Problems solved by technology

Among them, the disadvantages of bats made entirely of wood are heavy weight, small hitting area, and fragile structure, and the user's hand will feel a large vibration when hitting the ball.
Although the bat made entirely of aluminum alloy is lighter in weight and stronger in structure than wooden bats, it still has problems such as small hitting area and inability to absorb shocks, and there are also dents in the hitting part and the Sometimes a sharp stick will be issued, such as a carbon fiber bat. Although it is light in weight and strong in structure, it still has a small hitting area and cannot effectively absorb the shock generated when hitting the ball. The seed bat is high, so the high price is not acceptable to ordinary consumers

Embodiment Construction

[0047] First, please refer to FIG. 1 , which shows a ball bat 10 according to a first preferred embodiment of the present invention, which has a grip portion 12 , a core tube 14 , an intermediate member 16 and a hitting portion 18 .

[0048] The handle 12 can be made of plastic, such as PU foam, or wood, and has a front end 121 , a rear end 122 and a body 123 whose outer diameter gradually increases from the rear end to the front end.

[0049] The core tube 14 is made of fiber-reinforced plastic, such as carbon fiber impregnated with epoxy resin, or metal, such as aluminum alloy, and is embedded in the axis of the grip portion 12 along the long axis of the bat. In other words, the length of the core tube 14 is longer than the handle portion 12, so that it has a bare section 142. In manufacturing, a shaft hole can be laid in the handle portion 12 and then the core tube 14 can be worn. Or place the core tube 14 in the center first and stick the handle portion 12 divided into sev...

Abstract

The invention relates to an improved bat which comprises a handle, a core pipe, a medium part and a ball-striking part. The handle is prepared by synthetic resin or timber; the external redial of the handles body is generally thin in front end and thick in rear end. The core pipe is prepared by fiber reinforced plastic (FRP) or metal and which is inside the handle. One end of core pipe projects the front end of handle a certain degree to form a bare section. The medium part which is posited on the bare section of the core pipe and on the inner side of ball-striking part has predetermined weight and elasticity. The ball-striking part which is connected with the handle to form an integer bat is prepared by metal or fiber reinforced plastic.

Description

technical field [0001] The present invention relates to ball hitting tools, and more particularly to an improved ball bat with increased hitting area and better shock absorption. Background technique [0002] Currently, tools for hitting a ball, such as baseball bats or softball bats, are generally made of wood, aluminum alloy or plastic composite materials. Among them, the disadvantages of the bat made entirely of wood are heavy weight, small hitting area, and fragile structure, and the user's hand will feel a large vibration when hitting the ball. Although the bat made entirely of aluminum alloy is lighter in weight and stronger in structure than wooden bats, it still has problems such as small hitting area and inability to absorb shocks, and there are also dents in the hitting part and the Sometimes a sharp stick will be issued, such as a carbon fiber bat. Although it is light in weight and strong in structure, it still has a small hitting area and cannot effectively abs...
