  • Patent number: 5971419
    Abstract: A rotational boot binding for mounting on a free style snowboard. The binding allows the user of the snowboard to wear hard shell boots and while boarding rotate both feet in a vertical plane for shifting his or her weight to the toe or the heel of the board. The binding includes a base plate having a plurality of holes therein for attaching and adjusting the base plate at an angle from 30 to 120 degrees to an axis along a length of the snowboard and centered thereon. The base plate is attached to a foot plate by a horizontal pivot pin. The pivot pin allows the foot plate to rotate on the base plate in a vertical plane thereby allowing a shift of weight to the toe or to the heel of the snow board and thus control the movement of the snowboard. The binding includes a toe base plate, a toe foot plate, a heel base plate and a heel foot plate. By having separate toe plates and heel plates, the binding can be adjusted on the snowboard for a wide range of different lengths of boot.
