Title:
SPORTS RACQUET WITH FRAME OPENINGS
Document Type and Number:
WIPO Patent Application WO2004075996
Kind Code:
A3
Abstract:
A sports racquet has a plurality of opposed string holes for anchoring the ends of the strings. at least one pair of contiguous string holes are replaced with an enlarged string hole having opposed bearing surfaces for securing the ends of a pair of contiguous string segments. Preferably, a plurality of contiguous enlarged string holes are employed along the sides, tip, and heel or throat bridge of the racquet, in order to reduce the weight of the racquet head. Also, preferably, the enlarged string holes are defined by a pair of opposed interior walls of the frame extending between the frame's inner and outer surfaces, thereby forming a truss-like internal structure for stiffening the frame. Moreover, the frame preferably has interior wall portions that extend between the string holes. Such wall portions lie in the string bed plane and underlie the string portions on the exterior of the frame.
