  • Patent number: 5306208
    Abstract: An apparatus for ventilating the passenger space of a rapidly moving elevator car generates an air flow through the car during the travel of the car in an elevator shaft. A plurality of ventilation slots are provided one above the other and open to the passenger space of the elevator car and to a ventilation channel extending vertically in one wall of the elevator car. The total cross-sectional area of the ventilation slots is approximately twice as great as the cross-sectional area of the ventilation channel. The ventilation slots are formed by carrier slots in a sheet metal carrier on which a plurality of strips of a laminated material plate are attached on a passenger space side thereof and on which a perforated metal reinforcing plate is spot-welded on a rear side thereof. The reinforcing plate has rows of apertures formed in generally V-shaped grooves aligned with the ventilation slots. The grooves space the apertures from the carrier.

  • Patent number: 5228769
    Abstract: An elevator car has a passenger space bounded by a pair of side walls and a ceiling with a fluorescent tube attached to the ceiling and a ceiling frame suspended from the ceiling and supporting translucent filler panels. An opaque middle ceiling strip is attached to the ceiling frame between two of the filler panels and below and in longitudinal alignment with the fluorescent tube. A pair of spot lamps are attached to an upper surface of the middle ceiling strip and are exposed through holes in the strip to illuminate predetermined areas of the side walls containing destination floor actuating elements and information panels for the floors. The middle ceiling strip has one side rotatably attached to the ceiling frame by a hinge connector for providing access to change the fluorescent tube and the spot lamps. The strip also is releasably retained by a locking bar on the other side thereof which engages the ceiling frame and can be released with the aid of a simple tool.
