  • the step element has an approximately rectangular tread portion, on the end side two oppositely angled, the riser determining legs are integrally formed. These legs have mutually parallel slopes, forming the bearing surfaces for adjacent step elements. By moving along the inclined support surfaces of adjacent step elements, the step height and the length of the tread surface of a staircase can be adjusted continuously.
