The present disclosure relates to a car door for a lift car having a guide mechanism and a door leaf. The guide mechanism comprises in this case a sliding shoe, which is connected to the door leaf of the car door. Furthermore, the guide mechanism comprises a receiving part which surrounds the sliding shoe on at least three sides. The sliding shoe has, in a sliding direction, an extent which corresponds to at least 30% of the extension of the door leaf in this direction.

A door system for an elevator installation having an elevator car with a car door arranged to travel in an elevator shaft with shaft doors, wherein the car door is spaced from the shaft doors in a closed position of the door system. A primary pivot spindle is coupled to a pivotable door leaf of the shaft door or the car door and a secondary pivot spindle is coupled to a pivotable door leaf of the other of the car door and the shaft door. A drive unit includes a driven, pivotably mounted shaft to which a first entrainer and a second entrainer are fixed. During a pivoting movement of the shaft, the first entrainer engages a first counterpart element on the primary pivot spindle and the second entrainer engages a second counterpart element on the secondary pivot spindle to effect a pivoting movement of the door leaves.

A door system for an elevator installation having an elevator car, the door system including a pivotable first car door leaf mounted at a car door opening and a pivotable first shaft door leaf mounted at a shaft door opening of the elevator installation. At least a part of the shaft door opening is closed by the first shaft door leaf in a closed position thereof and a shaft door plane is formed along the shaft door leaf. At least a part of the car door opening is closed by the first car door leaf in a closed position thereof and a car door plane is formed along the car door leaf. The car door leaf, in an open position thereof, extends through the shaft door plane, or the shaft door leaf, in an open position thereof, extends through the car door plane.

The elevator door panel is formed of a composite material based on reinforcement fibres embedded in a polymer matrix material, the reinforcement fibres being arranged in the polymer matrix material so that the elevator door panel is stiff in a vertical plane, but can be bent to a curve around a vertical corner.
