Abstract:
1. An elevator car comprising: a car-platform having a car-floor plate and several platform-sections including a front platform-section and a back platform-section arranged on a central platform-section, wherein the central platform-section of the car-platform is constructed as a safety-plank of the elevator car and upper surfaces of the front platform-section, the back platform-section, and the central platform-section are configured to lie in a common plane and receive the car-floor plate; and platform-edge sections mounted over two side-edges of the car-platform, which platform-edge sections extend over, and are fastened by fastening means to, upper surfaces of all the platform-sections, wherein mounted on or in the central platform-section constructed as a safety-plank is a safety gear, and wherein the platform-edge sections have a cross section and are of a material such that the edge sections can absorb bending stress which a load in the car exerts on the platform-sections extending beyond the central platform-section and thereby undergo a flexure of less than 1% of a length of the platform-sections, and the platform-edge sections are made of one of steel and an aluminum alloy and each have a cross section which, relative to a horizontal axis of gravity of a corresponding platform-edge section, has a geometric moment of inertia of at least 50 cm
