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.
A games racket comprising 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, the stringing being composed of a first group of generally parallel string portions, and a second group of generally parallel string portions extending generally perpendicular to, and interwoven with, the string portions of the first group, the thickness of the frame in a direction generally normal to the plane of the stringing being substantially greater than the thickness of the stringing, the frame including a structural marginal frame part defining the central opening, and a separate flexible but substantially incompressible, elongate member having an upper portion and a lower portion and formed from a relatively hard synthetic plastics material, extending substantially continuously, at least from one side of the handle, around the outer peripheral surface of said frame part to the other side of the handle, and overlying said outer peripheral surface, said frame part and said lower portion of the elongate member having at least one interfitting projection and recess, said elongate member being formed with a plurality of stringing-receiving apertures distributed around a major proportion of the peripheral extent of the frame, said apertures being spaced from the outer periphery of said upper portion of the elongate member, and extending continuously between and opening into, opposite side surfaces of said elongate member which are spaced apart in said direction, said elongate member, in the zones thereof provided with said apertures, having a thickness in said direction approximating the thickness of said frame part, and at least the outer peripheral surface of said upper portion of the elongate member, over substantially its entire length, being relatively smooth, uninterrupted, and devoid of projections, said tensioned stringing carried by the head passing through said apertures, and being disposed in two generally parallel planes separated by a distance approximating the thickness of the frame in said direction.
