  • Patent number: 4088320
    Abstract: An attachment for a tennis racket characterized by a pair of resilient retaining members releasably positioned on the frame of the racket and arranged to receive a tennis ball resting on a court or other surface, and to raise such with upward movement of the racket for subsequent removal and use. With the ready grasping of a tennis ball, the tennis racket attachment eliminates, or at least minimizes, the countless bending and stooping formerly required for tennis ball retrieval during the course of a tennis game.
