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 reinforcing member for a badminton racquet wherein the racquet extends along a longitudinal axis and includes a frame having a tubular hoop portion supporting a string bed and a tubular handle portion. The reinforcing member includes a generally T-shaped body having first and second sections. The first section has an outer surface that defines a first cross-sectional area measured about a longitudinal plane positioned generally perpendicular to the string bed. The second section longitudinally and outwardly extends from the first section. The second section has an outer surface that defines a second cross-sectional area measured about a transverse plane. The first cross-sectional area is at least 50 percent greater than the second cross-sectional area. The first and second sections are configured for placement within the hoop and handle portions of the frame, respectively.

摘要： PROBLEM TO BE SOLVED: To provide a racquet capable of imparting more spin to a ball.SOLUTION: A racquet includes polyester-made-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 frame body (2) is formed separately from a yoke (10) connecting right and left parts of the frame body (2) to each other. The yoke (10) and the frame body (2) are connected to each other by a mechanical connection means, with both ends of the yoke (10) in contact with the right and left parts of the frame body (2) in an area of not less than 10 cm (1.6 in ). A shear force generated when the racket frame (1) deforms is collectively applied to a connection surface of the frame body (2) and that of the yoke (10) to increase a vibration-damping performance of the racket frame (1).

摘要： PROBLEM TO BE SOLVED: To provide a racket frame which is light and stable in high rigidity, and has a proper vibration damping property and in which the vibration damping property can be controlled. SOLUTION: A frame main body 2 is independently formed from a yoke 10 which connects the left and right frame parts of the frame main body 2. The both ends of the yoke 10 are respectively joined with the left and right frame parts of the frame main body 2 in at least >=10 cm area and connected by a mechanical connecting means. A shearing force generated when the racket frame 1 is deformed is concentrated on the connected joining surfaces of the frame main body 2 and the yoke 10 so that vibration damping property is enhanced by this configuration.
