A ball tossing apparatus includes a support frame and a plurality of launch devices fixed to the support frame and arranged in a two-dimensional array. The launch devices include cylinders having a spring fixed therein, with a ball carrier fixed to the spring. The balls are retained in a loaded position (springs compressed) and then upon activation of the launch devices are launched vertically into the air to the sports player. In another embodiment, the launch devices include a rotating lever which is acted on by a biasing member to launch the ball vertically from the cylinder. A method for launching the balls includes the steps of loading the balls into a two dimensional array, and then launching the balls according to a launch sequence. An electronic control system for use with the ball tossing apparatus includes a launch module for launching the loaded balls in the plurality of launch devices according to a launch sequence. The launch sequences can be randomly generated, programmed by the sports player, or retrieved from memory. The launch of the balls can also be controlled remotely.

Projectile launchers have an elongated cylindrical body defining a projectile bore having a bore axis, the body having an open forward exit end, the body having a gas inlet facility at an opposed rear end, a movable latch element connected to the body and having a latch portion movable between a retention position in which the latch portion protrudes into the bore and a release position, and the latch element being biased to the retention position such that a projectile in the bore rearward of the latch is retained by the latch portion except until a gas pressure above a selected amount builds up behind the projectile to overcome the biasing of the latch and launch the projectile. The latch element may be clear of the bore when in the release position.

A differential pressure type inflating device, adapted for fast inflating the devices that need inflating, comprises a gas container, a relief valve, a gas nozzle, a pipe joint, a switchvalve, and a relief pipe. When external high pressure gas enters the gas container and renders the gas pressures in the gas container and the relief pipe reaching a balance condition, the switchvalve can be pressed to generate pressure drop in the relief pipe, which launches the relief valve and discharges the high pressure gas in the gas container from the gas nozzle. In this design, the gas container, relief valve, gas nozzle, relief pipe, and pipe joint are connected with screwing structures, so as to achieve the function of easy assembling.

A variable velocity pneumatic launcher including at least one chamber filled with a projectile. The launcher includes a ballast chamber filled with pressurized air selectively released to propel a projectile from the launcher's barrel. The launcher includes a firing chamber filled with ambient air and a ballast chamber filled with pressurized air. A piston rod extends between the chambers and attaches to a firing piston and a ballast piston located inside the firing chamber and ballast chamber, respectively. The rod is connected to an adjustable velocity valve which controls the amount of longitudinal movement of the rod. When the trigger is activated, a portion of the pressurized air from the ballast chamber is delivered to the firing chamber. Because the surface area of the firing piston is greater than the ballast piston's surface area, the force exerted on the firing piston is sufficient to shift or displace the ballast piston and allow pressurize air to be released into the upper chamber containing the projectile.

A compressed gas gun comprising a chassis, a pellet firing assembly including a breech and a slidable bolt mounted in the chassis, a valve assembly mounted in the chassis, a barrel assembly comprising a barrel, a grip for holding the gun, a trigger assembly comprising a trigger, and a magazine receiver for holding a removable magazine for storing pellets.

A gas gun launcher has a pump tube and a launch tube with a first end of the launch tube slidably inserted into a second end of the pump tube. The pump tube may hold a heat exchanger to heat a light gas used to launch a vehicle. A sliding seal can be employed to manage recoil and to retain the gas within the launch tube and the pump tube. A fast-closing muffler at the second end of the launch tube can conserve the light gas utilized for launching a vehicle, enabling the light gas to be recycled. A launch tube alignment system is preferably automatic, ensuring the survival of the launch vehicle.
