Definitions

  • a light barrier is known in which a light beam is placed perpendicularly in the closing line of the two-part cabin door.
  • the light transmitter is arranged above the door opening and the light receiver below the threshold.
  • This light barrier only offers insufficient protection, since people passing from the side are not detected during the closing movement. It is also possible that the door control is unnecessarily interrupted prematurely and time is lost.
  • a monitoring device for automatically closing elevator doors has features of the light barrier described above, but partially avoids the disadvantages thereof.
  • holes are arranged in the door threshold over the entire width of the door opening, into which lenses are inserted, through which the light of a light source can exit.
  • Two light receivers of a light barrier independent of the door position are attached symmetrically to the door closing line at a distance of about 30 cm at the upper edge of the door opening.
  • Two further light receivers, assigned to a light barrier dependent on the door position are attached to the upper edges of the doors. They should respond to obstacles near the door edge, for example in an area up to 75 mm.
  • the light barrier which is independent of the door position, it is disadvantageous that the door control can be interrupted prematurely.
  • Another disadvantage is the relatively expensive manufacturing costs of the door sill with the light exit openings distributed over the entire door width, and there is also the risk of contamination.
