DE9300760U1 - Self-defense device - Google Patents

Description

Self-defense is becoming increasingly important given our rising crime rate. In particular, this involves personal protection, i.e. defense against physical violence.

In this context, one must only think of violence in the open streets and, in particular, violence against women.

The self-defense weapons available on the market today are not only passively usable, but can, on the contrary, even be used to put the victim in a situation of defenselessness.

The purpose and purpose of the invention is therefore to create a defensive weapon that allows one to act purely passively, i.e. to ultimately stop the attacking opponent in his activity.

From nature, we know the so-called skunks from the Mustelidae family, whose glandular secretion from anal glands is sprayed specifically for defense and thus offers effective protection against attacking predators.

One of the main components of the chemical composition of the gland secretion is, for example, 1-butanethiol and, among other substances, thietane, which can be synthesized, whose viscosity is almost the same as that of water and which can therefore be sprayed in a targeted manner, for example, using an appropriate mechanism.

In addition, thietane, for example, has the unpleasant property of causing vomiting and, ultimately, if it comes into contact with the skin, can only be removed after days of effort.

From this point of view, it seems sensible to the author that substances such as thietane or other skunks—or extracts of other marten species or extracts that are purely chemically synthesized as liquids, preferably with an effect similar to that of a liquid—should only be filled by authorized bodies, that the user should be required to provide identification and that the device used should be registered at the same time. In this context, this has the great advantage that in the case of a violent crime, if the person is known to be in possession of such a device, it can be concluded that it was used, so that the strong effect of the substance used marks the perpetrator and ultimately makes it easier to catch him through the manhunt.

The device will now be explained in more detail with reference to claims 1-14 and Figure 1.

This shows

Figure 1 schematically shows a possible

Variant of an application device.

This preferably consists of a tube (1) with a nozzle (2), which in turn is hermetically sealed by a needle (3), in particular by using an O-ring (4). After use, the application device should and can be closed with a sealing cap.

Needle (3) in turn moves in bolt (5), which hits piston (7) through the circular shoulder (6). Piston (7) has a bore (8) that is deflected (9) and always corresponds to the circular recess (6) of bolt (5) via recess (10).

In addition, the tube (1) is slotted (11) so that the handle (trigger) (12) has a defined travel path (11), and the piston (7) is connected to the reservoir (13) via the bore (8), which in a preferred embodiment contains synthesized substances such as thietane.

It should also be mentioned that the piston (7) is of course sealed by the O-rings (14, 15). The reservoir (13) is closed at the back with the piston (16) and O-ring (17), whereby the piston (16) is under tension via the spring (18), which is supported against the base of the screwed-on cap (19).

Special mention should be made of the side channel (20) in the front part of the nozzle, which corresponds to the recess (21) in the bolt (55). In practical use, the handle (12) is pulled back, causing the needle (3) to move backwards and release the nozzle (2,22) via the side channel (20). At the same time, pressure is exerted on the piston (16) via the spring (18) and the substrate (13) to be sprayed is ejected under pressure via the channels (8,9,20,21) and the nozzle part (2,22). The chamber (13) can be refilled by qualified personnel via the valve (23) shown in the symbol. In the variant shown, the device can be used several times, particularly given the fact that when a substance such as thietane is used, a single drop is enough to produce an extremely deterrent effect.

Nevertheless, it should be noted that the device according to Figure 1 represents only one of many possible application examples, that, for example, a device is possible that sprays such substances with propellant gas and that, moreover, in such a variant, the combination of a substance such as thietane with an irritant gas is conceivable.

In addition, it is possible to apply the substance in bursting containers, which in turn can be fired using gas pistols, which at the same time makes it possible to design a combination of irritant gas pistols with corresponding containers such as bullets filled with thietane or similar substances or groups of substances.
