发明名称 Racket handle extension
摘要 Assisting a player of a racket sport, such as tennis, in positional awareness of the racket head, both visually and physically, is disclosed by adding an axial extension to the racket handle, the axial extension of similar or greater length than that of the racket. Regardless of racket position, whether or not within the direct sight of the player, a visually obvious indicator located at the end of the extension permits positional awareness of the racket before, during, and after each swing. Such positional awareness can also be obtained when both the racket and visually obvious indicator at the end of the handle extension are not visible by physical contact, when any part of the handle extension touches the body indicating poor racket initial position, swing motion, or follow-through after each swing.
