaces arranged perpendicular to the axis of the striker.
  • the at least two springs and the corresponding bearing surfaces are arranged symmetrically around the axis of the striker.
  • symmetrical we mean in the present description any type of symmetry, including rotational symmetries, so that the torques applied by the at least two springs cancel each other out: it can be two springs arranged symmetrically on either side and side. other of the axis or rotational symmetry of order 3 (3 springs located on a circle at angles separated by 120 °).
  • the present invention relates to a pistol comprising a firing device in which the percussion energy is provided by at least two firing pin springs 4,6 arranged symmetrically on either side of the axis of the firing pin 20, unlike the prior art where a single spring arranged concentrically to the axis is used.
  • the use of two springs makes it possible to reduce the length of each of them for a given energy and level of stress. This makes it possible to store sufficient energy in the springs while ensuring a long service life given the level of acceptable stresses in the springs, in particular with regard to the fatigue of the springs. However, the greater the energy, the more percussion is ensured, in particular under adverse conditions.
  • the use of several springs adapted in length and working in parallel allows the use of a lower stiffness to guarantee the same level of energy. This with the aim of also reducing the energy necessary to provide for the “racking” of the weapon (manual rearming).
  • the stiffness of the percussion springs being weaker, it is therefore possible to reduce the force of the recuperator spring dimensioned so as to put the slide in battery and band the percussion springs.
  • the invention thus also makes it possible to improve the general ergonomics of the weapon and its lifespan.
  • the placement of the springs next to the striker makes it possible to make it tapered and lighter.
  • the lighter the striker the more reliable the firing of the primer is for the same potential energy stored in the percussion spring (s).
  • the mass of the striker is between 1.5 and 6g, preferably between 2 and 3g.
  • the striker comprises at least two symmetrical recesses 13 on either side of its axis 20 to accommodate the at least two springs 4.6. These recesses make it possible to reduce the total weight of the firing pin and to reduce the torque generated by each spring by bringing it closer to the axis of the firing pin.
  • the thrust of the spring is exerted only over part of the stroke of the striker.
  • the end of its forward stroke then takes place without contact with the spring.
  • a weak return spring makes it possible to push the striker out of the bottom of the bowl.
  • the vertical displacement of the cartridge during unlocking can then be done without rubbing on the firing pin and therefore without risking breaking it.
  • the free travel of the firing pin is generally achieved by adding components which go into the sense of increased complexity and an increase in the price of the weapon.
  • the percussion springs 4, 6 no longer bear on the striker but against a stop surface 22 of a housing in the slide 5 accommodating the firing device of the invention.
  • the striker therefore travels freely from this point.
  • a light striker then allows the use of a very weak striker return spring and therefore having little impact on the percussion energy stored in the system, the return spring being placed in opposition to the springs. percussion.
  • the slide is the most expensive component of the gun. A significant reduction in its price can be obtained by using a plastic case which eliminates costly machining operations in the slide.
  • said housing is provided in a housing 24 fixed to the slide 5.
  • said housing 24 is made of polymer while the rest of the slide is essentially metallic.
  • said striker 1 and said at least two springs 4,6 are pre-assembled in said housing 24, said springs being held in position by a spring support 21 comprising at least two spring guides fitting inside said springs. 4.6.
  • the striker 1 is preferably guided over its entire stroke in a channel 29 formed in the metal part of the slide 5 opening into the bottom of the bowl 23. The guiding is then done via a shaft or support rod. the striker head 9 in the bore opening into the bottom of the bowl 23.
  • the slide is essentially metallic and the striker 1 comprises a support rod for the striker head 9 sliding in a cylindrical guide duct for the striker 1 formed in the metal of the slide 5.
  • the gun further comprises a firing pin safety device integrated into the slide 5, the firing pin 1 comprising a lateral extension 25 comprising two safety lugs 10,11 and a firing pin safety butterfly 2 disposed on a rotation axis 27 fixed to the slide and parallel to the translation axis of the striker 20, said safety butterfly 2 being able to rotate in a vertical plane between a firing position and a position locking, said butterfly 25 comprising two bearing surfaces 17,18 on which resting said lugs 10,11 when said butterfly is in the locking position and two recesses 14 capable of allowing said lugs 10,11 to pass when said butterfly is in the locking position. firing, the center of mass of said butterfly 2 being on its axis of rotation 27 and the axis of rotation 27 being a main axis of inertia of said butterfly 2.
  • the butterfly 2 is actuated in rotation by a safety control trigger 30, itself actuated by the firing control chain controlled by a trigger tail.
