Definitions
- the present invention relates to firearms, and more particularly to double barrel guns superimposed.
- Firearms in the variety of rifles have existed in many different forms and types for several decades. Different types of rifles have been developed for different types of shots. For example, and without limitation, there are smooth single-hinge guns, side-by-side smooth double-barreled rifles, superimposed smooth two-barreled rifles, single-shot smooth-action guns, gun guns semiautomatic rails, as well as various other types of smooth guns.
- the technology of smooth guns continues to evolve to meet the different needs of shooting enthusiasts. A large number of factors are taken into account in the design of smooth guns, such as appearance, weight, feel, ease of use, end use and individual preferences of the fencers.
- Especially shotgun double-barreled rifles are extremely popular among shooters.
- Super-smooth two-barrel guns are particularly suitable for pigeon shooting.
- the present invention relates to improvements made to two superposed smooth guns.
- the overall weight of a super-smooth two-barreled shotgun represents a major problem for all models and all types of smooth barrel rifles of this type.
- the lighter the shotgun the easier it will be to handle it.
- the weight is particularly important.
- the main object of the present invention is to provide a two-barreled rifle apparatus that utilizes a hinge assembly that absorbs the rearwardly-oriented compressive elastic force of a spring of a detent assembly, which reverses such a force and reorients the force towards the anterior portion of the firearm for the purpose of actuating the striker.
- Another object of the invention is to provide a two-barreled rifle apparatus which involves a firing pin which is loaded by moving a helical spring toward the front portion of the rifle.
- Another object of the invention is to provide additional security so that, when the trigger is not pressed and the linear hammer attempts to move toward the rear end of the firearm, the Linear hammer is blocked by the trigger and will not give rise to a discharge.
- each linear hammer will systematically come into contact with a front portion of the trigger as the fingering (tail) trigger will remain in the lower position (front position). In this case, there is no action possible linear hammers on the rockers and therefore no percussion.
- the stroke of moving parts is short.
- the combination of high speed (proportional acceleration) and reduced stroke provides the fastest percussion times, on the order of 0.0018 seconds.
- One aspect of the present invention involves a unique reverse direction detent assembly.
- Each main coil spring of the linear hammer is cocked by compressing the spring toward the end of the firearm corresponding to the mouth.
- the spring of one of the linear hammers relaxes and exerts a force directed rearward on the joint assembly which, in turn, redirects the force towards a striker in the direction towards the anterior portion or the end of the smooth-barreled rifle corresponding to the mouth. Thanks to this unique detent assembly, a unique safety mechanism can be obtained (which will be described below).
- a shotgun apparatus 30 generally comprises a section 32 corresponding to the barrel disposed at the front or distal end of the firearm and a section 34 corresponding to the rocker / butt, disposed at the rear end or proximal of the shotgun apparatus.
- the section 32 corresponding to the barrel includes a unit block 60 to which are fixed an upper barrel 62 and a lower barrel 64.
- a pair of ejection assemblies 56, 58 is also housed in the section 32 corresponding to the barrel.
- the rocker section 34 encloses the trigger assembly 38, the locking system 100, the internal cocking links, the security system 200, and various other operating parts of the smooth-bore rifle apparatus 30.
- the butt of the shotgun is attached to the rear portion of the carcass.
- the smooth-barreled rifle apparatus comprises in one embodiment, a two-barreled, superimposed shotgun.
- the section 32 corresponding to the barrel comprises a first barrel or upper barrel 62 (see FIG. figure 3 ) arranged in alignment with a second barrel or lower barrel 64, while being mounted directly on the latter.
- the over-and-under shotgun rifle 30 further comprises an end 36 occupied by the buttstock, which may include a recoil pad, and an end 37 occupied by the mouth.
- the firearm 30 further includes a detent assembly 38 for discharging the firearm and a lever actuated locking system 40 for opening the breech of the shotgun apparatus.
- the portion 32 corresponding to the barrel ends at the end of the shotgun, occupied by the mouth.
- a hinge assembly 42 which is defined in part by a male hinge portion 46 (see FIG. figure 7 ) formed on the section 34 corresponding to the rocker and by a female hinge portion 48 (see figure 8 ) formed on the monoblock unit 60 of the section 32 corresponding to the barrel of the particularly smooth rifle apparatus.
- a male hinge portion 46 On the male joint portion 46 is defined a curved abutment zone 44 (i.e., a curved track 44).
- the abutment zone 44 further includes a convex abutment surface 45 which provides a main bearing surface for sliding contact with a corresponding concave abutment surface 47 (see FIG. figure 8 ) formed within the female hinge portion 48 on the one-piece unit 60.
- the male joint portion may comprise a pair of abutment zones 44 and abutment surfaces 45, 47 formed on either side of the firearm 30.
- the abutment zones 44 and the surfaces stop 45, 47 serve as joint and support surface for the articulation of section 32 corresponding to the barrel relative to the section 34 occupied by the rocker / butt and to absorb the recoil force of the firearm during the discharge.
- the hinge assembly 42 defines a pivot axis 50 (see FIG. figure 3 ) which is remote or spaced from the abutment zones 44. A joint proper does not exist at the pivot axis 50.
- the first curved abutment surface 45 and the second curved abutment surface 47 see FIG.
- the abutment zone or the curved track 44 is capable of absorbing the totality of the recoil force generated during the discharge of the firearm. There is no need for a second stop zone or additional stop zone, as is the case with conventional two-barreled guns. Further, since two separate abutment surfaces are unnecessary, it is not necessary to coordinate the tolerances with respect to different and spatially separated contacting surfaces. Traditionally, the tolerances of two or more abutment surfaces must be precisely adjusted so that one abutment surface does not support a greater load than that supported by the other abutment surface. In addition, after repeatedly discharging, the moving parts and the lever mechanism of the shotgun will relax.
- Another important advantage related to the curved track or to the abutment zone 44 lies in the fact that the curved track 44 itself provides the articulation or bearing surfaces against which the two portions of the shotgun come into contact. arrange for articulation purposes.
- the pivot axis 50 (see FIG. figure 3 ) defined by the curved track or by the abutment zone 44 is spaced from the actual articulation surfaces (that is to say the abutment surfaces 45, 47). Accordingly, the actual positioning of the pivot axis 50 should not be located at a location on the smooth-bore rifle apparatus corresponding to a substantial amount of structure.
- the defined pivot axis 50 may correspond to a location where no structure exists (i.e., below the lowest structure of the firearm) depending on the actual radius of the firearm. the abutment area 44. No trunnion itself and no other articulation device is required at the pivot axis 50. In this way, a smooth-bore rifle having a profile can be obtained. lower. If a specific trunnion or bushing were required to locate at the pivot point 50, a substantial structure would be needed on the smooth-barrel rifle surrounding the pivot point which would in turn require an overall height plus dimension. important of the shotgun. As a result, the curved track 44 gives rise to a rifle apparatus that is smoother, lighter and easier to handle.
- ejection assemblies 56, 58 are shown operatively mounted on the one-piece unit 60 of the section 32 corresponding to the barrel.
- the monobloc unit 60 provides the first part of the guns 62, 64 and serves as an interface with the section 34 corresponding to the rocker / butt.
- the unitary unit 60 furthermore has the object of rigidly connecting the upper barrel 62 and the lower barrel 64 of the two barrel rifle apparatus.
- Ejection heads 66, 68 are intended to undergo an outward thrust with a force sufficient to discharge from the monobloc unit in its entirety a consumed lead cartridge. If, for whatever reason, a discharge of the pellet cartridge were not obtained, the ejection heads 66, 68 would push the pellet cartridges away from the base end 70 of the cartridge. the monoblock unit sufficiently (approximately 10 mm) to allow the shooter to easily remove the cartridge or cartridges from the chamber.
- the ejection system 56 includes an ejection spring 76 which imparts outward pretensioning to the other ejection elements.
- a guide 72 of the ejection spring holds the spring in place.
- the combination of spring 76 and spring guide 72 is inserted into appropriately sized openings in the barrels and is held in place by appropriate stops formed within the barrel assembly.
- a linear ejection hammer 77 is coupled to the ejection system.
- a cam link 79 is part of the ejection system and is guided by the flip-flop of the firearm.
- the linear ejection hammer 77 acts as a hammer and strikes the head of the cam joint 79 when ejecting the cartridges.
- the cam joint 79 further includes a shoulder 80 which bears against the one-piece unit 60 for the purpose of limiting the movement of the ejection system 56.
- the ejection head 66 is attached to the cam hinge 79 and is used to force the cartridge out of the chamber.
- An ejection head pin 67 holds the ejection head 66 in the state coupled to the cam hinge 79.
- An ejection trigger 82 is used to retain the spring and linear hammer 77 after firing.
- An ejector trigger hinge 82 is used for decoupling the ejection trigger after opening the rifle.
- a timing adjusting screw 86 is used to adjust the timing of the ejection between the two guns.
- a cocking lever 90 rotates forward (see figure 9 ) and makes contact with the ejector trigger 82, causing the trigger 82 to turn clockwise so that it can contact the notch 83 of the linear ejector hammer 77.
- the ejection trigger 82 makes contact with the notch 83 of the linear ejection hammer 77 in order to maintain the linear ejection hammer 77 in position.
- the cam portion 88 of the cam joint 79 is guided by the tracks in the rocker.
- the spring 76 When the linear ejection hammer 77 is grasped by the ejector trigger 82, the spring 76 does not have the possibility of exerting subsequent prestressing on the ejector outwardly. However, the tracks in the rocker force said spring to move outwardly over a distance of approximately 3 mm. This displacement is used to eject the consumed cartridge from the chamber.
- the end of the ejection trigger articulation 84 comes into contact with the cocking lever. 90. This contact forces the ejector trigger 82 to move away from the linear ejector hammer 77.
- a synchronization adjustment screw 86 is placed (see figure 10 ) in the ejector trigger 82.
- the adjusting screw 86 is based on the ejector trigger hinge 84 and affects the moment of decoupling of said hinge.
- the locking system 100 is represented in the Figures 15-22 .
- the locking system 100 is shown in the unlocked position in the Figures 15 to 18 and it is represented in the locked position in the Figures 19 to 22 .
- the upper lever disconnect device 102 is used to release the upper lever 104 when the rifle is closed.
- a spring loaded plunger (not shown) is held within the upper lever 104.
- the upper lever 104 is rotated counterclockwise (as shown in FIG. in figure 15 ) approximately 30 degrees. In this position, the plunger in the upper lever is disposed in alignment with the hole in the flip-flop containing the disconnection device 102 of the upper lever.
- the disconnect device 102 of the upper lever is pushed forward by the plunger into the upper lever 104. When the plunger is disposed so that it protrudes in the rocker, the rotation of the upper lever is blocked.
- the upper lever 104 is also used as a crank arm or lever for moving the locking bolts 106 to insert them into the slots or grooves 120 in the one-piece unit 60 or to remove them.
- the disconnector 108 of the rocker 140 interfaces with the upper lever 104.
- the disconnector 108 of the rocker 140 is pushed back or returned by cam back by the upper lever 104 in the rocker 140 (see Figures 23-31 ).
- the strikers 135 have the opportunity to retreat away from the primer or primers consumed after the shots. In this way, the firing pins are also blocked when the trigger fails while the rifle is in an unlocked position.
- a spring (not shown) pushes the disconnector 108 of the rocker 140 back into its locked position.
- a disconnect device 110 of the trigger articulation 84 is screw-threaded to a transverse member 112 (see FIG. figure 22 ) which extends between locking bolts 106.
- the trigger hinge disconnector 110 includes a rear end surface 111 which contacts the trigger hinge 84 to press the trigger hinge 84 towards the hinge joint. 'back.
- a locking cam 114 is attached to the upper lever 104 via a fastener (not shown) such as a screw or a spindle, as will be understood by those skilled in the art.
- a cylindrical body 116 extending downwardly from the lever 104 is coupled to the locking cam 114.
- a groove 118 is formed in the cylinder 116, in which an end of the disconnector device of the rocker 108 is housed.
- the lever 104 is rotated, the locking cam 114 rotates, so that the extension member 116 prints to the locking bolts 106 (which are coupled to each other by the transverse member 112) ( see it figure 18 ) reciprocating with respect to the unitary unit.
- Locking bolts 106 are inserted into slots 120 formed in the one-piece unit 60. Locking bolts 106 prevent opening of the lever mechanism after the firearm bolt has been closed. Locking bolts 106 encompass a surface Angle or conical outer member 107 which facilitates contacting of the locking bolts 106 with the slots 120 appropriately sized in the unitary unit. When the edge contact point 107 is subjected to wear, the locking bolts 106 are spring loaded to maintain a tight fit.
- the transverse member 112 holds the locking bolts 106 together and forces them to move in the form of a unit.
- the locking bolts 106 and the transverse member 112 may be machined or otherwise made to provide a unit.
- the combination of the locking bolts 106 and the transverse member 112 can be made by assembling separate pieces.
- a pair of screws 113 (only one shown) holds together the locking bolts 106 and the transverse member 112.
- the unitary unit 60 is designed to provide an interface with the flip-flop (i.e. flip-flop 34 as indicated in FIG. figure 3 ) and with the locking system 100, on the one hand and with the barrel tubes 62, 64 (see figure 3 ), on the other hand.
- the flip-flop i.e. flip-flop 34 as indicated in FIG. figure 3
- the locking system 100 on the one hand and with the barrel tubes 62, 64 (see figure 3 ), on the other hand.
- the firing system 130 according to the invention is shown.
- the firing system 130 is shown before pressing the trigger.
- the firing system 130 is shown after pressing the trigger.
- the firing system 130 generally comprises a cocking lever 90, a connection hinge 132, a firing pin assembly 134, a trigger joint 136, a linear hammer 138, a rocker 140, a trigger 142, an expansion joint 144 and a mass of inertia 146.
- the assembly, operation and construction of these sub-parts of the firing system 130 are discussed below.
- the cocking lever 90 is used to cock the firearm once a shot has been made. A pocket is cut in the rocker so that the cocking lever 90 is housed therein.
- the cocking lever rotates around the pivot point 145, causing the portion to fall. front of the cocking lever 90 (giving rise to the backward movement of the linear hammer 138).
- the front of the cocking lever 90 is pushed upwards by the barrel, which causes it to rotate around the curved track 44. During said rotation, the cocking lever 90 pulls the linear hammer 138 towards the front of the firearm.
- the joint of trigger 136 falls into a trip position over the linear hammer 138.
- the preloaded springs of the firing pin 135 press the end of the striker 135 to engage the upper portion of the rocker 140 in a position that grips the trigger hinge 136 and holds it in place until next shot.
- connection hinge 132 couples the cocking lever 90 to the linear hammer 138.
- the connection hinge 132 is attached to the cocking lever at the pivot point 147.
- a spring 139 (not shown in FIGS. Figures 23 to 31 ) press the linear hammer 138 towards the rear of the rifle.
- the trigger articulation 136 is hooked upwardly to the linear hammer 138 and holds the latter in position until it is pressed. trigger.
- the connection hinge 132 moves approximately in a straight line (even if the connection of the connection hinge 132 to the cocking lever 90 gives rise to a slight vertical movement of the cocking lever, such a movement is not enough to trigger any kind of problem).
- the firing pin assembly 134 comprises a striker 135 and the spring 137 of the firing pin.
- the striker spring puts the rocker 140 in the prestressing state in a position of shoot. This movement is used to arm the rifle.
- Each striker 135 limits the movement of all the elements associated with the striker, including the rocker 140 and the linear hammer 138. The movement of the striker 135 is limited by a pin (not shown) which is inserted into a notch 141. L
- the end end of striker 135 (not shown) is narrowed and contacts the primer of the fired cartridge, as will be understood by those skilled in the art.
- the trigger hinge 136 is used to reduce charge transfer on the trigger surfaces.
- the linear hammer 138 when in the fully armed position, develops a substantial horizontal load.
- the surface formed between the trigger hinge 136 and the linear hammer 138 forms an angle such that the strong horizontal force from the linear hammer generates a small vertical force which applies an upward rotational force to the trigger hinge 136 to releasing the linear hammer 138.
- the rocker 140 limits the upward rotation of the trigger articulation 136.
- the linear hammer 138 is held against the connection joint 132 by a linear hammer nut 143. When using the rifle to fire, the trigger rotates the rocker 140 which in turn releases the trigger link 136. The reduction of forces caused by the trigger articulation 136 allows to obtain a lighter and more uniform movement of the trigger.
- a spring preloading force imparted by the helical spring 139 causes the linear hammer 138 to strike the rocker 140, which in turn transfers the energy to the rocker 140.
- the rocker 140 after the inversion of the energy or pulse, strikes the striker 135 and moves striker 135 towards the particular primer (not shown).
- the rocker 140 has two main functions. In the first place, it transfers the energy of the linear hammer 138, directed towards the rear, to the energy of the firing pin 135, oriented towards the front. Second, it acts as a trigger that allows the trigger to relax the system.
- the expansion joint 144 allows the expansion of the trigger 142 and transfers the rotation of the trigger to the rocker 140.
- a front portion of the trigger 142 is used to grip the linear hammer 138 when the trigger shows a failure when it is not supported. not on the relaxation.
- a first frontal contacting surface 152 comes into contact with one of the rockers 140 to a trigger engaging surface 154 (see FIG. figure 29 ) as a function of knowing the rocker 140 which has been biased towards safety (as described below).
- the rocker which has not been affected by the trigger is pushed aside via its associated linear hammer 138. In this way, the articulation of the trigger 144 can move forward. and contacting the second rocker 140 with one of the second lateral contacting surfaces 156.
- the mass of inertia 146 is used as a counterweight. During the recoil of the rifle, the mass of inertia pulls the trigger articulation 144 towards the rear of the rifle (by overcoming the prestressing force exerted by the spring 150) to disconnect it from the rocker 140. The mass of inertia 146 is free to move in the vertical direction through its positioning in a U-shaped saddle 158. The mass of inertia 146 prevents the rotation of the trigger around its pivot point when the rifle is for example lowered.
- An articulation spring of the trigger 150 places the trigger joint 144 in pretensioned state in a forward facing position. The spring also returns the trigger 142 in the position corresponding to a lack of fire.
- a drum 170 having an adjustable length is attached to the section 32 corresponding to the barrels and interfaces with the section 34 occupied by the rocker.
- the barrel 170 includes a pair of opposed posts 172 which are inserted into corresponding slots 174 (shown in dashed lines in FIG. 32), so that the opposing tabs 172 (only one shown in FIG. locations they can occupy in order to place the barrel 170 in an appropriate position.
- a spring preloaded latch 176 pivots about the pivot point 178 to move away. and contacting a hook 180 relative to a corresponding female area on a downwardly extending attachment block 182 (shown in dashed lines in FIG.
- the shank 170 and the rocker 34 reciprocally contact each other along a first vertical surface 184 and along a lower curved guide or abutment surface 186.
- these surfaces in combination with the surface d 145 (which comes into contact with a corresponding arcuate shaped surface formed in the unitary unit) are all disposed on one side of a defined pivot point of the barrel assembly 32 with respect to the rocker section 34.
- the rocker defines surfaces 145 and the corresponding abutment surface with respect to the abutment surface 186.
- the surfaces on the barrel, which abut against the rocker 34 to provide stop zones 184, 186 act in combination with the bearing surface 47 (see FIG.
- FIG 8 formed in the monobloc unit for gasoline "clamp together" the surfaces on the rocker 34 which are part of the abutment areas 184, 186, and the bearing surface 145. This provides a tight fit for the created joint by surfaces 186 (comprising both the appropriate portion of drum 170 and the appropriate portion of flip-flop 34) and curved track 145 formed in flip-flop 34.

Description
La présente invention concerne les armes à feu, et plus particulièrement des fusils à deux canons lisses superposés.The present invention relates to firearms, and more particularly to double barrel guns superimposed.
Des armes à feu faisant partie de la variété des fusils existent dans un grand nombre de formes et de types différents depuis plusieurs dizaines d'années. Différents types de fusils ont été mis au point pour différents types de tirs. Par exemple, et sans aucune limitation, il existe des fusils à canons lisses à charnière à un coup, des fusils à deux canons lisses disposés côte à côte, des fusils à deux canons lisses superposés, des fusils à canons lisses uniques à répétition commandée, des fusils à canons lisses semi-automatiques, ainsi que divers autres types de fusils à canons lisses. La technologie des fusils à canons lisses continue d'évoluer pour répondre aux différents besoins que manifestent les adeptes du tir. Un grand nombre de facteurs sont pris en compte dans la conception des fusils à canons lisses, tels que l'aspect, le poids, le toucher, la facilité d'utilisation, l'utilisation finale ainsi que les préférences individuelles manifestées par les tireurs.Firearms in the variety of rifles have existed in many different forms and types for several decades. Different types of rifles have been developed for different types of shots. For example, and without limitation, there are smooth single-hinge guns, side-by-side smooth double-barreled rifles, superimposed smooth two-barreled rifles, single-shot smooth-action guns, gun guns semiautomatic rails, as well as various other types of smooth guns. The technology of smooth guns continues to evolve to meet the different needs of shooting enthusiasts. A large number of factors are taken into account in the design of smooth guns, such as appearance, weight, feel, ease of use, end use and individual preferences of the fencers.
Des fusils à deux canons lisses superposés en particulier sont extrêmement populaires parmi les adeptes du tir. Des fusils à deux canons lisses superposés sont particulièrement appropriés pour le tir au pigeon. La présente invention concerne des améliorations apportées à des fusils à deux canons lisses superposés.Especially shotgun double-barreled rifles are extremely popular among shooters. Super-smooth two-barrel guns are particularly suitable for pigeon shooting. The present invention relates to improvements made to two superposed smooth guns.
Le poids global d'un fusil à deux canons lisses superposés représente un problème majeur pour tous les modèles et tous les types de fusil à canons lisses de ce type. Plus léger sera le fusil à canon lisse, plus aisée sera sa manipulation. Lorsque, lors d'une compétition de tir, on donne la primauté à la rapidité de manipulation et de visée, comme c'est le cas dans le tir au pigeon, le poids est particulièrement important.The overall weight of a super-smooth two-barreled shotgun represents a major problem for all models and all types of smooth barrel rifles of this type. The lighter the shotgun, the easier it will be to handle it. When, during a shooting competition, one gives primacy to the speed of manipulation and aiming, as is the case in pigeon shooting, the weight is particularly important.
Un autre problème majeur lié à la conception réside dans le toucher du fusil à deux canons lisses superposés. De manière spécifique, plus lisse sera le fusil, plus aisées seront sa manipulation et sa maîtrise. Des facteurs tels que la hauteur globale, la largeur et le contour du fusil à canons lisses contribuent à ses caractéristiques de lissé et de « toucher ».Another major problem related to the design lies in the touch of the double-barreled shotgun. Specifically, smoother will be the rifle, more affluent will be his manipulation and mastery. Factors such as the overall height, width and contour of the smooth guns contribute to its smoothness and "feel" characteristics.
Un autre facteur important encore dans le cadre des fusils à deux canons superposés concerne l'aspect global de l'arme à feu. En général, un fusil plus mince et plus lisse offrira un meilleur aspect. Des modèles lisses de ce type font en sorte que le fusil s'avère aisé à maîtriser et à manipuler. Des modèles de plus grandes dimensions s'avèrent plus encombrants et plus massifs, et par conséquent plus difficiles à manipuler et à maîtriser.Another important factor in the case of double-barreled guns is the overall appearance of the firearm. In general, a thinner and smoother rifle will look better. Smooth models of this type make the rifle easy to control and handle. Larger models are more bulky and more massive, and therefore more difficult to handle and control.
Le brevet
L'objet principal de la présente invention est de procurer un appareil de fusil à deux canons superposés qui utilise un assemblage d'articulation qui absorbe la force élastique de compression orientée vers l'arrière d'un ressort d'un assemblage de détente, qui inverse une telle force et qui réoriente la force en direction de la portion antérieure de l'arme à feu dans le but d'actionner le percuteur.The main object of the present invention is to provide a two-barreled rifle apparatus that utilizes a hinge assembly that absorbs the rearwardly-oriented compressive elastic force of a spring of a detent assembly, which reverses such a force and reorients the force towards the anterior portion of the firearm for the purpose of actuating the striker.
Un autre objet de l'invention est de procurer un appareil de fusil à deux canons superposés qui implique un percuteur qui est chargé en déplaçant un ressort hélicoïdal en direction de la portion antérieure du fusil.Another object of the invention is to provide a two-barreled rifle apparatus which involves a firing pin which is loaded by moving a helical spring toward the front portion of the rifle.
Un autre objet de l'invention est de procurer une sécurité supplémentaire de telle sorte que, lorsqu'on n'appuie pas sur la détente et lorsque le marteau linéaire tente de se déplacer vers l'extrémité arrière de l'arme à feu, le marteau linéaire est bloqué par la détente et ne va pas donner lieu à une décharge.Another object of the invention is to provide additional security so that, when the trigger is not pressed and the linear hammer attempts to move toward the rear end of the firearm, the Linear hammer is blocked by the trigger and will not give rise to a discharge.
Les objets indiqués ci-dessus sont réalisés à l'aide d'un appareil d'arme à feu selon la revendication 1 ainsi que d'un procédé selon la revendication 6.The objects indicated above are made using a firearm apparatus according to
L'action de chaque ressort des marteaux linéaires se faisant d'avant en arrière, chaque marteau linéaire entrera systématiquement en contact avec une portion frontale de la détente tant que le doigté (queue) de détente restera en position basse (position avant). Dans ce cas précis, il n 'y a pas d'action possible des marteaux linéaires sur les basculeurs et donc pas de percussion.The action of each spring linear hammers going back and forth, each linear hammer will systematically come into contact with a front portion of the trigger as the fingering (tail) trigger will remain in the lower position (front position). In this case, there is no action possible linear hammers on the rockers and therefore no percussion.
Le fait de bénéficier de marteaux à mouvement linéaire garanti une accélération des marteaux proportionnels à l'effort de compression des ressorts, ce qui n'est pas le cas avec des chiens rotatifs classiques propulsés par des poussoirs sous l'effet d'un ressort, la ligne d'action du poussoir de chien se rapprochant de l'axe de rotation du chien en cours d'armement de ce dernier.The fact of benefiting from linear movement hammers guarantees an acceleration of the hammers proportional to the compression force of the springs, which is not the case with conventional rotary dogs propelled by pushers under the effect of a spring, the line of action of the dog pusher approaching the axis of rotation of the dog during arming of the latter.
De plus, dans le cas de l'invention, la course des pièces en mouvement est courte. La combinaison de la grande vitesse (accélération proportionnelle) et de la course réduite permet d'obtenir des temps de percussion les plus rapides, soit de l'ordre de 0,0018 secondes.In addition, in the case of the invention, the stroke of moving parts is short. The combination of high speed (proportional acceleration) and reduced stroke provides the fastest percussion times, on the order of 0.0018 seconds.
Un aspect de la présente invention implique un assemblage unique de détente à direction inverse. Chaque ressort hélicoïdal principal du marteau linéaire est armé en comprimant le ressort en direction de l'extrémité de l'arme à feu correspondant à la bouche. Lorsqu'on appuie sur la détente, le ressort d'un des marteaux linéaires se relâche et exerce une force orientée vers l'arrière sur l'assemblage d'articulation qui, à son tour, réoriente la force en direction d'un percuteur dans la direction orientée vers la portion antérieure ou vers l'extrémité du fusil à canon lisse correspondant à la bouche. Grâce à cet assemblage de détente unique, on peut obtenir un mécanisme de sécurité unique (que l'on va décrire ci-dessous).One aspect of the present invention involves a unique reverse direction detent assembly. Each main coil spring of the linear hammer is cocked by compressing the spring toward the end of the firearm corresponding to the mouth. When the trigger is depressed, the spring of one of the linear hammers relaxes and exerts a force directed rearward on the joint assembly which, in turn, redirects the force towards a striker in the direction towards the anterior portion or the end of the smooth-barreled rifle corresponding to the mouth. Thanks to this unique detent assembly, a unique safety mechanism can be obtained (which will be described below).
La compacité de l'engagement des composants assure les fonctions essentielles de l'arme sans compromettre l'intégrité de la partie arrière.The compact engagement of the components ensures the essential functions of the weapon without compromising the integrity of the rear part.

Le système d'éjection 56 comprend un ressort d'éjection 76 qui confère une mise en état de précontrainte vers l'extérieur aux autres éléments d'éjection. Un guide 72 du ressort d'éjection maintient le ressort en place. La combinaison du ressort 76 et du guide de ressort 72 est insérée dans des ouvertures de dimensions appropriées pratiquées dans les canons et est maintenue en place par des arrêts appropriés formés à l'intérieur de l'assemblage de canons. Un marteau linéaire d'éjection 77 est couplé au système d'éjection. Une liaison à came 79 fait partie du système d'éjection et est guidée par la bascule de l'arme à feu. Le marteau linéaire d'éjection 77 fait office de marteau et frappe la tête de l'articulation à came 79 lors de l'éjection des cartouches. L'articulation à came 79 englobe en outre un épaulement 80 qui s'appuie contre l'unité monobloc 60 dans le but de limiter le mouvement du système d'éjection 56.The
La tête d'éjection 66 est fixée à l'articulation à came 79 et est utilisée pour forcer la cartouche hors de la chambre. Une broche de tête d'éjection 67 maintient la tête d'éjection 66 à l'état couplé à l'articulation à came 79.The
Une gâchette d'éjection 82 est utilisée pour retenir le ressort et le marteau linéaire 77 après le tir. Une articulation de gâchette d'éjection 82 est utilisée pour le découplage de la gâchette d'éjection après l'ouverture du fusil. Une vis de réglage de synchronisation 86 est utilisée pour régler la synchronisation de l'éjection entre les deux canons.An
Lorsque l'arme à feu est en position ouverte, des cartouches sont chargées dans l'extrémité des canons occupée par la culasse. Lorsque le fusil est fermé, une section de came 88 de l'articulation à came 79 est guidée par les pistes dans la bascule et force les éléments d'éjection (c'est-à-dire la tête d'éjection 68, l'articulation à came 79 et le marteau linéaire d'éjection 77) en retour dans les canons. Le ressort d'éjection 76 exerce une mise en état de précontrainte constante sur les éléments d'éjection en direction de l'extrémité de l'arme à feu, occupée par la culasse. Lorsqu'on ouvre à nouveau l'arme à feu, alors que la cartouche n'a pas été tirée, le ressort d'éjection 76 pousse la cartouche à l'extérieur des canons jusqu'à une limite de course d'environ 10 mm.When the firearm is in the open position, cartridges are loaded into the end of the barrels occupied by the breech. When the rifle is closed, a

On utilise le dispositif de déconnexion de levier supérieur 102 pour libérer le levier supérieur 104 lorsque le fusil est fermé. Un piston-plongeur chargé par ressort (non représenté) est maintenu à l'intérieur du levier supérieur 104. Dans le but de déverrouiller le fusil, on fait tourner le levier supérieur 104 dans le sens contraire des aiguilles d'une montre (comme représenté en
Le levier supérieur 104 est également utilisé comme bras de manivelle ou comme levier pour le déplacement des boulons de verrouillage 106 afin de les insérer dans les fentes ou les rainures 120 dans l'unité monobloc 60 ou afin de les en retirer. Le dispositif de déconnexion 108 du basculeur 140 s'interface avec le levier supérieur 104. Lorsqu'on fait tourner le levier supérieur 104, le dispositif de déconnexion 108 du basculeur 140 est poussé en retour ou est renvoyé par came en retour par le levier supérieur 104 dans le basculeur 140 (voir les

Des boulons de verrouillage 106 viennent s'insérer dans des fentes 120 formées dans l'unité monobloc 60. Des boulons de verrouillage 106 empêchent l'ouverture du mécanisme à levier après la fermeture de la culasse de l'arme à feu. Les boulons de verrouillage 106 englobent une surface externe 107 angulaire ou conique qui facilite la mise en contact des boulons de verrouillage 106 avec les fentes 120 dimensionnées de manière appropriée dans l'unité monobloc. Lorsque le point de mise en contact au bord 107 est soumis à une usure, les boulons de verrouillage 106 sont chargés par un ressort pour maintenir un ajustage serré.Locking
Comme on l'a mentionné, l'élément transversal 112 maintient ensemble les boulons de verrouillage 106 et force ces derniers à se déplacer sous la forme d'une unité. Les boulons de verrouillage 106 et l'élément transversal 112 peuvent être usinés ou être réalisés d'une autre manière pour obtenir une unité. En variante, la combinaison des boulons de verrouillage 106 et de l'élément transversal 112 peut être fabriquée par assemblage de pièces séparées. Une paire de vis 113 (une seule étant représentée) maintient ensemble les boulons de verrouillage 106 et l'élément transversal 112.As mentioned, the
L'unité monobloc 60 est conçue pour procurer une interface avec la bascule (c'est-à-dire la bascule 34 comme indiqué en

Le système de tir 130 selon l'invention comprend en général un levier d'armement 90, une articulation de connexion 132, un assemblage de percuteurs 134, une articulation de gâchette 136, un marteau linéaire 138, un basculeur 140, une détente 142, une articulation de détente 144 et une masse d'inertie 146. L'assemblage, le fonctionnement et la construction de ces sous-parties du système de tir 130 sont abordés ci-dessous.The
Le levier d'armement 90 est utilisé pour armer l'arme à feu une fois qu'un tir a été effectué. Une poche est découpée dans la bascule pour que vienne s'y loger le levier d'armement 90. Lorsque l'arme à feu est déchargée, le levier d'armement effectue une rotation autour du point de pivotement 145, en faisant chuter la portion frontale du levier d'armement 90 (donnant lieu au mouvement vers l'arrière du marteau linéaire 138). Lorsqu'on ouvre l'arme à feu, l'avant du levier d'armement 90 est poussé vers le haut par le fût, ce qui provoque sa rotation autour de la piste bombée 44. Lors de ladite rotation, le levier d'armement 90 tire le marteau linéaire 138 en direction de l'avant de l'arme à feu. Lorsque l'arme à feu est proche d'une position complètement ouverte, l'articulation de gâchette 136 tombe dans une position de déclenchement par-dessus le marteau linéaire 138.The cocking
Les ressorts mis en état de précontrainte du percuteur 135 pressent l'extrémité du percuteur 135 pour que cette dernière entre en contact avec la portion supérieure du basculeur 140 dans une position qui saisit l'articulation de gâchette 136 et la maintient en place jusqu'au tir suivant.The preloaded springs of the
L'articulation de connexion 132 couple le levier d'armement 90 au marteau linéaire 138. L'articulation de connexion 132 vient se fixer au levier d'armement au point de pivotement 147. Un ressort 139 (non représenté dans les
L'assemblage de percuteurs 134 comprend un percuteur 135 et le ressort 137 du percuteur. Le ressort du percuteur met le basculeur 140 en état de précontrainte dans une position de tir. Ce mouvement permet d'armer le fusil. Chaque percuteur 135 limite le mouvement de tous les éléments associés au percuteur, y compris le basculeur 140 et le marteau linéaire 138. Le mouvement du percuteur 135 est limité par une broche (non représentée) qui vient s'insérer dans une encoche 141. L'extrémité extrême du percuteur 135 (non représentée) est rétrécie et entre en contact avec l'amorce de la cartouche faisant l'objet du tir, comme le comprendra l'homme de métier spécialisé dans la technique.The
L'articulation de gâchette 136 est utilisée pour réduire le transfert de charge sur les surfaces de la gâchette. Le marteau linéaire 138, lorsqu'il se trouve dans la position complètement armée, développe une charge horizontale substantielle. La surface ménagée entre l'articulation de gâchette 136 et le marteau linéaire 138 forme un angle de telle sorte que la force horizontale intense provenant du marteau linéaire génère une petite force verticale qui applique une force de rotation ascendante sur l'articulation de gâchette 136 pour libérer le marteau linéaire 138. Le basculeur 140 limite la rotation ascendante de l'articulation de gâchette 136. Le marteau linéaire 138 est maintenu contre l'articulation de connexion 132 par un écrou de marteau linéaire 143.
Lorsqu'on utilise le fusil pour tirer, la détente fait tourner le basculeur 140 qui libère à son tour l'articulation de gâchette 136. La réduction de forces provoquées par l'articulation de gâchette 136 permet d'obtenir un mouvement plus léger et plus uniforme de la détente.The
When using the rifle to fire, the trigger rotates the
Après le relâchement du marteau linéaire 138, une force de mise en état de précontrainte par ressort, conférée par le ressort hélicoïdal 139 (le ressort du marteau linéaire 139 est représenté dans les
L'articulation de détente 144 permet la rotation de la détente 142 et transfère la rotation de la détente au basculeur 140. Une portion frontale de la détente 142 est utilisée pour saisir le marteau linéaire 138 lorsque la gâchette manifeste une défaillance quand on n'appuie pas sur la détente. Il existe deux surfaces de mise en contact différentes sur l'articulation de détente 144. Lorsque les deux canons ne sont pas impliqués dans un tir, une première surface de mise en contact frontale 152 (voir les
La masse d'inertie 146 est utilisée comme contrepoids. Au cours du recul du fusil, la masse d'inertie tire l'articulation de détente 144 vers l'arrière du fusil (en surmontant la force de précontrainte exercée par le ressort 150) pour la déconnecter du basculeur 140. La masse d'inertie 146 est libre de se déplacer en direction verticale grâce à son positionnement dans une selle en U 158. La masse d'inertie 146 empêche la rotation de la détente autour de son point de pivotement lorsque le fusil est par exemple abaissé.The mass of
Un ressort d'articulation de la détente 150 met l'articulation de détente 144 en état de précontrainte dans une position orientée vers l'avant. Le ressort renvoie également la détente 142 dans la position correspondant à une absence de tir.An articulation spring of the
Un fût 170 possédant une longueur réglable vient se fixer à la section 32 correspondant aux canons et s'interface avec la section 34 occupée par la bascule. Le fût 170 englobe une paire de tenons opposés 172 qui sont insérés dans des fentes correspondantes 174 (que l'on représente en pointillé en figure 32), de telle sorte que les tenons opposés 172 (un seul étant représenté en figure 32) possèdent des emplacements qu'ils peuvent occuper afin de placer le fût 170 dans une position appropriée. Afin de fixer le fût 170 en place autour de la section de canon 32 et dans un arrangement de butée approprié par rapport à la section de bascule 34, un verrou 176 mis en état de précontrainte par ressort pivote autour du point de pivotement 178 pour écarter et mettre en contact un crochet 180 par rapport à une zone femelle correspondante sur un bloc de fixation 182 s'étendant vers le bas (que l'on représente en pointillé en figure 32). Le fût 170 et la bascule 34 entrent en contact réciproque de long d'une première surface verticale 184 et le long d'une surface de guidage ou de butée courbe inférieure 186. Il convient de noter que ces surfaces, en combinaison avec la surface d'appui 145 (qui entre en contact avec une surface de forme arquée correspondante formée dans l'unité monobloc) sont toutes disposées d'un côté d'un point de pivotement défini de l'assemblage de canon 32 par rapport à la section de bascule 34. Il convient de noter en outre que la bascule définit des surfaces 145 et la surface de butée correspondante par rapport à la surface de butée 186. Les surfaces sur le fût, qui viennent buter contre la bascule 34 pour procurer des zones de butée 184, 186 agissent en combinaison avec la surface d'appui 47 (voir la
Le serrage de l'articulation créée par les surfaces susmentionnées peut être réglé. Une vis de réglage 190 est prévue dans le fût 170. La vis de réglage 190 peut être utilisée pour faire varier la pression exercée par le fût 170 sur la bascule 34 dans les zones de butée 184, 186. En faisant tourner la vis de réglage 190, on modifie la surface du fût s'appuyant contre le bloc de fixation 182, ce qui fait varier à son tour la pression exercée sur les zones de butée 184, 186. Il convient de noter que la fente 174 est allongée pour permettre une certaine aptitude de réglage par rapport aux surfaces de butée 184, 186.Clamping of the hinge created by the aforementioned surfaces can be adjusted. A set screw 190 is provided in the
Un autre aspect encore de l'articulation ou du mécanisme à levier concerne les surfaces qui s'appuient les unes contre les autres dans la zone de butée 192 lorsque le mécanisme à levier se ferme. Lors de la fermeture du mécanisme à levier de l'arme à feu, une surface de l'unité monobloc 60 vient s'appuyer contre une surface sur la bascule 34 dans la zone de butée 192. Pour régler le moment correspondant à l'arrêt du mécanisme à levier, on peut englober une pièce rapportée en acier d'un côté de la zone de butée 192 pour régler l'endroit auquel les surfaces de butée se rencontrent.Yet another aspect of the hinge or lever mechanism is the surfaces that abut against one another in the stop zone 192 when the lever mechanism closes. When the lever mechanism of the firearm is closed, a surface of the
