ABSTRACT:
A steerable wheeled sport conveyance is disclosed employing a unique diamond shaped footprint especially adapted for riding at relatively high speeds over various types of terrain. A first set of singular in-line steering wheels are rotatably mounted on the opposing ends of an elongated frame in a manner that also allows one or both of them to pivot on a vertical axis, and a second set of parallel wheels are mounted in an opposing manner across the longitudinal tilt axis of the conveyance. The opposing parallel wheels are attached to corresponding struts, which in turn are independently pivotably mounted near the longitudinal centerline of the frame, and are rotatable in a plane perpendicular to the rotationary plane of the two sets of wheels. Side to side tilting motions of the frame relative to the opposing struts creates vertical displacements between them, thus providing the steering forces that are conveyed and connected to the axles of one or both of the in-line steering wheels.
