FOLDING GUARD RAIL METHOD AND APPARATUS |
摘要 |
The present invention is for a safety guard rail system having folding guard rails designed to be raised or lowered at their base by a single individual from an acceptable safe distance from the edge of a precipice, such as the edge of a building roof. A sliding sleeve hinge lock locks each folding rail in an erect position and can be remotely unlocked for folding the rail. An elongated grappling tool has a hook-like end for grabbing the sliding sleeve hinge lock handle for locking and unlocking the hinge lock from a distance when erecting or folding a guard rail. |
