  • Patent number: 4247104
    Abstract: A racket, for use in playing tennis and similar games, includes a frame which defines a head and a handle, with the head having a generally polygonal configuration defined by a first pair of sides that extend from the handle away from each other to the widest portion of the head and a second pair of sides, connected to the first pair at the widest portion of the handle, extending back towards each other. The second pair of sides are longer in length than the first pair of sides and are connected by a fifth side which extends parallel to the widest portion of the head. Strings are strung between the sides of the head to define an impact surface which provides an enlarged "sweet" spot on the racket near the widest portion of the head as compared to conventionally shaped oval tennis rackets.
