Abstract
Abstract A striker cartridge for weapons using central firing cartridges especially for shotguns has a jacket in whose bottom a circular opening is provided in the impact area of the firing pin. An impact element is inserted into this opening from the inside of the jacket and is biased by a resilient spring oppositely to the impact direction of the firing pin. The opening for receiving the impact element is arranged excentrically to the jacket axis and the impact element is rotatably mounted in this opening so that after repeated striking of the firing pin against the impact element it is rotated to expose a new intact area to the firing pin.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
113 words
A striker cartridge for weapons with central firing cartridges, especially for shotguns, consisting of a jacket similar to a regular cartridge jacket and including a generally tubular side wall and a bottom wall, in whose bottom wall a circular opening is provided in the impact area of the weapon's firing pin and into which opening an impact element is inserted from the inside of the jacket and biased by a resilient spring oppositely to the impact direction of the firing pin, the improvement consisting in that the opening (5) for receiving the impact element (6) is arranged eccentrically to the jacket's longitudinal axis, and the impact element is rotatably mounted in this opening.
Claim 2
Dependent Claim
113 words
A striker cartridge for weapons with central firing cartridges, especially for shotguns, consisting of a jacket similar to a regular cartridge jacket and including a generally tubular side wall and a bottom wall, in whose bottom wall a circular opening is provided in the impact area of the weapon's firing pin and into which opening an impact element is inserted from the inside of the jacket and biased by a resilient spring oppositely to the impact direction of the firing pin, the improvement consisting in that the opening (5) for receiving the impact element (6) is arranged eccentrically to the jacket's longitudinal axis, and the impact element is rotatably mounted in this opening.
Claim 3
Dependent Claim
43 words
A striker cartridge according to claim 1, wherein the diameter of the opening (5) corresponds to approximately half the diameter of the jacket bottom wall, and the center of the impact element (6) is as remote as possible from the jacket's longitudinal axis.
Claim 4
Dependent Claim
58 words
A striker cartridge according to claim 2, wherein the impact element (6) has the form of a stepped disk with different diameters, the disk areas of smaller diameter having a thickness which corresponds to the wall thickness of the jacket bottom wall, (4), and a diameter which corresponds approximately to the opening (5) in the jacket bottom wall.
Claim 5
Dependent Claim
86 words
A striker cartridge according to claim 2, wherein the impact element (6a) has the form of a stepped disk comprising a central area of larger diameter and two adjacent outer areas of a smaller diameter, each area of smaller diameter having a thickness which corresponds to the wall thickness of the jacket bottom wall (4), and a diameter which corresponds approximately to the diameter of the opening (5) in the jacket bottom wall, said outer areas being on opposite sides of said larger diameter central area.
Claim 6
Dependent Claim
26 words
A striker cartridge according to claim 1, wherein the outer face of the impact element (6) has one or more slots (11) for rotating said element.
Claim 7
Dependent Claim
