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.
Claims18
An elevator car dome having an aerodynamically favorable shape for reducing airflow noises when mounted on an elevator car travelling at high speed, the elevator car being supported in a frame having upper and lower transverse yokes adjacent respectively a roof and a floor of the elevator car comprising:
- at least one panel of a flexible material;
- a supporting frame having an aerodynamically favorable shape, said one panel being attached to said supporting frame to form a wall of the dome;
- and
- means for attaching said supporting frame and said one panel to one of the upper yoke adjacent the elevator car roof and the lower yoke adjacent the elevator car floor.
An elevator car dome having an aerodynamically favorable shape for reducing airflow noises when mounted on an elevator car travelling at high speed, the elevator car being supported in a frame having upper and lower transverse yokes adjacent respectively a roof and a floor of the elevator car, comprising:
- a wall of a flexible material;
- a supporting frame having a slightly truncated pyramide shape including a plurality of vertically extending ribs, said wall being attached to said supporting frame to form an exterior surface of the dome;
- and
- means for attaching said supporting frame and said wall to one of the upper yoke adjacent the elevator car roof and the lower yoke adjacent the elevator car floor.
An elevator car comprising:
- an elevator car having a roof and a floor, said elevator car being supported in a frame having upper and lower transverse yokes adjacent respectively said roof and said floor;
- a pair of domes, one of said domes being mounted on top of said roof and another of said domes being mounted under said floor, each of said domes having an aerodynamically favorable shape for reducing airflow noises when said elevator car travels at high speed;
- each said dome having at least one panel of a flexible and foldable foil material;
- and
- each said dome having a supporting frame with the aerodynamically favorable shape, said one panel being attached to said supporting frame to form an outer wall of said dome, one of said frames being attached to said upper transverse yoke adjacent said roof and another of said frames being attached to said lower transverse yoke adjacent said floor.
