  • Patent number: 5316296
    Abstract: An energy-absorbing game racket designed as a pair of planar surfaces extending from a handle constructed as a sandwich design within a frame, with a set of coil springs compressed within the space defined between opposing surfaces. One of the surfaces is mounted to move within the frame against the springs such that it has a springy characteristic, while the other surface is stiff. In a racket ball game volley, either surface may be directed so that the ball impacts it. When the springy surface is directed toward the ball, it partially absorbs the impact force thereof, while the stiff surface does not. This design enhances the player's ball control options in delivering the return volley. An additional feature of the inventive game racket is the provision of an audio indication associated with impact of the ball on a particular area of the racket surface. A lamp and counter may also be provided for this purpose.
