Description

PISTOLET SEMI-AUTOMATIQUE A CANON COULISSANT  SEMI-AUTOMATIC SLIDING GUN PISTOL
La présente invention concerne un pistolet semi-automatique à canon coulissant. The present invention relates to a semi-automatic pistol with sliding barrel.
Un pistolet est défini comme étant semi-automatique du fait qu'il est pourvu d'un chargeur à partir duquel une nouvelle cartouche est automatiquement chargée après chaque tir, alors qu'il demande une nouvelle pression sur la détente pour la mise à feu de chaque cartouche jusqu'à l'épuisement du chargeur.  A pistol is defined as being semi-automatic because it is provided with a magazine from which a new cartridge is automatically loaded after each shot, while it requests a new pressure on the trigger for the firing of each cartridge until the charger runs out.
Un pistolet semi-automatique classique comporte une carcasse dans laquelle est déposé un canon. L'extrémité arrière du canon forme une chambre de tir ou de combustion associée à une cavité de réception d'une cartouche présentant une ouverture dirigée vers le bas pour recevoir un chargeur, et une ouverture latérale associée à un mécanisme d'extraction et d'éjection de la douille de la cartouche après le tir.  A conventional semi-automatic pistol has a carcass in which is deposited a gun. The rear end of the barrel forms a firing or combustion chamber associated with a cartridge receiving cavity having a downwardly directed opening for receiving a magazine, and a side opening associated with a firing mechanism. ejection of the cartridge sleeve after firing.
La partie supérieure de la carcasse d'un pistolet classique est couverte par une culasse montée coulissante en s'étendant sur le canon qui est relié à la carcasse. La culasse comporte un percuteur associé à un marteau ou chien monté basculant à l'arrière du pistolet. Le percuteur présente la forme d'une aiguille montée axialement déplaçable dans la culasse pour transmettre la percussion du chien à une cartouche logée dans la chambre de tir à l'extrémité arrière du canon.  The upper part of the carcass of a conventional pistol is covered by a breech slidably mounted extending on the barrel which is connected to the carcass. The breech includes a striker associated with a hammer or dog mounted tilting at the rear of the gun. The striker has the shape of a needle mounted axially movable in the cylinder head to transmit the dog's percussion to a cartridge housed in the firing chamber at the rear end of the barrel.
Lors du tir, la culasse est projetée en arrière par les gaz de combustion créant une pression importante dans le canon. Un ressort récupérateur comprimé lors du recul de la culasse ramène ensuite celle-ci dans sa position de départ suite à l'extraction et l'éjection de la douille, ce qui permet de faire monter une nouvelle cartouche dans la cavité de réception pour ensuite être déplacée axialement en passant sur une rampe pour venir se loger dans la chambre du canon. When fired, the cylinder head is thrown back by the combustion gases creating a significant pressure in the barrel. A collector spring compressed during the recoil of the cylinder head then returns it to its starting position following the extraction and ejection of the sleeve, which allows to mount a new cartridge in the cavity of reception to then be moved axially by passing on a ramp to come to lodge in the chamber of the gun.
Par rapport aux pistolets classiques, un des avantages d'un pistolet semi-automatique à canon coulissant réside dans le fait qu'il permet, pour une longueur hors tout donnée, de loger un canon d'une longueur sensiblement augmentée par rapport à celle du canon d'un pistolet classique. Un canon plus long apporte une précision améliorée. Un pistolet de ce genre peut ainsi être plus compact pour la même longueur du canon. Compared to conventional pistols, one of the advantages of a semi-automatic sliding gun is that it allows, for a given overall length, to accommodate a barrel of a length substantially increased compared to that of the gun of a classic gun. A longer barrel provides improved accuracy. A pistol of this kind can thus be more compact for the same length of the barrel.
Un pistolet semi-automatique à canon coulissant est connu de la publication US 1376456. Cependant, le pistolet y décrit comporte un grand nombre de pièces compliqués à fabriquer et à mettre en œuvre. Le guidage du canon sur la carcasse n'est pas non plus optimale puisqu'il est effectué d'un seul côté du canon.  A semi-automatic sliding gun is known from US 1376456. However, the gun described therein has a large number of complicated parts to manufacture and implement. Guiding the barrel on the carcass is also not optimal since it is performed on one side of the barrel.
Un but de l'invention est de simplifier la construction du pistolet par la réduction du nombre de pièces nécessaires au bon fonctionnement du pistolet, ce qui entraîne également un coût de fabrication sensiblement réduit.

Dans la coupe longitudinale du pistolet de la figure 1 , les éléments essentiels sont montrés dans leur position de repos dans la carcasse 1, avant utilisation du pistolet.  In the longitudinal section of the gun of Figure 1, the essential elements are shown in their rest position in the carcass 1, before use of the gun.
La carcasse 1 est composée d'une crosse 2 inclinée en arrière et d'une partie supérieure 3 d'extension horizontale dans laquelle est déposé un canon 4. L'extrémité arrière du canon 4 constitue une chambre de tir ou de combustion 5 qui est associée à une cavité de réception 6 d'une cartouche 7 (non représentée sur la figure 1). La cavité 6 est pourvue d'une ouverture 8 dirigée vers le bas pour communiquer avec un chargeur 9 (illustré aux figures 8 à 13) et d'une ouverture latérale d'éjection 8' (voir figure 13) associée à un mécanisme pour l'extraction et l'éjection de la douille 7" après le tir. Ce mécanisme sera expliqué en détail plus loin.  The carcass 1 is composed of a butt 2 inclined behind and an upper part 3 of horizontal extension in which is deposited a barrel 4. The rear end of the barrel 4 is a firing chamber or combustion 5 which is associated with a receiving cavity 6 of a cartridge 7 (not shown in Figure 1). The cavity 6 is provided with an opening 8 directed downwards to communicate with a loader 9 (illustrated in FIGS. 8 to 13) and an ejection lateral opening 8 '(see FIG. 13) associated with a mechanism for the Extraction and ejection of the 7 "bushing after firing This mechanism will be explained in detail later.
Le pistolet comprend également un mécanisme de mise à feu comprenant une détente 10 reliée à des moyens d'armement et de retenue d'un chien 11 monté basculant sur un axe 11 ' à l'arrière du pistolet. Un ressort 12 est disposé de manière à appuyer sur l'extrémité basse du chien 11 pour le solliciter vers la position montrée à la figure 1. The gun also includes a firing mechanism comprising a trigger 10 connected to means for cocking and retaining a dog 11 pivotally mounted on an axis 11 'at the rear of the gun. A spring 12 is arranged to press the lower end of the dog 11 to urge it towards the position shown in FIG.
Pour viser avant le tir, le pistolet est de manière classique également pourvu d'un cran de mire 13 placé en arrière et d'un guidon 14 placé en avant sur la face supérieure du pistolet.  To aim before firing, the pistol is conventionally also provided with a rear sight 13 placed behind and a handlebar 14 placed forward on the upper face of the pistol.
La détente 10 est solidaire d'un bras d'actionnement 15. L'ensemble détente-bras d'actionnement est monté basculant autour d'un axe 16 qui s'étend dans un trou oblong 17 dans l'ensemble. Le bras d'actionnement 15 est sollicité vers le bas par un ressort en épingle 18 disposé au-dessus du bras d'actionnement 15 dont l'une des extrémités est en appui contre la face supérieure du bras d'actionnement et l'autre extrémité est en appui contre la carcasse 1.  The trigger 10 is integral with an actuating arm 15. The trigger arm-actuator assembly is pivotally mounted about an axis 16 which extends into an oblong hole 17 in the assembly. The actuating arm 15 is biased downwards by a pin spring 18 disposed above the actuating arm 15, one end of which bears against the upper face of the actuating arm and the other end. is in support against the carcass 1.
Le bras d'actionnement 15 agit sur un organe d'armement et de retenue du chien en position armée, généralement appelé gâchette. Cet organe est dans l'exemple illustré constitué d'une biellette 19 qui à son extrémité arrière est directement reliée au chien 11 par une articulation 20. La biellette est pourvue d'une fente de guidage en L 21 dont la grande branche 2Γ s'étend horizontalement et la petite branche 21 " s'étend verticalement vers le haut (voir figure 4). Un pion de guidage 22 porté par la carcasse 1 s'étend dans la fente de guidage en L 21 de manière à permettre à la biellette 19 d'effectuer un mouvement de translation en arrière afin d'armer le chien 11.  The actuating arm 15 acts on an arming and retaining member of the dog in the armed position, generally called a trigger. This member is in the illustrated example consisting of a rod 19 which at its rear end is directly connected to the dog 11 by a hinge 20. The rod is provided with an L-shaped guide slot 21 whose large branch 2Γ s' extends horizontally and the small branch 21 "extends vertically upwards (see Figure 4) .A guide pin 22 carried by the carcass 1 extends in the L-shaped guide slot 21 so as to allow the link 19 to translate back to arm the dog 11.
A la fin de ce mouvement de translation en arrière, la biellette 19 peut être légèrement déplacée vers le bas sous l'effet de l'action d'un ressort de pression 23 de sorte que le pion de guidage 22 soit logé dans la petite branche 21 " de la fente de guidage 21 de manière à retenir la biellette 19 pour bloquer le chien 11 dans sa position armée. At the end of this translational movement backwards, the link 19 may be slightly moved downwards under the effect of the action of a pressure spring 23 so that the guiding pin 22 is housed in the small branch 21 "of the guide slot 21 so as to retain the link 19 to block the dog 11 in its armed position.
L'une des extrémités du ressort de pression 23 est en appui contre la surface supérieure de la partie arrière de la biellette 19 pour la solliciter vers le bas afin de maintenir le pion 22 dans la petite branche dans sa position haute de blocage (voir figure 1). One of the ends of the pressure spring 23 bears against the upper surface of the rear part of the rod 19 to urge it downwards in order to keep the pin 22 in the small branch in its high locking position (see FIG. 1).
Pour repousser la biellette vers le haut de manière à faire entrer le pion 22 dans la branche longue de la fente de guidage en L 21, le bras d'actionnement 15 est à son extrémité arrière pourvu d'un bec formant une came 24 destinée à venir appuyer sur un ergot 25 prévu sur un bord inférieur de la biellette 19 lorsque l'extrémité arrière du bras d'actionnement 15 est basculée vers le haut suite à une pression sur la détente 10. La biellette 19 est ainsi libérée de sa position de retenue du chien 11 et se déplace vers l'avant afin de permettre au chien de basculer pour déclencher le tir.  To push the link upwards so as to bring the pin 22 into the long branch of the L-shaped guide slot 21, the actuating arm 15 is at its rear end provided with a spout forming a cam 24 for press a lug 25 provided on a lower edge of the rod 19 when the rear end of the actuating arm 15 is tilted upwards by pressure on the trigger 10. The rod 19 is thus released from its position of dog restraint 11 and moves forward to allow the dog to rock to trigger the shot.
Le bras d'actionnement 15 est en outre à proximité de la came 24 pourvu d'une rainure 26 dans laquelle est logé un organe élastique sous forme d'un ressort à fil 27 venant lors du basculement du bras d'actionnement 15 en butée contre un ergot 28 disposé en haut sur la biellette 19, au-dessus de la fente en L 21. Ce ressort 27 forme ainsi avec l'ergot 28 un arrêt souple. The actuating arm 15 is also close to the cam 24 provided with a groove 26 in which is housed a resilient member in the form of a wire spring 27 coming from the tilting of the actuating arm 15 abutting against a lug 28 disposed at the top of the link 19, above the L-shaped slot 21. This spring 27 thus forms with the lug 28 a flexible stop.
Le canon 4 est monté axialement coulissant pour être déplacé entre une position avancée vers laquelle il est entraîné par la friction de la balle 7' au moment du tir d'une cartouche 7, et une position reculée vers laquelle il est repoussé par un ressort récupérateur 29 qui est comprimé par le canon 4 lors de son déplacement vers la position avancée. Le canon 4 recule jusqu'à venir chambrer une nouvelle cartouche 7 qui est préalablement montée du chargeur dans la cavité de réception 6 lors du déplacement du canon 4 vers sa position avancée. The barrel 4 is axially slidably mounted to be moved between an advanced position towards which it is driven by the friction of the bullet 7 'when firing a cartridge 7, and a retracted position towards which it is pushed by a recuperating spring 29 which is compressed by the barrel 4 when moving to the advanced position. The barrel 4 moves back until it comes to chamber a new cartridge 7 which is previously mounted charger in the receiving cavity 6 when moving the barrel 4 to its advanced position.
Lors de son déplacement vers la position reculée, le canon 4 est en effet repoussé jusqu'à venir en appui contre une paroi arrière 30 de la cavité de réception 6 et la nouvelle cartouche 7 est ainsi automatiquement placée dans la chambre de tir 5 du canon 4, sans qu'il soit nécessaire de la déplacer longitudinalement, comme cela est le cas dans les pistolets classiques. Plus précisément, la cartouche 7 monte toujours parallèlement à l'axe A-A du canon 4 et elle est également stockée parallèlement à cet axe dans le chargeur.  When it moves to the retracted position, the barrel 4 is pushed back to bear against a rear wall 30 of the receiving cavity 6 and the new cartridge 7 is thus automatically placed in the firing chamber 5 of the barrel 4, without the need to move longitudinally, as is the case in conventional guns. More specifically, the cartridge 7 always rises parallel to the axis A-A of the barrel 4 and is also stored parallel to this axis in the magazine.
Dans un pistolet classique à canon fixe, les cartouches sont au contraire stockées inclinées dans le chargeur afin de faciliter leur passage sur une rampe pour être déplacées longitudinalement vers la chambre de tir. Un des avantages du pistolet à canon coulissant est que le déplacement longitudinal de la cartouche vers la chambre de tir est supprimé, et par conséquent, aucune rampe n'est nécessaire, ce qui exclue le risque d'un coincement de la cartouche pendant un tel déplacement dans le sens longitudinal. In a conventional pistol fixed barrel, the cartridges are instead stored inclined in the charger to facilitate their passage on a ramp to be moved longitudinally to the firing chamber. One of the advantages of the sliding gun is that the longitudinal movement of the cartridge towards the firing chamber is eliminated, and therefore, no ramp is necessary, which precludes the risk of jamming the cartridge during such a period. displacement in the longitudinal direction.
Le canon 4 peut reculer jusqu'à la paroi arrière de la cavité de réception 6 de la cartouche 7, et par conséquent, il est possible de déposer dans la carcasse 1 un canon 4 qui présente une longueur sensiblement augmentée par rapport à la longueur d'un canon dans un pistolet classique à canon fixe présentant la même longueur hors tout. Cette longueur augmentée ressort clairement d'une comparaison des figures 1 et 5, cette dernière montrant le canon 4 dans sa position avancée.  The barrel 4 can move back to the rear wall of the receiving cavity 6 of the cartridge 7, and consequently it is possible to deposit in the carcass 1 a barrel 4 which has a length substantially increased with respect to the length of the barrel 4. a gun in a conventional fixed barrel pistol having the same overall length. This increased length is clear from a comparison of Figures 1 and 5, the latter showing the barrel 4 in its advanced position.
A titre d'exemple, pour une longueur hors tout du pistolet de 183 mm, un pistolet classique à canon fixe présente une longueur de canon d'environ 97 mm, alors que le pistolet selon l'invention présentera une longueur de canon d'environ 155 mm. Comme déjà mentionné, une longueur augmentée du canon donne une meilleure précision au tir. As an example, for an overall length of the 183 mm gun, a conventional fixed barrel gun has a barrel length about 97 mm, while the gun according to the invention will have a barrel length of about 155 mm. As already mentioned, an increased length of the barrel gives a better accuracy to the shot.
La paroi arrière 30 de la cavité de réception 6 de la cartouche 7 est pourvue d'un orifice 31 centré sur la chambre de tir 5 du canon 4. Cet orifice 31 permet au chien 11 de venir percuter directement par cet orifice The rear wall 30 of the receiving cavity 6 of the cartridge 7 is provided with an orifice 31 centered on the firing chamber 5 of the barrel 4. This orifice 31 allows the dog 11 to strike directly through this orifice
31 une cartouche qui se trouve dans la chambre de tir 5 et qui alors prend appui contre cette paroi arrière 30. 31 a cartridge which is in the firing chamber 5 and which then bears against this rear wall 30.
Cet agencement qui est une conséquence logique du fait que la chambre de tir 5 se trouve au moment du tir en appui contre la paroi arrière 30 de la cavité de réception 6 de la cartouche 7, fait que le percuteur nécessaire aux pistolets classiques est supprimé. A cet égard, le pistolet selon l'invention fonctionne comme un revolver dans lequel le chien vient directement percuter la cartouche.  This arrangement is a logical consequence of the fact that the firing chamber 5 is at the time of the firing bearing against the rear wall 30 of the receiving cavity 6 of the cartridge 7, so that the striker required for conventional guns is removed. In this respect, the gun according to the invention functions as a revolver in which the dog directly hits the cartridge.
Afin d'optimiser la précision de percussion, l'extrémité de percussion du chien 11 présente une forme globalement conique complémentaire de la forme intérieure de l'orifice 31 dans la paroi arrière 30.  In order to optimize the percussion accuracy, the percussion end of the dog 11 has a generally conical shape complementary to the inner shape of the orifice 31 in the rear wall 30.
Selon l'invention, le canon 4 coulisse dans un évidement cylindrique According to the invention, the barrel 4 slides in a cylindrical recess
32 formé dans la carcasse 1. Dans son mouvement alternatif entre la position avancée et la position reculée, le canon 4 est guidé par un collet 33 prévu sur la périphérie du canon et par un embout 34 à trou central de guidage disposé à l'extrémité avant du pistolet. 32 formed in the carcass 1. In its reciprocating movement between the advanced position and the retracted position, the barrel 4 is guided by a collar 33 provided on the periphery of the barrel and by a tip 34 with central guide hole disposed at the end. before the gun.
Le ressort récupérateur 29 est un ressort hélicoïdal disposé dans un interstice annulaire 35 formé entre l'évidement cylindrique 32 et le canon. Ce ressort hélicoïdal prend appui d'un côté sur le collet 33 du canon 4 et de l'autre côté sur l'embout 34. Afin de définir le recul du canon 4 vers sa position reculée, un ergot 36 est avantageusement prévu sur la face intérieure de l'évidement cylindrique 32 pour former une butée au collet 33 du canon 4 lorsqu'il revient dans sa position reculée. The recuperating spring 29 is a helical spring disposed in an annular gap 35 formed between the cylindrical recess 32 and the barrel. This coil spring is supported on one side on the collar 33 of the barrel 4 and on the other side on the tip 34. In order to define the recoil of the barrel 4 towards its retracted position, a lug 36 is advantageously provided on the inner face of the cylindrical recess 32 to form a stop at the collar 33 of the barrel 4 when it returns to its retracted position.
Afin de verrouiller le canon 4 dans sa position de non utilisation montrée à la figure 1, une sécurité sous forme d'un dispositif de verrouillage 37 du canon est prévu à l'extrémité avant du pistolet. Ce dispositif comporte une plaque 38 fixée à l'extrémité avant du pistolet et comportant un trou central associé à un filet pour coopérer avec un écrou 39. Le dispositif de sécurité 37 peut en variante comporter un dispositif de verrouillage à baïonnette.  In order to lock the barrel 4 in its non-use position shown in Figure 1, a security in the form of a barrel locking device 37 is provided at the front end of the gun. This device comprises a plate 38 attached to the front end of the gun and having a central hole associated with a thread to cooperate with a nut 39. The safety device 37 may alternatively comprise a bayonet locking device.
Pour son réarmement automatique, le pistolet selon l'invention comporte un levier pivotant 40 agissant sur la biellette 19 formant organe d'armement et de retenue du chien en position armée.  For its automatic reset, the gun according to the invention comprises a pivoting lever 40 acting on the rod 19 forming arming and retaining member of the dog in the armed position.
Le levier 40 est monté pivotant sur un axe de rotation 41. Le levier 40 présente une extrémité haute 40' actionnée par le canon 4 lors du déplacement de celui-ci vers sa position avancée, et une extrémité basse 40" présentant une forme arrondie formant came disposée en regard de l'extrémité avant de la biellette 19. Le levier 40 est à son extrémité haute 40' pourvue d'un ergot 42 qui lors de l'avancement du canon 4 est entraîné par un ergot 43 disposé à l'extrémité arrière du canon. Cela provoque le basculement du levier pivotant 40 (voir figure 5) de sorte que son extrémité basse 40" vient repousser en arrière la biellette 19 qui à son tour fait basculer le chien 11 dans sa position armée en même temps que la biellette est verrouillée dans cette position de la manière déjà décrite.  The lever 40 is pivotally mounted on an axis of rotation 41. The lever 40 has a high end 40 'actuated by the barrel 4 during the movement thereof to its advanced position, and a low end 40 "having a rounded shape forming cam disposed opposite the front end of the rod 19. The lever 40 is at its upper end 40 'provided with a lug 42 which during the advancement of the barrel 4 is driven by a lug 43 disposed at the end This causes the pivoting lever 40 to tilt (see FIG. 5) so that its lower end 40 "pushes back the link 19 which in turn tilts the dog 11 into its armed position at the same time as the rod is locked in this position as already described.
Le levier 40, ainsi que la biellette 19 et le bras d'actionnement 15 peuvent avantageusement être fabriqués avec une grande précision en étant découpés au laser à partir d'une tôle métallique. The lever 40, as well as the rod 19 and the actuating arm 15 can advantageously be manufactured with great precision by being laser cut from a metal sheet.
Le pistolet est en outre pourvu d'un mécanisme d'extraction et d'éjection de la douille 7" suite au tir de la cartouche 7. Ce mécanisme comprend une lame d'éjection 44 disposée en regard de l'ouverture d'éjection 8' et dont l'une des extrémités est reliée au canon 4 et l'autre extrémité présente une boucle élastique 45 s'étendant radialement (voir figures 2a et 2b). Cette boucle 45 est comprimée par la cartouche 7 lors de la montée de celle-ci dans la cavité de réception 6 de la cartouche. The gun is further provided with a mechanism for extracting and ejecting the socket 7 "following the firing of the cartridge 7. This mechanism comprises an ejection blade 44 disposed facing the ejection opening 8 and one end of which is connected to the barrel 4 and the other end has a radially extending elastic loop 45 (see Figures 2a and 2b) This loop 45 is compressed by the cartridge 7 during the rise of the in the receiving cavity 6 of the cartridge.
Afin de bien centrer la cartouche 7 lors de sa montée dans la cavité de réception 6, la paroi arrière 30 de celle-ci est pourvue d'un premier ergot In order to properly center the cartridge 7 when mounted in the receiving cavity 6, the rear wall 30 thereof is provided with a first lug
46 disposé de manière à former une butée supérieure, et un deuxième ergot46 arranged to form a top stop, and a second lug
47 disposé de manière à former une butée latérale. 47 arranged to form a lateral stop.
L'ergot est pourvu d'une saillie latérale apte à se poser derrière un bourrelet prévu sur le culot de la douille de manière à retenir celle-ci en place pour l'extraire de la chambre 5 lorsque le canon est déplacé vers sa position avancée. The lug is provided with a lateral projection adapted to be placed behind a bead provided on the base of the sleeve so as to retain it in place to extract it from the chamber 5 when the barrel is moved to its advanced position. .
Les ergots 46 et 47 ainsi que la boucle 45 de la lame d'éjection 44 sont reçus dans des découpes formées dans la face d'extrémité arrière du canon 4 de manière à permettre à celui-ci de revenir en arrière jusqu'à ce qu'il se trouve en appui contre la paroi arrière 30 de la cavité de réception 5.  The lugs 46 and 47 as well as the loop 45 of the ejection blade 44 are received in cutouts formed in the rear end face of the barrel 4 so as to allow it to go back until it bears against the rear wall 30 of the receiving cavity 5.
La lame d'éjection 44 présente dans l'exemple illustré deux fentes 48 de guidage longitudinal recevant un pion 49 faisant saillie à partir de la paroi interne de la cavité de réception 6 de manière à limiter le déplacement axial de la lame d'éjection 44 dans une position d'extraction. The ejection blade 44 has in the illustrated example two slots 48 of longitudinal guide receiving a pin 49 projecting from the inner wall of the receiving cavity 6 so as to limit the axial displacement of the ejection blade 44 in an extraction position.
Le fonctionnement du pistolet selon l'invention sera maintenant décrit en référence aux figures 1, 5 à 7. The operation of the gun according to the invention will now be described with reference to FIGS. 1, 5 to 7.
La figure 1 montre les éléments essentiels du pistolet selon l'invention dans une position de repos ou de non utilisation. Dans cette position, le canon 4 est entièrement reculé dans la carcasse 1 et couvre l'ouverture 8 vers la cavité de réception 6 des cartouches.  Figure 1 shows the essential elements of the gun according to the invention in a rest position or non-use. In this position, the barrel 4 is fully retracted into the carcass 1 and covers the opening 8 to the receiving cavity 6 of the cartridges.
La figure 5 illustre le premier armement qui se fait manuellement après avoir mis un chargeur 9 en place dans son logement dans la crosse 2 du pistolet pour le faire communiquer avec la cavité de réception 6 des cartouches 7 par l'intermédiaire de l'ouverture 8. Le chargeur est ici schématiquement montré par une rangée de cartouches 7 disposées parallèlement à l'axe A- A du canon 4.  FIG. 5 illustrates the first arming which is done manually after putting a magazine 9 in place in its housing in the butt 2 of the gun to make it communicate with the receiving cavity 6 of the cartridges 7 via the opening 8 The charger is here schematically shown by a row of cartridges 7 arranged parallel to the axis A-A of the barrel 4.
Après avoir déverrouillé le dispositif de verrouillage 37, on tire le canon 4 vers l'avant à l'encontre de l'action du ressort récupérateur 29 pour dégager l'ouverture 8 afin de permettre à une cartouche de monter dans la cavité de réception 6 tout en étant centré à l'aide des deux ergots 46, 47 et de la boucle 45 de la lame d'éjection 44. La saillie de l'ergot latéral 47 est alors placée derrière le bourrelet de la douille.  After unlocking the locking device 37, the barrel 4 is pulled forward against the action of the recuperator spring 29 to disengage the opening 8 to allow a cartridge to mount into the receiving cavity 6 while being centered with the two lugs 46, 47 and the loop 45 of the ejector blade 44. The projection of the lateral lug 47 is then placed behind the bead of the sleeve.
En même temps, l'ergot 43 à l'extrémité arrière du canon 4 entraînera l'ergot 42 du levier pivotant 40 qui basculera en repoussant la biellette 19 qui alors va faire basculer le chien 11 dans sa position armée et verrouillée par l'entrée du pion de guidage 22 dans la branche verticale de la fente en L 21 de la biellette 19.  At the same time, the lug 43 at the rear end of the barrel 4 will cause the lug 42 of the pivoting lever 40 which will swing by pushing the rod 19 which then will tilt the dog 11 in its armed position and locked by the entrance guide pin 22 in the vertical branch of the L-shaped slot 21 of the rod 19.
Lorsque le canon 4 est relâché, le ressort récupérateur 29 se trouve en état comprimé et repoussera le canon jusqu'à venir chambrer la cartouche 7 qui se trouve en attente dans la cavité de réception 6, ce qui est illustré à la figure 6. Le pistolet est alors prêt pour le premier tir. La figure 7 illustre schématiquement le moment directement après la percussion. Ici, une pression a été exercée sur la détente 10, ce qui a provoqué le basculement du bras d'actionnement 15 vers le haut en poussant avec sa came 24 contre l'ergot 25 de la biellette 19 qui alors est légèrement soulevée de sorte que le pion de guidage 22 se trouve dans la branche horizontale de la fente en L et le chien 11 est libéré en repoussant la biellette sous l'action du ressort 12. L'extrémité de percussion du chien vient alors pénétrer dans l'orifice 31 de la paroi arrière 30 de la cavité de réception pour percuter la cartouche 7 se trouvant dans la chambre de tir 5 du canon 4. When the barrel 4 is released, the recuperating spring 29 is in a compressed state and will push the barrel until it comes to chamber the cartridge 7 which is waiting in the receiving cavity 6, which is illustrated in FIG. gun is then ready for the first shot. Figure 7 schematically illustrates the moment directly after the percussion. Here, pressure was exerted on the trigger 10, which caused the actuating arm 15 to tilt upwards by pushing with its cam 24 against the lug 25 of the rod 19 which is then slightly raised so that the guiding pin 22 is in the horizontal branch of the L-shaped slot and the dog 11 is released by pushing the link under the action of the spring 12. The hammer end of the dog then enters the hole 31 of the rear wall 30 of the receiving cavity for striking the cartridge 7 located in the firing chamber 5 of the barrel 4.
L'amorce de la cartouche est ainsi allumée et déclenche une combustion explosive dans la chambre. La balle 7' est expulsée tout en entraînant le canon par la friction entre la paroi interne de celui-ci et la balle. Par ailleurs, le canon est de préférence strié de manière classique afin d'imprimer une rotation à la balle sur elle-même pour la stabiliser en vol. The primer of the cartridge is thus lit and triggers an explosive combustion in the chamber. The ball 7 'is expelled while driving the barrel by friction between the inner wall thereof and the ball. On the other hand, the barrel is preferably streaked in a conventional manner to impart a rotation to the ball on itself to stabilize it in flight.
Lors du déplacement du canon vers sa position avancée, la lame d'éjection 44 est entraînée par le canon 4 sur une petite distance déterminée par la longueur de ses fentes de guidage 48 pour que sa boucle élastique 45 ne soit plus en face de l'ergot latéral 47 sur la paroi arrière 30 de la cavité de réception 6 afin de pouvoir éjecter la douille 7' de la cavité dès que l'ouverture d'éjection 8' soit dégagée. Dès que la douille 7' est éjectée, une nouvelle cartouche 7 monte dans la cavité de réception 6 pour être chambrée lorsque le canon 4 revient à sa position reculée par l'effet de l'action du ressort récupérateur 29. When moving the barrel towards its advanced position, the ejection blade 44 is driven by the barrel 4 over a small distance determined by the length of its guide slots 48 so that its elastic loop 45 is no longer in front of the barrel 4. lateral lug 47 on the rear wall 30 of the receiving cavity 6 in order to be able to eject the socket 7 'from the cavity as soon as the ejection opening 8' is disengaged. As soon as the bushing 7 'is ejected, a new cartridge 7 rises in the receiving cavity 6 to be chambered when the barrel 4 returns to its retracted position by the effect of the action of the recuperating spring 29.
Par la suite, le réarmement se fait de manière automatique lorsque le canon se déplace vers sa position avancée en faisant basculer le levier pivotant 40. Les figures 8 à 13 et 15A à 15B montrent un mode de réalisation d'un chargeur 9 adapté au pistolet selon l'invention. Le chargeur comporte une plaque d'élévation 51 des cartouches qui est constamment sollicitée vers le haut par un ressort de pression 52. Dans sa partie supérieure, le chargeur 9 est rétréci pour ne laisser passer qu'une cartouche 7 à la fois dans la cavité de réception 6. L'ouverture vers le haut est couverte par un organe rotatif 53 présentant la forme d'un étrier escamotable. Subsequently, the rearming is done automatically when the barrel moves to its advanced position by tilting the pivoting lever 40. Figures 8 to 13 and 15A to 15B show an embodiment of a charger 9 adapted to the gun according to the invention. The magazine comprises a cartridge raising plate 51 which is constantly urged upwards by a pressure spring 52. In its upper part, the magazine 9 is narrowed so as to allow only one cartridge 7 to pass through the cavity at a time. The upward opening is covered by a rotatable member 53 in the form of a retractable stirrup.
L'étrier escamotable 53 est montré à la figure 15A dans sa position de fermeture et dans la figure 15B dans sa position d'ouverture. Les deux branches parallèles de l'étrier sont montées pivotantes de part et d'autre de l'ouverture à l'extrémité haute du chargeur 9.  The retractable stirrup 53 is shown in FIG. 15A in its closed position and in FIG. 15B in its open position. The two parallel branches of the caliper are pivotally mounted on both sides of the opening at the upper end of the loader 9.
L'une des branches de l'étrier 53 est pourvue d'une patte 53 ' s 'étendant vers le bas pour pénétrer dans une fente de guidage 9 prévue sur la partie haute du chargeur 9. Cette patte 9 est apte à coopérer avec un organe élastique sous forme d'un ressort en épingle 54 disposé dans l'évidement 2' de la crosse 2 recevant le chargeur 9.  One of the branches of the stirrup 53 is provided with a tab 53 'extending downwards to enter a guide slot 9 provided on the upper part of the magazine 9. This tab 9 is adapted to cooperate with a elastic member in the form of a pin spring 54 disposed in the recess 2 'of the butt 2 receiving the loader 9.
L'une des extrémités du ressort en épingle 54 vient lors de la mise en place du chargeur dans la crosse 2 appuyer contre la patte 53' de l'étrier 53 de manière à faire basculer l'étrier 53 de sa position fermée montrée à la figure 15A vers sa position ouverte montrée à la figure 15B. Le chargeur 9 reste ainsi ouvert lorsqu'il se trouve mis en place dans la crosse 2.  One end of the pin spring 54 comes when the charger is placed in the butt 2 press against the tab 53 'of the stirrup 53 so as to tilt the stirrup 53 from its closed position shown in FIG. Figure 15A to its open position shown in Figure 15B. The magazine 9 remains open when it is put in place in the stick 2.
Il doit être noté que les cartouches sont stockées dans le chargeur de sorte que leur axe longitudinal soit parallèle à l'axe A- A du canon lorsque le chargeur est inséré dans la crosse 2 du pistolet.  It should be noted that the cartridges are stored in the magazine so that their longitudinal axis is parallel to the axis A-A of the barrel when the magazine is inserted into the butt 2 of the pistol.
Le chargement des cartouches dans le chargeur est sensiblement facilité du fait que les cartouches peuvent être introduites dans le chargeur en appuyant par dessus sur chaque cartouche et non pas comme sur les chargeurs classiques en la poussant de derrière. Pour chaque introduction d'une nouvelle cartouche 7 dans le chargeur 9, il convient de fermer l'étrier 53 manuellement pour retenir les cartouches à l'intérieur du chargeur. Loading the cartridges into the magazine is noticeably easier because the cartridges can be fed into the magazine by pressing on each cartridge and not on conventional magazines by pushing it from behind. For each introduction of a new cartridge 7 in the charger 9, it is necessary to close the stirrup 53 manually to retain the cartridges inside the charger.
La plaquette d'élévation 51 présente à l'avant sur sa face supérieure un évidement 55 susceptible d'être disposé en face d'une fente (non représentée) sur la paroi avant du chargeur lorsque la plaquette 51 est montée à sa position la plus élevée après le tir de la dernière cartouche du chargeur. Un organe de butée sous forme d'une tige 56 montée coulissante dans la carcasse 1 est disposée devant le chargeur et comporte à son extrémité haute un crochet 57 faisant saillie dans la fente du chargeur. La tige 56 est à son extrémité inférieure pourvue d'un trou oblong 58 recevant un pion 59 qui délimite le déplacement de la tige. The lifting plate 51 has at the front on its upper face a recess 55 capable of being disposed opposite a slot (not shown) on the front wall of the charger when the plate 51 is mounted at its most high after firing the last cartridge from the magazine. A stop member in the form of a rod 56 slidably mounted in the carcass 1 is disposed in front of the loader and has at its upper end a hook 57 projecting into the slot of the loader. The rod 56 is at its lower end provided with an oblong hole 58 receiving a pin 59 which defines the displacement of the rod.
Lorsque la dernière cartouche du chargeur 9 a été tirée, le crochet 57 entre dans l'évidement de la plaque d'élévation et tire la tige 56 vers le haut de sorte que la face arrière du crochet forme une butée au canon 4 lorsque celui-ci revient depuis sa position avancée suite au tir de la dernière cartouche. Le pistolet se trouve alors dans l'état montré à la figure 12 avec le chien 11 armé, le canon en butée contre la tige 56 et l'ouverture d'éjection 8' reste ouverte vers la cavité de réception 6. Le tireur peut alors appuyer sur un bouton 60 (voir figure 14) pour libérer le chargeur afin de pouvoir le retirer et le charger de nouveau de cartouches ou pour le remplacer par un autre qui en contient.  When the last cartridge of the magazine 9 has been pulled, the hook 57 enters the recess of the elevation plate and pulls the rod 56 upwards so that the rear face of the hook forms a stop at the barrel 4 when the It returns from its advanced position after firing the last cartridge. The gun is then in the state shown in FIG. 12 with the dog 11 cocked, the barrel abutting against the rod 56 and the ejection opening 8 'remains open towards the receiving cavity 6. The shooter can then press a button 60 (see figure 14) to release the magazine so that you can remove it and re-load it or replace it with another one that contains it.
Le bouton 60 est par ailleurs lors de son actionnement apte à venir appuyer sur la patte 53' de l'étrier 53 afin de le faire basculer vers sa position de fermeture. The button 60 is also during its actuation adapted to come to press the tab 53 'of the stirrup 53 to tilt to its closed position.
Après qu'une nouvelle cartouche est montée dans la cavité de réception 6, le tireur tire la tige 56 vers le bas en agissant sur une manette 61 de manière à escamoter l'extrémité haute de la tige pour libérer le canon 4 qui alors est repoussé en arrière par le ressort de récupération 29. After a new cartridge is mounted in the cavity of receiving 6, the shooter pulls the rod 56 down by acting on a handle 61 so as to retract the upper end of the rod to release the barrel 4 which is then pushed back by the recovery spring 29.
Si l'on souhaite enlever une cartouche 7 qui se trouve dans la chambre de tir 5, il convient de tirer le canon vers sa position avancée et repousser la manette 61 vers le haut pour empêcher à l'aide de la tige de butée 56 le canon de revenir entièrement dans sa position reculée afin de rendre la cartouche accessible par l'ouverture d'éjection 8'.  If it is desired to remove a cartridge 7 which is in the firing chamber 5, it is necessary to pull the barrel towards its advanced position and push the lever 61 upwards to prevent using the stop rod 56 the gun to fully return to its retracted position to make the cartridge accessible through the ejection opening 8 '.
Le pistolet est avantageusement pourvu d'un mécanisme de sécurité classique qui verrouille le chien 11 en agissant sur la biellette 19 de l'extérieur pour la bloquer à l'aide d'un petit levier de verrouillage 62 sur le côté du pistolet. Ce levier peut être tourné dans un sens ou dans l'autre pour verrouiller et déverrouiller le chien.  The gun is advantageously provided with a conventional safety mechanism that locks the dog 11 by acting on the rod 19 from the outside to block it with a small locking lever 62 on the side of the gun. This lever can be rotated one way or the other to lock and unlock the dog.
