Abstract
The improved racquet has a strung surface which is larger in area than the strung surface of a conventional racquet, and in which the strung area is both longer 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 has synergistically combined the weight of the racquet, the center of mass of the racquet, the stiffness of the frame, and the response characteristics to create a racquet of sufficient durability with a larger "sweet spot" to facilitate the playing of the sport and to increase the level of skill, particularly of the novice and intermediate players. The racquet has an overall length of .[.181/2.]. .Iadd.19 .Iaddend.inches to 221/2 inches and a width of 91/2 inches to 111/2 inches, a weight of 220 grams to 270 grams, and a center of gravity at a location within a range of 3/4 inch toward the handle and 1/2 inch toward the head as measured from the longitudinal center point of the racquet.
