| 摘要 |
The present invention relates to a tensioning device for dampening vibrations generated in a striking surface of a sporting racquet. The tensioning device has a tubular body portion having cylindrical outer and inner walls and two end surfaces. The cylindrical outer wall has a diameter substantially equal to a spacing formed by two generally parallel strings of the sporting racquet. A dampening unit is disposed inside the tubular body portion. The dampening unit has a center post substantially concentric with the tubular body portion and plural leaf members connecting the center post to the inner wall of the tubular body portion. The tensioning device also has two sets of flange members extending radially outwardly from the outer wall of the tubular body portion and near the end surfaces respectively. The two sets of flange members define a peripheral channel portion therebetween to accommodate strings of the sporting racquet whereby the tensioning device is retained in place.
