  • the device for detecting the marks can be a lamp, a first light guide cable and a second light guide cable exhibit.
  • the illuminant feeds light into the first Fiber optic cable. That over the first fiber optic cable transmitted light hits the rope and then depending on the existence of a brand more or less strongly reflected on the second fiber optic cable.
  • the second Light guide cable transports the reflected light to you any place.
  • the first and the second light guide cables are advantageous arranged in parallel near the rope.
  • the marks are advantageously over the rope distributed that a detection of one of the brands of a position corresponds to the elevator car at which the elevator car is accessible.
  • the first and second fiber optic cables are each one Are mono conductors.
  • the Device for detecting the marks of a lamp and a photosensitive element in the immediate vicinity of the Rope are arranged.
  • a display unit provided on one of the photosensitive element remote location and is arranged with the photosensitive Element is connected.
  • an electrical energy source can be provided be connected to the illuminant if necessary.
  • the one generated by the illuminant hits Beam of light at an acute angle on the rope.
  • the lamp can advantageously be pulsed Send out light.
  • the above-mentioned embodiments can be used as illuminants a light emitting diode, a laser diode or a Have lightbulb.
  • the color of the light emitted by the lamp can advantageously matched to the color of the brand be that the brand can be optimally detected.
  • the device for detection of the marks near the speed governor pulley or near the speed limiter to arrange yourself. This creates a constant distance between the device for detecting the marks and the Brands themselves guaranteed what to do when arranging the Device for the detection of the marks in the shaft not without further would be the case.
  • each one of the devices for detecting the Position of an elevator car is assigned to a rope and the ropes are coded with marks.
  • Identical devices for Position detection can be used.
  • FIG. 1 In the overall view of an elevator installation shown in FIG. 1 is in an elevator shaft 1 by means of an electrical Drive 2, which is connected to a traction sheave, via a suspension cable 3 moves an elevator car 4.
  • an elevator car 4 For surveillance the speed of the elevator car 4 is a speed limiter 5 provided, the limiter rope 7 with the Elevator cabin 4 is connected. The limiter rope 7 overflows a pulley 6 and the speed limiter 5.
  • the elevator car 4 is to be positioned in this way in the event of an evacuation - if necessary manually - that possibly included People leave the elevator car 4 more or less comfortably can.
  • the stopping accuracy of the elevator car 4 on the Floors play a subordinate role.
  • the device according to the invention for Detection of the position of the elevator car 8 provided, the Detector 8 in Figure 1 near the speed limiter 5 is arranged.
  • the Detector 8 of the detection device according to the invention the position of an elevator car 8 also near the Deflection roller 6 may be arranged.
  • Via a connecting line 9 (Fiber optic cable / electrical line) is the detector 8 with a display unit 10 connected.
