EP1639310B1 - Barricade breaker - Google Patents

Description

The present invention relates to a barricade crusher according to the preamble of patent claim 1.

As is well-known, police and military operations should be adapted to the goals to be achieved in such a way that the property of third parties is not endangered. Often, however, the perpetrators barricade behind such doors behind doors, walls and light armor and defend their position there with all available means.

From DE-A1- 103 03 106, a barricade crusher is already known which breaks through an obstacle with a centrally arranged penetrator and presses an irritant through the perforated barricade with a piston operatively connected to the penetrator.

In practical use, it has been shown that the massively designed penetrator, for example, a door or a wall easily durchschlägt and the irritant (tear gas, capsaicin, etc.) spread quickly in the room behind it and the people there is temporarily incapacitated. However, there is a great danger that penetrating into the room and there continuing to penetrate someone injured or even killed.

It is therefore an object of the invention to provide a barricade crusher, which achieves a high impact on the target with minimal collateral damage and the barricaded persons temporarily safely put out of action without endangering them physically. It is also the task of Invention to break through trained barricades targeted and in tactical use also oblique angle kills without risking rebound.

This object is solved by the features of the claim.

The stated in the claim flange / bottom prevents the full penetration of the penetrator through the barricade so that it inside the target can not cause injury and / or damage to equipment and furniture. The distance between the flange / bottom and the punch-through part is chosen so that the latter breaks through the barricade in any case.

Preference is given to a subcaliber penetrator with propellant levels according to claim 2, since they also achieve the necessary launch acceleration in short projectile tubes, or relatively large propellant charges can thereby be used.

Conveniently are lateral passages, claim 3, in the penetrator, for targeted delivery of the drug in the target area. Alternatively, punch-through parts are conceivable which have axial and radial bursting openings and open under pressure.

Particularly simple is the introduction of an active substance in a charge which ignites pyrotechnic, develops gases and evaporates the active ingredient in the target area either as a mist or as a gas, for example, sublimated. Cf. Claim 4.

The most economical ignition delay consists of a detonating cord ("Stoppine"), which is ignited by the propellant charge, passed over the longitudinal axis of the penetrator, initiates the charge with the active ingredient front. Claim 5.

For safety reasons, a thermal insulation according to claim 6 for guiding the fuse is recommended. The simplest embodiment is a metallic tube in which the fuse is stored centrally with a sufficiently large air gap.

The design of the ignition delay according to claim 7 shows a surprising effect: after the initiation of the propellant this is only on the front, clamped in the active charge. Arrives the projectile in the target before the predetermined delay time (burning time) is reached, then flies this ignition delay or the glowing fuse due to their inertia forward so that their now glowing particles ignite the active charge directly.- Thus, the simplest kind an "inflator", without additional technical measures.

Probably the simplest ignition of the propellant charge is via a percussion fuse, claim 8, although other ignition means depending on the existing projectile tube are conceivable.

Has proven to be a breakthrough part upstream tip according to claim 9.

A replaceable screw-threaded tip according to claim 10 allows the bullet to be optimized for its effect in the target.

The design of the tip according to one of claims 11 or 12 is optimal for a large number of targets.

Cone-shaped tips according to claim 13 have proven especially in barricades of hard woods, as they result in a drilling action.

Sharp-edged tips according to claim 14 allow the tactical use of the projectiles, largely without limiting the firing angle. By inserting elastomers, the bullet can be handled without the risk of injury to the shooter.

Sabot made of soft plastics, cf. Claim 15, cut easily into the trains of projectile tubes and transferred to the penetrator desired for stabilization spin. In particular, sabot made of polyurethane have proven to be useful.

Bullet pipes with a caliber of 40 mm are widespread, so that conventional weapon systems are suitable for the use of the subject invention. As a handgun, flare guns have proven excellent according to claim 16, not least because of their short design.

Hereinafter, embodiments of the invention will be described in detail with reference to drawings.

In Fig. 1, a subcaliber projectile is shown; 1 here is an ignition element, called a percussion detonator, which in a conventional bullet 2 (cartridge) is centered. In a recess of the projectile sleeve 2 propellant charge powder 3 is embedded, in which a fuse 4 (Stoppine: 4-fold) protrudes. This fuse 4 is guided in the axis of the projectile in a metallic central tube 5 and terminates in the upper part of a jacket-shaped penetrator 6. In the cavity of this penetrator 6 active ingredients 7 are incorporated, in the present case, this is a pyrotechnic fog set, which contains known irritants , In the region of the front end of the penetrator 6 are opposing passages 8, which serve as nozzle holes for the exit of the gases of the mist set.

The penetrator 6 is closed at the front by a punch-through part 10 and the rear side by a bottom with flange 13. As a mechanical, non-positive connections serve caulking, local constrictions 9a and 9b of the shell 6a of the penetrator 6, so that it is a closed unit. In the punch-through part 10 is a central internal thread 10a, in which a tip 11 is screwed with rear-side external thread 11a. In the flange 13, three pins 12 are used, which each protrude into a sabot 14. In addition, a cover 15 in the form of a commercially available adhesive tape is indicated in the region of the passages 8, so that the effective charge can not prematurely escape or trickle out with the corresponding active substance.

The function of the projectile according to FIG. 1 is very simple:

If a barricade B is to be bombarded, the bullet-fired projectile will, for example, be converted into a commercial one Light signal gun (HECKLER & KOCH, type HK69A1) used and fired by a shooter more or less perpendicular to the barricade B. The propellant 3 develops a large volume of gas, ignites simultaneously the fuse 4 at the rear and drives the flange 13 under a high gas pressure out of the cartridge; the sabot 14 intersect the trains of the projectile tube and transmit its spin. After leaving the pipe (gun), the sabot 14 tip outwards in the usual way; the penetrator 6 flies in the direction F on the barricade B and breaks through them. In this case, the flange 13 "to hang" on the outer wall W1 of the barricade B, so that the passages 8 protrude beyond the inner wall W2. When shooting was, as described, ignited with the propellant charge 3, the fuse 4, so that these in turn, in turn, with a delay of about 4 sec., At the front of the active charge 7 lights. The resulting gases displace any remaining cover 15 and now prepare via the passages 8 (nozzle holes) inside the room, so that the room immediately fills with fog, which allows the intervention of attacking shooters. The typical outflow time of the mist or smoke is 8 to 10 sec. The effect in the room is of course dependent on its volume and air exchange rate.

The optimum operating distance of the bullet described lies between 2 and 10 m. Theoretically, the 103 mm long, 126 g bullet could fly at a muzzle velocity of 78 m / s up to 235 m. For tactical reasons - bringing active ingredients into a confined space requires further steps to successfully fight or arrest an opponent - appear Use distances in the range of a few meters as very practical.

FIGS. 2 to 4 show the same projectile as FIG. 1, but with different tips 11 chosen according to the intended use:

According to Fig. 2 for use on heavy exterior doors and laminated safety glass. The ratio of the diameter A to A 'depends on the target and can be easily determined by practical experiments.

According to Fig. 3 on light exterior doors, light armor and also on laminated safety glass. Here, the diameter A 'corresponds to the diameter A of the penetrator 6.

According to Fig. 4 for use on doors made of solid wood, wherein the cone 11c is in turn adapted to the target to be penetrated.

By screwing the connection shown in Fig. 1, the desired tips can be easily screwed in, which only has to be taken to ensure that the spin of the projectile acts in the screwing of the tip.

Particularly advantageous is the embodiment of a tip according to Figures 5 and 6, but let these oblique shots (a skewed shot), without the risk of ricochets. This is achieved by concave surfaces 16 and 16 ', cf. FIGS. 5 to 5b and FIGS. 6 to 6b.

The sharp-edged recesses 17 are clearly visible in FIGS. 5a and 6b. At a skewed impact on the barricade B (outer wall W1 according to FIG. 1), the edge penetrates into it and clogs without the penetrator changing the direction of flight F substantially.

The angle α shown in Fig. 5a can be selected within wide limits.

In the figures 5, 5b and 6a elastomers 18 are shown, which facilitate the handling of the projectiles in the form of O-rings, without injury to be feared.

In the same way acts a protective cap 19 as shown in FIG. 6b.

The exemplary embodiments relate to a subcaliber projectile; the subject of the invention is not limited to such.

The propellant used is known per se, it can be adapted within wide limits to the Einsatzkost and the to be achieved breakdown performance.

It is also possible to use charges in the penetrator, which in themselves contain any desired active ingredients which are incorporated in microcapsules and burst on heating and / or gas evolution and release the entrapped substances.

The subject invention can be adapted to the target to be penetrated and systems of any caliber.
