Abstract
Description
Die vorliegende Erfindung betrifft eine Auslösevorrichtung für durch Stolperdrähte oder andere für eine Fernauslösung bestimmte Drähte oder Schnüre auszulösende, insbesondere pyrotechnisch anzuzündende Signale, oder mechanische oder elektrische dem gleichen Zweck dienende Gerätschaften.The present invention relates to a triggering device for signals to be triggered by trip wires or other wires or cords intended for remote triggering, in particular pyrotechnically ignited signals, or mechanical or electrical devices serving the same purpose.
Aus der DE-PS 2 155 809 ist eine federausgelöste Auslösevorrichtung für derartige Signale oder Alarmanlagen bekannt, bei welcher eine auf einem Auslösehebel angeordnete Klammer mit den Auslösedrähten verbunden wird und nach Beeinflussung des Auslöse- oder Stolperdrahtes über den Auslösehebel einen Schlagbolzen auslöst, der wiederum ein Zündhütchen zündet und mit diesem ein pyrotechnisches Signal. Dabei ist der Schalthebel mit einem oberen Schaltnocken verbunden, der in gespanntem Zustand der Feder auf einen auf einem Schlagbolzen angeordneten unteren Schaltnocken einwirkt, wobei der obere Schaltnocken kugelschalenförmig in einer oberen Einziehung der einen Schlagbolzen aufnehmenden Hülse angeordnet ist und der Schlagbolzen durch allseitige Auslenkung des Auslösehebels betätigt werden kann.From DE-PS 2 155 809 a spring-triggered trigger device for such signals or alarm systems is known, in which a clamp arranged on a trigger lever is connected to the trigger wires and, after influencing the trigger or trip wire, triggers a firing pin via the trigger lever, which in turn triggers Primer ignites and with it a pyrotechnic signal. The switching lever is connected to an upper switching cam, which acts in the tensioned state of the spring on a lower switching cam arranged on a firing pin, the upper switching cam being arranged in the form of a spherical shell in an upper indentation of the sleeve receiving a firing pin and the firing pin by all-round deflection of the release lever can be operated.
Dabei besitzt die Hülse eine den Durchmesser erweiternde Ausdrehung, und am unteren Ende des Schlagbolzens befindet sich ein Kugelkäfig sowie in diesem eine Eindrehung, in die die Kugeln von der Hülsenwandung gedrückt werden. Zwischen dem Käfig und einer oberen Einziehung ist die Feder angeordnet und am oberen Ende des Schlagbolzens ein Sicherungsstift mit dem der Schlagbolzen gespannt wird. In dessen Führung weist die Hülse längsverlaufende Schlitze auf, die vor Zutritt von Verschmutzung durch eine äußere, mit dem Sicherungsstift verbundene Manschette beim Spannen mitverschoben wird.The sleeve has a diameter-widening recess, and at the lower end of the firing pin there is a ball cage and in this a recess into which the balls are pressed by the wall of the sleeve. The spring is arranged between the cage and an upper retraction and at the upper end of the firing pin a locking pin with which the firing pin is tensioned. In its guide, the sleeve has longitudinal slots which, when it is tightened, are also displaced before contamination by an outer sleeve connected to the securing pin.
Der Bolzen wird soweit gegen die Federkraft gespannt, bis die Kugeln in die Ausdrehung ausweichen können und den Bolzen über an einen an die Eindrehung anschließenden Zylinderteil sichern.The bolt is tensioned against the spring force until the balls can escape into the recess and secure the bolt via a cylinder part that adjoins the recess.
Diese Vorrichtung weist Nachteile auf. Zum einen ist die Montage des Kugelkäfigs ausgesprochen kompliziert, da dieser erst bis zur Ausdrehung gegen die Feder hochgeschoben werden muß, um den Schlagbolzen durch die Einziehung hindurch zu montieren. Zum anderen können die Kugeln nach innen lediglich bis zur Eindrehung bewegt werden, wobei zwischen dieser und der inneren Hülsenwandung nur geringes Spiel besteht, was leicht zum Verklemmen durch Verschmutzung und zu Nichtzündung oder Nichtauslösung führen kann.This device has disadvantages. On the one hand, the assembly of the ball cage is extremely complicated, since it only has to be pushed up against the spring until it is unscrewed in order to mount the firing pin through the retraction. On the other hand, the balls can only be moved inwards until they are screwed in, whereby there is only slight play between this and the inner sleeve wall, which can easily lead to jamming due to contamination and to non-ignition or non-triggering.
Darüber hinaus ist die Hülse in entspanntem Zustand durch die Manschette nicht verdeckt und somit offen für Zutritt von Schmutzteilchen, die wiederum die Funktion beeinträchtigen können.In addition, the sleeve is not covered by the sleeve in the relaxed state and is therefore open to the entry of dirt particles, which in turn can impair the function.
Die vorliegende Erfindung hat sich demgegenüber die Aufgabe gestellt, eine derartige Auslösevorrichtung zu schaffen, die einfacher aufgebaut und zu montieren ist, und die ein von Verschmutzungen unabhängige höhere Funktionssicherheit gewährleistet.In contrast, the present invention has set itself the task of creating such a triggering device, which is simpler in construction and assembly, and which ensures greater functional reliability independent of contamination.
Die Lösung dieser Aufgabe gelingt bei einer Auslösevorrichtung für durch Stolperdrähte oder dergleichen auslösende pyrotechnische, gegebenenfalls mit einem Anzündhütchen ausgerüstete, mechanische oder elektrische Signale, bestehend aus einer Hülse mit an deren Kopf kugelig gelagertem Auslöseteller und einer Aufnahmevorrichtung für den Stolperdraht sowie einer durch Kugeln und einen Auslösenocken betätigbaren, einen federbelasteten Schlagbolzen mit Sicherungsstift aufweisenden Schlagwerk, erfindungsgemäß dadurch, daß der Auslösenocken auf einem Nockenhalter angeordnet ist, gegen den koaxial ein Kegelstift mit an dem Kegel anschließendem Zylinder anliegt, der mit dem Nockenhalter nicht verbunden ist, und wobei Nockenhalter und Kegelstift in einer kopfseitigen Bohrung des Schlagbolzens liegen und im Bereich der Bohrung des Schlagbolzens sich deren Wandung durchgreifende Öffnungen befinden, in denen zwei oder mehr Kugeln angeordnet sind, die in gespanntem Zustand der Feder gegen die Zylinderfläche des Kegelstiftes anliegen, und wobei der Schlagbolzen dabei kopfseitig von einem Trichterkragen mit sich in Auslöserichtung verjüngendem Konus umfaßt ist, an dessen Innenwandung die Kugeln in gespanntem Zustand der Vorrichtung ebenfalls anliegen, wobei sich hierbei in gesichertem Zustand der Vorrichtung der Kegelstift auf dem Sicherungsstift abstützt.This object is achieved with a triggering device for pyrotechnic signals that trip through trip wires or the like, optionally equipped with a primer, mechanical or electrical signals, consisting of a sleeve with a ball-shaped trigger plate on its head and a receiving device for the trip wire, and one with balls and one Trigger cam actuatable, a spring-loaded firing pin with locking pin striking mechanism, according to the invention in that the trigger cam is arranged on a cam holder against which a taper pin coaxially abuts with the cylinder adjacent to the cone, which is not connected to the cam holder, and wherein cam holder and taper pin in a head-side bore of the firing pin and in the region of the bore of the firing pin there are openings penetrating the wall, in which two or more balls are arranged, which in the tensioned state of the spring it bears against the cylindrical surface of the taper pin, and the firing pin is enclosed on the head side by a funnel collar with a cone tapering in the direction of release, on the inner wall of which the balls also rest in the tensioned state of the device, the taper pin being in a secured state of the device supports the locking pin.
Dabei kann die axiale Führung des Schlagbolzens in einfacher Weise durch einen an den Trichterteil des Trichterkragens anschließenden und an dem Bolzen anliegenden zylindrischen Abschnitt geschehen.The firing pin can be axially guided in a simple manner by a cylindrical section adjoining the funnel part of the funnel collar and abutting the bolt.
Bei der erfindungsgemäßen Auslösevorrichtung wird nach der Entfernung des Sicherungsstiftes durch den Nockenhalter der Kegelstift in die entsprechend lange Bohrung geschoben, und die Kugeln können nach innen in den so geschaffenen Freiraum ausweichen, so daß sie die Innenwandung beim Herabbewegen des Schlagbolzens nicht berühren und somit ein Verklemmen sicher verhindert ist.In the release device according to the invention, the taper pin is pushed into the correspondingly long bore after the locking pin has been removed by the cam holder, and the balls can deflect inwards into the free space thus created, so that they do not touch the inner wall when the firing pin is moved down and thus jam is safely prevented.
Zur Montage braucht lediglich nach dem Einsetzen des Kegelstiftes der Schlagbolzen soweit gegen die zuvor eingelegte Feder hochgedrückt zu werden, daß die Kugelaufnahme oberhalb des Trichterkragens frei liegen und so die Kugeln bequem eingelegt werden können. Beim Entspannen der Feder werden die Kugeln von den Öffnungen mitgenommen und vom Trichter soweit radial gegen die Zylinderfläche des Kegelstiftes gedrückt, um so den Schlagbolzen in diesem vorgespannten Federzustand zu halten. In dieser Lage wird auch der Sicherungsstift in dafür vorgesehene, gegenüberliegend angeordnete Hülsenbohrungen geschoben, wonach der Kegelstift auf dem Sicherungsstift aufliegt. Die Auslösung der Vorrichtung entspricht derjenigen des obengenannten Standes der Technik.For assembly, the firing pin only needs to be pushed up against the previously inserted spring after the taper pin has been inserted so that the ball receptacle is exposed above the funnel collar and the balls can thus be inserted comfortably. When the spring is released, the balls are taken away from the openings and pressed radially against the cylindrical surface of the taper pin by the funnel so as to keep the firing pin in this prestressed spring state. In this position, the locking pin is also pushed into the sleeve bores provided for this purpose, and the taper pin rests on the locking pin. The triggering of the device corresponds to that of the above-mentioned prior art.
In besonders eleganter Weise ist die Hülse in ein Unterteil und ein Oberteil unterteilt, die miteinander verschraubt werden, wobei das Oberteil eingekröpft ist und hier der oben ausgerundete Auslöseteller anliegt.In a particularly elegant manner, the sleeve is divided into a lower part and an upper part, which are screwed together, the upper part being cranked and the release plate rounded off at the top.
Das Musterteil trägt wiederum oben den Trichterkragen, der durch einfaches Eindrehen des oberen Randes der den Nockenhalter und den Kegelstift aufnehmenden Bohrung hergestellt werden kann, und außen das zur Verschraubung von Oberteil und Unterteil der Hülse dienende Gewinde aufweist, so daß die zu montierenden Teile ungehindert zusammengebaut werden können.The sample part in turn carries the top of the funnel collar, which can be made by simply screwing in the upper edge of the bore receiving the cam holder and the taper pin, and has the outside thread for screwing the upper part and lower part of the sleeve, so that the parts to be assembled are assembled unhindered can be.
Der Schlagbolzen trägt erfindungsgemäß einen unteren Anschlag, der zur Hülsenwandung jedes gewünschte Spiel aufweisen kann, und zwischen welchem und einer unterhalb des Sicherungsstiftes bzw. dessen quer zur Längsachse der Vorrichtung verlaufenden Einführungsbohrungen für den Sicherungsstift eine Einziehung besitzt, zwischen welchen die Feder in Spannung gehalten wird bzw. über welche die Feder unter Entspannung den Schlagbolzen bewegt.According to the invention, the firing pin has a lower stop, which can have any desired play on the sleeve wall, and between which and an insertion bores for the locking pin running below the locking pin or, respectively, transverse to the longitudinal axis of the device, has a recess between which the spring is held in tension or via which the spring moves the firing pin while relaxing.
Der Sicherungsstift kann in einfacher Weise durch einen Splint oder dergleichen sowie eine gegenüberliegende Durchmesserverbreiterung vor unbeabsichtigtem Herausziehen geschützt werden. Auf der dem Splint gegenüberliegenden Seite kann eine Kordel für eine Fernentsicherung befestigt werden.The locking pin can be protected in a simple manner by a split pin or the like and an opposite diameter widening against unintentional pulling out. A cord for remote security can be attached to the side opposite the cotter pin.
Die Auslöse- bzw. Stolperdrähte werden erfindungsgemäß auf neuartige Weise mit der Auslösevorrichtung verbunden. Dabei ist der Auslöseteller an einem Gewindebolzen angeordnet, der eine obere und eine untere mit dessen Gewinde kämmende, vorzugsweise gerändelte, Scheibe trägt, zwischen die eine Zwischeneinlage eingelegt ist. Nach dem Lösen einer Rändelmutter können einer oder zwei, unter beliebigen Winkeln sich kreuzende Drähte zwischen Zwischeneinlage und obere und untere Rändelmütter geklemmt werden, wobei sich die Drähte in die Zwischeneinlage eindrücken, wozu diese aus nachgiebigem Material, wie insbesondere Kunststoff, gebildet ist. Die Rändelung dient dem besseren Erfassen, z.B. mit Handschuhen.According to the invention, the trigger or trip wires are connected to the trigger device in a novel manner. The trigger plate is arranged on a threaded bolt which carries an upper and a lower, meshing, preferably knurled, disc with its thread, between which an intermediate insert is inserted. After loosening a knurled nut, one or two wires crossing at any angle can be clamped between the intermediate insert and the upper and lower knurled nuts, the wires pressing into the intermediate insert, for which purpose they are made of flexible Material, such as plastic in particular, is formed. Knurling is used for better grasping, e.g. with gloves.
Letztlich wird vorgeschlagen, den Kegelstift beidendig mit an den Zylinderabschnitt anschließenden Kegeln zu versehen, so daß er in beliebiger Ausrichtung montiert werden kann.Ultimately, it is proposed to provide the taper pin on both ends with cones adjoining the cylinder section, so that it can be mounted in any orientation.
Anhand der beiliegenden Figur wird die vorliegende Erfindung näher erläutert.The present invention is explained in more detail with reference to the attached figure.
Die Vorrichtung weist eine in ein Unterteil 1 und ein Oberteil 2 unterteilte Hülse auf, die kopfseitig eingezogen ist. Gegen die Einziehung liegt innen der oben ausgerundete Auslöseteller 3 an, an den sich der Gewindebolzen 7 anschließt. Auf diesen sind die Rändelscheiben 4 und 6 aufgeschraubt und klemmen zwischen sich die vorzugsweise aus Kunststoff gefertigte Zwischeneinlage 5 ein, wobei zwischen diesen die Stolperdrähte 23 verklemmt werden.The device has a sleeve subdivided into a
An das Hülsenunterteil ist der Trichterkragen 16 angeformt. Dieser springt gegenüber dem Außendurchmesser der Hülse 1, 2 zurück und trägt außen das zur Verschraubung mit dem Innengewinde des Oberteils dienende Außengewinde. Der Trichter des Trichterkragens verjüngt sich nach innen unten.The
Die Darstellung zeigt die Vorrichtung in gespanntem, gesichertem Zustand. An den Trichterteil des Trichterkragens schließt sich ein zylindrischer Abschnitt an, der sich bis zum Anschlag 21 für die Feder 15 fortsetzt und den innen liegenden Schlagbolzen 10 führt. Letzterer weist oben eine koaxiale Bohrung 14 auf. In diese Bohrung greift von oben zunächst der Nockenhalter 12, der mit dem an dem Auslöseteller 3 anliegenden Nocken 9 verbunden ist. Der Nockenhalter liegt von oben an dem unteren Kegel des Kegelstiftes 13 an, dessen unterer Kegel ruht auf dem Sicherungsstift 11. Dicht unterhalb des oberen Kegels des Kegelstiftes ist der Schlagbolzen 10 im Bereich der Bohrung 14 durchbrochen, und in diesem Durchbruch liegen die Kugeln 8, welche vom Trichter des Trichterkragens gegen den Zylinderabschnitt des Kegelstiftes radial nach innen gedrückt werden und den Schlagbolzen 10 bei gespannter Feder halten.The illustration shows the device in a tensioned, secured state. A cylindrical section adjoins the funnel part of the funnel collar, which continues up to the

Nach Entfernung des Splintes 20 kann der Sicherungsbolzen 11 von Hand ergriffen oder über eine Kordel 22 herausgezogen werden. Danach ist die Vorrichtung scharf. Wird nun der Gewindebolzen 7 ausgelenkt (Auslösekraft 14-15 N), wobei eine Auslenkung bei bevorzugter Abmessung von 10° einen Tellerrandausschlag von 1,5 mm bewirken, so wird im selben Maße über den Nockenhalter 12 der Kegelstift nach unten gedrückt. Die Kugeln 8 gelangen in den Bereich des Kegels und werden vom Trichterkragen nach innen gedrückt. Die Bohrung 14 ist dabei so bemessen, daß der Kegelstift soweit nach unten fallen kann, daß die Kugeln beim Abwärtsbewegen völlig frei sind von der an den Trichterkragen 16 nach unten anschließenden Führung des Schlagbolzens 10.After removing the split pin 20, the securing
