发明名称 Tactile training device for a tennis racket handle
摘要 An attachment to the handle of a racket which tactically indicates to a player whether his/her hand has properly gripped the handle of a racket for forehand and backhand play. The attachment is an elongated member non-rotatably connected to the butt of the handle and positioned substantially parallel to the face of the racket such that it bears evenly against the heel of a player's hand when he/she properly grips the handle. The elongated member further includes a contoured recess configured to comfortably receive the outer edge of a player's hand when the hand has been rotated substantially ninety degrees from the forehand to the backhand play positions.
