INSTALLATION OF ELEVATORS IN A BUILDING WITH, LIKE ViMMQ. A TRANSFER PLANT
Description The invention relates to an installation of elevators in a building with at least one transshipment plant. This invention is defined in the preamble of the independent claim. The elevators of modern design for buildings with 30 floors or more have transfer plants that are serviced by an elevator installation. An installation of elevators of this type comprises a group of at least two elevators. A first elevator serves directly to the transshipment floors from an entrance hall, that is to say the passengers are distributed to the different transshipment plants from the entrance hall approximately and in a relatively fast way by means of a high lift. performance. A second elevator carries out the "fine" distribution of the passengers from the transhipment plants to their destination plants. As a general rule, an elevator has an elevator car that can be moved vertically by a box and accommodates passengers to transport them to the desired floor of a building. In order to carry out this task, the elevator generally has at least the following elevator components: a drive with a motor and a drive pulley, deflection pulleys, traction members, a counterweight and, in each case, a pair of guide rails for guiding an elevator car and a counterweight. The engine generates the necessary power for the transport of the passengers that are in the elevator cabin. As a rule, this function is
meets an electric motor. This one directly or indirectly drives a drive pulley, which is in tribocontact with a traction organ. The traction organ can be a belt or a cable. It serves to suspend and transport the elevator car and the counterweight, which are both suspended in such a way that their weights act in opposite directions along the traction member. As a result, the resulting force which the drive has to overcome is considerably reduced. In addition, the greater support force of the traction member on the drive pulley makes it possible to transmit a greater torque of the drive pulley to the traction member. The traction member is guided by deflection pulleys. In the construction of elevators the optimum use of the volume of the box acquires more and more importance. Precisely in high-rise buildings with a high degree of utilization of the building, care must be taken to service the volume of passengers as efficiently as possible with a given capacity of the box. This objective can be achieved in the first place by an optimal arrangement of elevator components that saves space, which can be used to increase the dimensions of the elevator cars, and secondly by means of elevator concepts that make possible the vertical displacement of several independent elevator cabins in a box. Document EP 1 526 103 shows an installation of elevators with at least two elevators in a building that is divided into zones. An area comprises a certain number of floors, which are serviced by an elevator. Each elevator is assigned to an area. To get from one area to another a transfer plant is planned. At least one of the elevators has two lift cabins that, arranged vertically one above the other,
they can move around two cabin guide stanchions independently of each other. The provision of a contribution cabin and another of withdrawal of passengers is intended to help avoid unnecessary waiting times in the transshipment plants. From EP 1 489 033 an elevator is known with at least two elevator cars that are located one above the other in the same box. Each elevator car has its own drive and a counterweight of its own. The drives are arranged close to a first and a second box wall and also the counterweights are suspended in each case under the corresponding drive by means of drive or suspension cables close to a first or a second box wall. The axes of the driving pulleys of the drives are perpendicular to the first and second box walls. The two movable elevator cabins independently ensure a large transport capacity. The placement of the drives in the box close to a first or a second wall makes a separate machine room unnecessary and allows a compact arrangement of the drive elements in the upper part of the box, thus saving space. The object of the present invention is to further increase the carrying capacity of an elevator installation for a given cross section of the box in a building with zoning and at least one transfer plant. The above stated objective is achieved by the invention according to the definition of the independent claim. The installation of elevators according to the invention is in a building with as
at least two elevators, the building being divided into building zones and each elevator having at least one elevator car. Each elevator car can, by means of its own drive, be moved indepenly by an assigned car zone. In addition, each cabin area has at least one transfer plant. A first elevator has at least three elevator cars arranged vertically one above the other within a gap. At least three of the cabin areas are assigned to a building area. Thanks to the at least three cabins of a lift movable one on top of another indepenly, the installation of elevators has an ostensibly greater transport capacity. In this way, waiting times at transshipment plants are further reduced and the formation of queues is largely avoided. This, at least one, elevator car of a second elevator is advantageously a multiple car with at least two cabins arranged vertically one above the other. These two cabins are assigned to the same cabin area, since they are physically attached and therefore can only be moved together. The advantage of the installation of elevators with double cab consists in the duplication of the volume available in an elevator car. This allows transporting up to twice as many passengers per trip. The multiple cab advantageously serves at least two overlapping transshipment plants. The advantage of the installation of elevators is that a duplication of the transshipment plants makes it possible to further reduce waiting times at
different transhipment plants. The transshipment plants have a transfer room or wait for the transfer. With twice as many transshipment halls, transshipment is largely free of conflicts and, if in spite of the increased transport capacity there are still delays, passengers have twice the space for waiting. Thus, in any case a stay in the transshipment plants or the transshipment or waiting rooms becomes more pleasant. The at least three elevator cars of the first elevator advantageously have a central elevator car and two adjacent ones. The central elevator car can be moved indepenly by a central car zone and the two adjacent elevator cars can be moved indepenly by two adjacent car areas. It is further advantageous that the central cabin area overlaps the adjacent cabin areas. The advantage of installing elevators with such overlapping cab areas is that passengers on any of the floors in the overlapping area of the cab areas can transfer from a central cabin area to a cabin area adjacent. This allows a more flexible guide of the passengers. In addition, the floors located in the overlap area of the cabin areas receive service from two elevator cars, which increases the transport capacity of the elevator installation. It is advantageous that the elevator cars can exceed the at least three drives assigned to them. The installation of elevators has the advantage that the drives can be arranged saving space and with a large
flexibility in the box without conflicting with the elevator cabins. The at least three drives assigned to the elevator cars are advantageously arranged in a first box wall or a second opposite box wall. The advantage of the installation of elevators consists in the position of the drives between the elevator cars and the first and second case walls. This saves space in the upper part of the box or in the pit, where the drives are usually arranged. It is advantageous if the drive of the central elevator car is placed on the first housing wall and the two drives of the adjacent elevator cars are placed on the second opposite housing wall. The advantage of the installation of elevators consists of the flexible and simple placement of as many drives as desired and of the corresponding elevator cars in the same box. With a conventional arrangement of the drives on the top of the box, the number of installable drives is limited by the space available at the top of the box. The conflict-free guidance of the traction elements is also very limited with a conventional arrangement of the drives on the top of the box. The invention will now be explained and described in more detail by means of exemplary embodiments and drawings, which show: Figure 1: a schematic side view of an elevator arrangement of an elevator installation with three elevator cars, three drives, three drive pulleys, three traction members and several pulleys
deviation. Figure 2: a schematic view from above of an elevator arrangement of an elevator installation according to figure 1. Figure 3: a schematic top view of an optional elevator arrangement of an elevator installation according to figure 1. Figure 4 : a side view of an arrangement of the drives on crossbeams: Figure 5: a schematic side view of an installation of elevators in a building with two building zones. Figure 6: a schematic side view of an elevator installation in a building with four building zones. The gap is a space defined by six limit levels in which one or several elevator cars are moved along a driving lane. Normally, four hollow walls, a roof and a bottom constitute these six limit levels. However, it is also possible that an upper or lower limit of the driving lane represents a limit level. This definition of the gap can be extended in the sense that in a gap also several driving lanes are arranged horizontally side by side, along which one or several elevator cars can be moved in each case. Figure 1 shows an elevator with at least three elevator cars 7a, 7b, 7c each having its own drive A1, A2, A3 and can move in vertical direction independently of one another. A central elevator car 7a is arranged between two adjacent elevator cars 7b, 7c, which are respectively below and above the central elevator car 7a.
The corresponding drives A1, A2, A3 are placed laterally on a first and a second box wall. The first and the second box wall are the box walls opposite each other that do not have box doors. The drive A1 of the central elevator car 7a is placed on the first case wall and the two drives A2, A3 of the adjacent elevator cars 7b, 7c are placed on the second opposite case wall. The drives A1, A2, A3 are located alternately in opposite case walls. The additional drives of other elevator cars, not shown, are arranged alternately in the first and second i or box walls following the alternating order of the drives. In figure 1, the drives A1, A2, A3 are placed at three different box heights, the drives A2, A3 of the adjacent elevator cars 7b, 7c being placed above or below the drive A1 of the central elevator car 7a . As a rule, this distance in vertical direction 15 between a central drive A1 and an adjacent drive A2, A3 is at least equal to the height of a car. However, it is also possible to place two drives at the same box height. For example, the drive A1 of the central elevator car 7a can be arranged in a first housing wall and the drive 0 A3 of the upper adjacent elevator car 7c be arranged in the second housing wall opposite the same housing height . The advantage of this arrangement is the ease of maintenance of the two drives A1, A3, since the maintenance tasks thereof can be carried out in this case from a joint platform. 5 A drive A1, A2, A3 each has an M1 motor,
M2, M3 and of a driving pulley 1a, 1b, 1c. The motor M1, M2, M3 is in active contact with the driving pulley 1a, 1b, 1c and, by means of this driving pulley 1a, 1b, 1c, drives the traction member Z1, Z2, Z3. The drive pulley 1a, 1b, 1c is configured to be suitable for accommodating one or more traction members Z1, Z2, Z3. The traction members Z1, Z2, Z3 are preferably belts, such as for example trapezoidal belts with ribs on one of their sides that engage in one or more recesses on the side of the drive pulley. Strap variants can also be used, like the flat belts and the belts with unilateral or bilateral teeth, with the corresponding pulleys 1a, 1b, 1c. In addition, different types of cables can also be used, such as single, double or multiple cables. The traction members Z1, Z2, Z3 have steel, aramid or Vectran wire branches. The at least three elevator cars 7a, 7b, 7c and three counterweights 12a, 12b, 12c are suspended from the traction members Z1, Z2, Z3 in the manner of a hoist. The elevator cars 7a, 7b, 7c have at least a first and a second diverting pulley 2a, 2b, 2c, 3a, 3b, 3c, which are fixed to the lower part of the elevator cars 7a, 7b, 7c. These deflection pulleys 2a, 2b, 2c, 3a, 3b, 3c have on their circumference one or more grooves, which are made in such a way that they can accommodate one or more traction members Z1, Z2, Z3. Accordingly, the deflection pulleys 2a, 2b, 2c, 3a, 3b, 3c are suitable for guiding traction members Z1, Z2, Z3 and contacting the latter. An elevator car 7a, 7b, 7c is thus preferably suspended as a lower rig. In an optional embodiment, the deflection pulleys 2a,
2b, 2c, 3a, 3b, 3c are in the upper part of the elevator car 7a, 7b, 7c. According to the above explained, the elevator car 7a, 7b, 7c is suspended in such a case as a top rig. In the upper part of the counterweights 12a, 12b, 12c there is a third deflection pulley 4a, 4b, 4c, which is also suitable, similarly to the deflection pulleys 2a, 2b, 2c, 3a, 3b, 3c, for housing one or more traction members Z1, Z2, Z3. Accordingly, the counterweight 12a, 12b, 12c is preferably suspended from the third deflection pulley 4a, 4b, 4c as the upper gear, below the corresponding drive A1, A2, A3. The traction member Z1, Z2, Z3 is guided from a first fixed point 5a, 5b, 5c to a second fixed point 6a, 6b, 6c, from a first box wall to a second box wall, through the first , second and third deflection pulleys 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c and the drive pulley 1a, 1b, 1c. The first fixed point 5a, 5b, 5c is opposite the corresponding drive A1, A2, A3, approximately at the same box height, close to a first or a second box wall. The second fixed point 6a, 6b, 6c is located near the corresponding drive A1, A2, A3, in a second or a first opposite box wall. From the first fixed point 5a, 5b, 5c, the traction member Z1, Z2, Z3 extends downwards along a first or a second box wall to the second deflection pulley 3a, 3b, 3c, embraces this last from outside to inside at an angle of approx. 90 ° and continues until the first deflection pulley 2a, 2b, 2c. The traction member Z1, Z2, Z3 embraces this first deflection pulley 2 a, 2 b, 2 c from inside to outside, again at an angle of approx. 90 °, and then extends upwards along the elevator car 7a, 7b, 7c
to the driving pulley 1a, 1b, 1c and the latter embraces from the inside to the outside at an angle of approx. 150 °. The hugging angle can be adjusted within a range of 90 to 180 °, depending on how the optional adjusting pulley 13a, 13b, 13c is adjusted. Then, the traction member Z1, Z2, Z3 extends downwards along a second or a first box wall up to the third deflection pulley 4a, 4b, 4c, the latter engages the latter from outside to inside at an angle of approx. 180 ° and extends again upwards along a second or a first box wall to the second fixed point 6a, 6b, 6c. As mentioned above, an optional component of the drive A1, A2, A3 is an adjusting pulley 13a, 13b, 13c. This adjusting pulley 3a, 13b, 13c makes it possible to adjust the grip angle of the traction member Z1, Z2, Z3 in the drive pulley 1a, 1b, 1c, or increase or decrease it to transmit the desired traction forces of the drive pulley. 1a, 1b, 1c to the traction member A1, A2, A3. Depending on the distance of the adjusting pulley 13a, 13b, 13c to the drive pulley 1a, 1b, 1c, the distance of the tension member Z1, Z2, Z3 can also be adjusted to the drive A1, A2, A3, to the counterweight 12a, 12b , 12c or the elevator car 7a, 7b, 7c. In this way, a friction-free guide of the traction members Z1, Z2, Z3 is ensured in the housing between the drive pulley 1a, 1b, 1c and the first deflection pulley 2a, 2b, 2c. An elevator car 7a, 7b, 7c and the drives A1, A2, A3, the drive pulleys 1a, 1b, 1c, the diverting pulleys 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c, the optional adjusting pulleys 13a, 13b, 13c, the counterweights 12a, 12b, 12c, the traction members Z1, Z2, Z3 and the corresponding fixed points 5a, 5b, 5c, 6a, 6b, 6c in each case constitute a unit of elevator. Therefore, Figure 1 shows an elevator that has three elevator units, which
another part constitutes a triad 14. Starting from the central elevator unit with the elevator car 7a, the lower adjacent elevator unit with the elevator car 7b and the upper adjacent elevator unit with an elevator car 7c are each arranged as an inverted image with respect to the central one. Thus, the drives A1, A2, A3 of the elevator units are in opposite case walls, ie the first and the second case wall, and also the drive pulleys 1a, 1 b, 1c, the diverting pulleys 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c, the adjusting pulleys 13a, 13b, 13c, the counterweights 12a, 12b, 12c, the traction members Z1, Z2, Z3 and the fixed points 5a, 5b 5c, 6a, 6b, 6c of corresponding adjacent elevator cars 7a, 7b, 7c are arranged in the form of an inverted image. This rule of arrangement in the form of inverted images of central and adjacent elevator units is also applicable for any number of elevator units installed in a box. Another feature of the arrangement of the elevator units is that the drives A1, A2, A3 and the corresponding first fixed points 5a, 5b, 5c are placed at approximately the same height in opposite case walls, ie the first and the second one. second wall of box. The predetermined box height by the fixed points 5a, 5b, 5c and the drives A1, A2, A3 is at the same time the highest point that a corresponding elevator car 7a, 7b, 7c can achieve, since, in the form of embodiment shown, the traction member can not raise a suspension point of an elevator car 7a, 7b, 7c above the height of the drive pulley 1a, 1b, 1c. The drives A1, A2, A3 and the first fixed points 5a, 5b, 5c of the central elevator car and the adjacent ones 7a, 7b, 7c are generally placed at different
box heights. Thus, the elevator cars 7a, 7b, 7c can reach only different maximum case heights. Accordingly, the central elevator car and the adjacent elevator cars 7a, 7b, 7c are assigned different cabin areas in which said elevator cars 7a, 7b, 7c can be moved. In FIG. 1, the cab areas K1, 2, K3 assigned to the elevator cars 7a, 7b, 7c can be seen, and it can be seen from this that, in the configuration described above, the case height of a drive A1, A2 , A3 determines the maximum box height of one of these cabin areas K1, K2, K3. In contrast, the minimum box height of a cabin area K1, K2, K3 is defined by the drive A1, A2, A3 of the elevator unit located two positions below. In the example shown, the counterweight 12c of the upper adjacent elevator car 7c and the drive A2 of the lower adjacent elevator car 7b, located two positions below, are in the same first or second carcass wall due to the design a inverted image mode of the central and adjacent elevator units. Thus, the minimum box height that the counterweight 12c can reach is limited by the drive A2 which is located under the same box wall. The translation range of the counterweight 12c between the drive A2 and the drive A3, while the corresponding elevator car 7c and the counterweight 12c being suspended in a 2: 1 ratio, thus defines the cab area K3 of the cab of elevator 7c. If this system is applied to triad 14, cabin areas K1, K2, K3 partially overlapped, overlapping only central and adjacent cabinets K1, K2, K3. Thus, in a high-rise building with several triads arranged one above the other, all the floors that are in a central cabin area K1 receive service from two elevator cars.
According to FIG. 2, the elevator cars 7 a, 7 b, 7 c are guided by two car guide rails 10.1, 10.2. The two cabin guide rails 10.1, 10.2 form a junction plane V that extends approximately for each of the centers of gravity S of two elevator cars 7a, 7b, 7c. In the embodiment shown, the elevator cars 7a, 7b, 7c are suspended eccentrically. Here only the arrangement of two elevator units located one above the other is shown. However, for the Z3 at its center of gravity. Since the elevator cars 7a, 7b, 7c are eccentrically suspended, the counterweights 12a, 12b, 12c are offset laterally, close to the third and fourth box walls. The axes of rotation of the drive pulleys 1a, 1b, 1c and of the deflection pulleys 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c are parallel to the first or the second box wall. In the embodiment shown, the aforementioned components are configured so that they can accommodate, guide or, in the case of the drive pulley 1a, 1 b, 1c, also move four parallel traction members Z1, Z2, Z3. In order to accommodate the traction members Z1, Z2, Z3, the deflection pulleys 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 4c and the drive pulleys 1a, 1b, 1c have four contact surfaces configured in particular which, in the case of cables, are for example designed as grooves or, in the case of belts, are also designed, for example, as curved surfaces or as a toothing or, in the case of a flat shaped contact surface, are provided of guide flanges. These four contact surfaces can be applied either on a cylindrical body set or separately on four individual pulleys with a joint axis of rotation. Knowing this embodiment, the technician in the matter has
open many possibilities of variation depending on the task in question. For example, these one to four or more individual pulleys can be arranged on a turning axis with or without spacing between them. At the same time, depending on the design, each pulley can accommodate between one and four traction members Z1, Z2, Z3, and if necessary also more. During the normal operation of the elevator, the elevator cars 7a, 7b, 7c are placed in a plant stop flush with the floor and the car doors 8 are opened together with the box doors 9, to allow passengers to pass through from the floor to the elevator car 7a, 7b, 7c and vice versa. Figure 3 shows an alternative suspension arrangement with elevator cars 7a, 7b, 7c suspended centrally. Here only the arrangement of two elevator units located one above the other is shown. However, it is obvious to the person skilled in the art that the arrangement of other pairs of elevator units located one above the other is performed analogously. The traction members Z1, Z2, Z3 are guided by the deflection pulleys and the drive pulleys 1a, 1 b, 1c on both sides of the connection plane V. The suspension is advantageously arranged symmetrically in relation to the connection plane V Since in this case the center of gravity of the suspension essentially coincides with the center of gravity S of the elevator car 7a, 7b, 7c, no additional moment acts in the car guide rails 10.1, 10.2. In this centric suspension of the elevator cars 7a, 7b, 7c, the deflection pulleys 2a.1, 2a.2, 2b.1, 2b.2, 3a.1, 3a.2, 3b.1, 3b.2 and the corresponding pulleys 1a.1, 1a.2, 1 b.1, 1 b.2 consist of at least two pulleys, arranged to the left and right of the joint plane V. The pulleys of
deflection 4a, 4b, 4c of the counterweights 12a, 12b, 12c also consist of two pulleys, which are arranged to the left and right of the joint plane V but which in figure 3 have not been shown for greater clarity. In the present example, the deflection pulleys 2a.1, 2a.2, 3a.1, 3a.2 and the drive pulley 1a.1, 1a.2 corresponding to the central elevator car 7a are at a first distance X of the connecting plane V and the deflection pulleys 2b.1, 2b.2, 3b.1, 3b.2 and the drive pulley 1b.1 and 1b.2 corresponding to the lower adjacent elevator car 7b are at a second distance x of the junction plane V, the second distance x being smaller than the first distance X. Thus, with a centric suspension of the elevator cars 7a, 7b, 7c, a conflict-free guide of the control bodies is guaranteed. traction Z1, Z2, Z3. Also in this case it is advantageous if the counterweights 12a, 12b, 12c are suspended from the traction members Z1, Z2, Z3 at their center of gravity S, between the car guide rails 10.1, 10.2 and the first or second wall of box. Since the elevator cars 7a, 7b, 7c are now centrally suspended, the counterweights 12a, 12b, 12c are also located in a central area of the first and second box walls. Thanks to this central position of the counterweights 12a, 12b, 12c, the free space between the lateral ends of the counterweights 12a, 12b, 12c and the third and fourth box walls is greater. In this way, free space is obtained for the configuration of the counterweights 12a, 12b, 12c. Thus, for example, a thinner and wider counterweight 12a, 12b, 12c can be used to take better advantage of the space. With a given cross section of the box, the elevator car 7a, 7b, 7c gains in width, or with a given cabin size the cross section of the box can be reduced. The variants of centric and eccentric suspension shown in the
Figures 2 and 3 can be combined at will with the following examples of Figures 5 and 6. As shown in Figure 4, the drive A1 has an engine M1, preferably an electric motor, a drive pulley 1a and optionally a pulley of adjustment 13a, with which the angle of engagement of the traction member Z1 can be adjusted around the drive pulley 1a and the horizontal distance of the traction member Z1 to the drive A1, to the elevator car 7a or to the counterweight 12a. The motor M1 is located vertically on the drive pulley 1a. Thanks to this arrangement, the drive can be placed in the free projection of the counterweights 12a, between the elevator cars 7a and the first and second case walls. In this way, the elevator cars 7a can bypass the drives A1 and the drives A1 can be installed in a space of the box that would otherwise not be used. Compared with elevators without a conventional machine room, the space of the upper part of the box and / or the pit is gained thereby. According to FIG. 4, the drive A1 is fixed on a crosspiece 19, which is attached to the car guide rail 10.1 and / or to the counterweight guide rails 11a.1, 11a.2. In figure 4 can be seen further: the third deflection pulley 4a, from which the counterweight 12a is suspended, and in the bottom the elevator car 7a. The example shown here is inverted laterally with respect to the arrangement of FIG. 2 in relation to the connection plane V. There is also the option of fixing the drives A1 directly to the box walls, which may involve saving the crosspieces 19. Figure 5 shows an installation of elevators for a building
with division into zones. A building area G1, G2 is composed of several vertically overlapping floors of the building. At least one of these plants in a building area G1, G2 is a so-called transshipment plant U1, U2. From one area of building G1 to another area of building G2 you can reach, normally, by means of a passenger lift that only stops at the transshipment plants. The number of other floors assigned to an area of building G1, G2 is defined by those floors that are served by a passenger lift elevator 14.1, 14.2. This passenger withdrawal elevator 14.1, 14.2 performs the fine distribution of the passengers from the transshipment plants U1, U2 to the destination plants. The building is here divided into two building zones G1, G2. Each of these building areas G1, G2 is assigned a triad 14.1, 14.2, which exclusively serves plants of the assigned building area G1, G2. The installation of elevators has three elevators that are arranged in two boxes 15.1, 15.2. In the first box 15.1 there are two triads 14.1, 14.2 superimposed with six elevator units, six elevator cars and the cabin areas K1.1, K1.2, K2.1, K2.2, K3.1, K3.2 corresponding. Thus, a change from the first building area G1 to the second building area G2 is forced by the elevator of the second box 15.2 and only of the transfer floors U1.1, U1.2 of the building area G1 to the transshipment plants U2.1, U2.2 of the building area G2. The two triads 14.1, 14.2 deal with the transport of the passengers of the transshipment plants U2.1, U2.2 to a plant of the corresponding building area G1, G2 and between any two floors within a building zone G1, G2 In this way, a more efficient channelized transport of passengers within the building can be achieved.
The first box 15.1 can optionally be subdivided into two separate individual boxes with one lift each. The box height of these individual boxes depends largely on the height of the corresponding building area G1, G2. The advantage of such separate individual boxes is the absence of the chimney effect and thus also the absence of strong unwanted box winds, such as those that may occur in high-rise boxes. A high-performance elevator is moved by the second elevator car 15.2, serving exclusively the transshipment plants U1.2, U1.1, U2.1, U2.2. In the example shown, this high-performance elevator is a two-story elevator with two stationary cabins, which can be moved through the box 15.2 together and arranged vertically one above the other. These two-story cabins serve two transshipment plants U1.2, U1.1, U2.1, U2.2 arranged one above the other. Each cabin area K1.1, K1.2, K1.3, K2.1, K2.2, K2.3 and each building area G1, G2 has at least one transshipment plant U1.2, U1.1, U2.1, U2.2. In the upper building area G2, for example, the following arrangement results: the transfer floors U2.1, U2.2 of the two-story elevator are located in a central area of the building area G2, the lower transfer floor U2. 2 receives service from the lower cabin of the two-storey cab and the lower and adjacent lower elevator cabins of the triad 14.1 and the upper transfer facility U2.1 is similarly serviced by the upper cabin of the two-deck cab and of the central and adjacent upper elevator cars of the triad 14.2. Therefore, passengers whose floor of destination is in the central cabin area K1.2 always have two elevator cars of triad 14.2 to continue their journey.
While the adjacent cabin areas K2.2, K3.2 in each case preferably cover half of the floors of a building area, the central cabin area K1.2 preferably has two floors less than the number of floors assigned to the floor area. the area of building G2. The central elevator car can serve all the central floors of the building area G2, except the floors at both ends. Due to the vertical stacking of the elevator cars of a triad 14.2, the central elevator car can not exceed the upper and lower adjacent cabins, which at least keep a plant at one end of the building area G2 occupied at all times. . With a minimum size of the central cabin area K1.2, this covers the two transshipment plants U2.1, U2.2. In this case, the central elevator car of the triad 14.2 for the building area G2 fulfills the function of an escalator 16, transporting the passengers of the upper transshipment plant U2.1 to the lower transshipment plant U2.2 and vice versa. The two transshipment plants U2.1, U2.2 are then also the only plants in the G2 building area that receive service from two elevator cars of the triad 14.2. On the other hand, in the maximum extension of the central cabin area K1.2, the floors of the two ends of the building area G2 are the only floors that only receive service from the adjacent lower or upper elevator cabin of the triad 14.2 . With a maximum extension of the central cabin area K1.2, all other floors receive service from two elevator cars. The arrangement of the cab areas K1.1, K2.1, K3.1, of the corresponding elevator units and of the transshipment plants U1.1, U1.2 in the building area G1 essentially corresponds to the arrangement of the elements mentioned in the area of building G2. An important additional aspect concerns
to the transshipment plants U1.1, U1.2 of the lower building area G1. The two transfer floors U1.1, U1.2 of the lower building area G1 are connected by an escalator 16. Escalators are frequently used in building lobbies. The lobbies of buildings are floors through which the passengers access the building and leave it again and for this reason they are frequented by numerous passengers. YesFor example, the lower transshipment plant U1.2 is the lobby of a building, passengers arriving if necessary quickly to the upper transshipment plant U1.1, thanks to the large transport capacity of the escalator 16 , or, when leaving the building, they arrive quickly from said floor to the lobby of the building. Depending on the type and position of the building, the lobby of the building can be found on any floor of the building. As a general rule, the building lobby receives at least the high-performance elevator of the second box 15.2. Figure 6 shows a building with two additional building areas G3, G4 and triads 14.3, 14.4 corresponding to the car areas K1.3, 2.3, K3.3, K1.4, K2.4, K3.4, as well as the corresponding transshipment plants U3.1, U3.2, U4.1, U4.2. In this way, as many triads 14 as desired can be arranged one above the other. The invention is not limited to the embodiments shown. Knowing the invention, it will be easy for the person skilled in the art to optimize different parameters for specific building forms. Instead of a two-story cabin, you can also move through a second box 15.2 one or several individual cabins or multiple cabins, which have more than two cabins joined together. The number of floors assigned to a building area G can also be
choose freely. The building G areas also do not have to have the same number of floors, but it can vary from one building area to another. Nor do they always have to assign only triads 14 to a zone of building G. The zones of building G can also be assigned groups of four, five, six, etc. Cabin zones do not have to be symmetrically designed within a triad. Depending on the position of the drives and the transshipment plants U, these cabin areas K can be freely adapted to the particularities of the building. Finally, the transshipment floors U can also be arranged freely as regards their number and position in a building area G, depending on the cabin areas K or the number of cabins in a multiple cabin. The simple calculation below shows that thanks to the invention a considerable increase in transport capacity can be achieved. For a building area G2 with, for example, ten floors, according to the current state of the art, two elevator cars serve, in each case, nine floors, that is to say that each elevator car has a transport coefficient per floor. 1/9, weighted by the number of plants to be serviced, which is a measure of the transport capacity of the elevator car in a given plant. For the plants at both ends, which in each case receive service from only one elevator car, this results in a transport coefficient of, in each case, 1/9, and for a central area of eight floors, where both Overhead cabins overlap, a transport coefficient of 2/9. According to the invention, the adjacent cabin areas K2.2 and K3.2 serve, in each case, five upper floors and five lower floors and the central cabin area K1.2 to eight floors. As a result, for the area in which
they overlap the cabin areas, a transport coefficient of 1/5 plus 1/8 or 13/40 and, for the end plants, a transport coefficient of 1/5. This simple calculation example demonstrates that an obviously greater transport capacity is achieved for all the plants in the G2 building area. The increase in transport capacity for the plants at both ends is even overproportionally large. In addition, it is easy to realize that this increase in transport capacity is also applicable for a number of plants other than 10 in a building area.
