ABSTRACT:
This invention relates to a device for transporting a person or persons vertically that comprises a closed loop of cord depending from a cylindrical roller with frictional braking means on which roller the cord is wound over a plurality of laps wherein the speed of the lowering motion of one member of the closed loop of cord depending from the cylindrical roller is effortlessly controlled by a small amount of tension exerted on the other member of the closed loop of cord depending from the cylindrical roller as the small amount of tension exerted on the other member of the closed loop of cord controls the magnitude of the frictional braking on the cylindrical roller. Consequently, a person secured to the one member of the closed loop of cord is able to lower oneself at a safe speed with ease by exerting a small amount of pull on the other member of the closed loop of cord. The cylindrical roller with frictional braking means equipped with a rachet means enables a person to raise as well as lower oneself with ease when secured to one member of the closed loop of cord and using a stirup means slidably secured to the other member of the closed loop of cord wherein the stirup locks onto the other member of the closed loop of cord when the weight of the person is exerted thereon.
