Description

Die vorliegende Erfindung betrifft eine Anzündeinrichtung für Munition mit mechanischer Zündvorrichtung. Diese ist insbesondere zum fernbedienbaren Anzünden von Munition geeignet. Die mechanische Zündvorrichtung kann dabei insbesondere als Zündhütchen ausgeführt sein. Entsprechend wird ein mechanisches Schlagstück dann dazu verwendet, die Zündvorrichtung zu aktivieren und die Zündung der Munition durchzuführen.The present invention relates to an ignition device for ammunition with a mechanical ignition device. This is particularly suitable for the remote-controlled ignition of ammunition. The mechanical ignition device can in particular be designed as a primer cap. Correspondingly, a mechanical hammer is then used to activate the ignition device and to ignite the ammunition.

Entsprechende Einrichtung werden in unterschiedlichen Waffenarten für unterschiedliche Munition benötigt. Dies reicht von handgehaltenen Waffen bis hin zu fest montierten Waffenstationen.Corresponding facilities are required in different types of weapons for different ammunition. This ranges from hand-held weapons to permanently mounted weapon stations.

Solche Einrichtungen zum Zünden von Munition mit Anzündelement arbeiten zum überwiegenden Teil mit mechanisch vorgespannten Schlagstücken. Dazu gehören ein fernbedienbarer Auslösemechanismus und ein fernbedienbares Sicherungssystem, welche die unbeabsichtigte Schussabgabe verhindern sollen. Durch das Vorspannen von Schlagstücken ist jedoch nicht ausgeschlossen, dass in Folge einer Fehlbedienung eine Schussabgabe erfolgen kann, da die benötigte Energie für den Zündimpuls durch die Vorspannung abrufbar bereit ansteht. Entsprechende Einrichtungen sind beispielsweise aus der CH 711 375 A2 bekannt. Offenbart ist eine separate Lösung zum Vorspannen des Schlagstücks, zum Auslösen des Schlagstücks und zum Sichern des Schlagstücks. Hierbei wird mithilfe eines Aktuators das Schlagstücken betrieben. FR 1 419 970 A offenbart eine Vorrichtung gemäß das Oberbegriffs des Anspruchs 1.Such devices for igniting ammunition with an ignition element work predominantly with mechanically preloaded strikers. This includes a remote-controlled trigger mechanism and a remote-controlled safety system, which are intended to prevent unintentional firing. However, the pretensioning of strikers does not rule out the possibility of a shot being fired as a result of incorrect operation, since the energy required for the ignition pulse is available and can be called up by the pretensioning. Corresponding facilities are, for example, from CH 711 375 A2 known. Disclosed is a separate solution for pretensioning the hammer, for releasing the hammer and for securing the hammer. The hammer is operated with the aid of an actuator. FR 1 419 970 A discloses an apparatus according to the preamble of claim 1.

Aus der EP 2 282 157 B1 ist dazu eine fernsteuerbare Spannvorrichtung für Maschinengewehre bekannt, wobei ein Kettenspanner dazu genutzt wird, eine entsprechende Spannung in der Vorrichtung zu realisieren.From the EP 2 282 157 B1 For this purpose, a remotely controllable tensioning device for machine guns is known, a chain tensioner being used to implement a corresponding tension in the device.

Bei den vorgenannten Lösungen ergibt sich das Problem, dass die in der Einrichtung befindlichen Schlagstücke Vibrationen und Schocken ausgesetzt sein können, beispielsweise bei Transport oder Fahrt der Waffe durch Gelände. In Abhängigkeit der Art des Aktuators kann sich die Waffe dabei in einem nicht sicher definierten Zustand befinden und es kann vorkommen, dass ein unabsichtliches Anzünden der Munition geschieht.With the aforementioned solutions, the problem arises that the strikers located in the device can be exposed to vibrations and shocks, for example when the weapon is being transported or driven through terrain. Depending on the type of actuator, the weapon can be in a state that is not reliably defined and it can happen that the ammunition is unintentionally ignited.

Es besteht somit das Problem einer unzureichenden Sicherheit der Einrichtung. Die vorliegende Erfindung nimmt sich dieses Problems an und schlägt eine Lösung vor.There is thus a problem of insufficient security of the device. The present invention addresses this problem and proposes a solution.

Aufgabe der vorliegenden Erfindung ist somit, eine Anzündeinrichtung für Munition mit mechanischer Zündvorrichtung bereitzustellen, welche zuverlässig funktioniert und eine gegenüber dem Stand der Technik verbesserte Sicherheit gegen unabsichtliches Anzünden der Munition bietet. Diese Aufgabe wird mit den Merkmalen des vorliegenden Hauptanspruchs gelöst. Demnach wird eine Einrichtung zum insbesondere fernbedienbaren Anzünden von Munition vorgeschlagen, mit einer Zündvorrichtung und einem Schlagstück. Vorzugsweise wird die Zündvorrichtung als Zündhütchen ausgeführt. Das vorgenannte Schlagstück ist als mechanisches Schlagstück ausgeführt, welches auf die Zündvorrichtung einwirken kann und die Zündvorrichtung dazu bringt, das Anzünden der Munition vorzunehmen.The object of the present invention is therefore to provide an ignition device for ammunition with a mechanical ignition device which functions reliably and offers improved security against unintentional ignition of the ammunition compared to the prior art. This object is achieved with the features of the present main claim. Accordingly, a device for igniting ammunition, in particular remotely controllable, is proposed, with an ignition device and a hammer. The ignition device is preferably designed as a primer cap. The aforementioned striking piece is designed as a mechanical striking piece which can act on the ignition device and cause the ignition device to ignite the ammunition.

Weiterhin beinhaltet die erfindungsgemäße Einrichtung einen bewegbaren Umlenkhebel, an welchem das Schlagstück angeordnet ist.Furthermore, the device according to the invention contains a movable deflection lever on which the hammer is arranged.

Erfindungsgemäß ist in der Einrichtung eine Schlagmasse längsbeweglich gelagert und kann mehrere Positionen durch ihre Bewegbarkeit einnehmen, mindestens jedoch eine Ruheposition und eine Aktivierungsposition. Die Längsbewegung findet dabei parallel zur Mittelachse der Einrichtung statt.According to the invention, a striking mass is mounted in the device in a longitudinally movable manner and can assume several positions due to its mobility, but at least one rest position and one activation position. The longitudinal movement takes place parallel to the central axis of the device.

Weiterhin ist erfindungsgemäß der Umlenkhebel so ausgeführt, dass die Schlagmasse bei ihrer Bewegung den Umlenkhebel in eine Bewegung, bevorzugt eine Drehbewegung, versetzen kann. Bei der Bewegung des Umlenkhebels kann somit die Schlagmasse mit dem Umlenkhebel in Wirkverbindung treten, um die vorgenannte Bewegung auszuführen. Bevorzugt geschieht dies bei der Bewegung der Schlagmasse aus der Ruheposition in die Aktivierungsposition.Furthermore, according to the invention, the deflection lever is designed such that the striking mass can set the deflection lever in motion, preferably a rotary movement, when it is moved. During the movement of the reversing lever, the striking mass can thus come into operative connection with the reversing lever in order to carry out the aforementioned movement. This is preferably done when the striking mass is moved from the rest position into the activation position.

Weiterhin ist erfindungsgemäß eine Sicherung vorgesehen, welche die Bewegung des Umlenkhebels behindern kann. Da der Umlenkhebel mit dem Schlagstück verbunden ist, wird also auch die Bewegung des Schlagstücks durch die Sicherung behindert. Die Behinderung verhindert die Bewegung der Sicherung zumindest teilweise und zwar derart, dass das Schlagstück nicht mit der Zündvorrichtung in Wirkverbindung treten kann. Dadurch entsteht eine erhebliche Sicherheit gegen unabsichtliches Anzünden der Munition.Furthermore, a safety device is provided according to the invention, which can hinder the movement of the reversing lever. Since the lever is connected to the hammer, the movement of the hammer is also hindered by the safety device. The obstruction prevents the movement of the fuse at least partially in such a way that the hammer cannot come into operative connection with the ignition device. This creates considerable security against unintentional ignition of the ammunition.

Hierzu wird in einer bevorzugten Ausführungsform vorgeschlagen, dass die Sicherung als Welle ausgeführt wird und in einer Führung der Schlagmasse geführt wird. Die Welle umfasst dabei eine Ausnehmung, welche die Bewegung des Umlenkhebels derart erlauben kann, dass das Schlagstück in Wirkverbindung mit der Zündvorrichtung treten kann. Die Welle kann jedoch derart gedreht oder verschwenkt werden, dass die Bewegung des Umlenkhebels eingeschränkt wird, so dass sie nicht in Wirkverbindung mit der Zündvorrichtung treten kann.For this purpose, it is proposed in a preferred embodiment that the fuse is designed as a shaft and is guided in a guide of the impact mass. The shaft comprises a recess which can allow the movement of the reversing lever in such a way that the hammer can come into operative connection with the ignition device. However, the shaft can be rotated or pivoted in such a way that the movement of the reversing lever is restricted so that it cannot come into operative connection with the ignition device.

In einer besonderen Ausführungsform ist ein Gehäuse für die Einrichtung vorgesehen, welche mittels eines Gehäusedeckels verschließbar gestaltet ist. Die Einrichtung kann bei geöffnetem Gehäusedeckel in das Gehäuse eingebracht werden und dort auch gewartet werden. Durch den Gehäusedeckel kann das Gehäuse entsprechend verschlossen werden, sodass ein Schutz der Einrichtung vor Umwelteinflüssen realisiert werden kann.In a particular embodiment, a housing is provided for the device, which is designed to be closable by means of a housing cover. With the housing cover open, the device can be introduced into the housing and also serviced there. The housing can be closed appropriately by the housing cover, so that the device can be protected from environmental influences.

Zum erfindungsgemäßen Funktionsprinzip der Einrichtung wird angeführt, dass die Schlagmasse als Ausgangsposition ihre Ruheposition einnimmt. Bevorzugt wird vorgeschlagen, dass ein Impulsverstärker vorgesehen wird, um die Schlagmasse in ihrer Ruheposition zu halten. Dadurch wird ausgeschlossen, dass eine Bewegung der Schlagmasse stattfindet, die ungewollt ist.With regard to the functional principle of the device according to the invention, it is stated that the impact mass assumes its rest position as a starting position. It is preferably proposed that a pulse amplifier be provided in order to keep the impact mass in its rest position. This prevents the impact mass from moving that is unintentional.

Dazu ist der Impulsverstärker als Magnet ausgeführt, insbesondere als Neodym-Magnet. Dieser kann in die Schlagmasse integriert sein oder einstückig mit dieser ausgeführt sein. Die Schlagmasse besteht in dieser Ausführungsform aus der Masse, einem den Körper der Masse in Längsrichtung verlängernden Führung, in welcher die Sicherung geführt wird und dem Impulsverstärker.For this purpose, the pulse amplifier is designed as a magnet, in particular as a neodymium magnet. This can be integrated into the impact mass or made in one piece with it. In this embodiment, the impact mass consists of the mass, a guide which extends the body of the mass in the longitudinal direction and in which the fuse is guided, and the pulse amplifier.

Damit der Impulsverstärker die Schlagmasse in der Ruheposition halten kann, sollte der Gehäusedeckel magnetisierbar gestaltet sein, bspw. aus Metall. Dann kann der Impulsverstärker durch seine Magnetkraft die Schlagmasse in der Ruheposition halten, in dem die Magnetkraft des Impulsverstärkers auf den Gehäusedeckel wirkt.So that the pulse amplifier can hold the impact mass in the rest position, the housing cover should be designed to be magnetizable, for example made of metal. The pulse amplifier can then use its magnetic force to hold the impact mass in the rest position, in which the magnetic force of the pulse amplifier acts on the housing cover.

Durch eine insbesondere fernbedienbare Auslösung eines Elektromagneten kann die Schlagmasse nun aus ihrer Ruheposition hinausbewegt werden, und zwar in Richtung ihrer Aktivierungsposition. Dazu ist die Schlagmasse mit dem Anker des Elektromagneten verbunden. Durch die Magnetkraft des Elektromagneten wird dann der Anker mit der Schlagmasse in Bewegung versetzt und aus seiner Ruheposition herausbewegt. Dazu muss eine Magnetkraft aufgewendet werden, die größer ist, als die Haltekraft des Impulsverstärkers. Aufgrund der benötigten Kraft des Magneten zur Überwindung der Haltekraft des Impulsverstärkers, wirkt ein größerer Bewegungsimpuls auf die Schlagmasse als ohne Vorhandensein des Impulsverstärkers. Dadurch wird eine sicherere Zündung der Zündvorrichtung erreicht, da mit einer größeren Kraft die Wirkverbindung von Schlagstück und Zündvorrichtung erreicht wird.The striking mass can now be moved out of its rest position, specifically in the direction of its activation position, by triggering an electromagnet, which can in particular be remotely controlled. For this purpose, the impact mass is connected to the armature of the electromagnet. The armature with the striking mass is then set in motion by the magnetic force of the electromagnet and moved out of its rest position. For this purpose, a magnetic force must be applied that is greater than the holding force of the pulse amplifier. Due to the required force of the magnet to overcome the holding force of the pulse amplifier, a larger movement impulse acts on the impact mass than without the presence of the pulse amplifier. As a result, a more reliable ignition of the ignition device is achieved, since the operative connection of the hammer and the ignition device is achieved with a greater force.

Bei der Bewegung der Schlagmasse aus ihrer Ruheposition hinaus bewegt die Schlagmasse damit den Umlenkhebel und sorgt dafür, dass das Schlagstück in Richtung Zündvorrichtung bewegt wird und zwar in einer Geschwindigkeit und mit einem so hohen Impuls, dass das Schlagstück die Zündvorrichtung aktiviert, sodass die Zündvorrichtung die Munition anzünden kann.When the striking mass moves out of its rest position, the striking mass moves the lever and ensures that the striking piece is moved in the direction of the ignition device at a speed and with such a high impulse that the striking piece activates the ignition device so that the ignition device the Can ignite ammunition.

Die Kraftübertragung von Schlagmasse auf den Umlenkhebel kann dabei durch Aufnahme des Umlenkhebels in die Führung der Schlagmasse geschehen, aber auch durch aufeinander Einwirkende Vorsprünge und/oder Kanten der Schlagmasse.The power transmission from the impact mass to the reversing lever can take place by receiving the reversing lever in the guide of the impact mass, but also through mutually acting projections and / or edges of the impact mass.

Nach der Bewegung der Schlagmasse und dem anschließenden Anzünden der Munition kann die Schlagmasse wieder durch Abschalten des Elektromagneten in seine Ruheposition zurückbewegt werden. Die Vorrichtung befindet sich dann wieder in der Ruheposition bzw. in der Ausgangsposition.After moving the striking mass and then igniting the ammunition, the striking mass can be moved back into its rest position by switching off the electromagnet. The device is then again in the rest position or in the starting position.

Zur Zurückführung der Schlagmasse in ihre Ruheposition wird bevorzugt vorgeschlagen, dass die Vorrichtung ein Rückholelement beinhaltet, welches bei nicht eingeschaltetem Elektromagneten das Führungselement in seiner Ruheposition bewegen kann. Als einfachste Ausführungsform kann hierzu eine Feder vorgesehen sein, aber auch hydraulische, elektrische oder pneumatische Rückholelemente sind denkbar.To return the striking mass to its rest position, it is preferably proposed that the device contain a return element which can move the guide element in its rest position when the electromagnet is not switched on. As the simplest embodiment, a spring can be provided for this purpose, but hydraulic, electrical or pneumatic return elements are also conceivable.

Bei der Verwendung eines Rückholelements muss der Elektromagnet so ausgelegt sein, sodass die Antriebskraft, die Kraft des Rückholelements und gegebenenfalls die Haltekraft des Impulsverstärkers überwinden kann, um das Führungselement von seiner Ruheposition in die Aktivierungsposition zu überführen.When using a return element, the electromagnet must be designed in such a way that the driving force, the force of the return element and possibly the holding force of the pulse amplifier can be overcome in order to transfer the guide element from its rest position to the activation position.

Durch die Kraft des Impulsverstärkers bzw. des Rückholelements wird sichergestellt, dass das Führungselement in seiner Ruheposition gehalten wird. Dadurch wird das Risiko einer unabsichtlichen Anzündung herabgesetzt. Zur weiteren Sicherung gegen unabsichtliches Anzünden der Munition wird erfindungsgemäß vorgeschlagen, eine vorgenannte Sicherung zu verwenden, welche die Bewegung des Umlenkhebels behindern kann.The force of the pulse amplifier or the return element ensures that the guide element is held in its rest position. This will reduce the risk of accidental ignition. To further protect against unintentional ignition of the ammunition, it is proposed according to the invention to use an aforementioned fuse which can hinder the movement of the reversing lever.

Die Sicherung kann dazu ebenfalls fernbedienbar gestaltet sein und kann entweder aktiviert werden, sodass eine Bewegung des Umlenkhebels zur Herstellung der Wirkverbindung zwischen Schlagstück und Zündvorrichtung möglich ist oder verhindert wird. In letzterem Falle sichert die Sicherung den Umlenkhebel, sodass dieser keine Wirkverbindung zwischen Schlagstück und Zündvorrichtung herbeiführen kann. Dadurch, dass der Umlenkhebel durch die Sicherung behindert wird, wird sichergestellt, dass das Schlagstück das Anzündelement nicht aktivieren kann. Durch die Kombination der Maßnahme des Haltens des Führungselements in der Ruheposition, ggf. über einen Impulsverstärker, und der Sicherung ist eine sehr hohe Sicherheit gegen unabsichtliches Anzünden der Munition gewährleistet.For this purpose, the safety device can also be designed so that it can be operated remotely and can either be activated so that a movement of the reversing lever to establish the operative connection between the hammer and the ignition device is possible or prevented. In the latter case, the safety device secures the reversing lever so that it cannot establish an operative connection between the striker and the ignition device. The fact that the reversing lever is hindered by the fuse ensures that the hammer cannot activate the ignition element. The combination of the measure of holding the guide element in the rest position, possibly via a pulse amplifier, and the fuse ensures a very high level of security against unintentional ignition of the ammunition.

In einer besonderen Ausführungsform wird vorgeschlagen, einen insbesondere fernbedienbaren Sicherungsantrieb zu verwenden, welcher die Sicherung aktivieren oder deaktivieren kann. Bevorzugt wird der Sicherungsantrieb als Schwenkmagnet ausgeführt, welcher die Sicherung als Welle drehen oder schwenken kann.In a particular embodiment, it is proposed to use a safety drive that can in particular be remotely controlled and that can activate or deactivate the safety device. The safety drive is preferably designed as a swivel magnet which can rotate or swivel the safety device as a shaft.

Der Umlenkhebel kann durch ein Lager gelagert sein. Durch ein solches Lager kann eine Drehbewegung des Umlenkhebels realisiert werden. Weiterhin kann ein Anschlag vorgesehen sein, um die Bewegung des Umlenkhebels zu begrenzen.The reversing lever can be supported by a bearing. A rotary movement of the reversing lever can be implemented by means of such a bearing. Furthermore, a stop can be provided in order to limit the movement of the reversing lever.

In den Figuren 1 und 2 ist eine Ausführungsform der erfindungsgemäßen Einrichtung gezeigt. Darin offenbart ist eine in einem Gehäuse 1 geführte Schlagmasse 4, welche einerseits mit dem Anker 2 eines Elektromagneten 3 verbunden ist und andererseits mit einem Impulsverstärker 6, welcher hier als Magnet ausgeführt ist. Der Impulsverstärker 6 ist dabei mittels einer Führung mit der Schlagmasse 4 verbunden. Der Impulsverstärker kann hierbei mit einem Gehäusedeckel 11 zusammenwirken und auf diesen eine Magnetkraft ausüben. Mittels dem Gehäusedeckel 11 kann das Gehäuse 1 verschlossen werden.In the Figures 1 and 2 an embodiment of the device according to the invention is shown. Disclosed therein is an impact mass 4 guided in a housing 1, which is connected on the one hand to the armature 2 of an electromagnet 3 and on the other hand to a pulse amplifier 6, which is designed here as a magnet. The pulse amplifier 6 is connected to the impact mass 4 by means of a guide. The pulse amplifier can interact with a housing cover 11 and exert a magnetic force on it. The housing 1 can be closed by means of the housing cover 11.

Zwischen Schlagmasse 4 und Gehäuse 1 ist ein Rückholelement 5 angeordnet, welches die Schlagmasse 4 bei ausgeschaltetem Elektromagneten 3 in Richtung des Gehäusedeckels 11 in seine Ruheposition bewegt. Dazu ist die Schlagmasse 4 längsbeweglich im Gehäuse 1 gelagert.A return element 5 is arranged between the striking mass 4 and the housing 1 and moves the striking mass 4 in the direction of the housing cover 11 into its rest position when the electromagnet 3 is switched off. For this purpose, the impact mass 4 is mounted in the housing 1 such that it can move longitudinally.

Der Impulsverstärker 6 kann die Schlagmasse 4 mit einer definierten Kraft in der Ruheposition halten, welche in Richtung des Gehäusedeckels 11 angeordnet ist.The pulse amplifier 6 can hold the impact mass 4 with a defined force in the rest position, which is arranged in the direction of the housing cover 11.

Des Weiteren befindet sich im Gehäuse 1 eine Zündvorrichtung 8 und ein Umlenkhebel 7. Die Aufnahme für die Zündvorrichtung 8 ist rechtwinklig zur Bewegungsrichtung der Schlagmasse 4 in das Gehäuse 1 eingebracht und so positioniert, dass die vom Elektromagneten 3 aufgebrachte Kraft auf das von dem Impulsverstärker 6 gehaltene Führungselement 4 wirken kann.Furthermore, an ignition device 8 and a deflection lever 7 are located in the housing 1. The receptacle for the ignition device 8 is inserted into the housing 1 at right angles to the direction of movement of the impact mass 4 and positioned so that the force applied by the electromagnet 3 is applied to that of the pulse amplifier 6 held guide element 4 can act.

Sobald die Kraft des Elektromagneten 3 die Haltekraft des Impulsverstärkers 6 übersteigt, wird die Schlagmasse 4 von dem Gehäusedeckel 11 getrennt und in Bewegung versetzt. Beim Zurücklegen eines definierten Weges wirkt die Schlagmasse 4 auf den Umlenkhebel 7, welcher die Bewegungsenergie auf die Zündvorrichtung 8 überträgt und die Zündvorrichtung 8 zündet. Dabei wirkt eine um die Haltekraft des Impulsverstärkers 6 verstärkte Impulskraft auf die Zündvorrichtung 8. Zur Zündung der Zündvorrichtung 8 ist am Umlenkhebel 7 ein Schlagstück 12 angeordnet.As soon as the force of the electromagnet 3 exceeds the holding force of the pulse amplifier 6, the impact mass 4 is separated from the housing cover 11 and set in motion. When traveling a defined distance, the impact mass 4 acts on the reversing lever 7, which transfers the kinetic energy to the ignition device 8 and ignites the ignition device 8. In this case, an impulse force increased by the holding force of the impulse amplifier 6 acts on the ignition device 8. To ignite the ignition device 8, a hammer 12 is arranged on the reversing lever 7.

Um eine ungewollte Übertragung der Energie auf die Zündvorrichtung 8 zu verhindern, wird in das Gehäuse 1 eine Sicherung 9 integriert, welche durch einen Sicherungsantrieb 10 angetrieben werden kann und eine definierte Winkeländerung ausführen kann. Dazu ist die Sicherung 9 als Welle ausgeführt und kann mittels dem Sicherungsantrieb 10 in eine Schwenk- bzw. Drehbewegung versetzt werden. Die Sicherung 9 ist zum Umlenkhebel 7 so angeordnet, dass durch eine in die Sicherung eingebrachte Ausnehmung die mögliche Winkelbewegung des Umlenkhebels 7 durch das Schwenken der Sicherung 9 eingeschränkt oder freigegeben werden kann. Mit dieser Einschränkung wird auch die Wirkung der Zündvorrichtung 8 verhindert, sodass ein Auftreffen auf das Anzündelement 8 vom Schlagstück 12 nicht mehr möglich ist. Die Ansteuerungsfolge Sicherungsantrieb 10, Elektromagnet 3 sorgt bei gewollter Schussabgabe für das Entsichern der Munition mit anschließendem Spannen und Aktivierung der Zündvorrichtung 8. Eine ungewollte Schussabgabe durch Vibration oder Schock ist daher nicht möglich, da sich das System bei abgeschaltetem Elektromagnet 3 durch die Sicherung 9 und des integrierten Rückholelements 5 sowie des Impulsverstärkers 6 immer in einem sicheren Zustand bzw. in seiner Ruheposition befindet und bei Ausfall des Elektromagneten 3 in diesen automatisch zurückkehrt.In order to prevent unwanted transmission of the energy to the ignition device 8, a fuse 9 is integrated into the housing 1, which can be driven by a fuse drive 10 and can perform a defined change in angle. For this purpose, the safety device 9 is designed as a shaft and can be set in a pivoting or rotating movement by means of the safety drive 10. The safety device 9 is arranged in relation to the reversing lever 7 in such a way that the possible angular movement of the reversing lever 7 can be restricted or released by pivoting the safety device 9 through a recess made in the safety device. With this restriction, the effect of the ignition device 8 is also prevented, so that striking the ignition element 8 from the hammer 12 is no longer possible. The activation sequence safety drive 10, electromagnet 3 ensures the release of the ammunition with subsequent cocking and activation of the ignition device 8 when the shot is intended. An unintentional discharge of shots by vibration or shock is therefore not possible, since the system with the electromagnet 3 switched off by the fuse 9 and of the integrated return element 5 and the pulse amplifier 6 is always in a safe state or in its rest position and automatically returns to it if the electromagnet 3 fails.

Der Umlenkhebel ist durch ein Lager 13 drehbeweglich gelagert, so dass eine Drehbewegung des Umlenkhebels 13 zur Zündung der Zündvorrichtung 8 führen kann. Diese Drehbewegung kann durch einen Anschlag 14 begrenzt werden, um unnötige Bewegungen des Umlenkhebels 7 zu vermeiden.The reversing lever is rotatably supported by a bearing 13, so that a rotating movement of the reversing lever 13 can lead to the ignition of the ignition device 8. This rotary movement can be limited by a stop 14 in order to avoid unnecessary movements of the reversing lever 7.
