Patent ID: 7562894

Claim:
A pair of gliding boards adapted to be used together by a user, with no connection from one of said pair to another of said pair during use of the pair of gliding boards for gliding in a gliding direction, said pair of gliding boards comprising: a first gliding board having an elongated shape extending along a first longitudinal axis, said first gliding board having a first arrangement for fastening the user's left foot to said first gliding board along a first fastening axis; a second gliding board having an elongated shape extending along a second longitudinal axis, said second gliding board having a second arrangement for fastening the user's right foot to said second gliding board along a second fastening axis; the first fastening axis forming a first angle β 1 with the first longitudinal axis; the second fastening axis forming a second angle β 2 with the second longitudinal axis; the angles β 1 and β 2 extending from respective ones of the first and second longitudinal axes in the same direction; at least one of the angles β 1 and β 2 is non-zero; the first gliding board having an outer periphery defined by a closed curve passing through a left shovel point, a right shovel point, a left tail point, and a right tail point; each of said points constituting a concavity/convexity inversion point of said contour; a portion of the contour connecting the left shovel point and the left tail point being a left sidecut, said left sidecut being concave; a portion of the contour connecting the right shovel point and the right tail point being a right sidecut, said right sidecut being concave; a straight line passing through the left shovel point and the right shovel point forming, together with said first longitudinal axis, a clockwise or counterclockwise angle δs not equal to 90°; a straight line passing through the left tail point and the right tail point forming, together with said first longitudinal axis, an angle δt oriented in the same clockwise or counterclockwise direction as the angle δs, said angle δt not being equal to 90°.
