  • Patent number: 6375586
    Abstract: Devices increase an arrow's kinetic energy, and hence the force on target impact, without a substantial decrease in the velocity of the arrow as compared to the same arrow without such devices. In especially preferred forms, the impact-enhancing devices are insertable into an arrow shaft and include an impact-enhancer weight which is freely moveable within the arrow shaft. The impact-enhancer weight will thus be propelled in response to rapid deceleration of the arrow (i.e., caused by the arrow head striking a target area). The relatively high velocity movement of the impact-enhancer weight will create a secondary kinetic energy effect which drives the arrow head further into the target area. That is, the impact-enhancer weight will be propelled forwardly at a sufficiently high velocity and strike a rearward region adjacent the arrow head thereby generating a secondary impact force (i.e.
