ABSTRACT:
This invention discloses a self-sufficient device enabling a person to descend and ascend with ease, which device includes a closed loop of cord depending from a frictionally controlled cord release apparatus that exerts braking on the looping movement of the closed loop of cord in one direction releasing the first member and taking up the second member thereof, while it allows substantially free looping movements in the other direction releasing the second member and taking up the first member of the closed loop of the cord, wherein the first member of the closed loop of cord includes a harness securely affixed thereto and the second member includes a handle and a stirrup slidably secured thereto, which handle and stirrup freely slide on the second member of the closed loop of cord when no load is exerted thereon, while the handle and stirrup grabs the second member of the closed loop of cord when a load is exerted thereon.
