Description

The invention relates to the automation of self-loading and automatic small arms such as a pistol, submachine gun, machine gun.

As an analogue, you can imagine the automatic pistol M1935HP {1, 146-159 pages}. Automation works on the principle of recoil of the barrel with its short stroke. On the breech of the barrel are placed on top of the semi-ring locking protrusions included in the semicircular grooves on the inner side of the shutter housing when swinging the breech of the barrel in a vertical plane using the bevels of the barrel and the ledge frame. Solid construction, when the shutter moves backward, the barrel moves simultaneously back and down until the locking tabs of the barrel exit the grooves of the shutter casing. At the same time, the line of aiming, throwing, and details of complex shape are changing. These are the disadvantages of this type of automation. Consequently, the high cost of weapons with reduced reliability

The closest in technical essence or prototype is the automation of pistols RG052, SR-1 (1, 454-457 pages), the automation of which works on the principle of recoil of the barrel during its short course. Locking, unlocking of the barrel channel is carried out by a barrel swaying in the vertical plane, which comes out of the shutter slots, ensuring the shutter barrel opens. The disadvantage of automation of the prototype is the complex shape of the barrel lock, therefore, the increased cost of weapons, sensitivity to pollution, reduced reliability, but high efficiency with a powerful cartridge, respectively.

The objective of the invention is, while maintaining such advantages of the prototype as the principle of automatic recoil of the barrel with its short stroke, linear rollback of the barrel with a powerful cartridge and high efficiency, to increase the reliability of automation, offering it from parts of a simple form while reducing their number. The specified technical result is achieved by the fact that the claimed automation of small arms consists of a locking protrusion in the breech of the barrel, placed in a window to remove the spent sleeve shell-shutter. The barrel and the shutter-casing move mutually along the horizontal and inclined guide, along the inclined guide and horizontal guide, or along the inclined guides, one and the other, respectively. Therefore, in the claimed automation there is no one part of complex shape, the barrel lock, as in the prototype. Consequently, the reliability of automation will increase, its cost will decrease.

Comparable analysis with the prototype allows us to conclude that the claimed automation of small arms is simpler in design and more reliable in comparison with the prototype. The author is not aware of such a design of automation with linear rollback of the barrel. Therefore, the claimed solution meets the criterion of "novelty."

Comparison of the proposed solutions with the prototype allowed us to identify signs that distinguish the claimed solution from the prototype, which allows us to conclude that the criterion of "Inventive step".

The essence of the technical solution is confirmed by the drawing (Fig. 1), which shows one design option of the inventive weapons automation, where the barrel 1 with a locking protrusion 3 in its breech, a shutter-casing 2 with a window for removing spent cartridges 6, a weapon frame 7 with emphasis the return spring 4, the rear stop of the barrel 9, the return spring 5, the inclined guide of the casing-shutter 8, the horizontal guide 10 of the barrel 1, the upper inclined surface 11 of the locking protrusion 3.

In the casing-shutter there is a rectangular window for removing spent cartridges 6 and where the locking protrusion 3 of the breech barrel 1 is placed when locking the bore. The upper surface of the locking protrusion of the barrel 3 is parallel to the inclined guide 8 of the casing-shutter 2. The locking and unlocking of the bore is carried out using the window to remove spent cartridges 6 and the locking protrusion 3. When rolling back, the casing-shutter 2 moves along the inclined guide 8 and the barrel along the horizontal guide 10 together until it stops 9. This is a short stroke of the barrel. At the moment when the barrel 1 reaches the stop 9, the locking protrusion 3 leaves the window for spent cartridges 6 and with further rollback only the casing-shutter 2 moves, the locking protrusion 3 with its upper inclined surface 11 slides along the inner surface of the casing-shutter 2, fixing the barrel 1 in the rollback position. When rolling, under the action of the return spring 5, the casing-shutter 2 moves separately from the barrel 1 until it reaches the breech of the barrel, at this moment the locking protrusion of the breech of the barrel 3 will be opposite the window to remove spent cartridges 6, then the barrel 1 and the shutter move together , while the locking protrusion of the breech of the barrel 3 enters the window for removing spent cartridges 6, the barrel and the casing shutter move together to the stop 4.

Using the additional front support on the weapon frame for the movable barrel, the claimed automation can be used in a submachine gun and machine gun. Therefore, the claimed automation is easily adaptable to many types of small arms lineup, consists actually of parts of a simple form, instead of the complex parts of the barrel lock of the prototype. Therefore, the claimed automation is slightly sensitive to dust and pollution, the reliability of automation will increase, its cost will decrease.

To understand the essence of the technical solution proposed by the author, I will give a detailed description of the design and operation of the claimed AUTOMATICS OF RUNNING ARMS WITH TILTED GUIDES. In FIG. 1 shows a design option of the inventive weapons automation, where the barrel 1 with a locking protrusion 3 in its breech, a casing-shutter 2 with a window for removing spent cartridges 6, a weapon frame 7 with an emphasis on a return spring 4, a rear emphasis on the barrel 9, a return spring 5, inclined guide of the casing-shutter 8, horizontal guide 10 of the barrel 1, the upper inclined surface 11 of the locking protrusion 3. In the casing-shutter there is a rectangular window for removing spent cartridges 6 and where the locking protrusion 3 of the breech barrel 1 is placed when locking anal trunk. The upper surface of the locking protrusion of the barrel 3 is parallel to the inclined guide 8 of the casing-shutter 2. The locking and unlocking of the bore is carried out using the window to remove spent cartridges 6 and the locking protrusion 3. When rolling back, the casing-shutter 2 moves along the inclined guide 8 and the barrel along the horizontal guide 10 together until it stops 9. This is a short stroke of the barrel. At the moment when the barrel 1 reaches the stop 9, the locking protrusion 3 leaves the window for spent cartridges 6 and with further rollback only the casing-shutter 2 moves, the locking protrusion 3 with its upper inclined surface 11 slides along the inner surface of the casing-shutter 2, fixing the barrel 1 in the rollback position. When rolling, under the action of the return spring 5, the casing-shutter 2 moves separately from the barrel 1 until it reaches the breech of the barrel, at this moment the locking protrusion of the breech of the barrel 3 will be opposite the window to remove spent cartridges 6, then the barrel 1 and the shutter move together , while the locking protrusion of the breech of the barrel 3 enters the window for removing spent cartridges 6, the barrel and the casing shutter move together to the stop 4.

A variant of the arrangement of weapons with the claimed automation and a return spring under the barrel, half-ring protrusions on the breech of the shutter and half-ring depressions on the inner surface of the shutter-casing, the outer and inner surfaces of the depressions and protrusions are parallel to the inclined guide, contains more details, but a simple, traditional form, therefore not less reliable. In FIG. 2 shows another variant of the weapon with the claimed automation, where the barrel 12 with a locking protrusion 16 in its breech, a casing-shutter 15 with a window for removing spent cartridges 13, a weapon frame 18 with an emphasis on the return spring 22 and a rear emphasis on the barrel 20, the return spring 19 , horizontal guide of the casing-shutter 17, an inclined guide along the casting line 21 of the barrel 12, the upper surface 14 of the locking protrusion 16. In the casing-shutter there is a rectangular window for removing spent cartridges 13 and where the locking protrusion 16 of the breech barrel is placed 12 when locking the bore. The upper surface of the locking protrusion of the barrel 16 is parallel to the horizontal guide 17 of the casing-shutter 15. The locking and unlocking of the bore is carried out using the window to remove spent cartridges 13 and the locking protrusion 16. When rolling back, the casing-shutter 15 moves along the horizontal guide 17 and the barrel along the throw line inclined guide 21 together to stop 21. This is a short stroke of the barrel. At the moment when the barrel 12 reaches the stop 21, the locking protrusion 16 leaves the window for spent cartridges 13 and only rollback casing 15 moves backward, the locking protrusion 16 with its upper horizontal surface 14 slides along the inner surface of the casing-shutter 15, fixing the barrel 12 in the rollback position. In FIG. 2 the mutual vertical movement of the barrel 12 and the casing-shutter 15 is due to the inclined guide along the cast line 21 of the barrel 12.

The next design option is AUTOMATIC ARMS OF TARGET WEAPONS WITH TILT GUIDES, where the barrel and the shutter guard are moved vertically both by the movement of the shutter guard along the inclined guide and the barrel along the inclined throw line together at the time of a short stroke. Therefore, in Fig.1 and Fig.2 such structures are already presented in parts, their operation is also described.

Using the additional front support on the weapon frame for the movable barrel, the claimed automation is applicable in a submachine gun and machine gun. Therefore, the claimed automation is easily adapted to many types of small arms layout, consists actually of parts of a simple form, instead of the complex parts of the barrel lock of the prototype. Therefore, the claimed automation is slightly sensitive to dust and pollution, the reliability of automation will increase, its cost will decrease.

The inventive AUTOMATION of a small arms with TILTED GUIDES, using an additional, front support on the frame of the weapon for the movable barrel, is applicable for a submachine gun and machine gun. Therefore, the claimed automation easily adapts to many types of small arms layouts, actually consists of parts of a simple form, instead of the complex shape of the part of the prototype, it does not impose special requirements on the accuracy of manufacturing parts. Therefore, the range of applications is expanding, the reliability of automation in dusty conditions will increase, its cost will be reduced in comparison with the prototype. What will make the use of the claimed AUTOMATICS OF RUNNING WEAPONS WITH TILT GUIDES in the production of weapons cost-effective.
