Elevator car and an elevator

摘要

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.

主权项

1. An elevator car comprising a car box and a suspension device configured to support the car box in an elevator hoistway, the car box comprises:
an interior for receiving and transporting freight and/or passengers, said interior is bounded by at least a floor, walls, a roof, and a door arrangement, a floor element, vertical beam elements, and roof beam elements, which said floor element, vertical beam, and roof beam elements are connected to each other such that they form a load-bearing frame structure of rectangular prism shape, a plurality of planar elements of rectangular shape on an inside of said load-bearing frame structure fixed side-by-side to said load-bearing frame structure and extending essentially from one edge side of the car box to another, from which plurality a uniform wall surface and/or roof surface of the car box is formed, wherein said load-bearing frame structure and/or said planar elements comprises one or more sandwich beams and/or plate elements comprising a first skin and a second skin and one or more core elements, wherein said one or more core elements are formed from said first skin by cutting and bending or by punching along cutting edges of said first skin towards said second skin, said cutting and bending or punching forming an opening in said first skin, and joining said first skin to said second skin by said one or more core members, wherein said first skin has edge surfaces, and wherein said one or more core elements is spaced apart from said edge surfaces.
