    • Tennis rackets having a primarily rectangular shape comprise a frame and string arrangement that creates a tennis racket with the advantages of a rectangular racket without the structure and weight of a purely rectangular racket. An embodiment has an outer frame (20) with generally straight portions (25a, 25b) at a top and bottom of the outer frame. Lateral strings connected to these generally straight portions have generally the same length. A separate distal lateral member (26.1) of the frame provides a connection component for longitudinal strings having generally the same length. The tennis racket having a primarily rectangular shape with separate distal lateral member creates a sweet spot that is much larger than conventional oval-shaped rackets, but is lighter and structurally stronger than rectangular rackets lacking these features.
    • 具有主要矩形形状的网球拍包括框架和绳子装置,其产生具有矩形球拍的优点的网球拍,而没有纯矩形球拍的结构和重量。 一个实施例具有在外框架的顶部和底部具有大致直的部分(25a,25b)的外框架(20)。 连接到这些大致直的部分的横向串通常具有相同的长度。 框架的单独的远侧横向构件(26.1)提供了用于具有大致相同长度的纵向连杆的连接部件。 具有主要矩形形状的网球拍具有单独的远侧横向构件,产生比常规椭圆形球拍大得多的甜点,但是比缺少这些特征的矩形球拍更轻且结构更坚固。
