Description

La présente invention concerne les munitions de chasse au gr@s @@ constituées par une balle profilée symétrique.The present invention relates to gr @ s @@ hunting ammunition constituted by a symmetrical profiled bullet.

Dans les dispositifs connus de ce genre, on trouve des balles de forme ogivale trop légères qui font expansion sur le moindre obstaole, ou des balles trop lourdes qui transpercent l'animal de part en part sans faire expansion, le trou de sortie étant réduit an diamètre de la balle. Ce genre de balle mutile le gibier sans l'arrêter. In known devices of this kind, there are balls of too light ogival shape which expand on the smallest obstaole, or too heavy balls which pierce the animal right through without expanding, the exit hole being reduced an diameter of the ball. This kind of bullet mutilates the game without stopping it.

La balle profilée symétrique selon l'invention permet d'éviter ces inconvénients.  The symmetrical profiled ball according to the invention makes it possible to avoid these drawbacks.

Le but recherché, est qu'il faut trouver un projectile qui ait une pénétration suffisante pour atteindre les organes vitaux de l'animal et qui assure an même temps une expansion sous l'effet de choc capable de provoquer la blessure qui l'arrêtera. La balle selon l'invention permet d'atteindre ce but. The aim is to find a projectile which has sufficient penetration to reach the animal's vital organs and which at the same time ensures an expansion under the shock effect capable of causing the injury which will stop it. The ball according to the invention achieves this goal.

La présente invention se rapporte à une balle profilée symétrique, comportant un guide avant et un guide arrière identiques, servant de point de frottement dans le canon de l'arme et créant un offet de choc et l'expansion. Ces guides sont rendus solidaires entre eux par un no Fan de forme o8nique inversées. The present invention relates to a symmetrical profiled bullet, comprising an identical front guide and a rear guide, serving as a point of friction in the barrel of the weapon and creating a shock and expansion shock. These guides are made integral with each other by a no Fan of inverted shape.

D'autres particularités et avantages de l'invention apparaîtront an cours de la description qui va suivre, laquelle faite on référence aux dessins annexés, donnés à titre d'exemple non limitatif, fera bien comprendre comment la présente invention peut être mise en pratique. Other features and advantages of the invention will become apparent from the description which follows, which refers to the accompanying drawings, given by way of non-limiting example, will make it clear how the present invention can be put into practice.

La figure 1 est une vue de face de l'ensemble de la balle. Figure 1 is a front view of the entire ball.

La figure 2 est une vue do face on coupe du guide avant.  Figure 2 is a front view in section of the front guide.

La figure 3 est une vue de face en coupe du guide arrière. Figure 3 is a front sectional view of the rear guide.

La figure 4 est une vue de face du noyau. Figure 4 is a front view of the core.

La description qui va suivre se rapporte à une balle profilée symé- trique. La figure 1 est une vue d'ensemble de la balle, comme on le voit à l'examen de cette figure, la balle est composée de trois parties le guide 1, le guide 2, et le noyau 3. The description which follows relates to a symmetrical profiled ball. FIG. 1 is an overall view of the ball, as seen on examining this figure, the ball is made up of three parts, the guide 1, the guide 2, and the core 3.

Le guide 1 est formé par l'arc de cercle 4 de rayon R1 égal au dia- mètre D1 qui détermine le calibre de la balle par l'arc de cercle 5 de
rayon R2 permettant de tangeanter le diamètre D1 de l'arc 4 et le diamètre D2 inférieur à D1, et par un évidement 6 de forme cônique 7 se terminant an pointe 8.Guide 1 is formed by the circular arc 4 of radius R1 equal to the diameter D1 which determines the caliber of the bullet by the circular arc 5 of
radius R2 allowing the diameter D1 of the arc 4 and the diameter D2 to be less than D1, and by a recess 6 of conical shape 7 ending at the tip 8.

Le guide 2 est identique an guide 1, il est formé par l'arc 9 de rayon R3 égal au diamètre D3 qui est défini par le calibre de la balle, par l'arc 10 de rayon R4 permettant de tangeanter le diamètre de de 1' arc 9 et le diamètre D4 inférieur à D3 et égal à D2, et par un évidement 11 de forme cônique 12 se terminant en pointe 13.  The guide 2 is identical to guide 1, it is formed by the arc 9 of radius R3 equal to the diameter D3 which is defined by the caliber of the bullet, by the arc 10 of radius R4 making it possible to pitch the diameter of by 1 arc 9 and the diameter D4 less than D3 and equal to D2, and by a recess 11 of conical shape 12 ending in point 13.

Le noyau 3 est formé par l'élément mâle du premier cône Morse 14 se
terminant en pointe 15 et par l'élément mâle d'un deuxième cône Morse 16 se terminant en pointe 17. Il est connu que l'angle α d'un cône
Morse permet un serrage parfait.The core 3 is formed by the male element of the first Morse cone 14
ending in point 15 and with the male element of a second Morse cone 16 ending in point 17. It is known that the angle α of a cone
Morse allows perfect tightening.

Les cônes Morse 14 et 16 permettront après asssemblage serré de rendre solidaires entre es le guide 1, le guide 2 et le noyau 3. The Morse cones 14 and 16 will allow after tight assembly to make integral between the guide 1, the guide 2 and the core 3.

La figure 2 indique le guide 1 en vue de face en coupe, comme le montre cette figure l'arc 4 et l'arc 5 se tangeantent en D1 qui est le premier point de frottement de la balle dans le oanon de l'arme, et qui offre le moins de résistance, donc utilise le moins d'énergie. Il est connu en balistique interne que tous frottements créent un échauffement dans le canon donc une perte de l'énergie initiale. Le profilé déterminé par l'arc 4 et l'arc 5 permet en balistique extérieure d'obtenir un CX réduit, ce qui améliore la précision de la balle et sa vitesse ce qui se traduit par un gain de l'énergie cinétique. L'évidement 6 de forme cônique 7 se terminant en pointe 8 reçoit l'élément mâle du cône Morse 14 ce qui donne unexoellent assemblage serré et parfaitement concentrique. FIG. 2 indicates the guide 1 in front view in section, as shown in this figure the arc 4 and the arc 5 are tangent in D1 which is the first point of friction of the bullet in the oanon of the weapon, and which offers the least resistance, therefore uses the least energy. It is known in internal ballistics that all friction creates a heating in the barrel therefore a loss of the initial energy. The profile determined by the arc 4 and the arc 5 allows in external ballistics to obtain a reduced CX, which improves the precision of the ball and its speed which results in a gain of kinetic energy. The recess 6 of conical shape 7 ending in point 8 receives the male element of the Morse cone 14 which gives unexoellent tight assembly and perfectly concentric.

La figure 3 Indique le guide 2 en vue de face de coupe, comme le montre cette figure, le guide 2 est identique au guide 1 de la figure 2, lais il est sasemblé sur l'élement mâle du oNe Morse 16 de la figure 1 en sens inverse du guide 1. L'avantage de ce procédé selon l'
invention est d'obtenir le deuxième point de frottement D3 dans le
canon de l'arme l'arc 10 a un rayon R4 égal à R2 ce qui permet à D4 d'être égal à D2 et de former après assemblage sur le cône Morse 16 avec l'évidement 11 de forme cônique 12 se terminant en pointe 13 un seul arc de rayon R4 R2. L'arc 9 permet un meilleur écoulement de l' air et réduit il tourbillons de plus il permet d'sugmenter la surfa- ce d'appui des gases en pression.Figure 3 Indicates guide 2 in sectional view, as shown in this figure, guide 2 is identical to guide 1 in figure 2, but it is assembled on the male element of the Morse oNe 16 of figure 1 in reverse of Guide 1. The advantage of this process according to
invention is to get the second point of friction D3 in the
barrel of the weapon the bow 10 has a radius R4 equal to R2 which allows D4 to be equal to D2 and to form after assembly on the Morse cone 16 with the recess 11 of conical shape 12 ending in a point 13 a single arc of radius R4 R2. The arc 9 allows a better flow of air and reduces it swirls more it allows to increase the support surface of gases under pressure.

La figure 4 indique ai vue de face le noyau 3 avec ses cônes Morse opposés 14 - 16 de diamètre 18 commun se terminant en pointe 15 - 17. Figure 4 shows the front view of the core 3 with its opposite Morse cones 14 - 16 of diameter 18 common ending in point 15 - 17.

Un tel dispositif selon l 'invention permet d'adapter des guides 1 et 2 identiques sur le noyan 3 ce qui réduit le ooat de fabrication; de plus il permet d'obtenir un centre de gravite parfait d'écoulant d'éléments symétriques et un auto-serrage de l'ensemble à l'explosion de la pondre dans l'étui. A la pression des gazes d'explosion sur l' arc 9 le guide 2 se serre sur l'élément mâle du cône Morse 16, l'élément mâle du cône Morse 14 se serre également dans l'évidement femelle 7 du fait de l'inertie du guide 1. Le noyau 3, le vide 2, et le guide 1, sont donc solidaires entre eux. La balle profilée symétrique selon l'invention est concentrique et son centre de gravité est équilibré. Such a device according to the invention makes it possible to adapt identical guides 1 and 2 on the core 3 which reduces the manufacturing ooat; moreover it makes it possible to obtain a perfect center of gravity flowing from symmetrical elements and a self-tightening of the assembly at the explosion of laying it in the case. At the pressure of the explosion gases on the arc 9 the guide 2 is tightened on the male element of the Morse cone 16, the male element of the Morse cone 14 is also tightened in the female recess 7 due to the inertia of the guide 1. The core 3, the vacuum 2, and the guide 1, are therefore interdependent. The symmetrical profiled ball according to the invention is concentric and its center of gravity is balanced.

Les guides 1 et 2 sont réalisés en matière tendre pour éviter l'u
sure des canons.Guides 1 and 2 are made of soft material to prevent u
on cannons.

Une des applications particulièrement intéressante de l'invention peut-être en dehors de la chasse an gros gibier, le tir sportif et
d'entrainement. One of the particularly interesting applications of the invention may be apart from big game hunting, sport shooting and
of training.
