ABSTRACT:
The invention relates to a frame for a games racket e.g. tennis, of the type made as a hollow injection moulding of reinforced thermoplastics material. The frame has attachments for stringing in the form of a series of discrete lugs moulded integrally with the walls of the hollow frame and so positioned that the racket strings in their desired positions do not pass to the outer periphery of the head. The discrete lugs may for example be around the inner periphery of the head of the frame and each contain an integrally-moulded circumferential bore for string passage. The frame may be made by injection moulding around a fusible core and the shape of the core required to give the desired lugs provides strong resistance to movement under the injecting pressures hence giving improved product uniformity.
