Definitions

  • the invention relates to a smoke grenade, in particular a smoke hand grenade, with a housing in which smoke-generating material is located, and a detonator which comprises at least one detonator charge extending in the axial direction centrally into the housing, as for example in DE3048595 A described.
  • a smoke hand grenade in which the smoke-generating material consists of a multiplicity of stacked, disk-shaped or disk-sector-shaped thin flakes (flares), each of which is coated with a smoke active ingredient based on red phosphorus.
  • An aluminum can serves as the housing of the well-known hand grenade.
  • an irritation body can be removed, which is intended to exert an irritation or shock effect on a person.
  • Individual chambers with an effect charge are arranged around a central chamber.
  • a delay set is placed in the central chamber.
  • the invention is based on the object of specifying a smoke grenade, in particular a smoke hand grenade, which, compared with known smoke grenades, enables simpler and more cost-effective manufacture and in which a large number of different customer-specific requirements can be taken into account in a simple manner.
  • the invention is essentially based on the idea that the housing—similar to a drum revolver for receiving the cartridges—several radially evenly tubular recesses which are arranged around at least one igniter charge and each extend axially parallel to the igniter charge and which are filled with the mist-generating material.
  • the fog-generating material consists of, for example, a red phosphorus-based fog substance.
  • the smoke-generating material is preferably pressed into stackable pellets which are arranged in a form-fitting manner in the tubular recesses of the housing of the smoke grenade.
  • simple RP granules can also be used.
  • the mist-generating material is filled into the tubular recesses in the form of flares.
  • the combustion speed of the pellets varies, for example through a combination of continuous and spontaneous fog output.
  • variable layering of RP pellets and optionally RP granules and the RP flares takes place within the tubular, preferably round, recesses of the housing.
  • the recesses can also have a shape other than round and can, for example, be triangular, square or hexagonal, i.e. polygonal. The shape of the pellets or flares should be chosen accordingly.
  • a cavity for accommodating additives or secondary charges, such as irritant gas, but also other RP pellets, RP flares, is provided between the side wall of the housing and the bursting charge.
  • a smoke grenade with a housing containing smoke-generating material is therefore proposed.
  • the smoke grenade comprises a detonator head or detonator and a detonator charge extending in the axial direction centrally into the housing.
  • the housing has a plurality of tubular recesses which are arranged radially, preferably uniformly, around the igniter charge and each extend axially parallel to the igniter charge. These are filled with a fog-generating material.
  • the recesses are connected via webs to a central tube that carries the igniter charge.
  • the housing of the smoke grenade with the recesses and cavities etc. is preferably made of plastic and can be produced as a one-piece component using the injection molding process will. By using, for example, colored plastic, additional painting of the housing is not necessary.
  • the smoke grenade has the advantage that it is possible to increase the effective mass while reducing the total weight at the same time.
  • a combination of continuous and spontaneous fog output is possible by introducing RP flares or RP granules.
  • Fig.1 1 denotes a smoke hand grenade according to the invention, which comprises a housing 2, preferably made of plastic, and an igniter 3 screwed into the housing 2, here an igniter head.
  • the fuse head 3 carries a delay element 11 in the center, often a delay charge. This delay element 11 interacts with at least one ignition decomposition charge 4 extending in the axial direction centrally in the housing 2 .
  • the housing 2 has several, at least two, in the example shown ten, tubular recesses 5 arranged radially evenly around the igniter charge 4 and each extending axially parallel to the igniter charge 4 .
  • Each recess 5 is filled with a mist-generating material 6, respectively.
  • the recesses 5 are connected via thin or narrow webs 12 to a central tube 13 which carries the igniter charge 4 .
  • Such a shape of the housing 2 can be easily produced by a plastic injection molding process. As a result, longitudinal grooves 15 can also be injected into the housing 2 .
  • the smoke-generating material 6 is, for example, stackable pellets 61 made from a smoke substance based on red phosphorus, which are preferably arranged in a form-fitting manner in the tubular recesses 5 of the housing 2 of the hand grenade 1 .
  • At least one cavity 8 for accommodating additives or secondary charges is provided between the inner side wall 7 of the housing 2 and the ignition decomposition charge 4 .
  • This at least one cavity 8 is delimited from above by the detonator head 3 and from below by a closure cover 14 .
  • the closure cap 14 can be screwed on in the simplest form.
  • the central tube 13 has an internal thread.
  • a percussion primer is initiated in a known manner after pulling a safety pin by actuating the ring trigger 9 and releasing a safety lever 10 by triggering a fuse head mechanism (unspecified). This in turn activates the delay element 11. After a delay time has elapsed, this ignites the igniter charge 4. The igniter charge ignites the pellets 61 and, if appropriate, a secondary charge located in the at least one cavity 8. At the same time, the housing 2 is disassembled by the gas formation and the pellets 61 are thrown radially outwards. The pellets 61 burn and create an opaque fog cloud.
  • the invention is not limited to smoke grenades, but can also be used, for example, with smoke grenades that can be fired from grenade launchers, so-called smoke mortar shells. A fuse suitable for these grenades must then be used.
