Elevator system with multiple cars

PURPOSE: To save a required floor space by arranging the plurality of independently operated elevator cars to be moved individually in a vertical elevator shaft extended to multiple stories of a building, and by controlling them by a signal processing means such as a computor. CONSTITUTION: Elevator cars C 1 -CN (N is an integer) are arranged in a vertical elevator shaft 12 of a multi-storied building 10, for example, to serve with all the elevator cars for F 1 -F 16 -story floors, and car storing spaces 12L, 12U are provided below the lowermost story and over the uppermost story. Counterweights are attached to the respective elevator cars to be connected to the respective cars C 1 -C 3 via cables 24, 28, 34. The elevator cars are controlled to be moved from one end terminal to the other end terminal in order under operation by control signals from a digital computor, so as to serve concurrently for plural service stories by the plurality of the elevator cars. A floor space required for this elevator system is remarkably saved thereby. COPYRIGHT: (C)1995,JPO
