Definitions

  • a pyrotechnic device for creating an overall effect consisting of individual effects comprises: a) several tracer effect bodies, each having, i. an ignition element, and ii. at least one flare charge, and, b) an ignition control being connected with the ignition elements to ignite the tracer effect bodies, wherein said tracer effect bodies are arranged so that the ascending flare charges each create an individual effect of the overall effect, wherein the tracer effect bodies are disposed within a pyrotechnic article, and wherein said tracer effect bodies are arranged in the pyrotechnic article with different angles of inclination to one another.
  • FIG. 1 is a schematic lateral view of a pyrotechnic device according to a first exemplary embodiment with an overall effected created thereby;

  • FIG. 7 is an exemplary representation of an overall effect which can be created using the pyrotechnic device according to FIG. 4 .
  • the gist of the claimed subject matter resides in the aspect that several tracer effect bodies, which leave a tracer while ascending, serve as individual effects to create an overall effect.
  • the overall effect for instance, is a graphic symbol, in particular a smiley or a heard.
  • the overall effect can also be a character, in particular a letter or a number.
  • the overall effect can be a word composed of several letters, and in particular a writing or a multi-digit number. It is possible to create arbitrary graphic representations and symbols.
  • the individual effects display individual scene elements, whereby the overall effect is an overall picture consisting of the individual scene elements. Due to the aspect that the individual effect is visible to the viewer as a scene element with a following tracer during the ascent of the tracer effect body, the overall effect is visible for a comparably long period of time.
  • the tracer effect body can also be designed without a following tracer. In such an embodiment, the individual effect consists of the ascending scene element.
  • the inventive pyrotechnic device is launched and is not confined to the use as a ground firework.

  • Each tracer effect body has an ignition element and a flare charge, wherein the flare charge being ignited by the ignition element displays the scene element with the tracer.
  • the pyrotechnic device comprises an ignition control to ignite, in particular in a temporally offset manner, the tracer effect body. Said ignition control is connected with the ignition elements of the tracer effect bodies.
  • the orientation of the tracer effect bodies is not of relevance, since the tracer of the flare charge is visible to the viewer during the ascent independently of the orientation of the tracer effect body. The risk of a faulty picture is prevented.

  • the lower ignition charges have to be charged less heavily than those for the upper part of the picture so as to create different flying times t up to a predetermined scene element.
  • a pyrotechnic device in which the mass and/or volume of the priming charge of at least two tracer effect bodies is/are set differently ensures a variably settable ascent height of the flare charge.
  • the ascending overall effect can change its geometry during the ascent, in particular can stretch or shrink its contour. It is possible that the ascending overall effect extinguishes simultaneously with different ascent heights of the individual effects, i.e. in particular if the individual effects have each reached their respective ascent height.
  • Due to the at least two tracer effect bodies with differently set priming charges different flying times t of the individual flare charges can be created at a corresponding scene element in a vertical picture. The flying times t are determined essentially by the angle of the ignition sleeve relative to the horizontal.

Merely the tracer effect bodies as such do require CE approval. For creating the overall effect, the individual tracer effect bodies are combined by a pyrotechnically trained professional, whereby a new pyrotechnical article is not created.
