Description

Technology Field

[0001] The present invention relates to a billiards chalk case that, unlike conventional chalk cases with complex separate lifting structures, allows for efficient chalk height adjustment using a chalk case with a simple structure based on a fixing screw and a wrench, and also allows the wrench to be stored separately inside the chalk case, thereby achieving an aesthetic appearance of the chalk case while improving its convenience and efficiency of use. Background Technology

[0002] Generally, billiards is a sport designed to determine a winner and loser within established rules by striking multiple billiard balls arranged on a square table using a long, stick-shaped cue.

[0003] In billiards, a tap formed from compressed leather material is generally installed at the tip of the cue to increase friction and rebound force. Since a slippery tip of the tap makes it easy to miss shots, chalk, a solid powder, is applied to the tap to prevent this.

[0004] Chalk is generally widely manufactured by mixing ceramic powder with pigments and adhesives and compression molding it into a cubic shape. Recently, chalk cases have been used to prevent such chalk from breaking due to impact, to improve grip, and to prevent chalk powder from adhering to and contaminating the user's body.

[0005] However, most conventional choke cases simply have the function of storing choke, and such conventional choke cases have a problem in that they are very inconvenient to use when the height of the case drops below the height of the choke as the choke is consumed.

[0006] To solve this, Patent Document 1 proposed a billiards chalk case that provides a separate support plate to support the chalk inside the chalk case and adjusts the height of the chalk by raising and lowering the support plate itself.

[0007] However, the conventional technology described above has the problem that the installation structure of the support plate for lifting and lowering inside the choke case and the operating structure for the lifting operation are not only very complex, but also that the lifting operation is not performed properly due to this complex structure or the efficiency of use is significantly reduced due to a low failure rate.

[0030] FIG. 1 is a perspective view of a billiard chalk case according to the present invention, FIG. 2 is a perspective view showing an open state of a billiard chalk case according to the present invention, FIG. 3 is an exploded perspective view of a billiard chalk case according to the present invention, and FIG. 4 is a cross-sectional view showing the process of using a billiard chalk case according to the present invention.

[0031] Referring to FIGS. 1 to 4, a billiards chalk case according to the present invention comprises a chalk box (100) and a cover part (200).

[0032] The chalk box (100) accommodates a billiard chalk (C) inside and has an open top so that the upper surface of the chalk (C) is exposed to the outside. When the upper surface of the chalk (C) is consumed, the chalk (C) is spaced upward from the inner bottom surface of the chalk box (100) at a predetermined distance so that the upper surface of the chalk (C) is additionally exposed. A fixing means (110) is provided at one end of the chalk box (100) to fix the spaced-out and exposed state of the chalk (C).

[0033] The above fixing means (110) is configured to include a fixing screw (111) and a separately provided wrench (112). More specifically, the fixing screw (111) is inserted and coupled by penetrating one side end of the choke box (100) and is inserted into the inside of the choke box (100) by rotation. The wrench (112) is selectively connected to or disconnected from the fixing screw (111), and when connected to the fixing screw (111), the fixing screw (111) is rotated to be inserted into the inside of the choke box (100).

[0034] Accordingly, when the upper surface of the choke (C) is consumed, the choke (C) is spaced upward by a predetermined distance from the inner bottom surface of the choke box (100), the wrench (112) is fastened to the fixing screw (111), and the fixing screw (111) is rotated through the wrench (112) to be inserted into the inside of the choke box (100), and the inserted fixing screw (111) comes into contact with the choke (C) in the state of being spaced upward by a predetermined distance, thereby fixing the spaced and exposed state of the choke (C).

[0035] Meanwhile, when the retraction operation of the fixing screw (111) is implemented by rotating the wrench (112) in one direction, the fixing screw (111) is withdrawn again when the wrench (112) is rotated in the opposite direction.

[0036] In addition, the above chalk box (100) can generally be made in a widely used rectangular shape, but is not necessarily limited thereto, and can be manufactured in various shapes such as a circle or other polygons corresponding to the shape of the chalk.

[0037] The above cover portion (200) finishes the top of the choke box (100) and is attached to and detached from the choke box (100) via a magnet.

[0038] More specifically, a first magnet (M1) is provided on the contact surface with the upper side cover portion (200) of the choke box (100), and a second magnet (M2) that is detachably attached to the first magnet (M1) is provided on the contact surface with the lower side cover portion (200) of the choke box (100), so that the choke box (100) and the cover portion (200) are detachably attached via the first magnet (M1) and the second magnet (M2).

[0039] Here, the first magnet (M1) and the second magnet (M2) are provided as magnets of mutually detachable polarity, but for either one, a metal that is detachable from the magnet may be used instead of the magnet.

[0040] In addition, a wrench receiving groove (210) for receiving a wrench (112) of the fixing means (110) is formed at one end of the cover portion (200), and more specifically, a wrench receiving groove (210) formed in a shape corresponding to the shape of the wrench (112) is formed at one end of the contact surface with the lower side choke box (100) of the cover portion (200).

[0041] Meanwhile, a third magnet (M3) that is detachably attached to the wrench (112) is provided inside the wrench receiving groove (210), so that the wrench (112) is detachably attached to the wrench receiving groove (210) via the magnet.

[0042] That is, as described above, when the upper surface of the chalk (C) for billiards is consumed due to use, the chalk (C) inside the chalk case is separated upward from the inner bottom surface of the chalk box (100) by a predetermined distance to further expose the upper surface of the chalk (C), and then the separated and exposed state can be fixed using a fixing screw (111) and a wrench (112). This allows for efficient chalk (C) height adjustment operation to be performed with a simple structure, unlike conventional chalk cases that use a complex separate lifting structure. Furthermore, by allowing the wrench (112) to be stored separately inside the chalk case, the chalk case can be made aesthetically pleasing in appearance while improving the convenience and efficiency of use.

[0043] The present invention is not limited to the embodiments described above and has a diverse scope of application. Furthermore, it is understood that anyone with ordinary knowledge in the field to which the present invention pertains can make various modifications without departing from the essence of the invention as claimed in the claims.
