  • cake boxes or fireworks batteries are offered in prefabricated version.
  • the most important disadvantage of this solution is the choreography and effect sequence specified by the manufacturer, which can not be changed. Furthermore, it is known that the ignition system of such cake boxes is unreliable and the fireworks come to a standstill when extinguishing the internally processed fuses. Furthermore, it can never be ruled out that the burn-up process will resume after exposure, whereby the safety is not guaranteed. Another disadvantage is that the cake box remains as a residue and is not reusable.
  • a major safety disadvantage of the Cake Box is that it fires the effects in any position and location, as well as after falling over, destruction by jamming or standing upside down.
  • Professionally organized fireworks regularly use starting devices to produce their own effect sequence in place of said cake boxes, in which a finite number of starting tubes is first equipped with an ignition system of several sections of fuses and / or - litzen, then the discharge rate in the form of powder filled and Finally, the effect and possibly supplementary delay rates are introduced.
  • This method requires a considerable manufacturing effort, since the timing of the ignition system must first be ensured by selecting the type and length of fuses and at the same time the ignition safety.

An individual determination of the start intervals (ignition delay) is not possible with this system, since these are already predetermined by the structure of the rocket. Likewise, certain pyrotechnic effects, such as fire pots or comets, are not feasible with this system.

  • delay sets are described in DE 1 9 56 872 B and DE 24 04 870 C2. Their construction is, however, enormously cost-intensive and therefore a use in pyrotechnic objects for fireworks is already excluded. closed.
  • the arrangements proposed in the above-mentioned documents are only suitable for functioning within a system of a signal rocket.
  • the delay sets are an integral part of the pyrotechnic effect (the rocket) and have no influence on its start delay. The user has no possibility to decide on an individual ignition delay immediately before use.

  • Bearing (69) has laterally an integrally formed dome (77), which has a bearing (71) mirror-inverted dome (78) connection.
  • the dividing line (79) of the dome (77) and (78) can be rectilinear, but also have a profiling to increase the tightness at the contact surfaces.
  • connections (70) and (80) as well as the domes (77) and (78) receive the transmission means described above, which serve to transfer the combustion gases from one store to the next.
  • the described arrangement is made of plastic and modules are produced with an odd or even number of bearings.
  • the tabs (73) and (75) By assembling using the tabs (73) and (75), a multiple arrangement is created which allows starting devices with a fixed number of bearings and in which the number of bearings necessary for the performance of large-scale professional fireworks can be provided.
  • the starting devices thus obtained can be transported either in the form of individual modules or assembled, are very light and allow trouble-free burning of fireworks even in bad weather conditions.
  • the pyrotechnic article located there can be fired by introducing a first ignition means into a bore of the bearing (68).
  • a first ignition means into a bore of the bearing (68).
  • the combustion gases pass into bearings (69) and ignite the pyrotechnic article located there, which in turn fired via the dome (77) and (78) and the resulting compound fired in the camp (71) pyrotechnic article and this in turn located in the camp (72). If there is a juxtaposition of a plurality of bearings, this process can be continued from the first to the last camp.

Abstract

L'invention concerne un système pyrotechnique, des objets pyrotechniques compatibles au système et un procédé d'allumage et de tir adapté au système. Ce système comprend un dispositif de lancement comportant une pluralité de compartiments respectivement dotés d'un canal de liaison inter-compartiments. Ces compartiments contiennent les objets pyrotechniques. Le premier compartiment est pourvu d'un dispositif d'allumage supplémentaire et l'objet pyrotechnique contenu dans ce premier compartiment est allumé. Un moyen d'allumage placé à l'extérieur sur l'objet pyrotechnique guide l'énergie d'allumage dans cet objet et simultanément dans le compartiment adjacent par le canal de liaison. L'objet pyrotechnique se trouvant dans le compartiment adjacent est alors allumé. Le moyen d'allumage situé à l'extérieur sur l'objet pyrotechnique provoque en partie un retard d'allumage. Le temps de retard se règle par la rotation de l'objet pyrotechnique par rapport au canal de liaison. L'association d'un dispositif de lancement et d'objets pyrotechniques sélectionnés en liaison avec le réglage du temps de retard permet de créer la chorégraphie d'un feu d'artifice.
