ABSTRACT:
A descent vehicle for persons to lower themselves in a controlled manner by gravity from a high place or building on the outside. The unit rides on a rope secured to the building or high place and allows riders of different weights sitting on the seat of the vehicle holding on to handles to ride one at a time safely down from any height at about walking speed. Two main parts inside housing, pre-adjusted by the rider, bend and squeeze the rope to produce the desired safe descent speed. A hand brake on the unit is an additional safety feature.
