  • Patent number: 10532910
    Abstract: An exemplary elevator system includes an elevator car having an integrated cabin and car frame structure including a platform thickness between a floor surface in the cabin and a lowermost surface on a support beam used for supporting the car beneath the floor surface. A sheave assembly is supported beneath the floor surface. The sheave assembly includes a plurality of sheaves and a plurality of subframe beams. The sheaves and subframe beams fit within the platform thickness such that the subframe beams and the sheaves are no lower than the lowermost surface on the support beam. A plurality of isolation members are between the sheave assembly and the elevator car for isolating an interior of the cabin from vibrations associated with movement of the sheaves.

  • Publication number: 20020139619
    Abstract: An elevator system includes an elevator car and a counterweight installed in parallel with an outer wall of a building. The system is mounted to a single wall and can be installed into preexisting, multi-floor structures which have been constructed without an elevator hoistway. To move the car between floors, a drive assembly is mounted to a structural beam attached to the outer wall. The structural beam extends from the outer wall and is at least partially supported by the elevator car guide rails.

  • Patent number: 5564529
    Abstract: An elevator car includes a car frame and a platform assembly having a composite platform and a support frame. The composite platform includes upper and lower metallic sheets with a oriented strand wood layer therebetween and bonded to the sheets. The support frame includes a perimeter structure and a pair of centrally located stringers. The composite platform is rigidly attached about its outer edges to the perimeter structure and extends unsupported between the centrally located stringers and the perimeter structure. In a particular embodiment, the elevator car includes a door frame extending from the car frame and platform assembly and which is isolated from the cab of the elevator car.

  • Patent number: 5325937
    Abstract: The vibrations of an elevator are attenuated between the elevator and a cab by providing an elevator frame disposed in a first plane and a platform in a second plane, the platform being suspended from the frame by a plurality of side braces extending therefrom. A vibration attenuator is disposed directly between each side brace and the platform to attenuate vibrations that may pass between the frame and the platform.
