Abstract
Description
La présente invention concerne les munitions destinées à être tirées parThe present invention relates to ammunition intended to be fired by
des armes à feu de petit, moyen et gros calibre à canon lisse et particulièrement un nouveau type de projectile profilé monobloc notamment pour armes de chasse présentant une efficacité améliorée sur cibles molles avec destruction small, medium and large caliber firearms with a smooth barrel and particularly a new type of profiled projectile monobloc including hunting weapons with improved efficiency on soft targets with destruction
des parties dures de ladite cible.hard parts of said target.
Certains projectiles transpercent le gibier sans le stopper, d'autres projectiles se fragmentent à l'impact, se séparent ou se pétalisent et ne champignonnent que sur les parties dures. Some projectiles pierce the game without stopping it, other projectiles fragment on impact, separate or petalize and only mush on the hard parts.
Le projectile selon l'invention permet de remédier à ces inconvénients. De plus, il peut être réalisé en un matériau sans plomb, à partir de barres profilées. The projectile according to the invention overcomes these disadvantages. In addition, it can be made of a material without lead, from profiled bars.
L'invention a pour objet un dispositif monobloc qui permet d'obtenir une réduction de la surface portante dans le canon de l'arme tout en assurant une augmentation de la surface atteinte dans la cible sans fragmentation ni séparation du projectile. The invention relates to a one-piece device that allows to obtain a reduction of the bearing surface in the barrel of the weapon while ensuring an increase in the area reached in the target without fragmentation or separation of the projectile.
Le dispositif de l'invention est essentiellement constitué par un projectile caractérisé par le fait qu'il comporte un corps monobloc constitué en un matériau propre à coopérer avec le canon de l'arme par des empennes au nombre de 4 qui assurent également la stabilité dudit projectile pendant sa trajectoire, des arêtes fuyantes font le lien continu entre la partie avant du canal axial ouvert de part en part et le diamètre extérieur des empennes. L'invention pourra de toute façon être bien comprise à l'aide du complément de description qui suit, ainsi que des dessins ci-annexés, lesquels compléments et dessins sont relatifs à des modes de réalisation préférés de l'invention et ne comportent bien entendu aucun caractère limitatif. The device of the invention consists essentially of a projectile characterized in that it comprises a one-piece body made of a material capable of cooperating with the barrel of the weapon by empires of four in number which also ensure the stability of said projectile during its trajectory, elusive edges make the continuous link between the front part of the open axial channel and the outside diameter of the empennas. The invention may in any case be well understood with the aid of the additional description which follows, as well as the attached drawings, which complements and drawings relate to preferred embodiments of the invention and do not include of course no limiting character.
La figure 1 représente en coupe, le dispositif selon l'invention. Figure 1 shows in section, the device according to the invention.
La figure 2 représente en perspective la section en coupe selon A,A' de la figure 1 du dispositif. Figure 2 shows in perspective the cross-section along A, A 'of Figure 1 of the device.
En référence à ces dessins, le dispositif comporte un corps monobloc (1), des empennes au nombre de quatre (2,3,4,5),des arêtes fuyantes au nombre de quatre (6,7,8,9) un rayon (10) fait la continuité entre l'empenne (2) et l'empenne (3), un rayon (11) fait la continuité entre l'empenne (3) et l'empenne (4) , un rayon (12) fait la continuité entre l'empenne (4) et l'empenne (5) un rayon (13) fait la continuité entre l'empenne (5) et l'empenne (2), un canal axial (14) de faible _'2_ conicité (15) ouvert de part en part est aménagé pour recevoir un insert (16) de faible conicité (17) complémentaire à la conicité (15) du canal axial (14). With reference to these drawings, the device comprises a one-piece body (1), empires four in number (2,3,4,5), fleeing edges four in number (6,7,8,9) a radius (10) makes the continuity between the pile (2) and the pile (3), a radius (11) makes the continuity between the pile (3) and the pile (4), a radius (12) makes the continuity between the pile (4) and the pile (5) a radius (13) makes the continuity between the pile (5) and the pile (2), an axial channel (14) of low _'2_ conicity (15) open from side to side is arranged to receive an insert (16) of small conicity (17) complementary to the conicity (15) of the axial channel (14).
Ledit insert (16) comporte des canaux ouverts (18,19,20,21) qui se terminent sur des faces angulaires (22,23) les profilés (24,25,26,27) coopèrent avec le canon de l'arme et déterminent le calibre du projectile selon l'invention. Said insert (16) has open channels (18,19,20,21) which terminate on angular faces (22,23). The profiles (24,25,26,27) cooperate with the barrel of the weapon and determine the caliber of the projectile according to the invention.
La fonction de l'insert (16) est de contrôler l'écoulement de l'air par ses canaux ouverts (18,19,20,21) à l'intérieur du canal axial (14) pendant le vol du projectile et de retenir des matières organiques lors de l'atteinte de la cible sur la face angulaire (22) les conicités complémentaires (15,17) permettent la solidari- lo sation de l'insert (16) dans le canal axial (14) et d'être solidaires par un assemblage auto serrant du corps monobloc (1), l'étanchéité des gaz de propulsion dans le canon de l'arme est assurée par une bourre de chasse non représentée qui prend appui sur la face arrière (28) du corps monobloc (1) et des empennes (2,3,4,5). The function of the insert (16) is to control the flow of air through its open channels (18,19,20,21) within the axial channel (14) during the flight of the projectile and to retain organic materials when reaching the target on the angular face (22) the complementary conicities (15,17) allow the solidari- lation of the insert (16) in the axial channel (14) and to be secured by a self-tightening assembly of the one-piece body (1), the sealing of the propulsion gases in the barrel of the weapon is ensured by an unrepresented flock which bears on the rear face (28) of the one-piece body ( 1) and empires (2,3,4,5).
