    摘要： A racket frame structure includes a main body having an inner side wall and an outer side wall. The inner side wall of the main body having two sides each formed with a plurality of reinforcement ribs. The reinforcement ribs are located at connections of the main strings and the cross strings on the main body. Thus, the main body at the connections of the main strings and the cross strings is strengthened by the reinforcement ribs so as to enhance the strength of the main body, thereby preventing the main body of the frame from being deformed, distorted or broken at the connections of the main strings and the cross strings due to a larger striking force.

    摘要： A badminton racket is composed of an oval frame, a grip, and a shaft fastened between the oval frame and the grip. The shaft has a shell which is formed of a plurality of fiber-reinforced plastic layers and at least one metal gauze layer. The metal gauze layer is formed of a first metal filament and a second metal filament such that the first metal filament is extended in a direction forming an angle with the longitudinal axis of the shaft, and that the second metal filament is extended in a direction forming an angle with the longitudinal axis of the shaft. The angles so formed are preferably 60 degrees each.

    摘要： A racquetball racquet having a metal frame is disclosed, wherein increased stiffness in the metal frame is provided by a grooved contact between the inner surfaces of the frame comprising the outer perimeter of the racquet and a throat piece, completing the reinforced enclosure within which the strings are arranged. This grooved contact of the throat piece with the metal frame further resists the stress and strain of contact between the racquet and the racquetball, such that the entire surface of the strings behaves in a uniform and predictable fashion.

    摘要： A game racket has a metal frame, elastomeric yoke, and preformed handle. The frame cross-section employs opposite tubular elements joined by a central web, with the tubular walls facing oppositely from the web being formed in an arch having a common radius at the midpoint of the web. The yoke employs torque box construction and has an integral metal arch anchoring the yoke to the racket frame, and the yoke has laterally extending lips that engage the surfaces of the frame to damp vibration from the racket face. The handle employs a sleeve overlapping divergent portions of the metal frame and a central plug that fits between the divergent frame portions to hold them in spaced relationship, or alternatively the handle employs front and rear caps having an intermediate foamed plastic or elastomer body.

    摘要： A game racket having a string net, the tension of the strings in the net being easily adjustable. The racket has a handle, a hoop attached to the handle, and strings forming a net across the hoop. A wedge located in the hoop and having longitudinal central strings attached thereto, the wedge being drawn by a threaded rod toward the handle to cause an increase in the peripheral dimension of the hoop and thereby a tightening of the strings and an equalization of tension throughout the net.

    摘要： 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.
