  • Patent number: 7017938
    Abstract: A transport trolley for transporting goods and/or people, especially for transporting children. The trolley has a trolley frame including shoring elements and at least two wheeled devices provided on the frame and including wheels for rolling the transport trolley in a transport direction on a ground. One of the wheeled devices, as a front wheeled device in relation to the transport direction of the trolley, is arranged on the frame in front of the other rear wheeled device. The wheelbase between the front wheeled device and the rear wheeled device can be adjusted by means of an adjusting device on the trolley frame. Thereby, the wheelbase, i.e. the distance between a wheel of the front wheeled device and a wheel of the rear wheeled device, can be modified if necessary. When said transport trolley is pushed by a person, for example at a running pace, a longer wheelbase of the trolley is required for achieving the necessary tilting stability.
