摘要： This invention relates to an emergency escape system for escape from elevated structures such as sky-scrapers, high-rise apartment or office buildings, etc., which system enables one to lower oneself from any level of a high-rise building to ground level all by oneself without requiring any help from rescue crews wherein, with the minimum amount of physical effort, the descending motion and speed is completely controlled by the descending person. The sky-ride emergency system comprises a closed loop of rope or cable wound on a friction drum over a number of complete laps in a substantially tight relationship. The cylindrical surface of the friction drum nonrotatably secured to an elevated level has a high friction coefficient. The closed loop of rope depending from the friction drum includes at least one securing means such as a hook or ring affixed to the rope. The lower extremity of the closed loop of rope depending from the friction drum reaches down to a lower level such as ground level. A rope guide means slidably guides and confines the portion of rope wound on the friction drum. The frictional grip of the rope on the friction drum resulting from a pull on one rope member depending from the friction drum by the weight of an evacuee secured to said one rope member can be altered to a great extent by exerting a weak pull of varying magnitude on the other rope member depending from the friction drum. As a consequence, an evacuee wearing a harness secured to one of two rope members depending from the friction drum is able to suspended oneself in midair or lower oneself by controlling the small amount of pull exerted on the other of two rope members depending from the friction drum by the evacuee.

摘要： This invention relates to a self-contained and self-sufficient device for lowering and raising oneself vertically without relying on any mechanical power, or any man power external to the system wherein the direction and speed in the vertical movement of a person is fully controlled with ease by that person himself or herself. The sky-ride vertical mobiity system of the present invention comprises a frictionally controlled rope release device secured to an upper level and a closed loop of rope depending from the frictionally controlled rope release device that is wrapped around a friction drum included in the frictionally controlled rope release device. Exertion of a pull of very small magnitude on one member of the closed loop of rope depending from the frictionally controlled rope release device creates a frictional braking of very large magnitude that is capable of suspending a heavy object secured to the other member of the closed loop of rope motionlessly in midair or lower it at a safe speed. A person secured to one member of the closed loop of rope by means of a harness worn by that person and secured to one member of the closed loop of rope can control his or her own descending motion by exerting small amount of pull on the other member of the closed loop of rope and varying thereof. The sky-ride vertical mobility system including a one-way frictionally controlled rope release device with a friction drum equipped with a ratchet mechanism enables one to raise himself or herself by using a harness secured to one member of the closed loop of rope depending from the one-way frictionally controlled rope release device and a stirrup equipped with a one-way grip slidably engaged by the other member of the closed loop of rope depending from the one-way frictionally controlled rope release device.
