ABSTRACT:
A racquet for use in playing tennis and other ball and racquet games has a stringing pattern which comprises a pair of longitudinal central strings (5') located symmetrically one on each side of the central longitudinal axis of the racquet frame, and four additional strings disposed outwardly of each of the central strings. The stringing pattern also comprises a pair of transverse strings (5") located symmetrically one on each side of the central transverse axis at a distance of approximately 40% of the length (L) of the strung surface as measured from the inner edge of the racquet throat (3). Also, both in directions toward the tip of the racquet frame (6) and toward the throat (3) four additional strings are arranged. Additional longitudinal and transverse strings are provided that are arranged outwardly from the aforementioned strings. An effective strike area is constituted by the cross-linking of the ten longitudinal and ten transverse strings corresponding to the scope of that area, the inner edges of the frame tip (16) and of the throat (3) being parallel and of identical curvature and the inner edges of both sides of the frame being arranged at minimum curvature.
