Definitions

  • Elevator system having multiple elevator cabins
  • the invention refers to an elevator system according to claim one and a method according to claim nine.
  • said cabins can travel at different times, at different speeds, and in different directions, e.g., a horizontal transfer of a cabin or pair of cabins from an up shaft into a down shaft.
  • a cabin transferring between these shafts can travel at a different speed to a cabin which is ascending or descending. Whilst these cabins are travelling throughout the shaft, a collection of new passengers is gathering at various serviced floors throughout the building waiting for the return of the cabins so they can begin their elevator journey. This increases a passengers journey time and decreases handling capacity of the elevator system.
  • EP 2994406 B1 describes a system comprising a first hoistway having a shuttle section and serviced floors, a second hoistway having a shuttle section and serviced floors, a first elevator car, a second elevator car and a coupler physically connecting the first and second elevator cars, a transfer section for transferring at least one of the first elevator car and the second elevator car from one hoistway to another hoistway, wherein the elevator cars are decoupled for servicing the serviced floors.
  • This system however fails to address the problem of lengthy waiting times for passengers.
  • the invention refers to an elevator system comprising:
  • an elevator shaft comprising an up shaft and a down shaft
  • a first pair of elevator cabins comprising an upper cabin and a lower cabin
  • the up shaft comprises a vertically extending rail along which the respective pair of elevator cabins are movable; and- the down shaft comprises a vertically extending rail along which the respective pair of elevator cabins are movable;
  • the elevator shaft comprises a plurality of exchangers for transferring the pair of elevator cabins from the up shaft to the corresponding down shaft or vice versa via a horizontal movement along a horizontal rail.
  • Each pair of elevator cabins is adapted to travel to a plurality of floors, said floors preferably comprising
  • non-serviced floor can be located above the uppermost serviced floor.
  • non serviced floor can also be located below the lowermost service floor. When there is more than one non-serviced floor, they can be located at any particular location throughout a building.
  • the elevator system comprises
  • the elevator system comprises at least two further exchangers located at a serviced floor.
  • the elevator system comprises:
  • the serviced floors preferably comprise a plurality of entrance floors and sky lobbies.
  • the exchangers are only located at the entrance floors and not at any of the sky lobbies.
  • the elevator shaft has a height (H) that is represented by the formula (A) and/or (B): A) H 3 w(S) +x(NS)
  • - x is an integer which can be egual or non-egual to w;
  • each cabin there is one exchanger per cabin. This advantageously allows for each cabin to be transferred between shafts, optionally simultaneously, thereby decreasing waiting times and increasing handling capacity.
  • the upper cabin and the lower cabin of each elevator cabin pair are transferred between the up shaft and the down shaft simultaneously.
  • This advantageously provides a flow of pairs of elevator cabins throughout the elevator system such that there is preferably at least one pair of elevator cabins servicing at least the entrance level and/or a sky lobby at any one time, thereby improving handling capacity.
  • the invention also relates to a method for operating an elevator system comprising an up shaft and a down shaft,
  • a first pair of elevator cabins comprising an upper cabin and a lower cabin
