Abstract
The present invention is directed to a racquet design with an inner and outer frame connected by an isolation system. Uniquely adapted to tennis racquets, the natural motion of the inner frame relative to the outer frame upon impact of the tennis ball on the inner frame will generate spin when the ball contacts the inner frame. The relationship between the inner frame, outer frame and isolation system can control the spin imparted to the ball for a given tennis swing. The tuning of the isolators relative to conventional racquet characteristics will increase the amount of ball spin caused by conventional racquets. The invention also increases the accuracy of the tennis ball's trajectory.
Claims22
A racquet with a frame isolator comprising:
- a handle having an outer frame attached to said handle;
- an inner frame having a string bed formed from a plurality of cross string elements and a plurality of main string elements;
- and a plurality of isolators securing said inner frame to said outer frame, said isolators constructed and arranged to adjust in-plane and out-of-plane stiffness between said inner and outer frame.
A tennis racquet with a frame isolator comprising:
- a handle having an outer frame attached to said handle;
- an inner frame having a string bed formed from a plurality of cross string elements and a plurality of main string elements;
- and an isolator means securing said inner frame to said outer frame, said isolator means constructed and arranged to adjust in-plane and out-of-plane stiffness between said inner and outer frame wherein said inner frame moves in-plane relative to said outer plane to generate spin and provide spin control to a tennis ball impacting said string bed.
