Abstract
A toy for launching two or more projectiles employing a central shaft cocking mechanism for rapid fire projectile launching through quick, simple and fun cocking and triggering mechanisms. The toy includes a housing assembly, a projectile device disposed about the housing with two or more projectiles, a piston and cylinder assembly. The piston is secured to the housing in a fixed position and the cylinder is slidably mounted on the piston, a cocking mechanism in mechanical communication with the piston and cylinder assembly including a shaft extending through the projectile device for engagement with the cylinder capable of moving the cylinder to a cocked position. A trigger mechanism is secured to the housing capable of advancing the projectile device to a firing position and capable of releasing the cylinder from a cocked position to advance the cylinder on the fixed piston and discharge a burst of compressed air launching a projectile.
