Abstract
L'invention concerne un manchon de convergence de chokes amovibles externes de fusil de chasse superpose ou juxtapose. il est caractérisé par la confection d'un manchon perce de deux alésages, un de diamètre identique au diamètre du choke supérieur ou latéral droite ou gauche, un de diamètre supérieur au diamètre du choke inferieur ou latéral droite ou gauche. Ce dernier est équipé de moyen mécanique (vis de pression, excentrique, clavettes, etc.) permettant-de faire varier l'axe de tir par rapport a l'autre choke immobilise dans son alésage. Le déplacement du choke dans tous les plans permet de modifier le tir par rapport a l'autre canon et permet de faire converger les tirs des deux canons.The invention relates to a converging sleeve of external removable chokes of shotgun superimposed or juxtapose. it is characterized by the manufacture of a sleeve bores of two bores, one of diameter identical to the diameter of the upper choke or lateral right or left, one of diameter greater than the diameter of the lower choke or lateral right or left. The latter is equipped with mechanical means (pressure screw, eccentric, keys, etc.) for varying the firing axis relative to the other choke immobilizes in its bore. The movement of the choke in all the planes makes it possible to modify the shot compared to the other gun and makes it possible to converge the shots of the two guns.
Description
1 La présente invention concerne un manchon de convergence de chokes amovibles externes de canon de fusil de chasse. Les canons de fusil de chasse (figure 1/4, repère 1 et 2) superposés ou juxtaposés actuels sont équipés de chokes amovibles soit internes, soit externes (figure 1/4, repère 3 et 4).The present invention relates to a converging sleeve of external removable chokes of shotgun barrel. The shotgun barrels (figure 1/4, mark 1 and 2), stacked or juxtaposed today are equipped with removable chokes either internal or external (Figure 1/4, mark 3 and 4).
Ceux-ci sont vissés à l'extrémité des canons dans l'axe de ceux-ci et dirige le tir dans l'axe des canons. Le dispositif selon l'invention permet de modifier l'axe de sortie d'un canon part rapport à l'autre canon en modifiant l'axe d'un choke amovible externe par rapport au choke amovible externe de l'autre canon et de ce fait, de régler la convergence du tir des deux canons (figure 2/4 repère 5).These are screwed to the end of the guns in the axis of these and directs the shooting in the axis of the guns. The device according to the invention makes it possible to modify the output axis of a gun relative to the other gun by modifying the axis of an external removable choke relative to the external removable choke of the other gun and this done, to adjust the convergence of the firing of the two guns (figure 2/4 reference 5).
Ce dispositif est constitué d'un manchon percé de deux alésages débouchant dans lesquels s'insèrent les chokes amovibles externes des canons du fusil. Un des alésages est percé au diamètre externe du choke amovible externe (figure 3/4, repère 6), le deuxième alésage est perce à un diamètre supérieur au diamètre externe du choke amovible externe (figure 3/4, repère 7). L'alésage percé à un diamètre supérieur au choke amovible externe comporte, sur sa partie arrière, deux vis antagonistes immobilisant le manchon sur le choke amovible externe pur lui interdire tous mouvements soit axial, soit latéral (figure 2/4, repère 8). Ce deuxième alésage comporte à son extrémité des systèmes mécaniques (vis, figure 2/4, repère 9, figure 4/4 repère 9), ou excentriques, ou toute autre moyen de pression permettant de faire varier dans le plan horizontal, et ou, vertical la position du choke amovible externe (figure 4/4, repère 4) par rapport à l'autre choke emmanché sans jeu dans son alésage (figure 4/4, repère 3). Le résultat est la modification du point d'impact au tir du choke réglable par rapport au choke non réglable. La figure 1/4 représente les canons de fusil de chasse montés avec des chokes amovibles 25 externes sans le manchon de réglage de convergence. La figure 2/4 représente les canons de fusil de chasse manchon installé. La figure 3/4 représente, en coupe, le manchon de convergence installe sur les canons de fusil de chasse équipés des chokes amovibles externes. La figure 4/4 représente le manchon de convergence de face installé sur le canon de fusil 30 de chasse.This device consists of a sleeve pierced by two bores opening into which the external removable chokes of the guns of the rifle are inserted. One of the bores is drilled to the external diameter of the outer removable choke (Figure 3/4, item 6), the second bore is drilled to a diameter greater than the outer diameter of the external removable choke (Figure 3/4, item 7). The bore drilled to a diameter greater than the external removable choke comprises, on its rear part, two opposing screws immobilizing the sleeve on the external removable choke to prohibit any movement is axial or lateral (Figure 2/4, reference 8). This second bore comprises at its end mechanical systems (screw, FIG. 2/4, reference 9, FIG. 4/4 reference 9), or eccentric, or any other pressure means making it possible to vary in the horizontal plane, and or, vertical position of the external removable choke (Figure 4/4, mark 4) relative to the other choke fitted without play in its bore (Figure 4/4, mark 3). The result is the modification of the shooting impact point of the adjustable choke compared to the non-adjustable choke. Figure 1/4 shows the shotgun barrels mounted with external removable chokes without the convergence adjustment sleeve. Figure 2/4 shows the shotgun barrels sleeve installed. Figure 3/4 shows, in section, the convergence sleeve installed on the shotgun barrels equipped with external removable chokes. Figure 4/4 shows the face mating sleeve installed on the shotgun barrel.
