发明名称 String tension transmitting apparatus
摘要 A string tension transmitting device positionable against an outwardly facing head frame surface of a stringed sports racket. The tension transmitting devices receive and support the racket string thereover. The devices are adapted to the head frame surface to form a rocking relation therewith. Relatively greater tension in one string chord can be transmitted through the tension transmitting device to an associated string chord. Such transmission of tension allows strain energy to be stored in several string chords in addition to chords directly contacted by the ball or other impacting object. This results in a larger overall deflection of the string face of the racket and a lower peak dynamic string tension. The tension transmitting device includes rocker members that can be received between the string and racket head as it wraps over the outer racket head surface. The rockers receive the string along string receiving surfaces such as grooves formed in top surfaces of the rocker members. Opposite the string receiving surfaces are rocker surfaces that provide for relatively friction-free rocking engagement against the outer surface of the racket head frame. Also disclosed are rackets adapted with the string tension transmitting devices.
