Abstract
A fire escape device enabling a person to escape from a multi-story building. The fire escape device of the invention comprises two sets of planetary gears which operatively interconnect a winding drum to the main shaft of a fan assembly. During operation, as the cable is unwound from the drum, the sets of planetary gears cause the shaft of the fan and correspondingly, the fan blades themselves to rotate at great speed thereby braking and hence controlling the rate at which the cable is released from the winding drum.
