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 has a head frame that includes a support member and an inwardly directed alignment member or fin. String segments are strung from a central strung area through respective holes in the fin, around the support member and back through further holes in the fin. The present invention provides a strong anchor for the strings which can withstand the static load thereof as well as dynamic loading placed on it by striking gamepieces as well as striking other objects. In a preferred embodiment, the fin returns the string segments to a strung area that is substantially planar up to the inner periphery of the fin.
