  • Patent number: 4826186
    Abstract: The hand trolley has a bottom frame equipped with a front pair of swiveling wheels, a rear pair of swiveling wheels and one or two non-swiveling central wheels located at a lower level than the plane defined by the front and rear pairs of wheels. The bottom frame of the trolley is constituted by two lateral bars and two central bars placed respectively on opposite sides of the longitudinal plane of symmetry of the trolley, the rear ends of the central bars being closer to the plane of symmetry than the front ends and the bottom frame being thus M-shaped when viewed from the rear. The central wheels are placed beneath the central bars while the front wheels are placed at the same location as the common front ends of the lateral bars and of the central bars, the rear wheels being placed at the same location as the rear ends of the lateral bars.
