Definitions

  • the invention relates to pyrotechnic articles and ammunitions which can be used by hand, also referred to as irritation casting bodies, for generating one or more lightning and / or blast effects which preferably form no or at least no severe or lethal lesions causing fragments when used as intended.
  • So-called Irritationsschharm consist of a cylindrical container with one or more effect set chambers and radially and / or head and / or bottom side openings arranged through which the resulting pressure can escape during proper implementation (see DE 10 2010 052 210 A1, DE 10 2010 052 209 A1, EP 1 212 578 B1, DE 10 2004 059 991 B4).
  • the dam necessary for achieving the or the lightning and / or blast effects is achieved by mechanical closure of the above-described relief s openings of the container by means of no or at least no lethal acting fragments forming components.
  • the effect set chamber (s) in Irritationsschöge- tion unit are filled with a powdery or granulated pyrotechnic mixture, which arranged on a Anzündverzöge- tion unit consisting of a retarding element with a crimped or caulked primer, or a directly pressed into the cylindrical container delay line with a above , inflated or caulked primer, is lit.
  • the initiation of the ignition chain is done with hand thrown pyrotechnic articles and ammunition usually via a built-in toggle unit, preloaded firing pin.
  • the simplest conceivable solution for increasing transport and storage safety is the reduction in the number of ammunitions per packaging unit and / or the use of correspondingly more massive and heavy transport and storage containers.
  • the smallest packaging unit should also serve as a transport container for the ammunition under operating conditions to use; this also applies in particular to irritation objects. Accordingly, a reduction in the number of ammunition per packaging einheii and / or the use of more massive, heavy and bulky transport and storage containers such use, especially in the fight off.
  • the solution is based on the object to take precautions to reduce at a strong increase in the outside temperature on the ignition temperature of the pyrotechnic mixture of the ignition primer the occurring due to the improper implementation of a Irritationssch endeavors pressure build-up.
  • Another object of the invention is to provide provisions to prevent the accumulation of many such Irritationssch redesignn, z. B. in a transport or storage container, with excessive increase in the outside temperature, z. B. by fire to avoid damage and / or endangering the environment.
  • Another object is to make the Irritationssch redesign so that they comply with the intended use in terms of fragment freedom, light output and sound pressure.
  • the propellant charge is phlegmatized in case of fire by adding an inert material which melts when the thermal load is excessive, so that a separation of the projectile from the drive is prevented.
  • the phlegmatizing acting inert material can also be accommodated separately in a tubular component which projects openly into the propellant charge chamber and, in the event of fire, phlegmatizes the propellant charge by wetting by means of melting.
  • the cylindrical container 1 can be closed to the outside by a cover 7 (all figures) or the like Depending on the effect to be achieved, the container 1 can have one or more effect set chambers 6 with openings 8 arranged radially and / or bottom and / or on the top side
  • pyrotechnic ammunitions of the Applicant are DE 9210649 U1, DE 9213375 U1, DE 9213376 U1, DE 19944468 C2, DE 102004059991 B4 od he DE 102008058776 A 1 removable.
  • FIG. 3a-c shows a schematic longitudinal section through an irritation throwing body 20 ", consisting of a container 1 with an effect set chamber 6 with bottom and head side arranged openings 8 and arranged on the upper end side rocker arm unit 2, which receives a Anzündmechanismus 3 with a firing pin, is, wherein the Irritationssch endeavor of two screwed, separately storable and transportable assemblies 1, 2 consists.
  • the containers 1 are provided with at least one channel 9 per effect set chamber 6, which tapers outwardly from the inner wall of the container 1, the channel 9 / channels 9 being fusible, fixed Material z. B. is closed in the form of a rivet / rivets / are.
  • the channel 9 can / channels 9 can be arranged radially and / or bottom and / or head side and can / have either a conical profile or a step profile.
  • At least one of the radially modified and / or bottom-side and / or top-side openings 8 of corresponding unmodified containers is extended by countersunk holes, so that the inset inserts 12 are secured by means of clamping rings or annular discs or perforated screws (FIG ) are mechanically fixed over the openings from a fusible, solid material 13.
  • the cross-section of the openings of the clamping rings or annular discs or perforated screws corresponds to the necessary to provide the performance parameters relief cross section.
  • the introduction of channels 9 according to the figures 1a - 1d can additionally be made if this is desired. Otherwise, this embodiment has the charm that only the reworking of the openings 8 is necessary.
  • the irritation body 20 is designed to present a lightning and / or pop effect, from the two separately storable and transportable assemblies 1" and 2 ", which form a functional irritation throwing body 20" by simply screwing both assemblies together
  • An assembly 1 consists of the cylindrical container 1 with radially and / or bottom and / or top side arranged openings for receiving - here an effect charge 6.
  • the cylindrical container 1 can be closed by a coating 7 or the like to the outside Assembly 2 "consists of the Kipphebeitician 2 with the ignition mechanism 3 includes at least one firing pin, the priming cap 4 with ignition charge and a central delay set 5.
  • the central delay set acting as an amplifier set 10 housed pyrotechnic mixture.

Abstract

L'invention concerne des articles et des munitions pouvant être employés manuellement, destinés à produire un ou plusieurs effets d'éclair et/ou de détonation, et qui, en cas d'usage approprié, forment des fragments ne causant pas de blessures ou du moins pas de blessures graves ou mortelles. La sécurité de stockage, de transport et de manipulation de ces projectiles irritants est augmentée selon l'invention par intégration de composants en matériau solide et fusible dont la température de fusion est inférieure à la température d'inflammation spontanée des constituants pyrotechniques de la munition.
