  • Patent number: 5263712
    Abstract: A game racket comprises a head with a stringed surface and a shaft connected with the head and provided with a handle. The shaft further has a throat piece adjacent to a yoke of the head. The throat piece is provided with two arms arranged in a V-shaped fashion. Located between the throat piece and the handle is a connecting portion, which comprises a through hole traversing the short axis of the shaft and parallel to the direction of the stringed surface. Similarly, each of the two arms of the throat piece is provided with a through hole. Each of the through holes is provided with an elastic shock-absorbing body inserted thereinto. The stringed surface is composed of a plurality of long strings, which are fastened to the elastic shock-absorbing bodies. As a result, the shock energy generated by the stringed surface upon hitting a ball is effectively absorbed and attenuated by the elastic shock-absorbing bodies.
