Foldable/Mobile Skate/Snowboard Performance Half Pipe Ramp

Abstract

The enclosed invention is a portable professional regulation size skate board and snowboard half pipe park. The park is made up of two mobile trailer units. Each unit consisting of a quarter ramps, performer platform with safety railing and a weather canopy cover. One unit consists of spectator platform and spiral staircase for climbing to the platform. Each unit comprising of structural steel framing is mechanically operated using hydraulics to raise and lower the unit on the a axis and raise and lower the quarter ramps on V axis, safety rails followed by horizontal movement on the X and Y axis. Once placed, the units, facing each other in a parallel position, hydraulically raised, then quarter ramps lowered and then hydraulically moved in the horizontal position connecting the two individual quarter ramps to be mechanically attached providing a smooth surface transition as required for the professional skate board performer.

What is claimed is: 
     
         1 . Two foldable/mobile quarter round arched ramp assemblies comprising of two separate trailers consisting of structural steel framing, tires and wheels for mobility, with supporting structural steel framing with cross bracing supports with hydraulic outriggers, stabilizers and hydraulic lifts for raising both units with upper rider/public observation deck, with the upper public observation deck unfolded into positon hydraulically and supported by manually attached steel post supports raised and lowered using vertical screw jacks and foot pads, and lateral steel post bracing, supporting upper public observation deck platform and deck framing of wood or metal decking surface. 
     
     
         2 . Each of the ramps consists of three separate components having hydraulic, mechanical or manual operational means and methods, devices or elements to raise, lower and adjust the ramps components, decking, laterally or unilaterally providing a smooth transition between ramp components creating a full “competition regulation size” half pipe skate ramp which mechanically closes and folds to within the legal dimensions of the fifty United States highway laws and regulations; a lower horizontal ramp component with pivoting point connections to the quarter round ramp component with pivoting point connections to trailer brackets with a vertical upper ramp component with pivoting points at the two upper rider/public decks with pivoting movement allowing the curved ramp to be raised to the folded position; with all ramps consisting of a plurality of support ribs formed thereon extending from the underside of the horizontal ramp component decks, the deck of the quarter round ramp component extension ramp and the deck of the vertical extension ramp, a plurality of regularly spaced substantially support ribs formed under each of upper rider and public performance decks with foldable metal guard rail system from the top of the trailer with a metal spiral stair and rail system to the upper rider/public snowboarding observation deck. 
     
     
         3 . For snowboarding, the entire ramp deck surfaces is to be covered with a man-made synthetic fabric used in all season snowboarding parks for snowboard riders to perform and compete.
