摘要： PROBLEM TO BE SOLVED: To provide a racquet capable of imparting more spin to a ball.SOLUTION: A racquet includes a frame having a head portion coupled to a handle portion, and a string bed of interlaced cross and main string segments. The head portion includes a hoop having inner and outer peripheral walls. The hoop defines a head size having a maximum longitudinal and transverse dimensions, a and b, respectively. The dimension a is at least 1.2 times longer than the dimension b. The inner peripheral wall includes string holes. 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 cross segment closest to the handle portion and the end point of a segment of the longitudinal dimension a, on a the handle portion side, define a second longitudinal dimension c. The ratio of the dimension a to the dimension c is at least 6.5. The string bed has at least one more main segment than cross segment.

摘要： PROBLEM TO BE SOLVED: To provide a tennis racket capable of raising repulsive force, attaining both of uniformity of repulsion property and control property, and reducing an impact and a vibration, by devising a new technology to the conventional shape, structure and function of the tennis racket. SOLUTION: The shape of a face in the tennis racket is made to have projected and recessed curved lines. The grids of strings are made to be the minimum at the center part of a sweet spot, density of the grid is enlarged from the center part toward a frame, and the number of the grids is made to be the maximum in the frame part. The deformation structure includes: projected curved lines whose extension is made to be the maximum, in the frame part of the warp and weft with the minimum grid density in the vertical and horizontal directions of the face frame; and curved lines to be extended in a recessed shape in the middle and divided parts of the maximum adjacent projected shapes. An impact/vibration absorbing function is provided to the four parts with the maximum extension or to the whole frame. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To bring back a racket without waiting for a long time when buying it, to provide various kinds of rackets, to inexpensively repair them, and also to reduce a quantity of trash at the time of repair by stringing center part guts and a peripheral part gut as separate bodies. SOLUTION: In a store, rackets each with a gut strung only in a peripheral part are placed. Then, center part guts 2a and 2b are strung with a strength which is desired by a user in the store when he/she buys it. In a stringing method, one center part gut which is independent from the peripheral part one is used at first, its one end side is inserted through a through-hole 5c and its tip 2c is tied and connected at the inner side of a frame 1. Then, the gut coming to an outside from the through-hole 5c is inserted through respective through-holes 5a, the center part gut 2a in a longitudinal direction is strung after meandering, the center part gut 2b in a horizontal direction is continuously strung and the tip 2d is inserted through a through-hole 5d so as to be tied and fixed at the inside of the frame 1.

摘要： PURPOSE:To improve controllability in the case of hitting a ball at an end part on the yoke part side of a gut surface, and improve repulsive property in the case of hitting the ball at a center part or on the top part side. CONSTITUTION:A boundary line is set at a position of 2/5 of the whole length L in a Y-direction of the longer axis of a gut surface is set along the Y- direction of the longer axis from an end part 4a on the side of a yoke part 2b of the gut surface toward the top part side. A range surrounded by the end part 4a on the yoke part 2b side and the boundary line is a first range A1. A range of 3/5 of the whole length L of the Y-direction of the longer axis of the gut surface from the boundary line toward the top part 2c side along the Y-direction of the longer axis is a second range A2. A ratio between an average value of length in the longer axis Y-direction of mesh M formed by intersections of guts in the longer axis Y-direction and guts in the shorter axis direction in the first range A1, and an average value of length in the longer axis Y-direction of the mesh M in the second range A2 is set to be 0.3 or more and 1.0 or less.

摘要： PURPOSE:To provide the racket frame for tennis which substantially prevents a tennis elbow by specifying the compressive rigidity in a vertical string extension direction and cross string extension direction to specific values or above. CONSTITUTION:The width of the frame string extension part 11 of the racket frame 10 is continuously changed to suppress the cause of distortion. Namely, the parts of a frame top A and yoke center part D where the distortion is liable to appear largest when the vertical strings G1 and the cross strings G2 are extended to attain 3:1 tension ratio are formed to the max. width. A side upper part B and side lower part C are then formed next broadest. The part P, Q, R where the deformation is most hardly induced are formed in a thin direction so that the compressive rigidity in the vertical strong extension direction and the cross string extension direction should be >=330N/mm and >=60N/mm, respectively. As a result, the distortion is hardly caused in the frame string extension part of the racket frame even if the vertical and cross strings are so extended as to be 3:1.
