Description

La présente invention concerne un mécanisme de mise à feu pour armes à feu comprenant une carcasse et une sous-garde, un canon et une culasse mobile dans la carcasse, le mécanisme de mise à feu comprenant un chien commandant le percuteur et monté de manière pivotante dans la carcasse ou dans la sous-garde entre une position "armée" et une position "tombée", un ressort poussant le chien dans sa position tombée et une gâchette pivotante pouvant retenir ce chien en position armée, une détente commandant la gâchette par l'intermédiaire d'un séparateur, un arrêtoir de culasse monté de manière pivotante dans la carcasse ou dans la sous-garde, cet arrêtoir arrêtant dans une position de blocage le mouvement vers l'arrière de la culasse et laissant passer dans une autre position cette culasse, un levier de commande qui coopère avec cet arrêtoir de culasse étant également monté de manière pivotante dans la carcasse ou dans la sous-garde, ce levier de commande pouvant dégager le séparateur de la gâchette retenant le chien de manière à ce que ce séparateur ne puisse plus commander la gâchette.The present invention relates to a firing mechanism for firearms comprising a carcass and a guard, a barrel and a movable breech in the carcass, the firing mechanism including a dog commanding the striker and pivotally mounted in the carcass or in the sub-guard between an "armed" position and a "fallen" position, a spring pushing the dog into its dropped position and a pivoting trigger that can hold this dog in an armed position, a trigger commanding the trigger via a separator, a stopper breech pivotally mounted in the carcass or in the sub-guard, this retainer stopping in a position blocking the backward movement of the cylinder head and letting this cylinder head pass into another position, a control lever which cooperates with this cylinder head retainer also being pivotally mounted in the carcass or in the sub-guard, this control lever being able to release the separator from the trigger retaining the dog so that this separator can no longer control the trigger.

On connaít des carabines à répétition qui possèdent un canon et une culasse mobile ou glissière par exemple à verrouillage rotatif, et qui comprennent un mécanisme de mise à feu du genre susdit.We know repeating rifles that have a barrel and a movable breech or slide for example at rotary lock, and which include a mechanism for firing of the above kind.

L'armement d'une telle carabine se fait par le mouvement d'arrière en avant de la culasse, et son fonctionnement à répétition est également assuré par le mouvement d'arrière en avant puis inversement de la culasse mobile, cette culasse étant actionnée par une manette d'armement. The cocking of such a rifle is done by movement from rear to front of the cylinder head, and its operation at repetition is also ensured by the backward movement forward then vice versa of the movable yoke, this breech being actuated by a cocking lever.

Lorsque l'arme est chargée avec une cartouche dans la chambre de tir et la sûreté est en position "feu", une pression sur la détente agit sur la gâchette par l'intermédiaire du séparateur et le chien est libéré, lançant ainsi le percuteur vers l'amorce de la cartouche chambrée.When the weapon is loaded with a cartridge in the fire chamber and safety is in the "fire" position, a pressure on the trigger acts on the trigger by through the separator and the dog is released, thus launching the striker towards the primer of the cartridge chambered.

Lors de son abattement, le chien agit sur l'arrêtoir de culasse qui est dégagé de la zone de butée de la culasse mobile, permettant à la culasse de passer. Le projectile ayant quitté le canon, l'action du tireur sur la manette d'armement, afin de faire reculer la culasse et d'autres pièces mobiles, entraíne la rotation du verrou et ensuite l'extraction et l'éjection de la douille.During its slaughter, the dog acts on the retainer of breech which is released from the abutment zone of the breech mobile, allowing the cylinder head to pass. The projectile having left the barrel, the action of the shooter on the lever armament, in order to push back the breech and others moving parts, causes the lock to rotate and then extraction and ejection of the sleeve.

Le rabattement du chien et son réarmement sont réalisés par la culasse lors de son mouvement de recul.The folding of the dog and its rearming are carried out by the breech during its backward movement.

Lors du retour vers l'avant de la culasse mobile au moyen de la manette d'armement, une nouvelle cartouche sortie du magasin se trouve sur le transporteur et le culot de cette cartouche interfère avec le verrou de culasse et est entraínée progressivement vers la chambre de tir par ce verrou.When the movable bolt returns to the front by means of the cocking lever, a new cartridge out of the store is on the carrier and the base of this cartridge interferes with the cylinder head latch and is gradually drawn towards the shooting chamber by this lock.

Lorsque le verrou est complètement engagé, la culasse mobile se trouve avant l'arrêtoir de culasse qui a repris sa position de blocage. L'arme est prête à tirer le coup suivant.When the lock is fully engaged, the bolt mobile is located before the bolt retainer which has taken over its blocking position. The gun is ready to fire next.

Il arrive que, après l'armement, le tireur désire désarmer l'arme. Il faut alors enlever la cartouche se trouvant dans la chambre de tir, ce qui n'est possible qu'en pivotant l'arrêtoir de culasse hors position de blocage, ce qui en même temps met le séparateur en une position dans laquelle on ne peut plus commander la gâchette.It happens that after arming, the shooter wishes to disarm tear. It is then necessary to remove the cartridge located in the shooting chamber, which is only possible by pivoting the cylinder head retainer out of the locking position, which same time puts the separator in a position in which we can no longer order the trigger.

Certains mécanismes de mise à feu connus présentent à cette fin une petite poignée fixée au levier de commande coopérant avec l'arrêtoir, cette poignée faisant saillie en dehors de la carcasse, à côté du pontet de sous-garde.Certain known firing mechanisms present this end a small handle attached to the control lever cooperating with the retainer, this handle projecting in outside the carcass, next to the trigger guard.

Le maniement de cette poignée n'est cependant pas facile puisqu'il faut en même temps maintenir l'arme et tirer la culasse vers l'arrière.The handling of this handle is however not easy since at the same time you have to hold the weapon and fire the rear breech.

Le but de la présente invention est de pallier ce désavantage et de procurer un dispositif de mise à feu permettant d'enlever en toute sécurité et d'une manière simple et facile une cartouche chambrée lorsque le dispositif est armé.The purpose of the present invention is to overcome this disadvantage and to provide a firing device allowing to remove safely and in a way simple and easy a chambered cartridge when the device is armed.

Ce but est atteint conformément à l'invention, par le fait que le dispositif de mise à feu comprend un levier de débrayage monté de manière pivotante dans la carcasse ou dans la sous-garde et faisant saillie en dehors de la carcasse et coopérant par une extrémité avec le levier de commande, ce levier de débrayage engageant dans une première position le levier de commande susdit dans la position que ce dernier prend lorsque l'arrêtoir de culasse est en position de blocage, ce levier de débrayage entraínant, par son pivotement de la première position susdite à une deuxième position, dite position de débrayage, le pivotement du levier de commande, de telle manière que l'arrêtoir de culasse pivote hors de sa position de blocage. This object is achieved in accordance with the invention, by the fact that the firing device includes a lever clutch pivotally mounted in the carcass or in the sub-guard and protruding outside the carcass and cooperating at one end with the lever control, this clutch lever engaging in a first position the aforementioned control lever in the position that the latter takes when the breech retainer is in the locked position, this release lever entrainant, by its pivoting from the first position above in a second position, called position of disengagement, pivoting of the control lever, such so that the cylinder head retainer pivots out of its blocking position.

De préférence, le levier de débrayage coopère de telle façon que les deux positions susdites sont des positions stables.Preferably, the release lever cooperates in such a way so that the two above positions are positions stable.

Le levier de commande peut dans ce but être pourvu de deux encoches, une pour chaque position du levier de débrayage, ce levier entrant dans chaque position avec une extrémité dans une des encoches.The control lever can for this purpose be provided with two notches, one for each position of the clutch release lever, this lever entering each position with one end in one of the notches.

L'arrêtoir de culasse peut être pourvu d'au moins une rampe qui, dans la position où elle se trouve lorsque le levier de débrayage se trouve dans la position de débrayage susdit, sans bloquer la culasse coopère avec cette dernière de telle manière que le mouvement de la culasse fait pivoter l'arrêtoir et donc le levier de commande, rompant ainsi le contact entre ce levier de commande et le levier de débrayage et permettant le retour de ce levier de débrayage à sa première position.The cylinder head retainer can be provided with at least one ramp which in the position it is in when the lever in the disengaged position above, without blocking the cylinder head cooperates with the latter in such a way that the movement of the bolt makes pivot the stopper and therefore the control lever, breaking thus the contact between this control lever and the lever release and allowing the return of this lever clutch in its first position.

Dans ce cas un ressort peut agir sur le levier de débrayage, poussant le levier de débrayage vers sa première position.In this case a spring can act on the lever release, pushing the release lever to its first position.

Ainsi ce levier de débrayage retourne automatiquement à sa première position dès qu'il n'est plus retenu par le levier de commande.So this clutch lever automatically returns to its first position as soon as it is no longer held by the lever control.

Pour plus de clarté, un exemple de réalisation d'un dispositif de tir d'une arme à feu selon l'invention est décrit ci-après à titre illustratif et non limitatif, référence étant fait aux dessins annexés, dans lesquels:

  • la figure 1 représente schématiquement une carabine pourvue d'un dispositif de tir selon l'invention;
  • la figure 2 représente à plus grande échelle la partie de l'arme indiquée par F2 à la figure 1;
  • la figure 3 représente schématiquement le mécanisme de mise à feu selon l'invention faisant partie de l'arme des figures 1 et 2, dans la position de tir;
  • la figure 4 représente le mécanisme de la figure 3 mais dans une autre position, c'est-à-dire la position de débrayage;
  • la figure 5 représente le dispositif des figures 3 et 4, mais encore dans une autre position, c'est-à-dire la position après le tir.
    • For greater clarity, an exemplary embodiment of a device for firing a firearm according to the invention is described below by way of illustration and not limitation, reference being made to the appended drawings, in which:
  • Figure 1 schematically shows a rifle provided with a shooting device according to the invention;
  • Figure 2 shows on a larger scale the part of the weapon indicated by F2 in Figure 1;
  • Figure 3 shows schematically the firing mechanism according to the invention forming part of the weapon of Figures 1 and 2, in the firing position;
  • Figure 4 shows the mechanism of Figure 3 but in another position, that is to say the declutching position;
  • 5 shows the device of Figures 3 and 4, but still in another position, that is to say the position after firing.

    • La carabine représentée d'une manière schématique aux figures 1 et 2 comprend essentiellement une carcasse 1, une sous-garde 1' montée sur celle-ci, une crosse 2 montée à une extrémité sur la carcasse 1, un canon 3 avec la chambre de tir, monté sur l'autre extrémité de la carcasse 1 et un garde-main 4, un mécanisme d'armement et un mécanisme de mise à feu.The rifle shown schematically in the Figures 1 and 2 essentially comprises a carcass 1, a sub-guard 1 'mounted thereon, a stock 2 mounted at one end on the carcass 1, a barrel 3 with the chamber firing, mounted on the other end of the carcass 1 and a handguard 4, an arming mechanism and a Firing.

    Le mécanisme d'armement comprend une culasse 5 qui est montée d'une manière mobile sur la carcasse 1 et commande un verrou rotatif pouvant fermer la chambre de tir, chambre dans laquelle une cartouche peut être introduite à partir d'un chargeur 6.The cocking mechanism comprises a bolt 5 which is movably mounted on the carcass 1 and controls a rotary lock which can close the firing chamber, chamber into which a cartridge can be inserted from a charger 6.

    Le mécanisme de mise à feu qui est représenté plus en détail aux figures 3 à 5 comprend un chien 7 monté de manière pivotante dans la sous-garde 1', représentée en traits mixtes, autour d'un axe transversal 8 entre une position dite "armée", telle que représentée aux figures 3 et 4 et une position dite "tombée", représentée à la figure 5, un ressort 9 dont seulement une partie est représentée aux figures 3 à 5, poussant le chien 7 dans sa position tombée, ce chien 7 commandant le percuteur 10 qui est uniquement représenté à la figure 5.The firing mechanism which is shown more in detail in Figures 3 to 5 includes a dog 7 mounted from pivotally in the sub-guard 1 ', shown in mixed lines, around a transverse axis 8 between a so-called "armed" position, as shown in Figures 3 and 4 and a so-called "fallen" position, represented in the figure 5, a spring 9 of which only a part is shown in Figures 3 to 5, pushing the dog 7 into its position fallen, this dog 7 commanding the striker 10 which is only shown in Figure 5.

    Une gâchette 11 est également montée de manière pivotante autour d'un axe transversal 12 et peut, dans une position dans laquelle elle est d'ailleurs poussée par un ressort 13, retenir le chien 7 en position armée.A trigger 11 is also pivotally mounted about a transverse axis 12 and can, in a position in which it is also pushed by a spring 13, hold the dog 7 in the armed position.

    Une détente 14 commandant la gâchette 11 par l'intermédiaire d'un levier ou séparateur 15, peut pivoter autour d'un axe transversal 16 dans la sous-garde 1'. Le séparateur 15 est fixé à la détente par un axe transversal 17 et est poussé vers la position représentée aux figures 3 à 5 par un ressort 18.A trigger 14 controlling the trigger 11 via of a lever or separator 15, can pivot around of a transverse axis 16 in the sub-guard 1 '. The separator 15 is fixed to the trigger by a transverse axis 17 and is pushed to the position shown in Figures 3 to 5 by a spring 18.

    Le mécanisme de mise à feu comprend en outre un arrêtoir de culasse 19 monté de manière pivotante dans la sous-garde 1', autour du même axe transversal 8 que le chien 7.The firing mechanism further includes a stopper for cylinder head 19 pivotally mounted in the sub-guard 1 ', around the same transverse axis 8 as the dog 7.

    Cet arrêtoir de culasse 19, arrête dans sa position de blocage représentée à la figure 3, le mouvement vers l'arrière de la culasse 5 et laisse passer dans une autre position, telle que représentée aux figures 4 et 5, cette culasse 5. Cet arrêtoir de culasse 19 est enfourché par son extrémité arrière par l'extrémité avant d'un levier de commande 20 qui est également monté de manière pivotante autour d'un axe transversal 21 sur la carcasse 1 ou la sous-garde 1'.This cylinder head retainer 19 stops in its position blocking shown in Figure 3, the movement towards the rear of the cylinder head 5 and lets pass into another position, as shown in Figures 4 and 5, this cylinder head 5. This cylinder head retainer 19 is straddled by its rear end by the front end of a lever control 20 which is also pivotally mounted around a transverse axis 21 on the carcass 1 or the sub-guard 1 '.

    Le sommet de l'extrémité avant de l'arrêtoir de culasse 19 est pourvu d'un système de rampes 22 et 23 descendant respectivement vers l'avant et vers l'arrière. The apex of the front end of the cylinder head retainer 19 is fitted with a descending ramp system 22 and 23 forward and backward respectively.

    En arrière par rapport à son axe 21, le levier de commande 20 est pourvu d'une excroissance centrale 24 pouvant s'appuyer sur le séparateur 15 et à l'aide de laquelle ce levier de commande 20 peut dégager le séparateur 15 de la gâchette 11 de manière à ce que ce séparateur 15 ne puisse plus commander la gâchette 11, tel que représenté à la figure 4.Back with respect to its axis 21, the control lever 20 is provided with a central projection 24 which can lean on the separator 15 and using which this control lever 20 can release the separator 15 from the trigger 11 so that this separator 15 cannot no longer order trigger 11, as shown in figure 4.

    Le levier de commande 20 présente près de son extrémité avant deux encoches 25 et 26 dans son bord inférieur, l'encoche 25 située du côté de l'axe 21 par rapport à l'autre étant plus profonde.The control lever 20 has near its end before two notches 25 and 26 in its lower edge, the notch 25 located on the side of the axis 21 relative to the other being deeper.

    Un levier de débrayage 27, situé à droite du pontet 28 de la sous-garde 1' peut entrer par son extrémité supérieure pointue dans une des encoches 25 ou 26. Ce levier de débrayage 27 pivote autour d'un axe transversal 29 monté dans la sous-garde 1' entre une première position verticale telle que représentée aux figures 3 et 5 et une position inclinée telle que représentée à la figure 4.A release lever 27, located to the right of the trigger guard 28 of the sub-guard 1 'can enter through its upper end pointed in one of the notches 25 or 26. This lever declutching 27 pivots about a transverse axis 29 mounted in the sub-guard 1 'between a first vertical position as shown in Figures 3 and 5 and a position inclined as shown in Figure 4.

    Un ressort 30 s'appuyant sur la sous-garde 1' pousse le levier de débrayage 27 vers sa première position verticale. Les dimensions de ce levier de débrayage 27 et des encoches 25 et 26 sont telles que l'arrêtoir de culasse 19 ne peut se trouver dans sa position de blocage que lorsque l'extrémité pointue du levier de débrayage 27 se trouve dans l'encoche 25, tandis que lorsque cette extrémité se trouve dans l'encoche 26, l'arrêtoir de culasse 19 se trouve dans une position intermédiaire, c'est-à-dire sans bloquer la culasse 5, mais quand même avec une rampe 22 encore dans la trajectoire de la culasse 5. A spring 30 resting on the sub-guard 1 'pushes the clutch release lever 27 to its first vertical position. The dimensions of this clutch release lever 27 and the notches 25 and 26 are such that the cylinder head retainer 19 cannot be in its locked position only when the pointed end of the clutch release lever 27 is in the notch 25, while when this end is located in the notch 26, the cylinder head retainer 19 is found in an intermediate position, i.e. without block the cylinder head 5, but still with a ramp 22 still in the trajectory of the cylinder head 5.

    Près de son axe 8, le chien 7 possède une saillie 31, à laquelle est d'ailleurs fixé le ressort 9. Cette saillie 31 bute contre l'arrêtoir de culasse 19 lorsque ce chien 7 passe de sa position armée à sa position retombée.Near its axis 8, the dog 7 has a projection 31, at which is also fixed the spring 9. This projection 31 abuts the breech retainer 19 when this dog 7 goes from its armed position to its fallen position.

    Pour des raisons de clarté, l'arrêtoir de culasse 19, le levier de commande 20 et le levier de débrayage 27 ont été représentés aux figures 3 à 5 en traits pleins tandis que les autres éléments du mécanisme de mise à feu ont été représentés en traits discontinus.For reasons of clarity, the cylinder head retainer 19, the control lever 20 and release lever 27 have been shown in Figures 3 to 5 in solid lines while the other elements of the firing mechanism were shown in broken lines.

    Le mécanisme de mise à feu décrit ci-devant fonctionne comme suit:The firing mechanism described above works as following:

    Dans la position "prête à tirer", représentée à la figure 3, le chien 7 est en position armée et donc accroché par son extrémité dans le bec de la gâchette 11 et le séparateur 15 est en contact avec la gâchette 11.In the "ready to fire" position, shown in the figure 3, the dog 7 is in the armed position and therefore hooked by its end in the tip of the trigger 11 and the separator 15 is in contact with trigger 11.

    Le levier de débrayage 27 entre par une extrémité dans l'encoche 25, ce qui veut dire que l'arrêtoir de culasse 19 est en position de bloquage et bloque la culasse 5 dans sa position avant. Le verrou ferme la chambre de tir dans laquelle se trouve une cartouche.The release lever 27 enters at one end into the notch 25, which means that the cylinder head retainer 19 is in the locking position and locks the cylinder head 5 in its forward position. The lock closes the firing chamber in which is a cartridge.

    Pour pouvoir extraire cette cartouche de la chambre de tir sans tirer, il suffit de faire pivoter à la main le levier de débrayage 27 jusque dans sa position inclinée de débrayage, c'est-à- dire avec son extrémité dans l'encoche 26, comme représenté à la figure 4.To be able to extract this cartridge from the shooting chamber without pulling, simply rotate the lever by hand clutch 27 to its inclined position declutching, i.e. with its end in the notch 26, as shown in FIG. 4.

    Le pivotement susdit du levier de débrayage 27 jusque dans sa position de débrayage entraíne un pivotement du levier de commande 20 et par conséquent également de l'arrêtoir de culasse 19 jusque dans sa position intermédiaire susdite.The abovementioned pivoting of the clutch release lever 27 into its declutching position causes the lever to pivot 20 and therefore also of the cylinder head 19 to its above intermediate position.

    Lors de son pivotement, le levier de commande 20 appuie avec l'excroissance 24 sur le séparateur 15 qui est ainsi mis dans une position où il est dégagé de la gâchette 11 et ne peut plus commander cette dernière.During its pivoting, the control lever 20 presses with the protrusion 24 on the separator 15 which is thus put in a position where it is released from trigger 11 and can no longer order the latter.

    Un tir n'est plus possible et, comme l'arrêtoir de culasse 19 ne bloque plus la culasse 5, cette dernière peut en toute sécurité être tirée vers l'arrière à l'aide de la manette d'armement 32, ce recul entraínant le déverrouillage et l'extraction de la cartouche non tirée.A shot is no longer possible and, like the breech catch 19 no longer blocks the cylinder head 5, the latter can safely be pulled back using the cocking lever 32, this setback causing the unlocking and extraction of the cartridge not pulled.

    Etant donné que le levier de débrayage 27 engage l'encoche 26, il se trouve dans une position stable et ne doit pas être maintenu manuellement dans cette position.Since the release lever 27 engages the notch 26, it is in a stable position and must not be held manually in this position.

    Puisque l'encoche 26 est peu profonde, le moindre pivotement du levier de commande 20 aura comme conséquence que le levier de débrayage 27 retourne à sa position verticale sous l'action du ressort 30.Since notch 26 is shallow, the slightest pivoting the control lever 20 will result the release lever 27 returns to its position vertical under the action of spring 30.

    Or, lors du mouvement susdit vers l'arrière de la culasse 5, cette dernière fait pivoter légèrement l'arrêtoir de culasse 19 qui se trouve en position intermédiaire, causant le pivotement susdit du levier de commande 20, de sorte qu'après le retour en avant de la culasse 5, ce dernier est bloqué à nouveau et le mécanisme de mise à feu se trouve à nouveau dans la position représentée à la figure 3.However, during the aforesaid movement towards the rear of the cylinder head 5, the latter slightly swivels the retainer of cylinder head 19 which is in the intermediate position, causing the aforementioned pivoting of the control lever 20, so that after the return to the front of the cylinder head 5, the latter is blocked again and the firing mechanism is at again in the position shown in Figure 3.

    A la figure 5, ce dernier mécanisme est représenté après un tir, et donc avec le chien 7 abattu. In Figure 5, the latter mechanism is shown after a shot, and therefore with the dog 7 shot.

    Sous l'action de la détente 14 et par l'intermédiaire du séparateur 15 et de la gâchette 11, le chien 7 a été libéré et a repoussé le percuteur 10. Lors de ce mouvement du chien 7, la saillie 31 a buté contre l'arrêtoir de culasse 19 et a fait pivoter ce dernier de sorte que l'extrémité avec les rampes 22 et 23 est dans sa position la plus basse. De ce fait le levier de commande 20 a dégagé par l'intermédiaire de l'excroissance 24 le séparateur 15 de la gâchette 11.Under the action of trigger 14 and through the separator 15 and trigger 11, dog 7 has been released and pushed back the striker 10. During this movement of the dog 7, the projection 31 abutted against the breech retainer 19 and rotated the latter so that the end with ramps 22 and 23 is in its most low. Thereby the control lever 20 released by through the protrusion 24 the separator 15 of the trigger 11.

    Le levier de débrayage 27 se trouve en position verticale, mais sans contact avec le levier de commande 20.The release lever 27 is in the vertical position, but without contact with the control lever 20.

    Le chien 7 est rabattu en position armée par le recul de la culasse 5, le retour en avant de cette culasse 5 réalisant de manière classique l'introduction d'une cartouche dans la chambre de tir et le verrouillage de cette chambre.The dog 7 is folded back into the armed position by the retreat of the cylinder head 5, the return forward of this cylinder head 5 realizing conventionally the introduction of a cartridge into the firing chamber and locking that chamber.

    Bien que dans l'exemple décrit ci-devant le chien 7, l'arrêtoir de culasse 19, le levier de commande 20 et le levier de débrayage 27 sont montés dans la sous-garde 1', il est évident que dans une autre forme de réalisation un ou plusieurs de ces éléments peuvent être montés dans la carcasse 1.Although in the example described above dog 7, the cylinder head retainer 19, the control lever 20 and the clutch release lever 27 are mounted in sub-guard 1 ', it is obvious that in another embodiment a or more of these can be mounted in the carcass 1.

    La sous-garde 1' peut d'ailleurs dans une forme de réalisation faire partie intégrante de la carcasse 1.The sub-guard 1 'can moreover in a form of realization be an integral part of the carcass 1.

    Claims (5)

    1. Firing mechanism for fire arms, comprising a casing (1) and a trigger guard (1'), a barrel (3) and a mobile bolt (5) in the casing (1), whereby the firing mechanism comprises a hammer (7) controlling the striker (10) and which is mounted in a revolving manner in the casing (1) or in the trigger guard (1') between a 'cocked' and a 'tumbled' position, a spring (9) pushing the hammer (7) in its tumbled position and a revolving tumbler (11) which can retain said hammer (7) in its cocked position, a trigger (14) controlling the tumbler (11) by means of a separator (15), a bolt stop (19) mounted in a revolving manner in the casing (1) or the trigger guard (1'), whereby said stop (19) stops the backward movement of the bolt (5) in a locked position and makes the bolt (5) assume another position, a control lever (20) which co-operates with said bolt stop (19) which is also mounted in a revolving manner in the casing (1) or in the trigger guard (1'), whereby said control lever (20) can disengage the separator (15) from the tumbler (11) retaining the hammer (7), such that the separator (15) can no longer control the tumbler (11), characterised in that the firing device contains a release lever (27) mounted in a revolving manner in the casing (1) or in the trigger guard (1') and protruding outside the casing (1) and co-operating with one far end with the control lever (20), whereby, in a first position, this release lever (27) engages said control lever (20) in the position which the latter assumes when the bolt stop (19) is in the locked position, whereby this release lever (27) makes the control lever (20) revolve as it revolves from said first position into a second position, what is called the release position, such that the bolt stop (19) revolves out of its locking position.
    2. Mechanism according to claim 1, characterised in that the release lever (27) co-operates such that the two above-mentioned positions are stable positions.
    3. Mechanism according to claim 2, characterised in that the control lever (20) is provided with two notches (25-26), one for each position of the release lever (27), whereby this lever (27) penetrates with one far end in either of the notches (25-26) in each position.
    4. Mechanism according to any of the preceding claims, characterised in that the bolt stop (19) is provided with at least one ramp (22-23) which, in the position in which it is situated when the release lever (27) is situated in the above-mentioned release position, co-operates with the bolt (5) without locking it, such that the movement of the bolt (5) makes the stop (19) and thus the control lever (20) revolve, thus breaking the contact between said control lever (20) and the release lever (27) and making it possible for said release lever (27) to return into its first position.
    5. Mechanism according to claim 4, characterised in that it comprises a spring (30) which acts on the release lever (27), pushing the release lever (27) into its first position.
