ELEVATOR SYSTEM AND METHOD FOR INSTALLING AN ELEVATOR

摘要

The invention relates to an elevator system and also to a method for installing an elevator. The elevator system comprises an elevator hoistway bounded by a surrounding structure, two or more entrances to the elevator hoistway, guide rails, which are fitted into the elevator hoistway and also an elevator car with door(s), which elevator car is configured to be movable in the elevator hoistway between the aforementioned entrances to the elevator hoistway along a vertical trajectory determined by the guide rails. Each aforementioned entrance to the elevator hoistway is bounded by a door frame, onto which a hoistway door is fitted. The door opening of the elevator car is bounded by a door frame, onto which the car door is fitted. The elevator system comprises for each aforementioned entrance to the elevator hoistway a marking piece fixed immovably to the frame of the hoistway door, said marking piece indicating the location in the elevator hoistway of the entrance to the elevator hoistway. The elevator system also comprises a reader moving along with the elevator car, said reader being fixed immovably to a fixing point on the frame of the car door and being configured to read the aforementioned marking piece.

1. Elevator system, comprising:
an elevator hoistway bounded by a surrounding structure; two or more entrances to the elevator hoistway; guide rails, which are fitted into the elevator hoistway; an elevator car with door(s), which elevator car is configured to be movable in the elevator hoistway between the aforementioned entrances to the elevator hoistway along a vertical trajectory determined by the guide rails; and in which elevator system each aforementioned entrance to the elevator hoistway is bounded by a door frame, onto which a hoistway door is fitted; which door frame of the hoistway door is formed from a horizontal door header and a horizontal lower frame member as well as side frame members connecting them; and in which elevator system the door opening of the elevator car is bounded by a door frame, onto which the car door is fitted; which door frame of the car door is formed from a horizontal door headerand a horizontal lower frame member as well as side frame members connecting them; wherein the elevator system comprises for each aforementioned entrance to the elevator hoistway a marking piece indicating the location in the elevator hoistway of the entrance to the elevator hoistway, which marking piece is fixed immovably to a fixing point on the door header of the hoistway door; and in that the elevator system comprises a reader moving along with the elevator car, said reader being fixed immovably to a fixing point on the door header of the car door and being configured to read the aforementioned marking piece when the reader has reached the individual reading point for the marking piece in the elevator hoistway; and in that each aforementioned frame of a hoistway door is matched to the frame of the car door in such a way that the interpositioning of the fixing point of a marking piece on the door header of a hoistway door and the fixing point of the reader on the door header of the car door is constant when the top surface of the bottom frame member of the car door is situated at the same height as the top surface of the bottom frame member of the hoistway door.
