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. The cross-sectional area of the apertures in any groove is at least equal to the cross-sectional area of the associated ventilation slot.
