摘要： A string and handled racquet (20) has at least a portion of the strung length of at least some of its strings (24) within a cavity (28) defined by the racquet's handle (26) or handle/shaft combination (118/120). The cavity (28) may be nearly as long as is the handle (or handle/shaft) itself. The "long" strings (34) are connected to one or more connection points within the cavity (28), which are displaced from the cavity opening by at least one-half the length of the handle or handle/shaft combination. The "long" strings are disposed in free space or with only minor obstruction within the cavity. The "long" strings are subject to being displaced a greater distance from the plane of the racquet during ball strikes and strokes than are the shorter strings for which they substitute, beneficially permitting a greater energy storage in the strings and racquet frame, a larger sweet spot, longer ball contact, and a more prolonged and greater return of energy to the struck ball.

摘要： A sports racquet frame is built of a composite of laminations of fibrous material as impregnated by a thermosetting resin. The head section of the frame has an upper tube preferably disposed above the string bed plane and a lower tube preferably disposed below the string bed plane. A solid bridge of material integrally joins the upper tube to the lower tube. In a preferred embodiment the bridge is disposed radially exteriorly of the center line of the tubes, to maximize the length of string segments, which are strung to the bridge.
