Description

La présente invention concerne une carabine à culasse linéaire.The present invention relates to a linear breech rifle.

Dans le domaine des armes à feu, FR-A-3 043 767 divulgue une carabine comprenant un canon, une culasse, qui est mobile en translation par rapport au canon et qui comprend une tête de culasse adaptée pour être engagée à l'intérieur d'une extrémité du canon et un mécanisme de verrouillage de la tête de culasse à l'intérieur du canon. Typiquement, le mécanisme de verrouillage comprend des segments basculants, qui sont disposés en cercle, accolés les uns aux autres, et qui sont mobiles chacun entre une position déverrouillée, où ils ne s'opposent pas au désengagement de la tête de culasse hors du canon, et une position verrouillée, où ils s'opposent au retrait de la tête de culasse hors du canon. On utilise un manchon, monté coulissant autour de la tête de culasse, pour faire basculer les segments basculants de leur position déverrouillée à leur position verrouillée, et réciproquement. Le déplacement du manchon est commandé par un levier, manoeuvrable par l'utilisateur. Ce type de carabine est qualifié de carabine à culasse linéaire (ou à réarmement linéaire), dans la mesure où il faut déplacer la culasse en translation pour recharger.In the field of firearms, FR-A-3,043,767 discloses a rifle comprising a barrel, a breech, which is movable in translation relative to the barrel and which comprises a bolt head adapted to be engaged inside an end of the barrel and a locking mechanism of the bolt head inside the barrel. Typically, the locking mechanism comprises tilting segments, which are arranged in a circle, contiguous to each other, and which are each movable between an unlocked position, where they do not oppose the disengagement of the bolt head out of the barrel , and a locked position, where they oppose the withdrawal of the bolt head out of the barrel. A sleeve, slidably mounted around the bolt head, is used to tilt the rocking segments from their unlocked position to their locked position, and vice versa. The movement of the sleeve is controlled by a lever, operable by the user. This type of rifle is qualified rifle linear breech (or linear reset), in that it must move the breech in translation to recharge.

De manière classique, une carabine comprend également un percuteur, dont la fonction est d'enfoncer l'amorce de la cartouche sous l'effet d'un effort élastique exercé par un ressort. La détente du ressort est commandée par une gâchette, dont le basculement s'effectue lorsque l'utilisateur appuie sur la queue de détente.Conventionally, a rifle also includes a striker, the function of which is to drive the primer of the cartridge under the effect of an elastic force exerted by a spring. The trigger of the spring is controlled by a trigger, which tilts when the user presses the trigger.

Avec une carabine à culasse linéaire, le séquencement lors d'un tir est le suivant. Tout d'abord, l'utilisateur recule la culasse à distance du canon pour pouvoir charger une munition (cartouche) à l'intérieur de la chambre. Ensuite, l'utilisateur bascule le levier vers lui pour armer le percuteur, c'est-à-dire comprimer le ressort du percuteur. Lors de cette étape, le corps du percuteur est entrainé par le levier vers l'arrière et vient s'accrocher à un cran formé sur la gâchette. La gâchette retient alors le percuteur en position et le ressort du percuteur est comprimé. Ensuite, l'utilisateur avance la culasse en direction du canon et amène la tête de culasse à l'intérieur du canon. L'utilisateur peut alors verrouiller le déplacement de la tête de culasse en pivotant le levier. Une fois que la tête de culasse est verrouillée, l'utilisateur peut tirer en agissant sur la gâchette par l'intermédiaire de la queue de détente.With a rifle with linear breech, the sequencing during a shot is as follows. First, the user moves the breech away from the barrel to be able to load a munition (cartridge) inside the chamber. Then, the user tilts the lever towards him to arm the striker, that is to say compress the spring of the firing pin. During this step, the body of the striker is driven by the lever backwards and clings to a notch formed on the trigger. The trigger then holds the firing pin in position and the firing pin spring is compressed. Then, the user advances the breech towards the barrel and brings the breech head inside the barrel. The user can then lock the displacement of the bolt head by pivoting the lever. Once the bolt head is locked, the user can pull by pulling the trigger through the trigger tail.

Pendant toute la phase de verrouillage de la tête de culasse, le percuteur est maintenu en position armée par la seule action de la gâchette. Ainsi, si l'utilisateur appuie sur la queue de détente avant que la tête de culasse soit complètement verrouillée, le percuteur est libéré et est poussé vers l'avant par la force du ressort. Il y a alors un risque que le percuteur enfonce l'amorce de la cartouche et le coup peut partir alors même que la tête de culasse n'est pas totalement verrouillée, ce qui est bien entendu inacceptable.During the entire locking phase of the bolt head, the striker is held in the armed position by the action of the trigger. Thus, if the user presses the trigger tail before the bolt head is fully locked, the striker is released and is pushed forward by the force of the spring. There is a risk that the striker drives the primer of the cartridge and the shot can leave even if the head of the breech is not completely locked, which is of course unacceptable.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un nouveau type de carabine, avec laquelle la gâchette est inactive tant que la tête de culasse n'est pas complètement verrouillée à l'intérieur du canon.It is these drawbacks that the invention intends to remedy more particularly by proposing a new type of rifle, with which the trigger is inactive until the bolt head is completely locked inside the barrel.

A cet effet l'invention concerne une carabine à culasse linéaire, comprenant un canon, la culasse, qui est mobile en translation par rapport au canon et qui comprend une tête de culasse adaptée pour être engagée à l'intérieur d'une extrémité du canon, la tête de culasse logeant intérieurement un percuteur chargé élastiquement par un ressort, une gâchette de maintien du percuteur, un mécanisme de verrouillage, pour verrouiller sélectivement la tête de culasse dans une configuration engagée à l'intérieur du canon, ce mécanisme comprenant un levier mobile entre une position déverrouillée et une position verrouillée. Conformément à l'invention, la course du levier entre la position déverrouillée et la position verrouillée comprend un premier tronçon, le long duquel le levier s'oppose au relâchement du percuteur sous la force du ressort et pousse le percuteur dans une configuration où la gâchette ne coopère plus avec le percuteur, et un deuxième tronçon, le long duquel le percuteur est rappelé dans une configuration où il est apte à coopérer avec la gâchette et où le levier, alors en position verrouillée, ne s'oppose plus au relâchement du percuteur.For this purpose the invention relates to a rifle with linear breech, comprising a barrel, the breech, which is movable in translation relative to the barrel and which comprises a bolt head adapted to be engaged inside a barrel end , the breech head internally housing a striker resiliently loaded by a spring, a trigger for holding the striker, a locking mechanism, for selectively locking the breech head in a configuration engaged within the barrel, this mechanism comprising a lever movable between an unlocked position and a locked position. According to the invention, the movement of the lever between the unlocked position and the locked position comprises a first section, along which the lever opposes the release of the firing pin under the force of the spring and pushes the firing pin into a configuration where the trigger no longer cooperates with the striker, and a second section, along which the striker is recalled in a configuration where it is able to cooperate with the trigger and where the lever, then in the locked position, no longer opposes the release of the striker .

Grâce à l'invention, pendant la phase de verrouillage de la tête de culasse, le percuteur est décliqueté de la gâchette et est maintenu en position armée par la seule action du levier. Tant que le levier n'a pas basculé en position verrouillée, il empêche donc le relâchement du percuteur. Ainsi, si l'utilisateur appuie sur la queue de détente avant que la tête de culasse soit complètement verrouillée, cela n'aura absolument aucun effet car, pendant cette phase, le percuteur est de toutes les manières désengagé de la gâchette. On évite ainsi le risque d'accident.Thanks to the invention, during the locking phase of the bolt head, the firing pin is released from the trigger and is held in the armed position by the action of the lever alone. As long as the lever has not switched to the locked position, it prevents the release of the firing pin. Thus, if the user presses the trigger before the bolt head is fully locked, this will have absolutely no effect because during this phase, the striker is in any way disengaged from the trigger. This avoids the risk of accidents.

Selon des aspects avantageux, mais non obligatoires de l'invention, une telle carabine peut comporter une ou plusieurs des caractéristiques suivantes, prises dans toute combinaison techniquement admissible :

  • Le levier comprend un organe mécanique, qui bute contre un organe mécanique complémentaire du percuteur lorsque le levier se trouve dans le premier tronçon, de façon à, d'une part, s'opposer au relâchement du percuteur sous la force du ressort et, d'autre part, à pousser le percuteur dans une configuration où la gâchette ne coopère plus avec le percuteur.
  • L'organe mécanique du levier et l'organe mécanique complémentaire du percuteur forment ensemble un mécanisme de came, permettant de transformer la rotation du levier en un mouvement de translation du percuteur.
  • Lorsque le levier est pivoté de la position verrouillée à la position déverrouillée, le levier est capable de pousser le percuteur, à l'encontre de l'effort élastique exercé par le ressort, jusque dans une position où le percuteur s'accroche à la gâchette par encliquetage.
  • La carabine comprend un autre ressort pour maintenir la gâchette dans une position où elle est apte à s'encliqueter avec le percuteur.
  • Le deuxième tronçon est consécutif au premier tronçon sur le trajet du levier entre la position déverrouillée et la position verrouillée.
  • Dans le premier tronçon, le percuteur est poussé dans une configuration où il est décliqueté de la gâchette.
  • L'axe de rotation du levier est perpendiculaire à l'axe de déplacement du percuteur.
  • Le mécanisme de verrouillage comprend des segments basculants disposés en cercle, de manière accolée les uns aux autres, les segments étant mobiles chacun entre une position déverrouillée, où ils ne s'opposent pas au désengagement de la tête de culasse hors du canon, et une position verrouillée, où ils s'opposent au retrait de la tête de culasse hors du canon. Le mécanisme de verrouillage comprend un organe pour faire basculer les segments basculants de leur position déverrouillée à leur position verrouillée, et réciproquement.
  • L'organe est un manchon monté coulissant autour de la tête de culasse.
According to advantageous, but not compulsory, aspects of the invention, such a rifle may include one or more of the following features, taken in any technically permissible combination:
  • The lever comprises a mechanical member, which abuts against a complementary mechanical member of the striker when the lever is in the first section, so as, on the one hand, to oppose the release of the striker under the force of the spring and, d on the other hand, to push the firing pin into a configuration where the trigger no longer cooperates with the firing pin.
  • The mechanical member of the lever and the complementary mechanical member of the firing pin together form a cam mechanism, making it possible to transform the rotation of the lever into a translation movement of the firing pin.
  • When the lever is pivoted from the locked position to the unlocked position, the lever is able to push the striker, against the elastic force exerted by the spring, into a position where the striker clings to the trigger by snapping.
  • The rifle includes another spring to hold the trigger in a position where it is able to snap with the striker.
  • The second section is consecutive to the first section on the path of the lever between the unlocked position and the locked position.
  • In the first section, the striker is pushed into a configuration where it is released from the trigger.

  • The locking mechanism comprises tilting segments arranged in a circle, contiguous to each other, the segments being movable each between an unlocked position, where they do not oppose the disengagement of the bolt head out of the barrel, and a locked position, where they oppose the withdrawal of the bolt head out of the barrel. The locking mechanism includes a member for tilting the tilting segments from their unlocked position to their locked position, and vice versa.
  • The member is a sleeve slidably mounted around the bolt head.

L'invention et d'autre avantages de celle-ci apparaitront plus clairement à la lumière de la description qui va suivre d'un mode de réalisation d'une carabine à culasse linéaire, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue de côté d'une culasse linéaire d'une carabine conforme à l'invention,
  • la figure 2 est une vue en perspective du percuteur de la carabine,
  • la figure 3 est une vue en perspective du levier de la carabine,
  • les figures 4 à 17 sont des coupes, représentant les étapes successives mises en oeuvre lors d'un tir.
The invention and other advantages thereof will appear more clearly in the light of the following description of an embodiment of a linear breech rifle, given by way of example only and with reference to drawings in which:
  • the figure 1 is a side view of a linear breech of a rifle according to the invention,
  • the figure 2 is a perspective view of the firing pin of the rifle,
  • the figure 3 is a perspective view of the lever of the rifle,
  • the Figures 4 to 17 are cuts, representing the successive stages implemented during a shot.

La figure 1 représente une culasse 2 de carabine. La culasse 2 est montée en translation sur une glissière 4 fixée sur le corps de la carabine, à proximité de la crosse. La culasse 2 est ainsi mobile en translation suivant un axe X2 sensiblement parallèle à un axe longitudinal de la carabine (non représentée). On parle donc ainsi d'une carabine à culasse linéaire, ou à réarmement linéaire.The figure 1 represents a breech 2 of rifle. The breech 2 is mounted in translation on a slide 4 fixed on the body of the rifle, near the butt. The yoke 2 is thus movable in translation along an axis X2 substantially parallel to a longitudinal axis of the rifle (not shown). We thus speak of a rifle linear breech, or linear rearming.

Classiquement, la carabine comprend un canon (non représenté), la culasse étant mobile en translation par rapport au canon. Comme décrit dans FR 3 043 767 , dont le contenu est incorporé par référence, la culasse 2 comprend une tête de culasse 6 adaptée pour être engagée à l'intérieur d'une extrémité du canon. La tête de culasse 6 loge intérieurement un percuteur 8, qui est représenté seul à la figure 2 et qui est chargé élastiquement par un ressort (non représenté), que l'on appelle couramment ressort de percuteur.Conventionally, the rifle comprises a barrel (not shown), the bolt being movable in translation relative to the barrel. As described in FR 3 043 767 , whose content is incorporated by reference, the yoke 2 comprises a bolt head 6 adapted to be engaged inside an end of the barrel. The breech head 6 internally houses a firing pin 8, which is shown alone at figure 2 and which is resiliently loaded by a spring (not shown), commonly known as a firing pin spring.

Le percuteur 8 est mobile en translation suivant un axe parallèle à l'axe X2 de déplacement de la culasse 2. Typiquement, lors d'un tir, le percuteur 8 est projeté vers l'avant sous la force du ressort de percuteur pour venir enfoncer l'amorce d'une cartouche (non représentée) logée dans une chambre du canon.The striker 8 is movable in translation along an axis parallel to the axis X2 of displacement of the cylinder head 2. Typically, during a firing, the firing pin 8 is projected forwardly under the force of the firing pin spring to come in the leader of a cartridge (not shown) housed in a barrel chamber.

Avantageusement, le percuteur 8 comprend des fentes latérales 82 de guidage en translation selon l'axe X2.Advantageously, the firing pin 8 comprises lateral slots 82 of translation guide along the axis X2.

Dans le présent document, la direction avant désigne une direction sensiblement parallèle à l'axe longitudinal de la carabine et orientée vers la direction du tir, et la direction arrière définit une direction complètement opposée, tournée vers le tireur.In this document, the forward direction means a direction substantially parallel to the longitudinal axis of the rifle and oriented towards the direction of fire, and the rear direction defines a completely opposite direction, facing the shooter.

Comme visible par exemple à la figure 6, la carabine comprend également une gâchette 12 de maintien du percuteur 8. La gâchette 12 est conçue pour maintenir le percuteur 8 en position armée, avec le ressort de percuteur comprimé, tant que le tireur n'a pas appuyé sur la queue de détente. Avantageusement, la carabine comprend un autre ressort 13, représenté schématiquement à la figure 7 uniquement, pour maintenir la gâchette 12 dans une position où elle est apte à s'encliqueter avec le percuteur 8. Notamment, la gâchette 12 comprend une extrémité 120 en forme de crochet, plus communément appelée cran de gâchette, qui est conçue pour venir se loger dans une encoche 84 du percuteur 8, afin de retenir le percuteur 8 en arrière.As visible for example in the figure 6 , the rifle also includes a trigger 12 for maintaining the firing pin 8. The trigger 12 is designed to maintain the striker 8 in the armed position, with the compressed striker spring, as long as the shooter did not press the trigger tail. Advantageously, the rifle comprises another spring 13, shown schematically in FIG. figure 7 only, to keep the trigger 12 in a position where it is adapted to engage with the striker 8. In particular, the trigger 12 comprises a hook-shaped end 120, more commonly known as a trigger, which is designed to come into contact with the striker 12. housed in a notch 84 of the striker 8, to hold the firing pin 8 back.

Avantageusement, la carabine comprend un mécanisme de verrouillage, pour verrouiller sélectivement la tête de culasse 6 dans une configuration engagée à l'intérieur du canon, ce mécanisme comprenant un levier 14, qui est représenté seul à la figure 3 et qui est mobile entre une position déverrouillée, représentée par exemple à la figure 7, et une position verrouillée, représentée par exemple à la figure 13.Advantageously, the rifle comprises a locking mechanism, for selectively locking the bolt head 6 in a configuration engaged inside the barrel, this mechanism comprising a lever 14, which is represented alone in the figure 3 and which is movable between an unlocked position, represented for example in the figure 7 , and a locked position, represented for example in the figure 13 .

Typiquement, l'axe de rotation du levier est perpendiculaire à l'axe de déplacement du percuteur 8 (et également à l'axe X2 de déplacement de la culasse 2).Typically, the axis of rotation of the lever is perpendicular to the axis of movement of the firing pin 8 (and also to the axis X2 of displacement of the yoke 2).

Dans l'exemple, et comme visible à la figure 9 notamment, le mécanisme de verrouillage comprend des segments basculants 16 disposés en cercle, de manière accolée les uns aux autres. Ces segments 16 sont logés dans une cavité définie dans le canon, à l'avant de la chambre de réception de la cartouche. Les segments 16 sont mobiles chacun entre une position déverrouillée, représentée par exemple à la figure 9, où ils ne s'opposent pas au désengagement de la tête de culasse 6 hors du canon, et une position verrouillée, représentée par exemple à la figure 13, où ils s'opposent au retrait de la tête de culasse 6 hors du canon. Tous les détails relatifs à la structure et au fonctionnement du mécanisme de verrouillage sont décrits dans la publication FR 3 043 767 .In the example, and as visible in the figure 9 in particular, the locking mechanism comprises tilting segments 16 arranged in a circle, contiguous to each other. These segments 16 are housed in a cavity defined in the barrel, at the front of the cartridge receiving chamber. The segments 16 are each movable between an unlocked position, represented for example at the figure 9 , where they do not oppose the disengagement of the bolt head 6 from the barrel, and a locked position, represented for example in the figure 13 , where they oppose the withdrawal of the bolt head 6 out of the barrel. All details concerning the structure and operation of the locking mechanism are described in the publication FR 3 043 767 .

Egalement, le mécanisme de verrouillage comprend un organe 18 pour faire basculer les segments basculants 16 de leur position déverrouillée à leur position verrouillée, et réciproquement.Also, the locking mechanism comprises a member 18 for tilting the rocking segments 16 from their unlocked position to their locked position, and vice versa.

De préférence, cet organe 18 est un manchon monté coulissant autour de la tête de culasse 6. Le déplacement du manchon 18 est commandé par l'action du levier 14. Notamment, lorsque le levier est en position déverrouillée, le manchon 18 est avancé et maintient les segments 16 dans leur configuration déverrouillée. A l'inverse, lorsque le levier est basculé en position verrouillée, le manchon 18 recule (voir les flèches F5 à la figure 13) et pousse les segments 16 dans leur configuration verrouillée, comme représenté par la flèche F6 à la figure 13.Preferably, this member 18 is a sleeve slidably mounted around the bolt head 6. The displacement of the sleeve 18 is controlled by the action of the lever 14. In particular, when the lever is in the unlocked position, the sleeve 18 is advanced and keeps the segments 16 in their unlocked configuration. Conversely, when the lever is tilted to the locked position, the sleeve 18 moves back (see the arrows F5 at the figure 13 ) and push the segments 16 into their locked configuration, as represented by the arrow F6 at the figure 13 .

On décrit ci-après une séquence de tir (étape par étape) en référence aux figures 4 à 13 notamment.A firing sequence (step by step) is described below with reference to Figures 4 to 13 especially.

Le tireur pivote le levier 14 vers l'arrière, c'est-à-dire dans le sens de la flèche F2 à la figure 4, pour armer le percuteur 8, c'est-à-dire pour comprimer le ressort de percuteur. Plus précisément, le tireur pivote le levier 14 de la position verrouillée, où il s'étend sensiblement de manière perpendiculaire à l'axe longitudinal de la carabine, vers la position déverrouillée, où il s'étend de manière inclinée par rapport à l'axe longitudinal de la carabine. Lors de cette étape, le corps du levier 14, qui porte la référence 140, pousse le percuteur 8 vers l'arrière. Le ressort de percuteur se retrouve alors comprimé. Le corps du levier 140 est logé à l'intérieur d'une enveloppe protectrice de la culasse 2.The shooter pivots the lever 14 backwards, that is to say in the direction of the arrow F2 at the figure 4 , to arm the striker 8, that is to say to compress the striker spring. More precisely, the shooter pivots the lever 14 from the locked position, where it extends substantially perpendicularly to the longitudinal axis of the rifle, to the unlocked position, where it extends inclined with respect to the longitudinal axis of the rifle. During this step, the body of the lever 14, which bears the reference 140, pushes the striker 8 rearwardly. The striker spring is then compressed. The body of the lever 140 is housed inside a protective envelope of the cylinder head 2.

Le percuteur 8 est guidé dans son mouvement selon l'axe X2 par des pions fixes 10, qui sont engagés respectivement dans les fentes 82 du percuteur 8.The striker 8 is guided in its movement along the axis X2 by fixed pins 10, which are respectively engaged in the slots 82 of the firing pin 8.

Lorsque le levier 14 arrive en bout de course, typiquement dans la configuration de la figure 7, le percuteur 8 vient s'accrocher, ou s'encliqueter, automatiquement sur la gâchette 12. En pratique, le percuteur 8 pousse légèrement la gâchette vers le bas, à l'encontre de l'effort élastique exercé par le ressort 13, pour passer le crochet saillant de la gâchette 12 et la gâchette revient automatiquement sous l'effort de rappel de son ressort dans une position où elle vient s'encliqueter avec le percuteur 8. Notamment, l'extrémité 120 de la gâchette 12 s'accroche au percuteur 8, plus précisément au niveau de l'encoche 84 du percuteur 8. Le percuteur 8 est alors maintenu en arrière, dans une position dite armée. On se trouve alors dans la configuration de la figure 7.When the lever 14 reaches the end of the stroke, typically in the configuration of the figure 7 , the striker 8 is hooked, or snap, automatically on the trigger 12. In practice, the striker 8 pushes the trigger slightly downwards, against the elastic force exerted by the spring 13, for pass the salient hook of the trigger 12 and the trigger automatically returns under the biasing force of its spring in a position where it comes into engagement with the striker 8. In particular, the end 120 of the trigger 12 clings to the firing pin 8, more precisely at the notch 84 of the striker 8. The striker 8 is then held back in a so-called armed position. We are then in the configuration of the figure 7 .

On dit alors que, lorsque le levier est pivoté de la position verrouillée à la position déverrouillée, le levier est capable de pousser le percuteur, à l'encontre de l'effort élastique exercé par le ressort de percuteur, jusque dans une position où le percuteur 8 s'accroche à la gâchette 12 par encliquetage.It is said that when the lever is pivoted from the locked position to the unlocked position, the lever is able to push the striker, against the elastic force exerted by the striker spring, to a position where the striker 8 clings to the trigger 12 by snapping.

Ensuite, le tireur recule la culasse 2 à distance du canon, comme représenté par la flèche F1 à la figure 1. Le tireur peut alors éventuellement insérer une cartouche à l'intérieur de la chambre du canon, c'est-à-dire chambrer une cartouche.Then, the shooter moves the bolt 2 away from the barrel, as represented by the arrow F1 at the figure 1 . The shooter can then optionally insert a cartridge inside the chamber of the barrel, that is to say chamber a cartridge.

Par la suite, le tireur déplace la culasse 2 vers l'avant, afin d'insérer la tête de culasse 6 à l'intérieur du canon. On se trouve alors dans la configuration de la figure 9. Le tireur doit alors verrouiller la tête de culasse 6 à l'intérieur du canon, pour éviter notamment le recul de la culasse lors du tir. Pour ce faire, le tireur bascule le levier 14 de la position déverrouillée vers la position verrouillée, c'est-à-dire dans le sens de la flèche F3 à la figure 11.Subsequently, the shooter moves the bolt 2 forward, to insert the bolt head 6 inside the barrel. We are then in the configuration of the figure 9 . The shooter must then lock the bolt head 6 inside the barrel, to avoid the recoil of the bolt during firing. To do this, the shooter toggles the lever 14 from the unlocked position to the locked position, that is to say in the direction of the arrow F3 to the figure 11 .

La course du levier 14 entre la position déverrouillée et la position verrouillée comprend un premier tronçon, défini entre la configuration de la figure 8 et la configuration de la figure 14, le long duquel le levier 14 s'oppose au relâchement du percuteur 8 sous la force du ressort de percuteur et pousse le percuteur 8 dans une configuration où la gâchette 12 ne coopère plus avec le percuteur 8.The stroke of the lever 14 between the unlocked position and the locked position comprises a first section, defined between the configuration of the figure 8 and the configuration of the figure 14 , along which the lever 14 opposes the release of the firing pin 8 under the force of the firing pin spring and pushes the striker 8 in a configuration where the trigger 12 no longer cooperates with the firing pin 8.

Plus précisément, le levier 14 comprend un organe mécanique 142, visible notamment à la figure 3, qui bute contre un organe mécanique complémentaire 80 du percuteur 8 lorsque le levier 14 se trouve dans le premier tronçon, de façon à, d'une part, s'opposer au relâchement du percuteur 8 sous la force du ressort de percuteur et, d'autre part, à pousser le percuteur 8 dans une configuration où la gâchette 12 ne coopère plus avec le percuteur 8. Dans l'exemple, le percuteur 8 est poussé dans une configuration où il est décliqueté de la gâchette 12. Ceci est visible lorsque l'on regarde l'agrandi de la figure 12, où l'on aperçoit la présence d'un jeu J entre les surfaces fonctionnelles de la gâchette 12 et celles du percuteur 8. Ce jeu J indique que la gâchette 12 ne coopère plus avec le percuteur 8. Ainsi, dans cette configuration, le tireur peut appuyer sur la queue de détente, sans que cela n'ait un quelconque effet. En d'autres termes, la gâchette 12 est complètement inactive.More specifically, the lever 14 comprises a mechanical member 142, visible in particular at the figure 3 , which abuts against a complementary mechanical member 80 of the striker 8 when the lever 14 is in the first section, so as, on the one hand, to oppose the release of the striker 8 under the force of the striker spring and, d on the other hand, to push the striker 8 in a configuration where the trigger 12 no longer cooperates with the firing pin 8. In the example, the firing pin 8 is pushed into a configuration where it is released from the trigger 12. This is visible when we look at the closeup of the figure 12 , where we see the presence of a clearance J between the functional surfaces of the trigger 12 and those of the striker 8. This clearance J indicates that the trigger 12 no longer cooperates with the striker 8. Thus, in this configuration, the shooter can press the tail of relaxation, without this having any effect. In other words, the trigger 12 is completely inactive.

Comme visible à la figure 10, l'organe mécanique 142 du levier, qui est formé dans l'exemple par un relief saillant, bute contre l'organe mécanique complémentaire 80 du percuteur 8, ce qui permet de retenir le percuteur 8 vers l'arrière et d'éviter que le coup parte tout seul. Typiquement, l'organe 80 mentionné ci-dessus est formé par un relief saillant, formé sur un côté du percuteur 8 (voir figure 2).As visible at figure 10 , the mechanical member 142 of the lever, which is formed in the example by a protruding relief, abuts against the complementary mechanical member 80 of the firing pin 8, which makes it possible to retain the striker 8 towards the rear and to prevent that the shot leaves all alone. Typically, the member 80 mentioned above is formed by a protruding relief, formed on one side of the striker 8 (see figure 2 ).

Avantageusement, l'organe mécanique 142 du levier et l'organe mécanique complémentaire 80 du percuteur forment ensemble un mécanisme de came, permettant de transformer la rotation F3 du levier 14 en un mouvement de translation F4 du percuteur 8. Cela signifie que les surfaces fonctionnelles des organes 142 et 80, c'est-à-dire les surfaces de contact, sont complémentaires l'une de l'autre. En particulier, ces surfaces fonctionnelles sont inclinées de manière à obtenir un effet de coin, qui transforme le mouvement de rotation du levier 14 en un mouvement de translation.Advantageously, the mechanical member 142 of the lever and the complementary mechanical member 80 of the striker together form a cam mechanism, making it possible to transform the rotation F3 of the lever 14 into a translation movement F4 of the striker 8. This means that the functional surfaces bodies 142 and 80, that is to say the contact surfaces, are complementary to one another. In particular, these functional surfaces are inclined so as to obtain a wedge effect, which transforms the rotational movement of the lever 14 into a translation movement.

La course du levier 14 entre la position déverrouillée et la position verrouillée comprend par ailleurs un deuxième tronçon, défini entre la configuration de la figure 14 et la configuration de la figure 16, et, le long duquel le percuteur 8 est rappelé élastiquement vers l'avant, par la force du ressort de percuteur, dans une configuration où il est apte à coopérer avec la gâchette 12 et où le levier 14, alors en position verrouillée, ne s'oppose plus au relâchement du percuteur 8.The stroke of the lever 14 between the unlocked position and the locked position also comprises a second section, defined between the configuration of the figure 14 and the configuration of the figure 16 , and along which the striker 8 is resiliently biased forward, by the force of the striker spring, in a configuration where it is adapted to cooperate with the trigger 12 and where the lever 14, then in the locked position, does not is opposed more to the release of the firing pin 8.

Dans l'exemple, le deuxième tronçon est consécutif au premier tronçon sur le trajet du levier entre la position déverrouillée et la position verrouillée.In the example, the second section is consecutive to the first section in the path of the lever between the unlocked position and the locked position.

Dans la majorité des cas, le percuteur 8 est rappelé dans une configuration où il coopère avec la gâchette 12, c'est-à-dire dans une configuration où la gâchette 12 maintient le percuteur en position armée par encliquetage.In most cases, the striker 8 is recalled in a configuration where it cooperates with the trigger 12, that is to say in a configuration where the trigger 12 holds the striker in the armed position by snapping.

La carabine est alors dans la configuration de la figure 16. Dans cette configuration, la tête de culasse 6 est verrouillée à l'intérieur du canon, et le percuteur 8 est maintenu par la gâchette 12. En appuyant sur la queue de détente (non représentée), le tireur fait basculer la gâchette 12 dans le sens de la flèche F7, ce qui libère le percuteur 8, lequel est alors projeté vers l'avant sous la force du ressort de percuteur. Le percuteur 8 vient alors enfoncer l'amorce de la cartouche montée à l'intérieur du canon, et le coup part.The rifle is then in the configuration of the figure 16 . In this configuration, the bolt head 6 is locked inside the barrel, and the striker 8 is held by the trigger 12. By pressing the trigger (not shown), the shooter toggles the trigger 12 in the direction of the arrow F7, which releases the firing pin 8, which is then projected forward under the force of the firing pin spring. The striker 8 then comes to drive the primer of the cartridge mounted inside the barrel, and the shot goes.

En variante non représentée, les organes mécaniques 142 et 80 peuvent être prévus sous d'autres formes (crans, bosses, entaille, rainures, etc.).Alternatively not shown, the mechanical members 142 and 80 may be provided in other forms (notches, bumps, notches, grooves, etc.).

Les caractéristiques du mode de réalisation représenté sur les figures et des variantes non représentées envisagées ci-dessus peuvent être combinées entre elles pour générer de nouveaux modes de réalisation de l'invention.The features of the embodiment shown in the figures and variants not shown envisaged above can be combined with each other to generate new embodiments of the invention.
