<p>The hand baggage trolley folds into a package, having a folding handle with grip. A rear assembly is extensible and folds laterally, with a first slide working on the handle. A pair of bars hinge on opposite sides of the slide. A bottom assembly has one or more bars hinging at the bottom of the handle, and pivots on the rear assembly at the bottom at three equidistant points. It folds and extends laterally with the rear assembly, unfolding into a position at right angles to the latter. Either the rear or bottom assembly or both are in the form of a double cruciform frame with a pair of handle bars hinging on the rear part of the handle at opposite sides. Cross-bars intersect the handle bars at the centre, and are joined together at opposite ends so as to form the two cruciform frames side by side.</p> |
