Abstract
A knock-down quarter pipe for bikers, skateboarders and in-line skaters has a base, and a plurality of legs extending up from the base, the legs having lower ends lying in a common plane. A deck is supported by the legs at a selected elevation above the base, the deck having front and rear edges and a surface extending between those edges that is substantially parallel to the plane. A ramp extends from the front edge of the deck down to the plane, that ramp having a lower leading edge that is located in that plane and spaced in front of a base. Preferably, the base and at least the lower end portion of the ramp may be filed with a fluid medium to add weight to and lower the center of gravity of the quarter pipe. Preferably also, a rigid coping rail is located between the front edge of the deck and the ramp which can function as a grind rail.
