Abstract
Individual rail segments of a deployable exterior elevator rail structure are stored horizontally on each floor of a high-rise building. When actuated from a ground level control panel, closure panels swing aside to provide access openings through which linear actuators translate and rotate the rail segments to a vertical deployed position. Motor driven threaded bolts automatically secure the ends of adjacent rail segments together, and the linear actuators rigidly brace the deployed rail structure in front of the face of the building.
