Embodiment Construction

[0063] The present invention provides a portable apparatus for controlled descent of a person (or other body of mass) from a height by means of a cable wound onto a reel of the apparatus. According to a preferred embodiment of the present invention, the user straps on the apparatus, attaches the free end of the cable to a solid fixed point, and lowers himself out of a window or other egress point from which he or she can descend to a lower point. The most common anticipated use for the apparatus is for escaping from high building floors down the outside of the building.

[0064] The controlled descent is effected automatically by two energy transfer mechanisms that convert the energy of the falling person into heat and dissipate that heat: a static mechanism based on friction of the cable on a drum takes up most of the descent energy and a dynamic mechanism based on friction exerting arms, that are coupled to the reel on which the cable is wound, and interact with the drum, affected b...

Abstract

A device for facilitating a controlled descent of a body, the device comprising a rotatable reel around which at least a portion of a cable is wound, a first end of the cable secured to the reel and a second end or the cable free; a friction drum mounted coaxially around the reel, the cable, upon leaving the reel wound at least partially around the drum; a carrier on which the reel and the drum are mounted; wherein the reel is provided with braking means for braking rotational motion of the reel and for balancing descending speed or the body.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a self-braking safety apparatus adapted to permit the rapid descent of persons on the outside of buildings or the like in cases of emergency. More particularly it relates to a device and method for. BACKGROUND OF THE INVENTION [0002] It is at times necessary to evacuate upper floors in buildings or other high-elevations without having access to normal routes of egress. The cause is usually a fire on a lower floor that prevents persons on upper floors from passing through the lower floor and get down to safety. [0003] While fire is the most common case there are many others such as events that render the building structure in danger of imminent collapse, such as earthquakes or other events that result in an extensive damage. [0004] A related result of terrorism and of skyscraper fire tragedies is a change in the public's perception of high building safety. A dependable, portable safe device for rapid escape in the event o...
