ABSTRACT:
A portable court boundary for a sport such as badminton or volleyball is formed of flexible cord or twine. The boundary is designed to be wound upon a specially constructed spool so that it can be easily unrolled and laid in place on the surface where it is desired to play the game. The spool has a hollow interior within which are stored hooks for anchoring the boundary to the playing surface. To assist in properly disposing the boundary, each of the boundary corners is color coded with a different color.
