  • Patent number: 4366959
    Abstract: A racket for tennis and similar games in which the density of the strings in the central part of the strung surface is increased by incorporting a middle zone formed of a continuous length of stringing material, in which zone the strings are arranged in a pattern such that, at one of their ends, an adjacent pair of strings is immobilized relative to the frame at a common fixing point, while at their respective other ends, the strings are affixed to different fixing points. The pairs of strings having a common fixing point are not directly interconnected at the common fixing point, i.e., a path between one string affixed to a fixing point to which a second string is also affixed cannot be traced between the first string and the second string without passing through another fixing point. Only one interconnecting length of stringing material extends between adjacent fixing points.
