161	Tennis racket	US674826	1976-04-08	US4013289A	1977-03-22	Bernard Kaminstein
A tennis or squash racket is provided wherein, by changing the number of strings in the racket and rearranging their location the shock of the impact of the ball upon the racket is resiliently absorbed over a longer period of time than heretofore, and a better control of the ball is obtained. A center group of vertical strings is provided, wherein the strings are closely spaced about the center of the racket and two strings are positioned on either side of the center group which are further apart in the remaining racket space. There is a horizontal string group closely spaced principally about the center with a fewer number of strings on either side between the horizontal string group and the top and the bottom of the racket.
162	Game racket	US44211274	1974-02-13	US3912267A	1975-10-14	LYON EDWIN J
A game racket comprised of tubular metallic construction having a unique string support member extending throughout the interior of the tube and through holes provided in the surface of the inner periphery of the tubular frame in the area of the head portion of the racket. The support member is provided with a hook like configuration containing tension regulating abrasive resistant engaging members or pads to support and mount the string within the game racket such that the tension of the string can be varied and/or equalized by using various sizes of the tension regulator members within the string support extending through the tubular frame. The unique frame structure and string support structure also provides for horizontal lacing type of stringing for the racket.

955,733. Rackets. J. R. LACOSTE. March 29, 1961 [March 30, 1960], No. 11598/61. Heading A6D. In a tubular metal frame for a tennis or like racket of dumb-bell cross-section, the strings are attached to loops extending round the frame. As shown, the loops may be formed by winding a piano wire 17 spirally round the frame, the turns of the wire being located by a notched spacer strip 18. The strings are looped round the turns of wire 17 in the inner groove corresponding to the groove 8. The strip 18 may form part of the completed racket or may be removed. In a modification (Figs. 9 and 10, not shown), the strings are attached to an intermediate sinuous wire member which is bound to the inner periphery of the frame 5 by wire 17. Instead of being in spiral form, the wire may be applied to the frame in half hitches (Fig. 11, not shown). In other forms (Figs. 12-14, not shown), the wire is replaced by metallic rings which may be located by tubular or notched spacers. Metallic rings formed with inward projections (Fig. 15, not shown), are spaced by means of blobs of plastic on solder in groove 8. The frame may be made of hard chromium plated steel tube. Specification 955,732 is referred to.

177	Sport racquet	US12924994	2010-10-07	US20110152016A1	2011-06-23	Robert Gazzara; Mauro Pinaffo; Michel Pozzobon; Mauro Pezzato
The present invention relates to a method for manufacturing at least a portion of a sports racquet frame that comprises a step a) of providing a moldable tube structure containing a first inflatable bladder and a second inflatable bladder. The first and second inflatable bladders are positioned on opposite first and second regions of the moldable tube structure. At an intermediate region, the tube structure comprises one or more cross channels, which pass through the moldable tube structure. The method according to the present invention comprises also a further step b) of inserting said tube structure inside a mold forming a mold cavity of a desired shape. Mold members are inserted into the cross channels of the tube structure, so that the outer surface of the mold member faces the inner surface of the corresponding cross channel. The mold members have position and orientation that correspond to the position and orientation, along the string bed plane, of the string port holes, which are to be formed on said frame portion. The method, according to the present invention, comprises also a step c) of pressurizing the first and second bladders, so that the tube structure conforms to the shape of the mold, and heating the mold, so that the tube structure cures. The method, according to the present invention, comprises a further step d) of removing the cured tube structure from the mold cavity and removing the mold members from the cross channels.
178	Sports racquet with string port holes	US11584200	2006-10-20	US07935286B2	2011-05-03	Roberto Gazzara; Mauro Pinaffo; Michele Pozzobon; Mauro Pezzato
A sports racquet having a plurality of string port holes and conventional string holes is formed of a single tube of prepreg material. When molded, mold elements press opposed portions of the prepreg tube into contact with one another, and shape the adjoining prepreg material into a string port hole blanks. The portion of the pressed-together material which initially blocks the string port hole is removed after molding so that the string port holes extend through the frame. Alternatively, the mold elements cause the prepreg tube to follow a serpentine shape, thereby defining string port holes which are open alternately along the top and bottom surface of the frame. A pair of cover rings may be secured to the top and bottom racquet surfaces to cover the open sides of the string port holes.

An apparatus that lays strings on top of each other within a frame; the overlying of the strings, once the process is finish, will create the arrays of intersections between the vertical and horizontal strings that create the net in a racquet, such as a tennis racquet, or squash racquet. The apparatus is new, very useful and has of a main section, a complementary overlap cover for the main section, a way of securing and undoing the main section to and from the frame of the racquet, and an inlet and outlet passage for the strings to and from the main section. In addition, a preferred embodiment includes the main section with vertical and horizontal routes that overpass each other made of transparent plastic, and consisting of any number of vertical and horizontal routes. A preferred embodiment includes the complementary overlap with a design of any geometric shape.
