摘要

An elevator apparatus including a position determination apparatus for determining the position of an elevator car inside an elevator shaft, the position determining apparatus including a marking unit for marking a position of the elevator car, and a detection unit for detecting the marking unit, the marking unit being arranged on one of the shaft doors and the detection unit being arranged on the associated car door or vice versa for the purpose of improved installation.

主权项

1. An elevator apparatus for conveying at least one of people and items inside an elevator shaft of a three-dimensional structure having at least two floors, said elevator apparatus comprising:
an elevator car for accommodating the at least one of people and items to be conveyed, having at least one car door for at least one of opening and closing the elevator car; an elevator shaft having at least one shaft opening for accessing at least one of the elevator shaft and the elevator car; at least one shaft door to at least one of open and close access to the at least one of the elevator shaft and the elevator car; a position determination apparatus for determining a position of the elevator car inside the elevator shaft comprising a marking unit for marking the position of the elevator car, and a detection unit for at least one of detecting and reading the marking unit, wherein the position determination apparatus is arranged with one of the marking unit arranged on one of the shaft doors and the detection unit arranged on the associated car door, and the marking unit arranged on one of the car doors and the detection unit is arranged on the associated shaft door; and a control unit for controlling at least movement of the elevator car in the elevator shaft, wherein when the elevator car is moving in the elevator shaft the position determination apparatus sends the determined position of the elevator car in the elevator shaft to the control unit, and the control unit stops the elevator car at a predetermined position corresponding to a region of the at least one shaft opening based on the determined position from the position determination apparatus such that the at least one car door and the at least one shaft door associated with the at least one car door overlap each other when the elevator car is stopped at the predetermined position to provide access to the elevator car, wherein at least one of the associated shaft door and the car door has at least one of a recess and an indentation on their mutually facing sides, which uncovers an intermediate space between the shaft door and the associated car door, and wherein at least one of the marking unit and the detection unit is arranged in the intermediate space formed by at least one of the recess and the indentation.
