Abstract

The sporting gun casing is made of fitted sheet parts and is not machined from the solid. It consists of two shells, fitted together, and the external faces are smooth. Each shell has sheet reinforcing plates to give rigidity. The reinforcing plates also act as guides to help in fitting the two shells together. The shells are fixed by electron beam welding along their upper edges. The reinforcing plates are also shaped to match parts inside, such as a sliding breech.

Description

       

  "Carcasse pour fusil de chasse" La présente invention concerne une carcasse pour fusil de chasse.

  
Jusqu'à présent, les carcasses de fusils de chasse ont été usinées hors masse, ce qui est particulièrement onéreux. Pour les armes de guerre par contre, on a déjà réalisé de carcasses en tôle emboutie. Toutefois l'aspect de telles pièces est incompatible avec les exigences esthétiques de la grande majorité des tireurs de sport et des chasseurs.

  
Le but de la présente invention est de permettre une fabrication par emboutissage ne présentant pas le désavantage de la technique connue, tout en donnant une carcasse parfaitement rigide malgré un aspect extérieur tout à fait comparable à celui des carcasses classiques.

  
Ce but est atteint, conformément à l'invention, par assemblage de deux coquilles dont les faces externes sont lisses, leur faces internes étant préalablement pourvues chacune d'une tôle

  
de renforcement profilée également emboutie, les profilages desdites tôles servant en outre au support et au guidage des pièces usuelles destinées à occuper l'intérieur de la carcasse.

  
Un exemple de réalisation de l'invention est décrit ci-après à titre illustratif et non restrictif, référence étant faite aux dessins annexés, dans lesquels :
la figure 1 est une vue partielle schématique d'un fusil de chasse automatique; la figure 2 est une vue explosée de la carcasse du fusil de la figure 1, et les figures 3 et 4 sont des coupes respectivement selon les lignes III-III et IV-IV de la figure 1.

  
A la figure 1, on reconnait la carcasse 1 prolongeant la crosse 2, le canon 3, le garde-main 4 et la sous-garde 5.

  
La carcasse 1 est constituée de deux coquilles 6 et 7 en tôle emboutie et dont les faces externes et internes sont lisses.

  
Aux faces internes desdites coquilles sont assujetties des tôles de renforcement profilées, respectivement 8 et 9, puis les deux coquilles sont réunies par exemple par soudure au faisceau d'électrons de leurs bords supérieurs, comme indiqué en 10.

  
Le profilage des tôles 8 et 9 est réalisé de façon à fournir



  The present invention relates to a carcass for a shotgun.

  
So far, shotgun carcasses have been machined out of the mass, which is particularly expensive. For weapons of war, on the other hand, we have already made stamped sheet metal carcasses. However, the appearance of such parts is incompatible with the aesthetic requirements of the vast majority of sport shooters and hunters.

  
The object of the present invention is to allow production by stamping which does not have the disadvantage of the known technique, while giving a perfectly rigid carcass despite an external appearance quite comparable to that of conventional carcasses.

  
This object is achieved, in accordance with the invention, by assembling two shells whose external faces are smooth, their internal faces being previously provided each with a sheet

  
profiled reinforcement also stamped, the profiling of said sheets further serving to support and guide the usual parts intended to occupy the interior of the carcass.

  
An exemplary embodiment of the invention is described below by way of illustration and without limitation, reference being made to the appended drawings, in which:
Figure 1 is a schematic partial view of an automatic shotgun; FIG. 2 is an exploded view of the carcass of the rifle of FIG. 1, and FIGS. 3 and 4 are sections respectively along lines III-III and IV-IV of FIG. 1.

  
In FIG. 1, we recognize the carcass 1 extending the butt 2, the barrel 3, the handguard 4 and the subguard 5.

  
The carcass 1 consists of two shells 6 and 7 made of stamped sheet metal and whose external and internal faces are smooth.

  
The internal faces of said shells are subject to profiled reinforcing sheets, respectively 8 and 9, then the two shells are joined for example by electron beam welding of their upper edges, as indicated in 10.

  
The profiling of the sheets 8 and 9 is carried out so as to provide

Claims

the bearing and guiding surfaces required by the parts to occupy the interior of the carcass, such as movable yoke, retainers, etc. The above-described construction method results in a light, rigid carcass whose aesthetic is practically identical to that of a conventional carcass. Compared to the latter, manufacturing times are considerably reduced and therefore also the cost. It is obvious that many modifications can be made to the example described above depending on the type of weapon envisaged, its arming and ejection mechanism, etc. CLAIMS.

1.- Carcass for a shotgun characterized in that it is constituted by the assembly of two shells whose external faces are smooth, their internal faces being previously provided each with a profiled reinforcing sheet also stamped, the profiling of said sheets also used to support and guide the usual parts intended to occupy the interior of the carcass.

2.- Hunting rifle casing, substantially as described above and illustrated in the accompanying drawings.
