Abstract
Fire escape apparatus for egress from a multi-storied building structure from an upper level thereof is provided. The apparatus includes an elongate mesh tube, the tube being substantially longer than the structure height from which escape is required, and sufficiently long to enable extension of the tube downwardly to the ground. The building structure has permanently attached thereto a guide wire or cable extending at a desired angle from the upper level to the ground. The elongate mesh tube has affixed thereto, at spaced-apart intervals along its length, a plurality of supporting blocks-and-pulleys engaging the guide wire or cable. When escape is required, the mesh tube is deployed from the upper level to the ground, riding upon the pulleys, thereby permitting escape to ground level through the tube by persons entering the tube from the upper level.
