Abstract:
1. A method of monitoring a door gap to determine whether a proper final closed position of doors exists after a closing of doors of rail vehicles, or other vehicles or elevators, the vehicles or elevators having at least one door leaf, which at least one door leaf is equipped on its main closing edge with an elastically deformable or elastically mounted profile, whose position and/or shape is detected by electric, pneumatic, optical, inductive, capacitive or magnetic sensors or a combination of such sensors in connection with an electronic monitoring system which analyzes the signals of the sensors and, if applicable, determines the existence of the door gap due to problems which could include a jamming-in of an object or a person in the door gap, the method steps comprising: moving the doors to the closed position; activating the electronic monitoring system after a predetermined time delay after the doors are closed; monitoring the profiles and determining a final closed position of the profiles by the electronic monitoring system; and deactivating the electronic monitoring system after a predetermined time interval or when a predetermined event occurs.
