ABSTRACT OF THE DISCLOSURE A ball racket, in particular a tennis racket includes a closed inner frame with a stringing 3 and an outer frame with handle 2 which at least partly encloses the inner frame. The frames 1, 4 are connected at various points by at least two joints such that a local rotation of both frames relative to each other is permitted at the points of connection. The joints 5 are arranged relative to each other in such a manner that the inner stringed frame 4 is prevented from carrying out a rigid-body motion relative to the outer support frame and that both frames 1, 4 are prevented from carrying out a translational movement relative to each other in a perpendicular direction to the racket plane of the frames.
