摘要： This relates to a game racket, such as a tennis racket, wherein the hand grip portion of the handle is both offset from the general plane of the head and also disposed at an angle thereto. The handle is so configurated with respect to the head wherein the center of gravity is along the axis of the hand grip portion to provide for a balanced condition. This arrangement of the handle with respect to the head permits a greater moment of inertia, by which a greater stability is obtained, particularly one against twisting of the racket in one's hand when the ball is struck off-center of the head; that is, on either side of the longitudinal axis of the racket head. Further, by off-setting the handle, a greater arc of stroke is possible, thereby permitting a struck ball to be repelled with a higher velocity.

摘要： This relates to game rackets, such as tennis rackets, and to paddles, such as table tennis paddles, with two discrete playing surfaces wherein the planes of the playing surfaces intersect each other generally at the crown portion of the racket head or paddle blade. This relationship of the playing surfaces permits a greater arc of stroke by a player thereby permitting a struck ball to be propelled with a greater velocity. It also permits a player to strike a ball in a more forward position thereby making it easier for the player to "keep his eye on the ball," with a resulting better ball control.
