An elongate detector strip is mounted on the outer face of respective car doors adjacent the leading edges thereof. A pair of opposing landing walls support respective ones of two sliding landing doors. The landing doors are synchronized to open and close with the car doors by control circuitry. The detector strips together define three separate regions in which detection of an obstruction can take place namely, a column like region extending across the leading edges of the car door and the landing door a column like region extending across the leading edges of the car door and the landing door, and a planar region extending vertically between the detector strips. |
