BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to an improvement applied to individual firearms of the kind having a pivoting magazine, and it provides a device that makes it possible to ensure that the pivoting magazines of semi-automatic hunting rifles, in particular, incapable of being removed from the firearm.
The technical field of the invention is that of manufacturing firearms.
BACKGROUND OF THE INVENTION
Traditionally, most long-barrelled firearms (for shooting from the shoulder) that operate semi-automatically, whether by central percussion or by annular percussion, posses a cartridge magazine also called a magazine case or a charger that is substantially in the form of a parallelepiped, and that engages in a housing in the firearm as is normally situated beneath the breech and is referred to as the magazine well.
The inside dimensions of the magazine well are very close to the dimensions of the magazine case, to ensure that there is little play between the magazine and its housing. This means that the magazine can be inserted or extracted solely by a movement in linear translation through the open bottom of the magazine well.
This type of magazine is generally held in place by a latch carried by the magazine well (or by the breech casing) co-operating with a notch or a recess or a projection on the magazine so as to lock it in the firearm operating position.
With some firearms, the magazine carries the latch and the firearm carries the fastener element that co-operate with the latch.
This type of magazine case is usually constituted by a sheet steel box in which there slides in the vertical direction (down and up) a part whose shape is substantially complementary to the shape (inside section) of the magazine, and which is urged towards the open end of the magazine by a spring, i.e. towards the top of the magazine.
This part, referred to as a lift or lift plate or platform, serves to support the stack of cartridges and to urge the cartridges towards the top of the magazine each time one of them is inserted into the firing chamber.
The number of cartridges that such a magazine case can contain is a function of the distance that the lift can travel downwards into the magazine while compressing the spring, and prior to encountering an abutment that prevents further movement of the lift. The abutment is generally constituted by a projection carried by the walls of the magazine or is merely constituted by the spring reaching maximum compression.
Also, patent BE A 670 534 (FABRIQUE NATIONALE D'ARMES DE GUERRE) discloses a firearm that includes a pivotally mounted magazine. The inside wall of the breech casing of the firearm posses a loading orifice in front of the trigger through which orifice cartridges are fed in succession from a removable magazine. The magazine is carried by a support element that is tiltably mounted relative to the breech casing and that is held by a manually-actuatable retaining element. The magazine support is hinged relative to the firearm about a pivot situated beneath the handguard, in front of the magazine well, and fitted with a spring.
SUMMARY OF THE INVENTION
The problem posed consists in providing a firearm fitted with a non-removable pivoting magazine that can contain no more than some predetermined number of cartridges (e.g. two). A problem that is posed also consists in providing a firearm whose pivoting magazine cannot be replaced by another magazine.
A problem posed also consists in providing a device that makes it possible to ensure that the pivoting magazines are not removable.
The solution to the problem posed consists in providing an individual firearm having a magazine-forming case that is pivotally mounted about a transverse axis XX (which is substantially horizontal when the firearm is in its position of use, and perpendicular to the longitudinal axis YY of the firearm barrel) on a pin extending along said transverse axis XX and forming a pivot; the firearm includes a breech casing having a magazine well whose general shape is substantially parall
