  • Patent number: 9617120
    Abstract: An elevator car includes a suspension device for supporting the elevator car in the elevator hoistway and a car box. A floor, vertical beam, and roof beam elements form a load-bearing frame structure of the car box. A plurality of planar elements of rectangular shape are fixed side-by-side to the frame structure and extend essentially from one edge side of the car box to another. The frame structure and/or said planar elements of said car box comprises one or more sandwich type beam and/or plate elements comprising a first skin and a second skin and one or more core elements. The core elements are formed from the first skin by cutting and bending or by punching through one or more core members from the cutting edge of the first skin towards the second skin and by joining the core members to the second skin of the beam and/or plate element.
