发明名称 SPELRACKET
摘要 This invention relates to a games racket, such as a tennis or squash racket, including a handle intended to be held in the hand, and carrying a head having an open marginal frame defining a central opening across which extends tensioned stringing carried by the head frame. Instead of being located in a single plane disposed centrally of and bounded by the head frame, the stringing of a racket embodying this invention is disposed in two generally parallel planes located on opposite sides of the frame, i.e. on opposite sides of the opposite side surfaces of the frame, and separated by a distance approximating the thickness of the frame. An elongate strip of a relatively hard synthetic plastics material extends around the central opening, and in a preferred embodiment, this strip overlies the outer peripheral surface of the frame and is provided with a plurality of stringing-receiving apertures distributed around the central opening, disposed outwardly of the outer peripheral surface, and spanning the opposite side surfaces of the frame.
