Invention of Claim 1 is as above-mentioned, The said grounding part is movable in the axial direction of the said axial part, and when the inclination of the said doll main body with respect to a grounding surface changes, of the said protrusion The ground contact area changes. That is, friction is generated when the protrusions are always in contact with the ground, and the frictional force at this time changes according to the inclination of the doll body. According to such a rotating doll toy, when the frictional force between the protrusion and the ground is large, the rotating motion of the grounding portion is converted into a rolling motion, and the rotating doll toy travels while drawing an arc. Further, when the frictional force between the protrusion and the ground is small, the influence of the protrusion is small, so that the rotating doll toy rotates on the spot by the rotational movement of the grounding portion. In this way, the rotating doll toy runs while drawing an arc or rotates on the spot depending on the ground contact area of the protrusion, so that an interesting toy that performs unexpected movement can be provided.

The invention according to claim 2 is as described above, and when the grounding portion is moved downward, the lower end of the grounding portion is seen from the lower end of the protrusion when viewed in the axial direction of the shaft portion.

Embodiments of the present invention will be described with reference to the drawings.

The rotating doll toy 10 according to the present embodiment includes a doll main body 11 as shown in FIGS. 1 and 2, and the rotating body 14 built in the doll main body 11 rotates, as if rotating. It moves as if dancing.

The rotating body 14 is rotatably supported inside the doll main body 11, and can apply a rotational force using a known means, for example, a rack belt 25 (see FIG. 3). When a rotational force is applied using the rack belt 25, an insertion hole 11 a for inserting the rack belt 25 is provided on the surface of the doll body 11, and the rack belt 25 inserted into the insertion hole 11 a is provided inside the doll body 11. It only has to engage with the pinion 13 of the drive mechanism 12 disposed in the. By pulling out the rack belt 25 inserted through the insertion hole 11a vigorously, the pinion 13 rotates and the drive mechanism 12 operates. The rotational force of the drive mechanism 12 is transmitted to the gear 16 provided integrally with the shaft portion 15 of the rotating body 14, whereby the rotating body 14 rotates.

It should be noted that the means for applying the rotational force to the rotating body 14 is not limited to the rack belt 25, and various known means can be used. For example, a device for applying a rotational force may be provided separately from the rotating doll toy 10, a rotational force may be applied using a string or the like, or the rotating body 14 may be pressed against the ground to rotate. Rotating force may be applied by sliding on, or a rotating force may be applied by a built-in motor or an external motor.

Note that the shaft portion 15 of the rotating body 14 is rotatably supported by a bearing portion (not shown) fixed to the doll main body 11. For this reason, the doll main body 11 does not rotate integrally with the rotating body 14, but when the rotating body 14 rotates, the rotation of the shaft portion 15 is transmitted to the doll main body 11 via the bearing portion, and the doll main body 11 rotates. A force to try to generate is generated. A flywheel 17 for stabilizing the rotation of the rotating body 14 is fixed to the shaft portion 15 of the rotating body 14.

As shown in FIG. 4, a grounding portion 18 is provided at the tip of the shaft portion 15 of the rotating body 14. The grounding portion 18 is provided so as to protrude below the doll main body 11 so that the rounded tip can be grounded.

A cylindrical portion 20 is provided on the lower surface of the doll main body 11 so as to cover the periphery of the grounding portion 18. This cylindrical part 20 forms the protrusion 21 because a part of lower end edge protrudes below. As shown in FIG. 4C, the protrusion 21 is formed in an arc shape with the shaft portion 15 (grounding portion 18) as the center in plan view. Further, the projection 21 is provided on the rear side of the doll main body 11 so as to cover the rear side of the grounding portion 18. The tip surface of the protrusion 21 is a flat surface perpendicular to the shaft portion 15, and this tip surface is formed in an arc shape similar to the cross-sectional shape shown in FIG.

The lateral width of the protrusion 21 in front view is formed to be substantially the same as the lateral width of the grounding portion 18, and as shown in FIG. 1, the projection 21 is hidden behind the grounding portion 18 when viewed from the front. Yes. Further, the protrusion 21 and the grounding portion 18 are arranged close to each other so that the protrusion 21 is not conspicuous. In the present embodiment, as shown in FIG. 4C, the gap G between the projection 21 and the grounding portion 18 in plan view is set to be smaller than the diameter D of the grounding portion 18.

In addition, as shown in FIG. 4, the flywheel 17 is accommodated in the inside of the doll main body 11 with a space | interval up and down. For this reason, the flywheel 17 can be moved up and down, and the rotating body 14 (shaft portion 15) moves in the axial direction with respect to the doll body 11 within this vertically movable range (2 mm in the present embodiment). It is free.

When the shaft portion 15 is moved to the lowest position, as shown in FIGS. 4A and 4B, the vertical plane passing through the lower end of the grounding portion 18 is positioned below the lower end of the protrusion 21. It has become. At this time, the distance W1 from the vertical plane passing through the lower end of the grounding portion 18 to the lower end of the protrusion 21 is preferably set to about 1 to 1.5 mm.

When the shaft portion 15 is moved to the uppermost position, as shown in FIGS. 4D and 4E, the vertical plane passing through the lower end of the grounding portion 18 is positioned above the lower end of the protrusion 21. It is like that. At this time, the distance W2 from the vertical plane passing through the lower end of the grounding portion 18 to the lower end of the protrusion 21 is preferably set to about 0.5 to 1 mm.

Rotating doll toy 10 configured in this way can be placed and played on a mortar-shaped traveling board 26 as shown in FIG. 6, for example. When the traveling board 26 shown in FIG. 6 is used, the rotating doll toy 10 operates as follows.

First, the flywheel 17 of the rotating doll toy 10 is rotated using the rack belt 25 or the like and placed on the traveling board 26. When the flywheel 17 is rotated, a force to keep the shaft portion 15 vertical works, so that the rotating doll toy 10 maintains a vertical posture as much as possible. At this time, the doll main body 11 and the rotating body 14 are lowered by their own weight, and as shown in FIG. 5, the tip surface of the protrusion 21 and the tip of the grounding portion 18 are both grounded with respect to the ground. Then, as shown in FIG. 5 (a), when the rotating doll toy 10 is tilted to the opposite side of the protrusion 21, as shown in FIG. 5 (b), the tip of the protrusion 21 is a line or Ground on the surface. When the tip of the projection 21 touches the line or surface, a large frictional force is generated between the projection 21 and the ground. Therefore, the rotating doll toy 10 slides and moves in an arc (see arrow X in FIG. 6). ). At this time, the rotating doll toy 10 moves in the inner circumferential direction so that the protrusion 21 comes in the outer circumferential direction.

Further, as shown in FIG. 5 (c), when the rotating doll toy 10 is tilted toward the protrusion 21, the tip of the protrusion 21 is grounded at a point as shown by the contact point P2 as shown in FIG. 5 (d). . When the tip of the protrusion 21 is grounded at a point, the frictional force generated between the protrusion 21 and the ground is reduced. When the frictional force generated between the protrusion 21 and the ground becomes small, the doll body 11 rotates on the spot (see arrow Y in FIG. 6). That is, since the doll body 11 is affected by the rotational force of the rotating body 14 via the bearing portion, a force to gently rotate is applied, and the frictional force generated between the protrusion 21 and the ground is large. This rotation is prevented, but when the frictional force generated between the protrusion 21 and the ground becomes small, it rotates.

If the posture of the rotating doll toy 10 changes and the rotating doll toy 10 tilts to the opposite side of the protrusion 21, a large frictional force is generated again between the ground and the protrusion 21, so that the rotating doll toy 10 draws an arc. Move sideways. Further, when the posture of the rotating doll toy 10 is changed and the rotating doll toy 10 is tilted toward the protrusion 21, the doll main body 11 rotates on the spot.

As described above, according to the present embodiment, the rotating doll toy 10 repeatedly performs the operation of running while drawing an arc and the operation of rotating on the spot alternately by changing the posture. In particular, in the present embodiment, since the protrusion 21 and the grounding portion 18 are arranged close to each other, the frictional force generated between the protrusion 21 and the ground changes greatly when the rotating doll toy 10 is slightly inclined. , Movement changes are more likely to occur.

In the above-described embodiment, the mortar-shaped traveling board 26 is used to make the posture of the rotating doll toy 10 easy to change. However, the present invention is not limited to this, and a flat board surface may be run. You may make it change the attitude | position of the rotation doll toy 10 by making the rotation doll toy 10 contact an obstruction.

In the above-described embodiment, the movement is changed when the posture is changed. However, the movement is not limited to this, and the movement may be changed by changing the frictional force of the ground. For example, if a slippery part is provided on a part of the traveling board 26, the frictional force generated between the protrusion 21 and the ground when the rotating doll toy 10 rotates on the slippery part is reduced, The doll body 11 can be rotated on the spot.

Moreover, the rotating doll toy 10 according to the present embodiment can also run on the rail 30 as shown in FIGS. This rail 30 is provided with a friction imparting material 32 near one side of a rail body 31 having a side wall 31a, and a portion where the friction imparting material 32 is not provided serves as a travel path 33. The friction imparting material 32 is made of a material having a higher coefficient of friction than the rail body 31 such as rubber, and is engaged with the side surface of the grounding portion 18 when the grounding portion 18 of the rotating doll toy 10 enters the travel path 33. It is supposed to be.

As shown in FIG. 8A, the interval between the side walls 31a on both sides is substantially the same as or slightly larger than the width of the cylindrical portion 20, and the side wall 31a is cylindrical. The rotating doll toy 10 can travel on the traveling path 33 by guiding the shape portion 20.

It should be noted that which side of the rail body 31 is provided with the friction imparting member 32 may be determined according to the rotation direction of the rotating body 14. In the present embodiment, the rotating body 14 rotates in the clockwise direction in plan view. In this case, the friction applying material 32 may be provided on the right side in the traveling direction of the rail body 31. On the other hand, when the rotating body 14 rotates counterclockwise in plan view, the friction applying material 32 may be provided on the left side in the traveling direction of the rail body 31.

As shown in FIG. 7A, the rail 30 according to the present embodiment is arranged to be an uphill, and when the rotating doll toy 10 is guided to the rail 30, the doll body 11 moves forward (in detail). It is configured to climb up along the rail 30 in a state of facing diagonally forward.

The reason why the doll main body 11 faces forward is that when the flywheel 17 rotates, a force to keep the shaft portion 15 vertical is working. That is, in the structure in which the protrusion 21 protrudes below the grounding portion 18 as in the present embodiment, the protrusion 21 is on the lower side (backward) of the hill than the grounding portion 18 as shown in FIG. Since the axial part 15 becomes near perpendicular | vertical sometimes, the attitude | position of the rotation doll toy 10 is stabilized. In other words, as shown in FIG. 9, when the projection 21 is on the upper side (front) of the slope than the grounding portion 18, the shaft portion 15 does not become nearly vertical, so the posture of the rotating doll toy 10 is not stable. Therefore, even if the doll main body 11 is placed on the rail 30 backward as shown in FIG. 9, it is not stable in this state, and the doll main body 11 as shown in FIG. The doll main body 11 is rotated until it stabilizes in this posture. At this time, since the protrusion 21 fits in the traveling path 33, the doll main body 11 faces obliquely forward (see FIG. 7B).

And as P3 of Fig.8 (a) shows, since the friction imparting material 32 is engaging with the side surface (the taper surface near the friction imparting material 32 a little from the center) of the grounding part 18, the doll main body 11 is In a state of facing forward, the ground contact portion 18 rotates along the friction imparting material 32, and the rotating doll toy 10 climbs uphill along the rail 30.

The rail 30 may be provided connected to the traveling board 26 as shown in FIG. 6, for example. In this way, for example, the rotating doll toy 10 moving on the traveling board 26 enters the rail 30 and moves on the rail 30, or the rotating doll toy 10 moving on the rail 30. Can be guided to the traveling board 26, so that the rotating doll toy 10 can move in a three-dimensional space.

As described above, according to the present embodiment, the grounding portion 18 is movable in the axial direction of the shaft portion 15, and when the inclination of the doll body 11 with respect to the grounding surface changes, The ground contact area of the protrusion 21 changes. That is, friction is caused by the projection 21 coming into contact with the ground, and the frictional force is changed by changing the inclination of the doll main body 11. According to such a rotating doll toy 10, when the frictional force between the protrusion 21 and the ground is large, the rotating motion of the grounding portion 18 is converted into a rolling motion, and the rotating doll toy 10 travels while drawing an arc. Further, when the frictional force between the protrusion 21 and the ground is small, the influence of the protrusion 21 is small, so that the rotating doll toy 10 rotates on the spot by the rotational movement of the grounding portion 18. As described above, the rotating doll toy 10 travels while drawing an arc or rotates on the spot depending on the contact area of the protrusion 21, so that it is possible to provide an interesting toy that performs unexpected movement. .

Further, when the grounding portion 18 is moved to the lowest position, the lower end of the grounding portion 18 is positioned below the lower end of the protrusion 21 when viewed in the axial direction of the shaft portion 15, and the grounding portion 18 Is moved to the uppermost position, the lower end of the grounding portion 18 is positioned higher than the lower end of the protrusion 21 when viewed in the axial direction of the shaft portion 15. According to such a configuration, even when the shaft portion 15 is inclined toward the protrusion 21 or when the shaft portion 15 is inclined toward the opposite side of the protrusion 21, both the grounding portion 18 and the protrusion 21 are reliably grounded. be able to.

The protrusion 21 is provided on the rear side of the doll body 11. According to such a rotating doll toy 10, the rotating doll toy 10 can be run along the rail 30 by engaging the friction imparting material 32 of the rail 30 with the side surface of the grounding portion 18, and Even when the rail 30 is made uphill, the doll body 11 climbs along the rail 30 with the doll body 11 facing forward.

Further, since the periphery of the grounding portion 18 is covered with the cylindrical portion 20, the shaft portion 15 can be reinforced by the cylindrical portion 20. Moreover, it can cover so that a hand may not touch the axial part 15. FIG. Further, since the shaft portion 15 (grounding portion 18) and the cylindrical portion 20 are integrated and the protrusion 21 is not conspicuous, the shaft portion 15 and the cylindrical portion 20 may be designed to be regarded as legs of the doll body 11. And the design is improved.

The protrusion 21 is formed in an arc shape with the shaft portion 15 as the center. According to such a structure, since the frictional force generated between the protrusion 21 and the ground changes greatly only by slightly tilting the rotating doll toy 10, it is possible to easily cause a change in movement.

Further, the distance between the protrusion 21 and the grounding portion 18 in plan view is made smaller than the diameter of the grounding portion 18. That is, since the protrusion 21 and the ground contact portion 18 are brought close to each other, the frictional force generated between the protrusion 21 and the ground is greatly changed only by a slight tilt of the rotating doll toy 10, causing a change in movement. Can be made easier.
