DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, a toy top set and a toy top according to an embodiment of the present invention will be described with reference to the drawings.

[0016] (First embodiment) FIG. 1 is a perspective view of a toy spinning top set 100. FIG. This toy top set 100 includes toy tops 10 and a stadium 50A for battling the toy tops 10.

[0017] (Toy top 10) 2 is a front view of the toy top 10. The toy top 10 is generally made of plastic. The toy top 10 comprises a body 11 and a shaft 12A. The body 11 is a composite part. The body 11 has an uneven surface formed around the entire periphery. The shape of the uneven surface affects the offensive and defensive capabilities of the toy top during battle.

[0018] An attachment part 13 is provided at the lower end of the body part 11. The shaft part 12A is detachably attached to the attachment part 13. 3 is a front view of the shaft portion 12A. The shaft portion 12A is provided with a rotary shaft 14. The lower end of the rotary shaft 14 forms a ground contact portion 14a. Engagement recesses 15 are formed at predetermined intervals around the entire circumferential area of ​​the rotating shaft 14 on the outer periphery of the vertically middle portion of the rotating shaft 14. Meanwhile, as shown in FIG. 4 , a hole 16 for fitting the rotating shaft 14 is formed in the mounting portion 13. Resilient claws 17 that engage with the engagement recesses 15 are provided within the hole 16. Two resilient claws 17 are provided on either side of the central axis of the hole 16. The shank 12A is attached to the mounting portion 13 by engaging the resilient claws 17 with the engagement recesses 15. When the shank 12A is attached to the mounting portion 13, the upper end of a rise portion 19 (described below) abuts against the lower end of the mounting portion 13. This abutment stably holds the shank 12A on the trunk 11. The shank 12A rotates integrally with the trunk 11. The shank 12A can be removed from the trunk 11 by manually pulling it downward relative to the trunk 11.

[0019] A gear 18A is provided directly above the ground contact portion 14a of the rotating shaft 14. The center line of the rotating shaft 14 and the center line of the gear 18A are aligned. The gear 18A is a tapered gear whose diameter increases as it goes downward.

[0020] Furthermore, a flange-like projection 19 is provided on the rotary shaft 14 directly above the gear 18A and below the engagement recess 15. The lower surface of the projection 19 forms an axisymmetric sliding surface 19a whose lower end is the same shape as the circumscribing circle of the upper end of the gear 18A and whose diameter increases as it goes upward in the axial direction.

[0021] (Stadium 50A) The stadium 50A shown in FIG. 1 is constructed of transparent polyvinyl chloride. Stadium 50A constitutes the field where the top battles are held, and comprises a base plate 51 and a cover body 52 mounted on top plate 51 and having a circular opening 52a in the ceiling. A bowl-shaped recess 53 is formed in the center of the floor of the field. A cant (slope) is formed around recess 53, along which toy tops 10 can run. A step 54 is formed on the outside of this cant. Step 54 serves as the boundary between the lower and upper levels of the field.

[0022] The upper part of the step part 54 is made up of an acceleration rail 55. The acceleration rail is made up of a rack 56A that can mesh (engage) with the gear 18A. The rack 56A constitutes part of the step part 54 and also constitutes part of the upper floor.

[0023] (Relationship between shaft 12A and rack 56A) When rack 56A and gear 18A mesh, ground contact portion 14a of rotating shaft 14 is configured to move away from the floor below. That is, in this toy top set 100, when toy top 10 running around on the lower floor comes into contact with step portion 54, sliding surface 19a of climbing portion 19 first comes into contact with the upper corner of step portion 54. Then, due to the sliding contact between sliding surface 19a and step portion 54, when climbing portion 19 rides up onto step portion 54, ground contact portion 14a of rotating shaft 14 moves away from the floor below, and gear 18A meshes with rack 56A. In other words, when the ground contact portion 14a of the rotary shaft 14 does not separate from the floor of the lower floor, the gear 18A does not mesh with the rack 56A.

[0024] (Rotation of the toy top 10) The toy top 10 is attached to a launching device (not shown). At this time, for example, the convex portion of the output rotor of the launching device is engaged with the arc-shaped concave portion formed on the top surface of the toy top 10, and the output rotor is rotated to rotate the toy top 10, and then the output rotor is stopped. This releases the engagement between the arc-shaped concave portion and the convex portion, and the toy top 10 is launched. Alternatively, the toy top 10 is held by a chuck of the launching device and rotated, and then the chuck is released, thereby launching the toy top 10.

[0025] (Movement of 10 spinning tops) As shown in Figure 5(A), the toy top 10 running around on the lower floor comes into contact with the upper corner of the stepped portion 54 at the sliding surface 19a of the climbing portion 19. In this case, if the contact force is weak, the toy top 10 will move away from the stepped portion 54 without the gear 18A and the rack 56A meshing with each other. On the other hand, when the contact force between the sliding surface 19a of the riding portion 19 and the upper corner of the step portion 54 is strong, the sliding surface 19a and the upper corner of the step portion 54 come into sliding contact with each other, and the riding portion 19 rides up on the step portion 54, as shown in Figure 5(B). This causes the ground contact portion 14a of the rotating shaft 14 to rise above the floor of the lower floor, and the gear 18A meshes with the rack 56A. As a result, the rotation of the gear 18A causes the gear 18A to roll while meshing with the rack 56A, and the movement of the toy top 10 accelerates.

[0026] Furthermore, for example, at a point where the rack 56A, with which the gear 18A engages and rolls, makes a sharp turn, a strong centrifugal force acts on the toy top 10. In this case, as shown in FIG. 5(C), the center line of the toy top 10 may be significantly tilted toward the stepped portion 54, causing the gear 18A and the rack 56A to disengage. In this case, due to the short shaft tip, the entire toy top 10 will ride up to the upper floor under the momentum of the centrifugal force / acceleration. After riding up to the upper floor, the toy top 10 will run on the floor of the upper floor and then return to the lower floor. Alternatively, the gear 18A may again engage with the rack 56A when returning to the lower floor, causing the toy top 10 to accelerate.

[0027] (Effects of the embodiment) The toy top set 100 configured in this manner can provide the following effects. First, when the toy top 10 hits the step 54, the ground contact portion 14a of the rotating shaft 14 moves around while remaining lifted from the floor of the lower floor, which creates an unexpected and highly entertaining toy top set 100. Secondly, after the toy top 10 comes into contact with the stepped portion 54, the gear 18A and the rack 56A mesh together and the toy top is rapidly accelerated, so that a highly entertaining toy top set 100 can be realized.

[0028] (Modification of shaft portion 12A) 6(A) to 6(C) are front views of modified examples of the shaft portion 12A. In the shaft portions 12B to 12D, the same parts as those of the shaft portion 12A are given the same reference numerals, and the description thereof will be omitted. The rotating shaft 14 and the ground contact portion 14a are given the same reference numerals.

[0029] 6(A), the ground contact portion 14a of the rotating shaft 14 is made of rubber, which has a higher coefficient of friction than plastic. The gear 18B is the same as the gear 18A. This shaft 12B makes it easier for the toy top 10 to run around when it rotates (spins on its axis). In the case where the ground contact portion 14a is made of rubber, if the rubber ground contact portion 14a is in contact with the floor of the lower floor during acceleration, the ground contact portion 14a will rub against the floor of the lower floor, creating a large resistance and making it difficult to accelerate. In this regard, if the ground contact portion 14a is lifted from the floor of the lower floor during acceleration, as in the embodiment, acceleration becomes easier.

[0030] 6(B) shows a shaft portion 12C in which the gear 18C is a cylindrical gear. With this shaft portion 12C, the sliding surface 19a of the run-up portion 19 abuts and slides against the floor of the upper floor of the stepped portion 54. Even in this case, when the gear 18C and the rack 56A mesh, the gear 18C rolls relative to the rack 56A, accelerating the toy top 10. However, when the gear 18C and the rack 56A do not mesh, or when the meshing between the gear 18C and the rack 56A is incomplete, the sliding contact between the sliding surface 19a of the run-up portion 19 and the floor of the upper floor of the stepped portion 54 makes it easier for the toy top 10 to run up onto the floor of the upper floor. In the case of the gear 18C, it is less likely for the gear 18C and the rack 56A to mesh with each other than with the gear 18A, making it easier for the toy top 10 to run up onto the floor of the upper floor.

[0031] 6(C) has a shaft 12C in which the gear 18D is a cylindrical gear and the ground contact portion 14a of the rotating shaft 14 is made of rubber, which has a higher coefficient of friction than plastic. This shaft 12D makes it easier for the toy top 10 to run around when it rotates (spins on its axis). In addition, since the ground contact portion 14a is lifted off the floor below during acceleration, energy loss can be reduced.

[0032] (Second embodiment) 7 is a perspective view of a second embodiment of a toy top set 200. In the toy top set 200, parts that are the same as those in the toy top set 100 are given the same reference numerals and descriptions thereof will be omitted. The toy top set 200 of the second embodiment differs from the toy top set 100 of the first embodiment in that the axle portion is different and the acceleration rail of the stadium is different. As shown in Figure 8, the shaft 12E of the toy top 10 is provided with rollers 18E instead of gears as the rotating body. The rollers 18E are tapered rollers that become larger in diameter as they go downward. The acceleration rails of the stadium 50B are rails 56B that have a smooth surface and can come into contact (engage) with the rollers 18E. This toy top set 200 can provide the same effects as the toy top set 100.

[0033] The roller 18E may be cylindrical, and the contact portion 14a of the rotary shaft 14 may be made of rubber.

[0034] (Other variations) Although the toy top set 100 according to the embodiment of the present invention has been described above, the present invention is not limited to such an embodiment or modified example. For example, in the above embodiment, the shaft portion is detachable from the body portion, but the shaft portion may be fixed to the body portion.

[0035] In the above embodiment, the raised portion is provided on the shaft portion, but the raised portion may be provided on the body portion. The raised portion may also be separate from the shaft portion or the body portion. Furthermore, the raised portion may be rotatable about the rotation axis.

[0036] Furthermore, in the above embodiment, modified examples of the shaft portion have been given, but the shaft portion may be replaceable.

[0037] Furthermore, in the above embodiment, the diameter of the run-up portion is approximately twice that of the rotating body (gear or roller), but the diameter of the expanded portion of the run-up portion may be larger than the upper end of the rotating body. Furthermore, the ease of meshing can be varied depending on the slope and diameter of the sliding surface. For example, when the slope of the sliding surface is steep, the toy top 10 will only run up when the rotational force is high and a strong centrifugal force is acting. On the other hand, when the slope is gentle, it is easy to run up, but when the diameter is large, the rotational force / centrifugal force is required to continue running up until the rotating body reaches the acceleration rail.
