Definitions

  • the present invention relates to. an elevator system especially for high-rise multi-story buildings where a passen- ger wanting to reach one of the highest floors has to change over to an elevator that mainly serves only these highest floors.
  • the building is often divided vertically into zones, of which the lowest zone is a so-called low-rise zone extending from the entrance floor to a certain height, with some of the elevators in the building serving the traffic needs of the floors in this zone while the rest of the elevators in the building serve primarily or exclusively the floors above the low-rise zone.
  • the entrance floor may also be called ground floor, even in cases where the building has floors below the entrance floor and has elevator traffic to these floors.
  • the elevator traffic to the highest floors in very tall buildings is implemented by using one or more so-called sky lobbies, which are served by elevators running between sky lobbies and entrance floors, generally shuttle elevators that do not stop at any other floors, and local elevators serving the floors within their zone.
  • the zone containing the top- most floors in the building, and sometimes also the zone below it, is called a high-rise zone.
  • between these zones there may be one or more intermediate zones, i.e. so-called mid-rise zones, for serving the intermediate floors from their own sky lobbies.
  • lo- cal elevators serving different zones may form one or more elevator groups or they may belong to the same elevator group, and so may the shuttle elevators in the building.
  • the sky lobbies as well as the entrance lobby may comprise several floors, especially if the shuttle elevators have a car with two or more decks.
  • the entrance lobby and the sky lobbies are usually two- floor solutions in which the upper passenger compartment of a double-deck elevator car stops at the upper floor of a two-floor entrance lobby or sky lobby and the lower passenger compartment correspondingly at the lower floor of the entrance lobby or sky lobby.
  • a double-deck shuttle elevator can also be applied in solutions where some of the entrance and sky lobbies comprise two floors and some only one floor, e.g. in such manner that the entrance lobby comprises two floors and the sky lobby one floor, in which case a double-deck elevator car may have to park with both the upper and the lower passenger compartment separately at a one-floor elevator lobby.
  • a typical group is a group consisting of eight elevators and serving a single zone, which may consist of e.g. floors 1-15. Often such an elevator group is needed for each zone, for example for the mid-rise zone for floors 16-30 and the high-rise zone for floors 31-45.
  • elevator shafts are used as load- bearing structures, which often or at least to a very large degree support and stiffen not only the elevator shafts themselves but also all the rest of the building.
  • the elevator shafts usually form a continuous structure extending from the basement of the building up to the highest floors in the building. This takes up a fairly large space in the building and it is not necessarily even fully utilized by the elevator system of the building or otherwise.
  • the elevators serving the mid-rise and high- rise zones do not stop at lower floors, so the lobby space and especially the shaft space required by them constitute waste space expensive to the owner of the building. Unused lobby space can be utilized e.g. as storage or lavatory space on different floors, but corresponding shaft space can generally not be utilized in any way.
  • each car can serve all floors, but only car may be moving at a time.
  • the cars can move simultaneously in different zones but only in the same direction at a time.
  • the cars can travel simultaneously in different directions, provided that safety is guaranteed. For example, when the two cars below the topmost one are going downwards, the topmost car can go upwards.
  • the elevator system proposed is -very complicated and it is obvious that in such a system there is the problem of how to construct a control system that is sufficiently simple and safe. Even if the control system is ever so safe in principle, there may occur a failure in the system, in which case a collision between two cars is possible.
  • United States patent no. US 6,273,217 also discloses an elevator solution in which more- than one elevator car moves in the same elevator shaft.
  • the solution proposed in this patent is focused on preventing a possible collision between two elevators on the basis of a program. If a risk of collision appears, one of the elevator cars is moved to give way to the other one. In this case, too, the problem is expressly a risk of collision, because if the program fails or a program error occurs, it is always possible that two elevators traveling towards each other in the same shaft collide.
  • the object of the present invention is to overcome the above-mentioned drawbacks and achieve an economical, reliable, safe and well working elevator system for high-rise buildings, in which elevator system one or more elevator cars move in the same shaft independently of the each other. Another object is to arrange the use of elevators so as to achieve a good transport capacity and efficient utilization of building space. A significant aim is to ap- ply an elevator solution without machine room known in itself to create a more efficient elevator system for high- rise buildings. These objects and aims of the invention may be distinct from each other or appear as combinations in respect of the inventive solutions described below and the advantages achieved by these solutions.
  • the invention concerns passenger guidance and synchronization of the control of elevator groups in an arrangement where elevator groups without machine room are installed one above the other in the same shaft with a shuttle elevator group feeding traffic from sky lobbies to local elevator groups without machine room.
  • the shuttle elevators must be filled uniformly at the entrance floor so as to minimize the number of times the shuttle elevators stop. In this way, a high transport capacity of the shuttle elevators is maintained and the number of shuttle elevators required is small.
  • the shuttle elevator .group consists of double- deck elevators, the upper and lower cars should be loaded evenly at the main entrance floor.
  • the guidance provided in the main lobby should be simple and coherent so that people will learn to find the right elevator and/or the right passenger compartment of an elevator car.
  • the solution of the invention has the advantage of allowing simple solutions to be used to achieve a reliable and safe elevator system that guarantees a good transport capacity in high-rise buildings and makes it possible to save expensive floor area.
  • the space saving is easily 20 percent or even over a third of the space otherwise needed by the elevator system of the building.
  • the elevator shaft space required for the elevator system of a skyscraper is two thirds of the space needed in solutions conventionally used, but nevertheless at least the same capacity is achieved as in prior-art solutions. Space savings are achieved both on the lower floors, where the saved space is particularly valuable, and . in higher parts of the building.
  • the elevator cars of local groups move independently of each other in the same shaft and they never collide be- cause the hoisting ropes of different elevator cars do not overlap with each other in the vertical direction and it is therefore impossible for the elevator cars to enter into each other's traveling range.
  • An advantageous solution is one in which the local elevators departing in upward and downward directions from sky lobbies are separated in the sky lobbies in specific lobby areas, and in which these lobby areas are served by different shuttle elevators or different passenger compartments of shuttle elevators, for example in such manner that the base floor of an up-going local elevator group is the floor served by the upper passenger compartment of a double-decker elevator car and the base floor of a down- going local elevator group is the floor served by the lower passenger compartment of a double-decker elevator car.
  • the guidance in the entrance lobby to the shuttle elevators or shuttle elevator passenger compartments feeding the local groups is clear and easily perceivable.
  • the loading of the shuttle and local elevators is balanced, if necessary by using a destination call solution, allowing optimal transportation system ratings relative to the transport capacity to be achieved.
  • a destination call solution allowing optimal transportation system ratings relative to the transport capacity to be achieved.
  • the transport capacities, intervals of shuttle elevator groups should fulfill general requirements and in multi- deck solutions the loading of the cars should be uniform, and clear passenger guidance must be provided both on the main entrance floor and on the sky lobbies.
  • Inter-floor traffic should be synchronized so that a connection exists from each local group to the other local groups either via a local group or a shuttle elevator group. If the shuttle elevator has a multi-deck car, the traffic between the floors in sky lobbies can be taken care of by loading sev- eral decks simultaneously to serve different floor areas. Simultaneous loading of the passenger compartments of the elevator car increases the transport capacity and decreases the area required by the shuttle elevators.
  • one solution for handling the internal traffic is to add extra local groups serving the sky lobbies.
  • the number of floors served by the mini- groups should be at least equal to the number of decks in the shuttle elevators.
  • the floor heights in the building may be equal if the floors served by the local elevator groups are interlaced in a staggered manner.

  • Fig. 1 represents the above- mentioned prior-art elevator system for high-rise buildings. Let us consider for example a 45-floor building with fifteen floors in each zone. The number of floors in each zone is determined by the car size and speed of the elevators used. The system comprises three different vertical zones, so it is necessary to have three different sets 1, 2, 3 of elevator shafts, of which shaft set 1 forms the lowest zone, where e.g. a group of eight elevators serves all fifteen floors from the ground floor 9 to the topmost floor 10 of the zone. Fig. 1 shows the elevator doors of four elevators only on the ground floor 9 and on the topmost floor 10 of the zone. Within this zone, the elevators can stop at all floors.
  • the second zone in the prior-art elevator system is a so- called mid-rise zone, which may also comprise a group of eight elevators installed in a separate set 2 of shafts.
  • This group only serves the ground floor 9, the first sky lobby 8 , which in the solution according to the example is located on the fifteenth floor of the building, and all floors upwards from this floor up to a second sky lobby 8a, which in the solution presented in the example is lo- cated on the thirtieth floor of the building.
  • the elevators in shaft set 2 never stop within the zone 5 of the fifteen lowest floors except at the ground floor. If these elevators do not have a so-called express function, they do not admit passengers into the elevators in shaft set 2 from the ground floor 9 at all but only travel within the area 4 of shaft set 2.
  • Fig. 1 shows only the lowest floor 9, 10b and lib and the topmost floor 10, 11 and 12 of each zone. The drawbacks of this system were described above.
  • Figures 2-6 illustrate an elevator system applying the invention.
  • the separate set 1 of elevator shafts for the low-rise zone presented in Fig. 1 as well as all the elevator lobbies of these floors have been left out altogether.
  • the system comprises only two sets of elevator shafts.
  • the first shaft set 13 comprises eight elevator shafts, each of which accommodates an elevator provided with a so- called double-deck elevator car 21 and having a speed at least as fast as or faster than the elevators traveling elevator shaft set 14.
  • the ground floor 9 is provided with an escalator arrangement 20 that passengers can use to ascend to and descend from a second ground floor level 9a.
  • the first elevator shaft set 13 extends from the ground floor to a height of about 2/3 of the total height of the building, in other words, in a 45-floor building the second sky lobby 8a in the upper part of the first shaft set comprises floors 30 and 31 of the building and correspondingly the first sky lobby placed midway between the ends of the first shaft set comprises floors 15 and 16 of the building.
  • the second elevator shaft set 14 extends as a substantially continuous structure from the ground floor 9 of the building to the height of the whole building, i.e. to the topmost floor 45, which is represented by elevator lobby 12.
  • the second elevator shaft set 14 consists of three substantially identical zones placed one above the other.
  • the shafts in these zones are hereinafter referred to as local shafts 17, 18 and 19.
  • Each local shaft is substantially identical in cross-section and each local shaft accommodates one elevator car 22 serving all floors comprised in the local shaft.
  • each elevator shaft in shaft set 14 accora- modates three elevators one above the other, each one in a separate local shaft.
  • ⁇ elevator' means at least the elevator car 22 together with the machine 23 and elevator ropes 24.
  • the elevators in the local shafts are slower or at most as fast as the so-called shuttle elevators in shaft set 13.
  • the first and second elevator shaft sets are connected to each other via the two two-floor sky lobbies.
  • the first sky lobby 8 is at a height of about one third of the total building height, in other words, in the example it comprises floors fifteen and sixteen with elevator lobbies 10 and 10a.
  • the second sky lobby 8a is located at a height of about two thirds of the total height of the building and comprises in the example floors thirty and thirty-one with elevator lobbies 11 and 11a.
  • Each sky lobby is provided with an escalator arrangement 20 to allow passengers to move from the lower floor of the sky lobby to the upper floor or vice versa.
  • first and second sky lobbies 8 and 8a each comprise an upper and a lower transfer floor in such manner that each lower transfer floor, which also include eleva- tor lobbies 10 and 11, is the topmost floor level for the elevator car 22 coming to it from below and departing downwards from it in local shafts 17 and 18.
  • each upper transfer floor which also include elevator lobbies 10a and 11a, is the lowest floor level for the elevator car 22 coming to it from above and departing downwards from it in local shafts 18 and 19.
  • each shaft is continuous, extending from the ground floor 9 to the topmost floor of the building if necessary, where elevator lobby 12 is located.
  • each shaft there are more than one local shaft 17, 18 and 19 one above the other, and each local shaft accommodates one elevator with an elevator car 22 serving the floors comprised in the local shaft in question.
  • the system described in the example comprises three local shafts 17, 18 and 19 placed one above the other, each of which accommodates one elevator car. All the elevator cars in the same shaft are substantially identical and are disposed in substantially the same vertical plane one above the other.
  • Fig. 5 is a more detailed illustration showing how the elevator cars 22 are disposed independently of each other one above the other in the same shaft.
  • the elevator car 22 in the middle local shaft 18 stands at its lowest position in elevator lobby 10a on the upper floor of sky lobby 8.
  • Below the elevator car is a framework of supporting beams 25 serving as the shaft bottom of the local shaft 18 and additionally provided with a strong steel wire net to stop any falling objects in this part of the shaft.
  • the vertical distance between the supporting beam framework and the lowest position of the elevator car 22 has been fitted to be such that the prescribed dimensions of the space below the elevator car are obtained.
  • fixed buffers for stopping the elevator car 22 on a buffer are mounted on the supporting beam framework 25 or on the wall of the lower part of the local shaft. The buffers are not shown in the figures.
  • the elevator machine 23 driving the lower elevator car, and the elevator ropes 24 passing around the traction sheave of the machine are fastened to the elevator car 22 in a suitable manner.
  • the lower elevator car 22 is shown in a local shaft 17, in its upper position at sky lobby 8, so it is standing at elevator lobby 10 on the lower floor of the sky lobby.
  • the elevator machines 23 of all the elevators in the same shaft are mounted in a corresponding way in the upper part of each local shaft 17 placed one above the other.
  • there are also three elevator machines 23 in each shaft and no machine rooms are needed for the elevators in the local shaft 17.
  • Each local shaft is additionally provided with a counterweight, which is shown partly in shaft 17. When the elevator car 22 is in the upper part of the shaft, the counterweight is in the ⁇ lower part and vice versa.
  • the elevator machine 23 is of a- gearless type and substantially flat, so it can be secured e.g. to an elevator guide rail or to a shaft wall in the space between the elevator car 22 and the shaft wall. In this way, the elevator cars 22 can easily be made independent of each other, because the elevator ropes of different elevators do not overlap with each other in the vertical direction in any part of the shaft.
  • Fig. 6 presents correspondingly a simplified view the elevator car 21 moving in the elevator shafts of the first shaft set 13.
  • an elevator machine is pro- vided at the upper end of each shaft, and the elevator car 21 is suspended on the ropes 27 of the machine.
  • the upper and lower cars of the elevator car 21 are fastened together by means of fastening elements 26 in such manner that, when the upper car is at the upper floor of the first sky lobby 8, the lower car is correspondingly at the lower floor of the same sky lobby.
  • the elevator is at the second sky lobby 8a or at the ground floor 9.
  • the ground floor and the sky lobbies are provided with clear guiding signs for passengers, showing from which level each floor can be reached. Now if we suppose that a passenger is going to floor 20, he will see on the ground floor a guide indicating that the floor in question can be reached by using elevators departing from the ground floor 9. The passenger therefore enters the lower car of the double-deck elevator car 21 at the ground floor 9 and as- cends on the elevator of shaft set 13 to the second sky lobby 8a, where he leaves the elevator in lobby 11 and walks in the sky lobby to an elevator car 22 of shaft set 14, which takes him downwards from floor thirty to floor twenty.
  • Figures 7A, 7B, 7C, 7D, 7E, 7F, 7G are diagrammatic representations of alternative embodiments of the invention in the case of a 48-floor building.
  • the upwards or downwards pointing arrows in the figures indicate the direction of departure of local group elevator cars from a sky lobby or main lobby floor.
  • Elevators without machine room are installed one above the other as local elevators in the local shafts and the shuttle elevators are installed in shuttle elevator shafts.
  • the local elevator shafts are either continuous shafts extending from bottom to top and accommodating several elevators or they are shafts placed one above the other and containing a single elevator.
  • the shuttle elevators which are express elevators, are provided with multi-deck elevator cars in which the elevator car comprises two, three or even more passenger compartments one above the other.
  • a double-deck elevator car is relatively flexible in use and it already pro- vides a considerably improved shuttle elevator transport capacity as compared to a single-deck elevator car.
  • safety distances need to be provided above and below the paths of the elevator cars at the transfer floors, which can be achieved by making the sky lobby floors higher than the other floors in the building, for example by using an inter-floor distance of six meters instead of four meters or by leaving one floor between local elevators. If one floor is left between local elevators, then it may be necessary to provide in the sky lobby area a low-rise elevator to take care of traffic between the sky lobby floors, but on the other hand such a solution favors the use of a three-deck elevator car.
  • the load of the elevator cars can be equalized in many ways.
  • passengers are guided on the ground floor to the cars of multi-deck elevators in such manner that the elevators are assigned to zones such that they will only stop at every second sky lobby, from where the elevators depart upwards from the upper sky lobby and downwards from the lower sky lobby.
  • the guiding sign is shown in the figure in the area of the entrance lobby and the sky lobbies.
  • the shuttle elevator groups are presented as a wider area and the local groups as a narrower area, but the width or narrowness in itself has nothing to do with the width of the corresponding elevators.
  • the guiding information for pas- sengers is visibly shown in the figure and it can be displayed in the entrance and sky lobbies via fixed and/or variable displays and inside the elevator car via variable displays.
  • the solution presented in Fig. 7B very much resembles the solution presented in Fig. 7A, but in this case one shuttle elevator group has been divided so that some of the elevators serve upper sky lobby areas while some of them serve lower sky lobby areas.
  • Such a division can advantageously be designed to be permanent in respect of use of the building, in which case it is possible to make the elevator shafts of the elevators feeding the lower sky lobby areas lower than the elevator shafts of the elevators feeding the upper sky lobby areas.
  • FIG. 7A and 7B can be optimized for incoming traffic coming from the main lobby and the guidance directing passengers to local groups is clear.
  • the shuttle elevator group has been divided in half, one half serving the lower sky lobbies while the other half serves the upper sky lobbies.
  • Fig. 7C presents a solution where passengers are guided on the entrance floor to the cars of multi-deck elevators in such manner that the elevators always depart upwards from a sky lobby.
  • the shuttle elevators stop at each sky lobby, but they only unload one car at a time.
  • Guidance is so implemented that passengers are guided to that passenger compartment of an elevator car that feeds the corresponding local group.
  • the shuttle elevator group has to be somewhat larger than in the cases illustrated in Fig. 7A and 7B.
  • Fig. 7D presents a solution where the up-peak transport capacity has been increased in relation to the solution of Fig. 7C by dividing the shuttle elevator group in two parts.
  • the group can be correspondingly divided into several zones, especially if the system comprises a large number of elevators.
  • a shuttle elevator can stop at all sky lobby floors, allowing local groups to be loaded from both upper and lower floors.
  • destination control In such an elevator system it is very convenient to use destination control to equalize the load, in other words, different elevator cars are filled by utilizing information regarding the passengers' destination floors, obtained from the passengers either via a call device or in other ways before they enter an elevator car.
  • destination control people can be guided to shuttle elevators in such manner that each elevator will stop as few times as possible. Because in this case the control is based on knowing the elevator passengers' destinations before they enter an elevator car, the passengers can be effectively guided to different elevator cars according to the opti i- zation criterion currently valid in each situation. Therefore, rough floor division displays are not necessarily needed on the main entrance floor.
  • a destination floor call station placed in the entrance lobby provides guidance indi- eating the elevator car and the place. Passengers are loaded on local elevators by transporting them to a sky lobby where a shuttle elevator traveling in the appropriate direction is already stopping.
  • destination floor calls are used, if such a call is issued across an elevator group, the person will be taken to a sky lobby to which is coming a shuttle elevator which is traveling in the appropriate direction and which may already have been assigned a stop at the sky lobby for the destination floor. In this way, the number of stops is reduced and the performance and capacity of the system increased.
  • passengers departing from the main lobby can always travel upwards first on a shuttle elevator and then on a local elevator.
  • Figures 7E and 7F present solutions where the floor height of the sky lobbies in the building is small, i.e. generally the same height as the adjacent floors.
  • the elevators can be interlaced within the elevator group in a staggered manner such that one floor is left between the elevator of the lower local group and the elevator of the upper local group, in which case it is not necessary to have a larger distance between floors .
  • the upwards and downwards going local groups are adapted to the passage of the shuttle elevators.
  • the shuttle elevators are fixedly assigned to different zones to feed corresponding upwards and downwards going local groups. Inside the shuttle elevator, a car display shows the floors to be served.
  • Fig. 7E For extension floors, a special call button is needed, or in the case of destination control the service works without special call buttons.
  • Fig. 7F presents a solution where every second sky lobby has larger floor-to floor distances.
  • Fig. 7G presents a typical traffic arrangement in the elevator system of a building for inter-floor traffic occurring as a prevailing traffic type at other times than in- coming and outgoing peak traffic hours .
  • the elevator machines may be placed only partly in the elevator shafts, e.g. in such manner that substantially only the traction sheave is in the elevator shaft while the rest of the elevator machine is in a suitable shaft recess or equivalent.
  • An es- sential point is that a separate machine is provided for each elevator in the shaft, the machine being placed near the upper or lower end of the shaft in which the elevator car in question moves.
  • the number of zones disposed one above the other is not necessarily three but varies according to building height, volume of transportation required and selected elevator properties. These properties include the speed and size of the elevator car. It is preferable to choose the heights of the shafts needed in such a way that a double-deck elevator car 21 coming to the topmost sky lobby can unload passengers for both upward and downward connections .
  • the ratio of sky lobbies to local shafts may vary.
  • the number of sky lobbies may be more than two as in the example.
  • the height of the shafts may vary according to the shape of the building and the space in it or due to other reasons, e.g. the speed of the local elevators.
