Description

Die Erfindung bezieht sich auf einen Feuerwerkskörper und insbesondere auf ein Bühnenfeuerwerk gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a firework and in particular to a stage firework according to the preamble of claim 1.

Mit Feuerwerkskörpern läßt sich eine Vielzahl optischer und akustischer Effekte erreichen, die auch dazu benutzt werden, Bühnenshows und andere Veranstaltungen, z.B. Popkonzerte, Fernsehshows, Zirkus- und Varieté-Darbietenn insbesondere optisch zu "untermalen". Die Effekte werden durch einen Wirkstoff, in der Regel eine Mischung mehrerer Komponenten erzeugt, z.B. Pulversatzen, Buntpulvern, Effektstoffen usw. Eine Vielzahl derartiger Wirkstoffkomponenten kann in der gewünschten Mischung nicht über lange Zeit gelagert werden. Das Bühnenfeuerwerk wird daher von einem Feuerwerker unmittelbar vor der Bühnenshow installiert: Die einzelnen Komponenten werden gemischt und die Mischungen in Behälter gefüllt, die dann am gewünschten Ort der Bühne plaziert und mit einer üblicherweise elektrisch ansteuerbaren Zündvorrichtung ausgerüstet werden. Die Zündvorrichtungen aller Behälter werden mit einer Zentrale verkabelt und können von dort von dem Feuerwerker während der Bühnenshow angesteuert werden.Fireworks can be used to achieve a variety of optical and acoustic effects, which are also used to stage shows and other events, e.g. Pop concerts, television shows, circus and variety shows, especially to "visually" underline. The effects are generated by an active ingredient, usually a mixture of several components, e.g. Powder sets, colored powders, effect substances, etc. A large number of such active ingredient components cannot be stored for a long time in the desired mixture. The stage firework is therefore installed by a fireworker immediately before the stage show: the individual components are mixed and the mixtures are filled into containers, which are then placed at the desired location on the stage and equipped with a usually electrically controllable ignition device. The ignition devices of all containers are wired to a control center and can be controlled from there by the fireworker during the stage show.

Diese Installation ist sehr aufwendig.This installation is very complex.

Aus der DE-C-555744 ist eine Blitzlichtpatrone bekannt, die einen Behalter mit mehreren abgeschlossenen Kammern aufweist, in denen jeweils eine Wirkstoffkomponente aufgenommen ist. Die beiden Kammern können gegeneinander so verdreht werden, daß sie in einer Drehstellung über eine Öffnung miteinander in Verbindung stehen. Damit können die beiden Komponenten vermischt werden. In dem gemeinsamen Mischraum reicht dann eine Zündvorrichtung hinein, die über eine Kabel mit einer Steuereinrichtung verbunden ist.From DE-C-555744 a flash cartridge is known which has a container with several closed chambers, in each of which an active ingredient component is accommodated. The two chambers can be rotated relative to one another so that they are connected to one another via an opening in a rotational position. This allows the two components to be mixed. An ignition device then extends into the common mixing space and is connected to a control device via a cable.

Dieses in diesem Patent vorgestellte Prinzip kann auch für Feuerwerkskörper verwendet werden, so daß dort die einzelnen Wirkstoffkomponente jeweils in Kammern eines abgeschlossenen Behälters aufgenommen sind, die durch Trennwände voneinander abgeteilt sind. Die Komponenten können sich daher nicht miteinander vermischen, so daß der Behälter praktisch unbegrenzt gelagert werden kann. Hiermit entfallen bei der Vorbereitung für ein Bühnenfeuerwerk alle Arbeiten für die Präparation der Wirkstoffmischung unmittelbar vor dem Einsatz des Feuerwerkes.This principle presented in this patent can also be used for fireworks, so that there the individual active ingredient components are each accommodated in chambers of a closed container, which are separated from one another by partitions. The components can therefore not mix with each other, so that the container can be stored practically indefinitely. This eliminates all the preparation work for the mixture of active ingredients immediately before the fireworks are used in preparation for a stage firework.

Beider oben erwähnte Blitzlichtpatrone gemäß der DE-C-555744 sind keine Vorkehrungen vorhanden, um die Patrone in einer gewünschten Lage zu fixieren.In the above-mentioned flash cartridge according to DE-C-555744, there are no precautions to fix the cartridge in a desired position.

Es ist allerdings aus der GB-A-1580579 ein Feuerwerkskörper für Bühnenfeuerwerk bekannt, der einen Behälter aufweist, in dem ein Wirkstoff aufgenommen ist, der durch eine Zündladung elektrisch zu zünden ist. Die Zündladung ist mit zwei Kontaktstiften am Boden des Behälters verbunden, die in eine elektrische Steckdose eingesteckt werden können. Die elektrische Steckdose kann über eine Steuereinrichtung so angesteuert werden, daß die Zündladung des Feuerwerkskörpers zündet und damit ein gewünschter akustischer Effekt erzeugt wird.From GB-A-1580579, however, a firework for stage fireworks is known, which has a container in which an active substance is received, which can be ignited electrically by an ignition charge. The primer charge is connected to two contact pins on the bottom of the container, which can be plugged into an electrical socket. The electrical socket can be controlled by a control device so that the ignition charge of the fireworks ignites and thus a desired acoustic effect is generated.

Bei diesem Feuerwerkskörper sind mehrere getrennte Kammern zur Aufnahme von nicht zusammen lagerfähigen Wirkstoffen nicht vorgesehen. Außerdem sind die Steckkontakte ungeschützt.In this firework, several separate chambers for receiving active ingredients that cannot be stored together are not provided. The plug contacts are also unprotected.

Der Erfindung liegt die Aufgabe zugrunde, einen Feuerwerkskörper gemäß dem Oberbegriff des Patentanspruches 1 anzugeben, mit der die Installation von Feuerwerkskörpern insbesondere bei Bühnenshows, und die elektrische Ansteuerung von mehreren plazierten Feuerwerkskörpern vereinfacht wird.The invention has for its object to provide a firework according to the preamble of claim 1, with which the installation of fireworks, in particular in stage shows, and the electrical control of several placed fireworks is simplified.

Diese Aufgabe ist gemäß der Erfindung durch die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmale gelöst.This object is achieved according to the invention by the features specified in the characterizing part of patent claim 1.

Durch die Ausgestaltung des Behälters mit zwei Kammern, die durch eine folienartige Wand voneinander getrennt sind, kann durch einfaches Verschieben des Einsatzes, in dem die eine Kammer aufgenommen ist, die Trennwand durchtrennt werden, so daß sich ein gemeinsamer Mischraum bildet. Durch diese Verschiebung wird der Feuerwerkskörper auch für die elektrische Ansteuerung einsatzbereit gemacht. Der Steckkontakt ist sowohl bei dem unbenutzten Behälter als auch bei dem zum Einsatz vorbereiteten Behälter geschützt.Due to the design of the container with two chambers, which are separated from each other by a film-like wall, the partition can be severed by simply moving the insert in which the one chamber is accommodated, so that a common mixing space is formed. This shift also makes the fireworks ready for electrical control. The plug contact is protected both for the unused container and for the container prepared for use.

Der Behälter kann mit diesem Steckkontakt entweder direkt oder über ein Verlängerungskabel in eine Steckbuchse z. B. in einer Steckbuchsenleiste eingesteckt werden, die ihrerseits vorzugsweise über Steckkabel elektrisch mit einer Steuerzentrale verbunden ist. Mit Steuersignalen von der Zentrale aus können dann die einzelnen Feuerwerkskörper gezündet werden. Durch eine derartige Anordnung werden auch die Arbeiten der elektrischen Installation vereinfachtThe container can either with this plug contact either directly or via an extension cable into a socket. B. be plugged into a socket strip, which in turn is preferably electrically connected to a control center via plug cables. The individual fireworks can then be ignited with control signals from the control center. Such an arrangement also simplifies the work of the electrical installation

is a schematic representation of several installed fireworks according to the invention.

Ein Feuerwerkskörper 1 gemäß Fig. 1 weist einen zylindrischen Behälter 2 auf, der etwa in der Mitte durch eine Querwand 3 unterteilt ist, die den Boden einer Hauptkammer 4 für eine Komponente 5 eines Wirkstoffes bildet. Die Oberseite des Behälters und damit auch die Hauptkammer ist durch eine Folie 6, z. B. eine Aluminiumfolie abgeschlossen.A firework 1 according to FIG. 1 has a cylindrical container 2, which is divided approximately in the middle by a transverse wall 3, which is the bottom of a main chamber 4 for one Component 5 of an active ingredient forms. The top of the container and thus the main chamber is covered by a film 6, for. B. completed an aluminum foil.

Mit dem Boden 3 der Hauptkammer ist ein mit dem Behälter koaxialer zylindrischer Ansatz 7 verbunden, der etwa bis zur Unterseite des Behälters 2 reicht. Die Oberseite dieses Ansatzes ist mit einer Folie 8, z. B. einer Aluminiumfolie, abgedeckt, die dort ebenfalls als Boden der Hauptkammer 4 dient.A cylindrical extension 7 coaxial with the container is connected to the bottom 3 of the main chamber and extends approximately to the underside of the container 2. The top of this approach is with a film 8, z. B. an aluminum foil, which also serves as the bottom of the main chamber 4.

In den Ansatz 7 ist ein Rohrstutzen 9 eingeschoben, der durch eine Querwand 10 unterteilt ist. Der der Folie 8 zugewandte Raum des Rohrstutzens 9 dient als zweite oder Nebenkammer 11 zur Aufnahme einer zweiten Komponente 12 eines Wirkstoffes. In die Querwand 10 ist eine elektrische Zündvorrichtung 13 eingeschraubt, die aus einer in die Nebenkammer ragenden Zündpille 14 und einem von der Querwand 10 nach unten ragenden, mit der Zündpille elektrisch verbundenen Klinkenstecker 15 besteht.In the approach 7, a pipe socket 9 is inserted, which is divided by a transverse wall 10. The space of the pipe socket 9 facing the film 8 serves as a second or secondary chamber 11 for receiving a second component 12 of an active ingredient. An electrical ignition device 13 is screwed into the transverse wall 10 and consists of a squib 14 projecting into the secondary chamber and a jack plug 15 projecting downward from the transverse wall 10 and electrically connected to the squib.

Der Rohrstutzen 9 weist an seinem unteren Rand eine Verdickung 16 auf, die in eine Nut 17 am unteren Rand des Rohrstutzens 9 eingreift, so daß der Rohrstutzen sicher in dem Ansatz 7 gehalten ist. Der Ansatz 7 ist zudem mit einem Schraubdeckel 18 mit einem nach unten ragenden Flansch 19 verschlossen, der auch den Klinkenstecker 15 abdeckt.The pipe socket 9 has at its lower edge a thickening 16 which engages in a groove 17 at the lower edge of the pipe socket 9, so that the pipe socket is held securely in the neck 7. The approach 7 is also closed with a screw cap 18 with a downwardly projecting flange 19 which also covers the jack plug 15.

Der obere,der Folie 8 zugewandte Rand des Rohrstutzens 9 verläuft leicht schräg und bildet eine Schneidkante 20 zum Durchschneiden der Folie 8.The upper edge of the pipe socket 9 facing the film 8 is slightly inclined and forms a cutting edge 20 for cutting through the film 8.

Zur Installation des Feuerwerkskörpers wird der Schraubdeckel 18 abgeschraubt und verkehrt herum mit dem Flansch 19 in den Ansatz 7 gesteckt. Durch entsprechenden Druck wird hierbei auch der Rohrstutzen 9 nach oben geschoben, wobei die Schneidkante 20 die Folie 8 auftrennt; vgl. Fig. 2. Die Verdickung 16 schnappt am Ende der Bewegung in eine weitere Nut 21 in dem Ansatz 7 ein, so daß der Rohrstutzen 9 in seiner Endlage wiederum fixiert ist. Der Schraubdeckel 18 wird dann aus dem Ansatz 7 herausgezogen.To install the firework, the screw cap 18 is unscrewed and inserted upside down with the flange 19 in the neck 7. The pipe socket 9 is also pushed upwards by appropriate pressure, the cutting edge 20 separating the film 8; see. Fig. 2. The thickening 16 snaps at the end of the movement in a further groove 21 in the neck 7, so that the pipe socket 9 is in turn fixed in its end position. The screw cap 18 is then pulled out of the neck 7.

Durch leichtes Schütteln des Behälters werden die Komponenten 5 und 12 des Wirkstoffes miteinander vermischt.The components 5 and 12 of the active ingredient are mixed with one another by gently shaking the container.

Der Behälter 2 wird anschließend auf eine Steckbuchse 22 aufgesetzt, die den Klinkenstecker 15 aufnimmt. Ein Anschluß über ein Verlängerungskabel 23 ist ebenfalls möglich; vgl. Fig. 3. Mehrerer solcher Steckbuchsen können auf einer Steckbuchsenleiste 24 zusammengefaßt sein. Jede Steckbuchsenleiste 24 ist mit einer Steuerzentrale 25 verbunden, von der aus jede Steckbuchse 22 angesteuert werden kann. Die Ansteuerung kann auch über einen mit der Steuerzentrale 25 verbundenen Fußschalter 26 erfolgen.The container 2 is then placed on a socket 22 which receives the jack plug 15. A connection via an extension cable 23 is also possible; see. Fig. 3. Several such sockets can be summarized on a socket strip 24. Each socket strip 24 is connected to a control center 25, from which each socket 22 can be controlled. The control can also take place via a foot switch 26 connected to the control center 25.

Wie in Figur 1 gestrichelt angedeutet, kann in der Hauptkammer 4 noch ein präpariertes Papprohr 27 auf einen Hals des Ansatzes 7 aufgesteckt werden, um zusätzlich zu sonstigen Effekten einen Knall zu erzeugen.As indicated by dashed lines in FIG. 1, a prepared cardboard tube 27 can be placed in the main chamber 4 on a neck of the attachment 7 in order to produce a bang in addition to other effects.

Um die Feuerwerkskörper nach deren Installation zu zünden, wird von der Steuerzentrale ein Zündimpuls zur Zündpille geschickt, so daß der Wirkstoff aus den beiden Komponenten zündet. Durch den beim Abbrennen des Wirkstoffes wachsenden Innendruck im Behälter birst die Folie 6. Jetzt werden die optischen und ggf. akustischen Effekte wirksam.In order to ignite the fireworks after their installation, the control center sends an ignition pulse to the squib so that the active substance ignites from the two components. The film 6 bursts due to the increasing internal pressure in the container when the active substance burns off. The optical and possibly acoustic effects now take effect.
