[0027] Hereinafter, a yo-yo according to one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of the yo-yo 1, and FIG. 2 is a cross-sectional view showing the inside of the yo-yo 1. As shown in FIG. 1 and 2 comprises a shaft member 30, a pair of left and right first pivoting sections 10 that are rotatable around the shaft member 30, and a pair of left and right second pivoting sections 20 that are rotatable around the shaft member 30 and are rotatable relative to the first pivoting sections 10 on the outside of the first pivoting sections. A bearing 50 (first bearing 51) is provided around the shaft member 30 between the left and right first pivoting sections 10. Furthermore, a string member 40 is provided in the space formed between the first pivoting sections 10, and is supported by the first bearing 51 and can be wound around the first bearing 51.

[0028] The first rotating part 10 has a structure in which a disk-shaped main body 11 rotatably supported on a shaft member 30 is integrally connected to an interlocking member 12 that is axially outward of the main body 11 and has a smaller diameter than the main body 11. The main body 11 and interlocking member 12 are formed as separate members, as will be described later, and the left and right portions are further connected and integrated via the shaft member 30.

[0029] The main body 11 is configured as the thickest member. It has a circular recess 11c on its outer axial surface. A ring-shaped contact portion 11d that protrudes axially outward is provided at the bottom of the recess 11c. While the present embodiment describes the contact portion 11d as being ring-shaped, it is not limited to this shape. For example, a plurality of contact portions 11d may be provided spaced apart from each other by a predetermined distance.

[0030] Interlocking member 12 has a thin plate-like pivoting surface 12a on its axial outer surface that can pivot in conjunction with main body 11 when attached to main body 11. In other words, pivoting surface 12a faces the side of yo-yo 1. A first sheet 81 is attached to pivoting surface 12a. Interlocking member 12 also has an outer peripheral surface 12b in a direction that intersects with pivoting surface 12a, and a third sheet 83 is attached to outer peripheral surface 12b.

[0031] The second pivoting portion 20 is positioned axially outward of the interlocking member 12 and has a generally flat side surface 20a that is parallel to the pivot surface 12a. The outer peripheral edge 20b of the side surface 20a extends axially inward, with the leading edge 20c facing the abutment portion 11d. In other words, the end surface of the second pivoting portion 20 is appropriately curved to cover the side surface and end surface of the interlocking member 12. Therefore, a space SP is formed between the second pivoting portion 20 and the recessed portion 11c of the first pivoting portion 10. It is desirable that the abutment portion 11d and the leading edge 20c remain separated even when the yo-yo 1 is in use.

[0032] The second rotating part 20 is attached to the first rotating part 10 via bearings 50 (second bearings 52) arranged on both ends of the shaft member 30, and is configured to be rotatable independently of the first rotating part 10. The second rotating part 20 is made of a transparent material, and is configured so that the interlocking member 12 inside it can be seen through the second rotating part 20. As a result, although the interlocking member 12 is configured to have a different visual effect from the main body part 11, the difference in visual effect between the main body part 11 and the interlocking member 12 can be seen. Examples of visual effects include changing the color or changing the glossiness.

[0033] Furthermore, when the yo-yo 1 is viewed from the side (see FIG. 7), the pivoting surface 12a of the interlocking member 12 is visible. As described above, the first sheet 81 is provided on this pivoting surface 12a, so that the first marking i1, such as a polka dot pattern, can be seen from the outside, as will be described later. Here, because the pivoting surface 12a is positioned close to the second pivoting portion 20, the first marking i1 can be clearly seen. Furthermore, if the second pivoting portion 20 includes a lens-shaped portion, the size of the first marking i1 can be changed and viewed.

[0034] Additionally, recess 21 is formed on side surface 20a of second pivoting portion 20 at a position facing shaft member 30. This recess 21 can be used to make it easier to hold yo-yo 1. When gripping second pivoting portion 20 by firmly pressing down on either side surface 20a, abutment portion 11d can abut against leading edge 20c of second pivoting portion 20. However, when abutment portion 11d abuts leading edge 20c, second pivoting portion 20 and pivoting surface 12a of interlocking member 12 are configured to be spaced apart. This prevents contact between second pivoting portion 20 and pivoting surface 12a of interlocking member 12, preventing their movement from being impeded. It is desirable to adjust the protruding length of abutment portion 11d so that when yo-yo 1 is not being held, the distance between rotation surface 12a of interlocking member 12 and second rotation portion 20 facing rotation surface 12a is greater than the distance between the tip of abutment portion 11d and tip edge 20c. While this embodiment describes a configuration in which tip edge 20c faces abutment portion 11d, this is not a limitation. It is sufficient that a portion of second rotation portion 20 can abut against abutment portion 11d facing it, and that when they abut, second rotation portion 20 and rotation surface 12a of interlocking member 12 are separated. However, the configuration of this embodiment is desirable because it eliminates the need to provide a new protruding portion like abutment portion 11d on second rotation portion 20.

[0035] An example of how to assemble yo-yo 1 will be described below with reference to FIGS. Fig. 3 is a cross-sectional view of the yo-yo shown in Fig. 1 at an early stage of assembly. Fig. 4 is a cross-sectional view of the yo-yo shown in Fig. 1 at an intermediate stage of assembly. Fig. 5 is a perspective view of the state shown in Fig. 4. Fig. 6 is a cross-sectional view of the yo-yo shown in Fig. 1 at a final stage of assembly.

[0036] When assembling the yo-yo 1, for example, the first rotating portion 10 is assembled first, as shown in Figure 3. In this case, the nut 70 is positioned so that it fits into the central recess 11g of the main body portion 11. Meanwhile, the second bearing 52 is inserted from the inside into the inner recess 12e of the interlocking member 12, and a bearing holder 71, which secures it from the outside, is fitted into the second bearing 52. Then, a connecting member 60, such as a screw, is screwed into the screw-receiving portion 12d of the interlocking member 12 from the main body portion 11. This sandwiches and secures the second bearing 52 between the main body portion 11 and the interlocking member 12.

[0037] 4, the central boss portion 20f of the second rotating portion 20 is fitted into the inside of the second bearing 52 from the outside of the interlocking member 12. Then, a rivet 61 is driven into the central boss portion 20f from the main body portion 11 side, for example, from the outside of the bearing holding member 71, thereby connecting the first rotating portion 10 and the second rotating portion 20. As a result, the second rotating portion 20 is rotatably connected to the first rotating portion 10 via the second bearing 52.

[0038] As shown in FIG. 5, the pivoting surface 12a and the outer peripheral surface 12b of the interlocking member 12 have a first display area E1 provided with a first sheet 81 and a third sheet 83. The first information i1, which is a geometric pattern such as polka dots, is arranged in the first display area E1. The second pivoting portion 20 also has a second display area E2 provided with a second sheet 82, as described above. The second information i2, such as a specific character, is displayed on the second sheet 82. To further enhance the decorativeness of the first information i1 and the second information i2, it is preferable that the first information i1 be displayed entirely in the first display area E1 and the second information i2 be displayed in a partial area of the second display area E2. To improve the visibility of the first information i1, it is preferable that the second information i2 not be displayed in the center of the second display area E2. Furthermore, it is more preferable that the second marking i2 be displayed near the outer periphery of the second display area E2 to improve the visibility of the relative movement with the first marking i1. The second sheet 82 may be circular and cover almost the entire outer surface of the second pivoting portion 20, or may cover only a portion of it. Here, the second display area E2 is configured to have a larger area than the first display area E1, and when configured to cover almost the entire outer surface, it is made of a light-transmitting material. This improves the visibility of the first display area E1.

[0039] With the second rotating part 20 configured in this manner, when the yo-yo 1 is viewed from the front, the outer surface 12b of the interlocking member 12 can be seen, as shown in Figure 1, and when viewed from the side, the rotating surface 12a can be seen.

[0040] This assembly of first pivoting portion 10 and second pivoting portion 20 is repeated on the other side to form a pair of left and right parts. After assembling the left and right parts, as shown in Figure 6, both ends of shaft member 30, through which first bearing 51 passes, are screwed into left and right nuts 70 to assemble. In this way, yo-yo 1 as shown in Figure 1 is assembled.

[0041] Figure 7 is a side view of yo-yo 1 shown in Figure 1. Figure 8 is a side view of yo-yo 1 shown in Figure 1 with main body 11 in a rotating state. When the first rotation part 10 of the yo-yo 1 is not being rotated, the second marking i2 (a design of a character (a whale)) and the first marking i1 (polka dots) are visible simultaneously, as shown in Figure 7. On the other hand, when the first rotation part 10 is rotating (when the yo-yo 1 is being used), the first marking i1 is a concentric striped pattern rather than a polka dot pattern, as shown in Figure 8. In other words, the first marking i1 in the first display area E1 appears visually different when the interlocking member 12 is rotating and when it is stationary.

[0042] FIG. 9 is a cross-sectional view showing a modified example of the present invention. In the present invention, the second pivoting portion 20 can be configured as shown in FIG. 9. Unlike the configuration shown in FIG. 2, the second pivoting portion 20 shown in FIG. 9 does not have a substantially flat side surface 20a on the outer surface side, but rather is configured as a curved surface that bulges in the extension direction (left-right direction) of the shaft member 30. In this case, the entire side surface of the second pivoting portion 20 can function as a convex lens. This makes the first information i1 appear enlarged, and the shape of the first information i1 appears to change depending on the viewing direction. In this modified example, the second sheet 82 is configured to be provided only on a portion of the outer side of the second pivoting portion 20.

[0043] As described above, in this embodiment of the yo-yo 1, the second rotating part 20 that covers the main body 11 of the yo-yo 1 from the outside is configured so that its inside can be seen, allowing internal information to be seen in addition to information such as the picture provided on the second rotating part 20 that forms the outermost surface.

[0044] Furthermore, in this embodiment of the yo-yo 1, an interlocking member 12 is provided between the main body 11 and the second pivoting portion 20, and this interlocking member 12 can be used as an image display portion that can be seen through the second pivoting portion 20.

[0045] Furthermore, in this embodiment of yo-yo 1, second pivoting portion 20 is configured so that outer peripheral surface 12b of interlocking member 12 is visible, allowing for visual effects not only on the side surfaces of yo-yo 1 but also on the end surfaces (thicker side of yo-yo 1). Furthermore, in this embodiment of yo-yo 1, interlocking member 12 has a different visual effect from main body 11, which enhances its decorativeness. For example, the color effect can be enhanced by changing the color, and adjacent first marking i1 and second marking i2 can be decorated in different colors.

[0046] In this embodiment of yo-yo 1, interlocking member 12 can be seen through second pivoting part 20, so it is possible to superimpose information such as images on second pivoting part 20 and interlocking member 12. Furthermore, it is possible to create a visually different image when yo-yo 1 is stationary (when first pivoting part 10 is not rotating) than when it is rotating.

[0047] In this embodiment of the yo-yo 1, the second pivoting part 20 is configured in a dome shape that bulges out on the opposite side from the first pivoting part 10, making the yo-yo 1 easier to hold. Also, if the second pivoting part 20 is made of a transparent material, it can be configured as a convex lens, allowing the first information i1 on the interlocking member 12 to be viewed in an enlarged form.

[0048] In this embodiment of yo-yo 1, main body 11 and interlocking member 12 are connected by connecting member 60, making it easy to change the combination of main body 11 and interlocking member 12. Also, second bearing 52 is positioned so that it is sandwiched between main body 11 and interlocking member 12, making it possible to hold and fix second bearing 52 when interlocking member 12 is assembled. This simplifies the structure of yo-yo 1 and makes assembly easier.

[0049] In this embodiment of yo-yo 1, recess 21 is formed in side surface 20a of second pivoting portion 20, making it easier to hold yo-yo 1. Furthermore, because tip edge 20c of second pivoting portion 20 is located opposite abutment portion 11d, even when gripping second pivoting portion 20 by pressing down on either side of side surface 20a, abutment portion 11d and tip edge 20c will abut, while second pivoting portion 20 and pivoting surface 12a of interlocking member 12 will be spaced apart, maintaining a gap, preventing their movement from being impeded.

[0050] Although one embodiment of the present invention has been described above, the present invention can be modified as appropriate within the scope of its technical concept. For example, in the above embodiment, the first display area E1 is on both the rotation surface 12a of the interlocking member 12 and the outer peripheral surface 12b of the interlocking member 12, but the present invention is not limited to this and may be on either one of them.
