Ball bat

Abstract

A ball bat comprising an elongated support piece, a first elongated wood piece and a second elongated wood piece. The elongated support piece has an elongated upper surface and an elongated lower surface opposite to the elongated upper surface. The elongated support piece has plural radial bores aligned axially and spaced from each other. The elongated upper surface of the elongated support piece faces upwards and is attached to the first elongated wood piece, and the elongated lower surface of the elongated support piece faces downwards and is attached to the second elongated wood piece, so that the elongated support piece is embedded and fixed between the first and the second elongated wood piece. The overall weight of the ball bat and its center of gravity can be adjusted according to the number and allocation of the radial bores.

What is claimed is: 
     
         1 . A ball bat comprising:
 a handle section;   a hitting section;   a tapered section connected between the handle section and the hitting section;   an elongated support piece;   a first elongated wood piece; and   a second elongated wood piece;   the elongated support piece having an elongated upper surface and an elongated lower surface opposite to the elongated upper surface, the elongated support piece having plural radial bores aligned axially and spaced from each other, the elongated upper surface of the elongated support piece facing upwards and attached to the first elongated wood piece, and the elongated lower surface of the elongated support piece facing downwards and attached to the second elongated wood piece, thereby embedding and fixing the elongated support piece between the first elongated wood piece and the second elongated wood piece.   
     
     
         2 . The ball bat according to  claim 1 , wherein the plural radial bores aligned axially and spaced from each other are disposed on the hitting section. 
     
     
         3 . The ball bat according to  claim 1 , wherein the plural radial bores aligned axially and spaced from each other are disposed on the hitting section and the tapered section. 
     
     
         4 . The ball bat according to  claim 1 , wherein the elongated support piece, the first elongated wood piece and the second elongated wood piece extend from the handle section to the hitting section, respectively. 
     
     
         5 . The ball bat according to  claim 4 , wherein the plural radial bores aligned axially and spaced from each other are disposed on the hitting section. 
     
     
         6 . The ball bat according to  claim 4 , wherein the plural radial bores aligned axially and spaced from each other are disposed on the hitting section and the tapered section. 
     
     
         7 . The ball bat according to  claim 1  further comprising a cladding layer, which is bonded to the exterior of the stacked first elongated wood piece, the elongated support piece, and the second elongated wood piece. 
     
     
         8 . The ball bat according to  claim 7 , wherein the plural radial bores aligned axially and spaced from each other are disposed on the hitting section. 
     
     
         9 . The ball bat according to  claim 7 , wherein the plural radial bores aligned axially and spaced from each other are disposed on the hitting section and the tapered section.
