  • Arrangement in a wheel lifting mechanism
    Patent number: 7036185
    Abstract: The present invention relates to an arrangement in a wheel lifting mechanism designed to lift at least one wheel (1) running on an underlying surface so that it is capable of negotiating an obstacle (h) rising above the underlying surface. The arrangement comprises an element (7) which is formed with a contour convexly curved towards the underlying surface and is moveably supported in relation to the axle of the wheel (1). The said element is designed, when the contour of the element (7) engages with the obstacle (h), to bring about the said lifting of the wheel (7) as the element (7) is rotated about its point of engagement with the obstacle (h). The arrangement further comprises a chassis (4), to which the wheel axle is firmly connected.
