  • Patent number: 5316316
    Abstract: A tennis racket handle is disclosed having an improved handle configuration which eliminates protruding points which may impact the hypothenar eminence of the palm. The butt end of the handle has a cross-sectional shape that is dis-similar to the cross-sectional shape of a middle portion of the handle, approximately 12 cm from the butt end. The butt end and middle portion are connected by a transition zone polyhedron has a number of planar sides against which the hypothenar eminence may bear to eliminate the discomfort of the protruding points of the known handles.

  • Patent number: 4964645
    Abstract: This invention relates to a structurally-improved racket handle designed to increase the area of the palm in contact with the racket handle thereby allowing a better grip than presently available racket handles. This affords greater power transfer while returning serves, volleying, serving, and other strokes due to the provision of an oblique surface 11 cm. in length that extends from the bottom end of the racket handle in alignment with its central axis and is beveled from the butt in a graduated, constant, or curved manner. The resulting graduated, constant, or curved surfaces yields a naturally formed wedge-shaped edge that fits snugly into the muscles and bones of the palm and muscles of each finger, and enables the palm to naturally assume a tight, circular, yet comfortable grip.

  • Patent number: 4836544
    Abstract: This invention relates to an improved structure for a racket handle, particularly denoting a design which has a hooking/gripping and force applying point for the forefingers and separate areas for the hooking/holding of the middle, the force and the little fingers set in a descending order from the upper direction of the racket handle. Also designed are a circular swollen convexed section to facilitate the handle-holding motion performed by the center of the palm and the section of hypothenar emience keeping in close touch with the handle to provide similar functions to facilitate the performance of handle holding. This unique design will keep the palm of the player in close and comfortable touch with the racket handle and further match it with the natural structure of the elbow when a ball is being struck, so as to reduce the possibility of sporting injury and help beginners form a proper handle-holding posture to the ultimate end of bringing the skill of racket playing to its full play.
