Abstract
A shopping trolley (10) has a basket (11), handle (12) and front and rear wheels (13, 14). The basket (11), tapered in plan view, has side walls (15, 16) interconnected by a front wall (17). The rear wall (19) is hingedly connected to the side walls (15, 16) and engages the rearward end of the floor (22), which is hingedly connected to the side walls (15, 16) or front wall (17). The floor (22) is downwardly inclined from the rearward end to the forward end. When the trolley (10) is nested with a similar trolley, the rear wall (19) is swung inwardly and upwardly, causing the floor (22) to be swung upwardly to be behind the front wall (17). Alternative the floor (22) may be folded e.g. in a concertina-like fashion, to be behind the front wall (17).
