    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 extending around the greater part of the racket head, and integral with the wall a rigid section which is perforated at intervals to receive the stringing and which is formed as an elongate hollow protuberance projecting at least partially inwardly of the wall towards the center of the racket head. The main section of the frame is preferably a closed section, which may be internally divided into a plurality of discrete cells. The protuberant hollow section may be substantially circular in cross-section or generally rectangular in cross-section for example.

    摘要: A racket frame comprises a thin, elongated tubular metal member 12 of hollow oval cross-section bent to form a head portion and a handle portion. The elongated tubular member is filled with a rigid foamed core 15 therein, thereby reducing the weight of the frame as well as vibration induced upon stroke.

    摘要: There is disclosed a method of making a game racket frame which comprises the use of a tubular body of aluminium alloy consistent with a shape of a racket frame (10). An annular recess (20) is provided respectively at the mid-point of the left-hand half of the head frame (121) and at the mid-point of the right-hand half of the head frame. The annular recess (20) is coated with adhesive resin. The tubular body is placed in a moulding tool (30) comprising a mould cavity (34) having an annular ring which is located at a position corresponding to the annular recess (20) of the tubular body and which has a shape corresponding to that of the annular recess (20) of the tubular body and a size slightly larger than that of the annular recess (20) of the tubular body. Molten plastics material is injected into the mould cavity (34) under pressure and heat. Upon completion of the curing of the plastic material, the racket frame is removed from the moulding tool. The racket frame so made is provided with weight-balancing pieces (16, 18) fastened securely to the head frame (12) of the racket (10).
