发明名称 Improved racquetball racquet construction.
摘要 <p>The improved racquet (1) has a strung surface (11) which is larger in area than the strung surface of a conventional racquet, and in which the strung area (11) is both larger in length and width than the strung area of a conventional racquet. However, the overall weight and balance of a conventional racquetball racquet which have proven necessary for good playing characteristics for all such racquets have been maintained. The racquet (1) has synergistically combined the weight of the racquet, the stiffness of the frame (3), and the response characteristics to create a racquet of sufficient durability with a larger "sweet spot" to facilitate the palying of the sport and to increase the level of skill, particularly of the novice and intermediate players. The racquet (1) has an overall length of 18 ½ inches to 14 3f4 inches, a weight of 220 grams to 270 grams, and a center of gravity at a location within a range of ¾ inch toward the handle (3) and ½inch toward the head (2) as measured from the longitudinal center point of the racquet.</p>
