Abstract
An elevator car operating panel includes a plurality of push buttons corresponding to floors of a building, wherein the push buttons act on a touch screen to register elevator calls. The push buttons are mounted on an outer surface of the touch screen at locations corresponding to sensors behind the touch screen. A method to modernize and/or update a touch screen elevator car operating panel includes mounting at least one push button on a touch screen to act on the touch screen to register elevator calls.
Claims11
A push button for use with an elevator car operating panel having a touch screen and at least one sensor mounted behind the touch screen and corresponding to a floor of a building, the at least one sensor being responsive to the touch of a human at a front surface of the touch screen adjacent the at least one sensor for registering an elevator call for the floor, the push button comprising:
- the push button having a central part responsive to application of a predetermined applied pressure;
- and
- means mounting the push button on the front surface of the touch screen adjacent the at the at least one sensor whereby when said push button central part is actuated by application of the predetermined applied pressure, an electromagnetic field generated by the at least one sensor is disturbed without said push button central part contacting the touch screen, and the at least one sensor responds by registering the elevator call for the floor.
A car operating panel of an elevator comprising:
- a touch screen having a front surface;
- a plurality of sensors mounted behind said touch screen each corresponding to an elevator call to be registered for an associated floor;
- a plurality of push buttons each adapted to be actuated by a human finger and each corresponding to one of said sensors;
- and
- means for mounting said push buttons on said front surface of said touch screen, each said push button being mounted adjacent the corresponding one of said sensors whereby actuation of said push buttons disturbs an electromagnetic field generated by said corresponding sensor without contacting said touch screen and causes said corresponding sensor to register the elevator call for the associated floor.
