ABSTRACT:
A modular series of square or tubular rails are joined to together by rigid or flexible connectors to provide a playing surface in-line skates and skateboards. The rails are separated from the earth or other surface by support columns. The rails themselves can be straight, curved, or can be equipped with a number of bends. Single column supports are preferred for permanent installations where the column can be bolted onto a surface or can be partially buried in the earth. Dual-column supports that form a triangular pattern that enable the rails system to be portable, yet allows skaters to impart horizontal as well as vertical loads on the rails safetly. Both columns allow the use of tubular or rectangular rails. Joints between the rail may be flexible to allow a broader range of skating maneuvers.
