State of the art

Skyscrapers and buildings with a large number of floors require complex elevator systems in order to manage all transport processes as effectively as possible and to be able to transport individual passengers to their destination floor as quickly as possible without long waiting times.

So-called shaft-changing multi-cabin systems, such as those marketed by the applicant as MULTl® elevator systems and described, for example, in DE 10 2014 224 323 A1, have proven particularly effective. A shaft changing multi-car system comprises a plurality of cars that can be moved in a group of elevator shafts. The cabs can not only be moved back and forth vertically in the individual elevator shafts, but also horizontally between the individual elevator shafts. For example, several such shaft changing can be in buildings

Multi-cabin systems can be used independently for different areas or zones of the building. A first shaft changing

Multi-cabin system can serve as floors 1 to 10, a second shaft-changing multi-cabin system can serve floors 11 to 20, a third system floors 21 to 30, etc.

The present invention seeks to improve the effectiveness of elevator systems.

Disclosure of the invention

According to the invention, an elevator system and a method for operating such an elevator system with the features of the independent

Claims proposed. Advantageous embodiments are the subject of the subclaims and the following description. Advantages and preferred configurations of the method according to the invention and of the

elevator system according to the invention result from the present

Description accordingly.

A building having the elevator system with at least a number o of floors comprises an m th floor, an n th floor above the m th floor and an o th floor above the n th floor. At least one further floor lies in particular between the m th floor and the n th floor. In particular, at least one further floor lies between the n th floor and the o th floor

Floor. A number of in each case expediently lies between the mth and the nth and between the nth and the oth floors

Floors, in particular at least between five and ten

Floors. The elevator system has at least one first elevator shaft, which extends between the m-th floor and the o-th floor, and at least one second elevator shaft, which extends at least between the n-th floor and the o-th floor. Furthermore, the elevator system comprises cars that can switch between the nth floor and the oth floor between the at least one first elevator shaft and the at least one second elevator shaft.

The at least one first elevator shaft and the at least one second elevator shaft expediently form a subsystem or a local group between the nth and oth floors. In this subsystem, the cabins are used, in particular, to carry out transport operations between the nth and oth floors, or the cabins

Hold stops are expediently carried out on floors lying between this nth and oth floor. For this purpose, the cars in the subsystem can switch between the different elevator shafts in order to be able to move to individual floors as effectively and quickly as possible. Within the scope of the present method, cars in the at least one first elevator shaft on at least one floor located between the m-th floor and the n-th floor do not make any stop stops in the at least one first elevator shaft and in the at least one second elevator shaft between the n- On the third and third floors, cabins stop at any floor. In particular, the number of floors can thus be between the mth

Floor and the subsystem are limited in which cabins

Stop stops are allowed to be carried out, so that cars can be moved quickly in the at least one first elevator shaft between the m-th floor and the subsystem and to avoid the formation of jams in the subsystem In principle, stops may be made between the nth and oth floors, in particular on all floors, depending on current needs.

The invention provides a possibility of quickly transporting a large number of cars from the m-th floor to the subsystem and there to different target floors and, conversely, of quickly transporting a large number of cars from different starting floors in the subsystem to the m- to move to the third floor. The at least one first elevator shaft also extends outside of this subsystem to the lower-lying mth floor and, in particular, represents an express elevator shaft between the mth floor and the nth floor, and cabins quickly between the mth floor and the subsystem to proceed. Furthermore, the at least one first elevator shaft on the nth floor merges directly into the subsystem and is also used for the subsystem between the nth and oth floors. Thus, the express elevator shaft itself becomes part of the subsystem from the nth floor. The invention provides a particularly effective way of operating the elevator system with high efficiency and with a high handling capacity. In the subsystem, in particular at least one transfer floor is provided between the nth and oth floors, in which cars can switch between the at least one first elevator shaft and the at least one second elevator shaft. At least the nth floor is expediently designed as such a transfer floor. So you can

For example, cabs which are transported from the mth floor to the subsystem in one of the first elevator shafts and are distributed to one of the remaining elevator shafts of the subsystem on the nth floor. Conversely, cars coming from the subsystem can be distributed to the first elevator shafts on the nth floor. Expediently, the oth floor can also be designed as such a transfer floor. In this case, it is particularly appropriate to use the nth or the oth floor in each case as a pure transfer floor, in which cabins none

Stop stops are allowed to move cabins between

Not to obstruct elevator shafts and to avoid traffic jams for cabins

cause which should switch between elevator shafts. In particular, the mth floor is an entrance or lobby floor of the building, in which passengers can enter or leave the building. For example, the nth floor can be at least the tenth floor of the building and the oth floor can be at least the 15th or at least the 20th floor. By means of the at least one first elevator shaft, passengers can be transported quickly from the lobby floor to the subsystem and there to their destination floor located between the nth and oth floors. Vice versa, passengers can be transported quickly to the lobby floor from a starting floor located between the nth and oth floors.

The invention is suitable, for example, for buildings in which journeys upwards are mainly carried out from an entrance floor or lobby floor and journeys downwards mainly into the entrance or lobby floor, as is the case, for example, in hotels or residential buildings. In particular, several elevator systems of this type can be provided in the building in order to serve different areas or zones of the building and to carry out transport operations there. For example, an at least one further elevator system can be provided in order to serve the floors between the m th and the n th floors. All of these systems can in particular be operated independently of one another.

It is conceivable that one or more of the elevator shafts after the top floor extend even further up to a p floor above the top floor and that cars in these further extending elevator shafts extend from the subsystem, for example, into one further subsystem lying above can be moved. For example, the Extend at least a first elevator shaft even further and connect the subsystem to a further, higher subsystem.

Advantageously, at least two first elevator shafts extend between the m-th floor and the o-th floor. Preferably, cabins on floors located between the m-th floor and the n-th floor cannot switch between the at least two first elevator shafts. In particular, cabins can therefore switch between one (m + l) -th

Do not switch floors and an (n-1) floor between the at least two first elevator shafts. Cabins in the first elevator shafts, in particular, cannot be blocked by cars changing between the first elevator shafts, so that the cars can be moved quickly between the mth floor and the subsystem. The at least two first elevator shafts thus represent in particular express elevator shafts

Moving cabins quickly between the mth floor and the subsystem. Between the mth and nth floors, the first elevator shafts can in particular be kept structurally simple, since in particular there are no relocation floors.

Cabs on the mth floor and / or the nth floor can preferably switch between the at least two first elevator shafts.

For example, if the mth floor is an entrance or lobby floor and cabins on this floor can stop

expediently a change between the first elevator shafts can also be carried out.

Cabs in the at least one first elevator shaft preferably make stop stops only on predetermined floors between the mth floor and the nth floor. If the cabins are only allowed to stop on a given floor, the distance between the cabins can be kept small. Analogous to the description above, a quick movement of cabins between the m-th floor and subsystem can be made possible.

According to a particularly preferred embodiment, cars do not stop in the at least one first elevator shaft between the m-th floor and the n-th floor. Thus, the at least one first elevator shaft between the m-th and n-th floors becomes cleaner

Express elevator shaft used to move cars as quickly as possible with little risk of jamming between the m-th floor and the subsystem. In this case, a distance between cars that are moved between the m-th floor and the n-th floor can in particular be kept as small as possible In this case, in particular, at least one further subsystem or at least one further elevator system can be provided in order to serve floors between the mth and nth floors.

According to a particularly preferred embodiment, the at least one first elevator shaft and the at least one second elevator shaft form an alternating shaft between the nth floor and the oth floor

Multi-cabin system in such a shaft changing

Multi-cabin systems are used to move between two neighboring cabins

Switch elevator shafts, especially horizontally in one

Move the connection area between these two elevator shafts or in a shaft that runs horizontally between these adjacent elevator shafts. The invention is therefore particularly suitable for a so-called MULTI® elevator system from the applicant, in which several cars can be moved independently of one another in one or more shaft sections by means of a linear motor drive. Such an elevator system with a number of cars, which can switch between shaft sections, is known, for example, from DE 10 2014 224 323 A1. Cabs are preferably moved in the at least one first elevator shaft from the mth floor up to the shaft-changing multi-car system and / or from the shaft-changing multi-car system down to the mth floor. The at least one first elevator shaft therefore particularly preferably represents an express elevator shaft between the mth and nth floors and advantageously merges directly with the shaft-changing multi-car system on the nth floor.

According to a preferred embodiment, at least two first elevator shafts extend between the m-th floor and the o-th floor.

Cabs are preferably only moved upwards in at least one elevator shaft of the at least two first elevator shafts. These elevator shafts expediently place between the mth and nth floors

Express elevator shafts to get cabins away from the m th as quickly as possible

Moving the floor to the subsystem in at least one other

Elevator shafts of the at least two first elevator shafts are preferably only moved downwards to cabs. Place these elevator shafts

in particular express elevator shafts, in order to move cabins quickly from the subsystem down to the mth floor.

Alternatively or additionally, according to an advantageous embodiment, at least two second elevator shafts extend at least between the nth floor and the oth floor. Cabs are preferably only moved upwards in at least one elevator shaft of the at least two second elevator shafts, and preferably only downwards in at least one further elevator shaft of the at least two second elevator shafts exclusively down. Preferably, depending on a number of transport processes to be carried out and / or a time of day, in which one is selected

Elevator shafts of the at least two first elevator shafts and / or in which elevator shafts of the at least two second elevator shafts, cabins are moved upwards or downwards. In particular, the predetermined direction of travel of the individual elevator shafts can thus be selected according to current needs, in particular in order to move the cabs as effectively as possible enable.

According to a preferred embodiment, at least two stops are provided on the mth floor for entering and / or leaving cabins. Thus, at least two independent entry and exit options are expediently provided, so that passengers can also enter or leave different cabins at the same time. In particular, the efficiency and handling capacity of the elevator system can be further increased. For example, these stops can be arranged next to one another and cabs can expediently be moved horizontally between the stops. The stops can, for example, also be arranged one above the other, for which purpose the mth floor can be designed, for example, as a double or multiple lobby. It is also conceivable that the at least two stops in the m-th

Floor and in at least one other floor below the mth floor are provided. This further or these further

Floors can expediently immediately below the m th

Floor.

The at least two stops are advantageously each for

Transport operations to and / or from certain floors between the nth floor and the oth floor are provided. This means that passengers can enter cabins at different stops depending on their desired destination floor in the subsystem. Accordingly, passengers can Depending on their starting floor in the subsystem, they leave cabins in different stops. In particular, the handling or conveying capacity can thus be increased even further.

Alternatively or additionally, the at least two stops are each for

Transport processes to and / or from certain elevator shafts of the at least one first elevator shaft and / or of the at least one second

Elevator shaft provided between the nth floor and the oth floor. For example, a first stop can be provided for cars that are moved in the subsystem in the at least one first elevator shaft, and a second stop for cars that are moved in the subsystem in the at least one second elevator shaft.

It goes without saying that the elevator system can also comprise further components, for example rails arranged in the individual elevator shafts or

Guide rails and drives for moving the cabins, which

can be designed in particular as linear drives.

Further advantages and refinements of the invention result from the

Description and the accompanying drawing.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own without departing from the scope of the present invention.

The invention is illustrated schematically in the drawing using an exemplary embodiment and is described below with reference to the drawing

described.

Figure description Figures 1 to 3 each show t schematically a preferred embodiment of an elevator system according to the invention, which is set up to be operated according to a preferred embodiment of a method according to the invention.

DETAILED DESCRIPTION OF THE DRAWING FIG. 1 is a preferred embodiment of an inventive one

Elevator system shown schematically and designated 100, which is set up according to a preferred embodiment of a

to be operated method according to the invention.

A building having the elevator system 100 has a floor m, for example an entrance or lobby floor, a floor n above this mth floor, e.g. a 20th floor, and and above this nth floor o, e.g. a 30th floor. It is understood that the building can have further floors, e.g. floors further above the oth floor and / or further below the mth

Floor (basement) floors.

Two first elevator shafts 111 and 112 extend between the m-th floor and the o-th floor. Two second elevator shafts 121 and 122 extend between the nth floor and the oth floor.

Cabins 150 can change between the nth floor and the oth floor between these elevator shafts 111, 112, 121, 122. In the example shown, the nth floor and the oth floor are each designed as a transfer floor for this purpose, in which the cars 150 can switch between the individual elevator shafts 111, 112, 121, 122 form in an area or a zone between the nth floor and the oth floor the elevator shafts 111, 112, 121, 122 thus a shaft changing

Multi-cabin system 132.

The first elevator shafts 111 and 112 form express elevator shafts 131 in an area or a zone between the m-th floor and the n-th floor in order to move cars 150 quickly between the entrance floor m and the shaft-changing multi-car system 132 in the n-th

On the floor, these express elevator shafts 131 go into shafts of the

shaft-changing multi-cabin system 132. Cabins 150 cannot change between the first elevator shafts 111 and 112 on floors located between the mth floor and the nth floor. In particular, cabins 150 are not allowed to make any stops in the area between the mth floor and the nth floor, which enables the cabins 150 to be moved as quickly as possible with the smallest possible distance between the cabins 150.

Furthermore, in the example shown, cars 150 in the first elevator shaft 111 and in the second elevator shaft 121 are moved exclusively upwards. In the first elevator shaft 112 and in the second elevator shaft 122, cars 150 are only moved downwards.

The first elevator shaft 111 thus forms an express elevator shaft 131 between the mth and nth floors in order to move cars 150 quickly upward from the entrance floor m into the multi-car system 132 which changes shafts. Correspondingly, the first elevator shaft 112 forms an express elevator shaft 131 between the floors m and n in order to quickly move cabins 150 downward from the multi-car system 132, which alternates with the shaft

Entrance floor m to move. FIG. 2 schematically shows an elevator system analogous to the elevator system 100 shown in FIG. 1 according to a further preferred embodiment of the invention and with 100 '. Identical reference symbols designate identical or identical elements. In the elevator system 100 ', four stops 141, 142, 143, 144 are provided horizontally next to one another in the m-th floor, in which passengers can leave and / or enter cabins 150. Furthermore, the lobby floor m is designed in such a way that cabins 150 can be moved vertically between the stops 141, 142, 143, 144 therein.

Thus, cabins 150 on the mth floor can be between the first

Elevator shafts 111 and 112 change. Cabins 150 cannot change between the first elevator shafts 111 and 112 on the floors located between the mth floor and the nth floor.

For example, the stop 141 can be provided to get from there

Carrying out operations from cabins 150 to target floors between the 20th and 25th floors. The stop 142 can be provided, for example, in order to carry out transport operations from cabins 150 to target floors between the 25th and 30th floors.

Conversely, cabins 150, which transport operations from one

Starting floor between the 20th and 25th floors from the

Execute the lobby floor m, for example, stop at the stop 143 so that passengers can leave the corresponding cabins 150 there.

The stop 144 can be provided for cabins which carry out transport operations from the starting floors located between the 25th and 30th floors into the lobby floor m. 3 shows an elevator system according to a further preferred embodiment of the invention, schematically represented by 100 ", identical reference numerals denoting identical or identical elements. In contrast to the elevator systems 100 and 100 ', the elevator system 100" has the second elevator shaft 122 between the two first elevator shafts 111 and 112 and not to the right of the elevator shaft 112.
