Detailed Description of the Embodiments

[0009] Hereafter, a top toy set and a top toy according to embodiments of the present invention are explained based on the drawings.(First Embodiment)

[0010] FIG. 1 is a perspective view of a top toy set 100.

[0011] This top toy set 100 comprises a top toy 10, and a stadium 50A for having top toys 10 battle each other.(Top Toy 10)

[0012] FIG. 2 is a front view of the top toy 10. The top toy 10 is constituted mostly from plastic.

[0013] The top toy 10 comprises a trunk part 11 and a shaft part 12A. The trunk part 11 is a composite part. Recesses and projections are formed all around the outer periphery of the trunk part 11. The attack performance and defense performance change during battle according to the shape of these recesses and projections.

[0014] A mounting unit 13 is provided on the bottom end of the trunk part 11. The shaft part 12A is detachably mounted on the mounting unit 13.

[0015] FIG. 3 is a front view of the shaft part 12A. This shaft part 12A is provided with a rotating shaft 14. The bottom end of the rotating shaft 14 constitutes a landing part 14a.

[0016] Engaging recesses 15 are formed at prescribed intervals along the entire circumference direction area of the rotating shaft 14 on the outer periphery of the center part in the vertical direction of the rotating shaft 14. Meanwhile, as shown in FIG. 4, a hole 16 for insertion of the rotating shaft 14 is formed on the mounting unit 13. Inside the hole 16, provided are elastic claws 17 for engaging with the engaging recesses 15. Two elastic claws 17 are provided sandwiching the center axis of the hole 16. By engaging the elastic claws 17 and the engaging recesses 15, the shaft part 12A is mounted on the mounting unit 13. When the shaft part 12A is mounted in the mounting unit 13, the top end of a ride-over part 19 described later is abutted on the bottom end of the mounting unit 13. By this abutting, the shaft part 12A is held stably on the trunk part 11. The shaft part 12A rotates integrally with the trunk part 11. The shaft part 12A can be removed from the trunk part 11 by manually pulling downward with respect to the trunk part 11.

[0017] A gear 18A is provided directly above the landing part 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 gear that is tapered so that the diameter becomes larger as it goes downward.

[0018] The ride-over part 19 that protrudes in a flange shape is provided directly above the gear 18A of the rotating shaft 14 and below the engaging recesses 15. The bottom surface of the ride-over part 19 is an axially symmetrical sliding contact surface 19a in which the bottom end has the same shape as the top end circumscribed circle of the gear 18A and in which the diameter increases as it goes upward in the axial direction.(Stadium 50A)

[0019] The stadium 50A shown in FIG. 1 is constituted to be transparent using polyvinylchloride.

[0020] The stadium 50A constitutes a field for doing top battles, and comprises a base plate 51, and a cover body 52 provided on the base plate 51 and having a circular opening 52a on the ceiling. The center of the field floor surface forms a grinding bowl shaped recess 53. Also, a cant (slope) on which the top toy 10 runs around is formed on the perimeter of the recess 53. A step part 54 is formed on the outside of this cant. The field is divided into a lower level and an upper level with this step part 54 as the boundary.

[0021] The upper part of the step part 54 is constituted from an acceleration rail. The acceleration rail is constituted from a rack 56A that can mesh (engage) with the gear 18A. The rack 56A constitutes a portion of the step part 54 and constitutes a portion of the upper level.(Relationship between Shaft Part 12A and Rack 56A)

[0022] When the rack 56A and the gear 18A mesh, the landing part 14a of the rotating shaft 14 is constituted to separate from the floor of the lower level. That is, this top toy set 100 is configured so that when the top toy 10 that is running around the lower level abuts the step part 54, first, the sliding contact surface 19a of the ride-over part 19 abuts the top corner of the step part 54. By the sliding contact of the sliding contact surface 19a and the step part 54, when the ride-over part 19 rides on the step part 54, the landing part 14a of the rotating shaft 14 separates from the lower level floor, and the gear 18A meshes with the rack 56A.

[0023] Said another way, when the landing part 14a of the rotating shaft 14 does not separate from the lower level floor, the gear 18A does not mesh with the rack 56A.(Rotational Energization of Top Toy 10)

[0024] The top toy 10 is mounted on a shooting device (not illustrated). At that time, for example, the convex part of the output rotor of the shooting device is engaged with an arc-shaped recess formed on the top surface of the top toy 10, and by rotating the output rotor, the top toy 10 is rotationally energized, after which the output rotor is stopped. As a result, engagement of the arc-shaped recess and the convex part is released, and the top toy 10 is shot. Alternatively, the top toy 10 is held by a chuck of the shooting device and rotationally energized, and the top toy 10 is shot by releasing the hold by the chuck.(Movement of Top Toy 10)

[0025] As shown in FIG. 5 (A), in the top toy 10 running around the lower level, the sliding contact surface 19a of the ride-over part 19 abuts the top corner of the step part 54. In this case, if the abutting force is weak, the gear 18A and the rack 56A are left unmeshed, and the top toy 10 separates from the step part 54.

[0026] Meanwhile, when the abutting force between the sliding contact surface 19a of the ride-over part 19 and the top corner of the step part 54 is strong, as shown in FIG. 5 (B), there is sliding contact between the sliding contact surface 19a and the top corner of the step part 54, and the ride-over part 19 rides on the step part 54. As a result, the landing part 14a of the rotating shaft 14 floats up from lower level floor, and the gear 18A meshes with the rack 56A. As a result, by rotation of the gear 18A, the gear 18A rolls while meshing with the rack 56A, and the movement of the top toy 10 is accelerated.

[0027] For example, at a location where the gear 18A is meshing and rolling and the rack 56A is in a sharp curve, a strong centrifugal force works on the top toy 10. In this case, as shown in FIG. 5 (C), the center line of the top toy 10 significantly inclines to the step part 54 side, and there are cases when meshing of the gear 18A and the rack 56A is disengaged, in which case there is also an effect of the shaft tip being short, and the entire top toy 10 rides on the upper level with the momentum of the centrifugal force / acceleration as is. The top toy 10 which has ridden on the upper level returns to the lower level after running on the upper level floor. Alternatively, there are also cases when at the timing of returning to the lower level, the gear 18A and the rack 56A mesh again and the top toy 10 accelerates.(Effect of the Embodiment)

[0028] It is possible to obtain the following kind of effects according to the top toy set 100 configured in this way.

[0029] First, when the top toy 10 contacts the step part 54, it moves around with the landing part 14a of the rotating shaft 14 still floating up from the lower level floor, so there is an element of surprise, making it possible to realize a top toy set 100 that is highly entertaining.

[0030] Second, after abutting of the top toy 10 and the step part 54, the gear 18A and the rack 56A mesh and are rapidly accelerated, so it is possible to realize a top toy set 100 that is highly entertaining.(Modification Example of Shaft Part 12A)

[0031] FIG. 6 (A) to (C) are front views of modification examples of the shaft part 12A. In shaft parts 12B to 12D, the same code numbers are given to parts in common with the shaft part 12A, and explanation of those are omitted. A common code number is used for the landing part 14a of the rotating shaft 14.

[0032] In the shaft part 12B shown in FIG. 6 (A), the landing part 14a of the rotating shaft 14 is made of rubber which has a greater friction coefficient than plastic. A gear 18B is the same as the gear 18A. According to this shaft part 12B, the top toy 10 runs around more easily by rotation (autorotation) of the top toy 10.

[0033] When rubber is used for the landing part 14a, when the rubber landing part 14a lands on the lower level floor, during acceleration, the landing part 14a rubs against the lower level floor, so this leads to great resistance which makes acceleration difficult. In this regard, as in the embodiment, if the landing part 14a is floated up from the lower level floor when accelerating, acceleration becomes easier.

[0034] In a shaft part 12C shown in FIG. 6 (B), a gear 18C is a cylindrical gear. According to this shaft part 12C, the sliding contact surface 19a of the ride-over part 19 and the upper level floor of the step part 54 abut and are in sliding contact. In this case as well, when the gear 18C and the rack 56A have meshed, the gear 18C rolls with respect to the rack 56A and the top toy 10 is accelerated. However, when the gear 18C and the rack 56A do not mesh, or when meshing of the gear 18C and the rack 56A is incomplete, by sliding contact of the sliding contact surface 19a of the ride-over part 19 and the upper level floor of the step part 54, it is easier for the top toy 10 to ride onto the upper level floor. In the case of the gear 18C, compared to the case of the gear 18A, it is difficult for the gear 18C and the rack 56A to mesh, and it is easier for the top toy 10 to ride onto the upper level floor.

[0035] In the shaft part 12D shown in FIG. 6 (C), a gear 18D is a cylindrical gear, and the landing part 14a of the rotating shaft 14 is made of rubber which has a greater friction coefficient than plastic. According to this shaft part 12D, the top toy 10 runs around more easily by rotation (autorotation) of the top toy 10. The landing part 14a is floated up from the lower level floor during acceleration, so it is possible to reduce energy loss.(Second Embodiment)

[0036] FIG. 7 is a perspective view of a top toy set 200 of a second embodiment. In the top toy set 200, the same code numbers are given to parts having the same configuration as that of the top toy set 100, and an explanation of these is omitted.

[0037] The point of difference between the top toy set 200 of the second embodiment from the top toy set 100 of the first embodiment is that the shaft part is different, and the acceleration rail of the stadium is different.

[0038] As shown in FIG. 8, a shaft part 12E of the top toy 10 is provided with a roller 18E instead of a gear as the rotor. The roller 18E is a roller that is tapered to have a larger diameter is it goes downward. The acceleration rail of a stadium 50B has a smooth surface and is a rail 56B that can abut (engage) with the roller 18E.

[0039] According to this top toy set 200, it is possible to obtain the same effects as with the top toy set 100.

[0040] The shape of the roller 18E can be made to be a cylindrical shape, and the landing part 14a of the rotating shaft 14 can be rubber.(Other Modification Examples)

[0041] Above, we explained the top toy set 100 according to embodiments of the present invention, but the present invention is not limited to these embodiments and modification examples.

[0042] For example, with the abovementioned embodiments, the shaft part was detachable with respect to the trunk part, but the shaft part may also be fixed to the trunk part.

[0043] In the abovementioned embodiments, the ride-over part was provided on the shaft part, but the ride-over part may also be provided on the trunk part. The ride-over part may also be a separate body from the shaft part or the trunk part. Furthermore, the ride-over part may also freely rotate with respect to the rotating shaft.

[0044] In the abovementioned embodiments, modification examples of the shaft part were cited, but it is also possible to have the shaft parts be replaceable.

[0045] In the abovementioned embodiments, the diameter of the ride-over part is approximately 2 times that of the rotor (gear or roller), but it is sufficient to have the ride-over part have the diameter of the expansion part be greater than the top end part of the roller. Furthermore, it is possible to make a difference in the ease of meshing by the slope of the sliding contact surface and the size of the diameter. For example, when the slope of the sliding contact surface is steep, the rotation force of the top toy 10 is high, and riding on only occurs when the centrifugal force acts strongly. Meanwhile, when the slope is gentle riding on is easy, but when the diameter is large, rotation force / centrifugal force is required to continue riding until the rotor reaches the acceleration rail.Explanation of Codes

Detailed Description of the Embodiments

[0009] Hereafter, a top toy set and a top toy according to embodiments of the present invention are explained based on the drawings.(First Embodiment)

[0010] FIG. 1 is a perspective view of a top toy set 100.

[0011] This top toy set 100 comprises a top toy 10, and a stadium 50A for having top toys 10 battle each other.(Top Toy 10)

[0012] FIG. 2 is a front view of the top toy 10. The top toy 10 is constituted mostly from plastic.

[0013] The top toy 10 comprises a trunk part 11 and a shaft part 12A. The trunk part 11 is a composite part. Recesses and projections are formed all around the outer periphery of the trunk part 11. The attack performance and defense performance change during battle according to the shape of these recesses and projections.

[0014] A mounting unit 13 is provided on the bottom end of the trunk part 11. The shaft part 12A is detachably mounted on the mounting unit 13.

[0015] FIG. 3 is a front view of the shaft part 12A. This shaft part 12A is provided with a rotating shaft 14. The bottom end of the rotating shaft 14 constitutes a landing part 14a.

[0016] Engaging recesses 15 are formed at prescribed intervals along the entire circumference direction area of the rotating shaft 14 on the outer periphery of the center part in the vertical direction of the rotating shaft 14. Meanwhile, as shown in FIG. 4, a hole 16 for insertion of the rotating shaft 14 is formed on the mounting unit 13. Inside the hole 16, provided are elastic claws 17 for engaging with the engaging recesses 15. Two elastic claws 17 are provided sandwiching the center axis of the hole 16. By engaging the elastic claws 17 and the engaging recesses 15, the shaft part 12A is mounted on the mounting unit 13. When the shaft part 12A is mounted in the mounting unit 13, the top end of a ride-over part 19 described later is abutted on the bottom end of the mounting unit 13. By this abutting, the shaft part 12A is held stably on the trunk part 11. The shaft part 12A rotates integrally with the trunk part 11. The shaft part 12A can be removed from the trunk part 11 by manually pulling downward with respect to the trunk part 11.

[0017] A gear 18A is provided directly above the landing part 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 gear that is tapered so that the diameter becomes larger as it goes downward.

[0018] The ride-over part 19 that protrudes in a flange shape is provided directly above the gear 18A of the rotating shaft 14 and below the engaging recesses 15. The bottom surface of the ride-over part 19 is an axially symmetrical sliding contact surface 19a in which the bottom end has the same shape as the top end circumscribed circle of the gear 18A and in which the diameter increases as it goes upward in the axial direction.(Stadium 50A)

[0019] The stadium 50A shown in FIG. 1 is constituted to be transparent using polyvinylchloride.

[0020] The stadium 50A constitutes a field for doing top battles, and comprises a base plate 51, and a cover body 52 provided on the base plate 51 and having a circular opening 52a on the ceiling. The center of the field floor surface forms a grinding bowl shaped recess 53. Also, a cant (slope) on which the top toy 10 runs around is formed on the perimeter of the recess 53. A step part 54 is formed on the outside of this cant. The field is divided into a lower level and an upper level with this step part 54 as the boundary.

[0021] The upper part of the step part 54 is constituted from an acceleration rail. The acceleration rail is constituted from a rack 56A that can mesh (engage) with the gear 18A. The rack 56A constitutes a portion of the step part 54 and constitutes a portion of the upper level.(Relationship between Shaft Part 12A and Rack 56A)

[0022] When the rack 56A and the gear 18A mesh, the landing part 14a of the rotating shaft 14 is constituted to separate from the floor of the lower level. That is, this top toy set 100 is configured so that when the top toy 10 that is running around the lower level abuts the step part 54, first, the sliding contact surface 19a of the ride-over part 19 abuts the top corner of the step part 54. By the sliding contact of the sliding contact surface 19a and the step part 54, when the ride-over part 19 rides on the step part 54, the landing part 14a of the rotating shaft 14 separates from the lower level floor, and the gear 18A meshes with the rack 56A.

[0023] Said another way, when the landing part 14a of the rotating shaft 14 does not separate from the lower level floor, the gear 18A does not mesh with the rack 56A.(Rotational Energization of Top Toy 10)

[0024] The top toy 10 is mounted on a shooting device (not illustrated). At that time, for example, the convex part of the output rotor of the shooting device is engaged with an arc-shaped recess formed on the top surface of the top toy 10, and by rotating the output rotor, the top toy 10 is rotationally energized, after which the output rotor is stopped. As a result, engagement of the arc-shaped recess and the convex part is released, and the top toy 10 is shot. Alternatively, the top toy 10 is held by a chuck of the shooting device and rotationally energized, and the top toy 10 is shot by releasing the hold by the chuck.(Movement of Top Toy 10)

[0025] As shown in FIG. 5 (A), in the top toy 10 running around the lower level, the sliding contact surface 19a of the ride-over part 19 abuts the top corner of the step part 54. In this case, if the abutting force is weak, the gear 18A and the rack 56A are left unmeshed, and the top toy 10 separates from the step part 54.

[0026] Meanwhile, when the abutting force between the sliding contact surface 19a of the ride-over part 19 and the top corner of the step part 54 is strong, as shown in FIG. 5 (B), there is sliding contact between the sliding contact surface 19a and the top corner of the step part 54, and the ride-over part 19 rides on the step part 54. As a result, the landing part 14a of the rotating shaft 14 floats up from lower level floor, and the gear 18A meshes with the rack 56A. As a result, by rotation of the gear 18A, the gear 18A rolls while meshing with the rack 56A, and the movement of the top toy 10 is accelerated.

[0027] For example, at a location where the gear 18A is meshing and rolling and the rack 56A is in a sharp curve, a strong centrifugal force works on the top toy 10. In this case, as shown in FIG. 5 (C), the center line of the top toy 10 significantly inclines to the step part 54 side, and there are cases when meshing of the gear 18A and the rack 56A is disengaged, in which case there is also an effect of the shaft tip being short, and the entire top toy 10 rides on the upper level with the momentum of the centrifugal force / acceleration as is. The top toy 10 which has ridden on the upper level returns to the lower level after running on the upper level floor. Alternatively, there are also cases when at the timing of returning to the lower level, the gear 18A and the rack 56A mesh again and the top toy 10 accelerates.(Effect of the Embodiment)

[0028] It is possible to obtain the following kind of effects according to the top toy set 100 configured in this way.

[0029] First, when the top toy 10 contacts the step part 54, it moves around with the landing part 14a of the rotating shaft 14 still floating up from the lower level floor, so there is an element of surprise, making it possible to realize a top toy set 100 that is highly entertaining.

[0030] Second, after abutting of the top toy 10 and the step part 54, the gear 18A and the rack 56A mesh and are rapidly accelerated, so it is possible to realize a top toy set 100 that is highly entertaining.(Modification Example of Shaft Part 12A)

[0031] FIG. 6 (A) to (C) are front views of modification examples of the shaft part 12A. In shaft parts 12B to 12D, the same code numbers are given to parts in common with the shaft part 12A, and explanation of those are omitted. A common code number is used for the landing part 14a of the rotating shaft 14.

[0032] In the shaft part 12B shown in FIG. 6 (A), the landing part 14a of the rotating shaft 14 is made of rubber which has a greater friction coefficient than plastic. A gear 18B is the same as the gear 18A. According to this shaft part 12B, the top toy 10 runs around more easily by rotation (autorotation) of the top toy 10.

[0033] When rubber is used for the landing part 14a, when the rubber landing part 14a lands on the lower level floor, during acceleration, the landing part 14a rubs against the lower level floor, so this leads to great resistance which makes acceleration difficult. In this regard, as in the embodiment, if the landing part 14a is floated up from the lower level floor when accelerating, acceleration becomes easier.

[0034] In a shaft part 12C shown in FIG. 6 (B), a gear 18C is a cylindrical gear. According to this shaft part 12C, the sliding contact surface 19a of the ride-over part 19 and the upper level floor of the step part 54 abut and are in sliding contact. In this case as well, when the gear 18C and the rack 56A have meshed, the gear 18C rolls with respect to the rack 56A and the top toy 10 is accelerated. However, when the gear 18C and the rack 56A do not mesh, or when meshing of the gear 18C and the rack 56A is incomplete, by sliding contact of the sliding contact surface 19a of the ride-over part 19 and the upper level floor of the step part 54, it is easier for the top toy 10 to ride onto the upper level floor. In the case of the gear 18C, compared to the case of the gear 18A, it is difficult for the gear 18C and the rack 56A to mesh, and it is easier for the top toy 10 to ride onto the upper level floor.

[0035] In the shaft part 12D shown in FIG. 6 (C), a gear 18D is a cylindrical gear, and the landing part 14a of the rotating shaft 14 is made of rubber which has a greater friction coefficient than plastic. According to this shaft part 12D, the top toy 10 runs around more easily by rotation (autorotation) of the top toy 10. The landing part 14a is floated up from the lower level floor during acceleration, so it is possible to reduce energy loss.(Second Embodiment)

[0036] FIG. 7 is a perspective view of a top toy set 200 of a second embodiment. In the top toy set 200, the same code numbers are given to parts having the same configuration as that of the top toy set 100, and an explanation of these is omitted.

[0037] The point of difference between the top toy set 200 of the second embodiment from the top toy set 100 of the first embodiment is that the shaft part is different, and the acceleration rail of the stadium is different.

[0038] As shown in FIG. 8, a shaft part 12E of the top toy 10 is provided with a roller 18E instead of a gear as the rotor. The roller 18E is a roller that is tapered to have a larger diameter is it goes downward. The acceleration rail of a stadium 50B has a smooth surface and is a rail 56B that can abut (engage) with the roller 18E.

[0039] According to this top toy set 200, it is possible to obtain the same effects as with the top toy set 100.

[0040] The shape of the roller 18E can be made to be a cylindrical shape, and the landing part 14a of the rotating shaft 14 can be rubber.(Other Modification Examples)

[0041] Above, we explained the top toy set 100 according to embodiments of the present invention, but the present invention is not limited to these embodiments and modification examples.

[0042] For example, with the abovementioned embodiments, the shaft part was detachable with respect to the trunk part, but the shaft part may also be fixed to the trunk part.

[0043] In the abovementioned embodiments, the ride-over part was provided on the shaft part, but the ride-over part may also be provided on the trunk part. The ride-over part may also be a separate body from the shaft part or the trunk part. Furthermore, the ride-over part may also freely rotate with respect to the rotating shaft.

[0044] In the abovementioned embodiments, modification examples of the shaft part were cited, but it is also possible to have the shaft parts be replaceable.

[0045] In the abovementioned embodiments, the diameter of the ride-over part is approximately 2 times that of the rotor (gear or roller), but it is sufficient to have the ride-over part have the diameter of the expansion part be greater than the top end part of the roller. Furthermore, it is possible to make a difference in the ease of meshing by the slope of the sliding contact surface and the size of the diameter. For example, when the slope of the sliding contact surface is steep, the rotation force of the top toy 10 is high, and riding on only occurs when the centrifugal force acts strongly. Meanwhile, when the slope is gentle riding on is easy, but when the diameter is large, rotation force / centrifugal force is required to continue riding until the rotor reaches the acceleration rail.Explanation of Codes
