Definitions
- the invention relates to a cartridge ammunition which is magazineable for firing from an automatic firearm in a belt, and which comprises a cartridge case with a sleeve bottom, the rear side has a sleeve edge, which for removing the cartridge from the belt of claw-shaped Auszieherbacken a cartridge extractor automatic weapon can be grasped from the front.
- Such a cartridge ammunition is described for example in unpublished patent application 10 2008 034 660.8.
- This ammunition is an ammunition of caliber 40 mm which can be fired from an automatic grenade launcher of high fire speed.
- it is proposed to adapt the contour of the sleeve edge better to the Auszieherbacken.
- the invention has for its object to provide a cartridge ammunition of the type mentioned above, in which damage to the sleeve edge when removing the cartridge from a belt through the Auszieherbacken a firearm is easily avoided.
- the invention is based essentially on the idea to adapt the contour of the sleeve edge of the cartridge case to the edge of the sleeve facing the contour of the Auszieherbacken the cartridge extractor of the weapon from which the cartridge ammunition is to be fired.
- the force is applied when removing the cartridge from the belt distributed by a small plasticization on a larger area of the front side of the sleeve edge and avoids excessive local plastic deformation of the sleeve edge by the sharp Auszieherbacken.
- the ammunition according to the invention can be produced in a simple manner, since only the contour of the sleeve edge of the corresponding cartridge ammunition has to be changed slightly compared with known sleeve edge contours. This can be realized in a simple and cost-effective manner with today's customary production methods (CNC control). In addition, similar to the patent application mentioned above, also in this case, only a change of the cartridge and not the firearm (for example, the Auszieherbacken) required.
- the cartridge ammunition in the front region of the sleeve edge on a convex contour which is selected such that upon withdrawal of the cartridge from the belt, the facing surfaces of the Auszieherbacken and the front region of the sleeve edge come into contact on the spherical surface and not at the sharp corner of the extractor jaws.
- FIGS. 1 and Fig. 2 illustrated embodiment.
- Fig. 1 shows the sleeve bottom 1 of a cartridge case 2 for cartridge ammunition, which is magazineable for firing from an automatic firearm in a belt (not shown).
- the sleeve bottom 1 of the cartridge case 2 has the rear side a sleeve edge 3 with a Auszieherrille 4 arranged in front of it and has a threaded bore 5 for receiving an ignition device, not shown.
- the sleeve edge 3 on the front side is flat (ie substantially parallel to the trailing edge 7 of the cartridge case 2) formed in known cartridge ammunition, as this is indicated in the figure by the dotted lines 8.
- the front side 6 of the sleeve edge 3 is not flat, but convex, such that when the cartridge is pulled out of the belt, the mutually facing surfaces of the removal jaws and the front side 6 of the sleeve edge 3 come into contact with the crowned surface 10 and not at the corner 11 of the extractor jaws (Fig. 2).
- the invention is of course not limited to the embodiment described above, for example, the convex contour of the front side 6 of the sleeve edge 3 not only in borderless sleeves (cartridges, where -wie in the figure shown, the sleeve edge has the same outer diameter as the actual cartridge case) are used, but also in edge sleeves (cartridges in which the sleeve edge projects radially beyond the cartridge case).
