ABSTRACT:
An elevator evacuation apparatus is described, which enables a person(s) trapped in a stopped elevator car to pull a emergency cable outside a car window to activate a cam based pulley and gear mechanism which in turn intermittently releases and actuates a brake, thereby slowly lowering the stopped car until arriving at a correct floor. A number of embodiments are possible.
