Elevator system

An elevator system, comprising:

• a first elevator car and a second elevator car each movable in a first elevator shaft in the vertical direction;
• a closed support means guided about a lower deflection roller and an upper deflection roller in the first elevator shaft;
• a drive machine driving the support means;
• an actuatable coupling device arranged on the first elevator car and another actuatable coupling device arranged on the second elevator car;
• the support means having a first coupling element and a second coupling element to and from which the coupling devices can be coupled and decoupled, whereby a drive connection can be established and detached between the elevator cars and the support means and the elevator cars can be moved in the first elevator shaft by the support means driven by the drive machine;
• wherein the first and second coupling elements of the support means are arranged such that in a movement of the first elevator car coupled to the support means via the associated coupling element, from a lower end position to an upper end position in the elevator shaft, or vice versa, neither of the coupling elements is guided about one of the deflection rollers;
• wherein the first elevator car and the second elevator car are movable in the vertical direction in a second elevator shaft arranged in parallel with the first elevator shaft;
• a first transfer device for displacing the elevator cars from the first elevator shaft to the second elevator shaft;
• a second transfer device for displacing the elevator cars from the second elevator shaft to the first elevator shaft;
• and
• wherein a movement of the elevator cars in the second elevator shaft is realized analogously to the movement in the first elevator shaft.

An elevator system, comprising:

• a first elevator car and a second elevator car each movable in a first elevator shaft in the vertical direction;
• a closed support means guided about a lower deflection roller and an upper deflection roller in the first elevator shaft, the support means extending along and spaced from a side of each of the first and second elevator cars;
• a drive machine driving the support means;
• an actuatable coupling device arranged on the first elevator car and another actuatable coupling device arranged on the second elevator car;
• the support means having a first coupling element and a second coupling element to and from which the coupling devices can be coupled and decoupled, whereby a drive connection can be established and detached between the elevator cars and the support means and the elevator cars can be moved in the first elevator shaft by the support means driven by the drive machine;
• wherein the first and second coupling elements of the support means are arranged such that in a movement of the first elevator car coupled to the support means via the associated coupling element, from a lower end position to an upper end position in the elevator shaft, or vice versa, neither of the coupling elements is guided about one of the deflection rollers;
• and
• wherein the first and second coupling elements of the support means are arranged such that in a movement of the first elevator car coupled to the support means via the one of the coupling elements, from the lower end position to the upper end position, or vice versa, neither of the coupling elements contacts with either of the deflection rollers.
