The individual edges (a,b,c) are provided in radius or ellipse form going out from the bottom edge in upward direction at an angle. The individual edges have different edge heights, gaps and contours. Two or multiple edges are individually or together in combination located in an angle. The edge combination is formed of metal or of composite materials, like metal and plastic material.
