    • A line throwing device adapted to be launched from a riot gun or similar tubular launching device comprises an elongated projectile that fits in the tubular launching device, a fin assembly slidably mounted on the body of the projectile such that the fin assembly slides forwardly to permit the rear end of the projectile to be positioned in the launching device for launching and slides rearwardly to a flight stabilizing position at the rear of the projectile as the projectile is launched from the tubular launching device. A rocket engine is mounted in the rear of the projectile for propelling the projectile. An ignition mechanism comprising a conventional shotgun primer cap mounted in a plastic casing fits on the end of the rocket and is ignited by the trigger and firing pin of the gun. A line is coiled in a canister removably attached to the gun, with one end of the line being attached to a harness mounted on the projectile so that the line can be carried to the desired target.
    • 适于从防暴枪或类似的管状发射装置发射的线投掷装置包括装配在管状发射装置中的细长抛射体,可滑动地安装在射弹体上的鳍组件,使得鳍组件向前滑动以允许 射弹的后端定位在发射装置中,用于发射,并且当从管状发射装置发射抛射物时,向后滑动到射弹后部的飞行稳定位置。 火箭发动机安装在射弹的后部,用于推动射弹。 包括安装在塑料壳体中的常规猎枪底漆帽的点火机构装配在火箭的端部上,并被枪的触发器和击发销点燃。 一条线卷绕在可移除地附接到枪的罐中,线的一端附接到安装在射弹上的线束,使得线可以被携带到期望的目标。
