Abstract

The invention relates to an igniter (1) with a delay time (Vz) that can be set. The delay time (Vz) can be fixedly defined, or individually and situation-dependently set on-site. In particular, the invention relates to a delay time that can be set for a stun grenade, a hand grenade etc., with options for the individual setting and situation-dependent or situation-contingent customisation of the delay time (Vz), and consequently of the effect of the active compositions in-situ. In order to achieve individual setting options, the invention proposes that at least two different delay times (Vz) can be set. To this end, the igniter (1) has, in a delay section (24), preferably in the fuse head (1'), a relief bore (15) that can be closed or opened.

Description

BESCHREIBUNG  DESCRIPTION
Anzündeinheit mit einstellbarer Verzögerungszeit Ignition unit with adjustable delay time
Die Erfindung bezieht sich auf eine Anzündeinheit mit einer einstellbaren Verzögerungszeit. Die Verzögerungszeit kann fest definiert oder individuell und situationsabhängig vor Ort ein gestellt werden. Insbesondere betrifft die Erfindung eine einstellbare Verzögerungszeit für einen Irritationskörper, eine Handgranate etc. mit der Möglichkeit einer individuellen Ein- stellmöglichkeit und situationsabhängigen bzw. situationsbedingten Anpassung der Verzöge rungszeit, und damit verbunden der Wirkung der Wirkmassen vor Ort. Unter Wirkmassen werden u.a. Knall, Blitz, Geräusche (z.B. Pfeifsignal) etc., verstanden, d.h., sogenannte Schockeffekte, wie auch Sprengstoffe. The invention relates to an ignition unit with an adjustable delay time. The delay time can be defined or set individually and depending on the situation on site. In particular, the invention relates to an adjustable delay time for an irritation body, a hand grenade etc. with the possibility of an individual setting option and situation-dependent or situation-dependent adjustment of the delay time, and associated with the effect of the active masses on site. Under active masses, Bang, flash, noises (e.g. whistle signal) etc., understood, i.e., so-called shock effects, as well as explosives.
Irritationskörper dieser Art dienen zur nicht letalen Abwehr und Verteidigung gegen Personen und werden auch zur Unterstützung bei Polizeieinsätzen eingesetzt. Sie ähneln Handgrana- ten, die in der Regel manuell gezündet und danach weggeworfen werden, jedoch keine Fragmente bilden sollten. Handgranaten haben oft einen letalen Hintergrund. Irritation bodies of this type are used for non-lethal defense and defense against people and are also used to support police operations. They are similar to hand grenades, which are usually fired manually and then thrown away, but should not form fragments. Hand grenades often have a lethal background.
Die DE 199 44 486 C2 offenbart einen Irritationskörper zum manuellen Zünden und Fort- schleudern mit einem zylindrischen Behälter, der mehrere parallel zur Mittelachse des Behäl- ters verlaufende Abteile aufweist, die Effektladungen aufnehmen können. Mit einer manuell betätigbaren Zündeinrichtung an einer Seite des zylindrischen Behälters erfolgt das Zünden der Effektladungen. Nach dem Zünden werden nacheinander alle Effektladungen in dem Behälter in zeitlicher Abfolge, d.h., zeitversetzt, gezündet und radial nach außen abgefeuert. Die in diesem Dokument zitierte DE 92 13 375 U1 beschreibt einen Irritationskörper, der für Verzögerungszeiten in den Abteilen Ladungsbehälter zur Aufnahme der jeweiligen Verzöge- rungs- und Effektladung vorsieht. Durch diese Verzögerungsladungen mit unterschiedlichen Verzögerungszeiten werden durch diese anschließend die Effektladungen sequenziell ge zündet. DE 199 44 486 C2 discloses an irritation body for manual ignition and spinning with a cylindrical container which has a plurality of compartments which run parallel to the central axis of the container and which can take up effect charges. The effect charges are ignited with a manually operated ignition device on one side of the cylindrical container. After the ignition, all the effect charges in the container are fired one after the other in chronological order, ie with a time delay, and are fired radially outwards. DE 92 13 375 U1 cited in this document describes an irritation body which provides charge containers for receiving the respective delay and effect charge for delay times in the compartments. Through these delay charges with different Delay times are then ignited sequentially by these effect charges.
Die Erfindung stellt sich die Aufgabe, eine Möglichkeit aufzuzeigen, mit der insbesondere vor Ort eine Anpassung Verzögerung bzw. Verzögerungszeit erreicht werden kann. The object of the invention is to show a possibility with which an adaptation delay or delay time can be achieved in particular on site.
Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausgestaltungen werden in den Unteransprüchen aufgezeigt. The object is achieved by the features of patent claim 1. Advantageous refinements are shown in the subclaims.
Der Erfindung liegt die Idee zugrunde, die Einstellung der Verzögerungszeit (Vz) derart vorgesehen, dass die Verzögerungsladung bzw. der Verzögerungssatz normal oder verlängert abbrennt. Dieser Idee liegt die Kenntnis zugrunde, dass ein drucklos abbrennender pyrotechnischer Satz langsamer abbrennt als ein unter Druck stehender. The invention is based on the idea of setting the delay time (Vz) in such a way that the delay charge or the delay set burns normally or prolongedly. This idea is based on the knowledge that a non-pressurized pyrotechnic charge burns more slowly than a pressurized one.
Aus der DE 19 56 872 A1 ist ein pyrotechnischer Verzögerungssatz mit einer Brennge- schwindigkeit von max. 5mm/sec. bekannt. Anwendung findet dieser Verzögerungssatz in einem Verzögerungselement für den Sekundenbereich, mit einer Hülse, in der zudem ein Anfeuerungssatz und eine Abfeuerungseinrichtung angeordnet sind. Der Verzögerungssatz weist eine Abfeuerungsbohrung auf. Zusammen mit der Hülse bilden der Anfeuerungssatz und der Verzögerungssatz mit der Abfeuerungsbohrung ein pyrotechnisches Verzögerungselement. Die Abfeuerungsbohrung ist über eine weitere Bohrung im Sockel und eine weitere Bohrung im Kopfstück mit einer Auswerfladung wirkungsverbunden. DE 19 56 872 A1 describes a pyrotechnic delay set with a burning speed of max. 5mm / sec. known. This delay set is used in a delay element for the seconds range, with a sleeve in which a firing set and a firing device are also arranged. The delay set has a firing hole. Together with the sleeve, the firing kit and the delay kit with the firing hole form a pyrotechnic delay element. The firing hole is functionally connected via a further hole in the base and a further hole in the head piece with an ejection charge.
Die DE 10 2012 014 150 A1 offenbart ein Verzögerungselement für eine Munition. Dieses besteht aus einem Röhrchen, einer Hülse, einer Vorspannung und einem in das Röhrchen eingebrachten chemischen Verzögerungssatz. Das Röhrchen weist über einen Teil seiner Länge einen axialen Schlitz auf und ist axial verschiebbar in der Hülse gelagert. Eine schmale Ringfläche der Hülse deckt das Ende des Schlitzes an der Abfeuerseite ab, sodass der Anzündsatz nicht mit dem Verzögerungssatz im Schlitz des Röhrchens in Berührung kommt. Diese Position bedeutet die Ausnutzung der max. Verzögerungszeit. DE 10 2012 014 150 A1 discloses a delay element for an ammunition. This consists of a tube, a sleeve, a preload and a chemical retardation set inserted in the tube. The tube has an axial slot over part of its length and is axially displaceably mounted in the sleeve. A narrow annular surface of the sleeve covers the end of the slot on the firing side so that the primer does not come into contact with the delay set in the tube slot. This position means the utilization of the max. Delay Time.
Gemäß der vorliegenden Erfindung ist hingegen eine sogenannte Entlastungsbohrung vorgesehen, die einen drucklosen Zustand im Anzündgehäuse einstellen kann. Diese Entlastungsbohrung ist daher bevorzugt im Anzündgehäuse vorgesehen. Das Verschließen der Entlastungsbohrung kann in einer einfachsten Variante mit einem Mittel, wie einem Stift, Splint oder dergleichen, in der Entlastungsbohrung erfolgen, der zum öffnen der Entlastungsbohrung aus dieser herausgenommen werden kann. According to the present invention, however, a so-called relief bore is provided, which can set a pressure-free state in the ignition housing. This relief bore is therefore preferably provided in the ignition housing. In the simplest variant, the relief bore can be closed with a means, such as a pin, Splint or the like, take place in the relief bore, which can be removed from the relief bore to open it.
Die Erfindung bezieht sich auf eine Anzündeinheit mit einer einstellbaren Verzögerungszeit. Die Verzögerungszeit kann fest definiert oder individuell und situationsabhängig vor Ort ein- gestellt werden. Insbesondere betrifft die Erfindung eine einstellbare Verzögerungszeit für einen Irritationskörper, eine Handgranate etc. mit der Möglichkeit einer individuellen Ein- stellmöglichkeit und situationsabhängigen bzw. situationsbedingten Anpassung der Verzöge- rungszeit und damit verbunden der Wirkung der Wirkmassen vor Ort. The invention relates to an ignition unit with an adjustable delay time. The delay time can be defined or set individually and depending on the situation on site. In particular, the invention relates to an adjustable delay time for an irritation body, a hand grenade etc. with the possibility of an individual setting option and situation-dependent or situation-dependent adjustment of the delay time and, in connection therewith, the effect of the active masses on site.
Bei einem Zünder eines Irritationskörpers kann das Öffnen der Entlastungsborhung, wenn sich diese im Zündergehäuse bzw. Zünderkopf befindet, auch durch ein geringfügiges Ver- schiebens des Zünderkopfes nach oben gegenüber dem Gehäuse (Zündergehäuse) durch- geführt werden. Dadurch wird ein Entweichen der Verbrennungsgase aus der Verzögerungsstrecke (Vz- Strecke) ermöglicht. In the case of a detonator of an irritation body, the relief bore, if it is located in the detonator housing or detonator head, can also be carried out by slightly moving the detonator head upwards relative to the housing (detonator housing). This enables the combustion gases to escape from the delay line (Vz line).
Bei Wahl eines Mittels, wie eines Stiftes, ist angedacht, dass dieser gezogen oder gedrückt werden kann, um die Entlastungsbohrung freizugeben. Das Verdrehen eines Konturstiftes als Mittel ist eine weitere von vielen Möglichkeiten, die Entlastungsbohrung zu öffnen oder zu verschließen. Die vorgeschlagenen Möglichkeiten sollten jedoch so ausgelegt werden, dass die Entlastungsbohrung durch die Mittel auch wieder verschlossen werden kann. When choosing an agent, such as a pin, it is contemplated that it can be pulled or pressed to expose the relief bore. Twisting a contour pin as a means is another of many options for opening or closing the relief bore. However, the proposed options should be designed so that the relief bore can also be closed again by the means.
Die einstellbare Vz-Zeit kann einfach und bevorzugt in zwei frei wählbaren Varianten ausge- führt sein. Hier lassen sich Verzögerungszeiten von z.B. 0,5s oder 1 ,0s, 1 ,0s oder 1 ,5s etc. einstellen. Weitere Möglichkeiten sind gegeben. The adjustable Vz time can be carried out simply and preferably in two freely selectable variants. Delays of e.g. Set 0.5s or 1, 0s, 1, 0s or 1, 5s etc. There are other options.
Vorgeschlagen wird daher die Möglichkeit einer individuelle Einstellmöglichkeit und situationsabhängigen bzw. situationsbedingten Anpassung der Verzögerungszeit Vz. Diese hat dann beispielsweise auf die Wirkung von Wirkmassen vor Ort Einfluss. Die Einstellmöglich- keit wird dadurch realisiert, dass über eine Entlastungsbohrung zwei unterschiedliche Verzö- gerungszeiten Vz eingestellt werden können. Bei einem Irritationskörper oder einer Hand- granate ist eine Entlastungsbohrung in der Verzögerungsstrecke vorzugsweise im Zünder- kopf vorgesehen, die verschlossen oder geöffnet werden kann. The possibility of an individual setting option and situation-dependent or situation-dependent adaptation of the delay time Vz is therefore proposed. This then has an influence, for example, on the effect of active masses on site. The setting option is realized in that two different delay times Vz can be set via a relief bore. In the case of an irritation body or a hand grenade, a relief bore is provided in the delay section, preferably in the detonator head, which can be closed or opened.
Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden. Es zeigt die einzige Figur eine Darstellung einer Anzündeinheit 1 , hier eines Zünderkopfes, eines nicht näher dargestellten bekannten Irritationskörpers. Diese Figur zeigt den Zünder- kopf V in einer Darstellung, in der ein Kipphebel 3 sich links am Zünderkopf V sowie in einer Schnittdarstellung, in der der Kipphebel 3 sich rechts von diesem befindet. Der Kipphebel 3 ist durch einen Splint 4 in bekannter Art und Weise gesichert und hält einen federbelasteten Schlagbolzen 17 bzw. Schlagstück / Zünder (einen Detonator), also ein Gegenstand mit Explosivstoffen davon ab, auf ein Zündhütchen 18 aufzuschlagen. The invention will be explained in more detail using an exemplary embodiment with a drawing. The sole FIGURE shows an illustration of an ignition unit 1, here an igniter head, of a known irritation body, not shown in detail. This figure shows the igniter head V in a representation in which a rocker arm 3 is located on the left of the igniter head V and in a sectional view in which the rocker arm 3 is located to the right of the latter. The rocker arm 3 is secured by a split pin 4 in a known manner and holds a spring-loaded firing pin 17 or striker / detonator (a detonator), that is, an object with explosives, from hitting an ignition cap 18.
Wie der Figur, rechte Darstellung entnehmbar ist, weist der Zünderkopf G eine Entlastungsbohrung 15 in einer Verzögerungsstrecke 24 auf, die durch einen weiteren Splint, Stift 16 oder dergleichen freigegeben werden kann. As can be seen from the figure on the right, the detonator head G has a relief bore 15 in a delay section 24, which can be released by a further split pin, pin 16 or the like.
Die Entlastungsbohrung 15 befindet sich in der Verzögerungstrecke 24 (Kanal) und diese bevorzugt innerhalb des Zünderkopfes V. The relief bore 15 is located in the delay section 24 (channel) and this is preferably located within the detonator head V.
Die Funktionsweise ist wie folgt: It works as follows:
Die Sicherung der Irritationskörpers erfolgt durch die Sicherungen 20. Die Sicherung 20 wird beispielsweise bei der Montage in den Spalt 22 gedrückt. Zusätzlich verhindert diese Sicherung 20 durch die seitlich in den Zünderkopf 1 ' hereinragende Lasche 23 das unbeabsichtigte Auftreffen des Zünders 17 auf das Zündhütchen 18. Diese weitere Sicherung 20 wird erst direkt vor dem Einsatz entfernt. Sie verhindert daher auch jegliches Manipulieren an der Vz- Verstellung und dem Splint 4 (z.B. Dreh-Splint). Erst nach Entfernen der Sicherung 20 löst sich eine nicht näher dargestellte Drucksicherung und gibt den Splint 4 frei.  The irritation body is secured by the fuses 20. The fuse 20 is pressed into the gap 22 during assembly, for example. In addition, this fuse 20 prevents the unintentional impact of the igniter 17 on the primer 18 by the tab 23 protruding laterally into the detonator head 1 '. This additional fuse 20 is only removed directly before use. It therefore prevents any manipulation of the Vz adjustment and the split pin 4 (e.g. rotary split pin). Only after the fuse 20 has been removed does a pressure fuse, not shown, release and release the split pin 4.
Für die Einstellung der Verzögerungszeit Vz kann der Splint 16 in der Entlastungsbohrung 15 verbleiben oder aus dieser herausgezogen werden. Bei geöffneter Entlastungsbohrung 15 brennt der pyrotechnische Verzögerungssatz 12 drucklos und damit langsamer als unter Druck ab. Das realisiert eine längere Vz gegenüber einer verschlossenen Entlastungsboh- rung 15. Bleibt die Entlastungsbohrung 15 hingegen verschlossen, erfolgt der Abbrand des pyrotechnischen Verzögerungssatzes 12 wie mittels der Menge des Verzögerungssatzes ursprünglich eingestellt, d.h. normal. To set the delay time Vz, the split pin 16 can remain in the relief bore 15 or be pulled out of it. When the relief bore 15 is open, the pyrotechnic delay set 12 burns without pressure and thus more slowly than under pressure. This realizes a longer Vz compared to a closed relief bore 15. If the relief bore 15 remains closed, however, the pyrotechnic delay set 12 is burned off as originally set by means of the quantity of the delay set, i.e. normal.
Dieses Ausführungsbeispiel bezieht sich vorliegend auf einen Irritationskörper. Die Anwen dung der erfinderischen Idee der einfachen Einstellung der Verzögerungszeit ist auf diesen Einsatz jedoch nicht beschränkt. Eine Anwendung bei einer Handgranate ist ebenfalls denkbar. In the present case, this exemplary embodiment relates to an irritation body. The application of the inventive idea of simply setting the delay time is not limited to this use. Use with a hand grenade is also conceivable.
