[0089] Hereinafter, a yo-yo as one embodiment of the present invention will be described with reference to the drawings.

[0090] Figure 1 is a front view of the yo-yo 1, Figure 2 It is a cross-sectional view showing the inside of the yo-yo 1.

[0091] Figure 1 and Figure 2 The yo-yo 1 shown in the figure includes a shaft member 30, a pair of left and right first rotating parts 10 that can rotate around the shaft member 30, and a pair of left and right second rotating parts 20 that can rotate around the shaft member 30 and can rotate relatively with respect to the first rotating parts 10 outside the first rotating parts. In addition, between the left and right first rotating parts 10, a bearing 50 (first bearing 51) is provided around the shaft member 30. In addition, in the space formed between the first rotating parts 10, a rope member 40 that is supported by the first bearing 51 and can be wound around the first bearing 51 is provided.

[0092] The first rotating part 10 is a structure in which a disk-shaped main body part 11 rotatably supported by a shaft member 30 is integrally connected with a linkage member 12 having a smaller diameter than the main body part 11 on the axially outer side of the main body part 11. The main body part 11 and the linkage member 12 are formed as separate parts as described later, and the left and right parts are connected via the shaft member 30 to form an integral whole.

[0093] The main body 11 is configured as a component with the largest thickness. In addition, a circular recessed portion 11c is provided on the outer surface side in the axial direction. In the recessed portion 11c, an annular contact portion 11d protruding toward the axial outer side is provided at the bottom of the recessed portion 11c. In addition, although it is described in this embodiment that the contact portion 11d is annular, it is not limited to this shape, and for example, a plurality of contact portions 11d may be provided in a configuration separated from each other by a specified distance.

[0094] The linkage member 12 has a thin plate-shaped rotating surface 12a on the outer side surface in the axial direction, and the rotating surface 12a can rotate in conjunction with the main body 11 when it is installed on the main body 11. In other words, the rotating surface 12a is directed to the side of the yo-yo 1. The first sheet 81 is attached to the rotating surface 12a. In addition, the linkage member 12 has an outer peripheral surface 12b in a direction intersecting the rotating surface 12a, and the third sheet 83 is attached to the outer peripheral surface 12b.

[0095] The second rotating part 20 is arranged axially outward from the linkage member 12, and has a substantially flat side surface portion 20a parallel to the rotating surface 12a. The outer peripheral end 20b of the outer peripheral side of the side surface portion 20a is configured to extend toward the axial inner side, and the extended front end edge 20c is opposite to the abutment portion 11d. In other words, the second rotating part 20 is formed in a shape in which the end surface side is appropriately curved in a manner to cover the side surface and the end surface side of the linkage member 12. Therefore, the second rotating part 20 forms a space SP between the second rotating part 20 and the recessed portion 11c of the first rotating part 10. In addition, even when the yo-yo 1 is in use, it is preferable that the abutment portion 11d and the front end edge 20c are separated.

[0096] The second rotating part 20 is mounted on the first rotating part 10 via bearings 50 (second bearings 52) disposed on both ends of the shaft member 30, and is configured to be able to rotate 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 the second rotating part 20 can be observed through the second rotating part 20. Thus, although the interlocking member 12 is configured to have a different visual effect from the main body 11, the difference in visual effect between the main body 11 and the interlocking member 12 can be observed. For example, the visual effect can be a change in color or a change in glossiness.

[0097] In addition, when the yo-yo 1 is viewed from the side (refer to Figure 7 ), the rotating surface 12a of the linkage member 12 can be observed. Since the first sheet 81 is provided on the rotating surface 12a as described above, a pattern such as a water drop pattern as the first information i1 described later can be observed from the outside. Here, since the rotating surface 12a is arranged close to the second rotating part 20, the first information i1 can be clearly observed. In addition, in the case where the second rotating part 20 includes a lens-shaped portion, the size of the first information i1 can be changed to observe.

[0098] In addition, a recess 21 is formed in the side surface 20a of the second rotating part 20 at a position opposite to the shaft member 30. The recess 21 can be used as a structure for easy gripping when the yo-yo 1 is gripped. In addition, when the left and right side surface 20a of the second rotating part 20 are held by strongly pressing, the contact portion 11d is configured to contact with the front end edge 20c of the second rotating part 20. On the other hand, when the contact portion 11d contacts the front end edge 20c, the second rotating part 20 is separated from the rotating surface 12a of the linkage member 12, thereby preventing the second rotating part 20 from contacting the rotating surface 12a of the linkage member 12 and preventing their movements from being hindered. As a structure in which the second rotating part 20 is separated from the rotating surface 12a of the linkage member 12 when the front end edge 20c abuts against the second rotating part 20, when the yo-yo 1 is not held, it is preferable to adjust the protruding length of the abutting part 11d in advance so that the distance between the rotating surface 12a of the linkage member 12 and the second rotating part 20 opposite to the rotating surface 12a is greater than the distance between the front end of the abutting part 11d and the front end edge 20c. In addition, in the present embodiment, although it is described that the front end edge 20c is configured to face the abutting part 11d, it is not limited to this, as long as a part of the second rotating part 20 can abut against the abutting part 11d facing thereto, and when they abut, the second rotating part 20 is separated from the rotating surface 12a of the linkage member 12. However, by setting the structure in advance as in the present embodiment, it is not necessary to newly provide a protruding part such as the abutting part 11d on the second rotating part 20, so it is preferable.

[0099] Below, reference Figures 3 to 6 , an example of a method for assembling the yo-yo 1 is described.

[0100] Figure 3 yes Figure 1 A cross-sectional view of the yo-yo is shown in an early stage of assembly. Figure 4 yes Figure 1 A cross-sectional view of the assembled mid-section of the yo-yo is shown. Figure 5 yes Figure 4 A perspective view of the state shown. Figure 6 yes Figure 1 A cross-sectional view of the final assembly section of the yo-yo is shown.

[0101] When assembling the yo-yo 1, first Figure 3As shown, for example, the first rotating part 10 is assembled. In this case, on the main body 11 side, the nut 70 is embedded in the central recess 11g thereof. On the other hand, on the linkage member 12 side, the second bearing 52 is inserted from the inside into the recess 12e on the inside thereof, and the bearing holding member 71 fixed from the outside thereof is embedded in the second bearing 52. Then, a connecting member 60 such as a screw is screwed into the screw receiving portion 12d of the linkage member 12 from the main body 11 side. Thus, the second bearing 52 is sandwiched and fixed between the main body 11 and the linkage member 12.

[0102] Then, if Figure 4 As shown, the center boss portion 20f of the second rotating part 20 is embedded into the inner side of the second bearing 52 from the outer side of the linkage member 12. In addition, a rivet 61 is driven from the body portion 11 side to the center boss portion 20f, for example, from the outer side of the bearing holding member 71, to connect the first rotating part 10 and the second rotating part 20. Thus, the second rotating part 20 is rotatably connected to the first rotating part 10 via the second bearing 52.

[0103] Here, if Figure 5 As shown, the first display area E1 in which the first sheet 81 and the third sheet 83 are provided is provided on the rotating surface 12a and the outer peripheral surface 12b of the linkage part 12. The first information i1 of a geometric figure such as a water drop pattern is arranged in the first display area E1. In addition, the second rotating part 20 has a second display area E2 in which the second sheet 82 is arranged as described above. The second information i2 such as a specific character is displayed on the second sheet 82. In order to further improve the decorativeness of the first information i1 and the second information i2, it is preferred that the first information i1 is displayed as a whole 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 preferred that in order to improve the visibility of the first information i1, the second information i2 is not displayed in the central part of the second display area E2. In addition, it is further preferred that in order to improve the visibility of the relative movement with the first information i1, the second information i2 is displayed near the periphery of the second display area E2. In addition, the second sheet 82 may be circular and cover the entire outer surface of the second rotating portion 20, or may cover a portion of the outer surface. Here, the second display area E2 is configured to have an area larger than the first display area E1, and in the case of covering the entire outer surface, the second sheet 82 is made of a light-transmitting material. Thus, the visibility of the first display area E1 is improved.

[0104] By configuring the second rotating part 20 in this way, when the yo-yo 1 is viewed from the front, Figure 1 As shown, the outer peripheral surface 12b of the linkage member 12 can be observed, and when viewed from the side, the rotation surface 12a can be observed.

[0105] The first rotating part 10 and the second rotating part 20 are also assembled on the other side to form a pair of left and right parts. Figure 6 As shown, the two ends of the shaft member 30 that passes through the first bearing 51 are screwed into the left and right nuts 70 for assembly. Figure 1 The yo-yo 1 is shown.

[0106] Figure 7 yes Figure 1 A side view of a yo-yo 1 is shown. Figure 8 yes Figure 1 The yo-yo 1 is shown in a side view in which the main body 11 is rotated.

[0107] When the yo-yo 1 does not rotate the first rotating part 10, Figure 7 As shown in FIG. 1 , the second information i2 (character (whale) pattern) and the first information i1 (water drop pattern) can be observed simultaneously. On the other hand, when the first rotating part 10 is rotating (the yo-yo 1 is in use), as shown in FIG. Figure 8 As shown, the first information i1 is not a water drop pattern but a concentric stripe pattern. That is, the first information i1 of the first display area E1 is visually different when the interlocking member 12 is rotating and when it is stationary.

[0108] Fig. 9 It is a cross-sectional view showing a modified example of the present invention.

[0109] In the present invention, the second rotating part 20 can be Fig. 9 As shown. Fig. 9 The second rotating part 20 shown in FIG. Figure 2 The configuration shown is different, and the side surface portion 20a is not substantially flat on the outer surface side, but is configured as a curved surface that expands in the extension direction (left-right direction) of the shaft member 30. In this case, the second rotating portion 20 can make its side surface as a whole function as a convex lens. Thus, the first information i1 can be observed after being magnified, and the shape of the first information i1 is observed according to the change in the observation direction. In addition, in this variation, the second sheet 82 is configured as a portion that is only provided on the outer side of the second rotating portion 20.

[0110] As described above, in the yo-yo 1 of this embodiment, the second rotating part 20 covering the main body 11 of the yo-yo 1 from the outside is configured so that the inside can be observed, and in addition to the information such as the pattern set on the second rotating part 20 constituting the outermost surface, the internal information can also be seen.

[0111] Furthermore, in the yo-yo 1 of this embodiment, by providing the interlocking member 12 between the main body 11 and the second rotating portion 20 , the interlocking member 12 can be used as an image display portion that can be viewed through the second rotating portion 20 .

[0112] In the yo-yo 1 of this embodiment, the outer peripheral surface 12b of the interlocking member 12 is also visible from the second rotating part 20, so that not only the side surface of the yo-yo 1 but also the end surface (the thickness side of the yo-yo 1) can be viewed. In the yo-yo 1 of this embodiment, the interlocking member 12 has a different visual effect from the main body 11, so that the decorative effect is improved. As a visual effect, for example, the color effect can be improved by changing the color, and the first information i1 and the second information i2 arranged adjacent to each other can be decorated with different colors.

[0113] In the yo-yo 1 of this embodiment, since the interlocking member 12 can be observed through the second rotating portion 20, it is possible to overlap information such as patterns provided on the second rotating portion 20 and the interlocking member 12. In addition, it is possible to produce visually different images when the yo-yo 1 is in a stationary state (a state where the first rotating portion 10 is not rotating) and when it is rotating.

[0114] In the yo-yo 1 of this embodiment, the second rotating part 20 is configured in a dome shape that expands toward the opposite side of the first rotating part 10, so that the yo-yo 1 can be easily gripped. In addition, when the second rotating part 20 is configured of a transparent member, it can be configured as a convex lens, and the first information i1 of the interlocking member 12 can be magnified and observed.

[0115] In the yo-yo 1 of this embodiment, since the main body 11 and the interlocking member 12 are connected by the connecting member 60, the combination of the main body 11 and the interlocking member 12 can be easily changed. In addition, the second bearing 52 is arranged so as to be sandwiched between the main body 11 and the interlocking member 12, and the second bearing 52 can be held and fixed when the interlocking member 12 is assembled. Thus, the structure of the yo-yo 1 can be simplified, and assembly can be facilitated.

[0116] In the yo-yo 1 of this embodiment, the recessed portion 21 is formed in the side surface portion 20a of the second rotating portion 20, so that the yo-yo 1 is easy to hold when being held. In addition, since the front edge 20c of the second rotating portion 20 is provided at a position opposite to the contact portion 11d, for example, when the second rotating portion 20 is held by pressing the left and right side surface portions 20a of the second rotating portion 20, the contact portion 11d contacts the front edge 20c even when the pressing is performed with a large force, and since the second rotating portion 20 and the rotating surface 12a of the interlocking member 12 are separated and a gap is maintained, it is possible to prevent the movement of the second rotating portion 20 from being hindered.

[0117] Although one embodiment of the present invention has been described above, the present invention can be appropriately modified within the scope of its technical concept. For example, in the embodiment described above, although the first display area E1 is set to both the rotation surface 12a of the linkage component 12 and the outer peripheral surface 12b of the linkage component 12, the present invention is not limited thereto and can be either one.
