Baseball bat structure and method for making the same

Abstract

A baseball bat structure includes a center portion in the form of a round bar, and at least one sheet-shaped wind wooden unit wound around the center portion. A direction of the grain of the grain portions of one layer of wind wood unit is different from that of the grain portions of a neighboring layer of wind wood unit, so that the grain portions of one layer of wind wood unit are arranged in a staggered manner with respect to the grain portions of the neighboring layer of wind wood unit, and therefore, the staggered grain portions can enhance the structure strength. Being laminated structures, the wind wood units can offer a better structure elasticity to the baseball bat structure, making the baseball bat structure less likely to crack while extending the service life.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a tool for baseball game; and more particularly to a baseball bat structure and a method for making the same.[0003]2. Description of the Prior Art[0004]Baseball bat is an essential tool for baseball game and normally made of different materials. As shown in FIG. 7, a traditional baseball bat 80 is normally made of raw wood, however, the natural raw wood includes inherent grains along which the structure strength of the baseball bat 80 is the weakest. Since the baseball bat 80 is made of a single piece of raw wood and will be subjected to a hitting force each time hitting the baseball, it is more likely to crack along the grains. Such cracks cannot be repaired, so that the user has to abandon the baseball bat 80. Thereby, it can be found that the baseball bat 80 which is made of the single piece of raw wood has short service life and increases the replacement cost.[0005]The present invent...

AI Technical Summary

Benefits of technology

[0006]The primary objective of the present invention is to provide baseball bat structure which has both better structure strength and better structure elasticity and further has longer service life.

[0010]Since the wind wooden unit is wound around the center portion, and the grain portions have a different grain direction and are arranged in a staggered manner with respect to the grain portions of a neighboring layer of wind wooden unit, both the structure strength and the structure elasticity of the baseball bat structure can be enhanced, thus making the baseball bat structure less likely to crack while extending the service life of the baseball bat structure.

Problems solved by technology

Such cracks cannot be repaired, so that the user has to abandon the baseball bat 80.

Thereby, it can be found that the baseball bat 80 which is made of the single piece of raw wood has short service life and increases the replacement cost.
