Patent ID: 7637356

Claim:
An elevator system, comprising: an elevator hoistway; a plurality of hoistway doors arranged above each other each with at least one horizontally moveable hoistway door panel; an elevator car with a car door that has at least one horizontally movable car door panel; a vertically extending barrier rail fastened to the car door panel; and, two locationally fixed stopping dogs in areas lying in a vertical direction between the hoistway door panels of adjacent hoistway doors, the two locationally fixed stopping dogs being vertically spaced from each other and arranged so that in each case one of the stopping dogs limits a horizontal opening movement of the barrier rail and thereby of the car door panel when a position of the elevator car deviates in a positive or negative vertical direction by a certain minimum distance from an intended stopping position; wherein the stopping dogs are placed so that the hoistway door panel can be completely opened even though the elevator car takes up a position in which one stopping dog limits the opening movement of the barrier rail and of the car door panel as long as a coupling device that is to couple the hoistway door panel with the car door panel is no longer engaged.
