Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Erzeugung von Blitz- und/oder Knalleffekten, wie sie bei Militär- oder von Sicherheitskräften eingesetzt werden.The present invention relates to a device for generating lightning and/or bang effects, such as are used by military or security forces.

Solcherart Vorrichtungen werden als stationäre Objekte sowie als Wurfkörper ausgeführt. Sie können Blitz- und/oder Knalleffekte erzeugen, um entweder als Täuschkörper zu wirken, für defensive Abwehr oder zu Simulations- und Trainingszwecken.Such devices are designed as stationary objects and as projectiles. They can create lightning and/or bang effects to act either as decoys, for defensive defence, or for simulation and training purposes.

Bekannterweise enthalten Vorrichtungen dieser Art einen pyrotechnischen Satz, welcher durch Zündung die gewünschten Blitz- und/oder Knalleffekte hervorrufen kann. Dieser pyrotechnische Satz wird üblicherweise in einer Hochdruckkammer untergebracht und besitzt Ausbringöffnungen, durch welche die gewünschten Effekte aus der Vorrichtung ausgebracht werden. Dazu werden die vorhandenen Öffnungen in der Vorrichtung durch Verschlussscheiben abgedichtet, damit der pyrotechnische Satz nicht bis zu seiner Zündung in seiner Funktionsfähigkeit durch Eindringen von Feuchtigkeit beeinträchtigt wird.As is known, devices of this type contain a pyrotechnic charge which can cause the desired flash and/or bang effects by ignition. This pyrotechnic charge is usually housed in a high-pressure chamber and has discharge openings through which the desired effects are discharged from the device. For this purpose, the existing openings in the device are sealed by sealing discs, so that the functionality of the pyrotechnic charge is not impaired by the ingress of moisture until it is ignited.

Ein solches Abdichten durch Verschlussscheiben ist beispielsweise in der DE 10 2010 052 210 A1 gezeigt. Diese Druckschrift offenbart einen Irritationskörper mit einem pyrotechnischen Satz, welcher nach Zündung Effekte hervorruft, die durch die Ausblassöffnungen ausgebracht werden. Die Ausblassöffnungen sind vor der Zündung des Irritationskörpers durch Verschlusselemente, beispielsweise leichte Pappscheiben, verschlossen.Such a seal by means of closure discs is, for example, in DE 10 2010 052 210 A1 shown. This publication discloses an irritation body with a pyrotechnic charge which, after ignition, causes effects that are discharged through the exhaust openings. Before the irritation body is ignited, the outlet openings are closed by means of closure elements, for example light cardboard discs.

Diese Verschlussscheiben werden üblicherweise aufwendig mit einem Kleber gegen Feuchtigkeit abgedichtet. Pro Öffnung muss eine Verschlussscheibe eingesetzt werden, sodass beim Körper mit beispielsweise acht Öffnungen oder acht Effektladungen auch mindestens acht Verschlussscheiben eingesetzt werden müssen. Ebenso viele Öffnungen müssen durch den genannten Kleber gegen Feuchtigkeit abgedichtet werden.These sealing discs are usually sealed against moisture with an adhesive, which is expensive. One locking disk must be used per opening, so that at least eight locking disks must also be used in the case of a body with, for example, eight openings or eight effect charges. The same number of openings must be sealed against moisture by the adhesive mentioned.

Bei der Herstellung solcher Vorrichtungen zur Erzeugung von Blitz- und/oder Knalleffekten muss jede Öffnung der Vorrichtung, durch welche der Effekt nach Zündung der Wirkladung ausgebracht werden soll, durch eine der oben genannten Verschlussscheiben verschlossen werden. Zusätzlich muss pro Verschlussscheibe jede Öffnung mit einem Kleber gegen Feuchtigkeit abgedichtet werden.In the manufacture of such devices for generating lightning and/or bang effects, each opening in the device through which the effect is to be applied after the active charge has been ignited must be closed by one of the above-mentioned sealing discs. In addition, each opening for each sealing disc must be sealed against moisture with an adhesive.

Aus der US 8 161 883 B1 ist ferner eine Vorrichtung zur Erzeugung von Blitz- und Knalleffekten bekannt, bei der die Ausblasöffnungen mittels einer äußeren Hülle wasserdicht verschlossen sind, um die enthaltene pyrotechnische Mischung zu schützen.From the U.S. 8,161,883 B1 a device for generating lightning and bang effects is also known, in which the blow-out openings are sealed watertight by means of an outer shell in order to protect the pyrotechnic mixture contained.

Aufgabe der vorliegenden Erfindung ist es somit, den Aufwand zum Abdichten einer solchen Vorrichtung zu verringern und das Aufbringen eines Klebers zum Abdichten unnötig zu machen.It is therefore the object of the present invention to reduce the outlay for sealing such a device and to make the application of an adhesive for sealing unnecessary.

Diese Aufgabe wird durch Merkmale des Hauptanspruchs gelöst. Erfindungsgemäß besitzt dazu die Vorrichtung zur Erzeugung von Blitz- und/oder Knalleffekten einen Körper, der die äußere Hülle der Vorrichtung darstellt. Im Inneren dieses Körpers ist ein Hochdruckladeraum vorgesehen, in welchem ein pyrotechnischer Satz angeordnet ist. Ebenso gibt es einen Außenraum außerhalb des Körpers und mindestens zwei Überströmquerschnitte, durch welche der Hochdruckladeraum mit dem Außenraum verbunden ist.This object is solved by features of the main claim. According to the invention, the device for generating lightning and/or bang effects has a body that represents the outer shell of the device. Inside this body there is a high-pressure charge chamber in which a pyrotechnic charge is placed. There is also an exterior space outside the body and at least two overflow cross-sections through which the high-pressure charge space is connected to the exterior space.

Zur Abdichtung der Vorrichtung wird nun mindestens eine Berstmembran vorgesehen, um den Hochdruckladeraum gegenüber dem Außenraum fluiddicht abzuschließen. Die Berstmembran ist dabei so gestaltet, dass sich beim Zünden oder Zerlegen des pyrotechnischen Satzes im Hochdruckladeraum durch Gasgenerierung ein Druck aufbaut, welcher auch auf die Berstmembran wirkt.At least one bursting membrane is now provided to seal the device, in order to seal off the high-pressure loading space in a fluid-tight manner from the outside space. The bursting membrane is designed in such a way that when the pyrotechnic charge is ignited or disintegrated in the high-pressure charge chamber, gas generation builds up pressure, which also acts on the bursting membrane.

Die Berstmembran kann hierbei einen geschlossenen oder einen geöffneten Zustand einnehmen. Der geschlossene Zustand liegt nach Fertigung der Vorrichtung vor und bewirkt das Abdichten des Hochdruckladeraums mit dem pyrotechnischen Satz gegenüber dem Außenraum außerhalb des Körpers.The bursting membrane can assume a closed or an open state. The closed state is present after the device has been manufactured and causes the high-pressure charge chamber with the pyrotechnic charge to be sealed off from the outside space outside the body.

Die Berstmembran kann vom geschlossenen in den geöffneten Zustand übergehen, nämlich bei Einwirkung von Druck oder Wärme auf die Berstmembran. Dazu ist die Berstmembran so gestaltet, dass ab einem gewissen Druck die Berstmembran geöffnet wird. Ebenso kann sie so gestaltet sein, dass ab einer gewissen Temperatur die Berstmembran verdampft oder verbrennt, sodass sie ebenfalls in einen geöffneten Zustand übergeht.The bursting membrane can change from the closed to the open state, namely when pressure or heat is applied to the bursting membrane. For this purpose, the bursting membrane is designed in such a way that the bursting membrane opens at a certain pressure. It can also be designed in such a way that the bursting membrane vaporizes or burns above a certain temperature, so that it also changes to an open state.

Erfindungsgemäß stellt die Berstmembran die Umhüllung des Hochdruckladeraums dar. Da die Berstmembran dazu den Hochdruckladeraum komplett umhüllt, gewährleistet diese Anordnung die beste Verdämmung der Vorrichtung.According to the invention, the bursting membrane represents the encasing of the high-pressure loading space. Since the bursting membrane completely encloses the high-pressure loading space, this arrangement ensures the best damming of the device.

Vorteilhafterweise bewirkt das Abdichten durch Bestmembrane ebenfalls eine Verdämmung des Hochdruckladeraums. Durch diese Verdämmung wird zum einen der Hochdruckladeraum stabilisiert, zum anderen können durch diese Verdämmung auch die gewünschten Knalleffekte hervorgerufen werden.Advantageously, sealing with Bestmembrane also causes the high-pressure loading space to be blocked. On the one hand, this damming stabilizes the high-pressure loading space, and on the other hand, the desired bang effects can also be caused by this damming.

Zur Abdichtung der Vorrichtung gegenüber Eindringen von Fluid in den pyrotechnischen Satz besteht die Berstmembran aus einem Material oder Materialmix welcher fluidundurchlässig ist. Als Material kann hierbei Kunststoff oder Aluminiums vorgesehen sein.To seal the device against the ingress of fluid into the pyrotechnic charge, the bursting membrane consists of a material or material mix which is impermeable to fluids. Plastic or aluminum can be provided as the material here.

Die Beschaffenheit der Berstmembran kann dabei abhängig von der Anwendung ausgestaltet sein. Die Berstmembran kann dazu durch das verwendete Material oder Materialmix auf die jeweilige Anwendung der Vorrichtung eingestellt werden, sodass die Berstmembran ab einem bestimmten Druck bzw. einer bestimmten Temperatur vom geschlossenen in den geöffneten Zustand übergeht.The nature of the bursting membrane can be designed depending on the application. For this purpose, the bursting membrane can be adjusted to the respective application of the device by the material or material mix used, so that the bursting membrane changes from the closed to the open state from a certain pressure or a certain temperature.

Bevorzugter Weise werden metallische und nicht metallische Werkstoffe sowie Kombinationen aus beiden vorgeschlagen. Insbesondere wird gummiertes Aluminium für die Berstmembran vorgeschlagen, da dies eine einfache und günstige Herstellung gewährleistet und einfach zu bearbeiten ist.Metallic and non-metallic materials and combinations of both are preferably proposed. In particular, rubberized aluminum is proposed for the bursting membrane, since this ensures simple and inexpensive manufacture and is easy to process.

Der Körper der Vorrichtung kann sowohl rotationssymmetrisch als auch quaderförmig ausgestaltet sein.The body of the device can be configured both rotationally symmetrical and cuboid.

Bevorzugter Weise sind weiterhin Mittel zum Entzünden und/oder Zerlegen des pyrotechnischen Satzes vorgesehen, damit die erfindungsgemäße Vorrichtung bzw. der pyrotechnische Satz gezündet und/oder zerlegt werden kann. Die erfindungsgemäße Vorrichtung kann somit als eigenständiger, stationärer Körper oder Wurfkörper ausgestaltet sein und einen entsprechenden Zünder besitzen. Die Vorrichtung kann aber auch als Modul zur Einbringung in einen Wurfkörper eingesetzt werden.Means for igniting and/or breaking down the pyrotechnic charge are preferably also provided so that the device according to the invention or the pyrotechnic charge can be ignited and/or broken down. The device according to the invention can thus be designed as an independent, stationary body or projectile body and have a corresponding igniter. However, the device can also be used as a module for introduction into a projectile.

Die Berstmembran kann erfindungsgemäß so gestaltet sein, dass nach dem Übergang aus dem geschlossenen in den geöffneten Zustand und Entweichen des Druckes aus dem Hochdruckladeraum, die Berstmembran wieder in den geschlossenen Zustand zurückgeführt wird. Ebenso kann die Berstmembran so gestaltet sein, dass diese beim Öffnen permanent verformt wird. Bei der vorgenannten bevorzugten Ausführungsform der Berstmembran aus gummiertem Aluminium wird beispielsweise eine permanente Verformung herbeigeführt.According to the invention, the bursting membrane can be designed in such a way that after the transition from the closed to the open state and the pressure escaping from the high-pressure charge chamber, the bursting membrane is returned to the closed state. The bursting membrane can also be designed in such a way that it is permanently deformed when it is opened. In the aforementioned preferred embodiment of the rubberized aluminum bursting membrane, for example, a permanent deformation is brought about.

Es ist auch eine Ausführungsform vorgesehen, bei welcher mehrere Hochdruckladeräume und/oder mehrere pyrotechnische Sätze vorgesehen sind. So sind Ausführungsformen möglich, bei welchen ein Hochdruckladeraum mit mehreren pyrotechnischen Sätzen vorhanden ist sowie mehrere Hochdruckladeräume mit jeweils einem oder mehreren pyrotechnischen Sätzen. Bei Vorhandensein mehrerer Hochdruckladeräume können dann auch mehrere Mittel zum Entzünden und/oder Zerlegen des pyrotechnischen Satzes vorgesehen sein.An embodiment is also envisaged in which multiple high pressure charge chambers and/or multiple pyrotechnic charges are provided. Thus, embodiments are possible in which there is a high-pressure charge chamber with a plurality of pyrotechnic charges and a plurality of high-pressure charge chambers, each with one or more pyrotechnic charges. If there are several high-pressure charging chambers, then several means for igniting and/or breaking down the pyrotechnic charge can also be provided.

Figur 1 und 2 zeigen eine beispielhafte, nicht erfindungsgemäße Vorrichtung zur Erzeugung von Blitz- und/oder Figure 1 and 2 show an exemplary, non-inventive device for generating flash and / or

Knalleffekten mit jeweils zwei Berstmembranen 5, welche an den Außenabmessungen des Körpers 1 angeordnet sind. Bei Figur 1 sind Überströmquerschnitte 4 in Längsrichtung des Körpers 1 angeordnet und bei Figur 2 sind die Überströmquerschnitte 4 in Querrichtung des Körpers 1 angeordnet. Es sind jeweils vier Überströmquerschnitte 4 gezeigt, wobei jeweils zwei der Überströmquerschnitte 4 durch eine Berstmembran 5 abgedeckt sind.Pop effects, each with two bursting membranes 5, which are arranged on the outer dimensions of the body 1. at figure 1 are overflow cross sections 4 arranged in the longitudinal direction of the body 1 and at figure 2 the overflow cross sections 4 are arranged in the transverse direction of the body 1 . Four overflow cross sections 4 are shown in each case, two of the overflow cross sections 4 being covered by a bursting membrane 5 in each case.

Im Inneren des Körpers 1 ist ein Hochdruckladeraum 2 angeordnet, welcher einen pyrotechnischen Satz 3 enthält.Inside the body 1 there is a high-pressure charge chamber 2 containing a pyrotechnic charge 3 .

Die Berstmembrane 5 sind im geschlossenen Zustand gezeigt und dichten somit den Hochdruckladeraum 2 mit dem pyrotechnischen Satz 3 fluiddicht ab. In der Vorrichtung der Figuren 1 und 2 ist gleichzeitig der Körper 1 abgedichtet, da die Berstmembrane 5 am Außenmaß des Körpers 1 angeordnet sind.The bursting membranes 5 are shown in the closed state and thus seal the high-pressure charge chamber 2 with the pyrotechnic charge 3 in a fluid-tight manner. In the device of Figures 1 and 2 the body 1 is sealed at the same time, since the bursting membranes 5 are arranged on the outer dimension of the body 1.

Wird nun der pyrotechnische Satz 3 gezündet und/oder zerlegt, wird durch Gasbildung bei der Zerlegung bzw. bei dem Abbrand Druck im Hochdruckladeraum 2 erzeugt. Die Überströmquerschnitte 4 verbinden den Hochdruckladeraum 2 mit dem Außenraum außerhalb des Körpers 1, sodass der im Hochdruckladeraum befindliche Druck sich auch auf die Berstmembrane 5 auswirkt.If the pyrotechnic charge 3 is then ignited and/or disassembled, pressure is generated in the high-pressure charge chamber 2 as a result of gas formation during the disassembly or during the burn-up. The overflow cross-sections 4 connect the high-pressure charge chamber 2 to the outside space outside of the body 1, so that the pressure in the high-pressure charge chamber also affects the bursting membrane 5.

Die Berstmembrane 5 können so ausgestaltet sein, dass entweder ab einem bestimmten Druck die Berstmembrane 5 vom geschlossenen in den geöffneten Zustand übergehen oder sie können so gestaltet sein, dass durch die Wärmeentwicklung ab einer gewissen Temperatur die Berstmembrane 5 vom geschlossenen in den geöffneten Zustand übergehen.The bursting membrane 5 can be designed in such a way that either the bursting membrane 5 changes from the closed to the open state from a certain pressure or they can be designed in such a way that the bursting membrane 5 changes from the closed to the open state as a result of the heat development from a certain temperature.

Nach Öffnen der Berstmembrane 5 kann das erzeugte Gas aus dem Hochdruckladeraum 2 durch die Überströmquerschnitte 4 nach außerhalb des Körpers 1 entweichen und entsprechende Blitz- und/oder Knalleffekten erzeugen. Der Knalleffekt kann auch dadurch hervorgerufen oder unterstützt werden, dass die Berstmembran 5 vom geschlossenen in den geöffneten Zustand übergeht. Durch den dann schlagartigen Druckaustausch kann ein Knalleffekt hervorgerufen werden.After the bursting membrane 5 has opened, the gas produced can escape from the high-pressure charge chamber 2 through the overflow cross-sections 4 to the outside of the body 1 and generate corresponding lightning and/or bang effects. The bang effect can also be caused or supported by the fact that the bursting membrane 5 changes from the closed to the open state. The sudden exchange of pressure can cause a bang.

Figur 3 und 4 zeigen ebenfalls eine beispielhafte, nicht erfindungsgemäße Vorrichtung, wobei hierbei im Gegensatz zu Figur 1 und 2 die Berstmembrane 5 nicht am Außenmaß des Körpers 1 angeordnet sind, sondern am Hochdruckladeraum 2. Somit ist in dieser Vorrichtung nur der Hochdruck Laderaum 2 fluiddicht abgedichtet und nicht der Körper 1, da weiterhin Fluide in den Körper eindringen können, nämlich durch die Überströmquerschnitte 4. Auch in den Figuren 3 und 4 sind jeweils zwei der Überströmquerschnitte 4 von einer Berstmembran 5 verschlossen. Figure 3 and 4 also show an exemplary device not according to the invention, in contrast to Figure 1 and 2 the bursting membrane 5 is not arranged on the outer dimension of the body 1, but on the high-pressure charge chamber 2. Thus, in this device only the high-pressure charge chamber 2 is sealed in a fluid-tight manner and not the body 1, since fluids can still penetrate into the body, namely through the overflow cross-sections 4. Also in the Figures 3 and 4 two of the overflow cross sections 4 are closed by a bursting membrane 5.

Der übrige Aufbau und die Wirkweise der Vorrichtung in Figur 3 und 4 entspricht denjenigen der Figur 1 und 2.The rest of the structure and the mode of operation of the device in Figure 3 and 4 corresponds to those of Figure 1 and 2 .

In Figur 5 und 6 ist die Berstmembran 5 erfindungsgemäß als vollständige Umhüllung des Hochdruckladeraums 2 gezeigt. Somit ist nur eine Berstmembran in den Figuren 5 und 6 vorhanden.In Figure 5 and 6 the bursting membrane 5 is shown according to the invention as a complete envelopment of the high-pressure charge space 2 . Thus, only one bursting membrane in the Figures 5 and 6 present.

Dadurch, dass die Berstmembran 5 die komplette Umhüllung des Hochdruckladeraums 2 darstellt, wird mit nur einer Berstmembran der Hochdruckladeraum 2 sowie der darin enthaltene pyrotechnische Satz 3 fluiddicht abgeschlossen, da die eine Berstmembran 5 durch diese Anordnung jeden Überströmquerschnitt 4 verschließt.Due to the fact that the bursting membrane 5 completely encloses the high-pressure charge chamber 2, the high-pressure charge chamber 2 and the pyrotechnic charge 3 contained therein are fluid-tightly sealed with just one bursting diaphragm, since the one bursting diaphragm 5 closes each overflow cross-section 4 with this arrangement.

Auch in den Figuren 5 und 6 sind der übrige Aufbau der Vorrichtung sowie auch die Funktion der vorangegangenen Figuren gleich.Also in the Figures 5 and 6 the rest of the structure of the device as well as the function of the previous figures are the same.

Anhand der beispielhaften, nicht erfindungsgemäßen Vorrichtungen der Figuren 7 und 8 wird schließlich gezeigt, wie die Berstmembran innerhalb des Körpers 1 so verlaufen kann, dass auch wie in den vorangegangenen Zeichnungen 1 bis 4 mehrere Überströmquerschnitte 4 mit einer Berstmembran 5 abgedichtet werden können.Based on the exemplary, non-inventive devices Figures 7 and 8 Finally, it is shown how the bursting membrane can run inside the body 1 in such a way that, as in the previous drawings 1 to 4, several overflow cross sections 4 can be sealed with a bursting membrane 5.

Das Einbringen der Berstmembran 5 in den Körper 1 nach Figur 7 und 8 kann bei der Montage der Vorrichtung geschehen oder dadurch, dass Einschübe bzw. Nuten vorgesehen sind, in welche nach Herstellung der Vorrichtung, die Berstmembrane 5 eingeschoben werden. Insbesondere bei dieser Vorrichtung hat sich Gummi als Material oder Materialbestandteil der Berstmembran 5 als hilfreich erwiesen.The introduction of the bursting membrane 5 in the body 1 after Figure 7 and 8 This can be done during assembly of the device or by providing inserts or grooves into which the bursting membrane 5 can be inserted after the device has been manufactured. In this device in particular, rubber has proven to be helpful as a material or material component of the bursting membrane 5 .

Allen vorangegangenen Figuren gemein ist, dass jeweils mehrere Überströmquerschnitte 4 mit einer Berstmembran 5 abgedeckt werden. Die Berstmembran 5 befindet sich jeweils nach Fertigung einer Vorrichtung im geschlossenen Zustand, sodass der Hochdruckladeraum 2 mit dem pyrotechnischen Satz 3 fluiddicht abgeschlossen ist. Dadurch kann auch die erfindungsgemäße Vorrichtung bis zu ihrem Einsatz gelagert werden, ohne dass die Wirkung des pyrotechnischen Satzes 3 durch eindringende Feuchtigkeit beeinflusst wird.What all the preceding figures have in common is that several overflow cross sections 4 are each covered with a bursting membrane 5 . The bursting membrane 5 is in the closed state after a device has been manufactured, so that the high-pressure charge chamber 2 with the pyrotechnic charge 3 is sealed off in a fluid-tight manner. As a result, the device according to the invention can also be stored until it is used without the effect of the pyrotechnic charge 3 being affected by the ingress of moisture.

Der Einsatz von Klebemitteln wie er aus dem Stand der Technik bekannt ist, ist bei dieser Art von Abdichtung nicht notwendig, da durch die Art der Einbindung bzw. Anbringung der Berstmembran 5 an der Vorrichtung bereits eine entsprechende Abdichtung gewährleistet ist.The use of adhesives, as is known from the prior art, is not necessary with this type of seal, since the type of integration or attachment of the bursting membrane 5 to the device already ensures a corresponding seal.

Die Vorrichtung ist nicht auf die oben genannten Merkmale beschränkt. Vielmehr sind weitere Ausgestaltungen denkbar. So ist es möglich, den gesamten Körper durch eine Berstmembran zu umhüllen. Ebenso ist es denkbar, die Berstmembran so zu gestalten, dass sie rückstandsfrei bei Überführung aus dem geschlossenen den geöffneten Zustand verbrennt.The device is not limited to the features mentioned above. Rather, further configurations are conceivable. It is thus possible to enclose the entire body with a bursting membrane. It is also conceivable to design the bursting membrane in such a way that it burns without leaving any residue when transferred from the closed to the open state.
