ABSTRACT:
A fire escape device that enables parents to lower their children (as well as pets and possessions) to the safety of the ground from elevated windows or terraces of tall structures. The load-lowering device is a hard-shell vessel cradled in a fire-resistant sling that is attached to a load-carrying harness. A variable-length tether is attached to the harness for lowering the assembly. A descent control fixture, a cleat only, is affixed beneath each window and to each terrace rail in the dwelling, and this gives the occupants a plurality of stations at which to deploy the fire escape device in case of emergency. After loading the device with children, pets and/or possessions, the device allows its contents to be secured lowered in a manually-controlled descent to the ground.
