Abstract A guard barrier system for along the edge of a vehicular roadway or the like consists of substantially solid, resilient, generally cylindrical bumper elements axially mounted on posts for rotation thereon. A plurality of the posts with bumper elements thereon are spaced along the edge of a roadway or the like and are fixed to the ground in generally vertical position. Adjacent posts with bumper elements thereon are connected together to form a continuous barrier system by one or more cables or rails carried on the posts and extending between adjacent posts.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
A guard barrier system comprising in combination a plurality of posts adapted to be spaced along a roadway or the like in generally vertical position with their lower ends fixed to the ground, a generally cylindrical, substantially solid, resilient bumper element mounted axially on each post for rotation thereon by the posts extending through longitudinal axial bores through the bumper elements, respectively, the bottom ends of said bumper elements resting on the ground to be in frictional engagement therewith for providing drag on rotation of the bumper elements, and a stringer element extending between each adjacent pair of posts supported on said posts said stringer element comprising one of a cable threaded through adjacent posts and a rail attached to successive posts, above the bumper elements thereon.
Claim 2
Dependent Claim
