Abstract: The tennis racket has the particularity that the cross-sectional area of the frame in the plane of the stringing of the head portion comprises locally widened zones opposite to each other in the region of greatest width of the head portion, measured perpendicular to the longitudinal axis in the plane of the stringing, and optionally one locally widened zone at the free end of the head portion.

Abstract: A tennis racket is disclosed which has a frame joined to a longitudinally extending handle on an axis of symmetry of the racket. A handle of the frame defines annular opening which is covered by stringing tensioned in a plane extending across the opening. Two connecting arms attach the handle to the frame and a reinforcement member between the two connecting arms defines a portion of the annular opening. The height of the main portion of the frame in a direction perpendicular to the stringing plane is at least essentially constant between the connecting arms and an end portion of the frame, the width of the frame in the main portion thereof being between about 50% and 75% of the frame height. Further, an end portion of the frame, including the top end thereof, has a cross section which increases from the main portion of the frame to the top end.
