EP4019885B1 - Irritation body with means for adjusting active power - Google Patents

Description

The invention relates to an irritation body, in particular to the possibility of individual adjustment and situation-dependent or situation-dependent adaptation of the number of active masses on site. Active masses are understood to mean bangs, flashes, noises (e.g. whistle signals), etc., i.e. so-called shock effects. Furthermore, the invention deals with a safeguard against accidental triggering of the irritant.

Irritation bodies of this type are used for non-lethal defense against people and are also used to support police operations. They are similar to hand grenades, which are usually detonated manually and then thrown away, but should not form fragments.

The DE 199 44 486 C2 discloses an irritant body for manual ignition and ejection with a cylindrical container which has several compartments running parallel to the central axis of the container and which can accommodate effect charges. The effect charges are ignited using a manually operated ignition device on one side of the cylindrical container. After ignition, all effect charges in the container are ignited one after the other in a time sequence, ie, with a time delay, and fired radially outwards. The one quoted in this document DE 92 13 375 U1 describes an irritation body that provides charge containers for delay times in the compartments to accommodate the respective delay and effect charge. These delay charges with different delay times then ignite the effect charges sequentially.

From the DE 10 2008 058 776 A1 is an irritant, also known as a shock weapon, with an additional effect. By incorporating an additional body into an existing free one An additional effect charge can be integrated individually into the irritant body and thus optionally directly before use, thus increasing the effectiveness.

The DE 10 2010 052 209 A1 characterizes an irritation body that has a modular structure. By choosing the appropriate module with a predetermined chamber size, the performance properties of the irritation body can be varied and increased in a simple manner.

A fuse as a re-fuse for a rocker arm igniter for a hand grenade can be used DE 10 2010 021 685 B4 be removed. This allows you to secure it again after arming the irritant. For this purpose, a profile part with a means is used, the means forming a pin as a safety pin, which is pushed into a safety slot in the rocker arm igniter or igniter head by turning the profile part.

From the EP 2 940 421 A1 a rocker arm igniter is known with an igniter head, which includes a pivotally arranged firing pin acted upon by a firing pin spring, and with a safety bracket which is in the same direction of rotation as the firing pin from a starting position in which it is pressed towards the igniter head, into a firing pin -Release position is pivotally arranged. It is intended here that when the rocker arm igniter is not in use, the firing pin spring is in its unstressed state and is tensioned by a separate cocking lever (Unstored Energy Fuze Head). A tensioning lever that can be actuated from a rest position to a focus position is connected to the firing pin spring via a tensioning lever shaft in such a way that the firing pin spring can only be actuated from its unstressed state to its cocked state when the safety bracket is in its starting position. The firing pin spring can be locked in its tensioned state by means of a safety device.

The shows a locking pin for an irritation body DE 20 2013 003 957 U1 on. This locking pin is located in a direction essentially perpendicular to the pivot axis of a rocker arm.

The WO 94/08200 A1 deals with a shock ammunition with a container that has several compartments, each of which is closed off by covered windows in the container wall. Effect charges that are integrated into the compartments are ignited in a specific time sequence. Several effect charges are introduced without increasing the size. Ignition takes place with an ignition device which has an ignition channel common to all effect charges and in which a delay charge is accommodated. With it The aim is to ignite several active charges in a sequence of several seconds one after the other, ie one behind the other, in order to increase the shock effect.

The WO 2010/044716 A1 discloses an action device for various action effects and an action method. The action device includes at least two action charges for two different action effects, which are integrated into a case. The action effects are arranged one behind the other along a longitudinal axis in the shell. The action charges are themselves placed in a container. The action charges are separate from each other. The action device also includes a further container which is arranged axially around the tubular container. A triggering device is arranged in this container. The container can be rotated about its central axis by means of a rotating element attached to the container. The two containers have gas outlet and gas inlet holes, respectively, which are arranged according to a predetermined pattern. The gas outlet holes and the gas inlet holes are arranged so that when the container is rotated, only gas inlet holes of an action charge overlap with the opposite gas outlet holes. The other action charges are blocked.

The invention has the task of showing a possibility with which an adjustment of the irritating body is possible, in particular on site, and specifically the effect or active power can be individually adjusted.

The task is solved by the features of patent claim 1. Advantageous refinements are shown in the subclaims.

The invention is based on the idea of adjusting the active power of the irritation body by means of a switching mechanism via an igniter head of the irritation body, with which the number of effects can be switched on by igniting the effect charge.

The irritation body has several chambers with ignition holes, usually two, each containing an effect charge. The irritation body also includes a delay charge. The delay charge in turn acts on the effect charge in the chambers via so-called overflow holes and the ignition holes in the chamber.

In a preferred embodiment, the inventive switching mechanism contains the delay charge. This measure ensures that the delay charge has no contact with the chambers in a secured position. This construction offers, among other things: The advantage is that the storage of such irritating bodies in particular becomes more reliable, since the connection between the delay set and the effect charge is interrupted during storage.

For the effect to be effective, the delay charge and effect charge must be aligned with one another through the overflow holes / ignition hole. To assume this functional or effective position, the switching mechanism containing the deceleration set is adjusted. The switching mechanism is adjusted, for example, by turning the igniter head. The switching mechanism has several switching positions, with possible intermediate positions ensuring that no connection is established between the delay charge and the chambers. The number of switching positions depends on the number of effects to be set. If there are four adjustable effects, e.g. 2, 4, 6 and 12, the switching mechanism should have four switching positions. With six different, freely selectable effect variants, such as 1, 2, 4, 10, 12 or 1, 2, 3, 6, 9, 12, six switching positions would then have to be provided.

The turning or switching of the switching mechanism is preferably carried out while simultaneously pressing down the igniter head. This measure has the advantage that the adjustment only takes place under pressure, i.e. consciously. By releasing the igniter head in one of the switching positions, it is returned to its original position. Means can also be integrated to prevent the detonator head from sliding back into its original position in its intermediate positions. This measure is then intended to prevent the irritation body from becoming inoperable, since in the intermediate position there is no functional connection between the delay charge and the effect charge.

The irritation body is also equipped with a built-in safety device that prevents the irritation body from being triggered in a non-functional intermediate position of the rear derailleur. If the switching mechanism is rotated at the same time as the detonator head is pressed down, a first safety device is provided in such a way that a twist-pull pin is only released when the detonator head is locked back into its original, upper and therefore correct position. This securing can be done, for example, by a spring-loaded pressure piece that bridges an air gap between the igniter head and the housing of the irritation body. When changing the active power, e.g. changing the number of bangs, the pressure piece is pressed into the igniter head.

This design allows the use of another fuse, which is pressed into this gap during assembly and keeps the first fuse permanently activated. According to the invention, this second security consists of a plastic clip. In addition, this second safety device prevents the hammer from accidentally hitting the primer by means of a tab that projects into the side of the detonator head. This second backup is only removed immediately before use. It prevents any manipulation of the switching unit and rotating splint.

In order to be able to switch on a different number of chambers, the rear derailleur has several overflow holes on the circumference. The overflow holes are partially connected to one another via one or more grooves also made on the circumference. The groove or grooves can, for example, be integrated in a spiral or cascade-like manner. The expert knows alternatives. The pitch of the spiral or the distances within the cascade (stages) depend on the position of the ignition holes in the chambers with which the corresponding overflow holes are to be brought into functional contact.

The present irritation body, here a so-called multi-bang, allows the effective power to be adjusted individually by adjusting the number of bang, bang-flash and/or lightning effects in particular, which creates several, freely selectable bang variants. In order to achieve an individual adjustment option for the active power of the irritation body, the present invention proposes to integrate a switching mechanism into the irritation body, which enables different chambers within the irritation body to be switched on at the same time to adjust the effect by connecting the individual active masses to form a total active mass. The rear derailleur is formed by a tube and holes and grooves integrated on the circumference, some of which form a functional unit with the holes. The switching mechanism switches on a different number of chambers in the irritation body, whereby the active power can be increased or reduced again.

The invention will be explained in more detail using an exemplary embodiment with a drawing.

In Fig. 1 Shown is an irritation body 10 with an igniter head 1, a housing 2 accommodating the igniter head 1, a rocker arm 3 located on the igniter head 1 and a safety pin 4 securing the rocker arm 3. In this exemplary embodiment, the irritation housing 2 has twelve blow-out openings 5 on the circumference, the perspective view Depiction only six exhaust openings 5 reflects. Such irritating bodies are also called side blowers. The blow-out openings 5 are each assigned a chamber 6, in which an effect charge 7 is contained ( Fig. 2 ). The effect charges 7 in this exemplary embodiment are lightning or bang charges. In this exemplary embodiment, the chambers 6 are integrated into two levels 8, 9 within the irritation body 10. The division is preferably such that six chambers 6 are integrated in the upper level 8 and six chambers 6 in the lower level 9. The chambers 6 of the upper level 8 are preferably arranged offset from one another in the housing 2 to those of the lower level 9.

As an alternative to the side blower and the blow-out openings 5 integrated laterally in the housing 2, further blow-out openings (not shown in detail) can be provided in the bottom and cover of the housing 2, which are connected to the chambers via holes (not shown in detail) guided through the body of the irritation body 10. connected to the exhaust openings in the lid and base. In this combined embodiment, the side blow-out openings 5 would have to be covered by an additional body or an additional housing (e.g. pipe). But there is also the possibility of using an irritation body with chambers similar to that DE 10 2004 059 991 B4 without using side exhaust openings. There are no restrictions here.

A (middle) tube 11 is integrated in the middle of the housing 2 between the chambers 6 ( Fig. 3 ). This center tube 11 forms a switching mechanism of the irritation body 10. In a particularly preferred embodiment, a delay set 12, for example, is pressed into the switching mechanism 11. The rear derailleur 11 or the center tube has one or more bores 13 or one or more grooves or notches 14 on the circumference. The grooves 14 have groove beginnings, usually bores 13, and groove ends 15. These interact with the respective ignition bore 16 of the chambers 6, which are connected to the irritation body 1 and individually dimension its effect. Accordingly, the grooves 13 are spiral-shaped or cascade-shaped. The person skilled in the art knows other geometries for connecting the holes 13 made at different heights/levels in the switching mechanism 11 and the respective ignition hole 16 in the chamber 6. The slope or cascade etc. of the groove 14 depends on the position of the ignition hole 16 of the respective chamber 6 to the associated hole 13 of the switching mechanism 11.

Fig. 4 shows the detonator head 1 in a representation in which the rocker arm 3 is to the left of the detonator head 1 and in a sectional view in which the rocker arm 3 is to the right of this. The rocker arm 3 is secured by the split pin 4 in a known manner and holds a spring-loaded firing pin or striking piece 17 from striking a primer cap 18.

A fuse is marked with 20, which is integrated between the switching mechanism 11 and the body, in particular the detonator head 1. According to the invention, this fuse 20 covers the primer 18. The fuse 20, designed according to the invention as a plastic clip, is integrated into an air gap 22 (approx. 2 mm) between the detonator head 1 and the housing 2 of the irritation body 10 and bridges it. In addition, this fuse 20 has a tab 23 which protrudes laterally into the detonator head 1 and thus covers the primer cap 18. This also prevents the firing pin or hammer 17 from accidentally hitting the primer 18. The firing pin or the striking piece 17 would be able to hit the tab 23 at most if the fuse 20 was present.

Another safety device, not shown in more detail, ensures that the split pin 4 can only be pulled and the rocker arm 3 released in the position in which the detonator head 1 has assumed its starting position. In other states of the detonator head 1, pulling the split pin 4 is impossible. This security, also known as a cotter pin lock, can be implemented, for example, by a spring-loaded pressure piece. This ensures that the split pin 4 can only be pulled in the original or starting position of the detonator head 1 and the rocker arm 3 can be released.

The functioning of the irritation body 10 is as follows:
To adjust the individual active power of the irritation body 10, the switching mechanism 11 containing the delay set 12 is adjusted. The switching mechanism 11 is preferably adjusted by turning the igniter head 1, which is mechanically connected to the switching mechanism 11. The switching mechanism 11 has several switching positions, the number of switching positions depending on the number of effects to be set or the possible combinations of the effect charges 7, for example when selecting 2, 4, 8, 10, 12 effects = one starting position + 4 switching positions.

According to the desired number of effects, the number of chambers 6 are functionally connected to the delay set 12 by twisting. The functional connection of the delay set 12 to the chambers 6 takes place via the corresponding bores 13 and the grooves 14 of the switching mechanism 11, which are aligned with the flow openings 16 of the chambers 6 by turning the switching mechanism 11 (of the igniter head 1). The delay set 12 is ignited after loosening the split pin 4 and striking the igniter 17. The firing pin or hammer / igniter is actually a detonator, i.e. an object with explosives on the primer 18. A slag that forms comes out of the bores 13, which is guided either directly or via the groove 14 to the ignition bore 16 of the connected chambers 6. The metals in the slag enter the chambers 6 via the ignition hole 16 and thus come into contact with the effects 7 and ignite them (eg flash charge). The implemented effect is then released into the environment from the blow-out openings 5.

The turning or switching of the switching mechanism 11 is preferably carried out while simultaneously pressing down the detonator head 1. By releasing the detonator head 1 in one of the predetermined and therefore permissible switching positions, it is returned to its original position. For this purpose, a spring etc. can be provided, which is integrated, for example, below the switching mechanism 11 in the housing 2. Integrating a spring below the igniter head 1 is also conceivable.

The irritation body 10 is secured by the two fuses 20 and the splint lock. The fuse 20 is in turn pressed into the gap 22, for example during assembly. This fuse 20 keeps the second fuse, for the split pin 4, permanently activated. In addition, this fuse 20 prevents the hammer or firing pin 17 from accidentally hitting the primer 18 by means of the tab 23 which protrudes laterally into the detonator head 1. This further fuse 20 is only removed directly before use. It prevents any manipulation of the switching unit (rear derailleur) and the splint 4 (e.g. twist splint). Only after removing the fuse 20 does the split pin lock (pressure lock) release and release the split pin 4.
