Patent ID: 7377532

Claim:
A scooter comprising: a base frame ( 2 ) having an upper surface; a first and a second wheel ( 3 , 4 ) in engagement with the base frame ( 2 ) to allow movement of the scooter; a motion-transmitting unit ( 8 ) associated with the base frame ( 2 ) to drive at least one of said wheels ( 3 , 4 ); at least one first and one second plate ( 6 , 7 ) separated from each other, superposed to the upper surface of the base frame ( 2 ) and movable in reciprocating manner between a point of minimum distance from the upper surface of the base frame ( 2 ) and a point of maximum distance from the upper surface of the base frame ( 2 ), said first and second movable plates ( 6 , 7 ) being active on the motion-transmitting unit ( 8 ) to allow at least one of said wheels ( 3 , 4 ) to be driven into rotation whereby enabling the scooter movement, the motion-transmitting unit ( 8 ) converting a reciprocating motion of the movable plates ( 6 , 7 ) into a rotatory motion applied to the second wheel ( 4 ) and comprising at least one deformable element ( 16 ) directly in engagement with the first and second movable plates ( 6 , 7 ) and also active on two free-wheels ( 20 , 21 ) to transfer the motion received through the deformable element ( 16 ) to the second wheel ( 4 ) in an alternated matter; means ( 12 ) for syncronizing motion of said first and second movable plates ( 6 , 7 ) comprising a fixed structure ( 13 ) emerging away from the upper surface of the base frame ( 2 ) and a deformable body ( 14 ), other than said deformable element ( 16 ), which is movable on the fixed structure ( 13 ) and is in engagement at its opposite ends with said first and second movable plate ( 6 , 7 ), wherein the first and the second movable plates ( 6 , 7 ) are hinged on the base frame ( 2 ) at a front region ( 1 a ) of the scooter in correspondence of a steering member ( 5 ) and are defined by elongated plates disposed in mutual side by side relationship along a longitudinal vehicle axis ( 10 ), so as to exactly define a support surface designed to receive a rider's respective feet, so as a rider can stand on the scooter keeping legs and feet closed to each other in side by side relationship.
