  • Patent number: 4470599
    Abstract: A grip for a racket for tennis and other similar games which includes relatively flat faces on one side for engagement with the thumb and fingers and a rounded or elliptical face disposed on the opposite side of the grip from the flat faces for engagement with the palm of the hand. Corners at the intersection of the flat faces provide control of the racket while the rounded portion nestles in the palm for a comfortable and secure gripping of the racket to prevent rotation thereof. The same grip may be used either for a forehand or backhand position and either for a left handed or right handed person, merely by inversion of the racket.
