Definitions

  • This invention relates to an elevator system and to a method for operating an elevator system, and more particularly to a multipurpose elevator system.
  • a challenge with traditional elevators is that the provided elevator car is usually optimized for transporting persons.
  • the provided elevator car is usually optimized for transporting persons.
  • Figure 1 illustrates a simplified side view of an elevator system 1 with an elevator car 2 which is arranged to move vertically in a hoistway 3 between landings 4 of a building 16.
  • the elevator car is moved by a hoisting machinery 5 which is controlled by an elevator control 6.
  • the hoisting machinery 5 utilizes a rope 18 to move the elevator car 2 and a counterweight 19 in the hoistway 3.
  • Figures 1 and 2 One alternative is to utilize a similar solution as illustrated in Figure 5 .
  • An advantage with the rolling surface 10 provided by the rolls 7 is that when loading or unloading cargo into the elevator car 2, the cargo can slide along the rolling surface due to the rotation of the rolls 7. This significantly simplifies loading and unloading of heavy cargo.
  • the elevator car 2 is provided with a floor section comprising one or more floor elements 11, which are movable between a load bearing position, where the one or more floor elements are aligned on top of the rolling floor surface 10 and provide a fixed floor surface, and a transport position, where the rolling floor surface 10 is revealed.
  • Figure 1 illustrates the one or more floor elements 11 in the transport position, where the elevator car is optimized for transport of cargo
  • Figure 2 illustrates the one or more floor elements 11 in the load bearing position, where the one or more floor elements 11 are aligned on top of the rolling floor surface 10 and provide a fixed floor surface for carrying the weight of person standing on it.
  • the elevator car 2 is provided with two floor elements 11, which are movable between the load bearing position and the transport position by rotation around pivot points 12.
  • each of the floor elements 11 is separately attached by pivot points to the elevator car, preferably proximate to the opposite side walls of the elevator car.
  • Proximity to the side walls 17 is advantageous, as in that case the area of the rolling surface 10 becomes as large as possible in the transport position.
  • the pivot points 12 make it possible to lift each floor element 11 from the horizontal load bearing position illustrated in Figure 2 to an upright vertical transport position illustrated in Figure 1 .
  • each floor element is located along a side wall 17 of the elevator car in an upright position, due to which the rolling surface 10 is revealed between the two floor elements.
  • the elevator car may be provided with a drive unit 13 (or drive units) such as an electric motor, a hydraulic motor or hydraulic cylinder, or a pneumatic motor or pneumatic cylinder which can be used to move the one or more floor elements 11 between the load bearing position and the transport position.
  • a control panel of the elevator car for instance, may be used to control the movement of the one or more floor elements 11 by utilizing electric power, hydraulic power or pneumatic power.
  • Still another alternative for moving the one or more floor elements 11 into the transport position is to completely remove the elements from the elevator car 2 to an elevator landing 4.
  • the elevator car may be provided with attachment points for attaching the one or more floor elements in position with screws (if needed), for instance, when the one or more floor elements 11 are in the load bearing position.
  • the elevator car 2 is provided with a sensor 14 providing the elevator control 6 with an indication about the position of the one or more floor elements 11.
  • the elevator control obtains information when the one or more floor elements 11 are in the transport position and when they are in the load bearing position. This information is useful, because it may be advantageous to stop the elevator car at different heights in the hoistway 3 in relation to the landings 4 depending on the position of the one or more floor elements 11.
  • the elevator control 6 is configured to stop the elevator car 2 at a higher position in relation to the landing 4 when the one or more floor elements 11 are in the transport position, than when the one or more floor elements 11 are in the load bearing position.
  • a construction time modification of the elevator car illustrated in Figures 1 and 2 may be utilized only during the construction time of the building. Consequently, for the construction time of the building the elevator car 2 may be set in a hybrid mode, where the rolling floor surface 10 and the one or more floor elements 11 have been provided to the floor 20 of the elevator car. Atthat stage, the elevator car is well suited for both transport of cargo and passengers, depending on if the one or more floor elements 11 are in the passenger load bearing position illustrated in Figure 1 or in the transport position illustrated in Figure 2 . However, once the construction time modification is no longer needed as the building is completed, this hybrid mode may no longer be needed.
  • the elevator car may be set in a person transport mode, by removing the rolls providing the rolling floor surface 10 and the floor elements 11. Consequently, the floor 20 of the elevator car may be revealed and possibly provided with a new coating for more permanent transport of passengers.
  • the elevator control 6 may, if necessary, be set into a new mode ensuring that the upper surface of the floor 20 is at the same level as the upper surface of the landings 4 in the hoistway, when the elevator car 2 stops at a landing.
  • Figures 3 to 5 illustrate a second embodiment of an elevator car 2'.
  • the second embodiment is very similar as the one explained in connection with Figures 1 to 2 . Therefore, in the following, the embodiment of Figures 3 to 5 will mainly be explained by pointing out the differences.
  • the elevator car is set into a hybrid mode, for the construction time of the building, for instance, due to which it is provided with rolls 7 providing a rolling surface 10 and one or more floor elements 11, which can be moved between the cargo transport position (illustrated in Figure 3 ) and the passenger load bearing position, as has been illustrated and explained in connection with Figures 1 and 2 .
  • the elevator car has additionally been provided with a height adjustable roof construction to obtain an increased interior height well suited for loading of long or high objects 15' into an elevator car 2'.
  • objects 15' which are higher than the height of the door opening 9' in the elevator car 2' can easily be loaded onto the rolling floor surface by tilting at the door, and subsequently turning into an upright position. After this the objects 15' can slide deeper into the elevator car 2' on the rolling surface.
  • a first alternative is to provide one single roof element 21' which can be attached in at least two alternative height positions to the elevator car 2'. This has been illustrated in Figure 3 by way of example.
  • the roof element 21' has attachment holes 22' at two different vertical heights, so that bolts 23' can protrude through the holes 22' on the selected height and attach the roof element 21' at a desired height position to the walls of the elevator car 2'.
  • Bolts and holes are naturally only one example of devices suitable for providing height adjustment for a single roof element 21'.
  • FIG. 3 Another alternative to provide a height adjustable roof construction is to utilize two different roof elements.
  • first roof element 21' illustrated in Figure 3 which provides an increased interior height for the elevator car 2' is replaced by a second roof element 21" as illustrated in Figure 4 , when the increased interior height is no longer necessary.
  • attachment of the second roof element 21" may be implemented with bolts 23', for instance.
  • Figure 5 illustrates in more detail an example of how the hoisting carried out with the hoisting machinery 5 and the rope 18 can be implemented. This solution can be utilized both for the embodiment of Figures 1 to 2 and for the embodiment of Figures 3 to 4 .
