Abstract
Abstract Total barrier or guard-roll assembly comprises series of individual guard-roll barrier units spaced along one or both sides of a roadway. Each unit comprises support and guard structure rotatable about generally upright axis with upper portion closer to roadway axis to form overhang. When vehicle strikes one or more units they start rotating, attenuate impact, and redirect the vehicle. The overhand effect prevents climbing and keeps vehicle on ground. Impact surfaces are pneumatic lowpressure rubber tubes arranged to form frustocones rotating on vehicle spindle. They may also be of uniform diameter or may be single resilient conical bodies but are preferably series of heavy rubber tubes of variable diameter arranged to provide maximum surface to impacting vehicle. The attitude of the spindle may vary from vertical to permit use of uniform buffer elements. Barrier elements may be arranged in tandem parallel to the road shoulder to intercept errant vehicles and promote straight line attenuation. For positive arrest, elements are deployed in leadin lines in paired sequences to promote pocketing. Lateral spacing between paired elements converge to attenuate by actuating wringer effect. Special pocketing arrangements may be used to trap and decelerate trucks at critical locations.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
159 words
A highway safety guide-roll barrier unit adapted to be substantially vertically mounted in an automobile traffic area comprising: a spindle; at least one roller having an internal convex rim for rotatably mounting on said spindle; a two-section hub rotatably mounted on said spindle with the sections mating to form a total concave outer surface or circular groove into which said convex rim nests; said unit being assembled by placing a first or lower hub section on said spindle with its mating surface uppermost, placing said roller over said spindle with its convex hub nesting in the concave half surface of said first hub section, and placing a second or upper huB section on said spindle with its mating surface mating with the mating surface of said first hub section so that the convex section of said roller hub nests in the total concave surface of said hub with the second or upper hub section locking the roller in place.

Claim 3
Dependent Claim
61 words
The guide-roll barrier unit of claim 1 in which the outer ends of said hub sections are flat and there is a beveled area between them and the grooved area, each of said flat ends adapted to mate with the flat end of an adjacent hub section when a plurality of rollers are mounted on their corresponding hubs on said spindle.
Claim 4
Dependent Claim
167 words
A highway safety barrier comprising: a series of guard-roll units adapted to be mounted in longitudinally spaced relation adjacent to the margin of a roadway; each guard-roll unit including a support and a guard structure having a substantial vertical extent and being movably mounted on the support for rotation about a generally upright axis; said guard-roll unit being so constructed and arranged that the upper portion of the rotatable guard structure extends laterally closer to the axis of the roadway than does the lower portion thereof to exert a downward restraining force on a contacting vehicle, said barrier including a series of guide-roll barrier units along each side of a roadway to define an escape chute for runaway vehicles; the lateral spacing between opposing guide-roll barrier units of the two series being selected to provide for contact of both series simultaneously by the sides of a runaway vehicle; said units being laterally yieldable to permit entry and longitudinal movement of the vehicle while applying decelerating force thereto.
Claim 5
Dependent Claim
167 words
A highway safety barrier comprising: a series of guard-roll units adapted to be mounted in longitudinally spaced relation adjacent to the margin of a roadway; each guard-roll unit including a support and a guard structure having a substantial vertical extent and being movably mounted on the support for rotation about a generally upright axis; said guard-roll unit being so constructed and arranged that the upper portion of the rotatable guard structure extends laterally closer to the axis of the roadway than does the lower portion thereof to exert a downward restraining force on a contacting vehicle, said barrier including a series of guide-roll barrier units along each side of a roadway to define an escape chute for runaway vehicles; the lateral spacing between opposing guide-roll barrier units of the two series being selected to provide for contact of both series simultaneously by the sides of a runaway vehicle; said units being laterally yieldable to permit entry and longitudinal movement of the vehicle while applying decelerating force thereto.
Claim 6
