Title
(EN) INTERRUPTED SEMI-AUTOMATIC ACTION FOR FIREARMS
(FR) ACTION SEMI-AUTOMATIQUE INTERROMPUE D'ARMES À FEU
Abstract
(EN)
A firearm with interrupted action includes a barrel, receiver carrying a bolt movable between a forward closed breech position in battery with the barrel and rearward open breech position, a cockable hammer controlled by a trigger, and a bolt release mechanism operably interacting with the bolt. The mechanism may comprise a user-actuated release button and spring-biased disconnect lever coupled thereto and selectively engageable with the hammer. Upon firing, the bolt travels rearward under recoil contacting and partially rotating the disconnect lever to engage the hammer, while simultaneously engaging the hammer which holds the bolt rearward. Actuating the release button fully rotates the disconnect lever to disengage the hammer from the bolt which returns to its forward position via a recoil spring to reclose the breech. A dual interlock safety in one position provided by the release mechanism prevents pulling the trigger and in another position prevents actuating the release button.
(FR)
L'invention concerne une arme à feu à action interrompue comprenant un canon, un récepteur portant un percuteur pouvant se déplacer entre une position avant de culasse fermée en batterie avec le canon et une position arrière de culasse ouverte, un chien basculant commandé par une détente, et un mécanisme de libération de percuteur interagissant de manière fonctionnelle avec le percuteur. Le mécanisme peut comprendre un bouton de libération actionné par l'utilisateur et un levier de désaccouplement sollicité par ressort accouplé à ce dernier et pouvant venir sélectivement en prise avec le chien. Lors d'un tir, le percuteur se déplace vers l'arrière sous l'effet d'un contact de recul et fait pivoter partiellement le levier de désaccouplement pour qu'il vienne en prise avec le chien, tout en venant simultanément en prise le chien qui maintient le percuteur vers l'arrière. L'actionnement du bouton de libération fait tourner complètement le levier de désaccouplement pour désaccoupler le chien du percuteur qui reprend sa position avant par l'intermédiaire d'un ressort de recul de façon à refermer la culasse. Une double sécurité de verrouillage dans une position fournie par le mécanisme de libération empêche l'application d'une traction sur la détente et, dans une autre position, empêche l'actionnement du bouton de libération.
