发明名称 TENNISSCHLÄGER MIT GROSSER GESAMTLÄNGE
摘要 <p>A tennis racquet has an overall length greater than 28 inches, preferably between 29 and 32 inches, an egg shape strung surface having a length of at least 14 inches, and a strung surface area greater than 95 square inches. The frame is of widebody construction and formed of a composite material so as to have a minimum weight per unit length. While the overall length is increased, the strung weight of the racquet does not exceed 300 grams, and the mass moment of inertia about the butt does not exceed 56 g-m2. The foregoing racquet produces a number of playing advantages, while maintaining a conventional mass moment of inertia about the handle and thus retain good maneuverability.</p>
