Abstract

The firing mechanism comprises a trigger (1) operating a hammer release catch (4) via a linkage (3). It has a lock in the form of a lug (10) projecting from the linkage to prevent any rotation of the catch except by pulling the trigger, when the lug on the linkage interacts with the catch via a drive lever (12). The catch and its drive lever rotate about the same axis (6), the lever having two arms (13,14) which interact with the lug and catch respectively. The lever can also have an extension which interacts with the moving element of an electromagnetic actuator controlled by an electrical signal.

Description

La présente invention concerne un dispositif de déclenchement de tir à sûreté totale pour une arme à feu individuelle de petit ou de moyen calibre, notamment pour une arme comprenant un dispositif de déclenchement électrique de tir.The present invention relates to a device for triggering full safety fire for a firearm individual of small or medium caliber, especially for a weapon including an electric triggering device shoot.

Les dispositifs de déclenchement actuels prévoient une sûreté sur la détente de l'arme, qui est combinée à un blocage du percuteur ou du marteau. La sûreté sur la détente consiste soit en un blocage mécanique au moyen d'un ergot, c'est à dire que l'on interdit toute rotation de la détente, soit à rendre la détente indépendante de l'arme. Le blocage du percuteur interdit toute percussion de l'amorce, et le blocage du marteau interdit son action directe sur le percuteur. Dans certains cas, le marteau peut pivoter, mais la sûreté entraíne alors le martèlement d'une autre pièce que le percuteur.Current trip devices provide for a safety on the trigger of the weapon, which is combined with a blocking of the striker or hammer. Safety on relaxation either consists of a mechanical blocking by means of a lug, that is to say that any rotation of the trigger is prohibited, either to make the trigger independent of the weapon. The blocking of the striker prohibits any percussion of the primer, and the blocking the hammer prohibits its direct action on the striker. In some cases, the hammer can rotate, but safety then leads to the hammering of another part than the striker.

Ces dispositifs présentent un certain nombre d'inconvénients. Ainsi, la sécurité offerte par une sûreté de détente seule est relative, car rien n'interdit le pivotement de la gâchette sous l'effet d'un choc, par exemple, entraínant la libération du marteau. Si on adopte une sûreté de marteau ou de percuteur, il faut que le tireur effectue une action supplémentaire pour l'effacer. La sécurité est totale, mais l'effacement de la sûreté n'est pas automatique.These devices have a number disadvantages. Thus, the security offered by a security of relaxation alone is relative, because nothing prevents pivoting trigger trigger, for example, causing the release of the hammer. If we adopt a security hammer or striker, the shooter must perform an additional action to erase it. Security is total, but the erasure of the security is not automatic.

On connaít d'autre part des armes de petit ou moyen calibre dotées d'un dispositif de déclenchement électrique du tir. Le brevet US2780882 décrit ainsi une arme à feu individuelle dont le dispositif de déclenchement est électrique. Ce dispositif comprend une détente qui ferme un interrupteur alimentant en énergie un électro aimant.We also know small and medium weapons caliber fitted with an electrical trip device shoot. The patent US2780882 thus describes a firearm individual whose triggering device is electric. This device includes a trigger which closes a switch supplying energy to an electromagnet.

En cas de défaillance de l'électro-aimant, une course supérieure de la détente provoque un déclenchement mécanique du tir.In the event of failure of the electromagnet, one stroke trigger triggers a mechanical trigger of shooting.

On connaít également par le brevet européen EP587504 un dispositif de déclenchement électrique du tir dans lequel le tireur active en actionnant la détente un dispositif de détection de cible.Also known by European patent EP587504 a electric triggering device in which the active shooter by operating the trigger a target detection.

Le tir est déclenché alors automatiquement par un électro aimant lorsqu'une cible coïncide avec un point visé.The shot is then triggered automatically by an electro magnet when a target coincides with a target point.

Ces dispositifs connus ne comprennent pas de sécurité totale. Ainsi les vibrations et chocs risquent de provoquer la libération du percuteur.These known devices do not include security total. Thus vibrations and shocks may cause release of the striker.

De plus les dispositifs de déclenchement électrique connus sont encombrants, complexes et difficiles à mettre en place à l'intérieur d'une arme à déclenchement mécanique existante sans modifier complètement le dispositif de déclenchement mécanique de cette dernière.In addition, the electrical trip devices known are bulky, complex and difficult to implement place inside a mechanically triggered weapon existing without completely modifying the mechanical release of the latter.

Un premier but de la présente invention est de pallier les inconvénients des mécanismes décrits ci-dessus en proposant un dispositif de déclenchement prévoyant une sûreté de détente à laquelle on associe une sûreté totale dont l'effacement est automatique lors du tir.A first object of the present invention is to alleviate the disadvantages of the mechanisms described above in proposing a trigger device providing safety relaxation to which we associate total safety, erasure is automatic when firing.

Un deuxième but de la présente invention est de proposer un dispositif de déclenchement de tir à sûreté totale plus particulièrement adapté à une arme à déclenchement électrique.A second object of the present invention is to propose a total safety firing trigger plus particularly suitable for a trigger weapon electric.

Ce dispositif permet d'assurer un déclenchement électrique du tir tout en conservant les organes de déclenchement mécanique d'une arme donnée. Le déclenchement mécanique pouvant en outre être mis en oeuvre par le tireur selon ses besoins opérationnels.This device ensures triggering electric fire while retaining the organs of mechanical triggering of a given weapon. The triggering mechanical which can also be implemented by the shooter according to its operational needs.

Le dispositif de déclenchement électrique selon l'invention est à la fois simple et compact et il ne nécessite que peu d'énergie électrique pour fonctionner.The electrical trip device according to the invention is both simple and compact and it does not requires little electrical power to operate.

A cet effet, l'invention propose un dispositif de déclenchement de tir pour une arme à feu individuelle de petit ou de moyen calibre comportant une détente actionnant une gâchette au moyen d'une tringle pour libérer un marteau de percussion, la détente étant elle même soumise à l'action d'une sûreté de détente, dispositif caractérisé en ce qu'il comprend un moyen de blocage solidaire de la tringle, moyen constitué par un ergot en saillie par rapport à la tringle et en appui sur la gâchette pour interdire la rotation de celle-ci et dont l'effacement est commandé automatiquement par le mouvement de la détente, la gâchette étant par ailleurs attelée à un levier d'entraínement coopérant avec l'ergot pour actionner la gâchette.To this end, the invention provides a device for firing trigger for an individual firearm's small or medium caliber with trigger trigger a trigger by means of a rod to release a hammer percussion, the trigger itself being subjected to the action safety trigger, device characterized in that it comprises a locking means integral with the rod, means constituted by a lug projecting from the rod and pressing the trigger to prevent it from rotating and whose erasure is automatically controlled by the movement of the trigger, the trigger also being coupled to a drive lever cooperating with the lug to operate the trigger.

Selon d'autres caractéristiques de l'invention :

  • la gâchette et le levier sont montés rotatifs autour d'un même axe de rotation,
  • l'ergot est mobile entre les extrémités libres de la gâchette et du levier d'entraínement.
According to other characteristics of the invention:
  • the trigger and the lever are mounted to rotate about the same axis of rotation,
  • the lug is movable between the free ends of the trigger and the drive lever.

Selon un exemple de réalisation, le levier d'entraínement comprend deux branches dont la première branche coopère avec l'ergot et la seconde branche avec la gâchette pour entraíner celle-ci par l'action de l'ergot sur la première branche.According to an exemplary embodiment, the drive lever comprises two branches, the first branch of which cooperates with the lug and the second branch with the trigger to train this by the action of the lug on the first branch.

Selon un autre mode de réalisation de l'invention, le levier d'entraínement est prolongé par une queue sur laquelle vient prendre appui un élément mobile d'un actionneur du type électromagnétique pour faire pivoter le levier lors d'un déclenchement électrique du tir et libérer ainsi le marteau de percussion.According to another embodiment of the invention, the drive lever is extended by a tail on which comes to bear a mobile element of an actuator of the type electromagnetic to rotate the lever during a electric triggering of the shot and thus releasing the hammer percussion.

Selon une autre caractéristique de ce mode de réalisation l'actionneur est activé par un signal électrique de commande qui est validé par le tireur en faisant pivoter la détente suivant une course nécessaire pour effacer le moyen de blocage en rotation de la gâchette.According to another characteristic of this embodiment the actuator is activated by an electrical control signal which is validated by the shooter by rotating the trigger following a course necessary to erase the means of blocking in rotation of the trigger.

Selon une autre caractéristique, le dispositif de déclenchement mécanique du tir est validé lorsque la détente a effectué une course supérieure à la course.According to another characteristic, the device for mechanical triggering of the shot is validated when the trigger ran a race longer than the race.

Un tout premier avantage de la présente invention réside dans la simplicité de réalisation du dispositif qui n'entraíne pas une modification du fonctionnement de l'arme et qui s'intègre en ne modifiant qu'un nombre minimum de pièces.A very first advantage of the present invention resides in the simplicity of realization of the device which does not modify the functioning of the weapon and which is integrated by modifying only a minimum number of rooms.

Un autre avantage de la présente invention réside dans l'effacement de la sûreté par une action faible du tireur sur la détente.Another advantage of the present invention lies in the erasure of the safety by a weak action of the shooter on relaxation.

Un autre avantage encore de la présente invention réside dans le blocage mécanique de la gâchette rendant la sûreté totale quelles que soient les sollicitations, chocs ou vibrations par exemple, qui peuvent être exercés sur la gâchette.Yet another advantage of the present invention is in the mechanical blocking of the trigger making safety total whatever the stresses, shocks or vibrations for example, which can be exerted on the trigger.

Les figures 1 à 4 montrent en partie un mécanisme classique de percussion d'une arme à feu individuelle de petit ou de moyen calibre.Figures 1 to 4 partially show a mechanism percussion classic of an individual firearm of small or medium caliber.

L'arme représentée sur la figure 1 comprend notamment une détente 1 qui est articulée en rotation autour d'un axe supporté par le corps de l'arme et entraínant par sa rotation une tringle 3 en translation, qui commande une gâchette et un marteau 5 de percussion. Sur la figure 2, la gâchette référencée 4 est montée articulée autour d'un axe 6 supporté par le corps de l'arme et est ramenée constamment dans une position de blocage du marteau 5 au moyen d'un ressort de rappel 7. Le marteau 5 est monté articulé autour d'un axe 8 supporté par le corps de l'arme. La gâchette 4 interdit la rotation du marteau 5 par l'intermédiaire d'un système ergot-encoche connu en soi.The weapon shown in Figure 1 includes in particular a trigger 1 which is articulated in rotation about an axis supported by the body of the weapon and driving by its rotation a rod 3 in translation, which controls a trigger and a percussion hammer 5. In Figure 2, the trigger referenced 4 is mounted articulated around a supported axis 6 by the body of the weapon and is constantly brought back into a hammer blocking position 5 by means of a spring reminder 7. The hammer 5 is mounted articulated around an axis 8 supported by the body of the weapon. Trigger 4 prohibits hammer 5 rotation via a lug-notch system known per se.

Selon l'invention, la tringle 3 est munie d'un moyen de blocage 9 qui est ici constitué par un ergot 10 disposé en saillie sur la tringle 3. Cet ergot 10 est placé de façon que dans la position de repos, la détente 1 est bloquée par la sûreté de détente 11, qui est représentée schématiquement sur la figure 2 par un obstacle interdisant toute rotation de ladite détente. L'ergot 10 vient en appui sur la gâchette 4 et se coince contre le corps de l'arme (partie hachurée) interdisant alors la rotation de celle-ci et par suite un départ accidentel du coup de feu.According to the invention, the rod 3 is provided with a means of blocking 9 which is here constituted by a lug 10 arranged in projection on the rod 3. This lug 10 is placed so that in the rest position, the trigger 1 is blocked by the trigger safety 11, which is shown diagrammatically on Figure 2 by an obstacle preventing any rotation of said trigger. The lug 10 comes to rest on the trigger 4 and gets stuck against the body of the weapon (hatched part) prohibiting then the rotation of this one and consequently a accidental departure of the shot.

Selon l'invention, on prévoit également un levier d'entraínement 12 attelé à la gâchette 4. Ce levier 12 se présente suivant une forme en V et est monté articulé autour de l'axe de rotation 6 de la gâchette 4. Ce levier 12 comprend une première branche 13 qui est destinée à coopérer avec l'ergot 10, et une seconde branche 14 qui est destinée à coopérer avec la gâchette 4 par l'intermédiaire de leurs extrémités libres. La branche 14 du levier 12 comprend un moyen d'accrochage, tel qu'une griffe, sur la gâchette 4. Ainsi, la rotation du levier 12 entraíne la rotation ultérieure de la gâchette 4 et par la suite la libération du marteau 5. Lorsque la sûreté de détente 11 est enlevée ou effacée, le mouvement de la détente 1 est possible. La course morte de la détente 1 correspond sensiblement à la distance séparant l'ergot 10 de la première branche 13 du levier 12, cette course étant utilisée pour décaler l'ergot 10 et permettre la rotation de la gâchette 4 et donc le départ du coup.According to the invention, a lever is also provided drive 12 coupled to the trigger 4. This lever 12 is has a V shape and is mounted hinged around of the axis of rotation 6 of the trigger 4. This lever 12 comprises a first branch 13 which is intended to cooperate with lug 10, and a second branch 14 which is intended for cooperate with trigger 4 through their free ends. The branch 14 of the lever 12 comprises a attachment means, such as a claw, on the trigger 4. Thus, the rotation of the lever 12 causes the rotation subsequent trigger 4 and thereafter releasing the hammer 5. When the trigger 11 is removed or cleared, the movement of trigger 1 is possible. The race still life of trigger 1 corresponds substantially to the distance separating the lug 10 from the first branch 13 of the lever 12, this stroke being used to offset the lug 10 and allow the rotation of the trigger 4 and therefore the departure of the stroke.

La figure 2 illustre le mécanisme dans une position de repos où l'ergot 10 est en contact avec la gâchette 4 pour réaliser une immobilisation mécanique de cette dernière quelles que soient les sollicitations auxquelles elle pourrait être soumise. La gâchette 4 est ainsi coincée par l'ergot 10 contre le corps de l'arme au niveau de la partie assurant le guidage de la tringle 3. La rotation de la gâchette 4 est donc impossible.Figure 2 illustrates the mechanism in a position of rest where the lug 10 is in contact with the trigger 4 for perform a mechanical immobilization of the latter whatever the requests to which it could be submitted. The trigger 4 is thus jammed by lug 10 against the body of the weapon at the level of the part guiding the rod 3. The rotation of the trigger 4 is therefore impossible.

La figure 3 illustre le mécanisme dans une position "prêt au tir" dans laquelle la détente 1 ayant été libérée est actionnée pour déplacer la tringle 3 d'une distance d séparant les extrémités libres de la gâchette 4 et de la première branche 13 du levier d'entraínement 12. L'ergot 10 est alors effacé par rapport à la gâchette 4 et, dans cette position avancée de la tringle 3, la rotation de la gâchette 4 est autorisée. L'effacement de l'ergot 10 constituant la sûreté s'effectue donc pendant la course de la détente de manière automatique sans intervention supplémentaire du tireur.Figure 3 illustrates the mechanism in a "ready" position firing "in which the trigger 1 having been released is actuated to move the rod 3 by a distance d separating the free ends of trigger 4 and the first branch 13 of the drive lever 12. The lug 10 is then deleted relative to trigger 4 and, in this advanced position of the rod 3, the rotation of the trigger 4 is allowed. The erasure of the lug 10 constituting the safety therefore takes place during the detent automatically without additional intervention from the shooter.

La figure 4 illustre le mécanisme dans la position tir où le tireur a poursuivi son action sur la détente 1 en actionnant en rotation la première branche 13 du levier d'entraínement 12 par l'intermédiaire de l'ergot 10. Cette translation supplémentaire de l'ergot 10 entraíne de manière concomitante l'accrochage de la gâchette 4 par la seconde branche 14 du levier 12 et par suite la rotation simultanée du levier 12 et de la gâchette 4. La gâchette libère ainsi le marteau 5 qui entame sa rotation suivant la flèche F1 pour déclencher le tir.Figure 4 illustrates the mechanism in the firing position where the shooter continued his action on the trigger 1 in actuating in rotation the first branch 13 of the lever 12 through the lug 10. This additional translation of the lug 10 drives so concomitant the triggering of the trigger 4 by the second branch 14 of lever 12 and consequently the simultaneous rotation lever 12 and trigger 4. The trigger thus releases the hammer 5 which begins its rotation according to arrow F1 for fire.

La figure 5 montre la position relative au repos de la gâchette 4, du levier 12 et de l'ergot 10 qui vient en appui sur la gâchette 4 et se coince contre le corps A de l'arme.Figure 5 shows the relative position at rest of the trigger 4, lever 12 and lug 10 which comes to bear on trigger 4 and gets stuck against body A of the weapon.

Les figures 6 à 8 illustrent un deuxième mode de réalisation d'un dispositif de déclenchement de tir selon l'invention.Figures 6 to 8 illustrate a second mode of production of a triggering device according to the invention.

Ce dispositif comprend comme celui décrit précédemment une détente 1 qui entraíne une tringle 3 portant un ergot 10 venant en appui sur la gâchette 4 et interdisant ainsi la rotation de celle ci et un départ accidentel du coup de feu.This device includes, like that described above a trigger 1 which leads to a rod 3 carrying a lug 10 coming to rest on trigger 4 and thus preventing rotation of this one and an accidental departure of the shot.

La détente 1 est là encore normalement bloquée par une sûreté de détente (non représentée).The trigger 1 is again normally blocked by a trigger safety (not shown).

Lorsque le dispositif de déclenchement du tir est dans une position de repos (figure 6), l'ergot 10 porté par la tringle 3 est en appui sur la gâchette 4 pour interdire sa rotation. L'ergot 10 constitue un dispositif de sûreté totale qui permet d'éviter un déclenchement accidentel du tir qui pourrait intervenir par suite du dégagement de l'ergot 4a de la gâchette 4 hors de l'encoche 5a du marteau 5 (figure 7). Cet ensemble constitue un dispositif de déclenchement mécanique du tir (M).When the triggering device is in a rest position (Figure 6), the lug 10 carried by the rod 3 is supported on the trigger 4 to prohibit its rotation. Lug 10 constitutes a total safety device which prevents accidental firing which could occur as a result of the release of lug 4a from the trigger 4 out of the notch 5a of the hammer 5 (FIG. 7). This set constitutes a triggering device shooting mechanics (M).

Le dispositif de déclenchement selon ce mode de réalisation de l'invention diffère du précédent en ce que le levier 12, vers son extrémité opposée à ses deux branches 13 et 14, se prolonge par une queue 24 qui vient jusqu'au voisinage d'une tige de commande 22 d'un actionneur 20 qui constitue un dispositif de déclenchement électrique du tir (E).The triggering device according to this mode of realization of the invention differs from the previous one in that the lever 12, towards its end opposite to its two branches 13 and 14, is extended by a tail 24 which comes up to vicinity of a control rod 22 of an actuator 20 which constitutes an electric triggering device (E).

L'actionneur 20 est par exemple constitué par un électro-aimant. Il comprend un équipage mobile formé par la tige 22 qui est mobile entre une position de repos et une position active lorsque l'actionneur 20 reçoit un signal électrique de commande S, provenant par exemple d'un détecteur de cible.The actuator 20 is for example constituted by an electromagnet. It includes a mobile assembly formed by the rod 22 which is movable between a rest position and a position active when actuator 20 receives an electrical signal from command S, for example from a target detector.

La tige 22 est destinée à venir prendre appui sur la queue 24 pour forcer le levier 12 à pivoter autour de son axe 6. La branche 14 du levier 12 entraíne en rotation la gâchette 4 qui libère le marteau 5 par suite du dégagement de l'ergot 4a de la gâchette 4 hors de l'encoche 5a du marteau 5.The rod 22 is intended to come to bear on the shank 24 to force lever 12 to pivot about its axis 6. The branch 14 of the lever 12 rotates the trigger 4 which releases the hammer 5 as a result of the release of trigger pin 4a of trigger 4 out of notch 5a of hammer 5.

Le dispositif de déclenchement selon ce mode de réalisation de l'invention peut fonctionner, au choix du tireur, d'une façon mécanique ou électrique.The triggering device according to this mode of realization of the invention can work, at the choice of shooter, mechanically or electrically.

Lorsqu'un déclenchement mécanique du tir est souhaité (figures 6 et 7), le tireur efface tout d'abord la sécurité de détente pour permettre à celle-ci de pivoter autour de son axe 2. Ensuite le tireur fait pivoter la détente 1 ce qui entraíne un déplacement en translation de la tringle 3 de manière à ce que l'ergot 10 se rapproche de l'extrémité libre de la branche 13 du levier 12. Après une course C1 de la détente 1, l'ergot 10 est au contact de la branche 13 du levier 12 et entraíne en rotation la gâchette 4 par l'intermédiaire de sa branche 14 qui est en prise avec la gâchette 4. L'ergot 4a de la gâchette 4 se dégage de l'encoche 5a du marteau 5 qui est alors dans une position armée. Le marteau 5 est alors libéré pour venir percuter une amorce, d'une façon connue en soi.When mechanical triggering of fire is desired (Figures 6 and 7), the shooter first clears the security trigger to allow it to pivot around its axis 2. Then the shooter rotates the trigger 1 which causes a displacement in translation of the rod 3 of so that the lug 10 approaches the free end of branch 13 of lever 12. After a stroke C1 of the trigger 1, lug 10 is in contact with branch 13 of lever 12 and rotates the trigger 4 by through its branch 14 which is engaged with the trigger 4. The lug 4a of trigger 4 is released from the notch 5a of the hammer 5 which is then in a position army. The hammer 5 is then released to strike a primer, in a manner known per se.

Lorsqu'un déclenchement électrique du tir est souhaité, (figures 6 et 8), le tireur procède tout d'abord à l'effacement de la sûreté de détente et fait pivoter la détente 1 suivant une course C2 qui est inférieure à la course C1 nécessaire pour provoquer le déclenchement mécanique du tir. A l'issue de cette course C2, l'ergot 10 se trouve dans une position intermédiaire entre les branches 13 et 14 du levier 12, position dans laquelle il ne bloque plus le levier 12 qui peut donc pivoter (figure 8).When an electrical trigger of the shot is desired, (Figures 6 and 8), the shooter first proceeds to clearing the trigger safety and rotating the trigger 1 following a course C2 which is less than the stroke C1 necessary to cause tripping shooting mechanics. At the end of this C2 race, the pin 10 is located in an intermediate position between the branches 13 and 14 of lever 12, position in which it no longer blocks the lever 12 which can therefore pivot (Figure 8).

Pour valider le déclenchement électrique du tir, il faut donc que le tireur efface tout d'abord l'ergot 10 qui bloque la rotation de la gâchette 4. Cet effacement est obtenu lors de la course C2 de la détente 1.To validate the electric triggering of the shot, it is necessary so that the shooter erases first the lug 10 which blocks the rotation of the trigger 4. This erasure is obtained during of stroke C2 of trigger 1.

Une fois l'ergot 10 effacé, le signal S de commande automatique de tir peut être envoyé à l'actionneur 20, ce qui provoque le déplacement de la tige 22 qui prend appui sur la queue 24 du levier 12 pour provoquer la rotation de la gâchette 4 et libérer le marteau de percussion 5.Once the lug 10 has been deleted, the command signal S automatic firing can be sent to actuator 20, which causes the displacement of the rod 22 which bears on the tail 24 of lever 12 to cause rotation of the trigger 4 and release the percussion hammer 5.

Concrètement le mécanisme d'entraínement de la gâchette 4 comprend deux pièces distinctes non directement liées l'une à l'autre, à savoir la tringle 3 et le levier 12.Concretely the trigger drive mechanism 4 includes two separate rooms not directly related to each other the other, namely the rod 3 and the lever 12.

Lors d'un déclenchement mécanique du tir par actionnement de la détente 1 suivant une course C1, c'est l'ergot 10 de la tringle 3 qui vient au contact de la branche 13 du levier 12 pour faire pivoter ce dernier et par conséquent la gâchette 4. Par contre, lors d'un déclenchement électrique du tir, l'actionneur 20 agit directement sur le levier 12 pour faire pivoter la gâchette 4, à condition que le tireur ait validé ce déclenchement en faisant pivoter la détente 1 suivant la course C2, inférieure à la course C1 nécessaire à un déclenchement mécanique du tir, ce qui permet d'effacer uniquement l'ergot 10 qui bloquait en rotation la gâchette 4.During a mechanical triggering of the shot by actuation of the trigger 1 following a race C1, it is the lug 10 of the rod 3 which comes into contact with branch 13 of lever 12 to rotate the latter and therefore the trigger 4. On the other hand, when an electric fire is triggered, the actuator 20 acts directly on the lever 12 to make rotate trigger 4, provided the shooter has validated this trigger by rotating the trigger 1 according to the stroke C2, less than the stroke C1 required for a mechanical triggering of the shot, which makes it possible to erase only the lug 10 which blocked the trigger 4 in rotation.

On voit donc que grâce à l'ergot 10 porté par la tringle 3 une sûreté totale est assurée d'une façon simple et fiable et cela quelque soit le mode de tir choisi par le tireur. De plus le dispositif selon l'invention permet jusqu'au dernier moment un choix par le tireur du mode de tir souhaité.So we see that thanks to the lug 10 carried by the rod 3 total safety is ensured in a simple and reliable manner and that whatever the shooting mode chosen by the shooter. Of plus the device according to the invention allows until the last moment a choice by the shooter of the desired shooting mode.

Enfin la structure du dispositif de tir selon l'invention est mécaniquement très simple et peut encombrante. Ce dispositif peut donc être adapté pour s'intégrer dans tout type d'arme connue à déclenchement mécanique, permettant de donner à ces armes un niveau de sûreté supérieur et de les doter d'une capacité de tir à déclenchement électrique.Finally the structure of the firing device according to the invention is mechanically very simple and can be bulky. This device can therefore be adapted to integrate into any known type of weapon with mechanical release, allowing give these weapons a higher level of safety and have an electrically triggered firing capability.
