Definitions

  • the invention relates to a fireworks device for generating a total effect consisting of individual effects.
  • Bengallanzen be fixed to a frame. Until such a frame can be ignited due to its own weight exclusively on the ground.
  • the invention has for its object to improve a fireworks device for generating a total effect consisting of individual effects.
  • the object is solved by the features of claim 1.
  • the gist of the invention is that multiple tracer effect bodies that leave a trail of light when ascending serve as single effects to represent a total effect.
  • the overall effect is, for example, a graphic symbol, in particular a smiley or a heart.
  • the overall effect can also be a character, in particular a letter or a number.
  • the overall effect may be a multi-letter word, and more particularly a letter or a multi-digit number. It is possible to create arbitrary graphics and symbols.
  • the single effects represent single pixels, the overall effect being an overall image resulting from the individual pixels.
  • the tracer effect body can also be designed without subsequent tracer track. In such an embodiment, the single effect consists of the ascending pixel.
  • the fireworks device according to the invention is fired in the air and is not limited to use as ground fireworks.
  • the tracer effect bodies are arranged as a fireworks device, in particular spatially relative to one another, such that the individual effects represent the overall effect.
  • Each tracer effect body has an ignition element and a light-emitting charge, wherein the lighted charge ignited by the ignition element represents the pixel with a light trace.
  • the fireworks device comprises an ignition control for, in particular staggered, ignition of the tracer luminous body.
  • the ignition control is connected to the ignition elements of the tracer effect body.
  • the alignment of the light-track effect body is irrelevant, since the tracer of the luminous charge is visible regardless of the orientation of the tracer luminous effect body when ascending for the viewer. The risk of a misrepresentation is prevented.
  • the tracer effect bodies are ignited with a time delay in order to ensure that the individual effects are arranged at different distances along the access direction.
  • the tracer effect bodies are fixed in a fireworks body. It is particularly advantageous if the tracer effect bodies are arranged at different angles of inclination to one another in the fireworks body.
  • a fireworks device in which the tracer effect bodies are arranged in a fireworks body enables the combination of the tracer effect bodies to an object.
  • Such a fireworks body corresponds to a so-called battery, which is placed on a base. In the battery, the tracer effect bodies are attached. It is not possible to extract the individual tracer effect bodies from the fireworks body without destroying the firecracker.
  • a fireworks device in which the tracer effect body has an ignition sleeve having a longitudinal axis ensures a reliable and error-prone Ignition.
  • the ignition sleeve is in particular designed as a hollow cylinder. There are also other hollow profile design of the ignition possible.
  • the ignition element and the light-emitting charge are arranged in the ignition sleeve.
  • the ignition sleeve protects the ignition element and the luminous charge from the weather, moisture and / or accidental damage.
  • it is particularly preferred to form the fireworks device such that (in the assembled state) the ignition sleeve is aligned at an angle of 0 ° to 70 °, in particular 15 ° to 45 °, with respect to the horizontal.
  • the fireworks device in such a way that (in the assembled state) the ignition sleeves are aligned in such a way that vertically aligned effects can be generated.
  • the luminous bodies are oriented vertically (perpendicular) in a plane such that an image appearing at the top and bottom at the same distance relative to the position of the device is produced.
  • the lower squibs must be charged less than that for the upper part of the image to produce different flight times t up to a predetermined pixel.
  • a fireworks device in which the mass and / or volume of the ignition charge of at least two tracer effect bodies are set differently, ensures a variably settable rise height of the luminous charge.
  • the ascending overall effect during the upgrade can change in geometry, in particular stretch or compress its contour. It is possible that the ascending total effect with different rise heights of the individual effects will be extinguished at the same time, ie in particular if the individual effects have reached their respective individual rise height.
  • different tracing points of the individual illuminating charges can be generated to a respective pixel in a vertical image.
  • the flight times t are essentially determined by the angle of the ignition sleeve relative to the horizontal.
  • the tracer effect bodies are in particular fixed in the housing, for example by gluing or by mechanical holding means. Such a firecracker is error-prone and easy to use and especially for non pyrotechnic trained end user usable.
  • the tracer effect bodies are arranged in particular in a housing of the fireworks body.
  • a fireworks device in which a detonating cord section of the detonating cord determines the time offset between two trailing-edge effect bodies to be fired adjacent to one another, ensures an immediate and uncomplicated definition of the temporal sequence of the ascending tracer-light effect bodies.
  • a fireworks device in which the detonating cord section is connected, in particular directly, to the detonating elements of the illuminated track effect bodies to be ignited, is designed so as to be error-prone.
  • Such a fireworks device may also correspond to the maximum allowable in Class II for fireworks height of rise.
  • Fireworks class II correspond to New Year's fireworks and are available to consumers.
  • a fireworks device may also have a tracer effect body whose luminous charge has a lower riser height of, for example, 5m to 15m.
  • a tracer effect body is designed in particular in the form of a Roman light.
  • a Roman light is typically detonated while it is being held, that is, out of hand.
  • the fireworks device can be designed in such a way that the tracer effect bodies can be arranged variably with respect to one another.
  • the fireworks device does not form a uniform fireworks body and is intended in particular for the use of pyrotechnically trained professionals.

Due to the fact that the holding quantities are flexible and changeable, the fireworks device itself is not a single pyrotechnic article which would require a separate CE approval according to the European directives or an approval of the Federal Institute for Materials Research and Testing (BAM). Only the tracer effect bodies themselves require CE approval. For generating the overall effect, the individual tracer effect bodies are combined by a pyrotechnically trained specialist, whereby no new pyrotechnic article is produced.
