球拍框架
摘要：
一种球拍框架（2），包括：拍头（4），拍柄（8），和从拍头（4）延伸至拍柄（8）的一对拍喉（6）。拍喉在低负载范围（从5kgf至15kgf）内的抗弯刚度G15等于或者大于600kgf/mm并且小于或者等于900kgf/mm。拍喉在高负载范围（从45kgf至55kgf）内的抗弯刚度G55等于或者大于900kgf/mm并且小于或者等于1200kgf/mm。抗弯刚度G15和抗弯刚度G55的刚度比（G15/G55）大于或者等于0.70并且小于或者等于0.85。
摘要（英）：

A racket frame 2 includes a head 4, a shaft 8, and a pair of throats 6 extending from the head 4 to the shaft 8. A flexural rigidity G 15 of the throats 6 in a low load range (from 5 kgf to 15 kgf) is equal to or greater than 600 kgf/mm but equal to or less than 900 kgf/mm. A flexural rigidity G 55 of the throats 6 in a high load range (from 45 kgf to 55 kgf) is equal to or greater than 900 kgf/mm but equal to or less than 1200 kgf/mm. A rigidity ratio (G 15 /G 55 ) of the flexural rigidity G 15 and the flexural rigidity G 55 is equal to or greater than 0.70 but equal to or less than 0.85.
