Abstract
An elevator system includes an elevator car that is movable in an elevator shaft in the vertical direction, a closed support belt guided about a lower deflection roller and an upper deflection roller and a drive machine driving the support belt. A drive connection is made between the support belt and the elevator car with a coupling device arranged on the elevator car that is coupled to a coupling element of the support belt. The coupling element is a connection element that connects two free ends of the support belt together.
Claims13
An elevator system comprising:
- a first elevator car movable in a first elevator shaft in a vertical direction;
- a closed first support means guided about a lower deflection roller and an upper deflection roller in the first elevator shaft;
- a first drive machine driving the first support means;
- a first coupling device arranged on the first elevator car;
- wherein the first support means has a first primary coupling element which, when coupled to the first coupling device, produces a drive connection between the first elevator car and the first support means whereby the first elevator car can be moved in the first elevator shaft by the first support means driven by the first drive machine;
- wherein the first primary coupling element is a connection element that connects two free ends of the first support means together;
- and
- wherein during a normal operation of the elevator system the first coupling device can be coupled to the first primary coupling element and can be decoupled from the first primary coupling element whereby the drive connection between the first elevator car and the first support means can be produced and detached respectively.
