Description

La présente invention est relative à une grenade à fusil comprenant, de manière connue, une queue tubulaire métallique dont une extrémité est destinée à être assujettie à l'extrémité libre du canon d'un fusil, un piège à balles monté dans ladite queue et une tête de guerre fixée, éventuellement de manière amovible, à l'autre extrémité de la queue tubulaire qui est éventuellement munie d'un empennage.The present invention relates to a rifle grenade comprising, in a known manner, a metal tubular tail, one end of which is intended to be secured to the free end of the barrel of a rifle, a bullet trap mounted in said tail and a war head attached, possibly detachably, to the other end of the tubular tail which is optionally provided with a tail.

Il est connu de lancer les grenades à fusil, (telles que des grenades à charge creuse, des grenades anti-personnel, des grenades à fragmentation retardée, des grenades fumigènes ou des grenades à propulsion augmentée), à l'aide de cartouches à balles normales, notamment des cartouches à base de plomb. En raison de la nature et de la vitesse élevée de ces cartouches. à la sortie du canon d'un fusil, il est obligatoire de prévoir dans la grenade à fusil des pièges à balles, c'est-à-dire des éléments capables d'assurer une décélération rapide et prononcée des balles normales, de telle sorte que celles-ci soient retenues dans les pièges sans atteindre les grenades, tout en assurant le lancement de celles-ci.It is known to launch rifle grenades, (such as hollow charge grenades, anti-personnel grenades, delayed fragmentation grenades, smoke grenades or augmented propulsion grenades), using bullet cartridges normal, especially lead-based cartridges. Due to the nature and high speed of these cartridges. at the exit of the barrel of a rifle, it is compulsory to provide in the rifle grate with bullet traps, that is to say elements capable of ensuring a rapid and pronounced deceleration of normal bullets, so that these are retained in the traps without reaching the grenades, while ensuring the launching thereof.

Les pièges à balles connus de grenades à fusil sont constitués par des pièces montées dans la queue tubulaire de la grenade au voisinage de l'extrémité de cette queue, opposée à celle dans laquelle l'extrémité libre du canon d'un fusil est destinée à être enfilée.The known bullet traps of rifle grenades consist of parts mounted in the tubular tail of the grenade in the vicinity of the end of this tail, opposite to that in which the free end of the barrel of a rifle is intended for to be strung.

Les pièges à balles connus donnent satisfaction pour le lancement de grenades à fusil, dans le cas où ces grenades sont lancées à l'aide de balles normales.Known bullet traps are satisfactory for launching rifle grenades, in the case where these grenades are launched using normal bullets.

Cependant, à l'heure actuelle, on utilise de plus en plus fréquemment des balles à noyau d'acier qui présentent un danger certain lorsqu'elles sont utilisées pour lancer des grenades à fusil, en raison du fait que les pièges à balles dont sont munies ces grenades sont souvent incapables de retenir les balles à noyau d'acier.However, at present, steel core bullets are used more and more frequently which present a certain danger when they are used to launch rifle grenades, due to the fact that the bullet traps which are equipped with these grenades are often incapable of retaining bullets with a steel core.

La présente invention a pour objet une grenade à fusil munie d'un piège à balle universel, c'est-à-dire capable de retenir tant des balles normales que des balles à noyau d'acier de n'importe quel calibre.The present invention relates to a rifle grenade provided with a universal bullet trap, that is to say capable of retaining both normal bullets and steel core bullets of any caliber.

Suivant l'invention, le piège à balle monté dans la queue de la grenade à fusil comprend essentiellement, au voisinage de ladite autre extrémité de la queue, un premier élément capable d'absorber la dilatation d'une balle de type et de calibre quelconques, un second élément contigu au premier élément, suffisamment dur pour arrêter un noyau d'acier d'une balle à noyau d'acier et un troisième élément contigu au second élément, servant d'amortisseur, les trois éléments précités étant montés dans la queue susdite de l'amont vers l'aval de celle-ci.According to the invention, the bullet trap mounted in the tail of the rifle grenade essentially comprises, in the vicinity of said other end of the tail, a first element capable of absorbing the expansion of a bullet of any type and caliber , a second element contiguous to the first element, hard enough to stop a steel core from a steel core ball and a third element contiguous to the second element, serving as a shock absorber, the three aforementioned elements being mounted in the tail above from upstream to downstream thereof.

Le premier élément est avantageusement constitué d'un corps plein de forme cylindrique, par exemple en aluminium, fixé dans la queue par simple sertissage, le volume de ce premier élément étant tel qu'une balle tirée par le fusil auquel la grenade est reliée puisse venir s'y loger, en y créant un cratère.The first element advantageously consists of a solid body of cylindrical shape, for example aluminum, fixed in the tail by simple crimping, the volume of this first element being such that a bullet fired by the rifle to which the grenade is connected can come and stay there, creating a crater.

Pour empêcher qu'une balle recueillie dans le premier élément du piège à balle puisse endommager la paroi interne de la queue entourant ce premier élément, ce dernier est avantageusement muni au moins sur sa surface latérale d'une chemise ou enveloppe en une matière dure, par exemple en acier constituant un blindage. L'emploi d'une telle enveloppe de blindage s'est révélé approprié, lorsqu'une balle pénètre dans le premier élément du piège à balle dans une direction qui n'est pas coaxiale à l'axe longitudinal de la queue et du premier élément en question.To prevent a bullet collected in the first element of the bullet trap from damaging the inner wall of the tail surrounding this first element, the latter is advantageously provided at least on its lateral surface with a jacket or casing made of a hard material, for example steel constituting a shield. The use of such a shielding envelope has been found appropriate, when a bullet enters the first element of the bullet trap in a direction which is not coaxial with the longitudinal axis of the tail and of the first element. in question.

Le second élément du piège à balle qui est contigu au premier élément et est placé en aval du premier élément est avantageusement constitué d'un corps cylindrique plein en une matière plus dure que celle du premier élément, par exemple en acier dur ou en matière céramique. Ce second élément est destiné à arrêter le noyau d'acier d'une balle à noyau d'acier, lorsqu'une telle balle est utilisée pour lancer la grenade.The second element of the bullet trap which is contiguous to the first element and is placed downstream of the first element advantageously consists of a solid cylindrical body made of a material harder than that of the first element, for example of hard steel or ceramic material . This second element is intended to stop the steel core of a steel core ball, when such a ball is used to launch the grenade.

Le premier et le second éléments du piège à balle prévu dans la grenade à fusil suivant l'invention sont des corps pleins de forme cylindrique dont le diamètre correspond sensiblement au diamètre intérieur de la queue.The first and second elements of the bullet trap provided in the rifle grenade according to the invention are solid bodies of cylindrical shape whose diameter corresponds substantially to the inside diameter of the tail.

Quant au troisième élément du piège à balle, il est constitué d'un corps cylindrique en matière déformable capable d'absorber le choc provoqué par une balle pénétrant dans le premier élément et éventuellement dans le second élément. Ce troisième élément qui peut être, par exemple, un corps plein en aluminium ou en un alliage d'aluminium ou toute autre matière susceptible de faire amortisseur a, de préférence, un diamètre inférieur à celui du premier élément et du second élément, de manière à absorber, en se déformant dans la queue de la grenade, le choc provoqué par l'impact d'une balle pénétrant dans le premier élément et éventuellement dans le second élément du piège.As for the third element of the bullet trap, it consists of a cylindrical body of deformable material capable of absorbing the shock caused by a bullet penetrating into the first element and possibly into the second element. This third element which can be, for example, a solid body made of aluminum or an aluminum alloy or any other material capable of making a shock absorber, preferably has a diameter smaller than that of the first element and of the second element, so to absorb, by deforming in the tail of the grenade, the shock caused by the impact of a bullet penetrating in the first element and possibly in the second element of the trap.

Le troisième élément jouant le rôle d'amortisseur peut également agir sur un percuteur qui peut être logé dans un organe de fermeture de la queue à l'extrémité avant de celle-ci.The third element acting as a shock absorber can also act on a striker which can be housed in a member for closing the tail at the front end thereof.

Dans la présente description, les termes "amont" et "aval" désignent respectivement l'extrémité de la queue destinée à être enfilée sur le canon d'un fusil et l'extrémité opposée de la queue, sur laquelle est fixée, éventuellement de manière amovible, une tête de guerre.In the present description, the terms "upstream" and "downstream" respectively designate the end of the tail intended to be threaded on the barrel of a rifle and the opposite end of the tail, on which is fixed, possibly so removable, a war head.

D'autres particularités et détails de l'invention ressortiront de la description suivante des dessins ci-annexés qui représentent schématiquement et à titre d'exemple seulement une forme de réalisation d'une grenade à fusil suivant la présente invention.Other particularities and details of the invention will emerge from the following description of the attached drawings which schematically and by way of example only show one embodiment of a rifle grenade according to the present invention.

Dans ces dessins :

  • - la figure 1 montre, en coupe transversale, une grenade à fusil suivant l'invention et
  • - les figures 2 à 4 montrent en élévation respectivement le premier élément, le second élément et le troisième élément du piège à balle de la grenade à fusil montrée à la figure 1
In these drawings:
  • - Figure 1 shows, in cross section, a rifle grenade according to the invention and
  • - Figures 2 to 4 show in elevation respectively the first element, the second element and the third element of the bullet trap of the rifle grenade shown in Figure 1

Comme le montrent les dessins, la grenade à fusil comprend une queue tubulaire 1 en métal, par exemple en acier, dont une extrémité, à savoir l'extrémité d'amont 2 est destinée à être enfilée sur l'extrémité libre du canon d'un fusil (non représenté), et dont l'extrémité opposée, à savoir l'extrémité d'aval 3, porte une tète de guerre 4 qui peut y être fixée de manière amovible, comme décrit plus loin. A l'extrémité d'amont de la queue 1 est prévu un empennage 23.As the drawings show, the rifle grenade comprises a tubular tail 1 made of metal, for example steel, one end of which, namely the upstream end 2, is intended to be threaded onto the free end of the barrel. a rifle (not shown), the opposite end of which, namely the downstream end 3, carries a warhead 4 which can be fixed therein in a removable manner, as described below. At the upstream end of the tail 1 is provided a tail 23.

Dans l'extrémité d'aval 3 de la queue 1 est monté un piège à balle désigné, dans son ensemble, par la notation de référence 5. Ce piège se compose de trois éléments contigus centrés dans la queue 1.In the downstream end 3 of the tail 1 is mounted a bullet trap designated, as a whole, by the reference notation 5. This trap consists of three contiguous elements centered in the tail 1.

Le premier élément, représenté séparément à la figure 2, est constitué d'un corps cylindrique plein 6, par exemple en aluminium, en cuivre ou en un alliage de ces métaux, qui est avantageusement muni d'une enveloppe de blindage périphérique 7 et est fixé dans la queue 1 par exemple par sertissage. L'enveloppe de blindage 1 sert à empêcher qu'une balle pénétrant dans le premier élément 6 par son extrémité d'amont, dans une direction quelque peu inclinée par rapport à l'axe longitudinal de la queue 1. ne vienne endommager la paroi interne de cette queue. Pour permettre une fixation par sertissage, ce premier élément 6 peut être muni de cannelures 8 qui s'écrasent, lors de la mise en place de ce premier élément 6 par enfoncement sous pression du premier élément 6 dans l'enveloppe de blindage 7, cet élément 6 étant inséré dans la paroi interne de la queue. Ainsi, le premier élément 6 est maintenu coincé dans la queue 1, son diamètre étant d'ailleurs sensiblement égal, sinon très légèrement inférieur au diamètre intérieur de l'enveloppe de blindage 7.The first element, shown separately in FIG. 2, consists of a solid cylindrical body 6, for example made of aluminum, copper or an alloy of these metals, which is advantageously provided with a peripheral shielding casing 7 and is fixed in the tail 1 for example by crimping. The shielding envelope 1 is used to prevent a bullet entering the first element 6 through its upstream end, in a direction somewhat inclined relative to the longitudinal axis of the tail 1. from damaging the internal wall of this tail. To allow fixing by crimping, this first element 6 can be provided with grooves 8 which are crushed, during the installation of this first element 6 by pressing under pressure of the first element 6 in the shielding casing 7, this element 6 being inserted into the inner wall of the tail. Thus, the first element 6 is kept wedged in the tail 1, its diameter being moreover substantially equal, if not very slightly less than the inside diameter of the shielding envelope 7.

Le second élément du piège à balle 5 est constitué également d'un corps cylindrique plein 11 en une matière plus dure que celle dont est constitué le premier élément 1. Ce second élément 11 dont la hauteur peut être inférieure à celle du premier élément 6 sert à retenir le noyau d'une balle à noyau d'acier. Les balles à noyau d'acier, utilisées de plus en plus fréquemment à l'heure actuelle sont constituées d'un corps en plomb entouré d'une douille en cuivre et contenant un noyau d'acier dur, qui augmente la force de pénétration de la balle dans une cible.The second element of the bullet trap 5 also consists of a solid cylindrical body 11 made of a harder material than that of which the first element 1 is made. This second element 11, the height of which can be less than that of the first element 6 serves retaining the core of a steel core ball. Steel core bullets, used more and more frequently today, consist of a lead body surrounded by a copper sleeve and containing a hard steel core, which increases the penetration force of the ball into a target.

Grâce à l'emploi du premier élément 6 en matière relativement déformable et du second élément 11 en matière dure, le piège à balle 5 peut être considéré comme un piège à balle universel convenant pour être utilisé quel que soit le type de balle employé dans le fusil pour le lancement de la grenade. L'utilisateur du fusil n'a donc pas à se soucier du type de balle à utiliser pour le lancement d'une grenade.Thanks to the use of the first element 6 made of relatively deformable material and of the second element 11 made of hard material, the bullet trap 5 can be considered as a universal bullet trap suitable for being used whatever the type of bullet used in the rifle for launching the grenade. The rifle user therefore does not have to worry about the type of bullet to be used for launching a grenade.

Le second élément 11 du piège à balle 5, dont le diamètre correspond sensiblement au diamètre intérieur de la queue 1, présente deux cavités axiales opposées 12 et 13, la cavité 13-servant à recevoir le téton 16 d'un troisième élément 14 du piège.The second element 11 of the bullet trap 5, the diameter of which corresponds substantially to the internal diameter of the tail 1, has two opposite axial cavities 12 and 13, the cavity 13 serving to receive the stud 16 of a third element 14 of the trap .

La cavité 12 du second élément 11 sert à maintenir la trajectoire du projectile lors de son impact dans le centre de l'élément 11.The cavity 12 of the second element 11 serves to maintain the trajectory of the projectile during its impact in the center of the element 11.

Ce troisième élément 14 contigu à l'extrémité aval du second élément 11 sert à la fois à amortir le choc provoqué par l'impact d'une balle arrêtée dans le premier élément 6 et éventuellement dans le second élément 11 et à actionner un percuteur (dont il sera question plus loin).This third element 14 contiguous to the downstream end of the second element 11 serves both to absorb the shock caused by the impact of a bullet stopped in the first element 6 and possibly in the second element 11 and to actuate a striker ( which will be discussed later).

Le troisième élément 14 est constitué, dans la forme de réalisation représentée, par un corps plein déformable, par exemple en cuivre, en aluminium ou en un alliage de ces métaux, ce corps ayant également une forme cylindrique, dont le diamètre est cependant inférieur au diamètre intérieur de la queue 1. Lorsqu'une balle pénètre dans le premier élément 6 et lorsque, dans le cas d'une balle à noyau d'acier, ce dernier vient heurter le second élément 11, le choc provoqué par cette balle est amorti par le troisième élément 14 qui se déforme en s'écrasant, cette déformation étant possible grâce à l'espace annulaire libre 15 entourant ce troisième élément 14 à l'intérieur de la queue tubulaire 1. Ce troisième élément 14 est muni d'un téton de centrage 16 qui est inséré dans la cavité 13 du second élément 11 lors du montage du piège à balle dans la queue tubulaire1.The third element 14 is constituted, in the embodiment shown, by a solid deformable body, for example made of copper, aluminum or an alloy of these metals, this body also having a cylindrical shape, the diameter of which is however less than inside diameter of the tail 1. When a bullet enters the first element 6 and when, in the case of a steel core bullet, the latter strikes the second element 11, the shock caused by this bullet is absorbed by the third element 14 which deforms by crushing, this deformation being possible thanks to the free annular space 15 surrounding this third element 14 inside the tubular tail 1. This third element 14 is provided with a centering pin 16 which is inserted into the cavity 13 of the second element 11 during the mounting of the bullet trap in the tubular tail1.

Le troisième élément 14 jouant le rôle d'amortisseur présente, à son extrémité opposée à celle portant le téton 16, une cavité 17 dans laquelle est logée la base 18 d'un percuteur 19, dont le corps cylindrique 20 s'étend à travers un organe de fermeture 21 de l'extrémité d'amont de la queue tubulaire 1. Cet organe de fermeture 21 est constitué par une pastille cylindrique filetée, qui est également avantageusement réalisée en métal et qui est vissée dans l'extrémité d'aval 3 taraudée en 22 de la queue tubulaire 1.The third element 14 acting as a shock absorber has, at its end opposite to that carrying the stud 16, a cavity 17 in which is housed the base 18 of a striker 19, the cylindrical body 20 of which extends through a closure member 21 of the upstream end of the tubular tail 1. This closure member 21 is constituted by a threaded cylindrical disc, which is also advantageously made of metal and which is screwed into the downstream end 3 tapped at 22 of the tubular tail 1.

La tête de guerre 4 peut être fixée, également par vissage, à l'extrémité d'aval taraudée de la queue 1. Dans ce cas, on peut utiliser des types différents de têtes de guerre avec une même queue tubulaire munie d'un même piège à balle 5.The war head 4 can be fixed, also by screwing, to the threaded downstream end of the tail 1. In this case, different types of war heads can be used with the same tubular tail provided with the same bullet trap 5.

Il est évident que l'invention n'est pas limitée aux détails décrits plus haut et que diverses modifications peuvent être apportées à ces détails sans sortir du cadre de l'invention.It is obvious that the invention is not limited to the details described above and that various modifications can be made to these details without departing from the scope of the invention.

Ainsi, au lieu d'être constitué de trois élé≈- ments 6, 11 et 14, le piège à balle 5 peut ne comporter qu'un seul élément formé de trois parties fabriquées en une seule pièce réalisant les fonctions respectives des éléments 6, 11 et 14. Par ailleurs, l'élément amortisseur 14, au lieu d'être en métal, peut être en une matière élastomère et peut même présenter, dans ce cas, un diamètre seulement'légèrement inférieur au diamètre intérieur de la queue tubulaire 1. De plus, au lieu d'être vissé dans l'extrémité d'aval 3 de la queue 1, l'organe de fermeture 21 peut être constitué d'un capuchon éventuellement taraudé coiffant l'extrémité d'aval de la queue qui peut être filetée.Thus, instead of being made up of three elements 6, 11 and 14, the bullet trap 5 may comprise only a single element formed from three parts produced in one piece performing the respective functions of the elements 6, 11 and 14. Furthermore, the damping element 14, instead of being made of metal, may be made of an elastomeric material and may even have, in this case, a diameter which is only slightly smaller than the inside diameter of the tubular tail 1 In addition, instead of being screwed into the downstream end 3 of the tail 1, the closure member 21 may consist of an optionally threaded cap covering the downstream end of the tail which can be threaded.
