    Abstract: A handle for a racket of the type used in playing tennis and like sports includes an elongated shaft portion, a hollow grip portion attached to one end of the shaft portion and a frame portion connected to the other end of the shaft portion. The shaft portion includes two spaced apart hollow tube sections which, in their surfaces facing toward each other, are provided with slots extending in the longitudinal direction of the tube sections. The space between the portions of the tube sections which face each other in the transverse direction of the tube sections forms a Venturi region for creating a zone of reduced air pressure between the tube sections when the racket is swung during play. The zone of reduced air pressure cases air to be drawn from the interior of the tube sections through the longitudinal slots. The air drawn through the longitudinal slots is conducted from the tube sections and a passageway formed in the grip portion and through openings provided between the passageway and the periphery of the grip portion. The air flow generated when the racket is swung serves to ventilate the hand and to remove perspiration accumulating during play.

    Abstract translation: 用于打网球和类似运动的类型的球拍的手柄包括细长轴部分，附接到轴部分一端的中空抓握部分和连接到轴部分另一端的框架部分。 轴部包括两个间隔开的中空管部分，它们在它们彼此面对的表面中设置有在管部分的纵向方向上延伸的槽。 在管部分的横向方向上彼此面对的管部分之间的空间形成文丘里区域，用于当球拍在游戏期间摆动时，在管部分之间产生减小的空气压力区域。 减小空气压力的区域表示从管部分的内部通过纵向狭槽抽出的空气。 通过纵向狭槽抽出的空气从管部分和形成在把手部分中的通道传导通过设置在通道和把手部分的周边之间的开口。 当球拍摆动时产生的气流用于使手通风，并消除在播放期间积聚的汗水。

    Abstract: A racquet for use in racquet sports is disclosed. In the preferred and illustrated embodiment, a composite racquet construction is set forth which utilizes an extruded metal frame which accepts multilayered, laminated, fiber reinforced, resin material typically including an epoxy base with graphite or fiberglass therein. The extruded section receives the laminate material prior to curing wherein the metal extruded section serves as a mold. After curing, the composite frame has improved properties over the metal extrusion, alone, and enhances frame strength, rigidity and flexure characteristics. The extruded frame incorporates a central webbing which is subsequently drilled with holes for stringing the racquet.

    Abstract: A bumper strip surrounding the upper peripheral portion of a racket and for providing protection against injury to another player and to painted surfaces of a playing court is structurally integrated with the racket frame by passing string with which the racket is strung through the holes formed in the bumper strip whereby upon the string being tightened, the bumper strip is forced into engagement with the racket frame and whereby upon the bumper strip being removed the racket is rendered inoperable for play; and/or, a throatpiece is structurally integrated with the racket frame by passing the string through holes formed in the throatpiece which string upon being tightened in cooperation with projections extending outwardly from the sides of the throatpiece and extending into holes formed in the racket frame structurally integrates the throatpiece and the frame. The projections formed on the side of the throatpiece and the frame holes within which they are received permit limited flexing rotation between the throatpiece and the frame which accommodates the torsional rotation experienced by the frame in the throatpiece area upon a ball impacting the racket.
