Definitions
- the invention relates to an intermediate means between cargo and shot in one Shotgun shell.
- the Cupplugs are usually made of plastic, such as LDPE (Low Density Polyethylene) or comparable materials.
- the Sealing discs can be made of other materials instead of plastic consist, for example, cardboard, felt, fibers or combinations the same. Such materials can lead to sealing problems and thus Disturbances of the internal ballistics, the shot development in the course, the ignition and Combustion processes, lead.
- a shotgun cartridge case which is a Intermediate means, which is composed of several parts together. Also Here preferred materials are non-biodegradable plastics as well Rubber.
- the object of the invention is to make the intermediate means so that they No longer burden the environment and at the same time improve the internal ballistics.
- the intermediate means, the Sealing disk according to the invention and the cup plug according to the invention are made of biodegradable, non-brittle materials, which are the Temperature load of the propellant gases without affecting the function Destruction tolerated and when stored under Kompostier discipline are completely biodegradable and also a shaping get an optimal seal against the hot gases of the Cause propellant charge.
- the biodegradable materials of the intermediate means such as the Plastic BAK from the company BAYER, advantageously allow degradation in nature by rotting in an appropriate time. When used on shooting ranges Disposal with household waste or composting possible.
- Plastic For example, biologically harmless fibers such as natural fibers, Carbon fibers, Glasfasem or Mineralfasem be reinforced.
- the structural design of the cup-shaped plug according to the invention with reinforced Slats allow optimal drive and clean guidance of the Shotgun blast.
- the damping part is designed so that a uniform Power transmission of the gas pressure on the shotgun and thus on the shotgun is guaranteed.
- the new design as well as the new materials of the interim means effect advantageous a uniform distribution of the shot shave.
- FIG. 1 shows a sealing disk 1 of the H-shape according to the invention from FIG biodegradable plastic.
- the outer diameter 2 and the diameter 3 of the reinforced central part 4 and the thickness 5 of the disc are so on each other Tuned that the forces of gas pressure over the entire disc surface evenly distributed on the shot load.
- the good seal of the disc 1 opposite to the sleeve wall is characterized by which the angle 6 to a thickness of reaches about 0.4 to 0.5 mm tapered two-sided webs 7, which thereby characterized as act on the sleeve wall clinging sealing lips.
- the angle 6 is about between 15 and 20 degrees.
- the middle part 4 tapers at the same angle 6.
- the thickness 5 of the disc is 3 mm and the Diameter 3 of the middle part 4 at its end face 7 mm. Because of that Sealing disk 1 is symmetrically shaped, it is not necessary to install under a certain direction, which facilitates the assembly of the cartridges.
- FIG. 2 shows a cup plug 10 according to the invention in longitudinal section.
- the Diameter 11 is tuned to the caliber and the total height 12, in present embodiment 40 mm, is divided into the height 13 of the basket 14th for the shot, here 23 mm, the height 15 of the damping part 16, here 9.5 mm, and the Height 17 of the cup-shaped sealing member 18, here 7.5 mm, the annular wall clings to the sleeve.
- the damping member 16 consists of two parallel arranged, thin-walled V-shaped webs 19, the ridge edges 20 itself opposite, as shown in Figure 3 can be seen.
- the basket 14 has on its periphery evenly distributes four up to the basket bottom reaching slots 21, the in Direction of the central axis 22 run.
- the individual wall segments act like resilient lamellae, which release the shotshell when exiting the projectile facilitate. Again, the shape of the intermediate means allows a uniform transfer of gas pressure to the shotshell and optimal Seal to the barrel.
