Description

Self Defense Staff

The invention relates to a self-defense rod for defense against attackers by means of high electrical voltage, consisting of a housing, a handle, external electrodes, an electronic high-voltage circuit accommodated within the rod, together with batteries and a trigger switch.

The basis for the function of such self-defense rods is that touching a high, low-frequency alternating voltage results in a brief paralysis of the nervous system, although there is no danger to the heart or other organs due to the very low current intensity.

In the case of a self-defense rod known from the prior art, it is located on the side thereof Surface of a bifilar wire winding, in such a way that two wires with different voltage potentials lie side by side. When the trigger switch is actuated, a high voltage is applied to this wire winding ^* . The disadvantage of this self-defense rod, however, is that the arrangement of the contact wires described requires the rod to be touched laterally. In addition, the user has no control over the proper functioning of the self-defense rod. Furthermore, it is provided here for the batteries to be accommodated in the part of the rod opposite the handle, but as a result of which there is a cavity here, so that this rod is not impact-resistant and therefore mechanical. Defense is unsuitable.

Starting from a ^' self-defense staff of the type described, the object of the invention is to develop a self-defense staff with which a more effective and secure defense against attackers is possible.

This spaced-apart pairs of electrodes according to the invention by two spaced reached, advantageously a pair of electrodes at the handle opposite tightly sealed end face des.Gehäuses and the second electrode pair of self-adhesive ^'metal foil, especially copper foil, is strip-shaped is arrange on the side surface of the housing. With this design of the self-defense rod according to the invention, the attacker only needs to be touched with the front electrodes, which is in comparison to a lateral one Touch from a greater distance is possible. However, if the attacker grips the self-defense rod, this prevents the second pair of electrodes on the side. The pair of electrodes on the end face according to the invention has the further advantage that when the trigger switch is actuated, arc discharges occur between the electrodes due to the high voltage and the associated high electric field strength. As a result, the proper functioning of the self-defense rod is already indicated optically and acoustically and, moreover, an optical and acoustic deterrent effect is achieved: further advantageous design features of the

Invention are contained in the subclaims and the description below.

«

The invention will be explained in more detail below with reference to the exemplary embodiments illustrated in the drawings. It shows:

1 shows an embodiment of a self-defense rod according to the invention with a round cross section,

2 shows a further embodiment of a self-defense rod according to the invention, which is designed in two parts and collapsible with a rectangular cross section, Fig. 3 is a partial section along the line III-III of FIG. 2 and

4 shows a partial view of an alternative embodiment of the exemplary embodiment according to FIG. 1 with a recessed trigger switch which can be covered by a slide,

5 is a cross section through the upper section of the self-defense rod according to the invention.

The self-defense rod shown in Fig. 1 consists of a housing 1 and an adjoining handle 2, wherein the housing 1 and the handle 2 are advantageously formed in one piece, preferably with a ^' circular cross-section. The surface of the handle piece 2 is provided with knurling or a similar roughening for safe guidance of the self-defense rod. The end face of the housing 1 opposite the handle 2 is advantageously firmly closed by a circular insulating plate 3. According to the invention, this end-side closure plate 3 carries a pair of electrodes 4, whereby advantageously these end-side electrodes 4 consist of metal pins which protrude from the closure plate 3. In the handle 2 opposite the upper third of the rod is according to the invention a second pair Elektroden¬ 5 of self-adhesive metal foil, especially copper foil, streifenförmiσ on the side surface ^'of the housing 1 ange¬ arranged. These metal strips 5 are advantageously arranged parallel to the center axis of the housing and are diametrically opposed to each other. Both pairs of electrodes 4, 5 are connected to an electronic high-voltage circuit, which according to the invention is arranged in the housing 1 adjoining the handle 2. The inside of the

Housing 1 is advantageously filled with casting resin, including the high-voltage circuit. This has the advantage that the self-defense stick according to the invention is extremely impact-resistant and is therefore also ideally suited for mechanical defense against attackers. The batteries required for generating the high voltage are advantageously arranged in the handle 2, which can be closed at the end by a cover 6, preferably by a screw cover.

For secure guidance of the self-defense rod, this screw cap 6 is provided with a hand strap 7. A trigger switch 8 is arranged in the region of the handle piece 2, namely at its end facing the electrodes. By actuating this trigger switch 8, a low-frequency alternating voltage U of approximately 32,000 V is generated by means of the electronic high-voltage circuit. The actuation of the trigger switch 8 is advantageously indicated by a function control lamp 9 in addition to the above-mentioned arcing between the front electrodes 4. According to the invention, this control lamp 9 is arranged above the trigger switch 8 in the wall of the handle piece 2. The advantage of this function control lamp is, on the one hand, that the proper functioning of the self-defense rod is displayed even with short-circuited electrodes, for example while touching an object or an attacker. On the other hand, the control lamp 9 also ensures battery control. If the battery voltage drops below 5 V, for example, the control lamp 9 no longer lights up when the trigger switch 8 is actuated, and the battery must be replaced.

FIG. 2 shows a further embodiment of a self-defense stick according to the invention, the parts corresponding to the exemplary embodiment according to FIG. 1 being designated with the same reference numbers for the self-defense stick for storage and transport, for example in a women's handbag To make it smaller and more compact, it is provided according to the invention that the housing 1 and the handle 2 are made in two pieces and are connected to one another by a hinge 11 so as to be pivotable by 180 °. For this purpose, it is expedient if the housing 1 and the handle 2 have a rectangular cross section. In the hinge 11 opposite side wall of the housing 1 according to the invention is a the handle 2 in the position of use, ie ^', stored in the unfolded state LOCKING interlocking lever 12 is rotatable. For this purpose, an opening 13 is provided in the housing wall, in which the locking lever 12 is mounted by means of an axis of rotation 14 (see FIG. 3). The locking lever 13 can advantageously be latched with a hook-shaped end 15 into a locking opening 16 in the wall of the handle piece 2 when the handle piece 2 is unfolded and for folding the handle piece

2 can be unlocked by means of an actuating piece 17 opposite the hook-shaped end 15.

Through this inventive collapsibility of the handle 2, it is possible to provide protection against unintentional actuation of the trigger switch 8, in that the high-voltage circuit in the housing 1 is supplied with battery voltage advantageously only with the handle 2 folded out and locked in the position of use.

According to Flg. ^' 3 is provided according to the invention that on the battery cover 6 opposite end of the handle 2 two electrical contacts 18 are arranged such that they with two further contacts 19 of the front pair of electrodes 4 opposite end of the housing 1 in the unfolded state of Grip piece 2 are in contact. As soon as the handle 2 is folded in, the contacts 18, 19 are separated, so that the self-defense rod according to the invention can be handled safely and, for example, can be accommodated in a pocket.

4 shows a further possibility of preventing the trigger switch 8 from being actuated inadvertently. The trigger switch 8 According to the invention, recessed in the wall of the handle 2 and advantageously covered by a cover slide 20 arranged displaceably in the wall of the handle 2. In this embodiment, it can also be provided according to the invention that the front electrodes 4 are retractably held in the front closure plate 3 of the housing 1 and are connected to the cover slide 20 via an actuating rod guided within the housing 1 such that they are in the covered state the trigger switch 8 are sunk and protrude from the closure plate 3 in the open state of the trigger switch 8. Thus, the end-face electrodes 4 may be on the one hand not damaged during transport and on the other hand itself polluter no other damage ^• things.

Due to the described advantageous embodiment of the self-defense stick according to the invention, an effective and extremely secure defense against attackers is possible with simultaneous safe and practical handling.

5 shows a further advantageous embodiment of a self-defense rod according to the invention, the same parts as in the previous figures being identified with the same reference numbers. The front electrodes 4 each have branches 22, which are inside the closure plate 3 run. In the embodiment shown, the closure plate 3 is a front end plate of the plug cap 23, which has ribs 24 on the outside of the cap wall, so that it can be inserted into the open end of the housing 1 by clamping. The branches 22 end on the circumferential surface of the closure plate 3 in such a way that the exposed ends are arranged above the lateral electrodes 5. The outer ends of the branches 22 thus form a spark gap with the opposite ends of the electrodes 5. According to the invention, there is therefore no direct, electrically conductive connection between the branches 22 of the electrodes 4 and the side electrodes 5; rather, these parts are separated from one another in the exemplary embodiment shown by an air gap, so that the side electrodes are voltage-free. This configuration according to the invention has the advantage that in the event of continuous contact of the lateral electrodes 5 by enclosing the housing 1, the electrodes are connected to one another so that they can now be live. Flashovers can now build up between the opposite ends of the branches 22 and the electrodes 5 with the desired high voltage, so that new high-voltage shocks are repeatedly given to the person holding the housing in the area of the electrodes 5. It is also within the scope of the invention, also in the front electrodes

Subdivide the electrodes 4 into two electrode sections to form a spark gap. By providing a spark gap between the electrodes and the high-voltage circuit, according to the invention it is achieved that with continuous. Touching the electrodes with an attacker the functionality of the rod vo.ll is retained.

Furthermore, it is within the scope of the invention if the batteries located in the housing are each arranged separately in one-sided, trough-shaped containers, resilient contact elements being contained in these containers, which are conductively connected to the two poles of the battery under a resilient system and at the same time keep the battery jammed in the container. The-

Contact elements are led outwards, the two containers being connectable to one another at the end, advantageously by means of a tongue and groove connection, at the same time through-contacting the batteries in such a way that the two batteries are connected in series. Contacts are arranged on the receptacle for the batteries, which lies furthest inside the housing in the inserted state, which, when inserted, establish a conductive connection with the high-voltage circuit in the housing. On the other container, a flip-up bracket is attached to the end facing the housing opening, on which the interconnected containers can be pulled out of the housing.
