Situation-dependent reaction in the case of a fault in the region of a door of an elevator system

An elevator system comprising:

• an elevator car having a car door;
• a drive unit connected to said elevator car for moving the elevator car (2;
• 12;
• 28) along an elevator shaft wall provided with shaft doors;
• a controller connected to said drive unit for controlling movement of said elevator car along the elevator shaft wall;
• a detecting means mounted in at least one of a region of each of the shaft doors and a region of said car door and being connected to said controller for generating fault information to said controller;
• and
• a status detecting unit connected to said controller for generating to said controller status information about a position and a speed of said elevator car whereby, in case of a fault in the region of one of the shaft doors, said controller moves said elevator car, after any passengers have disembarked, into a position directly behind the one shaft door in order to prevent a person from being able to fall through an open shaft door into said elevator shaft.

• a controller connected to said drive unit for controlling movement of said elevator car along the elevator shaft wall;
• a detecting means mounted in at least one of a region of each of the shaft doors and in a region of said car door for generating fault information, said detecting means being connected to said controller for generating to said controller said fault information;
• and
• a status detecting unit connected to said controller for generating to said controller status information about a position and a speed of said elevator car whereby said detecting means ascertains whether a gap formed by an incorrectly closed one of the shaft doors or said car door is substantial or insubstantial, said controller responding to said fault information representing a presence of an insubstantial gap by moving said elevator car without restriction and placing a service call and said controller responding to said fault information representing a presence of a substantial gap at one of said shaft doors by moving said elevator car to a floor that can be reached without passing the one shaft door having the substantial gap in order to let passengers disembark.
