Abstract
An apparatus for reducing wind noises on elevator cars traveling at high speed includes domes with an aerodynamically favorable shape that are attached above the car roof and/or under the car floor. The domes are made of a flexible material attached over a supporting frame of rods or tubular air chambers. Closable openings in the dome walls permit evacuation of passengers and access to the car roof and the underside of the car.
