  • the stair step elements can thus be connected without additional connecting means, in particular without screws or the like, to be assembled.
  • the assembly and disassembly of a staircase should be further simplified.
  • the staircase should be as simple and inexpensive to manufacture.
  • the same parts should enable different stair configurations.
  • the flight of stairs proposed for a staircase in particular for a modular staircase, comprises two parallel stringers at a distance from one another and step elements which are arranged between the stringers and are detachably connected to the stringers, each forming a step and a riser.
  • the step elements rest on first and second brackets, which are arranged on inner sides of the cheeks that face one another.
  • the cheeks Due to the step elements in between, the cheeks form real cheeks and not spars. This has the advantage that the step elements are positioned and held in their position by the lateral cheeks.
  • the step elements can thus be releasably connected to the cheeks by simply placing them on the brackets provided on the inside of the cheeks. This simplifies assembly and disassembly of the flight of stairs.
  • holding devices on the cheeks and/or step elements, which are expensive to produce can be dispensed with, so that they can be produced easily and inexpensively.
  • the stringers and step elements can be manufactured and kept in different dimensions, in particular lengths, so that the flight of stairs is scalable. Furthermore, several flights of stairs can be combined to form single or multi-flight stairs, with or without a landing, so that different stair configurations can be implemented.
