ABSTRACT:
A sports racket has a handle and a multi-frame. The multi-frame includes a primary frame defining a throat connected to the handle and a hoop-shaped head connected to the throat and encompassing an open region. The head has a plurality of stringing holes defined therethrough for attaching stringing to the head and across the open region. The multi-frame also includes supplementary frames and ribs. The supplementary frames are disposed in spaced relation and adjacent to opposite sides of the primary frame. The supplementary frames are coextensive with all or a portion of the primary frame head, plus all or a portion of the primary frame throat. The ribs are spaced from one another and extend between and rigidly interconnect the supplementary frames with coextensive portions of the primary frame. The ribs and supplementary frames serve to increase the stiffness of the primary frame, reducing axial and torsional deflections thereof upon striking a ball by the stringing across the open region of the head. The multi-frame further includes supplementary bracing interconnecting portions of the supplementary frames alone or with the primary frame in the region of the throat thereof.
