Description

The invention relates to military equipment and can be used in small arms with a device for selecting a right-handed or left-handed ejection sleeve.

Known firearms with a device for selecting a right-handed or left-handed ejection sleeve, adopted as a prototype (RU 2370719 C2, F41A 15/14, F41A 3/00, publ. 20.10.2009), containing a barrel, a receiver having on both sides windows for ejecting the sleeve, a shutter having a striker and two extractors, a slide carrier for the shutter holder, and an element controlling the ejection of the sleeve (switch for selecting the direction of ejection of the sleeve).

The disadvantages of the prototype are the complexity and large dimensions of the structure caused by the use of two longitudinally sliding extractors in the design of the gate assembly.

The proposed invention solves the problem: reducing the size and simplifying the design.

The technical result obtained by carrying out the invention consists in the possibility of using a device in small arms for selecting a left-side or right-side ejection of a sleeve with reduced dimensions and a simplified design.

The specified technical result is achieved by the fact that in a firearm with a device for selecting a right-handed or left-handed ejection of a sleeve containing a barrel, a bolt having two extractors, a receiver having windows for ejecting the sleeve on both sides, and a switch for selecting the direction of ejecting the sleeve, new is that both extractors are pivotally mounted on the axes in the shutter, and the switch is equipped with elements that can interact with the corresponding surfaces of the extractors and with the zy.

The claimed invention can be applied in automatic, semi-automatic or non-automatic weapons using any scheme of operation and type of locking.

Technical solutions with features distinguishing the claimed solution from the prototype are unknown and do not follow explicitly from the prior art. This suggests that the claimed solution is new and has an inventive step.

To illustrate the invention, the following is an example of the operation of the device for selecting a right-handed or left-handed ejection of a sleeve, used in automation based on the use of energy of powder gases discharged from the bore to the gas engine with the driving link of the automation - shutter frame and locking of the bore by lateral movement shutter. This example does not limit or limit the scope of legal protection of the invention.

The invention is illustrated by drawings, where Fig. 1 shows a longitudinal section of a firearm with the bolt locked; figure 2 is a longitudinal section of a firearm at the time of ejection of the sleeve; figure 3 is a section aa of figure 2.

A firearm with a device for selecting a right-handed or left-handed ejection of a sleeve comprises a barrel 1, a receiver 2, a breech 3, a shutter 4, symmetrically located extractors 5, pivotally mounted on the axles 6 in the shutter 4 with the possibility of rotation and spring-loaded springs 7, a movable switch 8 for selection of the direction of ejection of the sleeve. On the switch 8 there are protrusions 9 for interacting with the protrusion 10 of the extractors 5 for turning the latter and protrusions 11 for interacting with the bottom 12 of the sleeve 13. On the receiver 2 there are windows 14 for ejecting the sleeve 13.

The device operates as follows.

To select the direction of ejection of the sleeve switch 8 is installed in one of its extreme (right or left) positions (in the example shown in Figs. 1, 2, 3 - in the extreme left position). After firing a shot, the shutter 4 unlocks the barrel 1 and begins to move backward, holding the sleeve 13 in its extractors 5. With a further backward movement, the shutter 4 meets switch 8 in its path, and the protrusion 9 of the switch 8 acts on the protrusion 10 of one of the extractors 5, forcing the extractor 5 turn and release the bottom 12 of the sleeve 13 on one side, depending on the extreme position of the switch 8. Next, the bottom 12 of the sleeve 13 interacts with the protrusion 11 of the switch 8, as a result of which the sleeve 13 receives an impulse and, turning around 5 g of the other extractor is emitted through the window 14 to release liner 13. Thus occurs the ejection of the sleeve 13 to the left relative to the weapon. To select the right-hand direction of ejection of the sleeve 13, it is enough to move the switch 8 to another extreme position.

Claims (1)

A firearm with a device for selecting right-side or left-side ejection of a sleeve, comprising a barrel, a shutter having two extractors, a receiver having windows for ejecting the sleeve on both sides, and a switch for selecting a direction for ejecting the sleeve, characterized in that both extractors are pivotally mounted axes in the shutter, and the switch is equipped with elements with the possibility of interaction with the corresponding surfaces of the extractors and with the bottom of the sleeve.
