billiard cue forelimb

Abstract

A billiard cue forelimb comprising a tubular shell and a core. The shell has a first end, a second end, a predetermined wall thickness and a long axis extending from the first end to the second end. The shell includes a main shell and a secondary shell overlapped with the main shell, each shell is made of fiber-reinforced plastic material and arranged along the circumferential direction of the shell. The main shell layer includes a plurality of first fiber bundles, each of the first fiber bundles runs parallel to the long axis of the shell. The sub-shell also includes a plurality of second fiber bundles, each of which runs perpendicular to the long axis of the shell. The core is made of plastic foam and arranged inside the shell. As a result, the lack of unidirectionality and uneven density distribution of the grain of the wood material can be improved, the flow displacement of the main shell fiber bundles during the manufacturing process can be avoided, and the shock when hitting the ball can be absorbed and the shock caused by hitting the ball can be reduced. the noise produced.

Description

technical field [0001] The invention relates to the structure of a billiard cue, in particular to a billiard cue forelimb mainly made of fiber-reinforced plastic composite material. Background technique [0002] The currently generally used billiard cue is usually composed of a forelimb (Shaft) and a rear handle (Butt). It is easy to be bent by moisture, the texture is not unidirectional, the density distribution is uneven, and the hardness cannot be adjusted, which reduces the accuracy and stability of the user's hitting. Although fiber composite materials have been used to replace wooden materials, such as those disclosed in U.S. Patent No. 4,816,203 and U.S. Patent No. 6,736,733, these cue cue forelimbs made of fiber composite materials have not only solved the problem that wooden materials are prone to moisture and bending. In addition, there is no improvement in the lack of unidirectional texture of wood materials, uneven density distribution, and inability to adjust s...
