Abstract
A rocket launcher (10) is provided having a manual air pump (11) coupled to a base unit (12) through an elongated pressure tube (13) having a pressure release valve or trigger (20). The base unit has a pressure chamber (24), a launch tube (25), and an orientation sensitive safety mechanism (32) coupled to the end of the pressure tube. The safety mechanism is coupled to an internal pressure tube (33) which extends to a pressure sensitive release valve (34) that controls the release of pressurized air from the launch tube. The orientation sensitive safety mechanism prevents the launching of projectiles should the launch tube be offset from a vertical orientation and depressurizes the launcher should an operator attempt to fire the launcher while in an offset orientation.
