In order to safely avoid unintentional ignition of the tilt lever igniter (1) before its intended use, the invention proposes that the striker pin spring (3) is in its untensioned state in the unused rocker arm igniter (1), and by a separate tensioning lever (7) is tensioned as soon as the rocker arm igniter (1) is intended to be used.
Description
Die Erfindung betrifft einen Kipphebelzünder mit einem Zünderkopf, der einen von einer Schlagbolzenfeder beaufschlagten, schwenkbar angeordneten Schlagbolzen umfasst, und mit einem Sicherungsbügel, der im selben Drehsinn wie der Schlagbolzen von einer Ausgangsposition, bei der er in Richtung auf den Zünderkopf gedrückt ist, in eine Schlagbolzen-Freigabeposition schwenkbar angeordnet ist.The invention relates to a Kipphebelzünder with a detonator head, which comprises a acted upon by a firing pin spring, pivotally mounted firing pin, and with a securing bracket, in the same direction as the firing pin from a starting position in which it is pressed in the direction of the detonator head in a Firing pin release position is pivotally mounted.
Derartige Kipphebelzünder sind beispielsweise aus der
Weitere Kipphebel beschreiben die
Nachteilig ist bei den bekannten Kipphebelzündern unter anderem, dass die Schlagbolzenfeder auch dann vorgespannt ist, wenn der Kipphebelzünder nicht bestimmungsgemäß verwendet wird, wenn also die den Kipphebelzünder verwendende Handgranate nicht im Gebrauch ist. Denn dadurch wird ein ungewolltes Auslösen des Zünders (etwa durch ein unbeabsichtigtes Ziehen des Sicherheitssplintes) wesentlich begünstigt.A disadvantage of the known Kipphebelzündern, inter alia, that the firing pin spring is also biased when the Kipphebelzünder is not used as intended, so if the Tipper lever using hand grenade is not in use. Because of this, an unwanted triggering of the detonator (such as by accidentally pulling the safety pin) is much favored.
Der Erfindung liegt die Aufgabe zugrunde, einen Kipphebelzünder anzugeben, bei dem ein unbeabsichtigtes Zünden vor seinem bestimmungsgemäßen Einsatz sicher vermieden wird.The invention has for its object to provide a Kipphebelzünder, in which accidental ignition is reliably avoided before its intended use.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.
Die Erfindung beruht im Wesentlichen auf dem Gedanken, dass sich bei einem nicht im Gebrauch befindlichen Kipphebelzünder die Schlagbolzenfeder in ihrem ungespannten Zustand befinden sollte und durch einen separaten Spannhebel spannbar ist, sobald der den Kipphebelzünder enthaltende Wurfkörper bestimmungsgemäß eingesetzt wird (Unstored Energy Fuze Head).The invention is based essentially on the idea that in a not in use Kipphebelzünder the firing pin spring should be in its untensioned state and can be tensioned by a separate clamping lever as soon as the Kipphebelzünder containing projectile is used as intended (Unstored Energy Fuze Head).
Hierzu ist an dem Zünderkopf des Kipphebelzünders der von einer Ruhe- in eine Scharfstellung betätigbare Spannhebel über eine Spannhebelwelle mit der Schlagbolzenfeder verbunden, derart, dass nur bei in seiner Ausgangsposition befindlichem Sicherungsbügel die Schlagbolzenfeder von ihrem ungespannten Zustand in ihren gespannten Zustand betätigbar und die Schlagbolzenfeder in ihrem gespannten Zustand mittels einer Sicherungseinrichtung arretierbar ist.For this purpose, at the igniter head of Kipphebelzünders of operable from a rest in a focus clamping lever is connected via a tension lever shaft with the firing pin spring, such that only in befindlichem in its initial position securing bracket the firing pin spring actuated from its untensioned state in its tensioned state and the firing pin spring in their tensioned state by means of a security device can be locked.
Da sich die Schlagbolzenfeder bei dem nicht im Gebrauch befindlichen Kipphebelzünder in ihrem entspannten Zustand befindet, kann vorteilhafterweise bei dem erfindungsgemäßen Kipphebelzünder ein Sicherungssplint entfallen.Since the firing pin spring is in its relaxed state when not in use Kipphebelzünder, advantageously a Sicherungssplint can be omitted in the Kipphebelzünder invention.
Um sicherzustellen, dass die Schlagbolzenfeder nur spannbar ist, wenn sich der Sicherungsbügel in seiner Ausgangsposition befindet, hat es sich als zweckmäßig erwiesen, wenn der Sicherungsbügel einen Nocken trägt, der in eine Führungsnut des Spannhebels eingreift, derart, dass der Spannhebel nur dann in seine Scharfstellung betätigbar ist, wenn der Sicherungsbügel in seiner Ausgangsposition gehalten wird und dass die Führungsnut den Nocken in der Scharfstellung des Spannhebels freigibt, sodass der Sicherungsbügel in die Schlagbolzen-Freigabeposition schwenkbar ist.To ensure that the firing pin spring is tensioned only when the circlip is in its starting position, it has proved to be useful when the circlip carries a cam which engages in a guide groove of the clamping lever, such that the clamping lever only in his Focus can be actuated, when the safety latch is held in its initial position and that the guide groove releases the cam in the armed position of the clamping lever, so that the securing bracket is pivotable in the firing pin release position.
Bei der Schlagbolzenfeder kann es sich vorzugsweise um eine durch die Spannhebelwelle geführte Schenkelfeder handeln, deren erster Schenkel mit der Spannhebelwelle und deren zweiter Schenkel mit dem Schlagbolzen verbunden ist.The firing pin spring may preferably be a leg spring guided by the tension lever shaft, whose first leg is connected to the tension lever shaft and whose second leg is connected to the firing pin.
Die Sicherungseinrichtung zur Sicherung der Schlagbolzenfeder in ihrer gespannten Position umfasst vorzugsweise ein mit der Spannhebelwelle drehfest verbundenes, scheibenförmiges Riegelrad, welches auf seinem äußeren Umfang mindestens eine erste Rastnut enthält, und einen um eine Drehachse schwenkbar angeordneten Verriegelungsarm, wobei die Drehachse des Verriegelungsarmes parallel zu der Spannhebelwelle angeordnet ist und der Verriegelungsarm an seinem der Drehachse abgewandten Ende ein Rastelement aufweist, das durch eine vorgespannte Feder gegen den äußeren Umfang des Riegelrades gedrückt wird, sodass das Rastelement beim Erreichen der Scharfstellung des Spannhebels - und damit des gespannten Zustandes der Schlagbolzenfeder - in die zweite Rastnut des Riegelrades eingreift.The securing device for securing the firing pin spring in its cocked position preferably comprises a disk-shaped locking wheel which is connected in a rotationally fixed manner to the tensioning lever shaft and which contains at least one first latching groove on its outer circumference, and a locking arm which is pivotable about an axis of rotation, wherein the axis of rotation of the locking arm is parallel to the latching arm Tension lever shaft is arranged and the locking arm has at its end remote from the axis of rotation a locking element which is pressed by a prestressed spring against the outer periphery of the locking wheel, so that the locking element upon reaching the focus of the clamping lever - and thus the tensioned state of the firing pin spring - in the second locking groove of the locking wheel engages.
Vorteilhafterweise ist an dem äußeren Umfang des Riegelrades eine erste Rastnut angeordnet, derart, dass in der Ruhestellung des Spannhebels das Rastelement des Verriegelungsarmes in die erste Rastnut des Riegelrades eingreift und dadurch der Spannhebel in der Ruhestellung gesichert wird.Advantageously, a first detent groove is arranged on the outer circumference of the locking wheel, such that in the rest position of the tensioning lever, the detent element of the locking arm engages in the first detent groove of the locking wheel and thereby the tension lever is secured in the rest position.
Um die gespannte Schlagbolzenfeder auf einfache Weise wieder zu entspannen, wenn ein Einsatz des entsprechenden Wurfkörpers nicht mehr beabsichtigt ist, hat es sich als vorteilhaft erwiesen, wenn die Sicherungseinrichtung durch ein von außen betätigbares Entspannelement entsicherbar ist, sodass bei in seiner Ausgangsposition befindlichem Sicherungsbügel bei Betätigung des Entspannelementes die Schlagbolzenfeder wieder von ihrem gespannten in ihren ungespannten Zustand gelangt.In order to relax the cocked firing pin spring in a simple manner again, when an insert of the corresponding projectile is no longer intended, it has proved to be advantageous if the securing device can be unlocked by an externally actuated release element, so that when operated in its initial position securing bracket of the relaxation element the striker spring returns from its tensioned to its untensioned state.
Bei dem Entspannelement kann es sich um ein Druck- oder Schiebeelement handeln, welches bei seiner Betätigung auf das der Drehachse abgewandte Ende des Verriegelungsarmes wirkt, derart, dass das Rastelement des Verriegelungsarmes aus der Rastnut des Riegelrades gelangt und der Spannhebel durch den Druck der Schlagbolzenfeder von seiner Scharfstellung in seine Ruhestellung zurückgeschwenkt wird.In the relaxation element may be a pressure or sliding element, which acts in its operation on the end remote from the axis of rotation of the locking arm, such that the locking element of the locking arm of the locking groove reaches the locking wheel and the clamping lever is pivoted back by the pressure of the firing pin spring from its focus to its rest position.
Um das Entspannelement mit der Wurfhand, die den Sicherungsbügel in ihrer Ausgangsposition hält, entspannen zu können, hat es sich als vorteilhaft erwiesen, das Entspannelement durch eine Ausnehmung des Sicherungsbügels von außen betätigbar anzuordnen.In order to be able to relax the release element with the throwing hand, which holds the securing clip in its initial position, it has proven to be advantageous to be able to actuate the release element from outside by means of a recess of the securing clip.
Um also ein unbeabsichtigtes Zünden des Kipphebelzünders vor seiner bestimmungsgemäßen Verwendung sicher zu vermeiden, ist vorgesehen, dass sich bei dem nicht im Gebrauch befindlichen Kipphebelzünder die Schlagbolzenfeder in ihrem ungespannten Zustand befindet, und durch einen separaten Spannhebel spannbar ist, sobald der Kipphebelzünder bestimmungsgemäß eingesetzt werden soll.Thus, to avoid accidentally igniting the Kipphebelzünders before its intended use safely, it is provided that in the not in use Kipphebelzünder the firing pin spring is in its untensioned state, and can be tensioned by a separate clamping lever as soon as the Kipphebelzünder is intended to be used ,

Allerdings ist es zum Spannen der Schlagbolzenfeder 3 zwingend erforderlich, dass der Sicherungsbügel 5 gedrückt bleibt. Anderenfalls würde bei der Betätigung des Spannhebels 7 von seiner Ruhe- in seine Scharfstellung über die Schlagbolzenfeder 3 der Schlagbolzen 4 und damit auch der Sicherungsbügel 5 in Richtung auf einen Vorsprung 14 verschwenkt und arretiert werden, und die Schlagbolzenfeder 3 würde nicht auf die für den Zündvorgang erforderliche Vorspannung spannbar sein.However, it is absolutely necessary for tensioning the
Sobald der Spannhebel 7 bei gedrücktem Sicherungsbügel 5 in seine Scharfstellung geschwenkt ist, wird die Schlagbolzenfeder 3 in dieser Position mittels einer Sicherungseinrichtung 11 gesichert, sodass bei Loslassen des Spannhebels 7 die Schlagbolzenfeder 3 nicht automatisch durch Zurückdrehen der Spannhebelwelle 8 wieder in ihren entspannten Zustand gelangt.Once the clamping
Um außerdem sicherzustellen, dass ein Vorschnellen des Schlagbolzens 4 erst möglich ist, wenn die Schlagbolzenfeder 3 eine für den Zündvorgang ausreichend hohe Spannung besitzt, der Spannhebel 7 sich also bereits in der Scharfstellung befindet, trägt der Sicherungsbügel 5 einen Nocken 12 (
Nach Überwinden des Vorsprunges 14 durch Drücken des Sicherungsbügels 5 lässt sich der Spannhebel 7 weiter schwenken und rastet bei (erneut) zu geringem Druck des Sicherungsbügels 5 und den zweiten Vorsprung 25 in seine Scharfstellung ein und gibt nach Erreichen der Scharfstellung durch eine entsprechende randseitige Ausnehmung 15 den Nocken 12 des Sicherungsbügels 5 frei, sodass der Sicherungsbügel 5 in die Schlagbolzen-Freigabeposition schwenkbar ist (sobald die Hand des Verwenders der Handgranate den Sicherungsbügel loslässt).After overcoming the
Die Sicherungseinrichtung 11 umfasst ein mit der Spannhebelwelle 8 drehfest verbundenes, scheibenförmiges Riegelrad 16, welches auf seinem äußeren Umfang eine zweite Rastnut 17 enthält, und einen um eine Drehachse 18 schwenkbar angeordneten Verriegelungsarm 19. Dabei ist die Drehachse 18 des Verriegelungsarmes 19 parallel zu der Spannhebelwelle 8 angeordnet, und der Verriegelungsarm 19 weist an seinem der Drehachse 18 abgewandten Ende ein Rastelement 20 auf. Dieses Rastelement 20 wird durch eine vorgespannte Feder 21 gegen den äußeren Umfang des Riegelrades 16 gedrückt, sodass das Rastelement 20 beim Erreichen der Scharfstellung des Spannhebels 7 - und damit des gespannten Zustandes der Schlagbolzenfeder 3 - in die zweite Rastnut 17 desThe securing device 11 comprises a disc-shaped

Die Erfindung ist selbstverständlich nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. So kann statt einer Schenkelfeder beispielsweise auch eine Blattfeder als Schlagbolzenfeder verwendet werden, die durch einen entsprechenden auf der Spannhebelwelle angeordneten Nocken gespannt wird.Of course, the invention is not limited to the embodiment described above. So instead of a leg spring, for example, a leaf spring can be used as a firing pin spring, which is tensioned by a corresponding arranged on the clamping lever shaft cam.
Als Entspannelement kann beispielsweise statt eines Schiebers auch ein Druckelement verwendet werden, welches den Verriegelungsarm aus der Rastnut des Riegelarmes herausdrückt.As a relaxation element, for example, instead of a slider and a pressure element can be used, which pushes the locking arm out of the locking groove of the locking arm.
