Abstract
A sports racquet has a head portion with an elliptical cross-section in which the major axis is oriented parallel to the string plane. Preferably, the racquet includes a pair of converging throat frame members, and a throat bridge, which also have elliptical cross-sections oriented parallel to the string plane. As an alternative to a conventional throat bridge, in which some of the main strings are secured to the sides of the frame, a power ring, which bows inwardly toward the strung surface, spans the throat area, and supports the all the main strings, which are wrapped therearound. The racquet provides improved playability for hitting spin shots, by reducing wind resistance and reducing the minimum required angle of incidence (making it easier to hit the ball). Also, the hoop strength of the racquet is increased, which is particularly advantageous when using a power ring, which needs to provide tension to all the main strings.
