摘要： A generally oval tennis racket characterized in that its strung surface comprises five zones: a central zone (A) including the geometric center (M) and the center of percussion (P) and having at least three cross strings; and on either side thereof two zones (B and C) each having at least three cross strings whose average length exceeds that of the cross string in the central zone (A). This construction increases the area (sweet spot) over which resilience is substantially uniform.

摘要： A badminton racquet includes a head, a shaft, and a Y-joint connecting the head to the shaft. The Y-joint geometry offers improved transmission of stress from the head to the shaft, and the resulting increased length of the center longitudinal strings improves power. Preferably, the frame has an improved aerodynamic profile, and a kick shaft to produce greater head speed at the point of impact.

摘要： Provided herein are racquets, such as sports racquets. The racquets generally comprise a head frame with a curved side rim and substantially parallel straight top and bottom rims and handle affixed to the head frame between the top rim and rims. A plurality of openings are equally spaced through the head frame and a portion of the handle and a plurality of strings comprising a net pass through the openings. The length of the top rim of the head frame is greater than the bottom rim. The handle connects to the head frame at an angle of about 140° to 150°.

摘要： A racquet includes polyester, monofilament racquet string and a frame extending along a longitudinal axis and including a head portion coupled to a handle portion. The head portion includes a hoop having inner and outer peripheral walls. The hoop defines a head size having maximum longitudinal and transverse dimensions, a, and, b, respectively. The dimension a is at least 1.2 times the dimension b. The inner peripheral wall includes string holes. The string has a diameter within the range of 1.10 to 1.55 millimeters. The string forms a string bed of interlaced main and cross string segments. Each of the cross segments transversely extends from one of the string holes to another, and each of the main segments longitudinally extends from one of the string holes to another. The string bed has at least one more main segment than cross segment. At least one of the main segments contacting the tennis ball exhibits a snap back velocity of at least 1 meter per second.

摘要： A tennis racket which includes a main frame portion having an oval shape which is defined by a top portion, side portions; and a yoke portion, a grip portion contiguous with the yoke portion, and a netting stretched in the oval main frame by main strings and cross strings to form a ball striking face with a sweet area provided therein, wherein the ratio of the rigidity in the ball striking direction, which is the thickness direction of the frame to the rigidity in the main string direction, and the ratio of the rigidity in the ball striking direction, which is the thickness direction of the frame, to the rigidity in the cross string direction, are each set to be larger than 1.00 and smaller than 2.00, and the rigidity ratio of the frame within the ball striking face including the ratio of the rigidity in the main string direction to the rigidity in the cross string direction of said strings is set to be smaller than 1.00.

摘要： The tennis racket has a strung surface which is larger than the strung surface of a conventional racket, particularly in regard to its dimension in a longitudinal direction from the frame tip toward the handle shaft of the racket. The conventional length, weight, and balance which have proven necessary for good playing characteristics for all tennis rackets of the past have been maintained. The racket has unexpectedly achieved increased strength and a combination of advantages in playing characteristics without resort to weights, springs, or other complications previously proposed. The racket has a zone of high coefficient of restitution, much larger than that of conventional rackets, extending in a longitudinal direction from the region of the center of percussion to a point 11/4 inch from the throat of the racket, thereby taking maximum advantage of the location of the center of percussion of the racket. The zone of high coefficient of restitution is also wider with respect to the corresponding zone on conventional rackets.

摘要： A tennis racquet having a polar moment of inertia similar to conventional length racquets, but being longer than conventional racquets with the same or larger size strung surface. Having the same polar moment of inertia as a well playing conventional racquet gives it the same "feel" but with greater reach, and, if desired, a larger strung surface.
