The invention concerns an undercarriage (1) for a manually displaceable cart, particularly a shopping cart with a frame base (3), which is trapezoidal when viewed from the top, with at least three wheels (2, 2'), the longer parallel side of which is missing, and supports (15) rise upwards for receiving a basket or container, and the frame base (3) essentially is constructed of at least two wires (9, 10) arranged one on top of the other, which are welded together by means of intermediate pieces (13) and/or by means of raised areas in the wires (9, 10). The supports (15), with their ends pointing downward (16), cross over the two wires (9, 10) arranged on top of the other. In addition, in the rear area (4) and on the lower wire (10) of the frame base (3) and on both longitudinal sides (6), in each case one outwardly directed loop (12) is formed for mounting in each case one wheel (2, 2'). On the frame base (4) at both sides of the loops (12) between the frame base (3) and the wheels (2, 2'), spacer plates (18) are arranged which have both a vertical opening (19) for mounting of a mounting device (22) for fastening a wheel (2, 2') and provide supporting surfaces (20) which are supported by the projections (17). The spacer plates (18) are held in place on the frame base (3) by the fastening devices (22) for fastening the wheels (2, 2'). It is proposed to construct the spacer plates (18) so that each of their supporting surfaces (20) constitutes an angle smaller than 180 DEG . |
