Patent ID: 7722282

Claim:
A crash barrier assembly, comprising: a plurality of prismatic, solid material structural elements, at least one of said elements having a shoulder forming two vertical surfaces and a horizontal surface on at least one of its sides, and another element having substantially matching surfaces on at least one of its sides so as to facilitate juxtaposing of said elements, with a gap at least between juxtaposed vertical surfaces, a coupling structure in the form of a hole or bore and a rod at least partially located in said hole or bore with a clearance traversing said horizontal surface and interconnecting said elements to each other in a manner facilitating relative controlled movement along the horizontal surface of one element with respect to the other about said coupling structure, and energy-absorbing material, different than said solid material, located in said hole or bore in at least one of said elements and surrounding at least a portion of said rod, whereby, upon impact, the relative movement between two adjacent elements about said rod, is attenuated by energy absorbed by the energy-absorbing material.
