Patent ID: 8622650

Claim:
A multi-purpose rotational barrier unit comprising: a barrier unit adapted to function within a land-based or water-based environment having three equally sized and configured rigid walls interconnected to form two side walls and one bottom wall thus forming a generally triangular shape having a first top edge and two side edges, each said wall containing a plurality of longitudinally segmented surfaces which are constructed and arranged to maintain said barrier unit in a stable upright position or to dissipate side impact loads in an upward direction to lessen translational forces impacting said barrier unit thereby reducing the tendency of said barrier unit to roll over; each said wall defined by a first segmented surface and a second, opposing segmented surface wherein said segmented surfaces form a generally planar surface to maintain said barrier unit in a stable, upright position when placed on a land or water surface thereby forming said wall, and a plurality of diverging segmented surfaces between said first and second segmented surfaces which intersect to form a gap between said first and second segmented surfaces when said barrier is placed on the land or water surface; two opposing end walls connected to said equally sized and configured walls thus forming an interior; said opposing end walls containing one or more rotation members for providing rotational movement around at least one axis along said longitudinal axis of said at least one opposing end wall when connected on one or both ends with an adjacent barrier unit, said rotation members constructed and arranged to provide said barrier unit rotational movement along said longitudinal axis of said barrier unit which is independent from said movement of said adjacent barrier units; whereby rotation of said barrier about said axis point results in said barrier maintaining its structural configuration in an upright position and maintaining the same configuration as said adjacent barrier.
