Description

La présente invention concerne une enveloppe de protection particulièrement adaptée pour le conditionnement d'une munition à douille combustible destinée à être logée dans un container.The present invention relates to a protective envelope which is particularly suitable for packaging ammunition with a combustible case intended to be housed in a container.

Les munitions à douille combustible exigent des précautions particulières en ce qui concerne leur conditionnement en vue de leur transport et de leur stockage. En effet, il convient non seulement de protéger efficacement la douille de telles munitions qui est une partie plus délicate que la douille d'une munition classique mais encore d'empêcher la pénétration de la partie projectile dans la douille par inertie, par exemple, dans le cas d'un choc axial exercé sur l'avant ou sur l'arrière de la munition.Ammunition with combustible casings requires special precautions with regard to their packaging for transport and storage. Indeed, it is advisable not only to effectively protect the shell from such ammunition which is a more delicate part than the shell of a conventional ammunition but also to prevent the penetration of the projectile part into the shell by inertia, for example in the case of an axial shock exerted on the front or on the rear of the ammunition.

Dans le brevet belge 887 840, on a déjà décrit un emballage particulier convenant pour le conditionnement de douilles combustibles qui implique le recours à une feuille tubulaire de papier kraft éventuellement armé disposé autour de la douille. Ce type d'emballage protège efficacement la douille conditionnée contre des chocs latéraux mais il ne peut convenir pour l'emballage de munition comportant non seulement une douille combustible mais encore une partie projectile de masse relative élevée raccordée à la douille.In the Belgian patent 887 840, a particular packaging has already been described which is suitable for the packaging of combustible sockets which involves the use of a tubular sheet of kraft paper possibly reinforced, arranged around the socket. This type of packaging effectively protects the packaged case against side impact, but it is not suitable for ammunition packaging comprising not only a combustible case but also a projectile part of high relative mass connected to the case.

Dans la demande de brevet français 2 477 697, on a également décrit un conditionnement pour obus à douille impliquant le recours à deux demi-coquilles moulées, par exemple, en polyuréthane dont la surface intérieure épouse les surfaces extérieures de la partie antérieure de la douille et de la partie postérieure de la partie galbée de moindre diamètre de l'obus et à une portion de tube qui entoure uniquement les demi-coquilles et assure leur assemblage. Un tel conditionnement ne peut convenir pour emballer avec sécurité une munition à douille combustible car il ne protégerait pas une telle munition contre les effets fâcheux qui pourraient résulter d'un choc axial exercé sur ses extrémités.In French patent application 2 477 697, packaging for a shell shell has also been described, involving the use of two molded half-shells, for example, made of polyurethane, the inner surface of which matches the exterior surfaces of the front part of the sleeve. and of the posterior part of the curved part of smaller diameter of the shell and to a portion of tube which surrounds only the half-shells and ensures their assembly. Such packaging is not suitable for securely packaging a munition with a combustible case because it would not protect such ammunition against untoward effects which could result from an axial shock exerted on its ends.

La présente invention a pour objet de fournir une enveloppe de protection pour munition à douille combustible qui protège celle-ci contre n'importe quel type de choc.The object of the present invention is to provide a protective casing for ammunition with a combustible casing which protects the latter against any type of impact.

Elle concerne, dès lors, une enveloppe de protection pour munition à douille combustible comportant deux demi-coquilles en matière thermoplastique expansée assemblées autour de la partie projectile de la munition, les demi-coquilles assemblées ayant un diamètre externe au maximum sensiblement égal au diamètre externe de la douille combustible et étant profilées de façon à s'accrocher sur des points d'appui présents ou prévus sur la partie projectile et dans laquelle les demi-coquilles sont maintenues assemblées par un tube de protection rigide enfilé sur celles-ci et sur la totalité de la douille combustible qui se caractérise en ce qu'elle comporte un moyen de verrouillage mécanique entre les demi-coquilles assemblées et le tube de protection empêchant tout déplacement axial relatif entre ces éléments.It therefore relates to a protective casing for ammunition with combustible casing comprising two half-shells of expanded thermoplastic material assembled around the projectile part of the ammunition, the assembled half-shells having an external diameter at most substantially equal to the external diameter of the combustible case and being profiled so as to hang on support points present or provided on the projectile part and in which the half-shells are held assembled by a rigid protective tube threaded thereon and on the whole of the combustible socket which is characterized in that it comprises a mechanical locking means between the assembled half-shells and the protective tube preventing any relative axial movement between these elements.

L'enveloppe conforme à l'invention assure une protection efficace de la douille combustible et de la partie projectile contre des chocs latéraux par l'intermédiaire du tube de protection ou de l'ensemble tube de protection - demi-coquilles contre des chocs axiaux par la solidarisation assurée entre les demi-coquilles assemblées et le tube de protection rigide.The envelope according to the invention provides effective protection of the combustible case and of the projectile part against lateral impacts by means of the protective tube or of the protective tube - half-shell assembly against axial impacts by the secured connection between the assembled half-shells and the rigid protective tube.

Le moyen de verrouillage peut être quelconque pour autant qu'il empêche efficacement tout déplacement axial relatif entre les demi-coquilles assemblées et le tube de protection sous l'effet de contraintes extérieures. Toutefois, selon un mode de réalisation qui est préféré, le moyen de verrouillage est constitué par au moins un anneau ou une bague élastique entourant au moins partiellement le tube de protection et équipé, sur sa face interne, de protubérances qui bloquent axialement les demi-coquilles assemblées au travers d'ouvertures prévues dans la paroi du tube protecteur. Afin de parfaire ce blocage, il est utile de prévoir des logements appropriés dans la face externe des demi-coquilles assemblées et destinés à recevoir l'extrémité des protubérances prévues sur la face interne de l'anneau élastique. L'anneau élastique assurant le verrouillage mécanique entre le tube de protection et les demi-coquilles assemblées peut être réalisée en tout matériau adéquat et notamment en matière plastique ou en métal.The locking means can be arbitrary as long as it effectively prevents any relative axial displacement between the assembled half-shells and the protective tube under the effect of external stresses. However, according to a preferred embodiment, the locking means is constituted by at least one ring or an elastic ring at least partially surrounding the protection tube and equipped, on its internal face, with protuberances which axially block the half-pieces. shells assembled through openings provided in the wall of the protective tube. In order to perfect this blocking, it is useful to provide suitable housings in the external face of the assembled half-shells and intended to receive the end of the protuberances provided on the internal face of the elastic ring. The elastic ring ensuring mechanical locking between the protective tube and the assembled half-shells can be made of any suitable material, in particular plastic or metal.

Les demi-coquilles sont généralement symétriques et présentent un profil interne qui s'adapte au profil externe de la partie projectile. En outre, les demi-coquilles doivent être conçues de façon telle que leur profil interne présente des points d'accrochage avec des points d'appui présents sur la partie projectile de sorte qu'après assemblage ces demi-coquilles ne puissent se déplacer axialement par rapport à la partie projectile, celle-ci étant bloquée dans les demi-coquilles. Dans le cas où la partie projectile ne présente pas des points d'appui suffisants pour assurer un tel blocage, on peut équiper la partie projectile d'inserts métalliques ou autres fixés sur la partie projectile de façon à obtenir des points d'appui appropriés.The half-shells are generally symmetrical and have an internal profile which adapts to the external profile of the projectile part. In addition, the half-shells must be designed in such a way that their internal profile has hooking points with support points present on the projectile part so that after assembly these half-shells cannot be moved axially by relative to the projectile part, the latter being blocked in the half-shells. In the case where the projectile part does not have sufficient support points to ensure such blocking, it is possible to equip the projectile part with metallic or other inserts fixed to the projectile part so as to obtain appropriate support points.

Les deux demi-coquilles peuvent avantageusement présenter des systèmes d'accrochage tels que des logements et protubérance complémentaires sur leurs faces en contact lors de leur assemblage de façon à faciliter un positionnement correct de ces demi-coquilles autour de la partie projectile et à parfaire leur assemblage.The two half-shells can advantageously have attachment systems such as housings and complementary protuberance on their faces in contact during their assembly so as to facilitate correct positioning of these half-shells around the projectile part and to perfect their assembly.

Les demi-coquilles sont généralement réalisées par moulage et notamment par moulage par injection à partir d'une matière thermoplastique expansible telle qu'une résine oléfinique, une résine styrénique ou une résine de polyuréthane. En général, on préfère utiliser une résine de polyuréthane de qualité injectable. La résine expansible choisie doit présenter une résistance mécanique, une rigidité et une résistance à l'abrasion suffisante pour permettre aux demi-coquilles moulées d'assurer leur fonction de blocage de la partie projectile de la munition.The half-shells are generally produced by molding and in particular by injection molding from an expandable thermoplastic material such as an olefinic resin, a styrenic resin or a polyurethane resin. In general, it is preferred to use an injectable quality polyurethane resin. The expandable resin chosen must have sufficient mechanical strength, rigidity and abrasion resistance to allow the molded half-shells to perform their function of blocking the projectile part of the ammunition.

Ainsi qu'il a été dit ci-avant, il peut être avantageux de prévoir sur la face externe des demi-coquilles des moyens tels que des logements dans lesquels peuvent venir ultérieurement se bloquer les protubérances prévues sur la face interne de la bague élastique et ce, afin d'obtenir un verrouillage mécanique parfait entre le tube de protection rigide et les demi-coquilles assemblées.As has been said above, it may be advantageous to provide on the external face of the half-shells means such as housings in which the protuberances provided on the internal face of the elastic ring can come to lock later and this, in order to obtain perfect mechanical locking between the rigid protective tube and the assembled half-shells.

Enfin, les demi-coquilles assemblées doivent présenter sur leur face externe des points d'appui sur le tube de protection répartis sur toute leur longueur.Finally, the assembled half-shells must have support points on the protective tube on their outer face distributed over their entire length.

Le tube de protection rigide dont le diamètre interne est sensiblement égal au diamètre externe de la douille combustible doit présenter une résistance aux chocs et une résistance à la flexion suffisante pour garantir la protection de la munition. Ce tube s'étend sur toute la longueur de la munition sur laquelle il est enfilé après mise en place des demi-coquilles autour de la partie projectile de la munition.The rigid protective tube whose internal diameter is substantially equal to the external diameter of the combustible case must have an impact resistance and sufficient bending resistance to guarantee protection of the ammunition. This tube extends over the entire length of the ammunition on which it is threaded after placing half-shells around the projectile part of the ammunition.

Le tube de protection rigide peut avantageusement être réalisé à partir de matériaux tels que le papier, le carton, les matières plastiques et les métaux. Il peut être produit pour cintrage, par enroulement, par extrusion, etc.The rigid protective tube can advantageously be made from materials such as paper, cardboard, plastics and metals. It can be produced for bending, winding, extrusion, etc.

Il est avantageux de concevoir et de disposer le tube de protection de façon telle qu'une de ses extrémités prenne appui sur le rebord du culot de la douille combustible.It is advantageous to design and arrange the protective tube in such a way that one of its ends bears on the edge of the base of the combustible socket.

Enfin, il convient de prévoir des ouvertures adéquates dans la paroi du tube de protection de façon à permettre son verrouillage avec les demi-coquilles assemblées par la mise en place de l'anneau élastique.Finally, it is necessary to provide adequate openings in the wall of the protective tube so as to allow its locking with the half-shells assembled by the positioning of the elastic ring.

La munition à douille combustible équipée de l'enveloppe de protection conforme à l'invention peut avantageusement être placée dans un container de suremballage en vue de son transport et de son stockage. Un tel container est par exemple décrit dans la demande de brevet français 2 317 625.The ammunition with combustible casing equipped with the protective envelope according to the invention can advantageously be placed in an overpacking container for transport and storage. Such a container is for example described in French patent application 2 317 625.

L'enveloppe de protection peut toutefois être utilisée seule lors du stockage des munitions à douille combustible.The protective envelope can however be used alone when storing ammunition with combustible casings.

L'enveloppe de protection conforme à l'invention est, en outre, illustrée plus en détail dans la description qui va suivre d'un mode de réalisation particulier. Dans cette description, on se référera aux figures des dessins annexés dans lesquelles :

  • la fig.l est une vue en élévation et en coupe partielle d'une enveloppe de protection conforme à l'invention
  • la fig.2 est une vue en coupe suivant l'axe AA' de la fig.l.
The protective envelope according to the invention is, moreover, illustrated in more detail in the description which follows of a particular embodiment. In this description, reference will be made to the figures of the appended drawings in which:
  • Fig.l is an elevational view in partial section of a protective envelope according to the invention
  • Fig.2 is a sectional view along the axis AA 'of Fig.l.

Ainsi qu'il apparaît aux figures, l'enveloppe de protection pour une munition comportant une douille combustible 1 et une partie projectile 2 est constituée de deux demi-coquilles assemblées 3, 4 en matière thermoplastique expansée, d'un tube de protection rigide 5 et d'une bague élastique 6 assurant le verrouillage mécanique entre les demi-coquilles assemblées 3, 4 et le tube de protection rigide 5.As shown in the figures, the protective casing for a munition comprising a combustible case 1 and a projectile part 2 consists of two assembled half-shells 3, 4 made of expanded thermoplastic material, of a rigid protective tube 5 and an elastic ring 6 ensuring mechanical locking between the assembled half-shells 3, 4 and the rigid protective tube 5.

Les demi-coquilles assemblées 3, 4 présentent un profil interne qui s'adapte au profil externe de la partie projectile 2 et comporte des points d'accrochage 7, 8, 9 avec des points d'appui de la partie projectile qui assurent un blocage axial entre les demi-coquilles assemblées 3, 4 et la parte projectile 2. Les demi-coquilles assemblées 3, 4 présentent un diamètre externe au maximum égal au diamètre externe de la douille et sont pourvues sur leur face externe de points d'appui 10, 11, 12, 13 sur le tube de protection rigide 5 enfilé sur les coquilles assemblées.The assembled half-shells 3, 4 have an internal profile which adapts to the external profile of the projectile part 2 and includes attachment points 7, 8, 9 with support points of the projectile part which ensure blocking axial between the assembled half-shells 3, 4 and the projectile part 2. The assembled half-shells 3, 4 have an external diameter at most equal to the external diameter of the sleeve and are provided on their external face with support points 10 , 11, 12, 13 on the rigid protective tube 5 threaded onto the assembled shells.

Le tube de protection rigide 5 de diamètre interne sensiblement égal au diamètre externe de la douille combustible 1 est réalisé en carton par exemple par enroulement.The rigid protective tube 5 of internal diameter substantially equal to the external diameter of the combustible sleeve 1 is made of cardboard, for example by winding.

Le tube de protection rigide 5 s'étend sur pratiquement toute la longueur de la munition. Ce tube de protection 5, enfilé sur la douille combustible 1 et sur les demi-coquilles assemblées 3, 4, prend appui par son extrémité sur le culot 14 de la douille combustible 1. En outre, la paroi interne du tube de protection 5 prend appui sur les cloisons des points d'appui 10, 11, 12, 13 prévues sur la face externe des demi-coquilles assemblées 3, 4.The rigid protective tube 5 extends over practically the entire length of the munition. This protective tube 5, threaded on the combustible sleeve 1 and on the assembled half-shells 3, 4, bears at its end on the base 14 of the combustible sleeve 1. In addition, the internal wall of the protective tube 5 takes support on the partitions of the support points 10, 11, 12, 13 provided on the external face of the assembled half-shells 3, 4.

Le verrouillage mécanique empêchant tout déplacement axial relatif entre les demi-coquilles assemblées 3, 4 et le tube de protection rigide 5 est assuré par une bague élastique 6 entourant partiellement le tube de protection rigide 5 et équipée sur sa face interne de protubérances 15 qui bloquent axialement les demi-coquilles assemblées 3, 4, au travers d'ouvertures 16 prévues dans la paroi du tube de protection rigide 5. En outre, ainsi qu'il apparaft à la fig.1, les cloisons des points d'appui 11, 12 prévues sur la face externe des demi-coquilles assemblées 3, 4 déterminent un logement 17 pouvant recevoir les protubérances 15 prévues sur la bague élastique 6 de façon à parfaire le blocage axial des demi-coquilles.The mechanical locking preventing any relative axial displacement between the assembled half-shells 3, 4 and the rigid protection tube 5 is ensured by an elastic ring 6 partially surrounding the rigid protection tube 5 and equipped on its internal face with protuberances 15 which block axially the assembled half-shells 3, 4, through openings 16 provided in the wall of the rigid protective tube 5. In addition, as shown in FIG. 1, the partitions of the support points 11, 12 planned on the external face of the assembled half-shells 3, 4 determine a housing 17 which can receive the protuberances 15 provided on the elastic ring 6 so as to perfect the axial blocking of the half-shells.

Pour conditionner la munition dans l'enveloppe de protection sus décrite, il suffit d'assembler les deux demi-coquilles 3, 4 autour de la partie projectile 2 de la munition, puis d'enfiler le tube de protection rigide 5 sur les demi-coquilles assemblées 3, 4 et sur la douille combustible 1 de façon telle que l'extrémité du tube de protection vienne buter contre le rebord du culot 14 de la douille 1 et enfin de procéder à la mise en place de la bague élastique 6. Il en résulte que la bague élastique 6 assure un verrouillage entre le tube de protection 5 et les demi-coquilles assemblées 3, 4 empêchant tout déplacement axial relatif entre ces éléments 3, 4 et 5 et partant tout déplacement axial relatif entre la douille combustible 1 et la partie projectile 2 de la munition sous l'effet d'un choc éventuellement exercé sur les extrémités de l'enveloppe de protection.To condition the ammunition in the above-described protective envelope, it suffices to assemble the two half-shells 3, 4 around the projectile part 2 of the ammunition, then to thread the rigid protective tube 5 onto the half shells assembled 3, 4 and on the combustible socket 1 so that the end of the protective tube comes to abut against the edge of the base 14 of the socket 1 and finally to proceed with the positioning of the elastic ring 6. It as a result that the elastic ring 6 ensures a locking between the protective tube 5 and the assembled half-shells 3, 4 preventing any relative axial displacement between these elements 3, 4 and 5 and therefore any relative axial displacement between the combustible bush 1 and the projectile part 2 of the ammunition under the effect of a shock possibly exerted on the ends of the protective envelope.

Bien que l'enveloppe de protection sus décrite convient particulièrement pour le conditionnement des munitions à douille combustible, il est bien évident que cette enveloppe de protection peut également être exploitée pour le conditionnement de munition classique à douille non combustible.Although the above-described protective envelope is particularly suitable for packaging ammunition with combustible casing, it is obvious that this protective envelope can also be used for packaging conventional ammunition with non-combustible cartridge case.
