发明名称 Racquet with string positioning elements
摘要 A racquet having two sets of strings crossing one another and preferably interwoven, and having at least one string positioning element engaging and extending along a string of one of the sets and contacting a plurality of strings of the second set in a relation preventing lateral deflection thereof at the points at which the strings cross one another, while permitting deflection of the strings of the second set at locations between those cross points. This enables the application of spin forces to a ball by such deflection while at the same time minimizing wear by virtue of retention of the strings against relative motion at the crossing points. The positioning elements are preferably tubular and desirably disposed about the transverse strings of a racquet, and may contain notches for receiving successive longitudinal strings in locating relation.
