Abstract:

A bumper strip surrounding the upper peripheral portion of a racket and for providing protection against injury to another player and to painted surfaces of a playing court is structurally integrated with the racket frame by passing string with which the racket is strung through the holes formed in the bumper strip whereby upon the string being tightened, the bumper strip is forced into engagement with the racket frame and whereby upon the bumper strip being removed the racket is rendered inoperable for play; and/or, a throatpiece is structurally integrated with the racket frame by passing the string through holes formed in the throatpiece which string upon being tightened in cooperation with projections extending outwardly from the sides of the throatpiece and extending into holes formed in the racket frame structurally integrates the throatpiece and the frame. The projections formed on the side of the throatpiece and the frame holes within which they are received permit limited flexing rotation between the throatpiece and the frame which accommodates the torsional rotation experienced by the frame in the throatpiece area upon a ball impacting the racket.
