SYSTEM OF ELEMENTS FOR COMPOSITION OF A STAIR AND A STEP COMPOSED WITH ELEMENTS OF SUCH SYSTEM

摘要

System (2) of elements (1) for assembling a displaced staircase (3,4,85) with outer stair trees (12-14) and inner stair trees (15-17) as well as steps (11), the part (54) of the rear edge (55) of an underlying displaced step (45) at the location of the outer steps (12-14) is vertically aligned with the front edge (50) of an upper step (45), possibly after an overlap (S) , while at the rear edge (55) the displaced steps (45) at the rear step trees (15-17) are provided with a widening (59) such that underlying displaced steps (45), seen in top view, extend below the concerning subsequent step (45) over a distance (V) that is greater than the aforementioned overlap (S).
