The legs have three pairs of legs (2,11,23,31,42,51) and each pair are joined in the middle to form a cross (1,21,41) that can fold up. The lower ends of each pair of bars are articulated on the lower ends of adjacent bars to form two legs in contact with the ground. The upper of each pair of bars are articulated on the upper ends of adjacent bars to form two support zones for a table top. The bars are made of flat metal and their end parts are twisted in opposite directions and hold the axles (60-66).
