Patent ID: 7832742

Claim:
A sportboard comprising: a. a board body having a longitudinal axis and a substantially planar midsection; b. a left foot mounting assembly comprising: i. a left base plate comprised of a left bottom surface joined to the board body and a left top surface tilted at a first rightward acute angle with respect to the left bottom surface; and ii. a left rotatable plate comprised of a left lower surface pivotably in contact with the left top surface of the left base plate, and a left upper surface tilted at a first leftward acute angle with respect to the left lower surface, the left rotatable plate being rotatable from a neutral position clockwise and counterclockwise with respect to the left base plate; and c. a right foot mounting assembly comprising: i. a right base plate comprised of a right bottom surface joined to the board body and a right top surface tilted at a second leftward acute angle with respect to the right bottom surface; and ii. a right rotatable plate comprised of a right lower surface pivotably in contact with the right top surface of the right base plate, and a right upper surface tilted at a second rightward acute angle with respect to the right lower surface, the right rotatable plate being rotatable from a neutral position clockwise and counterclockwise with respect to the right base plate; wherein the first rightward acute angle of the left base plate is substantially larger in magnitude than the first leftward acute angle of the left rotatable plate and the second leftward acute angle of the right base plate is substantially larger in magnitude than the second rightward acute angle of the right rotatable plate such that when the left rotatable plate and the right rotatable plate are in their respective neutral positions, the left upper surface of the left rotatable plate is tilted rightwardly in the direction of the longitudinal axis of the board body at an angle equal to the difference between the first rightward acute angle and the first leftward acute angle, and the right upper surface of the right rotatable plate is tilted leftwardly in the direction of the longitudinal axis of the board body at an angle equal to the difference between the second leftward acute angle and the second rightward acute angle.
