Bat structure

Abstract

A bat structure is disclosed. It comprises a hollow body having a gripping portion, an extension portion, a hitting portion, a supporting partition disposed in a hollow tube of the hitting portion, and an inner tube body disposed in the hollow body and extended from a side surface of the supporting partition, wherein the supporting partition and the inner tube body are integrally forged with the hollow body.

1 . A bat structure, comprising:
 a hollow body having a gripping portion, an extension portion, a hitting portion, the hitting portion having an open end, a supporting partition disposed in a hollow tube of the hitting portion, and an inner tube body extended from a side surface of the supporting partition in the hollow tube, the inner tube body forming a first vibration-absorbing space therein, and a second vibration-absorbing space formed between the inner tube body and an inner surface of a peripheral wall of the hollow tube, the first vibration-absorbing space being an empty space, wherein the supporting partition and the inner tube body are integrally forged with the hollow body; and   a lid correspondingly sealed at the open end of the hitting portion.   
     
     
         2 . As the bat structure claimed in  claim 1 , wherein the gripping portion, the extension portion, and the hitting portion of the hollow body are forged integrally. 
     
     
         3 . As the bat structure claimed in  claim 1 , wherein the hollow body is made of an aluminum material.
