(2) Description of the Related Art

Tennis racket have become very popular in the last years for sport and exercises specially in young generation participation, at the same time and more particularly to improve the general tennis racket performances with new designs and improved strong lightweight Nano-Carbon fibers, by improving new construction techniques and technologies providing an extra-tennis strongest rackets with or without integral framing system, strings configuration, improvements made over the frame cross section design, all possible energy saving improvements by reducing vibrations and control torsional elasticity, and the most relevant and constantly improvement was made over the sweet-spot area and all combinations of above mentioned improvements.

This part of the patent description of the related art represents to a difficult challenge, that present invention related to a tennis racket that supports many mayor changes over the conventional tennis racket (in-Line-Symmetry) and “S” shaped last recently tennis racket design, to change the shape design, technically was re-shaped the geometry of the head-frame from conventional (in-Line-Symmetry) symmetrical oval egg-shaped designs to an original rounded-ellipse off-set head-frame design to form the technology I call “Triple-Axis-Symmetry”, creating a new head-frame figure which is geometrically asymmetrical measured from racket longitudinal-axis, which is different and advantageous in comparison with the classic tennis rackets design and “S” shape design. “Triple-Axis-Symmetry”, represents the most advanced improvement in any tennis racket ever build and design.

The other notorious differences between related arts and our present invention, is the three (3) independently head-frame mayor-axis connecting (lie) within the center head-frame system.

The racket asymmetrical throat design represents another huge difference between related arts and this present invention, the throat top portion straight-shafts interconnects within the head-frame lower loop portion mayor long and short axis and forms automatically the off-set head-frame rotation up to 45° angle.
