ABSTRACT:
An elevator car suitable for use by physically handicapped passengers can be selected from a group of elevator cars under the control of a group control wherein call registering and indicating devices positioned at the floors served by the cars include an additional key for activating a switching circuit. The switching circuit is connected to a car load memory and a memory for storing the alighting calls for target floors where passengers are to leave the cars. A first condition is satisfied when there is no alighting call for a car, no exiting passenger to interfere with an entering wheelchair, and a second condition is satisfied when the load, number of passengers, in a car is smaller than a certain load limit value indicating sufficient space for the wheelchair. The switching circuit is also connected to a comparator which compares the travelling time required for a car to travel from its current position to the call entry floor with the traverse time needed by a physically handicapped person to traverse the path between the actuated call registering and indicating device and the shaft door of the elevator concerned. A third condition for the selection of a car is fulfilled when the travelling time is greater than the traverse time. When all three conditions are fulfilled for a car, that car is enabled to participate in the call allocation procedure to determine which car in the group will serve the call.
