Abstract

FIELD: automatic small arms folded in traveling position. SUBSTANCE: in the firing position the barrel block and receiver block are interconnected by the hinge axle and pin. To bring the weapon to the traveling position, the pin is withdrawn from the ears and it becomes possible to turn the barrel block and receiver block about the hinge axle, the breechblock gets disengaged from the firing spring stops, the lug on the lower surface of the cocking handle stops against the restricting rib of the barrel block restricting the forward shift of movable parts. At the end of the turn the barrel and receiver blocks are locked by a spring-loaded catch. EFFECT: enhanced convenience in use. 5 dwg

Description

 The invention relates to the field of weapons technology and can be used in samples of small automatic weapons having a hard locking.

 The total length of small arms is important both for its combat use and for transportation, and especially for airborne landing. The length of small arms samples is determined by the sum of the dimensions of the following elements: muzzle, barrel, moving parts during reloading, butt. Reducing the total length of the weapon is possible by reducing the size of any of these elements, however, the practice of designing small arms has shown that a tangible gain in reducing the length of the weapon can be achieved by stocking or folding it in the stowed position, for example, the AKS-74 assault rifle, or by switching to the circuit Bullpap, excluding the butt from the design of weapons.

 Holding the butt in the folded position is a special spring-loaded latch on the side of the receiver. To bring the stock to the firing position, it is necessary to disengage the latch from the butt by pressing it. Then deploy the butt around the axis of the ears to the firing position, after which it is fixed using a spring-loaded hook.

 However, in this solution, the axial dimension in the transport position includes, in addition to the barrel with muzzle devices, the entire automation box. For weapons with a sufficiently long barrel (under a rifle cartridge), this solution does not meet the requirements of landing. In this case, it becomes necessary to separate the weapons at the junction of the barrel-box, with each of these elements meeting the requirements for landing on the axial dimension. Such samples are known in sports and hunting weapons. Dismantling for transportation and storage can be done by separating the barrel, as, for example, in a shotgun MC 21-12 V.V. Shinilov, P.M. Bendasov, N.A. Serebrennikov. Hunting and sports weapons, ed. v / o Riznoexport, 1972, p. 24 27, or by using a barrel that is rigidly connected to the breech (upper part of the receiver), as in a Benelli SL 121 shotgun. Grins Magazine, 1984 N 12, p. 32 33 and in firearms according to A.S. N 1338531, 1985. However, the separation of weapons into two parts creates operational problems: the possibility of accidental falls of assembled parts and their pollution in a combat situation; the possibility of incorrect installation of the barrel after separate storage, etc. which in practice is often recognized as unacceptable.

Known folding small arms containing a barrel unit, including hard locking elements, and a box unit with hinge eyes connected by the hinge axis [1]
To reduce the length in the transport position in the weapon, the barrel block and the box block are folded around the hinge with the horizontal direction of the axis of rotation, which serves to “break”. The barrel is locked by a combat ledge. This design of the weapon does not provide in the transport position an axial dimension equal to the length of the barrel. This weapon can only lead a single non-self-loading fire.

 The objective of the invention is the creation of a folding automatic weapon having hard locking elements, with an axial dimension in the landing (stowed) position equal to the length of the barrel unit: a barrel with a muzzle and combat stops of the bolt assembly.

 To solve the problem in a folding small arms containing a barrel unit and a box unit with hinge eyes, the barrel unit and the box unit are provided with finger eyes to ensure the installation of a vertically locking finger in a combat position, the hinge axis being located vertically and made on the barrel unit comb limiter of moving parts.

 The vertical location of the axis of rotation allows you to fold and put into combat position weapons with the store, which is an important factor for reducing the time of manufacturing the paratrooper to fire after landing.

 When folding the arms, the moving parts must be retracted until the bolt leaves the combat stops of the barrel unit. In this case, the forward movement of the moving parts in all intermediate and fully folded positions must be limited. This is achieved by the comb-limiter, made on the barrel unit.

 Fixing weapons in a fully folded position is carried out by the latch.

 In FIG. 1 shows a small arms in a combat position, right view; in FIG. 2 small arms in a fighting position, top view; in FIG. 3 section A of FIG. 2 on the fixing finger and eyelets; FIG. 4 a section In FIG. 2 on the hinge; in FIG. 5 weapons in the folded position, top view.

 Folding small arms contains a barrel unit 1 and a box unit automation 2 with moving parts 3.

 The barrel unit 1 has a barrel, a muzzle device, sights, forend, automation engine (if the gas outlet principle of automation is used), combat stops of the locking device.

 The automation box unit 2 has an automation box, a butt, a trigger, a magazine, a fire control handle, and moving parts 3.

 The cocking handle 4 of the moving parts 3 projects forward from the automation box unit 2.

 On the block of the barrel 1 and the block of the automation box 2 are made the eyes for the hinge "a", around the axis 5 of which folding occurs. Also, on the barrel block 1 and the automation box block 2, the finger eyes “c” and “c” are respectively made, into which a finger 6 is inserted, which is intended to be fixed in the combat position of the barrel block 1 relative to the box block 2.

 On the block of the barrel 1 also runs the ridge-limiter 7, which is designed to limit the forward displacement of the moving parts 3 during folding. On the lower surface of the cocking handle 4, a protrusion 8 is made, which interacts when folding with the comb-limiter 7. A spring-loaded latch 9 fixes the weapon in the folded position.

 In the combat position, the barrel unit 1 and the automation box unit 2 are interconnected by the axis 5 of the hinge "a" and the finger 6.

To bring the weapon into the landing (stowed) position, finger 6 is pushed out of the eyes "b" and "s". After this, the mutual rotation of the barrel unit 1 and the automation box unit 2 around the axis 5 of the hinge "a" becomes possible. By acting on the cocking handle 4, the bolt is disengaged from the fighting stops, and the protrusion 8 on the lower surface of the cocking handle 4 becomes opposite the ridge-limiter 7 of the barrel unit 1 and with the start of rotation around the axis 5 of the hinge "a" limits forward displacement of the moving parts 3. B at the end of the rotation (≈ 180 ^o ), the barrel unit 1 and the automation box unit 2 are locked in the folded position by a spring-loaded lock 9 located on the barrel unit 1. On the automation box unit 2 there is an eyelet with a hole into which the fixation fits torus 9. In this position, the weapon is packed in a case and is ready for landing or transportation.

 To bring the weapon into combat position, it is necessary to drown the spring-loaded latch 9 and turn the automation box unit 2 relative to the barrel unit 1 around the axis 5 of the hinge "a" until the holes of the eyelets of the finger "b" and "c" coincide, after which the finger 6 is inserted into them. If the holes of the fixing eyes (the eyes of the hinge and the eyes of the finger) coincide, the protrusion of the cocking handle 4 will not be blocked by the comb-limiter 7 of the barrel unit 1 and the moving parts 3 will go forward to their forward position under the action of the return spring.

 For firing a shot, it is necessary to reload with the handle on the handle and send the cartridge into the chamber, after which the weapon is ready to fire.

 Thus, this design of the weapon provides in the transport position an axial dimension equal to the length of the barrel unit.

 The enterprise produced prototype weapons and tested them with a positive result.
