Recoil intensifier of an externally powered machine weapon, in particular a machine gun

Abstract

For an externally powered weapon, in particular a machine weapon and a machine gun, having at least one barrel, a recoil intensifier at the front end of the barrel is proposed to intensify a weapon return of the returning masses of the weapon and to generate and intensify a signal for monitoring, in particular functionally monitoring, the weapon. The recoil intensifier is of a flared form. The signal intensified by the intensification is used for example for counting the number of shots fired, initiating an emergency stop function, etc. Depending on the further use, the mechanically intensified signal may be converted into an electrical signal.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus, are not limitive of the present invention, and wherein:

(2) FIG. 1 shows a perspective sectional representation of a recoil intensifier;

(3) FIG. 2 shows a perspective representation of the recoil intensifier in one application; and

(4) FIG. 3 shows the recoil intensifier as shown in FIG. 2 with a return damping device mounted in the weapon.

DETAILED DESCRIPTION

(5) FIG. 1 shows in a perspective sectional representation the weapon barrel 1 of an externally powered weapon 10 partially represented in FIG. 3, such as a machine weapon or machine gun, with a recoil intensifier 2, into which the front end 3 of the weapon barrel 1 goes over, preferably without a transition. The recoil intensifier 2 may be formed in one part with the weapon barrel 1. The recoil intensifier 2 preferably has a simple funnel shape 4. Alternatively, the funnel-shaped recoil intensifier 2 may also be screwed onto the front end of the weapon barrel or be fastened in some other way in a manner similar to a muzzle brake.

(6) In FIG. 2 a number of weapon barrels 1 are represented (barrel cluster 9), each with a recoil intensifier 2. The effect of intensifying the recoil is only provided by the system (weapon barrel 1, recoil intensifier 2) in the firing position of the machine gun 10, preferably by the system in the lower position 5.

(7) The weapon 10 has for its part a weapon housing 22, which can be carrier-mounted in a weapon cradle 23 and allows an internal return of the returning masses 6 within the weapon cradle 23.

(8) The way in which the recoil intensification functions in the case of the externally powered weapon 10 is as follows:

(9) When a shot is fired, a momentum counter to the firing direction is exerted in a known way on the returning masses 6 of the weapon, such as the weapon barrel 1, the weapon housing 22, etc. This momentum is boosted, i.e. intensified, by the shape of the recoil intensifier 2, here by the funnel shape 4, at the front end 3 of the weapon barrel 1. The returning masses 6 thereby undergo an intensified return. By being intensified, this return of the weapon housing 22 generates a sufficiently strong and dependable signal to allow the function, and consequently the functional dependability, of the machine weapon 10 to be checked. This signal, which is preferably triggered mechanically by the returning masses 6 or the return of the weapon housing 22, is then used for example to count the number of shots. If necessary, an emergency stop function may also be activated. Furthermore, the initiation of further functions of an externally powered machine weapon 10 may also be based on this signal. In this case, the mechanical signal may also be converted into an electrical signal, for example by a switch for shot counting, etc., i.e. in a way corresponding to the further use of the signal.

(10) In the case of this externally powered weapon, the recoil intensifier 2 serves as a functional part, i.e. as an intensifier part, for functional checking of the weapon 10 itself, not as an active part, as in the case of known recoil-operated automatic guns.

(11) Represented in FIG. 3 is an internal return damping device 20, here for example with two return dampers 21, at the center of gravity of the returning masses 6. The return damping device 20 used here comprises two return dampers 21, formed of a housing for receiving a spring, for example a spiral spring (not represented any more specifically) and bolts 31, 32 attached on both sides to the end faces of the housing 33 as end points or contact bolts. These two bolts, the front bolt 31 and the rear bolt 32, are for their part preferably placed between steady rests 30 of a securing device of the weapon barrel/weapon barrels 1, 1′, 1″ (≙barrel cluster 9). The return dampers 21 are placed in clearances 34 in the weapon cradle 23 and fixedly integrated therein. They have a backlash 25 with respect to the weapon housing 22 (the steady rests 30). The weapon cradle 23 and also a feeder 24 are fixed in place with respect to the returning masses 6.

(12) With firing and return, the weapon barrel 1 (with barrel cluster 9) and the weapon housing 22 with the securing device of the weapon barrel or barrels 1, 1′, 1″ are moved rearward, counter to the direction of firing. In this case, a sufficient displacement path of the weapon housing 22 is made possible or realized. The weapon housing 22 and the returning masses 6 are damped by the return dampers 21, which are fixedly incorporated in the cradle 23 and are struck by the steady rests 30 oscillating with the returning masses 6 during the recoil. In other words, seen in the direction of firing, the front steady rest 30 strikes the front ends of the return dampers 21 when the weapon housing 22 has traveled over a sufficient displacement path. The backlash 25 is in this case used up and displaced to the rear (counter to the direction of firing). As already described, with the return intensified by the recoil intensifier 2, the front steady rest 30 hits the front bolt 31 of the return damper 21. In addition to the damping, this can generate the signal that can be used for the functional testing of the weapon 10. When the returning masses 6, and consequently also the weapon housing 22, oscillate back in the direction of firing, the rear steady rest 30 strikes the rear bolt 32.

(13) The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
