US 11,807,497 B2 · Elevator system

Abstract

An elevator system includes an elevator car movable in an elevator shaft, a suspension means extending in the elevator shaft, a drive machine associated with the suspension means and a controllable coupling device arranged on the elevator car. The suspension means has a coupling element that the coupling device can be coupled to and uncoupled from, as a result of which a drive connection between the elevator car and the suspension means can be established and released. The elevator system has a guide system guiding the coupling element during a movement in the elevator shaft. The guide system has a guide that is stationary relative to the elevator shaft and a runner that is connected to the coupling element via a connection and is guided along the guide. The connection between the coupling element and the runner enables a relative movement between the runner and coupling element.

An elevator system comprising:

an elevator car movable in an elevator shaft;
a suspension means extending in the elevator shaft;
a drive machine associated with the suspension means;
a controllable coupling device arranged on the elevator car;
wherein the suspension means is attached to a coupling element adapted to couple to and uncouple from the controllable coupling device to respectively establish and release a drive connection between the elevator car and the suspension means, and when the drive connection is established the coupled elevator car is movable in the elevator shaft by the suspension means driven by the drive machine;
and
a guide system guiding the coupling element during movement of the elevator car, the guide system having a guide that is stationary relative to the elevator shaft and a runner connected to the coupling element via a connection, the runner being guided along the guide by the guide, and wherein the connection between the coupling element and the runner enables relative movement between the runner and the coupling element.
