Description

[Detailed description of the invention] Relating to devices for automatic firearms.

(Prior Art) Automatic weapons with a wedge-shaped closure require a special device for ejecting the empty cartridge from the gun barrel, since the wedge-shaped closure releases the empty cartridge from the gun barrel. This is because it is not in a condition to be extracted from the body. This ejection device for empty cartridge reservoirs in the gun barrel has two swiveling ejection levers that fit into the ejection grooves of the empty cartridges and, by a short swiveling movement, remove residual gas. Accelerating the cartridge with pressure, the ejected empty cartridge has a relatively large kinetic energy, and without the receiver the receiver would be blown very far and be dangerous, or the receiver would destroy the hole. .

(Problem to be solved by the invention) The problem to be solved by the invention is to create a device in which the kinetic energy of an empty cartridge is nullified again before it falls into the cartridge hole. . At the same time, the receiver according to the invention prevents cartridges ejected by the device or "unfired" from reaching the cartridge bore.

(Problem and means for solving the problem) The problem of the present invention is to provide a swing lever, an impact damper, and a cartridge/yaft as described in claim 1, wherein an empty cartridge is placed on the swing lever. A spring is provided which abuts the pivot lever and is biased to pivot the pivot lever to its starting position, the shock damper being pivotally mounted to the pivot lever and causing the empty cartridge to pivot. By being energized to dampen the movement of the pivot lever when it comes onto the lever, and allowing the empty cartridge to fall through the cartridge shaft into the shot hole after impacting on the pivot lever. resolved.

Preferably, the cartridge hole is provided with a pivotable flap that is partially locked to receive an "unfired" cartridge that must not fall into the cartridge hole. be done.

Embodiments An embodiment of the receiving device for empty cartridges according to the invention will be explained in detail with reference to the drawings.

According to FIG. 1, the empty cartridge 10 is removed from the gun barrel 130 by the residual gas pressure and by the two ejection levers 11.
After being deflected by the guide plate 15, the empty cartridge ejected from the cartridge impinges on the pivoting lever 1.4. The barrel 13 is movable by means of a wedge closure 16, which is in its lowest position and movable in the direction of the double arrow A. When moving to the position shown, the wedge-shaped closure 16 abuts a pawl 17 which is pivotable about the shaft 18 at the lower end of the dosing lever 11, so that the dosing lever 11 is moved to the position shown. At this time, the empty cartridge 10 is ejected by the two withdrawal levers 11.However, the firearm shown in FIG.

According to FIGS. 1 and 2, the mentioned swivel lever 14 is mounted pivotably at its upper end around an axle 19 and at its lower end is pivoted via an axle 20 to a piston rod 21 of a shock damper 22. supported. The impact damper 22 is rotatably supported on the cartridge shaft 24 via a shaft 23. The hydraulic shock damper 22 is a commercially available part and therefore will not be described in detail. A bolt 25 is supported on the pivot lever 14, within which is a spring 26 which urges the pivot pin 14 to pivot to the position shown. The bolt 25 is movable into a sleeve 27 fixed to the cartridge shaft 24, in which the rear end of a spring 26 is supported on a closure device 28.

3 and 4, six flaps 29 are mounted on the lower edge of the cartridge shaft 24 so as to be pivotable about two axes of 3°. Two springs 32 are supported on each spring lid 29 via bolts 31, and the springs connect the spring lid 29 to the fourth
Force it to hold it in the position shown in the figure. The rod 34 is moved in the axial direction by the hydraulic RJ device 33.

This rod 34 serves to lock three of the six flaps 29 at the same time, as can be seen in FIGS. 4 and 5. The three flap lids 29, which are lockable for this purpose, each have a stop 35, which rests on a rod 34, whereby the flap lids 29 are locked.

According to FIG. 5, the rod 34 has a recess. Due to the movement of the rod 34 in the axial direction, the concave portion 36 becomes the stopper 35.
As soon as the splash lid 29 is reached in the range , the splash lid 29 can be pivoted freely.

(Function) According to FIG. 1, the cartridge 10 is extracted from the cartridge chamber 12 of the firearm 11 and thrown rearward by the two throwing levers 11 that are fitted into the extraction grooves 38 of the empty cartridge 10 of the cam 37. Served. The ejected ammunition cylinder 10 first hits the guide plate 15 and slides on the guide 39. Next, empty cartridge 1
The bottom of the zero bump hits the turning lever 14. Swivel lever 14
By pressing the cartridge 10 upward, the swing lever is activated by the spring 26.
, and this pivoting movement is damped by the shock damper 22 . When the cartridge 10 hits this pivot lever 14, most of the kinetic energy of the empty cartridge 10 is converted into heat by the impact damper 22. After the impact of the empty cartridge on the pivoting lever 14, the empty cartridge falls onto the pawls 29 which are swiveled against the force of the spring 32, so that the empty cartridge 10 is freed from the six pawls 29. It can fall through the gap into the cartridge hole 40.

If unfired ammunition is ejected when the firearm is reseated, that is, when the gun barrel 13 is reseated against the force of a recoil spring (not shown), the cartridge is prevented from falling into the ammunition discharge hole 40. must be done. The locking of the three flaps 29 is also effected automatically upon firing of the firearm, so that the ejected cartridge cannot fall into the ammunition hole 40. In order to lock the three flap lids 29, the rod 34 is moved by the hydraulic drive 33 so that the recess 36 is no longer in the area of the stop 35 of the flap lid 29 and this stop 35 of the flap lid 29 is placed on the rod 34. It can be moved to be supported. The splash lid 29 connects its stopper 35 to the rod 3
As soon as it is supported on 4, the flap 29 can no longer be pivoted.
