  • Patent number: 6279925
    Abstract: A method and apparatus for providing a sled having independently steerable skis is provided. The apparatus provides a sled having skis that move in three distinct directions in response to a single control input. Each of the skis is independently controlled, and can be used in combination or individually to control the movement of the sled. The sled may be provided with a seat for carrying a human occupant, or alternatively may be remotely controlled using extended levers, or servo motors operated remotely, such as by a radio frequency remote controller. The method of the present invention comprises controlling a sled by providing a control input to a first ski of a sled, wherein the control input simultaneously pushes down the ski in relation to the frame, rotates a forward end of the ski towards the center of the sled, and rotates the ski about its longitudinal axis such that an outside edge of the ski moves towards the frame of the sled and an inside edge of the ski moves away from the sled.
