Abstract: The present invention relates to a self propeller skateboard (10) comprising upper deck (12A) pivotally mounted on a drive shaft (22) having a left drive wheel (18L) securely fastened at a left distal end and a right drive wheel (18R) securely fastened at a right distal end. The drive shaft (22) is mounted in a transmission (14) which is self propelled by a user by shifting his weight from an upper deck front (12AA) to an upper deck back (12AB) and vice-versa. When the upper deck front (12AA) is raised, a front cable (26F) is unwinded from the drive shaft (22) by rotation thereof. The drive shaft (22) is further rotated when the upper deck rear (12AB) is raised, a rear cable (26R) is unwinded from the drive shaft (22).

Abstract: Spaced frame rails mount a U-shaped frame therebetween, wherein the U-shaped frame is pivotally mounted relative to a first axle mounting a first wheel at a first end of the side rails, with a second axle mounted at the second end of the side rails supporting a second wheel. The side rails include extension legs extending from the side rails mounting a spool axle, with the spool axle mounting a first spool wheel that is mechanically coupled to the U-shaped support frame by means of a first string, with a second string directed from a second spool wheel on the spool axle to a third spool wheel mounted to the second axle, that in turn includes a ratchet and pawl structure, whereupon pivoting of the U-shaped frame rotates the first and second spool wheels as well as the third spool wheel to effect rotation of the ratchet and second axle effecting propulsion of the roller skate structure.
