On va tout d'abord décrire le premier mode de réalisation illustré sur les figures 1 à 6.We will first describe the first embodiment illustrated in Figures 1 to 6.

La munition 10 conforme à la présente invention représentée sur ces figures annexées comprend essentiellement une douille 50 qui loge un projectile 100. A l'origine, c'est-à-dire au stockage, la munition 10, formée de la douille 50 et du projectile 100, est centrée sur un axe longitudinal 12.Ammunition 10 according to the present invention shown in these appended figures essentially comprises a socket 50 which houses a projectile 100. Originally, that is to say in storage, the ammunition 10, formed by the sleeve 50 and the projectile 100, is centered on an axis longitudinal 12.

La douille 50 comprend essentiellement un culot évasé 52 prolongé sur l'avant par une jupe cylindrique 60 centrée sur l'axe 12. Le culot 52 loge des moyens d'éjection/propulsion du projectile 100.The socket 50 essentially comprises a flared base 52 extended on the front by a cylindrical skirt 60 centered on the axis 12. The base 52 houses means for ejecting / propelling the projectile 100.

Ces moyens d'éjection/propulsion sont formés par exemple et non limitativement d'une amorce 54 associée à une charge pyrotechnique 56 formant générateur de gaz de propulsion, débouchant dans la chambre interne 62 de la douille 60, soit sur l'arrière du projectile 100.These ejection / propulsion means are formed for example and not limited to a primer 54 associated with a pyrotechnic charge 56 forming a propellant gas generator, opening into the chamber internal 62 of the socket 60, ie on the rear of the projectile 100.

Ce projectile 100 comprend essentiellement un corps 110, un coulisseau 120, un conteneur 130 de gaz propulsif sous pression et d'agent incapacitant et une ogive 140 associée à un percuteur 150.This projectile 100 essentially comprises a body 110, a slide 120, a container 130 of propellant under pressure and of agent incapacitating and a warhead 140 associated with a striker 150.

Le corps 110 présente de préférence une enveloppe cylindrique complémentaire de la chambre interne 62 de la douille 60. Le corps 110 posséde de préférence sur son extrémité arrière des moyens de stabilisation 112, par exemple sous forme d'une jupe 113, éventuellement munie de perforations ou ouïes traversantes, augmentant l'effet de stabilité, voire d'ailettes. Eventuellement la jupe 113 peut être souple pour s'expanser à la sortie du lanceur pour définir une traínée de stabilisation. Au voisinage du tiers de sa longueur considérée à partir de son extrémité arrière, le corps 110 est muni d'une cloison transversale 114. Le coulisseau 120 et le conteneur 130 sont placés dans la chambre 116 du corps 110 située en avant de la cloison transversale 114.The body 110 preferably has a cylindrical envelope complementary to the internal chamber 62 of the socket 60. The body 110 preferably has on its rear end means of stabilization 112, for example in the form of a skirt 113, possibly provided with through holes or gills, increasing the effect of stability, even fins. Optionally the skirt 113 can be flexible to expand at the exit of the launcher to define a stabilization train. In the vicinity of a third of its length considered from its end rear, the body 110 is provided with a transverse partition 114. The slide 120 and the container 130 are placed in the chamber 116 of the body 110 located in front of the transverse partition 114.

L'ogive 140 est fixée sur l'extrémité avant du corps 110. L'ogive 140 obture ainsi l'embouchure de la chambre 116 formée dans le corps 110. L'ogive 140 est de préféence réalisée à base de caoutchouc et présente une enveloppe hémisphérique convexe.The warhead 140 is fixed to the front end of the body 110. The warhead 140 thus closes the mouth of the chamber 116 formed in the body 110. The warhead 140 is preferably made from rubber and has a convex hemispherical envelope.

Le percuteur 150 est situé sur la face interne de l'ogive 140. Le percuteur 150 peut être formé par exemple d'une coupole 152 munie d'une pointe centrale 154 dont l'extrémité effilée est dirigée vers l'arrière, soit vers l'extrémité avant du conteneur 130.The striker 150 is located on the internal face of the warhead 140. The striker 150 can be formed for example of a dome 152 provided with a central point 154 whose tapered end is directed towards the rear, or towards the front end of the container 130.

Le coulisseau 120 est placé entre la cloison transversale 114 et le percuteur 154. Le coulisseau 120 est guidé à coulissement à l'intérieur de la chambre 116 du corps 110, selon l'axe 12.The slide 120 is placed between the transverse partition 114 and the striker 154. The slide 120 is guided to slide inside the chamber 116 of the body 110, along the axis 12.

Le conteneur 130 est lui-même placé sur le coulisseau 120, soit entre le fond du coulisseau 120 adjacent à la cloison transversale 114 et le percuteur 154.The container 130 is itself placed on the slide 120, i.e. between the bottom of the slide 120 adjacent to the transverse partition 114 and the striker 154.

Selon le mode de réalisation préférentiel de la présente invention, le conteneur 130 loge un agent incapacitant et un gaz propulseur sous pression. Il s'agit de préférence d'une réserve d'aérosol et d'un gaz sous pression servant de propulseur à cet aérosol après rupture du conteneur 130.According to the preferred embodiment of this invention, container 130 houses an incapacitating agent and a gas pressurized propellant. It is preferably an aerosol reserve and a pressurized gas serving as propellant for this aerosol after rupture of container 130.

Un ressort 160, tel qu'un ressort hélicoïdal est placé entre l'extrémité avant du conteneur 130 et le percuteur 154.A spring 160, such as a coil spring is placed between the front end of the container 130 and the striker 154.

En outre, dans le cadre de l'invention, il est prévu des moyens de sécurité qui interdisent le déplacement du coulisseau 120, et par conséquent du conteneur 130, en rapprochement du percuteur 154 avant que le corps 110 ne sorte de la douille 60.In addition, within the framework of the invention, means are provided. which prohibit the movement of the slide 120, and by consequent of the container 130, in approach of the striker 154 before that the body 110 does not come out of the socket 60.

De tels moyens de sécurité peuvent faire l'objet de différents modes de réalisation.Such security means can be the subject of different embodiments.

Selon le mode de réalisation préférentiel représenté sur les figures annexées, ces moyens de sécurité comprennent au moins une languette 118 venue du corps 110 et déformée élastiquement vers l'intérieur de la chambre 116 lorsque le projectile 100 est placé dans la douille 60, pour servir de butée au coulisseau 120. According to the preferred embodiment shown in the attached figures, these security means comprise at least one tongue 118 coming from the body 110 and elastically deformed towards inside the chamber 116 when the projectile 100 is placed in the socket 60, to serve as a stop for the slide 120.

Comme on l'exposera par la suite, lorsque le projectile 100 sort de la douille 60, la languette 118 libère le coulisseau 120 et par conséquent le conteneur 130.As will be explained below, when the projectile 100 leaves of the socket 60, the tongue 118 releases the slide 120 and consequently container 130.

De préférence, il est prévu plusieurs languettes 118 équi-réparties autour de l'axe 12.Preferably, several equi-distributed tongues 118 are provided. around axis 12.

De préférence, chaque languette 118 est formée d'une lame reliée au corps 110 par son extrémité la plus avant 119, une protubérance 117 étant prévue sur la face extérieure et sur l'extrémité arrière de la languette 118.Preferably, each tongue 118 is formed of a blade connected to the body 110 by its most forward end 119, a protuberance 117 being provided on the outer face and on the rear end of the tongue 118.

Le fonctionnement général de la munition conforme à la présente invention représentée sur les figures annexées et dont la structure vient d'être décrite, est essentiellement le suivant.The general functioning of the ammunition in accordance with the present invention shown in the accompanying figures and the structure just described, is basically the following.

En position de stockage (voir figures 1, 2 et 6A) le projectile 100 est situé dans la douille 50, 60. Chaque languette 118 est déformée vers l'intérieur de la chambre 116 par la douille extérieure 60, la protubérance 117 reposant sur la surface interne de la jupe 60. Ainsi, la ou les languettes bloque(nt) le coulisseau 120 et le conteneur 130 en éloignement du percuteur 154. Par contre, après expulsion du projectile 100 hors de la douille 60, par mise en oeuvre des moyens 54, 56, l'appui externe à la protubérance 117, formé précédemment par la douille 60, est supprimé. La languette 118 peut reprendre alors élastiquement sa position de repos dans l'alignement de l'épaisseur de la paroi du corps 110 (figures 3 et 6B). Ainsi, le coulisseau 120 est susceptible de déplacement selon l'axe 12 dans le corps 110.In the storage position (see Figures 1, 2 and 6A) the projectile 100 is located in the socket 50, 60. Each tab 118 is deformed towards the interior of the chamber 116 by the external sleeve 60, the protuberance 117 resting on the internal surface of the skirt 60. Thus, the tab or tabs blocks the slide 120 and the container 130 away from the striker 154. On the other hand, after expulsion of the projectile 100 from the socket 60, by using means 54, 56, external support to the protuberance 117, previously formed by the sleeve 60, is removed. The tongue 118 can then resiliently return to its rest position in aligning the thickness of the wall of the body 110 (FIGS. 3 and 6B). So, the slide 120 is capable of displacement along the axis 12 in the body 110.

Le projectile 100 est par conséquent armé.The projectile 100 is therefore armed.

Cependant, le ressort 160 interdit tout déplacement intempestif du coulisseau 120 et du conteneur 130 en rapprochement du percuteur 154.However, the spring 160 prohibits any inadvertent movement slide 120 and container 130 in proximity to the striker 154.

La portée et la vitesse du projectile 100 définies par la puissance des moyens de propulsion 54 et 56, sont adaptées pour éviter toute blessure à un individu I visé par le projectile 100.The range and speed of projectile 100 defined by power propulsion means 54 and 56, are adapted to avoid any injury to an individual I targeted by projectile 100.

Lors d'un impact sur un tel individu 1, la décélération résultante du projectile 100 entraíne un déplacement rapide du coulisseau 120 et du conteneur 130 vers l'avant, soit contre le percuteur 154, par compression du ressort 160. Upon impact on such an individual 1, the resulting deceleration of the projectile 100 causes rapid movement of the slide 120 and the container 130 towards the front, ie against the striker 154, by compression spring 160.

Lors de la percussion de l'extrémité avant du conteneur 130 par le percuteur 154, le conteneur 130 est perforé.Upon impact of the front end of the container 130 by the striker 154, the container 130 is perforated.

L'agent incapacitant, par exemple sous forme d'aérosol, contenu dans le conteneur 130 peut alors être libéré et diffusé sous l'effet du gaz propulseur stocké sous pression dans le conteneur 130 (figure 4).The incapacitating agent, for example in the form of an aerosol, contained in the container 130 can then be released and distributed under the effect propellant gas stored under pressure in the container 130 (Figure 4).

Cette diffusion de l'agent incapacitant peut être rendue performante si, comme illustré sur la figure 5, le ressort 160 entraíne ultérieurement un recul du coulisseau 120 et du conteneur 130 en éloignement du percuteur 154 pour libérer la perforation réalisée dans la paroi du conteneur 130 par ce percuteur 154.This diffusion of the incapacitating agent can be made efficient if, as illustrated in FIG. 5, the spring 160 drives subsequently a retreat of the slide 120 and of the container 130 in distance from striker 154 to release the perforation made in the wall of container 130 by this striker 154.

L'agent incapacitant placé dans le conteneur 130 est diffusé sur l'extérieur par l'intermédiaire d'au moins un orifice 170 formé dans la paroi du corps 110, au voisinage de son extrémité avant.The incapacitating agent placed in the container 130 is broadcast on the exterior via at least one orifice 170 formed in the wall of the body 110, in the vicinity of its front end.

Comme on le voit sur les figures 5 et 6D notamment, il est de préférence prévu plusieurs orifices 170 équi-répartis autour de l'axe 12 sur l'extrémité avant du corps 110, soit immédiatement en arrière de l'ogive 140. Cette disposition permet une diffusion ominidirectionnelle de l'agent actif contenu dans le projectile.As seen in Figures 5 and 6D in particular, it is preferably provided several orifices 170 equi-distributed around the axis 12 on the front end of the body 110, either immediately behind the 140 warhead. This arrangement allows omni-directional diffusion of the active agent contained in the projectile.

Bien entendu la présente invention n'est pas limitée au mode de réalisation particulier qui vient d'être décrit mais s'étend à toute variante conforme à son esprit.Of course, the present invention is not limited to the mode of particular embodiment which has just been described but extends to any variant conforms to his spirit.

La présente invention n'est pas limitée à la diffusion d'un agent actif particulier. Si elle concerne préférentiellement la diffusion d'un agent incapacitant, elle s'applique également à la diffusion d'agents actifs de nature différente, tels que par exemple une peinture, voire une combinaison de plusieurs agents actifs.The present invention is not limited to the dissemination of an agent particular asset. If it concerns preferentially the diffusion of a incapacitating agent, it also applies to the dissemination of active agents of a different nature, such as for example a painting, or even a combination of several active agents.

Par ailleurs l'agent actif peut se présenter sous de nombreuses formes, parmi lesquelles on peut citer sans être limitatif : des poudres, notamment des poudres dans un solvant, des fumigènes et des aérosols.In addition, the active agent can be presented under numerous forms, among which there may be mentioned without being limiting: powders, in particular powders in a solvent, fumigants and aerosols.

L'agent actif peut être stocké dans le même conteneur que le gaz propulseur sous pression ou dans une chambre séparée de celui-ci avant l'impact.The active agent can be stored in the same container as the propellant gas under pressure or in a chamber separate from it before impact.

Le gaz sous pression peut être stocké en permanence dans le conteneur 130 du projectile ou encore stocké dans le conteneur 130 au moment de l'expulsion du projectile 100, par transfert d'une partie des gaz générés par les moyens 54 et 56 dans le conteneur 130, grâce à un clapet prévu à cet effet en partie arrière du conteneur 130.The pressurized gas can be permanently stored in the container 130 of the projectile or stored in container 130 at moment of expulsion of projectile 100, by transfer of part of the gases generated by the means 54 and 56 in the container 130, by means of a valve provided for this purpose in the rear part of the container 130.

Selon encore une autre variante, le gaz assurant la diffusion de l'agent actif peut être généré par des moyens pyrotechniques initiés lors de l'impact sur le percuteur 154.According to yet another variant, the gas ensuring the diffusion of the active agent can be generated by pyrotechnic means initiated during impact on the striker 154.

On va maintenant décrire la variante de réalisation illustrée sur les figures 7, 8 et 9. On retrouve sur ces figures 7 à 9, une munition non létale conforme à la présente invention comprenant un corps 110 qui loge un conteneur 130 apte à générer un gaz sous pression et une ogive 140 associée à un percuteur 154 apte à permettre la diffusion d'un agent actif lors d'un impact.We will now describe the embodiment illustrated on Figures 7, 8 and 9. We find in these Figures 7 to 9, a munition not lethal according to the present invention comprising a body 110 which houses a container 130 capable of generating a gas under pressure and a warhead 140 associated with a striker 154 able to allow the diffusion of an active agent upon impact.

La structure du projectile illustrée sur les figures 7 à 9 ne sera donc pas décrite dans le détail par la suite.The structure of the projectile illustrated in Figures 7 to 9 will not therefore not described in detail below.

On s'attachera à décrire essentiellement les caractéritiques principales qui distinguent le projectile illustré sur les figures 7 à 9 de celui décrit précédemment en regard des figures 1 à 6.We will endeavor to describe essentially the characteristics principal which distinguish the projectile illustrated on figures 7 to 9 of that described above with reference to FIGS. 1 to 6.

En premier lieu, le projectile illustré sur les figures 7 à 9 se caractérise par la présence de moyens permettant d'assurer son autodestruction, en cas de défaut de fonctionnement.First, the projectile illustrated in Figures 7 to 9 is characterized by the presence of means to ensure its self-destruction, in the event of a malfunction.

En l'espèce, ces moyens d'autodestruction sont formés, de préférence, d'un retard pyrotechnique 200 situé dans le culot 52 du projectile. Le retard 200 est adapté pour être initié au départ du projectile. Ainsi, si le projectile n'a pas fonctionné normalement au bout d'un certain temps, par perforation du conteneur 130, par exemple si le projectile manque sa cible, le retard 200, à la fin de sa combustion, génère un volume de gaz qui vient forcer le conteneur 130 sur le percuteur 154.In this case, these means of self-destruction are formed, preferably, a pyrotechnic delay 200 located in the base 52 of the projectile. The delay 200 is adapted to be initiated at the start of the projectile. Thus, if the projectile did not operate normally after one some time, by puncturing the container 130, for example if the projectile misses its target, delay 200, at the end of its combustion, generates a volume of gas which forces the container 130 onto the striker 154.

En second lieu, afin de garantir la non létalité, le projectile illustré sur les figures 7 à 9 comprend une ogive 140 perfectionnée, sous forme d'une calotte hémisphérique, en silicone, de préférence, de dureté shoreA comprise entre 10 et 30, très préférentiellement entre 12 et 15.Second, in order to guarantee non-lethality, the projectile illustrated in FIGS. 7 to 9 comprises an improved warhead 140, under shape of a hemispherical cap, preferably silicone, of hardness shoreA between 10 and 30, very preferably between 12 and 15.

En troisième lieu, le projectile illustré sur les figures 7 à 9, se caractérise par une structure déformable 210 adjacente à l'ogive 140.Third, the projectile illustrated in Figures 7 to 9 is characterized by a deformable structure 210 adjacent to the warhead 140.

Une telle structure déformable 210 peut faire l'objet de nombreuses variantes de réalisation. Such a deformable structure 210 can be the subject of many variants.

Selon le mode de réalisation particulier illustré sur la figure 8, cette structure déformable 210 est constituée de la partie avant du corps 110, sous forme d'une enveloppe métallique mince, par exemple d'une épaisseur de 0,1 à 0,5mm, éventuellement pré-fragilisée, par exemple sous forme de marquages longitudinaux 212 répartis sur la périphérie du corps 110.According to the particular embodiment illustrated in FIG. 8, this deformable structure 210 consists of the front part of the body 110, in the form of a thin metallic envelope, for example a thickness of 0.1 to 0.5mm, possibly pre-weakened, for example under form of longitudinal markings 212 distributed around the periphery of the body 110.

A l'impact une telle structure déformable 210 absorbe une partie de l'énergie.On impact, such a deformable structure 210 absorbs a part of the energy.

On a illustré sur la figure 9, une variante adaptée à un fonctionnement par inertie et qui de plus favorise la dispersion de l'agent actif, l'aérosol par exemple, à l'impact. Plus précisément, la figure 9 illustre l'état du projectile après fonctionnement, c'est-à-dire après percussion du conteneur 130, par déformation de la structure 210.Illustrated in Figure 9, a variant adapted to a operation by inertia and which also promotes the dispersion of the agent active, aerosol for example, on impact. More specifically, Figure 9 illustrates the state of the projectile after operation, i.e. after percussion of the container 130, by deformation of the structure 210.

On notera que la variante de la figure 9 est dépourvue de retard 200.Note that the variant of Figure 9 is devoid of delay 200.

Bien entendu, la structure déformable 210 peut faire l'objet de nombreuses variantes de réalisation, par exemple sous forme d'amortisseurs déformables. Selon un mode de réalisation précis, il peut s'agir d'un amortisseur de choc à déformation plastique en tête de projectile réalisé sous forme d'un tube en aluminium adapté pour s'effondrer sur lui-même en absorbant une part de l'énergie cinétique et la transformer en énergie de déformation plastique, lors de l'impact.Of course, the deformable structure 210 can be the subject of numerous variants, for example in the form deformable shock absorbers. According to a specific embodiment, it can be a shock absorber with plastic deformation at the head of projectile produced in the form of an aluminum tube suitable for collapse on itself by absorbing a part of the kinetic energy and transform it into plastic deformation energy upon impact.

Selon les modes de réalisation précédemment décrits, le percuteur est fixe et le conteneur susceptible de déplacement. La disposition inverse peut être prévue, c'est-à-dire que le conteneur peut être fixe et le percuteur mobile lors de l'impact.According to the embodiments previously described, the striker is fixed and the container capable of displacement. The reverse arrangement may be provided, i.e. the container may be stationary and the striker mobile during impact.
