Benefits of technology
The present invention is about a fiber-reinforced resin bat with a safety means to prevent damage caused by projectiles during use. The safety means does not affect the strength or performance of the bat. The bat has a tubular body with multiple layers made of fiber-reinforced resin sheets. The safety means is located on the middle section of the tubular body and includes a first separating member, a second separating member, and a safety member. The first and second separating members are attached to adjacent layers of the tubular body, while the safety member has a side portion between the two separating members and a main portion between the first and second members. The safety member is securely attached to the tubular body, preventing resin material from seeping into it, while still allowing for the safety member to break or shatter during use.
Problems solved by technology
The result is that the tapered transition portion is prone to break because the stress producing during use will be concentrated thereon.
In other words, when the bat is broken or shattered during use, the barrel portion constantly becomes a dangerous projectile to injure both players and spectators.

Embodiment Construction
[0020]Referring firstly to FIGS. 1 to 4, reference numeral 10 generally designates a baseball bat according to a first preferred embodiment of the present invention. The bat 10 includes a tubular body 12, a barrel portion 14, a handle portion 16 and a tapered portion 18. The barrel portion 14 is generally made of wooden materials. The handle portion 16 and tapered portion 18 are made of PU materials. The bat 10 further includes a safety means 20.
[0021]The tubular body 12 extends along a longitudinal axis X-X′ and includes a plurality of layers 22 made of fiber-reinforced resin sheets. Here, the fiber-reinforced resin sheet means a sheet made of a material of fiber reinforcement impregnated in a resin matrix. The resin matrix can be a thermoplastic resin or a thermosetting resin. Generally, the fibers of the fiber reinforcement are long fibers selected from the group consisting of glass fiber, boron fiber, carbon fiber and aramid fiber.
[0022]The tubular body 12 includes a front secti...

A safety bat for striking balls or the like comprises a tubular body and a safety means. The tubular body extends along a longitudinal axis and includes a plurality of layers made of fiber-reinforced resin sheets. The safety means is disposed on the tubular body to eliminate the danger of damage caused by projectiles from the bat that breaks or shatters during use and such a safety means does not alter the bat's strength or performance.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to bats for striking balls or the like and more particularly to a bat with a safety means for linking broken portions of the bat when it breaks during use which otherwise would become dangerous projectiles.[0003]2. Description of the Related Art[0004]It was known that the conventional ball bats are generally made of wood, metal, fiber-reinforced resin material, or a combination of them. Yet for having good performance and durability, the bat constructed entirely with fiber-reinforced resin materials predominated over the other conventional ball bats. However such bats usually has a tubular body including a plurality of layers made of fiber-reinforced resin sheets and shaped with a handle portion, a barrel portion, and a tapered transition portion between the handle portion and the barrel portion. The result is that the tapered transition portion is prone to break because the stress producin...
