Abstract

To provide a billiard cue case which is both lightweight and strong, and which is easy to take out and clean, and can be stored and transported with the cue still connected. [Solution] The inner case 1 is made of lightweight and sufficiently strong materials such as polystyrene foam, aluminum, plastic, and carbon fiber, or a combination of these, and has a two-part structure for a butt storage section 3 and a shaft storage section. The combination of an opening and closing structure with the long side as the axis and an upper opening makes it easy to store and remove cues and clean the inside. In addition, a partition is provided to prevent cues from touching each other, improving protective performance. Furthermore, the size can be adjusted to store 2 to 4 butts and 3 to 5 shafts, and the case can also be stored with the cues connected, achieving convenience and protective performance not found in conventional products.

Description

[Technical field]

[0001] This invention relates to a new type of cue case for safely storing and transporting billiard cues, particularly the structure of the inner case. The inner case is made of a lightweight material with sufficient strength, and is designed to be applicable to soft cases, hard cases, and box-shaped cases. [Background technology]

[0002] Traditionally, billiard cue cases fall into three categories: 1. Soft case They are characterized by their lightweight design, using flexible materials such as nylon, artificial leather, and genuine leather. This makes them easy to handle and less of a burden to carry. In addition, they often have a zipper opening mechanism that uses the long side as an axis, making it relatively easy to put in and take out cues. However, because of their flexibility, the case as a whole is not rigid, so the cues inside may be damaged if they are subjected to pressure or impact from the outside. In particular, they cannot provide sufficient protection in situations where items collide with each other or are compressed during transportation. 2. Hard case The most common structure is a cylindrical structure made of hard materials such as plastic or aluminum, which is then covered with nylon, artificial leather, or genuine leather. This type of case is highly resistant to external impacts and provides excellent protection for the cue inside. On the other hand, the high strength of the hard material means that the weight of the case itself increases, which can be a burden when carrying it around, making it unsuitable for long-term travel or carrying. In addition, the internal structure of the case is cylindrical and airtight, making it difficult to clean the chalk powder and dust that accumulates at the bottom, so the inside easily becomes dirty after long-term use. 3. Box case Box-shaped cases made of hard materials such as aluminum, wood, and plastic feature a rectangular parallelepiped design that can be opened and closed along the long side, and are strong enough to withstand strong external impacts. However, this type of case has several issues. First, the shape of the inside of the case is designed to store the cue in a disassembled state, so it cannot be stored in an assembled state or transported easily. Therefore, when moving around with the cue connected, mainly for games, it is necessary to repeatedly disassemble and reassemble, which is inconvenient. In addition, the weight of the material increases in proportion to the strength, which can be a burden when transporting for long periods of time. Summary of the Invention [Problem to be solved by the invention]

[0003] Conventional cue cases have the following problems: 1. Lightweight yet strong Soft cases are lightweight but lack strength, while hard cases and box-shaped cases are strong but can be heavy. 2. Convenience of storage and retrieval Box-shaped cases can only store cues in a disassembled state, and cannot accommodate easy transportation in an assembled state. In addition, soft cases do not have a strong internal structure, making it difficult to safely store and remove cues. 3. Lack of cleanability Hard cases and box-shaped cases generally have a structure that makes it difficult to clean the inside, and chalk powder and dust tend to accumulate. [Means for solving the problem]

[0004] In order to solve these problems, the present invention proposes an inner case having the following features: 1. Dimensions and materials The inner case is designed to accommodate the standard dimensions of bats and shafts. Specifically, it can accommodate bats with a length of approximately 74 cm and a diameter of approximately 35 mm at the thickest part, and shafts with a length of approximately 74 cm (approximately 77 cm for the longest one) and a diameter of approximately 25 mm at the thickest part. The case is made of a lightweight and sufficiently strong material such as polystyrene foam, aluminum, plastic, or carbon fiber, or a combination of these materials. 2. Slot Design The bat storage slots are approximately 35 mm in diameter, and the shaft storage slots are approximately 25 mm in diameter, designed to prevent items from touching each other. In addition, there are approximately 7 mm dividers between the slots to prevent damage from vibrations and impacts during transport. 3. Two types of ejection mechanism In addition to being able to open and close the entire case along the long side, by opening the top, it is possible to store disassembled cues as well as easily transport them assembled, providing the convenience of being able to quickly take them out during games and practice. 4. Improved cleaning The case can be separated into two halves, making it easy to clean the inside. Accumulated chalk powder and dust can be easily removed, and the pen can be kept clean even after long periods of use. 5. Versatility This inner case is primarily intended to be added as an internal mechanism for soft cases, but can also be applied to hard cases or box-shaped cases with opening and closing mechanisms, and is designed to improve the performance of conventional cases. Effect of the Invention

[0005] ● Combining light weight and strength, it reduces the burden of transporting the cue and reduces the risk of damage. ● Bats and shafts can be safely stored in standard dimensions, allowing multiple clubs to be organized efficiently. ● It can be stored and taken out in both disassembled and assembled states, improving convenience during matches and practice. ● The easy-to-clean design improves maintenance even when used over long periods of time. ● Versatile enough to be used with soft cases, hard cases, and box-shaped cases.

EXAMPLES

[0008] Hereinafter, the embodiments will be described with reference to the accompanying drawings. Reference numeral 1 denotes the main body of the inner case (bat storage side) of the present invention, which is made of a lightweight and strong material such as polystyrene foam, plastic, carbon fiber, or aluminum. This main body is provided with an upper opening 2 for removing the bat, which allows the stored bat to be quickly removed without opening and closing the entire case. In addition, a slot portion (3) for safely storing the bat is arranged inside the case, which provides a structure in which the bats are protected from contact with each other. Reference numeral 4 denotes the main body of the inner case (shaft storage side) of this invention. This is also made of the same material as the bat storage side, and has an upper opening 5 for removing the shaft. By using this opening, the shaft can be efficiently taken in and out when disassembled or assembled. The shaft storage section has slots (6) for storing shafts individually, each of which has an independent hollow structure. Dividers made of the same material are installed between the slots to prevent contact between stored items and to protect the stored items from vibration and impact during transport. The entire inner case is designed to be opened and closed along its long side, and when used with a hard case or box-shaped case (9), a hinge-type fastener (10) is used to connect the long side. This opening and closing structure makes it easy to clean the inside by opening the entire case, improving the maintenance of stored items. Even if a hinge-type fastener is not used, it can be opened and closed along its long side by combining it with the soft case body (7) placed on the outside of the case. The inner case of this invention is designed to store 2-4 bats and 3-5 shafts, and the illustrated embodiment is intended to store 3 bats and 4 shafts. The size of the case is approximately 840 mm in length, 140 mm in width, and 45 mm in height on the bat storage side and 35 mm in height on the shaft storage side, designed to correspond to the standard dimensions of billiard cues. The combination of the top opening (2, 5) and the long side shaft opening and closing structure allows the bat and shaft to be efficiently inserted and removed without opening the entire case, while the inside of the case can be easily opened completely for cleaning and maintenance when necessary. This design allows players to use their cues quickly and conveniently during games and practice. The inner case of this invention can be used as the internal structure of the soft case body (7) and can also be used as an outer case or a box-shaped case (9). It can be sold as a standalone product, or it can be commercialized through technology transfer or licensing to other companies, and has the flexibility to be implemented in a variety of forms.
