Abstract
A tennis racket comprising an annular head and a shaft forming the handle, the head being spanned by stringing, has a pair of profiled members one of which is open-ended and forms the external periphery of the head and the sides of the shaft, the other profiled member being closed into a loop and forming the internal periphery of the head. The mutually opposite faces of the racket are constituted by two substantially flat parallel elements which form, together with the profiled members, a tubular structure whose interior is filled with a synthetic resin cast in situ. The confronting surfaces of the two profiled members are formed with grooves in which reduced edge portions of the flat elements are received to define the space filled with the synthetic resin.
