Non-lethal projectile

Guns as they are currently used in the police force have various disadvantages. A wrongly suspect or an innocent one Party involved can be fatally injured. The gun also poses a danger to the police officer if the gun got into the hands of a suspect in a scuffle. After all, due to our legal order, after who is responsible for the conviction and punishment of a perpetrator, the requirement that a suspect if possible should not be hurt.

The most important property of one that can be used for police purposes Weapon is the ability to render someone harmless, but not to kill someone. This property is necessary to prevent suspects from fleeing, defending themselves or committing further crimes.

None of the known weapons meets all of the above requirements . The usability of a rubber truncheon, for example

is limited by the range of the user. The advantage of a rubber club is / that with it a harmless making blow can be performed without the rubber truncheon "penetrating" the body of the offender. So what would be desirable is a long-range device that can strike like a rubber truncheon or otherwise harmlessly can exert a making effect.

The object of the invention is to provide a through a shooting device to create a firable projectile that can render a living, especially human, target harmless without penetrating the target or cause fatal injury. This is achieved by the features specified in claim 1. Beneficial Refinements of the invention are given in the subclaims. .

According to the invention, the projectile is that of a suitable Shooting device can be fired, designed deformable, so that it is during its flight due to centrifugal forces expands radially. This makes a hit of relatively large. Total energy, but relatively smaller Energy per unit area achieved, which is sufficient to render harmless with minimal penetration depth.

The projectile according to the invention has the advantage that the shooting device need not be excessively large and unwieldy, since the projectile initially has a relatively small cross-section. Another advantage of the projectile according to the invention is

it says that it can adapt to the shape of the goal, so that the shot energy extends over a relatively large area of the target can evenly distribute.

Based on the drawing, preferred exemplary embodiments of the Invention explained in more detail. Show it:;

Fig. 1 is a perspective view of a cartridge,

Fig »2 is a side view of a SehießvOrrichtung, wherein the half of the barrel is broken away to make up the arrangement the sleeve to show

3 is a view corresponding to FIG. 2, showing the projectile shortly after firing

Fig. 4 shows the FIGS. 2 and: 3 corresponding view for explanation the arrangement of the various parts after the projectile has emerged from the barrel of the -shot - * - contraption,

Fig. 5 is a view of a projectile in its trajectory has already expanded completely

6 is a view of another embodiment of a Projectile according to the invention.

Fig. 1 shows a cartridge 10 with a sleeve 12, which on a End through a seal 14 and at the other. End by a Primer 16 is closed. The 1.6 '"primer has a clear

dial extending flange 1-8, which is used for positioning purposes.

The primer 1.6 is provided with a counterbore 20 for receiving a

Ignition substance 22 provided ... .... -

Sin spacer 24 has a counterbore 26 for receiving a Charge 28 on. The spacer 24 is used to define the volume the charge and thus to control the kinetic energy transferred to the projectile.

A piston 30, which rests against the inside of the cartridge case "12, stands with. the inner face of the spacer 24 in connection. Its opposite end face rests on a gas seal 32 at. In the exemplary embodiment shown in FIG the piston 30 made of polyethylene and the gas seal 32 made of Felt; however, other, similar materials can also be used will.

A non-lethal projectile 34 is arranged between the gas seal 32 and the seal 14, which projectile conforms to the geometric shape of the Space between the seal 14, the gas seal 32 and the Inner wall of the cartridge case 12 is tightly adapted.

Fig. 2 shows an embodiment of a shooting device 36 with an internally grooved barrel 38, for example a United States Military 4ÖMM Grenade Launcher (M79 or XM-148), in which the cartridge 10 is arranged in the firing position. The ignition needle the reference was made. 36 is in the center line of the primer 22. When a trigger 40 is withdrawn, the firing pin strikes

109849/1357

in a manner known per se on the igniter 22, whereupon the Charge 28 explodes. The cartridge case 12 is in the usual manner in the firing device by the radially extending surface 18 36 withheld. The explosive force of the charge drives the piston 30 against the mouth end of the barrel 38, the projectile and the seal 14 will be entrained. Due to the 38 provided grooves is the projectile 34 in addition to its longitudinal movement impressed a rotary movement.

Pig. 4 illustrates the relationship of the various parts of the cartridge 10 after exiting the barrel 38. The seal 14 and the piston 30 have a much smaller mass than the projectile and therefore detach from the projectile 34. Due to the self-rotation of the projectile 34 and the centrifugal forces caused thereby the projectile 34 expands radially and takes a pancake-like shape.

In Fig. 5, the projectile 34 has reached its maximum radial extension, which is calculated and designed such that the projectile means a minimal risk of injury.

In the preferred embodiment of the invention, the projectile 34 consists of a heavy fabric which is filled with steel shot and is somewhat similar to a bean sack; ⁵ A bullet that can be fired from a US Military 40MM Grenade Launcher M79 weighs a little less than half a pound.

Fig. Β shows another embodiment of a projectile

which is designed as a network. In its radial expansion, the network assumes a shape that is a multiple of its minimum diameter. Weights 36 are attached to the net J> k , which reinforce the rotation caused by the centrifugal force and stabilize the plug path of the projectile. In this case, the projectile is designed in such a way that it wraps itself around the target, thus rendering the target harmless.
