Abstract

The practice round has the inner chamber (4) of its cartridge case (1) with a reduced diameter, by having its outer wall thickened with a layer of resin. The volume of the chamber can also be reduced lengthwise, by having an elongated percussion element between the base (9) of the case and the primer (6), or by having an elongated axial rod between the explosive (5) and the projectile (2).

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

L'invention est du domaine de l'armement. Elle a pour objet une munition pour la pratique du tir d'exercice et/ou du tir sportif, avec une arme individuelle à tir réel.  The invention is in the field of armaments. Its purpose is ammunition for the practice of practice shooting and / or sport shooting, with an individual live-fire weapon.

On rappelle qu'une munition comprend principalement un étui, ou douille, logeant dans une chambre interne une réserve d'explosif, et au moins un projectile, dit aussi balle. Cette réserve d'explosif est en contact avec la face postérieure d'un projectile, balle notamment ou analogue telle que seringue. Ce projectile est supporté par l'étui à son extrémité antérieure qu'il prolonge axialement. La réserve d'explosif est aussi en contact avec une amorce située à l'extrémité postérieure de l'étui, cette amorce étant prévue pour être heurtée par le percuteur de l'arme. On comprendra donc que la munition comprend principalement l'étui délimitant un volume intérieur formant une chambre de réception d'une réserve d'explosif, cet étui recevant une suite d'éléments pour le fonctionnement en chaîne de la munition, depuis son extrémité postérieure vers son extrémité antérieure. Cette suite d'éléments comprend notamment l'amorce, la réserve d'explosif et le projectile.  Recall that an ammunition mainly comprises a case, or case, housing in an internal chamber a reserve of explosive, and at least one projectile, also called bullet. This explosive reserve is in contact with the rear face of a projectile, in particular a bullet or the like such as a syringe. This projectile is supported by the case at its anterior end which it extends axially. The explosive reserve is also in contact with a primer located at the rear end of the holster, this primer being intended to be struck by the striker of the weapon. It will therefore be understood that the munition mainly comprises the case delimiting an interior volume forming a chamber for receiving an explosive reserve, this case receiving a series of elements for the chain operation of the ammunition, from its rear end towards its anterior end. This series of elements notably includes the primer, the explosive reserve and the projectile.

L'étui, de conformation générale cylindrique effilée à son extrémité antérieure, est habituellement formé d'un fût en laiton de faible épaisseur, pour optimiser le volume de la chambre de réception de l'explosif au regard de l'encombrement global de la munition. C'est pourquoi, un problème posé réside dans l'utilisation d'une arme agencée pour recevoir une munition à tir réel, pour la pratique du tir d'exercice et/ou du tir sportif. Dans ce cas, il est nécessaire de réduire la quantité d'explosif contenu dans la chambre interne de l'étui. Pour cela, il est habituel de compenser le volume manquant d'explosif par un matériau inerte de substitution.  The case, of generally cylindrical conformation tapered at its anterior end, is usually formed of a thin brass barrel, to optimize the volume of the explosive receiving chamber with regard to the overall size of the ammunition . This is why, a problem posed lies in the use of a weapon arranged to receive a live-fire ammunition, for the practice of practice shooting and / or sport shooting. In this case, it is necessary to reduce the amount of explosive contained in the internal chamber of the case. For this, it is usual to compensate for the missing volume of explosive with an inert substitute material.

Le but de la présente invention est de proposer une munition pour la pratique du tir d'exercice et/ou du tir sportif, avec une arme individuelle à tir réel.  The object of the present invention is to provide ammunition for the practice of practice shooting and / or sport shooting, with an individual live-fire weapon.

La présente invention va être décrite en relation avec les figures de la planche annexée, dans laquelle planche :  The present invention will be described in relation to the figures of the appended plate, in which plate:

<Desc/Clms Page number 2><Desc / Clms Page number 2>

la fig. 1 est une vue schématique d'une munition de l'art antérieur, les fig. 2, fig. 3, fig. 4 et fig. 5 représentent schématiquement des munitions selon diverses variantes respectives et préférées de réalisation de l'invention.  fig. 1 is a schematic view of a munition of the prior art, FIGS. 2, fig. 3, fig. 4 and fig. 5 schematically represent ammunition according to various respective and preferred embodiments of the invention.

Sur la fig. 1, une munition de l'art antérieur comprend un étui 1 qui : a) supporte un projectile 2 à son extrémité antérieure 3, b) délimite un volume intérieur formant une chambre 4 de réception d'un explosif 5, c) supporte une amorce 6 à son extrémité antérieure 7.  In fig. 1, a munition of the prior art comprises a case 1 which: a) supports a projectile 2 at its anterior end 3, b) defines an interior volume forming a chamber 4 for receiving an explosive 5, c) supports a primer 6 at its anterior end 7.

On remarquera que la paroi de l'étui 1, en laiton, est une paroi fine ménageant une chambre interne 4 d'un volume sensiblement équivalent à celui global extérieur de l'étui 1. On notera aussi que la suite d'éléments participant du fonctionnement habituel en chaîne de la munition comprend successivement l'amorce 6, l'explosif 5 et le projectile 2.  It will be noted that the wall of the case 1, made of brass, is a thin wall providing an internal chamber 4 of a volume substantially equivalent to that of the overall exterior of the case 1. It will also be noted that the series of elements participating in the usual chain operation of the ammunition successively comprises the primer 6, the explosive 5 and the projectile 2.

Sur les fig. 2 à fig. 5, diverses variantes de la présente invention sont schématiquement illustrées, dont la démarche générale a consisté dans à rompre les habitudes prises dans le domaine, et à réduire le volume de la chambre interne 4 de l'étui 1.  In fig. 2 to fig. 5, various variants of the present invention are schematically illustrated, the general approach of which consisted in breaking the habits adopted in the field, and in reducing the volume of the internal chamber 4 of the case 1.

Sur la fig. 2, cette réduction de volume est effectuée au moins diamétralement, notamment par un accroissement de l'épaisseur e de l'étui 1, qui est alors avantageusement formé d'une masse évidée de résine. Ces dispositions confèrent à la chambre 4 une dimension transversale D1 au plus de l'ordre de celle D2 de la face postérieure du projectile 2. On comprendra que l'évidemment de la masse en résine formant l'étui 1 forme la chambre 4 de réception de l'explosif.  In fig. 2, this reduction in volume is carried out at least diametrically, in particular by increasing the thickness e of the case 1, which is then advantageously formed from a hollowed-out mass of resin. These provisions give the chamber 4 a transverse dimension D1 at most of the order of that D2 of the rear face of the projectile 2. It will be understood that obviously the mass of resin forming the case 1 forms the receiving chamber 4 explosive.

Sur les fig. 3 à fig. 5, la réduction du volume de la chambre interne 4 de l'étui 1 est aussi de préférence une réduction de dimension longitudinale. Celle-ci est compensée par l'interposition entre deux quelconques au moins des éléments 6,5, 2, rendus distants, qui participent de la suite  In fig. 3 to fig. 5, the reduction in the volume of the internal chamber 4 of the case 1 is also preferably a reduction in longitudinal dimension. This is offset by the interposition between any two at least elements 6, 5, 2, made distant, which participate in the sequence

<Desc/Clms Page number 3><Desc / Clms Page number 3>

d'éléments pour le fonctionnement en chaîne de la munition, de moyens de mise en relation positive entre ces deux éléments distants.  elements for the chain operation of the ammunition, means for positive connection between these two distant elements.

Par exemple sur la fig. 3, les moyens de mise en relation sont constitués par un percuteur annexe 8 interposé entre l'amorce 6 et la face d'extrémité postérieure 9 de la munition, contre laquelle est prévue d'être appliqué le choc du percuteur de l'arme.  For example in fig. 3, the connecting means are constituted by an auxiliary striker 8 interposed between the primer 6 and the rear end face 9 of the ammunition, against which the impact of the striker of the weapon is intended to be applied.

Par exemple encore sur la fig. 4, les moyens de mise en relation sont constitués par la chambre interne 4 de l'étui 1, celle-ci constituant non seulement une chambre de réception de l'explosif 5, mais aussi une chambre de réception du projectile 2 à l'intérieur de l'étui 1.  For example again in fig. 4, the connecting means are constituted by the internal chamber 4 of the case 1, this constituting not only a chamber for receiving the explosive 5, but also a chamber for receiving the projectile 2 inside from case 1.

Par exemple encore et enfin sur la fig. 5, les moyens de mise en relation sont constitués par un organe 10 à extension axiale prolongeant la face postérieure du projectile 2 vers la réserve d'explosif 5. For example again and finally in fig. 5, the connecting means are constituted by a member 10 with axial extension extending the rear face of the projectile 2 towards the explosive reserve 5.
