201	Tensionable racket having unique stringing pattern	US561595	1983-11-30	US4595201A	1986-06-17	Herwig Fischer
The lengths of string (22 and 24) of a racket, more specially a tennis or squash racket, are trained over bend points of the frame (12) with a low degree of friction and are so strung backwards and forwards across the frame that the spacing between two parallel strings of the same length of string (22) is at least equal to the radius of a ball. Between these strings (22c and 22d) there are parallel strings (24d), that are parts of other string lengths (24). This system of stringing the frame makes it posible for tension forces produced on ball impact to be transmitted to other parts of the array of strings not contacting the ball.
202	Racquet having strings of equal length	US445737	1982-11-30	US4512575A	1985-04-23	Kuo-Nan Tzeng
A racquet for use in playing tennis and other ball and racquet games has a stringing pattern which comprises a pair of longitudinal central strings (5') located symmetrically one on each side of the central longitudinal axis of the racquet frame, and four additional strings disposed outwardly of each of the central strings. The stringing pattern also comprises a pair of transverse strings (5") located symmetrically one on each side of the central transverse axis at a distance of approximately 40% of the length (L) of the strung surface as measured from the inner edge of the racquet throat (3). Also, both in directions toward the tip of the racquet frame (6) and toward the throat (3) four additional strings are arranged. Additional longitudinal and transverse strings are provided that are arranged outwardly from the aforementioned strings. An effective strike area is constituted by the cross-linking of the ten longitudinal and ten transverse strings corresponding to the scope of that area, the inner edges of the frame tip (16) and of the throat (3) being parallel and of identical curvature and the inner edges of both sides of the frame being arranged at minimum curvature.
203	String load apportioned racket	US376592	1982-05-10	US4437662A	1984-03-20	Tsai C. Soong
Longitudinal strings 15 or 25 of tennis or other sports rackets 10 or 20 are lengthened to be at least 30% longer than transverse strings 17 or 27 and are strung with at least 30% more tension than the transverse strings. The longitudinal strings are also functionally related in length and tension to the transverse strings to effectively apportion to the longer longitudinal strings from approximately half to substantially more than half of the string force for decelerating a ball pentrating the string network as the ball is hit. The functional relationship for selecting appropriate lengths and tensions for the longer and shorter strings is mathematically derived, analyzed, and related to practical working mechanics of a string network. The advantages of lengthening, tightening, and apportioning more of the load to the longitudinal strings include a higher coefficient of restitution for the string network; a larger and more responsive sweet spot area; smaller hysteresis losses from string stretching; less interstring friction and ball deformation; higher velocity ball rebound; better shot control; and less torque shock to the arm of the user from off center hits.

205	Racquet means and method of stringing same	US812602	1977-07-05	US4172596A	1979-10-30	Gaylord C. Linden
A method of stringing tennis racquets, and the racquets resulting therefrom, in which the string is secured to the racquet frame in the form of two isolated sections, namely, a main string section and a cross string section. Each of these two sections is formed from a single length of string and is tied off onto itself so that either section can be replaced without disturbing the other one. Because each of the two string sections is tied off onto itself, the racquet can be easily repaired by the mere replacement of either section found to be defective.

A tennis racket head is strung with string sections between frame support points formed into zig-zag segments which have multiple junction points with other string sections to hold the strings in the zig-zag pattern. In a preferred embodiment, the segments are arranged in parallel tiers, and weave over and under intermediate strings between junctions. An apparatus and method for stringing the racket is included. A simple tension adjustment can be added to the racket, which adjusts the tension over the entire playing surface.
207	Tennis racket and stringing method	US716425	1976-08-23	US4131279A	1978-12-26	John M. Ogden
A tennis racket and stringing method are disclosed wherein the resulting racket has a more uniform main string to cross string tensioning. The uniform tensioning provides a consistent playing surface throughout the entire stringed area. The center main strings are first tensioned and the remaining main strings are tensioned by working outwardly from the center strings toward the sides. The cross strings are interwoven with the main strings beginning from the center and working outwardly.
208	Tennis racket string network	US736585	1976-10-28	US4093220A	1978-06-06	Mike Prewarski
In rackets for tennis and like games, a string network consisting of longitudinal and cross strings interwoven alternately to construct a regular `basket weave` pattern at the center of the striking face and woven in a special manner at the sides and at one or both ends of the string network. At the sides the cross strings are woven over and under two or three longitudinal strings with consecutive cross strings alternating the over and under pattern. At the ends, above and below the said center striking area, two or three cross strings are woven identically and farther outward towards the ends of the string network, the over and under pattern is alternated with one, two or three consecutive cross strings.
209	Method of stringing a game racket	US15583071	1971-06-23	US3834699A	1974-09-10	PASS R
In tennis rackets and the like a faster and more efficient method of stringing racket frames wherein the strings are inserted and tensioned within the frame without interweaving the longitudinal and latitudinal strings. The net thus formed is than consolidated into a unified structure by bonding the longitudinal strings to the latitudinal strings at each point that the longitudinal strings cross the latitudinal strings.

A sports racquet having a plurality of string port holes (20), i.e enlarged string holes having two inwardly facing string bearing surfaces which are spaced apart by a distance corresponding to the distance between two contiguous main strings or cross strings, and conventional string holes (18) is formed of a single tube of prepreg material. When molded, mold members (34) press opposed portions of the prepreg tube into contact with one another, and shape the opposed portions and the surrounding prepreg material (37) into a string port hole blanks (40). The portion of the pressed-together material which initially blocks the string port hole (20) is removed after molding so that the string port holes (20) extend through the frame. Alternatively, the mold members (64) cause the prepreg tube to follow a serpentine shape, thereby defining string port holes (62) which are open alternately along the top and bottom surface of the frame. A pair of cover rings (74) may be secured to the top and bottom racquet surfaces (70,72) to cover the open sides of the string port holes (62).
