Description

  The present invention relates to an elevator apparatus for a building having at least one transfer floor. The invention is defined at the beginning of the independent claims.

  The modern elevator concept for buildings with more than 30 floors has a transfer floor that is in charge by the elevator system. Such an elevator apparatus comprises a group consisting of at least two elevators. The first elevator is in charge of the transfer floor directly from the entrance lobby, i.e. passengers are delivered relatively quickly and roughly from the entrance lobby to the various transfer floors by high-speed elevator. The second elevator delivers passengers from the transfer floor to their destination floor.

  Elevators typically include an elevator car that can move vertically within the hoistway, and the elevator car accepts passengers for transport to the desired floor of the building. To be able to accomplish this task, elevators typically have at least the following elevator components: That is, a drive unit including a motor and a drive pulley, a deflection roller, a pulling means, a counterweight, and a pair of guide rails for guiding an elevator car and a counterweight.

  In this case, the motor generates the force necessary to carry the passengers present in the elevator car. The electric motor usually takes on this function. The motor drives the drive pulley directly or indirectly, and the drive pulley is in frictional contact with the pulling means. The pulling means may be a belt or a cable. The pulling means function for suspending and transporting the elevator car and the counterweight, and both the elevator car and the counterweight are suspended so that their gravitational force acts in the opposite direction along the pulling means. It has been. As a result, the force in the direction of gravity that the drive unit must overcome is thereby greatly reduced. Furthermore, since the contact force between the pulling means and the driving pulley is increased, a larger driving moment can be transmitted to the pulling means by the driving pulley. The pulling means is guided by a deflection roller.

  Optimal use of hoistway volume is becoming increasingly important in elevator construction. In particular, in highly utilized high-rise buildings, it is desirable to handle passenger flow as efficiently as possible in a given hoistway volume. This objective can be achieved, firstly, by optimally arranging the components of the elevator to save space, creating a space for a larger elevator car, and secondly, one This can be achieved by an elevator concept that allows a plurality of separate and independent elevator cars to move vertically in the hoistway.

  EP 1526103 shows an elevator installation comprising at least two elevators in a building divided into zones. In this case, the zone comprises a predetermined number of floors served by the elevator. Zones are assigned to each elevator. In order to move from one zone to another, a transfer floor is provided. At least one of the elevators has two elevator cages that are vertically and vertically movable relative to each other in two cage guide rails. This configuration of two fetches or carry cages is to help prevent unnecessary waiting times at the transfer floor.

An elevator with at least two elevator cages arranged one above the other in the same hoistway is known from EP1488903. Each elevator car has its own drive and its own counterweight. Drives are disposed near the first and second walls of the hoistway, and the counterweight is also below the associated drive unit at the drive or holding cable near the first and second walls of the hoistway. It is suspended by each. The shaft of the drive pulley of the drive unit is disposed at right angles to the first and second walls of the hoistway. Two elevator cars that can be moved independently of each other guarantee a high transport capacity. By disposing the drive unit in the hoistway near the first or second wall, a separate engine room is unnecessary, and a drive element is compactly arranged above the hoistway to save space. We are trying to save.
EP 1526103 Specification European Patent No. 1489033

  The object of the present invention is to further improve the transport capacity of an elevator system for a given hoistway cross-section in a building with zoning and at least one transfer floor.

  The above object is achieved according to the invention by the definition of the independent claims.

  The elevator installation according to the invention is located in a building with at least two elevators, the building being divided into building zones, each elevator having at least one elevator car. Each elevator car can be moved independently within its car zone by its drive. Furthermore, each cage zone has at least one transfer floor. The first elevator has at least three elevator cars arranged vertically in the hoistway. At least three cage zones are assigned to the building zone.

  Thanks to at least three elevator cages that can be moved independently of one another in the elevator, the elevator installation has a greatly improved transport capacity. Therefore, the waiting time at the transfer floor is further shortened, and the occurrence of a queue is greatly avoided.

  Advantageously, the at least one elevator car of the second elevator is a multi-cage comprising at least two cages arranged vertically one above the other. Because these two cages are physically connected and can only move together, they are associated with the same cage zone.

  The advantage of an elevator system with a double cage is that the available cage volume in the elevator car is doubled. Therefore, it is possible to carry up to twice as many passengers by one movement.

  Advantageously, the multi-cage is responsible for at least two transfer floors arranged one above the other.

  The advantage of the elevator apparatus is that the waiting time at each transfer floor can be further shortened when the transfer floor is doubled. The transfer floor has a space for transfer or waiting for transfer. If the number of such transfer spaces is doubled, passengers will be doubled in volume even if the transfers are made without substantial interference and the waiting time should occur despite improved transport capacity. The waiting space can be used. Therefore, staying on the transfer floor or in the transfer or waiting space is more comfortable in all cases.

  Advantageously, at least three elevator cars of the first elevator have a central and two neighboring elevator cars. In this case, the central elevator car can move independently in the central cage zone, and the two adjacent elevator cars can move independently in the two adjacent cage zones. It is further advantageous if the central cage zone overlaps the adjacent cage zone.

  The advantage of an elevator system with such overlapping cage zones is that passengers can transfer from a central cage zone to an adjacent cage zone at any desired floor located in the overlapping zone of the cage zones. is there. Thereby, it becomes possible for a passenger to guide more flexibly. Furthermore, since the floor located in the overlapping area of the car zones is handled by the two elevator cars, the transport capacity of the elevator apparatus is improved.

  Advantageously, at least three drives associated with the elevator car can be moved past the elevator car.

  The elevator system has the advantage that the drive can be arranged in a hoistway in a space-saving and flexible manner without interfering with the elevator car.

  Advantageously, at least three drives associated with the elevator car are arranged on the first wall of the hoistway or on the second wall opposite the hoistway.

  The advantage of the elevator system is that the drive is located between the elevator car and the first and second walls of the hoistway. Thereby, it is possible to save the space above the hoistway or the pit where the drive unit is normally arranged.

  Advantageously, the drive part of the central elevator car is arranged on the first wall of the hoistway and the two drive parts of the adjacent elevator car are arranged on the second wall on the opposite side of the hoistway.

  The advantage of the elevator system is that it can be arranged flexibly and concisely in the same hoistway, even with a large number of drives and associated elevator cages. On the other hand, in the conventional arrangement in which the drive unit is placed above the hoistway, the number of drive units that can be installed is limited by the available space above the hoistway. Further, in the conventional arrangement in which such a driving unit is placed on the upper part of the hoistway, it is likely to approach the limit to guide the pulling element without interference.

  The invention will be clarified and explained in more detail below by means of exemplary embodiments and drawings.

  The hoistway is a space defined by six boundary surfaces, in which one or more elevator cars can move along a movement path. Usually, four hoistway walls, a ceiling, and a floor form these six boundary surfaces. However, it is also conceivable that the upper or lower movement path restriction presents a boundary surface. This definition of hoistway can be expanded in the sense that a plurality of movement paths along which one or more elevator cars can move along each is also arranged in the hoistway adjacent to each other in the horizontal direction.

  FIG. 1 shows an elevator comprising at least three elevator cages 7a, 7b, 7c, each of which has its own drive A1, A2, A3 and is movable independently of one another in the vertical direction. In this case, the central elevator car 7a is disposed between two adjacent elevator cars 7b and 7c disposed respectively below and above the central elevator car 7a.

  Related drive parts A1, A2, A3 are arranged laterally on the first and second walls of the hoistway. The first and second walls of the hoistway are walls facing each other of the hoistway and do not have hoistway doors. The drive part A1 of the central elevator car 7a is located on the first wall of the hoistway, and the two drive parts A2, A3 of the adjacent elevator car 7b, 7c are the second part on the opposite side of the hoistway. Located on the wall. In this case, the drive units A1, A2, and A3 are alternately arranged on opposing walls of the hoistway. Further drives (not shown) of the further elevator car are arranged alternately on the first and second walls of the hoistway, corresponding to the alternating order of the drives.

  The drive units A1, A2, and A3 are arranged at three different hoistway heights in FIG. 1, and drive the adjacent elevator cages 7b and 7c above or below the drive unit A1 of the central elevator car 7a. Portions A2 and A3 are located. In general, the vertical distance between the central drive A1 and the adjacent drives A2, A3 is the height of at least one cage.

  However, it is also possible to arrange the two drive units at the same hoistway height. For example, the drive part A1 of the central elevator car 7a can be arranged on the first wall of the hoistway, and the drive part A3 of the adjacent upper elevator car 7c can be placed on the opposite side of the hoistway at the same hoistway height. Can be placed on two walls. The advantage of this arrangement is that the two drive parts A1, A3 can be easily maintained. In particular, they can be maintained from a common platform.

  The drive units A1, A2, A3 have motors M1, M2, M3 and drive pulleys 1a, 1b, 1c, respectively. Motors M1, M2, and M3 are arranged to be operatively connected to the drive pulleys 1a, 1b, and 1c, and the pulling means Z1, Z2, and Z3 are driven by the drive pulleys 1a, 1b, and 1c. The drive pulleys 1a, 1b, 1c are designed to be suitable for receiving one or more tensioning means Z1, Z2, Z3. The pulling means Z1, Z2, Z3 are preferably belts such as belts with wedge ribs provided on one side with ribs which engage one or more recesses on the drive pulley side. Similarly, belt variants such as smooth belts and belts having teeth on one or both sides can also be used with the corresponding drive pulleys 1a, 1b, 1c. In addition, various types of cables such as a single cable, a double cable, or multiple cables can be used. The pulling means Z1, Z2, Z3 comprise steel wires or stranded wires made of aramid or Vectran (registered trademark).

  The at least three elevator cars 7a, 7b, 7c and the three counterweights 12a, 12b, 12c are suspended from the pulling means Z1, Z2, Z3 in the form of pulleys. In this case, the elevator cages 7a, 7b, 7c connect at least one first deflection roller 2a, 2b, 2c and at least one second deflection roller 3a, 3b, 3c to the lower part of the elevator car 7a, 7b, 7c. Have fixed to the area. These deflecting rollers 2a, 2b, 2c, 3a, 3b, 3c have one or more grooves on the outer periphery that can accept one or more pulling means Z1, Z2, Z3. Accordingly, the deflection rollers 2a, 2b, 2c, 3a, 3b, and 3c are suitable for guiding the pulling means Z1, Z2, and Z3, and are in contact with the pulling means Z1, Z2, and Z3. In this way, the elevator cars 7a, 7b, 7c are preferably suspended as a lower pulley device.

  In any embodiment, the deflection rollers 2a, 2b, 2c, 3a, 3b, 3c are arranged in the upper region of the elevator cars 7a, 7b, 7c. In this case, the elevator car 7a, 7b, 7c is suspended as an upper pulley device corresponding to the above description.

  Similarly to the deflection rollers 2a, 2b, 2c, 3a, 3b, and 3c, the upper region of the counterweights 12a, 12b, and 12c also has a third suitable for receiving one or more pulling means Z1, Z2, and Z3. Deflection rollers 4a, 4b, 4c are arranged. Accordingly, the counterweights 12a, 12b, 12c are preferably suspended as upper pulley devices below the associated driving parts A1, A2, A3 in the third deflection rollers 4a, 4b, 4c.

  The pulling means Z1, Z2, Z3 from the first fixed points 5a, 5b, 5c to the first, second and third deflecting rollers 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c and From the first wall of the hoistway to the second wall of the hoistway to the second fixed points 6a, 6b, 6c via the drive pulleys 1a, 1b, 1c. In this case, the first fixed points 5a, 5b, 5c are arranged at approximately the same hoistway height in the vicinity of the first or second wall of the hoistway on the opposite side of the associated drive part A1, A2, A3. Has been. The second fixing points 6a, 6b, 6c are arranged in the vicinity of the associated driving parts A1, A2, A3 on the second or first wall on the opposite side of the hoistway.

  The pulling means Z1, Z2, Z3 extend downward from the first fixing points 5a, 5b, 5c along the first or second wall of the hoistway to the second deflection rollers 3a, 3b, 3c, and The second deflection rollers 3a, 3b, and 3c travel from the outside to the inside at an angle of 90 °, and continue to the first deflection rollers 2a, 2b, and 2c. The pulling means Z1, Z2, Z3 travel around the first deflecting rollers 2a, 2b, 2c from the inside to the outside over about 90 °, and then drive pulleys upward along the elevator cars 7a, 7b, 7c. The drive pulleys 1a, 1b, and 1c are wound over about 150 ° from the inside to the outside. The winding angle can be set in the range of 90 to 180 ° according to the setting of the arbitrary setting pulleys 13a, 13b, and 13c. Thereafter, the pulling means Z1, Z2, Z3 are guided downwardly along the second or first wall of the hoistway to the third deflection pulleys 4a, 4b, 4c, and about 180 ° from the outside to the inside. It goes around the third deflection pulleys 4a, 4b and 4c, and is again guided upward along the second or first wall of the hoistway to the second fixed points 6a, 6b and 6c.

  As described above, the setting pulleys 13a, 13b, and 13c are optional components of the drive units A1, A2, and A3. In order to transmit a desired tension from the driving pulleys 1a, 1b, 1c to the pulling means A1, A2, A3 by the setting pulleys 13a, 13b, 13c, the pulling means Z1, Z2, Z3 in the driving pulleys 1a, 1b, 1c. Can be set, i.e., increased or decreased. Furthermore, depending on the separation of the respective setting pulleys 13a, 13b, 13c from the drive pulleys 1a, 1b, 1c, from the drive parts A1, A2, A3, from the counterweights 12a, 12b, 12c, or from the elevator cars 7a, 7b. , 7c, the separation of the pulling means Z1, Z2, Z3 can be set. In this way, guidance without interference of the pulling means Z1, Z2, Z3 in the hoistway is ensured between the drive pulleys 1a, 1b, 1c and the first deflection rollers 2a, 2b, 2c.

  Elevator cages 7a, 7b, 7c and their associated drive parts A1, A2, A3, drive pulleys 1a, 1b, 1c, deflection rollers 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c, arbitrary The setting pulleys 13a, 13b, 13c, the counterweights 12a, 12b, 12c, the pulling means Z1, Z2, Z3 and the fixing points 5a, 5b, 5c, 6a, 6b, 6c form an elevator unit. Accordingly, FIG. 1 shows an elevator having three elevator units, ie three elevator units form a triple group 14.

  Starting from the central elevator unit with the elevator car 7a, the adjacent lower elevator unit with the elevator car 7b and the adjacent upper elevator unit with the elevator car 7c are each arranged in a mirror image with respect to the central elevator unit. ing. Accordingly, the drive units A1, A2, A3 of the elevator unit are located on the first or second wall of the hoistway facing each other, and the associated drive pulleys 1a, 1b of the adjacent elevator cages 7a, 7b, 7c. 1c, deflection rollers 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c, setting pulleys 13a, 13b, 13c, counterweights 12a, 12b, 12c, pulling means Z1, Z2, Z3, and fixing points 5a, 5b, 5c, 6a, 6b, and 6c are also arranged in a mirror image. This law of mirror image placement of the central and adjacent elevator units applies to any desired number of elevator units installed in the hoistway.

  A further feature of the elevator unit arrangement is that the associated drives A1, A2, A3 and the first fixing points 5a, 5b, 5c are approximately level on the opposing first and second walls of the hoistway. It is in the point where it is arranged. The hoistway height predetermined by the fixed points 5a, 5b, 5c and the drive parts A1, A2, A3 is simultaneously the highest point that the corresponding elevator car 7a, 7b, 7c can reach. This is because the pulling means of the illustrated embodiment cannot lift the suspension points of the elevator cages 7a, 7b, 7c higher than the height of the drive pulleys 1a, 1b, 1c. The arrangement of the drives A1, A2, A3 and the first fixing points 5a, 5b, 5c of the central and adjacent elevator cars 7a, 7b, 7c is usually carried out at different hoistway heights. Thus, the elevator cars 7a, 7b, 7c can only reach different maximum hoistway heights. In response, the central and adjacent elevator cars 7a, 7b, 7c are assigned to separate car zones in which the elevator cars 7a, 7b, 7c are movable.

  The cage zones K1, K2, K3 assigned to the elevator cars 7a, 7b, 7c are evident in FIG. From FIG. 1, it is clear that the hoistway heights of the drive parts A1, A2, A3 in the above configuration predetermine the maximum hoistway height of such cage zones K1, K2, K3. On the other hand, the minimum hoistway heights of the cage zones K1, K2, and K3 are defined by the driving portions A1, A2, and A3 of the adjacent elevator unit at the lower side and at one. In the example of the illustrated embodiment, the counterweight 12c of the adjacent upper elevator car 7c and the drive unit A2 of the adjacent lower elevator cage 7b arranged below the center weight and the adjacent elevator Due to the mirror image configuration of the unit, it is arranged on the same first or second wall of the hoistway. Therefore, the minimum hoistway height that can be reached by the counterweight 12c is limited by the drive unit A2 disposed below the same wall of the hoistway. In this way, the range of movement of the counterweight 12c between the drive unit A2 and the drive unit A3 is such that the elevator car 7c has a range of 2: 1 for simultaneous suspension of the elevator car 7c and the counterweight 12c. Zone K3 is defined.

  If this teaching is used for triplet group 14, it results in partially overlapping cage zones K1, K2, K3 where only the central and adjacent cage zones K1, K2, K3 overlap. Therefore, in a high-rise building in which a plurality of triplet groups 14 are arranged one above the other, all other floors located in the central cage zone K1 are handled by two elevator cars.

  According to FIG. 2, the elevator cars 7a, 7b, 7c are guided by two car guide rails 10.1, 10.2. The two cage guide rails 10.1, 10.2 form a connecting surface V extending almost through the center of gravity S of the two elevator cages 7a, 7b, 7c in any case. In the illustrated embodiment, the elevator cars 7a, 7b, 7c are suspended eccentrically. Here, only the arrangement configuration of two elevator units arranged directly above and below is shown. However, it will be apparent to those skilled in the art that other elevator unit pair arrangements that are directly above and below each other are similarly implemented.

  Pulling means Z1, Z2, Z3 and related guide means such as deflection rollers 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c and drive pulleys 1a, 1b, 1c (deflection rollers 4a, 4b, 4c Is not shown in FIG. 2 for the sake of clarity) In this suspension configuration, it is located on one side of the connecting surface V, ie all the above mentioned relating to the elevator cars 7a, 7b, 7c. Are located either between the third wall of the hoistway and the connection surface V or between the fourth wall of the hoistway and the connection surface V. The third or fourth wall of the hoistway refers to the wall of the hoistway having at least one hoistway door 9 of the hoistway and the wall of the hoistway facing the hoistway. The distance y between the pulling means Z1, Z2, Z3 and the connecting surface V is advantageously approximately the same. The pulling means Z1, Z2, Z3 of the elevator cars 7a, 7b, 7c are alternately arranged on one side or the other side of the connection surface V. Therefore, the moment generated by the eccentric suspension of the elevator car 7a, 7b, 7c has an opposite action. When the rated loads of the elevator cars 7a, 7b, 7c are the same and the number of the elevator cars 7a, 7b, 7c is an even number, the moment acting on the guide rails 10.1, 10.2 increases greatly.

  The counterweights 12a, 12b, 12c include two counterweight guide rails 11a. 1, 11a. 2, 11b. 1, 11b. Guided by 2. The counterweights 12a, 12b, 12c are disposed between the cage guide rails 10.1, 10.2 and the first or second wall of the hoistway on the opposing walls of the hoistway. Advantageously, the counterweights 12a, 12b, 12c are suspended from the pulling means Z1, Z2, Z3 at their centers of gravity. Since the elevator car 7a, 7b, 7c is suspended eccentrically, the counterweights 12a, 12b, 12c are shifted laterally closer to the third and fourth walls of the hoistway.

  The rotational axes of the drive pulleys 1a, 1b, 1c and the deflection rollers 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c are parallel to the first or second wall of the hoistway. In the illustrated embodiment, these components can receive four guiding means Z1, Z2, Z3 extending in parallel and guide them or drive them further in the case of the drive pulleys 1a, 1b, 1c. It is a form. The deflection rollers 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c and the drive pulleys 1a, 1b, 1c are arranged in four specially configured to accept the pulling means Z1, Z2, Z3. In the case of cables, for example designed as grooves, or in the case of belts, also designed as recessed surfaces or teeth, in the case of flat configured contact surfaces, guides Steps are provided. These four contact surfaces may be formed on a common roller-shaped body, or may be formed on four separate rollers each having a common axis of rotation.

  According to the knowledge of this embodiment, a number of possible variations for each purpose are available to those skilled in the art. That is, one to four or more independent rollers may or may not be spaced apart from each other, but can be arranged on one rotating shaft. In that case, each roller can accept one to four, depending on its design, or even more tensioning means Z1, Z2, Z3 as required.

  In the normal operation of an elevator, the elevator cars 7a, 7b, 7c are placed on the same plane as each floor at the stop position of each floor, and passenger movement from each floor to the elevator cages 7a, 7b, 7c (and vice versa). For this purpose, the cage door 8 is opened together with the hoistway door 9.

  FIG. 3 shows another suspension configuration in which the elevator cars 7a, 7b, 7c are suspended in the center. Here, only the arrangement configuration of two elevator units arranged directly above and below is shown. However, it will be apparent to those skilled in the art that other elevator unit pair arrangements that are directly above and below each other are similarly implemented.

  In this case, the pulling means Z1, Z2, and Z3 are guided from the deflection roller and the driving pulleys 1a, 1b, and 1c on both sides of the connection surface V. Thus, the suspension is advantageously configured symmetrically with respect to the connection surface V. In this case, the center of gravity of the suspension substantially matches the center of gravity S of the elevator cages 7a, 7b, 7c, so that no additional moment acts on the cage guide rails 10.1, 10.2.

  In the central suspension of the elevator cars 7a, 7b, 7c, the associated deflection rollers 2a. 1, 2a. 2, 2b. 1, 2b. 2, 3a. 1, 3a. 2, 3b. 1, 3b. 2 and drive pulley 1a. 1, 1a. 2, 1b. 1, 1b. 2 includes at least two rollers disposed on the left side and the right side of the connection surface V. Similarly, the deflection rollers 4a, 4b, and 4c of the counterweights 12a, 12b, and 12c are composed of two rollers disposed on the left and right sides of the connection surface V, but are not shown in FIG. 3 for the sake of clarity. . In this example, the deflection rollers 2a. 1, 2a. 2, 3a. 1, 3a. 2 and drive pulley 1a. 1, 1a. 2 is located at a first distance x from the connection surface V and is combined with the adjacent lower elevator car 7b. 1, 2b. 2, 3b. 1, 3b. 2 and the drive pulley 1b are located at the second interval X from the connection surface V, and the first interval x is smaller than the second interval X. Thereby, in the case of the center suspension of the elevator cars 7a, 7b, 7c, guidance without interference of the pulling means Z1, Z2, Z3 is ensured.

  Again, the counterweights 12a, 12b, 12c are between the cage guide rails 10.1, 10.2 and the first or second wall of the hoistway at their center of gravity S, with the pulling means Z1, It is advantageously suspended from Z2 and Z3. Since the elevator cars 7a, 7b, 7c are now suspended at the center, the counterweights 12a, 12b, 12c are also located in the central region of the first and second walls of the hoistway. Thanks to the central arrangement of the counterweights 12a, 12b, 12c, the free space between the lateral ends of the counterweights 12a, 12b, 12c and the third and fourth walls of the hoistway is increased. This provides a degree of design freedom for the counterweights 12a, 12b, 12c. That is, for example, to make better use of this space, thinner counterweights 12a, 12b, 12c and wider 12a, 12b, 12c can be used. For a given hoistway section, the width of the elevator cages 7a, 7b, 7c can be increased, or for a given cage size, the hoistway section can be reduced.

  The center and eccentric suspension variations shown in FIGS. 2 and 3 can be combined with the embodiments of FIGS. 5 and 6 below as desired.

  As shown in FIG. 4, the drive unit A1 includes a motor M1 (preferably an electric motor), a drive pulley 1a, and, in some cases, a winding angle of the tension means Z1 around the drive pulley 1a and the drive unit. A setting pulley 13a capable of setting the horizontal separation of the pulling means Z1 from A1 with respect to the elevator car 7a or the counterweight 12a.

  The motor M1 is positioned vertically above the drive pulley 1a. Thanks to this arrangement, the drive can be arranged in a clear projection of the counterweight 12a between the elevator car 7a and the first and second walls of the hoistway. As a result, the drive unit A1 can be moved alongside the elevator car 7a, and thus can be disposed in an unnecessary space in a normal hoistway. As a result, space can be obtained in the upper part of the hoistway and / or in the pit of the hoistway as compared with a conventional elevator without an engine room.

  According to FIG. 4, the drive part A1 is connected to the cage guide rail 10.1 and / or the counterweight guide rail 11a. 1, 11a. It is attached to a transverse member 19 fixed to 2. Further, in FIG. 4, the third deflection roller 4 a suspending the counterweight 12 a can be seen, and the elevator car 7 a can be seen behind. The example shown here is a mirror image with respect to the connection surface V by comparison with the arrangement configuration of FIG.

  In some cases, the drive unit A1 may be directly attached to the wall of the hoistway, in which case the lateral member 19 is omitted.

  FIG. 5 shows an elevator installation for a building with zoning. The building zones G1 and G2 are composed of a plurality of floors of a building arranged in a vertical direction. In that case, at least one of those floors of the building zones G1, G2 is referred to as transfer floors U1, U2. It is normal to move from one building zone G1 to another building zone G2 by a feed elevator that stops only at the transfer floor. Here, the feed elevator is designed as a high-speed elevator. The remaining floors assigned to the building zones G1, G2 are delimited by the floors in charge by the leaving elevators 14.1, 14.2. The leaving elevators 14.1 and 14.2 have a role of finely delivering passengers from the transfer floors U1 and U2 to their destination floor.

  Here, the building is divided into two building zones G1, G2. Each of these building zones G1, G2 is assigned a triple child group 14.1, 14.2. The triple child groups 14.1, 14.2 are assigned to the building zones G1, G2 to which they are assigned. Responsible for the floor only. The elevator apparatus has three elevators arranged in two hoistways 15.1, 15.2. In the first hoistway 15.1 there are two triple groups 14.1, 14.2 arranged one above the other, and two triple groups 14.1, 14.2. , Six elevator units, six elevator cages, and associated cage zones K1.1, K1.2, K1.3, K2.1, K2.2, K2.3. Therefore, the movement from the first building zone G1 to the second building zone G2 is inevitably performed by the elevator of the second hoistway 15.2, and the transfer floors U1.1, U1. 2 to the transfer floors U2.1 and U2.2 in the building zone G2. The two triplets 14.1, 14.2 are responsible for transporting passengers from the transfer floors U2.1, U2.2 to the respective floors of the corresponding building zones G1, G2, and any of the building zones G1, G2 Responsible for transporting passengers between the two floors. In this way, more efficient channeled transport is achieved for passengers in the building.

  In some cases, the first hoistway 15.1 can be further divided into two separate and independent hoistways, each with a respective elevator. The hoistway heights of these separate hoistways are substantially matched to the height of the corresponding building zones G1, G2. The advantage of such a separate hoistway is that it eliminates the chimney effect and thus eliminates the undesirably strong hoistway drafts that can occur in higher hoistways.

  The high-speed elevator responsible for only the transfer floors U1.2, U1.1, U2.1, U2.2 moves in the second elevator hoistway 15.2. In the illustrated example, the high-speed elevator is a two-story elevator in which two cages that are arranged perpendicular to each other and can move the shaft 15.2 are fixedly connected. Such a two-story cage has two transfer floors U1.2, U. Responsible for 1.1, U2.1, U2.2.

  Each cage zone K1.1, K1.2, K1.3, K2.1, K2.2, K2.3 of each building zone G1, G2 has at least one transfer floor U1.2, U1.1, U2.1, U2.2. As an example, in the following configuration, the transfer floors U2.1 and U2.2 of the two-story elevator are located in the central area of the building zone G2, and the lower transfer floor U2.2 is below the two-story cage. Side cage and triple child group 14.1 in the middle and adjacent lower elevator cage, correspondingly the upper transfer floor U2.1 is the upper cage and triple child group of the two-storey cage 14.2 resulting in an upper building zone G2 which is served by the central and adjacent upper elevator car. Thus, passengers whose destination floor is in the central cage zone K1.2 can always use the two elevator cars of the triple child group 14.2 for movement there.

  Adjacent cage zones K2.2, K3.2 preferably each comprise a respective half of the floor of the building zone, while the central cage zone K1.2 is preferably assigned to building zone G2. There are two less floors than the number of floors given. Therefore, the central elevator car can take charge of all the intermediate floors of the building zone G2 in addition to the two boundary floors. The central elevator car moves past the upper or lower adjacent car, each responsible for at least one boundary floor of the building zone G2, since the elevator cars of the triplet group 14.2 are stacked vertically. I can't.

  The central cage zone K1.2 comprises two transfer floors U2.1, U2.2 if it is the smallest size. In this case, the center elevator car of the triplet group 14.2 carries passengers from the upper transfer floor U2.1 to the lower transfer floor U2.2 and vice versa. The function of the escalator 16 is taken over in the zone G2. At this time, the two transfer floors U2.1 and U2.2 are the only floors in charge of the two elevator cars of the triple child group 14.2 in the building zone G2.

  On the other hand, if the central car zone K1.2 expands to the maximum extent, the two boundary floors of the building zone G2 are responsible only by the adjacent lower or upper elevator car of the triplet group 14.2. Left as the only floor to be. All the other floors are assigned by two elevator cars in charge when the central car zone K1.2 is maximized.

  Cage zones K1.1, K. in building zone G1. 2.1, K3.1, the associated elevator units, and the arrangements of the transfer floors U1.1, U1.2 substantially correspond to the arrangement of these components in the building zone G2. A more important additional aspect relates to the transfer floors U1.1, U1.2 of the lower building zone G1.

  The two transfer floors U1.1 and U1.2 in the lower building zone G1 are connected by an escalator 16. Escalators are often used in building lobbies. The lobby of a building is the floor where passengers enter the building and leave again, and is therefore the floor where many passengers enter and exit. For example, if the lower transfer floor U1.2 is now a building lobby, the incoming passengers can now quickly move to the upper transfer floor U1.1 as needed due to the large transport capacity of the roller escalator 16 now. You can pass through or quickly pass from here to the building lobby when you leave the building. Depending on the type and positioning of the building, the building lobby can basically be located on any floor of the building. In that case, the lobby of the building is usually served by at least one high-speed elevator of the second hoistway 15.2.

  FIG. 6 shows two further building zones G3, G4 and associated triplet groups 14.3, 14.4 as cage zones K1.3, K2.3, K3.3, K1.4, K2.4, The building with K3.4 and associated transfer floors U3.1, U3.2, U4.1, U4.2 is shown. In this way, the required number of triplet groups 14 can be arranged perpendicular to each other.

  The present invention is not limited to the illustrated embodiment. With knowledge of the present invention, it is obvious to those skilled in the art to optimize various parameters for a particular form of building. Instead of a two-storey cage, it is also possible to operate a plurality of cages or a single independent cage, or a multi-cage with three or more cages connected together in the second hoistway 15.2. is there. Furthermore, the number of floors allocated to the building zone G can be freely selected. Moreover, the building zone G does not need to have the same number of floors, and the number may be different for each building zone. Furthermore, it is not always necessary to assign only the triplet group 14 to the building zone G. That is, a group of four, five, or six children may be assigned to the building zone G. The cabin zones do not necessarily have to be configured symmetrically, for example in a triplet group. Depending on the position of the drive and the transfer floor, these cage zones K can be freely adapted to specific building conditions. Finally, the transfer floor U can also be arranged freely with respect to number and position in the building zone G, depending on the number of cages K or multi-cage cages.

  The following simple calculations show that a significant improvement in transport capacity can be achieved thanks to the present invention. For example, for a building zone G2 having 10 floors, according to the state of the art, each of the two elevator car is responsible for 9 floors, i.e. each elevator car is weighted for each floor by the number of floors it is responsible for. Which has a transport factor of 1.9, which represents an indicator of the transport performance of the elevator car on a particular floor. This gives a transport coefficient of 1/9 for each of the two boundary floors, each served by only one elevator car, giving 2 // for the 8 floors in the central area where the two car zones overlap. A transport coefficient of 9 is given.

  According to the present invention, adjacent cage zones K2.2 and K3.2 are responsible for the upper five floors and the lower five floors, respectively, and the central cage zone K1.2 is responsible for the eight floors. To do. From this, for the region where the cage zones overlap, a transport coefficient of 1/5 + 1/8, or 13/40, is provided, and for the boundary floor, a transport coefficient of 1/5 is provided.

  This simple calculation example shows that for all the floors of the building zone G2, there is a significant improvement in transport capacity. The increase in transport capacity for the two boundary floors is even more than proportional. Furthermore, it can easily be seen that this increase in transport capacity also applies to the number of floors in a building zone different from ten.
