Definitions

  • the invention relates to a cartridge made of plastic after this Preamble of claim 1.
  • Such (propellant) cartridges made of plastic are in Shot guns, especially bolt guns of the most varied Species used. Here are the cartridges mostly integrated in magazine strips (cartridge tape magazine). Plastic cartridges can can also be used in central firearms. The advantages of plastic cartridges are in particular the relatively low material and manufacturing costs; the cartridges can be manufactured using spray technology.
  • the above-mentioned plastic cartridge or Cartridge tape magazine made of plastic is known from EP 37 79 24 A1.
  • Plastic materials have, e.g. Metal one much lower strength. This results in the problem of material extrusion for plastic materials as a result of the propellant or combustion Powder charge resulting gas pressures.
  • a material extrusion can occur anywhere where the cartridge receiving closure of the shooting device, that is space surrounded by cartridge storage and closure bottom, is not closed. With a cartridge magazine strip operated shooting devices have e.g. not one closed closure because the magazine strip in the area of his just picked up by the cartridge store Cartridge on two sides of the closure from the Cartridge storage is led out, and that over narrow Gaps between the cartridge storage and the bottom of the breech.
  • Cartridges should also be used, especially plastic cartridges with led out of the cartridge store Flanges or the like Be provided with extensions, around the cartridge for removal from the cartridge store after ignition of the load (manually or automatically) to be able to grab.
  • the problem of material extrusion arises especially with such shooting devices, where the shot tube with its front end on the Area into which the bolt is to be driven, put on and the cartridge bearing against the bottom of the closure is pressed (unlocked lock).
  • the invention has for its object a space-saving plastic cartridge to create, which can be integrated into magazine strips can also be used in central firearms, and which at Adequate stability and use of less rigid plastics Has strength of the cartridge wall without a material extrusion in Transition area from cover to sleeve body should take place or the Gas tightness at the end of the cartridge body on the cover side is impaired should be.
  • the invention inter alia uses a plastic cartridge of the type mentioned, in which the flange of the cartridge body in the section in which it is in Direction of propagation that occurs when the propellant charge is ignited Pressure wave runs, at least over part of this section - in Direction of propagation - tapered.
  • the tapered on the Cartridge body molded flange in thickness with increasing distance from the cartridge body, and not necessarily all of it Extension in the direction of the gas pressure and thus towards the maximum load on the flange, however at least in sections. Accordingly, it is also on the device side the space between cartridge storage and Closure bottom, in which the flange is located, at least sections wedge-shaped tapering outwards educated.
  • the invention is based on the knowledge that also plastic materials in a tapered channel or space when pressure is exerted on the cross section larger end to be pinched can (wedge gap principle for plastic plastic materials, applied to propellant cartridges made of plastic). Due to the clamping effect Friction in the tapered channel occurs cross-sectionally smaller end no material.
  • Plastic to reduce the pressure in the material can tapering in the direction of propagation of the gas pressure wave Flange between the metallic cartridge bearings and the metallic closure bottom, which between corresponding to the tapered flange form a tapering space or channel that at Record shot occurring gas pressures without a Material extrusion takes place.
  • the flange of the cartridge body at least in sections from a flange of the holding body and a flange of the lid is formed; the sleeve body and the cover flange, which at through the cover form the sealed sleeve body at least partially the tapered section of the Cartridge body flange.
  • At least one of the two Flanges assembled to form the cartridge body flange is tapering towards the outside.
  • the wedge gap effect can also be gas-tight Installation of the two flanges of the holding body and Lid can be used.
  • the flange of the cartridge body preferably extends at an acute angle to the longitudinal axis of the cartridge beyond its cover-side end.
  • the So flange is a kind of extension of the cartridge body wall; the lid is comparatively deep in the Sleeve body inserted; at the end of the cartridge body on the cover a proportionate one is formed deep conical tapered depression that of the (Ring) flange of the cartridge body is limited.
  • On such cartridge body makes a corresponding device-side configuration required, namely the closure bottom with one of the recess of the cartridge body corresponding at the end of the cover Projection is provided.
  • the advantage of the above Training of the cartridge body consists in the Creation of a relatively long wedge through the flange is formed.
  • the flange preferably runs in its tapered section at an angle of 5 ° to 20 °, preferably at an angle of 10 ° to Longitudinal axis of the cartridge body.
  • the flange should lead to the outside Space between the cartridge storage and the bottom of the breech close the cartridge body.
  • Each parallel this space or the flange in the direction of movement of cartridge storage or closure bottom runs, so the more parallel it is in the direction of the longitudinal axis the cartridge runs, the lower the inserted cartridge body and not completely closed Cartridge store still free Gap between the cartridge bearing and flange or flange and lock bottom.
  • the gap should be between the cartridge bearing and the closure bottom in the direction the longitudinal axis of the cartridge, since the Gap constant regardless of the shutter opening is.
  • it is for removing the Cartridge required after a shot from the cartridge store, that the cartridge storage is conical.
  • the Above angle information for the flange (and thus also for the orientation of the space) from 5 ° to 15 or 20 °, preferably 10 °, compromise between two claims.
  • a deflection may be provided.
  • an angled section at least tapered over part of this angled section is.
  • the flange of the cartridge body is outgoing from the end of the cartridge body on the cover side put up.
  • the angled section runs in one acute angle of preferably 10 ° to 30 ° to the longitudinal axis of the cartridge body. Because of the redirection the plastic material, which is due to the high gas pressures wants to extrude, presented a "flow resistance".
  • the redirection could possibly vary Design alone prevent material extrusion; but it is better, as with this configuration provided the invention, following the deflection due to the tapered flange section, a wedge gap effect to evoke any material extrusion prevented.
  • the cover and the sleeve body are preferably together lockable, the locking particularly between the flanges of the lid and the sleeve body.
  • thermoplastic materials because of their material peculiarities Ignition charges not in any formability Bring (strength / path). Because of the described here Properties of thermoplastic materials in particular is the use of plastic cartridges instead of metal cartridges for those for metal cartridges designed bolt guns or central firearms not easily possible.
  • a plastic cartridge body is therefore advantageous, the one-sided open sleeve body to hold a propellant charge and an ignition charge to ignite the propellant charge at the Ignition charge acting pressure and a Lid for closing the open end of the sleeve body has, in which of the sleeve body and cover limited space an ignition pin coupled to the cover made of plastic longitudinally displaceable is arranged and the firing pin when exercising a pressure on the lid in the area of its coupling is movable with the firing pin and for lighting of the primer acts on it (mechanically).
  • the Ignition pin is movable in its axial direction coupled with the lid, the coupling either in the actual lid area through which the Sleeve body is closed, and / or in the flange area of the lid is given.
  • the formation of the coupling allows the cartridge body to also after the firing pin is loaded by the Firing pin of the shooting device is still gas-tight. The gas tightness can also be carried out by the device Measures are guaranteed, which will be discussed below becomes.
  • the cartridge body is provided with a firing pin, the one acting on the cartridge (cover) Firing pin is moved forward and with its striking end acts on the primer to initiate it.
  • the firing pin energy is thus in kinetic energy implemented for the firing pin, which in turn this Energy by deformation of the primer on it passes on to ignite the primer.
  • the firing pin thus acts as a transmission element for transmitting the Firing pin energy on the primer.
  • a transfer the energy of the firing pin through the cartridge wall, i.e. through the rigid lid is not currently provided according to the invention; much more is the cartridge body with the firing pin energy element converting into kinetic energy, namely the Ignition pin, provided.
  • the damping of the firing pin energy through the plastic material is thereby opposite known plastic cartridges significantly reduced.
  • the plastic cartridge can therefore be used Help of the firing pin mechanism designed for metal cartridges trigger without making changes to the devices must be made.
  • the plastic cartridge can be extremely unfavorable Stresses on minor gas leaks come in the area of the firing pin of the shooting device; this occurs, for example, when the cartridge body or the cover by the firing pin is damaged as a result of the impact and gas escapes, that then further across the space between Firing pin and firing pin guide in the lock bottom of the shooting device escapes.

  • Another advantage of the plastic cartridge according to the invention is that the primer in relative large distance to the opening of the sleeve body or to Lid of the cartridge is arranged.
  • This has in particular Advantages when using bulk tools; because the clean compression of the preferred as a wet charge inserted primer pill is now given to the extent as the cartridge (cover and / or sleeve body) in the case of mass processing by spilling out during compression kindling material because of the large insertion depth the wet load is no longer or hardly contaminated.
