ABSTRACT:
A racket frame, such as for a tennis racket, has a head portion, a handle portion and a throat portion extending between and interconnecting the head and handle portions. The head portion encompasses an open region and has a plurality of stringing holes for attaching stringing to the head portion and across the open region. The throat portion is in the form of a pair of legs in a generally V-shaped configuration. Different cross-sectional dimensional relationships are incorporated in the racket frame to tailor racket frame stiffness. A first cross-sectional dimensional relationship relates to location of the maximum cross-sectional height of the racket frame in a lower extent of the head portion thereof so as to define a dual reverse tapered profile along the cross-sectional height of the racket frame. A second cross-sectional dimensional relationship relates to provision of an abrupt transition in an inwardly facing surfaces of the head portion of the racket frame so as to define a dual tapered profile along the cross-sectional width of the racket frame head portion. A third cross-sectional dimensional relationship relates to variation of cross-sectional height to width along the throat portion of the racket frame so as to define greater throat portion height nearer to the head portion and greater throat portion width nearer to the handle portion.
