Description

L'invention se situe dans le domaine technique de l'extraction de munition d'un tube canon, par exemple (non limitatif) un mortier de 120 mm rayé. L'invention trouve une application particulièrement avantageuse dans le cas d'une munition coincée dans le tube ou lors d'un non-feu.The invention lies in the technical field of the extraction of ammunition from a cannon tube, for example (not limited to) a rifled 120 mm mortar. The invention finds a particularly advantageous application in the case of ammunition stuck in the tube or during a non-fire.

Actuellement l'extraction d'une munition se fait à l'aide d'un extracteur à griffes attaché à une corde. Un tel extracteur 5 de l'art antérieur est représenté sur la figure 1. L'extracteur 5 est glissé dans le tube canon par un utilisateur. L'extracteur 5 comprend un ensemble de griffes 6, qui s'accrochent par gravité sur la fusée 7 de la munition. On entend ici par fusée la pointe avant de la munition. Ensuite, l'utilisateur extrait la munition à l'aide de la corde attachée à une poignée 8 de l'extracteur 5. Ce procédé est utilisé par l'ensemble de la profession mais l'utilisation d'un tel système a des limites techniques. Il ne permet pas de décoincer une munition coincée au niveau de la bouche du tube canon. En outre, il faut adapter l'extracteur aux différents types de fusées utilisées sur les munitions. De plus il génère des risques pour l'utilisateur : lors de l'insertion de l'extracteur dans le tube canon, l'utilisateur est contraint de passer sa main devant la bouche du tube et lors de la sortie de la munition du tube canon, si l'utilisateur positionne mal ses mains il peut décrocher l'extracteur et faire retomber la munition au fond du tube canon, avec un risque de mise à feu non souhaitée de la munition.Currently the extraction of ammunition is done using a claw extractor attached to a rope. Such an extractor 5 of the prior art is shown in figure 1 . The extractor 5 is slipped into the barrel tube by a user. The extractor 5 comprises a set of claws 6, which hang by gravity on the rocket 7 of the ammunition. The term fuze is understood here to mean the front point of the munition. Then, the user extracts the ammunition using the rope attached to a handle 8 of the extractor 5. This process is used by the entire profession but the use of such a system has technical limitations. . It does not release ammunition stuck at the muzzle of the barrel tube. In addition, the extractor must be adapted to the different types of rockets used on the ammunition. In addition, it generates risks for the user: when inserting the extractor into the barrel tube, the user is forced to pass his hand in front of the mouth of the tube and when removing the ammunition from the barrel tube. , if the user positions his hands incorrectly, he can unhook the extractor and drop the ammunition to the bottom of the barrel tube, with a risk of unwanted ignition of the ammunition.

Le document CH 624 480 décrit un dispositif et procédé d'extraction d'une munition d'un canon par injection d'air comprimé. Ce procédé repose sur la régulation de pression d'air comprimé injecté pour faire en sorte que la munition sorte du canon tout juste pour être saisie. Ce procédé nécessite un appareillage complexe de régulation de pression. En outre, il expose à une chute de la munition extraite de la hauteur séparant le sol et la bouche du canon. Il en résulte un risque de mise en détonation de la munition.Document CH 624 480 describes a device and method for extracting ammunition from a gun by injecting compressed air. This process relies on regulating the pressure of injected compressed air to ensure that the ammunition comes out of the barrel just to be gripped. This process requires a complex pressure regulation apparatus. In addition, it exposes the ammunition extracted from the height separating the ground and the muzzle to a fall. This results in a risk of detonation of the ammunition.

L'invention vise à pallier tout ou partie des problèmes cités plus haut en proposant un berceau de réception qui permet de réceptionner une munition extraite par un moyen d'expulsion de la munition du tube, notamment par injection d'air comprimé, quelle que soit la fusée. Le berceau de réception permet en outre de recueillir des munitions coincées à la bouche après l'expulsion du tube de la munition par tout moyen d'expulsion adapté. Un tel dispositif est particulièrement sécuritaire du fait que l'utilisateur ne passe jamais tout ou partie de son corps devant la bouche du canon. Le risque de faire retomber la munition au fond du tube est aussi éliminé.The invention aims to overcome all or part of the problems mentioned above by proposing a receiving cradle which makes it possible to receive an ammunition extracted by a means of expelling the ammunition from the tube, in particular by air injection. compressed, regardless of the rocket. The receiving cradle also makes it possible to collect ammunition stuck in the muzzle after the expulsion of the ammunition tube by any suitable expulsion means. Such a device is particularly safe because the user never passes all or part of his body in front of the muzzle. The risk of dropping the ammunition to the bottom of the tube is also eliminated.

A cet effet, l'invention a pour objet un berceau de réception destiné à réceptionner une munition extraite d'un tube s'étendant selon un premier axe X par un moyen d'expulsion comprenant :

  1. a. Une structure comprenant une embase de fixation destinée à être fixée à une extrémité de sortie du tube ;
  2. b. Un sac de réception s'étendant sensiblement selon le premier axe X fixé à la structure, destiné à réceptionner la munition.
To this end, the invention relates to a receiving cradle intended to receive a munition extracted from a tube extending along a first axis X by an expulsion means comprising:
  1. at. A structure comprising a fixing base intended to be fixed to an outlet end of the tube;

Sur ces figures, dans un souci de clarté, les échelles ne sont pas respectées d'une figure à une autre. Par ailleurs, les mêmes éléments porteront les mêmes repères dans les différentes figures.In these figures, for the sake of clarity, the scales are not respected from one figure to another. Furthermore, the same elements will bear the same references in the different figures.

La figure 1 représente schématiquement un extracteur connu de l'art antérieur et a déjà été présentée en introduction.The figure 1 schematically represents an extractor known from the prior art and has already been presented in the introduction.

La figure 2 représente schématiquement un berceau de réception 10 mis en place en sortie d'un tube selon l'invention. Le berceau de réception 10 est destiné à réceptionner une munition 11 extraite d'un tube 12 s'étendant selon un premier axe X par un moyen d'expulsion 13 , le berceau de réception 10 comprenant une structure 14 et un sac de réception 17 s'étendant sensiblement selon le premier axe X fixé à la structure 14, destiné à réceptionner la munition 11. L'invention s'applique à tout moyen d'expulsion adapté, par exemple par injection d'air comprimé, injection de gaz inerte ou par application d'une force sur la munition par l'arrière. Par la suite, nous assimilerons le moyen d'expulsion à l'injection d'air comprimé, sans pour autant limiter l'invention à cet exemple. Une munition 11 ayant une longueur sensiblement égale à la longueur du berceau de réception est représentée. Toutefois, l'invention s'applique quelle que soit la longueur et le diamètre de la munition pourvu que la longueur et le diamètre de la munition soient inférieurs à ceux du berceau de réception 10. La structure 14 peut par exemple être en aluminium afin d'alléger au maximum sa masse.The figure 2 schematically shows a receiving cradle 10 placed at the outlet of a tube according to the invention. The reception cradle 10 is intended to receive an ammunition 11 extracted from a tube 12 extending along a first axis X by an expulsion means 13, the reception cradle 10 comprising a structure 14 and a reception bag 17 s 'extending substantially along the first axis X fixed to the structure 14, intended to receive the ammunition 11. The invention applies to any suitable expulsion means, for example by injection of compressed air, injection of inert gas or by application of force to the ammunition from the rear. Subsequently, we will assimilate the expulsion means to the injection of compressed air, without limiting the invention to this example. An ammunition 11 having a length substantially equal to the length of the receiving cradle is shown. However, the invention applies whatever the length and the diameter of the ammunition, provided that the length and the diameter of the ammunition are less than those of the reception cradle 10. The structure 14 can for example be made of aluminum in order to '' lighten its mass as much as possible.

La figure 3 représente schématiquement la structure 14 du berceau de réception 10 selon l'invention, en configuration dépliée et repliée. La structure 14 est en configuration dépliée sur la gauche de la figure et en configuration repliée sur la droite de la figure. La structure 14 comprend une embase de fixation 15 destinée à être fixée à une extrémité 16 de sortie du tube 12. La structure 14 comprend avantageusement un premier bras 21 et un second bras 22, chacun étant relié en une première extrémité 19 à l'embase de fixation 15. Les bras 21, 22 sont représentés sensiblement parallèles entre eux et au premier axe X. Toutefois, cette configuration, bien que préférée n'est pas obligatoire, et les deux bras 21, 22 peuvent s'étendre selon deux directions divergentes ou convergentes. Le sac de réception 17 est fixé aux deux bras 21, 22 et à l'embase de fixation 15.The figure 3 schematically shows the structure 14 of the receiving cradle 10 according to the invention, in the unfolded and folded configuration. The structure 14 is in the unfolded configuration on the left of the figure and in the folded configuration on the right of the figure. The structure 14 comprises a fixing base 15 intended to be fixed to an outlet end 16 of the tube 12. The structure 14 advantageously comprises a first arm 21 and a second arm 22, each being connected at a first end 19 to the base. fixing 15. The arms 21, 22 are shown substantially parallel to each other and to the first axis X. However, this configuration, although preferred is not mandatory, and the two arms 21, 22 can extend in two divergent directions or convergent. The receiving bag 17 is fixed to the two arms 21, 22 and to the fixing base 15.

La figure 4 représente schématiquement un berceau de réception 10 selon l'invention. L'embase de fixation 15 a une forme en U, une portion intérieure 23 étant destinée à être en contact avec une portion extérieure 24 de l'extrémité 16 de sortie du tube 12, comme cela est visible sur la figure 7. Le sac de réception 17 est fixé à l'embase de fixation 15 au niveau de sa portion intérieure 23, c'est-à-dire dans la partie centrale du U, et au niveau des extrémités supérieures, c'est-à-dire au niveau des parties s'étendant depuis la partie centrale du U et de part et d'autre de la partie centrale du U.The figure 4 schematically shows a receiving cradle 10 according to the invention. The fixing base 15 has a U-shape, an inner portion 23 being intended to be in contact with an outer portion 24 of the outlet end 16 of the tube 12, as can be seen in the figure. figure 7 . The receiving bag 17 is fixed to the fixing base 15 at the level of its interior portion 23, that is to say in the central part of the U, and at the level of the upper ends, that is to say at the level of the parts extending from the central part of the U and on either side of the central part of the U.

La figure 5 représente schématiquement une première vue d'un sac de réception 17 du berceau de réception 10 selon l'invention. Le sac de réception 17 comprend un cône d'arrêt 25 positionné à une seconde extrémité 26 des deux bras 21, 22, configuré pour former une butée à la munition 11, et un dispositif de maintien 27 du cône d'arrêt 25 reliant le cône d'arrêt 25 aux deux bras 21, 22 et à l'embase de fixation 15.The figure 5 schematically shows a first view of a receiving bag 17 of the receiving cradle 10 according to the invention. The receiving bag 17 comprises a stop cone 25 positioned at a second end 26 of the two arms 21, 22, configured to form a stop for the ammunition 11, and a holding device 27 for the stop cone 25 connecting the cone. stop 25 to the two arms 21, 22 and to the mounting base 15.

Le cône d'arrêt 25 constitue un élément majeur du berceau de réception 10 selon l'invention. En effet, le cône d'arrêt 25 doit être capable de résister thermiquement à la température élevée de la surface de la munition 11 et mécaniquement en cas d'impact violent lors d'une extraction d'une munition 11 non coincée.The stop cone 25 constitutes a major element of the reception cradle 10 according to the invention. Indeed, the stop cone 25 must be able to thermally resist the high temperature of the surface of the munition 11 and mechanically in the event of a violent impact during an extraction of an unstuck munition 11.

Le dispositif de maintien 27 du cône d'arrêt 25 comprend deux sangles latérales 31, 32 s'étendant depuis le cône d'arrêt 25 de part et d'autre du cône d'arrêt 25 jusqu'à deux points d'accroche 33, 34, un premier 33 des deux points d'accroche étant positionné sur le premier bras 21 et un second 34 des deux points d'accroche étant positionné sur le second bras 22. Le dispositif de maintien 27 comprend aussi une sangle d'attache 35 s'étendant depuis le cône d'arrêt 25 jusqu'à l'embase de fixation 15. L'ensemble formé par le cône d'arrêt 25 et les sangles latérales 31, 32 et la sangle d'attache 35 suffit à former la résistance mécanique nécessaire pour stopper la munition et la maintenir. Pour des raisons de facilité de manipulation, le cône d'arrêt 25 et les sangles sont reliés par un ensemble formant une poche.The holding device 27 of the stop cone 25 comprises two side straps 31, 32 extending from the stop cone 25 on either side of the stop cone 25 to two attachment points 33, 34, a first 33 of the two attachment points being positioned on the first arm 21 and a second 34 of the two attachment points being positioned on the second arm 22. The holding device 27 also comprises an attachment strap 35 s 'extending from the stop cone 25 to the fixing base 15. The assembly formed by the stop cone 25 and the side straps 31, 32 and the fastening strap 35 suffices to form the mechanical resistance necessary to stop the ammunition and maintain it. For reasons of ease of handling, the stop cone 25 and the straps are connected by an assembly forming a pocket.

Le cône d'arrêt 25 est défini par un cône avantageusement ouvert. Le cône est conçu de plusieurs cerclages 61 de sangles très résistantes. Ces cerclages 61 sont reliés entre eux par d'autres sangles 62 qui sont elles-mêmes reliées au sac de réception 17, par exemple par de longues coutures, avantageusement sur toute la longueur du sac de réception 17, et notamment jusqu'aux interfaces de la structure 14 afin de répartir l'effort sur un maximum de longueur lors de l'extraction. Le cône d'arrêt 25 est avantageusement ouvert de façon à ce que l'extrémité pointue et mécaniquement agressive de la fusée de la munition 11 ne provoque pas d'amorce de déchirements. L'utilisation de plusieurs cerclages additionnés permet de limiter l'effet « rebond » de la munition 11. Un tel cône d'arrêt 25, de diamètre d'extrémité légèrement inférieur à celui du corps du projectile, permet de s'affranchir d'un impact : l'arrêt du projectile est en effet assuré par le freinage dû au goulot du cône d'arrêt 25. On peut noter que le cône d'arrêt 25 est représenté avec une ouverture circulaire, semblable à la forme extérieure du corps de la munition 11. L'invention s'applique de manière similaire avec une ouverture non circulaire, mais de diamètre d'extrémité légèrement inférieur à celui du corps du projectile afin de le retenir dans le berceau de réception 10.The stop cone 25 is defined by an advantageously open cone. The cone is designed from several straps 61 of very strong straps. These straps 61 are interconnected by other straps 62 which are themselves connected to the receiving bag 17, for example by long seams, advantageously over the entire length of the receiving bag 17, and in particular to the interfaces of the structure 14 in order to distribute the force over a maximum length during the extraction. The stop cone 25 is advantageously open so that the pointed and mechanically aggressive end of the fuse of the ammunition 11 does not cause a primer. heartbreaks. The use of several straps added together makes it possible to limit the “rebound” effect of the ammunition 11. Such a stop cone 25, with an end diameter slightly smaller than that of the body of the projectile, makes it possible to dispense with an impact: the stopping of the projectile is in fact ensured by the braking due to the neck of the stop cone 25. It can be noted that the stop cone 25 is shown with a circular opening, similar to the external shape of the body of ammunition 11. The invention is applied in a similar manner with a non-circular opening, but with an end diameter slightly smaller than that of the body of the projectile in order to retain it in the receiving cradle 10.

Le sac de réception 17 (constitué des sangles et de la poche) sert, quant à lui, à récupérer le projectile une fois stoppé par le cône d'arrêt 25. La profondeur du sac de réception 17 a pour fonction de désaligner la munition 11 avec le tube 12 quelle que soit la hausse du mortier, afin d'éviter que la munition 11 ne retombe dans le tube 12. En d'autres termes, l'axe longitudinal de la munition, bien que pouvant rester sensiblement parallèle à l'axe X, est suffisamment décalé par rapport à l'axe X de sorte que la munition ne puisse plus retomber dans le tube. Le sac de réception 17, incluant poche et sangles, est avantageusement constitué de deux couches de tissus : sur le côté extérieur du sac de réception 17, une couche résistante mécaniquement et sur le côté intérieur du sac de réception 17, une couche résistante à la chaleur (au moins 100°C). Il peut s'agir par exemple de couches de tissu synthétique ignifugé.The reception bag 17 (made up of the straps and the pocket) serves, for its part, to recover the projectile once stopped by the stop cone 25. The depth of the reception bag 17 has the function of misaligning the ammunition 11 with the tube 12 regardless of the rise in the mortar, in order to prevent the ammunition 11 from falling back into the tube 12. In other words, the longitudinal axis of the ammunition, although it may remain substantially parallel to the X axis, is sufficiently offset from the X axis so that the ammunition can no longer fall back into the tube. The receiving bag 17, including pocket and straps, is advantageously made up of two layers of fabric: on the outside of the receiving bag 17, a mechanically resistant layer and on the inside of the receiving bag 17, a water-resistant layer. heat (at least 100 ° C). It may be, for example, layers of flame-retardant synthetic fabric.

Le sac de réception 17 est une pièce d'usure et est la seule interface avec la munition. Il peut être relié à la structure 14 de façon amovible afin de permettre son retrait du berceau de réception 10 en cas de détérioration du sac de réception 17.The receiving bag 17 is a wearing part and is the only interface with the ammunition. It can be connected to the structure 14 in a removable manner in order to allow its removal from the reception cradle 10 in the event of damage to the reception bag 17.

La figure 6 représente schématiquement une deuxième vue d'un sac de réception 17 du berceau de réception 10 selon l'invention. Bien qu'il puisse être formé de plusieurs pièces distinctes reliées mécaniquement entre elles, le sac de réception 17 est préférentiellement réalisé en une seule pièce. Les fixations du sac de réception 17 sur les deux bras 21, 22 du berceau de réception 10 peuvent être conçues pour permettre de retirer le sac de réception 17 sans démonter la structure 14.The figure 6 schematically shows a second view of a receiving bag 17 of the receiving cradle 10 according to the invention. Although it can be formed from several distinct parts mechanically connected to one another, the receiving bag 17 is preferably made in one piece. The attachments of the reception bag 17 on the two arms 21, 22 of the reception cradle 10 can be designed to allow the reception bag 17 to be removed without dismantling the structure 14.

Ainsi, l'extraction de la munition 11 se fait par exemple par injection d'air comprimé 13 au niveau inférieur du tube 12, avantageusement au niveau d'une soupape de sécurité préexistante du mortier, en connectant une bouteille d'air comprimé à la soupape de sécurité avec un flexible. L'air comprimé 13 pousse la munition qui est ensuite récupérée dans le berceau de réception 10. Lors de l'extraction, la munition 11 est arrêtée par la partie avant du sac de réception 17, et elle tombe au fond du sac de réception 17, comme décrit ci-dessous. Il en ressort que l'utilisateur n'intervient qu'en toute sécurité lorsque la munition est entièrement sortie du tube 12 et sans possibilité d'y retomber. De plus, comme la fusée de la munition n'est pas utilisée comme point d'accroche, comme c'est le cas avec les extracteurs à griffe de l'art antérieur, le berceau de réception selon l'invention permet l'extraction d'une munition quelle que soit la fusée utilisée. Il permet d'extraire des munitions à poste ou coincée au niveau de la bouche ou à tout niveau à l'intérieur du tube.Thus, the extraction of the ammunition 11 is done for example by injecting compressed air 13 at the lower level of the tube 12, advantageously at the level of a pre-existing safety valve of the mortar, by connecting a bottle of compressed air to the safety valve with flexible hose. The compressed air 13 pushes the ammunition which is then recovered in the reception cradle 10. During the extraction, the ammunition 11 is stopped by the front part of the reception bag 17, and it falls to the bottom of the reception bag 17 , as described below. It emerges that the user intervenes only in complete safety when the ammunition is entirely out of the tube 12 and without the possibility of falling back there. In addition, as the rocket of the ammunition is not used as an attachment point, as is the case with the claw extractors of the prior art, the receiving cradle according to the invention allows the extraction of 'ammunition regardless of the rocket used. It allows to extract ammunition at post or stuck at the muzzle or at any level inside the tube.

La figure 7 représente schématiquement la mise en place du berceau de réception 10 à l'extrémité 16 de sortie du tube 12 selon l'invention. L'embase de fixation 15 comprend un bec d'accrochage 36 sur une portion extérieure 43 de l'embase de fixation 15, destiné à coopérer avec une portion d'un collier 42 du tube 12 de sorte à permettre la rotation du berceau de réception 10 selon un deuxième axe Y, sensiblement perpendiculaire au premier axe X, lors d'une mise en place du berceau de réception 10 sur l'extrémité 16 de sortie du tube 12. Avantageusement, le collier 42 est le collier de la plaque de base appartenant au mortier, il se verrouille avec une fixation simple. Néanmoins, tout type de collier est utilisable dans la mesure où il présente une portion sur laquelle le bec d'accrochage 36 peut venir s'appuyer afin de permettre la rotation du berceau de réception 10 autour du deuxième axe Y. Le bec d'accrochage 36 facilite la mise en position du berceau de réception 10 dans l'alignement selon le premier axe X, à l'extrémité 16 de sortie du tube 12.The figure 7 schematically shows the placement of the receiving cradle 10 at the outlet end 16 of the tube 12 according to the invention. The fixing base 15 comprises a hooking spout 36 on an outer portion 43 of the fixing base 15, intended to cooperate with a portion of a collar 42 of the tube 12 so as to allow the rotation of the receiving cradle. 10 along a second Y axis, substantially perpendicular to the first X axis, when placing the receiving cradle 10 on the outlet end 16 of the tube 12. Advantageously, the collar 42 is the collar of the base plate belonging to the mortar, it locks with a simple fixing. Nevertheless, any type of collar can be used insofar as it has a portion on which the hooking spout 36 can come to rest in order to allow the rotation of the receiving cradle 10 around the second axis Y. The hooking spout 36 facilitates the positioning of the receiving cradle 10 in alignment along the first axis X, at the outlet end 16 of the tube 12.

Une fois le berceau de réception 10 placé en position à l'extrémité 16 du tube 12, il doit être verrouillé dans cette position pour y être maintenu.Once the receiving cradle 10 has been placed in position at the end 16 of the tube 12, it must be locked in this position to be held there.

La figure 8 représente schématiquement le verrouillage du berceau de réception 10 à l'extrémité 16 de sortie du tube 12 selon l'invention. Le berceau de réception 10 comprend un dispositif de verrouillage 51 apte à passer d'une configuration déverrouillée à une configuration verrouillée dans laquelle l'embase de fixation 15 est maintenue en place autour de l'extrémité 16 de sortie du tube 12, et inversement, comprenant une poignée 52 configurée pour épouser au moins partiellement la forme de l'extrémité 16 de sortie du tube 12, et un moyen de fixation 53 de la poignée 52 sur l'embase de fixation 15. Le dispositif de verrouillage 51 peut ainsi être verrouillé et déverrouillé autant de fois que nécessaire. La poignée 52 forme au moins un appui ponctuel avec le tube. Dans un mode de réalisation avantageux, le contact de la poignée 52 avec le tube 12 est un appui sensiblement plan. Dans un mode de réalisation préféré, le contact de la poignée 52 avec le tube 12 est surfacique, la poignée 52 ayant une zone 56 incurvée destinée à épouser la forme du tube 12.The figure 8 schematically shows the locking of the receiving cradle 10 at the outlet end 16 of the tube 12 according to the invention. The reception cradle 10 comprises a locking device 51 capable of moving from one unlocked configuration to a locked configuration in which the attachment base 15 is held in place around the outlet end 16 of the tube 12, and vice versa, comprising a handle 52 configured to at least partially conform to the shape of the end 16 outlet of the tube 12, and a means 53 for fixing the handle 52 on the fixing base 15. The locking device 51 can thus be locked and unlocked as many times as necessary. The handle 52 forms at least one point support with the tube. In an advantageous embodiment, the contact of the handle 52 with the tube 12 is a substantially flat support. In a preferred embodiment, the contact of the handle 52 with the tube 12 is surface, the handle 52 having a curved zone 56 intended to follow the shape of the tube 12.

Le moyen de fixation 53 peut être basique, tel qu'un ensemble vis-écrou. Dans un mode de réalisation préféré de l'invention, le moyen de fixation 53 de la poignée 52 sur l'embase de fixation 15 comprend une liaison rotule 54 et un appui plan 55. Autrement dit, le berceau de réception 10 se verrouille par le dessus du tube 12 à l'aide de la poignée 52 et le moyen de fixation 53. La poignée 52 est montée sur une rotule permettant de tourner et passer une butée mécanique (appui plan 55). De par la liaison rotule, la poignée est mobile en rotation autour d'un axe parallèle au premier axe X et autour d'un troisième axe perpendiculaire aux axes X et Y au niveau du point 54. Dans sa rotation combinée autour de ses deux axes, la poignée 52 passe sous la butée 55, par exemple une tête de vis formant un appui plan au niveau du dessous de tête, en réponse à une légère force appliquée par l'utilisateur lors de la manipulation de la poignée 52 (cela correspond à un basculement du berceau de réception 10 de l'ordre de quelques degrés). La poignée 52 comprend un épaulement destiné à former avec la tête de vis un appui faisant butée. Une fois passée cette butée mécanique 55, le berceau de réception 10 se verrouille par gravité. Plus précisément, la gravité attire le berceau de réception 10 dans le sens de la gravité. Le dessous de la tête de vis 55 est bloqué au niveau supérieur de l'épaulement de la poignée 52. Le berceau de réception 10 est alors bloqué en position à l'extrémité 16 de sortie du tube 12. En outre, avec le contact surfacique 56 de la poignée sur le tube 12, il y a hyperstaticité du berceau de réception 10, assurant un parfait maintien en position du berceau de réception 10 en sortie du tube 12.The fastening means 53 may be basic, such as a screw-nut assembly. In a preferred embodiment of the invention, the fixing means 53 of the handle 52 on the fixing base 15 comprises a ball joint 54 and a flat support 55. In other words, the receiving cradle 10 is locked by the above the tube 12 using the handle 52 and the fixing means 53. The handle 52 is mounted on a ball joint allowing a mechanical stop to be rotated and passed (plane support 55). By means of the ball joint, the handle is movable in rotation about an axis parallel to the first X axis and about a third axis perpendicular to the X and Y axes at point 54. In its combined rotation around its two axes , the handle 52 passes under the stop 55, for example a screw head forming a flat support at the level of the underside of the head, in response to a slight force applied by the user during the manipulation of the handle 52 (this corresponds to tilting of the receiving cradle 10 of the order of a few degrees). The handle 52 comprises a shoulder intended to form with the screw head a support acting as a stop. Once this mechanical stop 55 has been passed, the receiving cradle 10 locks by gravity. More precisely, gravity attracts the receiving cradle 10 in the direction of gravity. The underside of the screw head 55 is locked at the upper level of the shoulder of the handle 52. The receiving cradle 10 is then locked in position at the outlet end 16 of the tube 12. Furthermore, with the surface contact 56 of the handle on the tube 12, there is hyperstaticity of the reception cradle 10, ensuring perfect maintenance in position of the reception cradle 10 at the outlet of the tube 12.

Préalablement à l'étape de fixation 101 du berceau, le procédé peut comprendre une étape de préparation du berceau. Dans cette étape, et dans le cas de bras 21, 22 télescopiques, il convient de retirer les deux goupilles qui maintiennent les bras télescopiques en position repliée et déplier le berceau de réception en dépliant les bras télescopiques 21, 22 et le sac de réception 17. Il est nécessaire ensuite de remettre en place les goupilles pour maintenir les bras 21, 22 en position dépliée. Si nécessaire, il faut ensuite repositionner le sac de réception 17 pour ne pas entraver la sortie de la munition 11.Prior to the step 101 of fixing the cradle, the method may include a step of preparing the cradle. In this step, and in the case of telescopic arms 21, 22, it is necessary to remove the two pins which hold the telescopic arms in the folded position and unfold the reception cradle by unfolding the telescopic arms 21, 22 and the reception bag 17 It is then necessary to put the pins back in place to keep the arms 21, 22 in the unfolded position. If necessary, the receiving bag 17 must then be repositioned so as not to hinder the exit of the ammunition 11.

Après l'étape de préparation du berceau, le procédé selon l'invention peut comprendre une étape de préparation du tube. Cette étape consiste à récupérer le collier du tube et le positionner à l'extrémité de sortie du tube. Alternativement, il est possible de prendre un collier annexe au tube.After the step of preparing the cradle, the method according to the invention can comprise a step of preparing the tube. This step consists of recovering the tube collar and positioning it at the outlet end of the tube. Alternatively, it is possible to take a collar attached to the tube.

Après l'étape 104 de réception de la munition dans le sac de réception, le berceau de réception 10 peut être laissé en position sur le tube, ou il peut être démonté. Dans le cas où le procédé selon l'invention comprend une étape de démontage du berceau de réception, il convient préalablement de fermer le robinet de la source d'air comprimé. L'étape de démontage du berceau de réception comprend une étape de déverrouillage du dispositif de verrouillage pour le faire passer de la configuration verrouillée à la configuration déverrouillée. Avantageusement, l'étape de démontage comprend aussi une étape de maintien par un utilisateur du berceau de réception pour éviter un décrochage brusque. Enfin, l'étape de démontage comprend une étape de rotation du berceau de réception au niveau du bec d'accrochage autour du deuxième axe Y afin de séparer complètement le berceau du tube. Le berceau est alors réutilisable sur le même tube ou sur un autre tube.After step 104 of receiving the ammunition in the receiving bag, the receiving cradle 10 can be left in position on the tube, or it can be disassembled. In the case where the method according to the invention comprises a step of dismantling the receiving cradle, it is first necessary to close the valve of the compressed air source.

Finally, the dismantling step comprises a step of rotating the receiving cradle to the level of the hooking spout around the second Y axis in order to completely separate the cradle from the tube. The cradle is then reusable on the same tube or on another tube.

Comme il ressort de cette description, le dispositif selon l'invention et le procédé d'extraction associé permettent l'extraction par la bouche de munitions d'arme d'artillerie, avec deux caractéristiques nouvelles majeures. La totalité de l'opération d'extraction s'effectue sans danger pour les utilisateurs, car aucune étape ne nécessite de passer tout ou partie du corps devant la bouche du tube. Le berceau de réception n'est pas spécifique d'un type de munition (i.e. de la « fusée », c'est-à-dire de la pointe avant de la munition). Le procédé d'extraction selon l'invention permet d'extraire une munition d'un tube quelle que soit la position de la munition dans le tube.As emerges from this description, the device according to the invention and the associated extraction method allow the extraction by the muzzle of artillery weapon ammunition, with two major new characteristics. The entire extraction operation is carried out without danger for the users, since no step requires passing all or part of the body in front of the mouth of the tube. The receiving cradle is not specific to a type of ammunition (ie “rocket”, ie the front end of the ammunition). The extraction method according to the invention makes it possible to extract an ammunition from a tube regardless of the position of the ammunition in the tube.

La configuration du berceau de réception 10 avec son cône d'arrêt est très importante. Lors de l'étape 102 d'injection d'air comprimé dans le tube 12, il n'y a pas besoin de réguler la pression de l'air. Une fois le système pneumatique mis en place par le biais d'un flexible au niveau de la soupape du tube, il suffit d'ouvrir le robinet du système pneumatique, sans préoccupation de la pression à laquelle l'air est injecté. En d'autres termes, l'invention permet de connecter le système pneumatique au tube et d'injecter l'air comprimé à la pression maximale disponible.The configuration of the reception cradle 10 with its stop cone is very important. During the step 102 of injecting compressed air into the tube 12, there is no need to regulate the air pressure. Once the pneumatic system is in place through a hose at the tube valve, it is sufficient to open the pneumatic system valve, regardless of the pressure at which the air is injected. In other words, the invention makes it possible to connect the pneumatic system to the tube and to inject the compressed air at the maximum available pressure.

Avantageusement, le système pneumatique est autonome, et comprend une pompe pour le recharger.Advantageously, the pneumatic system is autonomous, and comprises a pump for recharging it.

Le procédé d'extraction est simple et rapide, compatible d'une utilisation dans un contexte de déploiement opérationnel (c'est-à-dire sur un théâtre d'opérations de guerre). Le berceau de réception est facilement transportable.The extraction process is simple and rapid, compatible with use in an operational deployment context (that is to say in a theater of war operations). The reception cradle is easily transportable.
