Patent ID: 7878184

Claim:
A hardball weapon with electrically activated firing of a bullet, including a weapon housing with pistol grip and trigger at its bottom side, a barrel for firing the bullet at the front, a cartridge magazine that may be mounted on the casing, and a reciprocating firing mechanism arranged in the weapon housing, the functional elements of the firing mechanism mounted directly in the weapon housing, where the firing mechanism is driven by an electric motor disposed in the pistol grip via a gear wheel arrangement and includes a piston means that may produce an air pressure for firing a bullet through the barrel, characterised in that the firing mechanism includes a first outer piston means that functions as a movable bolt in the weapon for moving a cartridge from the cartridge magazine into a cartridge chamber in the barrel and to extract the cartridge from cartridge chamber after firing, and a second piston means which is provided displaceably inside the first piston means and coaxially in relation thereto and airtightly fitting to the inner wall of the first piston means, where at its end facing the cartridge chamber the first piston means has an aperture for discharging pressurised air into. an adjacent end of a cartridge; where both piston means are seated inside the weapon housing and guided by longitudinal guides extending inside and/or along the piston means and initiating from a plug which is fastened at the end of the weapon housing facing away from the barrel; where a central guide is provided concentrically with and inside the second piston means, extending out from the plug; and where between the free end of the central guide and an inner end wall of the second piston means there is provided a compression spring, as the gear wheel arrangement includes a double gear wheel with a first set of teeth and a second set of teeth, the sets of teeth corresponding to and engaging respective parallel first and second toothed racks provided on first and second piston means, respectively, where rows of teeth of the first set of teeth and the second set of teeth are discontinuous and without any teeth at segments of the circumference of the double gear wheel, so that there is free travel between the two segments without teeth and the teeth of the toothed racks, and that the two segments without teeth are partly overlapping segments of a circle on the double gear wheel; and that the segments without teeth on first and second sets of teeth, respectively, during the rotation of the double gear wheel in its normal direction of rotation are mutually arranged so that the toothed rack of the first piston means is released from engaging the first set of teeth before the toothed rack of the second piston means is released from engaging the second set of teeth.
