Definitions

• the present invention refers in general to elevators or service lifts for the transportation of persons or of loads, respectively, in high buildings and in industrial plants and, in particular, to an elevator system adequate for high buildings that allows the simultaneous access of persons or of loads to a multi-modular cabin, that reaches more than one floor at each of the stops of the mentioned elevator or lift.
• the capacity of transportation of an installation existing in a building may be duplicated and even quadruplicated.
• the increase of capacity is of 1 and 8 times the conventional or nominal capacity, respectively.
• the useres must go up or not, by the stairs of the building to the second or third floor of the building, from where they may enter into the upper cabins of the multi-cabin type elevators. This will depend on the version of this invention that is implemented. Thanks to this modular system the capacity of transportation of persons from for example the first and/or second floor up to the upper floors of the building, is increased considerably. The same is valid for the transportation of loads.
• the system may be extended eventually to a higher number of modules or cabins, depending on the number of floors of the building and on the demand of transportation of persons at determined hours of the day.
• the present invention refers to a multi-modular elevator system for a high building comprising at least two cabin modules, means for elevating the cabin modules and means for descending the cabin modules.
• the system basically comprises a lower cabin module and at least a first upper cabin module, the cabin modules being, contrary to the well-know "Pater.Noster" elevators, rigid bodies which are not collapsible.
• the cabin modules are piled up to form a column or tower, such that access to the lower cabin module is provided at a lower floor of the building and access to the first upper cabin module being provided on a higher floor of the building.
• a second and even more subsequent upper cabin modules may be provided.
• the system is designed such that access to one of the cabin modules is provided on odd-numbered floors whilst access to at least another cabin module is provided at even-numbered floors.
• the system comprises accessing means for selectively providing simultaneous access to the lower module and to the first upper module.
• the accessing means may comprise at least first doors for the lower cabin module and second doors for the upper module, whereby said first and second doors can be operated to open and close simultaneously or independently from each other.
• the first doors are orientated in a different direction than said second doors, so that users may access different wings of a building by selecting the cabin module which has the door being orientated to the wing they want to access.
• the cabin modules are comprised by a cabin body, as for example a housing or a framework, which comprises conventional aggregate and service elements like breaks, traction means, electrical connections etc.
• cabin body is designed to fit with an already existing conventional elevator shaft to thereby replace a conventional cabin.
• all modules have an identical transporting capacity and/or dimensions.
• the vertical extension of the elevator shaft By increasing the vertical extension of the elevator shaft, access may be provided to at least one cabin module at any floor.
• the vertical extension of the elevator shaft can be increased, by increasing the depth of the elevator pit, or by increasing the height of the top engine room.
• the capacity of transportation of persons or the volume of loads may be duplicated and even quadruplicated, in a building of multiple floors that counts with an elevator and where the possibility of installing other elevators parallel to the existing one or ones does not exist, wherein the capacity of the system particularly during the hours of maximum demand in respect of the persons or the loads to be transported, collapses.
• the proposed elevation system presents enormous advantages when being projected in a new design of building, due to the advantage of the volumetric distribution that is allowed in a new building. Therefore the area of distribution in the elevators hall is reduced, there being only two doors instead of eight.
• the invention relates to a multi-cabin type elevator system for existing, new high buildings or high buildings that are being projected, which allows the simultaneous access of users or loads into the mentioned multi-modular cabin, that reaches more than one floor at each stop of the elevator.
• This is achieved by using in an elevator having, for example, two superimposed cabin modules , the height of the access doors of which occupy the extension of two or more floors of the building.
• a higher number of modules as far as this is practical and it is justified by the height of the building may be considered.
• the stops amid the total trip will be equivalent to half of those in the case of a conventional elevator with only one cabin, which allows it to again duplicate the transporting, capacity by the reduction to half of the time journeyed.
• the merit of the system and of the corresponding multi-cabin type elevator proposed is that they allow utilizing available infrastructures, including the original cabin, requiring only to replace the existing motor by another adequate to displace the double of the load, as well as the cables, the balancing counterweight of the elevator system, in addition to the new cabin module that is superimposed to the original cabin.
• the scheme set forth in the preceding Table may also be prepared in an analogous manner for a cabin of three modules, in which case the increase in transportation capacity is even higher.
• the convenience of a system of three modules will depend on the number of floors of the building and the demand of use of such and its convenience must be evaluated for each case, considering technical and practical aspects relative to the use of the elevator system.
• Column I corresponds to the performance of a conventional elevator, provided with only one cabin of only one floor or of a mono-modular type. Such elevator starts its trip and then stops at all of the floors, a total of 19 times requiring a total of 342 seconds and having transported a maximum of 8 persons among the mentioned floors.
• the other columns represent the new proposal of the invention which, when optimized, achieves more than to quadruplicate the transportation capacity.
• the investment required is minimal when compared with that of the installation of more parallel elevators, without considering the definitive loss of m 2 occupied in the new installation of elevators and their corresponding cost-effectiveness.
• Column IV differs from the preceding column in that the height of the engine-room has been increased such that cabin "A" by an additional stop, may reach the last floor.
• Column V corresponds to an option in which besides increasing the height of the engine-room, the elevator pit has been deepened such that cabin "B" also reaches the first floor.
