Description

Die Erfindung betrifft einen Geschoßzünder mit einer Sicherungsein­richtung aus einem ersten Zündmittel in einem Gehäuse, an dem ein Ro­tor mit einem zweiten Zündmittel drehbar gelagert ist, welcher über das erste Zündmittel zur Bildung einer Zündkette schwenkbar ist, und miteiner in die Zündkette wahlweise hineinbewegbaren Verzögerungs­ladung.The invention relates to a projectile fuse with a safety device comprising a first ignition means in a housing on which a rotor is rotatably mounted with a second ignition means which can be pivoted via the first ignition means to form an ignition chain, and with a delay charge which can be moved into the ignition chain.

Eine derartige Sicherungseinrichtung ist in der DE 26 40 782 C3 und in der DE 31 07 110 A1 beschrieben. Weist das Zündmittel eine Zünverzögerung auf, dann arbeitet die Zündkette in jedem Fall mit der Zündverzögerung. Es ist jedenfalls nicht möglich, je nach dem Einsatzfall mit oder ohne Zündverzögerung zu arbeiten.Such a safety device is described in DE 26 40 782 C3 and in DE 31 07 110 A1. If the ignition device has an ignition delay, the ignition chain always works with the ignition delay. In any case, depending on the application, it is not possible to work with or without ignition delay.

Zwei voneinander unabhängige Zündketten vorzusehen, von denen die eine mit Zündverzögerung und die andere ohne Zündverzögerung arbeitet, wäre aufwendig und würde zusätzliche Probleme im Hinblick auf die Detonatorsicherheit bringen. Durch die DE-AS 10 65 758 ist ein Ge­schoßzünder offenbart, bei dem zwischen einer Zündpille und dem Detonator am Rotor ein Freiraum besteht, der von der Zündpille über­brückbar ist. Eine Verzögerungspille ist über einen Schieber in den Freiraum einschiebbar, wenn eine Zündverzögerung gewünscht wird. Der Aufbau dieses Geschoßzünders erscheint technisch aufwenidg und kompliziert. In der Unterseite des Rotors befindet sich eine Nut, in welcher die Zündpille, die Verzögerungspille und die Übertragungs­pille übereinander liegend durch getrennte Schieber unter Federkraft verschiebbar sind.Providing two ignition chains that are independent of one another, one of which operates with a delayed ignition and the other without a delayed ignition, would be complex and would cause additional problems in terms of detonator safety. DE-AS 10 65 758 discloses a projectile detonator in which there is a free space between a squib and the detonator on the rotor which can be bridged by the squib. A delay pill can be inserted into the free space via a slide if an ignition delay is desired. The structure of this projectile detonator appears technically complex and complicated. In the underside of the rotor there is a groove in which the squib, the retardation pill and the transmission pill can be moved one above the other by means of separate slides under spring force.

Aufgabe der Erfindung ist es, einen Geschoßzünder mit einer Sicherungs­einrichtung der eingangs genannten Art vorzuschlagen, bei dem die gleiche Zündkette wahlweise entweder mit einer Zündverzögerung oder ohne Zündverzögerung betrieben werden kann und bei dem die Zündkette raumsparend durch einfache Bauteile aufgebaut ist, die eine sichere Funktion gewährleisten.The object of the invention is to propose a projectile detonator with a safety device of the type mentioned in the introduction, in which the same ignition chain can be operated either with an ignition delay or without ignition delay and in which the ignition chain is constructed in a space-saving manner by simple components which ensure reliable operation .

Erfindungsgemäß ist obige Aufgabe bei einer Sicherungseinrichtung der eingangs genannten Art durch die Merkmale des Patentanspruches 1 gelöst.According to the invention, the above object is achieved in a safety device of the type mentioned at the outset by the features of patent claim 1.

Dieser neue Geschoßzünder besitzt Zündmittel, die einfach im Aufbau sind und einzelne, ohne großen technischen Aufwand einsetzbare und austauschbare Eintelteile besitzen. Diese Einzelteile sind leicht herstellbar und montierbar, wodurch insgesamt die Wirtschaftlich­keit in der Lagerhaltung und Produktion erhöht wird. Ist eine Zündung ohne Zündverzögerung vorgesehen, dann ist der Schieber so bewegt, daß in der Scharfstellung des Rotors die Verzögerungsladung außerhalb der Zündkette steht. Ist dagegen eine Zündung mit Zündverzögerung vorgesehen, dann ist der Schieber so bewegt, daß die Verzögerungs­ladung in der Zündkette steht.This new projectile detonator has ignition means that are simple in construction and have individual, interchangeable parts that can be used and replaced without great technical effort. These individual parts are easy to manufacture and assemble, which increases the overall economy in warehousing and production. If ignition without ignition delay is provided, then the slide is moved so that the delay charge is outside the ignition chain when the rotor is in focus. If, on the other hand, an ignition with ignition delay is provided, the slide is moved so that the delay charge is in the ignition chain.

Vorzugsweise steht in der Sicherstellung des Rotors die Verzögerungs­ladung weder in dem Freiraum noch über dem Zündmittel.When the rotor is secured, the delay charge is preferably neither in the free space nor above the ignition means.

Aus baulichen Gründen ist der Schieber vorzugsweise am Gehäuse gela­gert. Er könnte jedoch auch am Rotor selbst gelagert sein.For structural reasons, the slide is preferably mounted on the housing. However, it could also be mounted on the rotor itself.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus der folgenden Beschreibung eines Ausführungsbeispiels und den Unteransprüchen. In der Zeichnung zeigen:

  • Figur 1 eine Sicherungseinrichtung in Sicherstellung,
  • Figur 2 die Sicherungseinrichtung in Scharfstellung ohne Zündver­zögerung,

  • Figur 4 die Sicherungseinrichtung in Scharfstellung mit Zündver­zögerung und
  • Figur 5 einen Teilschnitt längs der Linie V-V nach Figur 4.

  • FIG. 1 shows a security device in security,
  • FIG. 2 shows the safety device in the armed position without ignition delay,
  • FIG. 3 shows a partial section along the line III-III according to FIG. 2,

In einem Gehäuse (1) ist ein Zündmittel (2), hier ein Zündübertrager, angeordnet. An dem Gehäuse (1) ist an einer Achse (3) ein segmentför­miger Rotor (4) schwenkbar gelagert, der durch eine quer zur Dreh­achse (3) eingebrachte Ausnehmung (8) U-förmig gestaltet ist. In einem ersten, in Figur 3 obenliegenden Schenkel (4.1) trägt der Rotor (4) in einer zur Drehachse (3) parallelen Bohrung (5.1) ein Anzündstück (5). In dem zweiten und in Figur 3 untenliegenden Schen­kel (4.2) ist in einer wiederum parallel zur Rotordrehachse (3) parallelen zweiten Bohrung (6.1) ein Detonator (6) eingesetzt. Die Drehachse (3) des Rotors (4) ist in dem verbleibenden Steg (4.3) der U-Bauform vorgesehen. Zwischen dem Detonator (6) und dem Anzünd­stück (5) besteht somit ein Freiraum (7), der von der Ausnehmung (8) gebildet ist.An ignition device (2), here an ignition transmitter, is arranged in a housing (1). A segment-shaped rotor (4) is pivotally mounted on the housing (1) on an axis (3) and is U-shaped by a recess (8) made transversely to the axis of rotation (3). The rotor (4) carries an igniter (5) in a bore (5.1) parallel to the axis of rotation (3) in a first leg (4.1) located at the top in FIG. A detonator (6) is inserted in the second leg (4.2) located at the bottom in FIG. 3 in a second bore (6.1), which is again parallel to the rotor axis of rotation (3). The axis of rotation (3) of the rotor (4) is provided in the remaining web (4.3) of the U design. There is a free space (7) between the detonator (6) and the igniter (5), which is formed by the recess (8).

Am Gehäuse (1) ist an einer weiteren Achse (9) ein Träger (10) schwenkbar gelagert. Am einen, in die Ausnehmung (9) ragenden Ende des Trägers (10) ist eine Verzögerungsladung (11) angeordnet, die von einem Verzögerungsstück gebildet ist. Der Träger (10) ist mittels einer Feder (12) belastet. Er ist durch einen Sperrstift (13) in Sicherstellung des Rotors (4) und in Scharfstellung des Rotors (4), wenn ohne Zündverzögerung gearbeitet werden soll, arretiert (vgl. Figur 1, 2).A carrier (10) is pivotably mounted on the housing (1) on a further axis (9). A delay charge (11), which is formed by a delay piece, is arranged at one end of the carrier (10) projecting into the recess (9). The carrier (10) is loaded by means of a spring (12). It is locked by a locking pin (13) in the rotor (4) and in the arming of the rotor (4), if you want to work without ignition delay, locked (see Figure 1, 2).

In Sicherstellung ist der Rotor (4) durch ein Vorsicherungselement (14), das in eine Einbuchtung (15) des Umfangs des Rotors (4) greift, und durch ein Räder-Hemmwerk (16) mit einer abgeplatteten Scheibe (17) blockiert, die in eine zweite Einbuchtung (18) des Umfangs des Rotors (4) greift.In safety, the rotor (4) is blocked by a pre-securing element (14) which engages in an indentation (15) in the circumference of the rotor (4) and by a wheel locking mechanism (16) with a flattened disc (17) engages in a second indentation (18) of the circumference of the rotor (4).

Nach dem Lösen des Vorsicherungselements (14) aus der Einbuchtung (15) und dem Ablauf des Räder-Hemmwerks (16) gibt die abgeplattete Scheibe (17) den Rotor (4) auch an seiner zweiten Einbuchtung (18) frei. Er wird dann unter der Wirkung einer Feder (19) in die Scharf­stellung (vgl. Figuren 2 bis 5) gebracht.After the pre-securing element (14) has been released from the indentation (15) and the wheel inhibitor (16) has run off, the flattened disc (17) also releases the rotor (4) at its second indentation (18). It is then brought into focus (see FIGS. 2 to 5) under the action of a spring (19).

Ist ein Zünden ohne Zündverzögerung vorgesehen, dann bleibt der Träger (10) durch den Sperrstift (13) blockiert, so daß die Verzöge­rungsladung (11) außerhalb des Freiraums (7) steht (vgl. Figur 2, 3). Wird das Anzündstück (5) initiiert, dann zündet es über den Freiraum (7) hinweg den Detonator (6), der seinerseits das Zündmittel (2) zündet.If ignition without delay is provided, the carrier (10) remains blocked by the locking pin (13), so that the delay charge (11) is outside the free space (7) (cf. FIGS. 2, 3). If the igniter (5) is initiated, then it ignites the detonator (6) across the free space (7), which in turn ignites the ignition means (2).

Ist ein Zünden mit Zündverzögerung vorgesehen, dann wird der Sperr­stift (13) verschoben, so daß er den Träger (10) freigibt. Dieser verschwenkt dann unter der Kraft der Feder (12) so, daß die Verzöge­rungsladung (11) in dem Freiraum (7) steht (vgl. Figur 4, 5). Nach dem Initiieren des Anzündstücks (5) wird die Verzögerungsladung (11) angezündet. Dieses zündet nach ihrer Verzögerungszeit den Deto­nator (6), der dann seinerseits das Zündmittel (2) zündet.If ignition with delay is provided, the locking pin (13) is moved so that it releases the carrier (10). This then pivots under the force of the spring (12) so that the deceleration charge (11) is in the free space (7) (see FIGS. 4, 5). After initiating the igniter (5), the delay charge (11) is ignited. After its delay time, this ignites the detonator (6), which in turn ignites the ignition means (2).

Im Falle der gewünschten Zündverzögerung kann die Verzögerungsladung (11) in die Zündkette vor, während oder nach der Verschwenkung des Rotors (4) von der Sicherstellung in die Scharfstellung eingeschwenkt werden.In the event of the desired ignition delay, the delay charge (11) can be pivoted into the ignition chain before, during or after the pivoting of the rotor (4) from securing to the arming position.

Beim beschriebenen Ausführungsbeispiel steht die Verzögerungsladung (11) vor ihrem Verschwenken außerhalb des Freiraums (7) und nicht über dem Zündmittel (2). Bei einem anderen Ausführungsbeispiel kann die Verzögerungsladung (11) vor dem Verschwenken über dem Zündmittel (2) stehen. Der in Scharfstellung stehende Rotor (4) schwenkt dann das Anzündstück (5) und den Detonator (6) über bzw. unter die Verzöge­rungsladung (11). Ist in diesem Fall eine Zündung ohne Zündverzögerung gewünscht, dann wird der Träger (10) so bewegt, daß die Verzögerungs­einrichtung (11) aus der Zündkette geht. Dies kann vor, während oder nach dem Übergang des Rotors (4) von der Sicherstellung in die Scharfstellung erfolgen. Die Verzögerungsladung (11) befindet sich regelmäßig in einer durch die beiden Schenkel (4.1,4.2) des Rotors (4) geschützten Position.In the exemplary embodiment described, the delay charge (11) stands before it is pivoted outside the free space (7) and not above the ignition means (2). In another exemplary embodiment, the delay charge (11) can be positioned above the ignition means (2) before pivoting. The rotor (4) in focus then swings the igniter (5) and the detonator (6) above or below the delay charge (11). If an ignition without ignition delay is desired in this case, then the carrier (10) is moved so that the delay device (11) goes out of the ignition chain. This can be done before, during or after the transition of the rotor (4) from securing to arming. The delay charge (11) is regularly in a position protected by the two legs (4.1, 4.2) of the rotor (4).
