Bat apparatus

Abstract

The system provides an improved and durable bat, that is also resistant to vibration, while still maximizing performance characteristics. In one embodiment, a thermal heat shrink to encase the bat with a more durable, crack and chip resistant outer layer. In one embodiment, polyolefin is used as the heat shrink materials. The heat shrink material also reduces vibration effects significantly.

What is claimed is: 
     
         1 . A bat comprising:
 a tubular frame having a circular cross-section, the tubular frame including a large diameter hitting portion, an intermediate tapering portion, and a small diameter handle portion;   a shrink wrap layer formed on a surface of the large diameter hitting portion; and   a tubular insert positioned within the large diameter hitting portion of the tubular frame, wherein the tubular insert is positioned in the tubular frame by foam having a diameter greater than a diameter of the tubular insert, such that there is a gap between the tubular insert and the tubular frame.   
     
     
         2 . The bat of  claim 1  wherein the shrink wrap layer includes a preprinted logo formed thereon. 
     
     
         3 . The bat of  claim 1  wherein the shrink wrap layer comprises polyolefin. 
     
     
         4 . The bat of  claim 1  further including a tubular insert positioned within the large diameter hitting portion of the tubular frame such that there is a gap between the tubular insert and the tubular frame. 
     
     
         5 . The bat of  claim 4  wherein the tubular insert further includes a shrink wrap layer formed on a surface of the insert. 
     
     
         6 . The bat of  claim 1  wherein the tubular frame is comprised of a substrate and a plurality of polyolefin and thermosetting layers.
