A sports racquet which utilizes non-circular strings is disclosed. The strings are threaded to the racquet in the normal manner with their flat or larger surfaces facing outwardly. The strings are thus arranged in a grid pattern with their flat or larger surfaces forming the striking area.

A sports racket, for tennis and the like sports, has an elongated handle attached to a head having a racket face, which is spanned by a uniform string structure. The head has four sides, forming a non-elliptical shape, in which the opposite sides are substantially parallel. Longitudinal strings, all of which are substantially identical in length and run essentially parallel to each other, and transversal strings, all of which are substantially identical in length and run essentially parallel to ...

A racquet in which the area of the string which manifests relatively true rebound of the ball, the so-called "sweet spot", is maximized. To achieve this condition the strings are so tensioned or so structured that the deflection produced by impact of the ball near the outer periphery of the racquet is substantially equal to the deflection near the center of the racquet. The strings are subjected to lower tension near the outer periphery than near the center of the racquet or they are of smaller ...

A game racket having an elastic net and a frame molded in unison, the net comprising non-linear elements which work primarily in bending and whose cross sectional area increases toward the center of the net.

A tennis racket in which a handle is provided with a frame of generally oval outline having stringing therein forming arrays of strings running transverse to one another and forming crossing points, with respective inserts being provided at at least some of the crossing points between the strings forming same, the inserts each comprising an absorbent pad impregnated with a liquid lubricant in the form of an oil for reducing friction between the strings at the crossing points, the pads being of s...

A tennis racket strung with a string grid, each strand of which has a cross-section defining a polygon with concave sides thus providing the grid strands with longitudinally extending concave surfaces which meet to form longitudinally extending sharp edges. At each junction between the strands of the string grid the sharp edges contact each other only at four sharply defined spaced points thus locking the strands to each other at each junction. In weaving the string grid substantial rectilineari...

The invention relates to stringing for a racket for tennis, badminton or the like, consisting of individual, in each parallel transverse and longitudinal strings which are crossed in the manner of a linen weave to give a ready-made network and at the same time arranged spaced apart from one another and which have outwardly protruding, free, cut-off ends for individual fastening in a racket frame and are held in their mutual position by a removable aligning device.

A prefabricated string assembly for use in the stringing of tennis rackets or the like consists of individual transverse and longitudinal strings crossed with one another in the manner of a fabric weave to form a network having outwardly projecting free string ends for fastening to a racket frame. The transverse and longitudinal strings are arranged such that the strings extending in a first direction have a denser setting than those extending in the transverse direction whereby a collecting zon...

A racket comprises a frame, a throat and a handle, within the frame a plurality of longitudinal and transverse strings form the strike surface, characterized in that at the position inside the frame near to the throat is provided with an elastic band extending transversely over the width of the strike surface, preferably intermitted at the center, which is preformed with a plurality of apertures in a number and at interval corresponding to the longitudinal strings, so that the longitudinal strin...
