Abstract
Abstract A portable, self-contained emergency fire-escape mechanism is provided for use in escaping from fires or other emergencies occuring in hotels, apartments, or office buildings and the like. The mechanism includes an anchoring means which may be mounted by the user on a window sill or the like and which is constructed so that it may be readily positioned by the user on the exterior of the structure. The anchoring means is connected with a lowering assembly having one end of a flexible cable connected thereto. The cable is contained in a canister and is disposed therein in a manner to be readily payable out therefrom. The canister is provided with harness which is arranged so as to engage and hold the body of a person escaping from the building. The lowering assembly is constructed to controllably pay out the cable from the canister.
