Additionally, referring to Figures 1 and 3, the main bobbin includes an insertion portion 2 extending downward from the rotation axis.

Additionally, referring to FIGS. 1, 3, and 4, the bobbin includes a protrusion 3 that protrudes outward from the upper outer surface of the insertion portion 2. A plurality of protrusions 3 may be provided along the upper circumferential direction of the insertion portion 2. Additionally, the protrusion 3 may have various cross-sectional shapes. For example, it may have a square-shaped cross-section (see FIG. 4) or a cross-section shaped like at least a portion of a circle (see FIG. 5(a)). Additionally, the thickness of the protrusion 3 in the inner and outer directions may decrease as it moves downward.

Additionally, referring to FIGS. 1, 3, and 4, the bobbin may include a handle portion 5 in which an opening is formed upward and the insertion portion 2 is inserted into the opening. The portion of the insertion portion 2 positioned below the portion where the protrusion 3 is formed is inserted into the opening. Additionally, the insertion portion 2 is inserted into the opening so that relative rotation with respect to the handle portion 5 is possible.

Additionally, referring to Figures 3 and 4, the insertion part 2 may be fastened to the handle part 5 to prevent upward removal from the opening. For example, the handle portion 5 may be formed with a band-shaped fastening protrusion 42 that protrudes inward from the inner surface of the opening.

Additionally, referring to Figures 3 and 4, a fastening part 7 may be formed in the lower part of the insertion part 2. The fastening part 7 may include an insertion section 74 located inside the fastening protrusion 42. In addition, the main bobbin is located below the fastening protrusion 42 and may include a fastening section 73 having an outer diameter larger than the inner diameter of the fastening protrusion 42 so as to be caught upwardly by the fastening protrusion 42. The outer shape of at least a portion of the fastening section 73 (maximum outer diameter of the fastening section 73) may be larger than the inner diameter of the fastening protrusion 42. Accordingly, upward removal of the fastening section portion 73 can be prevented.

Additionally, a recessed portion 71 that is recessed from the lower surface to the upper side and is open in the radial direction may be formed in the fastening portion 7. Additionally, the fastening portion 7 may be made of a material containing elasticity to enable elastic deformation in which the inner diameter of the recessed portion 71 is reduced in response to external force. For example, the fastening part 7 may be made of a material containing plastic.

Accordingly, when the fastening portion 7 is inserted into the opening of the insertion portion 2, the inner diameter of the recessed portion 71 is elastically deformed and the fastening section 73 is a portion where the fastening protrusion 42 of the opening is formed. It may be located on the lower side of the part where the fastening protrusion 42 is formed, and the inner diameter of the lower side of the part where the fastening protrusion 42 of the opening is formed is larger than the maximum outer diameter of the fastening section 73, so the elasticity is restored. Thus, the fastening section 73 may have an outer diameter larger than the inner diameter of the portion where the fastening protrusion 42 is formed, and may be caught upwardly by the fastening protrusion 42.

Additionally, the fastening section 73 of the fastening portion 7 may have a wedge shape whose diameter decreases as it moves downward. Accordingly, when the insertion portion 2 is inserted into the opening for assembling the main reel, the fastening section 73 passes through the portion where the fastening protrusion 42 is formed due to its wedge shape and is easily elastically deformed to form the fastening protrusion. It may pass through (42) and be located on the lower side of the fastening protrusion (42). For this purpose, the outer diameter of the upper end of the fastening section 73 is larger than the inner diameter of the portion where the fastening protrusion 42 of the opening is formed (inner diameter of the fastening protrusion 42), but the outer diameter of the lower end of the fastening section 73 is larger than the inner diameter of the portion where the fastening protrusion 42 of the opening is formed. It is preferable that the inner diameter of the protrusion 42 is smaller, and that the fastening section 73 has a wedge shape whose diameter decreases as it goes downward.

also. To facilitate elastic deformation of the fastening portion 7, the upper end 711 of the recessed portion 71 may have a larger inner diameter than other portions. Additionally, referring to FIG. 3, a long groove (reference numeral not assigned) may be formed on the outer surface of the insertion portion 2. Accordingly, the elastic force of the insertion portion 2 may be greater than in the case where the long groove is not formed.

Additionally, referring to FIG. 3, the insertion portion 2 is inserted into the opening to enable relative rotation with respect to the handle portion 4. For example, at least a part of the insertion part 2 (for example, the part located above the fastening part 7 of the insertion part 2, the fastening section 73) may be smaller than the inner diameter of the opening, Accordingly, the insertion part 2 can rotate relative to the handle part 4 when an external force is applied.

Therefore, referring to FIGS. 1 and 3, when the user holds the handle portion 4 and rotates the main body 1 with respect to the handle portion 4, the insertion portion 2 moves with respect to the handle portion 4. The handle portion 4 and the insertion portion 2 may be rotated while rotating relative to the rotation axis in the vertical direction. Also, for reference, as described above, the main body 1 may include an auxiliary handle 13, where the user holds the handle portion 4 with one hand and holds the auxiliary handle 13 with the other hand. The main body (1) can be easily rotated by holding and using the auxiliary handle (13) to apply an external force to the main body (1) and the insertion part (2) to rotate about the rotation axis of the main body (1), Accordingly, winding or unwinding of the kite string can be performed.

Additionally, referring to FIGS. 1, 3, and 4, this bobbin may include a stopper (5). The stopper 5 may have a through hole formed in the longitudinal direction. In addition, it is provided to surround the upper part of the handle part 4 so that the upper part of the handle part 4 is located within the through hole, and is provided to be movable up and down with respect to the upper part of the insertion part 2 and the upper part of the handle part 4. It can be. Additionally, an engaging portion 51 capable of engaging with the protruding portion 3 may be formed on the top of the stopper 5. For example, when the protrusion 3 has a square cross-section (see FIG. 4), the engaging portion 51 has the same cross-section as the protrusion 3 from the part where the upper part of the insertion portion 2 is inserted and extends to the outside. It may be formed to be recessed (formed to have a square cross-section), and one or more protrusions 3 may be formed to correspond to each other. In addition, when the protrusion 3 has a cross section shaped like at least a portion of a circle (see (a) in FIG. 5), the engaging portion 51 is formed by protruding the protrusion 3 from the portion where the upper part of the insertion portion 2 is inserted. ) and can be formed to be depressed outward with the same cross section.

In addition, the stopper 5 may be provided to be movable up and down with respect to the upper part of the insertion part 2 and the upper part of the handle part 4, but may be provided not to rotate with respect to the handle part 4. For example, at the top of the handle portion 4, a portion of the outer surface in the circumferential direction may be cut in the vertical direction, and the stopper 5 has a through hole with a circular inner cross section, and the upper portion of the handle portion 4 It can wrap around the upper part of the handle portion (4) so that it is located in the through hole. Accordingly, the stopper 5 can be provided so that it can move up and down with respect to the upper part of the handle part 4 but cannot rotate with respect to the handle part 4.

In addition, referring to FIG. 3, as described above, the thickness of the protrusion 3 in the inner and outer directions may decrease as it moves downward. In this case, the engaging portion 51 may be provided with an inner diameter that decreases as it moves downward. .

In summary, referring to Figures 3 (a) and 4, the stopper (5) is provided to surround the upper part of the handle part (4) so that it does not rotate with respect to the handle part (4), and (b) in Figure 3 Referring to this, when moving upward, it surrounds at least a portion of the upper part of the insertion portion 2 (the portion where the protrusion 3 is formed) and engages with the protrusion 3 to prevent relative rotation with respect to the handle portion 4 of the main body 1. You can. For reference, referring to (a) of FIG. 3, the stopper 5 is provided to surround the handle portion 4 before moving upward, and is provided at a portion of the upper part of the insertion portion 2 (i.e., the lower portion of the protrusion 3). It can also be provided to surround the . However, even in this case, a part of the upper part of the insertion part 2 (lower part of the protruding part 3) can be wrapped so that the rotation of the main body 1 is not interfered with by the stopper 4. For example, the protrusion 3 may have a shape in which the cross-sectional area (cross-sectional area in the horizontal direction) decreases as it goes downward (a shape in which the thickness in the inner and outer directions decreases as it goes downward), and the engaging portion 51 also has a lower cross-sectional area. It may have a shape where the cross-sectional area decreases as you move towards it. In this case, the inner diameter of the upper part of the engaging portion 51 is set larger than the protruding amount of the lower part of the protruding portion 3, so that even if the stopper 5 wraps around the lower part of the protruding portion 4 before the upward movement of the stopper 5, the engaging portion 51 is not engaged. Since the portion 51 and the protrusion 3 are not engaged, interference may not occur in the rotation of the main body 1.

In addition, referring to FIGS. 3 and 4, the handle portion 4 has an outer diameter of the lower portion that is the inner diameter of the through hole of the stopper 5 so that the stopper 5 is restricted from moving to the lower side of the upper portion of the handle portion 4. It can be set larger. Accordingly, a limiting protrusion 41 may be formed at the lower portion of the handle portion 4, which protrudes outward compared to the upper portion of the handle portion 4 to limit the movement of the stopper 5 to the lower portion of the handle portion 4. In addition, the stopper 5 is restricted from moving to the lower side of the upper part of the handle part 4 by the limiting jaw 41, so that it is limited to the upper part of the handle part 4 and the upper part of the insertion part 2. can be moved about.

Additionally, a limiting member 6 protruding outward from the outer peripheral surface may be provided at the lower end of the rotating shaft 11. The limiting member 6 may be provided in the form of a band-shaped disk surrounding the lower end of the rotating shaft, and may restrict the stopper 5 from moving above the portion where the protrusion 3 is formed. For this purpose, the outer diameter of the limiting member 6 is preferably larger than the maximum inner diameter (inner diameter of the uppermost end) of the stopper 5.

Additionally, according to the present application, the main body 1, the insertion portion 2, and the protruding portion 3 may be formed as one piece. Accordingly, this bobbin can be easily assembled by inserting the insertion portion 2, which is formed integrally with the main body 1 and the protrusion 3, into the opening of the handle 4 combined with the stopper 5. . Accordingly, manufacturing may be easy.
