ABSTRACT:
A tennis racquet which utilizes an energy input system is disclosed. The racquet head employs a flexible membrane which is held in place by membrane carriers secured to the interior of the head and to which the strings are attached. This membrane extends into the handle portion of the racquet where it is firmly anchored to a tensioning/energy input, storage and release device which in the preferred embodiment comprises a spring assembly. By adjusting this spring assembly, the player can dictate the amount of spring energy to be applied to an object striking the strings and thus determine the object's release speed and its dwell time on the racquet. Because the strings are not attached directly to the frame, the effective striking area of the racquet is enlarged.
