US Patent 7252607 Anchor fitting for a hollow ball

An anchor fitting for a hollow ball includes a pair of shoulder defining bodies and an anchor body. These are located within the ball, the anchor body holding the shoulder defining bodies in place with respect to the ball so that with the anchor body having a cord, a tail, or a stem for a tail anchored thereto, the shoulder defining bodies will be effective for retaining the anchor fitting within the ball while playing a game which involves the ball being struck with a bat or racquet. The parts of the fitting are separately displaced through a hole in the wall of a ball, the anchor body permitting cooperation with an elongate element for facilitating the effective assembly of the fitting.
