摘要： A sports racket, for tennis and the like sports, has an elongated handle attached to a head having a racket face, which is spanned by a uniform string structure. The head has four sides, forming a non-elliptical shape, in which the opposite sides are substantially parallel. Longitudinal strings, all of which are substantially identical in length and run essentially parallel to each other, and transversal strings, all of which are substantially identical in length and run essentially parallel to each other and perpendicular to the longitudinal axis, span the racket face. The racket has a larger racket face than conventional rackets, while maintaining the length and weight measurements of conventional rackets, resulting in a very large sweet spot and more good hits. The racket has maximally long strings at all points on the racket face and strings substantially identical in length at all points on the racket face resulting in a uniformity of response for off-center hits, an increase in the ball rebound speed, a decrease in angular deflection for off-center hits, and the ability to set the tension of the strings such that they vibrate with the same frequency. The racket has a greater moment of inertia than conventional rackets, resulting in reduced racket rotation and a reduction of injuries to players, such as nulltennis elbownull.

摘要： This invention provides for a racquetball racquet combining enhanced ball acceleration, high precision, and comfort. These optimum characteristics are achieved though a racquetball racquet having, in combination, an overall length of between 500 mm and 580 mm, an unstrung weight of between 140 g and 195 g, a head weight of between 52% and 65% of the overall racquet weight, and a center of gravity located between 25 mm relative to the racquet head handle end and 75 mm relative to the distal head end, measured along the longitudinal axis of the racket. The longitudinal strings of the racquetball racquet extend from the racquet head handle end to the racket head distal end are arranged so as to diverge to form a V-configuration. Two neighboring longitudinal strings are each led to a common location on the racquet head handle end.

摘要： Provided herein are racquets, such as sports racquets. The racquets generally comprise a head frame with a curved side rim and substantially parallel straight top and bottom rims and handle affixed to the head frame between the top rim and rims. A plurality of openings are equally spaced through the head frame and a portion of the handle and a plurality of strings comprising a net pass through the openings. The length of the top rim of the head frame is greater than the bottom rim. The handle connects to the head frame at an angle of about 140° to 150°.
