摘要： A tennis racket or the like is provided with two similar frame elements formed of tubular material and secured together in parallel spaced relation. Sheaves are mounted on the frame elements in the space therebetween and stringing for the racket is passed about the sheaves and arranged so as to permit axial movement of the stringing to equalize or distribute the stress applied thereto during use. The stringing may consist of endless strands of wire, nylon or the like and tensioning means are mounted in the handle of the racket and connected to the stringing to vary and equalize the tension under which the stringing is maintained.

摘要： An adjustable throatless tennis racquet including a head portion formed of two similar members disposed in spaced relation with respect to one another and separated by a plurality of spacers fixedly maintained therebetween by a plurality of pin members, the racquet further including a plurality of sheaves rotatably mounted preferably around the spacers and including a peripheral groove about the exterior thereof to receive therein a string as in conventional tennis racquets however such that the stringing is performed in a diagonal fashion, the ends of the stringing secured to a connector member in the top of the handle portion of the frame such that by lateral movement of the connector portion the strings throughout the surface of the diagonally strung racquet will be allowed to move axially with respect to the string itself, the connector being laterally movable within a space defined by the parallel extending surfaces of the two similar members, the racquet further including a mechanism for adjusting of the tension of the stringing by varying the tension exerted on the connector member in a direction axially with respect to the handle.
