    • Industry regulatory organizations have created performance restrictions for ball bats. The present invention relates to a ball bat with an internal impact dampening means. More particularly, the present invention relates to a ball bat with a handle, a barrel, and a central tube positioned coaxially within the barrel. The central tube includes at least one restriction member capable of limiting the deformation experienced by the ball bat upon impact of a ball. Precisely limiting the deformation of the ball bat allows the present invention to achieve, but not exceed, performance substantially equal to the maximum performance allowed by industry regulatory organizations and maintain that level of performance over a substantial length of the ball bat.
    • 行业监管机构已经为球棒创造了业绩限制。 本发明涉及具有内部冲击阻尼装置的球槌。 更具体地,本发明涉及一种具有手柄,筒体和同心地位于筒体内的中心管的球棒。 中心管包括至少一个能够限制球撞击球时经历的变形的限制构件。 精确地限制球蝙蝠的变形使得本发明能够实现但不超过行业监管机构所允许的最大性能基本上等于其性能,并且在相当长的球蝙蝠上保持这种性能水平。
