Abstract:

This invention consists of a riding deck, adjustable bias block, flat spring, and two adjustable compression springs, and a pair of roller trucks that are fastened to the flat spring at opposite ends. When the rider stands on the deck and applies pressure to either side of said deck; there will be a directional change of the truck wheels. Depending on the weight of the rider, the distance between the top of the deck and the bottom of the truck wheels can e adjusted by increasing the tension on the two compression springs located at the midpoint of the flat spring. This increased tension on the compression springs causes the opposite ends of the flat spring to deflect away from the underside of the ridding deck. This unique design allows the flat spring to change from a static parallel flat configuration of an arc configuration. Now as the tension is increases on the compression springs, the distance between the underside and the bottom of the truck wheels which are at opposite ends of the flat spring increases. Due to the uniqueness the compression spring design, the rider in extreme maneuvers can tilt the deck so that the flat spring will change its position in relationship to the underside of the deck. The rotation of the flat spring along the axis of the underside of the riding deck is what helps a slalom rider achieve the tight down hill racing maneuver of darting in and out between a set of cones much like a downhill snow ski slalom racer. This maneuver with the flat spring changing its position allows the rider to lean his or her body at extreme angles and allow the truck wheels to stay planted on the riding surface.
