[0021] FIGS. 1 to 3 illustrate a cheering tool according to a first embodiment of the present invention. Specifically, FIG. 1 illustrates an assembled perspective view of a cheering tool according to a first embodiment of the present invention, FIG. 2 illustrates a cross-sectional view of a cheering tool according to a first embodiment of the present invention, and FIG. 3 illustrates a state of use of a cheering tool according to a first embodiment of the present invention.

[0022] A cheering tool (1) according to one embodiment of the present invention includes a first stick (100) and a second stick (200).

[0023] The first stick (100) is a hollow cylindrical shape having a first thickness (t1), a first outer diameter (D1), and a first height (h1), and the second stick (200) is a hollow cylindrical shape having a second thickness (t2), a second outer diameter (D2), and a second height (h2). When the user holds the first stick (100) and the second stick (200) in their hand, the first stick (100) and the second stick (200) collide, causing resonance to occur in the first and second sticks (100, 200), and sound to spread out through the open end, thereby enabling cheering.

[0024] In this embodiment, the first stick (100) includes both ends (120, 130) in the longitudinal direction and a first side portion (110) formed with a first thickness (t1) between the two ends, both ends (120, 130) are open, and a first protrusion (135) protruding inwardly to the radius of the first stick (100) is formed on one end (130), and no first protrusion is formed on the other end (120). The outer surface of the first side portion (110) is used as a printed surface (101).

[0025] The second stick (200) includes both ends (220, 230) in the longitudinal direction similar to the first stick (100) and a second side portion (210) formed with a second thickness between the two ends (220, 230). Both ends (120, 130) of the second stick (200) are also open, and a second protrusion (235) protruding inwardly toward the second stick (200) is formed at one end (230). The outer surface of the second side portion (210) is used as a printed surface (201).

[0026] The first stick (100) and the second stick (200) generally have a similar hollow cylindrical structure, but the inner diameter (d1) of the first side portion (110) of the first stick (100) is larger than the outer diameter (D2) of the second side portion (210) of the second stick (200), so that the second stick (200) can be inserted into the hollow (105) of the first stick (100). That is, in this invention, the fact that the inner diameter (d1) of the first side portion (110) of the first stick (100) is larger than the outer diameter (D2) of the second side portion (210) of the second stick (200) means that the second side portion (210) of the second stick (200) can enter into the inside of the first side portion (110) of the first stick (100).

[0027] At this time, the gap (G) between the first side portion (110) of the first stick (100) and the side portion (210) of the second stick (200) can be formed to be 1 mm or less.

[0028] Meanwhile, a first protrusion (135) is formed on one end (130) of the first stick (100). The first protrusion (135) is an annular protrusion formed by curling the end of the first side part (110), and the height (h3) in the inner direction of the first protrusion (135) is greater than the difference between the inner diameter (d1) of the first side part (110) of the first stick (100) and the outer diameter (D2) of the second side part (210) of the second stick (200).

[0029] Accordingly, when the second stick (200) is inserted into the hollow (105) of the first stick (100), the second stick (200) is caught on the first protrusion (135), so that the second stick (200) can be maintained in a state of being received inside the first stick (100). That is, the first protrusion (135) acts as a stopper. In addition, the first protrusion (135) may also act as a structural part that complements the rigidity of the first stick (100).

[0030] Meanwhile, the first height (h1) of the first stick (100) and the second height (h2) of the second stick (200) are the same, and when the second stick (200) enters the inside of the first stick (100), the second stick (200) protrudes outward from the first stick (100) by the height-direction length of the first protrusion (135), and when separating the second stick (200), the user can grasp the protruding part and pull the second stick (200) out from the first stick (100). Therefore, it is easy to separate the second stick (200) from the first stick (100) again after inserting the second stick (200) into the first stick (100).

[0031] A second protrusion (235) is also formed on one end (230) of the second stick (200), and the second protrusion (235) is an annular protrusion formed by curling the end of the second side part (210) similarly to the first protrusion (135). The second protrusion (235) protrudes inward, and its height may be the same as that of the first protrusion (135).

[0032] The second stick (200) can function as a structural part that complements the rigidity of the second stick (200) similarly to the first protrusion (135) by including a second protrusion (235), and can also function as a handle for gripping the second stick (200) when the second stick (200) is inserted into the first stick (100).

[0033] In the first embodiment, the first stick (100) and the second stick (200) may be formed of paper material and may be formed with the same thickness (t1=t2), but are not limited thereto. The first thickness (t1) and the second thickness (t2) may be between 1 and 2 mm. If the thickness (t1, t2) is less than 1 mm, it is difficult to maintain a hollow cylindrical shape with paper material, and if it exceeds 2 mm, a dull sound is produced, making it unsuitable as a cheering tool.

[0034] In the first embodiment, the first height (h1) and the second height (h2) may be between 30 and 40 cm, and the ratio of the first outer diameter to the first height (h1) and the ratio of the second outer diameter (D2) to the second height (h2) may be between 1:6 and 1:8. For example, the first height (h1) and the second height (h2) may be 35 cm, the first outer diameter (D1) may be 5 cm, and the second outer diameter (D2) may be 4.8 cm.

[0035] When the ratio of the first outer diameter to the first height (h1) is less than 1:6, it is difficult for the user to hold the first stick (100) with one hand, and when it is greater than 1:8, the resonance is insufficient.

[0036] Table 1 below shows the results of measuring the loudness of the sound when the pitch was varied.

[0037] Specifications (thickness, outer diameter, height) Unit: mm decibels (db) Comparative Example 1 1, 48, 250 62~84 Comparative Example 2 2, 50, 650 64~93 Invention Example 1 1, 50, 350 64~90 2 in invention 2, 50, 340 64~90

[0038] As shown in Table 1, when the thickness and outer diameter were at an equivalent level, in the case of Comparative Example 1, which had a shorter height, no loud sound was produced, and even if the height increased, no loud sound was produced in proportion to the increase in height.

[0039] In addition, Table 2 tests the frequency of sound generated while changing the pitch and indicates the highest frequency band in the measured sound.

[0040] Specifications (Thickness, Outer Diameter, Height) Unit: mm highest measured frequency (Hz) Comparative Example 1 1, 48, 250 603 Comparative Example 2 1, 48, 270 568 Comparative Example 3 1, 48, 290 535 Invention Example 1 1, 48, 310 491 Invention Example 2 1, 48, 330 462 Invention Example 3 1, 48, 350 441 Invention Example 4 1, 48, 370 427 Invention Example 5 1, 48, 390 404 Comparative Example 4 1, 48, 410 388 Comparative Example 5 1, 48, 430 376 Comparative Example 6 1, 48. 450 361

[0041] As shown in Table 2, as the height increases, the measured frequency of the sound decreases. For the sound to travel a long distance, approximately 440 Hz, or the 'A' note of an oboe, is desirable.

[0042] Accordingly, in the present invention, the first and second heights (h1, h2) of the first and second sticks (100, 200) preferably satisfy a range of 30 to 40 cm so that sound is produced sufficiently, is easy to carry, and produces a loud sound in the 400 Hz range.

[0043] In the case of the cheering tool (1) of the first embodiment, the durability of each stick (100, 200) is secured through the protrusions (135, 235), and the second stick (200) can be inserted into the first stick (100) to facilitate carrying and storage, and it is also possible to print advertisements of the cheering team through the printing surfaces (101, 201) of the first and second sticks (100, 200). In addition, the protrusions (135, 235) not only adjust the connection position of the first and second sticks (100, 200), but also make insertion and release easier.

[0044] In addition, in the first embodiment, the cheering tool (1) is formed from paper material and can be recycled after use, thereby reducing environmental pollution. Also, since it is formed from paper material with a certain thickness, it is not discarded after one use but can be used multiple times.

[0045] FIG. 4 shows a cross-sectional view of a modified example of the first embodiment of the present invention.

[0046] In the structure of the first embodiment, the first stick (100) and the second stick (200) may be formed of synthetic resin rather than paper material. That is, the first and second sticks (100, 200) may be formed of synthetic resins such as polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and polyskirene (PS). Therefore, in addition to the structure in which the first and second protrusions (135, 235) are rolled as in the first embodiment of FIGS. 1 to 3, it is also possible to have other shapes, and such a structure is illustrated in FIG. 4.

[0047] As shown in FIG. 4(a), the first protrusion (135') may have a folded structure in which one end (130) is bent at a right angle, in which case the end surface (135a) of the first protrusion (135') may face in a direction perpendicular to the height direction. Alternatively, as shown in FIG. 4(b), the first protrusion (135'') may have a folded structure in which one end (130) is folded 180°, in which case the end surface (135a) of the first protrusion (135'') faces the opposite end (120).

[0048] Additionally, as shown in FIG. 4(c), the first protrusion (135) may protrude slightly inward rather than at the end of the end (130). That is, a portion (130a) may be located outside the first protrusion (135) on the end (130), and the end surface (135a) of the first protrusion (135) may face in a direction perpendicular to the height direction.

[0049] FIG. 5 shows a cross-sectional view of a cheering tool (1) of the second embodiment of the present invention.

[0050] In the case of the cheering tool (1) of the second embodiment, it includes first and second sticks (100, 200) similar to the cheering tool (1) of the first embodiment, the first stick (100) is a hollow cylindrical shape having a first thickness (t1), a first outer diameter, and a first height (h1), and the second stick (200) is a hollow cylindrical shape having a second thickness (t2), a second outer diameter, and a second height (h2). Since it is similar to the first embodiment overall, the explanation will focus on the differences.

[0051] In the second embodiment, similar to the first embodiment, the second stick (200) is configured to be inserted into the inner side of the first stick (100). However, in the case of the second embodiment, unlike the first embodiment, a second protrusion (225, 235) is provided at each end (220, 230) of the second stick (200). Therefore, not only can the second stick (200) having a smaller outer diameter be structurally reinforced, but a single second protrusion (225, 235) is located on the outside of the first stick (100) regardless of the direction of the second stick (200) inserted into the first stick (100), making it easy to separate the second stick (200).

[0052] In the second embodiment, the second height (h2) of the second stick (200) may be greater than the first height (h1) of the first stick (100), and accordingly, when the second stick (200) is inserted into the first stick (100), the length of the second stick (200) protruding outward is longer, making it more advantageous to grasp the second protrusion (225, 235).

[0053] FIG. 6 shows a cross-sectional view of a cheering tool (1) of the third embodiment of the present invention.

[0054] The third embodiment also includes a first stick (100) and a second stick (200) similar to the first embodiment, and has a structure in which the second stick (200) is inserted into the inside of the first stick (100). In the third embodiment, the description of parts identical to the first embodiment is omitted, and the description focuses on the differences.

[0055] In the third embodiment, the first side portion (110) of the first stick (100) includes a first through hole (111) at a position adjacent to the first protrusion (135), and the second side portion (210) of the second stick (200) includes a second through hole (211) at a position adjacent to the second protrusion (235).

[0056] The cheering tool (1) of the third embodiment further includes a connecting member (300) made of a flexible material, such as a string, that connects the first stick (100) and the second stick (200), and the connecting member (300) passes through the first through hole (111) and the second through hole (211) to connect the first stick (100) and the second stick (200).

[0057] The above connecting member (300) includes a first anti-slip portion (310) in which the end of the connecting member (300) passes through the first through hole (111) and is disposed inside the first stick (100). The first anti-slip portion (310) may protrude from the first side portion (110) to a certain height (h4). At this time, instead of the first protrusion (135), the first anti-slip portion (310) may serve as a stopper that restricts the movement of the second stick (200) in the height direction. At this time, the height (h4) of the first anti-slip portion (310) may be greater than the difference between the inner diameter (d1) of the first stick (100) and the outer diameter (D2) of the second stick (200).

[0058] The first anti-slip part (310) may be a separate component different from the connecting member (300), but may also be a structure formed from the connecting member (300), for example, a knot.

[0059] Likewise, the connecting member (300) includes a second anti-slip portion (320) in which the end of the connecting member (300) passes through the second through hole (211) and is disposed inside the second stick (200). The second anti-slip portion (320) may have the same structure as the first anti-slip portion (310), but is not limited thereto.

[0060] The connecting member (300) may have a length longer than the first height (h1) and the second height (h2), so that the second stick (200) can be inserted into the first stick (100) or the second stick (200) can be pulled out from the first stick (100) while the connecting member (300) is connected. This connecting member (300) can be used as a hanging means to hang on a user's neck or shoulder, and the first stick (100) and the second stick (200) can be connected to prevent either one from being lost.

[0061] In addition, the first stick (100) and the second stick (200) are connected so that when a user throws the first stick (100) or the second stick (200), the cheering tool (1) can be prevented from flying far away.

[0062] FIG. 7 shows a cross-sectional view of a cheering tool (1) of the fourth embodiment of the present invention.

[0063] The cheering tool (1) of the fourth embodiment includes a first stick (100) and a second stick (200), and also includes a connecting member (300) that connects the first stick (100) and the second stick (200). In the fourth embodiment, the description of parts identical to those of the first embodiment is omitted, and the description focuses on the differences.

[0064] In the fourth embodiment, at the end (130) of the first stick (100) and the end (230) of the second stick (200), instead of the first and second protrusions (135, 235) formed by molding a part of the first stick (100) or the second stick (200), the first anti-slip portion (310) and the second anti-slip portion (320) of the connecting member (300) are disposed. That is, the first anti-slip portion (310) corresponds to the first protrusion (135) of the first stick (100) of the first embodiment and operates with the same configuration to perform the role of a stopper that restricts the movement of the second stick (200) when the second stick (200) is inserted into the first stick (100).

[0065] FIG. 8 shows a cross-sectional view of a cheering tool (1) of the fifth embodiment of the present invention, and FIG. 9 shows a usage state diagram of a cheering tool (1) of the fifth embodiment.

[0066] The cheering tool (1) of the fifth embodiment includes a first stick (100) and a second stick (200), and also includes a connecting member (300) that connects the first stick (100) and the second stick (200). In the fifth embodiment, the description of parts identical to those of the first embodiment is omitted, and the description focuses on the differences.

[0067] In the fifth embodiment, a first surface (140) is provided at the end (130) where the first protrusion (135) of the first stick (100) is formed, and a second surface (240) is provided at the end (130) where the second protrusion (235) of the second stick (200) is formed, and the connecting member (300) connects the first surface (140) and the second surface (240). That is, the first anti-slip portion (310) of the connecting member (300) is placed on the inner side of the first surface (140), and the second anti-slip portion (320) of the connecting member (300) is placed on the inner side of the second surface (240).

[0068] In this case, in the fifth embodiment, the inner diameter (d1) and outer diameter (D1) of the first stick (100) are configured to correspond to the inner diameter (d2) and outer diameter (D2) of the second stick (100), so that the second stick (200) is not inserted into the interior of the first stick (100). However, similar to the first embodiment, the inner diameter (d1) of the first side portion (110) of the first stick (100) is larger than the outer diameter (D2) of the second side portion (210) of the second stick (200), so that the structure may be such that the second stick (200) is inserted into the interior of the first stick (100).

[0069] As shown in FIG. 9, the user can wear the connecting member (300) around their neck, hold the first stick (100) with one hand and the second stick (200) with the other hand, and then strike the first stick (100) and the second stick (200) together to produce a loud sound that spreads far.

[0070] Although the present invention has been described above with reference to embodiments, the invention is not limited thereto and can be implemented with various modifications. Explanation of the symbols
