Description

Billiard cue table and manufacturing method for the same

The disclosure herein relates to a billiard cue table, and to a billiard cue table used in billiards.

Unless otherwise indicated herein, the contents described in this identification are not prior art to the claims of this application, and the description in this identification is not admitted to be prior art.

In general, the billiard cue table used for billiards is manufactured using materials including wood, glass fiber, carbon fiber, graphite, and carbon fiber. There is a downside to losing.

In addition, in the case of a billiard cue table made of maple wood, which is traditionally used as a billiard cue, there is a disadvantage in that the manufacturing process is complicated and the manufacturing cost is increased because the elasticity is weak and other materials are added to increase the elasticity.

In this regard, Korean Patent Application Laid-Open No. 10-2020-0085993 discloses a coupling structure of a billiard cue and a method of combining the same, and Korean Patent Publication No. 10-2061248 discloses a cue table with improved bending prevention and striking force of the billiard cue. A manufacturing method thereof is disclosed.

However, the existing inventions do not disclose a technique for improving the elasticity of the cue table using only wood.

It is to provide a billiard cue table made of wood with improved elasticity and eco-friendly production.

In addition, it is not limited to the technical problems as described above, and it is obvious that another technical problem may be derived from the following description.

According to an embodiment of the disclosure, the billiard cue table is formed by processing a plywood member formed by bonding the outer and inner bars of a plurality of boards formed in a plate shape to each other.

In addition, the boards may be manufactured by flattening the bamboo nodes of the bamboo raw materials having an arc-shaped cross-section divided in the longitudinal direction of the bamboo and processing the cross-section into a plate shape.

The billiard cue table manufacturing method includes a processing step of grinding the outer and inner stems of split wood raw materials, a flattening step of processing the processed wood raw materials into a plate shape to produce boards, and bonding the outer and inner boards of the boards so that they are surface-coupled to each other. and a cue processing step of processing the bonded boards in the form of a billiard cue table.

In addition, in the processing step, the blades are rotated through an abrasive member having blades protruding outside the cylindrical body to grind or remove the protruding portions from the outer and inner stems of the wood raw materials.

According to an embodiment disclosed in the present specification, the billiard cue table is manufactured by attaching and processing the processed bamboo boards so that the outer layer corresponding to the outer skin and the inner band corresponding to the inner skin are positioned on opposite sides of each other. This has the advantage of improving the elasticity of the billiard cue table without the need to attach it.

In addition, the billiard cue table can be manufactured to improve the bonding force with each other by using the knurled parts of bamboo, and has the advantage of effectively removing the knurled parts of the bamboo through a polishing device.

In addition, since the effects of the present invention described as described above are naturally exhibited by the configuration of the described content regardless of whether the inventor recognizes it, the above-described effects are only a few effects according to the described content, and all effects identified or actual by the inventor should not be accepted as having been described.

In addition, the effect of the present invention should be further understood by the overall description of the specification, and even if it is not described in an explicit sentence, a person of ordinary skill in the art to which the described content belongs through this specification has such an effect. If it is an effect that can be recognized as the effect, it should be viewed as the effect described in the present specification.
