发明名称 UNA RAQUETA QUE TIENE PROPIEDADES MEJORADAS EN EL IMPACTO DELA PELOTA.
摘要 <p>A tenis or squash racket wherein, by changing the number of strings in the racket and rearranging their location, the shock of the impact of the ball upon the racket is resiliently absorbed over a longer period of time than heretofore and a better control of the ball is obtained. A centre group of vertical strings is provided, wherein the strings are closely spaced about the centre of the racket and two strigs are positioned on either side of the centre group which are further apart in the remaining racket space. There is a horizontal string group closely spaced principally about the centre with a fewer number of strings on either side between the horizontal string group and the top and the bottom of the racket.</p>
