Abstract
A hand carryable, non-lethal personal protection device using compressed gas for operation. In some embodiments the device uses the compressed gas to create and shoot a vortex of air at the target. In other embodiments, the compressed gas can be used to shoot a burst of atomized water at the attacker. In still other embodiments the device uses the compressed gas to shoot ammunition, such as a ring airfoil, O-ring, bean bag, or other non-lethal blunt trauma munitions at the target. In still further embodiments, the device is modular in its construction, and can be used to apply the compressed gas to various different attachments.
Claims14
A non-lethal weapon, comprising:
- a pressurized assembly including a pressure vessel, a first plug, and a second plug located at least in part within said pressure vessel and attached to said first plug;
- a handle attached to said pressurized assembly to permit the user to hold said pressurized assembly by the hand;
- said pressure vessel having a distal end with a first opening and a proximal end with a second opening and a first chamber therebetween adapted and configured to hold therein gas under pressure;
- said first plug having a forward end that slidingly couples to the second opening of the proximal end of said pressure vessel and an aft end adapted and configured to include a second chamber, said first plug being slidable relative to said pressure vessel between first and second positions;
- said second plug having a forward end that seals with the first opening of the distal end of said pressure vessel in the first position and an aft end that attaches to said first plug, said second plug including a passageway that provides fluid communication from the first chamber to the second chamber;
- and the weapon further comprising:
- a seal between the forward end of said first plug and the second opening of the proximal end of said pressure vessel;
- an axisymmetric nozzle receiving the released gas and expelling the gas to ambient conditions, said nozzle including a generally smooth surface having a distally located lip that protrudes into the expelled gas;
- wherein the application of gas pressure from the first chamber through the passageway to the second chamber pushes said first plug and said second plug to the second position relative to said pressure vessel, and in the second position the forward end of said second plug moves out of sealing with the first opening and permits the release of the pressurized gas from the first opening to flow over the smooth surface and lip.
