Embodiment Construction

[0054] Fig. 1 shows a configuration example of a baseball bat according to the present invention, Figure 1A For front view and left side view, Figure 1B is the B-B sectional view, Figure 1C is the C-C end view, Figure 1D It is a D-D end view. The structure of the baseball bat 11 of the present invention is such that a reinforcing core 12 with a rectangular cross-section disposed at the center penetrates both ends and surrounds an outer peripheral material 13 formed of bamboo pieces 24 on the outside. As the reinforcing core 12 in this figure, Natural hickory wood. This reinforcing core 12 is that the length of one side is processed into a square section of 16mm by drying the log, as shown in the B-B sectional view.

[0055] The peripheral material 13 covering the outer side of the reinforcement core 12 is formed by bonding a plurality of bamboo sheets 24 . Bamboo chip 24 is the elongated rectangular shape that the bamboo that will be felled is split along the fiber dir...

Abstract

There is provided a baseball bat that has performance similar to that of the conventional wooden bat and moreover is excellent in terms of cost and resource conservation. For this baseball bat 11, a reinforcing core 12 having a rectangular cross section is arranged in the center of the cross section thereof continuously so as to penetrate both end thereof, bamboo pieces 24 are laminated around thereinforcing core 12, and an adhesive is caused to permeate into the contact surface between the reinforcing core 12 and the bamboo pieces 24 evenly under a pressure, by which firm bonding can be attained. In addition, by using a material that is hard and has a large specific gravity as compared with bamboo, such as hickory or reinforced wood, as the reinforcing core 12, the flexural rigidity is enhanced as a whole, and the weight is increased. Therefore, the characteristics and feel in use are improved as compared with the conventional bamboo bat, and the baseball bat 11 can be used as a substitute for a wooden bat. Bamboo, hickory, and reinforced wood have no problem in terms of resource conservation, can reduce the product price, and can lower the consumption of scarce resources such asserrata.

Description

technical field [0001] The present invention relates to a baseball bat used in baseball games. Background technique [0002] Baseball bats need to withstand the strong impact of hitting, and the types of wood that can be used as hard baseball bats are limited to ash, maple, and birch. However, since these woods are restricted by the place of production and it takes a long time to grow, resource depletion has intensified in recent years, and the price of wooden bats tends to rise. As a substitute for a wooden bat, a metal bat is known, but since it is light in weight and has a large coefficient of repulsion, it is advantageous to the hitting side, so there is a problem that the game cannot be played smoothly. For this reason, metal bats are not allowed in professional baseball, and there are various restrictions even in amateur baseball. [0003] Due to such a background, as a substitute for conventional wooden bats, bonded bats bonded with wood chips or bamboo chips are wi...
