Combination non-lethal projectile launcher and flash light
View Patent ↗An apparatus for firing a non-lethal projectile comprises a body with an internal cavity. A light source may be disposed in the cavity to illuminate an area outside the body. A firing mechanism may also be provided to cause a projectile to be propelled through the body.
1. An apparatus for firing a non-lethal projectile, said apparatus comprising:
a barrel;
a firing mechanism including a piston disposed in a chamber, wherein said piston is movable between a first position and a second position, and wherein said piston prevents fluid communication between said chamber and said barrel in said first position and said piston allows fluid communication between said chamber and said barrel in said second position;
an inlet valve movable between an open position that provides fluid communication between said chamber and a source of compressed gas and a closed position that prevents fluid communication between said chamber and the source of compressed gas;
a cam operatively connected between said piston and said inlet valve, wherein said piston engages said cam to close said inlet valve when said piston moves from said first position to said second position; and
wherein said inlet valve moves to said closed position responsive to movement of said piston from said first position to said second position.
2. The apparatus of claim 1 , wherein said piston is configured to move from said first position to said second position when a pressure within said chamber exceeds a predetermined pressure.
3. The apparatus of claim 1 , further comprising a spring urging said piston toward said first position.
4. The apparatus of claim 3 , wherein said spring has a spring force selected to maintain said piston in said first position until a pressure within said chamber reaches a predetermined pressure.
5. The apparatus of claim 1 , wherein said inlet valve is a Schrader valve.
6. The apparatus of claim 1 , further comprising a lever operatively connected between said cam and said inlet valve, wherein said lever moves in a first direction responsive to movement of said cam, and wherein said inlet valve moves to said closed position responsive to said lever moving in said first direction.
7. The apparatus of claim 6 , wherein movement of said lever in a second direction causes said inlet valve to move to said open position.
8. The apparatus of claim 7 , further comprising a trigger operatively connected to a link, wherein said link moves said lever in said second direction responsive to actuation of said trigger.
9. The apparatus of claim 6 , further comprising a pin operatively connected between said lever and said inlet valve, wherein said pin moves in a third direction responsive to movement of said lever in said first direction, and wherein said inlet valve moves to said closed position responsive to said pin moving in said third direction.
