ABSTRACT:
A balancing sport including an elongated platform for receiving a participant. A lower surface of the platform is attached to two sectors which ate rotatable about two shafts positioned along a common horizontal axis of rotation. Each shaft is secured about a sector post anchored to a horizontal planar board. The lower surface of the board is attached to a pivot means with the board being pivotable about a vertical axis of rotation. The pivot means is attached to a rectangular plank movable along a linear horizontal axis. The lower surface of the plank includes attached axles with wheels attached. Each wheel is positioned within track rails projecting perpendicular and away from the bottom surface of the plank. Each track rail extends longitudinally parallel relative to one another and the linear axis. The vertical axis is positioned in an offset location about the plank allowing an oscillation to occur when the platform is rotated about the horizontal axis, thereby permitting the platform to move laterally with little assistance from the participant. Elastic means attached about the front and rear of the plank tend to urge the plank toward a center location of the sport platform when used. Thus, the platform is revolvable about a horizontal and vertical axes of rotation, and is movable laterally along a linear axes.
