ABSTRACT:
An apparatus for selecting an elevator cabin at a transportation installation, especially an elevator system, for direct travel of an elevator group, controlled by means of a group control, possesses additional storey call transmitters and storey call storages. The storey call storages are connected with a call blocking device having infed thereto a first signal train or sequence produced during scanning of the storey call storages. The call blocking device possesses further inputs, to which there is infed information blocking already allocated calls, so that at its output there appears a second signal train or sequence no longer containing the allocated calls. This output is connected with a respective input of call allocation devices operatively associated with the elevators. The call allocation devices are operatively interconnected with one another by means of a switching circuit. Upon the occurrence of a coincidence signal of an elevator which is ready to service a storey call, the related call allocation device is prepared for the call allocation. Upon subsequent occurrence of a storey call there appears at the output of the call allocation device a control signal which triggers the direct travel.
