Abstract

Abstract A sporting game comprising a ball which can be hit between game players positioned on a fixed court. The ball consists of two coiled strips of a lightweight material, each of said strips defining a plurality of coils and each of said coils of a first one of said strips being perpendicular to the planes defined by the coils of a second one of said strips, at least one of the coils of said first strip being positioned between adjacent ones of said coils in said second strip, at least one of the coils of said second strip being positioned between adjacent ones of said coils in said first strip, said first and second strips being secured together at right angles to each other at a predetermined area. The players, in a preferred embodiment, attempt to hit the ball over a net by means of special disc-like paddles.
