ABSTRACT:
A tennis racquet comprising a frame providing an open, tensioned string receiving, playing head of generally elliptical contour, and an elongated handle extending from one end of the head and terminating in a hand grip, the contour of the open head at the hand grip end thereof being closed at a point between the center of gravity and the hand grip end of said racquet. A preferred form of the racquet comprises a unitary frame bowed in its central portion to form a generally elliptical head contour and continuing as coplanar throat and shaft extensions which are joined at their extremeties in a hand grip, and the first joining of the ends being at a point between the center of gravity and the hand grip end of the racquet. Central longitudinal strings may join the frame at points closer to the hand grip end than is the center of gravity, and the longitudinal strings are under somewhat greater tension than the transverse strings. The racquet is characterized by reduced weight in the throat portion, resulting in the percussion center of the stringed area being significantly advanced toward the tip end of the racquet, and the vibration level being reduced.
