II. SUMMARY OF THE INVENTION

Snowboarding has become an increasingly popular winter sport. Most of the country, however, does not have the capability of providing the appropriate environment for this activity to occur, either due to a lack of snow in that geographic region, or snow being unavailable during most of the warmer months of the year. Artificial snow has been provided to engage in this activity which costs a great deal of money to maintain and only limited use can be had because of space restrictions.

Oversized skateboards have also been provided which simulate snowboarding, but they are limited in their use to appropriate surfaces, either the streets, or a very fine dirt or sand. Theses boards usually have large diameter oversized wheels or provide the board with numerous lower wheels or a flexible upper deck.

The present board is intended to most closely simulate snowboarding by providing an oversized skateboard with an overall elongated oval configured deck having an upper surface to which front and rear bindings are attached and within which the rider stands and a lower surface attaching a lower mounting plate from which extends a front fixed wheel assembly having a first lateral contoured wheel, an adjustable middle wheel assembly having a second lateral contoured wheel, and a rear fixed wheel assembly having a third lateral contoured wheel, the adjustable middle wheel assembly slidably engaging two parallel longitudinal support tracks within the lower mounting plate between the front and rear wheel assemblies, the adjustable middle wheel assembly secured within the longitudinal support tracks by a securing means, the first and third lateral contoured wheels having a smaller central diameter than a central diameter of the second lateral contoured wheel, wherein either the second and third lateral contoured wheel may be in contact with level ground at the same time, or the first and second lateral contoured wheels are in contact with level ground at the same time, wherein travel over coarse off-road surfaces may be gained.

The primary objective of the off-road sports board is to provide a board simulating the sport of snowboarding on a surface not covered in snow. A second objective is to provided the board with the lateral contoured wheels having the first and third lateral contoured wheels smaller in diameter than the second lateral contoured wheel, the second wheel also extending lower than either the first or third wheels, allowing for tilting and a quick and smooth rotation of the direction of travel of the board while the rider's feet are set within bindings on the upper surface of the deck for quick turns and maneuvering. A third objective is to provided the each lateral contoured wheel to travel upon rough and uneven surfaces found on hills and trails as well as pipes, streets and places suitable for a skateboard.
