Abstract
Description
La présente invention vise une munition d'entraînement. The present invention relates to a drive munition.
L'un des buts de l'invention est de réaliser une munition d'entraînement plus particulièrement pour armes légères et notamment des armes de poing dont le projectile soit allégé de manière qu'une telle munition puisse être utilisée dans des locaux autres que des stands de tir. One of the aims of the invention is to produce a training ammunition more particularly for small arms and in particular handguns whose projectile is lightened so that such ammunition can be used in premises other than stands shooting.
La munition, selon l'invention, est du type comprenant un étui avec un culot pourvu d'une amorce et destiné à contenir de la poudre et une balle sertie à l'em- bouchure de l'étui, et est caractérisée en ce que la balle est réalisée en une matière souple et élastique et présente à son extrémité arrière une jupe. The ammunition according to the invention is of the type comprising a case with a base provided with a primer and intended to contain powder and a bullet set at the mouth of the case, and is characterized in that the ball is made of a flexible and elastic material and has a skirt at its rear end.
Grâce à cette disposition, lors du départ du coup, la jupe tend à s'expanser et son bord latéral vient épouser les rayures du canon ce qui permet d'avoir un projectile qui pour des courtes distances est très performant. Thanks to this arrangement, at the start of the shot, the skirt tends to expand and its lateral edge comes to marry the scratches of the barrel which allows to have a projectile which for short distances is very efficient.
De préférence, l'extrémité avant de la balle est arrondie et raccordée à la paroi latérale par une partie tronconique. Preferably, the front end of the bale is rounded and connected to the side wall by a frustoconical part.
Suivant encore une autre caractéristique, l'ex trémité arrière de la balle est légèrement évasée. According to yet another characteristic, the rear end of the ball is slightly flared.
Enfin, suivant une dernière caractéristique, la balle à son extrémité arrière comporte une cavité pour former la jupe, cette cavité affectant la forme d'un tronc de cône. Ainsi on augmente la souplesse du bord libre de la jupe. Finally, according to a last characteristic, the ball at its rear end has a cavity to form the skirt, this cavity affecting the shape of a truncated cone. This increases the flexibility of the free edge of the skirt.
L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple eezlement et représenté aux dessins annexés, dans lesquels
Figure 1 est une vue en coupe d'une munition, selon l'invention.The invention will now be described in more detail with reference to a particular embodiment given by way of example and shown in the accompanying drawings, in which
Figure 1 is a sectional view of ammunition, according to the invention.
Figure 2 est une vue en coupe à plus grande échelle de la balle. Figure 2 is an enlarged sectional view of the ball.
La munition représentée aux figures comprend un étui 1 destiné à contenir de la poudre, ledit étui comportant un culot 2 pourvu d'une amorce 3. The ammunition shown in the figures comprises a case 1 intended to contain powder, said case comprising a base 2 provided with a primer 3.
L'extrémité libre de l'étui 1 est sertie sur une balle 4. The free end of the case 1 is crimped onto a ball 4.
La balle 4 est représentée plus en détail à la figure- 2 et comprend un corps réalisé en une matière souple et élastique et est conformée pour présenter une tête arrondie 5 raccordée à la paroi latérale 6 par une partie tronconique 7. The ball 4 is shown in more detail in FIG. 2 and comprises a body made of a flexible and elastic material and is shaped to have a rounded head 5 connected to the side wall 6 by a frustoconical part 7.
La partie latérale est prolongée par une jupe 8 qui va légèrement en s'évasant, une cavité tronconique 9 étant pratiquée à l'extrémité arrière pour former la jupe 8. The side part is extended by a skirt 8 which widens slightly, a frustoconical cavity 9 being formed at the rear end to form the skirt 8.
Ainsi l'épaisseur de la jupe 8 va en s' amincis- sant. Thus the thickness of the skirt 8 becomes thinner.
De préférence, la profondeur de la cavité 9 est légèrement inférieure à la moitié de la hauteur de la balle et le diamètre de la petite base de la cavité tronconique 9 est légèrement supérieur à la moitié du diamètre de la grande base de ladite cavité 9. Preferably, the depth of the cavity 9 is slightly less than half the height of the ball and the diameter of the small base of the frustoconical cavity 9 is slightly greater than half the diameter of the large base of said cavity 9.
Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention. Of course, the invention is not limited to the embodiment which has just been described and shown. Many detailed modifications can be made without departing from the scope of the invention.
