[0019] Hereafter, a top toy according to an embodiment is explained based on drawings.

[0020] FIG. 1 is a perspective view of a top toy 10 of the embodiment.

[0021] This top toy 10 is used for a top battle, for example. In the battle, for example, a plurality (normally two) of top toys 10 released into a field 91 (FIG. 10) of a stadium 90 are collided with each other, and the top toy 10 winner is determined as a result.

[0022] A rotation shaft 11 of the top toy 10 is constituted from a thick shaft 11a and a thin shaft 11b, and for example, it is possible for the thin shaft 11b to be in a projecting state or a non-projecting state with reference to the bottom surface of the thick shaft 11a according to the centrifugal force accompanying the rotational force of the top toy 10.

[0023] The top toy 10 is rotationally energized by a launcher 80 (FIG. 9), and shot into the field 91 which is a concave curved surface of the stadium 90.

[0024] As an example, in the early stage of a battle when the centrifugal force accompanying the rotational force of the top toy 10 is large, the thin shaft 11b contacts the field 91, and the top toy 10 mainly does battle near the center of the field 91.

[0025] When the top toy 10 reaches mid-battle when the rotational force of the top toy 10 has weakened and the centrifugal force has decreased to a degree, the thin shaft 11b retreats from the bottom surface of the thick shaft 11a, and the thick shaft 11a contacts the field 91. As a result, movement of the top toy 10 is accelerated, and the top toy 10 moves around a lot on the field 91 (one-stage acceleration). As a result, the frequency of the top toy 10 abutting an external rack 93 increases, the movement of the top toy 10 is further accelerated by the external rack 93 (two-stage acceleration), and the battle is performed using the entire field 91 of the stadium 90.

[0026] When the end of the battle in which the rotational force of the top toy 10 weakens greatly is reached, the range in which the top toy 10 moves around becomes smaller, and a relatively calm battle is performed near the center of the field 91.

[0027] As described above, with the top toy 10 according to the embodiment, it is possible to greatly change the mode of battle especially in mid-battle in a way that did not exist before. For example, after the rotational force of the top toy 10 has decreased, conversely, it possible to provide unpredictability of increasing the attack power by increasing the frequency of acceleration using the external rack 93. If the shooting force (centrifugal force) by the launcher 80 is weakly controlled, and shooting is done when the thin shaft 11b is in the non-projecting state from the bottom surface of the thick shaft 11a, at the early stage of the battle, the top toy 10 meshes with the external rack 93 at a high frequency and is made to move around a lot, making it possible to enhance tactical strategy.Top Toy 10

[0028] FIG. 2 is an exploded perspective view of the top toy 10.

[0029] The top toy 10 is constituted from a trunk part 10a that constitutes the upper structure, and a shaft part 10b that constitutes the lower structure. This top toy 10 is constituted mostly from hard plastic, with metal used in appropriate places. Metal components will be mentioned as appropriate, but the invention is not limited to this.Trunk Part 10a

[0030] The trunk part 10a is constituted as a composite component in which a plurality of components are joined. The composite component includes a flywheel made of metal, for example. Recesses and projections are formed on the outer circumference of the trunk part 10a, and the offense and defense performance of the top toy 10 changes according to the size, shape, and arrangement of the recesses and projections. The trunk part 10a here is constituted as a trunk part for clockwise rotation, but it may also be a trunk part for counterclockwise rotation or a trunk part for both rotations.

[0031] As another example, three arc-shaped grooves 100 of the same size are formed at equal intervals along the circumferential direction on the top surface of the trunk part 10a. The three arc-shaped grooves 100 are used for rotationally energizing the top toy 10 by the launcher 80.

[0032] FIG. 3 is a bottom perspective view of the trunk part 10a.

[0033] A hanging wall 101 that includes an arc-shaped wall portion that is centered on the center line of the trunk part 10a is provided on the bottom surface of the trunk part 10a, and an eave-shaped outward engaging piece 102 is provided on the lower end of the hanging wall 101. Two outward engaging pieces 102 are formed to have two-fold symmetry with respect to the center line of the trunk part 10a. However, the number of outward engaging pieces 102 is not limited to being two.Shaft Part 10b

[0034] FIG. 4 is an exploded perspective view of the shaft part 10b.

[0035] The shaft part 10b is constituted including the rotation shaft 11, and a shaft support 12 that supports the rotation shaft 11. The shaft part 10b has a shape that is compatible with either a top toy 10 for clockwise rotation or for counterclockwise rotation.A. Shaft Support 12

[0036] The shaft support 12 comprises an upper plate 120 and a lower frame 121 that are joined to each other and form an interior space. The upper plate 120 and the lower frame 121 are joined by being screwed using a male screw 122.

[0037] An arc-shaped standing wall 123 centered on the center line of the trunk part 10a is provided on the top surface of the upper plate 120, and an eave-shaped inward engaging piece 124 is formed on the top end of the standing wall 123. This inward engaging piece 124 is formed one each corresponding respectively to the abovementioned two outward engaging pieces 102. This inward engaging piece 124 engages with the outward engaging piece 102 by the corresponding outward engaging piece 102 entering in at the underside from one direction. The entering direction of the outward engaging piece is different when attaching the trunk part for counterclockwise rotation, and when attaching the trunk part for clockwise rotation.

[0038] An abutting plate 125 is provided so as to cross between two inward engaging pieces 124 on the top surface of the upper plate 120. The abutting plate 125 is used for abutting with the bottom surface of the trunk part 10a when joining the trunk part 10a and the shaft part 10b. One each of an insertion piece 126 is vertically installed at a position corresponding to each inward engaging piece 124 on the abutting plate 125. The abutting plate 125 is joined to the lower frame 121 sandwiching the upper plate 120 by screwing using a male screw 127 in a state with the insertion piece 126 inserted in a hole (not illustrated) on the top surface of the upper plate 120.

[0039] A passage for the hanging wall 101 is formed in the gap between the abutting plate 125 and each inward engaging piece 124. Specifically, in a state with the bottom surface of the trunk part 10a and the top surface of the abutting plate 125 of the shaft part 10b abutting from the axial direction, when the trunk part 10a is relatively rotated with respect to the shaft part 10b, the arc-shaped wall portion oof the hanging wall 101 can pass through the gap between the abutting plate 125 and each inward engaging piece 124.

[0040] Elastic locking protrusions 128a, 128b are formed on both sides of each insertion piece 126 on the abutting plate 125.

[0041] By relatively rotating the trunk part 10a counterclockwise with respect to the shaft part 10b, when the outward engaging piece 102 of the trunk part 10a for clockwise rotation is engaged with the inward engaging piece 124, of these, the elastic locking protrusion 128a is elastically locked to a corner part a (FIG. 3) of the outward engaging piece 102, holding the outward engaging piece 102 and the inward engaging piece 124 in an engaged state. By this holding, the trunk part 10a is joined to the shaft part 10b. Holding of the engagement of the outward engaging piece 102 and the inward engaging piece 124 is released when a relative counterclockwise rotational force acts on the shaft part 10b when there is a collision, etc. between top toys, and eventually, the engagement of the outward engaging piece 102 and the inward engaging piece 124 is released, and the trunk part 10a and the shaft part 10b are disassembled.

[0042] Meanwhile, when the outward engaging piece of the trunk part for counterclockwise rotation is engaged with the inward engaging piece 124 by relatively rotating the trunk part counterclockwise with respect to the shaft part 10b, the elastic locking protrusion 128b is elastically locked to the corner part of the outward engaging piece, and the engaged state of the outward engaging piece and the inward engaging piece 124 is held. By this holding, the trunk part is joined to the shaft part 10b. The holding of the engagement between the outward engaging piece and the inward engaging piece 124 is released when a relative clockwise rotational force acts on the shaft part 10b when there is a collision, etc., between top toys, and eventually, the engagement of the outward engaging piece and the inward engaging piece 124 is released, and the trunk part and the shaft part 10b are disassembled.B. Rotation Shaft 11

[0043] FIG. 5 is an exploded perspective view showing the attachment structure of the rotation shaft 11.

[0044] The rotation shaft 11 is attached to the shaft support 12. The rotation shaft 11 is constituted from the thick shaft 11a having a large ground contact part diameter, and the thin shaft 11b having a small ground contact part diameter.

[0045] A through hole 110 is formed on the thick shaft 11a and penetrates vertically along the center line thereof, and the thin shaft 11b is stored inside the through hole 110.

[0046] Also, preferably, a gear 111 is formed on the outer circumference of the thick shaft 11a. The gear 111 is able to mesh with the external rack 93 described later. Also, preferably, a taper that narrows facing downward is given to the lower end part of the gear 111, and the lower end of the gear 111 may be flush with the bottom surface of the thick shaft 11a. As a result, the outer edge of the thick shaft 11a may be a wave shape. In this way, by having the outer edge of the thick shaft 11a have a wave shape, it is easier to more strongly kick the field 91 which is a concave curved surface. Thus, when the thick shaft 11a touches ground, it is easier for the top toy 10 to reach the external rack 93, and it is possible to increase the frequency of acceleration by the external rack 93. Also, preferably, by having the gear 111 and the outer edge of the thick shaft 11a be integrated, it is possible to use a simple structure.

[0047] Also, preferably, a ring plate 112 is attached on a step part (portion in which the diameter changes in steps) of the outer circumference of the thick shaft 11a. Also, the thick shaft 11a is inserted through a through hole 121a of the lower frame 121, and one surface of this ring plate 112 abuts the step provided on the outer circumference of the thick shaft 11a, and the other surface abuts an edge 121b of the through hole 121a. In this way, by providing a step on the outer circumference of the thick shaft 11a, it is possible to prevent coming out downward from the lower frame 121.

[0048] FIG. 6 is an exploded perspective view of the periphery of the thin shaft 11b.

[0049] The thin shaft 11b has a shaft tip that is sharp, and a mountain-shaped sliding contact part 113 with a triangular roof shape having a larger area than the thin shaft 11b is provided on the top end part. This thin shaft 11b, in a state inserted from above in an upper ring plate 114, a coil spring 115, and a lower ring plate 116, is stored in the through hole 110 of the thick shaft 11a. At that time, the step provided on the outer circumference of the thin shaft 11b abuts the edge (not illustrated) of the through hole 110 via the lower ring plate 116, preventing coming out downward from the thick shaft 11a. In this state, it is preferable that the thin shaft 11b and the thick shaft 11a be one component (composite component), and be assembled together with the shaft support 12. This allows the thick shaft 11a to be easily removed, and prevents the the thin shaft 11b from being greatly exposed and damaged.

[0050] The thin shaft 11b and the thick shaft 11a are attached to the shaft support 12 in a form with the upper part pressed down by two movable members 13 described later. At that time, the thick shaft 11a is fixed by the lower ring plate 116 abutting the edge of the through hole 110 by the energizing force of the coil spring 115.

[0051] A wave-shaped outer circumference surface 118 of the upper outer circumference of the thick shaft 11a abuts the elastic insertion piece 126. As a result, the clutch mechanism is constituted between the wave-shaped outer circumference surface 118 and the insertion piece 126, and for example, when an impact of a certain level or greater acts on the thick shaft 11a, the thick shaft 11a rotates relatively with respect to the thin shaft 11b. In specific terms, when the top toy 10 strongly contacts the external rack 93 described later, the thick shaft 11a rotates relatively with respect to the thin shaft 11b and mitigates the impact, making it easy for the external rack 93 and the gear 111 to mesh. There is rotational resistance during relative rotation using a sliding clutch mechanism, and it is easier for the outer edge of the thick shaft 11a to kick the field 91 which is a concave curved surface.C. Thin Shaft Operating Mechanism

[0052] Two movable members 13 capable of reciprocating motion in substantially the radial direction of the thin shaft 11b are provided on the lower frame 121. The movable members 13 may be made of any material, such as resin, metal, etc. The two movable members 13 are each able to operate facing radially outward when centrifugal force acts accompanying the rotation of the top toy 10. On each movable member 13 is formed an inverted V-shaped recess (valley-shaped locked part) 130 having a complementary shape with the abovementioned mountain-shaped sliding contact part (mountain-shaped locking part) 113. This inverted V-shaped recess 130, in a state with the top toy 10 not rotating, is perfectly fitted with the inverted V-shaped recess 130 by the energizing force of the coil spring 115.

[0053] FIGS. 7 and FIG. 8 are front views for explaining the operation of the movable members 13.

[0054] When the centrifugal force that acts on the two movable members 13 by rotation of the top toy 10 increases, each of the two movable members 13 operates facing radially outward. At this time, the inverted V-shaped recess 130 of the two movable members 13 is in sliding contact with the mountain-shaped sliding contact part 113 of the thin shaft 11b and the thin shaft 11b is pressed downward. As a result, the thin shaft 11b projects from the thick shaft 11a.

[0055] Meanwhile, when the rotation of the top toy 10 weakens and the centrifugal force acting on the two movable members 13 decreases, the inverted V-shaped recess 130 of the two movable members 13 is put in sliding contact with the mountain-shaped sliding contact part 113 of the thin shaft 11b by the energizing force of the coil spring 115, and each of the two movable members 13 operate facing radially inward. As a result, the thin shaft 11b is withdrawn inside the thick shaft 11a.Launcher 80

[0056] FIG. 9 is a perspective view showing the launcher 80.

[0057] The launcher 80 comprises a top holder 81 that holds the rotationally energized top toy 10. The top holder 81 is provided with the same number of insertion pieces 81a corresponding to the arc-shaped groove 100 of the top toy 10. A locked part 81b that projects in the rotationally energized direction is formed on the insertion piece 81a. After the insertion piece 81a is inserted in the arc-shaped groove 100 of the trunk part 10a, the top toy 10 is rotated relatively in the direction opposite to the rotationally energized direction of the top toy 10 with respect to the top holder 81, and by the locked part 81b getting under the edge wall of one end part of the arc-shaped groove 100, the top toy 10 is attached to the top holder 81.

[0058] A handle 82 is provided on the launcher 80, and one end of a cord (not illustrated) is attached to this handle 82. The cord is wound on an input rotor (not illustrated) by the restoring force of a mainspring, and by operating the handle 82 to pull the cord, rotational force is inputted to the input rotor. The input rotor is coupled to the top holder 81, and is rotated by the rotation of the input rotor.

[0059] With this launcher 80, the top toy 10 attached to the top holder 81 is rotationally energized by rotating the top holder 81 by operating the handle 82. When operation of the handle 82 is stopped, while rotation of the top holder 81 stops, the top toy 10 continues rotating due to inertial force, so the locked part 81b comes out from under the edge wall of one end part in the arc-shaped groove 100, and is pushed out by sliding contact with the inclined surface of the back of the insertion piece 81a, and the top toy 10 is shot.

[0060] Here, the input rotor coupled to the top holder 81 was rotated using a cord, but it is also possible to use a gear for the input rotor coupled to the top holder 81, with the gear rotated by a rack belt having a belt part on which a rack is formed.Stadium 90

[0061] FIG. 10 is a perspective view showing the external appearance of the stadium 90.

[0062] The bottom surface of the field 91 of the stadium 90 is a concave curved surface, and the field 91 is covered by a transparent cover 92 with an open center. The external rack 93 on which are formed teeth that mesh with the gear 111 of the top toy 10 that moves around inside the field 91 is arranged in the field 91.

[0063] With this stadium 90, by meshing the gear 111 of the top toy 10 and the external rack 93, the top toy 10 is rolled with respect to the external rack 93, and it is possible to increase the speed at which the top toy 10 moves around.How to Play, and Operation of Top Toy 10

[0064] Next, an example of how to play is explained together with operation of the top toy 10.

[0065] After mounting the top toy 10 on the launcher 80, the launcher 80 is moved above the stadium 90, and the cord is pulled strongly. Having done that, the top toy 10 rotates (autorotates) with respect to the launcher 80, and a large centrifugal force acts on the movable members 13 inside the top toy 10. As a result, the movable members 13 move to the outside of the top toy 10, and the thin shaft 11b projects downward from the bottom surface of the thick shaft 11a.

[0066] When the cord is fully pulled, while rotation of the top holder 81 stops, the top toy 10 tries to continue rotating due to inertia. As a result, engagement of the top toy 10 and the insertion piece 81a is released. The top toy 10 is in sliding contact with the inclined surface of the insertion piece 81a, the top toy 10 is released below the insertion piece 81a, and rides on the field 91 of the stadium 90.

[0067] In the early stage of battle, because the rotational force of the top toy 10 is large, a large centrifugal force continues to act on the movable members 13 inside the top toy 10, the thin shaft 11b maintains a projecting state downward from the bottom surface of the thick shaft 11a, and the lower end of the thin shaft 11b contacts the field 91.

[0068] In this state, because the thin shaft 11b with a small ground contact part diameter contacts the field 91 and the kicking power is small, the top toy 10 does battle near the center of the field 91. When the top toy 10 collides with another top toy 10 in a battle, it is repelled by the other top toy 10, moves around near the center of the field 91, and again returns to the center of the field 91 to do battle.

[0069] Also, when the top toy 10 reaches mid-battle when the rotational force of the top toy 10 has weakened and the centrifugal force decreases to a degree, the movable members 13 return to the initial position by the energizing force of the coil spring 115, the thin shaft 11b retreats from the bottom surface of the thick shaft 11a, and the thick shaft 11a contacts the field 91. The ground contact part diameter of the thick shaft 11a is large and the kicking force is large, so movement of the top toy 10 is accelerated (one-stage acceleration), and the top toy 10 moves around on the field 91. As a result, the frequency of the top toy 10 abutting the external rack 93 increases, the movement of the top toy 10 is further accelerated by the external rack 93 (two-stage acceleration), and it moves around a lot inside the field 91 of the stadium 90, and a dynamic battle unfolds.

[0070] Also, when the end of the battle is reached and the rotational force of the top toy 10 greatly weakens, the kicking force for the field 91 also declines according to the rotational force, so the range in which the top toy 10 moves around becomes smaller, and a relatively calm battle is performed near the center of the field 91.

[0071] If the centrifugal force acting on the movable members 13 of the top toy 10 is controlled by limiting the pulling speed of the handle 82 of the launcher 80, it is possible to shoot with the thin shaft 11b in a withdrawn state in the early stage of battle, so it is possible to mesh the top toy 10 with the external rack 93 at a high frequency so it moves around a lot, enhancing tactical strategy.Effect of Top Toy 10 According to the Embodiment

[0072] With the top toy 10 according to the embodiment described above, it is possible to achieve the main effects as noted hereafter.

[0073] With the top toy 10 according to the embodiment, initially the thin shaft 11b is projected from the thick shaft 11a, so in the early stage of battle, the battle unfolds near the center of the field 91, and when mid-battle is reached, it is possible to have a dynamic battle unfold using the entire field 91.

[0074] Meanwhile, by controlling the pulling speed of the cord of the launcher 80, by having the thick shaft 11a touch ground on the field 91 from the early stage of the battle, the choice to unfold a dynamic battle from the start is provided, making it possible to enhance strategy.Modification Examples

[0075] Above, an embodiment of the present invention was explained, but the present invention is not limited to this embodiment, and it goes without saying that various modifications are possible.

[0076] For example, in the abovementioned embodiment, the top toy 10 was rotationally energized by locking a locked part of the launcher 80 to a locking part inside the arc-shaped groove 100 provided in the trunk part 10a, but it is also possible to rotationally energize the top toy 10 using the gear 111. However, in this case, it is preferable to fix the thick shaft 11a to which the gear 111 is attached on the shaft support 12.

[0077] In the abovementioned embodiment, the gear 111 and the thick shaft 11a were configured integrally, but it is also possible to relatively rotate the gear 111 with respect to the thick shaft 11a.

[0078] In the abovementioned embodiment, when the centrifugal force was increased, the thin shaft 11b was projected from the bottom surface of the thick shaft 11a, and when the centrifugal force was decreased, the thin shaft 11b was made to be withdrawn from the bottom surface of the thick shaft 11a, but the reverse is also possible. It is also possible to configure so that the thin shaft 11b can be locked in a projecting state and a non-projecting state without regard to centrifugal force. It is also possible to have the thin shaft 11b periodically project and withdraw using an actuator, controlling from outside by remote control.Effect

[0079] According to the present invention, a thin shaft can be in a projecting state and a non-projecting state with reference to the bottom surface of a thick shaft, and a gear that can mesh with an external rack is provided on the thick shaft, so it is possible to change the mesh mode with the external rack without exchanging the rotation shaft.
