Ring airfoil style paintball and launcher

Abstract

A ring airfoil style paintball comprises a ring airfoil carrying a marking agent. The marking agent is located in one more compartments of a body of the ring airfoil. In one embodiment, marking agent is located in an annular ring in a nose section of the body, or in a plurality of spherical compartments in the nose section of the body. In one embodiment, the ring airfoil style paintball is connected to a sabot when launched. Cartridges comprising a sabot containing the ring airfoil style paintball are launched from a launcher. In one embodiment, the cartridges are launched with a compressed air charged. The launcher includes a magazine for sequentially delivering cartridges for launch. A stripper associated with the launcher strips the sabot from the ring airfoil paintball, and an ejector ejects the stripped sabot from the launcher.

Description

RELATED APPLICATION [0001] This application claims priority to U.S. Provisional patent application Ser. No. ______, filed Jan. 9, 2003.FIELD OF THE INVENTION [0002] The present invention relates to a projectile for delivering a marking agent. BACKGROUND OF THE INVENTION [0003] The sport of paintball has experienced tremendous growth. In this sport, targets (generally opposing players) are marked with paint delivered by a “paintball.” The present state of the art paintball is a three gram hollow spherical projectile, usually made of gelatin, and filled with a glycol based pigment. These paintballs are launched from compressed air or carbon dioxide powered devices at velocities not exceeding three hundred feet per second. [0004] The present invention is directed at overcoming two major limitations of present, state of the art paintballs: short range and poor accuracy. These factors have limited the distance at which a paintball can be effectively launched. Thus, one desiring to mark a...

AI Technical Summary

Benefits of technology

[0011] In one embodiment, the cartridges are launched with a compressed air charged. The launcher includes a trigger which releases a compressed air charged behind a loaded cartridge. The cartridge is then propelled through a barrel. A sabot stripper is located at the end of the barrel. The sabot stripper strips the sabot from the ring airfoil style paintball, allowing the ring airfoil style paintball to travel towards the intended target. Preferably, the stripped sabot is ejected from the launcher, clearing the path for the next cartridge.

[0013] Preferably, a barrel of the launcher is rifled for imparting a spin to the sabot. This spin is, in turn, imparted to the ring airfoil style paintball, giving it gyroscopic stability during flight.

[0015] The ring airfoil style paintball of the invention has numerous benefits and advantages. Among others, the ring airfoil style paintball has a true flight path and travels farther than standard spherical paintballs when the same launch energy is imparted. This allows the ring airfoil paintball to be used in long-distance targeting. In addition, the lower launch energy and larger impact surface area greatly reduces the probability of injury associated with impact of the paintball at the target.

Problems solved by technology

These factors have limited the distance at which a paintball can be effectively launched.

Thus, one desiring to mark an object must close to within the projectiles relatively short range, which is sometimes not possible and is always inconvenient.

Several problems contribute to the short range and poor accuracy of the paintball.

First, the short range is due in part to the limitation upon the maximum velocity of the paintball.

Accuracy problems result from a number of factors.

Paintballs may not be symmetrical and may not have a center of mass which coincides with the center of the ball.

Both of these factors cause the paintball to spin, causing it to curve from a straight trajectory.
