Abstract
Description
Technical Field
[0001] This utility model relates to the field of competitive sports, and is mainly applied to billiards. Specifically, it relates to a wood-carbon fiber cue stick. Background Technology
[0002] Billiards, as an important part of competitive sports, relies on the quality of its equipment to affect the feel and vibration of the ball when struck. If the vibration transmission is unstable, it will affect the accuracy of the ball's movement.
[0003] In billiards, the most common method is to strike the billiard ball with a cue stick, which is a consumable item in the sport. Currently, the cue stick is made of wood, with weights added inside, and the exterior is painted and decorated to provide a comfortable grip and personalization options.
[0004] Due to factors such as wood type, processing method, and storage time, billiard cues made of wood are prone to instability, mold, deformation, or cracking, leading to instability in the cue itself and an inability to guarantee consistency in every shot. Furthermore, wooden cues are slender and difficult to process, making it challenging to ensure complete flatness and smoothness of the cue body. Uneven surfaces can affect the trajectory of the shot, impacting subsequent production. Additionally, the wood requires further sanding and processing, making the process complex.
[0005] Wooden cues are prone to warping and bending due to the inherent properties of the material. Most people rarely perform immediate maintenance on their cues after playing billiards. While hand sweat during play may not significantly affect the cue in the short term, over time, the humidity and temperature of the hands, as well as the humidity and temperature of the environment, can damage the wooden cue, causing issues such as paint peeling and cracking. High-end cues are often accompanied by exorbitant prices. Therefore, extending the lifespan of the cue while ensuring accurate shots is a major concern for billiards players.
[0006] Furthermore, in the daily maintenance of billiard cues, as products of the factory, in order to ensure consistent quality and customer satisfaction, some cues may have bending or appearance problems due to customer issues, which require after-sales service from the factory, thus increasing operating and maintenance costs.
[0007] Billiard cues made entirely of carbon fiber are also complicated to manufacture and expensive. While conventional billiard cues with carbon fiber grips and wooden forelimbs can combine the advantages of both materials, the wooden forelimbs are still prone to deformation and cracking. Furthermore, because they are not molded in one piece, the junction between the two materials is prone to loosening, deformation, and gaps, which can negatively impact the accuracy of the shot.
[0008] Therefore, how to improve the quality and accuracy of billiard cues at the lowest possible cost has become a major technical concern. Utility Model Content
[0009] To prevent cue stick deformation and improve striking accuracy, this invention provides a wood-carbon fiber cue stick. This cue stick, through the combination of wood and carbon fiber blocks, solves the technical problems of easy deformation and difficulty in guaranteeing striking accuracy.
[0010] The solution adopted by this utility model to solve the technical problem is:
[0011] The wood-carbon fiber golf club comprises wood blocks and carbon fiber blocks, wherein the carbon fiber blocks and wood blocks are arranged in a spaced-out, overlapping manner, and the enclosed cross section forms a circular shape to constitute the wood-carbon fiber golf club.
[0012] The carbon fiber block has a cross-shaped cross-section consisting of a straight line, an L-shape, or a trapezoidal shape, and is spaced between two fan-shaped wooden blocks. It is then connected and fixed to the wooden blocks by gluing.
[0013] The wooden block is a longitudinally elongated fan-shaped block, with one end gradually narrowing and the other end being relatively large, forming a cone shape.
[0014] The wooden block is a number of equally divided sector-shaped blocks, whose edges fit together to form a circle in cross section. One end of the block gradually narrows into a cone shape, and they are combined to form a cone, which serves as the cue stick.
[0015] The carbon fiber block consists of multiple carbon fiber blocks in a straight line, spaced between two adjacent wooden blocks, and glued together to form a wood-bonded carbon fiber billiard cue.
[0016] Furthermore, the carbon fiber blocks are several L-shaped cross-sections with included angles, and the L-shaped carbon fiber blocks are arranged circumferentially to clamp the wooden blocks, forming a wood-carbon fiber club.
[0017] Furthermore, the carbon fiber block is a set, consisting of two isosceles trapezoidal blocks of the same shape, area, and size. One trapezoidal carbon fiber block has a through groove at the midpoint of its lower base, and the other trapezoidal carbon fiber block has a through groove at the midpoint of its upper base. The two through grooves interlock to form a cross shape. The wooden block is placed at the opening of each set of carbon fiber blocks in the cross shape, with its fan-shaped edge fitting against both sides of the cross-shaped carbon fiber block.
[0018] Positive effects: The wood-carbon fiber cue of this utility model uses fan-shaped wood blocks and carbon fiber blocks to form a cue. The requirements for wood are lower than those for solid wood cues, which improves the utilization rate of wood, saves energy and is environmentally friendly. Therefore, it can reduce the production cost of the cue while ensuring its quality. At the same time, it takes into account the advantages of carbon fiber and wood blocks, reduces the deformation of the wood-carbon fiber cue, and allows for inspection of the manufacturing quality of the wood blocks during the manufacturing process, reducing rework and saving manpower and resources.
[0019] The wood-carbon fiber billiard cue of this invention, by adding a carbon fiber block as the inner core of the cue, can form a stable internal support for the fan-shaped wood block. At the same time, it can correct and reduce the deformation and internal cracking of the billiard cue caused by factors such as hand sweat and environmental humidity, and reduce the impact of insects on the billiard cue to a certain extent. In this way, it avoids the impact of twisting and deformation of pure wood cue on the accuracy of the shot, reduces maintenance costs, and increases the service life of the billiard cue.
[0020] Furthermore, since this utility model utilizes a combination of carbon fiber blocks and wood blocks to produce a billiard cue, it leverages the inherent waterproof, sweatproof, deformation-resistant, heat-resistant, and cold-resistant properties of carbon fiber while retaining the texture of wood. This improves the manufacturing precision of the billiard cue while reducing production costs. Compared to pure wooden cues, it exhibits less deformation; compared to pure carbon fiber cues, it is heavier, easier to grip, and cheaper. This reduces the production and manufacturing costs of the billiard cue, saving manpower and resources. At the same time, the use of carbon fiber can reduce the bending and deformation of wood, thereby reducing the deformation of the billiard cue during use and ensuring the accuracy of the shot.
[0021] Meanwhile, due to the uniform and delicate structure of carbon fiber, it has high vibration damping and strong rigidity. It can also improve the rebound of the ball when it hits, reduce the impact of vibration on the trajectory of the billiard ball, and absorb impact better, making billiards more accurate and reducing the impact of equipment on the fairness of competitive sports.
[0022] Therefore, it is suitable for use as a billiard cue. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0039] In this utility model, all embodiments, implementation methods, and features can be combined with each other without contradiction or conflict. In this utility model, conventional equipment, devices, and components can be commercially available or self-made based on the disclosure of this utility model. In this utility model, to highlight the key points, some conventional operations and equipment, devices, and components are omitted or only briefly described.
[0040] Referring to the accompanying drawings, the wood-carbon fiber golf club includes a wooden block 1 and a carbon fiber block 0. The carbon fiber block 0 and the wooden block 1 are arranged in a spaced-out, overlapping manner, and the enclosed cross section is circular to form the wood-carbon fiber golf club.
[0041] The cross section of the carbon fiber block 0 can be straight, L-shaped or cross-shaped, and is spaced between two fan-shaped wooden blocks 1. It is connected and fixed to the wooden blocks 1 by adhesive methods such as spraying or pouring.
[0042] The wooden block 1 is a longitudinally elongated fan-shaped block, with one end gradually narrowing and the other end being relatively large, forming a cone shape.
[0043] This utility model provides an embodiment in which the wooden block 1 is an equally divided sector block, with at least four blocks. The right-angled sides of the blocks fit together to form a circle in cross-section. One end of the blocks gradually narrows into a cone shape, and they are combined to form a cone shape, which serves as the cue stick.
[0044] At this time, the carbon fiber block 0 is in a straight line, consisting of three carbon fiber blocks 0. One longer carbon fiber block 0 is set on the diameter of the cross-section circle of the wooden block 1, and the other two shorter carbon fiber blocks 0 are set along the center of the longer carbon fiber block 0 and perpendicular to the longer carbon fiber block 0. Regardless of whether the shorter or longer carbon fiber blocks are combined, they should be perpendicular to each other and their diameter should be equal to the diameter of the wooden block 1.
[0045] In this embodiment, the carbon fiber block 0 is fixedly combined with the wood block 1 by gluing. The wood block 1 and the carbon fiber block 0 are glued together alternately. One wood block 1 is glued to a longer carbon fiber block 0, and another shorter carbon fiber block 0 is glued to the other side of the wood block 1. Another wood block 1 is glued to the other side of the shorter carbon fiber block 0. The other side of the wood block 1 is glued to the other end of the longer carbon fiber block 0. Another wood block 1 is glued to the other side of the longer carbon fiber block 0. Then, a third shorter carbon fiber block 3 is glued together. A fourth wood block 1 is glued to the other side of the third shorter carbon fiber block 0.
[0046] The fabrication of this embodiment:
[0047] First, make four equal fan-shaped wooden blocks 1, ensuring that their equal-sized ends are on the same side. Take one of the wooden blocks 1 as the reference block, and place a longer carbon fiber block 0 along the virtual diameter direction of the reference wooden block 1. Apply glue to fix the carbon fiber block 0 to the wooden block 1. Then, take a shorter carbon fiber block 0 and place it along the vertical line from the center point of the longer carbon fiber block 0, so that the shorter carbon fiber block 0 and the longer carbon fiber block 0 are perpendicular to each other. Apply glue to fix it. Next, take another wooden block 1, apply glue to both sides, and fix it between the longer carbon fiber block 0 and the shorter carbon fiber block 0. The other side is the same, so it will not be repeated here. This method allows the manufacturing quality of the wooden blocks 1 to be checked during the installation process. If the longitudinal side of the wooden block 1 protrudes or is recessed into the extended side of the carbon fiber block 0 after gluing, it is considered that the manufacturing of the wooden block 1 is unqualified and it is returned for repair. If the longitudinal side of the wooden block 1 is consistent with the extended side of the carbon fiber block 0, the quality of the cue is qualified and can be delivered directly without further quality inspection, further saving the cue manufacturing time.
[0048] As one of the above embodiments, the wooden block 1 can also be six or eight pieces, with the cross-section circumference equally divided. Each equally divided sector-shaped wooden block has the same arc length, arc radius, and side length. The sides fit together to form a circle. One end of the longitudinal direction gradually shrinks into a cone shape. The combination forms a cone shape, which serves as the billiard cue stick.
[0049] At this time, the carbon fiber blocks 0 are all short blocks of equal length, and are spaced apart from the equally divided wooden blocks 1. In other words, a carbon fiber block 0 is sandwiched between two wooden blocks 1.
[0050] In this embodiment, the fixing connection between the carbon fiber block 0 and the wood block 1 can be consistent with the above embodiment, that is, glue is applied to both sides of the wood block 1 or the carbon fiber block 0 to fix them to each other; or a pipe clamp can be used, which is fitted on the outer circumference of the billiard cue semi-finished product composed of the completely spaced wood blocks 1 and carbon fiber blocks 0. In order to ensure that no deformation occurs, at least three pipe clamps should be fitted on the billiard cue semi-finished product body. Four pipe clamps, five pipe clamps or any number of pipe clamps can also be used as needed. The selection of the number of pipe clamps can be arbitrarily selected according to the conventions of those skilled in the art, and is not considered as a constraint or protection point limiting this utility model; after fixing the wood block 1 and the carbon fiber block 0 with pipe clamps, glue can be poured along the gap at one end (larger end or smaller end) of the billiard cue semi-finished product until it overflows along the other end and the outer circumference surface without bubbles. Alternatively, glue can be poured along the gap in the longitudinal direction of the billiard cue semi-finished product until no bubbles overflow, thus completing the production of the wood-carbon fiber billiard cue.
[0051] In another embodiment of this utility model, the carbon fiber block 0 has an L-shaped cross section and there are two of them. The wooden block 1 is a four-part sector block. The shape of the wooden block 1 is the same as in other embodiments. The two sides of the L-shaped carbon fiber block 0 are equal in length and perpendicular to each other, that is, the opening of the L-shaped carbon fiber block 0 is 90°.
[0052] In this embodiment, during installation, first, a wooden block 1 is vertically attached to the outside of the opening edge of the L-shaped carbon fiber block 0, then another L-shaped carbon fiber block 0 is placed so that the two carbon fiber blocks 0 are mirror images and perpendicular. Another wooden block 1 is attached between the two L-shaped carbon fiber blocks 0, and finally, a wooden block 1 is attached between the two L-shaped carbon fiber blocks 0 to ensure the accuracy of the billiard cue. Similarly, this embodiment can also use pipe clamps to assist in installation.
[0053] In this embodiment, since carbon fiber itself has a certain degree of hardness, when the carbon fiber block 0 is an L-shaped block with equal side lengths and an opening of 90°, if the angle resistance is felt when installing the wooden block 1, it is considered that the L-shaped carbon fiber block 0 is not installed correctly. Loosening the L-shaped carbon fiber block 0 and keeping it in a free state will make it vertical, further ensuring installation accuracy, while reducing quality inspection steps and saving manpower and resources.
[0054] In this embodiment, the carbon fiber block 0 can also be L-shaped with an included angle of 60°, and the two sides of the L-shape are of equal length. There are three such blocks. Correspondingly, the wooden blocks 1 are selected as six-part sector blocks. Any one of the wooden blocks 1 is taken as a reference block and sandwiched between the L-shape blocks with an included angle of 60°. When the wooden block 1 and the side of the L-shaped carbon fiber block 0 with an included angle of 60° are completely in contact, the quality of the wooden block 1 is qualified. Continue to install other wooden blocks 1 and set carbon fiber blocks 0 with intervals between wooden blocks 1 until the billiard cue is completed. Similarly, this embodiment can also use pipe clamps to assist in the installation.
[0055] As one option in this embodiment, the carbon fiber block 0 has an L-shaped cross-section with an included angle of 60° and has six blocks. The wooden block 1 is a six-part sector block. The shape of the wooden block 1 is the same as in other embodiments. The two sides of the L-shaped carbon fiber block 0 are equal in length, and the opening angle of the L-shaped carbon fiber block 0 is 60°.
[0056] In this embodiment, the installation involves first inserting a wooden block 1 into the opening of each carbon fiber block 0. After all six carbon fiber blocks 0 are installed, they are joined together to form a circular cross-section, thus completing the production of the wood-coated carbon fiber billiard cue. This embodiment can further improve the production speed of the wood-coated carbon fiber billiard cue. In this implementation, the six L-shaped carbon fiber blocks 0 with a 60° angle are hollow at the center after being joined together. The narrower end of the cone-shaped billiard cue forms the cue head. The hollow cue head can be used to further fix the tip and at the same time buffer the vibration transmitted from the cue head when hitting the ball hard, increasing the comfort of the shot. On the other hand, since the billiard cue in this embodiment is composed of carbon fiber blocks 0 and wooden blocks 1, the hollow structure formed by the L-shaped carbon fiber blocks 0 with a 60° angle amplifies the crisp sound when hitting the ball, improving the interactivity and enjoyment of billiards and enhancing the fun of competitive sports.
[0057] In another embodiment of this utility model, the carbon fiber block 0 is two isosceles trapezoidal blocks with the same shape, area and size. A through groove is opened at the midpoint of the lower base (longer side) of one trapezoidal carbon fiber block 0 and a through groove is opened at the midpoint of the upper base (shorter side) of the other trapezoidal carbon fiber block 0, forming a set. The two through grooves can be interlocked to form a cross shape. The wooden block 1 is set at the opening of each set of carbon fiber blocks 0 in the cross shape, and the fan-shaped edge is attached to both sides of the cross-shaped carbon fiber blocks 0.
[0058] The manufacturing method of this embodiment can be referred to in other embodiments of this utility model for installation and manufacturing.
[0059] In any embodiment of this utility model, a prefabricated wooden block is made by processing suitable wood into strip-shaped, fan-shaped, or conical blocks, baking them to remove excess moisture, and then taking a prefabricated carbon fiber block of appropriate shape and gluing and fixing the carbon fiber block to the wooden block to complete the production of the wood-carbon fiber billiard cue.
[0060] After the billiard cue of this invention is manufactured, its outer surface is painted, transferred, and glued to increase the overall aesthetics and grip comfort of the cue. Since there is no need to re-straighten the cue, processing steps are saved, thereby reducing production costs and saving manpower and resources.
[0061] The wood-coated carbon fiber billiard cue of this invention has lower requirements for wood than that of a solid wood cue, allowing for a wider selection of wood types. It can also utilize scrap wood (as long as the length is guaranteed) for processing, improving wood utilization and saving energy and being environmentally friendly. Therefore, it can reduce the production cost of the billiard cue while ensuring its quality. At the same time, it combines the advantages of carbon fiber and wood blocks, reducing the deformation of the wood-coated carbon fiber cue. In addition, the production quality of wood block 1 can be inspected during the manufacturing process, reducing rework and saving manpower and resources.
[0062] The wood-carbon fiber billiard cue of this utility model, by adding a carbon fiber block 0 as the inner core of the billiard cue, can form a stable support for the fan-shaped wood block 1. At the same time, it can correct the deformation and internal cracking of the billiard cue caused by factors such as hand sweat and environmental humidity, and reduce the impact of insects on the billiard cue to a certain extent. In this way, it avoids the impact of twisting and deformation of pure wood billiard cues on the accuracy of the shot, reduces maintenance costs, and increases the service life of the billiard cue.
[0063] Furthermore, since this utility model utilizes a combination of carbon fiber block 0 and wood block 1 to produce a billiard cue, it leverages the inherent waterproof, sweatproof, deformation-resistant, heat-resistant, and cold-resistant properties of carbon fiber material while retaining the texture of wood. This improves the manufacturing precision of the billiard cue while reducing production costs. Compared to a pure wooden cue, it exhibits less deformation; compared to a pure carbon fiber cue, it is heavier, easier to grip, and cheaper. This reduces the production and manufacturing costs of the billiard cue, saving manpower and resources. Simultaneously, the use of carbon fiber reduces the bending deformation of the wood, thereby minimizing deformation during use and ensuring the accuracy of the shot.
[0064] Meanwhile, due to the uniform and delicate structure of carbon fiber, it has high vibration damping and strong rigidity. It can also improve the rebound of the ball when it hits, reduce the impact of vibration on the trajectory of the billiard ball, and absorb impact better, making billiards more accurate and reducing the impact of equipment on the fairness of competitive sports.
[0065] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
