Definitions
- the invention relates to an elevator system according to the preamble of claim 1.
- Elevator systems are used to transport people and/or goods between floors of buildings.
- at least one elevator car that can accommodate people and/or goods is moved in an elevator shaft, in particular vertically between floors.
- an elevator system can have just one elevator car or several elevator cars that can be moved independently of one another in travel paths of the elevator shaft that are arranged next to one another.
- An elevator system with several travel paths for elevator cars can be referred to as a group elevator.
- the travel paths for the elevator cars of a group elevator are usually not separated from one another by walls, but by intermediate supports to which components of the elevator system, in particular guide rails for guiding the elevator cars, are attached.
- Guide rails are usually made up of individual guide rail pieces that are put together.
- a guide rail is understood to mean a complete guide rail and/or a guide rail piece, depending on the context.
- EP 0397064 B1 describes an elevator system with an elevator shaft with a first travel path for a first elevator car of the elevator system and a second travel path for a second elevator car of the elevator system.
- the first travel path and the second travel path are arranged next to one another in a width direction of the elevator shaft.
- a plurality of first intermediate supports are arranged, which are spaced apart from one another in the vertical direction and run in a depth direction of the elevator shaft that runs at right angles to the width direction.
- the first elevator car is connected to a first counterweight via a first support means and the second elevator car is connected to a second counterweight of the elevator system via a second support means.
- the elevator shaft has a third travel path for the first counterweight and a fourth travel path for the second counterweight.
- the third travel path for the first counterweight is between the first travel path for the first elevator car and a in the depth direction adjacent to the first travel path for the first elevator car.
- the fourth travel path for the second counterweight is arranged between the second travel path for the second elevator car and the first intermediate supports.
- JPS60f78f77A and CNf07804767A also describe elevator systems, each with an elevator shaft, a first travel path for a first elevator car, a second travel path for a second elevator car, a third travel path for a first counterweight and a fourth travel path for a second counterweight.
- JPS6481782A describes a generic elevator system.
- the elevator system has an elevator shaft with a first travel path for a first elevator car of the elevator system and a second travel path for a second elevator car of the elevator system.
- the first travel path and the second travel path are arranged next to one another in a width direction of the elevator shaft.
- a plurality of first intermediate supports are arranged, which are spaced apart from one another in the vertical direction and run in a depth direction of the elevator shaft that runs at right angles to the width direction.
- a plurality of second intermediate supports are arranged, which are spaced apart from one another in the vertical direction and run in the depth direction of the elevator shaft.
- the second intermediate supports are arranged at a distance from the first intermediate supports in the width direction. Between the first intermediate supports and the second intermediate supports, a third travel path for a first counterweight of the elevator system, which is connected to the first elevator car via a first support means, and a fourth travel path for a second counterweight of the elevator system, which is connected to the second elevator car via a second support means, are arranged.
- the first intermediate supports and the second intermediate supports have an elongated shape and are supported on opposite shaft walls of the elevator shaft. According to the invention, the third travel path for the first counterweight and the fourth travel path for the second counterweight are arranged next to one another in the width direction of the elevator shaft.
- the first travel path of the first elevator car is arranged next to the third travel path of the first counterweight and the second travel path of the second elevator car is arranged next to the fourth travel path of the second counterweight.
- the first counterweight advantageously does not travel directly past the second elevator car and the second counterweight does not travel directly past the first elevator car.
- the third travel path is therefore not directly adjacent to the second travel path and the fourth travel path is not directly adjacent to the first travel path. This means that there is no risk of a fitter or service technician in one of the two elevator cars being endangered by the counterweight of the other elevator car. This also results in a less complex route for the two support means.
- the first travel path of the first elevator car and the second travel path of the second elevator car are each separated from the adjacent travel path of a counterweight by a protective element.
- the protective element can be designed, for example, as a protective wall in the form of a sheet metal or a Plexiglas wall, as a grid or as a net stretched in a frame, for example a textile net or a wire net.
- the protective element extends in the depth direction along the first or second travel path for the first or second elevator car. This protects a fitter or service technician located on the roof of an elevator car or on the floor of the elevator shaft from a collision with a counterweight.
- the protective elements mentioned prevent in particular the fitter or service technician from bending out of the first or second travel path into the adjacent travel path of a counterweight.
- the protective element does not have to extend over the entire height of the elevator shaft.
- a first protective element is arranged in particular on the floor of the elevator shaft. In particular, it has a height that is at least as great as the height of the counterweight arranged in the adjacent travel path.
- a second protective element is arranged in particular at the middle height of the elevator shaft, i.e. where the elevator car and the associated counterweight pass each other.
- the arrangement of the travel paths for the counterweights between the first and second intermediate supports takes up very little space in the cross-section of the elevator shaft. This means that an elevator system with such an elevator shaft can have elevator cabins with particularly large cross-sections and thus base areas, or with a given cross-section and thus base area of the elevator cabins, the elevator shaft can have a particularly small cross-section.
- Guide rails can be attached to the first and second intermediate supports, at least indirectly, to guide the first and second counterweights, as well as the first and second elevator cabins, during movement in the elevator shaft.
- the first and second intermediate supports thus fulfil several tasks, so that further components can be omitted.
- the elevator shaft can be built using little material, in particular little metal. This enables the elevator shaft to be built cost-effectively and in a resource-saving manner.
- the elevator shaft is limited in particular by solid shaft walls, which can be made of concrete or wood, for example. However, it is also possible that the elevator shaft is limited by a supporting structure, particularly made of metal.
- the elevator shaft and thus also the travel paths for the independently movable elevator cabins and the counterweights of the elevator shaft connected to the elevator cabins run vertically in particular, although small deviations from the vertical are possible.
- the individual travel paths are therefore each designed as mainly cuboid-shaped, non-overlapping spaces in which an elevator cabin or a counterweight can be moved vertically.
- a vertical extension of the elevator shaft can be referred to as a height of the elevator shaft.
- a vertical position within the elevator shaft can be referred to as a height in the elevator shaft.
- the elevator shaft has, in particular, a mainly cuboid basic shape. It therefore has a height extending in the vertical direction, a width extending in the width direction and a depth extending in the depth direction.
- the elevator shaft has in particular shaft openings at different heights, with a shaft opening usually being assigned to a floor of the building containing the elevator shaft.
- a shaft opening usually being assigned to a floor of the building containing the elevator shaft.
- Shaft openings assigned to a floor are arranged next to one another, in particular in the width direction of the elevator shaft. It is also possible for an elevator car to have two opposite car doors, so that at least on one floor the elevator shaft also has opposite shaft openings.
- the elevator shaft may also have more than two travel paths for elevator cars and more than two travel paths for counterweights.
- the first and second intermediate supports run in the depth direction, whereby the depth direction does not have to run exactly at right angles to the width direction; a small deviation is possible.
- the first and second intermediate supports also run horizontally in particular.
- a first intermediate support and a corresponding second intermediate support are arranged in pairs at different heights.
- a first intermediate support and a corresponding second intermediate support have a distance of between 70 and 100 cm, for example.
- Two first or second intermediate supports arranged vertically one above the other have a distance of between 200 and 400 cm, for example.
- the first and second intermediate supports have an elongated shape and support on opposite shaft walls.
- shaft walls In the case of concrete shaft walls, for example, they can be cast in when the shaft walls are being poured. It is also possible for the shaft walls to be cast first and the intermediate supports then to be attached, for example screwed, to the shaft walls.
- the shaft walls can also have ledges or niches on which the intermediate supports can rest from above. It is also possible for only one of the two intermediate supports of a first and a corresponding second intermediate support to rest on opposite shaft walls and for the other intermediate support to be attached to the intermediate support resting on the shaft walls.
- the first and second intermediate supports are designed in particular as metal supports, for example as hollow profiles with a rectangular cross-section, T-beams or double-T-beams, with optional attachments.
- the intermediate supports in particular have fastening options for fastening guide rails of the elevator system to the intermediate supports.
- the fastening options can be designed, for example, as elongated holes or threaded pins.
- the arrangement of the third travel path for the first counterweight and the fourth travel path between the first and second intermediate supports results in the first intermediate supports and the second intermediate supports being designed and arranged such that the first and second counterweights can be displaced vertically between them.
- a first intermediate support and a corresponding second intermediate support of the elevator shaft run parallel to one another and at the same height in the elevator shaft.
- guide rails of the elevator system are attached to the intermediate supports. Due to the aforementioned arrangement of the intermediate supports, an installer on an installation platform can attach guide rails to a first and a second intermediate support during installation of the elevator system without having to change the position of the installation platform in the vertical direction. This enables a particularly simple, quick and therefore cost-effective installation of the elevator system.
- the first intermediate carrier and the corresponding second intermediate beam of the elevator shaft is connected to a cross beam.
- Components of the elevator system, in particular guide rails, can also be attached to the cross beam.
- the cross beam can have corresponding fastening options like the intermediate beams. The cross beam thus enables particularly simple, quick and therefore cost-effective installation of the elevator system.
- the cross beam can contribute to a high level of stability of a combination of a first intermediate beam and a corresponding second intermediate beam.
- the cross member runs in particular in the width direction of the elevator shaft and horizontally with intermediate supports arranged parallel and at the same height. More than one cross member, for example two or three cross members, can be arranged between a first intermediate support and a corresponding second intermediate support. A cross member can be arranged, for example, between the third travel path for the first counterweight and the fourth travel path for the second counterweight. It is also possible that alternatively or additionally cross members are arranged between the third and/or fourth travel path and a wall delimiting the elevator shaft. This means that guide rails for the first and/or second counterweight can be attached to a cross member and do not have to be attached to the aforementioned wall of the elevator shaft. Attaching to a cross member is usually simpler, faster and therefore less expensive than to a wall of the elevator shaft, especially if this is made of concrete.
- a first intermediate support and a corresponding second intermediate support of the elevator shaft run at the same height in the elevator shaft in the elevator system.
- the first intermediate support and the corresponding second intermediate support are connected to a cross beam and a guide rail for the first counterweight and/or the second counterweight is attached to the cross beam.

- the second support means 134 runs over a second drive pulley 138 arranged above the second elevator car 130 and a second deflection pulley 140 arranged above the second counterweight 136.
- the second drive pulley 138 can be driven by a second drive machine (not shown), whereby the second support means 134 and thus the second elevator car 130 and the second counterweight 136 can be displaced vertically in the elevator shaft 112.
- the two drive machines can be controlled independently of each other by an elevator control system (not shown), so that the first elevator car 116 and the second elevator car 130 can be moved independently of each other in the elevator shaft 112.
- a third travel path 142 for the first counterweight 120 and a fourth travel path 144 for the second counterweight 136 are arranged in the travel path 126 for the second elevator car 130, with the third travel path 142 being arranged to the left of the fourth travel path 144 in Fig. 1.
- the third travel path 142 and the fourth travel path 144 are thus arranged next to one another in the width direction 32.
- the third travel path 142 is thus arranged next to the first travel path 114 in the width direction 32 and the fourth travel path 144 is arranged next to the second travel path 126 in the width direction 32.
