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 apparatus arranged on the elevator car. The suspension means has a coupling element that the coupling apparatus can be coupled to by assuming a coupled position and from which the coupling apparatus can be uncoupled by assuming an uncoupled position, 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 securing device that can assume a securing position and a release position and that, in the securing position, secures the coupling apparatus in the coupled position against leaving the coupled position.
Claims10
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 apparatus arranged on the elevator car and being operable between a coupled position and an uncoupled position;
- a securing device;
- wherein the suspension means has a coupling element to which the coupling apparatus is coupled in the coupled position and from which the coupling apparatus is uncoupled in the uncoupled position to respectively establish and release a drive connection between the elevator car and the suspension means, and when drive connection is established the elevator car is movable in the elevator shaft by the suspension means driven by the drive machine;
- wherein the securing device is operable between a securing position and a release position and, when in the securing position, the securing device secures the coupling apparatus in the coupled position against leaving the coupled position;
- and
- wherein the securing device has a sensor assembly that detects whether the securing device is located in the securing position, and wherein the elevator system has a control apparatus in communication with the sensor assembly, the control apparatus allowing the elevator car to be moved in the elevator shaft only when the sensor assembly detects that the securing device is located in the securing position.
