摘要 |
<p>A device (12) for dampening vibrations in a sports racket includes an elongated elastic hollow tubular member (28) and inelastic end members (30) on the opposite ends (28A) for securing the tubular member in a stretched condition to the string grid. The hollow tubular member (28) encapsulates a viscoelastic energy damping medium (44) and the inelastic end members (30) have a stem portion (34) for frictional engagement with the elastic tubular member and outer hook shaped elements (30B) for anchoring the device to the strings.</p> |
