Abstract: Tennis racquet comprises a tennis racquet throat “Triple-Asymmetrical-Yokes system showing the innovative geometric properties and detailing the most relevant angles and lineal general measurements, A tennis racquet throat “Triple-asymmetrical-Yokes” system, comprising: an racquet throat supporting three-asymmetrical-yokes all measured from racquet main-shaft-handle-longitudinal-axis, main-yoke support two-asymmetrical-stretch-shafts diagonally-aligned, and interconnects with right-yoke-left-straight-shaft and left-yoke-right-straight-shaft, main-yoke-lower-square-shaft interconnects with top-octagonal-symmetrical main-handle-shaft, right-yoke support two-asymmetrical-shafts, left-straight-shaft which interconnects to main-yoke-right-stretch-shaft, right-yoke-curved-shaft which form part of the lower-portion-head-frame-loop, left-yoke support two-asymmetrical-shafts, said left-straight-shaft which interconnects to main-yoke-left-stretch-shaft, left-curved-shaft which form part of the lower-portion of head-fra

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.

Abstract: A skateboard in accordance with this present invention includes a aerodynamic deck design and the aerodynamic board supporting at least four interchangeable independent chassis supporting at least four removable integral multiple action independent suspension truck-free system, the suspension system support at least four and eight-wheeled configurations having all forks axles pivotally in forward motion and opposite direction from each other. The integral independent suspension system all parts and components are integrated in a body-frame, includes at least two independent shock-absorber mechanisms in whish the front shock-absorber suspension mechanisms interconnects with the rear shock-absorber secondary mechanisms, in which the rear shock-absorber mechanisms support the pivotally axles and wheel system.

Abstract: Tennis Racket comprises an elliptical head frame and framing system design angularly mounted, triple independent strings and strings channels, variable center of gravity, main frame handle body-frame damper systems:

Abstract: An in-line roller skate in accordance with this present invention includes at least four integral independent suspension system aligned under the chassis platform having all forks axles pivotally in forward motion and opposite direction from each other. The integral independent suspension system all parts and components are integrated in a body-frame, includes at least two independent shock absorber mechanisms in which the front shock absorber suspension mechanisms interconnects with the rear shock absorber secondary mechanisms, in which the rear shock absorber mechanisms support the pivotally forks axles and wheel system. The main chassis system supports the front brake and central rolling-brake. The integral independent suspension and the removable boot systems are interconnected with the chassis system trough a plurality of removable fasteners. The removable boot supports the front and rear anatomical-frame structure and the rear integral independent suspension support the main brake system.
