Abstract

The present invention relates to a percussion mechanism for a firearm and allows a reduced stroke of the hammer without a loss of power of its spring. The percussion mechanism consists of a movable support 1, to which the spring 3 are fastened, the movable support contains the percussion spring 4 and its tension stop 5, it also comprises the detent 6 fixed to the piston 7 connected to the link 8 of the hammer 9, the movable support is locked by means of a piece 10 and its spring 11, the movable support comprises a return spring 12, its stroke is limited by a stop 13, a stop 14 on the movable breach actuates a lever 15 for releasing the movable support when the movable breach recoils. Percussion mechanism for any weapon using a hammer.

Description

La présente invention concerne un mécanisme de percussion pour arme à feu et permet une course réduite du chien sans perte de puissance de son ressort, pour une meilleur précision du tir. The present invention relates to a percussion mechanism for a firearm and allows a reduced stroke of the dog without loss of power of its spring, for better accuracy of the shot.

Le système de percussion actuel utilisant un chien le pivotement important de celui-ci pour le passage de la culasse mobile rend sa position d'accrochage très éloigné du percuteur pour ne pas détendre le ressort du chien ce qui ne favorise pas la rapidité du tir et donc sa précision. The current percussion system using a dog the significant pivoting of the latter for the passage of the movable breech makes its hooking position very far from the striker so as not to relax the spring of the dog which does not promote the rapidity of the shot and therefore its precision.

Le mécanisme de percussion selon l'invention permet de remédier à cet inconvénient par l'utilisation d'une gâchette solidaire d'un support mobile qui contient également le ressort du chien, le support mobile est verrouillé momentanément par un arrêtoir pour lui donner un point d'appui permettant la compression du ressort du chien loraque la culasse mobile recul, dès que le tenon de la biellette du chien est passer sous la gâchette une butée situé sur la culasse mobile renvoie un levier qui actionne un arrêtoir et déverrouille le support mobile pour permettre de poursuivre le pivotement'du chien nécessaire au passage de la culasse mobile,lorsque la culasse mobile se referme le support mobile remonte sous l'action de son ressort de rappel et positionne le chien prés du percuteur. The percussion mechanism according to the invention overcomes this drawback by using a trigger secured to a movable support which also contains the dog's spring, the movable support is momentarily locked by a stopper to give it a point of support allowing the compression of the spring of the dog when the moving breech moves back, as soon as the tenon of the rod of the dog is pass under the trigger a stop located on the movable breech returns a lever which actuates a stopper and unlocks the movable support for allow the dog to continue pivoting necessary for the passage of the movable bolt, when the movable bolt closes the movable support rises under the action of its return spring and positions the dog near the striker.

Le mécanisme représenté sur la figure unique comporte le support mobile (1) sur lequel est fixé la gâchette (2) et son ressort (3),le support mobile contient le ressort de percussion (4) et sa butée de tension (5) il comporte également le tenon d'arrêt (6) solidaire du piston (7) relié à la biellette (8) du chien (9),sur le boiter culasse est fixé l'arrêtoir (IO) du support mobile et son ressort de rappel (II) le support mobile comporte un ressort de rappel (I2), la course du support mobile est limité par une butée (13) fixé sur le boiter culasse. The mechanism shown in the single figure comprises the movable support (1) on which the trigger (2) and its spring (3) is fixed, the movable support contains the percussion spring (4) and its tension stop (5) it also includes the stop pin (6) integral with the piston (7) connected to the link (8) of the dog (9), on the cylinder head box is fixed the retainer (IO) of the mobile support and its return spring ( II) the mobile support comprises a return spring (I2), the travel of the mobile support is limited by a stop (13) fixed on the cylinder head housing.

Une butée (I4) solidaire de la culasse mobile actionne un levier (I5) lors de son recul ce qui à pour effet de déverrouillé le support mobile. A stop (I4) integral with the movable cylinder head actuates a lever (I5) during its recoil which has the effect of unlocking the movable support.

Ce mécanisme de percussion peut être utilisé sur les fusils,les armes de poings, les pistolets de tir de compétitions, il permet aussi de réduire la course de la détente avec un dispositif de percussion à double action.  This percussion mechanism can be used on rifles, handguns, pistols for shooting competitions, it also makes it possible to reduce the stroke of the trigger with a double action percussion device.
