ABSTRACT:
A variable balance racket has a weight moveable from an inactive or rest position near the grip of the handle to an active position adjacent the head of the racket to increase the striking force of the head. The weight can be moved to the active position and held in this active position by a retainer, against the action of an elastic element which returns the weight to the rest position. The weight is released in response to the centrifugal force of the swing of the racket so it is automatically returned to the rest position before the next swing. This arrangement enables the player to move the weight to the active position prior to a serve or anticipated smash, while returning the weight to the rest position after such a swing for normal play or repositioning in the active position by the player.
