Abstract (en)
[origin: EP0337326A2] In the handle for a racket for ball games, the grip body is surrounded by a grip sleeve and a ventilation chamber is constructed between the grip sleeve and the grip body. For the purposes of essential damping of oscillations and vibrations at the moment of impact of the ball, provision is made for the volume of the ventilation chamber to be variable by the compression forces exerted by the hand of the respective player during the game and for at least some of the openings provided in the grip sleeve to form a suction or ejection opening for the air flow caused by the volume variations. <IMAGE>
