发明名称 Racquet configured with fewer cross strings than main strings
摘要 A racquet includes polyester, monofilament racquet string and a frame extending along a longitudinal axis and including a head portion coupled to a handle portion. The head portion includes a hoop having inner and outer peripheral walls. The hoop defines a head size having maximum longitudinal and transverse dimensions, a , and, b , respectively. The dimension a is at least 1.2 times the dimension b . The inner peripheral wall includes string holes. The string has a diameter within the range of 1.10 to 1.55 millimeters. The string forms a string bed of interlaced main and cross string segments. Each of the cross segments transversely extends from one of the string holes to another, and each of the main segments longitudinally extends from one of the string holes to another. The string bed has at least one more main segment than cross segment, At least one of the main segments contacting the tennis ball exhibits a snap back velocity of at least 1 meter per second.
