Abstract:

A building evacuation device is provided for lowering a load (e.g. a person or another object) from a multi-story building to the ground at a controlled rate. The device includes a cable that may be unwound from a spool to allow for the load to be lowered to the ground, where the spool is connected to a rate governor to control the rate at which the cable may unwind and, in turn, the rate at which the load will be lowered to the ground. The unwinding of the cable imparts a corresponding rotational motion on the rate governor, which, in turn, translate such motion to a braking device that imparts a braking force on the rotation of the spool to control the rate at which a person is lowered to the ground.
