The trolley which has castors (22) and a pivoting grille comprises a pivoted cross shaped base (1) with two sides (5,6) and two inverted U uprights (8A,8B). Each upright has an end part (12A,12B) fixed to an end (5A,5B) of one of the base sides and another end part (15A,15B) free to be fixed to one end (6A,6B) of the other side of the base. The first end parts (12A,12B) of the upright fit in sockets (10A,10B) in which the end can pivot and slide. The second ends of the uprights are fitted in a socket housing (14A,14B). Sockets (20A,20B) on the base each engage the second ends of the each upright to lock the base in the folded configuration. |
