A sports racket (1) comprises a racket body (2) having a longitudinal axis (3), said racket body (2) having a handle (4) and a frame (5), said frame (5) including a head part (6), a middle part (7), a throat element (8), and a shank element (9) connecting said throat element (8) to said handle (4); at least two string segment systems in a plane (10), one system comprising longitudinal string segments (12) running from the head part (6) towards the handle (4) in a direction substantially parallel to the longitudinal axis (3) of the racket, at least one different system comprising transverse string segments (11) running from one side of said axis (3) towards the opposite side in a direction substantially perpendicular to said axis (3), each string segment possessing two ends anchored on said members of the frame, said transverse string segments (11) and said longitudinal string segments (12) intersecting with one another; wherein a portion of said throat element (8) is provided with at least one opening (21) enabling a plurality of said longitudinal string segments (12) to pass through and be anchored in the region (30) between the throat element (8) and the handle (4), and at least for two longitudinal string segments, one on either side of the longitudinal axis (3), anchored in the region between the throat element (8) and the handle (4), there is no structural, load-carrying member between said side string segments and the outboard space beyond. The frame (5), which surrounds the string network (11, 12), is essentially not continuous.

A sports racket (20) having a frame (10) comprising a top portion (1), two opposed sides (2), a throat (3), a shank portion (4), a handle (5), and a string network which has longitudinal string segments (7) and cross string segments (9), the frame (10) comprising an odd number of longitudinal strings and a longitudinal central string (21) coinciding with the central longitudinal axis (8) of the racket whereby the string segments, their anchoring with the frame thereabouts, arrangement of accessories and attachments in the frame, such as grommet strips and bumper guard, are positioned so as to be an exact mirror image with respect to the central longitudinal axis of the frame, thus enhancing the balance, power and handling of the racket due to the symmetrically balanced arrangements.

Bei eine Saitenstrang oder einer Saite gleichbleibenden Durchmessers zum Bespannen eines Schlägers für Ballspiele, insbesondere eines Tennisschlägers, ist der Elastizitätsmodul des Saitenstranges bzw. der Saite abschnittsweise unterschiedlich.

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.

There is described a racket, particularly tennis or squash racket, in which the mean mesh surface area of the string network is at least equal to 170 mm² for a tennis racket and at least equal to 100 mm^z for a squash racket, whereby by mesh the geometrical figure is meant which lies completely enclosed between two pairs of strings crossing one another, such as they are present in a polygon defined by four straight lines which run two by two in parallel relationship with one another, and the lengths of which are equal to half the length of the longest axis in the one direction, and to half the length of the longest axis along a direction which crosses said first direction.
