Patent Description:
In the past, a dedicated top toy game table was used for battling top toys with each other (<CIT>).

With this top toy game table, a protruding wall that partitions the battlefield is provided around the battlefield. When a top toy released into the battlefield moves around and contacts the wall, it moves along the protruding wall, or is struck by the protruding wall and returns to the center of the battlefield again, expanding the battle. From <CIT> a game board is known, which comprises a circular cylinder-shaped toothed wall surrounding a game surface. Teeth are provided on the entire length of the toothed wall in a continuous manner. The whirligig comprises a toothed wheel that cooperates with the teeth of the toothed wall, when the whirligig is rotated on the game surface. The toothed wheel is mounted at a bottom part of the whirligig in a coaxial manner. <CIT> discloses a dynamic entertainment system, which involves an interchangeable top component and interchangeable non-reciprocal rail arrangements enhancing velocity in transit while enabling speedy non-rail transfers between different components.

The speed at which the top toy noted in <CIT> moves around is at its maximum immediately after the top toy is let loose, and generally after that it only attenuates as the rotational energy decreases, and even if it contacts the protruding wall, the top toy slides along the protruding wall in accordance with rotation of the top toy, and though a certain amount of change is seen in the speed at which it moves around, it only moved around within a predictable range.

In consideration of such circumstances, the present invention provides a top toy set in which it is possible to change how they move around.

This problem is solved by a top toy set with the features of independent claims <NUM> and <NUM>. Preferred embodiments of the inventive top toy set are disclosed in the dependent claims.

When the second teeth are engaged with the first teeth, the top toy rolls along the guide member without sliding, so can be moved effectively. When the second gear is fixed to the body, by engagement of the second teeth and the first teeth, the rotation of the top toy is transmitted to the guide member, and it is possible to rapidly accelerate the movement of the top toy. In this way, it is possible change the movement by the amount of engagement of the second teeth and the first teeth.

When the second teeth are abutted on the guide member, playing is difficult, and engaging of the second teeth and the first teeth is easier.

The teeth forming member is a gear for which the first teeth are provided on the rotation shaft, so the configuration of the teeth forming member is simple, and the attachment structure is also simple. Because it is a gear, it is also easy to use the dynamic force of the top toy.

Because the resistance means are provided, the rotation of the top toy is transmitted to the first teeth of the guide member via the teeth forming member, so it is possible to increase the speed at which the top toy moves around.

When the gear collides with the guide member, the gear rotates in the direction that mitigates impact on the rotation shaft, so it is easier for the first teeth to engage with the second teeth. After engagement of the first teeth and the second teeth, by the first teeth rotating in accordance with the rotation of the rotation shaft, the speed at which the top toy moves around increases.

By operation of the clutch, the first teeth and the second teeth engage easily, and it is possible to increase the speed at which the top toy moves around.

When the gear collides with the guide member, the gear is rotated in resistance to the energizing force of the plate spring in the direction that mitigates the impact on the rotation shaft, so the impact is effectively absorbed, and it is easier for the first teeth to engage with the second teeth. After the first teeth engage with the second teeth, by the gear rotating in accordance with the rotation of the rotation shaft, the speed at which the top toy moves around increases.

When the gear collides with the guide member, the gear is rotated in resistance to the energizing force of the coil spring in the direction that mitigates impact on the rotation shaft, so it is possible to obtain the same effect as that of the embodiment in which the resistance means is configured from an engagement clutch.

When the gear collides with the guide member, the friction clutch rotates the gear in the direction that mitigates the impact on the rotation shaft, so it is possible to obtain the same effect as with the embodiment, in which the resistance means is configured from an engagement clutch.

When the gear collides with the guide member, the elastic member is elastically deformed and the gear is rotated in the direction that mitigates impact on the rotation shaft, so it is possible to obtain the same effect as with the embodiment, in which the resistance means is configured from an engagement clutch.

It is possible to change the characteristics of the top toy by replacing the abutting member.

Specifically, when using the abutting member for which the abutting part is formed at a relatively far distance from the projection, the dynamic resistance between the rotation shaft and the gear is small, and when using the abutting member for which the abutting part is formed at a relatively close distance from the projection, the dynamic resistance between the rotation shaft and the gear is large.

It is possible to realize a top toy set that effectively exhibits the function of the above-mentioned top toys.

When the first frictional resistance part abuts the guide member, the top toy rolls along the guide member, so it is possible to move it effectively. When the first frictional resistance part is fixed to the body, by the abutting of the first frictional resistance part and the guide member, the rotation of the top toy is transmitted to the guide member, and it is possible to accelerate the movement of the top toy. In this way, it is possible to change the movement by the amount that the first frictional resistance part and the guide member abut.

When the first frictional resistance part is abutted on the guide member, playing is difficult, and abutting of the first frictional resistance part and the guide member is easier.

The first frictional resistance part is the roller provided on the rotation shaft, so the configuration is simple, and the attachment structure is also simple. Since this is a roller, it is also easy to use the dynamic force of the top toy.

The first frictional resistance part abuts the second frictional resistance part of the guide member, so the grip force further increases, and the roller rolls more easily.

Because the resistance means is provided, the rotation of the top toy is transmitted to the guide member via the first resistance part, and the speed at which the top toy moves around can be increased.

When the roller collides with the guide member, the roller rotates in the direction that mitigates impact, so the roller more easily abuts the guide member. After abutting of the roller and the guide member, by the roller rotating in accordance with the rotation of the rotation shaft, the speed at which the top toy moves around increases.

By operation of the clutch, the first frictional resistance part and the second frictional resistance part easily abut, and it is possible to increase the speed at which the top toy moves around.

When the roller collides with the guide member, the roller rotates in resistance to the energizing force of the plate spring in the direction that mitigates impact, so abutting of the roller and the guide member is easier. After abutting of the roller and the guide member, by the roller rotating in accordance with rotation of the rotation shaft, the speed at which the top toy moves around increases.

When the roller collides with the guide member, the roller rotates in resistance to the energizing force of the coil spring, in the direction that mitigates impact, so it is possible to obtain the same effects as with the twentieth means.

When the roller collides with the guide member, the friction clutch rotates the roller in the direction that mitigates impact, so it is possible to obtain the same effect as with the embodiment mentioned before.

When the roller collides with the guide member, the elastic member is elastically deformed and rotates the gear in the direction that mitigates impact on the rotation shaft, so it is possible to obtain the same effect as with the embodiment mentioned before.

It is possible to change the characteristics of the top toy by exchanging the abutting member.

Specifically, when using the abutting member for which the abutting part is formed at a relatively far distance from the projection, the dynamic resistance between the rotation shaft and the roller is smaller, and when using the abutting member for which the abutting part is formed at a relatively close distance to the projection, the dynamic resistance between the rotation shaft and the roller is greater.

It is possible to realize a top toy set that effectively exhibits the functions of the above-mentioned top toys.

Following, a top toy set of an embodiment of the present invention is explained.

<FIG> is a perspective view of a top toy set <NUM> of an embodiment.

The top toy set <NUM> of the present embodiment comprises a top toy <NUM>, and a top toy game table <NUM> on which to battle top toys with each other.

<FIG> is an exploded perspective view of a top toy game table <NUM>. <FIG> is a perspective view of a fastener <NUM>.

Overall, the top toy game table <NUM> is approximately square in the plane view and is box-shaped, and comprises: a base board <NUM> that constitutes a battlefield <NUM> of the top toy <NUM>; a cover body <NUM> that can be attached and detached with the base board <NUM>; and a fastener <NUM> (see <FIG>) for fixing the cover body <NUM> to the base board <NUM>.

The base board <NUM> is approximately square in the plane view and has a shape with one corner missing. The base board <NUM> has a prescribed thickness, with the top surface being a bowl-shaped concave surface, and the center part constituting the battlefield <NUM>. Inside the concave surface of the base board <NUM>, two sets of band-shaped guide members <NUM> are provided extending in the horizontal direction to partition the battlefield <NUM>. Each set of guide members <NUM> is formed in a C-shape in the plane view, and teeth are formed on the inner surface at equal intervals in the lengthwise direction. The two sets of guide members <NUM> are arranged so that the C-shaped recessed parts face each other, and both end parts of each set of guide members <NUM> extend facing the center side of the battlefield <NUM>. As a result, it is possible to move the top toy <NUM> along the guide member <NUM> while being accelerated, and to guide it to collide with another top toy that remains in the center.

A step part <NUM> is formed at each of the three corners of the base board <NUM>. A rectangular hole 94a is formed in the step part <NUM>.

The cover body <NUM> is also approximately square in the plane view. The cover body <NUM> has a prescribed thickness, and has a shape that covers the side and top of the outer periphery part of the base board <NUM> in the plane view. A circular window 91a is formed on the top surface of the cover body <NUM>, and in a state mounted on the base board <NUM>, the battlefield <NUM> is directly visible from this window 91a.

A step part <NUM> is formed on the part corresponding to each of the three corners of the base board <NUM> on the cover body <NUM>. A rectangular hole 95a is formed on the step part <NUM>. In a state with the cover body <NUM> mounted on the base board <NUM>, the step part <NUM> and the step part <NUM> are superimposed, and the rectangular hole 95a and the rectangular hole 94a match vertically.

Of the cover body <NUM>, a corner <NUM> on which the step part <NUM> is not formed is in a state jutting out inclined outward and downward from the base board <NUM>. When the top toy <NUM> that was played in a battle and jumped out from the base board <NUM> contacts this corner <NUM>, it is ejected to outside the base board <NUM>.

<FIG> is a perspective view of the fastener <NUM>.

The fastener <NUM> is configured from a female fitting <NUM> and a male fitting <NUM>.

The female fitting <NUM> comprises a cylinder part 98a, and a flange part 98b is formed directly above the bottom edge of the outer periphery of the cylinder part 98a. When the female fitting <NUM> fixes the cover body <NUM> to the base board <NUM>, the flange part 98b is contacted on the edge of the rectangular hole 95a of the step part <NUM> from above.

The male fitting <NUM> has a structure in which a pair of claws 99b are erected in a recess of a rectangular tray-shaped base 99a.

When the male fitting <NUM> fixes the cover body <NUM> to the base board <NUM>, the edge of the base 99a is contacted on the edge of the rectangular hole 94a of the step part <NUM> from below, and the claw 99b is inserted in a hole of the cylinder part 98a of the female fitting <NUM> from below, and is engaged with the top end of the cylinder part 98a. As a result, the cover body <NUM> is fixed to the base board <NUM>.

<FIG> is an exploded perspective view of the top toy <NUM>.

This top toy <NUM>, roughly divided, comprises a trunk part <NUM> and a shaft part <NUM>.

The trunk part <NUM> is configured from an upper trunk part <NUM> and a lower trunk part <NUM>.

The upper trunk part <NUM> is a composite configured in a disk shape. In the upper trunk part <NUM>, in the plane view, between a circular center part <NUM> and a ring-shaped outer periphery part <NUM> is partitioned by an annular groove <NUM>, and two arc-shaped slits <NUM> are partially formed on the bottom of the annular groove <NUM>. The two slits <NUM> are formed at positions with point symmetry to each other with respect to the axial center.

Furthermore, two L-shaped outward facing joining claws <NUM> are formed on the bottom surface of the upper trunk part <NUM>. The two joining claws <NUM> are provided at positions that have point symmetry to each other with respect to the axial center.

The lower trunk part <NUM> is a composite configured in a disk shape. In the lower trunk part <NUM>, in the plane view, between a circular center part <NUM> and a ring-shaped outer periphery part 33is partitioned by an annular groove <NUM>, with two approximately arc-shaped slits <NUM> formed on the bottom of the annular groove <NUM>. The two slits <NUM> are formed at positions that have point symmetry to each other with respect to the axial center. The annular groove <NUM> has a broader width than the annular groove <NUM>.

On the outer edge of one end in the circumferential direction of each slit <NUM>, a joining claw (not illustrated) that engages with the joining claw <NUM> of the upper trunk part <NUM> and joins the upper trunk part <NUM> and the lower trunk part <NUM> is formed, and at the outer edge of the other end in the circumferential direction of each slit <NUM>, a fitting projection 37b is formed that is fitted in a fitting recess <NUM> described later and that joins the lower trunk part <NUM> and the shaft part <NUM>. The two joining claws (not illustrated) are provided at positions having point symmetry to each other with respect to the axial center, and the two fitting projections 37b are provided at positions having point symmetry with each other with respect to the axial center.

<FIG> is an exploded perspective view of the shaft part <NUM> of the top toy <NUM> seen from the top surface side, and <FIG> is an exploded perspective view of the shaft part <NUM> seen from the bottom surface side.

A rotation shaft <NUM> comprises an inverted cone-shaped tapered shaft tip 51a, and a shaft body 51b connected continuously with the shaft tip 51a. The top edge diameter of the shaft tip 51a is greater than the diameter of the shaft body 51b, and the top edge of the shaft tip 51a juts out outward in a ring shape from the shaft body 51b.

Two D-cut parts 51c are formed on the top edge part of the shaft body 51b. The two D-cut parts 51c are provided at positions having point symmetry with each other with respect to the axial center.

This rotation shaft <NUM> is fixed to a shaft fixing member <NUM> by the top edge part of the shaft body 51b that has passed through a hole 52a of a gear <NUM>, a hole 53a of a cover body <NUM>, and a hole 54a of a claw member <NUM> from below being fitted in a fitting hole 55a of the shaft fixing member <NUM>.

The gear <NUM> is engageable with the teeth of the guide member <NUM>, and the ring-shaped jutting part of the top edge of the shaft tip 51a of the rotation shaft <NUM> is supported from below. A plurality of engaging claws 52b are formed at equal intervals in the circumferential direction on the top edge surface of this gear <NUM>.

The cover body <NUM> is formed in a deep round plate shape, and a hole 53a into which the top edge part of the gear <NUM> fits is formed on the bottom. An outward flange 53b is formed on the top edge of the cover body <NUM>. Two fitting protrusions 53c are formed to jut outward on the outward flange 53b. The two fitting protrusions 53c are provided at positions having point symmetry with each other with respect to the axial center. The fitting recess <NUM> is formed on the fitting protrusion 53c. The fitting protrusions 53c are fit into the slits <NUM> so that the fitting recesses <NUM> and the fitting projection 37b are fitted. As a result, the shaft part <NUM> and the lower trunk part <NUM> are joined.

Two bosses with screw holes 53d are formed inside the cover body <NUM>. The two bosses 53d are provided at positions having point symmetry with each other with respect to the axial center.

Four fitting recesses 53e into which a fitting protrusion 54c described later is fitted are formed at equal intervals in the circumferential direction on the inner surface of the cover body <NUM>.

The claw member <NUM> is formed in a disk shape, and a plurality of engaging claws 54b that can engage with the engaging claws 52b of the gear <NUM> are formed in the circumferential direction on the bottom surface. Four fitting protrusions 54c that fit loosely in the fitting recesses 53e are formed to jut out outward on the outer periphery part of the claw member <NUM>. The claw member <NUM> and the engaging claws 52b constitute the engagement clutch. This engagement clutch, in a half-clutch state, rolls the gear <NUM> along the guide member <NUM>.

The shaft fixing member <NUM> is configured in a ceilinged cylinder shape. This shaft fixing member <NUM> is fitted inside the cover body <NUM>, and the claw member <NUM> is housed internally between it and the cover body <NUM>. On a cylindrical part 55c below a top plate 55b of the shaft fixing member <NUM>, formed are four notches 55d into which fit the fitting protrusions 54c of the claw member <NUM>, and the claw member <NUM> can move vertically within a prescribed range.

The outer periphery part of the top plate 55b of the shaft fixing member <NUM> juts out in ring form from the outer periphery of the cylindrical part 55c. Two arc-shaped notches 55e are formed on this jutting part. The two notches 55e are provided at positions having point symmetry with each other with respect to the axial center. Each notch 55e abuts the outer periphery part of the boss 53d.

Furthermore, as shown in <FIG>, three plate springs 55f of a cut and bent shape are provided at equal intervals in the circumferential direction on the top plate 55b of the shaft fixing member <NUM>. The plate springs 55f press the claw member <NUM> downward, and operate to press the engaging claws 54b against the engaging claws 52b.

A disk-shaped top plate <NUM> is provided above the shaft fixing member <NUM>.

The top plate <NUM> forms the top surface of the shaft part <NUM>, and screw insertion holes 57a are formed at the parts corresponding to the bosses 53d.

The shaft part of male screws (not illustrated) passes through the screw insertion holes 57a from above, and by screwing the male screws with the female screws of the bosses 53d, the top plate <NUM> is fixed to the cover body <NUM>.

The upper trunk part <NUM> and the lower trunk part <NUM> are butted from the axial direction, and the joining claws <NUM> of the upper trunk part <NUM> are inserted in the slits <NUM> of the lower trunk part <NUM> from above. The upper trunk part <NUM> is then rotated in the clockwise direction with respect to the lower trunk part <NUM>. As a result, the joining claws <NUM> of the upper trunk part <NUM> are engaged with the joining claws (not illustrated) of the lower trunk part <NUM>, and the upper trunk part <NUM> and the lower trunk part <NUM> are joined.

Next, the lower trunk part <NUM> to which the upper trunk part <NUM> is attached and the shaft part <NUM> are butted from the axial direction, and the fitting recesses <NUM> and the fitting projections 37b are fitted, and the fitting protrusions 53c are fitted into the slits <NUM>. As a result, the shaft part <NUM> and the lower trunk part <NUM> are joined.

Rotational energization of the top toy <NUM> is done using a launcher (not illustrated). The launcher comprises a fork inserted in the slit <NUM> of the upper trunk part <NUM>, and a rotation mechanism that rotationally operates the fork. The fork is inserted in the slit <NUM> of the upper trunk part <NUM>, and by the fork being rotationally operated by the rotation mechanism, the top toy <NUM> is rotationally energized. The rotationally energized top toy <NUM> is released from the launcher.

When the top toy <NUM> is released into the battlefield <NUM>, it moves around in reaction in the direction opposite to the rotation direction of the top toy <NUM>. At this time, the gear <NUM> rotates integrally with the rotation shaft <NUM>. By moving around, the gear <NUM> of the top toy <NUM> contacts the guide member <NUM>. By the impact force at this time, the gear <NUM> rotates relatively in resistance to the energizing force of the plate springs 55f with respect to the rotation shaft <NUM> and the impact is mitigated. By doing this, it is easier for the top toy <NUM> to temporarily stay near the guide member <NUM>, and the probability of the gear <NUM> engaging with the teeth of the guide member <NUM> improves. Then, in the top toy <NUM>, as shown in <FIG>, when the gear <NUM> engages with the teeth of the guide member <NUM>, in a half-clutch state, the gear <NUM> is rotated in accordance with the rotation of the rotation shaft <NUM>, and moves along the guide member <NUM>, and the movement of the top toy <NUM> is accelerated. In other words, the rotation of the top toy <NUM> is easier to transmit to the guide member <NUM>, and it is possible to accelerate the movement of the top toy <NUM>.

<FIG> is a perspective view of another shaft part 50A. <FIG> is an exploded perspective view of the other shaft part 50A seen from the top surface side. <FIG> is an exploded perspective view of the other shaft part 50A seen from the bottom surface side. In the shaft part 50A, parts that correspond to constituent elements of the abovementioned shaft part <NUM> are given the same code numbers, and the explanation thereof will be omitted as appropriate.

The main difference between this shaft part 50A and the abovementioned shaft part <NUM> is that with the shaft part <NUM>, the pressing of the engaging claws 54b on the engaging claws 52b was performed by the plate springs 55f, whereas with the shaft part 50A, the pressing of the engaging claws 54b on the engaging claws 52b is performed by coil springs <NUM>.

To use this kind of configuration, with the shaft part 50A, a pressing plate <NUM> is provided between the claw member <NUM> and the shaft fixing member <NUM>.

The pressing plate <NUM> is configured in a disk shape, and a hole 61a through which the shaft body 51b of the rotation shaft <NUM> is inserted through the center. Guide rods 61b are erected on the top surface of the pressing plate <NUM> at positions having point symmetry with respect to the axial center, and the guide rods 61b are inserted in the guide holes <NUM> of the shaft fixing member <NUM>, and the guide holes 57b of the top plate <NUM>. Also, the coil springs <NUM> are wound on the guide rods 61b, and the pressing plate <NUM> energizes the claw member <NUM> toward the gear <NUM> side. It is possible to adjust the strength of the engagement clutch of the claw member <NUM> and the engaging claw 52b by the guide rods 61b being pressed from above, and providing a part that regulates the upward movement of the claw member <NUM>.

Two notches 61c are formed on the pressing plate <NUM>. The two notches 61c are provided at positions having point symmetry with each other with respect to the axial center. The notches 61c are abutted on the outer periphery part of the bosses 53d.

In addition, this shaft part 50A differs from the shaft part <NUM> with fine points such as the point that fitting protrusions 53c and screw insertion holes <NUM> are provided on the shaft fixing member <NUM>, but overall they have the same structure.

With the top toy having the shaft part 50A configured in this way, the same action and effect as the top toy <NUM> are exhibited.

<FIG> is a perspective view of another top toy 1A. <FIG> is an exploded perspective view of the other top toy 1A seen from the top surface side. <FIG> is an exploded perspective view of the other top toy 1A seen from the bottom surface side.

A rotation shaft <NUM> of this top toy 1A comprises a shaft tip 71a with a large diameter in a cylinder shape, and a shaft body 71b connected continuously with the shaft tip 71a.

Two D-cut parts 71c are formed on the top edge part of the shaft body 71b. The two D-cut parts 71c are provided at positions having point symmetry with each other with respect to the axial center.

The shaft body 71b of the rotation shaft <NUM> passes through a hole 72a of a gear <NUM> and a hole 73a of a cover body <NUM> from below, and the top edge part is fitted in a fitting hole 74i of the bottom surface of a shaft fixing member <NUM>.

Engaging parts 72b made from wave shaped recesses and projections formed along the entire circumference in the circumferential direction are formed on the outer periphery of the top edge of the gear <NUM>.

A cylinder part is erected inside the top surface recess of the gear <NUM>, and a fitting recess 72c is formed by this cylinder part.

The cover body <NUM> is formed in a deep round plate shape. An outward flange 73b is formed on the top edge of the cover body <NUM>.

Two bosses 73c are formed on the inside of the cover body <NUM>. The two bosses 73c are provided at positions having point symmetry to each other with respect to the axial center.

A screw insertion hole 73d is formed on each boss 73c. Round arc-shaped notches 73e are formed on the outside of each boss 73c at the inner edge part of the outward flange 73b.

Furthermore, other notches 73f are formed on parts separated by <NUM> degrees in the circumferential direction from the notches 73e at the inner edge part of the outward flange 73b. The notches 73f are provided over the part under the outward flange 73b. The two notches 73f are provided at positions having point symmetry to each other with respect to the axial center.

The shaft fixing member <NUM> comprises a base 74b having an approximately rectangular shape in the plane view.

Two tongue pieces 74c corresponding to the notches 73e are attached on the outside of the base 74b, and two belt-shaped elastic pieces 74d with both ends connected to the tongue pieces 74c are attached. A screw insertion hole 74e is formed on each tongue piece 74c. An engaging projection 74f is formed at the lengthwise direction center of the inner surface of each elastic piece 74d. The elastic pieces 74d and the engaging parts 72b constitute the mechanical clutch. This mechanical clutch, in a half-clutch state, rolls the gear <NUM> along the guide member <NUM>.

Furthermore, a fitting projection <NUM> that fits into the inside of the abovementioned fitting recess 72c is formed on the bottom surface of the base 74b, and a fitting hole 74i into which fits the top edge part of the shaft body 71b of the rotation shaft <NUM> is formed on this fitting projection <NUM>.

A circular recess <NUM> is also formed on the top surface of the base 74b, and a counterbore hole 74j is formed at the center. The shaft part of a male screw (not illustrated) passes through the counterbore hole 74j from above, and that male screw screws with a female screw (not illustrated) of the shaft body 51b of the rotation shaft <NUM>.

A circular plate <NUM> is fitted in the circular recess <NUM> of the top surface of a base 74b.

A lid body <NUM> provided above the circular plate <NUM> is formed in approximately a disk shape.

Two bosses with screw holes 76a corresponding to the bosses 73c are attached on the lid body <NUM>, and two notches 76b are formed corresponding to the notches 73f. Male screws (not illustrated) that pass through the screw insertion holes 73d of the cover body <NUM> and the screw insertion holes 74e of the shaft fixing member <NUM> from below are screwed into female screws (not illustrated) of the bosses 76a. In a state with this lid body <NUM> attached to the cover body <NUM>, predetermined gaps are formed between the notches 76b and the notches 73f.

A top plate <NUM> is formed in a disk shape, and an approximately hexagonal convex part 77a in the plane view is formed on the top surface center. A hole 77b in which a female screw is formed is formed at the center of the convex part 77a, and a bolt <NUM> screws into the female screw.

Two L-shaped outward facing claws 77c corresponding to the notches 76b are formed on the bottom surface of the top plate <NUM>. The two outward facing claws 77c are provided at positions having point symmetry with each other with respect to the axial center. An abutting projection 77d is formed on the inside of each outward facing claw 77c. This top plate <NUM> has the outward facing claws 77c inserted in gaps between the notches 76b and the notches 73f, and by the outward facing claws 77c being engaged with the edge of the notches 73f, is attached to the cover body <NUM>.

In <FIG>, shown are three top plates 77A, 77B, 77C with mutually different formation positions of the abutting projections 77d with respect to the outward facing claws 77c.

With these three top plates 77A, 77B, 77C, the formation position of the abutting projection 77d differs in the circumferential direction. The abutting projection 77d of the top plate <NUM> abuts the elastic piece 74d of the shaft fixing member <NUM>, and so that the engaging projection 74f of the elastic piece 74d is reliably engaged with the engaging part 72b of the gear <NUM>, the lengths of the abutting projections 77d of the top plates 77A, 77B, 77C also differ. These three top plates 77A, 77B, 77C are configured to be exchangeable. By exchanging these top plates 77A, 77B, 77C, it is possible to change the abutting position of the abutting projection 77d and the elastic piece 74d.

<FIG> is a drawing showing the relationship between the engaging projections 74f and the engaging parts 72b when using the top plate 77A.

As shown in the drawing, by the abutting projections 77d of the top plate 77A abutting the elastic pieces 74d of the shaft fixing member <NUM>, the engaging projections 74f of the elastic pieces 74d engage with the engaging parts 72b of the gear <NUM>. In this case, when the abutting position of the abutting projections 77d and the elastic pieces 74d changes, the pressing force of the engaging projections 74f on the engaging parts 72b changes. Therefore, by exchanging the top plates 77A, 77B, 77C, the operation timing of the mechanical clutch is changed, and it is possible to change the characteristics of how the top toy 1A moves around.

Specifically, when using the abutting member 77A for which the abutting projections (abutting parts) 77d are formed at a relatively far distance from the engaging projections 74f, it is easy for the elastic pieces 74d to deform, so it is easier for the teeth of the gear <NUM> and the teeth of the guide member <NUM> to engage, and when using the abutting member 77C for which the abutting projections (abutting parts) 77d are formed at a relatively close distance from the engaging projections 74f, engaging is difficult, but after the teeth of the gear <NUM> and the teeth of the guide member <NUM> engage, it is easy to increase the speed at which the top toy 1A moves around.

This top toy 1A is rotationally energized by a launcher that is different from the launcher that energizes the top toy <NUM>, and the same operation and effect as that of the top toy <NUM> are exhibited.

<FIG> is a perspective view of a shaft part 50B which is a modification example. <FIG> is an exploded perspective view of the shaft part 50B in a state seen from the top surface side. <FIG> is an exploded perspective view of the shaft part 50B in a state seen from the bottom surface side.

With this shaft part 50B of the modification example, a rotation shaft <NUM> comprises a shaft body 81a, and a shaft tip member 81b.

The shaft body 81a is formed in a cylinder shape with a large diameter, and an outward flange 81c is formed on the bottom edge part. The bottom edge portion of the outward flange 81c becomes a fitting part 81d in which recesses and projections are formed on the outer peripheral surface.

Meanwhile, on the bottom of the shaft tip member 81b, cylinder shaped small projections 81e that become grounding parts are formed, and the portion above that becomes a large-diameter bottomed cylinder part 81f. The fitting part 81d of the shaft body 81a is fitted inside the recess of this bottomed cylinder part 81f.

An annular gear <NUM> is fitted on the shaft body 81a from above. Two bosses with screw holes 81e are formed on the top surface of the shaft body 81a. The two bosses 81e are provided at positions having point symmetry to each other with respect to the axial center. A friction clutch is configured between the shaft body 81a and the annular gear <NUM>. In a half-clutch state, this friction clutch rolls the annular gear <NUM> along the guide member <NUM>.

The reason the recess is formed on the outer periphery of the shaft body 81a is to adjust the operation timing of the friction clutch.

A ceilinged cylindrical shaped shaft fixing member <NUM> is covered on the shaft body 81a.

The annular gear <NUM> is sandwiched by the bottom edge part of the shaft fixing member <NUM> and the outward flange 81c.

Furthermore, an approximately hexagonal convex part 83b is formed on the shaft fixing member <NUM>, and a female screw 83d is formed in a center hole 83f of this convex part 83b. Two counterbore holes <NUM> corresponding to each of the bosses 81e are formed on the outside of the center hole 83f. This shaft fixing member <NUM> is attached to the rotation shaft <NUM> by screwing male screws (not illustrated) that pass through the counterbore holes <NUM> in the bosses with screw holes 81e.

This shaft part 50B, for example, is joined to a trunk part (not illustrated) by a male screw (not illustrated) screwed into the female screw 83d.

According to the top toy having the shaft part 50B configured in this way, the same actions and effects as those of the top toy <NUM> are exhibited.

<FIG> is an exploded perspective view of a top toy 1B which is a modification example of the top toy <NUM>. <FIG> is an exploded perspective view of the shaft part of the top toy 1B seen from the top surface side. <FIG> is an exploded perspective view of a shaft part 50C seen from the bottom surface side. The parts indicated by the code numbers given in these drawings have the same configuration as the parts given the same numbers in <FIG>, <FIG>, and <FIG>, so their explanation is omitted as appropriate.

The point of difference in this top toy 1B from the top toy <NUM> is the point that a roller 52C is provided instead of the gear <NUM>. The outer peripheral surface of the roller 52C is formed from a material that has strong frictional resistance, such as rubber, a file, a brush, cloth, Velcro (registered trademark), and an adhesive material.

This top toy 1B exhibits particularly meaningful effects with a top toy game table 9B shown in <FIG>. The guide surface of a guide member 93B of the top toy game table 9B in this case is preferably formed from a material that has strong frictional resistance, such as rubber, a file, a brush, cloth, Velcro (registered trademark), and an adhesive material.

When this top toy 1B is released into the battlefield <NUM>, it moves around in reaction in the direction opposite to the rotation direction of the top toy 1B. At this time, the roller 52C integrally rotates with the rotation shaft <NUM>. By this moving around, the roller 52C of the top toy 1B also contacts the guide member 93B. By the impact force at this time, the roller 52C rotates relatively in resistance to the energizing force of the plate springs 55f (see <FIG>) with respect to the rotation shaft <NUM>, and mitigates the impact. As a result, it is easier for the roller 52C to abut the guide member 93B, sliding is suppressed by the frictional resistance of the roller 52C, and in a half-clutch state, the roller 52C is rotated in accordance with the rotation of the rotation shaft <NUM> and moves along the guide member 93B, and the movement of the top toy 1B is accelerated. In other words, it is easier for the rotation of the top toy 1B to be transmitted to the guide member 93B, and possible to accelerate the movement of the top toy 1B.

With the abovementioned embodiments, the guide member <NUM> was provided fixed to the top toy game table <NUM>, but it is also possible to have the guide member <NUM> be a separate body from the top toy game table <NUM>, and for the player to directly hold the guide member <NUM> by hand and use that by approaching the top toy.

With the abovementioned embodiments, one gear that engages with the teeth of the guide member was provided on the rotation shaft, but it is also possible to provide a plurality of gears having a shaft on one circle concentric with the rotation shaft. Alternatively, it is also possible to provide a plurality of teeth forming members on which arc-shaped teeth are formed in the circumferential direction.

It is also possible to replace the gears <NUM>, <NUM>, <NUM> in a case of the other shaft part 50A, the other top toy 1A, and the shaft part 50B of the modification examples with the roller 52C of the top toy 1B.
