Non-lethal pistol and method of using same
View Patent ↗A non-lethal pistol for propelling projectiles, such as paintballs. The pistol has a body with a grip portion and a barrel. A canister of propellant received in the body to supply a valve assembly with propellant that is selectively vented to propel projectiles through the barrel. The pistol includes a firing mechanism adapted to actuate the valve assembly.
1. A method of launching a projectile from a non-lethal pistol, the method comprising the steps of:
providing a non-lethal pistol with a valve assembly configured to vent gas to propel projectiles out of a barrel;
inserting an unused canister of compressed gas into the non-lethal pistol;
making an initial trigger pull of a trigger on the non-lethal pistol to release a supply of compressed gas from the unused canister to the valve assembly, wherein the valve assembly does not include a supply of compressed gas to vent responsive to the initial trigger pull; and
making a subsequent trigger pull on the non-lethal pistol to vent compressed gas supplied to the valve assembly responsive to the initial trigger pull to propel a projectile from the non-lethal pistol;
wherein the initial trigger pull moves a piercing pin to pierce a seal covering a mouth of the canister; and
wherein a cam surface of the trigger moves the piercing pin toward the canister of compressed gas during at least the initial trigger pull.
2. The method of claim 1 , wherein the initial trigger pull pierces the unused canister of compressed gas, but does not fire a projectile.
3. A method of launching a projectile from a non-lethal pistol, the method comprising the steps of:
gripping a non-lethal pistol with a valve assembly configured to vent gas to propel projectiles out of a barrel;
inserting an unused canister of compressed gas into the non-lethal pistol;
piercing a seal covering a mouth of the canister with a piercing pin by making an initial trigger pull on the non-lethal pistol, wherein the initial trigger pull does not propel a projectile out of the barrel;
making a subsequent trigger pull on the non-lethal pistol to vent compressed gas supplied to the valve assembly responsive to the initial trigger pull to propel a projectile out of the barrel; and
wherein a cam surface of the trigger moves the piercing pin toward the canister of compressed gas during at least the initial trigger pull.
4. A method of launching a projectile from a non-lethal pistol, the method comprising the steps of:
gripping a non-lethal pistol with a valve assembly configured to vent gas to propel projectiles out of a barrel;
inserting an unused canister of compressed gas into the non-lethal pistol;
making at least two trigger pulls on the non-lethal pistol to propel a projectile after inserting the unused canister;
wherein an initial trigger pull after inserting the unused canister pierces a seal covering a mouth of the canister with a piercing pin to supply compressed gas to the valve assembly, but does not propel a projectile out of the barrel;
wherein trigger pulls subsequent the initial trigger vent compressed gas supplied to the valve assembly responsive to the initial trigger pull to propel projectiles out of the barrel; and
wherein a cam surface of the trigger moves the piercing pin toward the canister of compressed gas during at least the initial trigger pull.
5. The method of claim 4 , wherein a cam surface of the trigger moves a piercing pin toward the canister of compressed gas during at least the initial trigger pull to pierce the seal.
