Throatless squash racquet
摘要:
A throatless squash racquet includes a hollow tubular frame, preferably of graphite, bent to form a head in which the outer portion is generally circular. The opposing legs of the tubular frame curve inwardly toward one another and then converge linearly. The converging legs continue to converge, but in an inverse curve, to define a narrow neck region, and merge into an elongated shaft. Because of its geometry, the racquet exhibits improved strength and durability.
