Patent ID: 8061276

Claim:
A projectile for use in a non-lethal weapon system, the projectile comprising: (a) a first body and a second body with a longitudinal axis, wherein the projectile is configured to be launched substantially along said longitudinal axis towards a target; and (b) an elastic mechanism disposed between said first and second bodies, wherein upon impact of the projectile with said target, said elastic mechanism is adapted to absorb elastically a first portion of the kinetic energy of the projectile; (c) a locking mechanism which stores said first portion of said kinetic energy within said elastic mechanism, wherein said second body includes a hollow, wherein a portion of said first body fits marginally within said hollow; wherein said first body is externally ridged with a plurality of first ridges and said hollow is internally ridged with a matching plurality of second ridges, and while said first body is forced into said hollow during said impact, said locking mechanism is adapted to lock said first ridges on said second ridges, wherein said first ridges and second ridges are shaped to prevent release of said elastic mechanism.
