[0004] 2. Description of the Related Art

[0005] Skateboard have became very popular in the last years for sports and exercises specially in young generation participation, the skateboard that actually we know and the problem that represent to skaters due to the unfavorable conditions of roads surfaces are only some of the reasons for which we present our version of this skateboard present invention, since, they will be to stimulate and to correct the technical problems and those of performances, also, the current skateboard they don't only represent a problem from road surface conditions due to the designs of complex subduing systems, but they rather present technical problems and physiques for the skaters in general, this above problems and many others we will solve with our skateboard present invention.

[0006] The original idea of the skateboard it was to imitate the surfboard patterns technology, adding a plurality of wheels mounted on the underside longitudinal axis of the board or deck with two front and rear wheeled mechanisms known as trucks, this said trucks devices systems it's mounted to the deck an supporting the pivoting shafting dynamics of the skateboard, the central longitudinal axis of the classic skateboard platform deck are completely made with a flat characteristics and the both front and rear ends of the deck are bent upward without mentioning any others characteristics of platform sizes, board or deck materials construction modes, wheels composition and all combinations of parts and components involve in the conventional skateboard quality and performances.

[0007] The findamental real problem with the conventional skateboards in particular the classic skateboard mentioned before and all types of new improved skateboards systems available today likes in-line roller skateboards with or without rotatable or steerable alignment, tandem mounted or plurality of in-line wheels arrangements with all front and rear wheels combinations, all others types of skateboards which includes mounted control devices likes brakes or manually steering the wheels or brakes, different sizes of wheels configurations under the platform, supporting mechanical devices, steerable platform for wheels steers, all classic skateboards with longitudinal mounted trucks devices in all combinations with or without rotatable front or rear trucks configurations we denominate the “Concept of Skateboarding Patterns”, that means the differences between those conventional or improved skateboards mentioned above and our skateboard related in this present invention, this concept of skateboarding patterns on wheels are specially related to skateboards who support any type of trucks devices and all system mounted on, excepting our skateboard presented in this invention which has a new aerodynamic deck design, high technology concept and state-of-the-art integral independent suspension and rolling devices systems, all parts and components without trucks devices allowing to this system to be the skateboard who has the highest performances and new concept of total extreme skateboarding choices with the superior capability and stability in all surface conditions providing aerodynamic new design and high quality smoother-rides, higher, faster and longer jumping acrobatics free-style forward and lateral sliding technique maneuvers that the conventional most popular four wheeled trucks-on mounted skateboards.
