  • Patent number: 5280935
    Abstract: A footboard of a skateboard is with respect to a respective reference plane which at riding straight (=x plane) is parallel to the riding path (=the ground), and at turning (=x" plane) is with respect to the direction of riding slanted to one or the other side, is rhythmically swung around a longitudinal axis (O) of swinging lying in suspensions (4, 5) of the skateboard. The amplitude (A) and the frequency of swinging are mutually coordinated in a manner that swinging does not result in such meandering of the skateboard, which was felt inconvenient.To a socket shaft housing (8) of a suspension (4, 5) of the skateboard, said housing encasing a roller shaft (11), there is to each end thereof attached a gearing (9, 10), the gearings designed mirror-symmetrically.
