  • High-rise fire fighting and rescue system
    Patent number: 4865155
    Abstract: An external elevator system piggy backs a first rail car on a second rail car to permit simple and rapid transfer of the first rail car to an upper setback section of a high-rise building. Each rail car is equipped with pinion drives that engage racks fixed to vertical rails that are attached to the faces of the base section and setback section of the buildings. The cars also have motor driven wheels that allow the car to drive on horizontal surfaces.

  • Deployable rail structure for high-rise building evacuation system
    Patent number: 4830141
    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.
