More Information
Summary:One of a plurality of cars ( 17, 18 ) traveling in a hoistway ( 10 ) of an elevator system ( 9 ) may be diverted to the hoistway overhead ( 31 ) or pit ( 36 ) to enable another of the cars to gain access to a floor near or at a terminal floor ( 11, 14 ). When such car is at its last stop with doors open, visual ( 40 ) and audible ( 41 ) indicators present ( 57, 58 ) messages to the effect that this is the last stop and passengers should exit. After car doors are closed ( 66 ), visual and audible messages ( 68, 69 ) relate to the car going to the pit or overhead and that passengers may push any button (to reopen doors). Thereafter, the car moves ( 75, 76 ) to the overhead ( 31 ) or the pit ( 36 ) and presents ( 82, 83 ) visual and audible messages to the effect that passengers did not exit at the correct floor and must wait while the other car makes a stop. Once the terminal floor is clear, the diverted car will run ( 87 - 89 ) to that floor, presenting ( 92, 93 ) visual and audible messages to the effect that passengers should exit once the doors are open and reenter their service requests.
