Portable electric driven compressed air gun

Abstract

A portable electric motor driven air gun powered by a power source. The motor is coupled to a lead screw, which drives a piston. The piston compresses air in a chamber producing high-pressure air. When sufficient energy is stored within the air stream by the piston a valve opens which releases the air to act on the projectile. The compressed air is used to push a projectile such as a paintball, an airsoft ball, a ''bb'', or a pellet through a barrel. The lead screw is then reversed and the piston is reset for the next shot. The piston is preferably coupled to a feeding mechanism to facilitate positioning of the projectile for firing. The direction speed and operative modes of the gun are preferably controlled with an electric circuit. The power source is preferably rechargeable and allows the air gun to be operated completely independent from either a wall outlet or a compressed air supply.

Description

technical field [0001] The present invention relates to air guns, air rifles, shotgun rifles, paintball guns and the like. Such air-operated guns are typically powered by a hand-fired spring, compressed gas, or a hand-operated pump. The disadvantages of these guns are outlined in more detail below. Background technique [0002] Air rifles have been around for years and have seen multiple developments over the past few years. The most common methods used to propel a projectile use energy from compressed gas or from a spring. For variations based on this teaching, there are four main techniques represented in the prior art for launching projectiles, these techniques include: (i) the use of stored compressed gas in the form of carbon dioxide cylinders or other high pressure storage tanks; (ii) use a strong spring to push a piston that compresses air, which then pushes the projectile; (iii) use a hand pump to pressurize the air for later release; and (iv) use a direct valve s...

AI Technical Summary

Problems solved by technology

[0008] 1. Difficult to operate

Pulling the bolt or pumping an air rifle can be a time consuming and physical affair

[0009] 2. Cannot move quickly between single shot, semi-automatic, burst or automatic modes

Cannot support rapid fire operations required by the above

[0010] 3. Significant inconvenience in refilling transport and use of high pressure gas cylinders

[0012] 5. Double recoil effect

[0013] 6. Complex mechanisms and vent schemes leading to potentially expensive production costs and reliability issues

[0014] 7. Inefficient use / or coupling of compressed air to projectiles resulting in low energy projectiles and large energy input requirements
