Description

The present invention relates to a top toy using a gyro motor. In particular, the present invention relates to multiple tops in which the upper and lower adjacent portions have different rotational directions.

FIG. 11 shows a general perspective view of a conventional toy used by children for play. A self-contained body 11 and a top axis 14 are provided above and below the center of the substantially conical body 11, and the top of the top is rotated with the thumb and forefinger to rotate the top body. Therefore, the conventional top is only one-way rotation.

Further, the shaft 14 on the surface side that comes into contact with the spinning of the top is made of a material different from the conical body 11, and a hole is formed in the center of the conical body, and the tip is pointed. Some have a conical shape, and others have the shaft core 14 manufactured integrally with a conical body by cutting or the like.
The reason why the shaft core shape and the shaft core are made to be the center axis of the top is to reduce precession during rotation of the top as much as possible.

Further, in Patent Document 1, the shape up to the tip of the head is a hemisphere, an ellipsoid, or a foggy shape having a tip, and the bottom shape is a sphere so that the top is kept tilted by precession, and the center of gravity There is also a predation-based topography that looks like a big top spinning around the center, and when the top is stationary, the pattern on the rotating body looks the same as when stationary. is there.

However, since the above-mentioned conventional top is only one-way rotation, there is a lack of fun as a toy.

In order to solve the above-described problems, the present invention stacks a plurality of rotating tops, and the center axis of the spherical body 13 which is a spherical contact portion made of a part of a sphere or an elliptical sphere coincides with the center axis of the top It is a new topping that is integrated so that Here, an axis that penetrates the integrated central axis on one side is provided. The lower shaft of the bottom top is loosely inserted into the hole of the top. The upper top is arranged so that the shaft center provided so that the central axis of the upper top matches the axis of the lower top is detachable and fixed on the same axis as the axis of the lower top. As described above, the present invention applies a rotational force by strongly repelling the lowermost top and is characterized in that the adjacent lower top and top tops rotate in different rotational directions. That is, the main role of the present invention is to provide multiple tops.
Since the shaft core 14 is loosely inserted into the hole of the top of the top and the spherical body 13 actively uses the precession while contacting the periphery of the hole, the adjacent lower top and top top The directions of rotation are opposite to each other.

As described above, in the present invention, adjacent tops are rotated in opposite directions, and thus cannot be obtained from the prior art by attaching feathers or ornaments to the multiple tops or by devising colors and patterns. New effects can be obtained.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that components with similar functions or structures are given the same names and symbols as much as possible, and necessary explanations are given for the first appearance, and only when there are changes or feature points when reappearing .

FIG. 1 shows a triple top as an example of the multiple top of the present invention. As shown in FIG. 1, the multiple top solo of the present invention comprises a bottom single top 1, a single top 2, an upper single top 3, and a support base 20.
Here, as shown in FIG. 6, the single top 2 is provided with a top / bottom projection 15 of a self-tucking shaft with a hole at its center, and the center axis diameter is set slightly larger than that of the shaft 14. Therefore, this single top 2 is structured to be landed and inserted on top of the top 1 so as to be rotatable with respect to the stone and the axis 14.
On the other hand, the single top 3 is inserted and directly connected to the shaft core 14 on the central axis.
In the operation of the triple top, if the lower top 1 is rotated by hand, the top 2 is rotated in the opposite direction, and the top 3 is directly connected to the shaft, so that the top 1 rotates in the same direction. Accordingly, the tops 1, 2, and 3 exhibit rotation phenomena in opposite directions in the vertical direction.

FIG. 2 is a longitudinal sectional view showing an example of a single top unit 10 constituting the multiple top music in FIG. The spherical body 13, which is a spherical contact portion formed of a part of a sphere or an elliptical sphere, is integrated so that the central axis of the spherical body 13 coincides with the central axis of the top body 11, and penetrates the integrated central axis on one side. A shaft core 14 is provided.

Further, as shown in FIG. 3, the top body 11 may be provided with a hand-playing convex portion 12 for applying a rotational force in a top-down manner. The hand-playing convex portion 12 may be provided on at least one of the single tops constituting the multiple tops. Further, the hand repelling convex portion 12 provided in the single top must be provided in an arrangement that does not impair the rotational balance. Therefore, it becomes two or more.
Moreover, what is necessary is just to provide in the vertex of a regular polygon in order to make the arrangement | positioning which does not impair rotation balance.

FIG. 5 shows a state in which the lowermost top 1 is supported.
The lower shaft core 14 of the lowermost top 1 is loosely inserted into the hole of the support base hole 21 of the support base 20.
The upper top 2 in FIG. 7 has a top / bottom projection 15 of a topless hook that is provided so that the central axis of the upper top matches the axis 14 of the lowermost top 1. This is configured to have a diameter larger than that of the shaft core 14 on the same axis. FIG. 6 shows this state, and a hole is provided in the central axis and the pipe is arranged. In this case, a rotational force is applied by strongly flicking one lowermost top 1 constituting a multiple top.

The support base 20 needs to have a size and weight suitable for the number and weight of the multiple tops to support the entire multi-stage top, and the support base hole 21 penetrates the upper and lower surfaces of the support base 20 in this example. However, it does not necessarily have to penetrate.

When the support base hole 21 does not penetrate vertically and the lower part is closed in the middle, the spherical body 13 of the lowermost top is in contact with the wall surface of the support base 20 around the support base hole 21 while precessing. In order to make the movement, the depth of the support base hole must be deeper than the length of the shaft core 14 protruding from the spherical body 13 at the bottom.

Next, the operation principle of the multiple top music of the present invention will be described.
FIG. 4 is a diagram for explaining the operating principle of the present invention. It is assumed that the columnar rotating body 32 rotates in the CW direction. At this time, it is considered that the columnar rotating body 32 rotates in contact with the cylindrical inner wall 31 as illustrated. In this case, the columnar rotator 32 moves while rolling on the cylinder inner wall 31 due to contact friction with the cylinder inner wall 31, and the locus of the center point of the columnar rotator 32 is a circular motion in the CCW direction.

FIG. 3 is a longitudinal sectional view showing the operation principle of the present invention.
In FIG. 3, the top unit 10-1 is the bottom unit top unit 1, and when the hand-playing convex portion 12 of the top unit 11 is repelled in the CW direction, the top unit 10-1 is inclined as shown in the CW direction. Rotate. In other words, it is rotating while precessing.
Therefore, the spherical body 13 provided below the top unit 10-1 rotates while rolling on the wall surface of the upper surface of the support base 20. That is, according to the principle described with reference to FIG. 4, the locus at the center of the tip of the shaft core 14 is a circular motion in the CCW direction.

Therefore, in FIG. 8, if there is a top 11-11 as shown in the figure at the top of the axis of the top 1, if the hole diameter 11-4 on the central axis is set larger than the center, the pan 14 of the top 14 is turned. In this way, the top 4 (11-4) rotates in the opposite direction to the top 1.
However, if the top 4 is not very light, it cannot be rotated in reverse.

When the top 1 (11-1) of FIG. 7 is rotated by hand, the phenomenon that the top 2 (11-2) rotates in reverse is based on the following principle. As described with reference to FIG. 3, when the top body 1 (11-1) is rotated by hand, the shaft core 14 rotates (CW rotation) and is accompanied by reciprocal rotation (CCW).
FIG. 12 shows such a state, given a _{M Z} that produces rotation of top 1 (CW direction), _M 1, _{M 2} occurs as shown. On the contrary, when M ₁ and M ₂ are applied, M _Z is generated. This is known as the principle of the gyro moment motor configured as shown in FIG.
The _M 1, _{M 2} acts to top member 2 of FIG. Accordingly, the torque moment acts in the direction in which M ₁ and M ₂ work (CCW direction) via the frictional force (friction moment) between the top body 1 (11-1) and the top body 2 (11-2). The body 2 (11-2) rotates in the reverse direction. That is, these M ₁ and M ₂ are the main roles of the reverse rotational force.

The reason why the top covered top body 4 (11-4) in FIG. 8 rotates in the direction opposite to that of the bottom top body 1 (11-1) is due to the panning phenomenon due to the revolution (CCW) of the shaft core 14 in FIG.

FIG. 1 shows a triple top as an example of a multiple top configuration according to the present invention. A specific embodiment will be described.
The top body 11-1 of the bottom single-piece top 1 is made by punching a metal plate in order to increase the inertia at the time of rotation, and the hand-playing convex portion 12-1 of the top body is a dynamic balance at the time of rotation. Four are provided at 90 ° positions, which are the vertices of a regular tetragon.

The solo main body 11-2 of the single solo music 2 is made of plastic. The top body 11-3 of the upper single top 3 is also made of plastic. The solo main body 11-2 of the single top 2 has a larger outer diameter and a smaller thickness than the top main body 11-3 of the upper single top 3. The plastic top may be made of paper.

Also, the outer diameter of the upper top is successively made smaller than the outer diameter of the lower top so that each of the three singles of the triple top can be clearly seen. If the outer diameter of the main body 11-1 of the lowermost top solo 1 is set to 100, the balance of the appearance is good when the outer diameter of the main body 2 of the single top 2 and the upper single top 3 is set to about 60 and 35.

Further, the support base 20 needs an appropriate weight to support the entire triple top, and the material is stainless steel in this embodiment.
Further, as described in the operation principle, the spherical body 13 rotates while rolling on the wall surface of the upper surface of the support base 20, so that the support base hole 21 of the support base 20 improves the rolling of the wall surface as shown in FIG. You may provide the support stand hole chamfering part 22 in a contact part.

Further, as explained in the above operating principle, the support base hole 21 of the support base 20 has an outer diameter of φ1.2 mm, and the shaft core 14 of the lowermost single top 1 has a diameter of φ1.0 mm.
FIG. 7 is a longitudinal sectional view showing an embodiment of the double top music of the present invention.
Although the lower top 1 is not different from the configuration of FIG. 3, the shaft core 15 of the lower single top 1 passes through the shaft hole 16-2 of the upper single top 2.
Therefore, in this case, a cylindrical shaft column 15-2 having a shaft hole 16-2 passing through is provided on the side in contact with the lower top 1 so that an appropriate space is maintained between the upper and lower tops 1 and 2, so that the lower top 1 is in contact. To.
Even in this configuration, if the hand-pulling portion 12-1 of the top body of the bottom top 1 is repelled and a rotational driving force is applied, the top and bottom top and bottom tops 1 and 2 rotate in opposite directions, and a double-rotation top Realized.

FIG. 9 is a quadruple solo music in which the triple top music of FIG. 1 is covered with the top music 11-4 of FIG. It is obvious from the above explanation that the adjacent top and bottom tops reversely rotate with each other.

FIG. 10 shows the configuration of a five-piece top. This is a structure in which the main body top 2 and top 3 shown in FIG. The top 4 rotates reversely on the same principle as the top 2 and the top 5 is configured in the same manner as the top 3, so it rotates directly in the same direction as the top body 1, 3 directly connected to the shaft core.

If the main body top 2 and the top 3 of FIG. 1 are further stacked, the top of the center shaft of FIG. 10 is further extended, and the cover rotor top of FIG. 8 is added. Become a religion. That is, in general, a multiple gyro motor top can be configured.

If you attach various patterns to the surface of each top of the Honda Gyro and Motor Top, it will be a more attractive toy. In particular, since the surface of the uppermost top main body can be seen well, it is effective to give a pattern to this portion.
FIGS. 13A to 13G are examples of the pattern.
Due to the rotation of the top body, the pattern is different from the still picture.
For example, the three leaves in FIG. 13A become a four-leaf picture.

FIG. 8 is also an example of a double top, but in the double top of this FIG. The rotation pattern (CCW rotation) is in the opposite direction to the direction 4 (for example, CW rotation). This is demonstrated in FIGS. 13B to 13G. In particular, the hexagonal star in FIG. 13B looks like a pentagonal star, and the square picture in FIG. 13D is transformed into a triangular picture or the like.
