An apparatus for sealing a gap between an elevator car door and the associated car wall during car travel includes a sealing strip of resilient material with wall portions that can be reversibly stretched to bridge and seal the gap.

Device for sealing a gap between car door and car wall in an elevator car

Lighting equipment of an elevator car and a method for guidance of persons in an elevator provides a floor indication that communicates to the passenger, in a simple and clear manner, reaching of his or her destination floor, even in high buildings with numerous floors. The lighting equipment has a light source and a control of the light source, which produces a color effect relative to the floor indication.

Elevator car lighting equipment for guidance of persons

An elevator installation includes an elevator car that moves in an elevator shaft with shaft doors and which car has at least one car apron arranged parallel to a plane of a shaft wall at a shaft door side. A device for reducing noises generated by the air flow arising between the shaft wall and the car apron includes sound-absorbing material that is mounted at the car apron and at the shaft wall.

Elevator installation with device for noise reduction

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.
