<p>A racket frame comprising a head, a shaft, a bifurcated throat and a connecting yoke 17 across the throat is equipped with a vibration-damping mounting for the stretched strings S. The mounting comprises a viscoelastic member 20 placed where the vertical strings are longest, on the outside of either the yoke 17 and/or the crown of the head, and preventing direct contact of the frame with a curved plate member 30; the strings S pass through opening(s) in the frame and the elastic member 20 and are wound round the plate 30 via string holes 32. The openings 17a and 21 may each receive a plurality of strings so that the degree of freedom of movement of the strings S is increased for better rebound performance. A twin-yoke embodiment, Fig 9A (not shown) may have a through hole for strings in the upper yoke, and the vibration-damping mounting on the outside of the lower yoke, nearer to the handle and grip.</p> |
