Description

MUNITION POUR EXERCICE DE TIR AMMUNITION FOR SHOOTING
L'invention est du domaine de l'armement. Elle a pour objet une munition pour la pratique du tir d'exercice et/ou du tir sportif, avec une arme à tir réel.The invention is in the field of armaments. Its purpose is ammunition for the practice of practice shooting and / or sport shooting, with a live fire weapon.
On rappelle qu'une munition comprend principalement un étui, ou douille, logeant dans une chambre interne une réserve d'explosif. Cette réserve d'explosif est en contact avec la face postérieure d'un projectile, balle notamment ou analogue telle que seringue. Ce projectile est supporté par l'étui à son extrémité antérieure qu'il prolonge axialement. La réserve d'explosif est aussi en contact avec une amorce située à l'extrémité postérieure de l'étui, cette amorce étant prévue pour être heurtée par le percuteur de l'arme. On comprendra donc que la munition comprend principalement l'étui délimitant un volume intérieur formant une chambre de réception d'une réserve d'explosif, cet étui recevant une suite d'éléments pour le fonctionnement en chaîne de la munition, depuis son extrémité postérieure vers son extrémité antérieure. Cette suite d'éléments comprend notamment l'amorce, la réserve d'explosif et le projectile.It will be recalled that a munition mainly comprises a case, or cartridge case, accommodating in an internal chamber a reserve of explosive. This explosive reserve is in contact with the rear face of a projectile, in particular a bullet or the like such as a syringe. This projectile is supported by the case at its anterior end which it extends axially. The explosive reserve is also in contact with a primer located at the rear end of the holster, this primer being intended to be struck by the striker of the weapon. It will therefore be understood that the munition mainly comprises the case delimiting an interior volume forming a chamber for receiving an explosive reserve, this case receiving a series of elements for the chain operation of the ammunition, from its rear end towards its anterior end. This series of elements notably includes the primer, the explosive reserve and the projectile.
L'étui, de conformation générale tronconique effilée à son extrémité antérieure, est habituellement formé d'un fût en laiton de faible épaisseur, pour optimiser le volume de la chambre de réception de l'explosif au regard de l'encombrement global de la munition. C'est pourquoi, un problème posé réside dans l'utilisation d'une arme agencée pour recevoir une munition à tir réel, pour la pratique du tir d'exercice et/ou du tir sportif. Dans ce cas, il est nécessaire de réduire la quantité d'explosif contenu dans la chambre interne de l'étui. Pour cela, il est habituel de compenser le volume manquant d'explosif par un matériau inerte de substitution.The case, of generally frustoconical conformation tapered at its anterior end, is usually formed of a thin brass barrel, to optimize the volume of the explosive receiving chamber with regard to the overall bulk of the ammunition . This is why, a problem posed resides in the use of a weapon arranged to receive a live-fire ammunition, for the practice of practice shooting and / or sport shooting. In this case, it is necessary to reduce the amount of explosive contained in the internal chamber of the case. For this, it is usual to compensate for the missing volume of explosive with an inert substitute material.
Le but de la présente invention est de proposer une munition pour la pratique du tir d'exercice et/ou du tir sportif, avec une arme individuelle à tir réel.The object of the present invention is to provide ammunition for the practice of practice shooting and / or sport shooting, with an individual live-fire weapon.
A cet effet, l'invention a trait une munition pour la pratique du tir d'exercice et/ou du tir sportif avec une arme individuelle à tir réel qui comprend un étui délimitant un volume intérieur formant une chambre de réception d'une réserve d'explosif, cet étui recevant successivement une suite d'éléments pour le fonctionnement en chaîne de la munition, depuis son extrémité postérieure vers son extrémité antérieure, comprenant une amorce, la réserve d'explosif et un projectile. Cette munition est caractérisée en ce que le volume de la chambre interne de l'étui est diamétralement réduit de manière à conférer à la chambre une dimension transversale au plus de l'ordre de celle de la face postérieure du projectile.To this end, the invention relates to ammunition for the practice of practice shooting and / or sport shooting with an individual live-fire weapon which comprises a case defining an interior volume forming a chamber. reception of an explosive reserve, this case successively receiving a series of elements for the chain operation of the ammunition, from its rear end to its front end, comprising a primer, the explosive reserve and a projectile. This munition is characterized in that the volume of the internal chamber of the case is diametrically reduced so as to give the chamber a transverse dimension at most of the order of that of the rear face of the projectile.
La présente invention va être décrite en relation avec les figures de la planche annexée, dans laquelle planche : la fig.1 est une vue schématique d'une munition de l'art antérieur, les fig.2, fig.3, fig.4 et fig.5 représentent schématiquement des munitions selon diverses variantes respectives et préférées de réalisation de l'invention ; la fig.3A est une vue, à plus grande échelle et en demi-coupe, d'une partie de la munition de la figure 3 et la fig.6 est une vue analogue à la figure 3A pour une munition conforme à un cinquième mode de réalisation de l'invention.The present invention will be described in relation to the figures of the appended plate, in which plate: fig.1 is a schematic view of a munition of the prior art, fig.2, fig.3, fig.4 and Fig.5 schematically represent ammunition according to various respective and preferred embodiments of the invention; Fig.3A is a view, on a larger scale and in half-section, of a part of the ammunition of Figure 3 and Fig.6 is a view similar to Figure 3A for ammunition according to a fifth mode for carrying out the invention.
Sur la fig.1 , une munition de l'art antérieur comprend un étui 1 qui : a) supporte un projectile 2 à son extrémité antérieure 3, b) délimite un volume intérieur formant une chambre 4 de réception d'un explosif 5, c) supporte une amorce 6 à son extrémité postérieure 7. On remarquera que la paroi de l'étui 1 , en laiton, est une paroi fine ménageant une chambre interne 4 d'un volume sensiblement équivalent à celui global extérieur de l'étui 1. On notera aussi que la suite d'éléments participant du fonctionnement habituel en chaîne de la munition comprend successivement l'amorce 6, l'explosif 5 et le projectile 2. L'étui 1 est pourvu, au niveau de son extrémité 3, d'un collet 31 monobloc avec l'étui 1 et qui entoure le projectile 2. Ce collet 31 permet de maintenir efficacement le projectile par emboîtement. En outre, l'étui 1 est équipé, à l'opposé de l'extrémité 3, d'une gorge 11. En variante, un bourrelet peut être prévu au pied de l'étui 1.In fig.1, a munition of the prior art comprises a case 1 which: a) supports a projectile 2 at its front end 3, b) delimits an interior volume forming a chamber 4 for receiving an explosive 5, c ) supports a primer 6 at its rear end 7. It will be noted that the wall of the case 1, made of brass, is a thin wall providing an internal chamber 4 with a volume substantially equivalent to that of the overall outside of the case 1. It will also be noted that the series of elements participating in the usual chain operation of the ammunition successively comprises the primer 6, the explosive 5 and the projectile 2. The case 1 is provided, at its end 3, with a one-piece collar 31 with the case 1 and which surrounds the projectile 2. This collar 31 makes it possible to effectively hold the projectile by interlocking. In addition, the case 1 is equipped, opposite the end 3, with a groove 11. As a variant, a bead can be provided at the foot of the case 1.
L'étui 1 a une forme extérieure globalement en tronc de cône.The case 1 has an outer shape generally in a truncated cone.
Sur les fig.2 à fig.5, diverses variantes de la présente invention sont schématiquement illustrées, dont la démarche générale a consisté à rompre les habitudes prises dans le domaine, et à réduire le volume de la chambre interne 4 de l'étui 1. Sur la fig.2, cette réduction de volume est effectuée au moins diamétralement, notamment par un accroissement de l'épaisseur e de l'étui 1 , qui est alors avantageusement formé d'une masse évidée de résine. Ces dispositions confèrent à la chambre 4 une dimension transversale maximale PJ_ au plus de l'ordre de celle D2 de la face postérieure du projectile 2. Le fait que PJ_ soit au plus de l'ordre de D2 signifie, en pratique, que p_l est inférieure à environ 1 ,2 fois D2. On comprendra que l'évidemment de la masse en résine formant l'étui 1 forme la chambre 4 de réception de l'explosif.In fig. 2 to fig. 5, various variants of the present invention are schematically illustrated, the general approach of which consisted in breaking the habits adopted in the field, and in reducing the volume of the internal chamber 4 of the case 1 In FIG. 2, this reduction in volume is carried out at least diametrically, in particular by an increase in the thickness e of the case 1, which is then advantageously formed from a hollowed out mass of resin. These provisions give the chamber 4 a maximum transverse dimension PJ_ at most of the order of that D2 of the rear face of the projectile 2. The fact that PJ_ is at most of the order of D2 means, in practice, that p_l is less than about 1.2 times D2. It will be understood that the mass of resin forming the case 1 obviously forms the chamber 4 for receiving the explosive.
La forme extérieure de l'étui 1 est sensiblement la même que celle de l'étui de la figure 1. Sur les fig.3 à fig.5, la réduction du volume de la chambre interne 4 de l'étui 1 est aussi de préférence une réduction de dimension longitudinale. Celle-ci est compensée par l'interposition entre deux quelconques au moins des éléments 6, 5, et 2, rendus distants, qui participent de la suite d'éléments pour le fonctionnement en chaîne de la munition, de moyens de mise en relation positive entre ces deux éléments distants.The external shape of the case 1 is substantially the same as that of the case of FIG. 1. In fig.3 to fig.5, the reduction in the volume of the internal chamber 4 of the case 1 is also preferably a reduction in longitudinal dimension. This is compensated for by the interposition between any two at least of elements 6, 5, and 2, made distant, which participate in the series of elements for the chain operation of the ammunition, of positive connection means. between these two distant elements.
Par exemple sur la fig.3, les moyens de mise en relation sont constitués par un percuteur annexe 8 interposé entre l'amorce 6 et la face d'extrémité postérieure 9 de la munition, contre laquelle est prévue d'être appliqué le choc du percuteur de l'arme. Le percuteur intermédiaire 8, qui transmet l'action du percuteur de l'arme à l'amorce 6, permet le rapprochement de l'amorce et de l'explosif.For example in fig.3, the connecting means are constituted by an annex striker 8 interposed between the primer 6 and the rear end face 9 of the ammunition, against which the shock of the weapon striker. The intermediate striker 8, which transmits the action of the striker of the weapon to the primer 6, allows the approximation of the primer and the explosive.
La douille 1 est pourvue, au voisinage de son extrémité 3, d'un relief circulaire 32 qui vient en engagement avec un relief 22 de forme correspondante ménagé sur le projectile 2. Le relief formé sur le projectile 2 est également circulaire.The sleeve 1 is provided, in the vicinity of its end 3, with a circular relief 32 which comes into engagement with a relief 22 of corresponding shape formed on the projectile 2. The relief formed on the projectile 2 is also circular.
A cet égard, on peut noter que la liaison des reliefs 22 et 32, qui maintient le projectile dans l'étui pendant le stockage de la munition, est fortement renforcé par la pression due à la fermeture de l'arme, juste avant le tir, ceci par un effet de coin, car l'extrémité 3 porte sur la partie tronconique de géométrie complémentaire formée par le canon de l'arme.In this regard, it can be noted that the connection of the reliefs 22 and 32, which keeps the projectile in the case during the storage of the ammunition, is strongly reinforced by the pressure due to the closing of the weapon, just before firing , this by a wedge effect, because the end 3 bears on the frustoconical part of complementary geometry formed by the barrel of the weapon.
Lors de l'explosion, les reliefs 22 et 32 sont déformés temporairement pour permettre l'éjection du projectile 2. Le projectile 2 comprend essentiellement trois parties, à savoir :During the explosion, the reliefs 22 and 32 are temporarily deformed to allow the projectile 2 to be ejected. The projectile 2 essentially comprises three parts, namely:
- une extrémité avant 23 dont le diamètre est au maximum égal à celui du canon de l'armea front end 23 whose diameter is at most equal to that of the barrel of the weapon
- une partie intermédiaire 24 dont le diamètre est égal à celui du fond des rayures internes du canon de l'arme- An intermediate part 24 whose diameter is equal to that of the bottom of the internal scratches of the barrel of the weapon
- une partie arrière 25 qui porte le relief 22 destiné au maintien du projectile 2 dans l'étui 1. Cette partie est déformée lors de son passage dans le canon.- A rear part 25 which carries the relief 22 intended to hold the projectile 2 in the case 1. This part is deformed during its passage through the barrel.
Comme le projectile 2 est plus court que les balles de tir réel, sa géométrie particulière facilite la prise des rayures du canon, tout en conservant une bonne trajectoire, avec un mouvement de rotation.As the projectile 2 is shorter than the bullets of real shooting, its particular geometry facilitates the taking of the scratches of the gun, while maintaining a good trajectory, with a rotational movement.
Sur une première partie 12, l'étui 1 a une forme extérieure tronconique avec un angle au sommet relativement grand. Sur une seconde partie 13, l'étui est de forme extérieure également tronconique avec un angle au sommet relativement petit, ce qui lui permet de s'adapter à la chambre de l'arme. Sur une troisième partie 14, l'étui 1 est globalement cylindrique à section circulaire, ce qui permet d'améliorer l'élasticité de l'étui et de faciliter la déformation de l'extrémité 3 pour la libération du projectile après l'explosion de l'explosif 5. Cette géométrie cylindrique permet également de simplifier l'outillage de fabrication des étuis et de s'accommoder des tolérances de fabrication des armes et des munitions. Cette partie permet également de concevoir une arme avec un canon spécifique à cette munition de faible énergie interdisant l'usage de munitions de tir réel. L'étui 1 est également pourvu d'un épaulement 15 qui facilite la prise de la munition avec l'extracteur de l'arme et facilite l'obtention de l'étui par moulage.On a first part 12, the case 1 has a frustoconical external shape with a relatively large apex angle. On a second part 13, the holster is also tapered in external shape with a relatively small apex angle, which allows it to adapt to the chamber of the weapon. On a third part 14, the case 1 is generally cylindrical with a circular section, which makes it possible to improve the elasticity of the case and to facilitate the deformation of the end 3 for the release of the projectile after the explosion of explosive 5. This cylindrical geometry also makes it possible to simplify the tooling for manufacturing cases and to accommodate the manufacturing tolerances of weapons and ammunition. This part also makes it possible to design a weapon with a barrel specific to this ammunition of low energy prohibiting the use of ammunition of real shooting. The case 1 is also provided with a shoulder 15 which facilitates the taking of the ammunition with the extractor of the weapon and facilitates the obtaining of the case by molding.
Sur la fig.4, les moyens de mise en relation sont constitués par la chambre interne 4 de l'étui 1 , celle-ci constituant non seulement une chambre de réception de l'explosif 5, mais aussi une chambre de réception du projectile 2 à l'intérieur de l'étui 1.In Fig.4, the connecting means are constituted by the internal chamber 4 of the case 1, this constituting not only a chamber for receiving the explosive 5, but also a chamber for receiving the projectile 2 inside the case 1.
Sur la fig.5, les moyens de mise en relation sont constitués par un organe 10 à extension axiale prolongeant la face postérieure du projectile 2 vers la réserve d'explosif 5. Dans ces cas, l'organe 10 constitue la queue d'une seringue formant le projectile 2 et pourvue d'une aiguille 2a. Ce mode de réalisation concerne des tirs de capture.In Fig.5, the connecting means are constituted by a member 10 with axial extension extending the rear face of the projectile 2 towards the explosive reserve 5. In these cases, the member 10 constitutes the tail of a syringe forming the projectile 2 and provided with a needle 2a. This embodiment relates to capture shots.
Les munitions des modes de réalisation des figures 4 et 5 ont des étuis 1 de même géométrie externe que celui représenté à la figure 2. Elles pourraient également comprendre des étuis de géométrie externe analogue à celle de l'étui de la figure 3. En variante, dans les modes de réalisation des figures 4 et 5, les parties de l'étui 1 au niveau desquelles il n'y a pas d'explosif peuvent être cylindriquesThe ammunition of the embodiments of Figures 4 and 5 have cases 1 of the same external geometry as that shown in Figure 2. They could also include cases of external geometry similar to that of the case of Figure 3. Alternatively , in the embodiments of Figures 4 and 5, the parts of the case 1 at which there is no explosive can be cylindrical
Comme il ressort de la comparaison des figures 2 à 5 avec la figure 1 , une munition conforme à l'invention est plus courte que celle de l'art antérieur.As appears from the comparison of Figures 2 to 5 with Figure 1, a munition according to the invention is shorter than that of the prior art.
Selon des variantes non représentées de l'invention, l'extrémité avant 3 de l'étui 1 peut être équipée d'un petit collet facilitant l'emboîtement du projectile 2 dans l'étui. Les modes de réalisation des figures 2 à 4 sont particulièrement adaptés à la plupart des tirs d'exercice et des tirs sportifs, notamment des tirs effectués pour la préparation et l'examen du permis de chasser français, ces tirs s'effectuant sur cibles mobiles. Cependant, dans certains cas, comme pour la préparation de chasse à l'affût ou à l'approche, on utilise des cibles fixes placées à des distances du tireur plus grandes que dans le cas de cibles mobiles.According to variants not shown of the invention, the front end 3 of the case 1 can be equipped with a small collar facilitating the fitting of the projectile 2 into the case. The embodiments of FIGS. 2 to 4 are particularly suitable for most exercise shots and sport shots, in particular shots carried out for the preparation and examination of the French hunting license, these shots being carried out on moving targets . However, in certain cases, such as for hunting for a lookout or for an approach, fixed targets are used placed at greater distances from the shooter than in the case of moving targets.
Pour ce genre de tirs, on augmente la masse du projectile 2 qui, comme représenté à la figure 6, comporte une partie en métal 26 et une partie en matière synthétique 27 dans laquelle est logée la partie 26. Comme précédemment un relief 22 est prévu sur le projectile pour coopérer avec un relief 32 de l'extrémité avant 3 de l'étui 1. Cette variante avec projectile « lourd » peut également être utilisée pour tir réel ou de chasse.For this type of shooting, the mass of the projectile 2 is increased, which, as shown in FIG. 6, includes a metal part 26 and a part made of synthetic material 27 in which the part 26 is housed. As previously, a relief 22 is provided on the projectile to cooperate with a relief 32 of the front end 3 of the case 1. This variant with "heavy" projectile can also be used for live fire or hunting.
Les caractéristiques techniques des différents modes de réalisation peuvent être combinées entre elles sans sortir du cadre de la présente invention. The technical characteristics of the various embodiments can be combined with one another without departing from the scope of the present invention.
