Appeal No. 2000-0523
Application 08/583,307
THE INVENTION
The invention relates to a roadway guardrail barrier
having
an effective depth or capture area intended to
receive the moving vehicle in a recessed portion of
the guardrail barrier bounded by upper and lower
curved portions projecting toward the roadway to
stabilize the vehicle and reduce the tendency for
the vehicle to vault over or dive under the barrier
or to roll when redirected by holding the vehicle
against upward and downward motion [specification,
page 1].
Claim 1 is illustrative and reads as follows:
1. A guardrail barrier that balances moment of inertia
and membrane effect without requiring more material to reduce
the tendency of high center of mass vehicles from turning over
comprising:
outer curves;
a central portion between said outer curves;
the central portion and outer curves being positioned to
provide an effective depth of between 9 to 15 inches.
