Abstract
A shark gun injects a sharpened projectile into a predator and thereafter forces compressed gas into the predator. The shark gun is comprised of a compressed gas holding cylinder, a firing chamber having a plunger that bears the sharpened projectile and a valve that selectively permits the compressed gas to act on the plunger. A trigger actuates the valve.
Claims20
A shark gun comprising:
- a housing
- a cylinder, attached to the housing, for holding compressed gas therein;
- a firing chamber, having a hollow interior and having a first end, a solid second end with a first opening, and a first medial portion, attached to the housing;
- a detent, encompassing the hollow interior within the first medial portion;
- a plunger, having a base with a pair of annular rings and at least one second opening therebetween, a projectile with a sharpened end with at least one third opening and a first hollow passageway extending between the at least one second opening and the at least one third opening, the plunger adapted to slide within the firing chamber between a retracted position within the firing chamber and an extended position wherein the projectile extends from the first opening;
- a valve, operative between a closed position preventing gas flow communication between the cylinder and the firing chamber and an open position permitting gas flow communication between the cylinder and the firing chamber, disposed within the housing;
- and
- a trigger for articulating the valve between the closed position and the open position.
