    • A sports racquet has a plurality of opposed string holes for anchoring the ends of the strings, at least one pair of contiguous string holes are replaced with an enlarged string hole having opposed bearing surfaces for securing the ends of a pair of contiguous string segments. Preferably, a plurality of contiguous enlarged string holes are employed along the sides, tip, and heel or throat bridge of the racquet, in order to reduce the weight of the racquet head. Also, preferably, the enlarged string holes are defined by a pair of opposed interior walls of the frame extending between the frame's inner and outer surfaces, thereby forming a truss-like internal structure for stiffening the frame. Moreover, the frame preferably has interior wall portions that extend between the string holes. Such wall portions lie in the string bed plane and underlie the string portions on the exterior of the frame.
    • 运动球拍具有多个用于锚定琴弦端部的相对的弦孔。 至少一对连续的串孔被具有相对的支承表面的扩大的串孔替换,以固定一对连续的串片段的端部。 优选地,沿着球拍的侧面,尖端以及脚后跟或桥接杆采用多个连续的扩大弦线孔以减轻球拍头的重量。 而且,优选地,扩大的细绳孔由在框架的内表面和外表面之间延伸的框架的一对相对的内壁限定,从而形成用于加强框架的桁架状内部结构。 而且,框架优选地具有在串孔之间延伸的内壁部分。 这样的壁部分位于弦床平面中并位于框架外部的弦部分之下。
