<p>The invention concerns a method of joining the parts of rolling stools of the type comprising a hollow truncated body (1) with retractable roller elements and prolonged into a tripod constituting the seat (8) of the stool and the second step of a ladder, the first step of which is the upper base of the truncated body. There is disposed close to the edge of the upper base of the truncated body, flanges (2) formed in such a way that they constitute a cantilevered edge (3) provided with inwardly inclined lugs (4). A lower horizontal section (5) closing the base of the C-shaped profile constituting each of the legs (5) is provided with suitably dimensioned windows (7) placed in a correct position so that they correspond with the lugs during coupling of the lower horizontal section of the legs below the flanges, which lugs fit into and are retained by the windows. <IMAGE></p> |
