    摘要: A racket, especially for tennis and squash, has a strung head portion defined by a rigid frame of novel cross-sectional configuration. The frame has an imperforate wall (24) extending around the greater part of the racket head, and integral with the wall a rigid section (20) which is perforated at intervals to receive the stringing and which is formed as an elongate hollow protuberance (32) projecting at least partially inwardly of the wall (24) towards the centre of the racket head. The main section (18) of the frame is preferably a closed section, which may be internally divided (30) into a plurality of discrete cells. The protuberant hollow section (20) may be substantially circular in cross-section or generally rectangular in cross-section for example.
