Abstract

Sports rackets having strings 19 supported by tension transmitting devices 27 positioned between the string sections or chords and an outward facing head frame 17 surface. Tension is transmitted between connecting string sections by the tension transmitting devices. Such transmission of tension allows strain energy to be stored in additional string sections instead of only those directly contacted by a ball or other impacting object. One form of the tension transmitting device is an independent rocker member that receives and supports the string as it wraps over the outer surface of the racket head.
