ABSTRACT:
Improved tennis racket in which an inverted chevron shaped yoke is provided having downward sloping side portions which match the curvature of the arcuate top portion of the racket head to provide vertical strings extending between the yoke and arcuate top portion which are of the same length. The equal length of vertical strings provide uniform elastic response to ball impact. The particular design of the chevron provides added structural strength to the neck of the racket. An improved racket made from a polycrystalline metal oxide fiber and resin matrix is also disclosed. In addition, an improved string protection system involving elastomer inserts which are molded into the head portion of composite material rackets is described.
