Interface for operating an elevator car, elevator car and method of producing an elevator car

1 . An interface for operating an elevator car comprising:

an interface controller;

a foil attached to a wall surface of a wall of the elevator car;

at least one pressure-sensitive sensor adapted to receive user requests by an application of a pressure to the at least one sensor;

wherein the foil includes a protective layer arranged between the at least one sensor and an inside of the elevator car;

wherein the at least one sensor is connected to the interface controller, the interface controller being adapted for connection to a car controller of the elevator car and for transmitting the user requests received by the at least one sensor to the car controller of the elevator car; and

wherein the at least one sensor is embedded in the foil in an embedding layer of the foil, the embedding layer being arranged between the protective layer and the wall surface.

2 . The interface according to claim 1 wherein the protective layer includes at least one sign indicative of one of the user requests.

3 . The interface according to claim 1 wherein at least one of the foil, the embedding layer and the protective layer is flexible.

4 . The interface according to claim 1 wherein at least one of the foil, the embedding layer and the protective layer is transparent or at least substantially transparent.

5 . The interface according to claim 1 wherein at least one of the embedding layer and the protective layer is formed of a polymer material.

6 . The interface according to claim 1 including electric circuitry connecting the at least one sensor with the interface controller, wherein the electric circuitry is at least partially embedded in the embedding layer of the foil.

7 . The interface according to claim 1 wherein the at least one sensor includes a cavity formed therein and a membrane, and wherein the at least one sensor is adapted to sense of the pressure applied to the at least one sensor based on a bending of the membrane into the cavity.

8 . The interface according to claim 1 wherein the foil has a maximum thickness in a range of 3 mm to 5 mm.

9 . The interface according to claim 1 wherein the interface controller provides a haptic feedback upon receiving one of the user requests by injecting a charge into the at least one sensor.

10 . The interface according to claim 1 wherein the interface further comprises a projector configured for installation in a roof section of the elevator car, wherein the projector is configured to project information onto a projection surface of the elevator car.

11 . An elevator car comprising:

the interface according to claim 1 installed in the elevator car;

a wall having a wall surface facing an inside of the elevator car; and

wherein the foil of the interface is attached to the wall surface.

12 . The elevator car according to claim 11 wherein the wall has a recess formed therein, the recess including the wall surface, and wherein the foil is arranged at least partially within the recess.

13 . The elevator car according to claim 12 wherein the foil is flush or substantially flush with a further wall surface of the wall, the further wall surface being outside the recess.

14 . A method of producing an elevator car, the method comprising the steps of:

providing the interface according to claim 1 ; and

attaching the foil of the interface to an interior wall surface of a wall of the elevator car wherein the at least one sensor is available for receiving user requests by an application of pressure to the at least one sensor from a user inside the elevator car;

wherein the foil of the interface is attached within a recess of the interior wall surface of the wall of the elevator car such that the foil is substantially flush with a further wall surface.
