ABSTRACT:
A racquet in which the area of the string which manifests relatively true rebound of the ball, the so-called "sweet spot", is maximized. To achieve this condition the strings are so tensioned or so structured that the deflection produced by impact of the ball near the outer periphery of the racquet is substantially equal to the deflection near the center of the racquet. The strings are subjected to lower tension near the outer periphery than near the center of the racquet or they are of smaller thickness near the outer periphery than near the center or they are differently irradiated. So as to achieve the different tensions with strings of a given diameter, a plurality of separate short string lengths are used.
