Definitions

• the present invention relates to a pistol percussion device.
• gun 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-firing pin. armed set in motion 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 small space, in particular relative to the longitudinal axis of the pistol.
• the percussion spring In order to allow balanced movement of the firing pin, the percussion spring is generally arranged concentrically with the axis of the firing pin, either around it or within it. The striker then serves as a spring guide to reduce the risk of buckling during compression.
• This concentric arrangement greatly limits the choice of the spring and forces a compromise between a short spring subjected to strong cyclical stresses potentially causing fatigue breakages, or a longer spring inducing an elongation of the slideway.
• 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 striker and resting on at least two lateral support surfaces arranged perpendicular to the axis of the striker.
• lateral we mean that the axes of the springs are parallel and arranged both above or below, and to the left or to the right.
• the at least two springs and the corresponding bearing surfaces are arranged symmetrically around the axis of the firing pin.
• 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 of the axis or rotational symmetry of order 3 (3 springs located on a circle at angles separated by 120 °).
• the slide comprises one, or an appropriate combination of at least two of the following characteristics: the striker comprises at least two recesses arranged around its axis to accommodate said at least two springs; - said device only comprises two firing pin springs arranged symmetrically on either side of the firing pin axis, the two springs being arranged on either side of the firing pin axis; said striker springs and said striker are arranged in a slide housing, said housing comprising a stopper surface for the striker springs making it possible to stop the pressure of the springs on the support surfaces of the striker before the emergence of the head striker out of a bottom of the bowl of the slide, so as to allow free travel of the striker at the end of the percussion movement and a return to a rear rest position of the striker at rest without emerging from the bottom of the bowl; - A return spring bearing on the slide and applying a rearward force to the striker is disposed in said housing of the slide; the mass of the striker is between 1, 5 and
• said housing is provided in a housing fixed to the slide; - said housing is made of polymer; said striker and said at least two springs are pre-assembled in said housing, said springs being held in position by a spring support comprising at least two spring guides inserting inside said springs;
• the slide is essentially metallic and the striker comprises a support rod for the striker head sliding in a guide duct (preferably cylindrical) of the striker formed in the metal of the slide;
• said at least two springs, the respective axes of which are mutually parallel, are springs of the compression type; the respective axes of said at least two springs and the axis of the striker are coplanar.
• Figure 1 shows a section of an example of a pistol according to the invention.
• Figure 2 shows a top view and side view of a slide of a gun according to the invention.
• Figure 3 shows a perspective view of a pistol firing pin according to the invention.
• Figure 4 shows a perspective view of a firing pin locking safety butterfly.
• Firing pin safety pin housing recess Recess equivalent to the return spring housing in order to balance the throttle.
• Bowl base (or breech base or percussion base)
• 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 firing pin 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 recesses
• the thrust of the spring is exerted only on part of the stroke of the firing pin.
• the end of its forward travel 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 firing pin 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.
• the use of 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 represents the most expensive component of the gun. A significant reduction in its price can be obtained by the use of a plastic housing 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 inserting into the interior of said springs 4,6.
• a spring support 21 comprising at least two spring guides inserting into the interior of said springs 4,6.
• guiding the striker to remain concentric with the primer can represent an additional technical difficulty.
• 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 guidance is then done via a shaft or rod for supporting the striker head 9 in a 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 conduit for guiding the striker 1 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 lugs 10,11 of safety and a firing pin safety butterfly 2 arranged on a rotation axis 27 fixed to the slide and parallel to the translation axis of the firing pin 20, said safety butterfly 2 being able to rotate in a vertical plane between a firing position and a blocking position, 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 firing position, 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.
