SUMMARY

Problems the Invention is Intended to Solve

In the abovementioned top toy, in addition to the user being able to change the position at which the accessory component is attached in the axial direction, there is an energizing member such as a coil spring, etc., inside, and by the coil spring being released when the top toy receives an impact, the height of the top toy in the axial direction changes to a heightening direction.

However, changing the top toy height to the lowering direction could only be performed manually by the user, and the height could not be freely changed.

The purpose of the present disclosure is to provide a top toy in which the height of the top toy can be changed to either the high direction or the low direction with a simple configuration.

Means for Solving the Problems

A top toy includes a trunk part and a shaft. The shaft has first and second engagement parts on an outer periphery thereof. The shaft extends in an axial direction. The trunk part has a shaft hole formed in a rotational center thereof. The shaft is inserted in the shaft hole when the shaft is assembled with the trunk part. The trunk part includes a first claw in the shaft hole. The second engagement part is configured lower than the first engagement part in the axial direction. The first claw projects inside the shaft hole, and is configured to selectively lock with the first engagement part or the second engagement part by a prescribed urging force. The trunk part and the shaft are engaged when the first claw is locked with either the first engagement part or the second engagement part.

DETAILED DESCRIPTION OF THE PREFERRED

One embodiment of the top toy according to an embodiment is explained while referring to FIG. 1 to FIG. 18.

A top toy 100 shown in the embodiment is used for top battles in which top toys 100 are fought by colliding with each other, for example. FIG. 1 is a perspective view of the top toy 100 of the embodiment. FIG. 2 is a perspective view showing the disassembly state of the stop toy 100 during a top battle. As shown in FIG. 1, this top toy 100 is provided with a trunk part 10 configured including an upper trunk part 11 and a lower trunk part assembly 12, and a shaft in rod form (rod-shaped shaft) 20. This top toy 100 can be disassembled into a plurality of items as a result of a top battle. For example, in the example shown in FIG. 2, as a result of a top battle, the top toy 100 is disassembled into two parts, the upper trunk part 11, and the lower trunk part assembly 12 and the shaft 20. The method of disassembly of the top toy 100 is not limited to the shown example, and for example, there can be disassembly to a finer level, such as the lower trunk part assembly 12 and the shaft 20 also being disassembled, etc. By exchanging the shaft 20, it is possible to change the level of difficulty (rotational resistance) of disassembling the top toy 100 during a top battle.

Top Toy 100

FIG. 3 is an exploded perspective view of the top toy 100.

The top toy 100 includes the trunk part 10 and the shaft 20, and is constituted mostly from plastic. A shaft hole is formed at the rotational center of the top toy 100 in the trunk part 10, and the shaft 20 is inserted into the shaft hole in the assembled state. The shaft hole includes an insertion hole 15b described later.

Upper Trunk Part 11

FIG. 4 is a perspective view of the upper trunk part 11 seen from below.

Though not particularly limited, the upper trunk part 11 is a composite configured by assembling a plurality of components. The upper trunk part 11 includes a flywheel made of metal, for example.

Though not particularly limited, the top surface of the upper trunk part 11 is flat. Inside of the outer periphery of this top surface, two arc-shaped grooves 11a that extend concentrically with the shaft 20 are formed at prescribed intervals in the circumferential direction. However, the number is not limited to being two. As described later, the arc-shaped grooves 11a are used when the top toy 100 is rotationally energized.

At the lower side center of the upper trunk part 11, a fitting hole 11b is formed for fitting a shaft head 21 of the shaft 20. The fitting hole 11b is approximately a circular hole, for example, and recesses and projections are formed at approximately equal intervals along the circumferential direction. The shape of the fitting hole 11b is not limited to the example in the drawing. For example, the fitting hole 11b may also be a polygonal hole. The part (cylindrical portion) forming this fitting hole 11b is rotatable around the shaft 20 with respect to the upper trunk part 11. Furthermore, on the lower side of the upper trunk part 11, a butterfly-shaped fitting wall 11d is erected to surround the fitting hole 11b. At least a portion of an upper plate 14 (see FIG. 5) is fitted in the fitting wall 11d. On the outside of this fitting wall 11d, joining pieces 11e that are used when joining the upper trunk part 11 with the lower trunk part assembly 12 are formed.

This upper trunk part 11 is for clockwise rotation, but by changing the formation position of the joining pieces 11e, it can be for counterclockwise rotation.

Lower Trunk Part Assembly 12

FIG. 5 is an exploded perspective view of the lower trunk part assembly 12, and FIG. 6 is a perspective view of the lower trunk part assembly 12 seen from below.

The lower trunk part assembly 12 includes a ring-shaped body 13 constituting the lower trunk part, and the upper plate 14 and a lower plate 15 that grip the ring-shaped body 13 from above and below. The upper plate 14 and the lower plate 15 constitute a support body for the ring-shaped body 13, and support the ring-shaped body 13 to be rotatable around the shaft 20. Also, the upper plate 14 and the lower plate 15 support the ring-shaped body 13 to be rotatable, and normally rotate integrally with the upper trunk part 11. As shown in FIG. 6, a shaft hole (including an insertion hole 14a of the upper plate 14 and the insertion hole 15b of the lower plate 15) in which the shaft 20 is inserted is formed at the rotational center of the top toy 100 in the lower trunk part assembly 12.

In the example in the drawing, the ring-shaped body 13 is hexagonal in the plan view. The shape of the ring-shaped body 13 is not limited to this, and it is sufficient that it be a shape that can receive an external impact during a top battle, and preferable to have undulations provided on the outer periphery.

Standing walls 13a that extend in an arc shape along the circumferential direction are provided at two locations facing opposite sandwiching the center line on the top surface of the ring-shaped body 13, and joining pieces 13bL, 13bR that overhang inward in an eave shape are formed on each standing wall 13a.

A partition 13c is formed standing upright between the joining pieces 13bL, 13bR. These joining pieces 13bL, 13bR selectively engage with the joining pieces 11e of the upper trunk part 11. Specifically, the joining piece 13bL is the joining piece used when the top toy 100 is rotated counterclockwise, and the joining piece 13bR is the joining piece used when rotating the top toy 100 clockwise. The lower trunk part assembly 12 of this embodiment is used for both rotations (for clockwise rotation and for counterclockwise rotation). Specifically, by exchanging the upper trunk part 11, it is possible to change the top toy 100 to be for clockwise rotation or for counterclockwise rotation.

Crescent-shaped recesses (first engagement part) 13d, 13e in which a projecting part (second engagement part) 16b that is crescent-shaped in the plan view of a movable member 16 described later is fitted are provided adjacent on the inner periphery of the ring-shaped body 13. A projecting part 13f is formed between the recesses 13d, 13e (see FIG. 17 and FIG. 18). Here, the recess 13d is fitted on the projecting part 16b described later in a state with the top toy 100 for clockwise rotation assembled, and the recess 13e is fitted on the projecting part 16b described later in a state with the top toy 100 for counterclockwise rotation assembled.

FIG. 7 is a perspective view of the upper plate 14.

The upper plate 14 has a core body 14b that is circular in the plan view on which is formed the insertion hole 14a through which the shaft 20 is inserted, and overhang parts 14c, 14c that are fan-shaped in the plan view and overhang from the core body 14b in a direction away from each other.

On the lower side of the core body 14b, elastic pieces 14e protruding facing downward with inward facing claws 14d formed on the tip are provided respectively at two locations facing opposite sandwiching the center line. The two elastic pieces 14e, 14e constrict and swell by elasticity in the radial direction of the core body 14b. The claws 14d project into the shaft hole (insertion hole 14a, insertion hole 15b), and are selectively locked to one of a gear 24a (first engagement part) or a gear 24b (second engagement part) described later by a prescribed energizing force. In the embodiment, the “prescribed energizing force” is the energizing force given by the elasticity of the elastic pieces 14e.

Meanwhile, a counterbore hole 14f is formed on the overhang part 14c. Each overhang part 14c is arranged between the two standing walls 13a, 13a of the ring-shaped body 13. Each overhang part 14c can move between the two standing walls 13a, 13a centered around the shaft 20.

A guide wall 15a that fits inside of the ring-shaped body 13 and guides the rotation of the ring-shaped body 13 in sliding contact is erected on the top surface of the lower plate 15. The insertion hole 15b of the shaft 20 is formed inside the guide wall 15a. The insertion hole 15b constitutes the shaft hole formed on the trunk part 10. Two elastic pieces 14e, 14e of the upper plate 14 are inserted respectively so that the claws 14d face the shaft center inside the insertion hole 15b. As a result, the claws 14d are in a projecting state inside the insertion hole 15b which is the shaft hole (see FIG. 6). Two claws 14d are arranged facing opposite sandwiching the center line inside the insertion hole 15b which is the shaft hole. Also, female threaded bosses 15c, 15d are erected on the top surface of the lower plate 15 at two locations facing opposite sandwiching the center line.

A recess and projection part is formed on the outside surface of the bottom edge part of the trunk part 10. In the embodiment, as shown in FIG. 6, FIG. 9, and FIG. 11, a recess and projection part 151 in which projecting parts 151a and recesses 151b are repeated is formed so as to surround the outer periphery of the insertion hole 15b on the lower surface of the lower plate 15. As described later, the recess and projection part is also formed on the shaft 20 of the embodiment, and the recess and projection part 151 on the trunk part 10 side corresponds to the recess and projection part on the shaft 20 side. With the recess and projection part 151 of the embodiment, the projecting part 151a and the recess 151b are provided in pairs at point symmetrical positions sandwiching the shaft center, and these are alternately repeated.

FIG. 8 is a plan view of the top toy 100 in a state with the upper trunk part 11 and the upper plate 14 removed.

One boss 15c is a rectangular projection in the plan view, and the hollow movable member 16 that has a rectangular frame shape in the plan view is externally fitted on this boss 15c. Though not particularly limited, the movable member 16 is constituted from POM (PolyOxyMethylene), for example. The length dimension in the radial direction of the hollow part is greater than the length dimension in the radial direction of the boss 15c, and the movable member 16 can move within a prescribed range in the radial direction. An arc-shaped part 16a is formed inside the movable member 16, and can abut the outer periphery of the shaft 20. Meanwhile, the projecting part 16b that is crescent shaped in the plan view is formed on the outside of the movable member 16. The projecting part 16b is fitted in one of the recesses 13d, 13e of the inner periphery of the ring-shaped body 13 according to the rotation position with respect to the lower plate 15 of the ring-shaped body 13. The depth dimension of the recesses 13d, 13e is set to a level such that the projecting part 16b does not come out from the recesses 13d, 13e even when the movable member 16 moves radially inward. However, when an external force of a prescribed size acts between the ring-shaped body 13 and the support body, the ring-shaped body 13 undergoes elastic deformation by mutual sliding contact, the projecting part 16b comes out from the recesses 13d, 13e (goes over the projecting part 13f), and the ring-shaped body 13 and the support body rotate relative to each other.

In a state with the ring-shaped body 13 sandwiched by the upper plate 14 and the lower plate 15, male screws 14g that go through the counterbore holes 14f of the upper plate 14 are screwed into female threaded bosses 15c, 15d.

Shaft 20

FIG. 9 and FIG. 11 are perspective views showing the shaft 20 and its periphery. In the drawing, the ring-shaped body 13 is omitted. FIG. 10 is a perspective view showing the state with the lower plate 15 further omitted from the state shown in FIG. 9. FIG. 12 is a perspective view showing the state with the lower plate 15 further omitted from the state shown in FIG. 11.

The shaft 20 is configured to be rod-shaped. The shaft head 21 of the shaft 20 (see FIG. 3) has a complementary shape to the fitting hole 11b of the upper trunk part 11. As described previously, in this embodiment, recesses and projections are formed at approximately equal intervals along the circumferential direction on the inner periphery surface of the fitting hole 11b, and on the shaft head 21 of the shaft 20, a pair of projection parts 21a that fit in the recesses and projections is provided at point symmetrical positions sandwiching the shaft center. This shaft head 21 fits in the fitting hole 11b of the upper trunk part 11, and as a result, the shaft 20 is able to rotate integrally with the fitting hole 11b forming part (fitted part). When the fitting hole 11b of the upper trunk part 11 is a polygon shape, the shaft head 21 of the shaft 20 is also formed in a polygon shape that fits in this.

Also, below the shaft head 21 is an abutted part 22 with which the arc-shaped part 16a of the movable member 16 can abut. As a result of the arc-shaped part 16a abutting the abutted part 22, rotational resistance is formed between the ring-shaped body 13 and the shaft 20.

Furthermore, a constricted part 23 is formed below the abutted part 22, and the claws 14d of the upper plate 14 are engaged with this constricted part 23. As a result, the shaft 20 is picked up and held by the claws 14d. In the embodiment, gears 24a, 24b are formed on the outer periphery of the constricted part 23, and the claws 14d are selectively locked and meshed with one of the gears 24a, 24b. The gear 24a is the first engagement part, and the gear 24b is the second engagement part in which the height direction position (height position in the axial direction) is lower than that of the gear 24a which is the first engagement part.

The gear 24a which is the first engagement part is provided at least in a pair at point symmetrical positions sandwiching the shaft center. In the embodiment, a plurality of the first engagement parts and the second engagement parts are formed continuously in the circumferential direction, and are in gear form. The gear 24b which is the second engagement part is provided at least in a pair at point symmetrical positions sandwiching the shaft center. The position at which the gear 24a is provided and the position at which the gear 24b is provided are displaced at a prescribed angle in the circumferential direction. In the embodiment, the prescribed angle is 90 degrees. FIG. 9 and FIG. 10 show the state with the claws 14d meshed with the gear 24a which is the first engagement part, and FIG. 11 and FIG. 12 show the state with the claws 14d meshed with the gear 24b which is the second engagement part. In the top toy 100 of the embodiment, by the claws 14d being locked to either of the gear 24a or 24b, the trunk part 10 and the shaft 20 are engaged, and as described later, it is possible to change the height of the top toy 100.

At least a portion of the gear 24a which is the first engagement part and the gear 24b which is the second engagement part is connected across the circumferential direction of the shaft 20. In the example shown in FIG. 3, etc., the bottom side of the gear 24a which is the first engagement part and the top side of the gear 24b which is the second engagement part are connected in the circumferential direction of the shaft 20. For this reason, as described later, when the top toy 100 receives an impact, it is possible to change the engagement position from the engagement part (gear) the claws 14d are initially meshed with to a different engagement part (gear).

A flange part 25 that overhangs radially outward along the entire circumference is formed below the constricted part 23 which is the outer periphery of the shaft 20 (below the position at which the gear 24a which is the first engagement part and the gear 24b which is the second engagement part are provided). The flange part 25 is a flange part that overhangs facing the outside of the shaft 20.

A recess and projection part is formed in the circumferential direction on the top surface of this flange part 25. In the embodiment, a pair of projecting parts 26 projecting in the height direction of the top toy 100 are provided at point symmetrical positions sandwiching the rotational center of the top toy 100 on the shaft 20. When the shaft 20 is inserted from below in the insertion holes 15b, 14a of the lower trunk part assembly 12, the projecting part 26 contacts the lower surface of the lower plate 15. As described previously, the recess and projection part 151 is also formed on the trunk part 10 side. In the embodiment, a pair of the projecting part 151a and the recess 151b are provided alternately at point symmetrical positions sandwiching the shaft center on the lower surface side of the lower plate 15. When the projecting part 26 on the shaft 20 side is in a state coming into contact with the projecting part 151a of the trunk part 10 side, the claws 14d are locked with the gear 24a which is the first engagement part. When the projecting part 26 on the shaft 20 side is in a state received in the recess 151b on the trunk part 10 side, specifically, when the recesses and projections of the shaft 20 side and the recesses and projections of the trunk part 10 side are in a state fitted together, the claws 14d are locked with the gear 24b which is the second engagement part. In this embodiment, the recesses and projections on the shaft 20 side are formed in a wave shape along the circumferential direction. Specifically, the top end side of the projecting part 26 facing the recess and projection part 151 on the trunk part 10 side is a smooth curve shape with no angles. A tapered part that becomes narrower facing upward is provided on this flange part 25, and as a result, when the shaft 20 is inserted in the insertion hole 15b of the lower plate 15, the shaft 20 may be securely held in the center.

It is also preferable to have a gear that can mesh with an external rack provided below the flange part 25 which is the flange part which is the outer periphery of the shaft 20. With this embodiment, as shown in FIG. 3, etc., below the flange part 25, a gear 27 that meshes with teeth 93a of a battle stadium 90 described later is formed. Gears 24a, 24b are formed inside the constricted part 23 on the shaft 20 of the embodiment, and one of the gears 24a, 24b meshes with the claws 14d. For this reason, it is easier for the shaft 20 to rotate integrally with the upper trunk part 11. As a result, when the gear 27 meshes with the teeth 93a of a guide section 93, it is easier for the rotational force of the upper trunk part 11 to be transmitted to the guide section 93, and since the teeth 93a receive a strong kick, the movement accelerates easily.

It is also possible to prepare a plurality of types of shafts 20 having different shaft diameters and shapes at a prescribed portion to be exchangeable.

For example, when the shaft diameter of the abutted part 22 is a large diameter, in a state with the arc-shaped part 16a on the inside of the movable member 16 abutting the abutted part 22 of the shaft 20, as shown in FIG. 17, the projecting part 16b and the recess 13d are fitted deeply, and the rotational resistance becomes greater. Therefore, for the ring-shaped body 13, it is difficult for the ring-shaped body 13 to rotate with respect to the upper trunk part 11 or the support body. As a result, the top toy 100 is not disassembled easily. When the shaft diameter of the abutted part 22 is made to be a medium diameter, in a state with the arc-shaped part 16a inside the movable member 16 abutting the abutted part 22 of the shaft 20, as shown in FIG. 18, the projecting part 16b and the recess 13d are fitted at a medium level. Therefore, compared to when the shaft diameter of the abutted part 22 is a large diameter, the ring-shaped body 13 is in a state with low rotational resistance with respect to the upper trunk part 11 or the support body, and rotation becomes a little bit easier. Furthermore, when the shaft diameter of the abutted part 22 is made to be a small diameter, in a state with the arc-shaped part 16a inside the movable member 16 abutting the abutted part 22 of the shaft 20, the projecting part 16b and the recess 13d are more shallowly fitted than when the shaft diameter of the abutted part 22 is a medium diameter. Therefore, the ring-shaped body 13 rotates at an even easier level with respect to the upper trunk part 11 or the support body. As a result, the top toy 100 is disassembled relatively easily.

Also, for example when the tip of the shaft 20 is flat, it is easy for the top toy 100 to move around a lot. When the diameter of the tip of the shaft 20 is slightly small, and a taper is formed to be semi-flat, though not as much as when the tip of the shaft 20 is flat, it is easy for the top toy 100 to move around. When the tip of the shaft 20 is made to be a small projection, compared to an item without a small projection, the top toy 100 spins longer. When the surface on which the small projection of the shaft 20 is formed is flat, it is possible to give the characteristic of the top toy 100 not tipping over easily even if it tilts. It is also possible to make the tip of the shaft 20 be hemispherical. In this case, though not as much as when the tip of the shaft 20 is flat, it is possible to have the top toy 100 move around relatively well.

Assembly Method

FIG. 13 and FIG. 14 are plan views of the top toy 100 in a state with the upper trunk part 11 removed.

First, since the upper trunk part 11 is for clockwise rotation, the upper plate 14 and the ring-shaped body 13 are rotated relative to each other to align the triangle mark RM on the “R” character side on the upper plate 14 with the triangle mark M on the ring-shaped body 13 (FIG. 13). At this time, the projecting part 16b of the movable member 16 is fitted into the recess 13e (see FIG. 8) of the inner periphery of the ring-shaped body 13.

In this state, the upper plate 14 is aligned with the fitting wall 11d of the upper trunk part 11, and the upper trunk part 11 and the lower trunk part assembly 12 are butted against each other. As a result, a portion of the upper plate 14 is fitted into the fitting wall 11d.

In this state, the ring-shaped body 13 is rotated relatively clockwise with respect to the upper trunk part 11. At this time, the upper plate 14 rotates relatively counterclockwise together with the upper trunk part 11 with respect to the ring-shaped body 13, and the triangle mark LM on the upper plate 14 is aligned with the triangle mark M on the ring-shaped body 13 (FIG. 14). As a result, the bottom surface of the joining piece 13bR of the ring-shaped body 13 abuts the top surface of the joining pieces 11e of the upper trunk part 11, joining the lower trunk part assembly 12 and the upper trunk part 11. Also, the projecting part 16b of the movable member 16 goes over the projecting part 13f and is fitted in the recess 13d (see FIG. 8).

After that, the shaft 20 is inserted from below in the trunk part 10 and the shaft head 21 is fitted in the fitting hole 11b. As a result, the shaft 20 is picked up and held by the claws 14b, and the claws 14d mesh with either the gear 24a or 24b. However, by pulling the shaft 20 downward, it is possible to easily remove it from the lower trunk part assembly 12.

By doing the above, the top toy 100 is assembled.

When the top toy 100 is for rotating counterclockwise, first, the triangle mark LM of the “L” character side on the upper plate 14 is aligned with the triangle mark M on the ring-shaped body 13, and the lower trunk part assembly 12 is joined with the upper trunk part 11. The relative rotation direction during assembly in this case is the opposite to the case described above.

Top Toy 100 Disassembly

In a top battle, when the other top toy contacts the ring-shaped body 13 and an external force acts on the ring-shaped body 13 in the direction opposite to the rotation direction of the top toy 100, while the rotation of the ring-shaped body 13 stops, the upper trunk part 11 and the support body continue rotating due to inertial force. As a result, the ring-shaped body 13 rotates relatively counterclockwise in relation to the support body, and by sliding contact, the projecting part 16b separates from the recess 13d of the inner periphery of the ring-shaped body 13 (goes over the projecting part 13f) and fits into the recess 13e.

In this position, the joining piece 13bR of the ring-shaped body 13 separates from the joining pieces 11e of the upper trunk part 11, disassembling into two pieces, the upper trunk part 11, and the lower trunk part assembly 12 and the shaft 20.

When the top toy 100 is for counterclockwise rotation, the relative rotation direction during disassembly is opposite to the case described above.

Top Shooting Device 80

FIG. 15 is a perspective view showing a top shooting device 80.

The top shooting device 80 includes a top holder 81 that holds the rotationally energized top toy 100. The top holder 81 is provided with the same number of insertion pieces 81a corresponding to the arc-shaped grooves 11a of the top toy 100. A locking 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 11a of the top toy 100, the top toy 100 is rotated relatively in the direction opposite to the rotationally energized direction of the top toy 100 with respect to the top holder 81, and by the locking part 81b getting under the edge wall of one end part of the arc-shaped groove 11a, the top toy 100 is attached to the top holder 81.

A handle 82 is provided on the top shooting device 80. 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, which is rotated by the rotation of the input rotor.

With this top shooting device 80, the top toy 100 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 100 continues rotating due to inertial force, so the locking part 81b comes out from under the edge wall of one end part of the arc-shaped groove 11a, and is pushed out by sliding contact with the inclined surface of the back of the insertion piece 81a, and the top toy 100 is shot.

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.

Battle Stadium 90

FIG. 16 is a perspective view showing the external appearance of the battle stadium 90.

The bottom surface of a field 91 of the battle stadium 90 is a concave curved surface, and the field 91 is covered by a transparent cover 92 with an open center. The guide section 93 on which are formed teeth 93a that mesh with the gear 27 of the shaft 20 of the top toy 100 that moves around inside the field 91 is arranged in the field 91.

With this battle stadium 90, by meshing the teeth 93a with the gear 27 of the shaft 20 of the top toy 100, the top toy 100 is rolled with respect to the guide section 93, and it is possible to increase the speed at which the top toy 100 moves around.

Operation

Next the operation of the top toy 100 according to the present embodiment is explained.

When playing with the top toy 100, after assembling the trunk part 10, the shaft 20 is inserted in the shaft hole (insertion hole 15b of the lower plate 15) of the trunk part 10. At this time, the user meshes the claws 14d provided on two elastic pieces 14e, 14e of the upper plate 14 with one of the gears 24a, 24b of the shaft 20. For example, when the user meshes the claws 14d with the gear 24a, the projecting part 26 on the shaft 20 side is in a state in contact with the projecting part 151a of the trunk part 10 side (see FIG. 9 and FIG. 10). In this state, the height of the top toy 100 is in a high state. In contrast to this, when the user meshes the claws 14d with the gear 24b, the projecting part 26 on the shaft 20 side is accepted in the recess 151b on the trunk part 10 side, resulting in a state with the recesses and projections on the shaft 20 side being fitted with the recesses and projections on the trunk part 10 side (see FIG. 11 and FIG. 12). In this state, the height of the top toy 100 is in a low state. When the height of the top toy 100 changes, the rotational characteristics of the top toy 100 change, but with the embodiment, not only do the claws 14d mesh with the gears 24a, 24b, but also the recesses and projections on the shaft 20 side are matched with the recesses and projections on the trunk part 10 side, so it is easier for the initial settings by the user to be kept. As described previously, the top end side of the projecting part 26 of the shaft 20 facing the recess and projection part 151 on the trunk part 10 side is a smooth curve shape with no angles. For that reason, even in a case when the claws 14d are set in an incomplete position due to the setting method of the user, etc., the recess and projection part 151 on the trunk part 10 side slips and moves along the curve of the projecting part 26 to be fine-tuned. As a result, the claws 14d are pulled to a position at which they mesh with one of the gear 24a or the gear 24b and are stabilized.

When there is a desire to change the rotation characteristics of the top toy 100, the user switches the gear 24a, 24b to which the claws 14d are meshed. With this embodiment, by performing a top battle, etc., when an impact is applied to the top toy 100, the recess and projection part 151 on the trunk part 10 side slips and moves along the curve of the projecting part 26. As a result, the claws 14d slip and move from the gear 24a, 24b they initially meshed with to a different gear 24a, 24b, switching from the state initially set by the user to a different state. Specifically, the claws 14d are locked to the gear 24a (first engagement part) or the gear 24b (second engagement part) by the energizing force imparted by the elasticity of the elastic pieces 14e. For that reason, when the top toy 100 receives an impact and the elastic pieces 14e, 14e swell in the radial direction, it is possible for the mesh state of the claws 14d with the gears 24a, 24b to change. For example, when the claws 14d were initially meshed with the gear 24a and transitioned to a state of being meshed with the gear 24b by receiving an impact, the height of the top toy 100 becomes lower. When the claws 14d were initially meshed with the gear 24b and transition to a state meshed with the gear 24a by receiving an impact, the height of the top toy 100 becomes higher. In this way, the top toy 100 of the embodiment can have a change in rotation characteristics of the top toy 100 by incidentally switching to either the direction of the height becoming higher or the direction of becoming lower.

Effect

As described above, the top toy 100 of the present embodiment is a top toy 100 including the trunk part 10 and the shaft 20, where a shaft hole (insertion hole 15b of the lower plate 15) is formed in the rotational center of the top toy 100 in the trunk part 10, and in the assembled state, the shaft 20 is inserted in the insertion hole 15b. The shaft 20 has at the outer periphery the gear 24a which is the first engagement part and the gear 24b which is the second engagement part for which the height direction position is lower than that of the gear 24a, inside the shaft hole (insertion hole 15b of the lower plate 15), the claws 14d that project inside are provided, and by the claws 14d being locked to either of the gear 24a or the gear 24b of the shaft 20, the trunk part 10 and the shaft 20 are engaged, making it possible for the height of the top toy 100 to change.

As a result, in addition to the user easily changing the height of the top toy 100, when an impact is received by a top battle, etc., the mesh state of the claws 14d with the gears 24a, 24b switches, and it is possible to change the height of the top toy 100 to either the direction of becoming higher or the direction of becoming lower. For that reason, the center of gravity position or the rotation characteristics of the top toy 100 change, and it is possible to enjoy a variety of movements and battles.

In the embodiment, the trunk part 10 includes the upper trunk part 11 and the lower trunk part (lower trunk part assembly 12) in which the insertion hole 15b which is the shaft hole is formed, and the configuration is such that the upper trunk part 11 (lower trunk part assembly 12) and the shaft 20 can be disassembled by a top battle in which top toys 100 are collided with each other to fight. As a result, it is possible to enjoy the performance by a top battle.

In the embodiment, the claws 14d are provided at two locations facing opposite sandwiching the center line inside the shaft hole (insertion hole 15b of the lower plate 15), at least a pair of the gears 24a which are the first engagement part are provided at point symmetrical positions sandwiching the shaft center, and at least a pair of the gears 24b which are the second engagement part are provided at point symmetrical positions sandwiching the shaft center, and the position at which the first engagement part is provided and the position at which the second engagement part is provided are displaced at a prescribed angle in the circumferential direction.

As a result, both of the pair of claws engage with one of the two of the first engagement part and the second engagement part, so there is no incomplete state such as one of the pair of claws engaging with the first engagement part, and the other engaging with the second engagement part. For that reason, even when the shaft rotates due to receiving an impact from outside, etc., the height of the top toy can be stably in either a high state or a low state.

In the embodiment, the flange part 25 which is a flange part that overhangs facing radially outward is provided below the position at which the gears 24a, 24b mesh which is the outer periphery of the shaft 20, recesses and projections (projecting part 26) are formed in the circumferential direction on the top surface of the flange part 25, the recess and projection part 151 corresponding to the recesses and projections on the shaft 20 side is formed on the outside surface of the bottom edge part of the trunk part 10, and in a state when the projecting part 26 on the shaft 20 side is in contact with the projecting part 151a on the trunk part 10 side, the claws 14d are locked to the gear 24a, and when the recesses and projections (projecting part 26) on the shaft 20 side and the recess and projection part 151 on the trunk part 10 side are in a fitted state, the claws 14d are locked to the gear 24b.

In this way, not only by meshing of the claws 14d and the gears 24a, 24b, but by also changing the fitting status of the recess and projection part 151 of the trunk part 10 side and the projecting part 26 of the shaft 20 side, it is easier to keep the mesh state between the claws 14d and the gears 24a, 24b set by the user, etc.

In the embodiment, the recesses and projections (projecting part 26) on the shaft 20 side and the recess and projection part 151 on the trunk part 10 side are respectively point symmetrical sandwiching the rotational center of the top toy 100. By providing at least a pair of the projecting part 26 on the shaft 20 side and the recess and projection part 151 on the trunk part 10 side at point symmetrical positions, it is possible to stabilize the setting status of the trunk part 10 and the shaft 20 more than when providing at only one location or providing unevenly.

In the embodiment, at least the recesses and projections on the shaft 20 side are formed in a wave shape along the circumferential direction. As a result, smooth sliding movement is easy when the top toy 100 receives an impact, the fitting state between the projecting part 26 on the shaft 20 side and the recess and projection part 151 on the trunk part 10 side can be changed easily, and thus, it is possible to smoothly and reliably switch the meshing state between the claws 14d and the gears 24a, 24b. For that reason, it is easier to incidentally change the height of the top toy 100 to either of the higher direction or the lower direction, and possible to enjoy movement with a high amount of variation.

As in the embodiment, when the gear 24a which is the first engagement part and the gear 24b which is the second engagement part are connected in the circumferential direction of the shaft 20 at one portion, it is possible to easily change the engagement position from the engagement part (gear) the claws 14d were initially meshed with to a different engagement part (gear).

In the embodiment, because the first engagement part and the second engagement part are formed in a gear shape, by the claws 14d meshing with the first engagement part or the second engagement part, it is easy for the shaft 20 to rotate integrally with the trunk part (upper trunk part).

In the embodiment, teeth (rack) 93a are formed on the inner periphery surface of the battle stadium 90 which is the battle site for the top toys 100, and for that reason, by the gear 27 formed on the outer periphery of the shaft 20 meshing with those teeth (rack) 93a, and it is possible to cause changes in the movement such as acceleration of the top toy 100.

Other

Above, an embodiment of the present disclosure was explained, but it goes without saying that the present disclosure is not limited to this embodiment and that various modifications are possible within a scope that does not stray from the gist.

For example, in this embodiment, in the top toy 100, an example was shown when the claws 14d mesh with either of gears 24a, 24b to change the height direction in two levels, but it is also possible to provide three or more types of gears (engagement parts) with respectively different height direction positions, for example, to change the height direction in three or more levels.

In the embodiment, an example was shown including recesses and projections (projecting part 26) on the shaft 20 side and the recess and projection part 151 on the trunk part 10 side, but it is not absolutely necessary to include the recesses and projections (projecting part 26) on the shaft 20 side and the recess and projection part 151 on the trunk part 10 side.

Also, the shape, provided number, and provision position, etc., of the recesses and projections (projecting part 26) on the shaft 20 side and the recess and projection part 151 on the trunk part 10 side are not limited to those shown in the embodiment.

In the embodiment, it is preferable to have a shape that makes sliding movement easy for the recesses and projections (projecting part 26) on the shaft 20 side and the recess and projection part 151 on the trunk part 10 side, and an example was shown when the recesses and projections on the shaft 20 side are formed in a wave shape along the circumferential direction, but the shape of the recesses and projections (projecting part 26) on the shaft 20 side and the recess and projection part 151 on the trunk part 10 side are not limited to this. For example, it is also possible to form the recess and projection part 151 on the trunk part 10 side in a wave shape along the circumferential direction. It is also possible to form both the recesses and projections (projecting part 26) on the shaft 20 side and the recess and projection part 151 on the trunk part 10 side in a wave shape in the circumferential direction. In this case, it is easier for the recesses and projections (projecting part 26) on the shaft 20 side and the recess and projection part 151 on the trunk part 10 side to slide and move, and easier to change the height of the top toy 100.

In the embodiment, an example was shown in which the top toy 100 is disassembled and the height is changed by impact during a top battle, but the top toy 100 disassembly and the height change are not limited to being by impact during a top battle. For example, it is also possible to have the top toy 100 disassemble or have the height change due to impact by contacting a wall, etc., during use when not in a battle with another top toy, for example.

In the embodiment, an example was shown in which with the first engagement part and the second engagement part are recesses sunken radially inward of the shaft 20, and the claws 14d that project inside the shaft hole (insertion hole 15b) lock with the recess, by which the shaft 20 is engaged with the trunk part 10, but the first engagement part and the second engagement part are sufficient provided that they are locked inside the shaft hole (insertion hole 15b) of the trunk part 10, and are not limited to being a recess. For example, the first engagement part and the second engagement part may also be configured to be projecting parts projecting in the radial direction of the shaft 20, to lock with the recess on the trunk part 10 side.

Above, a number of embodiments of the present disclosure were explained, but the scope of the present disclosure is not limited to the embodiments described above. The configuration, etc., of the top toy 100 shown in the embodiments above can be changed as appropriate in a scope that does not stray from the gist of the present disclosure. The present disclosure includes the scope noted in the claims and the equivalent scope thereof. The embodiments of the invention shown above and their modifications can be used in combination as appropriate in a scope that does not mutually conflict.

According to a first aspect of the disclosure, using the rotation of a shaft, it is possible to switch the locking state of claws supporting the shaft and a first engagement part and a second engagement part, and it is possible to change the height of a top toy to either a direction that goes higher or a direction that goes lower with a simple structure.

As a result, it is possible to change the top toy center of gravity position or rotation characteristics, and enjoy a variety of movements and battles.

According to a second aspect of the disclosure, it is possible to enjoy a variety of movements and performances of a top toy.

With a third aspect of the disclosure, the claws face opposite sandwiching the shaft center, and the first engagement part and the second engagement part are respectively in a pair at point symmetrical positions sandwiching the shaft center. For that reason, there is no occurrence of an incomplete state such as by twisting, with one out of the pair of claws engaging with the first engagement part, and the other engaging with the second engagement part.

In this way, it is possible for both of the pair of claws to reliably engage with one or the other of the first engagement part and the second engagement part, and even when the shaft is rotated by receiving an impact from outside, etc., the height of the top toy can be stably kept in a higher state or a lower state.

With a fourth aspect of the disclosure, it is easy to maintain the locking state of the claws with the first engagement part and the second engagement part set by a user, etc.

With a fifth aspect of the disclosure, it is possible to stabilize the set state of the trunk part and the shaft.

With a sixth aspect of the disclosure, when the top toy receives an impact, it slides smoothly and moves easily, and it is easy to change the fitting state between the recesses and projections of the shaft side and the recesses and projections of the trunk part side. As a result, there is smooth switching of the locking state of the claws with the first engagement part and the second engagement part when the top toy receives an impact, and it is possible to incidentally change the height of the top toy in the higher direction or the lower direction. For that reason, it is possible to change the center of gravity position and the rotation characteristics of the top toy, and to enjoy varied movement and battles.

With a seventh aspect of the disclosure, when the top toy receives an impact, etc., it is possible to easily change the engagement position of the claws from the engagement part they initially meshed with to a different engagement part.

With an eighth aspect of the disclosure, because the first engagement part and the second engagement part are formed in a gear form, by the claws meshing with the first engagement part or the second engagement part, it is easy for the shaft to rotate integrally with the trunk part (upper trunk part).

When teeth (rack) are formed on an external structure such as the inner peripheral surface of a battle stadium which serves as a site for top toy battles, for example, with a ninth aspect of the disclosure, the gears formed on the outer periphery of the shaft mesh with the teeth (rack), and it is possible to cause changes in the movement such as acceleration of the top toy, etc.
