<p>A system of mounting and assembling modular sets. It is based on a tube (1) of aluminium, supported by feet (2, 3) - also of aluminium. To allows assembly the upper part of the feet have semi-cylindrical caps (4) with two flats (5). The tube rests in these. The tube is fixed by flanges (6), with strengthening w webs (7), bolted on the flats (5) and can thus be pivoted in its seatings. The tube also locates seat side supports (8) which are fixed to the tube by similar semi-cylindrical fixings (9) and flanges (10). The seat side supports are right angles triangle in shape and can also be of aluminium.</p> |
