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
- 1. Field of the Invention
- 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.
- 2. Description of the Prior Art
- Baseball bat is an essential tool for baseball game and normally made of different materials. As shown in
FIG. 7 , atraditional baseball bat 80 is normally made of raw wood, however, the natural raw wood includes inherent grains along which the structure strength of thebaseball bat 80 is the weakest. Since thebaseball 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 thebaseball bat 80. Thereby, it can be found that thebaseball bat 80 which is made of the single piece of raw wood has short service life and increases the replacement cost. - The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
- 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.
- To achieve the above objective, a baseball bat structure in accordance with the present invention comprises a center portion and at least one sheet-shaped wind wooden unit.
- The center portion is formed into a round bar.
- The at least one sheet-shaped wind wooden unit includes plural spaced grain portions, the at least one sheet-shaped wind wooden unit is wound around the center portion to form plural layers of wind wooden unit, and 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. After being wound around the center portion, the at least one wind wooden unit will be processed into a desired bat shape.
- 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.

FIG. 1 is an exploded view of a baseball bat structure in accordance with the present invention; -
FIG. 2 is an exploded view of another baseball bat structure in accordance with the present invention; -
FIG. 3 is a combinational view of the baseball bat structure in accordance with the present invention ofFIG. 1 . -
FIG. 4 is a cross-sectional view of the baseball bat structure in accordance with the present invention ofFIG. 1 ; -
FIG. 5 is a partial enlarged view of the baseball bat structure in accordance with the present invention ofFIG. 1 ; -
FIG. 6 is a flow chart of a method for making a baseball bat structure in accordance with the present invention; and -
FIG. 7 is a schematic view of a conventional baseball bat. - The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
- Referring to
FIGS. 1-6 , a baseball bat structure in accordance with a preferred embodiment of the present invention comprises acenter portion 10, and at least one windwooden unit 20. - The
center portion 10 includes plural centerportion forming units 11. The plural centerportion forming units 11 in the present embodiment are thin wood sheets. The centerportion forming units 11 are laminated one upon another and then pressed and rolled into a round bar. The respective centerportion forming units 11 include plural spacedgrain portions 111 and are arranged in such a manner that a direction of the grain of thegrain portions 111 of one centerportion forming unit 11 is different from that of thegrain portions 111 of a neighboring centerportion forming units 11. - In the present embodiment, as shown in
FIG. 1 , the baseball bat structure comprises plural sheet-shaped windwooden units 20 each of which includes plural spacedgrain portions 21. The windwooden units 20 are laminated one upon another and wound around thecenter portion 10 to form a round structure with plural layers of windwooden units 20 on thecenter portion 10. The windwooden units 20 are arranged in such a manner that a direction of the grain of thegrain portions 21 of one layer of windwooden unit 20 is different from that of thegrain portions 21 of a neighboring layer of windwooden unit 20. After that, the round structure formed by winding the windwooden units 20 around thecenter portion 10 will be processed into a baseball bat shape. In addition, as shown inFIG. 2 , the baseball bat structure in accordance with the present invention can also only comprise a single windwooden unit 20 as long as it is long enough to continuously wind around thecenter portion 10 to cause layers of lamination of the windwooden unit 20 over thecenter portion 10, and a direction of the grain of thegrain portions 21 of one layer of windwooden unit 20 is different from that of thegrain portions 21 of a neighboring layer of windwooden unit 20. - The aforementioned is the summary of the positional and structural relationship of the respective components of the preferred embodiment in accordance with the present invention.
- For a better understanding of the present invention, its operation and function, reference should be made to
FIG. 3 : - Due the fact that the baseball bat structure in accordance with the present invention is made in such a way that the wind
wooden units 20 are wound around thecenter portion 10 to form a round structure, and then the round structure is machined into a desired bat, furthermore, the windwooden units 20 are laminated structures, the direction of the grain of thegrain portions 21 of one layer of windwooden unit 20 is different from that of thegrain portions 21 of a neighboring layer of windwooden unit 20, and the hitting portion of the bat that is used to hit a baseball is the windwooden units 20, the windwooden units 20 can provide a better elasticity as compared with the conventional bat made of a single piece of raw wood. Furthermore, since thegrain portions 21 have a different grain direction and are arranged in a staggered manner with respect to thegrain portions 21 of a neighboring layer of windwooden unit 20, when the baseball bat structure is subjected to a hitting force during hitting process, the force will be shared by the respective windwooden units 20, thus strengthening the structural strength of the baseball bat structure and make the baseball bat structure less likely to crack. - A method for making the baseball bat structure in accordance with the present invention, as shown in
FIG. 6 , comprises the steps of: - forming a center portion by pressing 40: plural center
portion forming units 11 are laminated one upon another and then pressed and rolled to form acenter portion 10 in the form of a round bar; - winding wind wooden unit 50: at least one wind
wooden unit 20 is applied with adhesive thereon and then wound around thecenter portion 10; - pressing 60: after being wound around the
center portion 10, the at least one windwooden unit 20 will be pressed to be more closely connected to thecenter portion 10; and - processing 70: after being pressed, the at least one wind
wooden unit 20 will be processed into a baseball bat shape. - With the above method, the baseball bat structure which has long service life and enhanced structure strength in accordance with the present invention can be made.
- While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
