Abstract
A floor call registering circuit for an elevator system includes a keyboard at each floor for inputting the destination floors. The call registering circuit at the main stopping location permits only travels to destination floors which are allocated to a certain group of destination floors. According to an alternate embodiment, the call registering circuit is provided either with a pulse generator or with a decade keyboard. If the keyboard at the main stopping location has keys for all the destination floors, a circuit is provided which frees the destination floor calls allocated to the certain group of destination floors and blocks the destination floor calls lying outside the certain group of destination floors.
Claims16
In an elevator installation which includes at least one elevator having a car provided with at least one compartment, wherein at least one main stopping location and a number of adjacent floors are provided, and command input devices are present for the calling of cars to the floors and for the input of travel destination wishes and the elevator carries out only travel wishes to one certain group of destination floors, the improvement comprising:
- the command input devices are call registering circuits arranged externally of the car on the floors and including circuit means for the prevention of the execution of travel wishes at least in the direction of travel away from the main stopping location to destination floors lying outside the certain group of destination floors.
A floor call registering circuit for an elevator system comprising:
- a keyboard having keys for inputting desired destination floors, a plurality of flip-flops, each having an input connected to an associated one of said keys, an OR-element having a plurality of inputs each connected to an associated output of one of said flip-flips, and a multiplexer having a plurality of inputs each connected to an associated output of one of said flip-flops and a first input connected to an output of said OR-element for generating a floor call signal to a control circuit for an elevator.
