Abstract

The projectile is polyacetal. A low quantity of powder similar to that used in smooth bore hunting cartridges is used. The wadding, made of flexible material such as open cell cellular plastic, keeps the powder close to the fuse.

Description

La présente invention se rapporte à une munition d'entraînement pour armes à canon rayé. The present invention relates to a training ammunition for rifles with rifles.

L'invention vise, plus particulièrement, l'entraînement au tir pour la chasse. The invention relates, more particularly, to shooting training for hunting.

Le tir aux armes rayées nécessite des installations coûteuses compte tenu de ce que les projectiles parcourent des distances considérables. On doit, par conséquent, prévoir des buttes de terre suffisamment importantes pour éviter tous les risques d'accident. Shooting with rifled weapons requires expensive installations considering that the projectiles travel considerable distances. Consequently, earthy mounds must be provided that are large enough to avoid any risk of accident.

De plus, les munitions sont chères et bruyantes. In addition, ammunition is expensive and noisy.

L'un des buts de la présente invention est de réaliser une munition dont le projectile a une bonne précision, jusqu'à une distance de l'ordre d'une quarantaine de mètres, mais qui ensuite perd toute énergie cinétique. One of the aims of the present invention is to produce a munition whose projectile has good precision, up to a distance of the order of forty meters, but which then loses all kinetic energy.

La munition, selon l'invention, est du type comprenant un étui contenant de la poudre avec un culot pourvu d'une amorce et dont l'extrémité libre reçoit un projectile, ladite munition étant caractérisée en ce que le projectile est réalisé en matière plastique, la poudre de l'étui étant en faible quantité et correspondant aux poudres utilisées pour les cartouches de chasse des armes à canon lisse, un tampon de matière souple et élastique étant logé dans l?étui pour maintenir la poudre au voisinage de l'amorce. The ammunition according to the invention is of the type comprising a case containing powder with a base provided with a primer and the free end of which receives a projectile, said ammunition being characterized in that the projectile is made of plastic material , the powder in the case being in small quantity and corresponding to the powders used for hunting cartridges of smooth-barreled weapons, a pad of flexible and elastic material being housed in the case to keep the powder in the vicinity of the primer .

De préférence, le projectile est réalisé dans une matière plastique connue dans le commerce sous le nom de "ERTACETAL", cette matière étant auto-lubrifiante, ne se désagrégeant pas et pouvant être moulée ou travaillée, par exemple, tournée.  Preferably, the projectile is made of a plastic material known in the trade under the name of "ERTACETAL", this material being self-lubricating, not disintegrating and being able to be molded or worked, for example, turned.

Le tampon est réalisé dans une matière plastique cellulaire à cellules ouvertes.  The tampon is made of an open cell cellular plastic material.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté à la figure unique qui est une vue en coupe par un plan passant par l'axe 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 only and shown in the single figure which is a sectional view through a plane passing through the axis of a ammunition according to the invention.

La munition représentée à la figure unique comprend un étui 1 avec un culot 2 pourvu d'une amorce 4, le culot présentant un bourrelet 3 ou éventuellement une gorge suivant le type d'arme utilisée. The ammunition shown in the single figure comprises a case 1 with a base 2 provided with a primer 4, the base having a bead 3 or possibly a groove depending on the type of weapon used.

L'étui contient une charge de poudre 6 du type en paillettes telle que celle utilisée dans les cartouches pour armes à canon lisse. Cette charge de poudre est comprise entre 0,4 g à 0,8 g suivant le calibre de l'arme.  The case contains a powder charge 6 of the flake type such as that used in cartridges for smooth-barreled weapons. This powder charge is between 0.4 g to 0.8 g depending on the caliber of the weapon.

Afin de maintenir la poudre contre l'amorce dans l'étui 1, il est engagé un tampon 7 d'une matière plastique cellulaire souple et élastique, cette matière étant de préférence à cellules ouvertes. In order to hold the powder against the primer in the case 1, a pad 7 of a flexible and elastic cellular plastic material is engaged, this material preferably being open cell.

L'extrémité libre de l'étui 1 reçoit un projectile 8 réalisé en une matière plastique connue dans le commerce sous le nom de "ERTACETAL", ce produit vendu par la Société ERTA ENGINEERING PLASTICS étant un polyacétal. The free end of the case 1 receives a projectile 8 made of a plastic material known in the trade under the name of "ERTACETAL", this product sold by the company ERTA ENGINEERING PLASTICS being a polyacetal.

Une telle munition est peu bruyante ; comme la poudre utilisée n'est pas brisante, les étuis peuvent être rechargés indéfiniment. Such ammunition is not very noisy; as the powder used is not breaking, the cases can be recharged indefinitely.

Avec une telle munition, le projectile a une bonne précision jusqu'à 40 mètres environ, mais ensuite l'énergie cinétique tombe de sorte qu'il n'est pas dangereux au-delà de cette distance. I1 peut aussi être utilisé avec des installations beaucoup moins complexes que celles prévues pour les armes rayées.  With such ammunition, the projectile has good accuracy up to about 40 meters, but then the kinetic energy falls so that it is not dangerous beyond this distance. It can also be used with much less complex installations than those intended for rifled weapons.

Enfin, la munition, selon l'invention, est peu coûteuse et beaucoup moins fatigante à utiliser, le recul étant très faible. Finally, the ammunition according to the invention is inexpensive and much less tiring to use, the recoil being very low.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et repre- senté. 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.
