发明名称 LONG STRING TENNIS RACQUET
摘要 <p>A tennis racquet has a standard overall length and strung surface width. The length of the strung surface is elongated to 14.5 inches or more, e.g., 14.9 inches, and formed as an egg shape to produce improved stability while retaining good power. In a preferred embodiment, the ends of the main and cross strings engage the frame in a staggered configuration such that the strings engage the outermost crossing string on the surface facing one side of the center stringing plane and engage the frame on opposite side of the central stringing plane.</p>
