A games racket frame (5) particularly for tennis has a novel stringing system in which individual holes are used for main- and cross-strings and the holes lie in one of two notional planes (1,2) parallel to the plane (3) of interlaced main- and cross-strings such that successive string ends enter holes positioned in different notional planes and for over two-thirds of the total number of main- and cross-strings both ends of each string go through holes in the same notional plane. |

| Dans une raquette de tennis ou de squash les cordes (22, 24) sont montées sans frottement sur le cadre (12) et disposées sur la surface du cadre de façon que deux brins parallèles (22c, 22d) de la même corde soient distants d'au moins un diamètre de balle. Entre ces deux brins parallèles sont disposés deux autres brins (24d) qui appartiennent à une autre corde (24). Cette disposition des cordes permet de distribuer la tension consécutive à un coup sur la balle dans des zones qui n'ont pas été en contact avec celle-ci. | ||||||

A racket has a hand grip (13) joined to a frame having a shank region (11) and flaring outwards in a throat region (12) and extending around a generally oval ball-hitting region stand by transverse strings (17) and longitudinal strings (15). A central plurality of the strings (15) have a strung length at least 30% longer than all other strings in the network and that this central plurality includes at least one third (⅓) of all the longitudinal strings in the network. The longer longitudinal strings are strung with at least 30% more tension than all other strings in the network so that the longer strung length and the greater tension causes the longer longitudinal strings to provide a greater share in the transverse strangs of the string force that decelerates a ball penetrating the string network in the central region occupied by the longer longitudinal strings. |

In particular as a high performance game racket frame including at least one generally tubular, substantially circular pivot element located at least partially within a substantially circular mating recess on at least one portion of an outside-facing peripheral surface of the head frame profile that can rotate to cooperate with at least one string. The pivot element can rest upon at least a portion of the mating recess and therefore can have at least one adjoining surface portion. In order to reduce friction, adjoining surface(s) can be coated with a suitable anti-friction agent such as silicone or it can include a “frictionless” repelling permanent magnet portion capable of sustaining magnetic levitation between the two parts. Alternatively, at least a portion of the adjoining surfaces can include communicating electromagnetic friction plates in order to control the rate at which the pivot element rotates. | ||||||

| The netting structure of a fiber-made racket comprises a racket frame and several supporting parts. The racket frame is formed with upper and lower racket frames made of the fibrous material, and internal and external penetration netting areas are formed around between the upper and lower racket frames. Several supporting parts are provided in the netting area, a couple of parts adjacent to each other are lengthways stationary in the netting area of racket, and the threads of the racket pass through the couple of supporting parts and cross vertically and horizontally in the racket frame to form a hit area. Thanks to the interval of distance of thread passing between the netting area and the supporting parts, it is easy and fast to pass the threads, reducing the area of net threads contacting with the racket frames to increase the flexibility of hit area at the time of hitting. | ||||||

| In a racket frame, a yoke part is disposed between left and right portions of a bifurcated throat part continuous with a head part and with a shaft part. A ball-hitting face is formed with the yoke part and the head part. The head part and the yoke part have a plurality of string holes formed in penetration therethrough to insert longitudinal and transverse strings therethrough. Longitudinal string holes formed outside left and right sides of the yoke part connected with the left and right portions of the throat part are extended to the throat part to form extended longitudinal string holes open on an outer surface of the throat part. | ||||||
