DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view of a shaft or bat of a billiard cue having a three-layer structure according to an embodiment of the present invention. FIG. FIG. 2 is a perspective view of a billet cue shaft or bat according to an embodiment in which a hole penetrates the center of the three-layer structure.
[0012]
The shaft 1 or bat 2 of the billiard cue shown in FIG. 1 which is the first embodiment of the present invention is an elongated truncated cone-shaped rod-shaped body having a slightly tapered outer shape. The outer peripheral surface layer 5 has a three-layer structure made of different materials. One layer of these three-layer structures is alloy, light alloy, metal, wood, plywood, natural leather, synthetic leather, thread, natural rubber, synthetic rubber, soft synthetic resin, hard synthetic resin, glass fiber, carbon fiber, etc. It is made of a material such as reinforced plastic fiber, and is made using a material different from the next adjacent layer. In this embodiment, the first layer 3 that is the rod center portion 3 is made of carbon fiber, the second layer 4 that is the intermediate layer 4 is made of wood, and the third layer 5 that is the outer peripheral surface layer 5 is made of synthetic leather. In other embodiments, other materials may be used.
[0013]
A method for manufacturing the shaft 1 or the bat 2 of the billiard cue according to the first embodiment of the present invention will be described. The shaft 1 or bat 2 of the billiard cue is the rod center portion 3 of the rod-like body. The first layer 3 is alloy, light alloy, metal, wood, plywood, natural leather, synthetic leather, yarn, natural rubber, synthetic rubber. It is formed in a truncated cone shape or a cylindrical shape by one kind of material made of soft synthetic resin, hard synthetic resin, glass fiber, reinforced plastic fiber such as carbon fiber or the like.
[0014]
In the case where the first layer 3 has a truncated cone shape, the shape of the second layer 4 which is the intermediate layer 4 is a conical ring shape having a substantially constant thickness, which is different from the material forming the first layer 3. It is made of one kind of material. The second layer 4 is adhered to the outer peripheral surface of the first layer 3 with an adhesive or the like.
[0015]
The third layer 5, which is the outer peripheral surface layer 5, is provided further on the outer periphery of the second layer 4, and like the second layer 4, has a constant conical ring shape with a substantially constant thickness, which forms the second layer 4. The first layer 3 may be the same type as the first layer 3. The third layer 5 is adhered to the outer peripheral surface of the second layer 4 with an adhesive or the like.
[0016]
When the first layer 3 is formed in a columnar shape, the cylindrical body of the second layer 4 or the third layer 5 is formed in a truncated cone shape having a tapered outer periphery.
[0017]
In the third embodiment shown in FIG. 3, a through hole 6 penetrating in the longitudinal direction of the rod is provided at the center of the first layer 3 forming the rod center portion 3 of the three-layer structure of the first embodiment. In the third embodiment, the first layer 3 has a cylindrical shape.
[0018]
The shaft 1 or bat 2 of the billiard cue shown in FIG. 2, which is the second embodiment of the present invention, is an elongated truncated cone-shaped rod whose outer shape is slightly tapered, and is composed of a rod center 3 and an outer peripheral surface layer. 5 has a two-layer structure made of two different materials. Each one of these two-layer structures is alloy, light alloy, metal, wood, plywood, natural leather, synthetic leather, thread, natural rubber, synthetic rubber, soft synthetic resin, hard synthetic resin, glass fiber, carbon fiber It is made of a material such as reinforced plastic fiber, and is made using a material different from the adjacent layer.
[0019]
The manufacturing method of the shaft 1 or the bat 2 of the billiard cue according to the second embodiment of the present invention will be described. The billiard cue shaft 1 or bat 2 is a rod-shaped rod center 3 made of alloy, light alloy, metal, wood, plywood, natural leather, synthetic leather, thread, natural rubber, synthetic rubber, soft synthetic resin, hard It is formed in a truncated cone shape or a columnar shape with one kind of material made of reinforced plastic fibers such as synthetic resin, glass fiber, and carbon fiber.
[0020]
When the rod center portion 3 has a truncated cone shape, the shape of the outer peripheral surface layer 5 is a conical ring shape having a substantially constant thickness, which is a kind of material different from the material forming the rod center portion 3. It is formed. The outer peripheral surface layer 5 is attached to the outer peripheral surface of the rod center portion 3 with an adhesive or the like.
[0021]
When the rod center portion 3 is formed in a columnar shape, the cylindrical body of the outer peripheral surface layer 5 is formed in a truncated cone shape having a tapered outer periphery.
[0022]
In addition to the three-layer structure of the first embodiment and the two-layer structure of the second embodiment, it is also possible to form four or more layers with different materials.
[0023]
When a ball is struck with the billiard cue according to the present invention, the cue manufactured with a single material is transmitted to a hand holding a different feel. As a result, curves and spins that are not possible in the past may be applied.
[0024]
【The invention's effect】
The billiard cue of the present invention is stronger and stronger than the billiard cue manufactured with a conventional single material, and is less likely to break or break.
[0025]
Due to the combination of materials with different properties, there is a possibility of unpredictable strength compared to the conventional case, touch feeling transmitted to the hand when hitting the ball, There is an effect that the curving of the curve may change slightly and the unexpectedness of the competition may occur.
