  • Publication number: 20100090425
    Abstract: A stand-on recreational personal vehicle device for sliding. The device may be used for sliding on ice or snow in activities resembling skiing or snowboarding. The device includes one or two boards, two foot straps for holding down feet of the rider to the boards, one or two foot platforms for supporting the feet of the rider, and one or two risers for coupling the foot platforms to the boards and providing a distance between the foot platforms and the boards. When two boards are used, a spring connecting rod couples the two boards together. Pivot joints may be used to connect the rod to the boards, or to the foot platforms, that permit the two boards to move with respect to each other from a parallel position to an aligned position. The rod and the board may be adapted for twisting, bending or both.

  • Patent number: 6705630
    Abstract: The present invention provides an easy turning and highly accurate personal vehicle. This is accomplished by providing a frame with at least one hubless wheel, wherein the passenger's foot may be contained. As such, the foot may accurately and safely steer and at the same time provide support. According to a preferred embodiment, there may be a frame, a first wheel with a first foot support in a center portion and a second wheel with a second foot support in a center portion. Also, there may be a human powered drive mechanism that allows the foot to be in the center portion of the wheel and yet still capable of providing human power to the personal vehicle. In this way a human powered, stable, highly accurate and fast personal vehicle is achieved as never previously accomplished within the art.
