Abstract: In a racquet, particularly a tennis racquet, having a handle (8) and a stretcher frame secured via a throat region (2) for stringing in which the cross-section of the stretcher frame measured transversely to the stringing has at least one section of largest dimension, the cross-section (a, b, c) of the stretcher frame in the throat region (2) and in the region of the racquet head (3) remote from the throat region is greater than in the region of the stretcher frame lying therebetween, whereby the cross-section (c) in the region of the racquet head (3) remote from the throat region is greater than the cross-section (b) in the throat region.

Abstract: A process for the production of a ball game racket frame, in particular a tennis racket, squash racket or badminton racket frame, with a head and a shaft, in which at least the head and/or the shaft is made of a fiber-reinforced plastic as a hollow body, an injectable matrix, optionally with a reinforcing fiber material and an inert gas under pressure, in particular N.sub.2, is injected into a mold to form the hollow space of the hollow body.

Abstract: A device for the protection of strings on the frame of a racket, such as for example, a tennis racket, comprises a band-like body which includes a plurality of tubular sleeves spaced a distance corresponding to the distance of bores in the frame of the racket. The band-like body further includes a peripheral groove which groove is in open connection with the tubular sleeves. The strings are placed into the peripheral groove and are strung through the tubular sleeves. The band-like body has protruding wall parts located on the side of the groove facing the tubular sleeves, which wall parts are connected with lateral parts of the body that overlap the frame. The protruding wall parts close the peripheral groove so that the strings lie protected within the peripheral groove.
