Abstract

The device has right and left pins (3d, 3g) forming two bosses (6d, 6g), respectively for retention of a missile in a barrel (1) of a weapon. The pins are situated symmetrically on both sides of a vertical reference axis (XX) passing via a center of the barrel, and are introduced across the barrel support. The pins have screws (4d, 4g) with adjustment knobs (5d, 5g) that adjust the heights of the bosses.

Description

L'invention concerne un dispositif pour corriger la trajectoire des projectiles dans une réplique d'arme du type «Air Soft Gun® » ou « Softair® » qui tire des billes de plastique très légères d'un diamètre d'environ 6 millimètres. Elle concerne, plus précisément, la correction de la trajectoire d'un projectile en plastique en sortie du canon d'une réplique d'arme. La correction de la trajectoire du projectile peut se faire aussi bien verticalement que horizontalement, sur une réplique d'arme longue comme sur une réplique d'arme de poing.The invention relates to a device for correcting the trajectory of the projectiles in a replica weapon of the "Air Soft Gun®" or "Softair®" type which fires very light plastic balls with a diameter of about 6 millimeters. It concerns, more precisely, the correction of the trajectory of a plastic projectile at the exit of the barrel of a replica weapon. Correction of the trajectory of the projectile can be done vertically as well as horizontally, on a replica of long weapon as on a replica of handgun.

L'invention trouve des applications essentiellement dans le domaine des armes longues à ressort ou électriques et, notamment, des répliques d'armes longues telles que des fusils électriques. Elle s'applique, en particulier, aux répliques d'armes dont les projectiles sont des billes en matière plastique. Elle peut également équiper des répliques d'armes de poingThe invention finds applications essentially in the field of long spring or electric weapons and, in particular, replicas of long weapons such as electric rifles. It applies, in particular, to replica weapons whose projectiles are plastic balls. It can also equip replica handguns

Etat de la techniqueState of the art

Dans le domaine des répliques d'armes, des nombreux modèles d'armes à feux sont reproduits dans le but de réaliser des jouets, pour adultes et/ou pour enfants. Ces répliques d'armes sont généralement des armes qui projettent, à la place des balles ou des plombs des armes réelles, des projectiles en plastique, tels que des billes en plastique. Or, les répliques d'armes comportent généralement des défauts, provenant de la fabrication même de la réplique. Ces défauts, situés généralement dans le système de tir ou le canon, entraînent une déviation des projectiles lors de leur sortie de l'arme. Par exemple, en sortie de l'arme, les projectiles peuvent d'être déviés vers la droite ou au contraire vers la gauche, ou bien vers le haut ou vers le bas. Ces défauts sont quasiment inévitables et sont dus simplement aux tolérances de fabrication. Ils sont particulièrement gênant pour des répliques d'armes longues, de type fusil, dont la portée de tir est longue. On comprend, en effet, que plus la distance à parcourir par le projectile est longue, plus la déviation de trajectoire du projectile est prononcée.In the field of replica weapons, many models of firearms are reproduced for the purpose of making toys for adults and / or children. These replica weapons are usually weapons that project, instead of bullets or pellets real weapons, plastic projectiles, such as plastic balls. However, replica weapons generally have defects, from the manufacture of the replica itself. These defects, generally located in the firing system or the barrel, cause deflection of the projectiles when they exit the weapon. For example, at the exit of the weapon, the projectiles can be deflected to the right or on the contrary to the left, or upwards or downwards. These defects are almost inevitable and are simply due to manufacturing tolerances. They are particularly troublesome for replicas of long weapons, rifle type, whose range of fire is long. It is understood, in fact, that the longer the distance to be traveled by the projectile, the greater the trajectory deviation of the projectile is pronounced.

Actuellement, dans la plupart des répliques d'armes longues, aucune correction n'est apportée à la trajectoire des projectiles.Currently, in most replicas of long weapons, no correction is made to the trajectory of the projectiles.

Un système existe cependant pour corriger verticalement la trajectoire des projectiles en sortie du canon de la réplique d'arme. Ce système, appelé système HOP UP ®, consiste en un doigt en caoutchouc placé à l'intérieur du canon de l'arme, à l'entrée et à la verticale du centre du canon. Plus précisément, ce doigt en caoutchouc est situé sur l'axe vertical qui traverse le canon de l'arme en son centre, dans la partie supérieure du canon. Ce doigt en caoutchouc a un rôle de retenue et d'orientation du projectile. En effet, ce doigt en caoutchouc retient sensiblement le projectile, projeté par le système de tir, avant sa sortie du canon de l'arme. Le fait de retenir le projectile lors de sa sortie hors canon, donne au projectile un effet de rotation, dans sa trajectoire de sortie. Cet effet de rotation a pour conséquence de faire remonter le projectile, c'est-à-dire de modifier la trajectoire du projectile vers le haut. Toutefois, le propre poids du projectile compense la trajectoire volontairement montante du projectile, ce qui produit une trajectoire horizontale du projectile, un court instant après sa sortie du canon.A system exists, however, to vertically correct the trajectory of the projectiles at the exit of the barrel of the replica weapon. This system, called the HOP UP ® system, consists of a rubber finger placed inside the barrel of the weapon, at the entrance and vertical of the center of the barrel. More precisely, this rubber finger is located on the vertical axis which passes through the barrel of the weapon at its center, in the upper part of the barrel. This rubber finger has a role of restraint and orientation of the projectile. Indeed, this rubber finger substantially retains the projectile, projected by the firing system, before its exit from the barrel of the weapon. Holding the projectile out of the barrel gives the projectile a rotating effect in its exit trajectory. This effect of rotation has the effect of raising the projectile, that is to say, to change the trajectory of the projectile upwards. However, the projectile's own weight compensates for the voluntarily rising trajectory of the projectile, which produces a horizontal trajectory of the projectile, a short time after its exit from the gun.

Comme on le comprend à la lecture de cette explication, ce système HOP UP permet une correction de la trajectoire du projectile, uniquement verticale. Or, comme on l'a dit précédemment, les défauts de fabrication des répliques d'armes peuvent induire des défauts de trajectoire aussi bien verticaux qu'horizontaux.As understood when reading this explanation, this system HOP UP allows a correction of the trajectory of the projectile, only vertical. However, as mentioned above, defects in the manufacture of replica weapons can lead to both vertical and horizontal deflections of trajectory.

Exposé de l'inventionPresentation of the invention

L'invention a justement pour but de remédier aux inconvénients du système décrit précédemment. A cette fin, elle propose un dispositif pour corriger la trajectoire d'un projectile en sortie du canon d'une arme longue électrique, cette correction pouvant être verticale ou bien à la fois verticale et horizontale. Pour cela, le dispositif de l'invention consiste à placer deux doigts en caoutchouc situés symétriquement de part et d'autre de l'axe vertical passant par le centre du canon.The purpose of the invention is precisely to remedy the disadvantages of the system described above. To this end, it proposes a device for correcting the trajectory of a projectile at the exit of the barrel of a long electric weapon, this correction being vertical or both vertical and horizontal. For this, the device of the invention consists in placing two rubber fingers located symmetrically on either side of the vertical axis passing through the center of the barrel.

Plus précisément, l'invention concerne un dispositif de correction de la trajectoire d'un projectile en sortie d'un canon d'une réplique, comportant un premier doigt formant un premier bossage de retenue du projectile dans le canon,
caractérisé en ce qu'il comporte un second doigt formant un second bossage de retenue du projectile dans le canon, les premier et second doigts étant situés symétriquement de part et d'autre d'un axe vertical passant par le centre du canon.More specifically, the invention relates to a device for correcting the trajectory of a projectile at the exit of a gun of a replica, comprising a first finger forming a first projection boss of the projectile in the barrel,
characterized in that it comprises a second finger forming a second projection boss of the projectile in the barrel, the first and second fingers being located symmetrically on either side of a vertical axis passing through the center of the barrel.

Avantageusement, la hauteur des premier et second bossages dans le canon est réglable, permettant ainsi tous les réglages possibles sur l'effet donné à la bille afin d'optimiser la précision de tir.Advantageously, the height of the first and second bosses in the barrel is adjustable, thus allowing all possible settings on the effect given to the ball to optimize shooting accuracy.

Description détaillée de modes de réalisation de l'inventionDETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

La figure 1 représente une vue de face, en coupe, du canon d'une réplique d'arme longue électrique, par exemple une réplique d'un fusil. Cette réplique d'arme longue électrique, appelée plus simplement arme ou réplique d'arme, est munie du dispositif de correction de trajectoire de l'invention. Sur cette figure 1, le canon de l'arme est référencé 1. Il comporte une face intérieure 1 i et une face extérieure 1 e. Ce canon 1 est équipé, le long de sa face intérieure 1i d'un joint de canon 2. Ce joint de canon 2 est réalisé, classiquement, dans une matière élastique telle que du caoutchouc.Figure 1 shows a front view, in section, of the barrel of a replica long electric weapon, for example a replica of a rifle. This replica of long electric weapon, more simply called weapon or replica weapon, is provided with the trajectory correction device of the invention. In this figure 1, the barrel of the weapon is referenced 1. It has an inner face 1 i and an outer face 1 e. This barrel 1 is equipped, along its inner face 1i of a barrel seal 2. This barrel seal 2 is made, conventionally, in an elastic material such as rubber.

Un point C est représenté au centre du canon, qui montre le centre géométrique du canon par lequel passent l'axe vertical référencé XX ainsi que l'axe horizontal HH.A point C is represented in the center of the barrel, which shows the geometric center of the barrel through which the vertical axis referenced XX and the horizontal axis HH.

Conformément à l'invention, le canon 1 est muni d'un dispositif de correction de la trajectoire des projectiles. Ce dispositif comporte un premier doigt 3d (doigt droit) et un second doigt 3g (doigt gauche) qui forment, respectivement, à l'intérieur du canon 1, un premier bossage 6d et un second bossage 6g. Ces doigts 3d et 3g sont placés symétriquement de part et d'autre de l'axe vertical XX, au-dessus de l'axe horizontal HH. Dans l'exemple de la figure 1, les doigts 3d et 3g sont placés à un angle d'environ 40° par rapport à l'axe vertical XX.According to the invention, the barrel 1 is provided with a device for correcting the trajectory of the projectiles. This device comprises a first finger 3d (right finger) and a second finger 3g (left finger) which form, respectively, inside the barrel 1, a first boss 6d and a second boss 6g. These fingers 3d and 3g are placed symmetrically on either side of the vertical axis XX, above the horizontal axis HH. In the example of FIG. 1, the fingers 3d and 3g are placed at an angle of approximately 40 ° with respect to the vertical axis XX.

Les vis des doigts 3d et 3g peuvent être introduites à l'intérieur du canon en traversant le canon 1 lui-même. Elle peuvent aussi être introduites en traversant le support du canon et le canon lui-même. Dans ce dernier cas, cela permet de placer les molettes de réglage à proximité de la crosse de la réplique d'arme. Le tireur peut alors aisément régler les hauteurs de bossages tout en continuant de viser sa cible.The screws 3d and 3g fingers can be introduced inside the barrel through the barrel 1 itself. It can also be introduced by crossing the barrel holder and the barrel itself. In the latter case, this makes it possible to place the adjustment knobs near the butt of the replica weapon. The shooter can then easily adjust the heights of bosses while continuing to target his target.

Dans le mode de réalisation de la figure 1, chaque doigt 3d et 3g comporte une vis, respectivement, 4d et 4g qui s'enfonce dans le joint 2 du canon et forme, ainsi, par pression sur le joint, les bossages 6d et 6g, respectivement. Dans ce mode de réalisation, les vis 4d et 4g sont surmontées chacune d'une mollette, respectivement, 5d et 5g qui permet de régler la hauteur de la vis s'enfonçant dans le joint 2. Ainsi, en vissant plus ou moins chaque vis dans le canon 1, celle-ci s'enfonce plus ou moins dans le joint 2 créant un bossage plus ou moins important. Le système de réglage de la hauteur des bossages est donc rotatif.In the embodiment of FIG. 1, each finger 3d and 3g comprises a screw, respectively, 4d and 4g which is inserted into the seal 2 of the barrel and thus forms, by pressure on the seal, the bosses 6d and 6g , respectively. In this embodiment, the screws 4d and 4g are each surmounted by a wheel, respectively, 5d and 5g which allows to adjust the height of the screw sinking in the seal 2. Thus, by screwing more or less each screw in the barrel 1, it sinks more or less in the seal 2 creating a more or less prominent boss. The system for adjusting the height of the bosses is therefore rotatable.

En d'autres termes, le réglage de la hauteur de chaque vis s'enfonçant dans le joint 2 règle la hauteur de chaque bossage. Les bossages 6d et 6g peuvent donc avoir des hauteurs identiques ou, au contraire, des hauteurs différentes.In other words, adjusting the height of each screw sinking into the seal 2 adjusts the height of each boss. The bosses 6d and 6g may therefore have identical heights or, conversely, different heights.

Le rôle de chacun de ces bossages est de retenir sensiblement le projectile au moment où celui-ci est projeté hors du canon. Cette retenue permet de modifier la trajectoire du projectile en sortie du canon. Le fait d'avoir des hauteurs de bossages différentes permet de modifier la trajectoire horizontalement. Autrement dit, l'existence même des bossages permet de modifier la trajectoire des projectiles verticalement. Le réglage différentiel des hauteurs de bossages permet de modifier la trajectoire des projectiles horizontalement, c'est-à-dire vers la droite ou vers la gauche. En effet, lorsque le bossage a une petite hauteur cela diminue l'effet sur le projectile lors de son passage et, au contraire, lorsqu'il a une grande hauteur, cela augmente l'effet sur le projectile lors de son passage.The role of each of these bosses is to substantially retain the projectile when it is projected out of the barrel. This restraint makes it possible to modify the trajectory of the projectile at the exit of the barrel. The fact of having different heights of bosses makes it possible to modify the trajectory horizontally. In other words, the very existence of the bosses makes it possible to modify the trajectory of the projectiles vertically. The differential adjustment of the boss heights makes it possible to modify the trajectory of the projectiles horizontally, that is to say to the right or to the left. Indeed, when the boss has a small height it reduces the effect on the projectile during its passage and, on the contrary, when it has a great height, it increases the effect on the projectile during its passage.

On comprend que si les bossages 6d et 6g sont de hauteurs identiques, c'est-à-dire que si la mollette du doigt 3d et la mollette du doigt 3g sont réglées de façon identique, alors la trajectoire du projectile n'est pas modifiée horizontalement ; elle est corrigée uniquement dans le plan vertical. Par contre, si les bossages 6d et 6g ont des hauteurs différentes, cela influe sur la trajectoire du projectile dans le plan horizontal et dans le plan vertical.It is understood that if the bosses 6d and 6g are of identical heights, that is to say that if the finger wheel 3d and finger wheel 3g are set identically, then the trajectory of the projectile is not changed horizontally; it is corrected only in the vertical plane. On the other hand, if the bosses 6d and 6g have different heights, this affects the trajectory of the projectile in the horizontal plane and in the vertical plane.

En particulier, si le bossage gauche 6g est plus fort que la bossage droit 6d, alors le tir est orienté vers la gauche. Au contraire, si le bossage droit 6d est plus fort que le bossage gauche 6g, alors le tir est orienté vers la droite.In particular, if the left boss 6g is stronger than the right boss 6d, then the shot is oriented to the left. On the contrary, if the right boss 6d is stronger than the left boss 6g, then the shot is oriented to the right.

Un exemple d'orientation de tirs est représenté sur la figure 2. Plus précisément, la figure 2 représente une cible sur laquelle trois tirs de projectiles ont été réalisés.An example of firing orientation is shown in FIG. 2. More precisely, FIG. 2 represents a target on which three shots have been fired.

Le résultat du premier tir T1 montre que le projectile était corrigé uniquement verticalement. Les bossages droit 6d et gauche 6g étaient donc identiques.The result of the first shot T1 shows that the projectile was corrected only vertically. The right 6d and left 6g bosses were identical.

Le résultat du second tir T2 est orienté à droite de l'axe vertical XX. Cela montre que la hauteur du bossage droit 6d était plus grande que celle du bossage gauche 6g.The result of the second shot T2 is oriented to the right of the vertical axis XX. This shows that the height of the right boss 6d was greater than that of the left boss 6g.

Au contraire, le résultat du troisième tir T3 est situé à gauche de l'axe vertical XX. Cela montre que le bossage gauche 6g était plus important que le bossage droit 6d.On the contrary, the result of the third shot T3 is located to the left of the vertical axis XX. This shows that the left boss 6g was larger than the right boss 6d.

Cette figure 2 montre donc que la trajectoire d'un projectile peut être modifiée, dans le plan horizontal en plus du plan vertical, en faisant varier la hauteur des bossages 6d et 6g. On comprend ainsi que la correction de la trajectoire des projectiles dans l'ensemble de l'espace permet de corriger à peu près tous les défauts de trajectoire d'une réplique d'arme.This figure 2 thus shows that the trajectory of a projectile can be modified, in the horizontal plane in addition to the vertical plane, by varying the height of the bosses 6d and 6g. It is thus understood that the correction of the trajectory of the projectiles in the whole of the space makes it possible to correct almost all the defects of trajectory of a replica of weapon.

Sur la figure 3A, on a représenté une vue de coté, en coupe, d'un deuxième mode de réalisation du dispositif de l'invention. Dans ce mode de réalisation, le doigt de réglage est référencé 8. Ce doigt 8 comporte un téton 9 en matière élastique, par exemple en caoutchouc, monté sur une lame élastique 10, par exemple en métal. Le téton 9 est fixé à l'une des extrémités de la lame élastique 10 par n'importe quel moyen de fixation, par exemple par collage ou par perçage. La lame élastique 10 est fixée sur une certaine longueur, par exemple sur la moitié de sa longueur, à une tige de commande 11, par exemple en métal.FIG. 3A shows a side view, in section, of a second embodiment of the device of the invention. In this embodiment, the adjustment finger is referenced 8. This finger 8 comprises a pin 9 of elastic material, for example rubber, mounted on an elastic blade 10, for example metal. The pin 9 is attached to one end of the elastic blade 10 by any means of attachment, for example by gluing or drilling. The elastic blade 10 is fixed over a certain length, for example over half of its length, to a control rod 11, for example metal.

Un orifice 13 est réalisé dans le canon 1 pour permettre le passage du téton 9. Le téton 9 est donc maintenu dans une position choisie par le tireur, dans l'orifice 13. Le téton 9 forme ainsi un bossage à l'intérieur du canon de l'arme. La hauteur de ce bossage est commandée par la tige de commande 11 associée à la lame élastique 10. Plus précisément, la lame élastique 10 maintient le téton 9 plus ou moins profondément dans l'orifice 13. Pour cela, la lame élastique 10 est mise en extension par la tige de commande 11 sur laquelle elle est fixée. Ainsi, plus la tige de commande 11 est tirée vers le tireur, plus la lame élastique 10 est en extension et moins le téton 9 est introduit profondément dans l'orifice 13, donc moins le bossage est fort. Au contraire, plus la tige de commande est poussée vers le support de canon 7, plus la lame élastique 10 est détendue et plus le téton 9 entre profondément dans l'orifice 13 et donc plus le bossage est important. Ainsi, lorsque la tige de commande 11 est poussée au maximum vers le canon 1, alors la lame élastique 10 se place contre la surface extérieure du canon 1, ce qui a pour conséquence de faire entrer le téton 9 à l'intérieur du canon 1 de façon proéminente, ce qui créer un bossage d'une hauteur maximum sans pour autant risquer un blocage d'une bille un peu grosse , car la souplesse de la lame élastique permettra quand même son éjection ! Par contre, lorsque la tige de commande 11 est tirée au maximum vers le tireur, alors la lame élastique 10 est en extension maximum (comme montré sur la figure 3A), ce qui a pour conséquence de relever le téton au maximum dans l'orifice 13, ne créant aucun bossage.An orifice 13 is made in the barrel 1 to allow the passage of the stud 9. The stud 9 is thus maintained in a position chosen by the shooter in the orifice 13. The stud 9 thus forms a boss inside the barrel of the weapon. The height of this boss is controlled by the control rod 11 associated with the elastic blade 10. More specifically, the elastic blade 10 maintains the nipple 9 more or less deeply in the orifice 13. For this, the elastic blade 10 is extended by the control rod 11 on which it is fixed. Thus, the more the control rod 11 is pulled towards the shooter, the more the elastic blade 10 is in extension and the less the pin 9 is introduced deep into the orifice 13, so less the boss is strong. On the contrary, the more the control rod is pushed towards the barrel holder 7, the more the elastic blade 10 is relaxed and the more the pin 9 enters deeply into the orifice 13 and therefore the larger the boss is important. Thus, when the control rod 11 is pushed to the maximum towards the barrel 1, then the elastic blade 10 is placed against the outer surface of the barrel 1, which has the effect of bringing the pin 9 inside the barrel 1 prominently, which creates a boss of a maximum height without risk of blocking a ball a little big, because the flexibility of the elastic blade will still eject! On the other hand, when the control rod 11 is pulled as far as possible towards the shooter, then the elastic blade 10 is in maximum extension (as shown in FIG. 3A), which has the consequence of raising the pin as far as possible in the orifice 13, creating no boss.

Pour faciliter cette manipulation de tirage ou de poussée de la tige de commande 11, cette dernière peut comporter une manette 11, qui peut être, par exemple, le prolongement de la tige de commande pliée selon un angle de 90° par rapport à l'axe horizontal HH. Dans ce cas, comme montré sur la figure 3B, cette manette 12 traverse un orifice oblong 15 réalisé dans la carcasse 14 de l'arme.To facilitate this manipulation of pulling or pushing of the control rod 11, the latter may comprise a lever 11, which may be, for example, the extension of the control rod bent at an angle of 90 ° to the horizontal axis HH. In this case, as shown in FIG. 3B, this lever 12 passes through an oblong orifice 15 made in the carcass 14 of the weapon.

En tirant ou en poussant plus ou moins cette manette 12, le tireur agit directement sur la hauteur du bossage formée par le téton 9. Ce mode de réalisation permet d'obtenir un système de réglage des hauteurs de bossages linéaire. Un tel réglage linéaire a l'avantage d'être plus facile à doser pour le tireur. En effet, la vision de la manette 12 dans le trou oblong 15 permet au tireur de visualiser le niveau du bossage, c'est-à-dire si le bossage est nul, faible, moyen, fort, maximum et tous les niveaux de bossages intermédiaires.By pulling or pushing this lever 12 more or less, the shooter acts directly on the height of the boss formed by the pin 9. This embodiment makes it possible to obtain a system for adjusting the linear boss heights. Such a linear adjustment has the advantage of being easier to meter for the shooter. Indeed, the vision of the lever 12 in the oblong hole 15 allows the shooter to view the level of the boss, that is to say if the boss is zero, low, medium, strong, maximum and all bosses levels intermediate.

Les figures 3A et 3B montrent un seul bossage et un seul système de réglage de la hauteur de ce bossage. On comprendra bien sûr que, comme pour le premier mode de réalisation (montré sur la figure 2), le dispositif de correction de trajectoire selon ce deuxième mode de réalisation comporte également deux bossages symétriques, la hauteur de chaque bossage étant est réglée par un système de commande (tige de commande, lame élastique, etc.) indépendant.Figures 3A and 3B show a single boss and a single system for adjusting the height of this boss. It will of course be understood that, as for the first embodiment (shown in FIG. 2), the device for trajectory correction according to this second embodiment also comprises two symmetrical bosses, the height of each boss being is set by a control system (control rod, elastic blade, etc.) independent.

Quel que soit le mode de réalisation choisi, le dispositif de correction de la trajectoire est placé juste après l'endroit d'où est projeté le projectile vers l'extérieur, à l'entrée du canon. Dans le premier mode de réalisation, les systèmes de réglage des bossages sont situés, en extérieur d'arme, à peu près à cet endroit d'où le projectile est projeté. Dans le second mode de réalisation, les systèmes de réglage des bossages ont l'avantage de pouvoir être déportés, c'est-à-dire placés à un endroit de l'arme choisi, par exemple proche du tireur.Whatever the embodiment chosen, the trajectory correction device is placed just after the place where the projectile is projected outward, at the entrance of the barrel. In the first embodiment, the adjustment systems of the bosses are located, outside weapon, approximately at this point where the projectile is projected. In the second embodiment, the adjustment systems bosses have the advantage of being deported, that is to say placed at a location of the chosen weapon, for example close to the shooter.

Dans une variante de l'invention, le dispositif de correction de trajectoire peut ne pas être réglable. Il peut alors équiper des répliques d'armes économiques. Dans ce cas, le dispositif de correction comporte deux bossages situés sur la partie supérieure du canon, de part et d'autre de l'axe XX. Ces deux bossages 6d et 6g sont identiques à ceux représentés sur la figure 1, excepté que leur hauteur n'est pas réglable. Les bossages sont alors réalisés par des demi sphères en matière caoutchouc formées sur la face intérieure du canon 1. Dans cette variante, lors de la prise d'effet de rotation, la bille est mieux calée que dans le cas connu où un seul bossage retient la bille, qui peut alors se décaler légèrement à gauche ou à droite de l'axe de tir. Ce dispositif permet ainsi de réduire la dispersion du tir, ce qui fournit un meilleur groupement des tirs lors d'une série de tirs.In a variant of the invention, the trajectory correction device may not be adjustable. He can then equip replicas of economic weapons. In this case, the correction device comprises two bosses located on the upper part of the barrel, on either side of the axis XX. These two bosses 6d and 6g are identical to those shown in Figure 1, except that their height is not adjustable. The bosses are then made by half-spheres of rubber material formed on the inner face of the barrel 1. In this variant, when taking effect of rotation, the ball is better wedged than in the known case where a single boss holds the ball, which can then shift slightly to the left or right of the axis of fire. This device thus reduces the dispersion of the shot, which provides a better grouping of shots in a series of shots.

Dans une variante non-revendiquée, l'emplacement des bossages 6d et 6g sur la face intérieure du canon 1 est réglable. Cette variante est représentée sur la figure 4. Dans cette variante, les bossages sont identiques à ceux de la variante précédente et le dispositif de correction comporte une molette 16 fixée sur le canon 1, à égale distance des deux bossages 6d et 6g. Le canon (ou la partie du canon comportant les deux bossages) étant libre en rotation, la molette 16 permet de faire pivoter le canon 1 dans le support de canon 7 et, par conséquent, de déplacer les bossages 6d et 6g par rapport à l'axe XX. Cette rotation du canon, totale ou partielle, à gauche ou à droite de l'axe XX, permet de corriger le tir à gauche ou à droite de l'axe XX. Autrement dit, cette rotation du canon permet de corriger la trajectoire de la bille horizontalement.In an unclaimed variant, the location of the bosses 6d and 6g on the inner face of the barrel 1 is adjustable. This variant is shown in Figure 4. In this variant, the bosses are identical to those of the previous variant and the correction device comprises a wheel 16 fixed on the barrel 1, equidistant from the two bosses 6d and 6g. The barrel (or part of the barrel with the two bosses) being free to rotate, the knob 16 makes it possible to rotate the barrel 1 in the barrel holder 7 and, consequently, to move the bosses 6d and 6g with respect to the barrel. XX axis. This rotation of the gun, total or partial, left or right of the axis XX, makes it possible to correct the firing on the left or on the right of the axis XX. In other words, this rotation of the barrel makes it possible to correct the trajectory of the ball horizontally.
