Abstract

Tennis racket comprises a rounded-elliptical off-set head frame design, three (3) independents mayor-axis connecting within the racket head-center, head-frame long-axis support parallel long strings setup, head-frame short-axis support parallel short strings setup, head-frame longitudinal-axis support diagonals strings setup and diamond shape configurations. A tennis racket in accordance with this present invention which include an asymmetrical throat portion and connects with an symmetrical straight handle system, the asymmetrical throat top portion connected to the lower portion off-set head-frame, in which the straight left-throat-shaft connects with the head-frame longitudinal-axis and the straight right-throat-shaft connects with the head-frame short-axis, in which the lower portion of the throat (yoke) interconnects with the square top portion of the handle shaft system. With the principal objective is to improving the overall playing characteristic from conventional tennis rackets (in-line-symmetry) to a full ergonomic concept in all ways.
