<p>To change the centre of gravity of a ball-striking implement, in particular a tennis or squash racket, two or more continuous cords (14', 14") are arranged running round in the interior of the frame (12) of the ball-striking implement, which cords can be actuated from the outside and to which a weight (10', 10") is attached in each case. By moving the cords (14', 14"), the weights (10', 10") can be moved slightly in the same direction in the longitudinal direction of the frame and the centre of gravity of the implement can thus be changed. <IMAGE></p> |
