Description

Die vorliegende Erfindung betrifft einen Wirkkörper zur Ausbringung mindestens einer Effektladung sowie einen entsprechenden Wurfkörper, der den vorgenannten Wirkkörper beinhaltet.The present invention relates to an active body for applying at least one effect charge and a corresponding projectile body which contains the aforementioned active body.

Solche Wirkkörper besitzen häufig pyrotechnische Ladungen als Effektladung und sind somit als pyrotechnische Leuchtkörper bzw. als Nebelkörper als eine besondere Form des pyrotechnischen Leuchtkörpers bekannt.Such active bodies often have pyrotechnic charges as effect charges and are therefore known as pyrotechnic luminous bodies or as fog bodies as a special form of pyrotechnic luminous body.

Entsprechende Wirkkörper werden in militärischen Anwendungen benötigt, aber auch in zivilen Anwendung, beispielsweise bei Sicherheitskräften.Corresponding active bodies are required in military applications, but also in civil use, for example by security forces.

Ein entsprechender, erfindungsgemäßer Wirkkörper soll möglichst gleichmäßig abbrennen und somit seine Wirkladung über einen längeren Zeitraum gleichmäßig ausbringen. Dazu ist es zunächst notwendig, dass ein zuverlässiges Anzünden und/oder Zerlegung der Effektladung im Wirkkörper gewährleistet ist. Dieses ist hauptsächlich abhängig von der Verdämmung des Wirkkörpers.A corresponding active body according to the invention should burn as evenly as possible and thus apply its active charge evenly over a longer period of time. To this end, it is first of all necessary that reliable ignition and / or decomposition of the effect charge in the active body is guaranteed. This is mainly dependent on the damming of the active body.

Um die gleichmäßige Ausbringung der Effektladung zu ermöglichen, ist es wichtig, eine möglichst gleichmäßige Aufrechterhaltung des Innendrucks zu gewährleisten. Bei gleichbleibendem Innendruck während des Abbrands wird eine gleichmäßige Ausbringung der Effektladung gewährleistet.In order to enable the uniform discharge of the effect charge, it is important to ensure that the internal pressure is maintained as uniformly as possible. If the internal pressure remains constant during the burnout, a uniform application of the effect charge is guaranteed.

Ein entsprechender Nebelwurfkörper als Wirkkörper ist beispielsweise aus der DE 10 2010 026 641 A1 bekannt. Der dort beschriebene Wirkkörper besitzt zusätzlich zu den bereits genannten Merkmalen eine Verzögerungsladung, welche ein verzögertes Wirksamwerden der Effektladung bewirkt.A corresponding smoke throwing body as an active body is for example from the DE 10 2010 026 641 A1 known. In addition to the features already mentioned, the active body described there has a delay charge, which causes the effect charge to take effect after a delay.

Es hat sich gezeigt, dass ein Ausstoß in großer Höhe zu hohen Aufprallgeschwindigkeiten des Wirkkörpers am Boden führen kann. Dies wiederum kann zu einer Spontanumsetzung der Effektladung führen und/oder zu einem Erlöschen des Wirkkörpers. Somit wird auch kein Effekt mehr aus dem Wirkkörper ausgebracht.It has been shown that an ejection at great heights can lead to high impact speeds of the active body on the ground. This in turn can lead to a spontaneous implementation of the Effect charge and / or lead to an extinction of the active body. Thus, no more effect is brought out from the active body.

Weiterhin ist aus der US 2007/090174 A1 ein Wirkkörper bekannt, welcher eine nichtpyrotechnische Effektladung durch einen lösbaren Deckel ausbringen kann. Die Ausbringung erfolgt hierbei durch Luftverwirbelungen, welche auf den Deckel einwirken und den Wirkkörper so positionieren, dass die Effektladung ausgebracht wird. Dieser Wirkkörper sowie auch die Ausbringungsart ist nicht für pyrotechnische Effektladungen geeignet.Furthermore, from the US 2007/090174 A1 an active body known which can apply a non-pyrotechnic effect charge through a detachable cover. The application takes place here by air turbulence, which act on the cover and position the active body in such a way that the effect charge is applied. This active body and also the type of application are not suitable for pyrotechnic effect charges.

Die aus dem Stand der Technik bekannten Verzögerungselemente, welche dafür sorgen, dass die Entzündung der Effektladung erst nach einer gewissen Zeit geschieht, sind fehleranfällig oder aufgrund von besonderen Anforderungen mit Inhaltsstoffen versehen, welche durch entsprechende Vorgaben nicht mehr auf dem Markt verfügbar sind (Inhaltsstoffe für entsprechende Effektladungen müssen REACh konform ausgeführt sein).The delay elements known from the prior art, which ensure that the ignition of the effect charge only occurs after a certain time, are prone to errors or, due to special requirements, are provided with ingredients that are no longer available on the market due to corresponding specifications (ingredients for corresponding effect charges must be REACh-compliant).

So ist die Aufgabe der vorliegenden Erfindung, einen Wirkkörper zu schaffen, der die Aufprallgeschwindigkeit reduziert und eine zuverlässige Anzündung ohne Verzögerungselemente bietet. Ebenso ist es Aufgabe der vorliegenden Erfindung, einen homogenen und leistungsorientierte Abbrand zu gewährleisten und den Innendruck beim Abbrand der Verkleidung aufrechtzuerhalten.The object of the present invention is to create an active body which reduces the impact speed and offers reliable ignition without delay elements. It is also the object of the present invention to ensure a homogeneous and performance-oriented burn and to maintain the internal pressure during the burn of the cladding.

Diese Aufgaben werden mit den Merkmalen des vorliegenden Hauptanspruchs 1 gelöst, sowie durch den Wurfkörper nach Anspruch 10.These objects are achieved with the features of the present main claim 1, as well as with the throwing body according to claim 10.

So schlägt die Erfindung einen Wirkkörper zur Ausbringung mindestens einer Effektladung vor, wobei diese Effektladung ein Leuchtsatz sein kann, ein Nebelsatz oder weitere Irritationssätze. Ebenfalls können mehrere Effektladungen in einem Wirkkörper vorgesehen sein.Thus, the invention proposes an active body for applying at least one effect charge, wherein this effect charge can be a flare, a smoke set or other irritation sets. Several effect charges can also be provided in one active body.

Die Effektladung ist in dem Wirkkörper angeordnet und wird ausgebracht durch Zerlegung oder Abbrand.The effect charge is arranged in the active body and is applied by breaking it down or burning it off.

Der Wirkkörper besitzt dazu einen umlaufenden Mantel, welcher zwei Enden aufweist. Diese zwei Enden des Mantels sind nun an einem Ende mit einem Deckel abgedeckt und am anderen Ende mit einem Bremsdeckel.For this purpose, the active body has a circumferential jacket which has two ends. These two ends of the jacket are now covered at one end with a cover and at the other end with a brake cover.

Der Deckel ist so ausgeführt, dass mittels ihm die Effektladung angezündet werden kann. Dies kann beispielsweise durch eine dafür vorgesehene Ausstoßladung geschehen.The lid is designed so that the effect charge can be ignited by means of it. This can be done, for example, by means of an ejection charge provided for this purpose.

Dazu ist der Deckel so gestaltet, dass er entweder brennbar ist und somit durch den Abbrand des Deckels auch die Effektladung angezündet werden kann. In einer besonderen Ausführungsform ist jedoch mindestens eine Anzündbohrung im Deckel vorgesehen, durch welche die Effektladung im Wirkkörper hindurch angezündet werden kann.For this purpose, the lid is designed in such a way that it is either flammable and thus the effect charge can also be ignited when the lid burns off. In a special embodiment, however, at least one ignition hole is provided in the cover, through which the effect charge in the active body can be ignited.

Bei Nutzung eines brennbaren Deckels ist dafür zu sorgen, dass die Ausbringung der Effektladung an der dem Deckel abgewandten Seite des Mantels geschieht. Dafür müssen weitere Elemente auf der Seite des Mantels mit dem Deckel vorgesehen sein, welche eine Ausbringung in Richtung Deckel verhindern.If a flammable lid is used, it must be ensured that the effect charge is applied to the side of the shell facing away from the lid. For this purpose, further elements must be provided on the side of the shell with the lid, which prevent it from being discharged in the direction of the lid.

In einer weiteren besonderen Ausführungsform sind die Anzündbohrungen so gestaltet, dass sie radial umlaufend am Deckel angeordnet sind. Dazu können die Anzündbohrungen auf einer Kreislinie angeordnet sein und vorzugsweise als durchgehende Ausnehmung ausgeführt sein.In a further particular embodiment, the ignition bores are designed in such a way that they are arranged radially circumferentially on the cover. For this purpose, the ignition bores can be arranged on a circular line and preferably designed as a continuous recess.

Das dem Deckel gegenüberliegende Ende des Mantels wird mit einem Bremsdeckel abgedeckt. Der Bremsdeckel weist mindestens ein Loch auf und umfasst eine durch das Loch hindurch geführte Bremsschlaufe.The end of the jacket opposite the cover is covered with a brake cover. The brake cover has at least one hole and comprises a brake loop guided through the hole.

Die Bremsschlaufe ist bevorzugterweise aus einem gewebten Material gefertigt und somit flexibel gestaltet. Die Enden der Bremsschlaufe sind am Wirkkörper befestigt, bevorzugterweise am Mantel des Wirkkörpers.The brake loop is preferably made of a woven material and is therefore designed to be flexible. The ends of the brake loop are attached to the active body, preferably on the jacket of the active body.

Der Bremsdeckel ist derart an der Bremsschlaufe befestigt, dass er lösbar am Mantel angeordnet ist und sich bei Lösung vom Mantel vom Wirkkörper entfernen kann. Die maximale Entfernung des Bremsdeckels wird durch die Bremsschlaufe begrenzt, da durch das Durchführen der Bremsschlaufe durch das Loch des Bremsdeckels der Bremsdeckel in einer maximalen Auslenkung von der Bremsschlaufe gehalten wird.The brake cover is attached to the brake loop in such a way that it is detachably arranged on the jacket and can move away from the active body when it is detached from the jacket. The maximum distance of the brake cover is limited by the brake loop, since the brake cover is held in a maximum deflection by the brake loop by passing the brake loop through the hole in the brake cover.

In einer bevorzugten Ausführungsform sind mehrere Löcher im Bremsdeckel vorgesehen, sodass die Bremsschlaufe durch diese Löcher hindurchgeführt werden kann. In diesem Falle rutscht der Bremsdeckel entlang der Bremsschlaufe beim Lösen vom Mantel des Wirkkörpers.In a preferred embodiment, several holes are provided in the brake cover so that the brake loop can be passed through these holes. In this case, the brake cover slips along the brake loop when it is released from the jacket of the active body.

Bei Verwendung mehrerer Löcher im Bremsdeckel kann die Brennstoffe mäanderförmig durch diese hindurchgeführt werden.If several holes are used in the brake cover, the fuel can be guided through them in a meandering manner.

Die Bremsschlaufe besteht bevorzugter Weise aus einem gewebten Material, kann aber aus jedem flexiblem Material bestehen. Die Löcher im Bremsdeckel können so gestaltet sein, dass sie bei der Bewegung entlang der Bremsschlaufe eine Bremskraft auf die Bewegung des Bremsdeckels ausüben. Dazu können die Löcher entsprechend schmal gestaltet sein oder Klemmelemente beinhalten. Durch diese Ausführungsform kann der Deckel zunächst auf dem Mantel gehalten werden und löst sich erst vom Mantel beim Überwinden der Bremskraft.The brake loop is preferably made of a woven material, but can be made of any flexible material. The holes in the brake cover can be designed in such a way that, when moving along the brake loop, they exert a braking force on the movement of the brake cover. For this purpose, the holes can be designed correspondingly narrow or contain clamping elements. With this embodiment, the cover can initially be held on the jacket and only detaches from the jacket when the braking force is overcome.

Es wird vorgeschlagen, den Deckel durch Verbindungselemente mit dem Wirkkörper zu verbinden. Diese Verbindungselemente können in einer bevorzugten Ausführungsform durch Verstiftung ausgeführt sein. Hierzu sind Ausnehmungen am Mantel vorgesehen, in welche Stifte des Deckels eingreifen können.It is proposed to connect the cover to the active body by connecting elements. In a preferred embodiment, these connecting elements can be designed by pinning. For this purpose, recesses are provided on the jacket, into which pins of the cover can engage.

Die Erfindung schlägt weiterhin einen Wurfkörper vor, bestehend aus einem Gehäuse, welches mindestens zwei Gehäuseelemente aufweist. Im Inneren des Gehäuses ist erfindungsgemäß ein Wirkkörper, wie zuvor beschrieben, angeordnet.The invention further proposes a projectile body consisting of a housing which has at least two housing elements. According to the invention, an active body, as described above, is arranged in the interior of the housing.

Die Gehäuseelemente sind bevorzugterweise durch eine lösbare Verbindung verbunden und können bei Aufbringung einer gewissen Kraft voneinander gelöst werden.The housing elements are preferably connected by a releasable connection and can be released from one another when a certain force is applied.

In einem solchen erfindungsgemäßen Wurfkörper wird eine Ausstoßladung vorgeschlagen. Diese Ausstoßladung ist auf der Seite im Gehäuse angeordnet, auf welcher sich der Deckel des Wirkkörpers befindet. Mit Hilfe dieser Anordnung kann über die Ausstoßladung zum einen die vorgenannte Kraft auf die Gehäuseelemente wirken, sodass diese sich lösen. Zum anderen kann die Ausstoßladung durch die oben genannten Merkmale des Deckels die Effektladung anzünden. Zuletzt kann die Ausstoßladung ebenfalls eine Kraft auf den Wirkkörper ausüben.In such a projectile body according to the invention, an ejection charge is proposed. This discharge charge is arranged on the side in the housing on which the cover of the active body is located. With the aid of this arrangement, on the one hand, the aforementioned force can act on the housing elements via the ejection charge, so that they are released. On the other hand, the ejection charge can ignite the effect charge through the above-mentioned features of the lid. Finally, the ejection charge can also exert a force on the active body.

Erfindungsgemäß besteht eine solche Ausstoßladung ebenfalls aus einen pyrotechnischen Satz, welcher durch geeignete Mittel gezündet werden kann.According to the invention, such an ejection charge also consists of a pyrotechnic charge which can be ignited by suitable means.

Bei Zündung der Ausstoßladung wirkt nun eine Kraft auf den Wirkkörper und damit auch auf das Gehäuse des Wurfkörpers. Durch diese Kraft wird zum einen die Verbindung der Gehäuseelemente gelöst und zum anderen wird der Wirkkörper entgegen der Flugrichtung des Wurfkörpers beschleunigt.When the ejection charge is ignited, a force acts on the active body and thus also on it the housing of the projectile body. On the one hand, this force releases the connection between the housing elements and, on the other hand, the active body is accelerated against the flight direction of the projectile body.

Da sich nach Lösen der Verbindung der Gehäuseelemente der Wirkkörper nicht mehr im Inneren des Gehäuses des Wurfkörpers befindet, wirken äußere Umweltbedingungen auf ihn ein, wie beispielsweise der Luftwiderstand, welcher durch die Flugbewegung auf den Wirkkörper einwirkt.Since the active body is no longer located in the interior of the housing of the projectile after the connection of the housing elements has been loosened, external environmental conditions act on it, such as the air resistance which acts on the active body through the flight movement.

Durch diese Umweltbedingungen wird der Bremsdeckel vom Mantel des Wirkkörpers gelöst und bewegt sich entlang der Bremsschlaufe, bis er von dieser in einer Endposition gehalten wird.As a result of these environmental conditions, the brake cover is released from the jacket of the active body and moves along the brake loop until it is held in an end position by the latter.

In einer besonderen Ausführungsform können zusätzliche Vorsprünge am Bremsdeckel vorgesehen sein, um die Kraft der Luft auf den Bremsdeckel zu verstärken. In seiner Endposition an der Bremsschlaufe des Wirkkörpers wirkt der Bremsdeckel nun wie eine Art Fallschirm auf den Wirkkörper und sorgt somit dafür, dass durch den Luftwiderstand die Fallgeschwindigkeit des Wirkkörpers merklich verringert wird.In a particular embodiment, additional projections can be provided on the brake cover in order to increase the force of the air on the brake cover. In its end position on the brake loop of the active body, the brake cover now acts like a kind of parachute on the active body and thus ensures that the falling speed of the active body is noticeably reduced due to the air resistance.

Durch das Anzünden der Effektladung durch die Ausstoßladung ist kein Verzögerungselement mehr notwendig.When the effect charge is ignited by the ejection charge, a delay element is no longer necessary.

In der Ausführungsform mit den vorgenannten Anzündbohrungen im Deckel, sind diese so zu dimensionieren, dass eine direkte Anzündung der Effektladung zuverlässig stattfinden kann. Da der Verbleib des Deckels auf dem Körper während der gesamten Abbranddauer gewährleistet ist, garantiert dies eine homogene und leistungsstarke Effektausbringung.In the embodiment with the aforementioned ignition bores in the cover, these are to be dimensioned so that direct ignition of the effect charge can take place reliably. Since the lid remains on the body during the entire burning time, this guarantees a homogeneous and powerful effect.

Dadurch, dass kein Verzögerungssatz mehr benötigt wird, ist die REACh-Konformität entsprechend einzuhalten und eine sichere Funktion des Wirkkörpers gewährleistet, da ein möglicherweise fehleranfälliges Element, nämlich der Verzögerungssatz, entfallen kann.The fact that a delay rate is no longer required means that REACh conformity must be complied with accordingly and reliable functioning of the active body is ensured, since an element that may be prone to errors, namely the delay rate, can be omitted.

Das Gehäuse des erfindungsgemäßen Wurfkörpers besteht aus mindestens zwei Gehäuseelementen 6, welche lösbar miteinander verbunden sind, um das Gehäuse zu bilden.The housing of the projectile body according to the invention consists of at least two housing elements 6 which are detachably connected to one another in order to form the housing.

In Längsrichtung des Wirkkörpers 1 wird der Wirkkörper in einer Richtung durch einen Bremsdeckel 4 begrenzt sowie in der anderen Richtung durch einen Deckel 3. An dem Wirkkörper 1 ist weiterhin eine Bremsschlaufe 5 vorgesehen, welche durch Löcher an dem Bremsdeckel 4 hindurchgeführt sind.In the longitudinal direction of the active body 1, the active body is limited in one direction by a brake cover 4 and in the other direction by a cover 3. A brake loop 5 is also provided on the active body 1, which is passed through holes on the brake cover 4.

Auf der Seite des Deckels 3 im Gehäuse des erfindungsgemäßen Wurfkörpers ist eine Ausstoßladung 7 vorgesehen. Die Ausstoßladung 7 ist in Flugrichtung 8 des Wurfkörpers angeordnet.An ejection charge 7 is provided on the side of the cover 3 in the housing of the projectile body according to the invention. The ejection charge 7 is arranged in the direction of flight 8 of the projectile.

Die Gehäuseelemente 6 sind lösbar miteinander verbunden, sodass bei Einwirkung einer Kraft auf die Gehäuseteile 6 die Verbindung gelöst wird und der Wirkkörper 1 aus dem Gehäuse des Wurfkörpers austreten kann.The housing elements 6 are detachably connected to one another so that when a force acts on the housing parts 6, the connection is released and the active body 1 can emerge from the housing of the projectile body.

Zur Erzeugung einer solchen Kraft ist die Ausstoßladung 7 vorgesehen. Bei Zündung der Ausstoßladung 7 durch geeignete Mittel wird eine Kraft auf den Wirkkörper 1 ausgeübt und auch auf die Gehäuseelemente 6. Die Ausübung der Kraft auf die Gehäuseelemente 6 kann unmittelbar durch die Ausstoßladung erfolgen oder mittelbar durch die Kraftübertragung durch den Wirkkörper 1.The discharge charge 7 is provided to generate such a force. When the ejection charge 7 is ignited by suitable means, a force is exerted on the active body 1 and also on the housing elements 6.

Gleichzeitig zur Krafterzeugung sorgt die Ausstoßladung 7 für ein Anzünden der Effektladung im Wirkkörper 1. Dazu ist der Deckel 3 so gestaltet, dass die Ausstoßladung 7 die Effektladung anzünden kann, bevorzugterweise sind dazu Anzündbohrungen im Deckel 3 vorgesehen.At the same time as generating the force, the ejection charge 7 ignites the effect charge in the active body 1. To this end, the cover 3 is designed so that the ejection charge 7 can ignite the effect charge; ignition bores are preferably provided in the cover 3 for this purpose.

Durch die von der Ausstoßladung 7 erzeugte Kraft wird nun der Wirkkörper 1 aus dem Wurfkörper entgegen der Flugrichtung 8 des Wurfkörpers ausgestoßen.As a result of the force generated by the ejection charge 7, the active body 1 is now ejected from the projectile body against the flight direction 8 of the projectile body.

Nach Ausstoßen des Wirkkörpers 1 unterliegt dieser nun den Umweltbedingungen während des Fluges des Wirkkörpers 1. Somit wirkt der während des Flugs vorhandene Luftwiderstand auf den Bremsdeckel 4 des Wirkkörpers 1. Da der Bremsdeckel 4 lösbar am Wirkkörper 1 befestigt ist, wird er nun entgegen der Flugrichtung 8 bewegt und durch die Durchführung der Bremsschlaufe 5 durch den Bremsdeckel 4 von der Bremsschlaufe 5 in einer Endposition gehalten.After the active body 1 is ejected, it is now subject to the environmental conditions during the flight of the active body 1. Thus, the air resistance present during the flight acts on the brake cover 4 of the active body 1. Since the brake cover 4 is releasably attached to the active body 1, it is now against the direction of flight 8 moved and held by the brake loop 5 in an end position by the implementation of the brake loop 5 through the brake cover 4.

Figur 2 zeigt dazu einen erfindungsgemäßen Wirkkörper 1 nach Ausbringung aus dem Wurfkörper. Figure 2 shows an active body 1 according to the invention after being deployed from the projectile body.

Der erfindungsgemäße Wirkkörper 1 ist hierbei durch einen Mantel 9 umhüllt, wobei die Mantelenden durch den Bremsdeckel 4 und den Deckel 3 begrenzt werden. Der Mantel 9 sorgt hierbei, unter anderem, für die Verdämmung der Effektladung.The active body 1 according to the invention is here encased by a jacket 9, the jacket ends being delimited by the brake cover 4 and the cover 3. The jacket 9 ensures, among other things, for the damming of the effect charge.

Wirkt nun die genannte Luftreibung auf den Bremsdeckel 4 wird dieser entlang der Bremsschlaufe 5 entgegen der Flugrichtung bewegt. Zu sehen ist dies in Figur 3.If the air friction mentioned now acts on the brake cover 4, it is moved along the brake loop 5 against the direction of flight. This can be seen in Figure 3 .

In der Endposition, in welcher der Bremsdeckel 4 von der Bremsschlaufe 5 gehalten wird, wirkt der Deckel nun wie ein kleiner Fallschirm durch die Luftreibung entgegen der Flugrichtung auf den Wirkkörper 1. Der Wirkkörper 1 wird somit gebremst. Dadurch wird dem eingangs erwähnten, negativen Effekt eines zu schnellen Aufschlags des Wirkkörpers 1 auf den Boden entgegengewirkt.In the end position in which the brake cover 4 is held by the brake loop 5, the cover now acts like a small parachute due to the air friction against the direction of flight on the active body 1. The active body 1 is thus braked. This counteracts the negative effect mentioned at the beginning of an excessively rapid impact of the active body 1 on the ground.

Der Deckel 3 ist durch geeignete Verbindungselemente 10 fest mit dem Mantel 9 des Wirkkörpers 1 verbunden. Diese Verbindungselemente 10 können beispielsweise Stifte sein, welche in dafür vorgesehene Ausnehmungen im Mantel 9 des Wirkkörpers 1 eingreifen können. Ebenso sind aber auch Rastverbindungen oder Klebverbindungen denkbar.The cover 3 is firmly connected to the jacket 9 of the active body 1 by means of suitable connecting elements 10. These connecting elements 10 can, for example, be pins which can engage in recesses provided for this purpose in the jacket 9 of the active body 1. However, latching connections or adhesive connections are also conceivable.

Um das Anzünden der Effektladung im Wirkköper 1 durch die Ausstoßladung 7 zu ermöglichen, können, wie in Figur 4 gezeigt, Anzündbohrungen 11 vorgesehen sein. Mindestens eine solche Anzündbohrung 11 ist notwendig, um das Anzünden der Effektladung durch den Deckel 3 hindurch zu ermöglichen.To enable the effect charge in the active body 1 to be ignited by the discharge charge 7, as in FIG Figure 4 shown, ignition bores 11 may be provided. At least one such ignition hole 11 is necessary in order to enable the effect charge to be ignited through the cover 3.

Figur 5 zeigt dazu noch einmal die Durchführung 12 der Bremsschlaufe 5 durch den Bremsdeckel 4. Gezeigt sind hierbei zwei Löcher im Bremsdeckel 4. Es können hierbei auch mehrere Löcher vorgesehen sein. Bevorzugter Weise wird dann die Bremsschlaufe 5 mäanderförmig durch die Löcher im Bremsdeckel 4 hindurchgeführt. Figure 5 shows again the passage 12 of the brake loop 5 through the brake cover 4. Two holes in the brake cover 4 are shown here. Several holes can also be provided here. The brake loop 5 is then preferably guided in a meandering manner through the holes in the brake cover 4.

Die Löcher im Bremsdeckel 4 können so gestaltet sein, dass sie eine gewisse Reibkraft auf die Bremsschlaufe 5 ausüben. Somit ist es möglich, den Bremsdeckel 4 an dem einen Ende des Mantels 9 zu halten und die benötigte Luftreibung zur Bewegung des Bremsdeckels 4 entlang der Bremsschlaufe 5 einzustellen.The holes in the brake cover 4 can be designed so that they exert a certain frictional force on the brake loop 5. It is thus possible to hold the brake cover 4 at one end of the jacket 9 and to set the air friction required to move the brake cover 4 along the brake loop 5.

Die vorliegende Erfindung ist nicht auf die vorgenannten Merkmale beschränkt. Vielmehr sind weitere Ausführungsformen denkbar. So kann die Bremsschlaufe aus Gummi bestehen, die Ausstoßladung elektrisch wirken oder der Deckel brennbar gestaltet sein. Im Falle eines brennbaren Deckels sind jedoch Maßnahmen notwendig, um die Ausbringung der Effektladung in Flugrichtung zu verhindern und lediglich entgegen der Flugrichtung sicherzustellen.The present invention is not limited to the aforementioned features. Rather, further embodiments are conceivable. The brake loop can be made of rubber, the discharge charge can act electrically or the cover can be designed to be combustible. In the case of a flammable lid, however, measures are necessary to prevent the discharge of the effect charge in the direction of flight and only to ensure against the direction of flight.
