The invention relates to handguns and is the firearm has the shorter length compared to systems in which the magazine is located in front of the trigger guard. Besides, the proposed firearm has the ability to quickly disassemble into the main components, which significantly reduces the dimensions of the firearm in the transport position. In addition, the magazine is also protected from loss when moving with the assembled firearm. These results are achieved by the fact that the magazine of the firearm is located above the trigger guard, while access to the magazine is carried out only when the firearm is opened by turning the upper part of the receiver relative to its lower part. At the same time, the upper part of the receiver can be easily detached from its lower part to reduce the dimensions of the firearm during transportation.

TECHNICAL FIELD

The invention relates to the field of guns technology and can be used in firearms with the fed of the cartridges from the magazine, mainly hunting and sporting.

BACKGROUND OF THE INVENTION

Known designs of firearms, where to reduce the length of the firearm the magazine is located above the trigger guard, for example U.S. Pat. No. 3,509,654A, DE19538425A1, U.S. Pat. No. 7,963,062B1. However, these systems have the complex design and do not provide the convenient loading.

Also known is the firearm U.S. Pat. No. 1,077,103A, which can be quickly disassembled into two main parts, which facilitates transportation. The disadvantage of this design is that the magazine is located in front of the trigger guard, which does not allow to reduce the length of the firearm in the assembled position.

DISCLOSURE OF THE INVENTION

The present invention solves the following tasks:reduction the length of the firearm in the working position;ensuring the convenience of disassembling the firearm for transportation and assembly back;ensuring the protection of the magazine from the loss when moving with the firearm is brought into working position;providing acceptable convenience when changing the magazine.

To achieve these results, the magazine in the proposed firearms is located above the trigger guard, while access to the magazine is provided after turning the upper part of the receiver relative to its lower part, and the upper part of the receiver itself has the ability to separate from the lower part of the receiver.

THE BEST EMBODIMENT OF THE INVENTION

The firearm (FIG. 1), containing the barrel1, the upper part of the receiver3.1, the lower part of the receiver3.2, the buttstock6, the hinge3.10(FIG. 1,FIG. 2,FIG. 3,FIG. 4), allowing the upper part3.1rotate relative to the lower3.2.

The upper part of the receiver3.1(FIG. 2,FIG. 3,FIG. 4,FIG. 5) contains the cutout3.11, the lower part3.2contains the cutout3.21. When parts3.1and3.2are combined, cutouts3.11and3.21form the space (FIG. 4, view A;FIG. 5, view A), in which magazine4is placed (FIG. 4, view B) with cartridges7, while magazine4located above the trigger guard3.22.

Access to the magazine4(FIG. 1,FIG. 2) is carried out after turning the upper part of the receiver3.1on the hinge3.10relative to the lower part of the receiver3.2.

The variant of the proposed firearm (FIG. 5), when the magazine4(FIG. 5, view B) is located eccentrically relative to the vertical longitudinal plane Y passing through the longitudinal axis1.1of the barrel1.

The variant (FIG. 6, view A), when the trigger mechanism with the trigger3.4is rigidly fixed on the top of the receiver3.1and turns together with it on the hinge3.10. To protect the trigger mechanism with the trigger3.4, used the guard3.41.

The variant (FIG. 6, view B), when the trigger mechanism with the trigger3.5is rigidly fixed on the lower part of the receiver3.2and remains on it when the upper part of the receiver3.1is rotating.

The variant (FIG. 7, view A), when turning the upper part of the receiver3.1on the hinge3.10, the magazine4remains in the lower part3.2.

The variant (FIG. 7, view B), when turning the upper part of the receiver3.1on the hinge3.10, the magazine5remains on the upper part3.1.

The scheme (FIG. 8) of the process of disassembling the firearm for transfer to the transport position, where:

view 2—the position when the firearm is open;

view 3—separation of the upper part and the magazine from the lower part;

view 4—position for transportation and storage.
