Definitions

  • the present invention relates to an elevator system having a car and a first and a second transport path for this car, wherein the direction of the first transport path is different from that of the second transport path, and a method for operating such an elevator system.
  • Elevator systems with different transport routes for a car usually have more than one shaft.
  • a cabin is transported, for example, in circulation operation between two shafts.
  • Conversion devices transport a cabin on at least two floors from one shaft to the other.
  • Such transposers are mostly used in elevator systems with more than two cabins with circulating traffic between two shafts.
  • Systems are also known in which a car is parked (temporarily) in another shaft by means of a transfer device.
  • In order to achieve a sufficient flow rate of the entire system in the above elevator systems with at least two cabins and at least two shafts must be occasionally in the horizontal direction, ie when converting the car from one shaft to the other, driven at speeds in the presence of persons would lead to a risk of injury.
  • An elevator system with the features of claim 1 and a method for operating an elevator system with the features of claim 8 are proposed.
  • Advantageous embodiments are the subject of the dependent claims and the following description.
  • An elevator system according to the invention has a car and a first and a second transport path for this car, wherein the direction of the first transport path is different from that of the second transport path.
  • the first transport path has in particular a vertical direction, the second transport path in particular a horizontal direction.
  • a signal generator is present, which indicates a change, in particular an imminent change of the cabin from the first transport path in the second transport path and / or vice versa.
  • a change from the vertical direction to the horizontal direction and / or a change from the horizontal direction to the vertical direction of a person in the cabin is indicated by means of a signal generator present in or on the car.
  • a signal generator present in or on the car.
  • a person located in the cabin can stabilize its position and in particular adjust to an imminent transport path change.
  • indefinite articles used such as “a cabin”, “a transport route” or “a signal generator”, do not mean “one and only one”, but an indefinite number, ie "a / e or more "express.
  • the signal transmitter or the signal transmitter output optical and / or acoustic signals. In this way, the hearing and / or visual sense of a person can be addressed.
  • an optical signal indicating the direction of at least one of the transport paths is output.
  • the respective direction of the transport path of a car can be displayed with a luminous arrow in the cabin, with a change in the transport direction, for example, additionally sounds an acoustic signal.
  • a change in the transport paths is displayed for a predetermined period of time before the change of direction takes place.
  • a signal indicating the change in direction may be output, such as a red flashing arrow indicating the direction of the next transport path.
  • the remaining time period before the actual change of transport routes should be approximately equal to or at least equal to the average reaction time of a person in the cabin. In this way, enough time remains for the person to stabilize their position.
  • the use of the invention is particularly advantageous for elevator systems in which the direction of the first transport path is vertical and the direction of the second transport path is horizontal.
  • first and second transport path are possible, so that the first transport path is horizontal and the second transport path is vertical.
  • any other directions of the transport routes are conceivable.
  • a second aspect of the present invention relates to the determination of a maximum speed and / or a maximum acceleration of the cabin after a transport path change. This aspect will be described below without loss of generality in connection with the explained signal indicating a change of the transport path direction. However, it is reserved to seek independent protection for this aspect of the invention hereof.
  • the maximum speed and / or the maximum acceleration of the car is limited to a predetermined value immediately after a change of transport routes.
  • This measure can serve, alone or in addition to the output of a signal described in detail above, in the event of a transport path change, a person stabilizing his position sufficiently to minimize a risk of injury.
  • the value of the maximum speed of a car after a transport path change is determined as follows: It is assumed that a person in the interest of his own stability in a moving cabin occupies a certain footprint on the cabin floor, primarily by the distance D characterized the two foot well centers.
  • the position of the center of gravity is selected by a person usually in the absence of external influence approximately centrally above the connecting line of the foot well centers, ie centrally within the foot distance.
  • a risk of injury is minimized, as long as this focus remains within the foot distance or within the imaginary connecting line of the two foot well centers, when an external effect, such as a change of transport routes, the person acts. If the center of gravity leaves the said area, a risk of injury due to camber or impact on the cabin wall or the like is high.
  • V max By choosing a sufficiently low target speed V max can be effected that an average awake person in the above-described standing position when a greater acceleration occurs is able to maintain their stability by timely force transfer to one or the other foot.
  • the accelerations can become arbitrarily large, that is to say, that it would be possible to accelerate from 0 to target speed and vice versa immediately.
  • the scenario considered here is therefore especially in the case of emergency braking, in particular in the horizontal transport direction, before.
  • person and cabin have a relative speed up to the target speed.
  • S V ⁇ T.
  • V max D / (2T).
  • the above-exemplified maximum speed can thus compensate for a person, for example, in case of emergency braking by force displacement, without being exposed to an increased risk of injury.
  • the present invention also relates to a corresponding method for operating an elevator system according to the invention, in which case reference should be made in full to the statements regarding the elevator system according to the invention in order to avoid repetition.
  • FIG. 1 schematically shows two shafts 9 of an elevator system, for example, a MultiCar system with at least two cabs in circulation mode.
  • a transfer device 8 shown here only schematically, takes over the transport of a car 3 from a shaft in the other shaft.
  • Another converting device 8 is present, but not shown here.
  • the cabins 3 shown may be different cabins.
  • FIG. 1 it can also be understood that snapshots are shown at different times of a car 3 in the elevator system 10.
  • a signal generator 4 which indicates a change of the car 3 from a first transport path 1, here in the vertical direction, in the second transport path 2, here in the horizontal direction. It is advantageous if, in this exemplary embodiment, the signal generator also indicates a change from the second transport path 2 into the first transport path 1, for example after passing through the conversion device 8.
  • the signal generator has two optical signals 5 and 6 in this exemplary embodiment.
  • the optical signal 5 indicates the direction of the respective transport path 1 or 2.
  • four directional arrows are thus provided, through which the respective vertical direction or horizontal direction can be displayed.
  • FIG. 1 shows the optical signal 5 of the lower cabin 3, the direction of the upward transport path 1, for example in green Color, on.
  • the optical signal 6 is not activated in this state.
  • the optical signal 5 indicates the corresponding direction of the transport path 2, for example in red.
  • the optical signal 6, for example, a red flashing light activated.
  • an acoustic signal can sound when the optical signal 6 is active. A person in the cabin 3 7 (see. FIG. 2 ) is thus signaled the change of direction associated with the change of transport routes, so that this person can assume a stable position in order to minimize the risk of injury.
  • the optical signal 6 can already be activated during this predetermined period of time in order to signal a person 7 the imminent change of direction.
  • said period of time is at least the average reaction time of persons 7 using the elevator system 10. Such average reaction times are known per se.
  • the predetermined period of time can also be selected to be greater, so that the direction change signal is indicated even before the conversion device 8 is activated. This can be done, for example, on the drive from the previous stop to the stop of the transfer device 8.
  • FIG. 2 shows very schematically and not to scale a in a cabin 3 of in FIG. 1
  • the person 7 takes in a normal elevator ride approximately in the direction of the transport path 1 (see FIG. 1 ) a certain footprint on the cabin floor, by the distance D of the two Footrest centers can be characterized.
  • the illustrated position of the person 7 is selected for maximum stability.
  • the center of gravity S of this person 7 is located approximately in the center above the imaginary connecting line of the two foot well centers.
  • the elevator system 10 or the converting device 8 contains a control device which makes a limitation of the transport speed of the car 3 on the respective transport path 2 according to the above statements. It should be emphasized in this context that under some circumstances the measure of speed limitation that has been devised may also be sufficient to minimize the risk of injury, without the additional signaling explained in connection with FIG. 1 would be necessary.
  • FIG. 3 shows a multi-stage braking process, as already described above, wherein the absolute speed v of the car and the relative speed vrel of a person relative to the car is plotted against time.
