ABSTRACT:
A sports racket which is made by joining longitudinal sections of a racket, particularly half sections of a racket, along a plane parallel to the center plane through the playing surface of the racket. The longitudinal sections of the racket define recesses to form hollow spaces within the interior of the racket upon joining of the racket half sections to thereby reduce the weight of the racket while maintaining its strength. This racket construction is also combined with a string suspension system which includes strings which are splayed to alternately contact the racket frame in front of and behind the plane of the playing surface, contributing to the strength and integrity of the frame.
