Abstract

An elevator installation has elevator operating devices arranged on floors of a building and communicatively connected to an elevator controller. The elevator operating devices include main operating devices configured for inputting a destination floor desired by a passenger and for outputting travel information, and at least one secondary operating device arranged on one of the floors. The secondary operating device is next to the main operating device on the one floor and is communicatively connected to the elevator controller. The secondary operating device has a touch-sensitive screen system that confirms a destination floor, input by touch, by a tactilely perceptible feedback in order to support a passenger with a physical limitation when inputting a call. The elevator controller determines travel information for the destination floor input on the secondary operating device and communicates this information to the passenger by the main operating device arranged next to the secondary operating device.

First claim

The invention claimed is:

1. An elevator installation having at least one elevator car controlled by an elevator controller for movement between floors of a building, the elevator installation comprising:
a plurality of main operating devices communicatively connected to the elevator controller and arranged on the floors, wherein each of the main operating devices is configured for inputting destination floors desired by passengers and for outputting travel information related to the destination floors;
a secondary operating device arranged on one of the floors next to the main operating device arranged on the one floor and communicatively connected to the elevator controller;
wherein the secondary operating device has a touch-sensitive screen system configured to confirm a destination floor input by touch by generating tactilely perceptible feedback to support a passenger having a physical limitation inputting the destination floor; and
wherein the elevator controller is configured to determine travel information for the destination floor input on the secondary operating device and to communicate the determined travel information to the passenger by the main operating device arranged next to the secondary operating device.

2. The elevator installation according to claim 1 wherein each of the main operating devices and the secondary operating device has a housing, wherein the housing of the secondary operating device is arranged adjacent to the housing of the main operating device next to the secondary operating device.

3. The elevator installation according to claim 1 wherein the main operating device next to the secondary operating device includes: a touch-sensitive screen configured to display input fields assigned to the destination floors, to detect a touch of one of the input fields, and to display travel information determined for the destination floor to which the touched input field is assigned; and an audio device configured to announce the determined travel information.

4. The elevator installation according to claim 1 wherein each of the main operating devices includes: a touch-sensitive screen configured to display input fields assigned to the destination floors, to detect a touch of one of the input fields, and to display travel information determined for the destination floor to which the touched iput field is assigned; and an audio device configured to announce the determined travel information.

5. The elevator installation according to claim 1 wherein the main operating devices and the secondary operating device are communicatively connected to the elevator controller by a communication network.

6. The elevator installation according to claim 5 wherein the communication network transmits electrical energy and the main operating devices and the secondary operating device are supplied with the electrical energy from the communication network.

7. The elevator installation according to claim 1 wherein the touch-sensitive screen system includes an actuator that, when actuated by a control voltage, causes a surface of the screen system to vibrate thereby generating the tactilely perceptible feedback.

8. The elevator installation according to claim 1 wherein the touch-sensitive screen system includes a force measuring device and a control device, wherein the force measuring device measures a force with which a passenger presses on a user interface of the touch-sensitive screen system, and wherein the control device only registers the measured force as a triggering force if the measured force reaches a specified threshold value.

9. The elevator installation according to claim 1 wherein each of the main operating devices participates in the determination of the travel information for the input destination floor.

10. A method for operating an elevator installation having a plurality of main operating devices communicatively connected to an elevator controller and arranged on floors of a building, a secondary operating device arranged on one of the floors separately from the main operating device arranged on the one floor, the secondary operating device being communicatively connected to the elevator controller, wherein the secondary operating device has a touch-sensitive screen system configured to confirm a destination floor input by touch by generating tactilely perceptible feedback to support a passenger with a physical limitation inputting the destination floor, the method comprising the steps of:
the elevator controller receiving a destination call input by a passenger;
the elevator controller determining a first identifier using the destination call, wherein the first identifier identifies the main operating device or the secondary operating device from which the received destination call originated;
the elevator controller determining travel information for the received destination call;
when the destination call originated from the secondary operating device, the elevator controller determines a second identifier that identifies the main operating device that is arranged next to the secondary operating device; and
communicating from the elevator controller the travel information determined for the destination call input on the secondary operating device to the passenger by the main operating device identified by the second identifier.

11. The method according to claim 10 including displaying input fields assigned to the destination floors on a touch-sensitive screen of each of the main operating devices, detecting a touch of one of the input fields and displaying the determined travel information for the destination floor call to which the touched input field is assigned, and announcing the determined travel information by an audio device.

12. The method according to claim 10 wherein the touch-sensitive screen system of the secondary operating device includes an actuator, operating the actuator with a control voltage to generate a vibration of a surface of the touch-sensitive screen system, and wherein the vibration is the tactilely perceptible feedback.

13. The method according to claim 10 wherein the touch-sensitive screen system includes a force measuring device and a control device, measuring a force with which a passenger presses on a user interface of the touch-sensitive screen system with the force measuring device, and wherein the measured force is only registered as a triggering force by the control device if the measured force reaches a specified threshold value.
