    • A ball bat comprising a bat frame in a generally cylindrical configuration. The bat has an essentially cylindrical hitting area and a handle area remote from the hitting area and with a tapering transition zone therebetween. The bat frame is fabricated of a composite material of fibers in a matrix binder. A cylindrical recess is formed in the hitting area and has an annular inner face and parallel end faces at the ends of the recess. An annular insert metal with an interior cylindrical surface is in contact with the inner face of the recess and with parallel end faces in contact with the end faces of the recess and a cylindrical exterior surface essentially flush with the portions of the bat frame on opposite sides of the recess.
    • 一种球棒,包括大致圆柱形构型的蝙蝠框架。 蝙蝠具有基本上圆柱形的击球区域和远离击球区域的手柄区域,并且在其间具有渐缩的过渡区域。 蝙蝠框架由基体粘合剂中的纤维的复合材料制成。 在打击区域中形成圆柱形凹部,并且在凹部的端部处具有环形内表面和平行端面。 具有内部圆柱形表面的环形插入金属与凹部的内表面接触,并且平行的端面与凹部的端面接触,并且圆柱形外表面基本上与相对侧的蝙蝠框架的部分齐平 的凹陷。
