  • US Pat. No. 5,921,351 an elevator system is known in which a car is moved along a predetermined path by a drive mechanism.
  • This drive mechanism has a plurality of driven belts arranged one behind the other. The drive force is transmitted from the belt to the car via a frictional connection between a friction surface of a belt and an associated surface of the car.
  • the object of the invention is to specify an elevator system and a method which enable an improved mode of operation.
  • the elevator system can in particular serve to transport people in one or more cabins.
  • the task here may be to enable people to be transported in at least one cabin in an improved manner.

  • the friction drive units are arranged on at least one shaft wall of the shaft, the friction drive units each having at least two friction wheels, the car being movable during operation in each shaft section by at least one of the friction drive units and the at least one friction drive unit being adjustable in at least one shaft section is drivable, so that during operation the car can be moved at least in this shaft section at a substantially continuously adjustable speed.
  • this is achieved in that the speed of each friction drive unit can be set independently of the other friction drive units.
  • a method for driving cars of a proposed elevator system can be specified, the speed of at least one car being continuously adjusted by means of friction drive units as a function of at least one operating state of at least one other car.
  • a method for transporting people with a proposed elevator system can be specified, wherein at least two cars are moved in at least two shafts by means of friction drive units arranged on shaft walls and wherein the cars move through the shafts at at least substantially continuously adjustable speeds during operation become.
  • At least one of the friction drive units has an endless belt, that the friction wheels of this friction drive unit are enclosed by the endless belt and that at least one of the friction wheels can be driven by a drive unit.
  • friction wheels are to be understood as wheels for transmitting a traction force to the elevator car or to a belt.
  • the traction force can be transmitted directly from the friction wheel to a part of the cabin, that is to say the cabin itself, or to an additional part specially designed for power transmission, which is attached to the cabin.
  • a friction wheel is also to be understood as meaning wheels which do not transmit the tractive force directly to the cabin but, for example, to an endless belt, the belt transfers the traction force through friction to the cabin or a part attached to the cabin for this purpose.
  • the car has at least one traction plate to which, during operation, a drive force for moving the car in the shaft is temporarily transmitted by at least one of the friction drive units.
  • This enables an advantageous power transmission to the cabin.

  • the friction drive unit or the friction drive units of each shaft section is or are controllably drivable, so that during operation the car at least substantially entire shaft can be moved at essentially infinitely variable speed. In this way, in particular, a significant improvement in driving comfort for people can be achieved. It is advantageous that a plurality of friction drive units are used in each shaft section to drive the car, the friction drive units being arranged in pairs on a shaft wall of the shaft or on one side of the car.
  • friction drive units are used to drive the car in each shaft section, with at least two friction drive units, in particular two pairs of friction drive units, being arranged on two opposite sides of the shaft or on two opposite sides of the car.

  • driving comfort is improved in particular in an improved manner.
  • the drive device reduces the speed of a car, the speed of which is reduced in relation to at least one operating state of at least one of the other cars, to such an extent that the car is prevented from stopping before its next scheduled stop at a stop. Avoiding an additional stop for a car is a preferred specification for improving driving comfort.
  • the cars are moved with at least one standard speed and at least one reduced speed by the friction drive units.

In such an embodiment, a partial shaft is provided on both sides of the main shaft. One of the car units is always in the shaft, while the other car unit is parked in one of the two sub-shafts. If a car has to be removed from the shaft, for example due to a defect, the car unit which is located in the shaft can be moved into the free partial shaft after the car has entered and braked, and there be parked.
