Description

The invention relates to automatic and semi-automatic firearms and is applicable to weapons of any systems of small caliber.

Ammunition systems are known, consisting of a magazine with a spring-loaded feeder and a magazine slot for weapons / cm. for example, "Manual on a small business" M .: Military Publishing 1970 p.4-19 /. The disadvantage of this system is that after the ammunition is used up, the magazine must be removed. In addition, a store with a carob shape is inconvenient to insert and remove, as movement in an arc is less orthopedic for the loader’s hand - simple direct movement is more confident and faster, therefore reloading the carob store takes 1 second more time than direct. And the experience of military operations in Afghanistan has revealed the urgent need to reduce the reload time of weapons, especially machine guns. In addition, when firing a machine gun, if the trigger is released immediately after the last cartridge has been used up or when shooting single, the end of the cartridges goes unnoticed, which can lead to the death of a soldier.

The technical result is the simplification of charging and self-disconnection of the store when the ammunition is used up, which is an alarm about the end of cartridges.

To do this, the magazine retention latch is mechanically connected with the feeder in the upper or upper / in the presence of one cartridge / its position, or with an element mechanically connected with the feeder or with cartridges, and if the magazine has an indirect, for example, cone shape, then its working the end has straight guides. The mechanical connection can be located both in the weapon and in the store, and in the latter case, for some design solutions, the counter catch located in the weapon can serve as the stop for the latch located in the store. In systems where the opening of the latch is not designed to lower the magazine, but on the last cartridge, there is a magazine release lock in the form of an additional latch, mechanically connected to the protrusion located on the path of movement of the shutter or related elements.

The design, designed for the last cartridge, differs from the first in that in the first design, the store is separated after the last shot, when the bolt has stepped back and the feeder is released. At the same time, the weapon remains unworkable for some time.

And in the design, designed for the last cartridge, the store is separated before the last shot in the phase of sending the cartridge. In this case, weapons, at least when shooting solitary, all the time remains charged.

For a more energetic separation of the magazine from the weapon there is a pushing spring attached to the magazine or weapon. And so that during training firing the store does not fall on a hard surface or in the dirt, there are loops on the store and weapons, to which carbines of the safety cord are connected.

Mechanical communication can be carried out either directly or through traction, a two-armed or a single-armed spring-loaded or spring-loaded lever, etc.

Figure 1 shows a structural diagram of an ammunition system. Figure 2 - four specific examples of the location of the linear guides on the carob store. Figure 3-6 - specific design solutions.

Structurally, the system consists of element 1, which perceives the end of the ammunition or the moment when there is one cartridge or unitary shot left in the store, it can be a feeder, an element associated with it, for example, a slide delay in the PM pistol, or directly cartridges. A mechanical connection 2 is in interaction with this element, and with it a latch 3 for holding the housing 4 of the magazine.

In designs designed for the last cartridge, to prevent premature detachment of the magazine, there is a latch 5 of the lock connected to the protrusion 6 in the path of the shutter or element 7 connected to it. To accelerate the separation of the magazine there is an ejection spring 8.

This system works as follows: after using up cartridges, element 1, through mechanical connection 2, opens the latch 3 and the empty magazine 4 is separated from the weapon by the action of its own weight and spring 8. In designs designed for the last cartridge, after the release of the latch 3, the magazine is held by the latch 5 of the lock until the last cartridge is removed from it by the shutter 7, which / or the associated element / presses on the protrusion 6 when rolling, opening the latch 5 blocker. The store is detached.

Figure 2 shows the main options for the location of the guides 9 on the housing 4 of the carob store. Intermediate are also possible.

Depending on the type of magazine / direct, carob, disk, drum / and the type of mechanical transmission / direct, traction, pusher, one- or two-arm lever, shaft, etc. /, and the location of the mechanical connection, and latches, various examples are possible specific implementation.

The systems in FIGS. 3-5 are comprised of a magazine case 4 with a feeder 10 spring-loaded with a spring 11. For holding the magazine there is a latch 3, and for manual disconnection, a flag 12. Moreover, in FIGS. 3 and 5, the latches are formed by a bend of an elastic plate, on which and are attached.

Figure 3 also has a rod 13, attached, for example by resistance welding, to the feeder 10 and the flag 12.

Figure 4 shows the staggered cartridges 14, between the tips of which is the protrusion 15 of the two shoulders of the lever 16, spring-loaded spring 17 and mounted on the axis 18 inside the guide 19.

5, the latch 3 is located on an elastic plate 20 attached to or which is part of the rear wall of the magazine, and the latch 3 is supported by an additional latch 21 in the form of an angled elastic plate, one end attached to the weapon body. On the housing 4 of the store there is a protrusion 22 for the latch 5 of the lock 23 mounted on the axis 24 and having a protrusion 6 located on the way of rolling the handle 25 of the shutter frame.

Figure 6 shows the magazine 4 in the nest of weapons 26. In the wall of the nest there is a groove 27, in which there is a glass 28 with a tooth 29. A tensile ejector spring 8 is attached to the glass and the bottom of the groove.

The systems in FIGS. 3 and 4 work as follows: as the cartridges are used up, the feeder 10, under the action of the spring 11, is shifted to the open end of the magazine 4 and after the last cartridge has been used up via mechanical coupling in the form of a rod 13/3 / or protrusion 15 on the lever 16 / Fig. 4/ opens the latch 3 and the magazine falls out of the weapon under the influence of its own weight.

The system of FIG. 5 works similarly except that the latch 3, under the action of the elastic plate 20, enters the groove of the feeder 10 at a time when there is still one cartridge left in the magazine. This happens after the rollback, and so that the store does not prematurely separate with the last cartridge, it is held by the protrusion 22 by the latch 5 of the lock 23.

During rolling, the cartridge is sent to the barrel and the bolt or, in relation to the AKM submachine gun, with the handle 25, presses on the protrusion 6 of the lock and the empty magazine is separated. At the same time, if firing was carried out with single shots or at that moment the trigger was released, the weapon remains re-operational during reloading: at any moment it is ready to fire one shot. To reload, it remains only to insert a new store and without jerking the shutter, you can continue shooting. It should be added that in this case, the use of a slide delay in a machine is similar to a PM pistol.

For faster and more reliable separation of the magazine in the above systems, there may be an ejection spring 8 / Fig. 6/, which, when the magazine is attached, stretches, and after disconnecting the magazine is compressed and the tooth 29 of the glass 28 pushes an empty magazine 4.

The use of the invention will significantly increase the combat effectiveness of motorized rifle and landing troops, especially in fleeting oncoming, close, urban battles.
