Abstract

Abstract An attachment for the handles of rackets or paddles used for tennis, paddleball, and the like sports and games provides an abutment enabling the user to exert pressure and power to eliminate slippage and deliver more power to the ball or the like struck by the racket or paddle. The abutment is preferably part of the grip portion of the handle of a racket or paddle in the form of an outturned concave peripheral rib at the inner end of the grip to be engaged by portions of the hand of the user in a manner which does not confine or alter the user's grip but receives thrust from the user to deliver extra power and eliminate slippage. The rib is an extension of the faces of the grip and is preferably the base of a flat faced cone converging to the paddle or racket handle. The forefinger of the user's hand fits comfortably against the rib preventing the hand from slipping up on the handle and also exerting driving force from this forefinger to the racket or paddle. The tip end of the thumb may also be pressed against the rib and since the rib provides added thickness to the handle the thumb and forefinger will not be pinched together thereby minimizing rotation of the handle to keep the racket head square at impact. The device does not interfere with rotating or spinning of the racket or paddle between strokes and since the rib circumscribes the grip it will function in the same manner when using either striking face of the racket or paddle. The device is somewhat resilient to absorb vibration and shock.
