Abstract

Each oval section upright (1) has a flat inside wall containing openings (3) at regular intervals into which the rungs are inserted. The outside wall (4) of each upright has a longitudinal depression (5), a part of which is shaped so as to hold securely a band of flexible material which in turn is shaped so that it covers the opening to the depression (5) without completely filling it. The depressions extend longitudinally along the length of each upright. The rungs (7) are inserted into the openings (3) until they touch the outer wall of the uprights and are secured by two screws whose heads rest inside the depression. The band of flexible material (16) is then placed inside the depression (5) and completely hides the heads of screws.
