Problems solved by technology

If the landing doors are jammed in the open position and the car leaves, there is a risk of people falling into the elevator shaft through the open door
As long as the car doors are jammed in the open position and the car is moving there is a risk of injury to passengers if they swing outward through the open door

Embodiment Construction

[0015] figure 1 A simplified and schematic front view showing a type of elevator arrangement according to the invention in which two elevator cars 10 and 20 run in the same elevator shaft 1 . The first or uppermost elevator car 10 is driven by a first hoisting machine 14 equipped with a traction sheave 15 and a diverting pulley 16 . In this example the hoisting machine 14 is placed in a separate machine room 2 above the elevator shaft 1 but it could also be placed at the upper part of the elevator shaft 1, either on the wall of the elevator shaft 1 or in the elevator car 10, 20 guide rails at 3 places.

[0016] The hoisting ropes 11 are installed between the first elevator car 10 and its counterweight 13, which may also be a compensating weight. The hoisting rope 11 in all embodiments of the invention may be a single rope or a bundle of similar parallel ropes. The first end of the hoisting rope 11 is fixed at the upper part of the uppermost elevator car 10 and the hoisting ...

Abstract

The invention relates to a method and an arrangement for closing the doors of an elevator comprising at least one elevator shaft (1, 1a, 1b) in which along guide rails (3 , 3a, 3b) running cars (10, 20) equipped with car doors (9a), landing doors (17a) at each landing floor (4, 4a, 4b), hoisting machinery (14, 24), the necessary roping system and shaft equipment, and the control system (10a) for controlling the movement of the elevator. According to the traffic situation controlled by the control system (10a) of the elevator, the door opening time of the car door (9a) and the landing floor door (17a) is shortened by accelerating the closing of the doors (9a, 17a), and passengers are informed about the accelerate.

Description

technical field [0001] The invention relates to a method for closing elevator doors as defined in the preamble of claim 1 and an arrangement for closing elevator doors as defined in the preamble of claim 7 . Background technique [0002] The solution according to the invention is suitable for all kinds of elevator systems in which automatic doors are used, and in particular the solution according to the invention is suitable for use in multi-car elevator shaft systems. The term "multi-car hoistway system" in this connection means an elevator system in which two or more elevator cars run independently of each other in one elevator shaft. The system may include only one elevator shaft or two elevator shafts. In the case of an elevator shaft, each elevator car can move independently, so they can stop on a floor, move down or move up. The elevator's control system tracks the position and movement of the cars so that collisions do not occur. In the case of two elevator shafts,...
