  • Patent number: 7547037
    Abstract: A pull cart comprising a frame (H, 12, 13, 14), a flexible carrier structure (20) connected to the frame, and a suspension (30, 31) connected to the frame. The frame comprises a first (11) and a second (12) substantially U-shaped frame part. The suspension comprises a first suspension part (30) connected to the first frame part and a second suspension part (31) connected to second frame part. The first frame part can hinge relative to at least the second frame part about an axis (3) extending substantially parallel to the bottom of its U-shape. In a folded-out operative condition, on the one side, the suspension is connected to the frame such that forces introduced through the first and second suspension parts force the first and second frame parts apart, and, on the other side, the flexible carrier structure connects the first and second U-shaped frame parts such that the first and second frame parts are prevented from pivoting beyond said folded-out position.
