Abstract

The movable cover is for a grenade. It has an external cover (24) and an interior hollow cylindrical partition (22). This passes around the grenade body (12), which is of similar shape. The space between the outer cover and inner partition is filled with a charge (20). The charge can be an explosive, a flare, or a disabling chemical. The cover is of fragmentation metal to form shrapnel on fracture. The cover can also be made of fragments (spherical or otherwise) in a double partition or buried in a suitable material.

Description

La présente invention concerne des perfectionnements apportés aux manchons pour grenades de type modulaire. The present invention relates to improvements made to the sleeves for modular type grenades.

On connalt des grenades dont les caractéristiques vulnérantes peuvent être modifiées au moment de l'emploi, en adaptant autour du corps de grenade explosif un manchon inerte, par exemple en métal préfragmenté, dans le but de transformer une grenade offensive en grenade défensive. Pomegranates are known whose vulnérantes characteristics can be modified at the time of the use, by adapting around the body of explosive grenade an inert sleeve, for example in prfragmented metal, in order to transform an offensive grenade into defensive grenade.

Cependant, ces types de grenades ont l'inconvénient de provoquer, à l'explosion, des éclats vulnérants dont la répartition est très inégale. However, these types of grenades have the disadvantage of causing, on explosion, annoying shards whose distribution is very uneven.

La présente invention a pour but d'éviter cet inconvénient et concerne à cet effet un manchon amovible pour grenade du type susmentionné qui se-caractérise en ce qu'il comprend une enveloppe extérieure et une paroi intérieure en forme de cavité cylindrique s'adaptant autour d'un corps de grenade de forme complémentaire, l'espace compris entre l'enveloppe extérieure et la paroi intérieure étant rempli d'une charge appropriée. The present invention aims to avoid this drawback and for this purpose relates to a removable grenade sleeve of the aforementioned type which is characterized in that it comprises an outer casing and an inner wall in the form of a cylindrical cavity fitting around a grenade body of complementary shape, the space between the outer casing and the inner wall being filled with an appropriate charge.

Ladite charge peut être explosive, éblouissante ou encore à effet incapacitant. Said charge can be explosive, dazzling or even incapacitating.

L'enveloppe extérieure peut être réalisée en métal préfragmenté ou constituée d'éclats métalliques de formes appropriées (par exemple sphériques ou polyédriques) contenus dans une double paroi ou enrobés dans un matériau convenable. The outer envelope can be made of prefragmented metal or made of metal chips of appropriate shapes (for example spherical or polyhedral) contained in a double wall or coated in a suitable material.

La présence de la charge explosive permet d'améliorer la répartition des éclats vulnérants. The presence of the explosive charge improves the distribution of annoying shards.

Un mode de réalisation de l'invention sera décrit à présent à titre d'exemple non limitatif en regard de l'unique figure annexée montrant une vue en coupe d'une grenade munie d'un manchon selon l'invention. An embodiment of the invention will now be described by way of nonlimiting example with reference to the single appended figure showing a sectional view of a grenade provided with a sleeve according to the invention.

De façon connue en soi, la grenade comprend une charge explosive 10 contenue dans un corps de grenade 12 de forme générale cylindrique, un allumeur 14, un détonateur 16 et une cuiller de manoeuvre 18. In a manner known per se, the grenade comprises an explosive charge 10 contained in a grenade body 12 of generally cylindrical shape, an igniter 14, a detonator 16 and an operating spoon 18.

Autour du corps de grenade 12 est fixé un manchon amovible comprenant une charge explosive 20 remplissant l'espace compris entre une paroi interne creuse 22 de forme complémentaire de celle du corps de grenade 12 et une enveloppe 24 en métal pré fragmenté donnant des éclats vulnérants. Around the grenade body 12 is fixed a removable sleeve comprising an explosive charge 20 filling the space between a hollow internal wall 22 of a shape complementary to that of the grenade body 12 and a casing 24 of pre-fragmented metal giving offensive fragments.

La charge explosive 20 permet d'améliorer la répartition des éclats vulnérants produits par l'explosion et aussi d'augmenter la puissance explosive de la grenade. The explosive charge 20 makes it possible to improve the distribution of the annoying shards produced by the explosion and also to increase the explosive power of the grenade.

Sans sortir du cadre de l'invention, on peut aussi bien réaliser l'enveloppe 24 du manchon en une matiére ne produisant pas d'éclats vulnérants. On obtient alors une grenade offensive à effet de souffle renforcé. Without departing from the scope of the invention, it is also possible to produce the envelope 24 of the sleeve in a material which does not produce annoying splinters. We then obtain an offensive grenade with enhanced blast effect.

D'autre part, la charge explosive 20 du manchon peut également être remplacée par une composition incendiaire, ou par une composition éblouissante ou encore par une composition chimique à effet incapacitant. On the other hand, the explosive charge 20 of the sleeve can also be replaced by an incendiary composition, or by a dazzling composition or even by a chemical composition with incapacitating effect.

Il est possible également de constituer le manchon amovible en matière inerte expansée, comme cela est déjh connu par le brevet nO 2 102 563 au nom de la Demanderesse. It is also possible to form the removable sleeve of expanded inert material, as is already known from patent No. 2 102 563 in the name of the Applicant.

Un tel manchon peut être utilisé avec une grenade dont la charge est une composition pyrotechnique non détonante afin de constituer une grenade d'exercice ayant la même forme que la grenade à charge explosive. Such a sleeve can be used with a grenade, the charge of which is a non-detonating pyrotechnic composition, in order to constitute an exercise grenade having the same shape as the explosive charge grenade.
