Abstract
Abstract A racket handle is provided which includes a handle member and a rod member forming a lower section of the racket frame. The handle member includes an outer pipe member and an inner pipe member defining a longitudinally extending closed annulus. The rod member is insertable within a bore formed by the inner pipe member and extends to a closed section or end of the inner pipe member. An elastic ring is mounted in the annulus between the inner and outer pipe member to absorb vibrational forces.
