Definitions

  • the invention relates to a firework and in particular to a stage firework according to the preamble of claim 1.
  • 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.
  • a flash cartridge 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.
  • 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.
  • a firework for stage fireworks 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.
  • 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.
  • 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.
  • the 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the components 5 and 12 of the active ingredient are mixed with one another by gently shaking the container.
  • 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.
  • 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.
  • 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.
