[0027] Hereinafter, a yo-yo, which is one aspect of the present invention, will be described with reference to the drawings. FIG. 1 is a front view of yo-yo 1, and FIG. 1 and 2 comprises an axle member 30, a pair of left and right first pivot parts 10 which are rotatable around the axle member 30, and a pair of left and right second pivot parts 20 which are rotatable around the axle member 30 and which are rotatable relative to the first pivot parts 10 on the outside of the first pivot parts. A bearing 50 (first bearing 51) is provided around the axle member 30 between the left and right first pivot parts 10. Furthermore, a string member 40 which is supported by the first bearing 51 and can be wound around the first bearing 51 is provided in the space formed between the first pivot parts 10.

[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 outboard of the main body 11 and has a smaller diameter than the main body 11. The main body 11 and the interlocking member 12 are formed as separate members as described below, 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 member having the greatest thickness. It has a circular recess 11c on the outer surface side in the axial direction. The recess 11c has an annular abutment 11d at the bottom thereof, which protrudes outward in the axial direction. In the present embodiment, the abutment 11d is described as being annular, but is not limited to such a shape. For example, a plurality of abutment 11d may be provided in a configuration in which they are spaced apart from each other by a predetermined distance.

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

[0031] The second rotating part 20 is disposed on the outer side of the interlocking member 12 in the axial direction, and has a substantially flat side surface 20a parallel to the rotating surface 12a. The outer peripheral end 20b of the side surface 20a extends inward in the axial direction, and the extended tip edge 20c faces the abutment part 11d. That is, the end surface side of the second rotating part 20 is appropriately curved so as to cover the side surface side and the end surface side of the interlocking member 12. Therefore, the second rotating part 20 forms a space SP between itself and the recessed part 11c of the first rotating part 10. It is desirable that the abutment part 11d and the tip edge 20c are spaced apart 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 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 described below. Here, since the pivoting surface 12a is disposed close to the second pivoting portion 20, the first marking i1 can be seen clearly. Furthermore, if the second pivoting portion 20 includes a lens-shaped portion, it is possible to change the size of the first marking i1 when it is viewed.

[0034] Additionally, a recess 21 is formed in the side surface 20a of the second pivoting part 20 at a position facing the shaft member 30. This recess 21 can be used to make it easier to hold the yo-yo 1. When the left and right side surfaces 20a of the second pivoting part 20 are gripped by pressing firmly, the abutment portion 11d can abut against the leading edge 20c of the second pivoting part 20. However, when the abutment portion 11d abuts against the leading edge 20c, the second pivoting part 20 and the pivoting surface 12a of the interlocking member 12 are configured to be separated from each other, thereby preventing the second pivoting part 20 and the pivoting surface 12a of the interlocking member 12 from coming into contact with each other, and preventing their movements from being hindered. It is desirable to adjust the protruding length of the abutment portion 11d so that when the yo-yo 1 is not being held, the distance between the rotation surface 12a of the interlocking member 12 and the second rotation portion 20 facing the rotation surface 12a is greater than the distance between the tip of the abutment portion 11d and the tip edge 20c. In this embodiment, the tip edge 20c is described as being configured to face the abutment portion 11d, but this is not limited to this. It is sufficient that a part of the second rotation portion 20 can abut the abutment portion 11d facing it, and when they abut, the second rotation portion 20 and the rotation surface 12a of the interlocking member 12 are configured to be separated. However, by adopting the configuration of this embodiment, it is desirable because it is not necessary to newly provide a protruding portion such as the abutment portion 11d on the second rotation portion 20.

[0035] An example of how to assemble yo-yo 1 will now be described 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 part 10 is assembled first, as shown in Figure 3. In this case, the nut 70 is placed in the central recess 11g of the main body 11. Meanwhile, the second bearing 52 is inserted from the inside into the inner recess 12e of the interlocking member 12, and a bearing holding member 71 that is fixed 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 11. This causes the second bearing 52 to be sandwiched and fixed between the main body 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] Here, the rotation surface 12a and the outer peripheral surface 12b of the interlocking member 12 have a first display area E1 in which a first sheet 81 and a third sheet 83 are provided, as shown in FIG. 5. In this first display area E1, the first information i1, which is a geometric pattern such as a polka dot pattern, is arranged. In addition, the second rotation part 20 has a second display area E2 in which a second sheet 82 is provided as described above. In this second sheet 82, the second information i2, such as a specific character, is displayed. In order to further improve the decorativeness of the first information i1 and the second information i2, it is preferable that the first information i1 is displayed entirely in the first display area E1, and the second information i2 is arranged in a part of the second display area E2. In addition, it is preferable that the second information i2 is not displayed in the center of the second display area E2 in order to improve the visibility of the first information i1. Moreover, it is more preferable that the second marking i2 is displayed near the outer periphery of the second display region 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 part 20, or may cover only a part of it. Here, the area of ​​the second display region E2 is configured to be larger than the area of ​​the first display region E1, and when it covers almost the entire outer surface, it is made of a light-transmitting material. This improves the visibility of the first display region E1.

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

[0040] The same assembly of the first rotating part 10 and the second rotating part 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 the shaft member 30 through which the first bearing 51 passes are screwed into the left and right nuts 70 to assemble. In this manner, the yo-yo 1 shown in Figure 1 is assembled.

[0041] Fig. 7 is a side view of yo-yo 1 shown in Fig. 1. Fig. 8 is a side view of main body 11 of yo-yo 1 shown in Fig. 1 in a rotating state. When the first rotating part 10 of the yo-yo 1 is not being rotated, the second information i2 (design of a character (a whale)) and the first information i1 (polka dots) are visible simultaneously, as shown in Figure 7. On the other hand, when the first rotating part 10 is rotating (when the yo-yo 1 is in use), the first information i1 is a concentric striped pattern rather than a polka dot pattern, as shown in Figure 8. In other words, the first information 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 rotating part 20 can be configured as shown in FIG. 9. The second rotating part 20 shown in FIG. 9 is different from the configuration shown in FIG. 2 in that the outer surface side is not a substantially flat side surface part 20a, but 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 rotating part 20 can function as a convex lens. This allows the first information i1 to appear enlarged, and the shape of the first information i1 to appear to change depending on the viewing direction. In this modified example, the second sheet 82 is configured to be provided only on a part of the outer side of the second rotating part 20.

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

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

[0045] Furthermore, in this embodiment of yo-yo 1, second rotating portion 20 is configured so that outer peripheral surface 12b of interlocking member 12 is visible, making it possible to create a visual effect not only on the side of yo-yo 1 but also on the end surface (thickness side of yo-yo 1). Furthermore, in this embodiment of yo-yo 1, interlocking member 12 has a different visual effect from main body portion 11, which increases the decorativeness. As a visual effect, for example, the color effect can be enhanced by changing the color, and the first marking i1 and second marking i2, which are provided adjacent to each other, can be decorated with 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 pictures on second pivoting part 20 and interlocking member 12. Furthermore, it is possible to present a visually different image when yo-yo 1 is stationary (when first pivoting part 10 is not rotating) and 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 to 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, making it possible to see an enlarged view of the first information i1 of the interlocking member 12.

[0048] In this embodiment of yo-yo 1, main body 11 and interlocking member 12 are configured to be connected by connecting member 60, so the combination of main body 11 and interlocking member 12 can be easily changed. Also, second bearing 52 is positioned so as to be sandwiched between main body 11 and interlocking member 12, so that second bearing 52 can be held and fixed when interlocking member 12 is assembled. This simplifies the structure of yo-yo 1 and makes assembly easier.

[0049] In the yo-yo 1 of this embodiment, a recess 21 is formed in side surface 20a of second pivoting part 20, making it easy to hold yo-yo 1. Furthermore, because tip edge 20c of second pivoting part 20 is located in a position opposite abutment portion 11d, for example, when gripping the left and right side surfaces 20a of second pivoting part 20 in a manner that presses them, even if the second pivoting part 20 is pressed with a large force, abutment portion 11d and tip edge 20c will abut, while second pivoting part 20 and pivot surface 12a of interlocking member 12 will be separated and a gap will be maintained, 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 both the rotation surface 12a of the interlocking member 12 and the outer circumferential surface 12b of the interlocking member 12, but the present invention is not limited to this and may be either one of them.
