The tubular chassis (1,2) comprises two parts, the first (1) forming the seat and the second (2), inclined part, for receiving the bin (13,14). A front wheel (4) is fixed on a vertical axle (3) and there are two main rear wheels (6) of diameter greater than the front wheel (6). Each rear wheel (6) has two rollers (10) mounted on a curved arm (11), pivoted (12) near the main wheel axle (7) which is fixed to an arm (8) at the lower end of the second part (2). The second part of the chassis is formed from two parallel parts (41,42). The first part (41) has support arms (15,17) for the bin (13,14). These arms are pivoted (16,18) to move from an unfolded position, where they extend perpendicular to the part (41), to a folded position when the extend parallel to this part. ADVANTAGE - An ergonomic design offering useful transportation capacity and ensuring stability of the cart.
