Abstract

A motorized skiboard includes a skiboard having a central opening with a drive belt mounted in said central opening and driven by a motor and encased and held in a drive belt housing. First and second foot mounts rest on said housing on either side of said motor. The first foot mount is mounted on a piano hinge and is connected to a throttle cable so that pivoting the foot mount controls the motor. The drive belt is formed from a plurality of trapezoidal linkages with pivotally attach drive bars. When the motor is moving the belt at a speed greater than the speed at which the board is moving (when the belt is propelling the skiboard) the drive bars pivot into a ground engaging position. However, when the skiboard is sliding downhill and moving faster than the speed of the belt the drive bars pivot into a non-ground engaging position permitting the board to freely slide down the slope of a hill.

Dependent claims

A motorized skiboard comprising a skiboard having a top plane, a bottom plane and a central opening extending through said top plane and bottom plane, a motor drive belt, drive belt mounting means mounting said drive belt centered relative to said opening

a throttle means adapted to control said motor;
said drive belt including a plurality of drive bars, pivotally mounted to said belt whereby said belt is mounted relative to the board so that said drive bars extend beyond the bottom plane of the board when in ground engaging position and ride at the bottom plane of the board when in a sliding position;
wherein said drive belt comprises a plurality of trapezoidal links, each trapezoidal link having a downwardly extending arm and a land portion and an upwardly extending arm and
said drive bars having a planar portion and a plurality of vertically inclined arm portions pivotally attached to said trapezoidal links whereby when said drive bars are in a sliding position said arm portions of said drive bars are parallel to the downwardly extending arm portions of said trapezoidal links and said planar portion of said drive bars are parallel to and resting against said land portion of said trapezoidal link;
and whereby when said drive bar is in a ground engaging position said planar portion is perpendicular to the land portion of said trapezoidal links.
