    摘要: A tennis racket of oval overall shape is characterized in that the face comprises five regions. The geometric centre (M), the hilting centre (P) and three transverse strings are located in a central region (A), and three transverse strings the mean length of which is greater than that of the region (A) are located in each of two regions (B and C). The area in which the elasticity is substantially unifrom is thereby increased.

    摘要: 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 3 f 4 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.

    摘要: A racquet includes polyester, monofilament racquet string and a frame extending along a longitudinal axis and including a head portion coupled to a handle portion. The head portion includes a hoop having inner and outer peripheral walls. The hoop defines a head size having maximum longitudinal and transverse dimensions, a , and, b , respectively. The dimension a is at least 1.2 times the dimension b . The inner peripheral wall includes string holes. The string has a diameter within the range of 1.10 to 1.55 millimeters. The string forms a string bed of interlaced main and cross string segments. Each of the cross segments transversely extends from one of the string holes to another, and each of the main segments longitudinally extends from one of the string holes to another. The string bed has at least one more main segment than cross segment, At least one of the main segments contacting the tennis ball exhibits a snap back velocity of at least 1 meter per second.

    摘要: Bei einem Ballschäger, insbesondere Tennischläger (2) mit einem Schlägerkopf und einem Griffteil (3), wobei die Rahmenholme (1) sich vom Griffteil (3) über den bespannten Bereich des Kopfteiles erstrecken, bei welchem die offene Fläche zwischen den spitzwinkelig in den Griffteil mündenden Rahmenholmen (1) zur Gänze die Bespannungsebene bildet und die in Schlägerlängsachse verlaufende längste mittlere Saite (4) zwischen dem Kopf und dem den Griff benachbarten Ursprung des spitzen Winkels (α) der in den Griffteil (3) mündenden Rahmenholme (1) gespannt ist, weist der Schläger (2) ein bespanntes Gewicht von weniger als 260 g und eine Frei-Frei Eigenschwingungsfrequenz von größer 200 Hz auf. Das Verhältnis der Breite der bespannten Fläche zur Länge der längsten Saite der bespannten Fläche ist kleiner 0,6.
