ABSTRACT:
This invention relates to 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 device wherein a person secured to one member of the closed loop of cord depending from the frictionally controlled cord release device by means of a harness is able to controll one's descending speed by exerting a small amount of tension on the other member of the closed loop of cord in the descending process. In the ascending process, a person secured to one member of the closed loop of cord by a harness is able to elevate oneself by using a stirrup slidably secured to the other member of the closed loop of cord 1 which stirrup includes a locking means that grabs the other member of the closed loop of cord when one stands on the stirrup applying a weight thereon, while the stirrup slides substantially freely on the other member of the closed loop of cord when no weight is applied thereon. The person secured to one member of the closed loop of cord propels oneself upwards by repeating the combination of movements of pulling up the stirrup by bending the knees and standing up straight while shifting the body weight from the harness to the stirrup.
