  • Inline skateboard with differentiated wheels
    Patent number: 8915506
    Abstract: “INLINE SKATEBOARD WITH DIFFERENTIATED WHEELS’ that has wheels with different predetermined sizes being affixed by means of two trucks to the shape. Besides the wheels, the two trucks have a shock absorber device, a metallic base structure and a torsion system for the execution of curves with the automatic alignment of the wheel sets with the shape after turning movement completion. Thus, the movement is limited by three features combined: the size of the internal wheels, the sliding of the internal screw through the aperture of the wheels axles' fixation support and the sliding of the intermediary parts of the recesses of the torsion device mortise aperture with the wheels axles' fixation support relative to the sleeve apertures.
