Inventions and inovations project

  1. 1. History of the Tennis Racquet
  2. 2. First Racquets <ul><li>By the 14 th century players began to use what we call tennis racquets. They were made with strings and a wooden frame. The Italians are often credited with the invention. </li></ul>
  3. 3. The Racquet is Patented <ul><li>In 1874 Major Walter C. Wingfield patented the racquet. At this time the size of the racquet head had increased </li></ul>
  4. 4. Wire Strung Racquets <ul><li>This racquet, with a metal head, never saw widespread use. 1889 </li></ul>
  5. 5. The Wilson T2000 <ul><li>Stronger and lighter than wood, it became a top seller. It had a long-throated, small-headed steel frame. 1967 </li></ul>
  6. 6. The Prince Classic <ul><li>They had aluminum frames and a string area more than 50 percent larger than the standard 65 square inch wood racquet. 1976 </li></ul>
  7. 7. Dunlop Max 200G <ul><li>The most famous of the early graphite racquets was the Dunlop Max 200G. Its weight in 1980 was 12.5 ounces. </li></ul>
  8. 8. <ul><li>In 1987 Wilson made a racquet with increased stiffness but without a stiffer material. The racquet was very big with a 39mm wide frame. </li></ul>Wilson Profile
  9. 9. Future Racquets <ul><li>Head has come out with a racquet that uses piezoelectric technology. Piezoelectric materials convert vibration or motion to and from electrical energy. Head's new racquet takes the vibration resulting from impact with the ball and converts it to electrical energy, which serves to dampen that vibration. A circuit board in the racquet's handle then amplifies that electrical energy and sends it back to the piezoelectric ceramic composites in the frame, causing those materials to stiffen. </li></ul>
