DESCRIPTION

Muzzle booster an externally driven automatic weapon, especially

machine gun

The invention is concerned with a muzzle booster of an externally powered weapon, in particular a machine gun and a machine gun.

With machine guns or machine guns distinguish between internally and externally driven weapons. For self-propelled guns, the gas pressure for unlocking a shutter is used and the charging process initiated. In externally driven arms, the locking and unlocking of the closure means takes place, etc., using an electrical actuator.

An automatic rifle-gas operated disclosed in DE 20 2008 000 357 U1, a gas operated DE 00C0000020MAZ. To support the functioning of 1,839,167 U is proposed to provide a return amplifier in a weapon used for shooting blank cartridges in DE. A muzzle brake with fire damper for automatic weapons, and in which the opening of the shutter is actuated by the pushed-on gas pressure barrel guns, also described in DE 1953539 A1. A blowback discloses the AT 257 422 B, while the DE 10 2009 056 253 B3 published a Rückprailsperre for a locking slide of a closure of a Gasdruckiaders.

Externally driven weapons are known from DE 10 2009 056 735 A1, DE 10 2008 015 892 B3, DE 10 2007 048 468 A1 and DE 10 2008 060 217 A1. In such weapons weapons return can be used to animals to be detected as such a shot, as disclosed in DE 10 2008 060 216 A1. From the successful shot a carriage is moved from one position to another while remaining with of lack of income in the first position. Thus, the carriage can not be unlocked not taken with- by a cam of the drive and functionally connected to the carriage lock. A muzzle brake on the barrel for a externally driven weapons serves to minimize the weapons return.

Here the invention, the object is to provide a means by which not only an emergency stop but other follow-up functions for safety and / or function of an externally driven weapon can be fired.

This object is achieved by the features of claim 1. Advantageous embodiments are contained in the subclaims.

The invention is based on the idea to generate a sufficiently good and reproducible signal for reliable detection of a function externally driven automatic weapon, especially with a weapon with a small weapons return.

the idea by integrating a recoil amplifier instead of a device normally used for the reduction of a recoil, such as a muzzle brake is released. The shape of the recoil amplifier is funnel-shaped. The simple funnel shape, a higher recoil of the gun barrel is produced. This reinforced tube return generates a safe signal, for example for shot detection and derived functions of a spark-driven automatic weapon (including machine guns). Follow functions available. For example, a fault detection, a rapid stop and a trigger, for example, temperature dependent to necessary weapon barrel change. For example, if a predeterminable excess load determined, for example, via a shot counter (EP 2518430 A2), a change of the gun barrel can be accomplished. In a multi-barrel weapon with a tube bundle consisting of a plurality of weapon barrels, a new weapon barrel may be placed in front of the shutter (rotated).

the increased recoil can be compensated by an internal return loss, which causes a slight force acting on a carrier system of the weapon, but without reducing the arms return itself. This may be preferred two maintenance-free return damper in the focus of the returning crowds. Such a return damper may be formed by a spiral in the casing. The maintenance results from the closed, modular design. The two return damper are in turn inserted in a recess of the weapon cradle and easily locked. The opposite the weapon housing (part of the recoiling mass) ensures stationary cradle that no increased shot load is applied to other components, such as motors, sensors, target devices and / or auxiliary units, and a relative to the weapon housing stationary inlet guide, that no vibrations on the ammunition be exercised.

Reference to an embodiment with drawing The invention will be explained in more detail. It shows:

Fig. 1 is a perspective sectional view of a recoil amplifier,

Fig. 2 is a perspective view of the recoil amplifier in an application

Fig. 3 the recoil amplifier of FIG. 2 with a shaft mounted in the weapon return loss.

Fig. 1 shows in a perspective sectional representation a gun barrel 1 a here in Fig. Partially shown externally driven weapon 10 3, such as automatic weapon or machine gun, with a muzzle booster 2, in which the front end 3 of the barrel 1 is preferably smoothly transitions. The recoil amplifier 2 may be carried out with the gun barrel 1 in one piece. The recoil amplifier 2 preferably has a simple funnel shape. 4 Alternatively, the funnel-shaped recoil can be a muzzle brake screwed onto the front end of the weapon tube or fastened in another way amplifier 2 also similar.

In FIG. 2, a plurality of weapon barrels are 1 (tube bundle 9) represented, each with a muzzle booster 2. The effect of the recoil amplifying is only given by the system (barrel 1, recoil amplifier 2), which is located in the firing position of the machine gun 10, preferably by the system, which is located in the lower position / posture. 5

The weapon 10 has its part to a weapon housing 22 which is lafettierbar in a weapon cradle 23 and enables an internal return of the recoiling mass of the weapon cradle 6 within 23rd

The operation of the recoil gain at the externally driven weapon 10 is as follows:

With firing is in a known manner an antibody directed against the weft direction pulse to the recoiling mass of the weapon 6, as the gun barrel 1, the weapon housing 22, etc., exerted. This pulse is now supported by the shape of the recoil amplifier 2, here by the funnel shape 4, at the front end 3 of the barrel 1, that is, increased. The recoiling mass 6 thus experience a greater return. This return of the weapon housing 22 generated by the gain a sufficiently strong and reliable signal that allows a review of the function and thus the reliability of the machine gun 10th This preferably mechanically by the recoiling mass 6 and the return of the weapon housing 22 triggered signal is then for example used to count the number of shots. If necessary, an emergency stop function can be activated. Furthermore, can build another function triggers an externally driven automatic weapon 10 to this signal. In this case, the mechanical signal into an electrical signal can also be, for example, by a switch etc. for the shot count, that is, are converted according to the further use of the signal.

The muzzle booster 2 is used in this externally driven weapon as a functional part, ie as an amplifier part for a functional check of the weapon 10 itself, not as an active part, as in known Rückstoßiadern.

shown in Fig. 3 is an internal return loss 20, here for example, with two return dampers 21, 6, the center of gravity of the recoiling mass, the return loss 20 used here comprises two return damper 21, consisting of a housing for receiving a spring (eg coil spring not shown in detail ) and applied to both sides at the end faces of the housing 33 bolt 31, 32 as end points or contact pins. These two pins, the front pin 31 and the rear stud 32 are, in turn, placed preferably between steady rest 30 of a holder of the weapon tube / the weapon tubes 1, V, 1 "(= the tube bundle 9). The return damper 21 are in recesses 34 of the weapon cradle 23 inserted and firmly integrated therein. They have the weapon housing 22 (the lunettes 30) a game 25. weapon cradle 23 and a feeder 24 are stationary in relation to the rückiaufenden measuring 6.

With weft and return the gun barrel 1 are moved (with the tube bundle 9) and the weapon housing 22 with retention of the / of the weapon tubes 1, 1 ', 1 "opposite to the weft direction to the rear. This is made possible a sufficient path of the weapon housing 22 is realized. Steamed are the weapon housing 22 and the recoiling mass 6 by the fixed embedded in the cradle 23 return damper 21, to which the resonating with the recoiling mass 6 lunettes 30 abut during recoil. that is, as seen in the weft direction abuts against the front ends of the return damper 21 when the weapon housing 22 has reached the adequate way to the front bezel 30 on. the game 25 is used up there and moved backwards (against the weft direction). When reinforced by the recoil amplifier 2 return, the front bezel 30 hits as already described, on the front pin 31 of the return damper 21. This, in addition to Dämpfun g generate the signal that can be used for functional testing of the weapon 10th Swinging the rückiaufenden masses 6 and thus the weapon housing 22 back in the weft direction, strikes the rear bezel 30 to the rear bolt 32nd
