An elevator capable of transporting persons or goods in any desired direction along a straight or curving path utilizes an endless guide tube comprising tracks and connecting sections and containing discrete transmission members driven along the tube by engagement with the teeth of a rotor. One of the transmission members projects through a slot running the length of the tube and is coupled to the elevator car, while the teeth of the rotor engage with the remaining transmission members through the same slot. |
