Definitions

• the present invention relates to an improvement made to individual firearms equipped with a pivoting magazine and provides a device making it possible to make the pivoting magazines of semi-automatic hunting rifles in particular irremovable from
• the technical field of the invention is that of the manufacture of firearms.
• most long guns (or long guns) with semi-automatic operation whether central percussion or annular percussion, have a cartridge magazine also called magazine-magazine or magazine, of substantially parallelepiped shape, which fits into a housing for the weapon normally located below the breech and called magazine magazine.
• This magazine well has internal dimensions very close to the dimensions of the magazine or magazine box, so that there is little play between the magazine and its housing; this only allows the magazine or magazine to be put in place or removed only by a linear translational movement passing through the lower end of the magazine well which is open.
• This type of charger is generally retained in place by a latch carried by the charger well (or by the cylinder head housing) which cooperates with a notch or a housing or a projection carried by the magazine in order to lock it in the operating position. of the weapon.
• This type of charger box usually consists of a sheet steel box in which slides in the direction of the height (from top to bottom and from bottom to top), a part whose shape substantially matches the shape (the internal section) of the charger, which is pushed towards the open end of the charger by a spring, that is to say towards the upper part of the charger.
• This part called elevator or elevating board or elevating plate is intended to carry the stacked cartridges and to push them towards the top of the casing-charger, progressively that they are introduced into the chamber of the weapon.
• the number of cartridges that such a charger box can contain is a function of the distance that this lifting board can travel down inside the charger, compressing the spring, before encountering a stop that prevents a subsequent movement of the lifting plate; this stop is generally constituted by a projection carried by the walls of the charger or simply constituted by the spring having reached its maximum compression.
• the problem posed consists in procuring a firearm equipped with a revolving pivoting magazine which cannot contain more than a predetermined number of cartridges (for example 2); a problem posed also consists in obtaining a weapon whose swivel magazine cannot be replaced by another magazine. A problem also consists in providing a device making it possible to make the pivoting loaders irremovable.
• the solution to the problem posed consists in providing an individual firearm comprising a casing forming a magazine, mounted pivoting along a transverse axis XX (which is substantially horizontal when the weapon is in the position of use, and perpendicular to the longitudinal axis YY of the barrel of the weapon) on a shaft extending along said transverse axis XX and forming a pivot;
• the weapon comprises a breech casing comprising a magazine well of general shape substantially parallelepiped (or tubular of rectangular section whose angles are rounded) extending along a longitudinal axis ZZ (i.e.
