[0005] Patent Document 1: Japanese Utility Model Registration No. 3075714 Summary of the Invention

[0006] The problem the invention aims to solve

[0007] In toys with a launching tower, even if the guide rail is extended, the balls can roll from the ball receiving part to the launching part, but the toy's structure becomes larger. Moreover, this tower toy cannot be combined with other block toys and is intended for use alone.

[0008] In order for a rolling object to roll on a track component that has both inclined and horizontal sections, the height of the feed section needs to be set relatively high, or the length of the horizontal section needs to be set relatively short. If the rotating object can roll to the downstream end of the horizontal section without making the feed section too high, the user's enjoyment of the rolling object's movement can be increased.

[0009] The purpose of this invention is to enhance the fun of rolling toys with track components and rolling elements.

[0010] Solution for solving the problem

[0011] One technical solution of the present invention is a rolling toy, which includes a rolling body and a track component forming a track for the rolling body to roll, wherein the rolling body has a first rolling part that engages with the track component in a first range of the track component and separates from the track component in a second range of the track component that is different from the first range, and the track component restricts the movement of the rolling body to rotational movement in the first range.

[0012] The effects of the invention

[0013] For rolling toys, the rolling element has both a rolling motion that engages with the track component and a rolling motion that separates from the track component, which can enhance the fun of the rolling toy. Attached Figure Description

[0028] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Figure 1 This indicates the state in which the rolling toy 10 is assembled on the base plate 11. The base plate 11 is quadrilateral, and multiple fitting parts 12 are arranged in a checkerboard pattern on its surface. The intervals of the fitting parts 12 along the direction of the edge of the base plate 11 are all the same, and the protrusion heights from the surface are also all the same.

[0029] Multiple blocks can be installed in a removable manner on the base plate 11. Figure 1 In this configuration, a ramp block 13 and a straight guide rail block 14 are assembled on the base plate 11, with the guide rail block 14 connected to the ramp block 13. A curved guide rail block 15 is also assembled on the base plate 11, connected to the ramp block 13 via the guide rail block 14. Two straight guide rail blocks 16 are interconnected and assembled on the base plate 11, connected to the ramp block 13 via the guide rail blocks 15, etc. The guide rail block 16 is longer than the guide rail block 14; a shorter guide rail block 14 and a longer guide rail block 16 are assembled on the base plate 11.

[0030] Each block 13 to 16 has a mating part on its bottom surface for mating part 12 to fit into. By mating the mating part with the mating part 12, each block is assembled onto the base plate 11 in a detachable manner. Regarding each block 13 to 16, the following description will be based on the state of assembly onto the horizontally supported base plate 11, indicating their vertical and horizontal positional relationships.

[0031] like Figure 1 As shown, the ramp block 13 is positioned on the inner side of the base plate 11, and the guide rail blocks 14-16 are arranged in an L-shape and connected to the ramp block 13. The recovery tray block 17 is assembled on the right side of the base plate 11. The rolling element 20, fed into the feed section of the ramp block 13, then rolls or rotates along the ramp block 13 and the guide rail blocks 14-16, and is recovered to the recovery tray block 17. The recovery tray block 17 has an assembly section 17a assembled to the base plate 11 and a recovery section 17b connected to the assembly section 17a.

[0032] The arrangement of the ramp block 13 and the various guide rail blocks 14-16 can be freely set by the player. Furthermore, in addition to the aforementioned blocks, various other blocks such as table blocks, figure blocks, house blocks, and door blocks can be assembled onto the base plate 11. This allows players to enjoy many assembly modes, enhancing the fun of the rolling toy.

[0033] like Figure 2 and Figure 3 As shown, the rolling element 20 has a rotating shaft portion 21 as a first rolling part and two disk portions 22 as second rolling parts. The two disk portions 22 are located at both ends of the rotating shaft portion 21. In this embodiment, the radius R1 of the disk portions 22 is greater than the radius R2 of the rotating shaft portion 21. The radius difference (R1-R2) between the radius R1 of the disk portions 22 and the radius R2 of the rotating shaft portion 21 is set as ΔR. The rolling element 20 is capable of rotating about the rotation center axis O. Gear-shaped protrusions and recesses 23 with multiple protrusions extending axially are provided on the outer periphery of the rotating shaft portion 21. Thus, the rolling element 20 has a rotating shaft portion 21 with gear-shaped protrusions and recesses 23 on its outer periphery and disk portions 22 located at both ends of the rotating shaft portion 21 in a manner that clamps the rotating shaft portion 21. The inner surface 24 of the disk portion 22 is a generally conical surface that is inclined axially outward from the rotating shaft portion 21 toward the outer periphery of the disk portion 22. Figure 3 As shown in (A), it is slightly curved into a convex shape.

[0034] like Figure 2 As shown, four fitting portions 25 protrude axially from the outer surface of the disc portion 22 forming the outer surface of the rolling element 20. If the cover member 26, as an accessory component, is fitted into each fitting portion 25, then... Figure 1 As shown, the cover member 26 is mounted on the outer side of the disc portion 22. The cover member 26 has a fitting portion (not shown) that can be detachably fitted with the fitting portion 25. Since the cover member 26 is detachable, if multiple cover members 26 with different patterns or colors are prepared in advance, the player can enjoy the combination of the rolling body 20 and the cover member 26. Figure 2 and Figure 3 In the middle, the cover component 26 is shown by a double-dotted line.

[0035] like Figure 4 and Figure 5As shown, the ramp block 13 has a first track portion 31 at its center in the width direction and second track portions 32 extending along the first track portion 31 on both sides in the width direction, thus constituting a track member 30. The surface positions of the surface 33 of the first track portion 31 and the surface 34 of the second track portion 32 are different from each other, with the surface position of the surface 33 of the first track portion 31 being higher than the surface position of the surface 34 of the second track portion 32. Thus, in this embodiment, the ramp block 13 has a convex shape having a first track portion 31 as the higher track portion and a second track portion 32 as the lower track portion.

[0036] The ramp block 13 has a fitting portion 18 with an opening on its bottom surface 35. When the fitting portion 12 of the base plate 11 is fitted with the fitting portion 18, the ramp block 13 is assembled onto the base plate 11 and held in that position. The other guide rail blocks 14-16 and the recovery tray block 17 also have similar fitting portions. Figure 1 All the blocks shown are mounted on the base plate 11 to form the track component 30. The rolling toy is a toy that includes the rolling body 20 and the track component 30.

[0037] like Figure 5 As shown, the height dimension H1 from the bottom surface 35 to the surface 33 at one end of the ramp block 13, which is the track component 30, is greater than the height dimension H2 from the bottom surface 35 to the surface 33 at the other end. Similarly, the height dimension J1 from the bottom surface 35 to the surface 34 at one end of the ramp block 13 is greater than the height dimension J2 from the bottom surface 35 to the surface 34 at the other end.

[0038] One end of the track component 30 forms an infeed portion 41 for feeding the rolling element 20, and the other end forms an outfeed portion 42 for discharging the rolling element 20. An inclined portion 43 and a bridging portion 44 are provided in the region between the infeed portion 41 and the outfeed portion 42. The inclined portion 43 is connected to the infeed portion 41, and the bridging portion 44 is connected to the inclined portion 43. Both the inclined portion 43 and the bridging portion 44 are inclined downwards in a direction where their height decreases towards the outfeed portion 42. The bridging portion 44 is connected to a horizontal portion 45. The inclination angle of the bridging portion 44 is smaller than the inclination angle of the inclined portion 43.

[0039] The side 36 of the first track section 31 is inclined in the direction in which the width of the ramp block 13 widens toward the second track section 32.

[0040] The feed section 41 and the inclined section 43 have fixed-side protrusions 46 on their surfaces 33. The protrusions 46 are formed by providing protrusions that extend in a stripe-like pattern along the width direction of the ramp block 13 at predetermined intervals on the surfaces 33. The protrusions 46 are rack teeth that mesh with gear-shaped protrusions 23, constituting engagement parts of the track component that engage with the rotating shaft 21, which is the first rolling part. Therefore, when the rolling element 20 moves in the feed section 41 and the inclined section 43, the protrusions 23 engage with the protrusions 46, so the rolling element 20 will not slide on the inclined section 43, and the movement of the rolling element 20 is restricted to rotational movement.

[0041] like Figure 5 As shown, in the ramp block 13, the area with the protrusions 46 is designated as the first range L1, and the area of ​​the delivery portion 42 without the protrusions 46 is designated as the second range L2. The first range L1 has a delivery portion 41 and an inclined portion 43, and the delivery portion 42 of the second range L2 has a bridging portion 44 and a horizontal portion 45.

[0042] The distance between the surface 33 of the first track portion 31 and the surface 34 of the second track portion 32 within the first range L1, i.e., the protrusion length D1 of the first track portion 31 relative to the second track portion 32 within the first range L1, is set to be longer than the protrusion length D2 of the first track portion 31 relative to the second track portion 32 within the second range L2 (D1 > D2). Moreover, the protrusion length D1 is longer than the radius difference ΔR of the rolling element 20, and the protrusion length D2 is shorter than the radius difference ΔR (D1 > ΔR, D2 < ΔR).

[0043] When the rolling element 20 is fed into the feeding portion 41 of the ramp block 13, within the first range L1, the rotating side of the rotating shaft portion 21 engages with the fixed side of the rotating side of the rotating shaft portion 21, and within the second range L2, the rotating shaft portion 21 separates from the track member 30. That is, in the rolling element 20, the rotating shaft portion 21 constitutes a first rolling portion opposite to the first track portion 31. In contrast, the disc portion 22 of the rolling element 20 separates from the second track portion 32 of the track member 30 within the first range L1, and contacts the second track portion 32 within the second range L2. That is, in the rolling element 20, the disc portion 22 constitutes a second rolling portion opposite to the second track portion 32.

[0044] Therefore, for the rolling body 20 supplied to the feed portion 41 of the ramp block 13, which serves as the track component 30, the concave-convex portion 23 of the rotating shaft portion 21 engages with the concave-convex portion 46 of the track component 30 in the feed portion 41 and the inclined portion 43, and rolls in the inclined portion 43 in an engaged state. Thus, the rolling body 20 does not slide and is reliably restricted to movement in a rotating state, thereby increasing the rolling speed. The rolling body 20 rotates to the second range L2 of the ramp block 13 in a state where the rolling speed is increased. Within the second range L2, the engagement between the rotating shaft portion 21 and the track component 30 is released, and the disc portion 22 rolls on the surface 34 of the second track portion 32. In this way, the rolling body 20 switches from a state where the rotating shaft portion 21 is engaged with the track component 30 to a state where the disc portion 22 is in contact with the track component 30, thus increasing the fun of the rolling toy.

[0045] Each guide block 14-16 and the recovery tray block 17 has a surface at the same height as the surface 33 of the first track portion 31 and the surface 34 of the second track portion 32 at the horizontal portion 45 of the ramp block 13. Therefore, the rolling element 20 can pass through the second range L2 at a rolling speed increased during its movement to the horizontal portion 45, and then travel by inertia through the guide blocks 14-16 to the recovery tray block 17. All the guide blocks and the recovery tray block constitute the second range of the track component 30, which is connected to the second range L2 of the ramp block 13. Thus, the track component 30 can be formed solely of the ramp block 13 as a single block, or it can be formed from multiple blocks including the guide blocks 14-16.

[0046] The rolling element 20 supplied to the ramp block 13 has its rolling speed reliably increased in the inclined section 43. Within the second range L2, the disc portion 22, whose diameter is larger than that of the rotating shaft portion 21, acts as a rolling wheel and rolls, thus enabling it to travel a relatively long distance from the recovery tray block 17 in an inertial travel section. Furthermore, for the rolling element 20, within the first range L1, the groove 23 of the rotating shaft portion 21, which acts as a gear, engages with the groove 46 of the inclined section 43, which acts as a rack tooth, thus producing a clicking or meshing sound. In contrast, within the second range L2, the larger diameter disc portion 22 acts as a rolling wheel, producing a rolling sound different from this clicking or meshing sound. In this way, the rolling element 20 can possess multiple rolling sound patterns, enhancing the player's enjoyment through the generated sounds.

[0047] Figure 6 (A) is a front view of the ramp block 13 with the rolling element 20 disposed in the feed section 41 of the ramp block 13. Figure 6 (B) is a front view of the ramp block 13 in the state where the rolling element 20 has moved to the delivery part 42.

[0048] like Figure 6As shown in (A), for the rolling element 20 within the first range L1, the rotating shaft portion 21 engages with the protrusion 46, which serves as the track component 30, and the disc portion 22 separates from the track component 30. Therefore, when the rolling element 20 rolls within the first range L1, the rolling resistance exerted by the disc portion 22 on the rolling element 20 due to contact with the track component 30 can be suppressed.

[0049] On the other hand, such as Figure 6 As shown in (B), within the second range L2, for the rolling element 20, the rotating shaft portion 21 separates from the surface 33 of the first track portion 31, and the disk portion 22 contacts the surface 34 of the second track portion 32. At this time, the side surface 36 of the first track portion 31 is inclined, and the inner side surface 24 of the disk portion 22 is approximately conical in shape and slightly convexly curved, so the inner side surface 24 of the rolling element 20 makes point contact with the side surface 36 of the first track portion 31. In this way, the inner side surface 24 makes point contact with the track member 30, so when the disk portion 22 is rolled as a rolling wheel, the rolling resistance applied to the rolling element 20 by the track member 30 can be suppressed.

[0050] Figure 7 The guide block 14 is shown in magnified form as a short-length straight line. Figure 8 Enlarged view of the curved guide block 15. Figure 9 Guide block 16, enlarged representation of a long straight line.

[0051] like Figure 7 As shown, the short, straight guide block 14 has a higher first track portion 51 in the central part of the width direction and lower second track portions 52 on both sides in the width direction, thus forming a straight track component. The surface 53 of the first track portion 51 protrudes relative to the surface 54 of the second track portion 52, and the two surfaces 53 and 54 are parallel. The height dimension of the surface 53 of the first track portion 51 from the bottom surface 55 is approximately the same as the height dimension H2 of the surface 33 of the first track portion 31 at the end face of the delivery side of the ramp block 13. In addition, the height dimension of the surface 54 of the second track portion 52 from the bottom surface 55 is approximately the same as the height dimension J2 of the surface 34 at the end face of the delivery side of the second track portion 32. The side surface 56 of the first track portion 51, like the side surface 36 of the ramp block 13, is inclined in the direction in which the width of the guide block 14 widens towards the second track portion 52.

[0052] like Figure 8As shown, the curved guide block 15 has a higher first track portion 61 at the center in the width direction and lower second track portions 62 on both sides in the width direction, thus forming a track component that is generally curved at 90 degrees when viewed from above. The surface 63 of the first track portion 61 protrudes relative to the surface 64 of the second track portion 62, and the two surfaces 63 and 64 are parallel. The height dimension of the surface 63 of the first track portion 61 from the bottom surface 65 is approximately the same as the height dimension H2 of the surface 33 of the first track portion 31 at the end face of the ramp block 13. In addition, the height dimension of the surface 64 of the second track portion 62 from the bottom surface 65 is approximately the same as the height dimension J2 of the surface 34 at the end face of the second track portion 32. The side surface 66 of the first track portion 61, like the side surface 36 of the ramp block 13, is inclined in the direction that the width increases towards the second track portion 62.

[0053] like Figure 9 As shown, the long linear guide block 16 is the same as the one with the same length except for the length. Figure 7 The short-sized guide block 14 shown has a roughly the same construction. Figure 9 In the middle, to and Figure 7 Parts that share common features are labeled with the same reference numerals, and repeated descriptions are omitted.

[0054] like Figure 1 As shown, when the guide rail blocks 14-16 and the recovery tray block 17 are connected to the ramp block 13 and arranged on the base plate 11, the surfaces 53 and 63 of the first track portions 51 and 61 of each guide rail block 14-16 have the same height dimension H2 as the end face of the first track portion 31 of the ramp block 13, and the surfaces 54 and 64 of the second track portions 52 and 62 have the same height dimension J2 as the end face of the second track portion 32 of the ramp block 13. Furthermore, the end face of the assembly portion 17a of the recovery tray block 17 has the same shape as the end face of each guide rail block.

[0055] like Figure 1 As shown, with each guide block assembled on the base plate 11, a second range L2 is formed from the guide block 14 to the assembly portion 17a, which serves as the assembled track component 30. Therefore, when the rolling element 20 rolls from the ramp block 13 to the recovery portion 17b of the recovery tray block 17 via the guide blocks 14-16, similarly to when the rolling element 20 rolls within the second range L2 of the ramp block 13, the rotation axis portion 21 of the rolling element 20 separates from the surface of the first track portion, and the disc portion 22 contacts the surface of the second track portion. At this time, the inner surface 24 of the rolling element 20 makes point contact with the side surface of the first track portion, thus suppressing the rolling resistance applied to the rolling element 20 from the guide blocks, which are track components, when the disc portion 22 is rolled as a rolling wheel.

[0056] Figure 10 and Figure 11 These are side views of modified examples 1 and 2 of the ramp block, respectively. Figure 10 The ramp block shown is formed by assembling a first ramp block 13a and a second ramp block 13b. The first ramp block 13a has the same characteristics as... Figure 5 The second ramp block 13b has the same length as the first range L1 of the ramp block 13, and has a second range L2 feed-out section 42 that is longer than the second range L2 of the ramp block 13. Thus, in Figure 10 The image shows a ramp block assembled from two blocks: a first ramp block 13a having an infeed section 41 and an inclined section 43, and a second ramp block 13b having an outfeed section 42.

[0057] Figure 11 The ramp block shown is formed by assembling a first ramp block 13c and a second ramp block 13d. The first ramp block 13c has a feeding portion 41 and an inclined portion 43a, and its length is L3. The second ramp block 13d has an inclined portion 43b and a feeding portion 42, and its length is L4. The combined length of the inclined portions 43a and 43b of the first ramp block 13c and the second ramp block 13d is L4. Figure 5 The inclined portion 43 of the ramp block 13 shown is the same. Figure 11 The ranges L1 and L2 in the text correspond to Figure 10 The first range L1 and the second range L2 are in the middle. In this way, the inclined part 43 can also be assembled by multiple ramp blocks.

[0058] Alternatively, in each ramp block, the feeding part 41 may be omitted, and instead an inclined part 43 may be provided from one end face.

[0059] Figure 12 This is a side view showing a variation of a rolling toy. Figure 12 The diagram shows a ramp block 13e and a rolling element 20a, indicated by an imaginary line. The rolling element 20a is shown in its state as disposed in the feed section 41 of the ramp block 13e and in its state as it rolls to the feed section 42.

[0060] Rolling element 20a, like rolling element 20, has a rotating shaft portion 21 and disk portions 22 located at both ends of the rotating shaft portion 21. However, the disk portions 22 have a rotating-side protrusion / recess 23 on their outer peripheral surface, while the rotating shaft portion 21 does not have a protrusion / recess 23. On the other hand, the ramp block 13e and... Figure 5The ramp block shown also has a first track portion 31 and a second track portion 32. However, the surface 34 of the second track portion 32 has a fixed-side protrusion 46, while the first track portion 31 does not have a protrusion. Thus, in the rolling element 20a, the disk portion 22 constitutes the first rolling element, and the rotating shaft portion 21 constitutes the second rolling element. In the rolling element 20a, the rotating shaft portion 21 separates from the first track portion 31 of the ramp block within a first range L1 and contacts the first track portion 31 within a second range L2. That is, in the rolling element 20a, the rotating shaft portion 21 constitutes the second rolling element.

[0061] In ramp block 13e, the protruding length D1 of the first track portion 31 within the first range L1 is shorter than the protruding length D2 within the second range L2 relative to the second track portion 32. Furthermore, the first range L1 and the second range L2 of ramp block 13e are... Figure 5 The first and second ranges shown have the same length.

[0062] As another variation of the rolling toy (not shown), the ramp block 13 can also be constructed from a concave shape formed by a first track portion 31 (as a higher track portion) sandwiching a second track portion 32 (as a lower track portion). In this other variation, the rolling element 20 is composed of a disc portion 22 and two rotating shaft portions 21 sandwiching the disc portion 22. Furthermore, a concave-convex portion 46 that restricts the movement of the rolling element 20 to rotational movement can be provided on the first track portion 31 of the ramp block 13; in this case, a concave-convex portion 23 is provided on the rotating shaft portion 21 of the rolling element 20. On the other hand, a concave-convex portion 46 that restricts the movement of the rolling element 20 to rotational movement can also be provided on the second track portion 32 of the ramp block 13; in this case, a concave-convex portion 23 is provided on the disc portion 22 of the rolling element 20.

[0063] This invention is not limited to the described embodiments and variations, and various modifications can be made without departing from its spirit. For example, the ramp block and guide rail block described above may not be mounted on the base plate, but may be arranged on the worktable or the like in a connected state as a form that can be directly connected.
