Abstract
The present invention provides a ramp having an underlying supporting structure and a ramp section having a unitary riding surface. The supporting structure includes a pair of side frames of similar shape. The two side frames are connected together by a plurality of crossbraces to form a supporting structure with an upper supporting surface generally having a desired shape of the finished ramp. It is generally flat and constructed to have enough flexibility to conform to the upper supporting surface of the supporting structure to provide the desired ramp shape while having enough stiffness to properly support the rider. The supporting frames are each provided with at least two locating tabs that project above the upper supporting surface of the supporting structure to engage corresponding notches in the ramp section. In this way, the ramp section can be initially installed on the supporting structure and will be held in place by the engagement of the tabs with the notches until the ramp section can be more securely fastened to the supporting structure. This self-locking mechanism allows one person to temporarily position and install the ramp section to the supporting structure so t…
