ABSTRACT:
A tennis racket which exhibits, through a novel combination of critical material characteristics (composition, treatment, weight distribution and, particularly, the dimensions of width and thickness of various interrelated frame elements) optimum strength, playability, weight, stability and freedom from deleterious vibration during use. The racket frame is a one-piece forged metal (preferably aluminum) unit having a thickness throughout the head and shaft in the range of 0.580-0.600 inches. The width dimension of the head portion remote from the handle is critically determined at 0.280 .+-. 0.020 inches. The width of the side portions of the head is critically determined at 0.230 .+-. 0.020 inches. The width dimension for the portion of the head adjacent the handle is critically determined at 0.200 .+-. 0.020 inches. Between the respective adjacent portions of the head, the width dimension tapers gradually between the dimensions specified.
