  • Patent number: 7967313
    Abstract: A wheeled vehicle includes a pair of leg driven skis and hand operated levers for simultaneously applying power to a crank and drive sprocket to propel the vehicle. A pair of controllers, one at the top of each thrust lever, include handles that are pushed and pulled to reciprocate the levers and may simultaneously be rotated through wrist and forearm action to steer the vehicle. Auxiliary steering is provided through a handlebar mounted to the vehicle separately from the thrust levers. The skis are operatively coupled to their associated levers, either directly through a pivotal connection or indirectly through an elongate link rotatably coupled at one end to the lever and at the other end to the ski.
