发明名称 Racquet configured with fewer cross strings than main strings
摘要 A racquet including a frame having a head portion coupled to a handle portion, and a string bed of interlaced cross and main string segments. The head portion includes a hoop having inner and outer peripheral walls. The hoop defines a head size having a 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 cross segments transversely extend from one of the string holes to another, and the main segments longitudinally extend from one of the string holes to another. The cross segment closest to the handle portion and the end point of the longitudinal dimension, a, closest to the handle portion define a second longitudinal dimension, c. The ratio of dimension a to dimension c is at least 6.5. The string bed has at least one more main segment than cross segment.

主权项 1. A tennis racquet configured for use with a string bed formed of a plurality of cross string segments interlaced with a plurality of main string segments, the racquet comprising: a frame extending along a longitudinal axis and including a head portion coupled to a handle portion, the head portion including a hoop having inner and outer peripheral walls, the hoop defining a head size of the racquet, the head size being within the range of 93 square inches to 120 square inches, having a maximum longitudinal dimension, a, and having a maximum transverse dimension, b, the longitudinal dimension a being at least 1.2 times the transverse dimension b, the inner peripheral wall including a plurality of cross-string holes and a plurality of main string holes, each of the cross string holes configured for receiving one end of one of the cross string segments and each of the main string holes configured for receiving one end of one of the main string segments, the number of main string holes being greater than the number of cross string holes such that the string bed configured for use with the racquet has one, two or three fewer cross string segments than main string segments, the number of main string holes and the number of cross string holes being such that the plurality of main string segments of the string bed is within the range of 14 to 20 main string segments, and the plurality of cross string segments of the string bed is within the range of 11 to 19 cross string segments.
