ABSTRACT:
This disclosure concerns an automatic handrail for a platform lift which automatic handrail is pivoted along one side of the foldable platform along an axis perpendicular to that of the hinge of the platform for oscillating movement from an inoperative position parallel to the plane of the platform when the platform is in its vertical inoperative position, into a vertical operative position in a plane orthogonal to the plane of the platform when the platform is in its horizontal operative position. This movement of the handrail is affected by an oscillating cam arm anchored to the pivotal connection of the reciprocating motor for oscillating the platform, which cam arm engages a cam plate mounted on the side of the pivoted handrail. The handrail is normally urged into its inoperative position parallel to the plane of the platform by a resilient means. A stop may be provided for limiting the movement of the handrail into its vertical operative position.
