Abstract

FIELD: small arms for fire from the shoulder. SUBSTANCE: hunting carbine comprises a firing mechanism consisting of a hammer with a firing spring, sear and trigger. The firing mechanism is mounted in the trigger housing installed and fixed on the receiving bottom. The safety lock is furnished with a safety lug pressing the receiver to the receiver bottom at turning. Through longitudinal slots are made in the receive bottom. The firing spring ends are bent and push against the receiver bottom through the longitudinal slots. EFFECT: improved design. 2 dwg

Description

 The invention relates to the field of self-loading firearms, in particular hunting.

 There are many known models of hunting weapons made on the basis of the Kalashnikov assault rifle (AK). The main requirement when creating civilian weapons is to use them only in single-shot mode and, in this regard, to ensure the impossibility of artisanal conversion of weapons into automatic ones.

 Known hunting self-loading carbine "Saiga", designed on the basis of AK [1] containing the receiver, which houses the trigger. To exclude automatic shooting, a number of changes were introduced into the weapon: the self-timer and protrusion on the bolt frame were removed, the whisper of a single fire was shortened, the trigger and safety clip were moved back, the design of the store was changed.

 The circuit diagram of the AK assault rifle is saved. However, artisanal improvements and the introduction of missing parts are enough to turn a hunting rifle into a combat machine.

 In numerous foreign hunting carbines made on the basis of the AK assault rifle, the trigger mechanism is mounted directly in a stamped receiver, and the circuit diagram of the trigger mechanism is similar to that of the AK assault rifle, in connection with which all these structures can easily be modified in a makeshift way and turned into military automatic weapons .

 Known hunting carbine "Bear" (2), in which the trigger mechanism, including a trigger with a mainspring, a whisper and a trigger, is mounted in a separate trigger box, which is installed below in the receiver, made in the form of a frame.

 The disadvantage of this design is the complexity and complexity of manufacturing, the large metal receiver, milled. In addition, such a scheme cannot be used in the stamped design of the receiver used in the Kalashnikov assault rifle, due to its low rigidity.

 The objective of the proposed technical solution is to create a reliable technological design of self-loading weapons with the maximum unification of components and parts with an AK automatic, as well as ensuring the impossibility of converting hunting weapons into combat automatic.

 To solve this problem, in a hunting carbine containing a receiver, in which a trigger box with a trigger mechanism, including a rotary trigger with a combat spring, and a fuse, a trigger box are installed at the bottom of the receiver, a fuse is provided with a protrusion that interacts with the upper part of the trigger boxes, the bottom of the trigger box is made with through longitudinal grooves, and the ends of the mainspring are bent and placed in through longitudinal grooves with the possibility of interaction with the bottom of the receiver boxes.

The invention is illustrated by drawings, which depict:
in FIG. 1 hunting carbine, a cut along the receiver;
in FIG. 2 trigger box housing, top view.

 Structurally, the hunting carbine is made as follows. In the receiver 1 has a trigger box 2 trigger mechanism. The trigger mechanism includes a rotary trigger 3, a spring loaded torsion spring 4. The ends 5 of the mainspring are bent. Trigger 3 is held in the firing position by a spring-loaded sear 6, which is connected through the rod 7 to the trigger 8. The trigger 2 is fixed to the bottom of the receiver 1 using the front groove 9, with which it abuts against the protrusion 10, and the hole 11 with which it sits on protrusion 12. In the upper part, the box 2 is based on the bevel 13, with which it abuts against the jumper 14. On top, the trigger box 2 is pressed to the bottom of the receiver 1 by the protrusion 15 of the rotary fuse 16. The fuse 16 has two fixed positions: e "and" fire ", while the box 2 in both positions of the fuse remains pressed to the bottom of the receiver 1. In the bottom of the housing of the trigger box 2 there are two through longitudinal grooves 17, through which the bent ends 5 of the mainspring pass and abut against the bottom of the receiver 4. In the assembled position, the ends of the spring are constantly in tension and push the trigger box up, whereby all gaps are selected, the trigger box has no play and always occupies the same position.

 To disassemble the receiver, the fuse 16 is removed from a fixed position, rotated and removed from the holes of the receiver, releasing the trigger box, which is freely removed from the receiver. In this position, it is convenient to clean and lubricate the weapon.

 To assemble the receiver, the trigger box with the front groove 9 is inserted into the protrusion 10 until the bevel 13 rests in the jumper 14 and put with the hole 11 on the protrusion 12. Then, the fuse 16 is inserted into the holes of the receiver 1 and turned to one of the fixed positions “protection” or “fire” ", while the protrusion 15, overcoming the resistance of the ends 5 of the spring 4, presses the box 2 to the bottom of the receiver.
