  • Patent number: 4915403
    Abstract: A skateboard has a frame (1) on which a petal (7b) is pivotably mounted. When the pedal (7b) is pressed down its movement is converted via a push rod (16), a crank (26) and a toothed segment (29) into a rotational movement which is transmitted to a gear train (2). The output pinion of the gear train (2) is fixedly connected to the shaft of the two drive rollers (4). The push rod (16), in each case via a ball-and-socket joint (19a, 19b), is connected to both the pedal (7b) and the toothed segment (29) so that the transmission of the drive force is ensured even during tilting of the pedal (7b) caused when riding around curves. This mechanically driveable skateboard has the same height as a conventional skateboard and enables relatively high speeds to be reached while retaining the diverse possibilities such as ease in negotiating curves and maneuverability.
